Description of Research

Dr. Antoni’s research interests focus on examining the effects of stressors and stress management interventions on the adaptation to, and physical course of, diseases such as breast cancer, cervical neoplasia, prostate cancer, chronic fatigue syndrome, and human immunodeficiency virus (HIV) infection. He also has examined some of the biobehavioral mechanisms that might explain ways in which stressful events and psychosocial interventions contribute to the adaptation to these diseases. Much of this work specifically examines psychosocial intervening variables (stress appraisal processes, coping behaviors, and social resources) and biological/physiological variables (endocrine and immune system functioning) that may explain the effects of stressors and psychosocial interventions on quality of life and health outcomes in cancer patients undergoing medical treatments. The overarching goal of the Biobehavioral Oncology (BBO) research program that he co-leads is to develop theoretically-driven and empirically-supported psychosocial interventions to use in the primary, secondary, and tertiary prevention of cancer.

For the past three decades, Dr. Antoni has been funded from the NIH/NCI to conduct multiple randomized clinical trials of a group-based cognitive behavioral stress management (CBSM) intervention he developed for women undergoing treatment for breast cancer. Dr. Antoni also directed a National Cancer Institute-funded P50 Center for Psycho-Oncology Research (CPOR), conducting biobehavioral research on the interrelationships between cognition, emotions, biological processes, and physical health through several randomized clinical trials that tested the effects of CBSM intervention on psychosocial and physiological adaptation in populations at high risk for cancer, or those individuals dealing with treatment for breast or prostate cancer. A number of BBO program investigators, including those from the Departments of Microbiology and Immunology, Obstetrics and Gynecology, Psychology, Psychiatry and Behavioral Science, and Medicine, have conducted CPOR pilot studies designed to elaborate on biobehavioral pathways explored in the CPOR parent trials. The CPOR led to several individual NCI-funded R01 and R21 projects by program investigators, and some of the CPOR core laboratories were used in the design of the BioPsychoSocial Oncology Core, a shared resource in the Cancer Center and the Neuroimmunology Laboratory facility that serves BBO investigators.

Most of Dr. Antoni’s research efforts have focused on using information derived from studies that examine the effects of field and laboratory stressors to develop stress reduction interventions that are specifically targeting disease-related biobehavioral pathways, and which are sensitive to the educational levels and cultural characteristics of the target populations. This has resulted in the development of treatment manuals that can be used as a model for conducting intervention research groups. Moreover, this work has led to the development and testing of brief group-based interventions for clinic use, community-based interventions for racial/ethnic minority populations of cancer survivors, and telephone/web-delivered interventions for home-based delivery to patients. This work is unified in investigating the efficacy and underlying biobehavioral mechanisms in explaining the quality of life and health effects of these different approaches. Many of these studies examine behavioral pathways, while biological pathways and inflammatory processes are measured through biochemical and molecular analyses. This program of work also explores the relative effects of these interventions among ethnic/racial minorities to better understand health disparities in morbidity among treated cancer patients and survivors.

Highlights

  • Showed that group-based CBSM improves mood, symptoms, and quality of life; reduces hormonal indicators of stress (serum cortisol), and increases cellular immune system functioning and Th1 cytokine production over a 12-month period in women undergoing treatment for breast cancer. Women undergoing CBSM during primary treatment also showed lower levels of depression up to 5 years later.
  • Demonstrated for the first time that group-based CBSM alters leukocyte transcriptional dynamics in breast cancer patients with decreased expression of pro-inflammatory genes for cytokines (IL-1, IL-6, TNF-), and chemokines (CCL2, CCL3, CCL3L1, tissue remodeling and epithelial-mesenchymal transition (G0S2, LMNA, MMP9, OSM) at 6 and 12-month follow-up. These changes were paralleled by increased expression of Type-I interferon activation genes. Bioinformatics analyses implicated alterations in NFkB and GATA transcripts and in glucocorticoid receptor sensitivity in mediating these changes.
  • Showed that CBSM decreases perceived stress and reduces the odds of progression of cervical neoplasias in women co-infected with HIV and Human Papillomavirus (HPV) as well as improving immune system reconstitution and decreasing HIV viral RNA in other HIV-infected populations.
