ABSTRACT
Abstract

Introduction:

Parotid carcinomas have varying histological types and diverse biologic behaviors. Establishing an adequate treatment plan and predicting recurrence is important.

Objective:

To analyze the risk factors associated with recurrence in our 5 year experience with 30 cases of primary parotid carcinoma undergoing surgery at a single institute.

Methods:

From January 2009 to December 2013, 30 patients with surgical treatment of parotid carcinoma were identified based on their medical records.

Results:

The 30 patients were comprised of 17 males and 13 females. Among 11 patients with T4 tumors, seven patients had recurrence. Among seven patients with cervical nodal metastasis, all patient except one had recurrence. Clinically late stages (stage III and IV) showed more common recurrence than early stage (stage I and II) lesions. Lymphovascular invasion was seen in 5 patients, and all patients had recurrence. Among 11 patients with extracapsular spread, 7 patients had recurrence. In 17 patients with high grade carcinomas, ten patients had recurrence. In 13 patients with low grade carcinomas, no patients experienced recurrence.

Conclusion:

T- and N-stage, clinical stage, lymphovascular invasion, extracapsular spread, and histopathologic grade correlate significantly with recurrence in parotid carcinoma.
RESUMO
Resumo

Introdução:

Os carcinomas da parótida têm diferentes tipos histológicos e comportamentos biológicos diversos. O estabelecimento de um plano de tratamento adequado e a previsão de recorrência são muito importantes.

Objetivo:

Analisar os fatores de risco associados à recorrência em nossa experiência de cinco anos com 30 casos de carcinoma parotídeo primário submetidos a cirurgia em uma única instituição.

Método:

De janeiro de 2009 a dezembro de 2013, 30 pacientes com tratamento cirúrgico de carcinoma parotídeo foram identificados com base nos prontuários.

Resultados:

Entre os 30 pacientes, 17 eram homens e 13, mulheres. Dos 11 pacientes com tumores T4, sete apresentaram recorrência. Entre sete pacientes com metástase em linfonodo cervical, todos, exceto um, apresentaram recorrência. Lesões em estágios clínicos tardios (III e IV) apresentaram recorrência mais comumente do que as dos estágios iniciais (I e II). A invasão linfovascular foi observada em cinco pacientes e todos os cinco apresentaram recorrência. Entre 11 pacientes com disseminação extracapsular, sete apresentaram recorrência. Dos 17 pacientes com carcinomas de alto grau, dez apresentaram recorrência. Em 13 pacientes com carcinomas de baixo grau, nenhum apresentou recorrência.

Conclusão:

Estágios T e N, estágio clínico, invasão linfovascular, disseminação extracapsular e grau histopatológico correlacionam-se de maneira significante com recorrência do carcinoma de parótida.
