Third-World Hodgkin's disease at Los Angeles County-University of Southern California Medical Center.

The reported experience with Hodgkin's disease (HD) in the United States has come primarily from large referral centers that attract a predominantly white population of high socioeconomic status (SES). The majority of these patients had the nodular sclerosis (NS) histologic subtype and asymptomatic stage I/II disease. We have reviewed the records of 178 patients with HD seen within the past 17 years at Los Angeles County-University of Southern California Medical Center (LAC/USC), which is a nonreferral, government-operated facility. Our patient population was found to be heterogeneous, with 38% white, 22% black, and 36% Hispanic. Systemic "B" symptoms were noted in 62% of patients at diagnosis, and 63% had advanced disease (stage III or IV). NS pathologic subtype was present in only 52% of the group. Comparison between the races revealed: (1) Hispanics had a higher incidence of lymphocyte depleted subtype and less NS than whites (P less than .06); (2) whites had equal distribution between stages I/II and III/IV; (3) blacks and Hispanics presented more frequently with stage III/IV (P = .10); and (4) extranodal involvement occurred most often in bone in whites, and was equally distributed between liver, lung, and bone in blacks and Hispanics. We conclude that the lower SES, mixed racial population seen at our institution more closely resembles the reports of HD in Third-World countries and is characterized by advanced symptomatic disease. Further, the clinical pathologic characteristics of HD in the United States may vary significantly, depending upon the precise ethnic and socioeconomic status of the patients being served.

Asbestos exposure and lymphomas of the gastrointestinal tract and oral cavity.

An epidemiological case-control study of non-Hodgkin's lymphomas revealed an excess of male patients with large-cell lymphomas primary to the gastrointestinal tract and oral cavity who had evidence of substantial exposure to asbestos. Between 1977 and 1981, 28 men with large-cell lymphomas primary to these sites were interviewed about previous environmental exposure. Pathology slides from 26 of these cases were reviewed by haematopathologists, who confirmed each to be non-Hodgkin's lymphoma of large-cell type. Neighbourhood controls were matched to patients for age, race, and sex. 13 matched pairs were discordant for asbestos exposure, and in 12 of these the exposed individual was a lymphoma patient. 10 patients and 1 control also reported a history of malaria.
