摘要
Objective： To analyze the correlations among comorbidity and overall survival （OS）, biochemical progression-free survival （b-PFS） and toxicity in elderly patients with localized prostate cancer treated with 125I brachytherapy. Methods： Elderly men, aged ≥65 years, with low-intermediate risk prostate cancer, were treated with permanent 125I brachytherapy as monotherapy. Comorbidity data were obtained from medical reports using age-adjusted Charlson comorbidity index （a-CCI）. The patients were categorized into two age groups （〈75 and 〉75 years old）, and two comorbidity score groups （a-CCI ≤3 and 〉3）. Toxicity was scored with Radiation Therapy Oncology Group （RTOG） scale. Results： From June 2003 to October 2009, a total of 92 elderly patients underwent prostate brachytherapy, including 57 men （62%） with low-risk prostate cancer, and 35 men （38%） with intermediate-risk prostate cancer. The median age of patients was 75 years （range, 65-87 years）. Forty-seven patients （51%） bad a-CCI _〈3 and 45 patients （49%） a-CCI 〉3. With a median follow-up period of 56 months （range, 24-103 months）, the 5-year actuarial OS and b-PFS were 91.3% and 92.4% respectively, without statistical significance between two Charlson score groups. Toxicity was mild. None of the patients experienced gastrointestinal （GI） toxicity, and only 4 patiens （4%） experienced late genitourinary （GU） grade-3 （G3） toxicity. No correlation between acute GU and GI toxicity and eomorbidity was showed （P=0.50 and P=0.70, respectively）. Conclusions： Our data suggest that elderly men with low-intermediate risk prostate cancer and comorbidity can be considered for a radical treatment as 12Sl low-dose rate brachytherapy.
