Elderly Patients with Metastatic Neuroendocrine Tumors Are Undertreated and Have Shorter Survival: The LyREMeNET Study.

INTRODUCTION: The incidence of neuroendocrine tumors (NETs) is rising, especially in elderly patients. The elderly cancer population presents considerable challenges, yet little is known about the characteristics, treatment patterns, and outcomes of metastatic NET (mNET) patients. METHODS: The Lyon Real-life Evidence in Metastatic NeuroEndocrine Tumors study (LyREMeNET, NCT03863106) included consecutive mNET patients, diagnosed between January 1990 and December 2017. The exclusion criteria were nonmetastatic NET, poorly differentiated neuroendocrine carcinoma, and mixed neuroendocrine-nonneuroendocrine neoplasms. We aimed to compare patients ≥70 years old to patients <70 years old. RESULTS: A total of 866 patients were included, 198 (23%) were ≥70 years old. There was no significant difference in characteristics except that elderly patients had synchronous metastasis more frequently. Elderly patients received significantly fewer treatments (median of 2.0 vs. 3.0 lines, respectively, p < 0.0001), were significantly less frequently treated by chemotherapy (32 vs. 54%), targeted therapy (16 vs. 30%), peptide receptor radionuclide therapy (5 vs. 16%), and they underwent significantly less frequently locoregional intervention. Median overall survival was significantly shorter in elderly patients (5.2 vs. 9.6 years). The most frequent cause of death was related to disease progression (71%). Multivariate analysis found that, after adjustment for tumor location, tumor grade, and number of metastatic sites, age remained significantly associated with overall survival (HR 1.66, 95% CI 1.26-2.18), indicating a poorer survival in patients ≥70 years old in comparison with younger patients (p = 0.0003). CONCLUSION: Patients ≥70 years old have a worse survival, die frequently from their disease, and are undertreated compared to younger patients.

Neuroendocrine Carcinoma of the Urinary Bladder: A Large, Retrospective Study From the French Genito-Urinary Tumor Group.

BACKGROUND: Neuroendocrine carcinoma of the urinary bladder (NCUB) is rare, accounting for < 1% of bladder cancer cases, with scarce reported data available. MATERIALS AND METHODS: We retrospectively reviewed the data from patients with NCUB treated at French institutions. The objectives were to describe the patient characteristics, treatments received, and outcomes (ie, disease-free survival [DFS], progression-free survival, overall survival [OS]) and investigate the prognostic factors. RESULTS: From 1997 to 2017, we included 236 patients, 173 with early-stage NCUB and 63 with advanced-stage NCUB. For those with early-stage disease, the median DFS was better for the patients who had received cisplatin-based chemotherapy compared with carboplatin (hazard ratio [HR], 1.95; 95% confidence interval [CI], 1.1-3.46), with no difference found between the neoadjuvant and adjuvant settings (HR, 1.1; 95% CI, 0.61-1.97). The median OS was 36 months (95% CI, 29-43 months) for stage I and II, 26 months (95% CI, 18 months to not reached) for stage IIIA, 16 months (95% CI, 12-21 months) for stage IIIB. The HR for stage IIIB compared with stage I/II was 2.6 (95% CI, 1.5-4.4). The DFS at 6 months was associated with OS (HR, 7.8; 95% CI, 4.1-15.0). For patients with metastases at diagnosis who had received chemotherapy, the median progression-free survival was 9 months (95% CI, 8-11) for first-line cisplatin and 6 months (95% CI, 4-13 months) for carboplatin; the median OS was 13 months (95% CI, 9-15 months). A high-risk Bajorin score (HR, 11.5; 95% CI, 1.2-112.6) and the use of carboplatin (HR, 2.26; 95% CI, 1.03-4.96) were associated with worse outcomes. CONCLUSIONS: In early-stage disease, a shorter DFS was associated with worse OS, and the use of cisplatin was associated with better OS. For the patients with metastases at diagnosis, a high-risk Bajorin score and the use of carboplatin were associated with worse outcomes.

[Expectation about maintenance therapy among the GINECO French ovarian cancer cohort from the European NOGGO/ENGOT-ov22 Expression IV survey]. / Attentes des patientes suivies pour un cancer de l'ovaire concernant les traitements d'entretien : résultats de la cohorte française GINECO de l'enquête européenne NOGGO/ENGOT-ov22 (Expression IV).

BACKGROUND: Expression IV survey evaluated the patients' expectations to a maintenance therapy. METHODS: From January 2015 to March 2016, 401 French patients, in first line or recurrent disease, answered a 24-items anonymous questionnaire. The results were specifically analyzed according to the demographic characteristics and treatment lines. RESULTS: Among the patients, 62% had already been informed about maintenance therapy. Thirty-seven percent of patients received a maintenance treatment: 111 patients during first line and 39 patients in relapse. Expectations of patients were: 1) the chance of cure (73%), 2) the tumor shrinkage (36%), 3) quality of life improvement (35%) and 4) tumor growth reduction (27%). Among the responders, 42% were willing to take the treatment for 6-24 months, 20% for 24-60 months and 38% until tumor progression. 64% of patients expected more than a 6 months progression-free survival. Patients older than 70 years were less informed than their younger counterparts (48% vs 66%) and had lesser hope for cure with maintenance treatment (60% vs 77%). Patients in relapse had more expectation than patients in remission (tumor shrinkage: 47% vs 22%, slowing of tumor growth: 37% vs 15%, improving the progression-free survival of more than 6 months: 71% vs 53%, respectively). Among patients, 48% in relapse consented to take a treatment until progression vs 24% of patients in remission. CONCLUSION: This sub-analysis in French patients demonstrate a gap between the efficacy of maintenance therapy and the patients' expectations in ovarian cancer, particularly in relapsing disease justifying better information and explanations.
