The impact of single and multiple occurrences, as well as the sequence of occurrences, of primary gastrointestinal cancer on overall survival: a comprehensive analysis based on the surveillance, epidemiology, and end results database in the United States from 2016 to 2019.

ABSTRACT:

Introduction

Gastrointestinal cancers encompass malignant tumors of multiple digestive system organs in humans. Each type of digestive system cancer also contains different histological types, each of which has a distinct prognosis. The survival time of cancer patients has significantly extended with the development of modern medicine, allowing for primary cancers occurring more than once in a lifetime.

Methods

The study analyzed multiple primary gastrointestinal cancers, including esophagus, stomach, liver, gallbladder, small bowel, colon, rectum, and anus, based on the Surveillance, Epidemiology, and End Results (SEER) database from 2016 to 2019 in the United States. A total of 119,760 cases were included in this study. Each gastrointestinal cancer was analyzed separately
