Abstract
BACKGROUND
The incidence of malignant gastrointestinal (GI) tumors is increasing, and advancements in medical care have significantly improved patient survival rates. As a result, the number of cases involving multiple primary cancers (MPC) has also increased. The rarity of MPC and the absence of sensitive and specific diagnostic markers often lead to missed or incorrect diagnoses. It is, therefore, of vital importance to improve the vigilance of clinicians and the accurate diagnosis of this disease. Patients with GI malignancies face a higher relative risk of developing additional primary malignant tumors compared to those with other systemic tumors. Vigilant monitoring and follow-up are crucial, especially for high-risk groups, which include older adults, men, those with addictions to alcohol and tobacco, those with a family history of tumors, and those who have undergone radiotherapy.
CASE SUMMARY
In this article, we report three cases of MPC, each involving malignant tumors of the GI tract as the initial primary carcinoma, offering insights that may aid in effectively managing similar cases.
CONCLUSION
Patients with GI malignancies face a higher MPC risk. Developing screening and follow-up protocols may enhance detection and treatment outcomes.
Core Tip: Multiple primary cancer (MPC) refers to the presence of two or more distinct primary malignant tumors that arise in either the same organ or multiple separate organs and tissues within a single patient. This article offers a detailing three cases of gastrointestinal malignancies with MPCs. It features a thorough presentation of endoscopic, tomographic, and biopsy images, including both macroscopic and microscopic views. Besides, the article highlights the importance of comprehensive management for patients with MPCs, aiming to raise clinicians' awareness and improve patient outcomes.
