National use of total hip arthroplasty among patients with a history of breast, lung, prostate, colon or bladder cancer-an analysis of the Medicare population

Background: Total hip arthroplasty (THA) is a common and growing procedure in the United States. Concomitantly, there has been a rise in patients diagnosed with certain types of malignancies including solid organ ones. Unfortunately there is limited data available in the literature that describes the use of THA in patients who concomitantly have one of these forms of cancer. Because of the limited data available in the literature regarding this topic, the purpose of this study was to analyze the trends in use of THA among patients with the five most common malignancies in the United States, which include breast, lung, prostate, colon and bladder cancer according to the National Cancer Institute (NCI). Methods: We conducted a retrospective review of the entire Medicare patient population to analyze the use of THA in patients with a diagnosis of solid organ malignancy including breast, lung, prostate, colon and bladder cancer. Results: Our analysis of over 14 million patients, demonstrate that THA is not as commonly performed procedure in patients with such diagnoses with a 0.26% prevalence. The mean incidence of THA was 0.29%, 0.17%, 0.31%, 0.33% and 0.36% for patients with breast, lung, prostate, colon and bladder cancer respectively. Conclusions: THA in cancer patients are not frequently performed but the use of this technique has increased significantly in patients with lung, prostate and bladder cancer.
