In subgroups of breast cancer, the shortest disease-free and overall survival was observed in basaloid and human epidermal growth factor receptor-2 groups. CK5/6 expression is a marker used in diagnosing breast cancers in basaloid group and is associated with a poor prognosis. Similarly, loss of tumor suppressor gene PTEN and a high expression of c-Met has been associated with poor prognosis in breast cancer and many other cancers. In this study, we aimed to determine the effect of CK5/6 and c-Met expressions, and PTEN loss on the disease prognosis in triple-negative breast cancer patients. Ninety-seven patients pathologically diagnosed with triple-negative breast cancer were enrolled. The clinical and pathological characteristics of the patients were recorded. c-Met, PTEN, and CK5/6 expressions were evaluated with immunohistochemical methods from paraffin blocks. The median age of patients was 47 years. CK5/6 positivity was 50.5 %, PTEN loss was 44.3 %, and high c-Met expression was detected in 53.6 %. In multivariate analysis, predictors of the recurrence were loss of PTEN (HR = 2.99; P = 0.004), high c-Met expression (HR = 2.05; P = 0.06), CK5/6 expression (HR = 2.99; P = 0.02), increase in the number of metastatic lymph nodes (HR = 1.11; P = 0.001), and an increase in tumor size (HR = 1.226; P = 0.01). Also, PTEN loss (HR = 2.43; P = 0.05), CK5/6 expression (HR = 3.74; P = 0.01), and N2-3 tumors compared to negatives (HR = 3.63; P = 0.01) were associated with death. PTEN loss correlated with those of lymphovascular invasion. There was a correlation between CK5/6 expression and the number of metastatic lymph nodes. Also, a correlation was found among cancers with highly expressed levels of c-Met, T1-2 tumors, and high-grade tumors. The classical markers, lymph node involvement and tumor size, were found to be of prognostic value; however, high c-Met and CK5/6 expressions, and PTEN loss were found to increase risk of recurrence and death in patients with triple-negative breast cancer.
Teratomas originating from the oral cavity are named as epignathus. It is a rare type of teratoma. An 11-day old male newborn was diagnosed with cleft palate and intraoral masses. The mass on the right side was protruding from the mouth. Another one on the left side was extending from the nasopharynx to the oropharynx. The diagnosis of mature teratoma was made based on the histopathological study of surgically excised masses. We desired to report on this case since multiple localized epignatus in a newborn with cleft palate has not been described yet in the literature.
Immunoglobulin M nephropathy (IgMN) is a glomerular disease that may be identified in all age groups, but children and young adults appear to have been affected more frequently in some series. The clinical picture could differ from hematuria to rapidly progressive glomerulonephritis. The main characteristics in pathologic examination are mesangial hypercellularity with a diffuse and granular immunoglobulin M deposition in the glomerular structure. To date, a standardized protocol has not been proposed for IgMN treatment. Systemic corticosteroids, calcineurin inhibitors, cyclophosphamide, and rituximab were agents reported in the literature. We present a 30-year-old woman admitted to the hospital for edema in the lower extremities at the 31st week of pregnancy. She had one abortus previously, and this was her second pregnancy. Renal biopsy performed after delivery was reported as IgMN with mesangial proliferation. She received 1 mg/kg/day prednisone therapy achieving complete remission. This report is the first case of IgMN developed in pregnancy.
The aim of the study is to evaluate retrospectively the results of human papilloma virüs (HPV) screening test started at our center, to identify the rates of high risk HPV (hrHPV) causing /not causing cellular anomalies and HPV16, 18/45 genotypes, to review the concordance of smear results and biopsy, and to compare our results with the similar studies conducted in different parts of the world and our country.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
