Background: Sintilimab is a recombinant fully human anti-programmed death 1 (PD-1) monoclonal antibody that blocks the interaction of PD-1 with its ligand. We evaluated the safety and efficacy of sintilimab combined with chemotherapy and targeted therapy in the treatment of advanced malignant tumors.
Methods: We performed a retrospective analysis of the clinical data of patients with advanced malignant tumors treated with sintilimab combined with chemotherapy and targeted therapy admitted to the Third Ward of the Department of Medical Oncology, First Affiliated Hospital of Anhui Medical University, China, from July 2019 to February 2021. The objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and related adverse reactions were analyzed.
Results: A total of 48 patients with advanced malignant tumors treated with sintilimab combined with chemotherapy and targeted therapy. All 48 patients completed 2 courses of treatment, and the ORR and DCR were 20.83% and 81.25%. The median PFS for all patients in this study was 7 months, and the median OS was not yet reached. The median PFS for the first-line and second-line patients was 10 months, and the median OS was not yet reached. The median PFS for third-line and beyond patients was 7 months, and the median OS was 10 months. The differences in PFS and OS were both statistically significant. Adverse events occurred in 24 patients, of which 18 patients had grade I-II adverse events and 6 patients had grade III-IV adverse events.
Conclusions: Sintilimab is an inexpensive PD-1 drug produced in China. Sintilimab combination therapy showed good safety in the treatment of advanced malignant tumors, with increases in the treatment efficacy and DCR for advanced tumors. Because of few adverse reactions and proven efficacy, sintilimab combination therapy can be used as an option for the treatment of advanced malignant tumors.

Preliminary characterisation of the spatial immune and vascular environment in triple negative basal breast carcinomas using multiplex fluorescent immunohistochemistry.

Triple negative breast cancers often contain higher numbers of tumour-infiltrating lymphocytes compared with other breast cancer subtypes, with their number correlating with prolonged survival. Since little is known about tumour-infiltrating lymphocyte trafficking in triple negative breast cancers, we investigated the relationship between tumour-infiltrating lymphocytes and the vascular compartment to better understand the immune tumour microenvironment in this aggressive cancer type. We aimed to identify mechanisms and signaling pathways responsible for immune cell trafficking in triple negative breast cancers, specifically of basal type, that could potentially be manipulated to change such tumours from immune "cold" to "hot" thereby increasing the likelihood of successful immunotherapy in this challenging patient population.

This study presents a novel approach to modeling breast cancer dynamics, one of the most significant health threats to women worldwide. Utilizing a piecewise mathematical framework, we incorporate both deterministic and stochastic elements of cancer progression. The model is divided into three distinct phases: (1) initial growth, characterized by a constant-order Caputo proportional operator (CPC), (2) intermediate growth, modeled by a variable-order CPC, and (3) advanced stages, capturing stochastic fluctuations in cancer cell populations using a stochastic operator.

Rationale: Nasopharyngeal tuberculosis (TB), a rare form of tuberculosis outside the lungs, can affect any organ or tissue in the body. It is difficult to diagnose because of nonspecific symptoms, often leading to delayed confirmation after the initial patient visit. Clinical manifestations such as cervical lymphadenopathy and irregular mucosal surfaces can be challenging to distinguish from nasopharyngeal cancer or malignant lymphoma.

Rationale: Synovial sarcoma (SS) is a rare and highly malignant soft tissue sarcoma. When SS occurs in atypical locations, it can present significant diagnostic challenges. We report a case of paraspinal SS initially misdiagnosed as spinal tuberculosis, highlighting the diagnostic difficulties and the importance of considering SS in the differential diagnosis.

Colorectal cancer is one of the most common malignant tumors in the world, and about 50% of its advanced patients will have liver metastasis. Preoperative assessment of the risk of liver metastasis in patients with colorectal cancer is of great significance for making individualized treatment plans. Traditional imaging examinations and tumor markers have some limitations in predicting the risk of liver metastasis.
