RESUMEN

BACKGROUND: Patients with testicular cancer treated with chemotherapy have an increased risk of developing early cardiovascular events. Identification of patients with testicular cancer at a high risk of these events enables the development of preventative strategies. This study validates the vascular fingerprint tool to identify these patients. PATIENTS AND METHODS: We carried out a multicenter prospective study in patients with metastatic testicular cancer [International Germ Cell Cancer Collaborative Group (IGCCCG) good or intermediate risk; retroperitoneal mass <5 cm]. In eligible patients, the vascular fingerprint was assessed before the start of cisplatin-based chemotherapy, which consists of five risk factors, namely, smoking, overweight (body mass index >25 kg/m2), hypertension (blood pressure >140/90 mmHg), dyslipidemia (fasting cholesterol >5.1 mmol/l or low-density lipoprotein-cholesterol >2.5 mmol/l), and diabetes mellitus (fasting glucose ≥7.0 mmol/l). The presence of three or more risk factors was defined as high-risk vascular fingerprints. A log-rank test was carried out with a cardiovascular event within 1 year after the start of chemotherapy as the primary endpoint. RESULTS: A total of 196 patients with metastatic testicular cancer were included; 15 patients (8%) developed a cardiovascular event: 4 (2%) arterial events and 11 (6%) venous thrombotic events. Overall, 189 vascular fingerprint scores were available. Patients with a high-risk vascular fingerprint (62/189) had a higher risk of developing a cardiovascular event (hazard ratio 3.27, 95% confidence interval 1.16-9.18; log-rank: P = 0.017). Histological diagnosis, prognosis group, cumulative chemotherapy dose, and retroperitoneal mass size did not differ between patients with or without a cardiovascular event. All patients with an arterial event had a high-risk vascular fingerprint compared with 5/11 patients with a venous event. Overweight was more prevalent in patients with cardiovascular events (87% versus 59%; P = 0.037). CONCLUSIONS: The vascular fingerprint is a validated tool to identify patients with testicular cancer at a high risk of developing early cardiovascular events. This tool can be used to develop preventative strategies with anticoagulant treatment.

RESUMEN

BACKGROUND: Testicular cancer incidence among adolescents and young adults (AYAs, aged 18-39 years at diagnosis) is increasing worldwide and most patients will survive the initial disease. Still, detailed epidemiological information about testicular cancer among AYAs is scarce. This study aimed to provide a detailed overview of testicular cancer trends in incidence, treatment, long-term relative survival and mortality by histological subtype among AYAs diagnosed in the Netherlands between 1989 and 2019. MATERIALS AND METHODS: Data of all malignant testicular cancers (ICD-code C62) were extracted from the Netherlands Cancer Registry. Mortality data were retrieved from Statistics Netherlands. European age-standardized incidence and mortality rates with average annual percentage change statistics and relative survival estimates up to 20 years of follow-up were calculated. RESULTS: A total of 12 528 testicular cancers were diagnosed between 1989 and 2019. Comparing 1989-1999 to 2010-2019, the incidence increased from 4.4 to 11.4 for seminomas and from 5.7 to 11.1 per 100 000 person-years for non-seminomas. Rising trends were most prominent for localized disease. Radiotherapy use in localized testicular seminomas declined from 78% in 1989-1993 to 5% in 2015-2019. Meanwhile, there was a slight increase in chemotherapy use. Most AYAs with localized seminomas and non-seminomas received active surveillance only (>80%). Overall, relative survival estimates remained well above 90% even at 20 years of follow-up for both seminomas and non-seminomas. Mortality rates declined from 0.5 to 0.4 per 100 000 person-years between 1989-1999 and 2010-2019. CONCLUSIONS: The incidence of seminoma and non-seminoma testicular cancers significantly increased in AYAs in the Netherlands between 1989 and 2019. There was a shift towards less-aggressive treatment regimens without negative survival effects. Relative survival estimates remained well above 90% at 20 years of follow-up in most cases. Testicular cancer mortality was already low, but has improved further over time, which makes survivorship care an important issue for these young adults.

RESUMEN

BACKGROUND: With increasing survival rates of adolescents and young adults (AYAs) with breast cancer, health-related quality of life (HRQoL) becomes more important. An important aspect of HRQoL is sexual QoL. This study examined long-term sexual QoL of AYA breast cancer survivors, compared sexual QoL scores with that of other AYA cancer survivors, and identified factors associated with long-term sexual QoL of AYA breast cancer survivors. MATERIALS AND METHODS: Data of the SURVAYA study were utilized for secondary analyses. Sexual QoL was assessed using the European Organization for Research and Treatment of Cancer Quality of Life cancer survivorship core questionnaire (EORTC QLQ-SURV100). Descriptive statistics were used to describe sexual QoL of AYA cancer survivors. Linear regression models were constructed to examine the effect of cancer type on sexual QoL and to identify factors associated with sexual QoL. RESULTS: Of the 4010 AYA cancer survivors, 944 had breast cancer. Mean sexual QoL scores of AYA breast cancer survivors ranged from 34.5 to 60.0 for functional domains and from 25.2 to 41.5 for symptom-orientated domains. AYA breast cancer survivors reported significantly lower sexual QoL compared to AYA survivors of other cancer types on all domains. Age, time since diagnosis, relationship status, educational level, chemotherapy, hormonal therapy, breast surgery, body image, and coping were associated with sexual QoL of AYA breast cancer survivors. CONCLUSIONS: AYA breast cancer survivors experience decreased sexual QoL in the long term (5-20 years) after diagnosis and worse score compared to AYA survivors of other cancer types, indicating a clear need to invest in supportive care interventions for those at risk, to enhance sexual well-being.

RESUMEN

BACKGROUND: Despite the advent of immunotherapy in urothelial cancer, there is still a need to find effective cytotoxic agents beyond first and second lines. Vinflunine is the only treatment approved in this setting by the European Medicines Agency and taxanes are also widely used in second line. Cabazitaxel is a taxane with activity in docetaxel-refractory cancers. A randomized study was conducted to compare its efficacy versus vinflunine. PATIENTS AND METHODS: This is a multicenter, randomized, open-label, phase II/III study, following a Simon's optimal method with stopping rules based on an interim futility analysis and a formal efficacy analysis at the end of the phase II. ECOG Performance Status, anaemia and liver metastases were stratification factors. Primary objectives were overall response rate for the phase II and overall survival for the phase III. RESULTS: Seventy patients were included in the phase II across 19 institutions in Europe. Baseline characteristics were well balanced between the two arms. Three patients (13%) obtained a partial response on cabazitaxel (95% CI 2.7-32.4) and six patients (30%) in the vinflunine arm (95% CI 11.9-54.3). Median progression-free survival for cabazitaxel was 1.9 versus 2.9 months for vinflunine (P = 0.039). The study did not proceed to phase III since the futility analysis showed a lack of efficacy of cabazitaxel. A trend for overall survival benefit was found favouring vinflunine (median 7.6 versus 5.5 months). Grade 3- to 4-related adverse events were seen in 41% patients with no difference between the two arms. CONCLUSION: This phase II/III second line bladder study comparing cabazitaxel with vinflunine was closed when the phase II showed a lack of efficacy of the cabazitaxel arm. Vinflunine results were consistent with those known previously. TRIAL NUMBER: NCT01830231.

RESUMEN

The ESMO Magnitude of Clinical Benefit Scale (ESMO-MCBS) is a standardised, generic, validated tool to stratify the magnitude of clinical benefit that can be anticipated from anticancer therapies. The ESMO-MCBS is intended to both assist oncologists in explaining the likely benefits of a particular treatment to their patients as well as to aid public health decision makers' prioritise therapies for reimbursement. From its inception the ESMO-MCBS Working Group has invited questions and critiques to promote understanding and to address misunderstandings regarding the nuanced use of the scale, and to identify shortcomings in the scale to be addressed in future planned revisions and updates. The ESMO-MCBS V.1.0 has attracted many questions regarding its development, structure and potential applications. These questions, together with responses from the ESMO-MCBS Working Group, have been edited and collated, and are herein presented as a supplementary resource.

RESUMEN

Non-specialized centres see relatively few patients with rare cancers like soft tissue sarcoma. This leads to inappropriate diagnostic work-up and treatment resulting in a worse oncological outcome. We believe that modern tailor-made therapy for rare cancers requires not only the multidisciplinary expertise of specialized cancer centres but also, occasionally, the expert knowledge of an international network of specialist centres. Here, we emphasize the importance of national and international networks for the treatment of patients with rare tumours. The importance is placed in perspective using the treatment of sarcoma patients as an example.

RESUMEN

The value of any new therapeutic strategy or treatment is determined by the magnitude of its clinical benefit balanced against its cost. Evidence for clinical benefit from new treatment options is derived from clinical research, in particular phase III randomised trials, which generate unbiased data regarding the efficacy, benefit and safety of new therapeutic approaches. To date, there is no standard tool for grading the magnitude of clinical benefit of cancer therapies, which may range from trivial (median progression-free survival advantage of only a few weeks) to substantial (improved long-term survival). Indeed, in the absence of a standardised approach for grading the magnitude of clinical benefit, conclusions and recommendations derived from studies are often hotly disputed and very modest incremental advances have often been presented, discussed and promoted as major advances or 'breakthroughs'. Recognising the importance of presenting clear and unbiased statements regarding the magnitude of the clinical benefit from new therapeutic approaches derived from high-quality clinical trials, the European Society for Medical Oncology (ESMO) has developed a validated and reproducible tool to assess the magnitude of clinical benefit for cancer medicines, the ESMO Magnitude of Clinical Benefit Scale (ESMO-MCBS). This tool uses a rational, structured and consistent approach to derive a relative ranking of the magnitude of clinically meaningful benefit that can be expected from a new anti-cancer treatment. The ESMO-MCBS is an important first step to the critical public policy issue of value in cancer care, helping to frame the appropriate use of limited public and personal resources to deliver cost-effective and affordable cancer care. The ESMO-MCBS will be a dynamic tool and its criteria will be revised on a regular basis.

RESUMEN

PURPOSE: To evaluate whether trabectedin as first-line chemotherapy for advanced/metastatic soft tissue sarcoma prolongs progression-free survival (PFS), compared to doxorubicin and, in the phase IIb part here, to select the most appropriate trabectedin treatment schedule (3-hour or 24-hour infusion) in terms of safety, convenience and efficacy. PATIENTS AND METHODS: In this randomised multicentre prospective dose-selection phase IIb superiority trial, 133 patients were randomised between doxorubicin (n=43), trabectedin (3-hour infusion, T3h) (n=47) and trabectedin (24-hour infusion, T24h) (n=43). PFS was defined as time from random assignment until objective progression by response evaluation criteria in solid tumours (RECIST 1.1), a global deterioration of the health status requiring discontinuation of the treatment, or death from any cause. RESULTS: The study was terminated due to lack of superiority in both trabectedin treatment arms as compared to the doxorubicin control arm. Median PFS was 2.8months in the T3h arm, 3.1months in the T24h arm and 5.5months in the doxorubicin arm. No significant improvements in PFS were observed in the trabectedin arms as compared to the doxorubicin arm (T24h versus doxorubicin: hazard ratio (HR) 1.13, 95% confidence interval (CI) 0.67-1.90, P=.675; T3h versus doxorubicin: HR 1.50, 95% CI 0.91-2.48, P=.944). Only one toxic death occurred in the T3h arm, but treatment had to be stopped due to toxicity in 7 (15.2%) (T3h), 8 (19.5%) (T24h) and 1 (2.5%) doxorubicin patients. CONCLUSION: Doxorubicin continues to be the standard treatment in eligible patients with advanced/metastatic soft-tissue sarcoma (STS). Trabectedin 1.5mg/m(2)/24-hour infusion is the overall proven approach to delivering this agent in the second-line setting for patients with advanced or metastatic STS.

RESUMEN

BACKGROUND: Pazopanib recently received approval for the treatment of certain soft tissue sarcoma (STS) subtypes. We conducted a retrospective analysis on pooled data from two EORTC trials on pazopanib in STS in order to characterize long-term responders and survivors. PATIENTS AND METHODS: Selected patients were treated with pazopanib in phase II (n = 118) and phase III study (PALETTE) (n = 226). Combined median progression-free survival (PFS) was 4.4 months; the median overall survival (OS) was 11.7 months. Thirty-six percent of patients had a PFS ≥ 6 months and were defined as long-term responders; 34% of patients survived ≥18 months, defined as long-term survivors. Patient characteristics were studied for their association with long-term outcomes. RESULTS: The median follow-up was 2.3 years. Patient characteristics were compared among four subgroups based on short-/long-term PFS and OS, respectively. Seventy-six patients (22.1%) were both long-term responders and long-term survivors. The analysis confirmed the importance of known prognostic factors in metastatic STS patients treated with systemic treatment, such as performance status and tumor grading, and additionally hemoglobin at baseline as new prognostic factor. We identified 12 patients (3.5%) remaining on pazopanib for more than 2 years: nine aged younger than 50 years, nine females, four with smooth muscle tumors and nine with low or intermediate grade tumors at initial diagnosis. The median time on pazopanib in these patients was 2.4 years with the longest duration of 3.7 years. CONCLUSIONS: Thirty-six percent and 34% of all STS patients who received pazopanib in these studies had a long PFS and/or OS, respectively. For more than 2 years, 3.5% of patients remained progression free under pazopanib. Good performance status, low/intermediate grade of the primary tumor and a normal hemoglobin level at baseline were advantageous for long-term outcome. NCT00297258 (phase II) and NCT00753688 (phase III, PALETTE).

RESUMEN

AIM: Brostallicin is a DNA minor groove binder that has shown activity in patients with soft tissue sarcoma (STS) failing first-line therapy. The present study assessed the safety and efficacy of first-line brostallicin in patients with advanced or metastatic STS >60 years or not fit enough to receive combination chemotherapy. A prospective explorative pharmacogenetic analysis was undertaken in parallel. METHODS: Patients were randomised in a 2:1 ratio between IV brostallicin 10mg/m(2) and doxorubicin 75 mg/m(2) once every 3 weeks for a maximum of six cycles. Disease stabilisation at 26 weeks (primary end-point) was considered a 'success'. Further testing of brostallicin was warranted if ≥ 35 'successes' were observed in the first 72 eligible patients treated with brostallicin. In addition, patients were genotyped for glutathione S transferase (GST) polymorphisms. RESULTS: One hundred and eighteen patients were included (79 brostallicin and 39 doxorubicin). Brostallicin was well tolerated in comparison to doxorubicin with less grade 3-4 neutropenia (67% versus 95%), grade 2-3 systolic dysfunction (0% versus 11%), alopecia (17% versus 61%) and grade 2-3 mucositis (0% versus 18%). For brostallicin versus doxorubicin, 'successes' were observed in 5/77 versus 10/36, progression free survival at 1 year was 6.5% versus 15.6%, objective response rate was 3.9% versus 22.2% and overall survival at 1 year was 50.5% versus 57.9%, respectively. Only GSTA1 genotype was significantly associated with success rate of doxorubicin treatment. CONCLUSION: Brostallicin cannot be recommended at this dose and schedule in this patient population as first-line therapy. GSTA1 genotype may be predictive for doxorubicin efficacy but warrants further study.

RESUMEN

AIM: To evaluate the outcome of patients with locally advanced muscle-invasive and/or lymph node positive bladder cancer treated with induction chemotherapy and additional surgery. METHODS: All patients who were treated with induction chemotherapy in our institution between 1990 and 2010, were retrospectively evaluated using an institutional database. Induction chemotherapy consisted of methotrexate, vinblastine, doxorubicin and cisplatin (MVAC), or a combination of gemcitabine with either cisplatin or carboplatin (GC). RESULTS: In total 152 patients were identified, with a mean age of 59 years (range 31-76). One hundred and seven patients (70.4%) received MVAC, 35 patients received GC (23.0%) and 10 patients received GC after initial treatment with MVAC (6.6%). Median follow-up was 68 months (range 4-187 months). Overall 125 patients (82.2%) underwent cystectomy, whereas 12 patients (7.9%) received radiotherapy. Fifteen patients had no local treatment. Median overall survival was 18 months (95%CI 15-23 months). In 37.5% of patients with complete clinical response, residual disease was found at surgery (positive predictive value, PPV 62.5%). Complete pathological response was seen in 26.3% of patients, with a 5 year overall survival (OS) estimate of 54% (39%-74%). For patients with persisting node positive disease after induction chemotherapy and surgery OS was significantly worse (p < 0.0001). CONCLUSIONS: Complete clinical and/or pathological response to induction chemotherapy results in a significant survival benefit. The accuracy of the current clinical response evaluation after induction chemotherapy is limited. Although surgery may be important for staging and prognostic purposes, its role is unclear in node positive disease after induction chemotherapy.

RESUMEN

BACKGROUND: The incidence of symptomatic brain metastases in small-cell carcinoma of the urinary bladder (SCBC) is unknown. This precludes advice about prophylactic cranial irradiation (PCI). PATIENTS AND METHODS: The medical records of all patients with SCBC seen at The Netherlands Cancer Institute from 1993 to 2009 (n = 51) were reviewed. Limited disease (LD) was defined as any pT, cN0₋1, and cM1. Patients with LD were offered bladder-preserving treatment involving combined chemoradiotherapy. Patients with extensive disease (ED) were treated with palliative chemotherapy. PCI was not applied in any patient. RESULTS: Among 39 patients with LD, median disease-specific survival was 35 months. Four developed symptomatic brain metastases after a median follow-up of 15 months (range 3-24) and were treated with whole-brain radiotherapy. No patient with ED developed symptomatic brain metastases during a median follow-up of 6 months. The reported incidence of brain metastases in SCBC in the literature ranges between 0% and 40%. On the basis of all reported series, the pooled estimate of the cumulative incidence of brain metastases is 10.5% (95% confidence interval 7.5% to 14.1%). CONCLUSIONS: The incidence of symptomatic brain metastases from SCBC is significantly lower than that from small-cell lung cancer. Therefore, we do not routinely advise PCI in patients with SCBC.

RESUMEN

BACKGROUND: The aim of this study is to determine efficacy and feasibility of the combination regimen irinotecan and cisplatin in patients with cisplatin advanced penile cancer. PATIENTS AND METHODS: Patients with T3, T4, N1, N2, N3 or M1 cisplatin advanced penile cancer were treated with a combination of irinotecan (60 mg/m(2)) on days 1, 8 and 15 and cisplatin (80 mg/m(2)) administered every 28 days. Patients were treated either in the neo-adjuvant setting for T3 or N1-N2 disease with a maximum of four cycles before surgery or up to eight cycles for T4 or N3 or M1 disease. The study was designed with the aim to exclude a response rate (complete response + partial response) <30% (alpha = 10%, power = 95%). RESULTS: Twenty-eight patients were included and evaluated for toxicity, and 26 eligible patients were evaluated for response. Toxicity was acceptable with three cases of grade 3 diarrhoea and two cases of grade 4 neutropenic fever. There were eight responses (two complete response and six partial response) (30.8%, 80% confidence interval 18.8% to 45.1%): three patients undergoing histological verification after chemotherapy had no evidence of malignancy. CONCLUSION: The study fails to demonstrate a response rate significantly >30%. The observation regarding M0 patients suggests to repeat this study in the neo-adjuvant setting.

RESUMEN

Muscle-invasive bladder cancer is an important oncological problem. When no distant metastases are detected, a radical cystectomy is the standard treatment. In recent years new developments in the treatment of the disease have been explored. These developments comprise new surgical techniques such as neobladder construction using the patient's intestinal tissue, sexuality-preserving surgery and robot-assisted surgery. Furthermore, indications for perioperative chemotherapy are discussed. Finally, bladder-sparing approaches are described: brachytherapy and chemo-radiation.

RESUMEN

PURPOSE: We gained insight into the effect of neoadjuvant chemotherapy and subsequent surgery in patients with bladder cancer with tumor positive lymph nodes. MATERIALS AND METHODS: A total of 52 patients with histologically proven positive lymph nodes (by lymph node dissection or aspiration cytology) were treated with chemotherapy and post-chemotherapy surgery in case of partial or complete response. We evaluated response in the primary tumor and lymph nodes, long-term clinical outcome, and clinicopathological features potentially predictive of survival. RESULTS: Complete response, partial response and stable/progressive disease were attained in 29%, 57% and 14%, and resulted in a 5-year survival of 42%, 19% and 0%, respectively. Objective response (HR 4.1), especially complete response (HR 8.0), was independently associated with survival. The prognostic values of lymph node status and bladder tumor status after methotrexate, vinblastine, doxorubicin and cisplatin were evaluated separately. A tumor negative bladder combined with tumor negative nodes were associated with improved survival (HR 4.4) as was a tumor negative lymph node region in the presence of residual bladder disease (HR 2.8). All patients with post-chemotherapy tumor positive nodes died within 2 years. In resected specimens residual disease was found in 4 of 15 clinically complete responders while no tumor could be detected in 3 of 29 clinically assessed as partial responders. CONCLUSIONS: Response to chemotherapy is associated with improved survival, and our data suggest that lymph node status after methotrexate, vinblastine, doxorubicin and cisplatin is more important than local tumor status in this aspect. In the absence of reliable noninvasive methods, post-chemotherapy surgery in this series was the most adequate method of response evaluation and in limited partial responders led to long-term progression-free survival.

RESUMEN

Metastatic renal cell cancer is one of the immuno-sensitive tumors. Apart from the immuno-modulating agents IFNalpha and IL-2, thalidomide has been reported to be effective in this type of cancer. However, bone metastases and bulky metastases, show limited response to immunotherapy, are often site of recurrent disease and are therefore often treated later with radiotherapy. In this phase II study, we evaluated toxicity and efficacy of the combination of continuous low dose (1 mIU/m2) s.c. IL-2 and thalidomide (200 mg once daily) in 22 patients with progressive metastatic renal cell cancer. In addition, 13 soft tissue lesions and two bone metastases in 13 patients were concurrently treated with fractionated radiotherapy. T cell number and activation in blood was measured by immunoflowcytometry. Nearly all patients developed grade 1-2 toxicity consisting of fatigue, sensory neuropathy, constipation and dizziness. Five patients had a grade 3-4 toxic event: four patients with deep venous thrombosis requiring anticoagulant therapy, and one patient who developed radiation myelopathy. On systemic response evaluation ten patients showed ongoing SD with a mean progression free survival of 9 months. One patient showed a PR (at an irradiated site). Regarding local response to irradiation, seven lesions showed a PR for a mean time period of 8.7 months, whereas seven were stable for 6 months. The radiation response of one lesion was not evaluable. Immunoflowcytometry showed an increase in number and activation of lymphocytes (mainly Natural Killer--NK-cells), which was absent or even decreased in irradiated patients. The combination of sc. low dose IL-2, thalidomide and radiotherapy is feasible, but relatively toxic and does not lead to higher responses at non-irradiated sites. The combination of immunotherapy and concurrent radiotherapy is effective at 60% of the relatively large evaluable sites. Progressive myelopathy developed in one patient, possibly due to radiotherapy in combination with thalidomide.
