Abstract
Few studies concerning the potential genetic effects of diagnostic radionuclides used in nuclear medicine have been reported. The aim of this study was to evaluate the biological and cytogenetic consequences of two technetium 99m-labelled radiopharmaceuticals. Ultrastructural modifications of pulmonary cells were first investigated after injection of 99mTc labelled microspheres in the rat. On the same irradiated cells, nuclear expression of p53 protein was assessed using immunohistochemistry. Despite very high previously calculated doses delivered to pulmonary cells, no morpholological cell damage and no significant increase of nuclear expression of the p53 were noted. There was no correlation between the calculated dose and the ultrastructural biological damage. Secondly, a specific in vitro curve, activity/number of unstable chromosomal aberrations, corresponding to physical characteristics of 99mTc, was established to verify the potentiality of 99mTc to induce such aberrations. In vivo, cytogenetic effects were assessed on blood samples of 5 patients with various arthrosic and periarthrosic diseases obtained after bone scintigraphy. Aberration frequencies of both in vitro and in vivo irradiated lymphocytes were determined using the classical Fluorescence Plus Giemsa technique. No cytogenetic effects appeared with the routinely 99mTc injected activities as predicted by the in vitro curve.

Abstract
Imaging and endoscopic techniques have taken an increasing part in the management of gastroenterological disorders. Among these techniques, FDG-PET imaging has emerged as a powerful tool in the management of several cancer diseases, including tumors of the digestive tract. In particular, the role of PET for diagnosing and staging recurrent colorectal cancers, and for differentiating mass forming pancreatitis from carcinoma is now well established. In this review, we will briefly discuss the place of PET imaging in the work-up of the tumors of the digestive tract.

Abstract
OBJECTIVE We evaluated prognostic factors in 34 patients discharged from hospital after surgical resection for oesophageal squamous cell carcinoma. MATERIAL AND METHODS There were 22 males and 12 females; mean age was 59.3 years (range 42-77 years). Preoperative neoadjuvant treatment consisted in chemotherapy alone in three patients and in combined radiochemotherapy in 14. Digestive continuity was restored with a gastric transplant in 26 patients and a colonic graft in 8. Surgery was curative in 28 patients and palliative in 6. There were three stage I, 14 stage II, 13 stage III, and 4 stage IV diseases. In 19 patients the lymph nodes were invaded. The tumour was well differentiated in 17 patients, moderately in 9, and poorly in 8. RESULTS Follow-up ranged from 2 to 100 months. Overall median postoperative survival was 21 months. By univariate analysis, factors influencing survival were curative surgery (p = 0.04), stage (p = 0.006), and nodal involvement (p = 0.0003). Nodal involvement was an independent prognostic factor by multivariate analysis (p = 0.0002). Patient age and sex, perioperative transfusion, digestive transplant, tumour local extension, grade of differentiation, and distant metastasis did not influence survival. Also, we did not observe any significant benefit of preoperative or postoperative chemotherapy or radiochemotherapy. CONCLUSIONS Nodal involvement was the most important prognostic factor influencing survival. Therefore, an earlier diagnosis of oesophageal cancer in a less advanced stage is important to improve survival rates. Our study could not confirm the benefit of neoadjuvant therapy in terms of late survival.

Abstract
BACKGROUND Positron emission tomography (PET) has been shown useful for the staging of patients with various carcinomas. METHODS We have applied this technique to 54 cases of colorectal carcinoma and compared it to conventional imaging techniques. RESULTS PET had moderately higher sensitivity and specificity than conventional techniques to detect individual lesion sites (75% vs 70.8% and 63% vs 21% respectively). It detected the same number of patients with recurrences (35/39) but overestimated disease less frequently (5 cases vs 12). PET favorably influenced therapeutic management in 17 patients, indicating different or additional surgery in 9 while avoiding surgery with curative intent or unnecessary surgery in 8. In 5 cases, erroneous information provided by PET could be corrected by conventional imaging techniques. CONCLUSION We conclude that PET appears to provide complementary information useful for staging patients with colorectal carcinomas. It can significantly modify patients management. These data should be confirmed by a prospective study.

Abstract
Transmission of undiagnosed malignancy with the graft is a dramatic complication of liver transplantation. Alternatives in the management of the recipients of livers, harvested from donors with malignancy diagnosed shortly after transplantation, are either early re-transplantation or close follow-up without re-operation. We reported 4 cases of liver recipients whose allografts were harvested from donors who were diagnosed with malignancy shortly after the liver transplantation. One recipient underwent re-transplantation, and the three other allografts were not removed. No recipient developed recurrence in the follow-up. While graft removal may be the only way to avoid tumor recurrence in recipients of liver graft harvested from donor with malignancy, close follow-up without re-operation may also be considered. The risk of tumor transferral may depend on the histopathological aggressiveness and metastatic potential of the donor tumor, and may be low for low-grade, local tumors. This risk should be evaluated by analyzing large series, using databases of Eurotransplant or United Network for Organ Sharing.

Abstract
The orthotopic liver transplantation (OLT) program of the University of Liège was initiated in 1986. Between 1986 and December 1998, 150 adult OLT have been performed in our institution, including 18 liver retransplantations, 1 combined heart and liver transplantation and 3 combined liver and kidney transplantations. The aim of this study was to report the last 3 years of our experience. From January 1996 to November 1998, we performed 50 OLT on 49 patients. Three were retransplantations and two were combined liver and kidney transplantations. Fourty-three patients were transplanted for chronic liver disease and 6 for acute or subacute hepatopathy. Mean waiting time on the list was 4 weeks. Immunosuppression was based on triple therapy (cyclosporin A/tacrolimus, steroids, azathioprine), with steroid and azathioprine withdrawal in most of the patients after 3 months. In the chronic liver disease group, operative (< 30 days) survival was 95% (peroperative myocardial infarction in 2 patients). In the acute liver disease group, postoperative survival was 66%. No perioperative death occurred in 1997 and 1998. Actuarial one year survival was 87%. In our experience, OLT has become a safe procedure.

Abstract
Fulminant hepatic failure is an infrequent but dreadful disease, occurring usually in young patients. Despite fulminant hepatic failure is reversible in most of the cases, some patients develop brain edema and intracranial hypertension, which are the most common cause of death in these patients. Liver transplantation significantly improves the prognosis of selected patients in who precise criteria predict a low chance of survival. This review summarizes the modern standard of care of patients with fulminant hepatic failure, with particular underlining of the management of brain oedema and intracranial hypertension.

Abstract
OBJECTIVE Functional evaluation of digestive transplants after oesophagectomy for cancer. MATERIAL AND METHODS We evaluated alimentary comfort and quality of life and performed a videofluoroscopy (radiocinema) in 34 patients who were alive and disease-free one year or more after oesophagectomy for malignancy. There were 22 males and 12 females; mean age was 64 years. Twenty-three patients had a gastric pull-up and 11 a colonic graft. Mean follow-up was 36 months (range: 12-100 months). Possible correlations between clinical symptoms and radiographic observations were studied with Fisher's exact test. RESULTS Most-cited symptoms were gurgling in 16 patients, early fullness during eating in 15, diarrhea in 14, postprandial sweating in 9, pyrosis in 8, nocturnal cough in 7, and dysphagia in 5. Most patients considered the side effects of the operation as mild to moderate and mean rating of alimentary comfort was 7.6/10. Twenty-five patients qualified their quality of life as good, 8 as satisfactory, and 1 as poor. Twenty-nine patients led active lives. Videofluoroscopic evaluation showed that colonic grafts emptied mainly by gravity, while active contractions were observed in the antrum of gastric transplants. There was a significant correlation between alimentary symptoms and radiographic distension of the transplant. Oro-pharyngeal abnormalities, site of proximal anastomosis, nature, motility, or active versus passive emptying of the transplant did not correlate with clinical complaints. CONCLUSIONS In most patients quality of life and alimentary comfort are good after oesophagectomy and gastric or colonic interposition. Radiocinema is an adequate method to evaluate the dynamic of the transplant and shows a better emptying of gastric grafts, compared to colonic grafts, particularly when the proximal portion of the oesophagus triggers the progression.

Abstract
We report a case of hepatoportal sclerosis in a renal transplant patient treated with azathioprine. The initial symptom was ascites. On the biochemical level, there were cholestasis without cytolysis or hepatocellular insufficiency. A presinusoidal portal hypertension was found on haemodynamic studies, without portal thrombosis at CT-scan. A diagnosis of hepatoportal sclerosis was evoked on histology and attributed to azathioprine. This case gives an illustration of a classical albeit rare complication of azathioprine. The indolent pattern of the disease and the risk of variceal bleeding point out the need for a hepatic follow-up during the treatment.

Abstract
OBJECTIVE To determine prognosis factors influencing long-term survival after surgical resection for oesophageal adenocarcinoma or squamous cell carcinoma. MATERIAL AND METHODS Patients operated for oesophageal cancer between 1989 and 1995 were included in this study, excluding perioperative deaths. Were studied as potential prognosis factors: age, sex, operative intent, transfusion, digestive transplant, Barrett metaplasia, stage, tumoral extension (T), nodal involvement (N), distant metastases (M), tumoral differentiation, pre- or post-operative neoadjuvant treatment. RESULTS Follow-up was 2 to 100 months. Median survival was 21 months for squamous cell carcinoma, and 12 months for adenocarcinoma. By univariate analysis, factors influencing survival were, for squamous cell carcinoma: nodal involvement (N) (p = 0.0003), stage (p = 0.006), and operative intent (p = 0.04); for adenocarcinoma: tumoral differentiation (p = 0.0015), local extension (T) (p = 0.0022), stage (p = 0.0043), nodal involvement (N) (p = 0.0052), operative intent (p = 0.006), and distant metastases (p = 0.014). By multivariate analysis, independent prognosis factors were, for squamous cell carcinoma, nodal involvement (N) (p = 0.0002), and for adenocarcinoma, operative intent (p = 0.0018) and tumoral differentiation (p = 0.0014). CONCLUSIONS Diagnosis of oesophageal cancer at an early stage is the most important prognosis factor. This retrospective study failed to show any significant benefit from neoadjuvant treatment, in term of long-term survival. Patients with poor prognosis factors, such as determined by accurate preoperative staging, could potentially benefit from more aggressive multimodal therapies.

Abstract
BACKGROUND To assess surgical outcome after oesophagectomy, we reviewed operative techniques and postoperative course among 90 patients who underwent oesophageal resection for malignancies from January 1989 to December 1995. METHODS There were 73 males and 17 females; mean age was 64.2 years. Indications were squamous cell carcinoma in 49 patients and adenocarcinoma in 41. Preoperatively 7 patients had chemotherapy and 18 benefited from radiochemotherapy. There were 56 total thoracic oesophagectomies, with anastomosis in the neck in 34 patients and at the thoracic inlet in 22. In 34 cases operation was limited to distal oesophageal resections. Digestive continuity was restored with the stomach in 62 patients, with the colon in 24, and with a jejunal loop in 4. A feeding jejunostomy was constructed in 48 patients with a gastric transplant. RESULTS Mortality was 10% (9 patients), decreasing from 18.5% (before 1993) to 3.8% (since 1993). One patient died in the colonic graft group and 8 in the gastric pull-up group. Postoperative complications occurred in 9 patients after colonic interposition and in 23 after gastric pull-up; they consisted in pulmonary infection or insufficiency in 26 patients, cerebrovascular accident in one, renal insufficiency in 2, recurrent nerve palsy in 4, and anastomotic leakage in 6. Transhiatal approach was not associated with a decreased incidence of postoperative deaths or complications. Eighteen patients (72%) developed postoperative pulmonary complications after preoperative chemotherapy. CONCLUSION Oesophagectomy can be performed with low mortality. A colonic graft is not associated with an increased incidence of perioperative deaths or complications and is the substitute of choice when there is any question regarding gastric vascularization, or in young patients with long life expectancy. Preoperative neoadjuvant treatment significantly increases postoperative pulmonary complications.

Abstract
BACKGROUND Assessment of metastatic involvement of the liver remains a diagnostic challenge. The objective of this study was to evaluate the potential role of FDG PET in the detection of liver metastases. PATIENTS AND METHODS Sixty-four patients with malignancy and possible liver involvement were included. Liver metastases were present in 31 cases, demonstrated by histopathological analysis in 15 cases and by follow-up in 16 cases. The negative cases were confirmed by pathology in four cases, peroperative ultrasonography in 12 cases, and follow-up in 17 cases. Whole-body FDG PET was compared to CT (n = 53) and US (n = 43). RESULTS PET demonstrated a 97% sensitivity, an 88% specificity and a 92% accuracy, compared to 93%, 75% and 85%, respectively, for CT (P = NS). Concordant results were obtained in 44 of 64 patients (69%: 19 TP. 25 TN). PET provided new and accurate information in 15 of 64 patients (23.4%). PET demonstrated liver metastases in 11 patients in whom conventional methods yielded negative (two cases) or doubtful (nine cases) results. Four patients free of liver involvement were correctly staged with PET, while CT/US were equivocal. PET was erroneous in five of 64 cases (7.8%, four FP, one FN). CONCLUSIONS FDG PET allows an accurate screening of liver involvement in patients with malignancy. Combined with CT, it provides additional diagnostic information that could directly affect the management of these patients.

Abstract
Liver surgery is currently performed with minimal morbidity and mortality, mostly thanks to reduced intraoperative blood loss, achievable by various types of liver clamping. A better knowledge of the physiological and physiopathological changes caused by liver clamping is however still necessary. The "natural" evolution of biochemical and liver function tests after liver surgery have been described. This paper describes the hemodynamic changes observed with different types of clamping and discusses several ways in which liver clamping techniques might be improved.

Abstract
Some patients operated of a colo-rectal cancer can be selected to receive a post-operative adjuvant chemotherapy to decrease the risk of recurrence. The authors report the results of experimental works on intraperitoneal chemotherapy (IPC). At the laboratory, they showed that this option significantly reduced the risk of recurrences in the most frequent sites of colo-rectal cancer recurrences: liver, lymph nodes, peritoneum and the surgical site. Moreover, the survival of the treated animals was significantly prolonged compared to the controls. In human, they proved the feasibility of a intraperitoneal chemotherapy managed into the immediate post-operative period. Low morbidity, null mortality and the interesting preliminary carcinological results suggest the interest of such an option which could be confirmed by a randomized multi-centric study currently in preparation.

Abstract
Cancer of the various organs of the abdominal cavity accounts for approximately 40% of yearly deaths in western countries. A frequently contributing factor is peritoneal carcinomatosis. The traditional approach to peritoneal carcinomatosis has been to renounce further surgical treatment, and resort to palliative chemotherapy. Tumour mass reduction by surgical debulking alone does not benefit the patient. Over the past decade, studies have shown that surgical debulking, (cytoreduction), combined with synchronous intraperitoneal chemotherapy provides good, and occasionally spectacular, results. The most significant results were initially obtained in the treatment of peritoneal pseudomyxoma and further studies have demonstrated the effectiveness of this combined approach in the treatment of colon, gastric and ovarian cancer. The statistical benefit gained by such treatment is thus far indiscutable. It should also be noted that the addition of perioperative hyperthermia appears to increase the effectiveness of treatment. While awaiting further options for the treatment of peritoneal carcinomatosis, notably in the arena of immuno- or genetic therapy, it is certain that combined cytoreduction/intraperitoneal chemotherapy/hyperthermia, is a feasible approach with proven benefit that should be included in current clinical protocols.

Abstract
PET is a diagnostic method that creates high resolution, 3 dimensional tomographic images of the distribution of positron emitting radionuclides in the human body. Recent technological developments allow the use of whole-body PET devices in clinical oncology. 18FDG is a glucose analog transported and competitively used with glucose reflecting the increased glucose metabolism into malignant cells. Differential diagnosis between chronic pancreatitis and pancreatic cancer is already a well-documented indication. For initial staging of gastro-esophageal and colorectal tumours, results are preliminary but the clinical impact seems to be rather limited. At present, the major indication of FDG-PET is the detection and staging of colorectal cancer recurrences. FDG-PET allows the differentiation between scared tissue and tumour when structural imaging is often confusing. In the same time, the whole-body imaging capability provides unique information that can modify loco-regional and liver staging. Overall, FDG-PET affects the clinical management of 30 to 40% of these patients. Quantitative assessment of therapeutic response to chemotherapy regimen appears to be one of the most promising applications of FDG-PET. Since the most effective therapy of colorectal cancer are often surgical, the role of chemotherapy in colorectal cancer remains limited to adjuvant therapy and in advanced disease. However, FDG-PET could be of great value in assessing the response of oesophageal carcinomas to chemo-radio therapy, before surgery. In our experience, FDG-PET appears to be the first line diagnostic method in the detection and staging of colorectal recurrence and differential diagnosis of pancreatic tumour versus chronic pancreatitis.
