[Prognostic value of E-cadherin expression in hepatocellular carcinoma].

Expression of E-cadherin (E-cad) was investigated immunohistologically in 91 cases of operated hepatocellular carcinomas. An alteration of E-cad immunodetection was found in 56% of tumours. These alterations were correlated with histopathologic features of prognostic value including tumour size (> 3 cm), high nuclear grade and mitotic index. Patients with down-regulated E-cad expression had statistically significant shorter survival than the others. Although E-cad immunodetection was an independent prognostic factor, the Cox multivariate analysis showed that its prognostic value was low when compared to other prognostic factors.

[Recurrence after surgical treatment of epidermoid cancers of the esophagus. Therapeutic approach in 19 patients].

OBJECTIVES: The aim of this study was to report the management of 19 patients with recurrence of esophageal squamous cell carcinoma after surgical treatment. PATIENTS-METHODS: Nineteen patients with loco-regional recurrent invasion (n = 13) or metastasis (n = 6) of esophageal squamous cell carcinoma were included. Four of the 13 patients with loco-regional recurrent invasion had tracheal involvement. The treatment of the recurrence was a combined radiochemotherapy (n = 12) for loco-regional recurrent invasion in 11 cases and for metastasis in 1 case, associated with a tracheal prosthesis in 1 patient. The other treatments were chemotherapy alone (n = 5), esophageal prosthesis (n = 1) and surgical treatment (n = 1). RESULTS: There were 7 objective responses among the 12 patients treated with combined radiochemotherapy and none in the group treated with chemotherapy alone. Grade 3-4 toxicity was noticed in 2 cases (severe mucositis). Survival rate of the 19 patients was 52.6% at 1 year and 13.1% at 2 years; it was linked with general health (P = 0.09) and with tracheal involvement (P = 0.04). Survival rate of the 12 patients treated by combined radiochemotherapy was higher: 66% at 1 year and 22.2% at 2 years (median survival time = 16 months). CONCLUSION: Active medical treatment of recurrence of esophageal squamous cell carcinoma by combined radiochemotherapy can provide a median survival time of 16 months, with a moderate toxicity.

[Pelvic recurrence of cancers of the uterine cervix. A study of a series of 49 cases].

BACKGROUND: Pelvic recurrence of cervical cancer is a life-threatening event for patients. The main therapeutic challenge is to locally control such relapses. We present our experience of the surgical treatment of pelvic cervical cancer relapses. PATIENTS AND METHODS: From July 1980 to January 1994, 49 patients underwent a surgical procedure for pelvic cervical cancer relapse. Forty four tumor relapses were localized in the pelvis and 5 were associated with distant metastases. Surgery was performed alone in 31 cases and in association with radiotherapy in 18 cases. Median follow-up was 34 months. RESULTS: The treatment was curative in 49% of cases. There was a significant correlation between the initial stage, the site of tumor relapse and surgical curability. Overall actuarial survival was 44% and 24% at 2 and 5 years, respectively. In the curative treatment group, actuarial survival was 71% and 47% at 2 and 5 years, respectively. There was a major surgical complication in 14 cases: 11 reoperations were performed. Thirteen patients are alive of whom 12 with no evidence of disease (median follow-up; 36 months). A local control was achieved in 53% of cases. Age and site of relapse significantly influenced survival. CONCLUSIONS: The results of this study are comparable with other surgical series despite our less favorable patient selection. For patients experiencing pelvic side-wall infiltration, surgical treatment is a worthwhile palliation in selected cases because it is often the only available therapeutic option.

[Transanal excision of rectal tumors. New applications of the endo-GIA forceps].

Two new applications of the endo-GIA technique are presented for endoluminal intrarectal resection of benign or malignant tumors of the lower or middle part of the rectum. These procedures allow resection of sessile lesions with a large implantation base. Depending on the pathology and the type of implantation, resection can either be total or via the musculosa. Results have been good with this simple procedure which allows total tumor resection and an uneventful post-operative period.

A western surgical experience of peripheral cholangiocarcinoma.

The aim of this retrospective study was to analyse outcome in 31 European patients operated on for peripheral cholangiocarcinoma between 1988 and 1995 (hilar cholangiocarcinoma was excluded). Before 1992, in addition to conventional resection, patients with irresectable tumour and with no extrahepatic metastasis underwent total hepatectomy with liver transplantation. Mild abdominal pain was the most frequent presenting clinical sign (11 of 31 patients) and jaundice was present in only four patients. Preoperative histological findings were available for 20 patients but the diagnosis was correct in only eight of these. Nineteen patients had curative surgery: 17 underwent conventional resection and two had total hepatectomy with liver transplantation. Major hepatectomy was performed in 12 of 17 cases, extended to the caudate lobe in five, to the bile duct confluence in four and to the retrohepatic vena cava in one. Postoperative mortality and morbidity rates were three and seven of 19 patients respectively, median survival was 15 months, and actuarial 1-, 2- and 5-year survival rates were 67, 40 and 32 per cent respectively. Twelve patients had only exploratory laparotomy because of the presence of extrahepatic metastasis or irresectable tumour. The invasive nature of peripheral cholangiocarcinoma can explain the limited number of resectable cases and the particularly unfavourable prognosis. Total hepatectomy does not provide survival benefit. Conventional surgery remains the only effective treatment, even for patients with advanced stage tumours.

Budd-Chiari syndrome secondary to intracardiac extension of hepatocellular carcinoma. Two cases treated by radical resection.

Two young women presenting Budd-Chiari syndrome as the primary manifestation of hepatocellular carcinoma with intracardiac extension were treated by debulking of the atrium and inferior vena cava under extracorporeal circulation and major hepatectomy. The first patient who was treated in a single procedure died during the immediate postoperative period. The second patient who was treated in two steps died of meningeal and pulmonary metastases 12 months later. Clinical findings and surgical strategy for this rare condition are discussed in the light of 6 previously reported surgical cases.

High incidence of colic anastomotic leakage complicating upper abdominal en bloc evisceration for cancer: a 47-patient series.

BACKGROUND/AIMS: The purpose of this study was to analyze the early outcome of en bloc extended resection for upper abdominal locally advanced cancer. METHODOLOGY: A retrospective medical chart review was performed in 47 consecutive patients who underwent an upper abdominal en bloc resection for cancer involving multiple organs or structures at Paoli-Calmettes Institute and Conception Hospital from October 1988 through April 1997. A third of patients underwent a resection of 4 sus mesocolic organs or more. RESULTS: The postoperative morbidity and mortality rate were respectively, 57% and 19%. Despite a high number of theoretically risky procedures including pancreatic resection and pancreatojejunostomy, total gastrectomy and esophagojejunostomy, total hepatectomy and liver transplantation, the higher percentage of complication was found with colic anastomosis. Five of the 30 patients (17%) who underwent a colic anastomosis developed a colic anastomotic leakage, 4 patients were reoperated and 2 patients died. CONCLUSIONS: Because of this unacceptably high rate of complications, we propose to systematically perform a protective stoma when an upper abdominal evisceration includes a colic anastomosis.

Mechanically stapled esophagojejunostomy. Results of a prospective series of 176 cases.

BACKGROUND/AIMS: To evaluate the reliability of stapled esophagojejunostomy. MATERIAL AND METHODS: We studied a non-selected prospective series of 176 consecutive total gastrectomies (169 cancers, 7 benign pathologies). RESULTS: Hand-sewn esophagojejunostomy was performed 5 times after failure of the stapled esophagojejunostomy. There were fourteen hospital deaths (8%), and 63 patients (36%) presented complications. There were 5 anastomotic leaks (2.8%) but non were responsible for deaths. In these 5 cases, there had been an incident during construction of the esophagojejunostomy. Such an incident was the only significant risk factor for an anastomotic leak: 17% after an incident and 0% in the absence of an incident (p < 0.001). We observed no cases of anastomotic stricture. CONCLUSION: Stapled esophagojejunostomy is a reliable technique when technical precautions are taken. It is easier to reproduce than hand-sewn esophagojejunostomy and has demonstrated low specific morbidity and no direct mortality.
