A newly published study of 524 families with pathogenic PALB2 mutations from around the world, including almost 50 ICARE participants, represents the largest, most comprehensive effort to evaluate cancer risks.1 Results showed increased risks for female breast cancer (53%), ovarian cancer (5%), pancreatic cancer (2-3%), and male breast cancer (1%). Findings did not suggest higher …

A new study of Polish BRCA1 carriers showed that screening through transvaginal ultrasound was not effective or reliable in detecting ovarian cancer early. Consequently, preventive oophorectomy remains the only proven method to lower ovarian cancer risks and increase survival. Check out the article at: https://www.ncbi.nlm.nih.gov/pubmed/31500890. Check out the NCCN ovarian cancer screening recommendations for BRCA1 …

A new published study of 524 families with PALB2 mutations, including our very own ICARE participants, from around the world showed increased risks of female breast, ovarian, pancreatic, and male breast cancer. The level of risk for female breast cancer is enough to recommend cancer risk management. Cancer risk management includes screening or risk-reducing surgery. …

We are excited to share the latest version of the NCCN Genetic/Familial Breast, Ovarian and Pancreatic Guidelines (V1.2020), which were just updated. Some of the changes made include: PALB2 was added as a high penetrance gene (similar to BRCA1, BRCA2, CDH1, PTEN and TP53) It is appropriate to consider risk reducing mastectomy for cancer risk management …

Early detection of pancreatic cancer is tremendously important, given that most patients who develop the disease are diagnosed at a later stage of the disease when it is usually incurable. Although screening through imaging studies has been proposed (i.e., magnetic resonance cholangiopancreatography (MRCP) and/or endoscopic ultrasound),1 data to support this type of screening as an …

A recent study reported on a single blood test, named “CancerSEEK”, which can screen for 8 common types of cancer (ovarian, liver, stomach, pancreas, esophagus, colorectal, lung, and breast) and may help to identify the location at which the cancer started. This test evaluated the blood from over 1000 patients with Stage 1 to 3 …

Several research groups from around the world that have conducted cancer screening among patients with Li-Fraumeni syndrome and a germline TP53 mutation have recently reported on their observations. Specifically, the National Cancer Institute group demonstrated that screening inclusive of rapid total body MRI detected cancers at an early stage,1 similar to findings published through other …

Recently, researchers evaluated the benefit of adding a mammogram to MRI for breast cancer screening among ~2000 women with a BRCA1 or BRCA2 mutation. Results indicated that the addition of mammography to MRI did not substantially raise the chance of detecting breast cancer in the overall group. However, one-third of breast cancer cases diagnosed among …

People with Lynch Syndrome have a non-working Lynch gene (“mutation”), while the other copy of that gene is normal (recognizing that all of these genes come in pairs, with one member of the pair coming from each parent). Over the last few years, there has been an increased realization that some individuals have a mutation …

A recent article sought to develop an approach to cancer risk management among individuals with mutations in newer inherited cancer genes, many of which result in a moderate (rather than ‘high’) cancer risk. Overall, the investigators suggest a framework that takes the age-specific, lifetime, and absolute cancer risks into account for inherited cancer genes where …

Although pancreatic cancer is one of the cancer types seen among individuals with mutations in inherited cancer genes (including BRCA2 and BRCA1), the proportion of individuals with pancreatic cancer who have an inherited cause has remained uncertain. To further clarify the role of BRCA1 and BRCA2 (BRCA), over 300 patients with pancreatic cancer were tested …

Genetic testing for inherited cancer predisposition is typically performed by testing for one condition at a time. However, with the tremendous advances in genetic testing technologies over the last few years, the cost of testing has plummeted. To put this into perspective, the first human genome cost 2-3 billion dollars to sequence and took over …
