Purpose: Treatment of lymphomas with combination chemotherapy with or without radiation therapy (XRT) can result in long-term or permanent azoospermia.
Patients And Methods: Semen analyses of lymphoma patients were performed before, during, and after treatment with cyclophosphamide, doxorubicin, vincristine, prednisone, and bleomycin (CHOP-Bleo) chemotherapy. Some of the patients also received other drugs or radiation therapy.
Results: Although no patients were azoospermic before treatment, all were rendered azoospermic during treatment. Following the completion of treatment, the fraction of patients whose sperm counts recovered increased gradually over 5 years and plateaued by 7 years, with two thirds of the men achieving normospermic levels. Scattered gonadal radiation dose and cumulative cyclophosphamide dose were found to be independently significant determinants of recovery: the fraction of patients whose sperm counts recovered to 10 x 10(6)/mL were 83%, 47%, and 20% for those who received less than 9.5 g/m2 of cyclophosphamide, greater than 9.5 g/m2 of cyclophosphamide, and pelvic XRT, respectively. The inclusion of additional drugs and interferon alfa did not significantly affect the long-term recovery of spermatogenesis.
Conclusion: Pelvic XRT and cumulative cyclophosphamide dosages greater than 9.5 g/m2 are associated with a high risk of permanent sterility in lymphoma patients treated with the CHOP-Bleo regimen.

The benefit of adjuvant radiation therapy (RT) in adrenocortical carcinoma (ACC) is not well characterized for those who undergo initial R0 surgical resection. Patients in the NCDB who underwent R0 resection were placed into two cohorts - those who underwent adjuvant RT and those who did not. 388 patients were identified with 51 receiving RT.

Acute alcohol intoxication could cause multiorgan damage, including nervous, digestive, and cardiovascular systems, and in particular, irreversible damage to the brain and liver. Emerging studies have revealed that the endogenous multienzymatic antioxidant defense system (MEAODS) plays a central role in preventing oxidative stress and other toxicological compounds produced by alcohol. However, few available drugs could quickly regulate MEAODS.

Nasopharyngeal carcinoma (NPC) is a malignancy arising from the epithelium of the nasopharynx. Given its late diagnosis, NPC raises serious considerations in Southeast Asia. In addition to resistance to conventional treatment that combines chemotherapy and radiation, NPC has high rates of metastasis and frequent recurrence.

Primary cardiac tumors are a rare disease, with 20% of the cases being malignant. Among them, angiosarcoma is characterized by a short clinical course and poor prognosis, even after surgery, chemotherapy, and radiation therapy. We present a 67-year-old woman diagnosed with a primary malignant tumor (angiosarcoma) infiltrating the right atrial myocardium.

Herpes zoster (HZ) is a viral infection caused by the reactivation of endogenous and latent varicella-zoster virus that remains dormant in the cranial nerve or dorsal root ganglia. HZ occurs in a portion of the general population, with a higher incidence observed in high-risk individuals. Patients with impaired immunity, including human immunodeficiency virus infection, organ transplantation, old age, and cancer-related treatments such as chemotherapy (CT) and radiotherapy (RT) were found more prone to HZ infection.
