Background Although several prospective studies have reported the efficacy of stereotactic body radiotherapy (SBRT) for hepatocellular carcinoma (HCC), treatment‐related toxicity varies and has not been determined. Therefore, authors evaluated safety SBRT patients with HCC in a hepatitis B virus‐endemic area. Methods This multicenter phase 2 trial enrolled unresectable HCC. Patients received 45 to 60 Gy 3 fractions. To evaluate gastroduodenal toxicity, esophagogastroduodenoscopy (EGD) was...
Objectives The Impact of Optimism, Gratitude Disposition, Social Support, and Major Satisfaction on Subjective Well-being among Nursing Students Methods This study aims to investigate the relationships between optimism, gratitude disposition, social support, major satisfaction, subjective well-being nursing students in B City. By identifying factors influencing these students' well-being, seeks provide foundational data for intervention programs aimed at enhancing positive living students....
The purpose of the current in silico planning study is to compare radiation doses whole-breast irradiation (WBI) and plus regional lymph node (WBI+RNI) administered nodes (RLN) pN1 breast cancer. Twenty-four participating institutions were asked create plans WBI WBI+RNI for two dummy cases. To target coverage between participants, an isodose line equal 90% prescribed dose was converted contour (contour90% iso). relative nodal (RND) obtained using ratio RLN dose. Fleiss’s kappa values which...
In a recent meta-analysis, post-mastectomy radiotherapy (PMRT) reduced any first recurrence (AFR) and improved survival in N1 N2 patients. We investigated risk factors for AFR after optimal systemic therapy without PMRT, to define subgroup of patients who may benefit from PMRT.One thousand three hundred eighty-two pT1-2N1M0 breast cancer treated with mastectomy PMRT between 2005 2010 were retrospectively analyzed. Only 0.6% had no therapy.After median follow-up 5.9 years, there 173 (53...
We conducted this study to investigate the prognosis and failure pattern after breast-conserving treatment (BCT) in patients with occult breast cancer (OBC) negative magnetic resonance imaging (MRI) (MRI-OBC). Survival rates patterns 66 who received axillary lymph node dissection (ALND) BCT for MRI-OBC between 2001 2013 at seven hospitals were analyzed. OBC was defined as adenocarcinoma (ALN) +/- supraclavicular (SCN) or internal mammary (IMN) a MRI. Fifty-four had only ALN metastasis (ALN...
We aimed to analyze contemporary practice patterns in breast cancer radiotherapy (RT) and assess longitudinal changes over five years Korea.In 2022, a nationwide survey was conducted among board-certified radiation oncologists. The consisted of 44 questions related six domains: hypofractionated (HypoFx) whole RT, accelerated partial RT (APBI), regional nodal irradiation (RNI), for ductal carcinoma situ (DCIS), postmastectomy (PMRT), tumor bed boost.Seventy oncologists from 61 (out 101; 60%)...
The aim of this study is to compare the treatment outcomes breast conserving surgery (BCS) plus radiotherapy (RT) versus mastectomy for patients with pT1-2N1 triple-negative cancer (TNBC).Using two multicenter retrospective studies on cancer, a pooled analysis was performed among 320 TNBC. All who underwent BCS (n=212) receivedwhole RTwith orwithoutregional nodal RT,while nonewho (n=108)received it. received taxane-based adjuvant chemotherapy. median follow-up periods were 65 months in...
Abstract The aim of the study was to investigate prognostic significance advanced lung cancer inflammation index (ALI) in patients with limited-stage small-cell (LS-SCLC) undergoing definite chemo-radiotherapy (CRT). We included 87 LS-SCLC from South Korea, treated between 2005 and 2019 CRT. ALI calculated using body mass index, serum albumin, neutrophil–lymphocyte ratio. categorized 38 into high group (ALI ≥ 44.3) 48 low < 44.3). Patients exhibited longer overall survival (OS) than...
The purpose of this study was to evaluate local control and survival in patients with spinal metastases who were treated stereotactic body radiotherapy (SBRT) using a CyberKnife, or without prior history irradiation, identify prognostic factors predicting them. Between August 2008 November 2012, 59 metastatic lesions 39 SBRT. Fourteen (23.7%) re-irradiated treat recurrence after radiotherapy. Patients median radiation dose 27 Gy (range, 18-35 Gy) three fractions one five) the CyberKnife...
Adjuvant radiotherapy (RT) is a well-established treatment for breast cancer. However, there large degree of variation and controversy in practice patterns. A nationwide survey on the patterns RT was designed by Division Breast Cancer Korean Radiation Oncology Group. All board-certified members Society were sent questionnaire comprising 39 questions six domains: hypofractionated whole RT, accelerated partial postmastectomy (PMRT), regional nodal ductal carcinoma situ, toxicity. Sixty-four...
The purpose of this study was to evaluate the treatment outcomes radiotherapy (RT) for breast cancer with ipsilateral supraclavicular (SCL) and/or internal mammary (IMN) lymph node involvement.A total 353 patients from 11 institutions were included. One hundred and thirty-six had SCL involvement, 148 IMN 69 both. All received neoadjuvant systemic therapy followed by breast-conserving surgery or mastectomy, postoperative RT whole breast/chest wall. As regional irradiation, given 344 patients,...
Abstract Background Localization of the tumor bed breast cancer is crucial for accurate planning boost irradiation. Lumpectomy cavity and surgical clips provide localizing information about bed. However, defining often difficult because presence unclear lumpectomy lack certain such as absence clips. In present study, we evaluated feasibility initial diagnostic PET-CT in localization using deformable image registration (DIR). Methods We selected twenty-five patients who had an performed...
To evaluate the treatment outcome and prostate-specific antigen (PSA) change after stereotactic body radiotherapy (SBRT) for localized prostate cancer. Patients with cancer treated SBRT at three academic hospitals were enrolled. Treatment was delivered using Cyberknife dose range from 35 to 37.5 Gy in 5 fractions. Biochemical failure (BCF) assessed Phoenix definition toxicities scored Radiation Therapy Oncology Group (RTOG) toxicity criteria. The PSA kinetics analyzed patients who received...
Objectives: The utility of prophylactic central neck dissection (pCND) for papillary thyroid carcinoma (PTC) is still controversial. Although the procedure may reduce locoregional recurrence, it associated with a high rate postoperative complications. aim this study was to evaluate role pCND in patients PTC. Materials and Methods: From January 1995 April 2011, records 477 who underwent total thyroidectomy or without clinically node-negative PTC measuring less than 4 cm were retrospectively...
Introduction This study aimed to investigate the positive rate of human papillomavirus (HPV) and its trend in head neck squamous cell carcinoma (HNSCC) South Korea evaluate clinical differences between HPV-positive -negative tumors. Methods We studied 300 patients with HNSCC arising oropharynx ( n = 77), oral cavity 65), larynx 106), hypopharynx 40), sinonasal 12), treated a tertiary university hospital from January 2008 July 2020. HPV status was determined using p16 immunohistochemical...
Background: Meperidine has proved a far more effective treatment for shivering after spinal anesthesia than equianalgesic doses of opioid agonist.We performed this prospective, double-blinded, randomized study to compare the antishivering effect fentanyl and meperidine when added intrathecal hyperbaric bupivacaine during Cesarean delivery under anesthesia.Methods: Sixty ASA I or II patients undergoing were randomly assigned into three groups.Fentanyl 12.5 ug (group F) mg M) normal saline 2.5...
