Study: Daily high-dose aspirin taken for at least 2 years reduces the risk of colorectal cancer but not other cancers in people with Lynch syndrome

Research has shown that daily aspirin use can reduce the risk of colon and other cancers. The Cancer Prevention Program 2 (CaPP2) study looked at the effect of daily aspirin in patients with Lynch syndrome. After 10 years of follow-up, the results showed that taking daily aspirin for two years reduced the frequency of colon cancer in patients with Lynch syndrome, and importantly, did not result in an increase in side-effects or complications. No benefit was seen for other Lynch syndrome-related cancers, including endometrial cancer. (5/17/21)

Update: Cancer disparities: Colorectal cancer in African Americans

The American Association for Cancer Research (AACR) released a 2020 report about cancer disparities among racial and ethnic groups in the United States. In this XRAY review, we highlight data from the report about the burden of colorectal cancer in African Americans, who have the highest rates of diagnosis and death related to the disease among all racial and ethnic groups.

Study: Expanded access to Medicaid coverage under the Affordable Care Act is linked to reduced cancer mortality

In 2014 the Affordable Care Act expanded Medicaid coverage. How did this affect healthcare for cancer patients? This study shows that deaths from breast, colorectal and lung cancer are lower in states that chose to expand Medicaid compared to states that did not. Early diagnosis was linked to lower death rates. This suggests that increased healthcare access may lead to earlier cancer detection and better outcomes, including lower mortality. (3/31/2021)

Study: Body Mass Index (BMI) may affect how well aspirin use protects against colorectal and ovarian cancer

This study looked at the impact of daily aspirin use on the risk for many types of cancers and whether this effect can be modified by risk factors such as obesity, smoking, physical inactivity or a family history of cancer. Daily aspirin use: 

• lowered the risk for colorectal cancer, but this effect was lost as Body Mass Index (BMI) increased.
• lowered the risk of ovarian cancer risk among obese women.
• offered little or no protection against breast, endometrial or advanced prostate cancer.

Study: Immunotherapy drug Keytruda received FDA approval and showed benefit for treatment of colorectal cancer

In June 2020, the FDA approved Keytruda (pembrolizumab) as an initial therapy for advanced colorectal cancer. This approval was based on the results from the KEYNOTE-177 study. In this study, Keytruda was more successful than chemotherapy in delaying progression of certain types of colorectal cancers. (11/25/20)

Study: LGBTQ patients recommend improvements for their cancer care

Very little research has focused on the cancer care experiences of lesbian, gay, bisexual, transgender and queer (LGBTQ) people. This study looks at recommendations from the LGBTQ community for improving their cancer care. (6/20/19)

Article: The importance of racial diversity in clinical trials

This article by journalists Caroline Chen and Riley Wong looks at racial disparities between participation in clinical trials and the population of people with cancer. (11/6/18)

Study: Cancer “vaccine” injected directly into tumors works in mice

Immunotherapy is treatment that uses the immune system to fight cancer. Still in its infancy, it is a promising therapy that is changing how certain cancers are treated. A new study reports that tumors in lab mice were eliminated when they were injected with two immune system-enhancing agents. This new approach is called in situ (at the original site) vaccination because the injections are given directly into the tumors. It worked on several different types of mouse tumors, including lymphomas and breast tumors. This approach may be safer than conventional immunotherapy because it uses very low doses of the agents and it does not require tumors to have particular markers. (02/23/18)

Article: Preimplantation genetic diagnosis and hereditary cancer

Andrew Joseph’s piece for STAT, “A baby with a disease gene or no baby at all: Genetic testing of embryos creates an ethical morass,” focuses on  preimplantation genetic diagnosis (PGD) and the emerging ethical issue in the field of reproductive medicine: What to do when patients seeking to get pregnant select embryos with DNA that could lead to a disease or a disability.  (11/8/17)

Article: Parents face challenges when deciding the best time to tell children that they may be at high risk for cancer

When certain types of cancers run in families, genetic testing can determine whether the cause is hereditary. Genetic testing can help family members understand their cancer risk and make medical decisions to stay healthy. A test result can provide significant insight, but it also creates challenges for parents, because gene mutations that cause hereditary cancers can be passed from mothers and fathers to sons and daughters. People with these mutations must make difficult decisions about when to tell their children that they too may have inherited the mutation. (8/22/2017)
