A randomized study of cisplatin versus cisplatin plus vindesine for non-small cell lung carcinoma.

Between August 1983 and March 1985, a randomized study was conducted that compared cisplatin (CDDP) (80 mg/m2 on day 1) alone with CDDP plus vindesine (VDS) (3 mg/m2 on days 1, 8, and 15) in 160 consecutive patients with inoperable non-small cell lung cancer (NSCLC). There were no complete responses. The response rate for CDDP plus VDS (22 of 77 patients, 29%) was significantly higher than that for CDDP alone (9 of 78 patients, 12%) (P less than 0.05). However, no difference existed in the median duration of response (20 weeks for CDDP plus VDS versus 20 weeks for CDDP alone) or the median survival time (45 weeks for CDDP plus VDS versus 39 weeks for CDDP alone). No significant differences in toxicity were detected between the two arms; myelosuppression, alopecia, and peripheral neuropathy occurred more frequently with CDDP plus VDS and there was one lethal episode of hepatorenal syndrome in the CDDP plus VDS arm. Among the variables Eastern Cooperative Oncology Group (ECOG) performance status (PS), age, sex, stage, weight loss, serum lactate dehydrogenase (LDH) level, albumin level, histologic cell type, and chemotherapy arm, only chemotherapy arm was a significant factor leading to a major response (P = 0.019, multiple logistic regression analysis). The significant predictors of survival were PS (P = 0.000), sex (P = 0.000), and stage (P = 0.002) (Cox's proportional hazards model), with a PS of 0 or 1, female sex, and lower stage yielding the best survival. Although a significantly higher response rate was obtained in the combination arm than in the single agent arm, the survival benefit to patients receiving such combination chemotherapy was not determined and more effective chemotherapy regimens are required.     

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.     

A randomized comparative study of 254-S plus vindesine (VDS) vs. cisplatin (CDDP) plus VDS in patients with advanced non-small cell lung cancer (NSCLC)]

It has been shown in phase II studies that 254-S, a new anticancer platinum complex, is effective in the treatment of various cancers. In order to more objectively evaluate the clinical usefulness of this compound, a randomized comparative study of 254-S plus VDS vs. CDDP plus VDS was conducted in patients with advanced NSCLC. 254-S or CDDP was intravenously administered at 90 mg/m2, at least 2 times at 4-week intervals. VDS was intravenously administered at 3 mg/m2 on Days 1 and 8 of each treatment of 254-S or CDDP. Of 136 patients registered, 121 (64 of the 254-S/VDS group and 57 of the CDDP/VDS group) were evaluable for tumor response (complete cases). There was no significant intergroup difference in the tumor response rate (254-S/VDS group: 12.5% [8/64], CDDP/VDS group: 15.8% [9/57]), nor by cancer staging, histological type or survival. As for toxic effects, leukopenia was significantly less frequent in the 254-S/VDS group while thrombocytopenia was significantly less frequent in the CDDP/VDS group. Nephrotoxicity such as an elevation of BUN and a decrease in serum creatinine was significantly less frequent in the 254-S/VDS group in spite of the lower volume hydration performed. In addition, nausea and vomiting as well as anorexia were observed with significantly lower incidences in the 254-S/VDS group despite the less frequent anti-emetic treatment. Based on these results, it was concluded that combination treatment with 254-S and VDS is a safe and useful regimen for treatment of NSCLC, generating antitumor effects equivalent to the CDDP/VDS regimen.     

Adjuvant chemotherapy of paclitaxel plus carboplatin in uterine corpus cancer--comparison with cisplatin, adriamycin plus cyclophosphamide

The therapeutic efficacy and adverse reactions were compared between 14 patients who received TJ therapy using paclitaxel (PTX) and carboplatin (CBDCA) and 39 who received CAP therapy using cyclophosphamide (CPA), doxorubicin (DXR) and cisplatin (CDDP) as postoperative chemotherapy for cancer of the uterine body. In TJ therapy, PTX (175 mg/m(2)) and CBDCA (AUC 5) were administered on Day 1 (every 3 weeks), while in CAP therapy, CPA (500 mg/m(2)), DXR (40 mg/m(2)) and CDDP (50 mg/m(2)) were administered on Day 1 (every 4 weeks). Grade 3 or more severe hematotoxicity included leukocytopenia (incidence in the TJ and CAP groups: 71.4% and 64.1%, respectively), neutropenia (100%, 87.1%), thrombocytopenia (0%, 12.8%), and anemia (0%, 20.5%). No significant differences were noted between the two groups. Grade 3 or severe non-hematologic toxicities included nausea (0%, 15.4%) and vomiting (0%, 12.8%) with significantly higher incidence in the CAP therapy group (p=0.0000736, p=0.000736), peripheral sensory disturbance (7.1%, 0%) and arthralgia (7.1%, 0%) with significantly higher incidence in the TJ therapy group (p=0.00129, p=0.00000538). The survival rate and disease-free survival rate showed no significant differences between the two groups. TJ therapy is thought to be as effective as CAP therapy, and can be safely conducted, although precautions are required regarding arthralgia and neuropathy.     

Combination chemotherapy of ifosfamide, cisplatin and vindesine for non-small cell lung cancer

Twenty patients with advanced non-small cell lung cancer were treated with a combination chemotherapy consisting of ifosfamide (IFX), cisplatin (CDDP) and vindesine (VDS). The treatment schedule was IFX 1.3 g/m2 i.v., on days 1-5, CDDP 20 mg/m2 i.v., on days 1-5, and VDS 3 mg/m2 i.v., on days 1 & 8, and, in principle, the regimen was repeated every 4 weeks. Of 19 evaluable patients, there were 1 CR, 7 PR, 10 NC and 1 PD, with an overall response rate of 42.1%. The median duration of responses was 7.45 months, and the median survival time of all patients was 13.2 months. The major toxicities occurring were hematologic toxicity, alopecia, gastrointestinal toxicity and peripheral neuropathy. Hematologic toxicity was severe and was judged to be dose limiting, but clinically manageable. These results indicate that this combination chemotherapy is active against non-small cell lung cancer and deserves further studies.     

Treatment of patients with advanced nonsmall cell lung carcinoma using docetaxel and gemcitabine plus granulocyte-colony stimulating factor

BACKGROUND: A combination regimen comprised of docetaxel, gemcitabine, and granulocyte-colony stimulating factor (G-CSF) was studied in patients with advanced nonsmall cell lung carcinoma (NSCLC) to determine its antitumor efficacy and tolerance. METHODS: Thirty-four patients with advanced measurable NSCLC (3 patients with Stage IIIB and 31 patients with Stage IV disease) were treated with an intravenous combination chemotherapy regimen comprised of docetaxel, 80 mg/m(2), on Day 1 and gemcitabine, 1000 mg/m(2), on Days 1 and 10; G-CSF, 5 microg/kg, was administered subcutaneously between Days 2 and 8. Treatment cycles were repeated every 3 weeks. All patients were evaluable for toxicity and response assessment. A total of 163 courses was administered. RESULTS: Objective tumor response was noted in 17 patients (50%; 95% confidence interval, 32. 5-67.5%), including 2 complete responses (6%) and 15 partial responses (44%). There was no change in 10 patients (29%) and 7 patients developed progressive disease. The median duration of response was 6.5 months (range, 3-15 months) and the median time to disease progression for all patients was 6.8 months (range, 1.8-18 months). The median overall survival time was 13.0 months (range, 2. 5-23+ months) with a 1-year survival rate of 55.8%. Myelosuppression was the most frequently encountered adverse reaction, although World Health Organization Grade 3 or 4 leukocytopenia and/or granulocytopenia occurred in only 18% and 24% of patients, respectively. Other toxicities generally were mild to moderate, and always fully reversible. CONCLUSIONS: With a response rate of 50% and a median survival time of 13 months, the drug combination described in the current study appears to have significant activity against advanced metastatic NSCLC. Due to its fairly good tolerance and ease of administration, further investigation of this regimen appears warranted.     

Phase II study of irinotecan and carboplatin for advanced non-small cell lung cancer

A phase II study was conducted to assess the activity and toxicity of irinotecan (CPT-11) and carboplatin (CBDCA) combination chemotherapy for advanced non-small-cell lung cancer (NSCLC). Eligibility included chemo-naive advanced NSCLC patients with measurable disease and a good performance status. CPT-11 of 50 mg/m(2) was administered as a 90-min intravenous infusion on days 1, 8, and 15. CBDCA dosed to an area under the concentration-time curve of 5 mgmin/ml, using Calvert's formula, was administered by 90-min infusion after the CPT-11 infusion on day 1. Treatment was repeated 28 days interval for at least two cycles. Haematopoietic growth factors were not routinely used. From December 1997 to January 1999, 36 patients were entered into the study. The overall response rate was 25.0% (95% confidence interval: 12.1-42.2%). The median survival time and the 1-year survival rate were 10.2 months and 42.2%, respectively. Major toxicity by Japan Clinical Oncology Group criteria was as follows: grade 3-4 neutropenia 76.5%; grade 3 anemia 26.5%; grade 3/4 thrombocytopenia 47.1%; grade 3 nausea/vomiting 36.1%; grade 3-4 diarrhoea 5.9%; grade 3 alopecia 5.9%; grade 3-4 skin rush 2.9%. Four patients developed febrile neutropenia and only one had serious diarrhea induced by CPT-11. Actual relative delivery dose of CPT-11 to the projected one on days 8 and 15 were 0.86 and 0.43, respectively. It seemed that CPT-11 and CBDCA was more toxic regimen than CPT-11 and CDDP in advanced NSCLC. The relatively disappointing response rate could be related with low dose intensity of CPT-11.     

A phase III randomized trial comparing vindesine and cisplatin with or without ifosfamide in patients with advanced non-small-cell lung cancer: long-term follow-up results and analysis of prognostic factors

In order to evaluate the activity and toxicity of a three-drug combination of vindesine, ifosfamide and cisplatin (VIP) for inoperable non-small-cell lung cancer (NSCLC), we conducted a randomized trial comparing VIP with a two-drug combination of cisplatin and vindesine (VP). Between September 1987 and March 1992, a total of 132 patients with stage III or IV NSCLC were randomly allocated to either VIP or VP. The VIP regimen consisted of vindesine (VDS 3 mg/m(2) on days 1 and 8), ifosfamide (IFX 1300 mg/m(2) on days 1-5), and cisplatin (CDDP 20 mg/m(2) on days 1-5). The VP regimen consisted of VDS and CDDP with the same dose and schedule as the VIP regimen. Both regimens were repeated every 4 weeks. Objective response rates were 49.3% (95% confidence interval: 95%CI, 43.1-55.4%) in the VIP arm and 44.6% (95%CI, 38.4-50.2%) in the VP arm; the difference was not significant (P=0.5390). Median response duration, median survival time, and two-year survival rates were 26.5 weeks, 49.6 weeks, and 14.9% in the VIP arm and 28.7 weeks, 37.1 weeks, and 12.3% in the VP arm, respectively. There were also no significant differences between these two treatment arms. In comparison with the VP regimen, however, a survival advantage of the VIP regimen could be confirmed when the data were evaluated with Cox's multivariate analysis (P=0.0131). In both arms, the principal toxicity was myelosuppression, which was significantly more frequent in the VIP arm, although generally well tolerated. CONCLUSION: This study suggested the survival advantage of the VIP regimen over the VP regimen for treatment of patients with advanced NSCLC.     

A phase I and pharmacokinetic study of diamminecyclobutane-dicarboxylatoplatinum (NSC 241240)

Carboplatin (CBDCA; NSC 241240) is a second-generation platinum coordination compound which in preclinical testing was found to be less nephrotoxic and emetogenic than cis-diamminedichloroplatinum (CDDP), while retaining a broad spectrum of antitumor activity. We have conducted a Phase I trial of CBDCA in 38 patients with advanced carcinoma. The drug was given without hydration as a 24-hr constant i.v. infusion on Day 1 of a 28-day cycle. Seventy-five cycles of CBDCA were administered in eight dose levels ranging from 20 to 320 mg/sq m. Dose-limiting toxicity was myelosuppression, primarily thrombocytopenia, occurring between Days 14 and 28 of the cycle. Myelosuppression was first observed at a dose of 240 mg/sq m and became dose-limiting at 320 mg/sq m, which is the recommended dose for Phase II trial. Other toxicities included nausea and vomiting and reversible renal failure seen in two patients with low normal pretreatment creatinine clearances. No consistent changes were seen on serial audiograms. Plasma concentrations of total and ultrafilterable platinum were measured by flameless atomic absorption spectrophotometry. Following cessation of the infusion, a half-life of 170 +/- 34 min (S.D.) was found for CBDCA-derived ultrafilterable platinum. In vitro clonogenic assay of a CDDP-sensitive human ovarian cancer cell line using clinically achievable drug concentrations suggests that prolonged infusions of CBDCA may be more cytotoxic than bolus administration. In this study, minimal responses were seen in two patients with ovarian carcinoma who had failed previous combination chemotherapy including CDDP. In addition, three patients with refractory metastatic breast cancer responded to CBDCA (two minimal responses and one partial response) with remission durations averaging 3 months. CBDCA behaves as predicted by preclinical studies with different toxicities from CDDP and apparent activity in breast cancer.     

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.     

Preliminary results of a phase II study of weekly paclitaxel (PTX) and carboplatin (CBDCA) administered concurrently with thoracic radiation therapy (TRT) followed by consolidation chemotherapy with PTX/CBDCA for stage III unresectable non-small-cell lung cancer (NSCLC)

Concurrent chemoradiotherapy plays an important role in the treatment of unresectable NSCLC. This phase II study was conducted to evaluate the efficacy and toxicity of paclitaxel (PTX) and carboplatin (CBDCA) at a recommended dose, based on other previous phase I studies. Twenty-two unresectable stage III NSCLC patients participated in this trial. Of those 22 patients, 19 were evaluable, with a median age of 57 (with ages ranging between 42 and 74), in stages IIIA/IIIB: 6/13. Every patient displayed adequate organ functions. Treatment consisted of a 1-hour i.v. infusion of 50 mg/m2 of PTX followed by a half-hour infusion of CBDCA AUC 2 administered weekly concurrently with radiation treatment, every first day of those weeks in which the patient underwent radiotherapy. Concurrent thoracic radiation therapy was performed in daily doses of 2 Gy to a total dose of 66 Gy over a period of 6.5 weeks. After completion of chemoradiotherapy, consolidation chemotherapy was administered via a 3-hour i.v. infusion of 175 mg/2 PTX on days 1 and 22, in combination with a 1-hour i.v. infusion of CBDCA AUC 6 on days 1 and 22, q 4 weeks for 4 cycles. The overall response rate was 78.9% (95% CI: 62-87.7) with 5 CR (26.3%), 10 PR (52.6%), 2 SD (15.8%), and 1 PD (5.3%). The median survival rate of the patients was 13.9 months, and the 1-year survival rate was 65.1%. Toxicity was moderate: grade 2 neutropenia was seen in 8, and grade 3 neutropenia in 5 patients. Grade 2 thrombocytopenia was seen in 3 patients, and grade 3 thrombocytopenia was not observed. Nonhematologic toxicities were moderate: esophagitis was the most common, and significant toxicity was noted in this study (89.4%). Grade 1 asthenia/fatigue was observed in 5, and grade 2 asthenia/fatigue in 3 patients; furthermore, grade 1 peripheral neuropathy was seen in 4 of the cases and grade 2 peripheral neuropathy in 3 of the cases. Concurrent chemoradiotherapy with weekly PTX/CBDCA, followed by consolidation chemotherapy with the same regimen in patients with stage III unresectable NSCLC is feasible and well tolerated.     

Fractionated administration of irinotecan and cisplatin for treatment of non-small-cell lung cancer: a phase II study of Okayama Lung Cancer Study Group.

A phase II study of fractionated administration of irinotecan (CPT-11) and cisplatin (CDDP) in patients with non-small-cell lung cancer (NSCLC) was conducted. Between January 1996 and January 1998, 44 previously untreated patients with stage IIIB or IV NSCLC were enrolled. CDDP at a dose of 60 mg x m(-2) was given first and followed by CPT-11 at a dose of 50 mg x m(-2). Both drugs were given by 1-hour infusion on days 1 and 8, and repeated every 4 weeks up to 4 cycles. 42 patients were evaluated for response and 44 for survival and toxicity. 20 patients (48%: 95% confidence interval 32-63%) achieved an objective response. The median duration of responses was 8 months, and the median survival time and the 1-year survival rate were 12.5 months and 56.8%, respectively. Major toxicities were neutropenia and diarrhoea. Grade 3 or 4 neutropenia occurred in 70.5% of the patients and one patient died of sepsis. Grade 3 or 4 diarrhoea was experienced in 25.0%, but manageable by conventional therapy. In conclusion, fractionated administration of CPT-11 and CDDP was highly effective for advanced NSCLC with manageable toxicities.     

Paclitaxel, cisplatin, and gemcitabine combination chemotherapy within a multidisciplinary therapeutic approach in metastatic nonsmall cell lung carcinoma

BACKGROUND: Cisplatin-based chemotherapy combinations improve quality of life and survival in advanced nonsmall cell lung carcinoma (NSCLC). The emergence of new active drugs might translate into more effective regimens for the treatment of this disease. METHODS: The objective of this study was to determine the feasibility, response rate, and toxicity of a paclitaxel, cisplatin, and gemcitabine combination to treat metastatic NSCLC. Thirty-five consecutive chemotherapy-naive patients with Stage IV NSCLC and an Eastern Cooperative Oncology Group performance status of 0-2 were treated with a combination of paclitaxel (135 mg/m(2) given intravenously in 3 hours) on Day 1, cisplatin (120 mg/m(2) given intravenously in 6 hours) on Day 1, and gemcitabine (800 mg/m(2) given intravenously in 30 minutes) on Days 1 and 8, every 4 weeks. Although responding patients were scheduled to receive consolidation radiotherapy and 24 patients received preplanned second-line chemotherapy after disease progression, the response and toxicity rates reported refer only to the chemotherapy regimen given. RESULTS: All the patients were examined for toxicity; 34 were examinable for response. An objective response was observed in 73.5% of the patients (95% confidence interval [CI], 55.6-87.1%), including 4 complete responses (11.7%). According to intention-to-treat, the overall response rate was 71.4% (95% CI, 53. 7-85.4%). After 154 courses of therapy, the median dose intensity was 131 mg/m(2) for paclitaxel (97.3%), 117 mg/m(2) for cisplatin (97.3%), and 1378 mg/m(2) for gemcitabine (86.2%). World Health Organization Grade 3-4 neutropenia and thrombocytopenia occurred in 39.9% and 11.4% of patients, respectively. There was one treatment-related death. Nonhematologic toxicities were mild. After a median follow-up of 22 months, the median progression free survival rate was 7 months, and the median survival time was 16 months. CONCLUSIONS: The combination of paclitaxel, cisplatin, and gemcitabine is well tolerated and shows high activity in metastatic NSCLC. This treatment merits further comparison with other cisplatin-based regimens.     

Phase I trial of the combination of irinotecan, paclitaxel, and carboplatin in patients with advanced non-small-cell lung cancer.

PURPOSE: To determine the maximum-tolerated dose, toxicities, and dose suitable for phase II/III trials of irinotecan (CPT-11) combined with paclitaxel and carboplatin in patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Patients with stage IIIB/IV NSCLC were enrolled to this multicenter, phase I study. The initial regimen was paclitaxel 225 mg/m(2)/3 h, followed by carboplatin area under the curve (AUC) 6 over 30 minutes on day 1, and CPT-11 starting at 40 mg/m(2) over 90 minutes, days 1 and 8, every 3 weeks. Dose-limiting toxicity occurred in three of seven patients. The regimen was amended, with doses reduced to paclitaxel 175 mg/m(2)/3 h, carboplatin AUC 5 and CPT-11 at 40 mg/m(2), all on day 1 every 3 weeks. Dose escalation of CPT-11 proceeded to 80 mg/m(2) then 125 mg/m(2) before dose-limiting toxicities were experienced. Subsequent patients received an intermediate CPT-11 dose of 100 mg/m(2). RESULTS: Thirty-three patients were enrolled; 32 patients were assessable for safety, and 31 were assessable for tumor response. The primary first-cycle dose-limiting toxicities were neutropenia and diarrhea. The most common grade 3/4 toxicity observed during all cycles was neutropenia (16 patients [50%], with six [19%] developing neutropenic fever). Objective tumor response was observed in 39% (12/31, 95% confidence interval, 22% to 58%). The median time to tumor progression was 6.8 months, median survival 11.0 months, and 1-year survival probability 0.46. CONCLUSION: CPT-11 100 mg/m(2), paclitaxel 175 mg/m(2), and carboplatin AUC 5 given every 3 weeks can be safely administered in patients with advanced NSCLC. Neutropenia and diarrhea are the dose-limiting toxicities. The combination shows appreciable activity, and survival data are favorable.     

Temozolomide (TMZ) combined with cisplatin (CDDP) in patients with brain metastases from solid tumors: a Hellenic Cooperative Oncology Group (HeCOG) Phase II study

PURPOSE: To evaluate the efficacy of temozolomide (TMZ) combined with cisplatin (CDDP) in terms of response rate, time to progression (TTP) and overall survival (OS), as well as the tolerability of the regimen in patients with brain metastases from solid tumors. PATIENTS AND METHODS: Patients (n=32) with brain metastases were treated with TMZ 150 mg/m2/day (chemotherapy-pretreated) or 200 mg/m2/day (chemotherapy-naive) for 5 days, combined with CDDP 75 mg/m2 on day 1, every 28 days. Primary tumor sites included breast cancer (n=15), lung cancer (n=12) and other (n=5). Twenty-seven patients had received prior chemotherapy for extracranial disease and 17 had prior radiotherapy to the brain. RESULTS: One patient (3.1%) with non-small cell lung cancer (NSCLC) achieved complete response. Nine patients (28.1%; six with breast cancer, two with melanoma and one with NSCLC) achieved a partial response and five patients (16%) had stable disease. Median OS was 5.5 months and median TTP 2.9 months. One patient died from septicemia/neutropenic fever. Grade III-IV toxicities included anemia (9%), leukopenia (6%), thrombocytopenia (3%), renal toxicity (3%), headache (3%), fatigue (3%), nausea (3%), vomiting (3%), and alopecia (6%). CONCLUSIONS: TMZ combined with CDDP is an active and well-tolerated combination in patients with brain metastases from solid tumors.     

A phase II trial of cisplatin, methotrexate, levofolinic acid, and 5-fluorouracil in the treatment of patients with locally advanced, metastatic squamous cell carcinoma of the head and neck

BACKGROUND: Induction chemotherapy in locoregionally advanced squamous cell carcinoma of the head and neck (SCCHN) might improve survival with respect to radiation therapy alone. Furthermore, chemotherapy represents the only therapeutic option in metastatic head and neck carcinoma. METHODS: To improve further the results that could be obtained with an induction regimen of cisplatin (CDDP) plus 5-fluorouracil (5-FU), the authors treated 50 patients with locally advanced or metastatic SCCHN with a combination of CDDP 65 mg/m2 on Day 1, methotrexate 500 mg/m2 on Day 1, levofolinic acid 250 mg/m2 on Day 2, and 5-FU 800 mg/m2 on Day 2. Cycles were repeated every 2 weeks. The authors' aim was to increase the activity of CDDP plus 5-FU (PF) using a regimen that combined the three most active drugs in SCCHN and provided an adequate biochemical modulation of 5-FU, which was administered as an intravenous bolus infusion. RESULTS: Forty objective responses were observed among 50 evaluable patients (80%; 95% confidence interval [C.I.], 66-90%), including 7 complete responses (14%; 95% C.I., 5-27%), and 33 partial responses (66%; 95% C.I., 51-79%). Locoregional treatment, consisting of radiotherapy or surgery, was given at the end of chemotherapy. On completion of induction chemotherapy and locoregional treatment, 42 of 46 patients (91%) were rendered disease free. After a median follow-up of 20 months, the median duration of response was 10 months, the median failure free survival was 10 months, and the median overall survival was 21 months. The treatment was generally well tolerated. Grade 3-4 neutropenia occurred in 25 patients (50%), but it was febrile in only 3 patients. Nausea and vomiting were well managed with serotonin-3 blocking agents. Severe mucositis was seldom observed and easily manageable, and it never required hospitalization. CONCLUSIONS: The high level of activity, the manageable toxicity, and the noteworthy survival data of this regimen compare favorably with most of the drug combinations used worldwide to treat similar patient populations, with the additional advantage of significantly lower cost.     

Cisplatin combined with carboplatin: a new way of intensification of platinum dose in the treatment of advanced ovarian cancer. Belgian Study Group for Ovarian Carcinoma

We performed a phase I-II trial of escalating doses of cisplatin (CDDP: 50-100 mg/m2 per course) plus carboplatin (CBDCA: 300-400 mg/m2 per course) as a potential way in which to maximize platinum doses without causing excessive toxic effects in patients with advanced ovarian cancer. Thirty-three patients with nonoptimally debulked disease of FIGO (International Federation of Gynecology and Obstetrics) stages IIc-IV [median age: 60 yr; median WHO (World Health Organization) performance status: 2; no prior chemotherapy] received a median of six courses of therapy. CBDCA was infused on day 1 and CDDP on day 2 with an aggressive 48-hour hydration regimen. Myelosuppression was dose-limiting: at the highest dose levels, WHO grade 4 neutropenia and thrombocytopenia led to dose reduction and/or treatment delay in 45% of the patients. Nonhematologic toxic effects included acute nausea and vomiting (97% of the patients), mild alopecia (45%), ototoxic effects (39%), neurotoxic effects (21%), and renal toxic effects (serum creatinine greater than 1.5 mg/dL: 12.5%). The pathologic complete response rate was 22%. We conclude that CBDCA and CDDP can be given safely in combination at reasonably high doses (CBDCA at 300 mg/m2 per course and CDDP at 100 mg/m2 per course) over a 6-month period, provided a close hematologic follow-up is conducted. Randomized clinical trials are needed to define whether this regimen is any better than standard combination chemotherapy.

A phase I trial of the combination of irinotecan (CPT-11) with cisplatin in advanced non-small cell lung cancer (NSCLC) showed a very promising response rate of 54% in previously untreated NSCLC patients. This study was conducted to confirm the activity and toxicities of CPT-11 and cisplatin combination for previously untreated NSCLC in a multi-institutional phase II study. Seventy patients with stage IIIB or IV NSCLC received CPT-11 60 mg m(-2) intravenously (i.v.) on days 1, 8 and 15, and cisplatin 80 mg m(-2) (i.v.) on day 1 every 4 weeks. Assessments were made of response, survival and toxicities. Sixty-nine were eligible, and evaluable for toxicities and survival, and 64 patients evaluable for response. Thirty-three patients (52%; 95% confidence interval 39-64%) achieved an objective response, with one complete response (2%) and 32 partial responses (50%). The median duration of response was 19 weeks and the overall median survival time was 44 weeks. The 1-year survival rate was 33%. The major toxic effects were leucopenia and diarrhoea. Grade 3 or 4 leucopenia, neutropenia, and diarrhoea occurred in 32 patients (46%), 53 patients (80%), and 13 patients (19%) respectively. A combination of CPT-11 and cisplatin is very effective against non-small-cell lung cancer with acceptable toxicities.     

Phase II studies of a single agent and a cis-platinum-based two-drug combination in patients with non-small cell lung cancer

Phase II studies of single agent and CDDP-based two drug combination were performed in 189 patients with inoperable non-small cell lung cancer. Six drug regimens were performed: CDDP alone, VDS alone, Epi-ADM alone, CDDP + VDS, CDDP + CPA, CDDP + ADM. The response rates were 15.4% (6/39) with CDDP alone, 8.0% (2/25) with VDS alone, 6.1% (2/33) with Epi-ADM alone, 26.7% (8/30) with CDDP + VDS, 14.3% (4/28) with CDDP + CPA, 17.6% (6/34) with CDDP + ADM and one CR was performed with CDDP + ADM. In patients with no prior chemotherapy, the response rates were 20.0% (6/30), 11.8% (2/17), 12.5% (2/16), 26.7% (8/30), 16.0% (4/25) and 25.0% (3/12), respectively. The median survival times were 25, 27, 23, 33, 25, and 45 weeks, respectively. The efficacy of CDDP in non-small cell lung cancer patients was re-confirmed, and that of CDDP + VDS, CDDP + ADM was suggested. No death due to toxicity occurred and toxicity was generally tolerable.     

Docetaxel-cisplatin combined chemotherapy in Japanese patients with anthracycline-pretreated advanced breast cancer

The aims of this study were to determine the efficacy of docetaxel (DOC) 60 mg/m(2) and cisplatin (CDDP) 80 mg/m(2) combined chemotherapy in Japanese patients with anthracycline-pretreated advanced breast cancer, and to report the side effects of this therapy. Fourteen patients with anthracycline-pretreated advanced breast cancer were enrolled. DOC was administered at 60 mg/m(2) intravenously over at least 1 h, and then CDDP was administered at 80 mg/m(2) intravenously over at least 3 h. Two courses of this regimen were administered at an interval of 3-4 weeks. Two more courses were administered after 6 months if the disease did not progress, or toxicity was acceptable. The overall response (OR) rate was 64.3%. In the patients with metastases, OR was 58.3%, median duration of the response was 31 weeks (range, 6 to 78 weeks), and median overall survival was 85 weeks (range, 35 to >159). Grade 3/4 toxicities were: neutropenia 10/14; anorexia 5/14; nausea/vomiting 3/14; diarrhea 4/14; oral symptoms 1/14. In conclusion, the combination of DOC (60 mg/m(2)) and CDDP (80 mg/m(2)) is an active regimen that can be relatively safely administered to Japanese patients with anthracycline-pretreated advanced breast cancer.
