Objective: To investigate the efficacy of Bushen Huoxue Decoction (BSHXD) combined with moxibustion on inflammation and urinary symptoms in prostate cancer (PC) patients.
Methods: A total of 87 patients with PC admitted to the Hebei Provincial Hospital of Traditional Chinese Medicine from 08/2019 to 12/2021 were collected for this retrospective study. There were 42 patients treated with conventional treatment regimens who were regarded as the control group (CG). The remaining 45 patients treated with BSHXD and moxibustion were considered the experimental group (EG). The quality of survival of patients was assessed through the C30 and PR25 subscales of the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ). Patients' urinary symptom changes were evaluated using the International Prostate Symptom Score (IPSS). The levels of interleukin-6 (IL-6) and tumor necrosis factor α (TNF)-α were measured by Elisa assay before and after the treatment. The maximum urinary flow rate and residual urine volume of the patients were compared before and after the treatment. Logistic regression was used to analyze the risk factors affecting the progression to castration-resistant prostate cancer (CRPC).
Results: There was no statistical difference in the total response rate between the two groups of patients (P>0.05). Patients in the EG had a higher QLQ-C30 and maximum urinary flow rate scores than those in the CG after the treatment. The residual urine volume, IL-6, TNF-α, QLQ-PR25, and IPSS scores in the EG were lower (P<0.05). The multi-factorial regression analysis revealed that the Gleason score and the pre-treatment prostate-specific antigen (PSA) level were independent risk factors for the development of CRPC in patients (P<0.05). We plotted the receiver operating characteristic curves for predicting CRPC based on the indicators of patients. The area under the curve for Gleason score and the pre-treatment PSA level were 0.665 and 0.827, respectively, and 0.935 for the combination.
Conclusion: BSHXD combined with moxibustion had no effect on patients' progressive values of CRPC and did not enhance their outcomes. It was effective in improving their lower urinary symptoms, inflammation, and quality of life.
