    Notes: Recent reports demonstrated the presence of Epstein-Barr virus (EBV) in about 10% of gastric carcinoma cases, particularly in Asian populations. We carried out a retrospective assessment of the detection rate of EBV gene products in 59 cases of gastric carcinoma of various histological subtypes. In situ hybridization using non-isotopic EBER and BHLF1 oligoprobes, and immunohistochemistry using antibodies to latent membrane protein 1 (LMP-1) were applied to paraffin-embedded sections. Tumour cells in five out of 59 cases (8.5%) were found to be EBER positive by in situ hybridization, but no staining was observed with LMP-1 antibodies. Four EBER positive cases were lymphoepithelioma-like carcinomas and one case was a well differentiated adenocarcinoma, suggesting a stronger association with the former subtype. Among the four EBER positive lymphoepithelioma-like carcinomas, BHLF1 transcripts were expressed in one case in a few tumour cells, indicating the possible activation of a lytic cycle. In nine cases (including three EBER positive cases) a few scattered EBV-infected lymphocytes were seen in the normal mucosa but we were unable to detect any EBER positive normal epithelial cells. Our results show that, in a French population, the incidence of EBV-associated gastric carcinoma is similar to that in other geographic areas. The clinical implications of these findings, however, remain unclear.

    Description / Table of Contents: Résumé Entre Janvier 1975 et Décembre 1987, 241 patients ayant un cancer rectal ont eu une irradiation pré-opératoire suivie de résection chirurgicale. Vingt cinq MeV ont été délivrés 5 jours par semaine par fractionnement de 7.4 Gy pour un total de 36 Gy. La chirurgie a été considérée comme curatrice chez 195 patients; 57% ont eu une amputation abdominopérinéale. Il a été nécessaire d'arrêter la radiothérapie chez trois patients et quatre patients ont développé ultérieurement une iléite radique. La mortalité postopératoire était de 2.9%. La complication la plus fréquente a été un retard de cicatrisation de la plaie abdominale ou périnéale (dans 18% et 14% des cas). Des complications tardives sont survenues chez 27 patients: 5% ont présenté une occlusion. La survie a été de 18 mois à 13 ans. Une récidive locale a été constatée chez 24 (12%) des 195 patients. La récidive locale est survenue chez 10%, 11.6% et 22.7% selon qu'il s'agissait de tumeurs de stade A, B ou C de Dukes. La survie actuarielle à 5 et à 10 ans après la chirurgie à visée curatrice était de 70 et de 52%. Seul le stade de Dukes influençait la survie.
    Abstract: Resumen Doscientos cuarenta y un pacientes con cáncer rectal fueron tratados con irradiación preoperatoria y resección quirúrgica entre enero de 1975 y diciembre de 1987. La irradiación fue realizada con fotones de 25 MeV por 5 días de la semana mediante dosis fraccionadas de 2.4 grays, hasta una dosis total de 36 grays. La cirugía fue clasificada como curativa en 195 pacientes, de los cuales 57% fueron sometidos a resección abdominoperineal. La irradiación tuvo que ser descontinuada en 3 pacientes, y 4 pacientes ulteriormente desarrollaron ileitis aguda. La tasa mortalidad postoperatoria fue de 2.9%; la complicación postoperatoria más frecuente fue la cicatrización retardada de las heridas abdominal y perineal (18% y 14%). Complicaciones severas tardías se presentaron en 27 pacientes; la incidencia de obstrucción intestinal fue de 5%. El seguimiento de los sobrevivientes osciló entre 18 meses y 13 años. Falla local se presentó en 10%, 11.6% y 22.7% para los tumores Dukes A, B y C respectivamente. Las tasas de sobrevida actuarial a 5 y 10 años después de cirugía clasificada como curativa fueron 70% y 52%. La clasificación de Dukes apareció como el único factor determinante de supervivencia.
    Notes: Abstract From January, 1975 to December, 1987, 241 patients with rectal cancer underwent pre-operative irradiation and surgical resection. The radiation was delivered with 25 MeV photons, 5 days per week by 2.4 grays fractions up to a total dose of 36 grays. Surgery was curative in 195 patients; 57% had abdomino-perinal resection. Irradiation had to be discontinued in 3 patients and 4 patients subsequently developed severe acute ileitis. Postoperative mortality rate was 2.9%. The most frequent postoperative complications were delayed healing of abdominal wounds (18%) and perineal wounds (14%). Severe late complications occurred in 27 (13%) patients. The incidence of intestinal obstruction was 5%. Follow-up survivors ranged from 18 months to 13 years. Local failure occurred in 24 (12%) of the 195 patients. Local failure rates were 10% for Dukes' A tumors, 11.6% for Dukes' B, and 22.7% for Dukes' C tumors. Five and 10 years actuarial survival rates after curative surgery were 70% and 52%. The Dukes' classification was the only factor that influenced survival.

    Notes: Abstract. Diffuse esophageal leiomyomatosis is a rare disorder which may be found in association with leiomyomas in other locations or with other disorders. We report two cases in men, one with associated tracheobronchial involvement, which illustrate the value of imaging in differentiating this entity from other causes of dysphagia and in establishing a diagnosis.
