BACKGROUND: The objective of this study was to determine whether cyclooxygenase-2 (COX-2) overexpression was an indicator of prognosis in patients with International Federation of Gynecology and Obstetrics (FIGO) Stage IIB uterine cervical carcinoma who underwent radiation and concurrent chemotherapy. METHODS: Seventy-five patients with FIGO Stage IIB squamous cell carcinoma (SCC) of the uterine cervix who were treated with radiotherapy and concurrent chemotherapy between 1991 and 1996 were divi

OBJECTIVE: The aim of this study was to identify the comprehensive risk factors for lymphedema, thereby enabling a more informed multidisciplinary treatment decision-making. SUMMARY BACKGROUND DATA: Lymphedema is a serious long-term complication in breast cancer patients post-surgery; however, the influence of multimodal therapy on its occurrence remains unclear. METHODS: We retrospectively collected treatment-related data from 5549 breast cancer patients who underwent surgery between 2007 and 2

ClinicalTrials.gov Identifier: NCT04803266.

Purpose: Radiation pneumonitis (RP) is one of the most severe toxicities experienced by patients with breast cancer after radiotherapy (RT). RT fractionation schemes and techniques for breast cancer have undergone numerous changes over the past decades. This study aimed to investigate the incidence of RP as a function of such changes in patients with breast cancer undergoing RT and to identify dosimetric markers that predict the risk of this adverse event. Methods and Materials: We identified 18

Integrin-linked kinase (ILK) is involved in signal transduction by integrin-mediated cell adhesion that leads to dynamic actin reorganization. Actin (de)polymerization is regulated by cofilin, the Ser(3) phosphorylation (pS(3)cofilin) of which inhibits its actin-severing activity. To determine how ILK regulates pS(3)cofilin, we examined the effects of ILK on pS(3)cofilin using normal RIE1 cells. Compared with suspended cells, fibronectin-adherent cells showed enhanced pS(3)cofilin, depending on

Apoptotic cell clearance by phagocytes is essential in tissue homeostasis. We demonstrated that conditioned medium (CM) from macrophages exposed to apoptotic cancer cells inhibits the TGFβ1-induced epithelial–mesenchymal transition (EMT), migration, and invasion of cancer cells. Apoptotic 344SQ (ApoSQ) cell-induced PPARγ activity in macrophages increased the levels of PTEN, which was secreted in exosomes. Exosomal PTEN was taken up by recipient lung cancer cells. ApoSQ-exposed CM from PTEN knock

Formation of ultrathin oxide layer in water‐based processes, resulting in hydroxyl group termination, is an essential process technology for high‐k dielectric stack formation with atomic layer chemical vapor deposition (ALCVD) layers. A silicon(100) surface treated in water vapor in the temperature range of typical ALCVD processes has been studied by high‐resolution X‐ray photoelectron spectroscopy (HRXPS) analysis. cleaned silicon (100) surface is stable in water vapor up to . From , the surfac

PURPOSE: To review the clinical outcomes of extended-field radiation therapy (EFRT) and to analyze prognostic factors significant for survival in patients receiving EFRT for uterine cervical carcinoma with para-aortic node (PAN) metastasis. PATIENTS AND METHODS: We retrospectively reviewed 90 patients with stage IB-IVA cervical cancer and PAN metastasis between 1987 and 2012. Median age was 50 (range, 24-77). Patients received median 70.2 Gy (range, 56-93) to point A and median 50.4 Gy (range, 4

We report a case of aggressive 'nasal type' natural killer (NK)/T cell lymphoma initially presenting as a testicular tumor in a Korean man, which quickly took a fatal course by widespread dissemination. Histologically, the testicular mass showed a diffuse dense infiltrate of medium-sized and atypical large lymphoid cells with angiocentric and angiodestructive infiltration and areas of coagulative necrosis on hematoxylin-eosin stained sections. Immunophenotyping by immunohistochemistry yielded su
