Impact of surgical treatment for locally recurrent rectal cancer on the quality of life of patients / 中华胃肠外科杂志

ABSTRACT

Objective: To investigate the impact of surgical treatment on quality of life in patients with locally recurrent rectal cancer (LRRC). Methods: A descriptive case series study was performed. The complete clinical data of 62 patients who met the diagnostic criteria of LRRC and treated by surgical procedures in Huashan Hospital of Fudan University from January 2012 to November 2019 were analyzed retrospectively. All the patients were followed up at least 12 months. Assessments of urinary function, sexual function, mobility function of lower limb and quality of life were documented. Patients with distant metastasis and surgical history of the urinary system were excluded. According to the criteria of Memorial Sloan Kettering Cancer Center (MSKCC), recurrence were divided into central (n=27), anterior (n=20), posterior (n=7), and lateral (n=8) subtypes. Baseline characteristics, surgical procedures and short-term complications were analyzed. International prostate symptom score (IPSS) and grade of voiding dysfunction were used to evaluate the urinary function. Higher score of IPSS and higher grade of voiding dysfunction indicated worse voiding function. Sexual function for both genders was assessed preoperatively and postoperatively. International index of erectile function-5 (IIEF-5) was used for assessment of male patients and higher score indicated better function. Female sexual function index (FSFI) was used in females and higher score indicated better function. Short-form health survey with 36 items (SF-36), yielding an 8-scale profile of functional health (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, emotional health and mental health) was used to evaluate the quality of life. The higher score indicated the better quality of life. Results: All the operations of 62 patients completed successfully and R0 resection rate was 88.7% (55/62). Postoperative surgical complications occurred in 16 cases (25.8%), including 3 patients of Clavien-Dindo classification III. At postoperative 3-month, 42 patients without ileum cystectomy or ureterostomy suffered from different grade of voiding dysfunction. IPSS increased significantly after the surgery (before surgery: 12.36±4.75, after surgery: 18.40±4.77, t=-9.128, P<0.001). There was no significant difference among the subtypes (P>0.05). At postoperative 12-month, IIEF-5 decreased from 14 (0~25) to 9 (0~19) in males (Z=-5.174, P<0.001) and FSFI deceased from 8.4 (2.0-27.0) to 2.0 (2.0-18.4) in females (Z=-3.522, P<0.001). Scores of physical functioning and role-physical decreased significantly [physical functioning: before surgery 70 (35-85), after surgery 65 (30-80), Z=-3.685, P<0.001; role-physical: before surgery 50 (0-50), after surgery 25(0-75), Z=-4.065, P<0.001], while those of social functioning role-emotional and mental health increased significantly after the surgery [social functioning: before surgery 44 (22-78), after surgery 56 (0-89), Z=-3.509, P<0.001; role-emotional: before surgery 17 (0-100), after surgery 33 (0-100), Z=-2.439, P=0.015; mental health: before surgery 40 (36-76), after surgery 52 (24-80), Z=-3.395, P<0.001]. All surgical procedures decreased the voiding function of LRRC patients and the sexual function of male patients (all P<0.01). However, only total pelvic exenteration and posterior pelvic exenteration decreased FSFI in female patients [before surgery: 8.4 (2.0-27.0) after surgery: 2.0 (2.0-18.4), Z=-2.810, P=0.005]. Conclusions: Multi-visceral resection in LRRC patients may damage voiding and sexual function. However, successful and effective surgical treatment can improve the psychosocial health of LRRC patients.
