The stage of a malignant tumor defines how advanced the malignant process is at the time of diagnosis. In many clinical scenarios it is an indirect measurement of the efficacy of screening interventions used for early detection. We have evaluated changes in the tumor-node-metastasis (TNM) stage of colorectal cancer across a 15-year period.
This was a retrospective study in which all patients who underwent colorectal cancer surgery at the HIMA San Pablo Medical Center in 1988-1990 (period 1) and 2002-2004 (period 2) had their pathological report examined. The TNM stage for all patients was examined by using standard criteria.
A total of 285 patients were evaluated: 108 in period 1 and 177 in period 2. The number of patients > 71 years of age who underwent colon surgery increased (33% vs 46%). An increase in patients with stage one colon cancer was observed in period 2 (30% vs 10%) with a corresponding decrease in stage 2 and 3 (59% vs 83%).
The pathologic and demographic profile of patients with colorectal cancer has changed over 15 years. Patients with colon cancer are younger and have an earlier stage of disease with a decrease in lymph node involvement. Patients with rectal cancer were older and more likely to be men.

    ABSTRACT: Objective: Colorectal cancer (CRC) is among the most common cancers in Puerto Rico. Few studies have correlated clinical and pathological variables with the overall survival of CRC patients in Puerto Rico. We report the clinical and pathological characteristics of patients who underwent surgical resection at a community hospital in Puerto Rico. Methods: Demographic and pathological variables of patients who underwent CRC surgery at Hospital del Maestro from 2006 through 2011 were reviewed. Descriptive statistics (mean, range, and frequency) and the Cox proportional hazards model were used to determine the influence of demographic and pathological variables on survival, after adjusting for age. Results: Two hundred and five CRC pathology reports were reviewed. Adenocarcinoma represented the most common pathology (202/205; 98.5%). Females represented 52% of the population (106/202) while males represented 48% (96/202). The median age was 71 years (30-96). The right colon was the most common site of presentation (49.7%; 100/201). Stage III was the most common stage at presentation. The presence of mucin, perineural or lymphatic invasion and tumor size were not related to decreased survival. Being male, having a higher stage at diagnosis, and having a moderately or poorly differentiated tumor were characteristics related to decreased survival. Conclusion: This study provides information on clinical and pathological variables and their influence on the overall survival of CRC patients at a community hospital in Puerto Rico. Further research must be performed to identify potential disparities and their influence on the prognosis of this patients.
