RESUMEN
BACKGROUND: Peritoneal carcinomatosis (PC) is common in patients with advanced gynecologic and gastrointestinal cancers. Frequently, patients with PC undergo palliative surgery or procedures to manage disease-related complications and side effects. However, there are limited data regarding patients' and family caregivers' decision-making processes about these procedures. Thus, we sought to describe the decision-making experiences of patients with PC who elect to pursue palliative surgical procedures and their family caregivers. METHODS: We conducted a secondary analysis of qualitative data collected during a pilot randomized controlled trial of BOLSTER, a nurse-led telehealth intervention for patients with PC and their caregivers after an acute hospitalization and palliative procedure. Participants in both study arms described their experiences in semi-structured interviews. We re-analyzed coded qualitative data with a focus on understanding decision-making experiences surrounding palliative surgery and procedures using conventional content analysis. RESULTS: Interviews from 32 participants, 23 patients and 9 caregivers, were analyzed. Participants reported their decision-making was complicated by illness uncertainty and a desire for clear, effective communication with surgical and medical oncology teams. Participants requested more information about the impact of palliative procedures on their daily life. Several also noted that, without improved understanding, a misalignment between patient and family caregiver goals and palliative procedures may inadvertently increase suffering. CONCLUSION: Discussions related to patients' goals and preferences can improve the quality of treatment decision-making in patients with PC and their caregivers. Future research should test interventions to improve advanced cancer patients' illness understanding and decision-making surrounding palliative surgery and procedures.
RESUMEN
OBJECTIVE: Patients with advanced gynecologic (GYN) and gastrointestinal (GI) cancers frequently develop peritoneal carcinomatosis (PC), which limits prognosis and diminishes health-related quality of life (HRQoL). Palliative procedures may improve PC symptoms, yet patients and caregivers report feeling unprepared to manage ostomies, catheters, and other complex needs. Our objectives were to (1) assess the feasibility of an efficacy trial of a nurse-led telehealth intervention (BOLSTER) for patients with PC and their caregivers; and (2) assess BOLSTER's acceptability, potential to improve patients' HRQoL and self-efficacy, and potential impact on advance care planning (ACP). METHODS: Pilot feasibility RCT. Recently hospitalized adults with advanced GYN and GI cancers, PC, and a new complex care need and their caregivers were randomized 1:1 to BOLSTER or enhanced discharge planning (EDP). We defined feasibility as a ≥ 50% approach-to-consent ratio and acceptability as ≥70% satisfaction with BOLSTER. We assessed patients' HRQoL and self-efficacy at baseline and six weeks, then compared the proportion experiencing meaningful improvements by arm. ACP documentation was identified using natural language processing. RESULTS: We consented 77% of approached patients. In the BOLSTER arm, 91.0% of patients and 100.0% of caregivers were satisfied. Compared to EDP, more patients receiving BOLSTER experienced improvements in HRQoL (68.4% vs. 40.0%) and self-efficacy for managing symptoms (78.9% vs. 35.0%) and treatment (52.9% vs. 42.9%). The BOLSTER arm had more ACP documentation. CONCLUSIONS: BOLSTER is a feasible and acceptable intervention with the potential to improve patients' HRQoL and promote ACP. An efficacy trial comparing BOLSTER to usual care is underway. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03367247; PI: Wright.
RESUMEN
PURPOSE: To assess efficacy and toxicity of cisplatin (C) and gemcitabine (G) with intensity-modulated radiation therapy (IMRT) in patients with locally advanced vulvar cancer not amenable to surgery. METHODS: Patients enrolled in a single-arm phase II study. Pretreatment inguinal-femoral nodal assessment was performed. Sixty-four Gy IMRT was prescribed to the vulva, with 50-64 Gy delivered to the groins/low pelvis. Radiation therapy (RT) plans were quality-reviewed pretreatment. C 40 mg/m2 and G 50 mg/m2 were administered once per week throughout IMRT. Complete pathologic response (CPR) was the primary end point. Progression-free survival (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method, and adverse events were assessed with Common Terminology Criteria for Adverse Events v 4.0. RESULTS: Fifty-seven patients enrolled, of which 52 were evaluable. The median age was 58 years (range, 25-58), and 94% were White. Forty (77%) had stage II or III disease, and all had squamous histology. A median of six chemotherapy cycles (range, 1-8) were received. Eighty-five percent of RT plans were quality-reviewed with 100% compliance to protocol. Seven patients came off trial because of toxicity or patient withdrawal. Of 52 patients available for pathologic assessment, 38 (73% [90% CI, 61 to 83]) achieved CPR. No pelvic exenterations were performed. With a median follow-up of 51 months, the 12-month PFS was 74% (90% CI, 62.2 to 82.7) and the 24-month OS was 70% (90% CI, 57 to 79). The most common grade 3 or 4 adverse events were hematologic toxicity and radiation dermatitis. There was one grade 5 event unlikely related to treatment. CONCLUSION: Weekly C and G concurrent with IMRT sufficiently improved CPR in women with locally advanced vulvar squamous cell carcinoma not amenable to surgical resection.

OBJECTIVE: To assess the potential relationship of clinical status upon admission and distance traveled from geographical health district in women with gestational trophoblastic disease (GTD). METHODS: This is a cross-sectional study including women with GTD from the 17 health districts from the São Paulo state (I-XVII), Brazil, referred to the Botucatu Trophoblastic Disease Center (specialized center, district VI), between 1990 and 2018. At admission, hydatidiform mole was assessed according to the risk score system of Berkowitz et al. Gestational trophoblastic neoplasia was evaluated using the International Federation of Gynecology and Obstetrics / World Health Organization (FIGO/WHO) staging/risk score. Data on demographics, clinical status and distance traveled were collected. Multiple regression analyses were performed. RESULTS: This study included 366 women (335 hydatidiform mole, 31 gestational trophoblastic neoplasia). The clinical status at admission and distance traveled significantly differed between the specialized center district and other districts. Patients referred from health districts IX (ß = 2.38 [0.87-3.88], p = 0.002) and XVI (ß = 0.78 [0.02-1.55], p = 0.045) had higher hydatidiform mole scores than those from the specialized center district. Gestational trophoblastic neoplasia patients from district XVI showed a 3.32 increase in FIGO risk scores compared with those from the specialized center area (ß = 3.32, 95% CI = 0.78-5.87, p = 0.010). Distance traveled by patients from districts IX (200km) and XVI (203.5km) was significantly longer than that traveled by patients from the specialized center district (76km). CONCLUSION: Patients from health districts outside the specialized center area had higher risk scores for both hydatidiform mole and gestational trophoblastic neoplasia at admission. Long distances (>80 km) seemed to adversely influence gestational trophoblastic disease clinical status at admission, indicating barriers to accessing specialized centers.
OBJETIVO: Avaliar a possível relação entre estado clínico na apresentação e distância percorrida a partir do distrito de saúde em mulheres com doença trofoblástica gestacional. MéTODOS: Estudo transversal incluindo mulheres com doença trofoblástica gestacional dos 17 distritos de saúde do estado de São Paulo (IXVII), Brasil, encaminhadas ao Centro de Doenças Trofoblásticas de Botucatu (distrito VI), entre 1990 e 2018. Na admissão, avaliaram-se mola hidatiforme pelo sistema de pontuação de risco de Berkowitz et al. e neoplasia trofoblástica gestacional pelo escore de risco/estadiamento Federação Internacional de Ginecologia e Obstetrícia / Organização Mundial da Saúde (FIGO/OMS). Coletaram-se dados demográficos, clínicos e distância percorrida e análises de regressão múltipla foram realizadas. RESULTADOS: Este estudo incluiu 366 mulheres (335 mola hidatiforme, 31 neoplasia trofoblástica gestacional). O estado clínico na apresentação e distância percorrida diferiram significativamente entre o centro especializado e demais distritos. Nas pacientes encaminhadas pelos distritos IX (ß = 2,38 [0,873,88], p = 0,002) e XVI (ß = 0,78 [0,021,55], p = 0,045), os escores de mola hidatiforme foram maiores que no centro especializado. As pacientes com neoplasia trofoblástica gestacional do distrito XVI apresentaram escores FIGO 3,32 vezes maior que no centro especializado (ß = 3,32, 95% CI = 0,785,87, p = 0,010). A distância percorrida pelas pacientes dos distritos IX (200km) e XVI (203,5km) foi significativamente maior do que a percorrida pelas pacientes do centro especializado (76km). CONCLUSãO: Pacientes de distritos de saúde fora da cobertura do centro especializado apresentaram escores de risco mais alto para mola hidatiforme e para neoplasia trofoblástica gestacional na admissão. Longas distâncias (>80 km) pareceram influenciar negativamente o estado clínico da doença trofoblástica gestacional na apresentação, indicando barreiras no acesso a centros especializados.

OBJECTIVE: To evaluate the efficacy of immunotherapy for GTN treatment after methotrexate-resistance or in cases of multiresistant disease, through a systematic review, as well as to present the first 4 Brazilian cases of immunotherapy for GTN treatment. METHODS: Three independent researchers searched five electronic databases (EMBASE, LILACS, Medline, CENTRAL and Web of Science), for relevant articles up to February/2023 (PROSPERO CRD42023401453). The quality assessment was performed using the Newcastle Ottawa scale for case series and case reports. The primary outcome of this study was the occurrence of complete remission. The presentation of the case reports was approved by the Institutional Review Board. RESULTS: Of the 4 cases presented, the first was a low-risk GTN with methotrexate resistance unsuccessfully treated with avelumab, which achieved remission with sequential multiagent chemotherapy. The remaining 3 cases were high-risk multiagent-resistant GTN that were successfully treated with pembrolizumab, among which there were two subsequent gestations, one of them with normal pregnancy and healthy conceptus. Regarding the systematic review, 12 studies were included, only one of them on avelumab, showing a 46.7% complete remission rate. The remaining 11 studies were on pembrolizumab, showing an 86.7% complete remission rate, regardless of tumor histology. Both immunotherapies showed good tolerability, with two healthy pregnancies being recorded: one after avelumb and another after pembrolizumab. CONCLUSION: Immunotherapy showed effectiveness for GTN treatment and may be especially useful in cases of high-risk disease, where pembrolizumab achieves a high therapeutic response, regardless of the histological type, and despite prior chemoresistance to multiple lines of treatment.

OBJECTIVE: To relate the distance traveled from the patient's residence to the gestational trophoblastic neoplasia (GTN) reference center (RC) and the occurrence of unfavorable clinical outcomes, as well as to estimate the possible association between this distance and the risk of metastatic disease at presentation, the need for multiagent chemotherapy to achieve remission and loss to follow-up before remission. STUDY DESIGN: Retrospective historical cohort study of patients with GTN followed at 8 Brazilian GTN-RC, from January 1st, 2000 - December 31st, 2017. RESULTS: Evaluating 1055 cases of GTN, and using a receiver operating characteristic curve, we found a distance of 56 km (km) from the residence to the GTN-RC (sensitivity = 0.57, specificity = 0.61) best predicted the occurrence of at least one of the following outcomes: occurrence of metastatic disease, need for multiagent chemotherapy to achieve remission, or loss to follow-up during chemotherapy. Multivariate logistic regression adjusted by age, ethnicity, marital status and the reference center location showed that when the distance between residence and GTN-RC was ≥56 km, there was an increase in the occurrence of metastatic disease (relative risk - RR:3.27; 95%CI:2.20-4.85), need for multiagent chemotherapy (RR:1.36; 95%CI:1.05-1.76), loss to follow-up during chemotherapy (RR:4.52; 95CI:1.93-10.63), occurrence of chemoresistance (RR:4.61; 95%CI:3.07-6.93), relapse (RR:10.27; 95%CI:3.08-34.28) and death due to GTN (RR:3.62; 95%CI:1.51-8.67). CONCLUSIONS: The distance between the patient's residence and the GTN-RC is a risk factor for unfavorable outcomes, including death from this disease. It is crucial to guarantee these patients get prompt access to the GTN-RC and receive follow-up support.

OBJECTIVE: To investigate the efficacy and toxicity of etoposide, methotrexate, actinomycin D alternating with cyclophosphamide, and vincristine (EMACO) for treatment of gestational trophoblastic neoplasia, and for factors independently associated with EMACO resistance and disease-specific death in an international cohort. METHODS: Medical records of GTN patients who received EMACO during 1986-2019 from gestational trophoblastic disease centers from four countries including the USA, Thailand, Hungary, and Brazil, were retrospectively reviewed. Among 335 GTN patients, 266 patients who received EMACO as primary chemotherapy were included in the primary treatment group, and 69 patients who received EMACO after relapse/resistance to single-agent chemotherapy were included in the prior treatment group. RESULTS: Three-quarters (76.1%) of all patients achieved remission, and the survival rate was 89%. The prior treatment group had better outcomes than the primary treatment group relative to remission rate (87.0% vs. 73.3%, p = 0.014) and number of EMACO cycles to achieve remission (3 vs. 6 cycles, p < 0.001). Sustained remission increased to 87.2% in EMACO-resistant patients treated with later-line chemotherapy. Number of metastatic organs ≥2 (adjusted odds ratio [aOR]: 2.33, p = 0.049) was the only independent predictor of EMACO resistance among overall patients. Interval from index pregnancy ≥7 months (aOR: 4.34, p = 0.001), and pretreatment hCG >100,000 IU/L (aOR: 2.85, p = 0.028) were independent predictors of EMACO resistance in the high-risk subgroup. The only factor independently associated with disease-specific death was EMACO resistance (aOR: 176.04, p < 0.001). CONCLUSIONS: EMACO is an effective treatment for GTN. Number of metastatic organs and EMACO resistance were the independent predictors of EMACO resistance and disease-specific death, respectively.

OBJECTIVE: To describe the natural history of hydatidiform mole (HM) after intracytoplasmic sperm injection (ICSI), emphasizing the clinical and oncological outcomes, as compared to patients who had HM after spontaneous conception (SC). STUDY DESIGN: Retrospective historical cohort study of patients with HM followed at the Rio de Janeiro Federal University, from January 1st 2000-December 31st 2020. RESULTS: Comparing singleton HM after SC to those following ICSI there were differences in terms of maternal age (24 vs 34 years, p < 0.01), gestational age at diagnosis (10 vs 7 weeks, p < 0.01), preevacuation human chorionic gonadotropin levels (200,000 vs 99,000 IU/L, p < 0.01), occurrence of genital bleeding (60.5 vs 26.9%, p < 0.01) and hyperemesis (23 vs 3.9%, p = 0.02) at presentation, and time to remission (12 vs 5 weeks, p < 0.01), respectively. There were no differences observed in the cases of twin mole, regardless of the form of fertilization that gave rise to HM, except molar histology with greater occurrence of partial hydatidiform mole (10.7 vs 40.0%, p = 0.01) following ICSI. Univariate logistic regression for occurrence of postmolar GTN after ICSI identified no predictor variable for this outcome. However, after adjusting for maternal age and complete hydatidiform mole histology, multivariable logistic regression showed the risk of GTN with HM after ICSI had an adjusted odds ratio of 0.22 (95%CI:0.05-0.93, p = 0.04), suggesting a possible protective effect when compared to HM after SC. CONCLUSIONS: Singleton HM after ICSI are diagnosed earlier in gestation, present with fewer medical complications, and may be less likely to develop GTN when compared with HM after SC.

INTRODUCTION: Gestational trophoblastic neoplasia (GTN) is a rare tumor that arises from trophoblastic tissues with high remission rates after chemotherapy treatment. GTN can develop from any gestational events, such as miscarriage, ectopic pregnancy, and preterm/term pregnancy, but is more frequent after hydatidiform mole. The sensitivity of this tumor to chemotherapy and the presence of an exceptional tumor marker allow high remission rates, especially when patients are treated in referral centers. AREAS COVERED: Observational, retrospective, prospective, systematic reviews, and meta-analysis studies focusing on GTN treatment. We searched PubMed, Medline, and the Library of Congress from January 1965 to May 2022. EXPERT OPINION: Early GTN diagnosis allows low-toxic and highly effective treatment. Even multimetastatic disease has high rates of remission with multiagent regimen chemotherapy. Surgery is reserved for uterine disease in patients who have completed childbearing, in cases of chemoresistance to multiagent regimens or in the rare cases of placental site trophoblastic tumor or epithelioid trophoblastic tumor. While resistance is managed by salvage chemotherapy, cases with limited clinical response to sequential regimens have been successfully treated with immunotherapy.

OBJECTIVE: To assess whether the incidence and aggressiveness of molar pregnancy (MP) and postmolar gestational trophoblastic neoplasia (GTN) changed during the COVID-19 pandemic. DESIGN: Observational study with two separate designs: retrospective multicentre cohort of patients with MP/postmolar GTN and a cross-sectional analysis, with application of a questionnaire. SETTING: Six Brazilian Reference Centres on gestational trophoblastic disease. POPULATION: 2662 patients with MP/postmolar GTN treated from March-December/2015-2020 were retrospectively evaluated and 528 of these patients answered a questionnaire. METHODS: Longitudinal retrospective multicentre study of patients diagnosed with MP/ postmolar GTN at presentation and a cross-sectional analysis, with application of a questionnaire, exclusive to patients treated during the period of study, to assess living and health conditions during the COVID-19 pandemic compared with previous years. MAIN OUTCOME MEASURES: The incidence of MP/postmolar GTN. RESULTS: Compared with the last 5 pre-pandemic years, MP/postmolar GTN incidence remained stable during 2020 (COVID-19 pandemic). Multivariable logistic regression, adjusted for the patient age, showed that during 2020, presentation with MP was more likely to be >10 weeks of gestation (adjusted odds ratio [aOR] 2.50, 95% confidence interval [CI] 1.90-3.29, P < 0.001), have a pre-evacuation hCG level ≥100 000 iu/l (aOR 1.77, 95% CI 1.38-2.28, P < 0.001) and time to the initiation of chemotherapy ≥7 months (aOR 1.86, 95% CI 1.01-3.43, P = 0.047) when compared with 2015-2019. CONCLUSIONS: Although the incidence of MP/postmolar GTN remained stable during the COVID-19 pandemic in Brazil, the pandemic was associated with greater gestational age at MP diagnosis and more protracted delays in initiation of chemotherapy for postmolar GTN.

PURPOSE: Estrogen receptor (ER)-positive endometrial cancers (ECs) are characterized by phosphatidylinositol 3-kinase (PI3K) and receptor tyrosine kinase (RTK)/RAS/ß-catenin (CTNNB1) pathway alterations in approximately 90% and 80% of cases, respectively. Extensive cross-talk between ER, PI3K, and RTK/RAS/CTNNB1 pathways leads to both ligand-dependent and ligand-independent ER transcriptional activity as well as upregulation of cyclin D1 which, in complex with cyclin-dependent kinases 4 and 6 (CDK4 and CDK6), is a critical regulator of cell cycle progression and a key mediator of resistance to hormonal therapy. We hypothesized that the combination of the aromatase inhibitor letrozole and CDK4/6 inhibitor abemaciclib would demonstrate promising activity in this setting. METHODS: We conducted a phase II, two-stage study of letrozole/abemaciclib in recurrent ER-positive EC. Eligibility criteria included measurable disease, no limit on prior therapies, and all EC histologies; prior hormonal therapy was allowed. Primary end points were objective response rate by RECIST 1.1 and progression-free survival (PFS) rate at 6 months. RESULTS: At the data cutoff date (December 03, 2021), 30 patients (28 with endometrioid EC) initiated protocol therapy; 15 (50%) patients had prior hormonal therapy. There were nine total responses (eight confirmed), for an objective response rate of 30% (95% CI, 14.7 to 49.4), all in endometrioid adenocarcinomas. Median PFS was 9.1 months, PFS at 6 months was 55.6% (95% CI, 35.1 to 72), and median duration of response was 7.4 months. Most common ≥ grade 3 treatment-related adverse events were neutropenia (20%) and anemia (17%). Responses were observed regardless of grade, prior hormonal therapy, mismatch repair, and progesterone receptor status. Exploratory tumor profiling revealed several mechanistically relevant candidate predictors of response (CTNNB1, KRAS, and CDKN2A mutations) or absence of response (TP53 mutations), which require independent validation. CONCLUSION: Letrozole/abemaciclib demonstrated encouraging and durable evidence of activity in recurrent ER positive endometrioid EC.

Abstract Objective To evaluate the efficacy of immunotherapy for GTN treatment after methotrexate-resistance or in cases of multiresistant disease, through a systematic review, as well as to present the first 4 Brazilian cases of immunotherapy for GTN treatment. Methods Three independent researchers searched five electronic databases (EMBASE, LILACS, Medline, CENTRAL and Web of Science), for relevant articles up to February/2023 (PROSPERO CRD42023401453). The quality assessment was performed using the Newcastle Ottawa scale for case series and case reports. The primary outcome of this study was the occurrence of complete remission. The presentation of the case reports was approved by the Institutional Review Board. Results Of the 4 cases presented, the first was a low-risk GTN with methotrexate resistance unsuccessfully treated with avelumab, which achieved remission with sequential multiagent chemotherapy. The remaining 3 cases were high-risk multiagent-resistant GTN that were successfully treated with pembrolizumab, among which there were two subsequent gestations, one of them with normal pregnancy and healthy conceptus. Regarding the systematic review, 12 studies were included, only one of them on avelumab, showing a 46.7% complete remission rate. The remaining 11 studies were on pembrolizumab, showing an 86.7% complete remission rate, regardless of tumor histology. Both immunotherapies showed good tolerability, with two healthy pregnancies being recorded: one after avelumb and another after pembrolizumab. Conclusion Immunotherapy showed effectiveness for GTN treatment and may be especially useful in cases of high-risk disease, where pembrolizumab achieves a high therapeutic response, regardless of the histological type, and despite prior chemoresistance to multiple lines of treatment.
RESUMEN
OBJECTIVE: To relate preevacuation platelet count and leukogram findings, especially neutrophil/lymphocyte ratios (NLR) and platelet/lymphocyte ratios with the occurrence of gestational trophoblastic neoplasia (GTN) after complete hydatidiform mole (CHM) among Brazilian women. METHODS: Retrospective cohort study of patients with CHM followed at Rio de Janeiro Federal University, from January/2015-December/2020. Before molar evacuation, all patients underwent a medical evaluation, complete blood count and hCG measurement, in addition to other routine preoperative tests. The primary outcome was the occurrence of postmolar GTN. RESULTS: From 827 cases of CHM treated initially at the Reference Center, 696 (84.15%) had spontaneous remission and 131 (15.85%) developed postmolar GTN. Using optimal cut-offs from receiver operating characteristic curves and multivariable logistic regression adjusted for the possible confounding variables of age and preevacuation hCG level (already known to be associated with the development of GTN) we found that ≥2 medical complications at presentation (aOR: 1.96, CI 95%: 1.29-2.98, p<0.001) and preevacuation hCG ≥100,000 IU/L (aOR: 2.16, CI 95%: 1.32-3.52, p<0.001) were significantly associated with postmolar GTN after CHM. However, no blood count profile findings were able to predict progression from CHM to GTN. CONCLUSION: Although blood count is a widely available test, being a low-cost test and mandatory before molar evacuation, and prognostic for outcome in other neoplasms, its findings were not able to predict the occurrence of GTN after CHM. In contrast, the occurrence of medical complications at presentation and higher preevacuation hCG levels were significantly associated with postmolar GTN and may be useful to guide individualized clinical decisions in post-molar follow-up and treatment of these patients.

BACKGROUND: The combination of paclitaxel to platinum remains the backbone of therapy in patients with advanced Mullerian tumors. In patients with newly diagnosed Mullerian tumors, we investigated the progression-free survival benefit of bevacizumab and bevacizumab and erlotinib as consolidation therapy post-induction therapy. METHODS: Sixty patients were enrolled in a phase II trial of carboplatin, paclitaxel, and bevacizumab (induction therapy). After the completion induction therapy, patients were stratified by response (≥ SD) and then randomized (1:1) to either bevacizumab (A) or bevacizumab and erlotinib (AE.) The primary endpoint was PFS. Secondary endpoints included the response rate of induction and consolidation therapy and toxicity profile of each consolidative arm. Each consolidative arm was compared to the historical control GOG 111. RESULTS: Forty-eight patients advanced to the consolidative phase of the trial. Twelve patients were removed in the induction phase, the majority for toxicity. The most common toxicity (grade ≥ 3) was diarrhea (20%: arm AE; 0%: arm A). One patient in the AE arm had a fatal cardiac arrest deemed unrelated to the study treatment. No gastrointestinal perforations were reported. The median PFS in the AE and A arm was 18.9 months (p < 0.0001) and 13.3 months (p: ns), respectively. The overall rate of grade 3/4 toxicities in the AE arm was 72% and in the A arm 30%. Six patients remain free of disease 10 years after enrollment. CONCLUSION: Combinatorial consolidation therapy with AE was associated with an improved progression-free survival in patients with Mullerian tumors.

Female carriers of pathogenic/likely pathogenic (P/LP) BRCA1/2 variants are at increased risk of developing breast and ovarian cancer. Currently, the only effective strategy for ovarian cancer risk reduction is risk-reducing bilateral salpingo-oophorectomy (RR-BSO), which carries adverse effects related to early menopause. There is ongoing investigation of inhibition of the RANK ligand (RANKL) with denosumab as a means of chemoprevention for breast cancer in carriers of BRCA1 P/LP variants. Through the NCI Division of Cancer Prevention (DCP) Early Phase Clinical Trials Prevention Consortia, a presurgical pilot study of denosumab was developed in premenopausal carriers of P/LP BRCA1/2 variants scheduled for RR-BSO with the goal of collecting valuable data on the biologic effects of denosumab on gynecologic tissue. The study was terminated early due to the inability to accrue participants. Challenges which impacted the conduct of this study included a study design with highly selective eligibility criteria and requirements and the COVID-19 pandemic. It is critical to reflect on these issues to enhance the successful completion of future prevention studies in individuals with hereditary cancer syndromes.

Abstract Objective There are few multinational studies on gestational trophoblastic neoplasia (GTN) treatment outcomes in South America. The purpose of this study was to assess the clinical presentation, treatment outcomes, and factors associated with chemoresistance in low-risk postmolar GTN treated with first-line single-agent chemotherapy in three South American centers. Methods Multicentric, historical cohort study including women with International Federation of Gynecology and Obstetrics (FIGO)-staged low-risk postmolar GTN attending centers in Argentina, Brazil, and Colombia between 1990 and 2014. Data were obtained on patient characteristics, disease presentation, and treatment response. Logistic regression was used to assess the relationship between clinical factors and resistance to first-line single-agent treatment. A multivariate analysis of the clinical factors significant in univariate analysis was performed. Results A total of 163 women with low-risk GTN were included in the analysis. The overall rate of complete response to first-line chemotherapy was 80% (130/163). The rates of complete response to methotrexate or actinomycin-D as first-line treatment, and actinomycin-D as second-line treatment postmethotrexate failure were 79% (125/157), 83% (⅚), and 70% (23/33), respectively. Switching to second-line treatment due to chemoresistance occurred in 20.2% of cases (33/163). The multivariate analysis demonstrated that patients with a 5 to 6 FIGO risk score were 4.2-fold more likely to develop resistance to first-line single-agent treatment (p= 0.019). Conclusion 1) At presentation, most women showed clinical characteristics favorable to a good outcome, 2) the overall rate of sustained complete remission after first-line single-agent treatment was comparable to that observed in developed countries, 3) a FIGO risk score of 5 or 6 is associated with development of resistance to first-line single-agent chemotherapy.

Importance: Although the activity of pembrolizumab and lenvatinib (the only US Food and Drug Administration-approved immunotherapy for mismatch repair proficient endometrial cancer [MMRP EC]) is compelling, there are no biomarkers of response and most patients do not tolerate, do not respond to, or develop resistance to this regimen, highlighting the need for additional, potentially biomarker-driven therapeutic approaches for patients with recurrent MMRP EC. Objective: To assess the potential positive outcomes and safety of the combination of the polyadenosine diphosphate-ribose polymerase inhibitor talazoparib and the programmed cell death ligand 1 (PD-L1) inhibitor avelumab in recurrent MMRP EC. Design, Settings, and Participants: This investigator-initiated, open-label, single-arm, 2-stage, phase 2 study nonrandomized controlled trial patients at 4 institutions in the US. Key eligibility criteria included measurable disease, unlimited prior therapies, and all endometrial cancer histologies. Interventions: Talazoparib, 1 mg, orally, daily, and avelumab, 10 mg/kg, intravenously, every 2 weeks, were administered until disease progression or unacceptable toxic effects. Main Outcomes and Measures: Statistical considerations were developed for 2 coprimary objectives of objective response rate and rate of progression-free survival at 6 months, with a 2-stage design that allowed for early discontinuation for futility. Prespecified exploratory objectives included the association of immunogenomic features (determined by targeted-panel next-generation sequencing and immunohistochemistry) with activity. Results: Thirty-five female patients (mean [SD] age, 67.9 [8.41] years) received protocol therapy; 9 (25.7%) derived clinical benefit after meeting at least 1 of the 2 coprimary end points. Four patients (11.4%) exhibited confirmed objective response rates (4 partial responses), and 8 (22.9%) survived progression free at 6 months. The most common grade 3 and 4 treatment-related toxic effects were anemia (16 [46%]), thrombocytopenia (10 [29%]), and neutropenia (4 [11%]); no patient discontinued receipt of therapy because of toxic effects. Tumors with homologous recombination repair alterations were associated with clinical benefit from treatment with avelumab and talazoparib. Tumor mutational burden, tumor-infiltrating lymphocytes, and PD-L1 status were not associated with clinical benefit. Conclusions and Relevance: The results of this nonrandomized controlled trial suggest that treatment with avelumab and talazoparib demonstrated a favorable toxic effect profile and met the predetermined criteria to be considered worthy of further evaluation in MMRP EC. Immunogenomic profiling provided insights that may inform ongoing and future studies of polyadenosine diphosphate-ribose polymerase and PD-L1 inhibitor combinations in endometrial cancer. Trial Registration: ClinicalTrials.gov Identifier: NCT02912572.
