The use of regional anesthesia for cancer surgery has been associated with improved oncologic outcomes. One of the proposed mechanisms is a reduction in the use of systemic opioids that may cause immunosuppression. We used a retrospective matched cohort design to compare long-term oncologic outcomes after prostatectomy for cancer performed under general anesthesia with systemic opioids or with epidural anesthesia with epidural fentanyl analgesia. Since epidural fentanyl is quickly reabsorbed systemically, we hypothesized that there would be no difference in long-term oncological outcomes between the 2 groups.
There were 486 men who underwent prostatectomy performed under epidural anesthesia between January 1, 1991, and January 31, 1996. They were 1:1 matched based on age (±5 years), surgical year (±1 year), and baseline prostate cancer pathology to patients who had general anesthesia with systemic opioids. Long-term cancer outcomes and all-cause mortality were examined. Analyses were performed using stratified proportional hazards regression models, with hazard ratios >1 indicating worse outcome for general anesthesia only compared with epidural anesthesia and fentanyl analgesia.
After adjusting for positive surgical margins and adjuvant therapies, patients in the general anesthesia group were found not to be at increased risk of prostate cancer recurrence (hazard ratio [HR] = 0.79, 95% confidence interval [CI], 0.60-1.04], systemic tumor progression (HR = 0.92, 95% CI, 0.46-1.84), cancer-specific mortality (HR = 0.53, 95% CI, 0.18-1.58), or overall mortality (HR = 1.23, 95% CI 0.93-1.63) when compared with patients who received epidural anesthesia.
Compared with general anesthesia with systemic opioids, epidural anesthesia and analgesia with fentanyl were not associated with improvement in oncologic outcomes in patients undergoing radical prostatectomy for cancer.
区域麻醉用于癌症手术已被证明与改善肿瘤学预后相关。一种提出的机制是减少可能导致免疫抑制的全身性阿片类药物的使用。我们采用回顾性匹配队列设计,比较全身麻醉联合全身性阿片类药物与硬膜外麻醉联合硬膜外芬太尼镇痛下行前列腺癌根治术后的长期肿瘤学预后。由于硬膜外芬太尼可迅速被全身重吸收,我们推测两组的长期肿瘤学预后无差异。
1991年1月1日至1996年1月31日期间,有486名男性在硬膜外麻醉下行前列腺切除术。根据年龄(±5岁)、手术年份(±1年)和基线前列腺癌病理情况,将他们与接受全身麻醉联合全身性阿片类药物的患者进行1:1匹配。检查长期癌症预后和全因死亡率。使用分层比例风险回归模型进行分析,风险比>1表明仅全身麻醉与硬膜外麻醉和芬太尼镇痛相比预后更差。
在调整手术切缘阳性和辅助治疗后,发现全身麻醉组患者与接受硬膜外麻醉的患者相比,前列腺癌复发风险未增加(风险比[HR]=0.79,95%置信区间[CI],0.60 - 1.04),全身肿瘤进展风险(HR = 0.92,95% CI,0.46 - 1.84),癌症特异性死亡率(HR = 0.53,95% CI,0.18 - 1.58)或总死亡率(HR = 1.23,95% CI 0.93 - 1.63)。
与全身麻醉联合全身性阿片类药物相比,硬膜外麻醉联合芬太尼镇痛与接受前列腺癌根治术患者的肿瘤学预后改善无关。
