Preoperative concurrent chemotherapy and radiotherapy for local-regional and advanced squamous cell carcinoma of the thoracic oesophagus: preliminary results of a pilot study.

Preliminary experience based on the results of a pilot study on preoperative concurrent continuous i.v. infusion chemotherapy and radiotherapy for squamous cell carcinoma of the oesophagus in eight consecutive patients is presented. Chemotherapy consisted of 5-fluorouracil and cisplatin. Radiotherapy (Co-60) was delivered to a total dose of 3000 cGy. Clinical tolerance was good in four of eight patients, but poor in the remaining four, including three septic deaths. Oesophagectomy was performed in five patients with no postoperative deaths. Postoperative complications (Horner syndrome, hydrothorax, abdominal wound dehiscence) were observed in three cases. The response was categorized as complete (CR), partial (PR) or stable disease (SD), based on a comparison of the initial and immediate preoperative imaging studies and on the presence of tumour degeneration and/or necrosis in pathological examination of operative specimens. CR was observed in 1/8 patients, PR in 4/8 and SD in 3/8. Concurrent preoperative chemo- and radiotherapy may be effective as a neo-adjuvant or remission-inducing modality in the combined treatment of oesophageal carcinoma, however, it may also lead to fatal complications.

Case report. Renal oncocytoma.

In a case of renal oncocytic adenoma, a "spoke-wheel" pattern of pathological vessels was observed at arteriography of the highly vascular tumor. Computed tomograpy revealed a solid mass with attenuation value significantly higher than that of the normal renal tissue.

[Cholangiographic appearance of the intraphepatic bile ducts (author's transl)].

Percutaneous transphepatic cholangiography patterns of intrahepatic bile ducts in 134 patients were analysed. The majority of case material consisted of gallstone disease and complications of its surgery (44 cases) and secondary or primary neoplasms of the liver (40 cases). A satisfactory filling of the peripheral bile ducts was obtained after drainage of bile and with an injection of somewhat increased quantities of contrast medium into the biliary system. PTC was found to be highly effective in detecting space occupying lesions of neoplastic origin i.e. sensitivity-90 percent, specificity-95 percent, predictive value of a positive result-88 percent. PTC patterns of liver cirrhosis with concommitant extraheptic obstruction, chronic cholangitis, congenital ectasia of the bile ducts, liver abscesses are described. Although PTC is aimed primarily at the detection of nature and level of the extraheptic biliary obstruction there is no essential reason for neglecting its possibilities in recognizing intrahepatic disease.
