RESUMO

The purpose of this multicentric Phase II study was to evaluate the safety and efficacy of a gemcitabine/oxaliplatin/vinorelbine combination as first-line therapy in advanced non-small cell lung cancer patients. Patients followed a fortnightly drug schedule, receiving on day 1, vinorelbine 25mg/m(2) (20-min infusion); gemcitabine 700 mg/m(2) (70-min infusion, fixed 10mg/m(2)/min); and on day 2, oxaliplatin 85 mg/m(2) (2-h infusion). Thirty-nine patients with a median age of 58 years received a total of 306 cycles (median 8 cycles); 67% were males. Most had adenocarcinoma (51%), large-cell (23%) and squamous cell carcinoma (21%); 15% had stage IIIB and 85% stage IV. There was one complete response (3%; 95% CI: 0.1-13%), 15 partial responses (PR) (38%; 95% CI: 23-55%), and 13 patients with stable disease (33%; 95% CI: 19-50%) of at least 2 months duration, for an overall non-progression rate of 74%. Median progression-free survival (PFS) was 4.1 months (95% CI: 3.1-8.7) and overall survival was 11.7 months (95% CI: 7.7-19.4). No treatment-related deaths occurred and very few grade 3-4 events were observed. Overall, the regimen was well tolerated and the planned recommended dose intensity was safely delivered to more than 95% of patients. This triple combination therapy study yielded favourable efficacy and toxicity results, which merit further evaluation in prospective randomised trials.

RESUMO

BACKGROUND: Phase I and pharmacokinetic study to determine the maximal tolerated dose and the recommended dose, as well as the optimal sequence of a carboplatin/oxaliplatin combination delivered every 3 weeks. PATIENTS AND METHODS: Patients received either carboplatin [area under the curve (AUC)-based individually calculated dose (starting dose AUC 4 mg.min/ml), 1 h intravenous (i.v.) infusion] followed by oxaliplatin (110 mg/m(2), 2 h i.v. infusion), every 3 weeks, or the reverse sequence. RESULTS: Sixteen patients were included and only one dose level was assessed. In group A, 10 patients received 23 cycles of carboplatin followed by oxaliplatin. In group B, 6 patients received 20 cycles with the reverse sequence. Delayed recovery from hematological toxicities was treatment-limiting, with mainly moderate thrombocytopenia and neutropenia as dose-limiting toxicities for group A (5 of 10 patients for each) and thrombocytopenia for group B (3 of 6 patients). No febrile neutropenia or grade 3/4 non-hematological toxicity occurred. Pharmacokinetic analysis showed similar mean total platinum AUCs for the two groups: 37.2 +/- 13.7 and 33.6 +/- 9.9 mg.h/l, respectively. One complete response and two partial responses (World Health Organization-International Union Against Cancer criteria, response rate 18.8%) were seen in ovarian, Fallopian and neuroendocrine carcinomas, respectively. CONCLUSIONS: This platinum combination appears feasible and active at the dose of AUC 4 mg.min/ml for carboplatin (Chatelut formula) and oxaliplatin 110 mg/m(2); however, it does not allow a significant increase in platinum dose-intensity delivery.

RESUMO

BACKGROUND: Oxaliplatin and vinorelbine are both active agents against non-small-cell lung cancer (NSCLC). In a previous phase I trial, we showed that oxaliplatin (130 mg/m2, day 1) and vinorelbine (26 mg/m2/day, days 1 and 8) can be safely combined when given every 21 days. We completed the evaluation of this new platinum-based doublet in advanced NSCLC patients in a multicenter phase II study. PATIENTS AND METHODS: Twenty-eight chemotherapy-naïve patients (22 men and six women: median age 58 years, range 33-70), including 20 with stage IV disease, received this out-patient combination, with 5-hydroxytryptamine-3-receptor agonists as the only prophylactic measure. RESULTS: A total of 117 cycles were given, for a median of three per patient (range 1-8). Of 26 eligible patients, nine achieved a partial response (WHO criteria), giving an objective response rate of 35% [95% confidence interval (CI) 17% to 56%]. The median progression free survival was 5.0 months (95% CI 3.1 to 6.9), median overall survival was 9.8 months (95% CI 2.2 to 17.5) and the 1-year survival rate was 37%. Neutropenia was the principal toxicity, grade 4 occurring in 11 patients (39%) and 25 cycles (22%). Four patients (14%) experienced one episode of febrile neutropenia each. Acute oxaliplatin-related neurosensory toxicity was prevalent, but was mild to moderate in the majority of patients (82%) and reversible. Grade 1/2 vomiting (65% of patients) and diarrhea (32% of patients) were easily managed. CONCLUSIONS: The oxaliplatin-vinorelbine doublet is a safe and active out-patient combination. It may represent an interesting alternative in the management of patients with NSCLC, and serve as a new doublet to which other active agents could be added.

RESUMO

PURPOSE: We conducted a retrospective analysis to evaluate the safety and efficacy of Campath-1H, an anti-CD52 humanized monoclonal antibody, in previously treated T-prolymphocytic leukemia (T-PLL) patients in a compassionate-use program. PATIENTS AND METHODS: Seventy-six patients with T-PLL (including four chemotherapy-naive patients) received 3, 10, and 30 mg of Campath-1H on sequential days, followed by 30 mg three times weekly, as 2-hour intravenous infusions, for 4 to 12 weeks. RESULTS: Median patient age was 60 years (range, 35 to 84). Spleen liver, lymph node, and skin involvement were present in 64%, 40%, 54%, and 18% of patients, respectively. All tested patients had CD2, CD7, CD4, and/or CD8 positivity, whereas CD5 and CD3 were positive in 98% and 96% of tested patients, respectively. The objective response rate was 51% (95% confidence interval [CI], 40% to 63%), with a 39.5% complete response (CR) rate (95% CI, 28% to 51%). The median duration of CR was 8.7 months (range, 0.13+ to 44.4), and median time to progression was 4.5 months (range, 0.1 to 45.4) compared with 2.3 months (range, 0.2 to 28.1) after first-line chemotherapy. The median overall survival was 7.5 months (14.8 months for CR patients). The most common Campath-1H-related adverse events were acute reactions during or immediately after infusions. Fifteen infectious episodes occurred during treatment in 10 patients (13%), leading to treatment discontinuation in three. Eight patients experienced possibly related, late-onset infections. Severe thrombocytopenia and/or neutropenia occurred in six patients (8%), leading to treatment discontinuation in four. Two treatment-related deaths occurred. CONCLUSION: Campath-1H is an active drug in T-PLL patients for whom first-line therapy has failed. It has a favorable risk/benefit ratio and should be prospectively investigated in chemotherapy-naive patients.

RESUMO

PURPOSE: To assess antitumor activity and safety of two regimens in advanced colorectal cancer (CRC) patients with proven fluorouracil (5-FU) resistance in a randomized phase II study: 5-FU/folinic acid (FA) combined with alternating irinotecan (also called CPT-11) and oxaliplatin (FC/FO tritherapy), and an oxaliplatin/irinotecan (OC) combination. PATIENTS AND METHODS: Sixty-two patients were treated: arm FC/FO (32 patients) received, every 4 weeks, FA 200 mg/m(2) followed by a 400-mg/m(2) 5-FU bolus injection, then a 600-mg/m(2) continuous infusion of 5-FU on days 1 and 2 every 2 weeks administered alternately with irinotecan (180 mg/m(2) on day 1) and oxaliplatin (85 mg/m(2) on day 15). Arm OC (30 patients) received oxaliplatin 85 mg/m(2) and irinotecan 200 mg/m(2) every 3 weeks. RESULTS: In an intent-to-treat analysis, two partial responses lasting 10.7 and 16 months were observed with the tritherapy regimen, and seven (median duration, 11 months; range, 10.6 to 11.4 months) were observed with the bitherapy regimen. Median progression-free and overall survival times were 8.2 and 9.8 months, respectively, in the FC/FO arm and 8.5 and 12.3 months, respectively, in the OC arm. Main grade 3/4 toxicities were, respectively, neutropenia, 53% and 47%; febrile neutropenia, 13% and 3%; diarrhea, 19% and 10%; vomiting, 6% and 13%; and neurosensory toxicity, 3% and 3%. No treatment-related deaths occurred. CONCLUSION: The every-3-weeks OC combination is safe and active in advanced 5-FU-resistant CRC patients. The lower activity data seen with the tritherapy regimen may be related to the lower dose intensities of irinotecan and oxaliplatin in this schedule.

RESUMO

PURPOSE: Oxaliplatin is a platinum compound active in non-small-cell lung cancer (NSCLC) patients, and vinorelbine (VNB) is an active reference agent. This phase I/II study was performed to determine the dose-limiting toxicity (DLT), the maximum-tolerated dose (MTD), and the recommended dose (RD) of a VNB/oxaliplatin combination given to previously untreated patients with advanced NSCLC. PATIENTS AND METHODS: Oxaliplatin was given at the fixed dose of 130 mg/m2 (2-hour intravenous [IV] infusion) on day 1. VNB was administered on days 1 and 8 (10-minute IV infusion), with doses starting at 22 mg/m2/d and escalated by 2 mg/m2 increments until MTD. Treatment was repeated every 3 weeks. No special hydration measures or prophylactic granulocyte colony-stimulating factors were used. RESULTS: Twenty-seven patients (20 men, 7 women) received 110 cycles total at six different VNB dose levels. Neutropenia was the DLT. Although no patient experienced DLT at the highest dose level (32 mg/m2/d), multiple treatment delays (54% of cycles) and dose reductions (34% of cycles) were required at this dose level. Others toxicities were mainly limited to grade 1 peripheral neuropathy and grade 1/2 nausea/vomiting. The relative dose-intensity of administered VNB from dose levels 3 to 6 (26 to 32 mg/m2) remained stable, whereas grade 3/4 neutropenia increased. All patients were assessable for activity; there were 10 objective responses, including one complete response (37% response rate). CONCLUSION: The present combination can be safely administered in an outpatient setting. The RD is VNB 26 mg/m2 days 1 and 8 with oxaliplatin 130 mg/m2 day 1 every 3 weeks.

RESUMO

Oxaliplatin (Eloxatin), a recently developed third-generation cisplatin analogue with a 1,2-diaminocyclohexane (DACH) carrier ligand, has displayed preclinical and clinical activity in a wide variety of tumour types. Synergistic with 5-FU in colorectal cancer (CRC), the combination has proven efficacy in 5-FU-resistant advanced disease and in previously untreated CRC, as demonstrated in controlled phase III trials, while evaluation in the adjuvant setting is ongoing. Due to its excellent safety profile, its unique mechanism of action and lack of cross-resistance with other active agents in CRC, oxaliplatin has also been combined with CPT-11 and Raltitrexed with promising results. Trials in pretreated and untreated advanced ovarian cancer (AOC), as a single agent or in combination with cisplatin, cyclophosphamide or paclitaxel, indicate a yet to be defined role in AOC and confirm its lack of cross-resistance with cis/carboplatin. Clinical investigations of single agent and combination therapies in breast, lung, prostate and germ-cell carcinomas, non-Hodgkin's lymphoma and malignant mesothelioma are being pursued. While the role of oxaliplatin in medical oncology is yet to be fully defined, it appears to be an important new anticancer agent.

RESUMO

PURPOSE: Only 20-30% of patient with advanced germ cell tumors, relapsing after standard first-line therapy, are curable with current second-line cisplatin-based regimens. New salvage combinations incorporating new active agents are needed. We report the toxicity/tolerance of a new salvage regimen based on the oxaliplatin (Eloxatin)/cisplatin combination, evaluated in patients with recurrent, mostly cisplatin-refractory germ cell tumors. PATIENTS AND METHODS: Thirteen patients were enrolled in this study. All except one had received cisplatin-based chemotherapy. Eight had progressive disease as the best response on their last platinum-based chemotherapy, and three had potentially sensitive tumors. The median interval since the last platinum-based chemotherapy was 6 months (range: 1-36 months). One untreated patient with poor prognosis was also enrolled. Twelve patients had pathological markers [median alpha-fetoprotein 14 800 ng/ml (58-10(6)), median human chorionic gonadotrophin beta subunit 7000 IU/ml (37-723 700)]. Patients received either oxaliplatin (130 mg/m(2)) and cisplatin (100 mg/m(2)) every 3-4 weeks (Bi regimen, four patients), or the same regimen combined with one to four of the following cytotoxic agents: ifosfamide, epirubicin, vinorelbine, methotrexate, dactinomycin, etoposide and bleomycin (BiC regimen, 9 patients). Treatment was individualized according to each individual patient's pretreatment and clinical characteristics. RESULTS: Seven objective responses were obtained (overall response rate = 54%), all with the BiC regimens (two complete and five partial responses). Two patients with recurrent disease achieved a long-term complete response lasting over 5 years. Four partial responders were seen in the eight cisplatin-refractory tumors, lasting 4-8 months. All objective responses had a corroborating major decrease in tumor marker blood levels (median decrease: 99.7%). The median survival for the whole group was 8 months. The commonest severe toxicity was hematological (grade 4 neutropenia in 78% and thrombopenia in 74% of the BiC cycles). CONCLUSION: Our combined salvage regimen induced significant antitumoral activity in recurrent, cisplatin-refractory germ cell tumors. Oxaliplatin merits further evaluation as a component of combination therapy for this disease.

RESUMO

Oxaliplatin (Eloxatin; Sanofi, Gentilly, France), a third-generation platinum compound with a 1,2-diaminocyclohexane (DACH) carrier ligand, is a recently developed agent with activity in colorectal cancer (CRC). Preclinical and clinical observations demonstrate synergistic effects with 5-fluorouracil (5-FU), even in 5-FU-resistant tumors. The supradditive pharmacodynamics of the combination have also been proven in previously untreated CRC patients in controlled phase III trials. Due to its excellent safety profile, unique mechanism of action, and lack of cross-resistance with other CRC chemotherapeutic agents, oxaliplatin can be combined with 5-FU, irinotecan (CPT-II), raltitrexed, or other agents. Future directions of development are to determine the optimal administration scheme and the most effective combinations of oxaliplatin with 5-FU or with other anticancer agents. Ongoing controlled studies in adjuvant therapy will further define the place of oxaliplatin in the treatment of CRC.

RESUMO

The introduction of oxaliplatin into the colorectal cancer setting represents a significant advancement in the treatment of the disease. Synergistic effects with traditional therapy 5-fluorouracil/folinic acid have increased response rates significantly, improved time-sensitive response parameters, and facilitated the removal of previously unresectable hepatic metastases, thus changing the natural history of the disease. Ongoing and planned trials are identifying various issues that need to be addressed to fully realize the potential of oxaliplatin. These include optimization of dosing and schedule of administration, determination of the most effective oxaliplatin-5-fluorouracil/folinic acid combination, definition of the role of new thymidylate synthase inhibitors with respect to oxaliplatin therapy, and identification of the most effective combinations of oxaliplatin with the new anticancer agents that have been recently introduced. Providing the answers to these questions will contribute to changing the attitude of the clinical oncologist regarding what strategy to adopt in treating colorectal cancer in the coming years.

RESUMO

BACKGROUND: Patients presenting with brain metastases from renal cell carcinoma portend a poor prognosis, with a reported median survival of 4-6 months. Given their short life expectancy, these patients generally have been excluded from clinical trials that assess the efficacy of medical treatments. However, clinical impression suggests that some patients may achieve long term palliation. METHODS: The clinical features of 68 patients who were treated at the Institut Gustave Roussy for brain metastases from renal cell carcinoma were collected retrospectively. Using univariate and multivariate analyses, a prognostic model based on independent prognostic factors was established. An external data set of 57 patients was used to validate the model. RESULTS: The median survival was 7 months. On univariate analysis survival was related significantly to the following adverse prognostic factors: no initial nephrectomy, left side and temporal location of brain metastases, presence of fever or weight loss, erythrocyte sedimentation rate > 50 mm/h, and time from initial diagnosis to brain metastases < or = 18 months. Multivariate analyses identified the previous variable as well as the presence of other visceral metastases as independent prognostic factors. Forty-four patients (65%) with no or 1 adverse prognostic factor (average risk group) had a median survival of 8 months and a 26% 1-year survival rate. Twenty-four patients (35%) with 2 adverse prognostic factors (poor risk group) had a median survival of 3 months and a 1-year survival rate of 9%. This model proved to be discriminant in an external data set; the median survival of patients assigned to the average risk group was 11 months (46% 1-year survival rate) compared with 4 months (9% 1-year survival rate) for patients assigned to the poor risk group. CONCLUSIONS: Patients presenting with brain metastases from renal cell carcinoma and poor risk prognostic factors are highly unlikely to benefit from medical treatments except symptomatic procedures. Conversely, the enrollment of patients with average risk prognostic factors into clinical trials dealing with chemotherapy or immunotherapy may be considered.

RESUMO

Forty poor-risk patients with metastatic nonseminomatous germ cell tumors were treated with a chemotherapy regimen that consisted of either the BEP protocol (bleomycin + etoposide + cisplatin) or the CISCA(II)/VB(IV) regimen (cyclophosphamide + doxorubicin + cisplatin/vinblastine + bleomycin). There was no randomization. Among 17 patients who received the CISCA(II)/VB(IV) protocol, three early deaths, four primary failures, and 10 complete responses were observed. Two relapses and one acute myeloid leukemia were subsequently noted. Nine (53%) of 17 patients remain free of disease 15-38 months after the end of therapy. In the group of patients treated with the BEP regimen, one early death, one primary failure, one toxic death, one partial response, and 19 complete responses were observed. There were eight relapses. Sixteen (70%) of 23 patients remain free of disease 26-52 months after the end of therapy. Myelosuppression and mucositis were clearly more severe with the CISCA(II)/VB(IV) regimen. However, no septic death was registered, whereas one patient died of septic shock after the fourth cycle of BEP. Investigators of the Genitourinary Group of the French Federation of Cancer Centers have now embarked on a prospective randomized trial of BEP versus CISCA(II)/VB(IV) in poor-risk patients.

RESUMO

BACKGROUND: Approximately 30% of patients with metastatic germ cell tumors require salvage chemotherapy for recurrent or refractory disease after first-line treatment. The optimal salvage chemotherapy regimen remains to be determined. METHODS: Fifty-four patients with metastatic germ cell tumors who failed to be cured with first-line therapy, were treated with a salvage VIP/VeIP regimen including cisplatin (20 mg/m2/d dl to d5), ifosfamide (1.2 gm/m2/d dl to d5), and either etoposide (75 mg/m2/d dl to d5) or vinblastine (0.11 mg/kg/d dl and d2) for 5 consecutive days every 3 weeks. RESULTS: A complete remission was observed in 24 patients (44%) at completion of VIP/VeIP chemotherapy. In 17 patients (31%), complete remission was reached with chemotherapy alone, whereas four (7%) were rendered tumor-free by resection of the residual inactive tumor. Three patients (6%) became tumor-free by resection of the residual carcinoma. Ten other patients (19%) achieved a partial response, with normalization of serum tumor markers. Eleven of those thirty-four patients additionally received high-dose chemotherapy with hematopoietic stem cell support as consolidation treatment. Twenty patients (37%) were judged to be treatment failures because of either incomplete response (3 patients) or progression of disease (17). Myelotoxicity was severe, but no toxicity deaths were noted. After a median follow-up of 30 months, 23 patients (43%) are alive, 16 of whom (30%) are without evidence of progression of disease. Among patients who received high-dose chemotherapy, the relapse-free survival was 63% compared with 35% for patients who did not receive this consolidation treatment. CONCLUSIONS: Currently available salvage chemotherapy with ifosfamide and cisplatin is predicted to cure approximately 30% of the patients who have failed first-line treatment. Whether high-dose chemotherapy with hematopoietic stem cell support after salvage VIP/VeIP could improve these modest results remains to be confirmed in a randomized study.

RESUMO

In order to assess the results of cisplatin-based chemotherapy after primary lymph node dissection in patients with pathological stage II nonseminomatous germ cell tumors of the testis, we retrospectively reviewed the long-term outcome of 44 patients who received adjuvant chemotherapy at Institut Gustave Roussy over a 7-year period. Two chemotherapy regimens were sequentially delivered. Twenty-three patients were treated with vinblastine, cyclophosphamide, bleomycin, actinomycin D, and cisplatin (mVAB-6, four cycles), while 21 patients received a combination of etoposide and cisplatin (EP, four cycles). After a median follow-up of 6 years, all patients remain free from progression. The long-term toxicity included retrograde ejaculation in eight patients and severe ototoxicity in two patients. We conclude that four cycles of cisplatin-based chemotherapy for pathological stage II testicular cancer resulted in a 100% cure rate with minimal toxicity.

RESUMO

The sarcomatoid variant of renal cell carcinoma is a clinical entity with local and metastatic aggressiveness which translates to short survival time. Fourteen cases of patients that fit strict criteria for sarcomatoid cell carcinoma and convenient clinical data for treatment and follow-up were retrospectively selected among 1,235 patients treated at the Institut Gustave-Roussy over a 17-year period. Thirteen patients underwent initial nephrectomy. Local recurrence or distant metastases occurred in all patients. Only 1 patient was treated by surgical removal of a unique lung metastasis and is currently alive with no evidence of disease. No response was observed in all 4 patients treated with alpha-interferon. Chemotherapy was administered in 10 patients, 8 of whom received doxorubicin-based regimens. The survival was 20, 29 and 60 months for the 3 responding patients as compared to a median of 9 months for patients with progressive disease. Further phase II studies are warranted to define the real impact of chemotherapy in this disease.

RESUMO

We evaluated the efficacy and safety of a monotherapy by piperacillin and sulbactam potentially associated to vancomycin as an empiric antimicrobial therapy in febrile neutropenic patients treated with nephrotoxic chemotherapy for solid tumors. Twenty-three patients were treated during 32 episodes with piperacillin 4 g i.v. every 8 hours and sulbactam 1 g IV every 8 hours. If the patient remained febrile after 48 hours, 1 g of vancomycin i.v. was added every 12 hours as indicated by our study design. The mean duration of neutropenia was 5.5 days (2-13 days). In ten episodes, the granulocyte nadir was < 100/mm3. Infection was microbiologically documented in seven episodes (22%) with six Gram negative bacilli and 3 Gram positive cocci. There were 19 apyrexia with piperacillin and sulbactam (59%) and further seven were resolved by the addition of vancomycin (total success: 81%). Failure was observed in six episodes consecutive to germ resistance (one episode), clinical deterioration (one episode), relapsing fever related to Pseudomonas infection (one episode), persistent fever despite withdrawal of neutropenia and no microbiological documentation (two episodes) and protocol violation (one episode). Neither septic death nor toxicity were observed. We conclude that this empirical treatment is active and safe in short period febrile neutropenic episodes in patients heavily treated with nephrotoxic chemotherapy for solid tumors.

RESUMO

We report a case of spermatic cord liposarcoma in a 72-year-old man. Local disease progression was observed in spite of multinodal treatment, including repeated wide surgical excision, radiotherapy and chemotherapy. The literature and the treatment modalities of spermatic cord liposarcomas are reviewed.
