Colorectal cancer (CRC) and gastric cancer, ranking as the third and fifth most prevalent global cancers, respectively, have seen increased diagnoses due to advancements in early detection and extended lifespans. Synchronous and metachronous cancers, with a rare incidence, are notable, with CRC being the predominant synchronous occurrence in gastric cancer patients. Screening CRC patients for gastric cancer is debated due to its low incidence, underscoring the crucial role of early diagnosis. Distinguishing between metastatic adenocarcinoma and synchronous tumors is challenging, relying on techniques such as immunohistochemistry. Surgery is the primary treatment for synchronous cancer, with successful single-stage surgeries reported. A case presentation of a 68-year-old female highlights these complexities. The final diagnosis encompassed stage I gastric cancer and stage IV colon cancer, leading to adjuvant chemotherapy. Synchronous gastric cancer and CRC present a unique clinical challenge, necessitating tailored approaches. Collaboration between surgical and oncological teams is crucial for comprehensive treatment planning and optimizing patient outcomes.

Using the hospital frailty risk score to assess oesophago-gastric cancer patient outcomes: a retrospective cohort study.

Department of Upper Gastrointestinal Surgery, Royal Marsden NHS Foundation Trust, London, United Kingdom.
Background: The inclusion of clinical frailty in the assessment of patients planned for major surgery has proven to be an independent predictor of outcome. Since approximately half of all patients in the UK diagnosed with oesophagogastric (OG) cancer are over 75 years of age, assessment of frailty may be important in selection for surgery.
Materials And Methods: This retrospective cohort study applied the Hospital Frailty Risk Score to data obtained from the NHS Secondary Uses Service electronic database for patients aged 75 years or older undergoing oesophagectomy and gastrectomy between April 2017 and March 2020.
PDPN+ cancer-associated fibroblasts enhance gastric cancer angiogenesis via AKT/NF-κB activation and the CCL2-ACKR1 axis.

Cancer-associated fibroblasts (CAFs) are intrinsic components of the tumor microenvironment that promote cancer progression and metastasis. Through an unbiased integrated analysis of gastric tumor grade and stage, we identified a subset of proangiogenic CAFs characterized by high podoplanin (PDPN) expression, which are significantly enriched in metastatic lesions and secrete chemokine (CC-motif) ligand 2 (CCL2). Mechanistically, PDPN(+) CAFs enhance angiogenesis by activating the AKT/NF-κB signaling pathway.

CRACD, an actin polymerization regulator, is often inactivated in gastric cancer, including DGAC. We found that genetic engineering of murine gastric organoids with ablation combined with mutation and loss induced aberrant cell plasticity, hyperproliferation, and hypermucinosis, the features that recapitulate DGAC transcriptional signatures.

Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of systemic cancer therapy. During disinhibiting the antitumor responses of immune system, ICIs may also cause unique immune-related adverse events (irAEs) which could affect any organ. Here, we report a rare case of sintilimab-induced ureteritis/cystitis in a 55-year-old male undergoing neoadjuvant chemo-immunotherapy for gastric cancer.
