Undifferentiated nasopharyngeal carcinoma: pattern of failure--experience at the Johannesburg Hospital (1989-1994).
The records of 18 African patients with recurrent undifferentiated nasopharyngeal carcinoma (UDNPC) were reviewed. The skeletal system was the most common site of distant metastases. The pattern of skeletal involvement conformed to the general pattern, with the spine and pelvis being the most common sites. We conclude that metastatic UDNPC seen in Southern Africa resembles its North African and Southeast Asian counterparts.
