Twenty-four evaluable extensively pretreated advanced breast cancer patients received a combination of platinum and etoposide. Platinum was given i.v. at the dose of 80 mg/mq at day 1. Etoposide was given at the dose of 120 mg/mq i.v. at day 1, and p.o. at the dose of 200 mg/mq at day 3 and 5. Treatment was repeated every 3 weeks. CR was never obtained. PR was observed in four patients (17%), MR in two, NC in seven and PD in 11 patients. PR plus MR occurred in six patients (25%). Considering the extensive pretreatment of patients, the results seem to indicate that this combination is active and can be included among the possible options in treating chemotherapy refractory advanced breast cancer. Moreover, it deserves further evaluation in an earlier phase of the disease.

This study utilizes single-cell RNA sequencing data to reveal the transcriptomic characteristics of breast cancer and normal epithelial cells. Nine significant cell populations were identified through stringent quality control and batch effect correction. Further classification of breast cancer epithelial cells based on the PAM50 method and clinical subtypes highlighted significant heterogeneity between triple-negative breast cancer (TNBC) and non-triple-negative breast cancer (NTNBC).

In the past few years, three protein molecules-USP53, NPY2R, and DCTN1-AS1-have garnered significant attention in scientific research due to their potential implications in tumor development. Mass spectrometry and proteomics techniques were used to analyze the three-dimensional structure of these protein molecules and predict their active sites and functional domains. The effects of USP53, NPY2R and DCTN1-AS1 on biological behavior of tumor cells were studied by constructing gene knockout and overexpression cell models.

Background: During the COVID-19 pandemic, hospitals were overwhelmed with infected patients, leading to a disruption in the delivery of services. Patients with cancer, including breast cancer, rely on timely treatment, as delays can reduce survival rates. In this study, we investigated delays in treatment and the factors contributing to delays in chemotherapy and radiotherapy for these patients.

Multimodal phototheranostics on the basis of single molecular species shows inexhaustible and vigorous vitality, particularly those emit fluorescence in the second near-infrared window (NIR-II), the construction of such exceptional molecules nonetheless retains formidably challenging. In view of the undiversified molecular skeletons and insufficient phototheranostic outputs of previously reported NIR-II fluorophores, herein, electron acceptor engineering based on heteroatom-inserted rigid-planar pyrazinoquinoxaline was manipulated to fabricate aggregation-induced emission (AIE)-featured NIR-II counterparts with donor-acceptor-donor (D-A-D) architecture. Systematical investigations substantiated that one of those synthesized AIE molecules, namely 4TPQ, incorporating a fused thiophene acceptor, synchronously exhibited high molar absorptivity (ε), NIR-II emission, typical AIE tendency, significant reactive oxygen species (ROS) generation, and high photothermal conversion efficiency.
