Factors influencing cost, length of hospital stay and mortality in colorectal cancer.

PURPOSE: Colorectal cancers (CRCs) are the most common cancers in the world after lung and prostate cancer in men and breast and lung cancer in women, and usually occur in the recto-sigmoid region. There are many factors that affect their morbidity and mortality. Some markers have been evaluated to predict disease prognosis. However, a gold standard prognostic biomarker has not yet been found for CRC. In the present study, we aimed to evaluate the factors associated with the duration and cost of hospital stay and mortality.

METHODS

Patients who were admitted to the emergency service and general surgery clinic with abdominal pain, rectal bleeding, weight loss, diminished stool discharge, and ileus were included in this study. Recorded were patient age, gender, comorbid factors, family history, surgical treatment procedure, elective or urgent surgical intervention, bowel cleansing before surgery, pathological stage, neutrophil/lymphocyte ratio (NLR), red cell distribution width (RDW), mean platelet volume (MPV) and CEA, CA 19.9 and hemoglobin levels.

RESULTS

The mean patient age was 61.2±12.4 years. The male/female ratio was 0.596(81/136). Emergency surgery was an independent factor increasing the cost and length of hospital stay (p=0.007 and p=0.018). Additionally, patients >65 years of age had increased length of hospital stay and mortality (p=0.008 and p=0.024, respectively). Anemic patients had 50% higher mortality risk compared with patients with normal hemoglobin levels (p=0.030).

CONCLUSION

Based on our results, anemic patients in the geriatric population who underwent emergency CRC surgery may have higher costs, longer hospital stay and greater mortality rates than other CRC patients.
