As clinical trials of Neutron Capture Therapy (NCT) are initiated in the U.S. and other countries, new treatment planning codes are being developed to calculate detailed dose distributions in patient-specific models. The thorough evaluation and comparison of treatment planning codes is a critical step toward the eventual standardization of dosimetry, which, in turn, is an essential element for ...

Niche construction theory (NCT) explicitly recognizes environmental modication by organisms ("niche construction") and their legacy overtime ("ecological inheritance") to be evolutionary processes in their own right. Here we illustrate how niche construction theory provides usedl conceptual tools and theoretical insights for integrating ecosystem ecology and evolutionary theory. We begin by bri...

BACKGROUND Breast conservation therapy (BCS) after neoadjuvant chemotherapy (NCT) can improve patients' quality of life. Currently used intraoperative examination for negative margins may not be sufficient to detect microresidual foci, which are a risk factor for local recurrence. This study was conducted to investigate the shrinking pattern of breast cancer and residual tumors as a risk factor...

BACKGROUND Corneal biomechanical properties are always compromised after corneal refractive surgeries thus leading to underestimated intraocular pressure (IOP) that complicates the management of IOP. We investigated the changes in postoperative baseline of IOP values measured with noncontact tonometer (NCT), ocular response analyzer (ORA) and corvis scheimpflug technology (CST) in the early pha...

BACKGROUND A pathological complete response (pCR) after neoadjuvant chemotherapy (NCT) is a strong indicator of the benefit of therapy and presents an early surrogate for a favorable long-term outcome. It remains unclear whether Ki-67, a marker for tumor proliferation, can function as a predictor of the response to NCT in breast cancer. The objective of this meta-analysis was to compare the pCR...

PURPOSE The risk for lymphedema (LE) after neoadjuvant chemotherapy (NCT) in breast cancer patients has not been fully understood thus far. This study is conducted to investigate the incidence and time course of LE after NCT. MATERIALS AND METHODS A total of 313 patients with clinically node-positive breast cancer who underwent NCT followed by surgery with axillary lymph node (ALN) dissection...

BACKGROUND Anemia related to adjuvant chemotherapy might predict compromised survival in patients with breast cancer. The present population-based study was to investigate the correlation of pretreatment anemia with pathological response and long-term prognosis of breast cancer patients receiving neoadjuvant chemotherapy (NCT). METHODS From 1999 to 2011, a total of 655 patients with operable ...

Triple-negative breast cancer (TNBC) is an uncommon but aggressive subtype of breast cancer. Obesity has been associated with an increased risk of breast cancer and worse prognosis. Some studies suggest that obese patients are less likely to achieve pathologic complete response (pCR) to neoadjuvant chemotherapy (NCT) and experience worse overall survival. Ki-67 is a proliferation marker that co...

Mục tiêu: Mô tả thực trạng tăng huyết áp (THA) và một số yếu tố liên quan ở người cao tuổi (NCT) tại tỉnh Quảng Bình. Đối tượng phương pháp: Nghiên cứu cắt ngang trên 815 NCT 4 xã thuộc Kết quả: Tỷ lệ THA là 52% trong đó 65,3% đã biết về bệnh 42,4% đang được điều trị. mắc theo (từ 49,5% nhóm 60-69 lên 64,0% từ 80 trở lên) mức BMI 43,2% thiếu cân 59,9% thừa cân); hơn béo bụng (51,4%) so với khôn...

Introduction: We used the TNM staging matched-pair approach to compare the efficacies of surgery after neoadjuvant chemoradiotherapy (NCT), surgery alone and definitive chemoradiotherapy (CCRT) in patients with localized advanced thoracic esophageal squamous cell carcinoma (ESCC). Methods: A total of 642 patients with ESCC from previous studies were studied. Patients whose treatment involved NC...
