Professor of Surgery, University of Arizona
Dr. Robert Krouse is a Surgical Oncologist with the Southern Arizona Veterans Affairs Health Care System, a Comprehensive Member of The University of Arizona Cancer Center, Professor of Surgery with the University of Arizona in Tucson, and Director of Surgical Research at the Tucson VA. He serves on the Executive Committee of the American College of Surgeons Surgical Palliative Care Task Force, whose purpose is to help introduce the precepts and techniques of palliative care to surgical practice and education in the United States and Canada.
Dr. Krouse’s interest in issues for patients with advanced cancer began as an Immunotherapy Fellow at the National Cancer Institute. This interest broadened as a Surgical Oncology Fellow at the City of Hope National Medical Center, where he was mentored in techniques related to Surgical Oncology and Quality of Life research.
In 2004 Dr. Krouse organized and was moderator for an international conference on malignant bowel obstruction (R13 CA110771), with the goal of advancing palliative care research through development of a trial protocol using malignant bowel obstruction as a model. He is recognized internationally as an expert in the palliative surgical treatment of patients with advanced cancer.
Dr. Krouse participates in many research projects, predominantly related to his major interests in gastrointestinal cancers, skin cancers, quality of life, and end of life care. He was the Principal Investigator of a VA Health Sciences Research and Development Award (IIR 02-221) related to the quality of life for patients with intestinal stomas. He is currently Principal Investigator of an ongoing NCI R01 (CA106912) award for long-term cancer survivors with intestinal stomas in a general population setting.
He is also Principal Investigator of a pilot intervention study (R21 CA133337) for new ostomates to test the feasibility, efficiancy and comprehensibility of a self-management care curriculum based on the Chronic Care Model.
Future potential research projects are aimed at developing and testing interventions for ostomy patients, optimal treatment for malignant bowel obstruction, quantitative histology as a prognostic tool for cutaneous squamous cell cancer, and a prevention trial in colon cancer survivors.
Dr. Krouse’s current cancer-related research program encompasses three areas: cancer survivorship, palliative care, and cancer prevention. His years of clinical experience are an added benefit for his collaboration between the University of Arizona/Arizona Cancer Center and the Southern Arizona Veterans Affairs Health Care System. He has a long history with inter-disciplinary research, leading and participating in teams that include surgeons, nursing researchers, epidemiologists, anthropologists, health economists, psychologists, nutritionists, physiologists, basic scientists, and statisticians.
Related to cancer survivorship, Dr. Krouse’s team has had a focus primarily on rectal cancer survivorship and has established a greater understanding of long-term health-related quality of life (HRQOL) issues. They are currently designing interventions to improve the HRQOL for these survivors and their families. As Co-Chair of the SWOG Cancer Survivorship Committee, Dr. Krouse helps initiate and complete national trials related to cancer survivorship issues.
In palliative care, Dr. Krouse’s research focuses on symptom improvement for cancer survivors facing the end of life. He currently leads an AHRQ-funded grant (AHRQ HS021491, Prospective Comparative Effectiveness Trial for Malignant Bowel Obstruction) examining optimal treatment approaches for patients with malignant bowel obstruction. This study has a novel hybrid design in collaboration with SWOG cooperative group. In cancer prevention, their current focus is predominantly related to quantitative histopathology or karyometry for the identification of malignancy and understanding of prognosis.
