Wed, May 29 6:00am · Celebrate World No Tobacco Day -- Learn About the NCI Cancer Center Cessation Initiative at Mayo Clinic

The World Health Organization recognizes Friday, May, 31, as World No Tobacco Day – the perfect time to celebrate Mayo Clinic’s participation in the National Cancer Institute (NCI) Cancer Center Cessation Initiative

Launched in 2017 as part of the NCI Cancer Moonshot program,
the long-term goal of this initiative is to help cancer centers build and
implement sustainable tobacco cessation treatment programs to routinely address
tobacco cessation with cancer patients.

Mayo Clinic joined this initiative in 2018 when the NCI awarded the Nicotine Dependence Center a supplement to the Mayo Clinic Cancer Center’s NCI Cancer Center Support Grant under the leadership of principal investigator David Warner, M.D. Mayo Clinic is now working with 42 other cancer centers across the nation to:

  • Refine electronic medical records and clinical workflows to ensure the systematic identification and documentation of smokers and the routine delivery of evidence-based tobacco cessation treatment services
  • Overcome patient, clinician, clinic, and health system barriers to providing tobacco cessation treatment services
  • Achieve institutional buy-in that treating tobacco use is a component of organizational “Standard of Care”
  • Create mechanisms to sustain tobacco cessation treatment services so that they continue beyond the funding period of the initiative

Armed with best practices gathered from other cancer centers, the Nicotine Dependence Center is working with care providers across Mayo Clinic to design a system for identifying tobacco users and enrolling them in cessation treatment.

Nov 5, 2018 · Early-phase Cancer Clinical Trials (Phase I) Available at Mayo Clinic

The Early Cancer Therapeutics Group at Mayo Clinic offers patients whose cancers haven’t responded to standard chemotherapy or other treatments the opportunity to join an early-phase clinical trial of a potential new treatment.

Early-phase clinical trials (phase I) determine safe dosage levels and safe methods of treatment delivery. A phase I clinical trial might be the first time a cancer drug or treatment is used in people. These clinical trials offer investigational cancer solutions for cancer therapy resistance — trials for patients whose cancers haven’t responded to standard treatments.

The Early Cancer Therapeutics Group provides access to the most current phase I trials available from Mayo Clinic researchers, pharmaceutical companies and the National Cancer Institute. Phase I clinical trials are available at all three Mayo Clinic campuses in Arizona, Florida and Minnesota.

The Early Cancer Therapeutics Group website provides information for patients interested in participating in Mayo Clinic’s early-phase clinical trials (phase I).

Mayo Clinic has a new website through which patients and referring providers can learn about its early-phase clinical trials for cancer. The website provides an overview of services offered by the Early Cancer Therapeutics Group, including details on who can be seen, what patients can expect from a visit to Mayo Clinic, and a list of current Early Cancer Therapeutics clinical trials.

For more information on trials available through the Early Cancer Therapeutics Group, or to refer a patient, please contact the Mayo Clinic Cancer Center Clinical Trials Referral Office at 855-776-0015 (toll-free).

Oct 3, 2018 · Mayo Clinic Awarded Nation's First Hepatobiliary SPORE Grant

The National Cancer Institute (NCI) has awarded Mayo Clinic an $11.5 million grant to fund  a Specialized Program of Research Excellence (SPORE) in hepatobiliary cancer through August 2023.

Mark A. McNiven, Ph.D.

Headed by principal investigators Mark A. McNiven, Ph.D., and Lewis R. Roberts, M.B., Ch.B., Ph.D., the goal of the Mayo Clinic Hepatobiliary SPORE is to make discoveries and translate them into the clinic for the benefit of individuals diagnosed with or at risk of liver cancer and bile duct cancer.

SPORE grants are designed to promote interdisciplinary research and help basic research findings move quickly from the laboratory to patient care. To earn these competitive grants, institutions must demonstrate a high degree of collaboration between top scientists and clinicians and show excellence in translational research projects. The Mayo Clinic Hepatobiliary SPORE brings together researchers with expertise in basic, translational and clinical science from all three Mayo Clinic campuses in Arizona, Florida and Minnesota.

Lewis R. Roberts, M.B., Ch.B., Ph.D.

This is the first time the NCI has funded a SPORE focused on hepatobiliary cancer, which can be particularly deadly. Less than 18 percent of patients diagnosed with liver or bile duct cancer survive five years or more. The NCI estimates there will be 42,220 new cases of these cancers in 2018, representing 2.4 percent of all new cancer cases, but an estimated 30,200 patients diagnosed with these cancers will die in 2018, representing 5 percent of all cancer deaths. A CDC report released in July 2018 indicated that death rates from liver cancer increased by 43 percent for men and 40 percent for women between 2000 and 2016.

The Hepatobiliary SPORE is comprised of four research projects and three scientific cores designed to consolidate and facilitate the expertise required for effective liver and bile duct cancer research.

The four research projects in the Hepatobiliary SPORE are:

  • Project 1: Fibrolamellar Hepatocellular Carcinoma. This project will study critical genes in human hepatic cells to develop the first diagnostic tests and therapeutic treatments for fibrolamellar hepatocellular carcinoma, a rare form of liver cancer in adolescents and young adults. Project Co-leaders:  Sandy Simon, Ph.D. (The Rockefeller University, New York, NY); Mike Torbenson, M.D.
  • Project 2: Therapeutic Inhibition of Fibroblast Growth Factor and YAP Signaling in Cholangiocarcinoma. This project will examine the cellular mechanisms through which cholangiocarcinoma, or bile duct cancer, develops and progresses. The project team proposes that cross-talk between intracellular signaling pathways within individual cancer cells transmits potent cellular signals, resulting in cancer progression. The team will determine if disruption of these signals results in tumor cell death and therapeutic cancer regression. Project Co-leaders: Gregory J. Gores, M.D.; and Mitesh Borad, M.D.
  • Project 3: Inhibition of SCD1 as a Therapeutic Strategy for Hepatocellular Carcinoma. This project will introduce new concepts that reflect the role of autophagy as a survival mechanism that contributes to therapeutic resistance in hepatocellular carcinoma. It will also focus on targeting stearoyl CoA desaturase 1 (SCD1) metabolic perturbations to reduce therapeutic resistance. Project Co-leaders: John A. Copland, III, Ph.D.; and Tushar C. Patel, M.B., Ch.B.
  • Project 4: Combination Vesicular Stomatitis Virus Viroimmunotherapy and Immune Checkpoint Inhibitor Therapy for Hepatocellular Carcinoma. This project will explore novel immunotherapies for hepatocellular carcinoma, assessing the use of an oncolytic virus expressing an immune stimulatory gene in combination with checkpoint inhibitor antibodies. The project team will also engineer a next-generation oncolytic viral platform tailored to the treatment of hepatocellular carcinoma. Project Co-leaders:  Richard G. Vile, Ph.D.; and Mitesh J. Borad, M.D.

The Mayo Clinic Hepatobiliary SPORE will also develop hepatobiliary cancer investigators through two programs:

  • A Career Enhancement Program led by Dr. Roberts will identify, develop and monitor the progress of the most promising investigators for translational research in hepatobiliary cancer.
  • A Developmental Research Program, led by Edward B. Leof, Ph.D., will attract, develop, support, and monitor the most promising and innovative projects that have the greatest potential to be translated into clinically important applications to reduce the morbidity and mortality of hepatobiliary cancer.

“These projects and programs are designed to identify and develop new scientists in liver and bile duct cancer,” says Dr. McNiven. “I’m hoping this SPORE will help encourage people all around the country and the world to continue to come to Mayo for their liver cancer care.”

Three scientific cores will support SPORE research projects and career development programs:

  • An Administrative Core, led by Dr. McNiven and Dr. Roberts, will provide time and fiscal management and maintain continuous communication within the program and with the NCI and other SPOREs.
  • A Biostatistics Core, led by Chen Wang, Ph.D. and Sumithra J. Mandrekar, Ph.D., will provide statistical, bioinformatics, and computational biology collaboration and data management support.
  • A Biospecimen and Pathology Core, led by Dr. Roberts, Dr. Torbenson, and Mark J. Truty, M.D., M.S., will provide accessioning and processing for new biospecimens with annotated clinical data, with a goal of building a world-class biorepository for hepatobiliary cancer specimens.

The Hepatobiliary SPORE is part of the Mayo Clinic Cancer Center’s Gastrointestinal Cancer Program, which aims to develop and pursue innovative science that will lead to practice-changing outcomes that reduce the incidence of gastrointestinal cancers and increase survival.

The Mayo Clinic Cancer Center has five other current NCI SPORE grants in breast cancer, lymphoma (shared with the University of Iowa), multiple myeloma, ovarian cancer and pancreatic cancer. Mayo Clinic also has a brain cancer SPORE operating under a no-cost extension.

Jul 11, 2018 · Mayo Clinic-led Study Finds Breast Cancer Survivors Aren't Getting Recommended Number of Mammograms Post-Surgery

Kathryn Ruddy, M.D., M.P.H.

Breast cancer survivors are not getting the recommended level of post-surgery screening, according to a study published in the May 2018 issue of the Journal of the National Comprehensive Cancer Network (JNCCN).  Contrary to screening recommendations, mammography rates decline over time as women get further out from their breast cancer diagnosis; African-American women in particular were less likely to receive the recommended amount of screening.

The study was led by Kathryn Ruddy, M.D., M.P.H., a Mayo Clinic medical oncologist in Rochester, Minnesota and co-chair of the Mayo Clinic Cancer Center Survivorship Cross-disciplinary Group. Dr. Ruddy is also a member of the National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology Panel for Survivorship.

“The use of regular mammograms to detect a return of breast cancer before any symptoms appear is associated with better overall survival,” said Dr. Ruddy. “Therefore, clinicians need to make sure that their patients are fully aware of the role these annual mammograms play in screening for new breast cancers as well as for local recurrences. Creating and implementing survivorship care plans with clear follow-up instructions may help ensure that more survivors adhere to recommended screening schedules.”

The researchers followed 27,212 patients for a median of 2.9 years after breast cancer surgery (excluding those who had bilateral mastectomy, for whom mammograms are not needed), with 4,790 patients remaining in the study cohort for at least 65 months.

The retrospective analysis used the OptumLabs Data Warehouse, containing claims from privately insured patients and Medicare Advantage enrollees from across the United States. One year out from surgery, they found 13 percent of the survivors had not undergone any breast imaging. The number without a mammogram within the past year rose to 19 percent by five years after surgery.

Only 50 percent of the patients who were followed for at least five years had at least one mammogram each of those five years.

The study also found that African-American breast cancer survivors were less likely than their white counterparts to receive mammograms according to the recommended schedule. This may contribute to higher mortality rates for that population, given that recurrence of cancer in the breast is considered to be a major driver for poor prognosis in African-American women. While the reasons for this disparity aren’t clear, limited access to genetic testing could be a factor.

There are new tools currently in development to help support and encourage adherence to post-treatment screening guidelines, including mobile apps and web-based programs. Further research is needed to explore how variability in reimbursements for imaging tests may impact surveillance testing.
