Kan udøve forbedring af immunosenescens og derved reducere tilbagefald hos patienter med hoved og hals kræft

Cancer patients have theoretically returned to a disease-free state after receiving curative anticancer therapy, but even after receiving adjuvant concurrent chemoradiotherapy, it does not ideally prevent all cancer recurrences. For that, several guidelines recommend that cancer survivors participate in regular exercise. Exercise has been thought to be associated with improved outcomes and mortality in healthy individuals as well as in certain cancer populations. However, while the most robust evidence has been demonstrated in patients with prostate, breast and colorectal cancers, the effectiveness of exercise interventions in Head and Neck cancer survivors remains inadequately understood.

Aging of the immune system (so-called immunosenescence) has long been known to increase the risk of infection, cancer, chronic inflammatory diseases and age-related multi-morbidity in humans. In the literature, patients with oral cavity cancer are also believed to have the phenomenon of immune aging (immunosenescence). One of the mechanisms that maintain cellular homeostasis and prevent immunosenescence-related damage is autophagy, a cell-survival mechanism, and it has been proposed as one of the most powerful antiaging therapies. Regular exercise can reestablish autophagy, probably through AMP-activated protein kinase activation, and help in reducing the age-related senescence diseases. At present, many research teams in cancer centers are trying to design large-scale prospective trials to answer whether the intervention of exercise can avoid cancer occurrence, health promotion in survivors, and prevention of recurrence.

This project focuses on the integration of the basic and clinical research. The multidisciplinary research team consists of members from the Department of Hematology and Oncology and Department of Rehabilitation of the New Taipei City Tucheng Hospital and Linkou Chang Gung Memorial Hospital. The main purpose of this three-year project is to investigate whether high-intensity interval training (HIIT) along with resistance exercise intervention, which could reduce the recurrence rate by ameliorating immunosenescence on patients with head and neck cancer. The main tasks order by year of this project are as the following: (1) investigating the differences of immunosenescence indicators in blood with before and after conducting eight weeks of HIIT along with resistance exercise training for patients with head and neck cancer (1st year plan); (2) recruiting new subjects, gathering the physical activity at home and the cancer recurrence rate for first-year subjects, investigating the differences of immunosenescence indicators and immune indicators in the peripheral blood, and examining the clinical effectiveness of exercise training (2nd year plan); (3) Tracking the clinical data and research materials for subjects recruited during the first and second years (3rd year plan). Through the implementation of this three-year project, investigators expect to find a safe and effective exercise prescription for patients with oral cancer after surgery. The findings will provide promising evidence and add further support to the concept that exercise prescription is worth implementation as part of care for the patients with head and neck cancer.
