Comprehensive Assessment of Head and Neck Cancer Survivors

Overview

Cancer survivorship has dramatically improved within the last four decades and a greater number of Americans are living after cancer diagnosis. An increase in the number of survivors has highlighted the need to investigate the quality of life experienced by these survivors. While Survivorship research has improved our understanding of the challenges faced by some cancer survivors, there is a paucity of research on the functional and cognitive health status of head and neck cancer survivors. The purpose of this study is to evaluate the functional and cognitive changes that occur in head and neck cancer patients as a result of cancer treatment, in an attempt to increase our understanding of the complex interactions between cancer treatment, comorbid health ailments and quality of life.

Cancer is the second leading cause of death in the United States today, accounting for nearly a quarter of total deaths. Due to advancements in cancer management, specifically in the areas of surveillance, early diagnosis, and utilization of evidenced-based therapies, there has been an increase in the number of survivors in the United States. As at 2007, there were over 11 million cancer survivors in the United States and this number is projected to reach 15 million by the end of 2010. Investigations into the quality of life experienced by these survivors have therefore become necessary if these survivors are to be effectively managed through their course of cancer. The increase in the number of cancer survivors has opened up a relatively new avenue of cancer research termed Cancer Survivorship Research. Cancer Survivorship Research seeks to investigate the physical, functional and psychosocial consequences of cancer. Despite advances made in survivorship research, gaps remain in our knowledge concerning the ability of the cancer survivor to reintegrate into life and function at pre-cancer levels. These knowledge-gaps are especially true for head and neck cancer patients as demonstrated by the paucity of studies in the literature evaluating the functional and psychosocial consequences of cancer in this cohort. This is a significant short-coming especially since head and neck cancer patients are at increased risks for adverse consequences due to their advanced age at the time of cancer diagnosis, comorbidity burdens and substantial history of alcohol or tobacco use. This study will evaluate the functional and cognitive changes that occur in head and neck cancer patients as a result of cancer treatment, in an attempt to understand the consequences of cancer treatment on the quality of life experienced by these survivors. Our study will use self-report questionnaires, neurocognitive assessments and novel performance-based assessments to evaluate functional and cognitive health status at two time-points: 1. At Baseline (before any cancer treatment modality) 2. After the first stage of cancer therapy (chemotherapy, radiation or surgery) Assessments to be utilized include the Center for Epidemiologic Studies Depression Scale (CES-D), University of Alabama Life Space Assessment Aids form (LSA Aids), Dysexecutive Questionnaire (DEX), Katz Index of Activities of Daily Living (ADLs), Lawton Index of Instrumental Activities of Daily Living (IADLs), University of Alabama Life Space Assessment (LSA), Short Blessed Test (SBT), Short Physical Performance Battery (SPPB), Adult Comorbidity Evaluation-27 (ACE-27), and the Delis Kaplan Executive Function Scale (DKEFS) - Sorting task, Color Word Interference task, and Trail Making task. Participants will also be assessed using the Executive Function Performance Test (EFPT). The EFPT is a performance-based measure of cognitive function developed at the Program for Occupational Therapy at Washington University School of Medicine that assesses (under direct observation) the amount of assistance needed by participants to complete five basic tasks essential for self-maintenance and independent living. The tasks include hand-washing, cooking, using the telephone, taking medications and paying bills. Head and Neck cancer patients will undergo these comprehensive assessments at each of the two time-points, allowing for the ability to follow changes in function and cognition over the course of cancer therapy. Statistical analyses will be performed with the SAS® software version 9.1.3 to obtain descriptive statistics and to investigate statistically-significant changes in functional and cognitive health status between the time-points evaluated.
