Abstract:
Objective:To explore the influence of multidisciplinary treatment (MDT) on clinical staging and diagnosis and treatment strategies for rectal cancer.Methods:A retrospective case series study was conducted. The clinical data of 142 rectal cancer patients who underwent surgical treatment in Shanxi Provincial People's Hospital from March 2021 to December 2021 were retrospectively analyzed. According to whether to implement MDT or not, all patients were divided into MDT group (68 cases) and non-MDT group (74 cases). Relevant clinical data including patients' basic information (gender, age, etc.), TNM staging, whether to receive neoadjuvant radiotherapy and chemotherapy or not, surgical methods, R0 resection rate of both groups were compared. The implementation methods and the effects of MDT for patients were summarized.Results:There were statistically significant differences in the proportion of clinical N staging at initial diagnosis, whether to receive neoadjuvant radiotherapy and chemotherapy or not of both groups (all P < 0.05). The overall agreement rate of clinical T staging at initial diagnosis and pathological T staging was 67.6% (46/68), 50.0% (37/74), respectively in the MDT group and the non-MDT group, and the difference was statistically significant ( χ2 = 4.54, P = 0.033). The overall agreement rate of N staging at initial diagnosis and pathological N staging was 50.0% (34/68), 54.1% (40/74), respectively in the MDT group and the non-MDT group, and the difference was not statistically significant ( χ2 = 0.23, P = 0.629). The treatment rate of neoadjuvant radiotherapy and chemotherapy was 57.4% (39/68) and 4.1% (3/74), respectively in the MDT group and the non-MDT group, and the difference was statistically significant ( χ2 = 48.33, P < 0.001). The R0 resection rate in both the MDT group and non-MDT group was 100.0%, and no tumor tissue was found at the upper, lower, and circumferential margins. Conclusions:MDT could provide more accurate clinical staging and more effective diagnosis and treatment opinions for patients, and provide reliable guidance for the treatment selections.
