Función tiroidea postratamiento de cáncer escamoso de orofaringe, hipofaringe y laringe / Thyroid function after oropharyngeal, hypophariyngeal and laryngeal squamous cell carcinoma treatment

Introducción: El hipotiroidismo es una de las complicaciones del tratamiento del cáncer de cabeza y cuello, con incidencias que varían desde 7 por ciento a 57 por ciento. Objetivo: Estimar frecuencia de hipotiroidismo en pacientes con cáncer faringo laríngeo y determinar factores de riesgo. Material y método: Se realizó un estudio transversal, midiendo la función tiroidea de todos los pacientes diagnosticados y tratados por carcinoma escamoso de orofaringe, hipofaringe y laringe en el Servicio de Otorrinolaringología del Hospital San Juan de Dios entre enero de 2006 y diciembre de 2007. Resultados: El 55,5 por ciento presentó una función tiroidea alterada en la evaluación posterior al tratamiento. La modalidad de tratamiento es crucial, variando de 35 por ciento de alteración en el grupo tratado con radioterapia v/s 83 por ciento de afección cuando ésta se asoció a cirugía. La quimioterapia no mostró efectos. Conclusiones: El hipotiroidismo es una complicación frecuente, pero poco reconocida, que ocurre en más del 50 por ciento de los pacientes tratados por cáncer de orofaringe, hipofaringe y laringe.

Introduction: Hypothyroidism is a complication of head and neck cancer treatment, it incidence goes from 7 percent to 57 percent. Aim: To estímate frequency of hipothyroidism in patients with cáncer ofpharynxand larynx and to dertermine factor of risk. Material and method: Transversal study Thyroid function measurement in patients diagnosed and treated for oropharyngeal, hypophariyngeal and laryngeal squamous cell carcinoma at San Juan de Dios's Hospital since January 2006 to December 2007. Results: 55,5 percent presented an altered thyroid function after treatment. The treatment modality is crucial, on it's frequency, changing from 35 percent with radiotherapy, v/s 83 percent when this one was associated with surgery. The chemotherapy did not show effects. Conclusions: The hypothyroidism is a frequent, but slightly recognized complication, which happens in more than 50 percent of patients treated for for oropharyngeal, hypophariyngeal and laryngeal squamous cell carcinoma.

Management of parapharyngeal space tumours

To determine the role of clinical features, fine needle aspiration cytology [FNAC] and computed tomography [CT] scan in diagnosing parapharyngeal space [PPS] tumors and treatment options. A descriptive study. From July 2000 to July 2002 at Pakistan Institute of Medical Sciences, Islamabad. Patients diagnosed as having PPS tumors were studied. The medical record of patients was reviewed for their age, gender, clinical features, investigations [FNAC and CT scan] and treatment. The mean age, percentage of different clinical features and the sensitivity and specificity of FNAC was determined. The mean age of patients presenting with PPS tumours was 33.6 years. The most common clinical features were neck mass [93%] and bulge in lateral pharyngeal wall [80%]. The CT scan showed exact location and extent of tumour in 11 out of 15 cases. The sensitivity and specificity of FNAC was 70% and 85% respectively. The most common tumours were neurogenic tumours [6] and salivary gland tumours [4]. Surgery was performed in all except 2 patients with lymphoma in whom radiation and chemotherapy was recommended. This study indicates that PPS tumours are usually benign neurogenous and salivary gland tumours presenting with neck mass and bulge in oropharynx. FNAC and CT scan are important in diagnostic work up and treatment planning. Surgery has the best results in most cases

Diagnostico e tratamento do cancer da faringe / Diagnosis and treatment of pharyngeal cancer

As afeccoes malignas das tres regioes da faringe - nasofaringe, orofaringe e hipofaringe - sao bastante distintas entre si no que diz respeito ao quadro clinico e ao tratamento. Enquanto na nasofaringe os tumores sao menos diferenciados e tratados principalmente pela radioterapia, os tumores da orofaringe e da hipofaringe sao mais diferenciados e, como regra, respondem melhor a terapeutica cirurgica associada a radioterapia pos-operatoria. Na terapeutica dos tumores da faringe, os linfonodos cervicais devem ser tratados pelo esvaziamento cervical e / ou pela radioterapia

Parapharyngeal space tumours, clinical presentation, diagnosis and management

A series of 6 cases of Parapharyngeal space tumours is reported. Of the total, 4 [66%] were benign schwanomas. The incidence of malignant tumours in this study is 33%. The commonest mode of clinical presentation was painless mass in the lateral wall of pharynx with or without a contagious swelling below the angle of mandible. Pain, trismus and cranial nerve palsies indicated malignancy. Amongst the investigations M.R.I. is of special interest. In case No. 5 cross-circulation in angiograms helped us in deciding to simultaneously ligate both internal and external carotids. This has been done in some series published elsewhere but not in Pakistan
