Prediction of subpectoral direct-to-implant breast reconstruction failure based on random forest and logistic regression algorithms: A multicenter study in Chinese population.

Background: Few studies have been conducted on direct-to-implant (DTI) breast reconstruction failure, and consistent conclusions are lacking. Thus, this study aimed to comprehensively analyze the risk factors of reconstruction failure.

Methods: Patients who underwent DTI breast reconstruction after mastectomy at a single center between July 18, 2014, and January 13, 2020, were retrospectively included in this study.

Fibromatosis-like metaplastic carcinoma of the breast: Two case reports.

Background: Fibromatosis-like metaplastic carcinoma is classified as a rare type of metaplastic carcinoma of the breast by the 2012 WHO pathological and genetic classification criteria for breast tumors, which takes hyperplastic spindle cells as the main component and is often misdiagnosed as benign stromal proliferative lesions or benign mesenchymal tumors of the breast because of its mild morphology. Here, we collected the clinical data of 2 cases of fibromatosis-like metaplastic carcinoma of the breast and performed pathomorphological observation and immunohistochemical staining of the surgically resected specimens. According to the clinical features, imaging features, immunophenotype, diagnosis and differential diagnosis of 2 cases of fibromatosis-like metaplastic carcinoma of the breast, it was further differentiated.

Tc-labeled sodium phytate and stannous chloride injection accurately detects sentinel lymph node in axillary of early stage breast cancer: a randomized, controlled study.

Aim: The aim of this study was to assess the sentinel lymph node (SLN) detection rate and accuracy of Tc-labeled sodium phytate and stannous chloride (Tc-PHY) injection versus Tc-labeled sulfur colloid (Tc-SC) injection in sentinel lymph node biopsy (SLNB) in patients with early stage breast cancer.

Methods: A total of 146 consecutive female patients with early stage breast cancer were recruited in this open-labeled, randomized, controlled study. SLNB was conducted on all patients, and Tc-PHY or Tc-SC was used as the radioactive agent (RA).
