BACKGROUND Carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC-Ag), and CYFRA 21-1 are the most useful markers for non-small cell lung cancer (NSCLC), but neuron-specific enolase (NSE) is a tumor maker of choice for SCLC. The determination of NSE in NSCLC could allow selection of patients with neuroendocrine features. NSCLC patients whose(More)
The records of 690 Stage I and II breast cancer patients (31% of them with transfusions), who underwent mastectomy with axillary dissection were examined whether perioperative blood transfusion might be detrimental to survival. The overall 5- and 10-year survival rates for 477 patients who had not received transfusions were 75% and 63% respectively,(More)
BACKGROUND Improvements in local control are required when using preoperative chemoradiation for cT4 or advanced cT3 rectal cancer. There is therefore a need to explore more effective schedules. PATIENTS AND METHODS Patients with fixed cT3 or cT4 cancer were randomized either to 5 × 5 Gy and three cycles of FOLFOX4 (group A) or to 50.4 Gy in 28 fractions(More)
The analysis included 78 patients (42 men and 36 women) aged 48 to 67 years treated with cytostatics because of a neoplastic disease. In all the patients examined was evaluated the influence of the chemotherapy carried out on the glutathione peroxidase (GPx) and glutathione reductase (GR) activities. It was confirmed that the effect of the action on the(More)
Retrorectal tumors (RRT) constitute an anatomical grouping of various tumors of different nature, both benign and malignant. The diversity of their presentation, surgical management, and prognosis are illustrated by five clinical cases. A simple categorization would distinguish vestigial tumors (whether cystic or solid), congenital nonvestigial tumors such(More)
The cases of 4 patients with primary skin melanoma, who underwent resection of the small intestine due to the intestinal metastases, are presented. Two patients died as a result of metastases after intestinal resection; the other two have been alive for a year and 10 years without any symptoms of the disease. The presence of the melanoma metastases to the(More)
Ninety-three patients with pulmonary metastases (PM) were operated on between 1983 and 1997. Surgical complications occurred in 8 (9%) of patients. Two (3%) of patients died in hospital, 7 were operated on again due to further PM. An average survival after lung metastasis surgery was 40 months, median 22 months. 44% and 35% of patients survived respectively(More)
