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.

Chemotherapy plus radiotherapy, followed by chemotherapy

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