Abstract

BACKGROUND AND OBJECTIVES:

To determine the prognostic factors for long-term survivors (LTS) with stage IV non-small cell lung cancer (NSCLC) who had undergone various treatments.

PATIENTS AND METHODS:

From 1990 to 1999, 222 NSCLC patients with stage IV disease, who had been treated in our department, were reviewed. As the initial treatment, 135 patients (48%) were treated with chemotherapy alone, 52 patients with a combination of chemotherapy and radiotherapy, 19 patients underwent an operation with or without any other therapeutic modalities and 16 were received radiotherapy alone.

RESULTS:

Seventeen (7.7%) patients survived for more than 2 years, and all but one had adenocarcinoma. Among these LTS, eight patients received surgery as the initial therapy, and 16 (94.1%) received some type of local-control therapy, including surgery or radiotherapy, during the course of their disease. Regarding the clinical characteristics between LTS and others (non-LTS), an early N status, a single metastatic site, a good performance status, and surgery for initial therapy were all found to be significantly important factors for LTS. A multivariate analysis using a logistic regression model also showed an early N status and surgical treatment to be significantly associated with LTS.

CONCLUSIONS:

Selected patients with an early N status may be appropriate candidates for aggressive multimodality treatment including surgery, in order to provide a long-term survival for stage IV NSCLC.
