Hereditary Cancer
Relevance: Medium
Most relevant for: People undergoing pancreatic cancer screening
Study: More research points to the benefits of pancreatic cancer screening
People with a family history of pancreatic cancer or those who have an inherited mutation that increases risk may benefit from yearly pancreatic cancer screening. Yearly screening may lead to early diagnosis and longer survival. (Posted 10/8/24)

Study: Use of cannabis for cancer symptom management
Among people with cancer, interest in the use of cannabis to manage cancer symptoms and treatment side effects is high. The world's leading professional organization of oncologists has published strategies to help adults with cancer and their healthcare providers have open, nonjudgmental discussions about the use of cannabis to manage cancer symptoms.

Most relevant for: People with Lynch syndrome and people with colorectal cancer who may have Lynch syndrome
Study: Colorectal cancer in people with Lynch syndrome can include types of cancer found more typically in people without Lynch syndrome
When people with Lynch syndrome (LS) develop cancer, their tumors typically have a related set of features or biomarkers known as deficient mismatch repair (dMMR) and high microsatellite instability (MSI-High). However, occasionally people with Lynch syndrome have cancers that are proficient in mismatch repair (pMMR or MMR-P) and have microsatellite stability (MSS or MSI-Low) –more like the colorectal cancers found in people without Lynch syndrome. This study shows that 10 percent of people with Lynch syndrome may have these types of cancers. This can change treatment recommendations. (Posted 9/5/24)

Study: Skin cancer among women with an inherited BRCA mutation
Women with an inherited BRCA1 and BRCA2 mutation have an increased risk of various cancers. Study results suggest that although the risk of non-melanoma skin cancer in these women is similar to the risk of the general population, the risk of melanoma skin cancer is slightly increased.

Most relevant for: People with a BRCA1 or BRCA2 mutation who are considering breast MRI screening
Study: Yearly breast MRI screening improves outcomes for women with inherited BRCA mutations
An international research study of yearly breast MRI screening among women with BRCA1 and BRCA2 gene mutations found that BRCA1 carriers who had MRI screenings were less likely to die of breast cancer than those who did not. Additional studies with more BRCA2 mutation carriers are needed to determine if yearly breast MRIs reduce deaths from breast cancer in this group. (Posted 6/24/24)

Most relevant for: People who have had a risk reducing bilateral oophorectomy
Study: Ovary removal reduces risk of death from any cause in people with BRCA mutations
People who test positive for an inherited BRCA1 or BRCA2 mutation can reduce their risk of ovarian cancer by having both ovaries and fallopian tubes removed. A study published in 2024 found an added benefit of this surgery – a lower risk of death from any cause by age 75. (Posted 5/23/24)

Personal Story: Living a full life with Li-Fraumeni syndrome
This XRAY review is about a five-time cancer survivor who has an inherited mutation in the TP53 gene. People with inherited mutations in TP53 have Li-Fraumeni syndrome, which is linked to a very high lifetime risk for many types of cancer. Here we share his inspiring story and provide more information on Li-Fraumeni syndrome. (Posted 4/16/24)

Most relevant for: People diagnosed with cancer who have not yet had genetic testing
Study: Genetic testing among people with cancer can find mutations that may affect treatment and prevention
Despite national guidelines recommending genetic testing, less than 10 percent of eligible patients had genetic testing within two years after their cancer diagnosis. Among those who had testing, 10-30 percent had an inherited mutation that could affect their medical care. (Posted 3/15/2024)

Most relevant for: People diagnosed with advanced prostate cancer
Study: Genes linked to aggressive prostate cancer
Previous research has linked some inherited mutations to prostate cancer risk. This study found a link to additional genes that should be added to prostate cancer gene panel tests. The study also looked at which genes were most closely linked to aggressive prostate cancer that is more likely to spread. (Posted 2/1/24)

Most relevant for: People at increased risk for breast cancer undergoing prophylactic bilateral mastectomy due to an inherited mutation in BRCA1, BRCA2 or PALB2. People with TNBC who still have breast cancer after chemotherapy.
Update: A breast cancer vaccine for people with an inherited BRCA1, BRCA2 or PALB2 mutation
A breast cancer vaccine is showing promise in early clinical trials. Initially, the vaccine was tested in people with triple-negative breast cancer (TNBC) who were at high risk for recurrence. Now the vaccine is being tested to lower breast cancer risk among people with an inherited mutation in BRCA1, BRCA2 or PALB2. It is also being tested in people with triple-negative breast cancer who are at high risk for recurrence and are taking the immunotherapy drug Keytruda (pembrolizumab) after completing chemotherapy.
