Though there are no evidences that postoperative therapy improves overall survival (OS) in stage I-II endometrial carcinoma, many women receive radiation or chemotherapy. This study aimed to investigate the baseline risk of recurrence after complete resection without any adjuvant therapies and suppose validity for carcinoma.Charts patients with carcinoma who underwent operation between January 2005 December 2011 were retrospectively reviewed prognosis assessed. Risk classifications performed...

Abstract Background In breast cancer patients receiving neoadjuvant chemotherapy (NAC), immediate reconstruction (IBR) as a treatment option remains controversial. We assessed the impact of NAC on surgical and oncological outcomes undergoing IBR. Methods This was retrospective multicenter study 4726 cases The rate postoperative complications survival data were compared between IBR who received those did not receive NAC. Propensity score matching analysis performed to mitigate selection bias...

Radar-based microwave imaging is a promising technique for multiple medical applications, such as breast health monitoring, cancer detection, ablation and chemotherapy monitoring. In our previous work, hand-held multistatic CMOS impulse-radar detector was developed. It designed to be placed directly on the patient in supine position without coupling medium. radar-based imaging, surface clutters, which are generated from skin reflection, imperfect contacts, antenna coupling, deteriorate...

Mammography screening has increased the detection of subcentimeter breast cancers. The prognosis for estrogen receptor (ER)-positive and human epidermal growth factor 2 (HER2)-negative T1a/bN0M0 cancers is excellent; however, necessity adjuvant endocrine therapy (ET) uncertain. We evaluated effectiveness ET in patients with ER-positive HER2-negative cancer who underwent surgery from 2008 to 2012. Standard was administrated after surgery. primary endpoint cumulative incidence distant...
