Radiation Epidemiology Branch (REB) investigators and collaborators from the Kaiser health maintenance organization have developed a retrospective cohort of about 7,000 breast cancer patients diagnosed since 1991. Contralateral breast cancer: incidence according to ductal or lobular phenotype of the primary There is no apparent increase in risk of developing a contralateral breast cancer according to the primary cancer histology either IDC or ILC. Standard mammographic follow-up does not need to take account of original tumour pathology. The most common of these second cancers is contralateral breast cancer (CBC), which is estimated to occur at a rate of 0.5% per year (3–6). CBCs are often more difficult to treat than the original cancer because of more resistant biology and inability to reuse previous effective therapy due to dose-limiting toxicities (6–8). Contralateral disease was defined as invasive malignancy or ductal carcinoma in situ (DCIS) in the other breast diagnosed either at the same time or at any point following the diagnosis of the original index tumour during the study period. Some more recent studies have suggested that contralateral breast cancer is more frequent amongst those with ILC than in patients with IDC (20.9% versus 11.2%; p<0.0001) 1; however, others found no significant difference in rates of contralateral breast cancer with ILC (11.9%) compared with IDC (11.3%; p=0.86).

Contralateral breast cancer

The most common type of breast cancer is ductal carcinoma, which begins in the cells of the ducts. Breast cancer can also begin in the cells of a lobule and in other tissues of the breast. Find evidence-based information on breast cancer treatment, causes and prevention, genetics, screening, research, and statistics. Purpose Contralateral breast cancer (CBC) is the most frequent new malignancy among women diagnosed with a first breast cancer. Although temporal trends for first breast cancers have been well studied, trends for CBC are not so well established. The increased use of contralateral prophylactic mastectomy (CPM), mainly in women with sporadic breast cancer, shows no sign of abating. Studies have demonstrated that large numbers of women undergoing CPM have misperceptions about the oncologic effects of CPM, 1 including misperceptions about its impact on breast cancer recurrence and overall survival.

MRI detected clinically and mammographically occult breast cancer in the contralateral breast in 30 of 969 women who were enrolled in the study (3.1%). 2017-06-20 2019-09-09 Previous research has shown that polygenic risk scores (PRSs) can be used to stratify women according to their risk of developing primary invasive breast cancer. This study aimed to evaluate the association between a recently validated PRS of 313 germline variants (PRS313) and contralateral breast cancer (CBC) risk.

2019-04-02 A few cases of NF1 patients with contralateral breast cancer have been identified in the literature, and our case highlights an NF1 patient who developed contralateral breast cancer nearly four decades after her initial breast cancer diagnosis. It has been suggested that NF1 patients may be at higher risk of developing contralateral breast cancer. Although 2-20% of breast cancer patients develop a contralateral breast cancer (CBC), prognosis after CBC is still debated.

We hypothesized that this disease pattern is a manifestation Oct 7, 2016 Adjuvant therapy in patients diagnosed with breast cancer is known to stall the development of contralateral disease; however, the magnitude Oct 7, 2016 The study also found that the risk of contralateral disease got progressively lower the longer a woman took hormonal therapy.

It has been suggested that NF1 patients may be at higher risk of developing contralateral breast cancer. 2020-04-17 · Metachronous contralateral breast cancer (CBC) is a second, presumably independent primary tumor (BC2) developed in the contralateral breast after the first breast cancer (BC1). The lifetime risk of a breast cancer (BC) patient developing CBC has been estimated at 2–20%, depending on factors such as family history, prior endocrine treatment, and age at BC1 diagnosis [ 1 – 3 ]. 2014-02-11 · In this analysis, after a diagnosis of breast cancer in the contralateral breast, the mortality rate was increased twofold (hazard ratio 2.17, 95% confidence interval 1.26 to 3.75; P=0.005).
