The haemoglobin levels of patients with prostate cancer treated with radical radiotherapy

Abstract

Introduction: The worldwide estimate points to prostate cancer as the second most frequent cancer in men worldwide, where radiotherapy has been an important modality of curative treatment in managing this neoplasia. The prevalence and impact of cancer-related anemia are not widely known, and it may be overlooked or considered clinically significant. It is believed that the outcomes and toxicity of radiotherapy in prostate cancer treatment may be influenced by blood hemoglobin levels. Objective: To evaluate hemoglobin levels in patients with prostate cancer before and after radiotherapy treatment. Methods: Retrospective, longitudinal study of patients diagnosed with malignant prostate neoplasms undergoing external radiotherapy. Hemoglobin levels were measured before radiotherapy and after treatment completion (20-40 days). Anemia was defined by the World Health Organization as men with values less than 13 g/dl. Prostate cancer recurrence risk classification was based on the National Comprehensive Cancer Network risk criteria. Results: Forty patients were evaluated with measurement of Hemoglobin levels before and after radiotherapy treatment. The mean age was 67 years. According to the risk group classification, 4 patients were low-risk (10%), 27 patients were intermediate-risk (67.5%), and 9 patients were high-risk (22.5%). The mean pre-radiotherapy Hemoglobin levels were 13.3 g/dL, and the mean post-radiotherapy Hemoglobin levels were 10.4 g/dL, p < 0.0001. Conclusion: In this study, a reduction in serum Hemoglobin levels was observed after radiotherapy, highlighting the need for better monitoring of these patients.
