Chemotherapy followed by radiotherapy

The list bellow show the options for chemotherapy followed by radiation therapy based on the 2014 NCCN Non-Small Cell Lung Cancer guidelines.

• Cisplatin 100 mg/m² on days 1 and 29 + vinblastin 5 mg/m² per week on days 1, 8, 15, 22 and 29, then followed by radiation therapy.
• Paclitaxel 200 mg/m² administered for 3 hours in the first day + carboplatin AUC 6 administered in 1 hour and then every 21 days to a total of 2 cycles followed by thoracic radiation therapy.
