Factors determining the quality of life in patients undergoing radical surgery due to malignant tumors of the rectum

Introduction: Rectal cancer is one of the most common malignancies in developed countries. However, despite the increasingly better preoperative diagnostics, adaptation of surgical techniques to the location and advancement of the tumor, the combination of surgical treatment with neoadjuvant therapy and adjuvant treatment, standardized control tests, Poland still has not obtained satisfactory results regarding long-term survival. In addition, the effects of the therapy often differ significantly from those expected by patients and the doctors treating them. Aim of the study: To evaluate the effects of rectal cancer treatment among patients of the General and Oncological Surgery Clinic of the Pomeranian Medical University in Szczecin. The impact of numerous factors on postoperative quality of life was analyzed. Material and methods: Between 2007 - 2015, 263 radical resection procedures were performed in patients with diagnosed rectal cancer. Retrospectively, based on medical records, a database was created covering a range of clinical data. Information about death dates of some patients was obtained at the Registry Office in Szczecin. A survey supplementing clinical data and standardized quality of life assessment forms (EORTC QLQ - C30 and CR29) were sent to 120 living patients. A telephone conversation was carried out with some patients who did not respond to the surveys. Finally, data from 90 people was collected, which represents 75% of the patients enrolled in the study. Patients quality of life was assessed using EORTC questionnaire evaluation guides. Results: The patients quality of life worsened the most as a result of anorectal dysfunction. Incontinence of gases and stool, urgency and difficulty in defecation were demonstrated primarily in patients undergoing low rectal resection and irradiation. Patients undergoing radiotherapy, as a result of persistent low anterior resection syndrome, were forced to partially or completely withdraw from professional activity and to limit the pursuit of their interests. Their contacts with family, friends and acquaintances have also deteriorated. The presence of the intestinal stoma significantly affected the deterioration of the reception of the body's own image. However, no relation was found between the existence of the fistula and other aspects of the patients everyday life, including functioning in life and social roles. Conclusions: Due to the acceptable postoperative quality of life of patients with fistula and numerous imperfections of sphincter preserving techniques, operations resulting in terminal ostomy should not be considered as an extremity, and in the case of tumors of the lower rectum with unaffected sphincters, they should be considered as alternative methods for low anterior resection
