Phase III study of the Eastern Cooperative Oncology Group (ECOG 2597): induction chemotherapy followed by either standard thoracic radiotherapy or hyperfractionated accelerated radiotherapy for patients with unresectable stage IIIA and B non-small-cell lung cancer.

PURPOSE: To compare once-daily radiation therapy (qdRT) with hyperfractionated accelerated radiation therapy (HART) after two cycles of induction chemotherapy. PATIENTS AND METHODS: Eligible patients were treatment naive, and had stage IIIA and B unresectable non-small-cell lung cancer, Eastern Cooperative Oncology Group performance status 0/1, and normal organ function. Induction chemotherapy consisted of two cycles of carboplatin area under time-concentration curve 6 mg/mL . min plus paclitaxel 225 mg/m2 on day 1. RT consisted of arm 1 (qdRT), 64 Gy (2 Gy/d), versus arm 2 (HART), 57.6 Gy (1.5 Gy tid for 2.5 weeks). A total of 388 patients were needed to detect a 50% increase in median survival from 14 months of qdRT to 21 months of HART; accrual was not achieved and the study closed prematurely. RESULTS: Of 141 patients enrolled, 83% were randomly assigned after chemotherapy to qdRT (n = 59) or HART (n = 60). Median survival was 20.3 and 14.9 months for HART and qdRT, respectively (P = .28). Overall response was 25% and 22% for HART and qdRT, respectively (P = .69). Two- and 3-year survival was 44% and 34% for HART, and 24% and 14% for qdRT, respectively. Grade > or = 3 toxicities included esophagitis in 14 v nine patients, and pneumonitis in 0 v 6 patients for HART and qdRT, respectively. Any subsequent trials of the HART regimen must address the issues that led to early closure, including slow accrual, logistics of HART, mucosal toxicity, and the fact that concurrent chemoradiotherapy now seems more effective than sequential treatment. CONCLUSION: After two cycles of induction chemotherapy with carboplatin-paclitaxel, HART is feasible with an acceptable toxicity profile. Although statistical significance was not achieved and the study closed early, there was a positive statistical trend suggesting a survival advantage with the HART regimen.     

Cisplatin plus etoposide chemotherapy followed by thoracic irradiation and paclitaxel plus cisplatin consolidation therapy for patients with limited stage small cell lung carcinoma

PURPOSE: To evaluate the efficacy and tolerance of a cisplatin plus etoposide regimen followed by thoracic radiotherapy (TRT) and paclitaxel plus cisplatin consolidation chemotherapy in patients with limited stage small cell lung cancer (SCLC). PATIENTS AND METHODS: Thirty-nine patients with limited SCLC were enrolled onto this study. Patients received three courses of cisplatin 75 mg/m2 i.v., day 1 and etoposide 100 mg/m2 i.v., days 1-3 (EP regimen), followed by TRT (45-56 Gy administered in 15 fractions), and three courses of paclitaxel 175 mg/m2 i.v., day 1 and cisplatin, as previously, on day 2 (PP regimen); cycles were repeated every 21 days. RESULTS: All patients were evaluable for toxicity and 34 for response. The overall response rate was 67% (CR: 26%; PR: 41%; intention-to-treat analysis) (95% CI: 53.0-84.2%). After a median follow-up period of 15 months, the median survival time was 15 months, the median time to tumor progression 8.3 months and the 1-year survival rate 53.8%. Grade 3/4 neutropenia occurred in 39% and 36% of patients receiving EP and PP regimens, respectively. The incidence of febrile neutropenia was 5% and 3% for EP and PP regimens, respectively. Other hematologic and non-hematologic toxicities were mild, with the exception of esophagitis occurring in 36% of patients during and/or immediately after radiotherapy. CONCLUSION: Consolidation therapy with PP after sequential EP and thoracic radiotherapy is feasible and well-tolerated; however, the efficacy results are comparable with those previously obtained in the same patients' population using a combination of EP and TRT.     

Topotecan and etoposide as first-line therapy for extensive disease small cell lung cancer: a phase II trial of a platinum-free regimen

In the treatment of extensive disease of small cell lung cancer (ED SCLC) there is an urgent need for more effective and better-tolerated drug regimens. We report on a prospective phase II trial performed to evaluate the efficacy and safety of a platinum-free regimen--containing topotecan and etoposide--in the first-line treatment of ED SCLC. Between December 1999 and July 2001, 28 chemotherapy-naive patients with ED SCLC were recruited; 9 patients had stage IIIB disease and 19 patients had stage IV disease. Based on phase I results, patients received treatment with intravenous topotecan 1 mg/m2 (days 1-5) followed by intravenous etoposide 75 mg/m2 (days 8-10). Treatment courses were repeated every 28 days for a maximum of 6 cycles. A confirmed response rate of 46.4% with 1 complete response (CR) and 12 partial responses (PR) (95% CI=27.5-66.1%) was observed. Stable disease (SD) was observed in 18% of patients. The median time to response was 7.9 weeks (range: 7.7-15.1 weeks) and median survival was 29.9 weeks (range from 3.3 to 91.4 weeks). Main toxicities encountered were haematological with Grade III/IV neutropenia in 2.6/1.5% of courses and Grade III/IV thrombocytopenia in 1.8%/0.7% of courses. These toxicities were manageable and were not associated with clinical sequels. Non-haematological toxicities were generally mild with no Grade III/IV toxicities reported apart from Grade III alopecia. The combination therapy of topotecan and etoposide is active in first-line chemotherapy for patients with ED SCLC. The regimen showed a tolerable safety profile. Since drug scheduling plays a critical role in the combination of topoisomerase I and II inhibitors, concurrent administration of topotecan and etoposide might increase the efficacy.     

Hyperfractionated radiotherapy with concurrent chemotherapy for advanced esophageal cancer

The clinical efficacy and safety of hyperfractionated radiotherapy with concurrent chemotherapy were studied retrospectively in patients with primary advanced esophageal cancer. The subjects were 31 patients who were treated with hyperfractionated radiotherapy and concurrent chemotherapy in our institution between 1990 and 2001. The chemoradiotherapy consisted of cisplatin 70-80 mg/m2 on day one, and continuous infusion of 5-fluorouracil 700-800 mg/m2/24 hours on days 1 to 3, with concurrent hyperfractionated radiotherapy (57.6-72 Gy). Complete remission (CR) was observed in 17 cases, and partial response in 13 cases (response rate: 96. 7%). Three-year survival rate and 5-year survival rate were 35.5% and 26.3%, respectively. Grade 3/4 hematological toxicities included leukocytes in 7 patients (22.6%), hemoglobin in 6 patients (19.4%), and platelets in 4 patients (12.9%). Grade 3 dysphagia-esophageal related to radiation was observed in 3 patients (9.7%). Late toxicities occurred with the following incidences: hypothyroidism in 2 patients, benign esophageal strictures in 2 patients, pericardial effusion in 8 patients, and pleural effusion in 8 patients. The results suggest that combined chemotherapy and hyperfractionated radiotherapy is an effective and well-tolerated regimen.     

Chemotherapy with concurrent brain and thoracic radiotherapy in brain-only metastases of treatment naive small-cell lung cancer: a phase II study

To study the treatment outcomes of brain-only metastases from small-cell lung cancer (SCLC) at initial diagnose treated by chemotherapy with concurrent brain and thoracic radiotherapy (RT). From Jan 2004 to Jan 2009, 36 treatment-na?ve SCLC patients with brain-only metastases in Sun yat-sen University were enrolled. Treatment contained initial EP chemotherapy with concurrent whole-brain radiotherapy (WBRT). EP regimen consisted of etoposide 100 mg/m(2) IV d1-3, cisplatin 80 mg/m(2) IV d1, repeated every 3 weeks. WBRT with total dose of 30 Gy in 10 fractions was started within 1 week from the beginning of chemotherapy followed by thoracic RT including 2 Gy once daily to a total dose of 60 Gy. Treatment responses were evaluated after 3 cycles of chemotherapy. EP regimen was given totally 6 cycles for no tumor progression. Thirty-four patients were evaluable. All of the 20 CNS symptomatic patients experienced symptoms relief. Objective responses in the brain and primary thoracic lesions were observed in 26 (76.5%, 16CR + 10PR) and 29 (85.3%, 23CR + 6PR) patients, respectively. The median survival time (MST) was 19.2 months, and the 1-and 2-year overall survival rates (OS) were 70.6 and 29.4%, respectively, in all patients. Patients with CR response had the longest MST of 21.9 months and 1-and 2-year OS of 93.8 and 43.8%, respectively. Treatment toxicity profiles were acceptable. The treatment strategy of concurrent chemotherapy with brain and thoracic RT might achieve promising survival outcomes comparable to limited-stage SCLC in initially diagnosed SCLC with brain-only metastases.

Phase I/II trial of hyperfractionated accelerated chemoradiotherapy for unresectable advanced pancreatic cancer

BACKGROUND: We conducted a Phase I/II study to evaluate the local efficacy and toxicity of hyperfractionated accelerated radiotherapy (HART) combined with 5-fluorouracil (5-FU) and cisplatin (CDDP) in patients with unresectable advanced pancreatic cancer. METHODS: Thirty-five patients (15 with Stage 4A and 20 with Stage 4B disease according to TNM classification) were enrolled between August 1997 and August 2001 into this Phase I/II trial. All patients received concurrent HART (1.5 Gy twice daily separated by 6 h for 5 days per week), 5-FU (375 mg/m(2) given as continuous intravenous infusion), and CDDP (2 mg/m(2) given as 30-min infusion just before each fraction of irradiation). In the Phase I trial, the total dose of radiation was escalated from 27 to 45 Gy. RESULTS: Twenty-one patients were enrolled in the Phase I study and six patients were given the final planned dose (45 Gy) which did not exceed the maximum tolerated dose. Eleven patients (52.4%) suffered from Grade 3 or worse neutropenia. Vomiting and mucositis were observed in 21 (100%) and 12 (57.1%) patients, respectively. An additional 14 patients were entered in the Phase II trial and received a total dose of 45 Gy, which is recommended in Phase I trial. Concerning the local tumor control of 20 patients with the recommended regimen, 7 patients (35%) achieved partial response, 10 (50%) remained stable and local progressive disease occurred in 3 (15%). The median survival time and the overall 1-year survival rate were 11.2 months and 40.0%, respectively, in 20 patients who received the recommended regimen. In Stage 4A patients, they were 13.0 months and 70.0%, respectively. The trend of toxicities in patients with the recommended regimen was almost the same as that observed in the Phase I study. CONCLUSION: The chosen combined modality treatment was well tolerated, and showed an expected local efficacy for the treatment of unresectable advanced pancreatic cancer.
