Background: Anti-angiogenesis therapy has been a vital treatment option in a variety of cancers. Assessing the efficacy and safety of apatinib in patients with heavily pretreated end-stage cancer is essential.
Methods: Thirty patients with end-stage cancer who were heavily pretreated were enrolled in this study. All patients received oral administration of apatinib (125-500 mg/d) between May 2015 and November 2016. Dose reduction or elevation was conducted based on adverse events and doctors' judgments.
Results: Prior to the apatinib treatment, the enrolled patients received a median of 1.2 surgeries (range, 0-7), 1.6 sessions of radiotherapies (range, 0-6), and 10.2 cycles of chemotherapy (range, 0-60); 43.3% of patients had uncontrolled local lesions, 83.3% of patients had uncontrolled multiple metastases, and 30.0% of patients had both. After the treatment, 25 patients had valuable data, 6 (24.0%) patients achieved partial response (PR), and 12 (48.0%) patients had stable disease (SD). The disease control rate (DCR) was 72.0%. The PR and SD rates were 20.0% and 40.0%, respectively, and the DCR was 60.0% in the intent-to-treat (ITT) analysis. Meanwhile, the median progression-free survival (PFS) was 2.6 (range, 0.7-5.4) months, and the median overall survival (OS) was 3.8 (range, 1.0-12.0) months. Furthermore, the PR rate and DCR in patients with squamous cell cancer (SCC) were 45.5% and 81.8%, respectively; those in patients with adenocarcinoma (ADC) were 8.3% and 58.3%, respectively. The adverse events were generally mild. The most common adverse events were hyperbilirubinemia (53.3%), elevated transaminase (36.7%), anemia (30.0%), thrombocytopenia (30.0%), hematuria (30.0%), fatigue (26.7%), and leukopenia (20.0%).
Conclusions: The results of this study demonstrate the efficacy and safety of apatinib and support the further development of apatinib as a potential treatment option for patients with heavily pretreated end-stage cancer.

The Rac1 P29S hotspot mutation in cutaneous melanoma is associated with resistance to MAPK pathway inhibitors (MAPKi) and worse clinical outcomes. Moreover, activation of Rac1 guanine exchange factors (GEFs) also promotes MAPKi-resistance, particularly in undifferentiated melanoma cells. Here we delineate mechanisms of Rac1-driven MAPKi-resistance and identify strategies to inhibit the growth of this class of cutaneous melanomas.

The TROPION-Lung05 phase II trial (ClinicalTrials.gov identifier: NCT04484142) evaluated the safety and clinical activity of Dato-DXd in patients with advanced/metastatic non-small cell lung cancer (NSCLC) with actionable genomic alterations progressing on or after targeted therapy and platinum-based chemotherapy.

Monotherapy with anti-programmed cell death protein 1 (PD-1) monoclonal antibody has been approved for the treatment of advanced non-small cell lung cancer with positive programmed cell death-ligand 1 (PD-L1) expression and oncogene wild type, which revealed survival benefit compared with chemotherapy. Nevertheless, certain patients develop rapid progression on anti-PD-1 inhibitor monotherapy. This novel pattern is called hyperprogressive disease (HPD), and the underlying mechanism and molecular characteristics still leaves not clear.

This study (NCT04728035) aimed to explore the safety and efficacy of liposomal irinotecan (HE072) in patients with metastatic triple-negative breast cancer (mTNBC). This study consisted of two parts. In part 1, the 3 + 3 design was used to investigate three dose levels of HE072 (50, 70 and 90 mg/m).

Background: Radiation segmentectomy (RS) is an alternative potential local curative treatment for selected colorectal liver metastases (CLMs) not amenable to ablation or limited resection.
Purpose: The aim of this study was to evaluate the dosimetric response of low volume CLMs to RS in heavily pretreated patients who are not candidates for resection or percutaneous ablation.
Patients And Methods: This single-center retrospective study evaluated CLMs patients treated with RS (prescribed tumor dose >190 Gy) from 2015 to 2023.
