Abstract

Background: Rectal cancer is a public health priority. Primary objectives of this study were to evaluate the quality of care for non-metastatic rectal cancer using process and outcome indicators. Delay of management, length of stay and readmission rate, sphincter preservation, morbidity, number of examined lymph nodes, mortality, overall and disease-free survivals were evaluated. Secondary objectives were to estimate the relationship between possible predictive parameters for (1) anastomotic leakage (logistic regression), (2) overall or disease-free survivals (cox regression).Methods: We performed a retrospective study on 312 consecutive patients diagnosed with primary rectal cancer between 2016 and 2019. We focused on the 163 patients treated by surgery for non-metastatic cancer.Results: The treatment began within 33 days (range 0-264) after incidence, resection rate was 67%. Digestive continuity rate in lower, middle and upper rectum was 30%, 87% and 96%. Median of 14 lymph nodes (range 1-46) was analyzed. Length of stay and readmission rate were 11 days (range 3-56) and 4%, respectively. Within 90 postoperative days, clinical anastomotic leakage occurred in 9.2% of cases, major morbidity rate was 17%, mortality 1.2%. Multivariate analysis revealed that stoma decreased the risk of anastomotic leakage [hazard ratio: 0.16; 95% confidence intervals: 0.04-0.63; p = 0.008]. The 5-year overall survival after surgery was 85 ± 4%, disease-free survival 83 ± 4%. Patients with major complications, male gender and R1/R2 resection margin had a poorer prognosis.Conclusion: This work showed encouraging results in rectal cancer treatment in our institution, our results were in line with recommendations at the time.
