Randomized comparison of early versus late hyperfractionated thoracic irradiation concurrently with chemotherapy in limited disease small-cell lung cancer: a randomized phase II study of the Hellenic Cooperative Oncology Group (HeCOG).

Background: Concurrent platinum etoposide chemotherapy given in combination with hyperfractionated thoracic radiation therapy (HTRT) in limited disease (LD) small cell lung cancer (SCLC) is associated with a high response rate and significant prolongation of survival. Given these results, the Hellenic Cooperative Oncology Group (HeCOG) performed a multicenter randomized phase II study in patients with LD SCLC to evaluate the timing of HTRT (early vs. late) when given concurrently with chemotherapy.

Weekly alternating non-cross-resistant chemotherapy for small cell lung cancer with a good prognosis: a study of the Hellenic Cooperative Oncology Group.

This trial was conducted by the Hellenic Cooperative Oncology Group to improve the responses and survival in small cell lung cancer with a good prognosis, using a weekly intensive chemotherapy with alternated non-cross-resistant myelosuppressive agents. Patients were classified into two groups; group A consisted of those who received the initial designed regimen (29 patients), and group B consisted of those who received the more intensified regimen that increased by 25% the doses of carboplatin, epirubicin, and ifosfamide, and by 33% the doses of etoposide given on days 1, 2, and 3 with prophylactic granulocyte colony-stimulating factor support. Chemotherapy in group A consisted of carboplatin 150 mg/m2 in 250 ml of 5% dextrose in water as an 1-hour infusion on day 1, etoposide 75 mg/m2 in 250 ml normal saline as an 1-hour infusion on days 1 and 2 alternating with epirubicin 30 mg/m2 intravenous push on day 8, and ifosfamide 2 g/m2 in 500 ml 5% dextrose in water as a 2-hour infusion with mesna protection on day 8.
