Analysis of salivary mycobiome in a cohort of oral squamous cell carcinoma patients from Sudan identifies higher salivary carriage of malassezia as an independent and favorable predictor of overall survival
Mohamed, Nazar; Litlekalsøy, Jorunn; Ahmed, Israa Abdul Rhman; Martinsen, Einar Marius Hjellestad; Furriol, Jessica; Javier-Lopez, Ruben; Elsheikh, Mariam; Mohamed, Nuha Mohamed Gaafar; Morgado, Luis; Mundra, Sunil; Johannessen, Anne Christine; Osman, Tarig Al-Hadi; Nginamau, Elisabeth Sivy; Suleiman, Ahmed; Costea, Daniela Elena (Journal article; Peer reviewed, 2021-10-12)Background: Microbial dysbiosis and microbiome-induced inflammation have emerged as important factors in oral squamous cell carcinoma (OSCC) tumorigenesis during the last two decades. However, the “rare biosphere” of the ... -
Characterization of immune cell infiltrate in tumor stroma and epithelial compartments in oral squamous cell carcinomas of Sudanese patients
Mohamed, Nuha Mohamed Gaafar; Osman, Tarig Al-Hadi; Ahmed, Israa A.H.; Elsheikh, Mariam; Dongre, Harsh Nitin; Jacobsen, Martha Rolland; Mohamed, Nazar; Fromreide, Siren; Suleiman, Ahmed Mohamed; Johannessen, Anne Christine; Nginamau, Elisabeth Sivy; Costea, Daniela Elena (Journal article; Peer reviewed, 2021)Background Tumor immune infiltrate has been explored in oral squamous cell carcinoma (OSCC), but studies on simultaneous characterization of multiple immune cell subtypes separately in stromal and intraepithelial tumor ... -
A combined histo-score based on tumor differentiation and lymphocytic infiltrate is a robust prognostic marker for mobile tongue cancer
Bjerkli, Inger-Heidi; Hadler-Olsen, Elin Synnøve; Nginamau, Elisabeth Sivy; Laurvik, Helene; Søland, Tine Merete; Costea, Daniela Elena; Uhlin-Hansen, Lars; Steigen, Sonja Eriksson (Journal article; Peer reviewed, 2020-06-30)We wanted to evaluate the prognostic value of common histopathological variables in a large cohort of patients with cancer in the mobile tongue as such information can be important for treatment stratification of the ... -
Combined in situ hybridization and immunohistochemistry on archival tissues reveals stromal microRNA-204 as prognostic biomarker for oral squamous cell carcinoma
Rajthala, Saroj; Dongre, Harsh; Parajuli, Himalaya; Min, Anjie; Nginamau, Elisabeth Sivy; Kvalheim, Arild; Lybak, Stein; Sapkota, Dipak; Johannessen, Anne Christine; Costea, Daniela Elena (Journal article; Peer reviewed, 2021)Micro-RNAs (miRs) are emerging as important players in carcinogenesis. Their stromal expression has been less investigated in part due to lack of methods to accurately differentiate between tumor compartments. This study ... -
Epithelial PD-L1 expression at tumor front predicts overall survival in a cohort of oral squamous cell carcinomas from Sudan
Mohamed, Nuha Mohamed Gaafar; Osman, Tarig Al-Hadi; Elsheikh, Mariam; Alhaj Ahmed, Israa Abdul Rhman Hassaballah; Dongre, Harsh Nitin; Fromreide, Siren; Suleiman, Ahmed M.; Johannessen, Anne Christine; Nginamau, Elisabeth Sivy; Costea, Daniela Elena (Journal article; Peer reviewed, 2022)Background We recently described the tumor immune microenvironment (TIME) in oral squamous cell carcinomas (OSCC) from Sudan by assessing the core of the lesions. However, the invasive tumor front (ITF) is the most active ... -
Feasibility of a portable electronic nose for detection of oral squamous cell carcinoma in sudan
Mohamed, Nazar; van de Goor, Rens; El-Sheikh, Mariam; Elrayah, Osman; Osman, Tarig; Nginamau, Elisabeth Sivy; Johannessen, Anne Christine; Suleiman, Ahmed; Costea, Daniela Elena; Kross, Kenneth W. (Journal article; Peer reviewed, 2021-05-03)Background: Oral squamous cell carcinoma (OSCC) is increasing at an alarming rate particularly in low-income countries. This urges for research into noninvasive, user-friendly diagnostic tools that can be used in ... -
Grading of oral squamous cell carcinomas – Intra and interrater agreeability: Simpler is better?
Steigen, Sonja E; Søland, Tine Merete; Nginamau, Elisabeth Sivy; Laurvik, Helene; Costea, Daniela-Elena; Johannessen, Anne Christine; Jebsen, Peter Wilhelm; Bjerkli, Inger-Heidi; Uhlin-Hansen, Lars; Hadler-Olsen, Elin Synnøve (Peer reviewed; Journal article, 2020)Background: Numerous studies have been presented on histological grading of oral squamous cell carcinomas (OSCC) for predicting survival, but uncertainty of their usefulness rises due to discordances of results. A scoring ... -
TP53 mutation and human papilloma virus status as independent prognostic factors in a Norwegian cohort of vulva squamous cell carcinoma
