Uterine fibroids are benign solid tumors that are present in the majority of women. While often asymptomatic, fibroids can result in abnormal uterine bleeding, pelvic pressure, pain, subfertility, dyspareunia and other symptoms. Submucous and intramural fibroids are most associated with heavy menstrual bleeding; subserosal fibroids are more often innocuous unless sufficiently large so as to con...

PURPOSE Expression of tumor suppressor gene, MASPIN, is associated with inhibition of tumor cell invasion and metastasis. Loss of or decreased expression of Maspin is found frequently in breast and prostate cancer cells. The objective of this study is to investigate Maspin expression in prostate tumor specimens and explore the mechanisms of hormonal regulation of Maspin expression in prostate t...

To develop a long-circulating theragnostics, meaning therapeutics and diagnostics for MR-guided HIFU ablation, we designed and prepared Gd-C(5)F(12)-phospholipid nanobubbles (PLNs) 30-100 nm in diameter. The biochemical and physical characterization of Gd-C(5)F(12)-PLNs were performed. Since Gd-C(5)F(12)-PLN-50 (Φ = 50 nm) and Gd-C(5)F(12)-PLN-100 (Φ = 100 nm) enhanced the hyperthermal effect o...

Navigated surgery is becoming widely used in applications such as neurosurgery and orthopedics, however it is still in the research phase for soft organs such as the liver. This is mainly because of the organ’s deformability which leads to substantial intraoperative anatomical changes. Particularly in minimally invasive interventions, where the surgeon has no direct access to the organ, image g...

The indolocarbazole analogue CEP-751 is a potent and selective tyrosine kinase inhibitor of the neurotrophin-specific trk receptors that has demonstrated antitumor activity in nine different models of prostate cancer growth in vivo. In the slow-growing, androgen-sensitive Dunning H prostate cancers, which express trk receptors, CEP-751 induced transient regressions independent of effects on cel...

Hepatocellular carcinoma (HCC) is the 3 leading cause of cancer-related death worldwide, and the incidence of HCC is rising in the United States. Patients with cirrhosis of the liver and viral hepatitis are at the highest risk of developing HCC. Radiofrequency ablation has become an accepted first-line treatment for small HCC because of its similar outcomes when compared with surgical resection...

PURPOSE To retrospectively evaluate long-term survival outcomes of radiofrequency (RF) ablation of colorectal lung metastases and evaluate factors associated with improved survival. MATERIALS AND METHODS Eighty-four patients (46 male and 38 female; median age, 65 y) with 172 colorectal lung metastases (median size, 1.2 cm) underwent 113 RF ablation sessions. Thirteen patients had viable extra...

Over the last few years, percutaneous radiofrequency (RF) ablation has been successfully established as a viable treatment modality for small peripheral renal cell carcinoma (RCC). This technique is limited by central tumor location and tumor size. We report the interventional management of a 5.3 cm mixed RCC with central and exophytic parts by combining the RF ablation with embolization, taggi...

The reported complete response rate after single session of chemoembolization for small hepatocellular carcinomas ranged from 75% to 80% on mRECIST evaluation of imaging studies. However, considerable proportion of tumor nodules with complete initial response after chemoembolization show local tumor progression during long-term follow-up. The cumulative 5-year local tumor progression rate of ch...
