The aim of this study was to evaluate pain intensity and the application of the WHO guidelines for cancer pain treatment in patients with prostate cancer treated at Swiss cancer centers.
We analyzed a series of five multicenter phase II clinical trials which examined the palliative effect of different chemotherapies in patients with advanced hormone-refractory prostate carcinoma. Of 170 patients, 1,018 visits were evaluable for our purpose, including ratings of pain intensity by patients and prescribed analgesics.
No or mild pain was indicated by patients in 36 to 55% of the visits, more than mild pain in 30 to 46%. In 21% of the visits, the WHO pain treatment criteria (treatment according to one of the three steps; oral, rectal or transdermal application of the main dose; administration on a regular schedule) were fulfilled, and the Cleeland index was positive according to all recommendations. In 6% of the visits, neither the WHO criteria were fulfilled nor was the Cleeland index positive. This indicates insufficient pain treatment not following the WHO guidelines and that the prescribed analgesics were not sufficiently potent for the rated pain intensity.
In this selective Swiss sample, the standard of analgesic treatment is high. However, there is still scope for improvement. This cannot solely be solved by improving the knowledge of the physicians. Programs to change the patients' attitude towards cancer pain, training to improve the physicians' communication skills, and institutional changes may be promising strategies.
本研究旨在评估瑞士癌症中心接受治疗的前列腺癌患者的疼痛强度以及世界卫生组织癌症疼痛治疗指南的应用情况。
我们分析了一系列五项多中心II期临床试验,这些试验研究了不同化疗方案对晚期激素难治性前列腺癌患者的姑息治疗效果。在170名患者中,有1018次就诊可用于我们的研究目的,包括患者的疼痛强度评分和开具的镇痛药。
在36%至55%的就诊中,患者表示无疼痛或轻度疼痛,30%至46%的就诊中疼痛超过轻度。在21%的就诊中,符合世界卫生组织疼痛治疗标准(按照三个步骤之一进行治疗;口服、直肠或经皮应用主要剂量;定期给药),并且根据所有建议,克利兰德指数为阳性。在6%的就诊中,既未符合世界卫生组织标准,克利兰德指数也未呈阳性。这表明疼痛治疗未遵循世界卫生组织指南,且开具的镇痛药对所评定的疼痛强度效力不足。
在这个经过挑选的瑞士样本中,镇痛治疗标准较高。然而,仍有改进空间。这不能仅通过提高医生的知识水平来解决。改变患者对癌症疼痛态度的项目、提高医生沟通技巧的培训以及机构变革可能是有前景的策略。
