  • Association between educational level of patients with colorectal cancer and decision-making or curative effect of neoadjuvant therapy: a real-world study based on DACCA

    ObjectiveTo analyze the relation between educational level of patients with colorectal cancer (CRC) and decision-making and curative effect of neoadjuvant therapy (NAT) in the current version of the Database from Colorectal Cancer (DACCA). MethodsThe eligible CRC patients were collected from June 29, 2022 updated DACCA according to the screening criteria and were assigned into 4 groups according to their educational level, namely, uneducated, primary educated, secondary educated, and tertiary educated. The differences in NAT decision-making, cancer marker change, symptomatic change, gross change, imaging change, and tumor regression grade (TRG) among the CRC patients with different educational levels were compared. ResultsA total of 2 816 data that met the screening criteria were collected, 138 of whom were uneducated, 777 of whom were primary educated, 1 414 of whom were secondary educated, and 487 of whom were tertiary educated. The analysis results revealed that the difference in the composition ratio of patients choosing NAT regimens by educational level was statistically significant (χ2=30.937, P<0.001), which was reflected that the composition ratio of choosing a simple chemotherapy regimen in the uneducated CRC patients was highest, while which of choosing combined targeted therapy regimen in the tertiary educated CRC patients was highest. In terms of treatment outcomes, the composition ratios of changes in cancer markers (H=4.795, P=0.187), symptoms (H=1.722, P=0.632), gross (H=2.524, P=0.471), imaging (H=2.843, P=0.416), and TRG (H=2.346, P=0.504) had no statistical differences. ConclusionsThrough data analysis in DACCA, it is found that the educational level of patients with CRC can affect the choice of NAT scheme. However, it is not found that the educational level is related to the changes in the curative effect of patients with CRC before and after NAT, and further analysis is needed to determine the reasons for this.

  • Relation between residence and surgical characteristics of patients with colorectal cancer: a real-world study based on DACCA

    ObjectiveTo analyze the impact of the residence of patients with colorectal cancer (CRC) on surgical characteristics in the current version Database from Colorectal Cancer (DACCA). MethodsAccording to the established screening conditions, the patients with CRC were collected from the updated version of DACCA on January 23, 2023. The analysis indicators enrolled in this study included: the grouping indicator was residence, the surgical characteristic indicators included the surgical timing, surgical nature, expanded resection, intersphincteric resection (ISR) type, patient’s willingness of preserving the anus, and whether preserving the anus. The patients were categorized into three groups based on the residence: inside Chengdu City, outside Chengdu City within Sichuan Province, and outside Sichuan Province. The surgical characteristic indicators of patients with CRC from different residences were comparatively analyzed. ResultsA total of 6 832 analyzable data rows were enrolled. The results of statistical analysis revealed the following findings: there were no statistical differences in the surgery timing and surgery nature among the patients with colon cancer or rectal cancer from the different residences (Surgery timing: H=1.665, P=0.435; H=4.153, P=0.125. Surgery nature: χ2=1.586, P=0.453; χ2=0.990, P=0.610); For the patients with rectal cancer from the different residences, the distributions of the ISR type (H=0.514, P=0.773), patients’ willingness of preserving the anus (χ2=1.437, P=0.487), and whether preserving the anus (χ2=5.513, P=0.064) had no statistical differences. In addition, although there was no statistical difference in the distribution of expanded resection or not among the patients with rectal cancer in different residences (χ2=2.363, P=0.307), it was found that there was statistical difference in the distribution of enlarged resection or not among the patients with colon cancer in different residences (χ2=17.324, P<0.001). ConclusionsFrom the data analysis in DACCA, there are not statistical differences in surgical characteristic indicators such as surgical timing, surgical nature, ISR type, patients’ willingness of preserving the anus, and whether preserving the anus among patients with colon or rectal cancer from different residences. However, the proportion of underwent expanded surgery in the colon cancer patients who from outside Sichuan Province as compared with inside Sichuan Province is relatively higher, this suggests that surgical difficulty is more difficult for the patients from outside Sichuan Province.
