Although most treatment for non-small cell lung cancer is palliative, data on the adequacy of symptom control are scanty and there has been little discussion about the appropriate indices.
Two hundred and eighty nine unselected patients presenting sequentially to six specialists were studied; 242 cases were confirmed histologically and all were managed as non-small cell lung cancer. At presentation and two monthly for one year or until death each of 12 symptoms was graded by a physician at a clinic interview on a four point scale as absent, mild, moderate, or severe. For each symptom a palliative index (median duration of control/median duration of survival) was calculated, where control was defined as an improvement in symptoms of any severity by one grade or more.
Sixty four (22%) patients had surgery, 15 (5%) radical and 107 (37%) palliative radiotherapy, and 103 (36%) best supportive care. Analysis showed that most symptoms inexorably worsened with time. The palliation index for haemoptysis was 86%, chest pain 73%, cough 34%, and breathlessness 30%; for systemic symptoms it was 54% for anorexia and 47% for malaise. Palliation was poor in many patients after surgery. Breathlessness was a particular problem in the group having best supportive care.
The frequency of most symptoms in non-small cell lung cancer increases inexorably with time until malaise and anorexia are almost universal. Haemoptysis and chest pain are better palliated than cough and breathlessness. Present treatments fail to give adequate palliation for many patients, and the emphasis in future therapeutic studies should be on the relief of the more severe symptoms.
尽管大多数非小细胞肺癌的治疗是姑息性的,但关于症状控制充分性的数据却很少,而且对于合适的指标也鲜有讨论。
对依次就诊于六位专家的289例未经挑选的患者进行了研究;242例经组织学确诊,均被作为非小细胞肺癌进行治疗。在初诊时以及之后的一年中每两个月或直至死亡,由医生在门诊访谈中对12种症状中的每一种按照无、轻、中、重四级进行评分。对于每种症状,计算一个姑息指数(症状得到控制的中位持续时间/生存的中位持续时间),其中控制定义为任何严重程度的症状改善一个等级或更多。
64例(22%)患者接受了手术,15例(5%)接受了根治性手术,107例(37%)接受了姑息性放疗,103例(36%)接受了最佳支持治疗。分析表明,大多数症状随着时间的推移不可避免地恶化。咯血的姑息指数为86%,胸痛为73%,咳嗽为34%,气促为30%;全身症状中,厌食的姑息指数为54%,不适为47%。许多患者术后姑息效果不佳。在接受最佳支持治疗的患者组中,气促是一个特别突出的问题。
非小细胞肺癌中大多数症状的发生频率随着时间的推移不可避免地增加,直至不适和厌食几乎普遍存在。咯血和胸痛的姑息效果优于咳嗽和气促。目前的治疗方法未能为许多患者提供充分的姑息治疗,未来治疗研究应重点关注缓解更严重的症状。
