Molecularly targeted cancer therapies, such as small-molecule kinase inhibitors and monoclonal antibodies, constitute a rapidly growing and an important part of the oncology armamentarium. Unlike conventional (cytotoxic) chemotherapeutics, targeted therapies were designed to disrupt cancer cell pathogenesis at specific biological points essential for the(More)
OBJECTIVE Myeloablative conditioning regimens given prior to hematopoietic stem cell transplantation (HSCT) frequently cause permanent sterility in men. In patients with sickle cell disease (SCD) we use a nonmyeloablative regimen with sirolimus, alemtuzumab, and low-dose total-body irradiation (300 centigrays) with gonadal shielding preceding allogeneic(More)
With the objective of discovering novel tumor-associated antigens of the cancer/testis type, we compared the transcriptional profiles of renal cell carcinoma (RCC) and non-tumorous kidney and further screened for genes expressed in RCC and testis, but not other normal tissues. In a first step, a representational difference analysis library consisting of(More)
We report a case of kappa light chain deposition disease (LCDD) associated with multiple myeloma in a patient presenting with acute renal failure, 2+ proteinuria and hypercalcemia. Serum protein electrophoresis showed an M-spike at 0.1 g/dL. 24-h urine protein electrophoresis showed Bence-Jones proteinuria of 3.8 g. Serum-free light chain assay found excess(More)
Epithelial ovarian cancer comprises ∼85% of all ovarian cancer cases. Despite acceptance regarding the influence of reproductive hormones on ovarian cancer risk and considerable advances in the understanding of epithelial ovarian carcinogenesis on a molecular level, complete understanding of the biologic processes underlying malignant transformation of(More)
We report the case of a 79-year-old Caucasian man, who developed numerous pruritic seborrheic keratoses on his chest and back within one year. An underlying malignant disease was suspected. Upper and lower endoscopies were performed and the patient was diagnosed with adenocarcinoma of the ascending colon. We discuss the clinical significance of his(More)
Thymic epithelial tumors (TETs) are comprised of a spectrum of histolog-ically distinct tumors that also exhibit differences at the molecular level (1). Surgery is the mainstay of treatment but locally advanced and metastatic TETs can be inoperable and are associated with worse survival (2). Although multi-agent chemotherapy is associated with objective(More)
The propensity of colon cancer to metastasize to bones is very low compared to prostate, breast or lung cancer. The reason for this is not yet understood, although an explanation for the osteotropism of certain primaries has been offered by the 'seed and soil' concept, suggesting that the bone microenvironment provides a favorable 'soil' for metastasis and(More)
