Purpose: Colorectal cancer (CRC) is the third most common cancer in the USA. The objective of this study was to compare quality of life (QoL) across long-term colorectal cancer survivors and unaffected matched controls while adjusting for comorbidities., Methods: The National Cancer Institute (NCI)-funded Colon Cancer Family Registry (CCFR) was used to randomly select and recruit CRC survivors (≥ 5 years from diagnosis) and matched controls for a cross-sectional survey. Nine geographically diverse sites in the USA from the CCFR participated in the study. Telephone interviews were conducted using computer-assisted methods to assess QoL., Results: A total of 403 cases and 401 controls were included in the final sample. Unadjusted comparison revealed no significant difference between CRC survivors and controls with respect to measures of fatigue, social, emotional, functional, and physical well-being. Multivariate logistic regression revealed that case status had a significant negative influence on colorectal cancer-specific QoL measures. Higher comorbidity indices had a significant negative influence on overall QoL regardless of case status., Conclusions: Quality of life among long-term CRC survivors is similar to control subjects, with the exception of worse CRC-specific QoL measures. Higher comorbidity indices were independently associated with poor QoL for both cases and controls., Implications for Cancer Survivors: Survivors and healthcare providers should be aware that long-term QoL is comparable to the general population; however, there is potential that digestive tract-specific issues may persist.

There are no established chemopreventive agents for lung cancer, the leading cause of cancer death in the United States. Prostacyclin levels are low in lung cancer and supplementation prevents lung cancer in preclinical models. We carried out a multicenter double-blind, randomized, phase II placebo-controlled trial of oral iloprost in current or former smokers with sputum cytologic atypia or endobronchial dysplasia. Bronchoscopy was performed at study entry and after completion of six months of therapy. Within each subject, the results were calculated by using the average score of all biopsies (Avg), the worst biopsy score (Max), and the dysplasia index (DI). Change in Avg was the primary end point, evaluated in all subjects, as well as in current and former smokers. The accrual goal of 152 subjects was reached and 125 completed both bronchoscopies (60/75 iloprost, 65/77 placebo). Treatment groups were well matched for age, tobacco exposure, and baseline histology. Baseline histology was significantly worse for current smokers (Avg 3.0) than former smokers (Avg 2.1). When compared with placebo, former smokers receiving oral iloprost exhibited a significantly greater improvement in Avg (0.41 units better, P = 0.010), in Max (1.10 units better, P = 0.002), and in DI (12.45%, P = 0.006). No histologic improvement occurred in current smokers. Oral iloprost significantly improves endobronchial histology in former smokers and deserves further study to determine if it can prevent the development of lung cancer.
