Injectable gallium (Ga) nitrate, approved in the United States for the treatment of hypercalcemia of malignancy, has been known for more than 2 decades to have immunosuppressive properties. At therapeutic doses, it has few adverse effects, although high-dose infusions may result in severe nephrotoxicity, particularly in patients who are not adequately hydrated, and severe anemia. In animal models, Ga has been shown to have efficacy in the treatment of adjuvant arthritis, type 1 diabetes, experimental autoimmune encephalomyelitis, experimental pulmonary inflammation, cardiac allograft rejection, experimental autoimmune uveitis, endotoxic shock, and systemic lupus erythematosus. Clinical trials have demonstrated efficacy in Paget's disease of bone and activity against some malignancies, including epithelial ovarian carcinoma, non-squamous cell carcinoma of the cervix, bladder cancer, and non-Hodgkin's lymphoma. Other clinical trials underway include studies of sarcoidosis and rheumatoid arthritis. Future studies should be conducted not only in other autoimmune diseases, such as multiple sclerosis, but also in graft-versus-host disease, leprosy, and acquired immunodeficiency syndrome (AIDS).

From March 1991 through 31st December 2007, 2042 patients underwent stem cell transplantation at the Hematology-Oncology and Stem Cell Transplantation Research Center, affiliated to Tehran University of Medical Sciences. These transplantations included 1405 allogeneic stem cell transplantation, 624 autologous stem cell transplantation, and 13 syngeneic stem cell transplantation. Stem cell transplantation was performed for various diseases including acute myelogenous leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, chronic lymphoblastic leukemia, thalassemia major, sickle cell thalassemia, sickle cell disease, multiple myeloma, myelodysplasia, mucopolysaccharidosis, paroxysmal nocturnal hemoglobinuria, non-Hodgkin's lymphoma, Hodgkin's disease, severe aplastic anemia, plasma cell leukemia, Niemann-Pick disease, Fanconi anemia, severe combine immunodeficiency, congenital neutropenia, leukocyte adhesion deficiencies, Chediak-Higashi syndrome, osteopetrosis, histiocytosis X, Hurler syndrome, amyloidosis, systemic sclerosis, breast cancer, Ewing's sarcoma, testicular cancer, germ cell tumors, neuroblastoma, medulloblastoma, renal cell carcinoma, nasopharyngeal carcinoma, ovarian cancer, Wilms' tumor, rhabdomyosarcoma, pancreatoblastoma, and multiple sclerosis. We had 105 cellular therapies for postmyocardial infarction, multiple sclerosis, cirrhosis, head of femur necrosis, and renal cell carcinoma. About 30 patients were retransplanted in this center. About 74.9% of the patients (1530 of 2042) remained alive between one to 168 months after stem cell transplantation. Nearly 25.1% (512 of 2042) of our patients died after stem cell transplantation. The causes of deaths were relapse, infections, hemorrhagic cystitis, graft versus host disease, and others.

Hematopoietic SCT (HSCT) is a well-recognized therapeutic procedure to prolong life and cure patients with life-threatening hematological malignancies; however, the risk of developing secondary carcinoma may increase in long-term survivors. The objective of this study was to determine the incidence and risk factors for secondary squamous carcinoma after HSCT. Between 1984 and 2004, 170 allogeneic HSCT recipients aged >15 years, who had survived for >5 years were enrolled. Demographic data and the characteristics of secondary carcinoma were collected and analyzed for the determination of the incidence and risk of developing secondary carcinoma. Eight patients developed secondary carcinoma, including five oral squamous cell carcinomas, one esophageal, one gastric and one ovarian carcinoma, but no cutaneous carcinomas were detected at a median follow-up of 14.1 years (range, 5.1-23.3 years) after HSCT. The accrual 10-year cumulative incidence of secondary carcinoma was 2.89%. In univariate and multivariate analyses, chronic GVHD and age >40 years at the time of HSCT were both significant risk factors independently associated with the development of secondary carcinoma. Thus, the occurrence of secondary carcinoma is one of the late complications in patients undergoing HSCT. Oral squamous cell carcinoma was more common in our patients after HSCT, indicating the need for lifelong surveillance of the oral cavity. Moreover, because of the relatively long latency in developing secondary carcinoma, extended follow-up is required for a thorough understanding of the incidence and characteristics of secondary carcinoma after HSCT.
