Overview
Carcinoma of the cardia refers to malignancies originating in the upper portion of the stomach that extends into the cardiac region near the esophagus. This condition is often associated with chronic exposure to refluxed gastric contents and is frequently linked to Barrett's esophagus and obesity 1.Diagnosis
Endoscopic biopsy for histopathological confirmation 1.
Imaging studies such as endoscopy with biopsy, CT, or MRI to assess extent and invasion 1.
Assessment of tumor markers (e.g., CEA, CA 19-9) though not specific 1.Management
Neoadjuvant therapy: Chemoradiation before surgery in locally advanced cases 1.
Surgical resection: Total or subtotal gastrectomy with lymphadenectomy for resectable tumors 1.
Adjuvant chemotherapy: Use of regimens like cisplatin-based combinations post-surgery to improve survival 1.Special Populations
Pregnancy: Limited data; management typically deferred until postpartum 1.
Pediatrics: Extremely rare; management guided by adult protocols with caution 1.
Elderly: Consider functional status and comorbidities; tailored treatment plans focusing on quality of life 1.
Comorbidities: Presence of Barrett's esophagus or obesity influences risk stratification and management approach 1.Key Recommendations
Endoscopic biopsy is essential for definitive diagnosis of carcinoma of the cardia (Evidence: Strong 1).
Neoadjuvant chemoradiation should be considered for patients with locally advanced disease to improve resectability (Evidence: Moderate 1).
Surgical resection remains the cornerstone of curative treatment for operable cases (Evidence: Strong 1).
Adjuvant chemotherapy post-surgery can enhance survival outcomes, particularly with cisplatin-based regimens (Evidence: Moderate 1).
Management in special populations, including pregnancy and the elderly, should be individualized based on patient-specific factors (Evidence: Expert opinion 1).References
