Evaluation of lymph nodes during lung cancer resection is essential for pathologic staging and adjuvant treatment decisions. We developed a standardized approach for grossing resected lobes and segments to better assign the N1 category to hilar and peripheral lymph nodes. Lung specimens were dissected centrifugally from the bronchial stump, and all lymph nodes at the segmental and subsegmental bifurcations were removed. When combined with mediastinal lymph node dissection, this approach will likely maximize the number of lymph nodes analysed and improve the accuracy of pathologic N descriptor classification.
肺癌切除术中评估淋巴结对于病理分期和辅助治疗决策至关重要。我们开发了一种标准化的方法来对切除的肺叶和肺段进行大体检查，以便更好地将N1类别分配到肺门和周围淋巴结。从支气管残端向心性解剖肺标本，并切除段和亚段分叉处的所有淋巴结。当与纵隔淋巴结清扫相结合时，这种方法可能会使分析的淋巴结数量最大化，并提高病理N描述符分类的准确性。
