Abstract

Correction to: Supportive Care in Cancer (2024) 32:88. https://doi.org/10.1007/s00520-023-08282-5. During the writing of a PhD thesis, an error was identified in the published article “Biological and psychological predictors of cognitive function in breast cancer patients before surgery”. Due to an R coding error, participants with stage 0 breast cancer were initially removed but were inadvertently reintroduced during later data merging. Consequently, these cases were not excluded from the final analyses as intended. Demographic and clinical characteristics of breast cancer patients compared with the healthy control group (Corrected) Women with breast cancer (N = 112) Healthy controls (N = 67) Age in years (mean, SD) 61.8 (10.7) 60.9 (9.5) 0.57 Currently partnered, N(%) 1 Yes 74 (66.1%) 44 (65.7%) No 33 (29.5%) 19 (28.4%) Education level, N(%) 0.55 Primary 18 (16.1%) 10 (14.9%) Secondary 36 (32.1%) 17 (25.4%) University 53 (47.3%) 37 (55.2%) BMI (mean, SD) 27.7 (5.0) 28.1 (4.8) 0.61 Physical activity, N(%) 0.48 None 17 (15.2%) 12 (17.9%) Once a week 10 (8.9%) 2 (3.0%) Twice a week 16 (14.3%) 10 (14.9%) ≥ 3 times a week 64 (57.1%) 40 (59.7%) Menopause, yes % 88 (78.6%) 56 (83.6%) 0.62 Cortisol (mean, SD) 5.1 (2.1) - - α-amylase (mean, SD) 140.5 (94.8) - - Depressive symptoms (mean, SD) 11.0 (8.5) 8.8 (7.3) 0.08 Anxiety symptoms (mean, SD) 4.1 (3.8) 2.8 (3.3) 0.02* Overall cancer-related stress (mean, SD) 25.5 (14.6) - - Average time since diagnosis (weeks) 3.2 - - Cancer stage, N(%) 0 4 (3.6%) - - I 57 (50.9%) - - II 41 (36.6%) - - III 10 (8.9%) - - HER- 2 positive, N(%) 8 (7.1%) - - Estrogen positive, N(%) 101 (90.2%) - - Progesterone positive, N(%) 80 (71.4%) - - BMI = Body Mass Index; HER- 2 = human epidermal growth factor receptor 2 * = p < 0.05 (two-sided). Two-sample t-tests were performed for continuous variables to compare means between groups, and chi-squared tests were used for categorical variables to test for group differences The original article has been corrected.
