Abstract
To assess the impact of delay from diagnosis to curative surgery on survival in patients with non-metastatic colon cancer.
National Cancer database (NCDB) analysis (2004-2013) including all consecutive patients diagnosed with stage I-III colon cancer and treated with primary elective curative surgery. Short and long delays were defined as lower and upper quartiles of time from diagnosis to treatment, respectively. Age-, sex-, race-, tumor stage and location-, adjuvant treatment-, comorbidity- and socioeconomic factors-adjusted overall survival (OS) was compared between the two groups (short vs. long delay). A multivariable Cox regression model was used to identify the independent impact of each factor on OS.
Time to treatment was <16 days in the short delay group (31,171 patients) and ≥37 days in the long delay group (29,617 patients). OS was 75.4 vs. 71.9% at 5 years and 56.6 vs. 49.7% at 10 years in short and long delay groups, respectively (both p < 0.0001). Besides demographic (comorbidities, advanced age) and pathological factors (transverse and right-vs. left-sided location, advanced tumor stage, poor differentiation, positive microscopic margins), treatment delay had a significant impact on OS (HR 1.06, 95% CI 1.05-1.07 per 14 day-delay) upon multivariable analysis. The adjusted hazard ratio for death increased continuously with delay times of longer than 30 days, to become significant after a delay of 40 days.
This analysis using a national cancer database revealed a significant impact on OS when surgeries for resectable colon cancer were delayed beyond 40 days from time of diagnosis.
