Induction cisplatin-irinotecan followed by concurrent cisplatin-irinotecan and radiotherapy without surgery in oesophageal cancer: multicenter phase II FFCD trial.

A recent phase I study showed that weekly cisplatin, irinotecan and concurrent radiotherapy can be administered with moderate toxicity in patients with oesophageal cancer. Patients with no prior treatment and oesophageal cancer stage I to III, performance status <3, caloric intake >1,500 kcal day(-1) were included. Chemotherapy, with cisplatin 30 mg m(-2) and irinotecan 60 mg m(-2), was administered at days 1, 8, 22, 29, and concurrently with radiotherapy at days 43, 50, 64 and 71. Radiotherapy was delivered with 50 or 50.4 Gy in 25 fractions/5 weeks. Forty-three patients were included, 10 stage I, 19 stage II and 14 stage III. Mean age was 59.2 years (range 44-79). A total of 30 out of 43 (69.8%) patients underwent all planned treatment. During induction chemotherapy, 14 severe toxicities of grade 3 or 4 in 10 patients (23.3%) were reported with 57.1% due to haematoxicity. During chemoradiotherapy, 31 severe toxicities of grade 3 or 4 with 64.5% due to haematotoxicity were reported in 18 patients. One toxic death occurred (diarrhoea grade 4). The complete clinical response rate was 58.1% (95% CI: 43.4-72.8%). Overall survival rate at 1 and 2 years was 62.8%, (95% CI, 58.3-77.3%) and 27.9% (95% CI, 13.4-41.3%), respectively. In conclusion, cisplatin-irinotecan-radiotherapy is an active and well-tolerated regimen feasible in out-patients.

Impact of preoperative radiochemotherapy on postoperative course and survival in patients with locally advanced squamous cell oesophageal carcinoma.

BACKGROUND: The aim of this study was to determine the effect of neoadjuvant radiochemotherapy (RCT) on postoperative complications and survival after surgery for locally advanced oesophageal squamous cell carcinoma. METHODS: Postoperative course and survival were compared in 144 patients who had neoadjuvant RCT and 80 control patients who had surgery alone for locally advanced oesophageal squamous cell carcinoma (radiological stage T3, N0 or N1, M0). RESULTS: The two groups were comparable in terms of American Society of Anesthesiologists grade, age, sex, weight loss, tumour location, presence of lymph node metastasis and surgical approach. Postoperative mortality rates were 6.3 and 9 per cent (P=0.481), with morbidity rates of 40.3 and 41 percent (P=0.887) in the RCT and control group respectively. Complete resection (R0) rates were 74.3 and 48 percent respectively (P<0.001). Significant downstaging was observed in the RCT group (P<0.001), with 16.0 percent of patients having a complete pathological response. Median survival was 29 versus 15 months, and the 5-year survival rate 37 versus 17 percent (P=0.002) in RCT and control groups respectively. CONCLUSION: Neoadjuvant RCT significantly enhanced R0 resection and survival rates in patients with stage T3 oesophageal squamous cell carcinoma, with no increase in postoperative mortality and morbidity rates.

[Clinical practice guidelines: 2004 Standards, Options and Recommendations for the management of patient with adenocarcinoma of the stomach--radiotherapy].

CONTEXT: "The Standards, Options and Recommendations" (SOR) project, started in 1993, is a collaboration between the Federation of French Cancer Centers (FNCLCC), the 20 French regional cancer centers, and specialists from French Public Universities, General Hospitals and Private Clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. OBJECTIVES: To elaborate clinical practice guidelines for patients with stomach adenocarcinoma. These recommendations cover the diagnosis, treatment and follow-up of these tumors. METHODS: The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. The Standards, Options and Recommendations are thus based on the best available evidence and expert agreement. RESULTS: Adjuvant radiation therapy alone is not a standard treatment for patients with stomach adenocarcinoma. Adjuvant concomitant chemoradiotherapy is not a standard treatment for patients with stage II or III stomach adenocarcinoma R0, with Dl or D2 lymphadenectomy who have undergone surgery. Following surgical resection, adjuvant concomitant chemoradiotherapy should be proposed to patients without denutrition with a lymphadenectomy < Dl (fewer than 15 lymph nodes examined) and those with T3 and/or N+ tumours following the protocol used in the MacDonald trials (SWOG-9008) (Level of evidence B1). Adjuvant concomitant chemoradiotherapy can be administered to patients without denutrition with DI or D2 lymphadenectomy and with involvement of regional lymph nodes (N2 or N3).

Hepatic arterial infusion using pirarubicin combined with systemic chemotherapy: a phase II study in patients with nonresectable liver metastases from colorectal cancer.

BACKGROUND: A prospective phase II study was performed to determine the feasibility, efficacy and safety of arterial hepatic infusion (HAI) using pirarubicin combined with intravenous chemotherapy. PATIENTS AND METHODS: From December 1991 to April 1994, 75 patients with unresectable colorectal metastases confined to the liver were included in this multicenter study to receive intra-arterial hepatic pirarubicin and a systemic monthly regimen of 5-fluorouracil (5-FU) and folinic acid. Sixty-four patients were analyzed in the intention-to-treat analysis and 61 in the per-protocol analysis. RESULTS: Tolerance of this regimen was rather good; however, functional catheter problems were observed in 29 patients (45%) resulting in failure of HAI in 21 cases (33%) after a median of three cycles; vomiting grade 3 was present in 12.5% of patients, neutropenia grade 4 in 23% and alopecia grade 3 in 19%. The overall response rate was 31.9% in intention-to-treat analysis, and 39.3% in per-protocol analysis. Extrahepatic progression was reported in only 21.7% of patients. Time to hepatic progression and extra-hepatic progression was 8.3 and 15 months, respectively, in intention-to-treat analysis, and 11 and 18 months, respectively, in per-protocol analysis. Median survival was 19 and 20 months in intention-to-treat analysis and per-protocol, respectively. CONCLUSIONS: In our study, the combination of intra-arterial pirarubicin and intravenous chemotherapy demonstrated some efficacy and good tolerance in the treatment of isolated colorectal liver metastases. This treatment seems to prevent extra-hepatic spread and prolong survival time. The results of this study have to be confirmed by new trials using more active systemic chemotherapy.

Phase II trial of chronomodulated infusion of high-dose fluorouracil and l-folinic acid in previously untreated patients with metastatic colorectal cancer.

PURPOSE: To study tolerability and efficacy of an intensified chronomodulated schedule of fluorouracil (5-FU) and l-folinic acid (l-FA) as first-line treatment of metastatic colorectal cancer, 5-FU was given near individually determined dose-limiting toxicity in a multicenter phase II trial. PATIENTS AND METHODS: One hundred patients (68 men and 32 women, median age 62 years, World Health Organization performance status less-than-or-equal 2) with previously untreated and inoperable metastases received chronomodulated daily infusion of 5-FU/l-FA (from 10:00 PM to 10:00 AM with peak at 4:00 AM). 5-FU dose was escalated from 900 to 1,100 mg/m(2)/d with fixed dose of l-FA at 150 mg/m(2)/d for 4 days every 14 days. RESULTS: 5-FU dose escalation was achieved in 66% of the patients. Grade 3 to 4 toxicities mainly consisted of nausea or vomiting (14% of patients and 1.5% of courses), hand-foot syndrome (38% of patients and 8% of courses), mucositis (26% of patients and 4% of courses), and diarrhea (21% of patients and 2.3% of courses). Objective response rate (ORR) was 41% (95% confidence interval, 31.5% to 50.5%). Twenty patients underwent metastases surgery; among these, 12 had a complete resection. Median progression-free survival was 7 months. Median survival was 17 months; 28% of the patients were alive at 2 years and 18.6% at 3 years. CONCLUSION: The ORR achieved with intensified chronomodulated delivery of 5-FU/l-FA was nearly twice as high as that earlier obtained by our cooperative group using less intensive 5-FU/FA chronotherapy.

Vinorelbine and cisplatin in metastatic squamous cell carcinoma of the oesophagus: response, toxicity, quality of life and survival.

BACKGROUND: Vinorelbine and cisplatin are active against squamous cell oesophageal carcinoma. The purpose of this phase II study was to evaluate the efficacy and safety of vinorelbine plus cisplatin in previously untreated patients with metastatic squamous cell oesophageal carcinoma and to estimate the progression-free survival, overall survival and quality of life (QoL) of the patient population. PATIENTS AND METHODS: Seventy-one eligible patients were entered into a study of vinorelbine 25 mg/m2 on days 1 and 8 plus cisplatin 80 mg/m2 on day 1, every 3 weeks. Degree of dysphagia relief was monitored and QoL was measured using the EORTC QLQ-C30. RESULTS: All eligible patients were assessed for response and 24 achieved a confirmed partial response (33.8%; 95% confidence interval 23-46); the median duration of response was 6.8 months, progression-free survival was 3.6 months and median survival of the whole group was 6.8 months. Toxicity was mainly related to neutropenia (grade 3/4 in 41% of patients). At cycle 2, 43% of the patients reported at least a moderate improvement in global health status/QoL and 25% experienced a large improvement. CONCLUSIONS: Vinorelbine plus cisplatin represents a well-tolerated active palliative regimen for patients with advanced squamous cell carcinoma of the oesophagus. This combination may offer a better therapeutic index than cisplatin-5-fluorouracil.

A randomised trial comparing 5-FU with 5-FU plus cisplatin in advanced pancreatic carcinoma.

BACKGROUND: Chemotherapy is moderately efficient as a treatment for pancreatic adenocarcinoma, but patient survival and quality of life has improved with this modality in some trials. In a previous phase II trial, 5-fluorouracil (5-FU) plus cisplatin (FUP) yielded a 26.5% response rate and a 29% survival rate at 1 year. The present study aimed to compare FUP with 5-FU alone, which was the control arm in former Mayo Clinic trials. PATIENTS AND METHODS: Patients with untreated cytologically or histologically proven metastatic or locally advanced adenocarcinoma of the pancreas were deemed measurable or evaluable. Chemotherapy regimens consisted of a control FU arm (5-FU 500 mg/m(2)/day for 5 days) and the investigational FUP arm (continuous 5-FU 1000 mg/m(2)/day for 5 days plus cisplatin 100 mg/m(2) on day 1 or day 2). In both arms, chemotherapy was repeated at day 29. RESULTS: Two-hundred and seven patients from 18 centres were randomised: 103 in the FU arm and 104 in FUP arm. Treatment arms were balanced with respect to performance status grade 0-1 (83% versus 86%, respectively) and the presence of metastases (92% versus 89%, respectively). The median number of cycles administered was two in both arms (range 0-14). Five patients did not receive any chemotherapy and 45 received only one cycle. Toxicity (WHO grade 3-4) was lower with FU than with FUP (20% versus 48%, P <0.001), as was neutropenia (6% versus 23%), vomiting (4% versus 17%) and toxicity-related deaths (one versus four early in the trial). The response rate was low in both arms, but superior in the FUP arm: 12% versus 0% (intention-to-treat analysis, P <0.01). The survival rates at 6 months were 28% and 38% for the FU and FUP arms, respectively, and 1-year survival rates were 9% and 17% (log-rank test, P = 0.10). One-year progression-free survival was 0% with FU versus 10% with FUP (log-rank test, P = 0.0001). CONCLUSIONS: In advanced pancreatic carcinomas with a poor prognosis, FUP was superior to FU in terms of response and progression-free survival, but not in terms of overall survival. The low response rate is partly related to the number of patients who received only one cycle of chemotherapy. A more effective, better tolerated version of this FUP combination is needed.

Oral vinorelbine pharmacokinetics and absolute bioavailability study in patients with solid tumors.

BACKGROUND: Vinorelbine is a vinca alkaloid obtained by hemisynthesis, which makes the molecule more lipophilic than the other vincas. An injectable formulation is already marketed for the treatment of non small cell lung cancer (NSCLC) and advanced breast cancer (ABC). A new oral form has been developed and its file registration is being submitted. As part of its development, a clinical study was conducted to determine the absolute bioavailability and pharmacokinetics of oral vinorelbine administered as softgel capsules, and to evaluate its safety profile compared with intravenous administration. PATIENTS AND METHODS: Thirty-two patients with solid tumours were included in the study. Patients fasted and were randomised to receive vinorelbine on day 1, either as a 20 minute intravenous (i.v.) infusion of 25 mg/m2 or as softgel capsules at a dose of 80 mg/m2. Patients were treated with the alternate route after a one week wash-out period. Blood and urine samples for pharmacokinetic analysis were collected during each vinorelbine administration. Safety was assessed after each administration using the CALGB/expanded CTC classification. RESULTS: Twenty-four patients were eligible for pharmacokinetic evaluation. Oral vinorelbine was rapidly absorbed at 80 mg/m2 (Tmax 1.4 +/- 0.7 h) and showed a bioavailability of 43 +/- 14, and close to 40% based on AUC(last) and AUC(inf), respectively. A bioequivalence analysis was conducted on dosage-normalised blood exposures. Equivalence was demonstrated between 80 mg/m2 oral and 30 mg/m2 i.v., and between 60 mg/m2 oral and 25 mg/m2 i.v. The inter-individual variability was equivalent for both routes (CV: 38% and 39% for oral and i.v., respectively). A correlation was found in both methods between AUClast and % nadir variation in white blood cells (WBC) and polymorphonuclears (PMN). More cases of neutropenia (all grades pooled), leucopenia (grades 3-4 only) and nausea (grades 2-3) were induced by 80 mg/m2 oral vinorelbine than by 25 mg/m2 i.v. The greatest intensity of these effects, following oral administration, probably reflects the higher, observed drug exposure. CONCLUSION: At therapeutic dosage levels, pharmacokinetic behaviour and safety profiles were similar for both routes. The absolute bioavailability of the oral vinorelbine (new, soft gelatine capsule) was close to 40%. Inter-individual variability in drug exposure was equivalent in both routes. The pharmacokinetic/pharmacodynamic (PK/PD) relationship in haematological toxicity was independent of the routes of administration. Reliable, corresponding doses between oral and i.v. vinorelbine were established, which will result in bioequivalent AUC.

[Esophageal cancers].

Although slightly declining in France, the incidence rate of esophageal cancer remains amongst the highest seen in Europe, especially in Brittany, in the North as well as in Normandy. Alcohol and tobacco consumption remains the main risk factor for esophageal cancer in Western countries. Positive diagnosis of esophageal cancer is made by upper gastrointestinal endoscopy combined with biopsies. At present, surgery and definitive radiochemotherapy are two therapeutic options offering a chance to cure even though surgery remains the more frequently used treatment. Five-year-survival rate after apparently curative surgical resection or definitive radiochemotherapy remains only 20% in most population-based series. The studies that have examined the role of adjuvant treatments after surgical resection, have failed to demonstrate any improvement in overall or relapse-free survival. The pre-operative cytotoxic combined modality approaches with radiochemotherapy have shown improved relapse-free survival but still remains experimental. Finally, the symptomatic treatment of dysphagia might not be ignored either in locally, locally advanced, or in metastatic disease.

[Cancers of the stomach].

Although its declining incidence in most Western countries, gastric cancer remains a leading cause of cancer death. In France, it ranks second after colorectal cancer in terms of frequency. Chronic gastritis is the most frequent pathological condition that predispose to gastric cancer. One of the most important aetiological factor of gastric carcinogenesis is obviously the infection by Helicobacter pylori. Positive diagnosis of gastric cancer is made by upper gastrointestinal endoscopy combined with biopsies. Surgical resection is currently the only potentially curative treatment. However, the 5-year-survival rate after apparently curative surgical resection remains only 15% in Western populations. The studies on adjuvant treatment after surgical resection, have failed to demonstrate any improvement in overall or disease-free survival. Although promising in the locally advance setting, the pre-operative cytotoxic approach with or without radiation therapy remains experimental. In advanced disease the so-called ECF regimen results in delayed symptoms-free survival, increased survival (median: 9 months) and better quality of life.

A phase II study: docetaxel as first-line chemotherapy for advanced pancreatic adenocarcinoma.

The aim of this study was to evaluate the efficacy of docetaxel as first-line chemotherapy in patients with unresectable metastatic or locally advanced pancreatic adenocarcinoma and to further characterise the safety and pharmacokinetic profiles of docetaxel. 43 patients were enrolled into this phase II study. Treatment consisted of a 1-h infusion of docetaxel 100 mg/m2 every 3 weeks without premedication with corticosteroids until progression or unacceptable toxicity occurred. Dose modifications were planned for adverse events. Patients were observed for 1 month after the last docetaxel infusion, to document any late adverse events, with a follow-up every 3 months until death. Response rate and duration were the major efficacy endpoints. Response status was reviewed by an external independent panel. Pharmacokinetic analysis was performed during the first treatment cycle. 40 patients were evaluable for response, and all were evaluable for safety. After independent review, partial response was recorded in 6 patients (overall response rate, 15%; 95% confidence limit (CI), 7.7-29.8%) and stable disease was recorded in 15 patients (38%). The median duration of response was 5.1 months (range: 3.1-7.2). The median pain control time was 4.5 months (range: 0-8) and the median time to performance status worsening was 2.3 months (range: 0-4.5). Most patients 40 (93.0%) received a relative dose intensity of more than 70% of the planned dose. The incidence and severity of adverse events reflected the known safety profile for docetaxel. Docetaxel clearance was reduced in patients with elevated concentrations of hepatic enzymes or bilirubin. Docetaxel is an active agent for unresectable metastatic or locally advanced pancreatic adenocarcinoma.

Phase II trial of cystemustine, a new nitrosourea, as treatment of high-grade brain tumors in adults.

This study included 39 patients (37 evaluable, of whom 30 patients with recurrent gliomas and 7 patients with gliomas untreated by radiotherapy); they were enrolled into a phase II trial using a new nitrosourea, cystemustine, administrated every 2 weeks at 60 mg/m2 as a 15 min-infusion. Pathology at inclusion was (WHO classification): 14 glioblastomas, 20 grade 3-4 astrocytomas and 3 grade 3 oligodendrogliomas. Four partial responses have been obtained, giving an overall response rate of 10.8%. Four additional patients had a partial response, which for various reasons was not confirmed 4 weeks later; 12 patients had a stable disease for at least 8 weeks, 15 patients had progressive disease. Of the 4 responses, 2 were with a grade 3 oligodendroglioma and 2 glioblastoma. Toxicity (WHO grading) was mainly hematological: leukopenia (16.2% grade 3-4), neutropenia (29.7% grade 3-4), thrombopenia (27% grade 3-4). No other toxicity greater than grade 2 was observed. In conclusion, cystemustine at 60 mg/m2 has moderate clinical activity in relapsing glioma. Our results warrant further investigation of this agent with an increased dose or modified scheme.

Randomized comparison of prophylactic antidiarrheal treatment versus no prophylactic antidiarrheal treatment in patients receiving CPT-11 (irinotecan) for advanced 5-FU-resistant colorectal cancer: an open-label multicenter phase II study.

Delayed diarrhea is the main toxicity of irinotecan at the currently recommended dose of 350 mg/m2 30-minute intravenous infusion, once every 3 weeks. This phase II, multicenter, open-label, randomized study was primarily designed to evaluate the effect of a 15-day Tiorfan (racecadotril) treatment on the incidence and severity of irinotecan-induced delayed diarrhea. One hundred thirty-six patients with metastatic colorectal cancer who failed to respond to a 5-fluorouracil-based treatment received 714 cycles of irinotecan. The patients were randomly allocated either to group A (68 patients) and received Tiorfan (300 mg/day) from D0 to D15 or to group B (68 patients) with no prophylactic treatment. Delayed diarrhea occurred in 197 of 355 cycles (55%) in Group A and 203 of 344 cycles (59%) in Group B. grade III-IV diarrhea was reported in 17 of 40 compliant patients (42%) in group A and 31 of 68 evaluable patients (45%) in group B. No difference was observed between the two groups for delayed diarrhea characteristics, incidence, or severity. The response rate in 99 evaluable patients was 12.1% (6.4%-20.2%). This study has shown that Tiorfan given prophylactically at 300 mg/day has no effect on delayed diarrhea.

[Compassionate use of gemcitabine in advanced pancreatic cancer: a French multicentric study].

Advanced-stage surgically unresectable adenocarcinoma of the pancreas is highly lethal. Attempts to improve this survival with chemotherapy were dismal, until gemcitabin was shown to be clinically beneficial and to modestly improve survival. We started an open multicentric compassionate study of gemcitabine in advanced adenocarcinoma of the pancreas to assess those benefits. Of 74 patients who were enrolled, 46 were assessable for tumoral response (2 partial response, 18 stable disease, 24 progressing disease). A clinical benefit was obtained in 48% of assessable patients. Myelotoxicity, nausea and vomiting were the major side effect. The median event-free and overall survivals from study inclusion were 2. 5 and 5 months respectively. This study confirms that gemcitabine can be effective even in patients with pretreated advanced adenocarcinoma of the pancreas.

Results of a phase II trial with second-line cystemustine at 60 mg/m2 in advanced soft tissue sarcoma: a trial of the EORTC Early Clinical Studies Group.

The aim of this phase II trial was to examine the efficacy of a new nitrosourea, cystemustine, in soft tissue sarcoma. Between January 1990 and March 1991, 32 pretreated patients with advanced soft tissue sarcoma were enrolled. Cystemustine was given every 2 weeks at 60 mg/m2 via a 15-min i.v. infusion. All eligible patients were considered evaluable for response and toxicity (WHO criteria). Of the 32 enrolled patients, 4 were ineligible, leaving 28 evaluable patients. All but 1 had been pretreated: 6 with adjuvant chemotherapy, 18 patients with first-line palliative chemotherapy without nitrosourea, 3 with both treatments, and 18 had received radiotherapy. Median age was 54 years (range 20-73) and median performance status was 1 (0-2). One partial response (PR, duration 12 weeks), 2 stable disease and 25 progressions were observed, giving an overall response rate of 3.57% (confidence interval: 0.1-18.4%). Toxicity was mild, and was mainly neutropenia (no grade 3 or 4), thrombocytopenia (3.57% grade 3 and grade 4) and nausea-vomiting (no grade 3 or 4). It should be noted that the treatment for the patient who obtained a PR was third line with no previous response. Cystemustine with this schedule appears to have a low clinical activity and toxicity in advanced soft tissue sarcoma.
