Paclitaxel, cisplatin, and vinorelbine combination chemotherapy in metastatic non-small-cell lung cancer

Vinorelbine-cisplatin combination chemotherapy is a standard approach for the treatment of advanced non-small-cell lung cancer (NSCLC). The addition of paclitaxel as a third therapeutic agent seems promising. The aim of the present study was to evaluate the activity and toxicity of this new regimen. Forty-six nonselected and chemotherapy-naive patients with stage IV NSCLC and an Eastern Cooperative Oncology Group performance status of 0 to 2 were treated every 4 weeks with paclitaxel (135 mg/m2 given iv in 3 hours) and cisplatin (120 mg/m2 given iv in 6 hours) on day 1 and vinorelbine (30 mg/m2 given iv in 30 minutes) on days 1 and 15. All patients were evaluated for toxicity and response according to the intent-to-treat principle. An objective response was observed in 39% of the patients (95% CI: 25% to 55%). World Health Organization grade III to IV neutropenia, thrombocytopenia, and anemia occurred in 43%, 2%, and 17%, respectively. There was one treatment-related death. Nonhematologic toxicities were mild, mainly grade III nausea and vomiting in 20% of the patients. After a median follow-up period of 54 months, the median progression-free survival was 14.3 weeks and the median overall survival was 31.3 weeks. This three-drug chemotherapy combination is feasible, well tolerated, and shows activity in metastatic NSCLC.     

Induction chemotherapy followed by concurrent chemoradiation for patients with non-operable stage III non-small-cell lung cancer

Combined modality treatment with chemotherapy (CT) and radiotherapy (RT) in stage III non-small-cell lung cancer is considered as standard therapy. As concomitant CT appears to be beneficial, the choice of anticancer agents and the role of induction chemotherapy is still unresolved. We present our experience based on an induction CT scheme with carboplatin plus paclitaxel followed by RT and concomitant CT. 31 patients with non-operable stage IIIA or IIIB NSCLC without pleural effusion were included in this study: 30 males, 1 female; median age 66 years (range: 50-81); 32% with non-operable stage IIIA and 68% with stage IIIB without pleural effusion; 61% squamous cell carcinoma, 32% adenocarcinoma and 7% other histologies. Regarding performance status (PS), 9.7% PS 0 and 90% PS 1 were included. Patients received 3 courses of induction CT with carboplatin AUC=6 and paclitaxel 175 mg/m(2), administrated i.v. on day 1 of each 21-day cycle, followed by thoracic irradiation (total dose 60-65 Gy, daily fractions 1.8-2 Gy) with two concurrent courses of carboplatin/paclitaxel. 16.2% of the patients achieved complete response, 48.4% partial response, 25.8% stable disease and 9.6% progression of disease. Median progression-free and overall survival was 12 and 18 months, respectively. The most frequent haematological toxicities were grade (G) 3 anaemia in 19.3%, G3 neutropenia in 9.6% and G4 neutropenia in 12.9%. Esophageal G2 toxicity (RTOG) was observed in 28.1% of cases. The induction CT followed by concomitant chemoradiation used in this study appears feasible, safe and effective when administered to an unselected inoperable NSCLC stage III patient cohort in the everyday routine clinical practice. Further, our results are comparable to previously published phase III studies.

Effect of vinorelbine, ifosfamide, and cisplatin combination chemotherapy in advanced non-small-cell lung cancer

Cisplatin-based chemotherapy is being tried in the treatment of nonoperable cases of non-small-cell lung cancer (NSCLC). However, the prognosis is unfavorable and to improve survival, clinical studies using various combinations of a variety of drugs as well as experimental material are in progress. We compared the efficacy and toxicities of combination chemotherapy using different doses of vinorelbine and ifosfamide with a constant dose of cisplatin in this study. Patients diagnosed with inoperable stage III or IV NSCLC between June 1997 and December 1998 were included. Cisplatin was administered at a constant dose of 80 mg/m2 on day 5, whereas vinorelbine on days 1 and 5 and ifosfamide on day 5 were administered in one of two different doses. In arm A, vinorelbine 25 mg/m2 and ifosfamide 3.0 g/m2 were administered. In arm B, vinorelbine 20 mg/m2 and ifosfamide 2.5 g/m2 were administered. Also, we reviewed for phase II and III studies that test 1) cisplatin, 2) vinorelbine monotherapy, and 3) vinorelbine/cisplatin/ifosfamide combination chemotherapy for stage IIIb-IV non-SCLC. Summation dose intensity (SDI) was calculated in each published and current study. Twenty patients in arm A and 35 patients in arm B were available for evaluation. There was no difference in patient activity, pathologic diagnosis, and differentiation or stage between the two arms. The median number of cycles was four in both arms. The response rate was 50% in arm A and 30% in arm B. The median survival times for arm A and B were 40 and 42 weeks, respectively, whereas the SDI was 1.94 and 1.7, respectively. More than grade III leukopenia was observed in 28.9% in arm A, which is more frequent than the 17.2% in arm B. There was a significant correlation between the SDIs and response rates and median survival (r2 = 0.629, p = 0.001; r2 = 0.453, p = 0.001, respectively). Although the follow-up period is relatively short, the survival time was similar in both arms. Because a high response rate may not be followed by a high survival time in combination chemotherapy of NSCLC, further studies on the appropriate dose of individual agents with regard to the relationship between response rate, severity, and incidence of toxicities and survival rate should be carried out.     

Induction chemotherapy with carboplatin-paclitaxel followed by standard radiotherapy with concurrent daily low-dose cisplatin plus weekly paclitaxel for inoperable non-small-cell lung cancer

Both induction chemotherapy and concurrent platinating agents have been shown to improve results of thoracic irradiation in the treatment of locally advanced non-small-cell lung cancer (NSCLC). This phase II study investigated activity and feasibility of a novel chemoradiation regimen, including platinum and paclitaxel, both as induction chemotherapy and concurrently with thoracic radiotherapy. Previously untreated patients with histologically/cytologically proven unresectable stage I-III NSCLC were eligible. Induction chemotherapy consisted of 2 courses of 200 mg/m2 paclitaxel and carboplatin at AUC of 6 mg/mL/min every 3 weeks. From day 43, continuous thoracic irradiation (60 Gy in 30 fractions radiotherapy for 6 weeks) was given concurrently with daily cisplatin at a dose of 5 mg/m2 intravenously and weekly paclitaxel at a dose of 45 mg/m2 for 6 weeks. Fifteen patients were accrued in the first stage of the trial. According to the previous statistical considerations, accrual at the second stage of the study was halted as a result of the achievement an insufficient number of successes. Major toxicity of combined chemoradiation was grade III-IV esophagitis requiring hospitalization for artificial nutrition, which occurred in 58% of patients. Other toxicities included grade II-IV fatigue in 75% of patients and grade I-IV neuromuscular toxicity in 67%. Only 7 patients completed the treatment program as scheduled. Eight patients (53.3%; 95% confidence interval, 26.5-78.7%) had a major response (5 partial response, 3 complete response), 2 patients had disease progression, and 1 was stable at the end of treatment. Four patients died early. With a median follow up of 38 months, the median survival was 12 months. A combined chemoradiation program, including platinum and paclitaxel, appears difficult to deliver at full dose as a result of toxicity, mainly esophagitis. More active and less toxic combined modality treatments need to be developed for inoperable NSCLC.     

Induction chemotherapy followed by concurrent standard radiotherapy and daily low-dose cisplatin in locally advanced non-small-cell lung cancer.

Both induction chemotherapy and concurrent low-dose cisplatin have been shown to improve results of thoracic irradiation in the treatment of locally advanced non-small-cell lung cancer (NSCLC). This phase II study was designed to investigate activity and feasibility of a novel chemoradiation regimen consisting of induction chemotherapy followed by standard radiotherapy and concurrent daily low-dose cisplatin. Previously untreated patients with histologically/cytologically proven unresectable stage IIIA/B NSCLC were eligible. Induction chemotherapy consisted of vinblastine 5 mg m(-2) intravenously (i.v.) on days 1, 8, 15, 22 and 29, and cisplatin 100 mg m(-2) i.v. on days 1 and 22 followed by continuous radiotherapy (60 Gy in 30 fractions) given concurrently with daily cisplatin at a dose of 5 mg m(-2) i.v. Thirty-two patients were enrolled. Major toxicity during induction chemotherapy was haematological: grade III-IV leukopenia was observed in 31% and grade II anaemia in 16% of the patients. The most common severe toxicity during concurrent chemoradiation consisted of grade III leukopenia (21% of the patients); grade III oesophagitis occurred in only two patients and pulmonary toxicity in one patient who died of this complication. Eighteen of 32 patients (56%, 95% CI 38-73%) had a major response (11 partial response, seven complete response). With a median follow-up of 38.4 months, the median survival was 12.5 months and the actuarial survival rates at 1, 2 and 3 years were 52%, 26% and 19% respectively. The median event-free survival was 8.3 months with a probability of 40%, 23% and 20% at 1, 2 and 3 years respectively. Induction chemotherapy followed by concurrent daily low-dose cisplatin and thoracic irradiation, in patients with locally advanced NSCLC, is active and feasible with minimal non-haematological toxicity. Long-term survival results are promising and appear to be similar to those of more toxic chemoradiation regimens, warranting further testing of this novel chemoradiation strategy.

Induction chemotherapy or chemoradiotherapy before surgery for non-small-cell lung cancer

Two controversies regarding the role of induction therapy before surgery in non-small-cell lung cancer are considered through a review of the literature and ongoing trials worldwide. The first debate asks whether surgery is indicated after induction chemotherapy or chemoradiotherapy for patients with advanced stage III disease. The second debate addresses disease presentations with early stage disease or radiographically negative but microscopically positive N2 involvement. The question raised for this group of patients is whether induction chemotherapy with or without radiotherapy should be routinely prescribed before the standard therapy of definitive surgery. For both controversies, data are provocative and in some subsets argue in favor of the more aggressive approach. However, changes in standardof-care recommendations are premature. Thus, ongoing worldwide trials maintain control arms of chemoradiotherapy alone and of surgery alone in the advanced and early disease subsets, respectively.     

Phase II study of induction chemotherapy with gemcitabine and vinorelbine followed by concurrent chemoradiotherapy with oral etoposide and cisplatin in patients with inoperable stage III non-small-cell lung cancer

PURPOSE: For locoregionally advanced inoperable non-small-cell lung cancer (NSCLC), concurrent chemoradiotherapy has become a standard therapy. We conducted a Phase II trial to examine the efficacy and toxicity of adding gemcitabine and vinorelbine induction chemotherapy to concurrent chemoradiotherapy with oral etoposide and cisplatin. METHODS AND MATERIALS: Eligibility included inoperable clinical Stage III NSCLC without pleural effusion, ECOG performance status 0-1, and weight loss < or =5%. Induction chemotherapy consisted of three cycles of gemcitabine 1,000 mg/m2 and vinorelbine 30 mg/m2, each given i.v. on Days 1 and 8, every 3 weeks. During once-daily thoracic radiotherapy (1.8 Gy/day, total 63 Gy), two cycles of oral etoposide (100 mg on Days 1-5 and 8-12) plus cisplatin (50 mg/m2 on Days 1 and 8) were given concurrently 4 weeks apart. RESULTS: Between April 2002 and November 2003, 42 patients were enrolled and 40 were included in response and toxicity evaluation. The median age was 59 years and 13 patients had IIIA and 27 had IIIB; 24 had squamous ca, 12 had adenocarcinoma, and 4 had others. Objective tumor responses were obtained in 29 patients (72.5%), including 18 (45.0%) after induction chemotherapy. After a median follow-up of 23.8 months, the median survival time and progression-free survival was 23.2 months and 10.9 months, respectively, with 2-year survival rate of 43.9%. For the patients with supraclavicular nodal involvement, the median survival time was 11.8 months with 2-year survival rate of 16.7%, whereas the corresponding figures were 27.8 months and 52.0%, respectively, for those without supraclavicular nodal involvement. Toxicity of induction chemotherapy was mild and well tolerated. However, concurrent chemoradiotherapy was associated with G3/4 hematologic toxicity in 75.7%, G3 esophagitis in 24.2%, and two treatment-related deaths. There were nonlife-threatening late toxicities in additional 6 patients. CONCLUSIONS: Induction chemotherapy with gemcitabine and vinorelbine followed by concurrent chemoradiotherapy with etoposide and cisplatin showed very promising survival in patients with Stage III NSCLC, especially in those without supraclavicular nodal involvement, which warrants further evaluation.     

Induction chemotherapy with triweekly docetaxel and cisplatin followed by concomitant chemoradiotherapy with or without surgery in stage III non-small-cell lung cancer: a phase II study

Background

The main goal of this study was to evaluate the feasibility and effectivity of triweekly docetaxel/cisplatin followed by weekly docetaxel/cisplatin concomitantly with radiotherapy with or without surgery in locally advanced non–small-cell lung cancer (NSCLC) patients.

Materials and Methods

Thirty five patients with locally advanced NSCLC were enrolled. Combination chemotherapy with triweekly docetaxel/cisplatin (75 mg/m²) was administered as induction regimen. After induction chemotherapy, patients were evaluated for surgery if their disease subsequently downstaged. Six cycles of weekly docetaxel/cisplatin (20 mg/m²) concurrently with radiotherapy up to a 60 Gy were administered after induction chemotherapy with or without surgery. Response, toxicity, time-to-progression and overall survival were evaluated.

Results

Twelve patients with stage IIIA-N2 and 23 patients with stage IIIB-T4N0-2 were evaluated (median age, 54 years). After 94 cycles of induction chemotherapy, partial response was achieved in 20 patients, 9 patients had stable disease and six had progressive disease. After overall treatment, 6 patients achieved complete response, 19 patients had partial response, 8 patients had progressive disease, and 2 patients had stable disease. Two patients experienced grade 3-4 pulmonary toxicity and 1 patient experienced grade 3 esophageal toxicity. Six patients underwent surgery. Median overall survival for all patients was 15 months and time-to-progression was 13 months with a median follow-up of 22 months.

Conclusion

Triweekly docetaxel plus cisplatin followed by weekly docetaxel plus cisplatin concomitantly with radiotherapy is effective and feasible and seems to be an alternative option for patients who have locally advanced NSCLC. Surgery may provide additional benefit for patients whose disease adequately downstaged after induction chemotherapy.     

Gemcitabine,cisplatin and vinorelbine as induction chemotherapy followed by radical therapy in stage III non-small-cell lung cancer: a multicentre study of galician-lung-cancer-group

PURPOSE: To determine the effectiveness of a gemcitabine-cisplatin-vinorelbine combination in patients with stage III non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Patients (n=46) with stage III NSCLC and naive of therapy were recruited into the trial to receive gemcitabine (G, 1000 mg/m(2)) on days 1 and 8, cisplatin (C, 100 mg/m(2)) on day 1 and vinorelbine (V, 25 mg/m(2)) on days 1 and 8 every 21 days for three cycles. RESULTS: Two patients achieved complete response (CR) and 23 partial response (PR), overall response 52%. Subsequent radical surgery included nine patients of whom four were non-resectable and five were resected and with 1 CR. Radiotherapy was administered to 31 patients, and two achieved CR. The median time to progression and overall survival were 37 and 50 weeks, respectively. Grade 3-4 neutropenia and thrombocytopenia occurred in 35% of cycles, with two toxic deaths. Severe non-haematological toxicity was uncommon. CONCLUSIONS: This GCV combination is effective in patients with stage III NSCLC, and with an acceptable toxicity.     

Biweekly regimen of cisplatin, gemcitabine and vinorelbine for advanced non-small-cell lung cancer

Purpose: Improving chemotherapeutic efficacy in non-small cell lung cancer (NSCLC) will require the development of new strategies to better use currently available agents. To assess the efficacy and safety of a biweekly regimen of cisplatin, gemcitabine and vinorelbine for advanced non-small-cell lung cancer. Methods: Patients with selected stage IIIb (pleural effusion)/stage IV NSCLC, performance status of 0–2 and normal organ function were eligible. Treatment consisted of cisplatin 100 mg/m² on day 1 plus gemcitabine, 1,000 mg/m² and vinorelbine 25 mg/m² on days 1 and 15 every 28 days. Results: Of the 40 patients enrolled and assessable for response, there were five (12.5%) with confirmed complete response and 14 (35%) with a confirmed partial response for an overall response rate of 47.5%. Nine patients had stable disease while 12 (30%) progressed. Median progression-free survival and overall survival for all patients were 6.3 and 11.1 months, respectively. Toxicity was principally hematologic, with grade 3–4 neutropenia in 30%, and grade 3–4 nausea/vomiting in 22.5%. There were no treatment-related deaths. Conclusions: The biweekly regimen of cisplatin, gemcitabine and vinorelbine is associated with a high rate of response, lesser toxicity than other three-drug regimens and no benefit of survival. Therefore, the regimen under study may be an appealing alternative when considering other treatment modalities for advanced lung cancer, such as neoadjuvant therapy.     

Induction chemotherapy for resectable non-small-cell lung cancer

Lung cancer remains the leading cause of cancer death in American men and women. Non-small-cell lung cancer (NSCLC) accounts for 85% of these cases. Although surgery is the best curative approach for resectable NSCLC, long-term survival for patients with operable disease remains poor. More than half of patients who initially present with stage I to IIIA disease experience relapse of metastatic disease. Postoperative adjuvant therapy has been evaluated in several randomized trials, and provides a survival benefit. It appears reasonable to look to induction chemotherapy, or preoperative chemotherapy, to provide a similar improvement in survival with early treatment of micrometastatic disease. Multiple trials of induction therapy have been carried out with encouraging results. The use of various induction regimens with chemotherapy alone or chemotherapy combined with radiotherapy for stage IIIA NSCLC is under investigation. Randomized trials are under way to better define the role of induction therapy in the multimodality treatment of NSCLC.     

Sequential chemotherapy of cisplatin and vinorelbine followed by paclitaxel and gemcitabine in advanced non-small-cell lung cancer. A single institution phase II study

BACKGROUND: To determine the activity and safety of a sequential regimen of cisplatin and vinorelbine followed by paclitaxel and gemcitabine in patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Treatment was two cycles of cisplatin 80 mg/m(2) on day 1 and vinorelbine 30 mg/m(2) on days 1 and 8 every 3 weeks followed by two cycles of paclitaxel 175 mg/m(2) on day 1 and gemcitabine 1250 mg/m(2) on days 1 and 8 every 3 weeks. RESULTS: Fifty-five patients with inoperable NSCLC, performance status 2 or less were enrolled, including 19 patients with brain lesions. There were 23 partial responses (42%; 95% confidence interval 29-55). The median time to progression and overall survival were 5.8 and 10.3 months, respectively (6.5 and 12.8 in the patient subset without brain metastases). One-year survival rate was 47.5%. Grade III/IV neutropenia was the major side effect; it occurred in 56% of patients and was mainly limited to the first two chemotherapy cycles with cisplatin and vinorelbine. CONCLUSIONS: Sequential combination of cisplatin and vinorelbine followed by paclitaxel and gemcitabine is a manageable and active regimen for patients with NSCLC. It deserves to be tested against a standard two-drug scheme in a phase III trial.     

Gemcitabine and vinorelbine followed by weekly docetaxel in patients with advanced non-small-cell lung cancer: a phase II trial of sequential chemotherapy

Objective We conducted this phase II trial to evaluate the efficacy and toxicity of the sequential nonplatinum combination chemotherapy consisting of gemcitabine (GEM) and vinorelbine (VNR) followed by weekly docetaxel (DOC) in patients with advanced non-small-cell lung cancer (NSCLC). Patients and methods Eligibility criteria: stage IV NSCLC, Performance status ≤2, adequate renal, hepatic and bone marrow function. Treatment consisted on: VNR 25 mg/m² plus gemcitabine 1000 mg/m², on days 1 and 8 of each 21-day cycle, followed by docetaxel 36 mg/m² weekly until progression or unacceptable toxicity. Results 21 stage IV patients were enrolled. All patients are evaluable for treatment response and toxicity profile. The mean age of the patients was 63 years (range: 51 to 72) with 18 (86%) males and 3 (14%) females. Histology types were: adenocarcinoma in 8 patients (38%), large cell carcinoma in 1 patients (5%) and squamous cell carcinoma in 12 patients (57%). The majority of the patients had and ECOG PS of 1. Eight patients (38%) did not complete six cycles of gemcitabine-navelbine. The median number of cycles of gemcitabine-navelbine was 4 (range 2–6). Of the 13 patients (61%) who completed six cycles of gemcitabine-navelbine, all of them went on to receive weekly docetaxel and received at least 3 cycles, with a median number of 8 cycles (range 3–16). The overall response rate was 33%. Respect survival, the minimum follow-up was 6 months (range, 6–25 months). The median survival time (MST) was 7.9 months, and the 1-year survival was 30%, and the median progression-free survival was 4.7 months. Toxicity was mild, well tolerated and mostly hematologic. In the GEM/VNR cycle, grade 3/4 neutropenia occurred in 14%, two patients with febrile neutropenia. Grade 3 anaemia in 1 patients (5%) and grade 3 thrombocytopenia in 1 patient (5%). Nonhematologic toxicity was also mild: 1 patient with Grade 3 skin toxicity with docetaxel, 1 patient with grade 3 infection, 2 patients with grade 3 astenia and 1 patient with a mild allergic reaction postchemotherapy treatment with docetaxel. Conclusion The sequential triplet nonplatinum chemotherapy consisted of GEM/VNR followed by weekly DOC is active and can be administered safely in advanced NSCLC. Our results are similar with other sequential regimens and did not represent a significant improvement in the treatment of this disease.     

Postoperative radiotherapy increases locoregional control of patients with stage IIIA non-small-cell lung cancer treated with induction chemotherapy followed by surgery

PURPOSE: To determine the effectiveness of postoperative radiotherapy (RT) in patients with Stage IIB and Stage IIIA non-small-cell lung cancer (NSCLC) treated with induction chemotherapy followed by surgery. METHODS AND MATERIALS: We retrospectively reviewed the treatment records of 98 patients (58 men and 40 women; median age 61 years, range 31-91) with Stage IIB and Stage IIIA NSCLC who were treated with induction chemotherapy followed by surgery at our institution between January 1990 and December 2000. Patients were grouped by treatment (chemotherapy/surgery alone vs. chemotherapy/surgery/RT), by disease stage and nodal classification. The rates of local control (LC), disease-specific survival, disease-free survival, and overall survival (OS) were calculated using the Kaplan-Meier method. RESULTS: Of the 98 patients, 40 had Stage IIB and 58 had Stage IIIA. The clinical disease stage and N stage were significantly greater in those patients who underwent RT than in those who did not; however, no statistically significant differences were identified in the additional characteristics between those receiving and not receiving RT within each stage or nodal group. The overall 5-year actuarial LC rate was 81% in the RT group and 54% in the chemotherapy/surgery-alone group (p = 0.07). Postoperative RT significantly improved the 5-year LC rate in patients with Stage IIIA disease (from 35% to 82%, p = 0.01). Postoperative RT did not significantly improve the 5-year OS rate (30% with RT vs. 49% without) for all patients or for patients with Stage IIIA disease. The disease-specific survival and disease-free survival rates did not differ between the treatment groups. Patients who responded to induction chemotherapy had a significantly greater 5-year OS rate (49%) than did those with stable or progressive disease (22%, p = 0.003). CONCLUSION: Postoperative RT in patients with Stage IIIA NSCLC treated with induction chemotherapy followed by surgery significantly improved LC without improving OS. Significantly improved survival was observed in all patients who responded to induction chemotherapy compared with those with stable or progressive disease.

Chemotherapy with cisplatin and vinorelbine for elderly patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC)

Background  

Although modest improvements in the survival of patients with non-small cell lung cancer (NSCLC) can be achieved with cisplatin-based chemotherapy (CT), its value is disputed in the geriatric setting. In this study, we evaluate the feasibility of vinorelbine/cisplatin CT for elderly NSCLC patients.
