Dr Rohit Kumar Jha, Dr Amol Singhal

Abstract :

<p>&nbsp;AIM:&ndash;To assess the outcome of malignant parotid tumor cases operated in our institute and the lessons learnt.</p> <div>MATERIAL &amp; METHODS:- A retrospective observational study of 31 patients presenting with malignant parotid</div> <div>masses were analyzed over 4 years. Patients were investigated, diagnosed and staged according to AJCC 7th edition staging classi􀃶cation</div> <div>and the treatment modality selected on that basis. Postoperatively patients were assessed for complications like facial nerve palsy and</div> <div>Frey‘s syndrome etc. Patients were followed up every 3-6 monthly and their outcomes assessed.</div> <div>RESULTS &amp; DISCUSSION:- Males comprised 61.29%. Most of the patients were in middle age group and main symptom was swelling at</div> <div>parotid site with an average duration of 2.5months. 19.5% of patients had facial palsy at the time of presentation and around 86% of them</div> <div>had high risk features with most of them developing metastasis.78% of patients presented in clinical stage 1 &amp;2. All patients were treated</div> <div>with surgery. Elective neck dissection was done in 11 patients. The most common malignancy found was mucoepidermoid carcinoma</div> <div>(67%). Facial Palsy developed in 12 patients. A Total of 8 patients(25%) developed Freys syndrome which was managed conservatively. 18</div> <div>patients received PORT. The lowest mean disease free survival was seen in high grade mucoepidermoid cancer (9.1mths), while others had</div> <div>almost 2 years of disease free survival. 5 patients developed lung metastasis, With the Mean duration being 20.4 months.</div> <div>Conclusion:-Malignancies of the major salivary glands form a rare and diverse group of cancers.The extent of surgery is dictated by the</div> <div>stage of the tumour which can be super􀃶cial or total parotidectomy. LVI+,PNI+,facial nerve palsy and advanced stage are factors which</div> <div>indicate bad prognosis. Consideration should be given for neck dissection in N+ patients and in N0 neck, if associated with high risk</div> <div>features.</div>
