What does this research mean for the field?

On CT scans of lung cancer patients, obliteration of the superior pulmonary vein is a highly reliable indicator of intrapericardial tumor extension, whereas obliteration of the inferior pulmonary vein is not. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Implication

Superior pulmonary vein obliteration on CT may inform surgical planning in lung cancer; hypothesis-generating and requires prospective validation.

Structured PICO

Does obliteration of the pulmonary vein on preoperative CT predict intrapericardial extension of lung cancer?

Population

325 patients who underwent thoracotomy for primary lung cancer, with a focus on 19 patients whose preoperative CT scans showed obliteration of the pulmonary vein up to its entrance into the left atrium without filling defect in the left atrium.

Intervention

Preoperative CT assessment of pulmonary vein obliteration (superior vs. inferior).

Outcome

Intrapericardial extension of tumor through the pulmonary vein beyond the pericardial reflection, as confirmed by surgical records.surrogate

Obliteration of the superior pulmonary vein on CT is a highly reliable indicator of intrapericardial extension in lung cancer, whereas inferior pulmonary vein obliteration is less reliable.
