ABSTRACT The objective of this trial was to evaluate the activity and safety of one of the newer platinum-based doublets as a neoadjuvant regimen in patients with unresectable Stage IIIA-bulky N2 and Stage IIIB nonsmall cell lung carcinoma (NSCLC).
From June 1996 to April 2000, 129 consecutive patients with locally advanced NSCLC were treated with gemcitabine, 1000 mg/m(2) on Days 1 and 8 and cisplatin, 70 mg/m(2) on Day 2 (GC) of a 21-day treatment cycle, for 4 cycles, as part of a combined-modality approach.
After induction chemotherapy, 80 patients (62%; 95% confidence interval, 53.6-70.4%) achieved a partial response, 43 patients (33%) had stable disease, and 6 patients (5%) had disease progression during chemotherapy. Forty patients (31%), were considered resectable and underwent thoracotomy. Complete resectability was obtained in 38 patients (29%), with 2% of patients achieving a pathologic complete response. After surgery, 9 patients with Mountain Classification Stage IIIA NSCLC and 9 patients with Stage IIIB NSCLC received definitive adjuvant radiotherapy. Forty-six of 52 patients with Stage IIIB disease and 24 of 37 patients with Stage IIIA disease who were not considered suitable for surgery received definitive radiotherapy. The median time to disease progression was 11.4 months, the median survival was 19.4 months (range, 1.2-55.2 + months), and the 1-year survival rate was 74%. The lungs (33%) and the brain (21%) were the main sites of recurrence. Major toxicity was comprised of Grade 3-4 thrombocytopenia, which occurred in 34 patients (27%).
GC administered according to a 3-week schedule was a highly active and safe regimen in patients with primary, unresectable, locally advanced NSCLC.

    ABSTRACT: Prognosis of stage IIIA N2 non-small cell lung cancer (NSCLC) remains poor despite the changes in therapeutic strategies. To assess long term results of neo adjuvant therapy followed by surgery for patients with stage IIIA N2 NSCLC and to analyze factors influencing survival. The methods adopted include: Retrospective review of medical records of 91 patients with stage IIIA N2 NSCLC, who received neo adjuvant therapy followed by surgery; collection of information on demographic information, staging procedure, preoperative therapy, clinical response, type of resection, pathologic response of tumor, status of lymph nodes and adjuvant chemotherapy; survival analysis by Kaplan-Meier and calculation of prognostic factors using log-rank and Cox regression model. All patients received a platinum-based chemotherapy and 23 (29.1%) had an associated radiotherapy. Eighty four patients underwent thoracotomy. Median survival was 26 months (95%CI, 22.6-30.8 months) with three and five year survival rates of 31.6 and 20.9%, respectively. Prognostic factors for survival on univariate analysis was clinical response (P = 0.032), complete resection (P = 0.002), pathologic tumor response ( P < 0.001), and lymph nodal down staging (P = 0.001). Multivariate analyses identified complete resection, pathologic tumor response and lymph nodal down staging as independent prognostic factors. Survival of patients with stage IIIA N2 NSCLC who received neo adjuvant therapy is significantly influenced by clinical response, complete resection, pathologic tumor response, and lymph nodal down staging. These results can be helpful in guiding standard clinical practice and evaluating the outcome of neo adjuvant therapy followed by surgery in patients with stage IIIA N2 NSCLC.

    ABSTRACT: Our objective was to determine the activity in terms of response rate, surgical resectability, and the tolerability of the new three-drug combination gemcitabine-cisplatin-paclitaxel (GCP) in unresectable stage IIIA(N2) and IIIB non-small cell lung cancer (NSCLC). Forty-two chemo-naive patients with stage IIIA(N2)-IIIB NSCLC, median age of 59 years, Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, and the ability to tolerate pneumectomy, received gemcitabine (Gem) 1000 mg/m(2) IV days 1 and 8, cisplatin (CDDP) 50 mg/m(2) IV days 1 and 8, paclitaxel 125 mg/m(2) 1h infusion IV days 1 and 8, every 21 days for 3 cycles. After induction chemotherapy, patients were evaluated for surgery or definitive radiotherapy. Grade 3-4 neutropenia was the main hematologic toxicity, occurring in 28% of patients. Grade 3-4 thrombocytopenia was observed in only 11% of cases. No neutropenic fever or bleeding episodes were recorded. Severe non-hematologic toxicity was uncommon. Thirty (71%, 95% CI: 57.2-84.7%) of the 42 eligible patients had objective responses (1 complete and 29 partial responses). After induction chemotherapy, 21 patients (50%) went to surgery. Complete resection was obtained in 16 patients (38%). Viable tumor was present in 18 of 21 resection specimens. In three cases only necrotic tumor cells were identified, for a pathological complete response of 7%. With a median follow-up of 13.9 months, median time to progression was 17.4 months, median survival 21.7 months and estimated 1-year survival 92%. GCP combination is active and well tolerated in locally-advanced, non-resectable NSCLC. The activity profile, in terms of response and surgical resection rate, is comparable to that obtained with standard doublets.
