The exact risk of second cancer (S.C.) following treatment of testicular seminoma is not well determined in most series. At our institution, 122 patients with pure seminoma were treated by orchidectomy followed by radiation therapy from 1951 to 1986. Six were lost to follow-up. For the 116 remaining patients, the overall 5-, 10-, 15- and 20-year survival probability was 95%, 90%, 87%, and 84%, respectively. Eleven patients developed 12 second cancers, with a cumulative risk of 7%, 16%, and 16% at 10, 15, and 20 years, respectively. Overall, the risk of second cancer was increased (O/E = 1.97, p = 0.023). There were 3 controlateral seminoma (O/E = 50, p = 0.001), 2 transitional carcinoma of the bladder (O/E = 6.9, p = 0.035), 2 non-Hodgkin's lymphoma (N.S.), 1 acute myeloblastic leukemia, 1 chronic lymphocytic leukemia, 1 intracranial dysgerminoma, 1 rectal and 1 lung adenocarcinoma. Four tumors developed within the previously irradiated field (O/E = 2.2, N.S.). Excluding second seminoma, the overall risk of second cancer was not significant (O/E = 1.33). Five of the 11 patients with second cancer are currently alive without recurrent cancer. We conclude that patients treated for seminoma have an increased risk of second cancer but the overall prognosis remains excellent. The potential factors responsible for second cancer, including irradiation, are discussed.

Magnetic resonance imaging (MRI) is able to detect the increase of adipocytes in the hematopoietic bone marrow that occurs as a consequence of radiotherapy and is indicative of the loss of myeloid tissue. By monitoring this process, it is also possible to determine the recovery of the bone marrow. The amount of viable hematopoietic tissue plays a fundamental role in determining whether the patient is able to undergo further antineoplastic therapy, particularly chemotherapy. We examined 35 patients who had been treated with radiotherapy for Hodgkin's lymphoma (12), uterine cervix carcinoma (nine), ovarian dysgerminoma (six), testicular seminoma (four), and non-Hodgkin's lymphoma (four). We observed that radiation-induced modifications of the MRI pattern in the bone marrow are tightly linked to two parameters; the administered radiation dose and the length of time passed after the treatment. Bone marrow recovery was observed only when patients were treated with doses lower than 50 Gy. The earlier radiation-induced modifications of the bone marrow MRI pattern occurred 6 to 12 months after irradiation, and they were most evident 5 to 6 years after the treatment. From 2 to 9 years after radiotherapy, we observed partial recovery. Complete recovery, when it occurred, was observed only 10 to 23 years after the treatment. Our results indicate that MRI studies are likely to be useful in the assessment of radiation-induced injuries.

Kaposi's sarcoma and non-Hodgkin's lymphoma were among the earliest recognized manifestations of the acquired immunodeficiency syndrome (AIDS) epidemic. Excluding these two tumors, the overall risk of all other cancers in human immunodeficiency virus (HIV)-infected individuals is similar to that of the general population. However, varying levels of evidence link several additional neoplasms to HIV infection. The evidence is strongest for an association with Hodgkin's disease, with lower relative and absolute risks than for non-Hodgkin's lymphoma. Anogenital intraepithelial neoplasia also appears to be HIV associated, but increases of invasive disease are still uncertain for both cervical and anal cancers. Various studies have suggested associations with testicular seminoma, multiple myeloma, oral cancer, and melanoma, but the data are inconsistent. Leiomyosarcoma and benign leiomyomas have increased in incidence in HIV-infected children but are unusual in HIV-infected adults. Conjunctival carcinoma is seen in HIV-infected individuals in sub-Saharan Africa but it is uncommon in Western countries. Most other cancers do not seem to have increased incidences in HIV infection. The etiologic mechanisms of HIV-related cancer likely differ among these diverse cancers and do not globally increase cancer risk.

Patients with HIV infection are at increased risk for developing Kaposi's sarcoma, non-Hodgkin's lymphoma, and several other cancers. The relative risks for the most common epithelial cancers in the general population--lung, breast, colon/rectum, stomach, liver, and prostate--are not increased substantially in people with AIDS, however. Accumulating data suggest that HIV-infected patients also are at increased risk for developing Hodgkin's lymphoma, cervical carcinoma in situ (CIS), other anogenital neoplasms (invasive cancer and CIS), leiomyosarcoma, and conjunctival squamous cell carcinoma. There is inconclusive evidence, however, with regard to HIV infection being associated with invasive cervical cancer, testicular seminoma, or hepatocellular carcinoma. Notably, other viral infections have been implicated in the etiology of many of these conditions. The introduction of highly active antiretroviral therapy (HAART) has decreased the incidence of AIDS-associated cancers in Western countries, but less than 1% of AIDS patients are receiving HAART in the HIV epicenter of sub-Saharan Africa. Further therapeutic advances that extend survival with HIV infection with varying reconstitution of immune competence may lead to additional alterations in cancer risk.
