This observational study evaluated the effectiveness of nab-paclitaxel versus paclitaxel monotherapy as first-line (1L) treatment for metastatic triple-negative breast cancer (mTNBC). 200 patients from the US Flatiron Health electronic health record-derived database (mTNBC diagnosis, January 2011-October 2016) who received 1L nab-paclitaxel (n = 105) or paclitaxel (n = 95) monotherapy were included. Overall survival and time to next treatment were evaluated. The adjusted overall survival hazard ratio was 0.98 (95% CI: 0.67-1.44), indicating a similar risk of death between groups. Adjusted time to next treatment hazard ratio was 0.89 (95% confidence interval: 0.62-1.29). Nab-paclitaxel and paclitaxel monotherapy showed similar efficacy, suggesting their interchangeability as 1L treatments for mTNBC.

Small cell lung cancer (SCLC) is a highly aggressive form of lung cancer with limited therapeutic options and poor prognosis. In this study, we explored the therapeutic potential of BGJ398, a selective fibroblast growth factor receptor (FGFR) inhibitor, alone and in combination with standard chemotherapy (cisplatin and paclitaxel) in SCLC. High-throughput screening of kinase inhibitors was performed on three SCLC cell lines (NCI-H446, NCI-H69, and NCI-H182), identifying BGJ398 as one of the most potent and selective inhibitors.

Background: In recent years, the incidence of pancreatic cancer has shown an obvious increasing trend worldwide and even causes a greater disease burden to the mankind. Due to the lack of effective early surveillance methods, patients are often in the middle to advanced stages of their disease at the time of detection, thus losing the opportunity for surgery. The currently available chemotherapy regimens are yet to be further improved to prolong patient survival.

Background And Purpose: Chemotherapy-induced peripheral neuropathy (CIPN) is a common dose limiting adverse effect that may be transient or become persistent after the treatment ended. The taxane paclitaxel induces CIPN in 57-83% of patients treated. The neuropathy may debut or progress after the end of treatment (EOT), known as coasting, but little is known about the incidence of this phenomenon.

Background: Uterine clear cell carcinoma (UCCC) is a rare and aggressive subtype of endometrial cancer, often presenting at an advanced stage with poor prognosis. Treatment options for advanced or recurrent UCCC are currently limited, especially after platinum-based chemotherapy has failed.

Case Presentation: We present the case of a 49-year-old female diagnosed with stage IV uterine clear cell carcinoma.

Background: The absolute overall survival (OS) improvement with preoperative chemotherapy or chemoradiotherapy in locally advanced non-small cell lung cancer (NSCLC) patients is controversial and unsatisfactory. We designed this trial to explore the efficacy and safety of perioperative sintilimab plus platinum-based chemotherapy for potentially resectable stage IIIB NSCLC to facilitate further optimization of this therapeutic strategy.

Methods: Patients diagnosed with stage IIIB NSCLC through invasive staging approaches and/or PET/CT scans and evaluated as having a high probability of radical resection of the primary lesion and metastatic lymph nodes with clear pathological margins by a multidisciplinary team were enrolled in this open-label, single-arm, phase II trial at a single centre in China.
