Clinical outcome of advanced or recurrent endometrial carcinoma treated with chemotherapy: a French observational retrospective cohort: the ENDOVIE study

Objective Advanced or recurrent endometrial carcinoma (EC) represents a significant clinical challenge. This study aimed to evaluate patient (age and comorbidities) and disease (histological subtypes and stages) characteristics, treatment patterns and survival outcomes in a real-world French healthcare setting. Methods and analysis In this national, multi-centre, retrospective observational cohort study, 200 patients with advanced or recurrent EC receiving first- or second-line chemotherapy during the year 2019 were analysed. Data collected included baseline characteristics, treatment regimens, real-world progression-free survival (rwPFS) and overall survival (OS). Results 127 and 73 were included in the first and second lines, respectively. Endometrioid carcinoma was the most represented histological subtype (62.0%). Patients in the first line, of whom 31.5% had FIGO (Fédération Internationale de Gynécologie Obstétrique) IVB disease, mainly received a combination of carboplatin and paclitaxel (78.0%), while 131 patients receiving second-line therapy were mainly administered anthracycline (54.2%). Median rwPFS and OS were, respectively, 8.5 and 13.2 months for patients receiving first-line therapy and 4.0 and 9.4 months for patients receiving second-line therapy. In Cox analyses, a diagnosis of carcinosarcoma, the presence of liver metastases and stage IVB disease were associated with worse survival outcomes for patients recieving first-line chemotherapy. Non-platinum chemotherapy and liver metastases were associated with poorer survival in patients receiving second-line chemotherapy. Conclusions This study highlights the landscape of metastatic EC treatment in a real-world French setting before the availability of PD1 inhibitors, emphasising the discrepancy between clinical trial data and real-world outcomes. It underscores the necessity for further real-world studies to complement clinical trials for a comprehensive understanding of metastatic EC management.

Endocrine therapy in advanced high-grade ovarian cancer: real-life data from a multicenter study and a review of the literature

Abstract Background In women, ovarian cancer is the eighth most frequent cancer in incidence and mortality. It is often diagnosed at advanced stages; relapses are frequent, with a poor prognosis. When platinum resistant, subsequent lines of chemotherapy are of limited effect and often poorly tolerated, leading to quality of life deterioration. Various studies suggest a hormonal role in ovarian carcinogenesis, with a rationale for endocrine therapy in these cancers. Patients and Methods This multicenter, retrospective study assessed the use of endocrine treatment for high-grade ovarian epithelial carcinomas treated between 2010 and 2020. Results Eighty-one patients with ovarian cancers were included. The median duration of platinum sensitivity was 29 months. We observed a 35% disease control rate with endocrine therapy, and 10% reported symptom improvement. For 19 patients (23.5%), the disease was stabilized for more than 6 months. Median overall survival from diagnosis was 62.6 months. Regarding endocrine therapy predictive factors of response, in a multivariate analysis, 3 factors were statistically significant in favoring progression-free survival: platinum sensitivity (P = .021), an R0 surgical resection (P = .020), and the indication for hormone therapy being maintenance therapy (P = .002) Conclusion This study shows real-life data on endocrine therapy in ovarian cancer. As it is a low-cost treatment with many advantages such as its oral administration and its safety, it may be an option to consider. A perspective lies in the search for cofactors to aim as future therapeutic targets to improve the effectiveness of hormone treatment by means of combination therapy.
