Showing 1 - 16Treating DCIS: To Escalate or De-escalate?
There is much debate about the necessity of treating women with ductal carcinoma in situ (DCIS) with surgery or radiotherapy.1,2 It is disconcerting to many that patients with DCIS are treated in the same way as are women with early-stage invasive breast cancer. Many patients with DCIS have...
Expect Questions About Increased Cancer Mortality Risk Among Patients Diagnosed With DCIS
A large cohort study1 finding that the risk of dying of breast cancer was increased threefold after a DCIS diagnosis may cause patients diagnosed with DCIS to ask what they can do to reduce that risk. Currently, there is little that most patients can do. “The lifetime risk of death following DCIS...
Focus on Preventing Invasive Recurrence in Women With DCIS Does Not Sufficiently Address Breast Cancer Mortality
A study published recently by Giannakeas et al looked at the risk of death from breast cancer for women diagnosed with ductal carcinoma in situ (DCIS).1 The investigators anticipated that treatment would eliminate the risk of invasive ipsilateral recurrence and prevent subsequent mortality from...
Hormone Replacement Therapy and Breast Cancer Risk After Oophorectomy in BRCA1-Mutation Carriers
In a study reported in JAMA Oncology, Kotsopoulos et al found that use of hormone replacement therapy overall did not increase risk of breast cancer among BRCA1-mutation carriers after prophylactic bilateral salpingo-oophorectomy; however, use of estrogen-progesterone hormone replacement...
4th Annual Basser Global Prize Awarded to Women’s Cancer Geneticist Steven Narod, MD, FRCPC, PhD (hon), FRSC
The Basser Center for BRCA at Penn’s Abramson Cancer Center has announced the recipient of the 2016 Basser Global Prize is cancer geneticist Steven Narod, MD, FRCPC, PhD (hon), FRSC, Director of the Familial Breast Cancer Research Unit and a senior scientist at the Women’s College Hospital in...
Study Suggests Role of Bilateral Oophorectomy in Preventing Premenopausal Breast Cancer in BRCA2- but Not BRCA1-Mutation Carriers
Bilateral oophorectomy was associated with prevention of premenopausal breast cancer in BRCA2- but not BRCA1-mutation carriers, according to a study reported by Kotsopoulos et al in the Journal of the National Cancer Institute. The study included 3,722 women with BRCA mutations in a prospective...
A Closer Look at the Disparities in Breast Cancer Outcome by Race and Ethnicity
The report from Dr. Steven Narod and colleagues recently published in JAMA1 and reviewed in this issue of The ASCO Post adds to the growing evidence regarding observed disparities in breast cancer outcomes by race and ethnicity among women in the United States. Since 1990, breast cancer death rates ...
Racial/Ethnic Differences in Diagnosis of Breast Cancer at Stage I and Subsequent Survival Reflect Biologic Differences
In a study reported in JAMA, Javaid Iqbal, MD, of Women’s College Research Institute, Toronto, and colleagues found racial/ethnic differences in the likelihood of breast cancer diagnosis at stage I and subsequent survival in U.S. breast cancer patients.1 These differences seemed largely to reflect...
Varied Reactions to Study Finding That Preventing Ipsilateral Recurrence Did Not Prevent Death From Breast Cancer
Women diagnosed with ductal carcinoma in situ have a low risk of dying of breast cancer, according to an observational study looking at data from 108,196 women diagnosed with ductal carcinoma in situ between 1988 and 2011.1 The breast cancer–specific mortality rate for these women was 1.1% at 10...
Increased Risk of Death From Breast Cancer for Women With Ductal Carcinoma in Situ vs General Population
In a study reported in JAMA Oncology, Steven A. Narod, MD, FRCPC, of Women’s College Research Institute, Women’s College Hospital, and the University of Toronto, and colleagues found that the risk of breast cancer mortality was elevated in patients with ductal carcinoma in situ compared with the...
Study Evaluates Breast Cancer Mortality in Women With DCIS
In a study reported in JAMA Oncology, Narod et al found that the risk of breast cancer mortality was elevated in some patients with ductal carcinoma in situ compared with the general population, with the risk being higher in younger vs older women and black vs white women. Approximately half of...
Polish Study Shows Inherited PALB2 Mutation Confers Greater Risk and Poorer Outcome of Breast Cancer
In a Polish prospective cohort analysis reported in The Lancet Oncology, Cybulski et al found that PALB2 mutation carriers had increased risk of breast cancer and that those with breast cancer had significantly reduced long-term survival. Study Details In the study, genotyping for two...
Oophorectomy Is Associated With Significantly Reduced Breast Cancer Mortality in Patients With BRCA1 Mutation or Estrogen Receptor–Negative Disease
In a retrospective analysis reported in JAMA Oncology, Metcalfe et al found that oophorectomy in patients with early-stage breast cancer was associated with significantly improved breast cancer survival in women harboring a BRCA1 mutation and in those with estrogen receptor–negative...
Breast Cancer Diagnoses and Survival Outcomes Vary by Race/Ethnicity
Among nearly 375,000 U.S. women diagnosed with invasive breast cancer, the likelihood of diagnosis at an early stage, and survival after stage I diagnosis, varied by race and ethnicity, with much of the difference accounted for by biologic differences, according to a study reported by Iqbal et al...
Large Study Shows Preventive Ovarian Surgery in BRCA1 Mutation Carriers Should Be Performed Early for Greatest Benefit
The findings of a large international prospective study published in the Journal of Clinical Oncology by Finch et al suggest for the first time that women with BRCA1 mutations should have prophylactic oophorectomy by age 35, as waiting until a later age appears to increase the risk of ovarian...
PPM1D Mutations in Circulating White Blood Cells Associated With Risk of Ovarian Cancer, Increased Mortality, and Risk of Breast Cancer
In a brief communication published in the Journal of the National Cancer Institute, Akbari et al reported finding a higher frequency of PPM1D mutations in circulating white blood cells from women with ovarian cancer vs controls, higher mortality associated with the mutation in women with ovarian...
