Contrast-enhanced Ultrasound for Follow-up After Radiofrequency Ablation of Kidney Lesions
Radiofrequency ablation (RFA) is an increasingly popular therapy option for treating small kidney cancer, especially for patients who are not ideal candidates for traditional surgery. Currently, follow-up after this procedure involves the patient having several CT scans (or MRI scans in some cases) over time to monitor for possible cancer recurrence. However, there are risks associated with the radiation exposure from CT scans and other risks, such as adverse events from the contrast media used in these scans. This study will therefore investigate whether a different technique, contrast-enhanced ultrasound (CEUS), can be an effective tool for follow-up monitoring of kidney cancer patients who have undergone RFA by comparing the results of their standard follow-up CT scans (or MRIs if applicable) with the results of CEUS. If CEUS is found to be just as effective as CT scans or MRIs in detecting kidney cancer recurrence, this technique could potentially become the new standard of care for follow-up.

Medical and Biotech [MESH] Definitions
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 malignancy arising in uterine cervical epithelium and confined thereto, representing a continuum of histological changes ranging from well-differentiated CIN 1 (formerly, mild dysplasia) to severe dysplasia/carcinoma in situ, CIN 3. The lesion arises at the squamocolumnar cell junction at the transformation zone of the endocervical canal, with a variable tendency to develop invasive epidermoid carcinoma, a tendency that is enhanced by concomitant human papillomaviral infection. (Segen, Dictionary of Modern Medicine, 1992)
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)
