Irinotecan plus gemcitabine results in no survival advantage compared with gemcitabine monotherapy in patients with locally advanced or metastatic pancreatic cancer despite increased tumor response rate.

PURPOSE: This phase III, randomized, open-label, multicenter study compared the overall survival associated with irinotecan plus gemcitabine (IRINOGEM) versus gemcitabine monotherapy (GEM) in patients with chemotherapy-naive, locally advanced or metastatic pancreatic cancer. PATIENTS AND METHODS: IRINOGEM patients received starting doses of gemcitabine 1,000 mg/m2 and irinotecan 100 mg/m2 given weekly for 2 weeks every 3-week cycle. GEM patients received gemcitabine 1,000 mg/m2 weekly for 7 of 8 weeks (induction) and then weekly for 3 of 4 weeks. The primary end point of the trial was survival. Secondary end points included tumor response, time to tumor progression (TTP), changes in CA 19-9, and safety. RESULTS: In each arm, 180 randomly assigned patients comprised the intent-to-treat population evaluated for efficacy; 173 IRINOGEM and 169 GEM patients were treated. Median survival times were 6.3 months for IRINOGEM (95% CI, 4.7 to 7.5 months) and 6.6 months for GEM (95% CI, 5.2 to 7.8 months; log-rank P =.789). Tumor response rates were 16.1% (95% CI, 11.1% to 22.3%) for IRINOGEM and 4.4% (95% CI, 1.9% to 8.6%) for GEM (chi2 P <.001). Median TTP was 3.5 months for IRINOGEM versus 3.0 months for GEM (log-rank P =.352). However, subset analyses in patients with locally advanced disease suggested a TTP advantage with IRINOGEM versus GEM (median, 7.7 v 3.9 months). CA 19-9 progression was positively correlated with tumor progression. The incidence of grade 3 diarrhea was higher in the IRINOGEM group but grade 3 to 4 hematologic toxicities and quality-of-life outcomes were similar. CONCLUSION: IRINOGEM safely improved the tumor response rate compared with GEM but did not alter overall survival.     

Phase II study of capecitabine and cisplatin combination as first-line chemotherapy in Chinese patients with metastatic nasopharyngeal carcinoma

PURPOSE: Cisplatin combined with 5-fluorouracil (5-Fu) is widely used in the management of advanced nasopharyngeal carcinoma (NPC). However, catheters and pumps are necessary for the continuous infusion of 5-Fu, which add to the cost, immobility and inconvenience of treatment. Capecitabine, an oral fluoropyrimidine, is a potentially more active and more convenient substitute to 5-Fu. A phase II study was conducted to evaluate the efficacy and safety of a capecitabine and cisplatin combination in metastatic NPC. PATIENTS AND METHODS: In the multicenter, open-label, single-arm phase II study, patients with metastatic NPC who previously received no palliative chemotherapy were enrolled. Patients received oral capecitabine (1,000 mg/m(2) twice daily from day 1 to 14) and intravenous cisplatin (80 mg/m(2), day 1) every 3 weeks. RESULTS: A total of 48 patients were enrolled and included in the intention-to-treat analysis of efficacy and adverse events. There were 3 patients (6.3%) with complete response and 27 patients (56.3%) with partial response, giving an overall response rate of 62.5% (95% CI, 49.1-76.4%). The median duration of response in the 30 responding patients was 7.5 months (range 1.4-22.4 months). With a median follow-up period of 13.3 months (range 2.3-50 months), the median time to progression and median overall survival for all patients were 7.7 months (95% CI, 6.3-9.2 months) and 13.3 months (95% CI, 9.4-17.2 months), respectively. Toxicities were moderate and manageable. Grade 3/4 toxicities included neutropenia (14.6%), anemia (4.2%) and thrombocytopenia (2.1%), nausea (8.3%), vomiting (10.4%), diarrhea (8.3%), stomatitis (6.3%) and hand-foot syndrome (HFS) (4.2%). CONCLUSIONS: The combination of capecitabine and cisplatin is active and well tolerated as a first-line therapy for patients with metastatic NPC.     

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 role for neoadjuvant gemcitabine plus cisplatin in muscle-invasive urothelial carcinoma of the bladder: a retrospective experience

BACKGROUND: Neoadjuvant cisplatin-based chemotherapy improves survival in muscle-invasive urothelial cancer, with MVAC (methotrexate, vinblastine, doxorubicin and cisplatin) considered the standard regimen. Gemcitabine plus cisplatin (GC) has similar efficacy and less toxicity than MVAC in metastatic disease, but is untested as neoadjuvant treatment. METHODS: The authors retrospectively evaluated patients with muscle-invasive urothelial carcinoma who received neoadjuvant GC before radical cystectomy between November 2000 and December 2006 at Memorial Sloan-Kettering Cancer Center. Post-therapy pathological downstaging to either residual disease at cystectomy (pT0) or no residual muscle-invasion (相似文献   

A phase II randomized study evaluating the addition of iniparib to gemcitabine plus cisplatin as first-line therapy for metastatic non-small-cell lung cancer

BackgroundIniparib is a novel anticancer agent initially considered a poly (ADP-ribose) polymerase (PARP) inhibitor, but subsequently shown to act via non-selective protein modification through cysteine adducts. This randomized phase II study investigated the addition of iniparib to gemcitabine–cisplatin in metastatic non-small-cell lung cancer (NSCLC) patients.Patients and methodsPatients with histologically confirmed stage IV NSCLC were randomized 2 : 1 to receive gemcitabine (1250 mg/m², days 1/8) and cisplatin (75 mg/m², day 1) with [gemcitabine/cisplatin/iniparib (GCI)] or without [gemcitabine/cisplatin (GC)] iniparib (5.6 mg/kg, days 1/4/8/11) every 3 weeks for six cycles. The primary end point was the overall response rate (ORR). Secondary objectives included progression-free survival (PFS), overall survival (OS), and safety. The study was not designed for formal efficacy comparison, the control arm being to benchmark results against the literature.ResultsOne hundred and nineteen patients were randomized (39 GC and 80 GCI). More GCI patients were male (80% GCI and 67% GC) and had PS 0 (61% GCI and 49% GC). The ORR was 25.6% [95% confidence interval (CI) 13.0%–42.1%] with GC versus 20.0% (95% CI 11.9%–30.4%) with GCI, which did not allow rejection of the null hypothesis (ORR with GCI ≤20%; P = 0.545). Median PFS was 4.3 (95% CI 2.8–5.6) months with GC and 5.7 (95% CI 4.6–6.6) months with GCI (hazard ratio 0.89, 95% CI 0.56–1.40). Median OS was 8.5 (95% CI 5.5 to not reached) months with GC, and 12.0 (95% CI 8.9–17.1) months with GCI (hazard ratio 0.78, 95% CI 0.48–1.27). More GCI patients received second-line treatment (51% GC and 68% GCI). Toxicity was similar in the two arms. Grade 3–4 toxicities included asthenia (28% GC and 8% GCI), nausea (3% GC and 14% GCI), and decreased appetite (10% in each).ConclusionsAddition of iniparib to GC did not improve ORR over GC alone. The GCI safety profile was comparable to GC alone. Imbalances in PS and gender distribution may have impacted study results regarding PFS and OS.Trial RegistrationClinicalTrial.gov Identifier NCT01086254.     

Functional polymorphisms of the microsomal epoxide hydrolase gene: a reappraisal on a early-onset lung cancer patients series

As concomitant chemoradiotherapy for stage III NSCLC is associated with survival advantage in comparison to a sequential approach, we conducted a phase III randomised study aiming to determine the best sequence and safety of chemotherapy (CT) and chemoradiotherapy (CT-RT), using a regimen with cisplatin (CDDP), gemcitabine (GEM) and vinorelbine (VNR). Unresectable stage III NSCLC patients received CDDP (60 mg/m(2)), GEM (1g/m(2), days 1 and 8) and VNR (25mg/m(2), days 1 and 8) with reduced dosage of GEM and VNR during radiotherapy (66Gy). Two cycles of CT with radiotherapy followed by two further cycles of CT alone were administered in arm A or the reverse sequence in arm B. The study was prematurely closed for poor accrual due to administrative problems. Forty-nine eligible patients were randomised. Response rates and median survival times were, respectively 57% (95% CI: 36-78%) and 17 months (95% CI: 9.3-24.6 months) in arm A and 79% (95% CI: 64-94%) and 23.9 months (95% CI: 13.3-34.5 months) in arm B (p>0.05). Chemotherapy dose-intensity was significantly reduced in arm A. Grade 3-4 oesophagitis occurred in 5 patients. One case of grade 5 radiation pneumonitis was observed. In conclusion, chemoradiotherapy with CDDP, GEM and VNR appears feasible as initial treatment or after induction chemotherapy. Consolidation chemoradiotherapy seems less toxic with a better observed response rates and survival although no valid conclusion can be drawn from the comparison of both arms.     

Induction with mitomycin C, doxorubicin, cisplatin and maintenance with weekly 5-fluorouracil, leucovorin for treatment of metastatic nasopharyngeal carcinoma: a phase II study.

The combination of cisplatin and 5-fluorouracil (5-FU) (PF) is the most popular regimen for treating metastatic nasopharyngeal carcinoma (NPC) but it is limited by severe stomatitis and chronic cisplatin-related toxicity. A novel approach including induction with mitomycin C, doxorubicin and cisplatin (MAP) and subsequent maintenance with weekly 5-FU and leucovorin (FL) were designed with an aim to reduce acute and chronic toxicity of PF. Thirty-two patients of NPC with measurable metastatic lesions in the liver or lung were entered into this phase II trial. Mitomycin C 8 mg m(-2), doxorubicin 40 mg m(-2) and cisplatin 60 mg m(-2) were given on day 1 every 3 weeks as initial induction. After either four courses or remission was achieved, patients received weekly dose of 5-FU 450 mg m(-2) and leucovorin 30 mg m(-2) for maintenance until disease progression. With 105 courses of MAP given, 5% were accompanied by grade 3 and 0% were accompanied by grade 4 stomatitis. The dose-limiting toxicity of MAP was myelosuppression. Forty per cent of courses had grade 3 and 13% of courses had grade 4 leukopenia. No grade 3 or 4 cisplatin-related toxicity was observed. The overall response rate was 94% (95% confidence interval (CI) 84.9-100%) with a complete response rate (CR) of 6% (95% CI: 0-15.2%) and a good partial response (PR) rate of 28% (95% CI 11.7-44.6%), which was optionally defined as observance of only equivocal lesion identifiable under imaging study. Twenty-seven cases entered weekly FL maintenance phase. The median duration of maintenance with weekly FL was 38 weeks (8-91 weeks). There was no grade 3 or 4 toxicity noted during weekly FL. The median progression-free survival and overall survival were 11.6+/-0.4 and 18.1+/-3.6 months respectively. Six patients with a median follow-up of 19.8 months (9.6-41.0 months) were still alive and five of them had disease under control with FL. Good responders (CR and good PR) had better survival than less satisfactory responders (PR and stable disease) (P = 0.05). From Cox's multivariate regression analysis, the only significant prognostic factor for survival was good response to MAP (P = 0.042). Liver metastasis was the only significant variable in the best subset regression model that predicted good response to MAP (CR and good PR) (P = 0.027). MAP was an effective combination for metastatic NPC with minimal stomatitis and cisplatin-related toxicity but had significant myelosuppression. Weekly FL was a maintenance therapy with minimal side-effects. The response rate and overall survival of MAP-FL were better than series previously reported even when a subset of patients with poor prognosis was selected. MAP-FL's role as neoadjuvant or adjuvant therapy is worthy of further study.     

Gemcitabine, vinorelbine and cisplatin combination chemotherapy in advanced non-small cell lung cancer: a phase II trial

The purpose of this phase II trial was to investigate the efficacy and safety of a combination chemotherapy with gemcitabine, vinorelbine and cisplatin in the first-line treatment of advanced non-small cell lung cancer (NSCLC). Patients with NSCLC stage IIIB or IV disease received 1000 mg/m(2) gemcitabine and 25 mg/m(2) vinorelbine on days 1 and 8 and 75 mg/m(2) cisplatin on day 2, every 3 weeks. From December 1998 to May 1999, 31 patients (21 stage IV and 10 stage IIIB disease), with a median age of 59 years (range 40-72 years) were enrolled. The overall intent-to-treat response rate was 45% (95% confidence interval (CI): 27-64%) with 2 complete responders (CR) and 12 partial responders (PR), 7 patients had stable disease and 10 progressed. Median survival was 12.8 months (95% CI: 6.5-12.8+ months), median time to progression was 5.1 months (95% CI: 3.5-7.7 months), and the 1-year survival rate was 52.9% (95% CI: 36.7-76.2%). Patients with stage IIIB disease had a significantly longer overall survival than patients with stage IV disease (P=0.05). Transient World Health Organization (WHO) grade IV leucopenia, anaemia and thrombocytopenia occurred in 3 (10%), 2 (6%) and 3 (10%) patients, respectively. The predominant non-haematological toxicities were alopecia and nausea/vomiting. 15 patients (48%) had WHO grade II and III alopecia and 14 patients (45%) nausea/vomiting. The combination of gemcitabine, vinorelbine and cisplatin has demonstrated major antitumour efficacy in advanced NSCLC with a manageable toxicity profile.     

A phase II study of paclitaxel plus cisplatin chemotherapy in an unfavourable group of patients with cancer of unknown primary site

OBJECTIVE: We evaluated the efficacy and toxicity of combined paclitaxel and cisplatin chemotherapy in patients with cancer of unknown primary site (CUP). Efficacy was evaluated in terms of response rate, progression-free survival and overall survival. METHODS: Thirty-seven patients with CUP were enrolled between January 2001 and September 2003 at Korea Cancer Center Hospital. The patients received 21-day cycles of paclitaxel (175 mg/m(2) i.v.) with cisplatin (60 mg/m(2) i.v.) given on the first day. RESULTS: Of the 37 patients, 31 had adenocarcinoma subtypes. The overall response rate of 26 patients with measurable lesions was 42% [95% confidence interval (CI) 23-61%]. Stable disease was seen in six patients and progressive disease in nine. Median time to progression was 4 months (95% CI 1.3-6.8). Median overall survival was 11 months (95% CI 8.3-13.5). The major toxicities were neuropathy and neutropenia. Grade 4 neutropenia occurred in 10 patients, but febrile neutropenia was seen in four. CONCLUSIONS: This combined paclitaxel and cisplatin regimen was well tolerated with an encouraging level of effectiveness for patients with CUP.     

Doxorubicin and cisplatin chemotherapy in high-grade spindle cell sarcomas of the bone, other than osteosarcoma or malignant fibrous histiocytoma: a European Osteosarcoma Intergroup Study

There are limited data that define the role of chemotherapy in the treatment of high-grade spindle cell sarcomas of bone, other than osteosarcoma or malignant fibrous histiocytoma (MFH-B). This prospective study evaluates the effect of doxorubicin and cisplatin on these tumours. Thirty-seven patients, age 65 years, with spindle cell sarcoma of bone, except osteosarcoma or MFH-B, were included. Chemotherapy consisted of doxorubicin and cisplatin every 3 weeks for six cycles. Resection was performed after three cycles. In 15 patients with metastases, response assessment showed three complete responses (CR), four stable disease (SD), five progression; three were not evaluable. Median time to progression was 30 months (95% Confidence Interval (CI), 8-51 months) for the operable non-metastatic patients; median survival 41 months (95% CI, 16-82 months). Median time to progression in the metastatic group was 10 months (95% CI, 0-18 months) and median survival was 14 months (95% CI, 4-45 months). This study suggests a limited role for doxorubicin and cisplatin in metastatic high-grade spindle cell sarcoma of bone, other than osteosarcoma or MFH-B cases.     

A phase II trial of S-1 and cisplatin in patients with metastatic or relapsed biliary tract cancer.

BACKGROUND: Optimal chemotherapy for advanced biliary tract cancer (BTC) is yet to be defined. We carried out this study to evaluate the efficacy and toxicity of combination chemotherapy with S-1 and cisplatin in metastatic or relapsed BTC. PATIENTS AND METHODS: Patients with pathologically proven BTC were eligible. The chemotherapy regimen consisted of S-1 (40 mg/m(2) p.o. b.i.d. from D1-14) and cisplatin (60 mg/m(2) on D1), repeated every 3 weeks. RESULTS: Fifty-one BTC patients (metastatic:relapsed = 37:14, Gall-bladder:intrahepatic bile ducts:extrahepatic bile ducts = 16:25:10) were enrolled from January 2005 to December 2006. Median age was 57 years (range, 31-71) and most patients had a good performance status. The overall response rate was 30% [95% confidence interval (CI), 17.3-42.7] and complete response was observed in two patients (4%), partial response in 13 (26%), stable disease in 21 (42%), and progressive disease in 9 (18%). With a median follow-up of 12.4 months, the median time to progression was 4.8 months (95% CI, 3.3-6.3) and median overall survival was 8.7 months (95% CI, 6.0-11.4). Major toxic effects were grade 3/4 neutropenia (8.9% of all cycles) and febrile neutropenia was observed in six cycles (2.7% of all cycles). CONCLUSION: Combination chemotherapy with S-1 and cisplatin was a moderately effective outpatient-based regimen in BTC patients. Toxic effects were moderate but manageable.     

First-line chemotherapy with cisplatin plus fractionated temozolomide in recurrent glioblastoma multiforme: a phase II study of the Gruppo Italiano Cooperativo di Neuro-Oncologia.

PURPOSE: Cisplatin and temozolomide (TMZ) are active in glioblastoma multiforme (GBM), with different profiles of toxicity. A bid regimen of TMZ achieves a strong inhibition of O(6)-alkylguanine DNA-alkyl transferase (AGAT), and cisplatin reduces AGAT activity in vitro, suggesting a possible synergic interaction. The primary end point of the present multicenter phase II study was progression-free survival (PFS) at 6 months (PFS-6); secondary end points included response, toxicity, and overall survival. PATIENTS AND METHODS: Chemotherapy-naive patients with GBM who experienced disease recurrence or progression after surgery and standard radiotherapy were eligible. Chemotherapy cycles consisted of cisplatin 75 mg/m(2) on day 1, TMZ 130 mg/m(2) bolus followed by nine doses of 70 mg/m(2) every 12 hours (total of 5 days) from day 2 every 4 weeks. In the absence of hematologic toxicity, TMZ was escalated to 1,000 mg/m(2) in 5 days. RESULTS: A total of 50 patients (median age, 53.4 years; range, 27 to 70 years; median Karnofsky performance status, 80; range, 60 to 100) were accrued in the study. PFS-6 was 34% (95% CI, 23% to 50%), and PFS-12 was 4% (95% CI, 0.3% to 16%). Median PFS was 18.4 weeks (95% CI, 13 to 25.9 weeks). Among 49 assessable patients, one complete response and nine partial responses were obtained, with an overall response rate of 20.4% (95% CI, 7.7% to 33%). Among 203 treatment cycles delivered, the most common grade 3 or grade 4 events included granulocytopenia in 7.9% of cycles, thrombocytopenia in 4%, and neurologic toxicity in three patients (6%). CONCLUSION: The new cisplatin plus bid TMZ regimen appears active in chemotherapy-naive patients with recurrent GBM and incurs an acceptable toxicity.     

A phase II trial of recombinant interferon alpha-2b and cisplatin in metastatic melanoma

In this phase II study 37 patients with metastatic melanoma were treated with cisplatin 100 mg/m2 every three weeks and interferon alpha-2b 10 MU subcutaneously three times weekly; 125 cycles were administered. Thirty-four patients were evaluable for response and all 37 patients were assessable for toxicity. Four patients stopped treatment with cisplatin because of severe nephrotoxicity, and six patients stopped therapy because of other toxicities. Response rate was 6/34 = 18% (95%) CI (confidence interval): 7%-35%). One patient reached complete response lasting 27+ months. Five patients obtained partial responses with a median duration of response of 7 months (range 5-15+ ). Median time to progression was 2.3 months (range 1-27+). Median survival was 5 months (range 1-27+). We conclude that the combination of high-dose cisplatin 100 mg/m2 and interferon alpha-2b is associated with unacceptable toxicity. Haematological toxicity and nephrotoxicity were pronounced and the response rate was meagre and not encouraging.     

Outpatient chemotherapy with gemcitabine and oxaliplatin in patients with biliary tract cancer

This phase II study was conducted to determine the efficacy and toxicity of a gemcitabine (GEM) and oxaliplatin (OX) chemotherapy protocol in patients with unresectable biliary tract cancer (BTC). Patients were treated with GEM 1000 mg m-2 (30 min infusion) on days 1, 8, 15, and OX 100 mg m-2 (2 h infusion) on days 1 and 15 (gemcitabine and oxaliplatin (GEMOX-3 protocol), repeated every 28 days. The data were collected according to the Simon 2-stage design for a single centre phase II study (alpha=0.05; beta=0.2). Primary end point was response rate; secondary end points were time-to-progression (TTP), median survival, and safety profile. Thirty-one patients were enrolled in the study between July 2002 and April 2005. Therapeutic responses were as follows: partial response in eight patients (26%, 95% confidence interval (CI) 14-44), stable disease in 14 patients (45%, 95%CI 29-62), resulting in a disease control rate of 71%. Nine patients (29%, 95%CI 16-47) had progressive disease. Median TTP was 6.5 months. Median overall survival was 11 months. Common Toxicity Criteria (CTC) Grade 3-4 toxicities were transient thrombocytopenia (23%), peripheral sensory neuropathy (19%), leucopenia (16%), and anaemia (10%). In conclusion the GEMOX-3 protocol is active and well tolerated in patients with advanced BTC. It can be applied in an outpatient setting with three visits per month only.     

Prospective randomized trial comparing mitomycin, cisplatin, and protracted venous-infusion fluorouracil (PVI 5-FU) With epirubicin, cisplatin, and PVI 5-FU in advanced esophagogastric cancer.

PURPOSE: We report the results of a prospectively randomized study that compared the combination of epirubicin, cisplatin, and protracted venous-infusion fluorouracil (PVI 5-FU) (ECF) with the combination of mitomycin, cisplatin, and PVI 5-FU (MCF) in previously untreated patients with advanced esophagogastric cancer. PATIENTS AND METHODS: Five hundred eighty patients with adenocarcinoma, squamous carcinoma, or undifferentiated carcinoma were randomized to receive either ECF (epirubicin 50 mg/m(2) every 3 weeks, cisplatin 60 mg/m(2) every 3 weeks and PVI 5-FU 200 mg/m(2)/d) or MCF (mitomycin 7 mg/m(2) every 6 weeks, cisplatin 60 mg/m(2) every 3 weeks, and PVI 5-FU 300 mg/m(2)/d) and analyzed for survival, response, toxicity, and quality of life (QOL). RESULTS: The overall response rate was 42.4% (95% confidence interval [CI], 37% to 48%) with ECF and 44.1% (95% CI, 38% to 50%) with MCF (P =.692). Toxicity was tolerable, and there were only two toxic deaths. ECF resulted in more grade 3/4 neutropenia and grade 2 alopecia, but MCF caused more thrombocytopenia and plantar-palmar erythema. Median survival was 9.4 months with ECF and 8.7 months with MCF (P =.315); at 1 year, 40.2% (95% CI, 34% to 46%) of ECF and 32.7% (95% CI, 27% to 38%) of MCF patients were alive. Median failure-free survival was 7 months with both regimens. Global QOL scores were better with ECF at 3 and 6 months. CONCLUSION: This study confirms response, survival, and QOL benefits of ECF observed in a previous randomized study. The equivalent efficacy of MCF was demonstrated, but QOL was superior with ECF. ECF remains one of the reference treatments for advanced esophagogastric cancer.     

Randomized trial of radiotherapy versus concurrent chemoradiotherapy followed by adjuvant chemotherapy in patients with American Joint Committee on Cancer/International Union against cancer stage III and IV nasopharyngeal cancer of the endemic variety.

PURPOSE: The Intergroup 00-99 Trial for nasopharyngeal cancer (NPC) showed a benefit of adding chemotherapy to radiotherapy. However, there were controversies regarding the applicability of the results to patients in endemic regions. This study aims to confirm the findings of the 00-99 Trial and its applicability to patients with endemic NPC. PATIENTS AND METHODS: Between September 1997 and May 2003, 221 patients were randomly assigned to receive radiotherapy (RT) alone (n = 110) or chemoradiotherapy (CRT; n = 111). Patients in both arms received 70 Gy in 7 weeks using standard RT portals and techniques. Patients on CRT received concurrent cisplatin (25 mg/m2 on days 1 to 4) on weeks 1, 4, and 7 of RT and adjuvant cisplatin (20 mg/m2 on days 1 to 4) and fluorouracil (1,000 mg/m2 on days 1 to 4) every 4 weeks (weeks 11, 15, and 19) for three cycles after completion of RT. All patients were analyzed by intent-to-treat analysis. The median follow-up time was 3.2 years. RESULTS: Distant metastasis occurred in 38 patients on RT alone and 18 patients on CRT. The difference in 2-year cumulative incidence was 17% (95% CI, 14% to 20%; P = .0029). The hazard ratio (HR) for disease-free survival was 0.57 (95% CI, 0.38 to 0.87; P = .0093). The 2- and 3-year overall survival (OS) rates were 78% and 85% and 65% and 80% for RT alone and CRT, respectively. The HR for OS was 0.51 (95% CI, 0.31 to 0.81; P = .0061). CONCLUSION: This report confirms the findings of the Intergroup 00-99 Trial and demonstrates its applicability to endemic NPC. This study also confirms that chemotherapy improves the distant metastasis control rate in NPC.     

Second-line chemotherapy with irinotecan and vinorelbine in stage IIIB and IV non-small-cell lung cancer: a phase II study

The purpose of this study was to evaluate the efficacy and tolerance of combined irinotecan and vinorelbine in previously treated patients with stage IIIB and IV non-small-cell lung cancer (NSCLC). Thirty-three patients with NSCLC (7 stage IIIB and 26 stage IV) were enrolled. All had been previously treated with cisplatin, paclitaxel, and gemcitabine as first-line chemotherapy. In addition, 24 patients had received radiotherapy. Irinotecan (300 mg/m(2)) was administered on day 1 and vinorelbine (30 mg/m(2)) on days 1 and 14, every 4 weeks. Partial response was achieved in 3 patients (9%; 95% CI: 2-24%), stable disease (SD) in 13 (39%; 95% CI: 23-58%), whereas 17 patients progressed (51%; 95% CI: 33-69%). Median event-free survival was 10 weeks and median overall survival was 25 weeks. Three patients were event free at the end of the study with a follow-up of 40, 73, and 75 weeks. Toxicity was mild, with leukopenia grade III-IV in 8.6% of cycles. No episodes of diarrhea III-IV were observed. Three patients died early after administration of this combination, one of them in the context of severe leukopenia and thrombocytopenia. Approximately 50% of patients treated with CPT-11 and vinorelbine in combination show partial response or stable disease with minimal toxicity.     

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 liposomal doxorubicin and gemcitabine in the salvage treatment of ovarian cancer

In total, 70 patients were enrolled into this phase II study, to evaluate the activity of the pegylated liposomal doxorubicin (PLD) and gemcitabine (GEM) combination in recurrent ovarian cancer patients. PLD, 30 mg m(-2), was administered on day 1 by 60' i.v. infusion, followed by GEM, 1000 mg m(-2), given by 30' i.v. on days 1 and 8; cycles were repeated every 21 days. In all, 67 patients are so far evaluable for response. Seven complete responses (10.4%, 95% CI: 3.1-17.7), 16 partial responses (23.9%, 95% CI: 13.7-34.1), 26 disease stabilisations (38.8%, 95% CI: 27.1-50.5) and 18 progressions (26.9%, 95% CI: 16.3-37.5) have been registered. Within the resistant population (n=36), the response rate was 25% (95% CI: 10.9-39.1). Within the group of platinum-sensitive patients (n=31), the response rate was 45.2% (95% CI: 27.7-62.7). A total of 443 courses are evaluable for toxicity. Grade 3-4 hematological toxicity was registered in 30 patients (42.8%), mainly represented by neutropenia (35.6%); palmar-plantar erythrodysesthesia affected 24 patients (34.2%), but it was of grade 3 in only seven of them (10%).     

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.
