Se revisa la experiencia en 110 casos de nódulo pulmonar solitario (NPS), tratados quirúrgicamente en un período de 10 años, considerando como tal toda lesión pulmonar única, circunscrita y con diámetro inferior a 6cm, rodeada de parénquima sano.

Se ha estudiado la relación de los parámetros siguientes con la malignidad o no del NPS, hallando en todos ellos significación estadística: edad superior a 45 años (p<0,001), sexo (p<0,02), hábito de fumar (p<0,001), manifestaciones clínicas (p<0,001), tamaño de la lesión mayor de 3cm (p<0,02), calcificaciones en el seno del NPS (p<0,01) y cavitación (p<0,001).

Se ha evidenciado que en los 41 pacientes afectos de NPS cuyo origen ha sido un carcinoma broncogénico existía un mínimo de 4 de los factores anteriores. Ello, unido a una mayor supervivencia por parte de este grupo de pacientes con respecto a la media de todas las neoplasias de pulmón intervenidas, aconseja plantear la intervención quirúrgica en los pacientes con varios de los parámetros mencionados que presenten un NPS.

The experience of 110 cases of solitary pulmonary nodule (SPN) who were surgically treated during a 10-year period was reviewed. SPN was defined as any single, well circumscribed lesion of less than 6cm of diameter and sorrounded by normal parenchyma.

The following parameters were correlated with the malignant or nonmalignant character of SPN, and statistical sigificance was found for all of them: age over 45 years (p<0,001), sex (p<0,02), smoking (p<0,001), clinical symptoms (p<0,001), lesion larger than 3cm (p<0,02), calcification within the SPN (p<0,01), and cavitation (p<0,001).

It was found that at least 4 of these factors were present in the 41 patients with SPN due to bronchogenic carcinoma. This fact, together with a higher survival rate after surgery than the mean for all pulmonary neoplasms, suggests that operation should be recommended in all patients with SPN and several of those parameters.
