¿Está justificado hacer un screening a largo plazo para el cáncer de pulmón en los pacientes con un carcinoma de cabeza y cuello?

Abstract

ObjectivePatients with head and neck squamous cell carcinoma (HNSCC) have a higher risk of second lung neoplasms than the general population. The aim of the present study is to evaluate the long-term incidence of second lung malignancies after the diagnosis of a HNSCC and to consider the convenience of the screening for lung cancer in these patients. Material and methodsWe conducted a retrospective study performed on 4,954 patients with an index tumor located in the oral cavity, oropharynx, hypopharynx, or larynx during the period 1985-2017. ResultsDuring the follow-up period 469 patients (9.5%) presented a second pulmonary neoplasm. The incidence of second lung neoplasm was 1.26% per year and remained practically constant throughout the 25-year follow-up period analyzed. According to the results of a multivariate study, male patients, aged between 50 and 80 years, with a history of tobacco use, and with tumors located in the oropharynx or the supraglottis were those with the highest risk of second lung neoplasms. ConclusionPatients with a HNSCC index tumor have a high risk of second neoplasms located in the lung. In order to achieve an early diagnosis of these second neoplasms, it would be advisable to establish screening protocols based on the use of low-dose lung CT, which should be maintained indefinitely during the follow-up period.
