Central nervous system neoplasms with combined features of malignant glioma and primitive neuroectodermal tumor (MG-PNET) are rare, poorly characterized, pose diagnostic as well treatment dilemmas. We studied 53 MG-PNETs in patients from 12 to 80 years age (median = 54 years). The PNET-like component consisted sharply demarcated hypercellular nodules evidence neuronal differentiation. Anaplasia, seen medulloblastomas, was noted 70%. Within the element, N-myc or c-myc gene amplifications were...
In Brief We have reviewed clinically, morphologically, and immunophenotypically a series of 14 Epstein-Bar virus (EBV)+ cutaneous natural killer cell (NK)/T-cell lymphoma from Peru. Most (11 out 14) these cases fit well into the category Hydroa vacciniforme-like (HVLL), but 3 different clinical presentation, without facial involvement. all cases, skin lesions present in both sun-exposed nonexposed areas exhibited slowly progressive relapsing course, changing edema, to blistering, ulceration,...
More than 180 single nucleotide polymorphisms (SNPs) associated with breast cancer susceptibility have been identified; these SNPs can be combined into polygenic risk scores (PRS) to predict risk. Because most were identified in predominantly European populations, little is known about the performance of PRS non-Europeans. We tested a 180-SNP Latinas, large ethnic group variable levels Indigenous American, European, and African ancestry.We conducted pooled case-control analysis US Latinas...
Evaluation of features related to infiltrating immune cell level in glioblastoma.Tumor-infiltrating lymphocytes (TILs) through H&E staining, and TILs (CD3, CD4, CD8 CD20) macrophage (CD68 CD163) levels immunohistochemistry were evaluated digital analysis.CD68 (9.1%), CD163 (2.2%), CD3 (1.6%) had the highest density. Higher CD4+ was associated with unmethylated MGMT (p = 0.016). CD8+ larger tumoral size 0.027). CD163+ higher age 0.044) recursive partitioning analysis 4. Women < 0.05), total...
Women of Latin American origin in the United States are more likely to be diagnosed with advanced breast cancer and have a higher risk mortality than non-Hispanic White women. Studies U.S. Latinas women reported high incidence HER2 positive (+) tumors; however, factors contributing this observation unknown. Genome-wide genotype data for 1,312 patients from Peruvian Genetics Genomics Breast Cancer Study (PEGEN-BC) were used estimate genetic ancestry. We tested association between status...
BACKGROUND Astroblastoma is an extremely rare tumor of the central nervous system, and its origin validity as a different entity are still being debated. Because rarity similarities to other glial neoplasms, it often misdiagnosed, impacting treatment outcomes. OBSERVATIONS very mainly affects children young adults. It does not have definitive World Health Organization grade divided into low- high-grade categories. The clinical presentation consistent with signs intracranial hypertension....
