The incidence of cutaneous squamous cell carcinoma (CSCC) and its precursor lesions argues the research for validating markers that would define the biomolecular mechanisms behind the potential progression and aggressiveness of these lesions. In this study, we analyzed the expression of p53, p16 and Ki67 in 91 cases of CSCC and its precursors in relation with the histological prognostic paramet...
Aim. We aim to compare immunophenotypic characteritics of atypical epithelium (AE) with COVID-19-induced diffuse alveolar damage (DAD) and pulmonary lepidic-growth adenocarcinoma, accounting for cell cycle control, proliferation differentiation]. Methods. examined tissue specimens from twenty-four fatal cases acute respiratory syndrome confirmed by autopsy (Group 1) four adenocarcinoma 2). Perp...
Objective: HPV and EGFR expression status may be utilized as an independent prognostic factor owing to the different clinical demographic characteristics head neck cancers. In study, it was aimed investigate association between EGFR, p16 ki67 survival in patients with squamous cell carcinoma (SCC).Materials Methods: A total of 43 SCC region were included study. Ki67 examined by means immunohist...
PURPOSE The purpose of this study is to clarify the prognostic significance of expression of Jab1, p16, p21, p62, Ki67 and Skp2 in soft tissue sarcomas (STS). Optimised treatment of STS requires better identification of high risk patients who will benefit from adjuvant therapy. The prognostic significance of Jab1, p16, p21, p62, Ki67 and Skp2 in STS has not been sufficiently investigated. EXP...
مقدمه : ضایعات پیش سرطانی و سرطان داخل اپی تلیوم دهانه رحم طیف پیوسته ای از تغییرات مورفولوژیک هستند که مرزهای دقیق آنها نسبتاً نامشخص است . استفاده از روشهای ایمنوهیستوشیمی ونشانگرهای پرولیفراتیو روش قابل اعتمادی در طبقه بندی ضایعات مختلف دیسپلازی دهانه رحم است . در مطالعات انجام شده از نشانگرپرولیفراتیو ki67 به عنوان فاکتور پیشگویی کننده پیشرفت ضایعات سرطانی دهانه رحم استفاده شده است . این م...
BACKGROUND Oral submucous fibrosis (OSF) is a chronic progressive disease of the oral cavity that is considered a common potentially malignant disorder in South Asia. Areca nut chewing is the main etiological factor, but its carcinogenic mechanism has yet to be proven. The purpose of this study was to identify the useful biomarkers in predicting high-risk patients with OSF. METHODS Thirty-six...
BACKGROUND Cell proliferation is one of the most critical factors in metastasis and prognosis of the malignant tumors.Recent investigations show that the eosinophil granolosytes have an important role in developing of malignant tumors. The relation between cell proliferation and eosinophilic infiltration in oral squamous cell carcinoma (OSCS) with prognosis is unclear. The aim of this study was...
BACKGROUND The purpose of this study was to test whether immunohistochemical (IHC) Ki67 levels after short-term preoperative hormone therapy (post-Ki67) predict similar numbers of patients with favorable prognoses as genomic markers. RESULTS Thirty paired cases (60 samples) were enrolled in this study. Post-Ki67 levels were significantly lower than pre-treatment Ki67 levels (P < 0.001). Post-...
