Abstract 2299
Background
The optimal chemotherapy regimen for concurrent chemoradiation in locally advanced non-small cell lung cancer (NSCLC) remains unclear. Cisplatin-etoposide regimen related toxicity is high, weekly regimens have been investigating. We aimed to compare the efficacy and safety of different concurrent chemotherapy regimens in the context.
Methods
A total of 225 patients with locally advanced, unresectable stage III NSCLC included. Patients who treated with weekly docetaxel-platin (DP), paclitaxel-platin (PP) and standard dose etoposide-platin (EP) chemotherapy regimens were selected and divided to groups for the comparison of toxicity, response rate, progression free survival (PFS) and overall survival (OS) rates.
Results
There was statistically significant difference between overall response rate of each treatment groups (DP: 96,1%, PP: 94% and EP:76.7%, p < 0.001). The median PFS rate of patients who treated with DP, PP and EP was 16, 15 and 13.3 months, respectively (p = 0.435). The median OS of patients treated with DP, PP and EP was 19.2, 29.7 and 28.3 months, respectively (p = 0.092). The rates of adverse events such as nausea, vomiting, neuropathy and anaphylaxis was similar. Grade 1-2 mucositis or esophagitis, anemia, pneumonitis were significantly higher in PP group than other groups. However, hematologic toxicities were higher in the EP group than other groups.Table:

Median age | 61 | 64 | 58 | 0.038 |

Stage IIIB-IIIC | 65(63.7) | 31(62) | 41(56.2) | 0.59 |
Conclusions
When the weekly chemotherapy regimens were compared with the standard dose, our study demonstrated similar survival rates but better treatment response rates. Adverse events and toxicity rates were different and depending on the type of chemotherapy regimen used.
