RESUMO
Endometrial cancer (EC) is a heterogeneous disease with a rising incidence worldwide. The understanding of its molecular pathways has evolved substantially since The Cancer Genome Atlas (TCGA) stratified endometrial cancer into four subgroups regarding molecular features: POLE ultra-mutated, microsatellite instability (MSI) hypermutated, copy-number high with TP53 mutations, and copy-number low with microsatellite stability, also known as nonspecific molecular subtype (NSMP). More recently, the International Federation of Gynecology and Obstetrics (FIGO) updated their staging classification to include information about POLE mutation and p53 status, as the prognosis differs according to these characteristics. Other biomarkers are being identified and their prognostic and predictive role in response to therapies are being evaluated. However, the incorporation of molecular aspects into treatment decision-making is challenging. This review explores the available data and future directions on tailoring treatment based on molecular subtypes, alongside the challenges associated with their testing.

Objective: Fertility preservation is a priority in oncology for female cancer patients. However, there is a lack of communication between infertility specialists and oncologists. This study aimed to evaluate infertility specialists' perceptions and experiences regarding fertility preservation. Methods: Conduct an online survey to profile infertility specialists. Participants were infertility affiliated with the Brazilian Federation of Gynecology and Obstetrics Associations (FEBRASGO). The specialists received an online survey, which response rate were 30.9%, most of whom were in southern and southeastern. The survey consisted on 14 questions about the infertility specialists' location, techniques in clinical practice, treatment successful rate, patients idea, etc. Results: The average experience in human reproduction were 15.5 ± 10.2 years (mean ± standard deviation, range 1-40). Among reproductive-aged female cancer patients recommended for fertility preservation, 60.3 ± 28.8% (range 10-100%) underwent preservation procedures. Main barriers were cost (41%), oncologists' knowledge or acceptance (35%) and accessibility (9%). Most infertility specialists (58%) considered 40 years the limit for fertility preservation. Leukemia, lymphoma, breast and ovarian cancers were prioritized for fertility preservation, while lung, thyroid, gastric, and brain cancers were less relevant. Conclusion: This is the first Brazilian study about infertility specialists' perceptions on oncology patients access to fertility preservation. These patients primarily receive treatment in the public health system, while infertility specialists mainly work in the private healthcare. This healthcare mode is currently fragmented, but integrating these experts is enhancing patient access to fertility preservation. Studies on this topic are still warranted.

Molecular characterization of endometrial cancer is allowing for increased understanding of the natural history of tumors and paving a more solid pathway for novel therapies. It is becoming increasingly apparent that molecular classification is superior to histological classification in terms of reproducibility and prognostic discrimination. In particular, the Proactive Molecular Risk Classifier for Endometrial Cancer allows classification of endometrial cancer into groups very close to those determined by the Cancer Genome Atlas Research Network-that is, DNA polymerase epsilon-mutated, mismatch repair-deficient, p53 abnormal, and non-specific molecular profile tumors. The transition from the chemotherapy era to the age of targeted agents and immunotherapy, which started later in endometrial cancer than in many other tumor types, requires widespread availability of specialized pathology and access to novel agents. Likewise, surgical expertise and state-of-the-art radiotherapy modalities are required to ensure adequate care. Nevertheless, Latin American countries still face considerable barriers to implementation of international guidelines. As we witness the dawn of precision medicine as applied to endometrial cancer, we must make continued efforts towards improving the quality of care in this region. The current article discusses some of these challenges and possible solutions.

BACKGROUND: There is no updated national data regarding the real impact of the COVID-19 pandemic on delaying diagnosis and treatment among patients with lung, and head, and neck cancers in Brazil. This study aimed to analyze the COVID-19 pandemic impact on cancer diagnosis and clinical outcomes among lung, head, and neck cancer patients assisted in a tertiary cancer center in Southeastern Brazil, as well as to analyze these patients' pretreatment clinical features. METHODS: Retrospective cohort of patients with lung or head and neck cancer assisted in a tertiary cancer center in southeastern Brazil between January/2019 and December/2021. To assess statistical differences among groups [i.e., cohort 2019 versus (vs.) 2020 and 2019 vs. 2021] chi-square test was used with a 5% significance level and 90% power for sample size calculation. Differences among baseline clinical features and sociodemographic characteristics were evaluated either by T-test for two samples or Fisher's or Pearson's chi-square test (for quantitative or qualitative variables). All utilized tests had a 5% significance level. RESULTS: Six hundred fifty-two patients were included, 332 with lung and 320 with head and neck cancer; it was observed a significant decrease in oncologic treatment recommendations and increase in palliative care recommendation for patients with lung cancer, despite similar stages at diagnosis. During the COVID-19 pandemic, more pain symptoms were reported at the first Oncology assessment for patients with head and neck cancer (p < 0.05). Compared to 2019, head and neck cancer patients diagnosed in 2021 presented a worse initial performance status (p = 0.008). There was a statistically significant increase in survival for patients diagnosed with head and neck cancer in 2021 when compared to 2019 (p = 0.003). CONCLUSIONS: This research highlights low survival rates for patients with lung and head and neck cancer in Brazil, even before the pandemic started, as consequence of advanced diseases at diagnosis at the public health system and clinical degrading features. Additionally, there was an increase incidence in both lung cancer and head and neck cancer despite no differences in clinical stage. This reflects how fragile is the public healthcare system even before facing an acute public health crisis such as the COVID-19 pandemic. Yet, the total impact on public health may follow for many years.

RESUMO
PURPOSE: This study aimed to describe the demographic and clinical characteristics of cancer patients with COVID-19, exploring factors associated with adverse outcomes. PATIENTS AND METHODS: This retrospective cohort study methodically extracted and curated data from electronic medical records (EMRs) of numerous healthcare institutions on cancer patients diagnosed with a confirmed SARS-CoV-2 infection between May 2020 and August 2021, to identify risk factors linked to extended hospitalization and mortality. The retrieved information encompassed the patients' demographic and clinical characteristics, including the incidence of prolonged hospitalization, acute complications, and COVID-19-related mortality. RESULTS: A total of 1446 cancer patients with COVID-19 were identified (mean [Standard deviation] age, 59.2 [14.3] years). Most patients were female (913 [63.1%]), non-white (646 [44.7%]), with non-metastatic (818 [56.6%]) solid tumors (1318 [91.1%]), and undergoing chemotherapy (647 [44.7%]). The rate of extended hospitalization due to COVID-19 was 46% (n = 665), which was significantly impacted by age (p = 0.012), sex (p = 0.003), race and ethnicity (p = 0.049), the presence of two or more comorbidities (p = 0.006), hematologic malignancies (p = 0.013), metastatic disease (p = 0.002), and a performance status ≥ 2 (p = 0.001). The COVID-19-related mortality rate was 18.9% (n = 273), and metastatic disease (<0.001), performance status ≥2 (<0.001), extended hospitalization (p = 0.028), renal failure (p = 0.029), respiratory failure (p < 0.001), sepsis (p = 0.004), and shock (p = 0.040) significantly and negatively influenced survival. CONCLUSION: The rate of extended hospitalization and COVID-19-specific death in cancer patients was notably high and could be influenced by comorbidities, cancer treatment status, and clinical fragility. These observations may aid in developing risk counseling strategies regarding COVID-19 in individuals diagnosed with cancer.

PURPOSE: The global burden of cancer in adolescents and young adults (AYAs) emerges as a major public health issue, in which remarkable challenges and unmet needs are evident. Because of sociodemographic inequalities, initiatives to change this scenario need to be expanded globally, particularly to low-middle-income countries (LMICs). This study aimed to gain information about the standards of AYA cancer care in Brazil from the physician's perspective. METHODS: Physicians involved in AYA cancer care were invited to answer a national online survey. The questions covered several aspects from health care's demographics to specialized services availability, such as fertility and genetic counseling. The availability of a specialized AYA cancer care facility was the primary study end point, and the findings were stratified by region and treatment setting (public v private). RESULTS: Among the physicians who responded (N = 249), 90% reported no access to a specialized AYA service. Only 20% had access to a fertility specialist, and 30% to a survivorship program in their institutions. Even external referrals to medical specialties were challenging, with 24% of the physicians reporting challenges. Despite the potential cardiotoxicity related to treatments, 43% of the respondents reported to refer patients for cardio-oncologists hardly ever. Furthermore, 36% of physicians had never enrolled AYA patients into clinical trials and 42% had never ordered a genetic test. Lack of specialized human resources was particularly evident in Northern Brazil, and delays in cancer diagnoses were frequent. CONCLUSION: This first study addresses standards of AYA cancer care across Brazil. Importantly, the data disclose significant infrastructural gaps, implying that major investments in training and infrastructure are urgently needed. These data may mirror other LMICs reality.

OBJECTIVE: Cancer imposes a profound burden on low- and middle-income countries where 65% of the global cancer deaths occurred in 2020. The objective of the present review was to describe female cancer epidemiology in Brazil, barriers to prevention, screening, and treatment, and to propose strategies to a better control. METHODS: For the process of literature search and scientific acquisition, we have utilized the terms "female cancer" AND "breast cancer," AND "cervical cancer" AND "endometrial cancer" AND "ovarian cancer" AND "Brazil" in PubMed. References of the articles included in this review were manually searched in order to identify relevant studies on the topic. The official Brazilian epidemiology data were extensively analyzed at the governmental site www.inca.gov.br. RESULTS: Considering cases of breast and gynecologic cancers together, 105,770 new cases are expected to be diagnosed yearly, positioning female cancer as the highest cancer incidence in Brazil. Female breast cancer is the most common and the leading cause of death from cancer in the female population in all regions of Brazil, except in the North, where cervical cancer ranks first. Cervical cancer, a preventable disease, corresponds to the third-most common neoplasia in women, with higher incidences in the North and Northeast regions of Brazil. An upward trend has been observed in endometrial cancer incidence, a tendency that follows the increase of its two most common risk factors: population aging and obesity. Ovarian cancer currently occupies the eighth position among female cancers in Brazil, but it is the most lethal gynecologic cancer. The main strategies to reduce female cancer mortality rates are the reduction of inequalities in healthcare services and the early diagnosis of cases. The lack of a specific national cancer program results in a reactive and unplanned approach to healthcare provision, ultimately leading to suboptimal resource utilization and higher expenditure. CONCLUSION: Analyzed together, breast and gynecologic cancers correspond to the leading cause of cancer in Brazil. A heterogeneous group, female cancer includes diseases with a high primary and secondary prevention potential. The organization of a female cancer program in Brazil prioritizing primary and secondary prevention strategies, such as adequate mammography screening and human papillomavirus vaccination coverage, could significantly improve female cancer control in the country.

Background: Endometrial cancer is of increasing concern in several countries, including Brazil, in part because of an ageing population, declines in fertility, and the increasing prevalence of obesity. Although endometrial tumors had lagged behind other cancer types in terms of treatment improvements, molecular characterization of these tumors is paving the way for novel therapies and an expansion of the therapeutic arsenal. We aimed to help medical oncologists who manage patients with recurrent or metastatic endometrial cancer in the Brazilian healthcare setting. Methods: The panel, composed of 20 medical oncologists, convened in November 2021 to address 50 multiple-choice questions on molecular testing and treatment choices. We classified the level of agreement among panelists as (1) consensus (≥75% choosing the same answer), (2) majority vote (50% to <75%), or (3) less than majority vote (<50%). Results: Consensus was present for 25 of the 50 questions, whereas majority vote was present for an additional 23 questions. Key recommendations include molecular testing for every patient with recurrent/metastatic endometrial cancer; choice of first-line treatment according to microsatellite instability and HER2, with the addition of programmed death ligand 1 (PD-L1) and hormone receptors (HRs) for second-line therapy; carboplatin and paclitaxel as the preferred option in first-line treatment of HER2-negative disease, with the addition of trastuzumab in HER2-positive disease; pembrolizumab plus lenvatinib as a key option in second line, regardless of HER2, PD-L1 or HRs; and various recommendations regarding treatment choice for patients with distinct comorbidities. Conclusion: Despite the existing gaps in the current literature, the vast majority of issues addressed by the panel provided a level of agreement sufficient to inform clinical practice in Brazil and in other countries with similar healthcare environments.
RESUMO
PURPOSE: Patient navigation (PN) is a community-based service delivery intervention designed to promote access to timely diagnosis and treatment of cancer and other chronic diseases by eliminating barriers to integral care. Considering the complex difficulties in accessing treatment and the positive results of PN in high-income countries, our group decided to evaluate this tool to improve radiotherapy (RT) access in the public system in Brazil. PATIENTS AND METHODS: This pilot study took place in a public school hospital, with a historical cohort as the control arm. The primary endpoint was the time from histologic diagnosis and RT initiation among cancer patients receiving RT with curative intent in a PN program. The secondary objectives were the following time frames: referral to the first consultation by the RT team; first consultation up to RT beginning; RT beginning to RT end; referral to the end of RT and identifying/describing obstacles to the treatment; and assessing patient satisfaction with PN program. RESULTS: A total of 124 patients were included in the retrospective arm and 73 in the navigation arm. Most had the loco-regionally advanced disease from the esophagus, head/neck, and rectum. PN decreased the median time from the biopsy result to the beginning of RT from 108 to 74 days (p < 0.001). PN reduced the time between biopsy results and referral to RT (53 to 40.5 days, p = 0.011), between the referral and the first consultation in the RT (25 to 13 days, p < 0.001), and between the referral to the end of the RT (98 to 78 days, p < 0.003). CONCLUSIONS: Proper identification of barriers, especially in a low-resource setting, is mandatory to guide PN programs in LMICs. In an oncological context of socioeconomic vulnerability, PN is a financially viable and efficient tool to optimize access to timely RT.

RESUMO
Cervical cancer remains a leading cause of morbidity and mortality amongst females in Latin America (LATAM). Cervical cancer is a preventable disease and HPV vaccination is a main key strategy towards its elimination. This study analyzes HPV vaccine implementation current status and the main barriers to achieve adequate coverage in the region. Data from the nineteen sovereign states of LATAM (comprised of all Portuguese and Spanish-speaking nations located south of the United States) were collected, including year of HPV vaccine implementation, gender and age targets, the number of doses included in the public program and coverage by dose. Sixteen out of the 19 evaluated countries have already implemented HPV vaccination programs. However, despite its proven efficacy and safety, HPV vaccine uptake in LATAM has been lower than expected. There is an evident decline in adhesion, mainly regarding the second dose. Several reasons are probably involved, of note: limited knowledge of HPV and HPV vaccine, misguided safety concerns, high cost, cultural barriers, and the Covid19 pandemic. Proper strategies to overcome these barriers are needed to ensure successful uptake. Effective policies are: adopting the one dose schedule, delivering the vaccine on both health center and schools, and advising health professionals to recommend the vaccine. Further research regarding HPV vaccine hesitancy in Latin America is needed.
RESUMO
Introduction: Due to scant literature and the absence of high-level evidence, the treatment of vulvar cancer is even more challenging in countries facing limited resources, where direct application of international guidelines is difficult. Recommendations from a panel of experts convened to address some of these challenges were developed. Methods: The panel met in Rio de Janeiro in September 2019 during the International Gynecological Cancer Society congress and was composed of specialists from countries in Africa, Asia, Eastern Europe, Latin America, and the Middle East. The panel addressed 62 questions and provided recommendations for the management of early, locally advanced, recurrent, and/or metastatic vulvar cancer. Consensus was defined as at least 75% of the voting members selecting a particular recommendation, whereas a majority vote was considered when one option garnered between 50.0% and 74.9% of votes. Resource limitation was defined as any issues limiting access to qualified surgeons, contemporary imaging or radiation-oncology techniques, antineoplastic drugs, or funding for the provision of contemporary medical care. Results: Consensus was reached for nine of 62 (14.5%) questions presented to the panel, whereas a majority vote was reached for 29 (46.7%) additional questions. For the remaining questions, there was considerable heterogeneity in the recommendations. Conclusion: The development of guidelines focusing on areas of the world facing more severe resource limitations may improve medical practice and patient care.
RESUMO
Introduction: Nearly 85% of cervical cancer new cases are diagnosed in limited resources countries. Although several strategies have been proposed to reduce the disease burden, challenges remain to provide the best possible care. We report recommendations from an expert consensus meeting convened to address from prevention to management of cervical cancer in limited resources countries. Methods: The expert panel, composed by invited specialists from 38 developing countries in Africa, Asia, Eastern Europe, Latin America, and the Middle East, convened in Rio de Janeiro in September 2019, during the Global Meeting of the International Gynecological Cancer Society (IGCS). Panel members considered the published scientific evidence and their practical experience on the topics, as well as the perceived cost-effectiveness of, and access to, the available interventions. The focus of the recommendations was on geographic regions rather than entire countries because medical practice varies considerably in the countries represented. Resource limitation was qualified as limited access to qualified surgeons, contemporary imaging or radiation-oncology techniques, antineoplastic drugs, or overall funding for provision of state-of-the-art care. Consensus was defined as at least 75% of the voting members selecting a particular answer of the multiple-choice questionnaire, whereas the majority vote was considered as 50% to 74.9%. Results: Consensus was reached for 25 of the 121 (20.7%) questions, whereas for 54 (44.6%) questions there was one option garnering between 50% to 74.9% of votes (majority votes). For the remaining questions, considerable heterogeneity in responses was observed. Discussion: The implementation of international guidelines is challenging in countries with resource limitations or unique health-care landscapes. The development of guidelines by the health care providers in those regions is more reflective of the reality on the ground and may improve medical practice and patient care. However, challenges remain toward achieving that goal at political, economic, social, and medical levels.
RESUMO
Little is known about soft tissue sarcomas (STS) in Brazil, once the federal statistics regarding estimates on incidence and mortality of the most common cancers that affect the Brazilian population currently do not include STS. This study aims to perform a broad evaluation and description of the epidemiological profile, access to treatment and main clinical outcomes of the Brazilian STS patient. A population-based cohort study of 66,825 patients who underwent procedures related to STS treatment registered in the Brazilian public health system (Sistema Único de Saúde, SUS) databases. Median age was 57 years, 30% of them older than 65 years and 50.7% of the cohort was female. The majority, 50,383 patients (75.4%), was diagnosed between 2008 and 2015. Most prevalent anatomic sites were upper and lower limbs (12.6%) and the registry of sarcomas without a specific location comprehended 29.7% of the cohort. The majority of patients resided in the Northeast (40.2% of the patients). Surgery was the first treatment modality in 77.7% of the cases. For survival analysis, only patients with stage and histological grade information were included. The 1-, 5- and 10-year survival rate of the patients was, respectively, 75.4% (95% CI = 74.1-76.7%), 43.4% (95% CI = 41.5-45.5%) and 18.6% (95% CI = 14.8-23.3%).

OBJECTIVE: This article aims to alert health professionals for cancer screening in the face of the possibility of new waves of disease. METHODS: A narrative review was conducted through a search in MEDLINE, Lilacs, Chinese Biomedical Literature Database, and international medical societies publications. RESULTS: Breast cancer: in high-risk patients (confirmed familial cancer syndrome or with high-risk tools scores), clinicians should act according to usual recommendations; in average-risk individuals, consider screening with mammography with a longer time span (maximum of two years). Cervical cancer: women turning 25 years old who have already been immunized and with no previous Pap test can have the test postponed during the pandemic; if there is no previous dose of Human Papillomavirus vaccination, initiation of screening should be recommended following a more rigid approach for COVID prevention; in women over 30 years of age who have never participated in cervical screening, the first screening exam is also essential. Colorectal cancer: if the individual is at elevated risk for familial cancer, the screening with colonoscopy according to usual recommendations should be supported; if at average risk consider screening with Fecal Occult Blood Test. Prostate cancer: there is a trend to postpone routine prostate cancer screening until the pandemic subsides. CONCLUSIONS: The decision to keep cancer screening must be discussed and individualized, considering the possibility of new waves of COVID-19.

PURPOSE: COVID-19 has affected cancer care worldwide. Clinical trials are an important alternative for the treatment of oncologic patients, especially in Latin America, where trials can be the only opportunity for some of them to access novel and, sometimes, standard treatments. METHODS: This was a cross-sectional study, in which a 22-question survey regarding the impact of the COVID-19 pandemic on oncology clinical trials was sent to 350 representatives of research programs in selected Latin American institutions, members of the Latin American Cooperative Oncology Group. RESULTS: There were 90 research centers participating in the survey, with 70 of them from Brazil. The majority were partly private or fully private (n = 77; 85.6%) and had confirmed COVID-19 cases at the institution (n = 57; 63.3%). Accruals were suspended at least for some studies in 80% (n = 72) of the responses, mostly because of sponsors' decision. Clinical trials' routine was affected by medical visits cancelation, reduction of patients' attendance, reduction of other specialties' availability, and/or alterations on follow-up processes. Formal COVID-19 mitigation policies were adopted in 96.7% of the centers, including remote monitoring and remote site initiation visits, telemedicine visits, reduction of research team workdays or home office, special consent procedures, shipment of oral drugs directly to patients' home, and increase in outpatient diagnostic studies. Importantly, some of these changes were suggested to be part of future oncology clinical trials' routine, particularly the ones regarding remote methods, such as telemedicine. CONCLUSION: To our knowledge, this was the first survey to evaluate the impact of COVID-19 on Latin American oncology clinical trials. The results are consistent with surveys from other world regions. These findings may endorse improvements in clinical trials' processes and management in the postpandemic period.

PURPOSE: Little is known, or has been published previously, regarding consolidated data on the epidemiology of gynecologic cancers (GC) in Brazil. This article describes the incidence, morbidity, and mortality of women in Brazil affected with GC between the years of 2000 and 2017. METHODS: Incidence, morbidity, and mortality data from patients with a diagnosis of one out of the five most common GC, cervical (CC), uterine (UC), ovarian (OC), vulvar (VvC), and vaginal (VgC), were obtained from three governmental sources of data. RESULTS: From 2000 to 2015 CC, OC, and VgC incidence rates (IRs) decreased, whereas the IRs for UC and VvC remained relatively stable. Data from 382,932 women with GC were analyzed. Most patients presented with locally advanced or advanced disease at diagnosis: 60.1% of patients with CC, 31.2% of patients with UC, 67.2% of patients with OC, 45.2% of patients with VvC, and 67.0% of patients with VgC. Time from diagnosis to first treatment was ≥ 60 days in 58.0% of patients with CC, 58.5% of patients with UC, 27.0% of patients with OC, 55.3% of patients with VvC, and 52.7% of patients with VgC. Regarding mortality rates (MRs), with the exception of CC, UC, and VvC, which showed a slight decrease, MRs remained stable between 2000 and 2017. CONCLUSION: A comparison with international data indicates that Brazilian patients are diagnosed with more advanced disease and face a longer delay between diagnosis and first treatment. Despite advances in screening and treatment, GC mortality has not decreased satisfactorily in this country.
