RESUMEN
BACKGROUND: Around 4% of women receive an endometrial cancer diagnosis before turning 40, mainly those without prior childbirth experience and a strong desire to preserve their ability to conceive. Consequently, for young patients diagnosed with atypical endometrial hyperplasia (AEH) or early endometrial carcinoma (EC), a fertility-preserving approach employing high-dose oral progesterone has been adopted. However, previous research has shown a notable relapse rate. Furthermore, the extended use of substantial oral progesterone doses may hinder ovarian function and raise the risk of weight gain, liver issues, blood clotting, and breast cancer. We previously assessed the clinical effectiveness and pregnancy outcomes of gonadotropin-releasing hormone agonist (GnRH-a) based re-treatment for women with EC and AEH who did not respond to oral progestin therapy but achieved favorable treatment results and reproductive outcomes. METHODS: This study will be an open-label, two-armed, randomized, investigator-initiated multicenter trial evaluating the combination of GnRH-a with the levonorgestrel-releasing intrauterine system or the combination of GnRH-a with an aromatase inhibitor (comprising a subcutaneous GnRH-a injection every 4 weeks and daily oral letrozole 2.5 mg). A total of 226 participants will be randomly allocated to one of the two treatment groups in a 1:1 ratio. The primary objective is to determine the effectiveness of GnRH-a-based re-treatment in achieving a complete response (CR) at 24 weeks for patients with AEH or EC. Secondary objectives include assessing the pregnancy rate 12 weeks after treatment, as well as post-treatment pregnancy outcomes and the rate of recurrence. ETHICS AND DISSEMINATION: The protocol received approval from the Institutional Review Board of Peking Union Medical College Hospital and from boards at five other institutions. The trial will adhere to the principles outlined in the World Medical Association's Declaration of Helsinki and follow Good Clinical Practice standards. The trial results will be disseminated through publication in a peer-reviewed journal. CONCLUSIONS: Prospective evidence supporting conservative treatment for EC and AEH is limited. There is a need for new approaches that can achieve higher CR rates with fewer side effects. This trial will assess the effectiveness of GnRH-a-based fertility-sparing treatment in obese women and recurrent patients, offering a promising alternative for patients with EC and AEH.

RATIONALE: Hepatocellular carcinoma is the most common type of liver cancer, accounting for 70% to 85% of individuals with primary liver cancer. Tamoxifen has been evaluated in randomised clinical trials in people with hepatocellular cancer. The reported results have been inconsistent. OBJECTIVES: To evaluate the benefits and harms of tamoxifen or tamoxifen plus any other anticancer drugs compared with no intervention, placebo, any type of standard care, or alternative treatment in adults with hepatocellular carcinoma, irrespective of sex, administered dose, type of formulation, and duration of treatment. SEARCH METHODS: We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, MEDLINE, Embase, three other databases, and major trials registries, and handsearched reference lists up to 26 March 2024. ELIGIBILITY CRITERIA: Parallel-group randomised clinical trials including adults (aged 18 years and above) diagnosed with advanced or unresectable hepatocellular carcinoma. Had we found cross-over trials, we would have included only the first trial phase. We did not consider data from quasi-randomised trials for analysis. OUTCOMES: Our critical outcomes were all-cause mortality, serious adverse events, and health-related quality of life. Our important outcomes were disease progression, and adverse events considered non-serious. RISK OF BIAS: We assessed risk of bias using the RoB 2 tool. SYNTHESIS METHODS: We used standard Cochrane methods and Review Manager. We meta-analysed the outcome data at the longest follow-up. We presented the results of dichotomous outcomes as risk ratios (RR) and continuous data as mean difference (MD), with 95% confidence intervals (CI) using the random-effects model. We summarised the certainty of evidence using GRADE. INCLUDED STUDIES: We included 10 trials that randomised 1715 participants with advanced, unresectable, or terminal stage hepatocellular carcinoma. Six were single-centre trials conducted in Hong Kong, Italy, and Spain, while three were conducted as multicentre trials in single countries (France, Italy, and Spain), and one trial was conducted in nine countries in the Asia-Pacific region (Australia, Hong Kong, Indonesia, Malaysia, Myanmar, New Zealand, Singapore, South Korea, and Thailand). The experimental intervention was tamoxifen in all trials. The control interventions were no intervention (three trials), placebo (six trials), and symptomatic treatment (one trial). Co-interventions were best supportive care (three trials) and standard care (one trial). The remaining six trials did not provide this information. The number of participants in the trials ranged from 22 to 496 (median 99), mean age was 63.7 (standard deviation 4.18) years, and mean proportion of men was 74.7% (standard deviation 42%). Follow-up was three months to five years. SYNTHESIS OF RESULTS: Ten trials evaluated oral tamoxifen at five different dosages (ranging from 20 mg per day to 120 mg per day). All trials investigated one or more of our outcomes. We performed meta-analyses when at least two trials assessed similar types of tamoxifen versus similar control interventions. Eight trials evaluated all-cause mortality at varied follow-up points. Tamoxifen versus the control interventions (i.e. no treatment, placebo, and symptomatic treatment) results in little to no difference in mortality between one and five years (RR 0.99, 95% CI 0.92 to 1.06; 8 trials, 1364 participants; low-certainty evidence). In total, 488/682 (71.5%) participants died in the tamoxifen groups versus 487/682 (71.4%) in the control groups. The separate analysis results for one, between two and three, and five years were comparable to the analysis result for all follow-up periods taken together. The evidence is very uncertain about the effect of tamoxifen versus no treatment on serious adverse events at one-year follow-up (RR 0.44, 95% CI 0.19 to 1.06; 1 trial, 36 participants; very low-certainty evidence). A total of 5/20 (25.0%) participants in the tamoxifen group versus 9/16 (56.3%) participants in the control group experienced serious adverse events. One trial measured health-related quality of life at baseline and at nine months' follow-up, using the Spitzer Quality of Life Index. The evidence is very uncertain about the effect of tamoxifen versus no treatment on health-related quality of life (MD 0.03, 95% CI -0.45 to 0.51; 1 trial, 420 participants; very low-certainty evidence). A second trial found no appreciable difference in global health-related quality of life scores. No further data were provided. Tamoxifen versus control interventions (i.e. no treatment, placebo, or symptomatic treatment) results in little to no difference in disease progression between one and five years' follow-up (RR 1.02, 95% CI 0.91 to 1.14; 4 trials, 720 participants; low-certainty evidence). A total of 191/358 (53.3%) participants in the tamoxifen group versus 198/362 (54.7%) participants in the control group had progression of hepatocellular carcinoma. Tamoxifen versus control interventions (i.e. no treatment or placebo) may have little to no effect on adverse events considered non-serious during treatment, but the evidence is very uncertain (RR 1.17, 95% CI 0.45 to 3.06; 4 trials, 462 participants; very low-certainty evidence). A total of 10/265 (3.8%) participants in the tamoxifen group versus 6/197 (3.0%) participants in the control group had adverse events considered non-serious. We identified no trials with participants diagnosed with early stages of hepatocellular carcinoma. We identified no ongoing trials. AUTHORS' CONCLUSIONS: Based on the low- and very low-certainty evidence, the effects of tamoxifen on all-cause mortality, disease progression, serious adverse events, health-related quality of life, and adverse events considered non-serious in adults with advanced, unresectable, or terminal stage hepatocellular carcinoma when compared with no intervention, placebo, or symptomatic treatment could not be established. Our findings are mostly based on trials at high risk of bias with insufficient power (fewer than 100 participants), and a lack of trial data on clinically important outcomes. Therefore, firm conclusions cannot be drawn. Trials comparing tamoxifen administered with any other anticancer drug versus standard care, usual care, or alternative treatment as control interventions were lacking. Evidence on the benefits and harms of tamoxifen in participants at the early stages of hepatocellular carcinoma was also lacking. FUNDING: This Cochrane review had no dedicated funding.

BACKGROUND: Does incorporating Cyclin-dependent kinase 4/6 (CDK4/6) inhibitors into endocrine therapy (ET) effectively enhance survival outcomes, notably overall survival (OS), among individuals with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer? This remains a clinical controversy. We compared the antitumor efficacy and adverse effects (AEs) between CDK4/6 inhibitors + ET (CET) and placebo + ET (PET) by conducting a phase III randomized controlled trials (RCTs) based meta-analysis. METHODS: Seven databases were searched to identify eligible studies, comprising Phase III RCTs comparing CET to PET. The primary endpoints were OS and progression-free survival (PFS), with secondary endpoints including responses and adverse events (AEs). RESULTS: Seven RCTs (DAWNA-2, MONALEESA-2, MONALEESA-3, MONALEESA-7, MONARCH-3, PALOMA-2, and PALOMA-4) were included. The CET group exhibited significantly improved OS (HR: 0.81 [0.74, 0.88]), PFS (HR: 0.57 [0.52, 0.63]), objective response rate (RR: 1.31 [1.20, 1.43]), and clinical benefit rate (RR: 1.11 [1.07, 1.15]). These benefits were consistent across almost all subgroups. Additionally, the CET group showed better overall survival rates (OSR) from 24 to 60 months (OSR 24-60 m) and progression-free survival rates (PFSR) from 6 to 60 months (PFSR 6-60 m). However, more total AEs, grade 3-5 AEs, and serious AEs were found in CET group. The top 5 grade 3-5 AEs in the CET group were neutropenia (59.39%), leukopenia (24.11%), decreased white blood cell count (12.99%), hypertension (7.03%), and increased alanine aminotransferase (5.91%). CONCLUSIONS: The superiority of CET over PET in HR+/HER2- advanced breast cancer is evident, showing improved survival and responses. Nonetheless, the higher incidence of AEs, specifically hematologic AEs, requires cautious attention.

BACKGROUND/AIM: Endocrine therapy is the standard treatment for hormone receptor-positive (HR+) breast cancer (BC). Yet, it is accompanied by treatment-related toxicities, leading to poor treatment adherence, high relapse, and low rates of survival. While pharmacogenomic variants have the potential to guide personalized treatment, their predictive value is inconsistent across published studies. MATERIALS AND METHODS: To systematically assess the literature's current landscape of pharmacogenomics of endocrine therapy-related adverse drug effects, systematic searches in MEDLINE, Embase, Cochrane CENTRAL, Google Scholar and PharmGKB databases were conducted. RESULTS: We identified 87 articles. Substantial heterogeneity and variability in pharmacogenomic effects were evident across studies, with many using data from the same cohorts and predominantly focusing on the Caucasian population and postmenopausal women. Meta-analyses revealed Factor V Leiden mutation as a predictor of thromboembolic events in tamoxifen-treated women (p<0.0001). Meta-analyses also found that rs7984870 and rs2234693 were associated with musculoskeletal toxicities in postmenopausal women receiving aromatase inhibitors (p<0.0001 and p<0.0001, respectively). CONCLUSION: Overall, the current body of evidence regarding the potential role of pharmacogenomics in endocrine therapy-related toxicity in BC remains largely inconclusive. Key concerns include the heterogeneity in toxicity definitions, lack of consideration for genotype-treatment interactions, and the failure to account for multiple testing. The review underscores the necessity for larger and well-designed studies, particularly with the inclusion of premenopausal women and non-Caucasian populations.

Background and Objectives: The purpose of the present study was to compare the results of colposcopic biopsies in patients with breast cancer and those who tested positive for HPV in cervix uteri cytological screenings, with a control group of HPV-positive individuals without breast cancer. Additionally, through this study, we aimed to investigate the impact of tamoxifen treatment, an anti-oestrogen drug used following breast cancer treatment, on histopathological changes. Breast cancer is the most common type of cancer and cause of death in women worldwide. Cervical cancer ranks as the second most prevalent form of cancer among women globally, with prevalence rates ranking just behind those of breast cancer. Human papillomavirus (HPV) positivity is a requirement for the development of cervical cancer, although it is not the sole factor responsible. Materials and Methods: A comparison was made between the histopathological results of 52 patients diagnosed with breast cancer, who tested positive for HPV in routine cervical cytological screenings and underwent colposcopic biopsy, and 230 cases without any abnormalities. A study was conducted to compare healthy individuals between the ages of 30 and 65 who were diagnosed with breast cancer and those who did not have breast cancer. The participants underwent HPV screening as part of the national cervical cytology screening programme. Results: The average age of those diagnosed with breast cancer was 46.73 ± 7.54; in comparison, the average age of participants in the control group was 47.49 ± 7.95. There was no statistically significant difference in age between the two groups (p: 0.530). A total of 51 cases (98.1%) of breast cancer were found to have actively used the anti-oestrogen drug tamoxifen for a duration ranging from at least 6 months to 5 years. One patient (1.9%) in the breast cancer group did not use tamoxifen. During routine cervical cytological screenings, it was observed that both breast cancer cases and healthy cases tested positive for HPV. The most commonly detected types of HPV in both groups were HPV 16 and 18, with rates of 73.1% noted in the breast cancer group and 92.6% noted in the healthy group, results consistent with the rates found in the general population. HPV 16 was found in 58.7% of participants in the control group and 42.3% of participants in the breast cancer group. There was a statistically significant difference between the two groups (p: 0.032). There was no statistically significant difference observed between the two groups in terms of normal, high-grade cervical intraepithelial lesions (HGSILs); low-grade cervical intraepithelial lesions (LGSILs); and chronic cervicitis histopathological lesions based on colposcopic and endocervical biopsy results, smear cytology, and HPV results (p-values of 0.913 and 0.877, respectively). Conclusions: Our study results indicate that tamoxifen treatment, an anti-oestrogen drug administered for chemoprevention purposes in the management of breast cancer, does not lead to an increase in abnormal histological changes in the cervix uteri. In all cases of breast cancer, gynaecological examination and cervical cytological screening should be advised.

BACKGROUND: Women with newly diagnosed hormone receptor-positive breast cancer are offered adjuvant endocrine therapy (AET). Despite the survival benefits of the therapy, a significant proportion of breast cancer patients do not adhere to the anti-hormonal medication. AIMS: The purpose of this study was to analyse demographic, social, psychological and treatment-related factors influencing whether women diagnosed with early-stage breast cancer were adherent to offered therapy. MATERIALS AND METHODS: This was a long-term retrospective, medical record study, supplemented with a questionnaire, including 81 women. Data from the Swedish Prescribed Drug Register were used to examine adherence. The women were followed for 5 years of offered AET. RESULTS: Out of 81 women, 67 (83%) were adherent (hade taken out 80% or more of the recommended dose), 10 (12%) were Partially Adherent and 4 (5%) never accepted AET. At baseline, the Never-Adherent group members were younger, more often considered themselves healthy and seemed much more satisfied with their lives. Baseline factors that positively affected adherence were satisfaction with the vocational situation (p = 0.023) and satisfaction with family life (p = 0.040). Cumulative musculoskeletal side effects were more frequently reported among women in the Adherent group than Partially Adherent women, after both 12 and 60 months (p = 0.018 and p = 0.011, respectively). There was also a significant difference in reported cumulative psychological side effects (p = 0.049) in disfavour of the Adherent group. Moreover, according to the questionnaire where the women retrospectively were asked which side effects, they experienced during the treatment period; sexual desire was significantly lower in the Adherent group (p = 0.0402) than in the Partially Adherent group. CONCLUSION: It is important to consider a woman's life situation, to support those who otherwise would not be able to complete AET and to help all women relieve side effects during AET. It should be investigated why some women did not start the recommended therapy.

OBJECTIVES: Vasomotor symptoms induced by endocrine therapy are common in breast cancer survivors and a risk factor for therapy discontinuation and lower quality of life. The REALISE study evaluated the real-world treatment landscape in breast cancer survivors with vasomotor symptoms taking endocrine therapy, including pharmaceuticals, lifestyle changes, and over-the-counter products. STUDY DESIGN: Secondary analysis of the Adelphi Vasomotor Disease Specific Programme™, a large cross-sectional point-in-time survey and chart review conducted in the US and five European countries (February-October 2020). Oncologists provided demographic, clinical, and treatment data for adult breast cancer survivors with induced vasomotor symptoms taking endocrine therapy (tamoxifen or aromatase inhibitors); patients voluntarily completed self-report surveys on their symptom severity, concomitant sleep and/or mood symptoms, lifestyle changes, and use of over-the-counter products. MAIN OUTCOME MEASURES: Patient characteristics; vasomotor symptom severity; use of pharmaceuticals, lifestyle changes, and over-the-counter products (from pre-defined lists); lines of treatment. RESULTS: Overall, 77 oncologists reported data for 618 breast cancer survivors, of whom 183 (29.6 %) completed self-report forms. Physicians classified 420 (68.0 %) women as experiencing moderate-severe vasomotor symptoms, of whom 66.9 % were receiving treatment. In total, 15.2 % of all breast cancer survivors were prescribed systemic hormone therapy. Venlafaxine (24.7 %), citalopram (16.5 %), and paroxetine (13.6 %) were the most commonly prescribed nonhormonal medications. Lifestyle changes (77.8 %) and over-the-counter products (61.6 %) were common, especially in patients with concomitant sleep and/or mood symptoms. CONCLUSIONS: Despite contraindications, a relatively large proportion of treatment-seeking breast cancer survivors with vasomotor symptoms were prescribed systemic hormone therapy. This, combined with high patient-reported use of lifestyle changes and over-the-counter products, suggests a need for symptomatic relief and demand for new nonhormonal alternatives with established safety profiles in this population.

INTRODUCTION: Adrenocortical carcinoma (ACC) is rare and an aggressive tumour. Mitotane is the mainstay adjuvant drug in treating ACC. The study aimed to describe patients diagnosed with precocious puberty (PP) and other endocrinological complications during mitotane therapy. MATERIAL AND METHODS: This retrospective study enrolled 4 patients with ACC treated with mitotane therapy complicated by PP. We analysed clinical manifestations, radiological, histopathological findings, and hormonal results. RESULTS: The median age at the diagnosis of ACC was 1.5 years. All patients were treated with surgery and mitotane, accompanied by chemotherapy regimens in 2 cases. The median time from surgery to the initiation of mitotane therapy was 26 days. During mitotane treatment, PP was confirmed based on symptoms, and hormonal and imaging tests. In one patient, incomplete peripheral PP was followed by central PP. The median time from the therapy initiation to the first manifestations of PP was 4 months. Additionally, due to mitotane-induced adrenal insufficiency, patients required a supraphysiological dose of hydrocortisone (HC), and in one patient, mineralocorticoid (MC) replacement with fludrocortisone was necessary. In 2 patients, hypothyroidism was diagnosed. All patients presented neurological symptoms of varying expression, which were more severe in younger children. CONCLUSIONS: The side effects of using mitotane should be recognized quickly and adequately treated. In prepubertal children, PP could be a complication of therapy. The need to use supraphysiological doses of HC, sometimes with MC, should be highlighted. Some patients require levothyroxine replacement therapy. The neurotoxicity of mitotane is a significant clinical problem.

Tamoxifen, a pivotal therapy for hormone receptor-positive breast cancer, is known for its efficacy in reducing breast cancer recurrence and mortality. However, concerns about potential ocular complications, particularly maculopathy, have emerged. This study aims to investigate the risk and associated factors of diverse macular conditions in tamoxifen users, considering drug exposure, demographics, and systemic diseases. A nationwide cohort of tamoxifen users, comprised of 14,267 tamoxifen users, was analyzed using the health insurance review and assessment database in South Korea. Demographic and clinical characteristics were examined, and the cumulative incidence of macular diseases was stratified by age and cumulative tamoxifen dosage. We conducted logistic regression analysis to identify potential risk factors among clinical variables such as age, sex, indications for tamoxifen use, and systemic diseases associated with various macular conditions. Additionally, Cox proportional hazard models were used to determine the baseline clinical characteristics predictive of these macular conditions, with subsequent calculation of hazard ratios. Cumulative incidences of overall macular diseases, other maculopathy excluding common macular diseases, and macular edema were 26.4, 11.4, and 6.5%, respectively. The incidence of various macular conditions increased with age and the cumulative tamoxifen dose. Age, cumulative dose group, and liver diseases demonstrated significant associations with overall macular diseases and maculopathy excluding common macular diseases in multivariate logistic regression analyses (all P < 0.05). Furthermore, age emerged as significant predictive factors of maculopathy in Cox proportional hazard models. Tamoxifen-induced maculopathy poses a concern for prescribing physicians and ophthalmologists, and this study provides valuable insights into its risk and risk factors. This study may contribute to evidence-based guidelines for tamoxifen maculopathy screening, emphasizing the importance of considering age, cumulative dose, and liver diseases for recommendation on screening timing and frequency.

OBJECTIVE: Prostate cancer hormonal treatments (e.g. androgen deprivation therapy) yield clinical benefits. However, there is increasing evidence these treatments may adversely impact cognitive functioning. This study aimed to qualitatively characterise the nature and impact of cognitive difficulties following these treatments. METHODS: Prostate cancer survivors (PCS) self-reporting cognitive difficulties following hormonal treatments (via an online survey) and their partners were invited to participate in semi-structured interviews. Telephone or videoconferencing interviews were conducted, then transcribed, double-coded and analysed using the Framework Method, following the principles of Interpretative Phenomenological Analysis. RESULTS: Eleven participants (six PCS and five partners) were interviewed. PCS reported a range of cognitive difficulties, verified by their partners, including forgetfulness, "fogginess", fatigue and slowed processing speed. For some PCS, word-finding difficulties, tangential speech and memory problems were apparent during interviews. The aetiology of the reported cognitive difficulties was unclear as it was attributed to a possible combination of cancer treatments, compounding side-effects (e.g. fatigue, sleep problems, hot flashes), exacerbation of pre-existing conditions and/or age-related changes. Cognitive difficulties were reported to have led to shifts in self-perception, interpersonal dynamics and increased emotionality. Engagement in cognitively-stimulating activities and reliance on compensatory strategies were reported to be helpful in managing some cognitive difficulties. All participants endorsed the potential benefits of neuropsychological intervention. CONCLUSIONS: There are a diverse range of cognitive difficulties following hormonal treatments for prostate cancer experienced by PCS and their partners. Understanding the impact of these difficulties is important for the development of targeted neuropsychological interventions.

PURPOSE: Phosphatidylinositol 3-kinase/AKT-serine threonine kinase/mammalian target of rapamycin (mTOR) pathway abnormalities contribute to endocrine resistance. Everolimus, an mTOR inhibitor, improved progression-free survival in hormone receptor-positive metastatic breast cancer (BC) when combined with endocrine therapy (ET). In this phase III randomized, placebo-controlled trial, we assessed the efficacy of everolimus + ET as adjuvant therapy in high-risk, hormone receptor-positive, human epidermal growth factor receptor 2-negative BC after adjuvant/neoadjuvant chemotherapy. METHODS: Patients were randomly assigned 1:1 to physician's choice ET and 1 year of everolimus (10 mg orally once daily) or placebo stratified by risk group. The primary end point was invasive disease-free survival (IDFS) evaluated by a stratified log-rank test with the hazard ratio (HR) estimated by Cox regression. Subset analyses included preplanned evaluation by risk group and exploratory analyses by menopausal status and age. Secondary end points included overall survival (OS) and safety. Everolimus did not improve IDFS/OS when added to ET in patients with early-stage high-risk, hormone receptor-positive BC. RESULTS: One thousand and nine hundred thirty-nine patients were randomly assigned with 1,792 eligible for analysis. Overall, no benefit of everolimus was seen for IDFS (HR, 0.94 [95% CI, 0.77 to 1.14]) or OS (HR, 0.97 [95% CI, 0.75 to 1.26]). The assumption of proportional hazards was not met suggesting significant variability in the HR over time since the start of treatment. In an unplanned subgroup analysis among postmenopausal patients (N = 1,221), no difference in IDFS (HR, 1.08 [95% CI, 0.86 to 1.36]) or OS (HR, 1.19 [95% CI, 0.89 to 1.60]) was seen. In premenopausal patients (N = 571), everolimus improved both IDFS (HR, 0.64 [95% CI, 0.44 to 0.94]) and OS (HR, 0.49 [95% CI, 0.28 to 0.86]). Treatment completion rates were lower in the everolimus arm compared with placebo (48% v 73%) with higher grade 3 and 4 adverse events (35% v 7%). CONCLUSION: One year of adjuvant everolimus + ET did not improve overall outcomes. Subset analysis suggests mTOR inhibition as a possible target for patients who remain premenopausal after chemotherapy.

BACKGROUND: Hot flashes are a common side effect of endocrine therapy (ET) that contribute to poor quality of life and decreased treatment adherence. METHODS: Patients with breast cancer wo were receiving ET and experiencing hot flashes were enrolled through three parallel, randomized trials conducted in the United States, China, and South Korea. Participants were randomized to either immediate acupuncture (IA) or delayed acupuncture control (DAC). IA participants received 20 acupuncture sessions over 10 weeks, whereas DAC participants received usual care, then crossed over to acupuncture with a reduced intensity. The primary end point was a change in score on the endocrine symptom subscale of the Functional Assessment of Cancer Therapy (FACT)-Endocrine Symptoms between baseline and week 10. Secondary end points included the hot flash score and the FACT-Breast score. A planned pooled analysis of individual patient data was performed using longitudinal mixed models. RESULTS: In total, 158 women with stage 0-III breast cancer were randomized (United States, n = 78; China, n = 40; South Korea, n = 40). At week 10, IA participants reported statistically significant improvements in the endocrine symptom subscale score (mean change ± standard error: 5.1 ± 0.9 vs. 0.2 ± 1.0; p = .0003), the hot flash score (-5.3 ± 0.9 vs. -1.4 ± 0.9; p < .003), and the FACT-Breast total score (8.0 ± 1.6 vs. -0.01 ± 1.6; p = .0005) compared with DAC participants. The effect of the acupuncture intervention differed by site (p = .005). CONCLUSIONS: Acupuncture led to statistically and clinically meaningful improvements in hot flashes, endocrine symptoms, and breast cancer-specific quality of life in women undergoing ET for breast cancer in the United States, China, and South Korea.

Tamoxifen is a non-steroidal selective oestrogen receptor modulator commonly used in the treatment of breast cancer. It is associated with the development of fatty liver and steatohepatitis however drug-induced liver injury is rare. We report a woman in her 50s who developed malaise with an acute moderate aminotransferase elevation without jaundice 6 months after starting tamoxifen. She was not commenced on any other recent drugs and extensive investigation including infective and autoimmune liver screen, cross-sectional imaging and FibroScan were unremarkable. Liver biopsy revealed moderate lobular hepatitis with hepatocyte drop-out. Tamoxifen was ceased and the liver enzymes showed resolution over the following 3 months and improvement of her symptoms.

INTRODUCTION: Acromegaly is a rare endocrine disorder usually caused by a benign growth hormoneâsecreting pituitary adenoma. Surgical adenoma resection is typically the first line of treatment, and medical therapy is used for patients with persistent disease following surgery, for adenoma recurrence, or for patients ineligible for, or declining, surgery. Approved somatostatin receptor ligands (SRLs) have been limited to injectable options, until recently. Oral octreotide capsules (OOC) are the first approved oral SRL for patients with acromegaly. AREAS COVERED: We review published reports and provide case study examples demonstrating practical considerations on the use of OOC. Using two hypothetical case scenarios, we discuss current treatment patterns, breakthrough symptoms and quality of life (QoL), efficacy of SRLs, OOC dose titration, evaluation of OOC treatment response, and incidence and management of adverse events. EXPERT OPINION: OOC are an option for patients with acromegaly including those who experience breakthrough symptoms, who have preference for oral therapies, or other reasons for declining injectable SRLs. OOC have been associated with improved patient-reported QoL measures compared with those reported for lanreotide and octreotide. Continued real-world experience will determine whether OOC, alone or in combination with other therapies, provides further advantages over current injectable acromegaly treatments.

INTRODUCTION: This qualitative research study was conducted to develop a novel, comprehensive, patient-reported outcome measure (PRO), the "Symptoms and Impacts of Androgen Deprivation Therapy (ADT) for Prostate Cancer" (SIADT-PC), assessing hormonal therapy-related symptoms and their impacts on men with advanced prostate cancer. METHODS: Concept elicitation (CE) interviews were conducted among adult men with prostate cancer to evaluate their experiences with ADT. Based on key symptom and impact concepts mentioned, an initial PRO measure was developed. The draft measure was further assessed in cognitive debriefing (CD) interviews with men with prostate cancer, in which participants reviewed items, response options, and recall periods. Initial item-based psychometric analyses were conducted using interview data. The draft questionnaire was revised on the basis of participant feedback, quantitative psychometric results, and consultation with clinical experts. RESULTS: A total of 21 participants were interviewed (CE concept elicitation, n = 12; CD cognitive debriefing, n = 17; n = 8 completed both). Mean participant age (SD) was 59.7 (8.7) years and 76.2% were white. The de novo SIADT-PC measure consists of 27 items: 11 symptoms (e.g., fatigue, hot flashes, and erectile dysfunction), 2 long-term symptoms (e.g., weight gain), 10 impacts (e.g., impacts on physical activities and relationships), and 4 related to mode of administration (i.e., injection-site reactions). Items were assessed with a 5-point verbal rating scale, with answer choices that capture frequency or severity. CONCLUSIONS: Once fully validated, this de novo measure may be used in clinical studies and clinical practice to assess hormone therapy-related symptoms and impacts, enabling physicians to identify timely and appropriate interventions.

PURPOSE: The aim of this study was to quantitatively compare the efficacy and safety of CDK4/6 inhibitors and PI3K/AKT/mTOR inhibitors for ER+/HER2- metastatic breast cancer. METHODS: A parametric survival function was used to analyze the time course of overall survival (OS) and progression-free survival (PFS). The objective response rate (ORR) and the incidence of any grade and grade 3-4 adverse events were summarized using the random-effects model of a single-arm meta-analysis. RESULTS: This study included 44 arms from 48 publications, with a total sample size of 7881 patients. Our study revealed that CDK4/6 inhibitors had a median OS of 40.7 months, a median PFS of 14.8 months, and an ORR of 40%, whereas PI3K/AKT/mTOR inhibitors had a median OS of 29.8 months, a median PFS of 8.3 months, and an ORR of 20%. Additionally, this study also found that the proportion of patients with visceral metastases and specific endocrine therapy used in combination significantly impact OS and PFS. In terms of adverse events, CDK4/6 inhibitors exhibited a relatively high incidence of hematological adverse events. CONCLUSION: Our study provides solid quantitative evidence for the first-line recommendation of CDK4/6 inhibitors combined with endocrine therapy for ER+/HER2- metastatic breast cancer in clinical guidelines.

BACKGROUND: Electronic patient-reported outcomes (ePRO) monitoring is a useful communication tool for cancer patients and healthcare providers. In this study, we examined the impact of symptom monitoring using an ePRO app on quality of life (QoL) in postmenopausal breast cancer patients receiving adjuvant endocrine therapy. METHODS: The free app "Welby My Carte ONC" was used in the study. Patients with breast cancer starting adjuvant endocrine therapy were randomly assigned in a 1:1 ratio to ePRO monitoring (ONC) and control groups. The ONC group reported five symptoms extracted from the Patient-Reported Outcome-Common Terminology Criteria for Adverse Events (PRO-CTCAE) (insomnia, joint pain, headache, anxiety, and hot flashes) weekly for 3 months through the app. Reported symptoms were shared with medical personnel. When serious symptoms were reported, these personnel ascertained the patient's health status and provided advice over the phone. The primary endpoint was QoL measured by the Functional Assessment of Cancer Therapy-Breast (FACT-B) at 3 months from enrollment. Differences between groups were tested using analysis of covariance. RESULTS: The study included 125 subjects with mean age of 64 years in the ONC group (n = 61) and 63 years in the control group (n = 64). In the ONC group, the response rate to PRO-CTCAE was about 70% or higher until week 10. The item missing rate was 0. The ONC group reported more symptoms related to joint pain and insomnia. The difference in FACT-B total score between the groups was - 1.55 (95% confidence interval: - 5.91, 2.81), indicating no significant difference. CONCLUSIONS: Symptom monitoring using ePRO early after initiation of adjuvant endocrine therapy after surgery did not improve QoL of breast cancer patients.

PURPOSE: We investigated time to pregnancy, efficacy and safety of fertility preservation, and assisted reproductive technologies (ARTs) in women with early hormone receptor-positive breast cancer (BC) desiring future pregnancy. PATIENTS AND METHODS: POSITIVE is an international, single-arm, prospective trial, in which 518 women temporarily interrupted adjuvant endocrine therapy to attempt pregnancy. We evaluated menstruation recovery and factors associated with time to pregnancy and investigated if ART use was associated with achieving pregnancy. The cumulative incidence of BC-free interval (BCFI) events was estimated according to the use of ovarian stimulation at diagnosis. The median follow-up was 41 months. RESULTS: Two hundred seventy-three patients (53%) reported amenorrhea at enrollment, of whom 94% resumed menses within 12 months. Among 497 patients evaluable for pregnancy, 368 (74%) reported at least one pregnancy. Young age was the main factor associated with shorter time to pregnancy with cumulative incidences of pregnancy by 1 year of 63.5%, 54.3%, and 37.7% for patients age <35, 35-39, and 40-42 years, respectively. One hundred and seventy-nine patients (36%) had embryo/oocyte cryopreservation at diagnosis, of whom 68 reported embryo transfer after enrollment. Cryopreserved embryo transfer was the only ART associated with higher chance of pregnancy (odds ratio, 2.41 [95% CI, 1.75 to 4.95]). The cumulative incidence of BCFI events at 3 years was similar for women who underwent ovarian stimulation for cryopreservation at diagnosis, 9.7% (95% CI, 6.0 to 15.4), compared with those who did not, 8.7% (95% CI, 6.0 to 12.5). CONCLUSION: In POSITIVE, fertility preservation using ovarian stimulation was not associated with short-term detrimental impact on cancer prognosis. Pregnancy rates were highest among those who underwent embryo/oocyte cryopreservation followed by embryo transfer.
