objectives: presence/absence of cervical lymph node metastasis plays a critical role in prognosis and survival of patients with oral squamous cell carcinoma (scc). this study was designed to assess the diagnostic accuracy of computed tomography (ct) scan for detection of cervical lymph node metastasis in oral scc in comparison with histopathological analysis after neck dissection methods: in th...

PurposeTo present the first-year experience of treating patients using intensity-modulated radiation therapy (IMRT) and stereotactic body (SBRT) with biology-guided (BgRT) machine, X1 system, installed in a clinical setting.MethodsA total 78 were treated on system IMRT SBRT from May 2021 to 2022. Clinical technical data including treatment sites, number pre-treatment kilovoltage computed tomogr...

Background: Intensity-modulated radiation therapy (IMRT) is now the method of choice for the treatment of patients with complex-shaped planning target volumes (PTV) targets, especially when concave targets are close to a larger number of organs-at-risk (OAR) as in patients with advanced head and neck cancer. Patients and Methods: Fifteen patients with advanced head and neck cancers (oropharynx,...

PURPOSE To quantify the radiobiological advantages obtained by an Improved Forward Planning technique (IFP) and two IMRT techniques using different fractionation schemes for the irradiation of head and neck tumours. The conventional radiation therapy technique (CONVT) was used here as a benchmark. METHODS Seven patients with head and neck tumours were selected for this retrospective planning ...

External Beam Radiotherapy (EBRT) remains the mainstay for radical treatments, in malignancies in head and neck regions. Teletherapy with cobalt-60 isotope machines are still available for cancer management in countries with more population, and their continuation as a basic machine has been recommended [1]. With linear accelerators, the present day radiotherapy for radical treatments in head a...

CT: computed tomography HNCSCC: head and neck cutaneous squamous cell carcinoma IMRT: intensity-modulated radiation therapy MMS: Mohs micrographic surgery PNI: perineural invasion RT: radiation therapy SCC: squamous cell carcinoma INTRODUCTION Head and neck cutaneous squamous cell carcinoma (HNCSCC) is a growing problem in the immunosuppressed population, and the behavior of these cancers can b...

introduction: vascular abnormalities are relatively uncommon lesions, but head and neck is a common region for vascular malformation which is classified as benign tumors. in this paper, the authors report a rare presentation of vascular malformation in the tongue and its managements. case report: an 18 months 2 old child presented with a giant mass of tongue which caused functional and aestheti...

background: to investigate the effect of zinc sulphate for prophylaxis of radiation-induced oral mucositis in patients with head and neck cancer. materials and methods: in the department of radiation oncology, ankara numune education and research hospital, 40 patients with head and neck cancer were selected randomly to receive either zinco-c 25 mg, four tablets daily or control group who did no...
