Objective:To investigate the current status of psychosocial adaptation in young and middle-aged patients after colorectal cancer surgery and to explore its influencing factors, providing a basis for the development of targeted interventions.Methods:A total of 200 postoperative young and middle-aged colorectal cancer patients undergoing follow-up at the outpatient department of Shanxi Cancer Hospital from June 2023 to March 2024 were selected by convenience sampling. Data were collected using a general demographic questionnaire, the Self-Report Psychosocial Adjustment to Illness Scale (PAIS-SR), the Family APGAR Index Questionnaire, and the Simplified Ways of Coping Questionnaire (SWCQ). Multiple linear regression analysis was performed to identify factors influencing psychosocial adaptation.Results:A total of 200 questionnaires were distributed, and 191 valid responses were collected, yielding a valid response rate of 95.5%. The total PAIS-SR score of participants was (57.91±23.45). Multiple linear regression analysis revealed that education level, self-perceived economic status, employment status, presence of a stoma, time since surgery, family care, and positive coping style were statistically significant influencing factors ( P<0.05), explaining 46.4% of the variance in psychosocial adaptation. Conclusions:Healthcare providers should pay particular attention to patients with lower educational levels, poor self-perceived economic conditions, unemployment, a stoma, and shorter postoperative duration. Enhancing family care—starting with patient caregivers—and encouraging the use of positive psychological interventions to foster active coping strategies may help improve psychosocial adaptation in young and middle-aged colorectal cancer patients.

OBJECTIVETo observe the proportion change of immune cells in the peripheral blood of patients with rectal cancer after neoadjuvant therapy and to explore the relationship between tumor regression and CD4⁺CD25(High)CD127(low) regularly T cells(Treg cells).

METHODSPatients with rectal cancer who underwent the neoadjuvant therapy before surgery at the Shanxi Cancer Hospital Colorectal Surgery Department from January to December 2013 were prospectively enrolled. These patients were divided into down-staging group and non-down-staging group according to the change of staging in accordance with TNM classification for rectal cancer after neoadjuvant therapy. Flow cytometry was used to analyze the proportions of Treg cells, CD4+T cells, CD8+T cells, NK cells, B cells, and CD4+/CD8+ ratio in the peripheral blood from these patients before and after neoadjuvant therapy.

RESULTSA total of 108 patients were enrolled, including 76 cases in the down staging group and 32 cases in the non-down-staging group. Differences of immune cells proportions between two groups before neoadjuvant therapy were not statistically significant(all P>0.05). In the down-staging group, the proportions of Treg cells, B cells and CD4+/CD8+ ratio were decreased while the proportion of NK cells did not change obviously after the neoadjuvant therapy. Interestingly, in the non-down-staging group, the proportions of B cells and CD4+/CD8+ ratio were decreased while the proportions of Treg cells and NK cells did not change obviously after the neoadjuvant therapy. In addition, after neoadjunvat therapy, the proportion of Treg cells in down-staging group was significantly lower than that in non-down-staging group [(4.4 ± 1.7)% vs. (6.2 ± 1.9)%, P=0.001].

CONCLUSIONFor patients in the down-staging group after neoadjuvant therapy, the proportion of Treg cells in peripheral blood decreases, suggesting that Treg cells may be a valuable biomarker for assessing tumor regression.
