Implementing and validating a care protocol for older adults with cancer in resource limited settings with a newly developed screening tool

Abstract

Background: Cancer in the aging population presents manifold challenges. In the resource-limited settings of developing countries, concrete steps to optimize care for older adults with cancer are required.

Materials and method: This prospective, observational study was divided in two parts. In the first part, older adults (≥60 years) with a tissue diagnosis of cancer underwent a preliminary, detailed assessment of relevant geriatric domains. The patients were followed up at 4, 12 and 24 weeks, and their survival status was recorded. In the second part a newly developed screening tool, "SCreening of the Older PErson with Cancer", Version1 (SCOPE-C) was validated on patients with similar characteristics.

Results: 419 participants were enrolled in the study. The mean age of the participants was 66.6 ± 6.2 years, 75% had functional impairment, 35% had malnutrition, and 64% had more than one co-morbidity. The median survival time was 22 weeks from the index visit. Male gender, functional decline, cognitive impairment, malnutrition, and treatment modality were found to be independently associated with survival. Individual Scores on the SCOPE-C Version1 scale were correlated with survival status at 24 weeks, and a cutoff score of 64 had a 72.2% sensitivity and 77.3% specificity for better prognosis.

Conclusion: The present study is a comprehensive attempt to assess older adults with cancer with limited resources in a busy health system. A preliminary assessment with a prognostic screening tool may streamline care in resource-limited settings and aid clinicians in making treatment decisions.
