The purpose of this study is to test the safety and efficacy of the combination of erlotinib hydrochloride (Tarceva™) and sirolimus (Rapamune™) in the treatment of patients with metastatic kidney cancer.
Despite recent advances metastatic renal cell carcinoma remains an incurable condition. Currently available treatment with high-dose interleukin-2 can lead to complete responses in a small minority of selected patients but is markedly toxic and not broadly available. FDA-approved multikinase inhibitors (sorafenib and sunitinib malate) often cause partial and transient tumor regression. There is no standard treatment metastatic renal cell carcinoma for patients whose disease progressed on multikinase inhibitors. The kinase mammalian target of rapamycin (mTOR) is overstimulated in a subset of renal cell carcinomas and other malignancies and can be blocked by sirolimus leading to growth arrest. Erlotinib hydrochloride is a drug that blocks the function of the epidermal growth factor receptor (EGFR), often over expressed in kidney cancer. Sirolimus and EGFR inhibitors and been safely used in combination. In vitro experiments show that erlotinib enhances the sirolimus induced growth impairment in a panel of renal cell carcinoma cells. In the present study patients with metastatic renal cell carcinoma whose disease progressed on multikinase inhibitors will be treated with the combination of erlotinib hydrochloride (Tarceva™) and sirolimus (Rapamune™). This is a single arm trial with no placebo or drug-based control arm

A 70-year-old man underwent left partial nephrectomy for renal cell carcinoma (pT1aN0M0). One year after the surgery, he presented with hematuria and fatigue. Computed tomography showed a left 8 cm re...
Renal cell carcinoma metastasizing to rectum is very rare, and the unusual metastatic sites should be paid attention to during the follow-up of renal cell carcinoma.
The pancreas is an unusual site for tumor metastasis, accounting for only 2% to 5% of all malignancies affecting the pancreas. The more common metastases affecting the pancreas include renal cell carc...
Non-clear cell renal cell carcinoma includes several histological variants. Tumor biology has significant effect on the duration of the disease. Prognosis at formally similar disease stages may differ...
Renal cell carcinoma accounts for about 3-4% of all malignancies and its incidence is steadily rising. The article presents in short the rationale behind the targeted therapies and provides an update ...
A heterogeneous group of sporadic or hereditary carcinoma derived from cells of the KIDNEYS. There are several subtypes including the clear cells, the papillary, the chromophobe, the collecting duct, the spindle cells (sarcomatoid), or mixed cell-type carcinoma.
An autosomal dominant disorder caused by mutations in a tumor suppressor gene. This syndrome is characterized by abnormal growth of small blood vessels leading to a host of neoplasms. They include HEMANGIOBLASTOMA in the RETINA; CEREBELLUM; and SPINAL CORD; PHEOCHROMOCYTOMA; pancreatic tumors; and renal cell carcinoma (see CARCINOMA, RENAL CELL). Common clinical signs include HYPERTENSION and neurological dysfunctions.
A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.
A rare tumor of the female genital tract, most often the ovary, formerly considered to be derived from mesonephric rests. Two varieties are recognized: (1) clear cell carcinoma, so called because of its histologic resemblance to renal cell carcinoma, and now considered to be of muellerian duct derivation and (2) an embryonal tumor (called also ENDODERMAL SINUS TUMOR and yolk sac tumor), occurring chiefly in children. The latter variety may also arise in the testis. (Dorland, 27th ed)
A carcinoma arising from MERKEL CELLS located in the basal layer of the epidermis and occurring most commonly as a primary neuroendocrine carcinoma of the skin. Merkel cells are tactile cells of neuroectodermal origin and histologically show neurosecretory granules. The skin of the head and neck are a common site of Merkel cell carcinoma, occurring generally in elderly patients. (Holland et al., Cancer Medicine, 3d ed, p1245)
Nephrology - kidney function
Nephrology is a specialty of medicine and pediatrics that concerns itself with the study of normal kidney function, kidney problems, the treatment of kidney problems and renal replacement therapy (dialysis and kidney transplantation). Systemic conditions...
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
