The effects of chloramine-T (CT) on monoclonal antibody B72.3 were studied with particular reference to Con-A lectin binding. After exposure to chloramine-T concentrations from 0.8 to 4.0 mg/mL (115-574 mol CT/mol B72.3), B.72.3 showed progressive binding to agarose-linked Con-A. This behavior was paralleled by decreasing immunoreactivity and increasing fragmentation and aggregation of B72.3 demonstrated by SDS-PAGE and size exclusion HPLC.

Purpose: This phase II study is designed to evaluate the combination therapy involving suvemcitug and envafolimab with FOLFIRI in microsatellite-stable or mismatch repair-proficient (MSS/pMMR) colorectal cancer (CRC) in the second-line treatment setting.

Methods: This study is a non-randomized, open-label prospective study comprising multiple cohorts (NCT05148195). Here, we only report the data from the CRC cohort.

Treatment options for patients with advanced biliary tract cancer (BTC) are limited. The programmed cell death protein-1 () inhibitors may have synergistic effects with chemotherapy. Therefore, the aim of our study was to provide real-world data on treatment outcomes in BTC patients receiving chemotherapy alone versus a combination of chemotherapy and inhibitors.

Considering the increasing use of immune checkpoint inhibitors in cancer treatment, our aim is to report a rare cutaneous immune-related adverse event induced by PD-1 inhibitor pembrolizumab and provide a brief overview of pembrolizumab-induced subacute cutaneous lupus erythematosus (SCLE) cases in the literature. We report a 67-year-old woman with oropharyngeal squamous cell carcinoma who developed SCLE during treatment with pembrolizumab. After 18 weeks (sixth cycle) of pembrolizumab immunotherapy, a widespread pruritic erythematous rash evaluated as grade 3 immune-related adverse event appeared primarily on the patient's limbs.

Background: When haemolytic anaemia, thrombocytopenia and renal failure are present, a thrombotic microangiopathic (TMA) condition should be suspected. We describe the various differential diagnoses of primary TMA syndromes, their clinical findings, clinical workup and treatment.

Case Presentation: A previously healthy man in his fifties was hospitalised with anaemia, thrombocytopenia, bilirubinaemia and acute renal failure.

Gastric cancer (GC) is the third leading cause of cancer-related deaths worldwide, with gastrectomy being the primary treatment option. Sepsis, a systemic inflammatory response to infection, may influence tumor growth by creating an immunosuppressive environment conducive to cancer cell proliferation and metastasis. Here, the effect of abdominal infection on tumor growth and metastasis was investigated through the implementation of a peritoneal metastasis model and a subcutaneous tumor model.
