Hybrid (intravenous and oral) administration of vinorelbine plus cisplatinum followed by oral vinorelbine as first-line therapy of advanced non-small cell lung cancer: a phase II study

BACKGROUND: The combination of alternate i.v./oral (hybrid) administration of vinorelbine (VNR) plus cisplatin (CDDP), followed by oral VNR, could result in a more suitable first-line regimen for patients (pts) with advanced non-small cell lung cancer (aNSCLC) in the outpatient setting. METHODS: The induction treatment consisted of CDDP 80 mg/m(2) i.v. and VNR 25 mg/m(2) i.v. day 1 and VNR 60 mg/m(2) oral day 8, every 3 weeks for 4 courses. A dose escalation of VNR to 80 mg/m(2) oral from day 8 of the second course and to 30 mg/m(2) i.v. from day 1 of the third course was planned in the absence of G3-4 toxicity. Pts with disease control after 4 courses underwent consolidation treatment with oral VNR 80 mg/m(2) days 1 and 8 every 3 weeks up to intolerance or progression. RESULTS: Fifty-three pts entered the study: 80% males; median age 63 years (range 43-71); median ECOG PS 0 (range 0-1); histotype: adenocarcinoma 59%, epidermoid 31%, undifferentiated 10%; disease stage: IIIB 22%, IV 70%, recurrent disease 8%. The objective response was as follows: 1 (2%) CR, 20 (38%) PR, 16 (30%) SD, 11 (21%) PD and 5 (9%) pts were not assessable. Median TTP and OS were 6 and 10 months, respectively. G3-4 neutropenia was observed in 23 and 24% of pts in the induction and in the consolidation phases, respectively, with febrile neutropenia in 6 pts (11%) and 2 (8%), respectively. G3-4 non-haematological toxicity was rare, being represented by nausea-vomiting and neurotoxicity in 3 pts (6%) in the induction phase. CONCLUSIONS: This combination regimen including hybrid administration of VNR plus CDDP is feasible, tolerable and effective as a first-line treatment in pts with aNSCLC.     

Bi-weekly administration of gemcitabine plus vinorelbine in elderly patients with advanced non-small-cell lung cancer: multicenter phase II trial

PURPOSE: Gemcitabine (GEM) and vinorelbine (VNR) have demonstrated activity as a first-line treatment in elderly patients with advanced non-small-cell lung cancer (NSCLC). We conducted a multicenter phase II trial to evaluate the efficacy and toxicity of bi-weekly administration of GEM plus VNR in elderly patients with advanced NSCLC. PATIENTS AND METHODS: Forty-six chemotherapy-naive elderly (age: >or=70 years) NSCLC patients were enrolled. Patients were eligible if they had histologically or cytologically confirmed unresectable NSCLC with measurable and/or assessable disease. Patients received GEM (1000 mg/m2) and VNR (25 mg/m2) every 2 weeks. RESULTS: The objective response rate of this treatment was 22.7% (95% confidence interval (CI), 10.3-35.1%), median survival time was 310 days, and median time to progression was 133 days. The one-year survival rate was 40.9% (95% CI, 26.3-55.4%), and most adverse events were mild. Only three (6.8%) patients needed to omit GEM because of grade 4 neutropenia or due to physician judgment. No patients suffered treatment-related death. CONCLUSIONS: Bi-weekly administration of GEM plus VNR in elderly patients was an effective, feasible and well-tolerated treatment schedule.     

Phase II study of sequential treatment of advanced non-small-cell lung cancer: three cycles of high-dose epirubicin plus cisplatin followed by weekly vinorelbine

Previous phase I, II, and III studies on high-dose epirubicin (HDEPI), alone or in combination with cisplatin (CP), indicate an interesting activity of this drug in the treatment of non-small-cell lung cancer (NSCLC). However, the toxicological profile of HDEPI limits its prolonged use. In our experience, vinorelbine (VNR) seems to be a suitable drug for long-term monotherapy for advanced NSCLC. On these grounds, advanced NSCLC patients were treated with the following strategy: 3 consecutive cycles of CP 60 mg/m2 and HDEPI 120 mg/m2 on day 1, every 3 weeks; then, irrespective of response, weekly VNR at a dose of 25 mg/m2 was administered at home. From December 1996 to March 1998, 25 patients entered the study. After receiving 3 cycles of CP/HDEPI, 8 patients (32%) had a partial response and 3 (12%) had a minor response. Nine patients had stable disease (36%) and 4 (16%) had progressive disease. Twenty-three patients received weekly VNR, and the median number of administrations was 10 (range, 1-38). After VNR treatment, we observed a partial response in 2 patients who previously had stable disease. Therefore, the overall response rate to sequential treatment was 40%; median time to progression was 7 months (range, 2-26 months). The major toxicities due to the CP/HDEPI regimen were neutropenia (72%) and alopecia (80%). During the VNR treatment, grade 3/4 neutropenia was seen in 36% of patients. The doses and the timing of VNR administrations were modified according to toxicity. Symptoms such as cough, dyspnea, and pain, present in 21 patients before the treatment, improved in 11 cases (52%). Median overall survival is 9 months (range, 3-40+ months); one patient is still alive after 40 months. One- and 2-year survival rates are, respectively, 44% and 16%. This study confirms the activity of CP/HDEPI in NSCLC and indicates that the sequential treatment of CP/HDEPI for 3 cycles followed by weekly VNR could be considered an effective strategy for locally advanced or metastatic NSCLC.     

Cisplatin, gemcitabine, and vinorelbine combination therapy in advanced non-small-cell lung cancer: a phase II randomized study of the Southern Italy Cooperative Oncology Group.

PURPOSE: In a previous phase I study cisplatin (CDDP), gemcitabine (GEM), and vinorelbine (VNR) combination therapy was safe and very active in patients with non-small-cell lung cancer (NSCLC). This study was aimed at better defining the activity and toxicity of this regimen. PATIENTS AND METHODS: One hundred eleven chemotherapy-naive patients, age < or = 70 years, with stage IIIB or IV NSCLC and a performance status of 0 or 1 (Eastern Cooperative Oncology Group scale) were randomized to two treatment arms. Patients on arm A received CDDP 50 mg/m2, GEM 1,000 mg/m2, and VNR 25 mg/m2 on days 1 and 8 of an every-3-weeks cycle (57 patients). Patients on arm B received CDDP 80 mg/m2, epirubicin 80 mg/m2, and vindesine 3 mg/m2, all delivered on day 1 every 4 weeks, plus lonidamine orally 150 mg three times daily (54 patients). In December 1996, randomization was stopped early, and an additional 30 patients were treated with the experimental regimen to obtain a more accurate estimation of its activity rate. RESULTS: Among 87 patients who received the CDDP-GEM-VNR combination, four complete responses (CRs) and 46 partial responses (PRs) were observed, for an overall response rate of 57% (95% confidence interval [CI], 46% to 68%). Two CRs and 18 PRs were recorded among 54 patients on arm B, giving a 37% activity rate (95% CI , 24% to 51%). After a median follow-up duration of 19 months, the median progression-free and overall survival durations were 32 and 50 weeks in arm A, and 18 and 33 weeks in arm B, respectively. World Health Organization grade 3 to 4 neutropenia and thrombocytopenia occurred in 46% and 14% of patients in arm A and in 22% and 11% of those in arm B, respectively. Severe nonhematologic toxicity was uncommon in both arms. CONCLUSION: The CDDP-GEM-VNR combination is a highly effective treatment for patients with advanced NSCLC and has a manageable toxicity. A phase III trial comparing this new combination with both CDDP-VNR and CDDP-GEM regimens is underway.     

Optimization of the schedule of gemcitabine-cisplatin combination as induction regimen for patients with biopsy-proven stage IIIa N2 - stage IIIb non-small-cell lung cancer: a prospective phase-II study

Aim of this study was to define the optimal schedule of gemcitabine (GCB)\cisplatin (CDDP) combination as induction chemotherapy (CHT) in patients with stage IIIa pN2-IIIb non - small-cell lung cancer (NSCLC). Fifty patients with mediastinoscopically-proven stage-IIIa pN2 -IIIb NSCLC were treated with 3 cycles of induction CHT followed by surgery (if staged IIIa) and three-time-daily accelerated radiotherapy. Chemotherapy initially consisted of 3 courses of CDDP 100 mg\m(2) d1 plus GCB 1000 mg\m(2) dd 1,8,15 repeated every 4 weeks, than was modified in CDDP 80 mg\m(2) d1 plus GCB 1250 mg\m(2) dd 1,8 repeated every 3 weeks. Twenty-nine four-week scheduled treatment cycles were firstly administered to 10 patients (pts): treatment-related toxicity, mainly hematological, caused a dose-reduction or treatment omission on day 15 in 65% of cycles. After the protocol was amended, 119 three-week scheduled treatment cycles were administered to 40 pts. Treatment-related toxicity of the new schedule caused a dose-reduction or treatment omission in only 10% of cycles, no patients requiring chemotherapy discontinuation. Thirty-seven out of fifty patients (74%, 95% CI: 60-85%) achieved a partial response, 7 had stable disease and 6 had disease progression. Similar activity was seen with both schedules. One nodal pathological complete remission was observed among the 24 pts who underwent surgery. At present, with a median follow-up of 13 months (mos), 2-year (y) survival of all the 50 pts and of the 24 pts staged IIIa who underwent surgery is estimated as 37% (95% CI: 24-58%) and 47% (95%CI: 27-80%), respectively. When given as induction chemotherapy, a three-week schedule of CDDP plus GCB combination appeared to be effective, with lower toxicity and better compliance than a four-week schedule.     

Pilot combination phase II study of mitomycin C plus cisplatin for non-small cell lung cancer

Fifteen patients (six patients with adenocarcinoma, seven patients with squamous cell carcinoma, and two patients with large cell carcinoma) with advanced non-small cell lung cancer (NSCLC) were evaluable for mitomycin C (MMC; 8 mg/m2 day 1, 8, every 3-4 weeks) plus cisplatin (CDDP; 80 mg/m2 day 1, every 3-4 weeks). Ten patients had had prior chemotherapy. Among 15 evaluable patients, no patient achieved complete response, and two patients showed partial response. The response rate of MMC plus CDDP against NSCLC was 13.3%. Toxic effects included anorexia (80%), nausea and vomiting (67%), leukopenia (53%), anemia (47%), nephrotoxicity (47%), thrombopenia (27%), liver injury (27%), and fever (7%). These toxic effects were reversible and manageable. The combination of MMC and CDDP appears to be valuable regimen against advanced NSCLC.     

Combination of low-dose cisplatin and gemcitabine for treatment of elderly patients with advanced non-small-cell lung cancer

PURPOSE: To evaluate the feasibility, toxicity and efficacy of the combination of low-dose cisplatin (CDDP) and gemcitabine (GEM) in elderly patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: This phase II trial included 46 patients aged 70 years or older with previously untreated advanced NSCLC. All patients were evaluable for response and toxicity. Treatment consisted of CDDP 50 mg/m(2) on day 1 plus GEM 1000 mg/m(2) on days 1 and 8. The regimen was repeated every 21 days. Patients received a minimum of three courses unless progressive disease was detected. RESULTS: A total of 190 GEM-CDDP courses were administered (median 4.1 courses per patient). The chemotherapy regimen was well tolerated. No patients developed grade 4 toxicity. Grade 3 toxicities were as follows: neutropenia in six patients (13%), and anemia, thrombopenia and nausea/vomiting in one (2%) each. Two patients (4%) had mild nephrotoxicity. Of the 46 patients, 16 had a partial response (35%, 95% confidence interval, CI, 28-52%), 17 (37%) remained stable and 13 (28%) had disease progression. Eastern Cooperative Oncology Group performance status improved in 17 patients (37%), whereas 25 (54%, 95% CI 44-74%) showed a clinical benefit. Median time to progression was 20 weeks. Overall median survival was 44 weeks, with a 1-year actuarial survival rate of 35%. CONCLUSIONS: The combination of low-dose CDDP and GEM for elderly patients with advanced NSCLC is an effective and well-tolerated chemotherapeutic approach.     

A phase II trial of weekly paclitaxel and gemcitabine in non-small cell lung cancer patients previously treated with platinum and vinorelbine

This study evaluated the activity and toxicity of a weekly paclitaxel plus gemcitabine combination as second-line treatment in patients with advanced non-small cell lung cancer (NSCLC). Paclitaxel 80 mg/m2 on days 1, 8 and 15 and gemcitabine 1000 mg/m2 on days 1 and 8 every 3 weeks were administered to 34 consecutive, advanced NSCLC patients uniformly pretreated with cisplatin or carboplatin and vinorelbine. The median time interval from first- to second-line treatment was 8 weeks (range 1-72). A total of 124 cycles with a median of 3 cycles per patient were administered (range 1-6). Four patients (12%) achieved a partial response (95% confidence interval: 1-23%), 17 had stable disease (50%) and 12 progressed (37%). Three responses were observed in 14 patients showing disease response or stabilization to previous platinum therapy. The median survival was 28 weeks (range 3-91), the median progression-free survival was 12 weeks (range 3-50) and the 1-year survival rate was 23%. The toxicity profile was favorable. In conclusion, a weekly schedule of paclitaxel plus gemcitabine as a second-line regimen has moderate activity and good tolerability in NSCLC patients not refractory to previous platinum-vinorelbine treatment.     

A phase II trial of oral UFT plus cisplatin (CDDP) in patients with non-small cell lung cancer (NSCLC)

Based on the results of our previous pilot study, we conducted a multi-institutional phase II study of combination chemotherapy consisting of oral UFT (Taiho Pharmaceutical Co. Ltd, Tokyo) plus cisplatin (CDDP) in patients with advanced non-small cell lung cancer (NSCLC). UFT capsule containing 100 mg tegafur and 224 mg uracil was orally administered in two divided doses on days 1 through 21 making the total tegafur dose 400 mg/m(2)/day (maximum 600 mg/body). CDDP was administered by drip infusion at a dose of 20 mg/m(2) on a 5-day schedule from day 8 to 12. Treatment was repeated every 4 weeks as long as the criteria for initiation of therapy were still met. Between April 1995 and March 1997, 51 patients were entered into the study. The mean age of all 50 eligible patients was 64 years(range: 40-78). There were 21 patients with clinical stage IIIB disease and 29 patients with IV disease. Thirty-two patients had adenocarcinoma, 14 had epidermoid carcinoma, and four had large cell carcinoma. Of the 47 assessable patients, 18 achieved a partial response with an overall response rate of 38.3% (95% confidence interval: 24.4-52.2%). The median response duration was 113 days. The median survival time of the eligible patients was 12.8 months, and the 1-year survival rate was 54%. Among the 51 patients enrolled, grade 3 or 4 leukopenia developed in one patient (2%), neutropenia in six patients (11. 8%), thrombocytopenia in six patients (11. 8%), and anemia in three patients (5. 9%). Non-hematological grade 3 or 4 toxicities included anorexia in 10 patients (19.6%), nausea in ten (19.6%), vomiting in two (3.9%), and diarrhea in two (3. 9%). Grade 3 abnormal laboratory data included bilirubinemia in four (7. 8%), GPT elevation in one (2.0%), and hematuria in one (2.0%). In conclusion, combination of CDDP plus oral UFT is efficacious, with low toxicity, in the treatment of advanced NSCLC. In particular, the low hematological toxicity may warrant application of this regimen to the treatment of elderly patients and in trials of concurrent chemoradiotherapy in patients with locally advanced NSCLC.     

Front-line paclitaxel and irinotecan combination chemotherapy in advanced non-small-cell lung cancer: a phase I-II trial

Our purpose was to determine the efficacy of irinotecan plus paclitaxel administered on day 1, repeated every 2 weeks, in untreated patients with advanced or metastatic non-small-cell lung cancer (NSCLC). In total, 56 patients with inoperable or metastatic stage III and IV NSCLC with a histologically or cytologically confirmed diagnosis were enrolled. None of the patients had undergone prior chemotherapy or radiation therapy. Treatment involved irinotecan 125 mg m(-2) and paclitaxel 135 mg m(-2) administered on day 1 and repeated every 2 weeks for a planned number of nine cycles. With a standard dose of paclitaxel at 135 mg m(-2), the dosage of irinotecan was escalated at four levels: 75, 100, 125 and 150 mg m(-2); 125 mg m(-2) was established as the maximum tolerated dose; this dosage was administered to 46 patients. A total of 52 patients (median age 65 years, range 38-77 years) were assessable for toxicity and survival and 46 for response rate. Out of 46 evaluable patients, 19 achieved partial response (41.3%), 17 had stable disease (37%) and 10 (21.7%) experienced disease progression. The median duration of response was 6 months (range 2-9+ months). The main adverse reactions were myelotoxicity (grades 3 and 4) in 10 (19.2%) patients and diarrhoea (grade 3) in four (7.7%) patients. Irinotecan combined with paclitaxel, administered every 2 weeks, appears to be an effective treatment for advanced-stage NSCLC.     

Combination of cisplatin and vinorelbine as adjuvant chemotherapy in non-small cell lung cancer patients--feasibility assessment of 5 consecutively treated patients

Post-operative adjuvant chemotherapy(POAC)combining cisplatin(CDDP)and vinorelbine(VNR)for non-small cell lung cancer(NSCLC)patients is considered as a standard regimen. However, some Japanese investigators point out the toxic profile of this regimen in the practice settings. Thus, five consecutive patients with mean age of 61.6 years old were treated to evaluate the feasibility of this regimen among Japanese patients. Three male and 2 female patients were enrolled, with post-operative stage of IIB/IIIA/IIIB in 1/2/2 patients, respectively. CDDP was administered on day 1 at 80 mg/m(2), and VNR on days 1 and 8 at 25 mg/m(2) intravenously, every 21 days. The regimen was aimed to complete 4 cycles, and 4 patients have completed the treatment without reducing the doses. Average treatment interval was 23 days. Four patients experienced grade(Gr)4 neutropenia, and 1 patient had Gr 3 liver damage. Other mild toxicities included Gr 1 nausea/vomiting in all patients, and Gr 1 GFR reduction in 3 patients. Combination of CDDP and VNR seems to be tolerable in terms of POAC, with relatively mild toxicity profile similar to the previous reports.     

Phase II trial of cisplatin, etoposide, and 5-fluorouracil in advanced non-small-cell lung cancer: an Eastern Cooperative Oncology Group Study (PB586)

Advanced non-small-cell lung cancer (NSCLC) remains an incurable disease despite significant progress in chemotherapy. We conducted a phase II clinical trial to investigate the efficacy and toxicity of a cisplatin, etoposide, and 5-fluorouracil (5-FU) combination in advanced metastatic and/or recurrent NSCLC. Forty patients with advanced, recurrent, or metastatic, measurable NSCLC were treated with cisplatin, 60 mg/m2 intravenously (i.v.) on day 1; etoposide, 120 mg/m2/day i.v. on days 1, 2, and 3; and 5-FU. 1,000 mg/m2/day i.v. continuous infusion on days 1 through 5. Treatment was administered in 4-week cycles. Thirty patients had distant metastases and were previously untreated, and 10 patients had recurrent disease after prior treatment with either surgery (1 patient), radiation therapy (5 patients), or both treatments (4 patients). Twenty-nine patients were evaluable for response. Seven (24%) patients achieved a partial remission (PR), 18 (62%) had stable disease (SD), and 8 (14%) had progressive disease (PD). Overall median survival was 7.9 months (range, 0.4-27.4 months). Patients who achieved a PR had a median survival of 23.5 months (9.3-27.4 months). In contrast, patients with SD had a median survival of 9.9 months (2.5-25.3 months), and patients with PD had a median survival of 2.1 months (1-9.3 months). Median duration of response of 27.1 weeks (4.9-76.5 weeks) for patients with PR, and time to progression was 13.4 weeks (3.7-54.5 weeks) for patients with SD. Toxicity was primarily hematologic and gastrointestinal, and there were three deaths due to infection. The combination of cisplatin, 5-FU, and etoposide as administered in this study appears to have considerable toxicity and does not appear to be superior to other cisplatin-containing regimens used for the treatment of advanced NSCLC.     

A phase II trial of the combination of gemcitabine, ifosfamide and cisplatin in the treatment of advanced non-small cell lung cancer

OBJECTIVE: This phase II trial was designed to assess the efficacy and toxicity profile of the combination of gemcitabine, ifosfamide and cisplatin (GIP) in the treatment of patients with locally advanced or metastatic non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Patients included in the study were those with surgically unresectable or metastatic NSCLC, with bidimensionally measurable disease, a Karnofsky performance status > 60, and who had not received previous chemotherapy. Treatment consisted of 1000 mg/m(2) gemcitabine on days 1 and 8, 3 g/m(2) ifosfamide on day 1, and 50 mg/m(2) cisplatin on day 1, administered in 21-day cycles. A maximum of six cycles were administered. RESULTS: Between March 1996 and December 1997, 60 patients were included in the study (37 stage III and 23 stage IV), of which 59 were evaluated for response. An objective response was obtained in 43% of patients (3% complete and 40% partial responses), whereas 22% had stable disease. The median survival time for the whole group was 52 weeks (65 weeks in patients with stage III, and 35 weeks in stage IV). The most frequent toxicity was haematological, 56% of patients presented grade 3 or 4 myelotoxicity in one of the cycles, although only seven episodes of febrile neutropenia were recorded in the 255 cycles administered. CONCLUSIONS: The GIP regimen attains response rates similar to those obtained with the gemcitabine plus cisplatin combination used in advanced NSCLC, and had an acceptable toxicity profile.     

Efficacy of the combination of cisplatin with either gemcitabine and vinorelbine or gemcitabine and paclitaxel in the treatment of locally advanced or metastatic non-small-cell lung cancer: a phase III randomised trial of the Southern Italy Cooperative Oncology Group (SICOG 0101).

BACKGROUND: Triplet regimens were occasionally reported to produce a higher response rate (RR) than doublets in locally advanced or metastatic non-small-cell lung cancer (NSCLC). This trial was conducted to assess (i) whether the addition of cisplatin (CDDP) to either gemcitabine (GEM) and vinorelbine (VNR) or GEM and paclitaxel (PTX) significantly prolongs overall survival (OS) and (ii) to compare the toxicity of PTX-containing and VNR-containing combinations. PATIENTS AND METHODS: Stage III or IV NSCLC patients were randomly assigned to (i) GEM 1000 mg/m(2) and VNR 25 mg/m(2) on days 1 and 8 (GV arm); (ii) GEM 1000 mg/m(2) and PTX 125 mg/m(2) on days 1 and 8 (GT arm); (iii) GV plus CDDP 50 mg/m(2) on days 1 and 8 (PGV arm); and (iv) GT plus CDDP 50 mg/m(2) on days 1 and 8 (PGT arm). Treatments were repeated every 3 weeks for a maximum of six cycles. RESULTS: A total of 433 (stage III, 160; stage IV, 273) patients were randomly allocated to the study. RR was 48% [95% confidence interval (CI), 42% to 54%] for triplets and 35% (95% CI, 32% to 38%) for doublets (P = 0.004). Median progression-free survival (6.1 versus 5.5 months, P = 0.706) and median OS (10.7 versus 10.5 months, P = 0.379) were similar. CDDP significantly increased the occurrence of severe neutropenia (35% versus 13%), thrombocytopenia (14% versus 4%), anaemia (9% versus 3%), vomiting (6% versus 0.5%), and diarrhoea (6% versus 2%). Conversely, frequency of severe neutropenia (30% versus 17%) and thrombocytopenia (11% versus 6%) was significantly higher with VNR-containing regimens. CONCLUSIONS: Adding CDDP to GV or GT significantly increased RR, but did not prolong the OS of patients. Among doublets, the GT regimen should be preferred in view of its better safety profile.     

An early phase II trial combining cisplatin, carboplatin and vindesine in patients with inoperable non-small cell lung cancer

We conducted an early phase II trial of advanced non-small cell lung cancer (NSCLC) to evaluate the response efficacy of a combination of cisplatin (CDDP), carboplatin (CBDCA) and vindesine (VDS). The twenty-four patients in the study had had no previous treatment. CDDP (15 mg/m2), CBDCA (200 mg/m2) and VDS (3 mg/m2) were administered on Day 1, CDDP (15 mg/m2) was administered on Days 2-5, and VDS (3 mg/m2) was administered on Day 8. We observed 9 partial responses (PR), with a total response rate of 39%. The overall median survival was 72 weeks, and the 1-year survival rate was 57%. Major toxicities were hematologic; leukopenia of grades 3 and 4 occurred in 25% patients, and thrombocytopenia occurred in 21%. Therefore, the combination of CBDCA with CDDP and VDS chemotherapy was effective against inoperable NSCLC with tolerable toxicities and a favorable median survival time.     

Multicentre randomised phase III study comparing the same dose and schedule of cisplatin plus the same schedule of vinorelbine or gemcitabine in advanced non-small cell lung cancer

This study compares two cytotoxic regimens comprising the same dose and schedule of cisplatin (CP) plus vinorelbine (VNR) or gemcitabine (GEM) administered under the same schedule to patients with advanced non-small cell lung cancers (NSCLC). From April 1998 to February 2003, 285 patients were randomised to receive either VNR 25 mg/m(2) on days 1 and 8 as an intravenous (i.v.) bolus plus CP 75 mg/m(2) on day 1 (regimen A) or GEM 1200 mg/m(2) on days 1 and 8 as an i.v. 30-min infusion plus CP 75 mg/m(2) on day 1 (regimen B). Both treatments were recycled every 21 days. If no progression had occurred after six cycles, the patients continued to receive VNR or GEM monochemotherapy weekly. Cross-over of the two single agents was considered if disease progression occurred. Objective response (OR), time to progression (TTP) and overall survival (OS) were analysed according to the intention-to-treat principle. 272 patients were ultimately eligible (137 on A and 135 on B). Their main characteristics were: male/female ratio 214/58; median age 63 (range 32-77) years; median Karnofsky Performance Status (PS) 80 (range 70-100); stage IIIB 34%, stage IV 61%, recurrent disease 5%; histology - epidermoid 29%, adenocarcinoma 53%, other NSCLC 18%. The characteristics of the patients in the two arms were well matched. The following response rates were observed in regimens A and B, respectively: complete response (CR) 0.7% and 3.7%, partial response (PR) 31.9% and 22.2% (P = 0.321). Median CR+PR duration was 8 months in both arms. Clinical benefit represented by an improvement in symptoms was evident in 25.7% and 28.1%, respectively. Median TTP was 5 months in both arms and median OS 11 months in both arms. Grade III-IV neutropenia occurred in 30.7% and 17.7% of the patients in arms A and B, respectively (P = 0.017); thrombocytopenia occurred in 0% and 9.3% (P = 0.004), respectively. No difference in the incidence of anaemia was observed. Non-haematological toxicity was generally mild: a higher incidence of grade 1-2 peripheral neurotoxicity and grade 1-2 local toxicity with regimen A and grade 1-2 liver toxicity with regimen B was reported. A pharmaco-economic comparison showed a difference between the two doublets, principally due to the different costs of VNR and GEM. Under the study conditions the combination of VNR or GEM with the same dose and schedule of CP produced similar OR, clinical benefits, TTP and OS in advanced NSCLC, and only mild toxicological differences were observed. Pharmaco-economic evaluation favoured the CP + VNR doublet.     

A randomized trial of three cisplatin-containing regimens in advanced non-small-cell lung cancer (NSCLC): a study of the Umbrian Lung Cancer Group

Survival in patients with locally advanced (stage III Mo) and metastatic (Ml) non-small-cell lung cancer (NSCLC) is short. Phase II studies have reported objective responses ranging from 20% to 60% using cisplatin-based chemotherapeutic regimens, yet few have shown improvement in median survival. In our phase II pilot studies with cisplatin (CDDP) and etoposide (VP-16), we observed a 26% response rate; with CDDP, VP-16, and mitomycin-C, a 38% response rate was obtained in advanced NSCLC patients. A total of 156 consecutive patients with locally advanced and metastatic NSCLC were randomized to one of three treatment arms to determine whether the chemotherapy protocols had any effect on response rate and median survival in a large, randomized study. Arm 1 consisted of CDDP (120 mg/m2 x 3 weeks); arm 2, of CDDP (120 mg/m2) and VP-16 (100 mg/m2 given i.v. on days 1-3), repeated every 3 weeks; and arm 3, of CDDP (120 mg/m2) and VP-16 (100 mg/m2 on days 1-3) given every 3 weeks, plus mitomycin C (10 mg/m2 on days 1, 21, and 42, then every 6 weeks, for a maximal dose of 100 mg). After 71 patients had been enrolled in the study, we stopped accrual in the CDDP arm due to a lack of response [1 complete response (CR) in 24 patients; 4%] and continued enrollment in the two combination-chemotherapy arms. In the CDDP/VP-16 arm a 30% response rate [1 CR, 18 partial responses (PRs)] was obtained, and in the CDDP/VP-16 mitomycin C arm a 26% response rate (4 CRs, 11 PRs) was seen among a total of 150 evaluable patients. Responses were observed in 31% of patients with favorable performance status (PS) (ECOG 0-1) vs 14% in patients with a poor PS (ECOG 2-3). Of patients with locally advanced disease (III Mo), 17 (33%) obtained an objective response, compared with 20 patients (20%) with metastatic disease. Median survival was 18 weeks in the CDDP arm, 35 weeks in the CDDP/VP-16 arm, and 37 weeks in the CDDP/VP-16/mitomycin C arm. The median survival in the multimodal chemotherapy arms was significantly greater than that obtained with CDDP alone. Toxicity was predominantly myelosuppression in the mitomycin C-containing arm (27%, wtto grade 3-4). Our study shows that combination chemotherapy using CDDP/VP-16 is active and safe in the treatment of advanced NSCLC patients with a good performance status. The addition of mitomycin C did not improve the therapeutic response.     

A randomized study comparing cisplatin or carboplatin with etoposide in patients with advanced non-small-cell lung cancer: European Organization for Research and Treatment of Cancer Protocol 07861

The European Organization for Research and Treatment of Cancer (EORTC) Lung Cancer Working Party conducted a randomized trial comparing cisplatin (CDDP; 120 mg/m2, day 1) and carboplatin (CBDCA; 325 mg/m2, day 1) in combination with etoposide (VP16; 100 mg/m2, days 1, 2, and 3) in advanced non-small-cell lung cancer (NSCLC). Two hundred twenty-eight patients were eligible for survival and 202 assessable for response. We obtained 27 of 100 objective responses (ORs; 27%) in the CDDP arm and 16 of 102 (16%) in the CBDCA arm (P = .07). There was no significant difference in survival. Toxicity, consisting mainly of myelosuppression and renal function impairment, was significantly increased in the patients receiving the CDDP treatment. We conclude that CDDP plus VP16 was more active but also more toxic than CBDCA plus VP16 in advanced NSCLC.

Phase II study of cis-diamminedichloroplatinum in patients with non-small cell lung cancer

A phase II study of cis-diamminedichloroplatinum (CDDP, 80 mg/m2, every 3 weeks) was performed in patients with non-small cell lung cancer (NSCLC). The overall response rate to CDDP was 14% (6/42). In patients without prior chemotherapy, the response rate was 20% (2/10), and in patients with prior chemotherapy, the response rate was 13% (4/31). The major side effect was gastrointestinal toxicity. It was concluded that CDDP at a dose of 80 mg/m2 every 3 weeks is effective against NSCLC.
