Abstract

Between September, 1969, and December, 1978, 290 patients received 325 cadaveric renal allografts; 11 others transplanted elsewhere were also observed. Cancers developed in 28 patients (9.3%); 26 of these (93%) had skin cancers. The incidence of skin cancer increased by 5% annually after the first year of graft function, to a cumulative 44% in those surviving 9 years with functioning grafts. This represents an incidence of 4,356/100,000 person years of post-transplant risk--20.6 times the annual incidence of skin cancer in the general population of Southern Queensland. Half of the patients had multiple tumors when the first skin cancer was diagnosed, after a mean latent interval of 34 months. A total of 138 skin cancers occurred in 26 patients (average, 5.3 per patient), with a maximum of 19 in one individual. The ratio of basal to squamous cell carcinoma was reversed from 4:1, in the general population, to 1:1.7. Conventional surgical excision gave satisfactory results, with the one local recurrence being controlled by reexcision. Two patients (7%) died of melanoma and metastatic squamous cell carcinoma, respectively, whereas two of the other four patients who died from cancer had coincidental skin cancer. The two skin cancer ...Continue Reading

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
