PURPOSE The development of computer-aided diagnostic (CAD) methods for lung nodule detection, classification, and quantitative assessment can be facilitated through a well-characterized repository of computed tomography (CT) scans. The Lung Image Database Consortium (LIDC) and Image Database Resource Initiative (IDRI) completed such a database, establishing(More)
RATIONALE AND OBJECTIVES The purpose of this study was to analyze the variability of experienced thoracic radiologists in the identification of lung nodules on computed tomography (CT) scans and thereby to investigate variability in the establishment of the "truth" against which nodule-based studies are measured. MATERIALS AND METHODS Thirty CT scans were(More)
Adolescent cancer survivors were compared with nondiseased control subjects on measures of adaptation, coping, body image, sexual adjustment, psychopathology, and family functioning. Cancer survivors reported no major difficulties in social competence, overall coping, and family communication. Although their school teachers reported no symptoms of(More)
Natural killer (NK) cells and NK cell activity were determined in three groups (newly diagnosed [n = 21], on therapy [n = 21], and off therapy [n = 18]) of children with various types of malignant solid tumors and in a control group (n = 26) by means of Leu-7 and Leu-11b monoclonal antibodies and a 4-hour 51Cr-release assay, respectively. The(More)
RATIONALE AND OBJECTIVES To study the agreement in treatment response classifications between unidimensional (1D), bidimensional (2D), and volumetric (3D) methods of measuring metastatic lung nodules on chest computed tomography (CT). MATERIALS AND METHODS Chest CT scans of 15 patients undergoing treatment for metastatic colorectal, renal cell, or breast(More)
Treatment-related cognitive impairments have been reported for survivors of childhood leukemia following prophylactic central nervous system (CNS) treatment with craniospinal radiation. We examined the neurocognitive status of 46 children with acute lymphocytic leukemia (ALL) to assess the impact of a regimen consisting of systemic chemotherapy and(More)
Iatrogenic cognitive impairments have been reported for survivors of childhood leukemia after prophylactic central nervous system therapy with craniospinal radiation. To determine whether chemotherapy alone might be a source of central nervous system damage, we assessed in a cross-sectional design the cognitive and academic functioning of 48 children with(More)
Quantitative image analysis (QIA) goes beyond subjective visual assessment to provide computer measurements of the image content, typically following image segmentation to identify anatomical regions of interest (ROIs). Commercially available picture archiving and communication systems focus on storage of image data. They are not well suited to efficient(More)
The authors performed a Phase I study to assess the toxicity and hematologic effect of recombinant human interleukin-2 (rIL-2) in seven children with advanced malignancies. The rIL-2 was given as a bolus injection of 1 or 3 X 10(6) U/m2/dose three times a week (Monday, Wednesday, and Friday) for 3 weeks. No life-threatening toxicity occurred with the dose(More)
Five cases of relapsing acute lymphocytic leukemia (ALL) presenting as an ovarian tumor have been treated at this institution, representing the largest reported series. In a review of the literature we identified 18 additional cases of ovarian leukemic relapse. Together, these 23 patients form the basis for this report. Abdominal pain is the most common(More)
