Multicentre randomised phase III trial comparing Tamoxifen alone or with Transarterial Lipiodol Chemoembolisation for unresectable hepatocellular carcinoma in cirrhotic patients (Fédération Francophone de Cancérologie Digestive 9402).

The FFCD 9402 multicentre phase III trial was designed to compare the effects of the combination of Transarterial Lipiodol Chemoembolisation (TACE) and tamoxifen with tamoxifen alone on overall survival and quality of life in the palliative treatment of hepatocellular carcinoma with cirrhosis. From 1995 to 2002, 138 patients were randomised between the two groups. One hundred and twenty three patients were eligible including 61 in the Tamoxifen group and 62 in the TACE group. Baseline characteristics were similar: Child-Pugh class A: 70%, alcoholic cirrhosis: 76%, Okuda stage I: 71%, multinodular tumour: 70% and segmental portal vein thrombosis: 10%. At 2years, the overall survival was 22% and 25% in the Tamoxifen and TACE groups (P=.68), respectively. Multivariate analysis identified four independent prognostic factors for survival: alpha-fetoprotein (AFP)>400ng/mL (P=.008), abdominal pain (P=.011), hepatomegaly (P=.023) and Child-Pugh score (P=.032). The Spitzer Index level assessing the quality of life during follow-up did not differ between the two groups (P=.70). Amongst patients with stage Okuda I, the 2-year overall survival was 28% in the Tamoxifen group and 32% in the TACE group (P=.58). In this subgroup, two prognostic factors were statistically significant for survival: AFP>400ng/mL (P=.004) and Spitzer Index (P=.013) as shown by multivariable analysis. In conclusion, this study suggests that TACE improves neither the survival nor the quality of life in patients with HCC and cirrhosis.

Changing of hepatitis C virus genotype patterns in France at the beginning of the third millenium: The GEMHEP GenoCII Study.

This cross-sectional study aimed to investigate, during a short period between 2000 and 2001, in a large population of patients with chronic hepatitis C, the epidemiological characteristics of hepatitis C virus (HCV) genotypes in France. Data from 26 referral centres, corresponding to 1769 patients with chronic hepatitis C were collected consecutively during a 6-month period. HCV genotyping in the 5'-non-coding region (NCR) was performed in each center using the line probe assay (LiPA, in 63% of cases), sequencing (25%) or primer-specific polymerase chain reaction (PCR) (12%). HCV genotypes 1a, 1b, 2, 3, 4, 5, non-subtyped 1 and mixed infection were found in 18, 27, 9, 21, 9, 3, 11 and 1% of our population, respectively. HCV genotype distribution was associated with gender, age, source and duration of infection, alanine aminotransferase (ALT) levels, cirrhosis, alcohol consumption, hepatitis B virus (HBV) and human immunodeficiency virus (HIV) coinfection. In multivariate analysis, only the source of infection was the independent factor significantly associated with genotype (P = 0.0001). In conclusion, this study shows a changing pattern of HCV genotypes in France, with i.v. drug abuse as the major risk factor, an increase of genotype 4, and to a lesser extent 1a and 5, and a decrease of genotypes 1b and 2. The modification of the HCV genotype pattern in France in the next 10 years may require new therapeutic strategies, and further survey studies.

[Association of celiac disease and esophageal small cell carcinoma]. / Association d'une maladie coeliaque et d'un carcinome de l'oesophage à petites cellules.

BACKGROUND: Coeliac disease is known to favor the development of neoplasia. Coeliac disease associated with small-cell carcinoma of the esophagus has not been reported to date. CASE REPORT: A 51-year-old man with coeliac disease known for several years was hospitalized for epigastric pain. Work-up led to the diagnosis of small-cell carcinoma of the lower esophagus. The patient was treated with 6 cycles of chemotherapy using an etoposide-ciplatinum protocol associated with 60 Gy radiotherapy starting at the third cycle. The patient has remained in complete remission 2 years after diagnosis. DISCUSSION: Small-cell carcinoma of the esophagus is an exceptional finding in a patient with coeliac disease. Chemotherapy associated with radiotherapy has been successful in our patient.

Interobserver agreement on endoscopic diagnosis of bleeding peptic ulcers.

BACKGROUND: The aim of this prospective study was to evaluate the interobserver agreement of stigmata of recent hemorrhage of bleeding peptic ulcers. METHODS: Sixty-one consecutive adult patients were enrolled in the study and nine (three junior and six senior) endoscopists reviewed standardized video recordings of endoscopic examinations. Interobserver agreement was evaluated using the kappa (kappa) index, intraclass correlation coefficient, and proportion of agreement. Observer bias and poorly trained observers were investigated. RESULTS: Interobserver agreement was very good for oozing (kappa = 0.68), good for clot (kappa = 0.51), poor for spurting (kappa = 0.29) and visible vessels (kappa = 0.33), and excellent for the absence of stigmata (kappa = 0.82). Observer bias sometimes occurred and the number of poorly trained observers was low. The kappa indexes were significantly better in senior than in junior investigators: 0.48 +/- 0.16 versus 0.37 +/- 0.26, respectively, p < 0.05. The agreement between the in vivo evaluation and video tape recordings (intraobserver agreement) was good (kappa = 0.60 +/- 0.19). There was no training phenomenon between the first and the second half of the patient group. CONCLUSIONS: The endoscopic classification of bleeding ulcers might be simplified by limiting grading to a few classes. Special attention should be paid to the training of endoscopists.

Endoscopic detection of early esophageal cancer in a high-risk population: does Lugol staining improve videoendoscopy?

BACKGROUND: The aim of this study was to prospectively compare the diagnostic accuracy of videoendoscopy, with and without Lugol staining, for the detection of esophageal cancer in alcoholic or smoking patients older than 40 years. METHODS: Daily alcohol and tobacco consumption and overt and latent symptoms were noted. The 158 patients included were examined by videoendoscopy and with Lugol dye. RESULTS: The mean consumption of alcohol and tobacco was 86 +/- 49 gm/day for 26 +/- 11 years, and 30 +/- 18 pack-years, respectively. Twenty-five patients had no symptoms. Before Lugol staining, 12 patients had endoscopically identified cancerous lesions. After Lugol staining, 13 patients had 17 esophageal cancers, 3 of which were high-grade dysplasia. The prevalence of esophageal cancer was 8.2%: 95% CI [4,14]. Dye-free surfaces were significantly larger than the endoscopic patterns observed before Lugol staining (11.6 +/- 9.2 cm2 vs 1.4 +/- 1.7 cm2; p < 0.02). CONCLUSIONS: In an alcoholic smoking population, the prevalence of esophageal cancer detected by endoscopy is high and not related to symptoms described by patients. Lugol staining only moderately improves the diagnostic accuracy of videoendoscopy; its main advantage is the assessment of the mucosal extension of esophageal cancer.

[Necrolytic migrating erythema without glucagonoma]. / Erytheme necrolytique migrateur sans glucagonome.

INTRODUCTION: The glucagonoma syndrome is an uncommon but well-known entity associating erythema necroticans migrans (ENM) with glucagonoma. CASE REPORT: A 43-year-old man with a past history of alcoholic cirrhosis and ascitis was hospitalized for skin disorders which had developed over the past 4 months. Centrifugal erythematous skin lesions were observed, some with non-turgid bullae and marginal desquamation, others with an erosive center. Lesions first appeared on the hands then diffused widely without involving the periorifical areas, folds and lower limbs. Laboratory results revealed an anemia, hypovitaminosis K, cholestatic liver failure, a beta-gamma block and low zinc levels. Histology study of the skin biopsy demonstrated a << Neapolitan trench >> image suggestive of ENM. A paraneoplasic syndrome and pancreas tumor were not found. Despite supplementation with zinc, amino acids and vitamins, the patient died from his liver disease. DISCUSSION: There have been 4 cases of ENM reported in the literature, all in cirrhosis patients, two of which had low zinc levels. Our case is thus the third with cirrhosis and low zinc. Bazex's syndrome, acrodermatitis enteropathica, annular chronic lupus erythematosis and annular superficial pemphigus were eliminated as possible diagnoses. The failure of zinc and amino acid supplementation would favor the secondary nature of the zinc deficiency and the predominant role of cirrhosis in this skin disease. The possible role of essential fatty acids in ENM is raised.

[Singular diaphragm-like colonic stricture and short-term administration of a non-steroidal anti-inflammatory drug]. / Diaphragme colique unique et prise brève d'anti-inflammatoire non stéroïdien.

A case of diaphragm-like stricture of the colon induced by non steroidal anti-inflammatory drug (diclofénac LP) is reported in a 65-year-old man who presented abdominal pain. Colonoscopy revealed ulcer in the transverse right colon. The patient gradually developed diaphragm-like stricture in the transverse right colon. A right hemicolectomy was performed.

[Gastroesophageal reflux after percutaneous endoscopic gastrostomy. Scintigraphic study in 51 patients]. / Reflux gastro-oesophagien après gastrostomie percutanée endoscopique. Etude scintigraphique chez 51 malades.

Gastro-oesophageal reflux and pneumonia are complications of enteral feeding. We report our experience of a scintigraphic technique in 51 patients fed by percutaneous endoscopic gastrostomy. The technique was very well tolerated; only one patient (2 percent) had vagal discomfort. A quantitative isotopic study using Tc 99 m labelled enteral infusion demonstrated episodes of reflux in 26 patients (51 percent). The reflux was greater than 6 percent of recording time in 15 patients. All patients with pneumonia had positive scintigraphy. Our study suggests that reflux is frequent after percutaneous endoscopic gastrostomy and constant in patients with pneumonia.

[Severe gastroduodenal ulcer hemorrhage. Treatment with endoscopic injections of an epinephrine solution]. / Hémorragies ulcéreuses gastroduodénales graves. Traitement par injections endoscopiques d'une solution d'épinéphrine.

Eighty-three patients (more than one half of whom were at high surgical risk) presenting with haemorrhages from a gastric or duodenal ulcer were treated with endoscopic injections of an epinephrine-hypertonic saline mixture. The overall rate of definitive haemostasis was 83 p. 100. Depending on the degree of haemorrhagic activity, this rate was 64 p. 100 in pulsatile lesions, 90.5 p. 100 in oozing lesions, 85.7 p. 100 in cases with visible vessels and 81.2 p. 100 when signs of recent bleeding were present. There was no dangerous complication related to the technique. The overall survival rate was 67.5 p. 100 and 20 out of the 26 deaths were due to other causes than haemorrhages. On follow-up, 94.7 p. 100 of the ulcers healed under antisecretory treatment within the usual length of time. This simple, effective and inexpensive technique is suggested as initial treatment of gastric or duodenal haemorrhages in subjects at high surgical risk, especially since the haemorrhage has no influence on the course of the ulcer.
