We report a case of adenocarcinoma arising in a focus of heterotopic pancreas, occurring in the stomach of a 52-year-old man. The patient presented with gastric outlet obstruction. Radiographic studies revealed thickening of the gastric wall, but endoscopy failed to reveal a mucosal abnormality. A 50% distal gastrectomy was performed, along with vagotomy.(More)
BACKGROUND Hypermethylation of CpG islands in the promoter regions of tumor suppressor genes is one mechanism of tumorigenesis. Caveolin-1 (Cav-1), a gene coding for the structural component of cellular caveolae, is involved in cell signaling and has been proposed to be a tumor suppressor gene in several malignancies. This gene maps to 7q31.1, a site known(More)
There is a clear genetic component to prostate cancer susceptibility. Regions reported to be linked to prostate cancer include 1q24-25 (HPC-1), 1q42.2-43, and Xq27-28. There is limited genetic information on familial prostate tumors. We used the Utah Population Database to identify familial prostate cancer cases and selected 35 cases from high-risk(More)
This study was designed to determine if cytological detection of 5-methylcytosine (5MC) was feasible on prostate tumor sections and to determine if levels of 5MC differed in malignant compared to normal prostate tissue. We further sought to see if 5MC levels correlated with any clinical outcome data. Thirty prostate tumor sections were obtained from(More)
Twenty prostate tumor specimens, obtained from radical prostatectomies, and two lymph node metastases were examined by classical and molecular cytogenetic methods. A sample from each tumor was analyzed histologically and used for touch preparations. Adjacent samples were used for preparation of single-cell suspensions before cell culture (DirFISH) and for(More)
New anticancer drugs targeting DNA topoisomerase I (topo I) are showing activity against human sarcomas. Laboratory studies have indicated that cells responsive to topo I-targeted drugs have elevated levels of topo I, require active DNA replication, and may require a functional apoptotic pathway. In this study, we evaluated these potential markers of topo(More)
A patient with spurious automated leukopenia secondary to in vitro aggregation of neutrophils is evaluated. The primary importance of this transient phenomenon is the potential generation of unnecessary clinical investigation and diagnostic expense. The cause of this phenomenon is not related to time, temperature, or type of anticoagulant. The true(More)
Analysis of 20 primary prostatic tumors (local Gleason grades ranging from 1 to 4) was performed on archival material obtained from formalin-fixed, paraffin-embedded blocks. Alpha satellite probes specific for the pericentric regions of chromosomes 12, 17, X, and Y were used in fluorescence in situ hybridization (FISH) assays for the examination of(More)
Same-day turnaround of pathology specimens is desirable in this era of managed care, and rapid microwave tissue processing produces histologic features of a quality equivalent to overnight processing. We studied whether microwave-assisted rapid tissue processing adversely affects the quality of immunohistochemical staining. We selected 30 specimens (20(More)
