What are the main findings? Response: Obesity and type 2 diabetes are both known to increase the risk of several cancers. Glucagon-like peptide 1 receptor agonists (GLP-1RAs) have become very popular for both glycemic control and weight loss, but their long-term effects on cancer risk are still unclear. Using a large real-world dataset, we emulated a target trial comparing more than 43,000 GLP-1RA users to matched non-users. We found that GLP-1RA use was associated with a significantly lower overall cancer risk.

What are the main findings? Response: We found that oral bacterial species are linked to a collective 50% increased risk of developing head and neck squamous cell carcinoma (HNSCC). Some of these microbes have previously been shown to contribute to periodontal disease, a serious gum infection that can erode the jawbone and the soft tissues surrounding the teeth.

MedicalResearch.com Interview with: [caption id="attachment_61447" align="alignleft" width="92"]Eric Montminy MDInterventional Endoscopist Cook County Health and Hospitals System Chicago, Illinois Dr. Montminy[/caption] Eric Montminy MD Interventional Endoscopist Cook County Health and Hospitals System Chicago, Illinois   MedicalResearch.com: What is the background for this study? Response: This study was performed in the backdrop of recent colorectal cancer screening guideline updates.  Two national organizations are recommending screening initiation at two different ages: USPSTF recommends initiation at age 45 and the American College of Physicians (ACP) recommends initiation at age 50. With now two national organizations recommending different ages to start screening, patients may become confused (particularly those between 45-50).  Prior confusion has been documented when breast cancer screening recommendations were being changed as well.  Our focus was to examine colorectal adenocarcinoma incidence rates with stage stratification of those who are between the ACP and USPSTF recommendations (ages 46-49). Our study utilized SEER17 data registries over 2000-2020 to collect incidence rates within the U.S.

MedicalResearch.com Interview with: Zai LabRafael Amado, M.D. President, head of Global Oncology Research and Development Zai Lab MedicalResearch.com: What is the background for this study? Response: Zai lab is focused on discovering and developing innovative therapies that will help address medical conditions where there are serious unmet needs. Advanced ovarian cancer, with a low survival and high recurrence rate, is a key focus of our oncology R&D research. In addition to our own discovery program, as part of our open innovation model we partner with companies to license drugs for patients in China and co-develop therapies to address leading causes of cancer death. We currently have a license and collaboration agreement with GSK for the development and commercialization of ZEJULA (niraparib) in mainland China, Hong Kong, and Macau. PRIME was a follow-on study to a previously conducted study called PRIMA, which demonstrated clinical benefit of niraparib in newly diagnosed patients with advanced ovarian cancer regardless of biomarker status. The PRIMA study enrolled a population at high risk of recurrence. Thirty-five percent of patients in PRIMA received an individualized starting dose (ISD) of niraparib based on their baseline weight and platelet count. To further evaluate the efficacy and safety of niraparib with an ISD in a broad population, we decided to conduct the PRIME study. We wanted to explore further whether we could decrease toxicity using an ISD and how it would affect clinical outcomes. The Phase 3 PRIME study was conducted at 29 hospitals in mainland China. PRIME was a randomized, placebo-controlled trial designed to evaluate the efficacy and safety of niraparib at an ISD as first-line maintenance therapy in a broad range of patients with newly diagnosed advanced ovarian cancer. All patients in PRIME received an ISD based on their baseline body weight and platelet count.

  MedicalResearch.com: What is the background for this study? Response: Triple-negative breast cancer (TNBC) accounts for 10% to 20% of all breast cancer diagnoses in the US. This subtype of breast cancer tends to spread faster and has fewer treatment options. In the US, Black women are about two-fold more likely than White women to develop TNBC.

MedicalResearch.com Interview with: Olivier van Not Scientific Bureau, Dutch Institute for Clinical Auditing Leiden, the Netherlands Department of Medical Oncology University Medical Centre Utrecht Utrecht, the Netherlands MedicalResearch.com: What is the background for this study? Response: The introduction of immune checkpoint inhibitors (ICIs) has significantly improved the survival of advanced melanoma patients. Treatment with these ICIs can lead to immune-related adverse events, also known as toxicity. This toxicity is graded from 1 (mild) to 5 (fatal) and examples of these toxicities are hepatitis and colitis. Since these toxicities can be life threatening and become chronic, they require treatment with immunosuppressants such as corticosteroids or anti-TNF. In a previous study of melanoma patients treated with different types of immune checkpoint inhibitors [Verheijden et al, Clin Cancer Research 2020] we found survival to be better for patients experiencing immune-related toxicity, which is in line with many other studies in several cancer types and a recent meta-analysis.
