Small cell lung cancer (SCLC) is an aggressive malignancy but with a high response rate to chemotherapy. Eastern Cooperative Oncology Group performance status (ECOG PS) has been recognized as one of the main prognostic factors in SCLC. There are few data about risk-benefit ratio of chemotherapy over exclusive best supportive care in ECOG PS 3 and 4 patients. This study was performed to assess the outcome of poor ECOG PS SCLC patients that received chemotherapy in our institution.
A retrospective review of medical records from patients with ECOG PS 3-4 SCLC, who received systemic chemotherapy, was performed between January 2001 and December 2006 at the Instituto Nacional do Câncer, Rio de Janeiro, Brazil.
A total of 40 patients were included. Extensive disease was observed in 85% of patients and 25% had PS 4. The median overall survival was 53 days (64 days for ECOG PS 3 and 7 days for ECOG PS 4). There were 30% of early deaths. On univariate analysis, lactate dehydrogenase value, need for hospital admission, and exposure to radiotherapy had impact on survival. ECOG PS 3 patients had better survival than PS 4 patients, even when adjusted for stage. On multivariate analysis, ECOG PS, combined with stage, sustained a major influence on survival.
Median survival for ECOG PS 4 patients treated with chemotherapy in our series was extremely short with a high rate of early deaths. ECOG PS 3 patients also showed a poor survival. These data suggest that we need a more comprehensive approach and further studies, regarding the palliative care of this high-risk population.
小细胞肺癌(SCLC)是一种侵袭性恶性肿瘤,但对化疗有很高的反应率。东部合作肿瘤学组表现状态(ECOG PS)已被认为是 SCLC 的主要预后因素之一。关于 ECOG PS 3 和 4 患者中化疗相对于单纯最佳支持治疗的风险效益比的数据很少。本研究旨在评估我们机构中接受化疗的 ECOG PS 3 级和 4 级 SCLC 患者的预后。
对 2001 年 1 月至 2006 年 12 月期间在巴西里约热内卢国家癌症研究所接受全身化疗的 ECOG PS 3-4 SCLC 患者的病历进行了回顾性分析。
共纳入 40 例患者。85%的患者有广泛疾病,25%的患者 PS 4。总生存期中位数为 53 天(ECOG PS 3 为 64 天,ECOG PS 4 为 7 天)。有 30%的患者早期死亡。单因素分析显示,乳酸脱氢酶值、住院需求和放疗暴露对生存有影响。ECOG PS 3 患者的生存状况优于 PS 4 患者,即使在调整了分期后也是如此。多因素分析显示,ECOG PS 与分期相结合,对生存有重大影响。
在我们的系列研究中,接受化疗的 ECOG PS 4 患者的中位生存期极短,早期死亡率较高。ECOG PS 3 患者的生存状况也较差。这些数据表明,我们需要更全面的方法和进一步的研究,关注这一高危人群的姑息治疗。
