Endometrial cancer (EC) is the second most common gynecological malignancy worldwide, the first in developed countries [Sung et al. in CA Cancer J Clin 71:209-249, 2021]. Although a majority is diagnosed at an early stage with a low risk of relapse, an important proportion of patients will relapse. Better knowledge of molecular abnormalities is crucial to identify high-risk groups in early stages as well as for recurrent or metastatic disease for whom adjuvant treatment must be personalized. The objective of this guide is to summarize the current evidence for the diagnosis, treatment, and follow-up of EC, and to provide evidence-based recommendations for clinical practice. © 2022.

Neuroendocrine neoplasm occurs predominantly in the lungs, but can be occasionally found in the gastrointestinal and genitourinary tracts [1]. When this neoplasia affects the genital tract, usually involve the uterine cervix and the ovary [2]. Neuroendocrine tumors are classified as poorly-differentiated and well differentiated, and further categorized into small and large cell neuroendocrine carcinomas. Approximately only 90 cases of small cell neuroendocrine carcinoma of the endometrium have been reported [3,4]. Studies of large cell endometrial neuroendocrine carcinoma (LCNEC) are even less common, with only 16 cases documented [1,5,6]. Our case concerns a 58-year-old woman with a metastatic LCNEC arising from the endometrium. We, correspondingly, also reviewed the literature and emphasize the most important diagnostic and therapeutic aspects of this rare clinical entity.

Simple Summary Since the irruption of PARPi in the therapeutic armamentarium for ovarian cancer, concerns regarding post-progression treatment outcomes have emerged, owing to known crossed-resistance mechanisms between PARPi and platinum. In this multicentric retrospective series of ovarian cancer patients, we evaluated chemotherapy results upon progression to maintenance with PARPi in the relapsed setting. We further selected the population of platinum-sensitive patients (according to the classical definition) retreated with platinum (n = 74). In this platinum-sensitive population, overall response rate and survival outcomes of platinum rechallenge after PARPi were similar to historical series of the prePARPi era. However, within this group, analysis according to BRCA status showed that BRCA mutant patients (n = 35) presented higher rates of progression and worse survival outcomes under subsequent platinum than BRCA wild type patients (n = 39), with statistically significant differences. This is the largest real-world data series of ovarian cancer patients treated with platinum rechallenge in the post-PARPi scenario. Background: Despite impressive progression-free survival (PFS) results from PARP inhibitors (PARPi) in ovarian cancer, concerns about their effect on post-progression treatment outcomes have recently arisen, particularly when administered in the relapsed setting. Overlapping mechanisms of resistance between PARPi and platinum have been described, and optimal therapies upon progression to PARPi are unknown. We communicate real-world data (RWD) on outcomes of subsequent chemotherapy upon progression to PARPi used as maintenance in ovarian cancer relapses, particularly focusing on platinum rechallenge, according to BRCA status. Methods: Data from high-grade serous or endometrioid ovarian cancer patients who received subsequent chemotherapy after progression to maintenance PARPi in the relapsed setting, in 16 Catalan hospitals between August 2016 and April 2021, and who were followed-up until July 2021, were included. Endpoints were overall response rate (ORR), and PFS and overall survival (OS) measured from the subsequent chemotherapy starting date. Results: 111 patients were included [46 (41.4%) presented pathological BRCA1/2 mutations, 8 (7.5%) in other homologous recombination-related genes]. Sixty-four patients (57.7%) had received two prior chemotherapy lines, including the one immediately prior to PARPi. PARPi were niraparib (n = 60, 54.1%), olaparib (n = 49, 44.1%), and rucaparib (n = 2, 1.8%). A total of 81 patients remained platinum-sensitive (PS population) after progression to PARPi (when progression-free interval [PFI] was >6 months after the last cycle of prior platinum) [median PFI 12.0 months (interquartile range, IQR, 8.8-17.1)]. Of those, 74 were treated with subsequent platinum regimens, with the following results: ORR of 41.9%, median PFS (mPFS) of 6.6 months (95% CI 6-9.2), and median OS (mOS) of 20.6 months (95% CI 13.6-28.9). Analysis of these 74 patients according to BRCA status showed that PFIs for BRCA mutant and non BRCA-mutant patients were 13.6 [IQR11.2-22.2] and 10.3 [IQR 7.4-14.9] months, respectively (p = 0.010); ORR were 40.0% versus 43.6%, respectively; Rates of progression (as best response) to subsequent platinum were 45.7% versus 17.9%, respectively (p = 0.004); mPFS and mOS were 3.5 (95% CI 2.5-8.6) versus 7.5 months (95% CI 6.5-10.1, p = 0.03), and 16.4 (95% CI 9.3-27.5) versus 24.2 months (95% CI 17.2-NR, p = 0.036), respectively. Conclusion: This is the largest series of real-world data on ovarian cancer patients retreated with platinum in the post-PARPi scenario, separately analyzing BRCA mutant and non-mutant patients, to our knowledge. In our platinum-sensitive population, rechallenge with platinum after progression upon PARPi in the 3rd or later lines for ovarian cancer relapses shows relevant ORR and similar PFS outcomes to historical series of the prePARPi era. However, BRCA mutant patients presented significantly higher rates of progression under subsequent platinum and worse survival outcomes associated with subsequent platinum than non-BRCA-mutant patients.

Cervical cancer; Staging; Treatment Cáncer de cuello uterino; Puesta en escena; Tratamiento Càncer de coll uterí; Posada en escena; Tractament Cervical cancer (CC) is the fourth most common cancer in women worldwide, strongly linked to high-risk human papilloma virus infection. In high-income countries, the screening programs have dramatically decreased the incidence of CC; however, the lack of accessibility to them in developing countries makes CC an important cause of mortality. Clinical stage is the most relevant prognostic factor in CC. The new FIGO staging system published in 2018 is more accurate than the previous one since it takes into account the lymph node status. In early stages, the primary treatment is surgery—with some concerns recently raised regarding minimally invasive surgery because it might decrease survival—or radiotherapy, whereas concomitant chemo-radiotherapy is the conventional approach in locally advanced stages. For recurrent or metastatic CC, the combination of chemotherapy plus bevacizumab is the preferred therapy. Immunotherapy approach based on checkpoint inhibitors is evolving as the election therapy following failure to platinum therapy.
