Relationship between Cancer Worry and Stages of Adoption for Breast Cancer Screening among Korean Women.

ABSTRACT: The possibility of developing breast cancer is a concern for all women; however, few studies have examined the relationship between cancer worry and the stages of adoption for breast cancer screening in Korea. Here, we investigated the associations between cancer worry, the stages of adopting breast cancer screening, and socio-demographic factors known to influence screening behaviors.This study was based on the 2013 Korean National Cancer Screening Survey, an annual cross-sectional survey that utilized nationally representative random sampling to investigate cancer screening rates. Data were analyzed from 1,773 randomly selected women aged 40-74 years. Chi-squared tests and multinomial logistic analyses were conducted to determine the associations between cancer worry and the stages of adoption for breast cancer screening and to outline the factors associated with each stage.Korean women were classified into the following stages of adoption for breast cancer screening: pre-contemplation (24.7%), contemplation (13.0%), action/maintenance (50.8%), relapse risk (8.9%), and relapse (2.6%). Women in the action/maintenance stages reported more moderate to higher levels of worry about getting cancer than those in the pre-contemplation stage. Further, age of 40-49 years and having private cancer insurance were associated with women in the action/maintenance stages.Interventions to address breast cancer worry may play an important role in increasing participation and equity in breast cancer screening.

Project description:PurposeWe evaluated the relationship between breast pathologic complete response (BpCR) and axillary pathologic complete response (ApCR) after neoadjuvant chemotherapy (NACT) according to nodal burden at presentation. As the indications for NACT have expanded, clinicians have started clinical trials for the omission of surgery from the treatment plan in patients with excellent responses to NACT. However, the appropriate indications for axillary surgery omission after excellent NACT response remain unclear.MethodsData were collected from patients in the Korean Breast Cancer Society Registry who underwent NACT followed by surgery between 2010 and 2020. We analyzed pathologic axillary nodal positivity after NACT according to BpCR stratified by tumor subtype in patients with cT1-3/N0-2 disease at diagnosis.ResultsA total of 6,597 patients were identified. Regarding cT stage, 528 (9.5%), 3,778 (67.8%), and 1,268 (22.7%) patients had cT1, cT2, and cT3 disease, respectively. Regarding cN stage, 1,539 (27.7%), 2,976 (53.6%), and 1,036 (18.7%) patients had cN0, cN1, and cN2 disease, respectively. BpCR occurred in 21.6% (n = 1,427) of patients, while ApCR and pathologic complete response (ypCR) occurred in 59.7% (n = 3,929) and ypCR 19.4% (n = 1,285) of patients, respectively. The distribution of biologic subtypes included 2,329 (39.3%) patients with hormone receptor (HR)-positive/human epidermal growth factor receptor 2 (HER2)-negative disease, 1,122 (18.9%) with HR-positive/HER2-positive disease, 405 (6.8%) with HR-negative/HER2-positive disease, and 2,072 (35.0%) with triple-negative breast cancer . Among the patients with BpCR, 89.6% (1,122/1,252) had ApCR. Of those with cN0 disease, most (99.0%, 301/304) showed ApCR. Among patients with cN1-2 disease, 86.6% (821/948) had ApCR.ConclusionBpCR was highly correlated with ApCR after NACT. In patients with cN0 and BpCR, the risk of missing axillary nodal metastasis was low after NACT. Further research on axillary surgery omission in patients with cN0 disease is needed.
