Adjuvant chemotherapy with uracil-tegafur improves survival among patients with completely resected pathological stage I adenocarcinoma of the lung.

Objective: When a new scoring system, ‘E-PASS’, standing for the Estimation of Physiologic Ability and Surgical Stress that predicts the postoperative surgical risk by quantification of the patient’s reserve and surgical stress applied to a population of general thoracic surgery patients, it should be investigated if this system could help us or not. Methods: The comprehensive risk score (CRS) of the E-PASS and the clinical course were evaluated retrospectively in 282 consecutive patients with primary lung cancer (group A), and in 458 patients who underwent elective thoracic operations (group B). Results: The morbidity and mortality rates in both group A and group B increased as the CRS increased. The CRS correlated significantly with the morbidity score, length of stay and cost of hospitalization. Conclusions: E-PASS scoring system may be useful in surgical decision-making and evaluating quality of care in patients who are tolerable for lung resection.

While videothoracoscopic surgery has rapidly become accepted as an effective method of performing minimally invasive surgery, the advantages and feasibility of using this surgical technique for the treatment of neurogenic tumors of the thorax are not yet well defined. Between August 1992 and May 1999, 15 solitary thoracic neurogenic tumors were surgically excised using videothoracoscopic surgery in our hospital. The patients comprised six women and nine men, with a mean age of 38.1 years. The mean tumor size was 3.5 cm, with a range of 1.5-6.5 cm and included 12 schwannomas, 2 ganglioneuromas, and 1 neurofibroma. Among the 15 patients, 4 were treated using videothoracoscopic surgery plus minithoracotomy. The only complication associated with videothoracoscopic surgery was hoarseness which developed in one patient. Our experience indicates that videothoracoscopic surgery is a useful alternative to facilitate the excision of small thoracic neurogenic tumors.

This report describes a case of carcinosarcoma of the duodenum. Carcinosarcoma of the duodenum is a very rare tumor. A 72-year-old man was referred to the hospital because of appetite loss. Endoscopy demonstrated an irregularly depressed lesion (type 3) in the descending portion of the duodenum opposite to the ampulla of Vater. Computed tomography showed a thickened duodenal wall and swelling of the abdominal para-aortic lymph nodes. A biopsy specimen revealed a well-differentiated adenocarcinoma. A diagnosis of duodenal carcinoma was made (cT3, cN1, cM1, cStage IV according to the TNM classification). A subtotal stomach-preserving pancreatoduodenectomy and a lymph node resection were performed. On microscopic examination, adenocarcinoma cells and spindle type sarcoma cells were observed separately in the descending portion of the duodenum opposite to the ampulla of Vater. The adenocarcinoma cells were stained with antibodies against epithelial markers keratin and carcinoembryonic antigen for immunohistochemical analyses. In contrast, the sarcoma cells were stained with antibodies to vimentin and smooth muscle actin. The pathological diagnosis of a true duodenal carcinosarcoma was thus made.
