Role of Limited Sublobar Resection for Early-Stage Lung Cancer: Steady Progress
Menée à partir de données portant sur 624 patients atteints d'un cancer du poumon de stade I (durée médiane de suivi : 5,4 ans), cette étude compare, du point de vue de la récidive et de la survie globale, l'efficacité d'une segmentectomie anatomique et d'une lobectomie
The operative modes for pulmonary parenchymal resection include pneumonectomy, bilobectomy, lobectomy, segmentectomy, and wedge resection, according to the volume of lung parenchyma to be resected. From a technical viewpoint, with respect to the pulmonary hilum, these can be divided into nonanatomic (wedge resection) and anatomic (all other) resections. The characteristic feature of anatomic resections is that the parenchymal extent of resection is automatically determined according to the bronchovascular anatomy of
the lung. For segmentectomy and wedge resection, the term sublobar resection is sometimes used. However, although sublobar resection is used to describe both approaches, both the segmental bronchus and pulmonary artery are divided at the hilumin segmentectomy, whereas in wedge resection, the extent of resection is arbitrarily determined in relation to the location of the target lesion, and the hilum remains intact. The term limited resection is also used as opposed to the term standard resection, which is essentially at least lobectomy with hilar and mediastinal lymph node sampling/dissection. Therefore, the present-day limited resection inevitably indicates sublobar resection...
