Histopathological profile of patients diagnosed with malignant tumors assisted in a hospital of reference of Agreste Pernambucano

ABSTRACT Cancer is considered a public health problem and is commonly known because of its high mortality rate worldwide. The histopathological evaluation is a fundamental requirement to determine the nature of the lesion, thus it is considered the gold standard examination for diagnosis of neoplasia. The present study aims to evaluate the histopathological profile of patients with malignant tumors diagnosed at a reference hospital in the Agreste Pernambucano. A cross-sectional, descriptive study of a quantitative documentary survey was conducted using the database of the clinical analysis laboratory of the referred Hospital in the field of pathology in the year 2016. A total of 74 cases were selected, and the male gender was the most affected. The age group of patients with the highest prevalence was between 50 and 70 years of age. Clinical characteristics: The most prevalent anatomical location with tumors was both the colon/rectum (30%) and skin (30%). The most common histological type was adenocarcinoma (47.2%). The pathological profile of cancer patients in the region studied were characterized, which served as a database for future epidemiological studies and as a subsidy for the implementation of preventive public policies for the population of this region.RESUMEN El c áncer es considerado unproblema de salud pública y es comúnmente conocidopor su alta tasa de mortalidad en el mundo. La evaluación histopatológica es fundamental para d...

Authors: Zeng X, Liu Q, Yang Y, Jia W, Li S, He D, Ma R Abstract Placenta-specific protein 8 (PLAC8) is a conserved protein with a molecular weight of 12.5 kDa. The specific function of this protein has not been fully elucidated, however, PLAC8 has been found to play an important tumor regulatory role in certain types of cancer, including colon, pancreatic and liver cancer. PLAC8 also participates in the regulation of the cell cycle, autophagy, epithelial-mesenchymal transition and other cellular functions, indicating its potential as a molecular target worth further investigation. The present study investigated th...

Nuclear factor erythroid 2-related factor 2 (Nrf2), a master regulator of many cytoprotective genes, plays a protective role in carcinogenesis. Recent studies have identified a specific gene-expression signature regulated by the Nrf2 pathway in lung adenocarcinoma and head-and-neck squamous cell cancer. However, the roles of Nrf2 in the development of colitis-associated colorectal...

ConclusionThe downregulatedCDX2 expression is associated with female gender, right-sided tumors, mucinous tumors, lymph node involvement, high-grade tumor, and advanced overall pathological staging and can be considered as a possible prognostic factor for patients follow-up. However, our study is a preliminary study and further studies with larger sample sizes in different ethnic groups are required.

ConclusionThe results of our series of 13 cases indicate that intraoral soft tissue metastatic carcinomas have a male predilection with a male to female ratio of 11:2, are commonly found in the gingiva and alveolar mucosa (76.9%), present frequently as an easy-bleeding pyogenic granuloma-like lesion (92.3%). In addition, the most common primary cancer site is the liver.

This study was designed to determine whether dietary tricin exerts inflammation-associated colon carcinogenesis induced by azoxymethane (AOM) and dextran sulfate sodium (DSS) in mice. Male Crj: CD-1 mice were initiated with a single i.p. injection of AOM (10 mg/kg bw) and followed by a 1-week exposure to DSS (1.5%, w/v) in drinking water to induce colonic neoplasms. They were then given the experimental diet containing 50 or 250 ppm tricin. The experiment was terminated at week 18 to determine the chemopreventive efficacy of tricin. The effects of dietary tricin on the expression of several inflammatory cytokines, includin...

ConclusionThe fusion fascia of Fredet is useful to achieve CME and D3-L in right colon cancers with reduced risk of intraoperative complications. This structure is particularly suitable for minimally invasive surgery; therefore, we encourage awareness of the fascia of Fredet by colorectal surgeons.

We report the first case of a patient with colon cancer who was diagnosed with a thyroid metastasis in a noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). A 55-year-old male patient presented with a 19  mm thyroid nodule in the inferior left lobe. It was EU-TIRADS 5 on echography and suspicious of papillary thyroid carcinoma (Bethesda V) on cytology. Macroscopically, the nodule was fleshy and completely encapsulated. At frozen section examination, it demonstrated follicular architecture with mild atypia. Inside the nodule was a focus of tumor with glandular architecture, marked cell...

;F, Yener Z Abstract The aim of this study was to investigate the chemopreventive effects of juniper berry (JB) oil on azoxymethane (AOM)-induced colon cancer in rats. Thirty-two male Wistar albino rats were allocated into four groups: Control, AOM, AOM + JB, and JB groups. Whereas the control group was fed with standard pellet feed, the AOM and AOM + JB groups were administered of AOM (15 mg/kg body weight) subcutaneously once every 2 weeks for 10 weeks. AOM + JB and JB groups additionally received JB oil (100 µl/kg) orally. At the end of the 16...

ConclusionTo optimize targeting and visualization of the surgical field in right pelvic sidewall/paracolic gutter, robotic arms can be placed in a straight line from above the pubic symphysis extending to the left subcostal line and between the midline vertical and midclavicular lines. Robotic tumor debulking should be considered in selected patients with recurrent ovarian cancer who present with oligo-metastatic disease, in the absence of carcinomatosis.

Abstract Older patients who are diagnosed with colon cancer face unique challenges, specifically regarding to cancer treatment. The aim of this study was to identify prognostic signatures to predicting prognosis in colon cancer patients through a detailed transcriptomic analysis. RNA-seq expression profile, miRNA expression profile, and clinical phenotype information of all the samples of TCGA colon adenocarcinoma were downloaded and differentially expressed mRNAs (DEMs), differentially expressed lncRNAs (DELs) and differentially expressed miRNAs (DEMis) were identified. A competing endogenous RNA (ceRNA) network ...
