Summary
Synchronous colorectal cancer incidence is increasing. Preoperative colonoscopy is crucial for identifying multiple tumors, improving patient treatment and outcomes for this growing cancer type.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Colorectal Surgery
Background:
- The incidence of synchronous carcinoma of the colon and rectum is rising globally.
- This condition, where multiple primary tumors exist simultaneously, presents unique diagnostic and therapeutic challenges.
Purpose of the Study:
- To investigate the incidence and characteristics of synchronous colorectal cancer in a patient cohort.
- To evaluate the importance of preoperative diagnostic methods and postoperative surveillance.
Main Methods:
- Retrospective analysis of 410 patients diagnosed with colorectal cancer.
- Surgical approach (subtotal or segmental colectomy) determined by tumor location and number.
- Preoperative colonoscopy utilized for lesion identification.
Main Results:
- Synchronous colorectal cancer was identified in 10 patients (2.4%).
- Patients with synchronous tumors were older (70.5 years) than those with single tumors (67.4 years).
- Surgical strategy varied based on tumor location and number of lesions.
Conclusions:
- The rising incidence of synchronous colorectal cancer underscores the necessity of preoperative colonoscopy for accurate diagnosis and treatment planning.
- Postoperative endoscopic and clinical monitoring is vital to detect missed lesions and manage the disease effectively.
