PREMIUM: A French prospective multicenter observational study of factors impacting on efficacy and compliance to cetuximab treatment in first-line KRAS wild-type metastatic colorectal cancer. PLoS One 2020; 15:e0243997. [PMID: 33347495 PMCID: PMC7752147 DOI: 10.1371/journal.pone.0243997] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Accepted: 12/01/2020] [Indexed: 11/18/2022] Open
Abstract
Background Cetuximab improves progression-free survival (PFS) and overall survival (OS) in patients with KRAS wild type (wt) metastatic colorectal cancer (mCRC). Few data are available on factors impacting both efficacy and compliance to cetuximab treatment, which is, in combination with chemotherapy, a standard-of-care first-line treatment regimen for patients with KRAS wt mCRC. Patients and methods PREMIUM is a prospective, French multicenter, observational study that recruited patients with KRAS wt mCRC scheduled to receive cetuximab, with or without first-line chemotherapy, as part of routine clinical practice, between October 28, 2009 and April 5, 2012 (ClinicalTrials.gov Identifier: NCT01756625). The main endpoints were the factors impacting on efficacy and compliance to cetuximab treatment. Predefined efficacy endpoints were PFS and safety. Results A total of 493 patients were recruited by 94 physicians. Median follow-up was 12.9 months. Median progression-free survival was 11 months [9.6–12]. In univariate analyses, ECOG performance status (PS), smoking status, primary tumor location, number of metastatic organs, metastasis resectability, surgery, folliculitis, xerosis and paronychia maximum grade, and acne preventive treatment were statistically significant. In multivariate analysis (Hazard Ratios of multivariate stepwise Cox models), ECOG PS, surgery, xerosis and folliculitis were positive prognostics factors for longer PFS. Among all patients, 69 (14%) were non-compliant. In multivariate analysis, no variables were statistically significant. The safety profile of cetuximab was consistent with previous studies. Conclusions ECOG PS <2, surgical treatment performed, and maximum grade xerosis or folliculitis developed were predictive factors of cetuximab efficacy on KRAS wt mCRC patients. Unfortunately, we failed in identifying predictive factors for compliance in these patients.

Abstract
BACKGROUND The purpose of this study was to describe the fracture incidence and bone mineral density (BMD) evolution in a large cohort of post-menopausal women with breast cancer after 3 years of aromatase inhibitor (AI) therapy. PATIENTS AND METHODS A prospective, longitudinal study in real-life setting. Each woman had an extensive medical assessment, a biological evaluation, a BMD measurement, and systematic spinal X-rays at baseline and after 3 years of AI therapy. Women with osteoporosis at baseline (T-score < -2.5 and/or non-traumatic fracture history) were treated by oral weekly bisphosphonates. RESULTS Among 497 women (mean age 63.8 ± 9.6 years) included in this study, 389 had a bone evaluation both at baseline and after 3 years of AI therapy: 267 women (mean age 61.2 ± 8.6) with no osteoporosis at baseline and 122 women (mean age 67.2 ± 9.1) with osteoporosis at baseline justifying a weekly oral bisphosphonate treatment. Women without bisphosphonates had a significant decrease in spine BMD (-3.5%, P < 0.01), neck BMD (-2.0%, P < 0.01), and total hip BMD (-2.1%, P < 0.01) over the 3 years but only 15 of them (5.6%) presented an incident vertebral or non-vertebral fracture. In osteoporotic women treated with bisphosphonates, spine and hip BMD were maintained at 3 years but 12 of them (9.8%) had an incident fracture. These fractured women were significantly older (74.1 ± 9.8 versus 66.5 ± 8.8) but also presented BMD loss during treatment suggesting poor adherence to bisphosphonate treatment. CONCLUSION This real-life study confirmed that AIs induced moderate bone loss and low fracture incidence in post-menopausal women without initial osteoporosis. In women with baseline osteoporosis and AI therapy, oral bisphosphonates maintain BMD but were associated with a persistent fracture risk, particularly in older women.

Abstract
BACKGROUND The purpose of this study was to describe bone status in a large cohort of postmenopausal women with nonmetastatic breast cancer, at the initiation of aromatase inhibitor therapy. PATIENTS AND METHODS A prospective, transversal and clinical study was conducted. Each woman had an extensive medical history, a biological evaluation, a bone mineral density (BMD) measurement and spinal X-rays. RESULTS Four hundred and ninety-seven women aged 63.8 ± 9.6 years were included in this study. Eighty-five percent of these women had a 25-OH vitamin D concentration <75 nmol/l. One hundred and fifty-six women (31.4%) had a T-score < -2 at one of the three site measurements. Ninety-five women (19.1%) had a history of nonvertebral fracture with a total of 120 fractures. Spine X-rays evaluation revealed that 20% of the women had at least one vertebral fracture. The presence of vertebral fracture was associated with nonvertebral fracture history [odds ratio (OR) 1.6, 95% confidence interval (CI) 1.1-2.4] and with spine BMD (OR 1.4, 95% CI 1.1-1.7). The prevalence of vertebral fracture reached 62.9% in women with age above 70 years and femoral T-score < -2.5. CONCLUSION Before starting aromatase inhibitor therapy for breast cancer, a large proportion of women had a vitamin D insufficiency and vertebral fractures.

Abstract
12029 Background: Optimizing drug delivery based on pharmacokinetic data is an important research issue. Previous studies have demonstrated a pharmacological advantage for infusions of G with a fixed dose rate to maximize cellular accumulation of G active metabolite (GTP), despite high interindividual PK variability. Methods: To develop a PK-guided G dosing schedule, we conducted an intra-pt G DE trial to determine: (1) maximum tolerated dose level (MTD) and dose-limiting toxicity (DLT), (2) plasma G and peripheral mononuclear cell GTP post-infusion levels. G was administered over 150 min on day 1, 8 and 15, q4w. The initial dose level (DL) was 1000 mg/m2, escalated by 250 mg/m2 every cycle (cy) if no limiting toxicity occurred. Results: From 09/2003, 30 pts entered the study. Pts’ characteristics: 16 men/14 women; median age 66 years (49–81); tumor type: pancreas (10 pts), lung (7 pts), others (13 pts); prior chemotherapy (15 pts). A total of 109 cy were given (median: 3 cy/pt). Tolerance: Number of pts/DL: DL1 = 7 pts, DL2 = 5 pts, DL3 = 11 pts, DL4 = 5 pts, DL5 = 2 pts. Main reasons for stopping DE were: disease progression/early death (15 pts), DLT (4 pts), investigator’s decision (8 pts). DLT were: haematological (1 pt), asthenia (2 pts) and infection (1 pt). Most common grade (gr) 1–2/3–4 toxicities (% cy) included: nausea/vomiting (38%/2%), asthenia (56%/11%), neutropenia (29%/27%) and thrombocytopenia (42%/1%). Activity: 26 pts are evaluable (radiological assessment every 3 cycles) showing 5 partial response (2 unconfirmed), 7 stabilization and 14 progression. Conclusions: The main reason for DE failure was early progression, stressing the importance of an early individual dose adjustment. PK and PK/PD correlation analyses are ongoing to confirm our hypothesis. No significant financial relationships to disclose.

Abstract
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.

Abstract
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.

Abstract
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.

Combination raltitrexed (Tomudex(R))-oxaliplatin: a step forward in the struggle against mesothelioma?

Abstract
The aim of this study was to review the experience of the Institut Gustave Roussy in 163 patients with malignant mesothelioma over a 9-year period. Data from seven consecutive prospective trials, four of chemo-immunotherapy and three of chemotherapy were reviewed. The rationale, methods and results of these trials are summarised and discussed. 98 patients were included in four phase II trials of chemo-immunotherapy whose common denominator was a combination of cisplatin and alpha-interferon. The response rate ranged from 15% to 40%. High-dose weekly cisplatin combined with alpha-interferon yielded the highest response rate but the toxicity of this regimen was considered unacceptable. Neither higher doses of alpha-interferon or the addition of mitomycin C or interleukin-2 to the regimen were able to enhance the activity of this combination. 18 patients were included in a paclitaxel-cisplatin phase II trial. The response rate was only 6% (95% confidence interval (CI): 0-24) and toxicity was also significant. This regimen was, therefore, considered ineffective. Of 17 patients with mesothelioma included in a phase I trial that combined raltitrexed and oxaliplatin, 6 (35%) obtained a partial response. Responses were seen even in cisplatin-refractory mesothelioma. Preliminary results of a subsequent ongoing phase II trial using raltitrexed (3 mg/m(2)) and oxaliplatin (130 mg/m(2)) have confirmed this promising activity with a 30% (9/30) response rate (95% CI: 15-49). The tolerance of this outpatient regimen is acceptable (no significant haematological toxicity and no alopecia) and compares favourably with that of our previous regimens. The final results concerning response and survival are required to confirm the efficacy of this combination. The preliminary results of two studies suggest promising activity with the combination of raltitrexed-oxaliplatin in malignant mesothelioma. The efficacy/toxicity ratio of this combination compares favourably with that of our previous chemotherapy and chemo-immunotherapy regimens.

Sensitivity to CPT-11 of xenografted human colorectal cancers as a function of microsatellite instability and p53 status. Br J Cancer 2000; 82:913-23.

Abstract
Biological parameters influencing the response of human colorectal cancers (CRCs) to CPT-11, a topoisomerase 1 (top1) inhibitor, were investigated using a panel of nine CRCs xenografted into nude mice. CRC xenografts differed in their p53 status (wt or muf) and in their microsatellite instability phenotype (MSI+ when altered). Five CRC xenografts were established from clinical samples. All five had a functional p53, two were MSI+ and three were MSI-. Tumour-bearing nude mice were treated intraperitonealy (i.p.) with CPT-11. At 10 mg kg(-1) of CPT-11, four injections at 4-day intervals, four of the five xenografts responded to CPT-11 (growth delay of up to 10 days); the non-responder tumour was MSI-. At 40 mg kg(-1) of CPT-11, six injections at 4-day intervals, the five CRCs displayed variable but marked responses with complete regressions. In order to assess the role of p53 status in CPT-11 response, four CRC lines were used. HT29 cell line was MSI-/Ala273-mutp53, its subclone HT29A3 being transfected by wtp53. LoVo cell line was MSI+/wtp53, its subclone X17LoVo dominantly expressed Ala273-mutp53 after transfection. LoVo tumours (MSI+/mutp53) were more sensitive than X17LoVo (MSI+/mutp53. HT 29 tumours (MSI-Imutp53), were refractory to CPT-11 while HT29A3 tumours (MSI-/wtp53) were sensitive, showing that wtp53 improves the drug-response in these MSI- tumours. Levels of mRNA expression of top1, fasR, TP53 and mdr1 were semi-quantified by reverse transcription polymerase chain reaction. None of these parameters correlated with CPT-11 response. Taken together, these observations indicate that MSI and p53 alterations could be associated with different CPT-11 sensitivities; MSI phenotype moderately influences the CPT-11 sensitivity, MSI+ being more sensitive than MSI(-)CRC freshly obtained from patients, mutp53 status being associated with a poor response to CPT-11.

Abstract
Gene amplification is one of the characteristics of cancer cells. In vitro studies suggested that alterations of the TP53 gene might be responsible for gene amplification. We have examined the presence of TP53 mutations and looked for cytogenetic evidence of gene amplification in a series of 79 primary colorectal carcinomas. Other parameters such as the pattern of cytogenetic alterations, microsatellite instability, tumor site, and histological staging were also considered. A multiparametric study supported by statistical analyses suggests the existence of two major pathways of colorectal carcinogenesis. No relationships could be established between the presence of TP53 alterations and gene amplification.

Abstract
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.

Abstract
PURPOSE To provide evidence for the therapeutic efficacy of oxaliplatin (Eloxatin) when given as a 2-6-hour i.v. infusion, alone or in combination with 5-fluorouracil/folinic acid (5-FU +/- FA) in patients with advanced colorectal carcinoma (ACRC) who have failed 5-FU-based therapy. To confirm the safety of the drug and its combination in an extended-access context. PATIENTS AND METHODS Prescribing physicians were supplied oxaliplatin on a nominative compassionate-use basis, after obtaining informed consent. Europe-wide, 206 ACRC patients in 44 centers received 1168 cycles of chemotherapy with oxaliplatin (80-100 mg/m2 q 2 weeks or 100-135 mg/m2 q 3 weeks) delivered as a short (2-6 hours) i.v. infusion, 177 of them (1026 cycles) receiving oxaliplatin + 5-FU +/- FA. RESULTS Oxaliplatin added to the 5-FU +/- FA regimens of 111 verified 5-FU-refractory patients (imaging and/or clinical proof of progression under prior 5-FU-based regimen), elicited objective responses in 25 of 98 evaluable patients, (ORR: 25.5%, 95% confidence interval (95% CI: 17-35). The median time to progression was 4.1 months (95% CI: 3.3-5.0) and the median overall survival was 9.6 months (95% CI: 8.2-10.9). Differences in the toxicity profile of the oxaliplatin + 5-FU +/- FA combination appear related to administration modality, dose and schedule of the 5-FU-based regimen. CONCLUSIONS The addition of oxaliplatin (2-6-hour i.v. infusion) to 5-FU +/- FA regimens is active in ACRC patients with clinical resistance to fluoropyrimidines. The therapeutic index of oxaliplatin + 5-FU +/- FA combinations administered as salvage therapy compares favorably with those reported in recent phase II-III trials involving other new agents or combinations active in 5-FU-refractory ACRC patients.

Abstract
BACKGROUND Many patients with advanced NHL ultimately relapse and require salvage treatment. Oxaliplatin, a diaminocyclohexane (DACH) platinum, has shown a differential spectrum of cytotoxicity with cisplatin, with activity in primary or secondary cisplatin-resistant solid tumors (colon and ovarian cancer). We report the tolerance/activity of this platinum derivate in previously-treated NHL patients. PATIENTS AND METHODS From July 1988 to February 1994, 22 patients (11 men, 11 women) with recurrent NHL received single-agent oxaliplatin (100-130 mg/m2 i.v. over two hours with antiemetic premedication, q three weeks). All had been previously treated (median number of prior chemotherapy regimens 2, range 1-7) > or = 1 alkylating agent: 22 patients, anthracyclines: 18 patients, cisplatin: four patients, and radiation: 11 patients. Fourteen patients (63%) had progressive disease as best response to their last chemotherapy, and were considered treatment-refractory. All histologies were centrally reviewed in accord with the R.E.A.L. Classification; they were: eight follicular, five MCL, three diffuse large cell, two MALT, one lymphoplasmocytoid, and three other. RESULTS A total of 144 cycles were administered for a median number of 6 (range 1-30) per patient. The objective response rate was 40% (95%, CI: 21-64), including one CR (MCL) and eight PRs (four follicular, two MCL, two MALT). The median response duration was 27 months (range 5-44). Treatment-related toxicity was limited to grade 1-2 nausea/vomiting and reversible grade 1-2 peripheral neuropathy in most of the patients. CONCLUSION Oxaliplatin is an active agent in relapsed/refractory NHL, including the MCL type. Its safety profile makes this agent a good candidate for the development of combined salvage regimens. Further phase II studies are needed to confirm these preliminary results.

Abstract
The aim of this phase II study was to determine the antitumour activity and safety of trans-1-diaminocyclohexane-platinum (oxaliplatin) in previously untreated advanced non-small cell lung cancer (NSCLC) patients. 33 patients with unresectable and measurable NSCLC were entered into this phase II study between January 1992 and January 1994. Patients had either locoregional disease with performance status 2 (19 patients) or a stage IV disease (14 patients). Oxaliplatin (130 mg/m2) was given on an out-patient basis (2-h infusion, every 21 days) without hydration. Response was assessed after every two courses. One hundred courses were administered, with a mean of three courses per patient (range 1-12). All patients were evaluable for response; 1 had a complete response, and 4 a partial response (overall response rate 15%, 95% confidence interval 5.1-31.9%). The median response duration was 5.9 months. All cycles (n = 100) were evaluable for toxicity assessment. Transient reversible, cold-related finger dysesthesias occurred in 29 patients, but were mild, and disappeared in most cases within a few days. We observed brief episodes of pharyngolaryngeal discomfort (8 patients, 11 episodes) accompanied in 4 cases (3 patients), by transient episodes of inspiratory stridor, leading 2 patients to treatment withdrawal. We conclude that oxaliplatin has activity in poor-prognosis NSCLC and that this treatment is feasible in out-patients; the absence of renal and haematological toxicity makes this drug a good candidate for further evaluation in NSCLC.

Abstract
Management of advanced malignant mesothelioma (MM) still requires innovative systemic therapy as its prognosis is poorly affected by currently available chemotherapy. The combination cisplatin and alpha-interferon (alpha-INF) has synergistic antitumoral activity in preclinical models and interesting activity in phase I-II clinical trials. Weekly CDDP (60 mg/m2) and alpha-IFN (3 MUI/d: d1-d4) in combination was tested in a previous phase I-II study in 23 MM patients, with a 36% objective response rate (ORR). A trial with higher doses of alpha-IFN in the same combination schedule was conducted to explore an incrementalist hypothesis. Thirty patients with MM received the same CDDP dose (60 mg/m2/w) and doubled doses of alpha-IFN (6 MUI/d: d1-d4). The treatment protocol consisted of two cycles of 4 weeks on/4 weeks off followed by two shorter cycles of 3 weeks on/3 weeks off, in the absence of life-threatening toxicity or progressive disease. All patients were evaluable for toxicity. The main treatment-limiting side-effects were digestive intolerance (nausea, vomiting) and severe asthenia. Antitumoral efficacy was not increased (ORR = 27%). Haematological and neurological toxicities were moderate and manageable. The antitumoral activity of the CDDP-alpha-IFN combination with higher doses of the latter is similar to our previous experience, but tolerance issues make it a poorer choice for eventual comparative trials, or as a standard therapeutic indication.

Abstract
Our objective was to determine the maximum tolerated dose (MTD) of paclitaxel when given as a 7 day continuous i.v. infusion, repeated every 3 weeks, and to evaluate the toxicity and the efficacy of such a schedule of administration as a salvage treatment in ovarian cancer patients pretreated and refractory to 3 or 24 h paclitaxel. Thirteen women were enrolled in this phase I trial. Four dose levels ranging from 105 to 157.5 mg/m2/cycle were explored. Two of four patients experienced dose-limiting febrile neutropenia at the dose of 157.5 mg/m2. No objective response was observed, although three patients experienced disease stabilization (five to six cycles), with regression of disease symptoms, two of them having sustained 50% or greater decrease in CA 125. We conclude that the MTD in this population was paclitaxel 140 mg/m2/7 days. Schedule-dependent mechanisms of resistance to paclitaxel could not be demonstrated in this clinical setting of heavily pretreated ovarian cancer patients.

Abstract
We report the first case of junctional tachycardia in a patient treated with paclitaxel. A 60-year-old woman with advanced breast cancer received palliative chemotherapy with 22.5 mg/m2/day paclitaxel over a 7 day continuous infusion as part of an investigational regimen. Although the patient had no previous or current history of cardiac disease, she developed severe symptomatic tachycardia, which occurred toward the end of the second and third courses. Anti-arrhythmic medication was prescribed and electrocardiographic records identified electric patterns of junctional tachycardia. Given both the physiopathology of arrhythmic disorders and pharmacokinetics of the patient, this case report supports the hypothesis that automatic junctional rhythm after severe asymptomatic conduction block rather than direct primary toxicity on myocytes caused this toxicity.

Abstract
The aim of this study was to evaluate the toxicity and the activity of two non-cross-resistant platinum compounds: oxaliplatin (L-OHP) and cisplatin (CDDP) in platinum pretreated ovarian cancer patients. Chemotherapy consisted of L-OHP and CDDP given sequentially as 2 h infusions on day 1 at their standard recommended dose (130 mg/m2 for oxaliplatin, 100 mg/m2 for cisplatin) every 3 weeks. Dose reductions (20-35%) were planned according to baseline haematological and renal status, but the dose ratio between L-OHP and CDDP was always maintained at 1.3. Cycles were repeated until progression or treatment limiting toxicities. From September 1992 to November 1994, 25 patients with pretreated ovarian cancer entered this salvage programme. They had received a median number of three previous chemotherapy lines (1-7), one at least platinum based. Previously cisplatin had been given to 22 patients at a median total dose of 600 mg/m2 (170-1175), while 18 had received carboplatin to a median total dose of 1135 mg/m2 (200-2450). 9 patients had also received and were resistant to taxanes (paclitaxel, 6 patients, docetaxel, 3 patients), while the rest were considered ineligible for simultaneously ongoing single-agent taxane phase II trials. 13 and 12 patients, respectively, were considered to have platinum refractory and potentially sensitive disease, according to Markman's criteria. 77 cycles of L-OHP/CDDP were given, with a median of three cycles/patient (range 1-6) and were evaluable for toxicity. The limiting toxicity of the L-OHP/CDDP combination was a cumulative, sensory peripheral neuropathy, severe (> or = grade 3 CTC) after more than three cycles, but reversible within a few months of its discontinuation. Grade 3-4 (WHO scale) neutropenia and thrombopenia were seen in 35-40% of cycles, with one neutropenic treatment-related death (septic shock). 22 patients with measurable/evaluable disease were assessable for antitumoral activity. Two complete responses (CR) (8%) (one proven histologically at laparotomy (pCR)) and 8 partial responses (PR) (32%) for an overall objective response rate (ORR) of 40% (95% CI, 21-61%) (intent to treat). The median duration of response was 4 months. Seven responses were seen among 12 potentially platinum-sensitive tumours (58%, CI 95% 28-85%), while 3/13 platinum refractory patients (23%, CI 95% 5-54%) had an objective response. These encouraging results are the basis for new first- and second-line combination treatment programmes in ovarian carcinoma.

Abstract
Oxaliplatin is a new platinum analog of the DACH family. Recent preclinical data have confirmed its non overlapping spectrum of activity with cisplatin, including acquired and intrinsic platinum resistant cell lines (as KB-CP, A 2780, HT29, CaCo2 colon cancer). When combined with other cytotoxic agents (5FU, SN38, CDDP, carboplatin), oxaliplatin has additive and/or synergistic antitumoral effects on various in vitro and in vivo models (colon, breast, ovarian and epidermoid tumors). Phase II trials have confirmed a sensorial peripherical neuropathy as its limiting toxicity while neither ototoxicity nor renal toxicities and only limited myelotoxicity were noted. Available phase II studies have established its antitumoral activity as single agent in 5FU refractory colon carcinoma while preliminary results suggest efficacy in cisplatin resistant ovarian cancer, in non small cell lung cancer, non Hodgkin lymphoma. Antitumoral activity has been observed during phases 1 in melanoma, glioma, breast and oesophageal cancers. A high response rate (28-65%) with the triple association (FU/folinic acid/oxaliplatin) has been reported in advanced colon cancer treated in first and second line settings. The results of two randomized phase III studies (FU/folinic acid +/- oxaliplatin) are expected. The oxaliplatin/cisplatin combination as salvage regimen had produced significant antitumoral activity (response rate: 45%) in resistant/refractory ovarian cancer. Finally, recent experimental and clinical data have outlined the potential interest in the development of this new original platinum compound. New single agent phases II are expected in other tumor types as well as new oxaliplatin combinations are ongoing (phase I trials of oxaliplatin/CPT-11 and of oxaliplatin/carboplatin, phase II study of oxaliplatin-vinorelbine in lung cancer.

Abstract
Ifosfamide is an analogue of cyclophosphamide active in the treatment of numerous tumours. Although its use by continuous infusion seems to be responsible for less toxicity, differences of efficacy and toxicity, observed according to its doses and schedules of administration, still remain debated. The objective of this study was to assess the toxicity of high-dose ifosfamide given by continuous infusion over 6 days and its therapeutic activity in various advanced tumours. Twenty-six patients were treated with 14 g/m2 ifosfamide, an equal dose of MESNA, and routine granulocyte- or granulocyte/macrophage-colony-stimulating factor during the intercycle. Courses were repeated every 3 weeks until disease progression or unacceptable toxicity occurred; 75 cycles were administered. The mean number of cycles per patient was 3 (range 1-11). Extrahaematological toxicity was manageable in most patients, WHO grade II or more neurological (5 patients) and renal (5 patients) toxicities occurring in those heavily pretreated with platinum compounds and presenting peritoneal disease. WHO grade III or more neutropenia occurred in 60% of cycles, while grade III-IV thrombocytopenia and anaemia were observed in 19% of them. Three partial responses (germ-cell tumour, chondrosarcoma, soft-tissue sarcoma) and one complete response (metastatic osteosarcoma) were assessed, all in patients with tumours refractory or resistant to standard-dose ifosfamide, which underlines the possibility of circumventing the resistance to ifosfamide given in conventional schedules. The present results confirm previous reports of changes in the therapeutic index of ifosfamide according to its dose and administration schedule.

Abstract
BACKGROUND Desmoplastic small round-cell tumor has been identified as a neoplasm with multidirectional immunohistochemical, and molecular features of this tumor sets it apart as a pathologic entity. The optimal treatment remains to be determined. METHODS Five adult patients were treated according to a uniform first-line chemotherapy program including cisplatin, etoposide, cyclophosphamide, and either doxorubicin or epirubicin. Chemotherapy was delivered after initial surgery in the four patients with intra-abdominal presentation, and at relapse in the fifth patient who had a paratesticular primary tumor. RESULTS All 4 patients with intra-abdominal disease experienced stability lasting from 4 to 9 months. Only one objective persistent complete response was observed; this was in the patient with a paratesticular primary. No salvage treatment was active in the other four patients who died of progressive disease. CONCLUSIONS Our experience to a certain degree of chemosensitivity for desmoplastic small round-cell tumors. Despite aggressive treatments, survival rates remain disappointing. Other therapeutic modalities are needed to improve these results.

Abstract
PURPOSE To assess the tolerance, toxicity, and antitumoral activity of the weekly combination of cisplatin (CDDP) and interferon alfa-2a (IFNalpha2a) in advanced diffuse malignant mesothelioma (DMM). PATIENTS AND METHODS Twenty-six patients with DMM (23 pleural and three peritoneal), previously untreated, were enrolled onto this study between August 1991 and December 1992. All patients had measurable disease defined by computed tomographic (CT) scan and diagnostic confirmation by histopathology review panel. IFNalpha2a (3 x 10(6) IU subcutaneously on days 1 to 4) and CDDP (60 mg/m2/wk on day 2) were given weekly. Initially planned as a 5-weeks-on/3-weeks-off treatment cycle, poor patient tolerance observed in the first 12 patients treated (group A) led to schedule adaptation with a shorter treatment sequence and prolongation of the rest period (4 weeks on/4 weeks off) in the following 14 patients (group B). At least two cycles were administered to each patient in the absence of tumor progression. RESULTS Twenty-six patients were assessable for toxicity and 25 for efficacy (World Health Organization [WHO] criteria). Sixty-eight cycles of IFN/CDDP were given, with a median of three cycles per patient (range, one to five). Toxicity was mainly clinical, with progressive anorexia, asthenia, and prolonged nausea/emesis; these side effects have limited treatment acceptance in many patients. Thrombocytopenia and leukopenia were rarely noted as treatment-limiting toxicities. Objective responses (all partial) were obtained in 10 patients (95% confidence interval [CI], 20% to 60%). The median response duration was 11 months (range, 6 to 18). The median time to progression (TTP) for the whole cohort was 6 months and the median survival time was 12 months (range, 5 to 32). Objective responders had a significantly longer median TTP (21 months) and survival time (25 months) than nonresponders (3 and 8 months, respectively). CONCLUSION The results of this pilot phase I-II study show encouraging antitumor activity in this traditionally resistant tumor, even if the specific contribution of IFN remains speculative and needs further clinical research. Our ongoing program is exploring the dose-intensity impact of IFN dose within the same combination.

Abstract
Thirteen patients with intra-abdominal malignancies entered a phase I study of fluorouracil (5-FU) given by continuous infusion (96 h) iv and ip, simultaneously, and modulated by high-dose folinic acid-iv. Severe but reversible stomatitis was the only dose-limiting toxicity at a dose of 5-FU of 550 mg/m2/day. Local toxicity (5-FU-induced abdominal pain) was a significant side effect in patients receiving more than 1 cycle. The pharmacokinetic advantage of 5-FU-ip was confirmed in our study (ratio AUC peritoneum/plasma between 160 and 328). The systemic exposure to 5-FU (plasmatic AUC ranging from 73.4 to 173.21 microM) and to AF were found in efficacious ranges. The recommended dose of 5-FU iv and ip is 500 mg/m2/day. This regimen is feasible and may potentially have application for adjuvant chemotherapeutic programs after surgery for colorectal cancer.

Abstract
PURPOSE A prospective clinical study was performed to determine the incidence of high-dose continuous intravenous infusion fluorouracil (5FU-CIV) cardiotoxicity. PATIENTS AND METHODS Three hundred sixty-seven patients who were given first-cycle high-dose 5FU-CIV were monitored for cardiac function by clinical examination, ECG, and laboratory tests. 5FU-CIV was administered during a 96- or 120-hour period at doses that ranged from 600 to 1,000 mg/m2/d. Associated drugs included cisplatin (56%), mitomycin (12.5%), folinic acid (leucovorin) (7%), and others (14%). Thirty-nine patients (10.5%) received 5FU as a single agent. RESULTS 5FU-induced cardiac events occurred in 28 patients (7.6%; 95% confidence interval, 4.9% to 10.3%). Nine of them had a history of cardiac disease. Primary tumors included head and neck (n = 13), gastrointestinal (n = 6), breast (n = 3), and others (n = 6). The mean onset time of cardiac symptoms was 3 days (range, 2 to 5). Inaugural symptoms included angina pectoris (n = 18), hypotension (n = 6), hypertension (n = 5), malaise (n = 4), dyspnea (n = 2), arrhythmia (n = 1), or sudden death (n = 1). At 5FU discontinuation, six patients' cardiac symptoms returned to baseline, but 21 patients experienced unstable angina (n = 8), hypotension/cardiovascular collapse (n = 11), pulmonary edema (n = 1), or sudden death (n = 4). The lethality rate was 2.2% (five sudden deaths plus three irreversible collapses). ECG showed repolarization changes (ST segment deviation; T-wave inversion) in 65% and/or diffuse microvoltage in 22% of the patients who presented with cardiac events. Echocardiography showed partial or global hypokinesia in nine of the 16 patients who were examined, and one case of prolonged akinesia. Cardiac enzymes rarely showed an increase (n = 2). In severe but reversible cases, clinical, ECG, and echographic parameters returned to baseline status within 48 hours after the drug discontinuation. A fluorine 19 nuclear magnetic resonance (19F NMR) analysis of urine was performed on 14 patients; six had cardiac symptoms and eight did not. Fluoroacetate (FAC), a known cardiotoxic compound, was detected in all cases. CONCLUSION In our study, the incidence of high-dose 5FU-CVI cardiotoxicity was 7.6%. The hypothesis of a toxic cardiomyopathic process requires further confirmation.
