Abstract

Background

No clear consensus has been reached on the indication of supraomohyoid neck dissection (SOHND) for clinically positive lymph-node metastasis.

Patients

Consecutive 100 patients with previously untreated oral cancer treated at Kobe University Hospital were included in this study. All patients were clinically staged as anyTN1M0 and underwent radical dissection of the primary site and level I–V neck dissection as the initial treatment.

Results

None of the 100 patients had pathological lymph-node metastasis (pLN) to level V. pLN to level IV was observed in two patients with tongue cancer in whom clinical lymph-node metastasis was preoperatively observed at level II.

Conclusions

Level V may be excluded in the neck dissection for patients with N1 oral cancers. Level IV dissection should be considered in the patient with tongue cancer and clinical lymph-node metastasis at level II.

临床 N1 口腔癌患者的颈部清扫范围。

摘要

背景

对于临床阳性淋巴结转移的上舌骨颈清扫术 (SOHND) 的适应症尚未达成明确的共识。

耐心

本研究包括在神户大学医院接受治疗的连续 100 名先前未经治疗的口腔癌患者。所有患者临床分期为 anyTN1M0,并接受原发部位根治性切除和 I-V 级颈部清扫作为初始治疗。

结果

100 名患者均未出现病理性淋巴结转移 (pLN) 至 V 级。在 2 名舌癌患者中观察到 pLN 至 IV 级,术前在 II 级观察到临床淋巴结转移。

结论

对于 N1 口腔癌患者,颈部解剖可能排除 V 级。舌癌临床淋巴结转移为Ⅱ级者,应考虑Ⅳ级清扫。
