Objective The aim was to study the human programmed cell death 4 (PDCD4) and p53 as diagnostic and prognostic markers in patients with colorectal cancer (CRC). Background CRC is one of the most common cancers. Novel molecules and pathways continue to emerge in the search for improved therapeutic strategies. Patients and methods A total of 120 patients diagnosed with CRC were included and classified based on stage to group 1 (early-stage patients) and group 2 (advanced-stage patients). Moreover, 60 patients diagnosed with benign colorectal polyps were included as a control group (group 3). P53 and PDCD4 antigen levels were measured at presentation, and their relations to patient demographics and clinical features were estimated. Results For PDCD4, area under the curve was 0.889 at cutoff more than 3 ng/ml, with a diagnostic sensitivity of 85.0% and specificity 93.33%, whereas for P53, area under the curve was 1.000 at cutoff greater than 295 pg/ml, with a sensitivity and specificity of 100%. PDCD4 was significantly elevated in group 1 patients compared with group 2 (mean ± SD: 6.9 ± 3.4 vs 1.6 ± 1), with P value less than 0.001. PDCD4 levels were significantly related to tumor grade in groups 1 and 2 (P = 0.041 and 0.011, respectively). P53 levels were higher among patients in group 1 than group 2 (mean ± SD: 2422 ± 692.5 vs 2392.7 ± 680.3, respectively). P53 levels had statistically significant relation with tumor grade in group 2 patients (P = 0.004). Conclusion Both P53 and PDCD4 had diagnostic value. Elevated PDCD4 levels had a positive prognostic value, whereas elevated P53 levels had a negative prognostic value.
