Colorectal carcinoma in the young

Area of Science:

• Oncology
• Surgical Oncology
• Gastroenterology

Background:

• Colorectal adenocarcinoma is a significant health concern globally.
• Age is a known factor influencing cancer prognosis, but its specific impact on young colorectal cancer patients requires further elucidation.
• Understanding disparities in tumor characteristics and outcomes between younger and older patient cohorts is crucial for tailored treatment strategies.

Purpose of the Study:

• To compare the clinicopathological features and survival outcomes of young (<40 years) and older (≥40 years) patients diagnosed with colorectal adenocarcinoma.
• To investigate differences in tumor differentiation and staging between these age groups.
• To assess the impact of age on disease-free interval and overall survival following curative resection.

Main Methods:

• Retrospective analysis of 405 patients with colorectal adenocarcinoma treated over five years.
• Patients were stratified into two groups: under 40 years and 40 years or older.
• Comparison of tumor characteristics (Dukes stage, differentiation) and survival data (disease-free interval, overall survival) between the groups.

Main Results:

• Thirty patients (7.4%) were diagnosed with colorectal adenocarcinoma before age 40.
• Younger patients exhibited a higher proportion of advanced stage (C and D) tumors (76.6% vs. 50%) and poorly differentiated tumors (20% vs. 5.5%).
• Despite similar resection rates, young patients showed significantly poorer disease-free interval and overall survival, with a higher recurrence rate in Dukes C patients.

Conclusions:

• Colorectal adenocarcinoma in patients under 40 presents with more aggressive pathological features.
• Younger age is associated with significantly worse survival outcomes and higher recurrence rates, even after curative surgery.
• These findings underscore the need for increased awareness and potentially different management approaches for colorectal cancer in young adults.
