Objective To analyze the relation between the marital status of patients with colorectal cancer and neoadjuvant therapy (NAT) regimen decision-making and outcomes in the current version of the Database from Colorectal Cancer (DACCA). Methods The version of DACCA selected for this analysis was updated on June 29, 2022. The patients were enrolled according to the established screening criteria and then assigned to 5 groups: the unmarried, married, divorced, remarried and widowed groups. The differences in the NAT regimen decision-making and changes of symptom, imaging, and cancer markers in these 5 groups were analyzed. Results A total of 3 053 data that met the screened criteria were enrolled. The results of statistical analysis reflected that the difference in the constituent ratio of patients chosen NAT strategies among 5 groups was obviously statistically significant (χ2=27.944, P=0.004), showing that remarried patients were inclined to adopt combined target drug. No statistical differences were found in changes of symptom (H=5.717, P=0.221), image (H=8.551, P=0.073), and cancer markers (H=11.351, P=0.183) of the 5 groups after NAT. Conclusion Through analysis of DACCA data, it is found that in the selection of NAT strategy for colorectal cancer, more married and remarried patients tended to choose chemotherapy combined target drug regimen.
ObjectiveTo analyze the relation between the marital status of patients with colorectal cancer and surgical treatment options decision-making and outcomes in the current version of the Database from Colorectal Cancer (DACCA). MethodsThe version of DACCA selected for this analysis was updated on August 31, 2022. The patients were enrolled according to the established screening criteria and then assigned to 3 groups: the unmarried, married, and divorced or widowed groups. The differences in the surgical modality decisions, surgical quality, and surgical complications among these 3 groups were analyzed. ResultsA total of 7 634 data that met the screened criteria were enrolled. It was found that the difference in the composition of the willingness to conserve anus among patients with different marital status was statistically significant (χ2=28.635, P<0.001), reflecting that the willingness to conserve anus was “strong” among unmarried and married patients, and the overall willingness to conserve anus was relatively more positive among unmarried patients, while the willingness to conserve anus was “rational” among widowed or divorced patients. No statistical differences were found in the surgical modality decisions (rectal surgery: χ2=0.493, P=0.782; colon surgery: χ2=0.213, P=0.899), including the presence of prophylactic stoma for the patient with radical resection (χ2=5.156, P=0.076）, surgical quality (H=3.452, P=0.178）, presence of surgical in-hospital complications (χ2=1.663, P=0.435), and the presence of short-term surgical complications (χ2=1.695, P=0.428). ConclusionsAnalysis of the data in DACCA reveals that there is difference in willingness to preserve anus among colorectal cancer patients with different marital status. Married and unmarried patients have stronger anal preservation intention, suggesting that clinical care and family support should be strengthened during clinical diagnosis and treatment.
ObjectiveTo analyze the relation between marital status and prognosis of patients with colorectal cancer (CRC) in the Database from Colorectal Cancer (DACCA). MethodsThe DACCA version selected for this data analysis was updated on January 13, 2023. The data items analysis included the age, gender, marital status, tumor location, tumor property, pathological TNM (pTNM) stage, survival status, and survival time. According to the marital status, the patients were assigned into five marital statuses: the first marriage, unmarried, divorced, remarriage, and widowed groups. The overall survival (OS) and disease specific survival (DSS) of the 5 marital statuses were analyzed, and then the risk factors affecting OS and DSS were analyzed by the Cox proportional hazards regression model. ResultsA total of 7 373 data were obtained from the DACCA according to the screening conditions, of which 6 696 (90.8%) were first marriage, 108 (1.5%) were unmarried, 198 (2.7%) were divorced, 22 (0.3%) were remarriage, and 349 (4.7%) were widowed. The OS and DSS curves had no statistical differences among the CRC patients with 5 marital statuses (χ2=2.692, P=0.611; χ2=2.927, P=0.570). The 3-year cumulative overall survival rate and disease specific survival rate among the 5 marital status patients had statistical differences among the patients with five marital statuses (χ2=24.65, P<0.001; χ2=18.63, P=0.001), further pairwise comparison showed that the 3-year cumulative overall survival rate and disease specific survival rate in the CRC patients with first marriage were higher than those in the widowed patients (Z=3.36, P<0.01; Z=3.02, P<0.01). The multivariate analysis results by the Cox proportional hazards regression model did not find the marital status was associated with the OS and DSS (P>0.05). ConclusionsFrom the real-world analysis results of this study, it is found that 3-year cumulative overall survival rate and disease specific survival rate in patients with first marriage are higher as compared with widowed patients. It is necessary to pay more attention to the long-term follow-up of CRC patients in unmarried or widowed status.
ObjectiveTo analyze differences in postoperative pathological stage characteristics of colorectal cancer (CRC) patients with different marital status in Database from Colorectal Cancer (DACCA). MethodsAccording to the established screening conditions, the patients were collected from the updated version of DACCA on January 23, 2023, and then assigned into three categories according to marital status: married, unmarried, widowed or divorced patients. The differences in postoperative pathological staging, peripheral nerve involvement, pathological tumor regression grade (TRG), cancer nodules, and high-risk factors among the CRC patients with different marital statuses were analyzed. ResultsA total of 6 947 data matching the screening criteria were collected, including 113 unmarried patients (1.6%), 6 315 married patients (90.9%), and 519 divorced or widowed patients (7.5%). The analysis results showed that the pathological TNM staging (Ⅰ–Ⅳ staging: H=19.030, P<0.001;Ⅰ+Ⅱ and Ⅲ+Ⅳ staging: χ2=19.124, P<0.001), pathological T staging (H=7.147, P=0.028), and high-risk factors grading (H=10.246, P=0.006) had statistical differences. The trend presented that the proportions of the patients with earlier pathological TNM staging and T staging (Ⅰor T1 staging) in the married patients were the highest among the 3 marital statuses patients, and the proportions of the later staging (Ⅳ or T4 staging) were the lowest in the married patients. The same trend was found in the high-risk factors grading. However, there were no statistical differences in other pathological features such as peripheral nerve involvement, pathological TRG, and cancer nodules among the CRC patients with 3 marital statuses (P>0.05). ConclusionsThrough data analysis in DACCA, it is found that CRC patients with different marital statuses exhibit certain differences in postoperative pathological stage characteristics, especially in terms of pathological TNM staging, pathological T staging, and high-risk factor grading. However, this conclusion needs to be objectively regarded. From a statistical perspective, the samples size of patients with 3 marital statuses in this study is different. In the future, further analysis can be conducted by balancing the samples size on this basis. From a clinical perspective, there may be more influencing factors, so objective analysis should be conducted after eliminating interference factors one by one.
