Effects on annual income changes after radical radiotherapy versus after prostatectomy in patients with localized prostate cancer with a specific employment status: A web-based pilot study.

Abstract

Men with localized prostate cancers are insured for undergoing radical radiotherapy or prostatectomy. However, limited information is available on the influence of cancer treatments on patients' employment status in Japan. Therefore, in this web-based survey, we aimed to compare the effects of post-treatment changes on the annual income of patients with prostate cancer after undergoing radical radiotherapy and prostatectomy and to identify the risk factors associated with the decrease in annual income. We investigated the clinical characteristics and demographics including pre-treatment working status, self-employment, non-regular employment, working for wage or salary, and joblessness of patients with localized prostate cancer. Multivariable logistic regression was performed to analyze the effects of various factors on the change in the annual income of self-employed and non-regularly employed workers. Seventy-eight eligible patients with localized prostate cancer had undergone radiotherapy, and 128 patients had undergone prostatectomy. Among self-employed and non-regularly employed workers, post-treatment income decline rates in those who underwent radiotherapy were smaller but not significant (12% vs. 42%, P = 0.074). Multivariable logistic regression analysis revealed that initial treatment for prostate cancer was the only significant risk factor for the post-treatment income decline among self-employed and non-regularly employed workers. Radiotherapy was associated with a smaller decrease in income (odds ratio, 0.22; 95% confidence interval, 0.052-0.95; P = 0.042). Our novel results implied the effectiveness of radiotherapy in preventing post-treatment income decline among patients with prostate cancer based on specific employment status: self-employed or non-regularly employed.
