Colorectal carcinoma in young adults

Area of Science:

• Oncology
• Surgical Oncology
• Gastroenterology

Background:

• Colorectal carcinoma is increasingly diagnosed in younger individuals.
• Limited data exists on clinicopathologic features and surgical outcomes in patients under 40.

Purpose of the Study:

• To evaluate clinicopathologic patterns and surgical results in patients with colorectal carcinoma aged 39 or younger.
• To compare outcomes between young patients and an older control group.

Main Methods:

• Retrospective review of surgical case charts from one institution over 13 years.
• Analysis of 570 patients, with a focus on the 57 patients (10%) aged 39 or under.
• Comparison of clinicopathologic data and survival rates between the young cohort and an older control group.

Main Results:

• Younger patients (≤39 years) had a higher proportion of females and more mucinous carcinoma.
• Significantly higher incidences of lymph node involvement, peritoneal dissemination, and advanced Dukes' stage were observed in younger patients.
• The 5-year survival rate was significantly lower in the young group (41%) compared to the control group (55.9%).
• Curative resection rates were similar between the two groups (71.6% vs. 76.3%).

Conclusions:

• Younger patients with colorectal carcinoma present with more aggressive disease characteristics.
• Despite similar rates of curative resection, younger patients experience poorer survival outcomes.
• Emphasizes the critical need for early diagnosis and aggressive surgical management in young individuals diagnosed with colorectal cancer.
