Objectives: studying clinical and paraclinical characteristics of laryngeal cancer. Patients methods: 31 cancer patients were diagnosed treated in the Oncology Department national otorhinolaryngology hospital Vietnam from 11/2022 to 4/2023 by a cross-sectional descriptive study. The results: having most common age range was 60-80 occupied 52.8%, mean 60.5 ± 9.4, ranging 35 80. Males 97.2% (35/3...

To explore the mechanism of microRNA-125a reversing resistance laryngeal cancer stem cells to cisplatin from mitochondrial autophagy. The human carcinoma cell line Hep-2 was purchased Shanghai Bioleaf Biotechnology Co., Ltd. expression messenger RNA in each group analyzed by reverse transcription-polymerase chain reaction. migration and invasion ability evaluated Transwell assay. Cell apoptosis...

Laryngeal spindle cell carcinoma (SpCC) is an uncommon subtype of squamous cell carcinoma which represents 0.5% of all laryngeal squamous cell carcinomas. It is a biphasic tumor consisting of the combination of a malignant mesenchymal spindle cell component and a squamous cell component that includes dysplasia, carcinoma in situ, or invasive carcinoma. Although it has aggressive biological feat...

background : interleukin (il)-4 is a member of t helper 2 (th2) axis produced by t-lymphocyte and mast cell. it has been shown that il-4 expression changes in tumor tissues. the main objective of this study is to investigate the expression of il-4 mrna in patients with laryngeal squamous cell carcinoma (lscc) with or without lymph node involvement. materials and methods: mrna expression of il-4...

AIM This study aims to investigate the possible role of H. pylori as a cause of laryngeal squamous cell carcinoma. METHOD This controlled study was performed with 31 consecutive laryngeal cancer and 28 cancer-free patients who underwent direct laryngoscopy and biopsy of laryngeal lesions. To document the previous H. pylori infection, serological analysis of the antibody titers was done. Immun...

The risk factors affecting the survival rates of laryngeal carcinoma are not well understood. In this study, we investigated the expression status of mutS homolog 2 (MSH2) and mutL homolog 1 (MLH1) and examined the relationship between these two molecules and overall survival rates in laryngeal cancer. We also explored the potential reason for the altered expression of these two genes. Using re...

MicroRNAs (miRNAs) play critical roles in the progression of laryngeal cancer (LC). In this study, we aimed to investigate whether miR-149 is associated with the prognosis of patients with LC. A total of 97 laryngeal squamous cell carcinoma patients who underwent tumor resection were included in our follow-up study. In vitro studies was performed in cancer cell line Hep-2 to explore the antitum...

Cancer has become a major public health problem worldwide and the number of deaths due to this disease is increasing almost exponentially. In the constant search for new treatments, natural products of plant origin have provided a variety of new compounds to be explored as antitumor agents. Tabernaemontana catharinensis is a medicinal plant that produces alkaloids with expressive antitumor acti...
