Article Abstract

Objective: To investigate the real-world efficacy and toxicity of paclitaxel-cisplatin-bevacizumab and identify prognostic factors for paclitaxel-cisplatin-bevacizumab in platinum-naïve primary stage IVB cervical cancer.

Materials And Methods: We retrospectively reviewed patients with stage IVB cervical cancer who received paclitaxel-cisplatin-bevacizumab as first-line treatment between July 2015 and December 2021 at Asan Medical Center, Korea. Patient data including clinicopathologic characteristics, imaging, paclitaxel-cisplatin-bevacizumab administration, recurrence, and survival were collected.

Results: Overall, 61 patients were included in this study. The median age of the patients was 56 (range, 28-79) years. Patients received a median of 9 (range, 2-30) cycles of paclitaxel-cisplatin-bevacizumab. The most common adverse event (all grades) during treatment was azotemia (80.3 %). Dose reduction and drug interruption were conducted in 41.0 % and 26.2 % of patients, respectively. The median progression-free survival (PFS) and the median overall survival (OS) were 11.8 (95 % confidence interval [CI], 9.3-14.2) and 24.3 (95 % CI, 16.9-31.7) months, respectively. Multivariate analysis indicated that cervical mass size reduction rate ≥40 % at the longest diameter was an independent prognostic factor for PFS (adjusted hazard ratio, 0.24; 95 % CI, 0.11-0.53; p < 0.001). The median PFS of the patients with cervical mass size reduction rate ≥40 % and <40 % were 13.7 (95 % CI, 10.9-16.5) and 5.9 (95 % CI, 0-12.6) months, respectively (p < 0.001).

Conclusion: Paclitaxel-cisplatin-bevacizumab is effective and tolerable as a first-line treatment for platinum-naïve primary stage IVB cervical cancer. Cervical mass size reduction rate ≥40 % during paclitaxel-cisplatin-bevacizumab treatment might be a potential prognostic factor for PFS in patients with platinum-naïve primary stage IVB cervical cancer.

Purpose: The purpose of this study was to evaluate the risk and prognostic factors of stage IVB cervical cancer with brain metastasis from a population-based database, the Surveillance, Epidemiology and End Results (SEER).

Patients And Methods: Cervical cancer patients initially diagnosed with brain metastasis between 2010 and 2019 were included in this study. The risk factors of developing brain metastasis were evaluated by logistic regression model with corresponding 95% confidence interval (95% CI).

Objective: Neuroendocrine cervical carcinomas are a rare but aggressive malignancy associated with a poor prognosis and there is limited evidence to guide clinical decision-making. Our objective was to evaluate the patterns of practice and clinical outcomes of patients diagnosed with neuroendocrine cervical carcinoma.

Methods: This was a retrospective chart review of patients diagnosed with neuroendocrine cervical carcinoma between 2007 and 2023.

Background: Cancer of unknown primary (CUP) is a challenging malignancy characterized by metastatic tumors with an unidentified primary site, even after extensive pathological and radiographic evaluation. Recent advancements in gene expression profiling and comprehensive genomic profiling (CGP) using next-generation sequencing (NGS) have enabled the identification of potential tissue origins, thereby facilitating personalized treatment strategies. Although most cases of CUP present as adenocarcinomas or poorly differentiated tumors, the treatment remains largely empirical, with limited success from molecularly tailored therapies.

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.

Background: No standard treatment exists for patients with platinum-refractory advanced type B3 thymoma and thymic carcinoma. In the PECATI trial, we sought to assess the antitumour activity and safety of lenvatinib plus pembrolizumab in this population.

Methods: In this single-arm phase 2 trial, we recruited participants from 11 hospitals in France, Italy, and Spain.
