To measure symptom palliation in patients treated with radiation therapy for advanced nonsmall cell lung cancer (NSCLC).
Five hundred thirty patients with NSCLC were treated at the Medical College of Virginia between 1988 and 1993. Sixty-three patients with the least favorable prognostic features received palliative radiation to 30 Gy in 10 or 12 fractions for symptoms related to the presence of intrathoracic tumor. The observer portion of the Lung Cancer Symptom Scale (LCSS) was employed in a retrospective chart review, scoring measures of appetite, fatigue, cough, dyspnea, hemoptysis, and pain.
In 54 evaluable patients, median survival was 4 months and was independent of age, stage, performance status, or histology. Ninety-six percent of the patients had at least one LCSS symptom at presentation. Fatigue was unaffected by therapy. Improvements in appetite (p = 0.68) and pain (p = 0.61) were not statistically significant. There was, however, a statistically significant reduction in cough (p = 0.01), hemoptysis (p = 0.001), and dyspnea (p = 0.0003). Self-limiting acute side effects included transient esophagitis in 37% of patients, though no severe toxicities were noted.
These results suggest symptomatic benefit from radiotherapy even in those NSCLC patients with advanced disease and a limited life expectancy. Treatment should be given to patients whose symptoms are most amenable to palliation. A site-specific quality of life instrument such as the LCSS should be included within any future clinical trial of NSCLC management so that symptom control may be scored as a treatment outcome in addition to disease-free survival.
测量接受放射治疗的晚期非小细胞肺癌(NSCLC)患者的症状缓解情况。
1988年至1993年间,弗吉尼亚医学院对530例NSCLC患者进行了治疗。63例预后特征最差的患者因胸内肿瘤相关症状接受了姑息性放疗,剂量为30 Gy,分10或12次。在回顾性病历审查中采用了肺癌症状量表(LCSS)的观察部分,对食欲、疲劳、咳嗽、呼吸困难、咯血和疼痛进行评分测量。
在54例可评估患者中,中位生存期为4个月,与年龄、分期、体能状态或组织学无关。96%的患者在就诊时至少有一项LCSS症状。疲劳不受治疗影响。食欲(p = 0.68)和疼痛(p = 0.61)的改善无统计学意义。然而,咳嗽(p = 0.01)、咯血(p = 0.001)和呼吸困难(p = 0.0003)有统计学意义的减轻。自限性急性副作用包括37%的患者出现短暂性食管炎,但未观察到严重毒性反应。
这些结果表明,即使是那些患有晚期疾病且预期寿命有限的NSCLC患者,放疗也能带来症状改善。应给予症状最适合缓解的患者治疗。在未来任何NSCLC治疗的临床试验中,应纳入如LCSS这样的特定部位生活质量工具,以便除无病生存外,症状控制也可作为治疗结果进行评分。
