RESUMO

AIMS: Computed tomography (CT) is the reference technique for evaluating response to chemotherapy. The potential helpfulness of tumour markers is debated. MATERIALS AND METHODS: From March 1997 to January 1999, 91 consecutive patients receiving chemotherapy for metastatic colorectal carcinoma underwent whole-body spiral CT, estimates of anti-carcinoembryonic antigen (CEA) and CA19-9 every 8 weeks. RESULTS: CEA and CA19-9 levels were above normal in 78 (85.7%) and 61 (67.5%) patients, respectively. Tumour response evaluation according to the RECIST criteria was obtained at 8-week evaluation in 83 (91%) patients. The positive predictive values (PPV) for response of a decrease of the marker levels were 53.8 for CEA and 41.7 for CA19-9 using a 30% decrease threshold, and 60/52.2, respectively, using a 50% decrease threshold. Meaningful PPV values (> 90%) for progression of an increase of the marker levels were only obtained using the 200% increase threshold for CEA alone or a combination of CEA and CA 19-9. A 100% CEA increase between baseline and the 8-week evaluation was correlated to overall survival (P = 0.0023). The need for a radiological confirmation of tumour progression could be avoided by the systematic dosage of tumour markers at baseline and after 8 weeks of treatment only in a sub-population of 13% of the patients with a 200% increase of CEA or CA 19-9 at 8 weeks. CONCLUSIONS: CEA, CA 19-9, or both should be used with caution for tumour response evaluation to chemotherapy in addition to CT in metastatic colorectal carcinoma.

RESUMO

INTRODUCTION: Digestive localisation of sarcoidosis is rare. OBSERVATION: A 35 year-old man presented with sarcoidosis revealed by a mediastinal hilum lymphadenopathy 13 years earlier. Epigastric pain led to oeso-gastroduodenal fibroscopy and biopsies, showing inflammatory mucosa and numerous giant-cell epithelioid granulomas, without concomitant necrosis or fibrosis. COMMENTS: The clinical manifestations and endoscopic profile of gastric localisations of sarcoidosis are not specific. Diagnosis relies on several elements: presence of epithelioid granulomas without necrosis, history of sarcoidosis or the simultaneous existence of other localisations, evocative biological signs and the absence of elements evoking any other diagnosis. Treatment relies on corticosteroid therapy and sometimes requires endoscopic or surgical management.

RESUMO

PURPOSE: Chronic radiation proctitis, a well described complication of pelvic radiation therapy, can result in severe bleeding that is refractory to conventional treatment. Argon plasma coagulation is an effective treatment for hemorrhagic lesions of the gastrointestinal tract. The aim of this study was to assess the efficacy and safety of argon plasma coagulation in the management of severe radiation proctitis resistant to medical treatment. METHODS: Eleven patients (10 males) aged between 54 and 86 years (mean +/- standard error of the mean, 73 +/- 3 years), with chronic radiation proctitis after radiotherapy for prostate (n = 9), uterine (n = 1) or rectal (n = 1) cancer were enrolled in this prospective study. Traditional therapies had failed including mainly topical steroids, 5-aminosalicylic acid and sometimes sucralfate. All patients had active bleeding from diffuse telangiectasias responsible for chronic anemia and seven of them required blood transfusions. The mean duration of the sessions was 20 minutes and one to five sessions (mean, 3.2 +/- 0.4), usually without anesthesia, were required to stop bleeding. Mean follow-up time was 19 +/- 2 (range, 7-30) months. RESULTS: Rectal bleeding disappeared in nine patients and was greatly reduced in two. All the patients were free of transfusions during the mean follow-up of 19 months. The mean hemoglobin level was 7.7 +/- 2.8 g/dl at the first session and increased significantly (P = 0.003) to 11.5 +/- 2.6 g/dl after treatment. In two patients, a rectal stenosis appeared 7 and 11 months after the first session. CONCLUSION: Argon plasma coagulation is a simple, inexpensive and effective treatment for severe refractory radiation proctitis with telangiectasias. Follow-up supervision is in progress to evaluate long term benefits and the risk of rectal stenosis.

RESUMO

BACKGROUND: Idiopathic portal hypertension is a rare clinical syndrome which may be associated with a spectrum of histological lesions, including nodular regenerative hyperplasia and incomplete septal cirrhosis. Here, we report eight adult patients with idiopathic portal hypertension who experienced an unusually severe clinical evolution characterized by the development of progressive hepatic failure requiring orthotopic liver transplantation. Our aims are: (a) to stress the distinctive clinical presentation of these patients, (b) to describe their biological and histopathological features, and (c) to evaluate the results of orthotopic liver transplantation in this rare indication. METHODS: Complete clinical charts and histological data were available in all patients. All patients were male. Their age at diagnosis ranged from 17 to 59 years. Complications of portal hypertension revealed the disease in all cases. Medical treatment was performed in all patients and portosystemic shunt in three. RESULTS: The development of progressive hepatic failure led to the indication of liver transplantation after a delay ranging from 3 to 10 years. Explanted livers showed pure nodular regenerative hyperplasia in three patients and incomplete septal cirrhosis in five. Recovery was uneventful. All patients are alive, without recurrence of the disease. CONCLUSIONS: This report points to the existence of severe cases of idiopathic portal hypertension occurring without underlying or associated systemic disease and characterized by a poor clinical course and requiring liver transplantation.

RESUMO

OBJECTIVES: The aim of this study was to evaluate the feasibility, toxicity, and efficacy of a curative combination of chemo-radiotherapy with high-dose-rate brachytherapy (HDRB) in patients with non metastatic esophageal cancer. PATIENTS AND METHODS: Fifty-two patients with esophageal carcinoma were treated with > 50 Gy external irradiation, concomitant chemotherapy (5FU-CDDP) followed by HDRB delivering 12.5 Gy (6-20) as a boost. Twelve patients were stage I, 20 stage IIa, 5 stage IIb, and 13 stage III, 1 Tis, 1 stage N unknown. Surgery was not indicated for medical reasons. RESULTS: The response rate was 96%, with complete response rate 85%. The 1-, 3-, 5-year overall survival rates were 78%, 33%, and 22% respectively. A local failure occurred in 32%, and distant metastasis in 16%. Severe (grade 3, 4) acute toxicity occurred in 6 cases, severe late toxicity in 2 cases and there was 1 toxic death. Tumoral length > or = 5 cm and stage IIa, IIb and III versus stage 1 indicated poor prognosis. CONCLUSION: This regimen is feasible and well tolerated. The 5-year overall survival is 22%, but the local failure rate is still very high. These results are encouraging and will be prospectively evaluated with currently ongoing randomized trial.

RESUMO

Gammacarboxyglutamic acid (gla) is a non essential amino acid synthesized in presence of vitamin K, predominantly found in coagulation and bone proteins. In 14 cases of deep vein thrombosis and in 11 cases of disseminated intravascular coagulation, compared to 19 normal subjects and 9 patients hospitalized for leg pain, free plasma gla levels were found significantly elevated (respectively 372 +/- 244 and 559 +/- 361 versus 146 +/- 34 and 120 +/- 40 pmol/mL). In six paired plasma and serum, gla levels were similar. These results suggest an involvement of blood coagulation in gla generation with need of a catabolism of the activated factors. A significant decrease was noticed during vitamin K antagonist therapy and liver disease, both instances in which the synthesis of gla containing coagulation factors is affected. During hepatocellular carcinoma with elevated desgamma carboxyprothrombin, gla was found normal, denying an global impairement of the vitamin K metabolism.

RESUMO

This double-blind cross-over study was carried out in 16 patients (16 arteriographies). In order to evaluate the intra-arterial infusion of buflomédil during arteriographies with lipiodol for the positive and staging diagnosis of hepatocarcinoma and in arteriolar chemoembolisation during a second period for the treatment of the known hepatocarcinoma. The intra-arterial effect of buflomédil was studied by measuring the up-stream reflux of the catheter during the infusion, the number of lesions and the suppression of arterial spasms. The buflomédil infusion decreased the upstream reflux, the number of spasms in the hepatic artery observed during the reiterated chemoembolisations. On the other hand, the visualisation of the limits and number of nodular lesions was impaired and under-estimated by excessive impregnation of the tissue by the contrast medium. In one case buflomédil permitted to visualize an arterio-portal fistula unrecognized under placebo. The clinical tolerance was good with no side-effects. The systolic and diastolic blood pressure did not change versus placebo. The buflomédil infusion during chemoembolisation makes the technique potentially safer by decreasing the up-stream reflux and spasms of hepatic arteries.

RESUMO

The authors report the case of a 51-year-old woman who was hospitalized for severe acute colitis. Sub-total colectomy was performed, due to clinical deterioration and resistance to treatment. The examination of the surgery specimen revealed a herpes-virus type 2 as the responsible pathogen agent. Complementary aciclovir treatment cured the patient.

RESUMO

Azathioprine hepatotoxicity has been described mainly in renal transplant recipients. Most reported cases are related to lesions of the venous system of the liver: peliosis hepatis, veno-occlusive disease of the liver, perisinusoidal fibrosis, and nodular regenerative hyperplasia of the liver. The most common clinical manifestation of these hepatic vascular lesions is portal hypertension. We present a case of nodular regenerative hyperplasia and perivenous fibrosis in a patient receiving azathioprine for multiple sclerosis. Histological abnormalities were similar to those described in renal transplant patients, and azathioprine was the only potential hepatotoxic agent present.

RESUMO

The results of prospectively determined scoring system for the diagnosis of appendicitis (sex, age, duration of symptoms, contracture, hyperleucocytosis) are reported. Between 1984 and 1989, 492 patients with suspected appendicitis were examined. Among the 208 operated patients, 169 had acute appendicitis (81.25 percent). Diagnosis of the abdominal pain was established in one of 3 patients without appendicitis (105/323; non operated patients or operated patients with normal appendix). Eighty-five percent of the non operated patients and 92 percent of the patients operated on with normal appendix have been followed (mean follow-up 26 months). Ten percent of the non operated patients (24/237) have been operated on during follow up; 13.9 percent of the operated patients with normal appendix (5/36) and 22.8 percent of the non operated patients (54/237) still complained of persistent right lower quadrant pain (no significative difference). In conclusion, a clinical scoring system is of help in suspected acute appendicitis. This attitude requires the cooperation of the general practitioner and must be well explained to families of patients.

RESUMO

Adenocarcinoma of the stomach occurred in six of 425 consecutive patients with esophageal squamous cell cancer. In two cases, the gastric cancer, which was recognized at 17 and 29 months, respectively, after the nonsurgical treatment of the esophageal tumor, was treated by surgical resection. In three cases, the tumors which were diagnosed simultaneously, were treated by surgery (one case) resection of the gastric tumor and nonsurgical therapy for the esophageal tumor (one case), and nonsurgical therapy for both tumors (one case). In one case, a gastric cancer was resected 6 years before diagnosis of an esophageal tumor and a second cancer in the gastric stump. A nonsurgical protocol was then adopted for both tumors. The association of these two cancers raises questions concerning their epidemiology, diagnosis, prognosis, and management. There is room for nonsurgical multimodality protocols and, in association with surgery, survival was prolonged for more than 1 year in five of six patients.

RESUMO

One hundred and forty-one patients (100 males, mean age 56.8 +/- 11 years) with a previous bleeding episode from ruptured esophageal varices were followed prospectively after obliteration of varices by elective endoscopic sclerotherapy. Eighty two p. 100 had alcoholic cirrhosis, 30 p. 100 were Child Pugh class A, 60 p. 100 B, 10 p. 100 C. Median follow up period was 16 months. Endoscopic control was carried out on a three month schedule. Compliance was perfect in 81 p. 100 of cases. Recurrent varices developed in 58 patients within a mean (+/- SD) delay of 6.8 +/- 4.7 months. One to 2 sclerotherapy sessions were required to obliterate recurrent varices without serious complications. The frequency of variceal recurrence was significantly lower (p less than 0.001) in case of alcohol with arawal. Five patients (3.5 p. 100) presented a recurrence of variceal bleeding which was fatal in 3 cases. During the follow up period, there were 25 deaths (17.7 p. 100). Survival was significantly correlated to the Child Pugh class (p less than 0.02) and significantly increased in the group of patients who adhered to the protocol (p greater than 0.05). These results suggest that after obliteration of varices patients should be submitted to a trimestrial endoscopic control during the first year, the subsequent schedule being determined by the recurrence of varices during the first year. Endoscopic and clinical follow up of patients, which facilitates alcohol with arawal, could have a favorable effect on the course of hepatic disease.

RESUMO

The treatment of villous rectal tumors with the Nd: YAG laser is characterized by its great effectiveness (almost 90% of complete eradication in our series of 100 cases), and by its great tolerance. It may be applied to all patients regardless of their condition. In case of running villous tumors, complete destruction is more difficult to obtain and the laser method must be weighed against the risks and advantages of radical surgery. The problems raised by frequent foci of adenocarcinoma, which characterize large villous lesions, is minimized by a strict therapeutic protocol: in fact, the foci are superficial in the majority of the cases and they do not decrease the percentage of complete destruction; in other cases, it is possible, by repeated histological controls, in case of persisting positive biopsies, to modify, in time, the choice of treatment.
