Simultaneous Subtotal Gastrectomy and Right Colectomy for Synchronous Gastric and Colon Cancer: A Case Report

Area of Science:

• Gastroenterology
• Oncology

Background:

• Synchronous gastric and colon cancer are infrequently reported outside East Asia.
• Gastric cancer incidence is declining in the USA, while colorectal cancer remains a leading malignancy.
• Multiple primary malignancies affect an estimated 2%-17% of cancer patients.

Observation:

• A 50-year-old female presented with an eight-month history of generalized abdominal pain.
• Investigations revealed concurrent diagnoses of gastric and colonic malignancy.
• The patient was treated at Hialeah Hospital, USA.

Findings:

• The case details a rare occurrence of synchronous dual malignancy in the stomach and colon.
• This presentation underscores the need for thorough diagnostic evaluation in complex cases.
• The patient's symptoms and diagnostic pathway are described.

Implications:

• Increased clinical suspicion is crucial for diagnosing multiple primary cancers.
• Adherence to appropriate diagnostic procedures is essential for accurate and timely diagnosis.
• This case contributes to the understanding of rare synchronous cancers in a Western population.
