The Clinical Observation In Scapular Lymph Node Over Axillary Lymph Node Metastasis Of Breast Cancer

Objective : Through the observation of metastasis of the subscapular lymph nodes which location at the intersection of axillary vein and subscapular vessels, by analysis of characteristics of the subscapular lymph nodes in the lymph node metastasis in patients with breast cancer, to lay the foundation to further explore their clinical significance in axillary lymph node metastasis of breast cancer, hoping to furtherguide clinical work.Methods: We collected 60 cases of breast cancer patients who was diagnosed and parallel operation in the first Breast Surgery from March 2015 - January 2017 in Yunnan province tumor hospital. All patients were adopt axillary lymph node dissection, send the axillary lymphatic tissue to pathologic examination, at the same time , separate out the scapular lymph node to pathologic examination, 1 lymph node metastases defined as lymph node positive .According to the scapular lymph node and axillary lymph node metastasis grouping, divided into both positive group (group A),one of the positive (B, D group), both negative (group C), Characteristics of each clinical observation analysis, analysis the clinical features of different groups of the scapular lymph node in the axillary lymph node metastasis. Because of the lacking of group D, we do not discuss.Results: In 60 cases patients, have 3 cases was positive in scapular lymph node,accounting for 5% of the total number of cases; Axillary lymph node metastasis of 27 cases, accounting for 45% of the total number of cases. In patients with positive axillary lymph nodes in the group A and group B, the scapular lymph node positive rate were 0%, 100%, and the corresponding axillary lymph node positive rate was 17.06%,68.63%,it is concluded that the axillary lymph node positive rate is higher,the greater the trend of the scapular lymph node metastasis, But since the sample size is small,can't the exact conclusion, we will increase the sample size to further observe the relationship between the axillary lymph node and the scapular lymph node . Group A, group B and group C of three groups of patients age, menarche age, pregnant times,menopausal status, TNM staging of the tumor, molecular classification, pathological type, the size and the quadrant of the primary tumor,, and whether neoadjuvant chemotherapy in patients ,with various clinical factors in the group, we have not see the obvious differences in the study. We will further increase the sample size to do inquiry.Conclusion: In this study,we can see positive the axillary lymph node rate is higher,the greater the trend of the scapular lymph node metastasis, but since the sample size is small,can't the exact conclusion. Maby there have a particular way which the scapular lymph node are associated with the axillary lymph node metastasis in breast cancer patients, This type of breast cancer patients may have a specific clinical features so that we need further explore the sample size.
