To evaluate the diagnostic accuracy of computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography/computed (PET/CT) in predicting pelvic lymph node (LN) metastases patients with cervical cancer.From January 2009 to March 2015, 114 FIGO stage IA1-IIB uterine cancer who underwent hysterectomy lymphadenectomy took CT, MRI, PET/CT before surgery were enrolled this study. The criteria for LN a diameter ≥1.0 cm and/or presence central necrosis on focally increased...
PurposeTo develop and test a multivariable normal tissue complication probability (NTCP) model predicting lymphedema in patients with breast cancer receiving radiation therapy.Methods MaterialsWe retrospectively reviewed 1345 who received therapy from 2 independent institutions. The were divided into training cohort (institution A, n = 368, all treated 3-dimensional conformal external beam [RT] Gy/fraction) an validation B, 977, either RT or volumetric modulated 1.8-2.0 Gy/fraction 2.67...
To analyze prognostic factors for locoregional recurrence (LRR), distant metastasis (DM), and overall survival (OS) in cervical cancer patients who underwent radical hysterectomy followed by postoperative radiotherapy (PORT) a single institute.Clinicopathologic data of 135 with clinical stage IA2 to IIA2 treated PORT from 2001 2012 were reviewed, retrospectively. Postoperative parametrial resection margin (PRM) vaginal (VRM) investigated separately. The median treatment dosage external beam...
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,...
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...
To generate a map of local recurrences after pancreaticoduodenectomy (PD) for patients with distal extrahepatic cholangiocarcinoma (DEHC) and to evaluate the adequate target volume coverage encompassing majority when clinical (CTV) pancreatic cancer was applied.We retrospectively reviewed records DEHC who underwent had postoperative CT scans acquired between 1991 2015 available. The sites recurrence were delineated on individual scans, then, mapping manually performed onto template images....
A relationship between the axillary-lateral thoracic vessel juncture (ALTJ) dose and lymphedema rate has been reported in patients with breast cancer. The purpose of this study was to validate explore whether incorporation ALTJ dose-distribution parameters improves prediction model's accuracy.A total 1,449 women cancer who were treated multimodal therapies from two institutions analyzed. We categorized regional nodal irradiation (RNI) as limited RNI, which excluded level I/II, vs extensive...
Background: For decades, conventional fractionated whole breast irradiation (CF-WBI) was used after conserving surgery (BCS). Pivotal phase-3 trials on hypofractionated-WBI (HF-WBI) showed its non-inferiority as compared to CF-WBI. However, younger patients are often not treated with HF-WBI. The aim of this multi-centre comparative study is confirm the safety HF-WBI in a real-life series patients.Material and methods: Between 2010 2016, total 786 aged less than 60 years old early-stage...
Background/Aim: We evaluated dosimetric and clinical results of volumetric-modulated arc therapy (VMAT) treating internal mammary nodes (IMNs) in patients with locally advanced breast cancer. Patients Methods: Between July 2012 December 2013, treatment outcomes 31 stage III cancer treated postoperative radiotherapy including the IMN field using VMAT were analyzed. Results: The median follow-up was 25.2 months. showed good homogeneity improved conformity. incidence lung toxicity grade 2 or...
The purpose of this study is to evaluate the treatment outcomes adjuvant radiotherapy using vaginal brachytherapy (VB) with a lower dose per fraction and/or external beam (EBRT) following surgery for patients stage I endometrial carcinoma.The subjects were 43 International Federation Gynecology and Obstetrics (FIGO) cancer who underwent between March 2000 April 2014. Of these, 25 received postoperative VB alone, while 18 EBRT whole pelvis; 3 these treated plus VB. median was 50.0 Gy...
This study aims to investigate the difference of gene expression and its prognostic significance in younger women with melanoma. Significantly upregulated genes tumors compared normal skin tissues were extracted. Among these genes, that significantly affected survival according level selected, pathway annotation was performed. The patient proportion high/low most significant pathways analyzed each age (< 50, 50-59, ≥ 60) gender group. Survival age, gender, pathways. tumor also had impacts on...
To evaluate the CT findings of acute radiation pneumonitis (RP) in breast cancer patients undergoing post-operative radiotherapy, and to analyze clinicodosimetric factors associated with RP.Between 2015 2017, 61 who underwent follow-up chest at 3 months after radiotherapy were analyzed. The degree RP on was evaluated by change extent scoring system (grade 0, no RP; Grade 1, ground-glass opacities (GGOs); 2, GGOs and/or consolidations; 3, clear focal consolidation; 4, dense consolidation)....
To evaluate the role of postmastectomy radiation therapy (PMRT) in patients with node-negative breast cancer 5cm or larger tumors undergoing mastectomy.Medical records 274 from 18 institutions treated mastectomy between January 2000 and December 2016 were retrospectively reviewed. Among these, 202 underwent PMRT, while 72 did not. Two hundred forty-one (88.0%) received systemic chemotherapy, 172 (62.8%) hormonal therapy. Patients receiving PMRT younger, more likely to have progesterone...
Background/Aim: To analyze the prognostic significance of nodal status in patients undergoing preoperative chemoradiotherapy (CRT) followed by curative resection for locally advanced rectal cancer. Patients and Methods: Between 2000 2015, 80 consecutive with cancer underwent CRT resection. The lymph node ratio (LNR) was defined as number positive nodes (LNs) divided examined LNs, log odds (LODDS) between negative LNs. value these indicators evaluated terms overall (OS) disease-free (DFS)...
Background/Aim: To present the variations in target delineation and planning results of intensity-modulated radiation therapy (IMRT) for breast cancers. Patients Methods: We requested volumes organs at risk two cases left cancers, evaluated IMRT plans including supraclavicular internal mammary node irradiation. Results: Twenty-one institutions participated this study. Differences volume among reached up to three-times breast-conserving surgery (BCS) case five-times mastectomy case. Mean...
PurposeTo assess radiation-induced fibrosis (RIF) using shear-wave elastography (SWE) in patients with breast cancer who received radiotherapy (RT) after conserving surgery.MethodsForty-one were enrolled a prospective study before RT. SWE and B-mode ultrasonography performed to measure elasticity. For quantitative measurement, the maximum elasticity value was measured tumor bed non-tumor of treated breast, contralateral RT at 3, 12 months RIF recorded Common Terminology Criteria for Adverse...
