  • Title: Vitamin A and tumor recurrence in bladder cancer.
    Author: Michalek AM, Cummings KM, Phelan J.
    Journal: Nutr Cancer; 1987; 9(2-3):143-6. PubMed ID: 3562292.
    Abstract:
    Results are presented from an investigation concerning the effects of vitamin A on tumor recurrence in a group of 102 patients having early-stage bladder cancer. An odd's ratio of 1.34 was found for tumor recurrence between high and low consumers of vitamin A (p greater than 0.05). Moreover, the rate of tumor recurrence per 1,000 person-months at risk was found to be 1.8 times higher among low, relative to high, consumers of vitamin A (p less than 0.05). While these results are encouraging, larger data sets need to be assembled and analyzed before any definitive conclusions can be reached.
