Self-reported paresthesias, Raynaud’s phenomena, tinnitus, and hearing impairment in a large cohort of long-term testicular cancer (TC) survivors

Abstract

4547 Background: Persisting side-effects of treatment may impair the well-being of TC survivors. The aim of this study was to assess long-term Raynaud’s phenomena, oto-, and neurotoxicity related to prior therapy. Methods: A follow-up survey was conducted in men treated for TC 1980–1994 in Norway. The 1319 eligible responders had a median follow-up time of 11 years (range 4–21) and were allocated to four separate treatment groups: Surgery (Surg), Radiotherapy (Rt), and chemotherapy (Cisplatin [Cis] ≤ 850 mg and Cis > 850 mg). The questionnaire included six items assessing the relevant toxicities. The responders’ scores were dichotomized [minor (“not at all” or “a little”) vs. major (“quite a bit” or “very much”)] and analyzed by logistic regression with Surg as reference. Results: The proportion of cases (%) reporting major symptoms and the corresponding Odds ratios (OR) varied significantly between treatment groups ( table ). Rt was not statistically significantly different from Surg for any symptom, but showed a trend for higher scores of paresthesias in the feet. Cis > 850 mg differed significantly for all symptoms with major symptoms reported by 25–49% with the highest OR (8.1) for Raynaud’s phenomena in hands. Apart from Raynaud’s phenomena, paresthesias in feet were the only symptom significantly different in Cis < 850 mg compared to Surg. Conclusions: Toxicities induced by cisplatin-based chemotherapy persist in many TC survivors. A cold climate may contribute to the high perception of Raynaud’s phenomena in Norwegian TC survivors.
