    Notes: To better comprehend the differences in deoxyribonucleic acid (DNA) content between a primary hepatocellular carcinoma (HCC) and pulmonary metastatic nodules, tissue specimens taken at autopsy of 25 patients who had not received any drugs to treat the malignancy were examined using microspectrophotometry. The DNA distribution patterns were classified into Types I–III, and low (Types I and II) or high (Type III) ploidies, according to DNA distribution. Changes in the DNA content from high to low ploidies, namely DNA ploidy reduction from the primary lesion to pulmonary metastatic lesions, was evident in 9 of the 25 patients (36%), and changes from low to high were noted in 2 of the 25 patients (8%). The remaining 14 (56%) showed no evidence of changes in the DNA ploidy pattern. Reduction of DNA ploidy seen in HCC and its metastatic lesions in the lung may be one of the aspects of clonal evolution or selection mechanisms during the progression of tumor growth and metastasis.

    Description / Table of Contents: Résumé Les auteurs ont étudié les suites opératoires de 50 malades qui avaient subi une résection hépatique en comparant les taux de rétention de l'indocyanine green (ICG) mesurés lors du 3ème jour post-opératoire par rapport à ceux appréciés immédiatement après l'opération. Ce rapport étant l'expression de l'index ICG du parenchyme restant. Le groupe A de 22 malades avec un index restant de moins de 1.0, (qui signifie le taux de rétention de ICG à 15 mm lors du 3ème jour post-opératoire) a montré une amélioration par comparaison aux faits qui ont succédé immédiatement à l'intervention. Un groupe B de 28 malades chez qui l'index au 3ème jour était supérieur à 1.0, indiquant par conséquent une élévation du taux de clarance de l'ICG après résection hépatique, a été individualisé. De sérieuses complications comprenant infection abdominale et hyperbilirubinémie se sont manifestées en post-opératoire respectivement chez 2 (9.1%) du groupe A et 16 (57.1%) du groupe B (p〈0.001). Un malade (4.5%) du groupe A décéda cependant que 9 malades (32.1%) du groupe B moururent pendant l'hospitalisation (p〈0.02). Il ne fut pas constaté de différence significative en ce qui concerne la fonction hépatique préopératoire et les paramètres cliniques. Ces observations suggèrent que l'amélioration du taux de la clairance de l'ICG au 3ème jour post-opératoire par comparaison au taux déterminé immédiatement après l'intervention permet de préjuger des suites post-opératoire après résection hépatique.
    Abstract: Resumen Hemos valorado la evolución postoperatoria de 50 pacientes sometidos a resección hepática, utilizando la relación entre las tasas de retención del verde de indocianina (VIC) medidas en el tercer día postoperatorio y los valores estimados inmediatamente después de la operación. Esta relación fue expresada en forma del indice VIC de remanente hepático. El grupo A incluyó 22 pacientes con un indice de menos de 1.0, lo cual significa que la tasa de retención VIC a los 15 minutos en el tercer día postoperatorio mostró mejoría en comparación con los hallazgos inmediatamente al término de la operación. En el grupo B hubo 28 pacientes cuyos indices en el tercer día postoperatorio fue superior a 1.0, lo cual indica exacerbación de la tasa de depuración de VIC después de la resección hepática. Se presentaron complicaciones postoperatorias graves, incluso sepsis intraabdominal e hiperbilirrubinemia en 2 (9.1%) en el grupo A y 16 (57.1%) en el grupo B (p〈0.001). Murió un paciente (4.5%) en el grupo A contra 9 pacientes (32.1%) que murieron en el grupo B en el curso de la hospitalización (p〈 0.02). No se observaron diferencias significativas en cuanto a las pruebas preoperatorias de función hepática o los parámetros clínicos. Estas observaciones sugieren que la mejoría en la tasa de depuración de VIC en el tercer día postoperatorio, comparada con aquella inmediatamente al término de la operación, es un paramétro de utilidad en la predicción del curso postoperatorio de pacientes hepatectomizados.
    Notes: Abstract We evaluated the postoperative course of 50 patients who underwent hepatic resection, using the ratio of indocyanine green (ICG) retention rates measured on the third postoperative day to values estimated immediately after the operation. This ratio was expressed as the remnant liver ICG index. Group A included 22 patients with a remnamt liver ICG index of less than 1.0, which meant that the ICG retention rate at 15 minutes on the third postoperative day showed improvement, compared to events immediately after the operation. In group B, there were 28 patients whose index on the third postoperative day was over 1.0, thereby indicating exacerbation of the ICG clearance rate after hepatic resection. Serious complications including intraabdominal sepsis and hyperbilirubinemia occurred postoperatively in 2 (9.1%) in group A and 16 (57.1%) in group B (p〈0.001). One patient (4.5%) in group A died, while 9 patients (32.1%) in group B died during hospitalization (p〈 0.02). There were no significant differences with regard to preoperative liver function and clinical parameters. These observations suggest that improvement in the ICG clearance rate on the third postoperative day, compared to that immediately after the operation, is useful to predict the postoperative course of hepatectomized patients.

    Notes: Abstract A 66-year-old man with multiple malignant lesions of the esophagus, as apparently induced by irradiation of 60 Gy of60Co for a mediastinal tumor at the age of 36 y.o., was a poor operative risk because of severe lung disease. This man was treated with a combination of hyperthermia, oral administration of oil Bleomycin-polyacrylate paste and intravenous infusion of cis-Platinum. During 20 administrations of hyperthermia conducted at 42–45°C for 30 min, 600 mg of oil Bleomycin and 200 mg of cis-Platinum, no complications occurred and the heat treatments were completed with no side effects. Repeatedly performed esophagogram and endoscopy showed a complete disappearance of three of the four lesions and a marked regression in the other one. There has been no regrowth or distant spread of the carcinoma up to the present 10 months of follow up. This combination of hyperthermia and chemotherapy may prove to be the optimal strategy for treatment of unresectable esophageal cancer, particularly when radiotherapy is contraindicated.
