Gonadal germ cell tumors are extremely rare among minorities. The recent Surveillance Epidemiology and End Results program for the years 1973 to 1982 revealed that 90.4 percent of cases of testicular germ cell cancers occurred in whites, 2.1 percent in blacks, 6.2 percent in Hispanics, and 1.3 percent in the category of others which included Japanese, Chinese, and patients of unspecified ethnicity. The peak incidence of testicular cancer for adult whites was more than twice that of blacks and Hispanics. buy yasmin online
The precise racial distribution for mediastinal germ cell cancer is unknown, but there is much circumstantial evidence that suggests there may be a higher incidence of mediastinal germ cell tumors among patients who are members of minority groups relative to the incidence of testicular cancer in these groups. In the recent study of patients with advanced germ cell cancer conducted at Indiana University along with the Southeastern and Southwestern Oncology Groups, 151 eligible patients were reviewed. Of these patients, 45 had extragonadal germ cell tumors (23 mediastinal, 21 retroperitoneal, one other). Seven of these patients (five mediastinal and two retroperitoneal) were from members of racial minorities (two Asian-American, two African-American, two Hispanic, one American Indian).
