Abstract

Introduction

In breast cancer, recommendations for axillary surgery are currently shifting toward omitting SLNB. Studies have shown that not performing axillary staging has no impact on regional control or survival and translates into improved quality of life. We sought to determine whether certain clinical factors such as tumor size or type, immunohistochemical characteristics, tumor grade or Ki-67 value are predictive of metastatic disease in the lymph nodes.

Methods

A retrospective observational study was conducted of patients who underwent breast cancer surgery during the years 2019-2024. Inclusion criteria were: tumor size equal to or less than 2 cm as measured by ultrasound, and axilla that was clinically and ultrasound-negative.

Results

One hundred and fifty-six breasts were operated on, with a mean age of 64.5 years. Regarding immunohistochemistry, tumor grade, and age, no differences were observed. However, patients with tumors > 2 cm and lobular tumors did have greater lymph node involvement (p < 0.05).

Conclusions

There are no variables that predict lymph node involvement before surgery. Today, we are not prepared to lose the information provided by SLNB, and part of the postoperative treatment is determined by its results.

乳腺癌腋窝病变预测值

在乳腺癌中，腋窝手术的建议目前正在转向省略SLNB。研究表明，不进行腋窝分期对局部控制或生存没有影响，并转化为生活质量的提高。我们试图确定某些临床因素，如肿瘤大小或类型、免疫组织化学特征、肿瘤分级或Ki-67值是否可预测淋巴结转移性疾病。方法对2019-2024年接受乳腺癌手术的患者进行回顾性观察研究。纳入标准：超声测量肿瘤大小等于或小于2cm，临床及超声阴性腋窝。结果本组手术156例，平均年龄64.5岁。在免疫组化、肿瘤分级和年龄方面，没有观察到差异。然而，肿瘤>； 2 cm和小叶肿瘤患者确实有更大的淋巴结累及（p < 0.05）。结论术前没有预测淋巴结受累的变量。今天，我们不准备失去SLNB提供的信息，部分术后治疗取决于其结果。
