PURPOSE This study aimed to analyze the efficacy and toxicity of gemcitabine plus platinum chemotherapy for patients aged 70 years or older with advanced non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS We reviewed the records of stage IIIB, IV NSCLC patients or surgically inoperable stage II, IIIA NSCLC patients who were aged 70 years or older when treated with gemcitabine (1,250 mg/m2) plus cisplatin (75 mg/m2) or carboplatin (AUC5) chemotherapy from 2001 to 2010 at Seoul St. Mary's Hospital, Uijeongbu St. Mary's Hospital and St. Vincent's Hospital. Gemcitabine was administered on days 1 and 8, and cisplatin or carboplatin was administered on day 1. Treatments were repeated every 3 weeks for a maximum of 4 cycles. RESULTS The median age of the 62 patients was 73.5 years (range, 70 to 84 years). Forty-one (66%) patients exhibited comorbidity. The mean number of treatment cycles was 3.9.
The compared average relative dose intensity of gemcitabine plus platinum chemotherapy was 84.8%. The median progression-free survival and overall survival (OS) were 5.0 months and 9.4 months, respectively. Reduced Eastern Cooperative Oncology Group (ECOG) performance status (none vs. > or =1) and weight loss (<5% vs. > or =5%) after treatment were found to have a significant effect on OS (p=0.01). CONCLUSION Gemcitabine plus platinum chemotherapy is an effective treatment option with an acceptable level of toxicity in patients aged 70 years or older with good performance status in advanced NSCLC.

PURPOSE To evaluate treatment outcomes and prognostic factors in non-small cell lung cancer (NSCLC) patients treated with concurrent chemoradiation. MATERIALS AND METHODS From January 2005 to June 2009, 51 patients were treated with concurrent chemoradiation for 3 different aims: locally advanced stage III, locally recurrent disease, and postoperative gross residual NSCLC.
Median age was 63 years. Distribution of stages by the 6th edition of American Joint Committee on Cancer (AJCC) was as follows: IIIA (37.3%), IIIB (56.9%). Chemotherapy was administered every week concurrently with radiation using one of the following regimens: paclitaxel (60 mg/m2), docetaxel+cisplatin (20 mg/m2+20 mg/m2), cisplatin (30 mg/m2). Total radiation dose was 16-66.4 Gy (median, 59.4 Gy). RESULTS Median follow-up duration was 40.8 months. The overall response rate was 84.3% with 23 complete responses.
The median survival duration for the overall patient group was 17.6 months. The 3-year survival rate was 17.8%. A total of 21 patients had recurrent disease at the following sites: loco-regional sites (23.6%), distant organs (27.5%). In the multivariate analysis of the overall patient group, a clinical tumor response (p=0.002) was the only significant prognostic factor for overall survival (OS). In the multivariate analysis of the definitive chemoradiation arm, the use of consolidation chemotherapy (p=0.022), biologically equivalent dose (BED)10 (p=0.007), and a clinical tumor response (p=0.030) were the significant prognostic factors for OS.The median survival duration of the locally recurrent group and the postoperative gross residual group were 26.4 and 23.9 months, respectively. CONCLUSION Our study demonstrated that clinical tumor response was significantly associated with OS in the overall patient group. Further investigations regarding the optimal radiation dose in the definitive chemoradiation and the optimal treatment scheme in locally recurrent NSCLC would be required.
