ABSTRACT

Background and Objectives

Prospective data on presentation and outcomes of colorectal cancer (CRC) in Nigeria are limited; however, emergency presentation with advanced disease is thought common.

Methods

Consecutive CRC patients presenting at six sites over 6 years were included. Risk factors for emergency presentation were evaluated using logistic regression methods. Overall survival (OS) was compared between emergent and elective patients using Kaplan-Meier methods and the log-rank test.

Results

Of 535 patients, 30.7% presented emergently. Median age was 56 years, 55% were men, and 5.0% reported a cancer family history. Emergency patients had more proximal cancers (42.1% vs. 24.0%), Stage IV disease (61.6% vs. 40.2%; p < 0.001), lower household income (₦35 000/month vs. ₦50 000/month), lower education levels (p = 0.008) and accessed care with nonmotorized transport (50.6% vs. 37.2%; p = 0.005). Median OS was shorter in the emergency group (6.4 vs. 17.4 months; p < 0.001). Across clinical stages, emergency presentation was associated with worse OS (Stage IV median OS 4.8 vs. 9.4 months; p = 0.002). Surgery improved survival in both groups, although emergency patients had higher 30-day postoperative mortality (23.2% vs. 9.1%; p < 0.001).

Conclusions

Emergent Nigerian CRC patients have worse OS than elective patients. Cancer control efforts should focus on faster cancer detection, early presentation, diagnosis, and treatment.
