This nationwide, multicenter study investigated treatment outcomes as well the optimal radiotherapeutic strategy in patients with hepatocellular carcinoma (HCC) and portal vein tumour thrombosis (PVTT).We retrospectively reviewed records of 985 who received radiotherapy (RT) for PVTT. The median equivalent RT dose was 48.75 Gy. Combined treatment, defined liver-directed treatments performed within a month RT, administered to 657 (66.7%). PVTT primary were irradiated 413 (41.9%), only...
We aimed to assess prognostic value of metastatic pelvic lymph node (mPLN) in early-stage cervical cancer treated with radical surgery followed by postoperative chemoradiotherapy. Also, we sought define a high-risk group using prognosticators for recurrence.A multicenter retrospective study was conducted the data from 13 Korean institutions 2000 2010. A total 249 IB-IIA patients factors were included. evaluated distant metastasis-free survival (DMFS) and disease-free (DFS) relation...
PurposeEmerging data suggest that higher radiation doses in post-mastectomy radiotherapy may be associated with an increased risk of reconstruction complications. This study aimed to validate previous findings regarding the impact dose on complications among women breast cancer using a multi-center dataset.MethodsFifteen institutions participated, and who received after either autologous or prosthetic were included. The primary endpoint was major post-radiation therapy requiring re-operation...
The General Rules for the Study of Primary Liver Cancer was published in June 2001 as first edition. Since then, 5th edition by 17th Committee Korean Association based on most recent data. ranged over numerous topics such anatomy, medical assessment patients, staging hepatocellular carcinoma, description image findings, summary hepatic resection, surgical specimens, liver transplantation, reporting pathological examinations specimen, non-surgical treatment, radiotherapy, and tumor response...
Purpose There is limited data on radiotherapy (RT) for hepatocellular carcinoma (HCC) in patients with Child-Pugh classification B (CP-B). This study aimed to evaluate the treatment outcomes of fractionated conformal RT HCC CP-B. Materials and Methods We retrospectively reviewed CP-B treated between 2009 2014 at 13 institutions Korea. was diagnosed by Korea guideline 2009, modern techniques were applied. Fraction size ≤ 5 Gy biologically effective dose (BED) ≥ 40 Gy10 (α/β = 10 Gy). A total...
Abstract Objective Hypofractionated radiotherapy has recently been applied to treat pulmonary metastases of hepatocellular carcinoma. However, there is no definite evidence on its safety and efficacy. We evaluate the clinical outcomes hypofractionated for oligo carcinoma in multicenter retrospective study. Methods From March 2011 February 2018, 58 patients with fewer than five who underwent nine tertiary university hospitals were analyzed retrospectively. The primary endpoint was local...
Background and Objectives: Ultra-central (UC) lung tumors are defined as those abutting the proximal bronchial tree. Stereotactic body radiation therapy (SBRT) for UC is difficult because of concerns about severe toxicities. Therefore, we report safety efficacy moderate-intensity SBRT at our institution. Materials Methods: From January 2017 to May 2021, treated 20 patients with a dose 45–60 Gy in 10 fractions. The primary endpoints were local control (LC) overall survival (OS). Results:...
Quality of life (QoL) has become a major concern as the survival time breast cancer increases. We investigated changes in QoL through comprehensive categorical analysis, for first three years after treatment including radiotherapy. A total 1156 patients were enrolled from 17 institutions. All survivors grouped according to surveillance period 9–15 months (first year), 21–27 (second and 33–39 (third year) end The 5-dimensional questionnaire by EuroQol group (EQ-5D) EORTC Life Questionnaire;...
Background This study was to assess the rate of radiotherapy (RT) utilization according modality in South Korea identify implications contemporary RT patterns. Methods We collected information from claims and reimbursement records National Health Insurance Service 2010 2019. classified location each institution as capital (Seoul, Incheon, Gyeonggi-do) non-capital areas. Results The total cancer patients nationwide 24.5% 2010, which consistently has increased 36.1% 2019 (annual increase...
PurposeThis study evaluated the influence of prognostic factors and whole brain radiotherapy (WBRT) on overall survival (OS) breast cancer (BC) patients with metastases (BM).Methods materialsMedical records 730 BC diagnosed BM from 2000 to 2014 at 17 institutions were retrospectively reviewed. OS was calculated diagnosis. Median follow-up duration 11.9 months (range, 0.1–126.2).ResultsMedian 15.0 (95% CI: 14.0–16.9). Patients different BC-specific graded assessment (GPA) scores showed...
We evaluate the feasibility of a concurrent application sorafenib and external beam radiation therapy (EBRT) for advanced hepatocellular carcinoma (HCC). PubMed, Embase, Medline, Cochrane Library were searched up to 9 April 2021. The primary endpoint was grade ≥3 complications, secondary overall survival (OS). Subgroup analyses performed studies with EBRT targets, intrahepatic vs. non-intrahepatic lesions (e.g., extrahepatic metastases or malignant vessel involvement only). Eleven involving...
Background: This study aimed to assess the recent changes of radiation therapy (RT) modalities in Korea.In particular, we focused on intensity-modulated (IMRT) utilization as main index, presenting application status advanced RT. Methods: We collected information from Korean Health and Insurance Review Assessment Service data based National claims reimbursements records by using treatment codes 2010 2016.We classified locating region each institution capital vs. non-capital areas...
Purpose: Lymph node metastasis of hepatocellular carcinoma is categorized as advanced in Barcelona Clinic Liver Cancer staging, and sorafenib a sole treatment recommended. However, appliance local including external beam radiotherapy (EBRT) has not been uncommon. We performed meta-analysis systemically reviewed current literature to evaluate the efficacy safety EBRT. Methods: PubMed, Medline, Cochrane library, Embase were searched until December 17, 2017. The primary endpoint analyses was...
