Antibody–drug conjugates (ADCs) are reshaping the therapeutic approach to advanced gastrointestinal cancers by integrating tumor-specific monoclonal antibodies with potent cytotoxic payloads to improve targeted tumor cell destruction while minimizing systemic exposure. Compared to traditional chemotherapy, trastuzumab deruxtecan has significantly improved objective response rates and overall survival in HER2-positive gastric and gastroesophageal junction tumors after trastuzumab-based therapy. This supports its role as an important second-line or later treatment option. The ongoing advancement of ADCs targeting CLDN18.2, TROP2, and CEACAM5 indicates that this therapeutic category will continue to expand across gastrointestinal neoplasms. Nonetheless, these advancements are accompanied by a specific and clinically significant toxicity profile. Hematologic suppression, gastrointestinal side effects, hepatotoxicity, and notably interstitial lung disease (ILD) are essential consequences that may need inpatient assessment and care. Interstitial lung disease (ILD), although uncommon, may be severe or lethal if not identified immediately and treated swiftly with medication cessation and corticosteroids. In hospitalized patients, distinguishing ADC-related toxicity from infection or disease progression is often difficult owing to overlapping clinical manifestations, requiring meticulous evaluation and interdisciplinary cooperation. As ADCs are integrated into earlier treatment lines and across a broader patient population, hospital systems must evolve to ensure prompt identification, consistent management protocols, and efficient collaboration between oncology and inpatient teams. This study analyzes the mechanisms, clinical effectiveness, and safety profile of ADCs in gastrointestinal oncology, pointing out the importance of institutional preparedness to safely incorporate these medicines into standard clinical practice. These features also align ADC therapy with personalized medicine by emphasizing biomarker-guided patient selection and individualized toxicity monitoring.

Background: The relationship between COVID-19 vaccination and the incidence of myocardial infarction remains a topic of debate. The study aimed to analyze the demographic, clinical, and outcome characteristics of MI patients post-vaccination in India, focusing on differences between Covishield and Covaxin recipients. Methods: The retrospective observational study included 303 MI patients admitted to a tertiary care center. Data were collected on demographics, comorbidities, vaccination status, ICU admissions, and outcomes. The Charlson Comorbidity Index (CCI) was used to assess disease severity. Statistical analyses evaluated the associations between vaccination status, clinical parameters, and mortality. Results: Among the study population, 74.3% were males, and 32.7% were aged 51–60 years, reflecting the typical Indian MI demographic. Covishield was the predominant vaccine received (80.9%), followed by Covaxin (15.2%), and 4.0% were unvaccinated. No significant differences were observed in CCI scores across vaccination groups. However, the mean CCI was significantly higher in deceased patients than in survivors. ICU admission rates were higher in Covishield recipients (53.1%) than in Covaxin recipients (41.3%), but this difference was not statistically significant. Mortality rates were slightly higher in the Covishield group (11.1%) compared to the Covaxin group (8.9%), although this difference wasn't significant. ICU management was associated with better survival rates compared to ward care. Conclusion: The study contributes to the growing body of evidence supporting the cardiovascular safety of COVID-19 vaccines. While vaccination wasn't significantly associated with increased MI risk or mortality, higher comorbidity burdens were linked to worse outcomes.
