The aim of this study was to evaluate the histopathologic parameters that predict lymph node metastasis in patients with oral squamous cell carcinoma (OSCC) and design a new assessment score on basis these could ultimately allow for changes treatment decisions or aid clinicians deciding whether there is need close follow-up perform early dissection. Histopathologic 336 cases OSCC stage cT1/T2 N0M0 disease were analyzed. location tumor type surgery used management recorded all patients....

BACKGROUND The aim of this study is to describe the trends and variations in global burden gallbladder cancer (GBC) with an emphasis on geographic female gender. METHODS Data (2012‐2030) relating GBC was extracted from GLOBOCAN 2012 database analyzed. RESULTS results our document a rising gender variations. highest noted WPRO region (based WHO regions), Asia continents) India, Chile, China countries). less developed regions world account for majority GBC. are also present within individual...

Stable isotope records of oxygen and hydrogen were studied from a 65 m long ice core retrieved central Dronning Maud Land, East Antarctica, in order to reconstruct the coastal Antarctic climate variability during last century its relation Southern Annular Mode (SAM) El Niño‐Southern Oscillation (ENSO). The δ 18 O showed significant SAM with dominant ∼4 years variability, except specific periods (1918–1927, 1938–1947, 1989–2005) when ENSO teleconnection was established through in‐phase...

Aims Programmed death‐ligand 1 ( PD ‐L1), a potential target for immune checkpoint inhibitors in various solid neoplasms, has been studied very few cases of Gall Bladder Carcinoma GBC ). The current study aimed to evaluate ‐L1 expression at primary and metastatic sites , its associations with standard prognostic clinicopathological parameters, as well overall survival. Methods results One hundred seventy‐four were evaluated by the use SP 263 clone tissue microarrays. Clinicopathological...

Objective: The present study was undertaken to explore the clinicopathological profile of bronchogenic carcinoma. Methodology: Four hundred consecutive patients with histopathologically proven carcinoma, hospitalized between 1985 and 1999 at a large teaching tertiary care referral hospital King George's Medical University in Lucknow, India, were analysed. Results: average age carcinoma 57 years; 9.8% less than 40 years age; ratio male female 4.3:1.0; 71% smokers; 87% smoking bidi smokers....

High-resolution records of nitrate (NO 3 − ), oxygen isotope (δ 18 O) and non-sea salt sulphate (nssSO 4 2− ) were studied using an ice core collected from central Dronning Maud Land in East Antarctica to identify the influence environmental variability on accumulation NO over past 450 years. The results confirmed that multiple processes responsible for production preservation Antarctic ice. Correlation between nssSO peaks revealed aerosols released during major volcanic eruptions might have...

Abstract Background Coronavirus disease 2019 (COVID‐19) has impacted cancer care globally. The aim of this study is to analyze the impact COVID‐19 on healthcare from perspective patients with cancer. Methods A cross‐sectional survey was conducted between June 19, 2020, August 7, using a questionnaire designed by awaiting surgery. We examined five domains (financial status, access, stress, anxiety, and depression) their relationship various patient‐related variables. Factors likely determine...

Despite improved therapeutics in oral squamous cell carcinoma (OSCC), tumor cells that are either quiescent and/or endowed with stem cell-like attributes usually survive treatment and recreate load at relapse. Through this study, we aimed strategically to eliminate these cancer using a combination drug approach.Primary cultures from 15 well-moderately differentiated OSCC were established, the existence of characteristics five (CSC) specific markers - CD44, CD133, CD147, C166, SOX2 spheroid...
