Other Advances in Cancer Treatment Among Cancer Patients with Inherited Disease: Lynch Syndrome

Pertaining to metastatic prostate cancer, recently published data reported 8.1% of men with advanced prostate cancer had evidence of mismatch repair (MMR) mutations in their tumors. These types of mutations are frequently seen in tumors among Lynch syndrome patients. In addition, men with this type of tumor had much poorer survival. Tumors with MMR defects …

Basal Cell Cancers May Be a Risk Factor to Predict Inherited Cancer Predisposition

An interesting area of progress to identify individuals with inherited risks included a study of over 13,000 individuals with six or more basal cell cancers (BCC) evaluated through a claims database. Results indicated ~20% of these individuals had a germline mutation in a DNA repair gene, including BRCA1/2, PALB2, and the Lynch syndrome genes, among …

Expansion of Lynch Syndrome Tumor Spectrum Which May Have Treatment Implications

Although the Lynch syndrome tumor spectrum is thought to be limited to cancers of the colorectum, endometrium, ovaries, stomach, and a few other cancer types, a recent article suggested there might be a broader tumor spectrum than previously considered. Furthermore, colorectal and endometrial cancers which develop among Lynch syndrome patients frequently are determined on tumor …

Differences in Breast Cancer Risks Among Women with Lynch Syndrome

Breast cancer risks were recently reported among a sample of 423 women with mutations in one of the Lynch syndrome genes (MLH1, MSH2, MSH6, or PMS2).1 Results indicated that breast cancer risks were substantially higher among those with MSH6 and PMS2 mutations, compared to MLH1 and MSH2 mutations. In fact, breast cancer risk to age …

Refining Cancer Risks Among Individuals with Lynch Syndrome

Over the past year, multiple studies have refined risks and types of cancer among individuals with Lynch syndrome. Through a Scandinavian study, risks for 13 types of cancer (with colorectal cancers being excluded), were reported to be elevated with differences related to gender, age, and the gene in which mutation was present. Incidence rates of …

Advances in New Treatments for Individuals with Lynch Syndrome

A recently published phase II clinical trial investigated the use of a new class of drugs (called PD-1 Inhibitors) in DNA mismatch repair-deficient/ microsatellite instability-high colorectal tumors (which are features seen in the majority of colorectal tumors from individuals with Lynch Syndrome) among patients with metastatic disease.1 Investigators found patients who received two PD-1 Inhibitors …

Emerging FDA Approvals of Immunotherapy Among Patients With Metastatic MSI-H Cancers

Over the last few years, immunotherapy has emerged as an exciting new class of drugs. As early as 2015, immunotherapy through PD-1 Inhibitors among patients with MSI-H colorectal cancers was shown to be of potential benefit.1 As many individuals with Lynch Syndrome have cancers that are MSI-H and mismatch repair deficient, this class of drugs …

A Newly Identified Inherited Colon Cancer Gene: FAN1

There continues to be rapid advances in identifying new genes involved in inherited cancer risk.  An example of yet another recently identified gene is FAN1, in which a nonsense variant (i.e. the premature change or loss of a protein) was identified following exome sequencing in 3 individuals from a family who met clinical criteria for …

The Potential Promise of Immunotherapy Targeted to Those with Bi-Allelic Mutations in Lynch Syndrome Genes

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 …

Practice Guideline Updates for NCCN Genetic/Familial High-Risk Assessment

The National Comprehensive Cancer Network (NCCN) is a network of oncology healthcare providers who work together to develop best practice guidelines for the delivery of cancer care. Given the increasing use of testing for mutations in several inherited cancer genes at one time (called “multi-gene panel testing”), the Breast/Ovarian and Colorectal Panels sought to provide …

What Is the Risk for Ovarian Cancer Among Women with Mutations in Newer Ovarian Cancer Genes?

The most common form of inherited ovarian cancer is due to mutations in the BRCA1 and BRCA2 genes, which are present in 10-15% of women with ovarian cancer and lead to an ovarian cancer risk of up to 44% and 27%, respectively.  Another set of genes known to raise ovarian cancer risks are the mismatch …

More Information About the Inherited Component of Pancreatic Cancer

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 …

A study of over 1800 individuals with a mutation in one of the Lynch Syndrome genes was recently completed to assess whether aspirin and ibuprofen use may reduce colon cancer risk. Results showed that in those who took aspirin or ibuprofen for between 1 month and 4.9 years, the colon cancer risks were lower than …
