Orbital apex syndrome affecting head and neck cancer patients: A case series
2017
Background Orbital apex syndrome (OAS) is a complex and uncommon disorder that typically damages multiple cranial nerves in association with optic nerve dysfunction. OAS is associated with several different pathologies, however; only a few cases have been reported in association with head and neck cancer (HNC) so far. Material and Methods A case series of HNC patients diagnosed with OAS is described including clinicopathological data, image findings, and disease outcome. Results Ptosis and diplopia were diagnosed in four male patients with mean age of 61.2 years who were undergoing treatment for late-stage carcinomas of the tongue, larynx, and nasopharynx, eventually leading to the diagnosi…
Hypothyroidism in patients treated with radiotherapy for head and neck carcinoma: standardised long-term follow-up study
2016
AbstractObjective:Hypothyroidism is a common complication when radiotherapy is part of the treatment for head and neck tumours. This study aimed to show the incidence of hypothyroidism and possible risk factors in these patients.Methods:Factors related to the population, tumour, treatment and occurrence of hypothyroidism were analysed in 241 patients diagnosed with head and neck carcinoma.Results:Approximately 53 per cent of patients were diagnosed with radiation-induced hypothyroidism. Its occurrence was related to: tumour location, laryngeal surgery type, neck dissection type, post-operative complications, cervical radiotherapy and radiotherapy unit type (linear particle accelerator or te…
Transoral laryngeal microsurgery for early-stage laryngeal basaloid squamous cell carcinoma
2021
A 71-year-old man presented to our otolaryngology clinic with dysphagia and dyspnoea. He had a history of smoking for 40 years. Laryngoscopy showed an exophytic, round mass on the left aryepiglottic fold that was entirely excised by transoral laser CO2 microsurgery. Histological assessment revealed a pT1 basaloid squamous cell carcinoma (BSCC) with free-margin resection. He underwent close follow-up and after 3-year follow-up, the patient was free from disease. Laryngeal BSCC is a rare cancer with poor prognosis due to its late diagnosis and early neck node metastases. We report a rare case of early tumour treated by endoscopic surgery without complications or recurrence of disease. However…
Double-blind, randomized pilot study of bioadhesive chlorhexidine gel in the prevention and treatment of mucositis induced by chemoradiotherapy of he…
2015
Background: To evaluate, in an initial way, the effectiveness of bioadhesive chlorhexidine gel 0.2% versus placebo as a preventive and therapeutic intervention of oral mucositis induced by radiation therapy and chemotherapy in patients diagnosed with head and neck cancer treated with chemoradiotherapy. Material and Methods: In this pilot study, 7 patients (range of age: 18- 65), having histological documented diagnosis of squamous carcinoma on the head and neck region in stage III and IV, and receiving combined radiation treatment and chemotherapy (cisplatin 100 mg/m2 IV on days 1, 22, and 43 of irradiation) were studied. Simultaneously, a topical application was performed with bioadhesive …
Hydroxyurea modulates 5-fluorouracil antineoplastic activity in advanced head and neck carcinoma pretreated with chemotherapy
1992
After informed consent 21 patients with advanced head and neck cancer resistant to folinic acid/5-fluorouracil (FA/5FU + cisplatin) were treated with weekly FA/5FU plus low dose hydroxyurea (HU) to evaluate if HU could further modulate 5FU antineoplastic activity. Five patients achieved a partial response (23.8%) which was short-lived (mean duration 6.5 months). Three patients (14%) had stable disease and 13 (62%) progressed. Among responders, four patients had epidermoidal carcinoma and one had clear cell carcinoma. Treatment was well tolerated and 5FU-related toxicity was not apparently worsened by the addition of HU. The most frequent toxicities were nausea/vomiting (81%), diarrhea (52%)…
Survival of Patients with Oral Cavity Cancer in Germany
2012
The purpose of the present study was to describe the survival of patients diagnosed with oral cavity cancer in Germany. The analyses relied on data from eleven population-based cancer registries in Germany covering a population of 33 million inhabitants. Patients with a diagnosis of oral cavity cancer (ICD-10: C00-06) between 1997 and 2006 are included. Period analysis for 2002-2006 was applied to estimate five-year age-standardized relative survival, taking into account patients' sex as well as grade and tumor stage. Overall five-year relative survival for oral cavity cancer patients was 54.6%. According to tumor localization, five-year survival was 86.5% for lip cancer, 48.1% for tongue c…
Head and neck paragangliomas: Report of 175 patients (1989-2010)
2011
Attention of the otorhinolaryngologist needs to be drawn to the versatile aspects of head and neck paragangliomas (PGLs).This study is a retrospective, nonrandomized clinical study of all 175 individuals with PGLs treated in our department between 1989 and 2010. A genetic analysis was performed on 86 patients.The 175 patients presented 224 head and neck PGLs as well as 2 thyroid papillary carcinomas. Genetic analysis resulted in 1 patient positive for a von Hippel-Lindau (VHL) gene mutation and 34 for succinate dehydrogenase (SDH) gene mutations (22 SDHD, 7 SDHC, and 5 SDHB), 12 of the latter carrying a novel mutation. Thirty-three patients (18.9%) had multiple PGLs and 11 patients (6.3%) h…
Clinical-pathological and sociodemographic factors associated with the distant metastasis and overall survival of oral cavity and oropharynx squamous…
2020
Background The objective of this study was to evaluate the influence of clinical-pathological and sociodemographic factors on the prevalence of distant metastasis (DM) and overall survival in patients with oral cavity and oropharynx squamous cell carcinoma (OOSCC). Material and Methods Cross-sectional study based on the records of 404 OOSCC patients evaluated for DM, covering the period 2000-2014. We analysed the influence of age, sex, level of schooling, primary tumor subsite, treatment, marital status, family history of cancer, history of smoking and alcohol consumption, type of health care coverage (private vs. public) and overall survival. Findings were submitted to Fisher’s exact test,…
Olfaction in chemotherapy for head and neck malignancies
2015
Abstract Objective Systemic chemotherapy for different malignancies occurs alongside various side effects, including reduced sensory function. To date, little is known about the effect of chemotherapeutic agents on olfaction. The aim of this study was to provide new data about changes in sense of smell during chemotherapy among patients with advanced squamous cell carcinomas of the head and neck region. Methods In a prospective, controlled cohort study of patients undergoing up to three courses of chemotherapy (cis- or carboplatin, 5-fluorouracil and docetaxel), olfaction was evaluated prior to and directly following completing a cycle, as well as 3 weeks later with the beginning of the nex…
Is the injection of tramadol effective at control of pain after impacted mandibular third molar extractions? A systematic review and meta-analysis.
2022
Third molar extraction is among the most common surgical procedures performed by oral-maxillofacial surgeons. Postoperative pain, swelling and trismus are common, especially in wisdom teeth, due to trauma to local tissues and the duration of the surgical procedure, among other factors. This systematic review was conducted in accordance with the ?Preferred Reporting Items for Systematic Reviews and Meta-Analyses? in order to answer the focused question: ?Is the local submucosal injection of tramadol effective at the control of postoperative pain in patients submitted to impacted mandibular third molar extractions??. We analyzed papers published until March 30, 2021 in the MEDLINE|PubMed, Web…
