Oligorrecurrencia a partir de un adenocarcinoma del pulmón: Utilidad de la resección

Non-small cell lung cancer (LC) accounts for 80%–85% of all the varieties of this neoplasm, with adenocarcinoma being the most common histological type.1 The prognosis of this disease is poor due to low survival and high recurrence rates.2 We present here a patient who presented oligo-recurrences during the course of his disease, which were treated surgically. This is a male, 42-year-old smoker investigated due to a lung shadow appearing on an unrelated chest X-ray. Computed tomography (CT) showed central radiodensity 4 cm×2 cm in the upper left lobe, without adenomegalies. Fiber optic bronchoscopy and aspiration cytology gave a diagnosis of epithelial type LC, confirmed by frozen section biopsy during thoracotomy, which was complemented by left upper lobectomy and mediastinal lymphadenectomy (stations 5–7 and 10). The post-operative histopathological result showed predominantly solid, mucin producing, poorly differentiated invasive adenocarcinoma, with no epidermal growth factor receptor overexpression or mutation and metastases in two aortopulmonary window lymph nodes. Treatment was complemented with sequential chemotherapy. Nine months later, the patient presented visual disturbances and vertigo. Magnetic resonance imaging of the head with contrast medium was performed and a single tumor lesion was found in
