Although the decline in cancer mortality rates with the advent of combination antiretroviral therapy (cART) in HIV-infected individuals can be mostly explained by a decrease in cancers incidence, we looked here if improved survival after cancer diagnosis could also contribute to this decline. Survival trends were analyzed for most frequent cancers in the HIV-infected population followed in the ...
During the last decade, gene expression profiling of breast cancer has revealed the existence of five molecular subtypes and allowed the establishment of a new classification. The basal subtype, which represents 15-25% of cases, is characterized by an expression profile similar to that of myoepithelial normal mammary cells. Basal tumors are frequently assimilated to triple-negative (TN) breast ...
Glomus tumors (GTs) are benign tumors originating from the glomus body which are usually solitary and small lesions. The vast majority are found in the distal extremities, particularly in the hand, wrist, foot and under the fingernails rarely involving visceral organs. Here we report a rare case of gastric GT presented to us with exsanguinating hematemesis and severe anemia. All the initial dia...
Cohorts of 4- to 5-wk-old female Fischer 344 rats received four biweekly 1.5-mg doses of N-methyl-N-nitrosourea (MNU) intravesically and were sacrificed at various intervals. By 13 wk after initiation of the carcinogen, all animals have flat epithelial atypia and/or papillary transitional cell bladder carcinomas, and 67% of the lesions are histological Grade II or III. By 20 wk, 83% have gross ...
Adrenocortical carcinomas are rare tumors in adults. They can be hormonally active and detected by a hormonal excess, or be non-secretory tumors. In the latter case, they become symptomatic after a long period of growth, usually after they have already invaded the surrounding tissues. In these cases, multiple visceral resections are sometimes required in order to obtain a complete R0 resection....
Abstract Visceral leishmaniasis (Kala-azar) is a systemic infection disease that can be diagnosed by some invasive procedures such as splenic, liver biopsy or bone marrow aspiration, whichare determined as the gold standards for diagnosing of this disease. At present, a variety of noninvasive tests having different specificities and sensitivities are available for the diagnosis of visceral ...
Introduction. The aim of this study was to investigate the effects of high fat diet-induced obesity and interval and continuous exercise training on visceral fat SIRT1 and insulin resistance in male rats. Method. Forty male rats were divided into two groups: high-fat diet (HFD; n=32) and standard diet (C; n=8). After 10 weeks inducing obesity, eight rats from the HFD and C groups were sacrifi...
Two cases of adult testicular teratoma with shadow cell differentiation (SCD) similar to that seen commonly in pilomatrixoma are presented. The patients aged 21 and 27 years, and both tumors were limited to the testis. The differentiation of squamous epithelium toward shadow cells is well known in cutaneous pilomatrixoma and related lesions, some odontogenic tumors, craniopharyngeoma, and it wa...
BACKGROUND Bone is a preferred target for circulating metastatic breast cancer cells. We found that the CD9 protein was up-regulated in the B02 osteotropic cell line, derived from the aggressive parental MDA-MB-231 breast cancer cell line. Here, we investigated the putative relationship between CD9 expression and the osteotropic phenotype. MATERIALS AND METHODS Overexpression of CD9 was analy...
von Hippel-Lindau disease (VHL) is a familial neoplasia syndrome associated with multisystem tumor development. Depending on tumor type and location, current treatments for VHL-associated tumors can include a combination of chemotherapy, radiation therapy, and/or surgery. Central nervous system (CNS) manifestations of VHL include craniospinal hemangioblastomas and endolymphatic sac tumors (ELST...
