Resultados del tratamiento quirúrgico de las metástasis ganglionares en pacientes con carcinomas escamosos cutáneos de cabeza y cuello

Introduction

Out of all cutaneous squamous cell carcinomas originating in the head and neck (HNCSCC), 2%-4% are associated with parotid or cervical lymph node metastasis. The aim of this study is to analyse the prognostic factors of patients with HNCSCC with lymph node involvement treated surgically. Additionally, we aim to compare the prognostic capacity of the classification of these patients according to the 8th edition of the TNM, and an alternative classification proposed by O’Brien et al.

Patients and methods

Retrospective review of 65 patients with HNCSCC with lymph node metastasis treated surgically during the period 2000-2020.

Results

During the study period we carried out 13 neck dissections and 52 parotidectomies + neck dissection in patients with lymph node metastases from a HNCSCC. The great majority of patients (89.2%) received post-operative radiotherapy. The 5 year disease-specific survival was 69.9%, and the overall survival it was 42.8%. The classification proposed by O’Brien et al., based on the parotid or cervical location of the lymph node metastases, and the size and number of the metastatic lymph nodes, had a better prognostic capacity than the TNM classification.

Conclusions

The surgical treatment of lymph node metastases in patients with HNCSCC achieved a high disease control. The classification based on the location, size and number of lymph node metastases proposed by O’Brien et al. had better prognostic capacity than the TNM classification.
