World Health Organisation Classification of Tumors. Pathology and Genetics of Tumors of the Lung, Pleura, Thymus and Heart. 4th ed. WHO: Geneva, Switzerland; Pathology and Molecular Pathogenesis: Smoking Pathology and Molecular Pathogenesis: Bcl-2 and Hedgehog Signaling Small cell lung is the most closely linked with cigarette smoking. > 97% of patients have a history of cigarette smoking. Squamous cell carcinoma and large cell carcinoma have an intermediate association with smoking. Approximately 80% of patients have a history of cigarette smoking. Adenocarcinoma is the least closely linked to cigarette smoking. Approximately 70% of patients have a history of cigarette smoking. Bcl-2 is overexpressed in most small cell lung cancers. Oral Bcl-2 inhibitor, ABT-263 1, gossypol, and obatoclax (GX15-070) are in directed phase I and II trials for patients with SCLC. Hedgehog signaling presents in most small cell lung cancers. 3 Systemic hedgehog signaling antagonists (GDC-0449 and IPI-926) are being studied in small cell lung cancer in phase I trials as well Tse C, et al.

Nature. 2003;422(6929): Presentation Lung cancer typically presents in patients after the age of 50 and the percentage of women with SCLC has risen from 28% in the 1970s to 50% in The symptoms and signs of lung cancer are not specific and are commonly found in heavy cigarette smokers Govindan R, et al.

Limited Stage: Disease confined to one hemithorax with regional lymph nodes including either ipsilateral or bilateral hilar, mediastinal, and supraclavicular lymph node metastases and without ipsilateral pleural effusion that fit within a tolerable chest radiation field Extensive Stage: Disease beyond these boundaries

Systemic combination chemotherapy with etoposide and cisplatin is recommended. The recommendations for chest radiotherapy are: 1. No chest radiotherapy is needed. 2. Chest radiotherapy should start with the first or second cycle of chemotherapy. 3. Chest radiotherapy should start with the third or fourth cycle of chemotherapy. 4.

J Clin Oncol. 2002;20(24): Patients with limited stage SCLC should be treated with concurrent chest radiotherapy with etoposide plus cisplatin. These patients lived longer than patients treated with chemotherapy alone. The chest radiotherapy should start with Cycle 1 or 2. The chest radiotherapy should be given twice daily over three weeks. 29 Sundstrom S, et al. J Clin Oncol. 2002;20(24):

6 Surgery for Small Cell Lung Cancer Patients with a solitary pulmonary nodule and a diagnosis of small cell lung cancer should undergo evaluation for resection (2-3%). IASLC proposed TNM stage Patients should have mediastinoscopy because 20% will have positive lymph nodes. Patients should be treated with adjuvant chemotherapy following resection. Shepherd FA, et al. J Thoracic Oncol. 2007;2:1067 2: Strand TE, et al. Thorax. 2006;61(8): A patient presents with small cell lung cancer confined to the right upper lobe and mediastinum with adequate pulmonary reserve. Systemic combination chemotherapy with etoposide and cisplatin is recommended. The recommendations for chest radiotherapy are: 1. No chest radiotherapy is needed. 2. Chest radiotherapy should start with the first or second cycle of chemotherapy. 3. Chest radiotherapy should start with the third or fourth cycle of chemotherapy. 4. Chest radiotherapy should be given after the chemotherapy finishes Irinotecan for 2. 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. 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. 154 patients with extensive stage small cell lung cancer Randomized to 4 cycles of irinotecan 60 mg/m 2 IV on days 1, 8, and 15 plus cisplatin 60 mg/m 2 on day 1 on 28 day cycle vs etoposide 100 mg/m 2 on days 1, 2, and 3 plus cisplatin 80 mg/m 2 on day 1 every 3 weeks Followed for response rate, time to progression, and survival 35 Noda K, et al.

Etoposide and cisplatin remains the standard treatment. 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. 2.

8 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 Prophylactic Cranial Irradiation for Limited Stage Prophylactic Cranial Irradiation for Extensive Stage 45 Auperin, et al. N Engl J Med. 1999;341: Slotman B, et al. N Engl J Med. 2007;357(7): Prophylactic Cranial Irradiation Patients with SCLC have a 60-80% actuarial risk of developing brain metastases within 2 years after the start of treatment. PCI has been shown to prolong survival for patients with both limited and extensive SCLC who have a response to chemotherapy. PCI ( cgy) administered at the time of complete remission can reduce the chance of developing the brain metastases by 50-67%. 3.
