Immediate listing for liver transplantation versus standard care for Child-Pugh stage B alcoholic cirrhosis: a randomized trial.

BACKGROUND: Liver transplantation improves survival of patients with end-stage (Child-Pugh stage C) alcoholic cirrhosis, but its benefit for patients with stage B disease is uncertain. OBJECTIVE: To compare the outcomes of patients with Child-Pugh stage B alcoholic cirrhosis who are immediately listed for liver transplantation with those of patients assigned to standard treatment with delay of transplantation until progression to stage C disease. DESIGN: Randomized, controlled trial. SETTING: 13 liver transplantation programs in France. PATIENTS: 120 patients with Child-Pugh stage B alcoholic cirrhosis and no viral hepatitis, cancer, or contraindication to transplantation. INTERVENTIONS: Patients were randomly assigned to immediate listing for liver transplantation (60 patients) or standard care (60 patients). MEASUREMENTS: Overall and cancer-free survival over 5 years. RESULTS: Sixty-eight percent of patients assigned to immediate listing for liver transplantation and 25% of those assigned to standard care received a liver transplant. All-cause death and cirrhosis-related death did not statistically differ between the 2 groups: 5-year survival was 58% (95% CI, 43% to 70%) for those assigned to immediate listing versus 69% (CI, 54% to 80%) for those assigned to standard care. In multivariate analysis, independent predictors of long-term survival were absence of ongoing alcohol consumption (hazard ratio, 7.604 [CI, 2.395 to 24.154]), recovery from Child-Pugh stage C (hazard ratio, 7.633 [CI, 2.392 to 24.390]), and baseline Child-Pugh score less than 8 (hazard ratio, 2.664 [CI, 1.052 to 6.746]). Immediate listing for transplantation was associated with an increased risk for extrahepatic cancer: The 5-year cancer-free survival rate was 63% (CI, 43% to 77%) for patients who were immediately listed and 94% (CI, 81% to 98%) for those who received standard care. LIMITATION: Restriction of the study sample to alcoholic patients may limit the generalizability of results to other settings. CONCLUSION: Immediate listing for liver transplantation did not show a survival benefit compared with standard care for Child-Pugh stage B alcoholic cirrhosis. In addition, immediate listing for transplantation increased the risk for extrahepatic cancer. FUNDING: The French National Program for Clinical Research.

Colonoscopic screening of first-degree relatives of patients with large adenomas: increased risk of colorectal tumors.

BACKGROUND & AIMS: The risk of developing colorectal neoplasia is not well established among family members of individuals with large adenomas, and screening strategies remain under debate in this population. This study aimed at quantifying the risk of colorectal adenomas and cancers using colonoscopic screening in first-degree relatives of patients with large adenomas. METHODS: This case-control study was performed in 18 endoscopic units of French nonuniversity hospitals. A colonoscopy was offered to first-degree relatives of 306 index cases with adenomas > or =10 mm if they were alive, aged 40-75 years, and could be contacted by the index case. Among them, 168 were examined and matched for age, sex, and geographical area with 2 controls (n = 307). Controls were randomly selected from 1362 consecutive patients aged 40-75 years having undergone a colonoscopy for minor symptoms. RESULTS: The prevalence of large adenomas and cancers was 8.4% and 4.2%, in relatives and controls, respectively. Odds ratios (ORs) associated with a history of large adenomas in relatives were 2.27 (95% confidence interval [CI], 1.01-5.09) for cancers or large adenomas, 1.21 (95% CI, 0.68-2.15) for small adenomas, and 1.56 (95% CI, 0.96-2.53) for all colorectal neoplasia. The risk of large adenomas and cancers was higher in relatives of index cases younger than 60 years (OR, 3.82; 95% CI, 0.92-15.87) and when the index case had large distal adenomas (OR, 3.14; 95% CI, 1.27-7.73). CONCLUSIONS: First-degree relatives of patients with large adenomas are at increased risk of developing colorectal cancers or large adenomas. This result has implications for screening in this high-risk population.

Chemoradiation followed by surgery compared with chemoradiation alone in squamous cancer of the esophagus: FFCD 9102.

PURPOSE: Uncontrolled studies suggest that chemoradiation has similar efficacy as surgery for esophageal cancer. Therefore, a randomized trial was carried out to compare, in responders only, chemoradiation alone with chemoradiation followed by surgery in patients with locally advanced tumors. PATIENTS AND METHODS: Eligible patients had operable T3N0-1M0 thoracic esophageal cancer. Patients received two cycles of fluorouracil (FU) and cisplatin (days 1 to 5 and 22 to 26) and either conventional (46 Gy in 4.5 weeks) or split-course (15 Gy, days 1 to 5 and 22 to 26) concomitant radiotherapy. Patients with response and no contraindication to either treatment were randomly assigned to surgery (arm A) or continuation of chemoradiation (arm B; three cycles of FU/cisplatin and either conventional [20 Gy] or split-course [15 Gy] radiotherapy). Chemoradiation was considered equivalent to surgery if the difference in 2-year survival rate was less than 10%. RESULTS: Of 444 eligible patients, 259 were randomly assigned; 230 patients (88.8%) had epidermoid cancer, and 29 (11.2%) had glandular carcinoma. Two-year survival rate was 34% in arm A versus 40% in arm B (hazard ratio for arm B v arm A = 0.90; adjusted P = .44). Median survival time was 17.7 months in arm A compared with 19.3 months in arm B. Two-year local control rate was 66.4% in arm A compared with 57.0% in arm B, and stents were less required in the surgery arm (5% in arm A v 32% in arm B; P < .001). The 3-month mortality rate was 9.3% in arm A compared with 0.8% in arm B (P = .002). Cumulative hospital stay was 68 days in arm A compared with 52 days in arm B (P = .02). CONCLUSION: Our data suggest that, in patients with locally advanced thoracic esophageal cancers, especially epidermoid, who respond to chemoradiation, there is no benefit for the addition of surgery after chemoradiation compared with the continuation of additional chemoradiation.

Safety of cisplatin combined with continuous 5-FU versus bolus 5-FU and leucovorin, in metastatic gastrointestinal cancer (FFCD 9404 randomised trial).

BACKGROUND: The objective of this phase III study was to compare the safety and efficacy of FLP (modulation of 5-FU (Fluorouracil) by folinic acid or leucovorin (LV) and cisplatin vs. FP (5-FU combined with Cisplatin) as a first line chemotherapy in advanced oesophageal, gastric and pancreatic cancer. PATIENTS AND METHODS: 232 patients with measurable lesions were randomised to receive at the first cycle either FP (arm A: 5-FU 800 mg/m2/d in continuous infusion 5 days and cisplatin 100 mg/m2 on day 1 or 2), or FLP (arm B: LV, 100 mg/m2/d in bolus 5 days, followed by 5-FU 350 mg/m2/d in 1 h infusion 5 days and cisplatin 100 mg/m2 on day 1 or 2). In case of no grade 3-4 haematological and diarrhoea toxicity, the dose of 5-FU was increased to 1000 mg/m2/d and 400 mg/m2/d in the two arms respectively, for the subsequent cycles until disease progression. RESULTS: The distribution of primary tumours was: 19 squamous cell carcinoma of the oesophagus, 19 oesophageal adenocarcinoma, 91 gastric and 97 pancreatic adenocarcinoma. Safety remained acceptable and comparable in the two arms except for the severe grade 3-4 mucositis, which was lower in arm B (4.5 vs. 16.4%, p < 0.009). Efficacy in terms of tumour response and survival was similar in the two arms, showing an objective response rate (after external review) of 18.6% (95% confidence interval (CI) 11.4-25.8%) in arm A vs. 15% (95% CI 8.5-21.6%) in arm B, an overall median survival of 24 weeks in arm A vs. 24.7 in arm B (p = 0.83) and a progression-free median survival of 12.4 weeks vs. 12.1 in arms A and B, respectively (p = 0.91). CONCLUSION: The FLP regimen is substantially equivalent to FP in terms of safety and quality of life, as well as for antitumour efficacy in these carcinomas; the only slight advantage of FLP in this study concerns mucositis. Based on these results, FLP could be used as an alternative to FP when appropriate.

Genetic polymorphisms of MMP1, MMP3 and MMP7 gene promoter and risk of colorectal adenoma.

BACKGROUND: Matrix metalloproteinases (MMP) have been shown to play a role in colorectal cancer (CRC). More recently, MMP1, MMP3 and MMP7 functional gene promoter polymorphisms have been found to be associated with CRC occurrence and prognosis. To document the role of MMP polymorphisms in the early step of colorectal carcinogenesis, we investigated their association with colorectal adenoma risk in a case-control study comprising 295 patients with large adenomas (LA), 302 patients with small adenomas (SA) and 568 polyp-free (PF) controls. METHODS: Patients were genotyped using automated fragment analysis for MMP1 -1607 ins/del G and MMP3 -1612 ins/delA (MMP3.1) polymorphisms and allelic discrimination assay for MMP3 -709 A/G (MMP3.2) and MMP7 -181 A/G polymorphisms. Association between MMP genotypes and colorectal adenomas was first tested for each polymorphism separately and then for combined genotypes using the combination test. Adjustment on relevant variables and estimation of odds ratios were performed using unconditional logistic regression. RESULTS: No association was observed between the polymorphisms and LA when compared to PF or SA. When comparing SA to PF controls, analysis revealed a significant association between MMP3 -1612 ins/delA polymorphism and SA with an increased risk associated with the 6A/6A genotype (OR = 1.67, 95% CI: 1.20-2.34). Using the combination test, the best association was found for MMP3.1-MMP1 (p = 0.001) with an OR of 1.88 (95% CI: 1.08-3.28) for the combined genotype 2G/2G-6A/6A estimated by logistic regression. CONCLUSION: These data show a relation between MMP1 -1607 ins/del G and MMP3 -1612 ins/delA combined polymorphisms and risk of SA, suggesting their potential role in the early steps of colorectal carcinogenesis.

Randomized controlled trial of tamoxifen in advanced hepatocellular carcinoma.

PURPOSE: Randomized studies on tamoxifen treatment of hepatocellular carcinoma (HCC) produced conflicting results. The aim of this study was to assess the efficacy of tamoxifen administration in improving overall survival of patients with advanced HCC. PATIENTS AND METHODS: A total of 420 patients with HCC who were not suitable for surgery or local treatment were randomly assigned between April 1995 and May 2000: 210 in the control group and 210 in the tamoxifen group (20 mg/d orally). Patients with WHO performance status greater than 2, belonging to Child-Pugh class C, or with serum creatinine greater than 130 mumol/L were not eligible. RESULTS: Tolerance was good and the main reported adverse effects were thrombophlebitis (three patients), nausea (two patients), and hot flushes (three patients). Outcome did not differ between the two treatment arms: estimated median survival was 4.8 and 4.0 months in the tamoxifen and in the control groups, respectively (P = .25). Univariate analysis showed significant association of survival with age, Okuda stage, WHO performance status, Child-Pugh class, intrahepatic tumor stage, alpha-fetoprotein serum concentration, and presence of extrahepatic spread, portal vein thrombosis, hepatomegaly, or hepatalgia. In a Cox proportional hazards model we found a significant beneficial effect of tamoxifen on survival in patients belonging to Okuda I or II stages. CONCLUSION: In this large study, tamoxifen did not improve the survival of patients with advanced HCC, but there is a suggestion that patients without major hepatic insufficiency seem to have some survival benefit. New trials involving this specific population are warranted.

Randomized multicenter phase II trial of a biweekly regimen of fluorouracil and leucovorin (LV5FU2), LV5FU2 plus cisplatin, or LV5FU2 plus irinotecan in patients with previously untreated metastatic gastric cancer: a Federation Francophone de Cancerologie Digestive Group Study--FFCD 9803.

PURPOSE: To determine the efficacy and safety of a biweekly regimen of leucovorin (LV) plus fluorouracil (FU) alone or in combination with cisplatin or irinotecan in patients with previously untreated metastatic gastric adenocarcinoma and to select the best arm for a phase III study. PATIENTS AND METHODS: One hundred thirty-six patients (two were ineligible) were enrolled onto the randomized multicenter phase II trial. Patients received LV 200 mg/m(2) (2-hour infusion) followed by FU 400 mg/m(2) (bolus) and FU 600 mg/m(2) (22-hour continuous infusion) on days 1 and 2 every 14 days (LV5FU2; arm A), LV5FU2 plus cisplatin 50 mg/m(2) (1-hour infusion) on day 1 or 2 (arm B), or LV5FU2 plus irinotecan 180 mg/m(2) (2-hour infusion) on day 1 (arm C). RESULTS: The overall response rates, which were confirmed by an independent expert panel, were 13% (95% CI, 3.4% to 23.3%), 27% (95% CI, 14.1% to 40.4%), and 40% (95% CI, 25.7% to 54.3%) for arms A, B, and C, respectively. Median progression-free survival and overall survival times were 3.2 months (95% CI, 1.8 to 4.6 months) and 6.8 months (95% CI, 2.6 to 11.1 months) with LV5FU2, respectively; 4.9 months (95% CI, 3.5 to 6.3 months) and 9.5 months (95% CI, 6.9 to 12.2 months) with LV5FU2-cisplatin, respectively; and 6.9 months (95% CI, 5.5 to 8.3 months) and 11.3 months (95% CI, 9.3 to 13.3 months) with LV5FU2-irinotecan, respectively. CONCLUSION: Of the three regimens tested, the combination of LV5FU2-irinotecan is the most promising and will be assessed in a phase III trial.

Evaluation of the management of rectal cancers before and after the consensus conference in France.

OBJECTIVES: Population-based registries are the best way to draw a picture of the management of a disease. The purpose of this study was to analyse therapeutic modalities for rectal cancers in seven French areas in 1990 and 1995, before and just after a consensus conference devoted to this topic. METHODS: A community-based series of 945 patients (402 in 1990, 543 in 1995) with rectal cancer was used to assess therapeutic modalities and stage at diagnosis. RESULTS: Colonoscopy was performed in most of the cases (90% in 1990 and 1995). There was significant change between 1990 and 1995 in stage at diagnosis and cancer resection. The rate of continence-preserving operations was similar in 1990 and in 1995, as was the rate of adjuvant radiotherapy. There was a shift between 1990 and 1995 from postoperative radiotherapy to preoperative radiotherapy. There was an increase in the use of adjuvant chemotherapy. CONCLUSION: Changes in the management of rectal cancer in France over the past few years have concerned mainly resection rate, stage at diagnosis and adjuvant therapy. The recommendations of the consensus conference were followed only partly, in particular for adjuvant preoperative radiotherapy, which has not reached its full development, and adjuvant chemotherapy, which tends to be overprescribed, considering how little is known about its effectiveness.

Management of hepatitis C patients: a French population-based study.

AIMS: Our aim was to assess the proportion of patients in a well-defined population reaching specialized medical care after hepatitis C diagnosis. METHODS: Hepatitis C-positive patients recorded in the population-based registry of Cote-d'Or, an administrative district in France, constituted the study population. RESULTS: Between 1994 and 1999, new hepatitis C-positive serology was diagnosed in 847 patients, of whom 690 were eligible for this study. A total of 135 patients had not been given specialized medical care after diagnosis; among them, 50.4% had a normal serum alanine transferase level at diagnosis, 62.2% had risk factors related to lifestyle (drug addiction, sexual risk...), and 26.7% were current alcoholics. The 555 other patients were involved in specialized medical care after diagnosis: 42.7% had a liver biopsy and 27.0% were treated. Treatment was carried out more often in males than in females (OR: 1.67; P<0.005), and in patients less than 65 years old (OR: 2.94; P<0.0002). Nearly 30.5% of patients with a Metavir score greater than A1F1 did not undergo treatment. CONCLUSION: This study shows that in a general population at least one patient out of five with hepatitis C infection remains outside the health care system. It also reveals that management practices vary with gender. Further surveys are needed to better understand this phenomenon.

Association between diabetes and stroke subtype on survival and functional outcome 3 months after stroke: data from the European BIOMED Stroke Project.

BACKGROUND AND PURPOSE: Although diabetes is a strong risk factor for stroke, it is still unclear whether stroke subtype, severity, and prognosis are different in diabetic and nondiabetic patients. We sought to evaluate stroke features, prognosis, and functional outcome in patients with diabetes compared with patients without diabetes. METHODS: In a European Union Concerted Action involving 7 countries and 4537 patients hospitalized for a first-in-a-lifetime stroke, defined according to the Oxfordshire Community Stroke Project criteria, we collected data on demographics, risk factors, clinical presentation, and outcome. We used logistic regression to examine the relationship between diabetes and outcome at 3 months (disability, handicap, and death), controlling for risk factors, clinical presentation, and demographics. RESULTS: Overall, diabetes was present in 937 patients (21%). Diabetic patients, compared with those without diabetes, were more likely to have limb weakness (P<0.02), dysarthria (P<0.001), ischemic stroke (P<0.001), and lacunar cerebral infarction (P=0.03). At 3 months, the case fatality rates were not higher in the diabetic groups (P=0.33). Handicap (Rankin Scale) and disability (Barthel Index) were significantly higher in diabetic patients (P=0.005 and P=0.016, respectively). CONCLUSIONS: Stroke in diabetic patients has a specific clinical pattern and a poor prognosis in terms of motor function, which emphasizes the need for early diagnosis and treatment of every case of diabetes.
