“…[31] The Korean health system provides universal coverage for cancer treatment, but the access to and quality of mental health care and support systems for health and social welfare are still inadequate. [32,33] Our study of the Korean cohort further extends evidence on the long-term mortality impact of postbreast cancer diagnosis depression among 5-year cancer survivors, highlighting the need for screening and treating depression in breast cancer patients, especially in Asian populations where depression may be overlooked and undertreated.…”

Background Depression is common and harmful among breast cancer survivors, but it may be neglected and untreated in non-Western settings. We examined the association of depression after breast cancer diagnosis with long-term mortality risk in a Korean cohort. Methods We used data from the National Health Insurance Service cancer patients cohort database of South Korea. We included women aged 40 or older who were diagnosed with breast cancer between 2007 and 2013, survived at least 5 years, and had no depression history. Depression was defined as hospitalization for more than 2 days due to depression (ICD-10 code F22 or F23) after diagnosis. We assessed all-cause, cancer-specific, and non-cancer-specific mortality by Cox proportional hazards model, adjusting for covariates. Results Among 30,371 women (mean [SD] age, 56.5 [11.4] years), 30,371 had depression. During the 5-year period, 1,904 deaths occurred (33.6 per 1,000 person-years). Depression patients had higher risks of all-cause mortality (adjusted hazard ratio [aHR], 1.38; 95% CI, 1.03–1.86) and non-cancer-specific mortality (aHR, 1.81; 95% CI, 1.14–2.86) compared to non-depression patients with Charlson comorbidity index of 2 or more. Cancer mortality was not significantly different. All-cause mortality was also higher for depression patients aged 65 or older (aHR, 1.96; 95% CI, 1.27–3.03). Conclusions Depression was linked to increased mortality among 5-year breast cancer survivors, especially for non-cancer causes. This study implies the need for depression screening and treatment among breast cancer patients, especially in non-Western settings where depression may be underdiagnosed and undertreated.

“…Since 2016, the number of cancer survivors has exceeded 1.74 million and the survival rate for more than 5 years is highest among the 32 countries belonging to the Organization for Economic Cooperation and Development. 5 Nevertheless, the cancer mortality rate is predicted to increase by 2032. 6 As cancer enters the social and economic development and ageing population, its incidence may increase significantly.…”

IntroductionCancer is a leading cause of death worldwide. In Korea, it is also a major public health problem. Cancer burden may increase significantly due to ageing population and changes in lifestyle. The features of reproductive factors have changed, which include increased age at first childbirth and decreased breastfeeding duration. This study aims to systematically summarise the association between modifiable reproductive factors and cancer incidence and mortality to provide evidence for planning strategies aimed at reducing cancer incidence and mortality in women.Methods and analysisA literature search was performed using the EMBASE, MEDLINE, Cochrane Library and Korean databases such as the Korean Studies Information Service System, Research Information Sharing Service, KoreaMED, Korean Medical Database, National Assembly Library and Korea Institute from their inception to 24 August 2022. We will include cohort studies addressing the associations between at least one of the reproductive factors and the incidence and mortality of all or specific cancers among Korean women. Two reviewers will screen the references, extract the data, and assess the risk of bias independently and in duplicates. Discrepancies will be resolved through discussion or consultation with a third-party reviewer. We will use the Grading of Recommendations, Assessment, Development and Evaluation approach to evaluate the certainty of evidence. We will summarise the findings of the included systematic reviews through quantitative or narrative syntheses and present the summarised findings in tables.Ethics and disseminationEthical approval is not required, since we will use only the published data. We will disseminate the study findings in peer-reviewed publications.PROSPERO registration numberCRD42022356085.
