Background: Noninvasive biomarkers that capture the longitudinal multiregional tumour burden in patients with breast cancer may improve the assessment of residual nodal disease and guide axillary surgery. Additionally, a significant barrier to the clinical translation of the current data-driven deep learning model is the lack of interpretability. This study aims to develop and validate an information shared-private (iShape) model to predict axillary pathological complete response in patients with axillary lymph node (ALN)-positive breast cancer receiving neoadjuvant therapy (NAT) by learning common and specific image representations from longitudinal primary tumour and ALN ultrasound images.

Immune molecule diagnostics in colorectal cancer: CCL2 and CXCL11.

Open Life Sci

August 2025

Department of Gastroenterology, Beijing Luhe Hospital, Capital Medical University, Beijing, 101149, China.

Traditional serrated adenomas (TSAs) and sessile serrated adenomas (SSAs) are known precursors to colorectal cancer (CRC), but differentiating between them morphologically can be challenging. This study developed an immune molecule-based model to distinguish TSA from SSA using RNA sequencing data from the GEO datasets (GSE117606, GSE45270, GSE117607). Gene expression profiling was conducted with the R package GEOquery, and immune cell infiltration was assessed using CIBERSORTx.

August 2025

Department of Thoracic Surgery I, Yunnan Cancer Center, The Third Affiliated Hospital of Kunming Medical University, Yunnan Cancer Hospital, Peking University Cancer Hospital Yunnan, No 519 Kunzhou Road, Kunming, 650118, China.

Hypertension and lung cancer are two of the most prevalent chronic diseases worldwide, each contributing significantly to public health burdens. While both diseases have been extensively studied individually, their comorbidity remains an underexplored area of research. Recent studies suggest that genetic susceptibility plays a crucial role in the coexistence of these conditions, with overlapping genetic variants influencing both vascular homeostasis and tumorigenesis.

Adjuvant chemotherapy and immune checkpoint blockade exert quite durable anti-tumor responses, but the lack of effective biomarkers limits the therapeutic benefits. Utilizing multi-cohorts of 3,095 patients with gastric cancer, we propose an attention-enhanced residual Swin Transformer network to predict chemotherapy response (main task), and two predicting subtasks (ImmunoScore and periostin [POSTN]) are used as intermediate tasks to improve the model's performance. Furthermore, we assess whether the model can identify which patients would benefit from immunotherapy.

In recent years more and more studies have pointed out that the microbiota plays an important role in the development of gynecological tumors. A healthy female reproductive tract microbiota is dominated by lactobacilli, which can produce lactic acid and other metabolites to protect the normal reproductive tract microenvironment. If the microflora is out of balance, the abnormally increased flora may contribute to inflammation and even cancer in the reproductive system by activating the immune response, regulating metabolites and hormone levels.

The treatment of brain metastases (BMs) from non-small cell lung cancer (NSCLC) is primarily systemic and local; however, the therapeutic effects of various treatment methods on BMs are minimal. The occurrence of BMs from NSCLC is a complex process. The penetration of tumour cells into the blood-brain barrier changes the function of cell junctions, leading to changes in the microenvironment of intracranial tumours.
