Background: Immune checkpoint inhibitors (ICIs) in combination with antiangiogenic drugs have shown promising outcomes in the third-line and subsequent treatments of patients with microsatellite stable metastatic colorectal cancer (MSS-mCRC). Radiotherapy (RT) may enhance the antitumor effect of immunotherapy. However, the effect of RT exposure on patients receiving ICIs and targeted therapy remains unclear.

Background: Small bowel adenocarcinoma (SBA) is a rare malignancy with few established chemotherapy options and a dismal prognosis. We investigated the expression of claudin 18.2, nectin-4, human epidermal growth factor receptor 3 (HER3), and programmed death-ligand 1 (PD-L1) in SBA to identify potential antibody drug targets and analyzed associated clinicopathological features and prognosis.

BRAF mutations in colorectal cancer (CRC) comprise three functional classes: Class 1 (V600E) with strong constitutive activation, Class 2 with pathogenic kinase activity lower than Class 1, and Class 3 which paradoxically lacks kinase activity. Non-Class 1 mutations associate with better prognosis, microsatellite stability, distal tumour location and better anti-EGFR response. Analysis of 13 CRC cohorts (n=6,605 tumours) compared Class 1 (n=709, 10.
