Purpose: This study was to investigate the efficacy and safety of anlotinib combined with programmed cell death protein 1 (PD-1) blockades for patients with previously treated advanced epithelial ovarian cancer (EOC).
Patients And Methods: Present study was designed as a retrospective study, a total of 32 patients with advanced EOC who progressed after at least two lines previously available standard therapy were included in this study. All the patients were administered with anlotinib combined with PD-1 blockades administration. Clinical activity was implemented and analyzed, which was assessed according to the change of target lesion by imaging evidence and all the subjects were followed up regularly. Safety profile were collected and documented during the treatment. Univariate analysis was carried out using log rank test and multivariate analysis were adjusted by Cox regression analysis.
Results: The best overall response suggested that partial response was noted in 12 patients, stable disease was observed in 14 patients, progressive disease was found in 6 patients. Therefore, the objective response rate (ORR) of the 32 patients was 37.5% (95% CI: 21.1-56.3%), disease control rate (DCR) of the patients was 81.3% (95% CI: 63.6-92.8%). The median follow-up duration of this study was 17.5 months (follow-up range: 0.9-33.5 months). And the median PFS and OS of the 32-patient cohort was 6.8 months (95% CI: 2.64-10.96) and 18.5 months (95% CI: 14.08-22.92), respectively. The most common treatment-related adverse reactions were fatigue (68.8%), nausea and vomiting (56.3%), hypertension (50.0%) and diarrhea (40.6%). Multivariate Cox regression analysis for PFS indicated that ECOG performance status and FIGO stage were independent factors to predict PFS of patients with previously treated EOC.
Conclusion: Anlotinib combined with PD-1 blockades demonstrated promising efficacy and tolerable safety profile for patients with previously treated advanced EOC preliminarily. The conclusion should be confirmed in more patients with advanced EOC subsequently.

Primary small cell neuroendocrine carcinoma of the prostate is extremely rare, highly aggressive, and has a very poor prognosis, with an overall survival typically not exceeding one year. Standard treatment is generally based on the regimen for small cell lung cancer (SCLC), with guidelines recommending etoposide combined with cisplatin (EP regimen) as the first-line treatment. However, their therapeutic effects are limited.

Pulmonary giant cell carcinoma (PGCC) is a rare subtype of non-small cell lung cancer (NSCLC) characterized by complex pathology, high rates of misdiagnosis or missed diagnosis, an aggressive clinical course, rapid progression, and poor prognosis. This case report describes a 67-year-old Chinese male with a left upper lobe lung mass, diagnosed CT-guided lung biopsy as PGCC with symptomatic multiple cerebral metastases. The tumor showed strong PD-L1 positivity, and genetic testing revealed a TP53 exon 4 c.

Background: The study is to evaluate the efficacy and safety of combined anlotinib and EGFR-tyrosine kinase inhibitors (TKIs) in patients with advanced non-small cell lung cancer (NSCLC) who had gradual, oligo, or potential progression after previous EGFR-TKIs treatment.
Methods: We conducted an open-label, single-arm, multicenter, phase II trial in China. Eligible patients were 18-75 years old with histologically or cytologically confirmed NSCLC who were EGFR mutation positive and showed gradual, oligo, or potential progression after EGFR-TKIs.

Anti-angiogenesis offers an important treatment strategy for metastatic breast cancer (MBC). Metronomic chemotherapy (MCT) provides antiangiogenic effects without increased toxicities, making it good partner for antiangiogenic therapy. We conducted the present retrospective study to evaluate the efficacy and safety of anlotinib plus MCT for HER2 negative MBC.

Purpose: Endocrine therapy combined with cyclin-dependent kinase (CDK) 4/6 inhibitors (CDK4/6i) is the preferred treatment for hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer (MBC). However, there are currently no recommendations for therapeutic strategies after progression on CDK4/6i-based treatment. This study aimed to examine the efficacy and safety of anlotinib plus chemotherapy in HR+/HER2- MBC after progression on CDK4/6 inhibitors.
