OBJECTIVE Our goal was to investigate the feasibility of inserting long-term central venous access devices in outpatients using a simple technique that minimizes the risks of complications linked to venipuncture and errors in management. MATERIALS AND METHODS We placed 147 central venous catheters (CVCs) in 134 patients under local anesthesia. No sedation(More)
BACKGROUND This study was designed to determine the feasibility, maximum tolerated dose, and toxicities of intraarterial administration of paclitaxel-albumin nanoparticles in patients with advanced head and neck and recurrent anal canal squamous cell carcinoma. Antitumor activity also was assessed. METHODS Forty-three patients (31 with advanced head and(More)
This letter analyzes the coding efficiency of distributed video coding (DVC) schemes that perform motion-compensated interpolation at the decoder. The decoder has access only to the key frames, when generating the side information for intermediate frames. Therefore, the true motion field necessary for this operation is not directly available, and the motion(More)
PURPOSE To determine the efficacy of chemoembolization (CHE) for hepatocellular carcinoma (HCC) in patients with a cirrhotic liver. MATERIALS AND METHODS Twenty-one patients with cirrhosis and 33 HCC nodules received a mean of 2.4 cycles of CHE before orthotopic liver transplantation (OLT). Iodized oil plus doxorubicin (13 patients) or mitoxantrone (eight(More)
BACKGROUND We investigated the effect of iodinated contrast medium concentration on increased neoplastic lesion enhancement and its direct relation to diagnostic efficacy in biphasic spiral computed tomography for detection of hepatocellular carcinoma. METHODS A pilot, single-center, randomized, double-blind, crossover, comparative study was performed and(More)
OBJECTIVE The purpose of our study was to evaluate the effectiveness of intraarterial infusion of paclitaxel incorporated into human albumin nanoparticles for use as induction chemotherapy before definitive treatment of advanced squamous cell carcinoma of the tongue. SUBJECTS AND METHODS Twenty-three previously untreated patients (age range, 27-75 years)(More)
PURPOSE To assess in vivo volumetric repeatability of an automated software algorithm in pulmonary nodules detected during a lung cancer screening trial. MATERIALS AND METHODS This study was approved by an institutional review board. Written informed consent was obtained from all participants. Data were collected from the Multicentric Italian Lung(More)
The Advanced Breast Biopsy Instrumentation (ABBI) system, which uses surgical cannulas up to 20 mm in diameter, is an alternative to conventional surgical biopsy for the diagnosis of non-palpable breast lesions. Since the need for radiological skill outweighs the surgical content of the technique, we evaluated the feasibility of complete management of the(More)
OBJECTIVE Breast calcifications pose a significant diagnostic and procedural dilemma. We evaluated en bloc stereotactic excision of indeterminate and suggestive microcalcifications for histologic diagnosis using a large-bore cannula biopsy device. MATERIALS AND METHODS We retrospectively reviewed 61 groups of microcalcifications removed with a large-bore(More)
PURPOSE In view of the promising results of a phase I trial, this phase II trial was conducted to study the efficacy and safety of intraarterial induction chemotherapy with a novel nanoparticle albumin-bound paclitaxel formulation in advanced head and neck cancer. MATERIALS AND METHODS Sixty previously untreated patients with locally advanced(More)
