A community-based case-control study was carried out to assess multiple risk factors and familial aggregation of nasopharyngeal carcinoma (NPC). All of the 347 pathologically-confirmed NPC new cases were serially recruited from the National Taiwan University Hospital, and healthy community controls one-to-one matched with cases on age, sex and residence(More)
In order to assess the association between human leukocyte antigens (HLA) and nasopharyngeal carcinoma (NPC), a total of 10 familial and 10 sporadic NPC patients and 171 unrelated healthy controls were studied. HLA typing was performed using commercial trays which defined 30 specificities of HLA-A, B and C loci and 10 specificities of HLA-D locus according(More)
To analyze the characteristics and prognostic factors of penile cancer in Taiwanese, we retrospectively reviewed the clinical data of patients with a diagnosis of penile cancer treated during a 20-year period (1977-1996) at National Taiwan University Hospital (NTUH). Of 71 patients treated for penile cancer during the study period, 17 were referred from(More)
The survival rates following treatment of 1,555 consecutive, previously untreated patients with nasopharyngeal carcinoma were studied. A 92.5% follow-up rate in 11 years is reported. Overall survival rates were 82.7% at one year, 67.4% at two years, 47.8% at five years, and 39.8% at ten years. Computer analysis revealed various factors influencing the(More)
Binding isotherms of ethidium to the superhelical DNA from phage PM2, and to PM2 DNA containing -1 single-chain scission per molecule, have been determined at six temperatures from 2.5 to 50 degrees, in 3M CsCl-0.01 M Na3EDTA. Spectrophotometric measurements in both the visible and ultraviolet (uv) regions were used to obtain the binding isotherms. The(More)
The different responses of plasma aldosterone to ACTH and angiotensin II in aldosterone-producing adenoma (APA) is thought to be due to the various cellular compositions of the tumors. To investigate whether the dopaminergic regulation of aldosterone in APA is also dependent on the cellular types, we studied the effects of metoclopramide on plasma(More)
In 35 patients with nasopharyngeal carcinoma that occupied the fossa of Rosenmüller, the relationship of the tumor, assessed by computed tomographic scans, to otitis media with effusion and ventilatory function of the eustachian tube was examined. Incidence of otitis media with effusion was low when the tumor was limited to the fossa of Rosenmüller (stage(More)
BACKGROUND Laryngeal sarcoma is a rare disease entity. In review of the literature, chondrosarcoma is the most common sarcoma, followed by fibrosarcoma. Osteosarcoma is very rare; there are only seven cases reported in the literature. Postirradiation sarcoma is a late complication of radiotherapy. Osteosarcoma is the most common type in this group.
