    Notes: Abstract We examined the p53 protein and human papilloma virus (HPV) by immunohistochemistry and DNA ploidy by cytofluorometry in paraffin-embedded esophageal carcinoma tissue specimens. Sixty-one patients with superficial esophageal carcinoma were operated on between 1983 and 1991 without any prior treatment. Immunostaining of the anti-p53 protein antibody (CM1) was positive in 32 carcinomas (52%). Patients with p53-positive tumors had a poorer outcome than those with p53-negative tumors (P〈0.05). In addition, patients with p53-positive tumors did not have any characteristic site of relapse. Only 5 of the 61 patients (8.2%) had HPV-positive tumors. One of these 5 carcinomas expressed both p53 protein and HPV. Three patients with HPV-positive tumors which had invaded the submucosal layer died of relapse. A determination of DNA ploidy revealed 30 patients with aneuploid tumors, 13 with polyploid tumors and 18 with diploid tumors. The outcome of the patients with aneuploid tumors was worse than that of the patients with diploid tumor (P〈0.05). p53 protein expression was not associated with DNA ploidy; however, the 16 patients who had both p53-positive and aneuploid tumors had a worse prognosis than patients with p53-negative and aneuploid tumors (P〈0.01). These findings suggest that p53 protein expression in conjunction with DNA ploidy may be a useful indicator in evaluating the prognosis of patients with superficial esophageal carcinoma.

    Description / Table of Contents: Résumé Entre 1985 et 1992, 403 patients ayant eu une résection de leur cancer épidermoïde de l'oesophage thoracique ont eu une évaluation histopathologique corrélée avec la survie. En ce qui concerne la profondeur de l'invasion, huit cas (2%) étaient des pTis, 110 (38%) étaient des pT1, 48 (12%) étaient des pT2, 202 (50%) étaient des pT3, et 35 (8%) étaient des pT4. L'atteinte lymphatique a été détectée chez 299 (74%) patients, une invasion vasculaire dans 200 (49%) des cas, une résurgence intramurale dans 45 (11%) des cas et une atteìnte ganglionnaire chez 232 (58%) des cas. Dans le cas des tumeurs pT1, 4% des cancers de la muqueuse, et 30% des cancers de la sous-muqueuse étaient accompagnées de métastases ganglionnaires. Des tumeurs ayant une invasion plus profonde, les pT3 et les pT4 étaient associées à des métastases ganglionnaires dans 74% et 83% des cas. Les sites des métastases ganglionnaires étaient le médiastin, les chaînes cervicales, et l'abdomen chez, respectivement, 49%, 14% et 41% des cas. Parmi les cas de résection, la mortalité opératoire était de 3.2% et la survie globale à 5 ans étaient de 44.8%. La survie à 5 ans des patients ayant eu une résection à visée curative (R0 et R1) était de 49.5% alors qu'aucun des patients ayant eu une résection palliative (R2) n'étaient en vie à 3 ans. Il n'y avait aucune différence de survie selon la localisation tumorale. Chez les patients réséqués de façon curative, les facteurs pronostiques significatifs étaient la classe pT, l'invasion vasculaire, la métastase lymphatique, et l'invasion intramurale. Le pronostic des patients ayant une métastase ganglionnaire était indépendant de la localisation. Le pronostic des patients ayant un seul ganglion envahi était meilleur que le pronostic des patients ayant six ou plus de ganglions envahis. Le pronostic était moins bon lorsque la métastase ganglionnaire était plus grande que 1 cm, intéressait plus de 2–3 champs différents et lorsqu'elle intéressait la chaîne cervicale en cas de cancer du tiers inférieur de l'oesophage.
    Abstract: Resumen Se analizaron desde el punto de vista histopatológico 403 pacientes, 348 hombres y 55 mujeres, sometidos a resección de carcinoma escamocelular del esófago torácico en el período 1985 a 1992, y se examinaron diversos hallazgos patológicos en relación a sobrevida. En cuanto a profundidad de invasión tumoral, 8(2%) casos fueron Tis, 110(38%) p T1, 48(12%) p T2, 202(50%) p T3 y 35(8%) p T4. Se detectó invasión linfática en 299 casos (74%), invasión de vasos sanguíneos en 200 (49%), metástasis intramurales en 45(11%) y metástasis ganglionares en 232 (58%). Entre los casos en estado p T1, 4% de los carcinomas mucosos y 30% de los submucosos tenían metástasis ganglionares. Los tumores con invasión más profunda exhibieron una mayor incidencia de metástasis ganglionares, 74% en los pacientes en estado pT3 y 83% en los estados pT4. La ubicación de las metástasis ganglionares fue dividida en tres campos: mediastinal, cervical y abdominal, y las ratas de metástasis ganglionares correspondientes fueron 49%, 14%, y 41%. La tasa de mortalidad operatoria fue 3.2% y la tasa global de sobrevida a 5 años fue 44.8%; para los casos con resección curativa (R0 y R1) ésta fue de 49.5%, en tanto que ninguno de los pacientes con resección paliative (R2) sobrevivió más allá de 3 años no se hallaron diferencias significativas en lo relativo a ubicación del cáncer. En los pacientes con resección curativa, los factores pronóstico de importancia significativa determinados por análisis multivariado fueron el estado pT, la invasión vascular, las metástasis ganglionares y las metástasis intramurales. El pronóstico en los pacientes con ganglios positivos no dependió de la ubicación de los ganglios afectados, y los pacientes con sólo un ganglio afectado tuvieron un mejor pronóstico, en tanto que aquellos con 6 o más ganglios afectados tuvieron un pronóstico pobre. En lo relativo a las metástasis ganglionares, otros factores que ensombrecieron el pronóstico fueron los ganglios mayores de 1 cm, metástasis a 2–3 campos y ganglios cervicales positivos cuando el carcinoma primario era del tercio inferior del esófago.
    Notes: Abstract Between 1985 and 1992 a total of 403 patients with resected thoracic esophageal squamous cell carcinoma were evaluated histopathologically, and various pathologic findings related to survival were examined. Concerning depth of tumor invasion, 8 (2%) cases were pTis, 110 (27%) were pT1, 48 (12%) were pT2, 202 (50%) were pT3, and 35 (9%) were pT4. Lymphatic invasion was detected in 299 cases (74%), blood vessel invasion in 200 cases (49%), intramural metastasis in 45 (11%), and lymph node metastasis in 232 (58%). In pT1 carcinoma cases, 4% of mucosal carcinomas and 30% of submucosal carcinomas had lymph node metastasis. Tumors with deeper invasion had a higher incidence of lymph node metastasis: 74% of pT3 carcinomas and 83% of pT4 carcinomas. The sites of lymph node metastasis were divided into mediastinal, cervical, and abdominal fields; and rates of lymph node metastasis were 49%, 14%, and 41%, respectively. In all resected cases, the operative mortality rate was 3.2%, and the overall 5-year survival rate was 44.8%. The 5-year survival rate of patients with curative resection (R0 and R1) was 49.5%, whereas patients with palliative resection (R2) did not survive more than 3 years. There was no significant difference in survival relative to tumor location. In curatively resected cases, the significant prognostic factors by multivariate analysis were pT category, vascular invasion, lymph node metastasis, and intramural metastasis. Prognosis of lymph node-positive cases did not depend on the positive node site. Patients with only one positive node had a better prognosis, and those with six or more positive nodes had a poor prognosis. Concerning lymph node metastasis, other factors that worsened prognosis were a positive node larger than 1 cm, two- to three-field metastasis, and positive cervical nodes in cases of lower-third esophageal carcinoma.

    Notes: Summary In selection for esophageal cancer treatment, it is necessary to evaluate the tumor stage. We have used endoscopic ultrasonography (EUS) for diagnosis of the depth of cancer invasion and the presence of lymph node metastasis since 1983. The EUS image of the normal esophageal wall showed 5 layers. In all, 222 cases of esophageal cancer were examined with EUS, and a radical operation was performed on 139. In 78 of those cases, the scope was passed beyond the cancer site, and total observation was achieved (56%). The extent of cancer invasion was correctly determined in these 78 cases (84%). Thoracic lymph nodes that could be detected by EUS were located in the posterior mediastinum and measured more than 3 mm in diameter. Diagnostic criteria for lymph node metastasis were designated as follows: (1) spherical shape, (2) a distinct border, and (3) heterogenous echo spots within the nodes. The above criteria yielded a sensitivity of 87%, a specificity of 90%, and an overall accuracy of 89% according to the histological examination of the removed lymph nodes.

    Notes: Summary Endoscopic ultrasonography was carried out on 55 patients whose X-ray films or endoscopic examinations indicated the presence of a submucosal tumor. Endoscopic ultrasonography revealed 8 cases of extraluminal compression and 48 cases of submucosal tumors. Histological studies were performed on 29 cases with submucosal tumors. In 28 of the 29 cases (97%) the location of the tumor in the esophageal wall was correctly estimated ultrasonographically, and appropriate treatment was selected. Tumors ranging from 3 to 50 mm in diameter could be measured accurately. This method may be helpful in follow-up studies. Endoscopic ultrasonographic findings, such as characteristics of the tumor border and internal echoes, were studied to predict the histological diagnosis of the tumor. Leiomyoma, cyst, granular cell tumor, lipoma, and intraluminal metastasis of esophageal cancer were all found to have specific ultrasonographic findings indicating the histological nature of the tumor.
