Grade 1 breast cancer represents the lowest grade of invasive breast cancer and is associated with a low risk of recurrence and distant metastasis. However, when grade 1 breast cancer is associated with lymph node involvement, the prognosis may be worse than that of grade 1 breast cancer without lymph node involvement.
The study population included all patients who were managed in our institution between January 1, 2007 and December 31, 2013 for grade 1 breast cancer . We compared patients who had lymph node involvement to those who had no lymph node involvement.
During the study period 291 grade 1 carcinomas were included of which 23% had associated positive lymph node involvement. Overall survival did not differ significantly between patients without lymph node involvement and those with lymph node involvement, nor was there a significant difference in the risk of local recurrence free survival. However, a significant difference was found in survival without distant metastasis with a significant level of a p at 0.029.
Our findings confirm that tumor size and LVSI are strong predictors of axillary lymph node involvement, which is a key determinant of distant metastasis-free survival.
1 级乳腺癌代表浸润性乳腺癌的最低级别,与复发和远处转移的风险低相关。然而,当 1 级乳腺癌伴有淋巴结受累时,其预后可能比无淋巴结受累的 1 级乳腺癌差。
研究人群包括 2007 年 1 月 1 日至 2013 年 12 月 31 日期间在我院接受治疗的所有 1 级乳腺癌患者。我们将有淋巴结受累的患者与无淋巴结受累的患者进行比较。
在研究期间,共纳入了 291 例 1 级癌,其中 23%有相关的阳性淋巴结受累。无淋巴结受累患者与有淋巴结受累患者的总生存率无显著差异,局部无复发生存率的风险也无显著差异。然而,无远处转移生存率存在显著差异,p 值显著为 0.029。
我们的研究结果证实,肿瘤大小和 LVSI 是腋窝淋巴结受累的强预测因子,而腋窝淋巴结受累是无远处转移生存率的关键决定因素。
