This study aims to compare the quality of life in patients with rectal cancer between sphincter preservation and permanent colostomy. The present study is a cross-sectional study that was performed on 120 patients (60 cases in the sphincter maintenance group and 60 cases in the permanent colostomy group) who underwent surgery from February 2017 to November 2016. Quality of life assessment was provided with QLQ-C30 and QLQ-CR29 questionnaires. Finally, the collected data were analyzed using SPSS23 software. According to the results of the QLQ-C30 questionnaire, there was no statistically significant difference in patients' quality of life in terms of performance in the study groups (P˃0.05). Symptoms such as nausea, pain, shortness of breath, sleep disturbance, loss of appetite, constipation and economic problems in the study groups were not statistically significant (P˃0.05). But the mean symptoms of fatigue (P=0.038) and diarrhea (P=0.037) were significantly higher in the sphincter maintenance group than the permanent colostomy group. The mean score of patients' quality of life was 53.43 ± 8.40 in the sphincter retention group and 52.23 ± 11.45 in the permanent colostomy group (P = 0.556). According to the results, the quality of life in the two surgical methods of sphincter preservation and permanent colostomy was not statistically significant. Therefore, treatment decisions should be made by informing patients, both based on their preferences and the physician's clinical judgment.
AB0 blood group type has been linked with different types of cancer. For rectal cancer, there isn’t enough data to assess whether such risk exists. We conducted a retrospective study to evaluate the association between ABO blood type and risk of susceptibility to development, progression, or protection against rectal cancer. We analyzed the medical records of 690 patients with rectal cancer from “Prof. Dr. Alexandru Trestioreanu” Oncological Institute of Bucharest during 8 years of follow-up. Data were scraped using Python. For analysis, we used the Chi-square test. The blood group count was A (287, 41.6.%) followed by 0 (250, 36.2%), B (32, 4.6%), and AB (121, 17.5%). There are no differences in the female and male subgroups regarding blood type and the lack of evidence for the null hypothesis rejection was shown using the χ2 test statistic (χ2 = 2.1, d.f. 3, p = 0.55 for males and χ2 = 2.9, d.f. 3, p = 0.4 for females). These findings are consistent with the notion that even if AB0 blood type is a risk factor for many types of cancer, there is no specific association between rectal cancer and blood group type.
