A phase I/II study of intrathecal pemetrexed (IP) combined with involved-field radiotherapy (IFRT) was performed to determine feasibility, safety, and antitumor activity for leptomeningeal metastases (LM) from solid tumors.Participants first received induction IP administration, followed by concomitant within 3 days. The regimen consisted (pemetrexed 10 mg, dexamethasone 5 once per week, 4 times in weeks) IFRT (40 Gy 20 fractions). Six participants were recruited assess feasibility I, then...
Abstract To evaluate the quality of planning target volume (PTV) and organs at risk (OAR) generated by manual Pinnacle (manP) Auto-Planning (AP) modules discuss feasibility AP in application radiotherapy for patients with breast cancer. Thirty who underwent breast-conserving therapy were randomly selected. The Philips 9.10 treatment system was used to design manP PTV OAR distribution on same computed tomography. A physician compared plans terms dosimetric parameters monitor units (MUs) using...
Differences in microstructure can often lead to large differences mechanical properties. Here, the composition, microstructure, and properties of mussel, scallop, ostreidae were researched. And subsequently, three bionic models designed based on microstructures shellfish. Three prepared by printing substrate with light-cured resin filling carbon fiber reinforced epoxy resin. The reinforcement mechanisms also investigated. bending fracture force, compression fracture, impact energy mussels...
Abstract To optimize the collimator angles in dual-arc volumetric modulated arc therapy (VMAT) plans for whole-brain radiotherapy with hippocampus and inner ear sparing (HIS-WBRT). Two sets of VMAT were generated 13 small-cell lung cancer patients: (1) The arcs 1 2 ( θ / ) 350°/10°, 350°/30°, 350°/45°, 350°/60°, 350°/80°, i.e., intersection angle (Δ increased. (2) 280°/10°, 300°/30°, 315°/45°, 330°/60°, Δ = 90°. conformity index CI ), homogeneity HI monitor units (MUs), dosimetric parameters...
Purpose The body contour of patients with cervical cancer is prone to change between radiotherapy sessions. This study aimed investigate the effect changes on setup and dosimetric accuracy radiotherapy. Methods 15 after surgery were randomly selected for retrospective analysis. contours once-per-week cone-beam computed tomography (CBCT) registered planning CT (pCT) subsequent evaluation. A conformity index (CI ) was defined quantify variation changes. volume measured by CBCT collected, its...
This study aimed to evaluate the robustness with respect positional variations of five planning strategies in free-breathing breast hypofractionated radiotherapy (HFRT) for patients after breast-conserving surgery.Twenty who received HFRT 42.72 Gy 16 fractions were retrospectively analyzed. Five treatment utilized each patient, including 1) intensity-modulated radiation therapy (IMRT) (IMRTpure); 2) IMRT skin flash tool extending and filling fluence outside by 2 cm (IMRTflash); 3) target...
Abstract Radiotherapy (RT) is one of the main treatment strategies breast cancer. It challenging to design RT plans that can completely cover target area while protecting organs at risk (OAR). The Plan-IQ feasibility tool estimate best sparing dose OAR before optimizing Plan. A systematic quantitative evaluation quality change intensity-modulated radiation therapy (IMRT) using was performed for modified radical mastectomy in this study. We selected 50 patients with cancer treated IMRT. All...
Purpose The induced radioactivity in stereotactic body radiation therapy with a flattening‐filter‐free 10 MV beam model (10 FFF SBRT) was investigated for the risk to therapists. Methods This study performed on Varian TrueBeam linac. radioisotopes were identified by γ spectroscopy. dose rate from activity measured 12 treatment cycles 4 h continuously. impacts of characteristic factors SBRT investigated, including monitor units (MU), rate, field size, and flattening filter. compared between...
Abstract BACKGROUND The role of involved-field radiation therapy (IFRT) and intrathecal chemotherapy (IC) in leptomeningeal metastasis (LM) from solid tumors was gradually underestimated the era targeted therapy. This study aimed to investigate safety effectiveness concurrent IFRT methotrexate (MTX)/cytarabine (Ara-C) for LM, particularly those who developed LM while receiving METHODS Enrolled patients were randomly assigned two subgroups (IFRT&IC-MTX IFRT&IC-Ara-C), first treated...
Abstract Purpose: Hypofractionated radiotherapy (HypoRT) shows the superiority in cancer treatment because of its high biological equivalent dose. This retrospective study aims to evaluate toxicity and efficacy HypoRT on small cell lung (SCLC). Methods: Medical records SCLC patients between July 2018 October 2019 were collected. All treated with chemotherapy plus (PTV: 30 Gy/10F, PGTV: 45 Gy/10F) eligible for analysis. The was performed a total 4-6 cycles by using Etoposide Cisplatin or...
This study aimed to investigate the dosimetric effect and delivery reliability of jaw tracking (JT) with increasing planning target volume (PTV) for lung stereotactic body radiation therapy (SBRT) plans. A threshold PTV was proposed as a selection criterion between JT fixed-jaw (FJ) techniques. total 28 patients early-stage non-small-cell cancer were retrospectively included. The PTVs ranged from 4.88 cc 68.74 cc, prescribed 48 Gy in four fractions. Three-partial-arc volumetric modulated arc...
Abstract Background and purpose : A systematic quantitative evaluation of the quality change intensity-modulated radiation therapy (IMRT) using Plan-IQ feasibility tool was performed for modified radical mastectomy. Materials methods We selected 50 patients with breast cancer treated IMRT. All received same dose in planning target volume (PTV). Two plans were designed each patient: clinically accepted normal plan group (NP group) repeat (RP group). An automated strategy generated a histogram...
