摘要

背景。体重指数(BMI)增加与死亡风险增加有关;然而,量化接受雄激素剥夺治疗(ADT)治疗前列腺癌(PC)的男性体重增加仍未研究。方法。1995年至2001年间,206名男性参加了一项随机试验,评估在放射治疗(RT)中增加6个月ADT的生存差异。研究队列中171名男性的BMI测量数据可用。主要终点是6个月随访时体重增加≥10磅。进行逻辑回归分析以评估基线BMI或接受的治疗是否与已知预后因素调整后的终点相关。结果。在6个月的随访中,12名男性体重增加≥10磅,其中10名(83%)接受了RT + ADT治疗,其中7名(70%)在随机分组时为肥胖。与RT + ADT相比,接受RT治疗的男性体重增加≥10磅的可能性较小(调整优势比(AOR): 0.18 [95% CI: 0.04-0.89];P = 0.04),而这种风险随着BMI的增加而增加(AOR: 1.15 [95% CI: 1.01-1.31];P = 0.04)。结论。对于患有低风险或中风险PC的肥胖男性,应考虑避免ADT,这些患者的癌症控制没有得到改善,但体重增加预计会缩短预期寿命。

Obesity and the Odds of Weight Gain following Androgen Deprivation Therapy for Prostate Cancer.

Background. Increasing body mass index (BMI) is associated with increased risk of mortality; however, quantifying weight gain in men undergoing androgen deprivation therapy (ADT) for prostate cancer (PC) remains unexplored. Methods. Between 1995 and 2001, 206 men were enrolled in a randomized trial evaluating the survival difference of adding 6 months of ADT to radiation therapy (RT). BMI measurements were available in 171 men comprising the study cohort. The primary endpoint was weight gain of ≥10 lbs by 6-month followup. Logistic regression analysis was performed to assess whether baseline BMI or treatment received was associated with this endpoint adjusting for known prognostic factors. Results. By the 6-month followup, 12 men gained ≥10 lbs, of which 10 (83%) received RT + ADT and, of these, 7 (70%) were obese at randomization. Men treated with RT as compared to RT + ADT were less likely to gain ≥10 lbs (adjusted odds ratio (AOR): 0.18 [95% CI: 0.04-0.89]; P = 0.04), whereas this risk increased with increasing BMI (AOR: 1.15 [95% CI: 1.01-1.31]; P = 0.04). Conclusions. Consideration should be given to avoid ADT in obese men with low- or favorable-intermediate risk PC where improved cancer control has not been observed, but shortened life expectancy from weight gain is expected.
