ABSTRACT

The authors describe a case of bilateral pattern dystrophy of the retinal pigment epithelium in a man with Crohn's disease. The patient was examined every 6 months over a follow-up of 30 months. The right eye presented a macroreticular dystrophy while in the left eye a butterfly pattern dystrophy was diagnosed. During the follow-up period the retinal lesion changed; in the right eye the lesion increased in size, while in the left eye the morphology of the lesion passed from the butterfly to Sjögren's type. This report adds a new ocular manifestation of Crohn's disease, emphasizing the importance of the ophthalmological follow-up in the recognition of posterior segment complications associated with this inflammatory bowel disease.

ABSTRACT

The purpose of this study was to determine the prognostic value of the histopathological response to preoperative radio-chemotherapy in patients with locally advanced oesophageal cancer. Among the 57 patients included in this open prospective study, the disease-free cervical of 48 patients who underwent an oesophagectomy was correlated with the histopathological finding. The 5-years probability of disease-free cervical was 22.1%. Cervical of the patients whose tumor had been downstaged to no residual carcinoma or superficial oesophageal carcinoma was significantly shorter than that of patients with superficial oesophageal carcinoma at presentation treated during the same period (35% vs 57%). Univariate analysis could identify 4 prognostic variables after induction therapy: adenocarcinoma, macroscopic, residual tumor, invaded oesophageal stump, and lymph node involvement. After multivariate analysis according to the Cox model, the remaining independent predictors of recurrence were: adenocarcinoma, invaded oesophageal stump, and lymph node involvement.

ABSTRACT

El objetivo de este trabajo es el evaluar la significación pronóstica de la respuesta al tratamiento radioquimioterápico neoadjuvante del cáncer de esófago localmente avanzado. Entre los 57 enfermos incluídos en este estudio propectivo abierto la sobrevida sin recibida pudo ser comparada a la respuesta al tratamiento neoadjuvante en 48 enfermos que fueron sometidos a una esofaguectomía. La respuesta fue analizada sobre la pieza quirúrgica. La probabilidad de sobrevida sin recivida a cinco años fue de 22,1 por ciento. La sobrevida de los enfermos en los que el tumor fue superficial, después del tratamiento neoadjuvante fue del 35 por ciento a cinco años, significativamente inferior a la de los enfermos operados en el curso el mismo período por un tumor inicialmente superficial, que fue del 57 por ciento en cinco años. El análisis monofactorial permitió identificar 4 variables pronósticas significativas: tipo histológico, adenocarcinoma, invasión ganglionar, residuo macroscópico sobre la pieza quirúrgica y borde de sección esofágico invadido. El análisis multifactorial según el modelo de Cox no retuvo más que el tipo histológico glandular, el borde de sección invadido y la presencia de metástasis ganglionar como factor independiente predictivo de una recidiva.

ABSTRACT

OBJECTIVE: To asses the diagnostic accuracy of endoscopic ultrasonography (EUS) for the local and regional staging of esophageal cancer, and its possible alteration resulting from the performance of preoperative chemoradiation. METHODS: Prospective study of 85 consecutive patients with esophageal cancer evaluated by EUS and operated between January 1992 and December 1995. 28 of these patients had received previous induction therapy. In all cases, EUS examination was performed by the same physician not informed about the results of previous morphological explorations. Histopathological analysis of all specimens was performed by the same pathologist, not informed about the results of the EUS. Data were collected by another independent observer. RESULTS: EUS examination resulted in incomplete staging in 8 patients (9.5%) with severe stenosis precluding endoscope passage. The accuracy, specificity and sensibility of EUS in detecting the depth of esophageal involvement (T0-2 vs T3-4) were 82.3%, 78% and 86% respectively, and 72%, 70% and 73% respectively for the lymph node metastasis. The overall accuracy of EUS in identifying the preoperative stage was 67% with a clear-cut alteration when patients had received induction therapy (61% vs 72%). On the other hand, 7(64%) of the 11 patients thought to have a complete response at endosonography had no residual tumor. CONCLUSION: EUS provides precise information for the preoperative identification of locally advanced esophageal tumor, even after induction therapy. The latter alters the diagnostic accuracy of EUS, although complete responders could be identified in two-thirds os cases.

ABSTRACT

Objectivo: Evaluar la presición diagnóstica de la ecoendoscopía para la apreciación de la extensión loco-regional del cáncer del esófago, y su eventual modificación ante un tratamiento neoadyuvante con quimio y radioterapia. Método: Estudio prospectivo sobre 85 pacientes operados por un cáncer del esófago entre enero de 1992 y diciembre de 1995, todos evaluados previamente con ecoendoscopía. Del total de 85 pacientes, 21 recibieron un tratamiento neoadyuvante con quimio y radioterapia. Todos los estudios endoscópicos fueron realizados por el mismo operador, que ignoraba el resultado de otros estudios morfológicos. Todos los exámenes anatomapotológicos de la pieza de resección fueron realizados por el mismo operador que desconocía el resultado de la ecoendoscopía preoperatoria. La confrontación de los datos de la anatomía patológica y de la ecoendoscopía fue realizado por un tercer observador independiente. Resultados: La ecoendoscopía fue incompleta por una estenosis esofágica en 8 casos (9,5 por ciento). La evaluación de la invasión de la pared esofágica tuvo una exactitud del 82,3 por ciento, uma sensibilidad del 78 por ciento y una espeficificidad del 86 por ciento. La evaluación de la extensión ganglionar tuvo una exactitud del 72 por ciento, una sensibilidad del 70 por ciento y una especificidad del 73 por ciento. La evaluación del estadío fue concordante en el 67 por ciento de los casos con un rendimiento totalmente alterado después de realizar tratamiento neoadyuvante con radio-quimioterapia (61 por ciento contra 72 por ciento). Paralelamente, 7 (64 por ciento) de los 11 enfermos que tuvieron una correlación ecoendoscópica perfecta habían tendio una respuesta completa con el tratamiento neoadyuvante. Conclusión: La ecoendoscopías es un método preciso para la evaluación preoperatoria de los tumores del esófago localmente avanzados, asi mismo después de un tratamiento deoadyuvante. Esta última alternativa modifica negativamente el rendimento ddiagnóstico pero de todas formas permite dos veces sobre tres realizar una correlación perfecta en aquellos enfermos que tuvieron una respuesta completa al tratamiento neoadyuvante.

ABSTRACT

OBJECTIVE: The purpose of this study was to determine the prognostic significance of the histopathological response to preoperative radio-chemotherapy in patients with locally advanced oesophageal cancer. METHODS: Among the 57 patients included in this open prospective study, the disease-free survival of 48 patients (8 females 40 males; mean age: 56.6 years +/- 8.4) who underwent an oesophagectomy after induction therapy for oesophageal squamous cell (n = 38) or adenocarcinoma (n = 10) was correlated with the histopathological findings. Chemoradiation included 2 cycles associating continuous 5 FU from D1 to 5 and from D22 to 26, cisplatyl on D1 and D22, 15 Gy/5d from D1 to 5 and from D22 to 26. Histopathological response was assessed on the operative specimens by routine examination of serial thin sections each 5 mm along the full oesophageal length, the resection margins and the lymph node dissection. RESULTS: A wide interindividual variability was seen regarding tissue changes related to induction therapy, with a grading in tumor regression and the possibility of dissociated effects on the various treatment targets: tumor, adenopathy and vessel invasion. The 5-year probability of disease-free survival was 22% for the 48 resected patients. The presence of a complete histopathological response (n = 12) did not preclude metastatic spread in half the cases. Furthermore, it did not result in improved survival when compared to that of non-responder patients. Survival of patients who had a complete or major oesophageal response (n = 29, 35% at 5 years) was significantly lower than that of patients who were operated on during the same period for a superficial oesophageal cancer at presentation (n = 29, 57% at 5 years; P = 0.03). After multivariate analysis according to the Cox model, downstaging of the primary tumor was not identified as an independent predictor of disease-free survival. CONCLUSIONS: Pathologic assessment of tumor regression on the operative specimen provides little prognostic information.

ABSTRACT

OBJECTIVES: To identify the determinants and results on conservative management of oesophageal perforations and ruptures. METHODS: Retrospective clinical review of 34 consecutive patients (mean age: 62 years) treated for cervical (n = 10) or thoracic (n = 24) oesophageal disruption between 1985 and 1996. Causes were: spontaneous rupture (n = 10), instrumental perforation (n = 16), alimentary foreign body (n = 6), and blunt (n = 1) or penetrating trauma (n = 1). The diagnostic delay exceeded 24 hours in 15 cases. RESULTS: A nonoperative management was achieved in 8 patients with no mortality. A conservative surgical treatment was attempted in 23 patients, primary repair in 21 and open drainage in 2, with a 17.4% mortality. Resection (n = 2) or exclusion (n = 1) was performed in 3 patients with no early mortality, but one of them died as result of the subsequent reconstructive operation to restore oesophageal continuity. Overall morbidity was linked to the spontaneous cause of the perforation. Outcome of patients undergoing primary repair was not influenced by the diagnostic delay nor the surrounding sepsis. CONCLUSION: Conservative management should be advocated for the treatment of oesophageal perforations and ruptures, even in case of delayed diagnostiqiagnosis, regardless of the surrounding sepsis and cause of disruption.

ABSTRACT

This report presents the results of a study designed to verify the influence of lens opacities on the visual field indices. Four age-matched groups of subjects were considered: healthy volunteers, glaucomatous patients without lens opacities, cataractous patients without glaucoma and glaucomatous patients with lens opacities. The quantification of lens opacities was performed with the Lens Opacity Meter 701 instrument. The visual field indices were obtained automatically from the G1 program of the Octopus system. The statistical analysis of the results (coefficient of correlation) has shown that only the visual field indices that correspond to uniform and diffuse loss of light sensitivity were influenced by the presence of cataract. On the contrary, the visual field indices that indicate local irregularities of the threshold were not significantly influenced by the presence of lens opacities.
