Chemotherapy is recommended 1. Irinotecan plus cisplatin is more effective for patients with extensive stage small cell lung cancer than etoposide plus cisplatin. 2. Etoposide cisplatin is as effective as other chemotherapy regimens that have been tested thus far. 3. Giving high doses of chemotherapy with autologous bone marrow transplantation will prolong their survival. 4. Adding the antiangiogenic agent, Thalidomide, to combination chemotherapy prolongs survival. Noda K, et al. N Engl J Med. 2002;346(2):85-91. Humblet Y, et al.

Patients with Small Cell Lung Cancer Treated with Intensive Chemotherapy (Adding Paclitaxel or Autologous Transplant Doses) Do Not Live Longer Than Patients Treated with Standard Doses. A patient presents with small cell lung cancer with involvement of the left upper lobe, mediastinum, and thoracic spine. Chemotherapy is recommended. 1. Irinotecan plus cisplatin is more effective for patients with extensive stage small cell lung cancer than etoposide plus cisplatin. 2. Etoposide cisplatin is as effective as other chemotherapy regimens that have been tested thus far. 3.

A patient with limited stage small cell lung cancer undergoes chemotherapy and chest radiotherapy. The radiographic imaging after the completion of treatment shows a complete response. The considerations about using prophylactic cranial irradiation for patients with small cell lung cancer and a response to treatment include: 1. Prophylactic cranial irradiation is recommended for only patients with limited stage small cell lung cancer with a response to treatment 2. Prophylactic cranial irradiation is recommended for patients with both limited and extensive stage small cell lung cancer after completion of their treatment 3. Prophylactic cranial irradiation has no impact on survival but reduces the chance of getting brain metastases 4. Prophylactic cranial irradiation can reduce the risk of brain metastases and prolong survival 7
