(1/16288) Intensive investigation in management of Hodgkin's disease.
Ninety-eight patients with clinically localised Hodgkin's disease underwent laparotomy and splenectomy to determine the extent of microscopic spread. In 68 patients the procedure was carried out for untreated disease apparently confined above the diaphragm. Abdominal disease cannot be confidently excluded on the basis of non-invasive investigation at presentation. Clinical assessment of splenic disease was unreliable unless gross splenomegaly was present. Pedal lymphography was accurate in assessing para-aortic and iliac disease but of no value in assessing other intra-abdominal lymph node involvement, including that of the mesenteric lymph node. Trephine bone marrow biopsy findings were normal in all patients before surgery, and only one patient was found to have diseased bone marrow by Stryker-saw biopsy at operation. Liver disease was identified at operation in nine patients, some of whom were asymptomatic with clinically undetectable splenic and nodal disease. Detailed clinical staging failed to detect disease in one-third of patients who underwent laparotomy. These studies show that if radiotherapy is to remain the treatment of choice for disease truly localised to lymph nodes a detailed staging procedure, including laparotomy and splenectomy, remains essential. The value of this potentially curative treatment is considerably diminished in the patient who has been inadequately staged. (+info)
(2/16288) Peripheral hepatojejunostomy as palliative treatment for irresectable malignant tumors of the liver hilum.
OBJECTIVE: To evaluate the concept of surgical decompression of the biliary tree by peripheral hepatojejunostomy for palliative treatment of jaundice in patients with irresectable malignant tumors of the liver hilum. SUMMARY BACKGROUND DATA: Jaundice, pruritus, and recurrent cholangitis are major clinical complications in patients with obstructive cholestasis resulting from malignant tumors of the liver hilum. Methods for palliative treatment include endoscopic stenting, percutaneous transhepatic drainage, and surgical decompression. The palliative treatment of choice should be safe, effective, and comfortable for the patient. METHODS: In a retrospective study, surgical technique, perioperative complications, and efficacy of treatment were analyzed for 56 patients who had received a peripheral hepatojejunostomy between 1982 and 1997. Laparotomy in all of these patients had been performed as an attempt for curative resection. RESULTS: Hepatojejunostomy was exclusively palliative in 50 patients and was used for bridging to resection or transplantation in 7. Anastomosis was bilateral in 36 patients and unilateral in 20. The 1-month mortality in the study group was 9%; median survival was 6 months. In patients surviving >1 month, a marked and persistent decrease in cholestasis was achieved in 87%, although complete return to normal was rare. Among the patients with a marked decrease in cholestasis, 72% had no or only mild clinical symptoms such as fever or jaundice. CONCLUSIONS: Peripheral hepatojejunostomy is a feasible and reasonably effective palliative treatment for patients with irresectable tumors of the liver hilum. In patients undergoing exploratory laparotomy for attempted curative resection, this procedure frequently leads to persistent-although rarely complete-decompression of the biliary tree. In a few cases it may also be used for bridging to transplantation or liver resection after relief of cholestasis. (+info)
(3/16288) Risk of major liver resection in patients with underlying chronic liver disease: a reappraisal.
OBJECTIVE: To explore the relation of patient age, status of liver parenchyma, presence of markers of active hepatitis, and blood loss to subsequent death and complications in patients undergoing a similar major hepatectomy for the same disease using a standardized technique. SUMMARY BACKGROUND DATA: Major liver resection carries a high risk of postoperative liver failure in patients with chronic liver disease. However, this underlying liver disease may comprise a wide range of pathologic changes that have, in the past, not been well defined. METHODS: The nontumorous liver of 55 patients undergoing a right hepatectomy for hepatocellular carcinoma was classified according to a semiquantitative grading of fibrosis. The authors analyzed the influence of this pathologic feature and of other preoperative variables on the risk of postoperative death and complications. RESULTS: Serum bilirubin and prothrombin time increased on postoperative day 1, and their speed of recovery was influenced by the severity of fibrosis. Incidence of death from liver failure was 32% in patients with grade 4 fibrosis (cirrhosis) and 0% in patients with grade 0 to 3 fibrosis. The preoperative serum aspartate transaminase (ASAT) level ranged from 68 to 207 IU/l in patients with cirrhosis who died, compared with 20 to 62 in patients with cirrhosis who survived. CONCLUSION: A major liver resection such as a right hepatectomy may be safely performed in patients with underlying liver disease, provided no additional risk factors are present. Patients with a preoperative increase in ASAT should undergo a liver biopsy to rule out the presence of grade 4 fibrosis, which should contraindicate this resection. (+info)
(4/16288) Intrahepatic recurrence after curative resection of hepatocellular carcinoma: long-term results of treatment and prognostic factors.
OBJECTIVE: This study aimed to evaluate the long-term results of treatment and prognostic factors in patients with intrahepatic recurrence after curative resection of hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA: Recent studies have demonstrated the usefulness of re-resection, transarterial oily chemoembolization (TOCE), or percutaneous ethanol injection therapy (PEIT) in selected patients with intrahepatic recurrent HCC. The overall results of a treatment strategy combining these modalities have not been fully evaluated, and the prognostic factors determining survival in these patients remain to be clarified. METHODS: Two hundred and forty-four patients who underwent curative resection for HCC were followed for intrahepatic recurrence, which was treated aggressively with a strategy including different modalities. Survival results after recurrence and from initial hepatectomy were analyzed, and prognostic factors were determined by univariate and multivariate analysis using 27 clinicopathologic variables. RESULTS: One hundred and five patients (43%) with intrahepatic recurrence were treated with re-resection (11), TOCE (71), PEIT (6), systemic chemotherapy (8) or conservatively (9). The overall 1-year, 3-year, and 5-year survival rates from the time of recurrence were 65.5%, 34.9%, and 19.7%, respectively, and from the time of initial hepatectomy were 78.4%, 47.2%, and 30.9%, respectively. The re-resection group had the best survival, followed by the TOCE group. Multivariate analysis revealed Child's B or C grading, serum albumin < or = 40 g/l, multiple recurrent tumors, recurrence < or = 1 year after hepatectomy, and concurrent extrahepatic recurrence to be independent adverse prognostic factors. CONCLUSIONS: Aggressive treatment with a multimodality strategy could result in prolonged survival in patients with intrahepatic recurrence after curative resection for HCC. Prognosis was determined by the liver function status, interval to recurrence, number of recurrent tumors, any concurrent extrahepatic recurrence, and type of treatment. (+info)
(5/16288) Tumour ablation and hepatic decompensation rates in multi-agent chemoembolization of hepatocellular carcinoma.
Thirty-seven cirrhotic patients with 62 hepatocellular carcinoma (HCC) foci--most Child-Pugh class B or C and/or with large, inoperable tumours--underwent 148 sessions of transcatheter arterial chemoembolization (TACE) using lipiodol, doxorubicin and cisplatin. Treatment efficacy was assessed by serial hepatic arteriography in 34/37 (91.9%) patients and abdominal CT scanning in 3/37 (8.1%) patients. Child-Pugh status was determined prior to each treatment session. Varying degrees of control of tumour neovascularity occurred for a median 390 days (range 90 to > 1680 days) in 33/34 (97.1%) patients in whom progress hepatic arteriography was performed. Ablation of tumour neovascularity occurred in 6/6 (100%), 4/12 (33.3%) and 6/16 (37.5%) patients with HCC diameters < 4 cm, 4-7 cm and > 8 cm, respectively (p < 0.02). Significantly more sessions were required for ablation of larger tumours (p < 0.05). Recurrent HCC was detected in 50% of patients after a median 240 days (range 60-1120 days). Deterioration in Child-Pugh status followed a session of TACE on 19/148 (12.8%) occasions but resulted in unscheduled hospitalization on only 4/148 (2.7%) occasions, the highest incidence (8.3%) in Child-Pugh C patients. Actuarial survival was 27/36 (75.0%) at 6 months, 17/34 (50.0%) at 12 months, 14/34 (41.2%) at 18 months, 9/31 (29.0%) at 24 months and 4/27 (14.8%) at 36 months. Multi-agent TACE with lipiodol, doxorubicin and cisplatin provides a useful anti-tumour effect, even in cirrhotic patients with large HCCs. The incidence of clinically significant deterioration in hepatic function due to ischaemia of non-tumorous liver is acceptably low, even in Child-Pugh C patients. (+info)
(6/16288) Detection of liver metastases from pancreatic cancer using FDG PET.
We evaluated the potential of the glucose analog [18F]fluorodeoxyglucose (FDG) as a PET tracer for the hepatic staging in 168 patients designated for resective pancreatic surgery. METHODS: Metastatic liver disease was confirmed or excluded during surgery or with CT follow-up for at least 6 mo. Proven metastases were then retrospectively identified on preoperative CT (gold standard). Hepatic PET scans of all patients were interpreted blindly. Any focal FDG uptake was considered malignant. Both proven hepatic metastases and suspicious hepatic PET lesions were then compared, lesion by lesion, with CT. Standardized uptake values (SUV) and tumor-to-liver ratios (T/L) were determined for the most intense lesion of each patient. RESULTS: Sensitivity of FDG PET was 68% (15 of 22 patients). The lesion detection rate was 97% (28 of 29 metastases) for lesions >1 cm and 43% (16 of 37 metastases) for lesions < or = 1 cm. Specificity was 95% (138 of 146 patients). Six of eight patients with false-positive results had marked intrahepatic cholestasis (versus 3 of 15 patients with true-positive lesions), one had an infrahepatic abscess and one had a right basal pulmonary metastasis. The SUV and T/L were 4.6+/-1.4 and 2.3+/-1.1, respectively, for malignant lesions and 4.1+/-1.5 and 1.9+/-0.3, respectively, for false-positive lesions and therefore are of limited value. CONCLUSION: FDG PET provides reliable hepatic staging for lesions >1 cm. False-positive results are associated with the presence of marked intrahepatic cholestasis. For lesions < or = 1 cm, FDG PET can define malignancy in 43% of suspicious CT lesions in the absence of dilated bile ducts. (+info)
(7/16288) Clinical significance of circulating anti-p53 antibodies in European patients with hepatocellular carcinoma.
p53 alterations are considered to be predictive of poor prognosis in hepatocellular carcinoma (HCC) and may induce a humoral response. Anti-p53 serum antibodies were assessed by enzyme-linked immunosorbent assay (ELISA) using purified recombinant human p53 on 130 European HCC patients before treatment and during the clinical course of the disease. p53 immunohistochemistry was performed on tumours from the 52 patients who underwent surgery, and DNA sequencing analysis was initiated when circulating anti-p53 antibodies were detected. Nine (7%) HCC patients had anti-p53 serum antibodies before treatment. During a mean period of 30 months of follow-up, all the negative patients remained negative, even when recurrence was observed. Of the nine positive patients, eight were still positive 12-30 months after surgery. The presence of anti-p53 serum antibodies was correlated neither with mutation of the p53 gene nor the serum alpha-fetoprotein levels and clinicopathological characteristics of the tumours. However, a greater incidence of vascular invasion and accumulation of p53 protein were observed in the tumours of these patients (P<0.03 and P<0.01 respectively) as well as a better survival rate without recurrence (P = 0.05). In conclusion, as was recently shown in pancreatic cancer, anti-p53 serum antibodies may constitute a marker of relative 'good prognosis' in a subgroup of patients exhibiting one or several markers traditionally thought to be of bad prognosis.

(8/16288) Gallstones, cholecystectomy and risk of cancers of the liver, biliary tract and pancreas.
To examine the association between gallstones and cholecystectomy, we conducted a nationwide population-based cohort study in Denmark. Patients with a discharge diagnosis of gallstones from 1977 to 1989 were identified from the Danish National Registry of Patients and followed up for cancer occurrence until death or the end of 1993 by record linkage to the Danish Cancer Registry. Included in the cohort were 60 176 patients, with 471 450 person-years of follow-up. Cancer risks were estimated by standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) stratified by years of follow-up and by cholecystectomy status. Among patients without cholecystectomy, the risks at 5 or more years of follow-up were significantly elevated for cancers of liver (SIR = 2.0, CI = 1.2-3.1) and gallbladder (SIR = 2.7, CI = 1.5-4.4) and near unity for cancers of extrahepatic bile duct (SIR = 1.1), ampulla of Vater (SIR = 1.0) and pancreas (SIR = 1.1). The excess risk of liver cancer was seen only among patients with a history of hepatic disease. Among cholecystectomy patients, the risks at 5 or more years of follow-up declined for cancers of liver (SIR = 1.1) and extrahepatic bile duct (SIR = 0.7), but were elevated for cancers of ampulla of Vater (SIR = 2.0, CI = 1.0-3.7) and pancreas (SIR = 1.3, CI = 1.1-1.6). These findings confirm that gallstone disease increases the risk of gallbladder cancer, whereas cholecystectomy appears to increase the risk of cancers of ampulla of Vater and pancreas. Further research is needed to clarify the carcinogenic risks associated with gallstones and cholecystectomy and to define the mechanisms involved. (+info)
