Surgical management of breast cancer in China: the Fudan University Shanghai Cancer Center experience

Abstract

We develop a covariant kinetic theory for massive fermions in curved spacetime and external electromagnetic field based on quantum field theory. We derive four coupled semi-classical kinetic equations accurate at O( ), which describe the transports of particle number and spin degrees of freedom. The relation with the chiral kinetic theory is discussed. As an application, we study the spin polarization in the presence of finite Riemann curvature and electromagnetic field in both local and global equilibrium states.

Analysis of factors related to non-sentinel lymph node metastasis in 296 sentinel lymph node-positive Chinese breast cancer patients

“…However, in China, most NSLN-positive patients do not meet those criteria because the ratio of mastectomy is high 7 . We aimed to predict non-SLN metastasis effectively, to reduce the overtreatment ratio in non-SLN-negative patients.…”

“…In the NCCN guidelines for breast cancer, ALND is recommended for patients who do not meet the criteria of the Z0011 or 23-01 trials 29 . However, in China, most NSLN-positive patients do not meet those criteria because the ratio of mastectomy is high 7 . We aimed to predict non-SLN metastasis effectively, to reduce the overtreatment ratio in non-SLN-negative patients.…”

“…In China, because the rate of administering breast-conserving therapy remains low, at approximately 20% 7 , the application of ASCO guidelines for avoiding ALND in patients with positive SLNs remains challenging. Therefore, predicting non-NSLN metastasis has become significantly necessary to screen out extremely low-risk or high-risk patients.…”

“…The American Society of Clinical Oncology (ASCO) guidelines 6 indicate that ALND is not recommended for patients who undergo breast-conserving surgery with total breast radiation therapy and have 1–2 NSLNs containing metastases. In China, because the rate of administering breast-conserving therapy remains low, at approximately 20% 7 , the application of ASCO guidelines for avoiding ALND in patients with positive SLNs remains challenging. Therefore, predicting non-NSLN metastasis has become significantly necessary to screen out extremely low-risk or high-risk patients.…”

Information Dissemination of Public Health Emergency on Social Networks and Intelligent Computation

“…In the past decades, numerous research works have been devoted to social networks [ 3 – 7 ]. Scholars conducted the technologies of content analysis and topic detection to study the information spread path as well as its key nodes [ 4 , 5 ] and furthermore probed into the topological structure and organizational mechanism of the spread network [ 6 – 8 ]. It has been realized that information dissemination in social networks is affected not only by the variable network's structure and dynamically changing spread paths, but also by the complex interactive activities and group behaviors in social communities [ 7 , 8 ].…”
