Archive These critical investigations will be essential for the understanding of the etiology of breast cancer. ASCO Author Services 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). Importance: The clinical management of BRCA1 and BRCA2 mutation carriers requires accurate, prospective cancer risk estimates. Among patients receiving no adjuvant therapy, 88% who had an ER-positive PBC and 75% who had an ER-negative PBC developed an ER-positive CBC (P = .11). Chi-square tests were undertaken to examine the differences in contralateral rates for both registries and univariate analysis to ascertain which predictors affected contralateral breast cancer … The most common second cancer in breast cancer survivors is another breast cancer.

Conquer Cancer Foundation JCO Oncology Practice Although rare, it is very clinically relevant, as lymph node metastasis is the most important prognostic factor in breast cancer. If applied to CBC, this theory could support the notion that CBC may represent a metastatic lesion that has developed in the primed contralateral breast where the necessary homeostatic factors are present. One of the fundamental goals for assessment of ER in any breast tumor is treatment selection. Tamoxifen improves survival of women with ER-positive breast cancers but does not improve survival of women with ER-negative tumors.21 Also, the risk of CBC is reduced by 45% after 5 years of tamoxifen therapy,21 and incidence of invasive cancer decreased by 49% with primary tamoxifen chemoprevention.9 A majority of the patients in the current report, in the absence of adjuvant therapy, were diagnosed with an ER-positive CBC regardless of the hormone receptor status of the PBC.

J Clin Oncol 17:: Anderson WF, Chatterjee N, Ershler WB, et al: Estrogen receptor breast cancer phenotypes in the Surveillance, Epidemiology, and End Results database. This is a provocative question, which cannot be answered by our current limited knowledge of the biology of these contralateral cancers. This differentiation has implications for the development of drug resistance and subsequent systemic treatment of the CBC. Contralateral breast cancer uncommon among women with ductal carcinoma in situ Fewer than 6% of women with ductal carcinoma in situ developed contralateral breast cancer within 10 years, … Patients' … Enter words / phrases / DOI / ISBN / authors / keywords / etc. We aimed to evaluate whether postdiagnosis use of COX-2 selective or other nonaspirin nonsteroidal anti-inflammatory drugs (NSAIDs) reduce the risk of contralateral breast cancer (CBC) among Danish breast cancer … The authors conclude that women with advanced-stage primary breast cancer have a heightened risk of developing contralateral breast cancer. 23, no. Before this can be accomplished, a more precise characterization and definition of CBC must be attained. With increasing cure rates comes increasing concern about their long-term health. Purpose The Women’s Environmental Cancer and Radiation Epidemiology (WECARE) study demonstrated the importance of breast cancer family history on contralateral breast cancer (CBC) … J Clin Oncol 23:: Swain SM, Wilson JW, Mamounas EP, et al: Estrogen receptor status of primary breast cancer is predictive of estrogen receptor status of contralateral breast cancer. The cumulative risk for contralateral breast cancer 25 years after first breast cancer was 47.4% (95% CI, 38.8% to 56.0%) for patients from families with BRCA1 or BRCA2 mutations. Analyses are underway to evaluate the relationship among radiotherapy, newer hormonal therapies, chemotherapy agents, and obesity in survivors. However, is it really important to make the distinction of a new primary or metastases? Differences among study populations may have led to disparate results from previous studies. published online before print Contralateral breast cancer (CBC) is today treated as a new primary tumor, independent of the first breast cancer (BC1). The actuarial risk of contralateral breast cancer was 29.5% at 10 years. Contact Us Published online J Clin Oncol 14:: Early Breast Cancer Trialists' Collaborative Group: Tamoxifen for early breast cancer: An overview of the randomised trials.

The ASCO Post We aimed to … WECARE: The Women’s Environment, Cancer And Radiation Epidemiology Study One in eight women will develop a primary breast cancer during her lifetime and 5-10% of these women will subsequently develop a second primary cancer in the contralateral breast. Contralateral breast cancer (CBC) is the most common second primary cancer in patients diagnosed with breast cancer.1 Patients with a history of breast cancer have an increased risk of developing a second primary breast cancer (PBC), with an annual risk of 0.5% to 1% or a cumulative lifetime risk of 2% to 15%.2 Because breast cancer is the most commonly diagnosed cancer in women in the United States,3 prevention of CBC is a significant clinical issue.

This study aimed to evaluate the association between a recently validated PRS of 313 germline variants (PRS 313) and contralateral breast cancer (CBC) risk. In the study, with a median 6.3 years of follow-up, 274 cases of contralateral breast cancer … Objectives: To estimate age-specific risks of breast, ovarian, and contralateral breast cancer for mutation carriers and to evaluate risk modification by family cancer … By linking electronic treatment files and the Kaiser cancer registries for information on subsequent cancers, researchers have developed a rich resource for studying the late effects of breast cancer treatments. Natl Cancer Inst Monogr 68:: Adami HO, Bergstrom R, Hansen J: Age at first primary as a determinant of the incidence of bilateral breast cancer: Cumulative and relative risks in a population-based case-control study. ER status was determined using a ligand-binding assay in the current study. Given these conclusions, should we consider prescribing tamoxifen to all patients with a diagnosis of PBC, regardless of receptor status, as a chemopreventive agent for CBC? A lower frequency of ER-positivity is seen as tumors increase in size, implying that ER expression is blocked as tumors grow.11,19 Furthermore, a certain percentage of patients with ER-positive tumors develop ER-negative metastases.20 Thus, the true origins of ER-positive and ER-negative tumors have yet to be elucidated. In situ lesions (2%) made up a minority of the tumors in the patients in the study by Arpino et al6 because they were not routinely sent for hormone receptor assays. In this issue, Arpino et al6 conclude that the hormone receptor status of the PBC does not predict the hormone receptor status of a subsequent CBC in the absence of prior adjuvant therapy. Contralateral breast cancer is the most common second cancer in women with primary breast cancer. It has long been debated whether ER-positive and ER-negative tumors either originate from distinctly different cells or represent a continuum. Cancer 28:: Arpino G, Weiss HL, Clark GM, et al: Hormone receptor status of a contralateral breast cancer is independent of the receptor status of the first primary in patients not receiving adjuvant tamoxifen. Laboratory studies suggest that inhibition of the cyclooxygenase (COX)-2 enzymes inhibits breast cancer development. We sought to … CBCs are often more difficult to treat than the … If considered a new primary tumor, local regional therapy will be followed by systemic therapy as deemed necessary. DOI: 10.1200/JCO.2005.01.910 Journal of Clinical Oncology It is unlikely that the question of whether tamoxifen is beneficial for patients with an ER-negative PBC will ever be answered in a prospective clinical trial because of the low event rate requiring a large number of study patients.

Reviewers Cancer 17:: Lewison EF, Neto AS: Bilateral breast cancer at the Johns Hopkins Hospital: A discussion of the dilemma of contralateral breast cancer. Since its initial proposal, the multistep process has been well accepted as the route by which tumors arise.13 Breast cancers likely emerge from inherited or acquired mutations in stem or early progenitor cells.14 Mammary stem cells have only recently been isolated by identifying tumorigenic cells based on cell-surface marker expression.15 These stem cells represent important targets for mutations because they are slow-dividing, long-lived cells that may be exposed to various damaging agents over time, leading to a series of alterations that ultimately leads to carcinoma.
