Research on the Node Importance of a Weighted Network Based on the K-Order Propagation Number Algorithm

Entropy, 2020
To describe both the global and local characteristics of a network more comprehensively, we propose the weighted K-order propagation number (WKPN) algorithm to extract the disease propagation based on the network topology to evaluate the node importance.

Clinical importance of micrometastasis in sentinel lymph nodes

The Breast, 2011
We evaluated the incidence of micrometastasis and nonsentinel lymph node metastasis as well as local and axillary recurrence rates after level I-II axillary lymph node dissection.Patients (n=760) with early-stage breast cancer underwent sentinel lymph node biopsy, and 45 patients (6.0%) with micrometastasis (0.2-2.0mm) were included in this study.
