During radiotherapy sessions to treat brain tumors or head-and-neck cancers, some patients experience unusual visual and/or olfactory perceptions. This prospective study sought answer two questions: (i) what proportion of these unpleasant sensations?, and (ii) which organs are responsible? Eligible had near-orbital treated by helical tomotherapy. All were aged 10 years older, able communicate, interviewed a radiation oncologist at least once weekly during therapy. If they experienced such...
We first used MucoUp®, a hyaluronic acid in endoscopic resection, as spacer brachytherapy. In five cervical cancer patients, MucoUp® insertion increased 90% dose of the high-risk CTV to over 80 Gy while decreasing organs at risk. No related adverse events were observed.
Abstract Objective To determine the most appropriate radiologic criteria of metastatic retropharyngeal lymph nodes (RLNs) in patients with maxillary sinus cancer (MSC). Materials and methods We retrospectively evaluated 16 consecutive who underwent magnetic resonance imaging (MRI) before after treatment locally advanced squamous cell carcinoma sinus. The minimal maximal diameters all RLNS were recorded. RLNs classified as on basis MRI follow-up (f/u). considered non-metastatic if stable...
Abstract Background The aim of this study was to evaluate the long-term treatment results combined superselective intraarterial chemotherapy and radiation therapy for advanced maxillary sinus cancer (MSC) incidence regional lymph node failure, reveal clinical anatomical predictive factors metastasis. Methods We retrospectively evaluated 55 consecutive patients with locally squamous cell carcinoma who were treated external radiotherapy chemotherapy. Elective nodal irradiation (ENI) performed...
Analyzing dose distributions to regional lymph-node metastases (RLNMs) in locally advanced cervical cancer (LACC) patients undergoing intracavitary and interstitial hybrid brachytherapy (IC/IS).
Studies on the clinical outcomes of radiotherapy for (c)T1aN0M0 (UICC-TNM Classification, Eighth Edition) esophageal cancer (EC) are limited. Therefore, this retrospective study aimed to clarify definitive (RT) or chemoradiotherapy (CRT) cT1aN0M0 EC unsuitable endoscopic resection and surgery.Patients with squamous cell carcinoma who underwent RT CRT between January 2009 December 2020 were retrospectively reviewed. The initial response, toxicities, survival rates, recurrence patterns,...
動注化学放射線療法を行った進行上顎洞扁平上皮癌55症例を対象に，画像上ルビエールリンパ（Rp）節転移頻度とRp領域照射線量について遡及的に検討した。治療前画像再評価によりRp節転移は10例（18％）で認め，9例は短径5mm以上，1例は長径10mm以上の基準で診断した。MRIまたはPET-CT施行症例はRp節転移頻度が高い傾向があった（P＝0.090）。10例のRp節転移照射線量の中央値は57.7 Gyで，8例で標的設定を行わずとも高線量が照射され，Rp節再発は1例も認めなかった。強度変調放射線治療時にRp領域を標的設定しない場合，3次元放射線治療に比べRp領域線量は有意に低下した（47.4 Gy対36.0 Gy，p＝0.040）。

Abstract We conducted a prospective study to quantitatively evaluate the movement of chest wall establish simple and reproducible deep-inspiration breath-hold (DIBH) method. The left nipple position was monitored confirm inspiratory state. Planning computed tomography (CT) performed under DIBH free-breath. radiation plans with free-breath CT evaluated organ at risk (OAR) target doses according two different plans. relationship between positioning errors patient factors using univariate...
External-beam radiation therapy (EBRT) for differentiated thyroid cancer has been controversial. Palliative irradiation is usually recommended patients with treatment-resistant relapse and/or distant metastases, but high-dose EBRT not often indicated in this situation. A 50-year-old man had recurrence of an inoperable cervical mass and multiple lung metastases after total thyroidectomy neck dissection. Because the patient good performance status no other life-threatening he received...

Radiotherapy (RT) has been rarely reported as a cause of tumor lysis syndrome (TLS). Therefore, the patient characteristics and details RT-induced TLS remain unclear, which may delay diagnosis. Herein, we report case palliative severe in with multiple myeloma (MM) skin involvement along literature review.A 75-year-old female MM was referred to our department February 2021 because swelling pruritus bulky on her right breast left leg pain. She had received chemotherapies autologous peripheral...
乳癌術後放射線治療後経過観察中に同側乳房内再発を来し，追加乳房切除術施行予定となった58歳女性と冠動脈バイパス術後経過観察中に両側肺癌を指摘された81歳男性に対しがんの全身検索目的でDWIBS（diffusion weighted imaging with background signal suppression：背景抑制広範囲拡散強調画像）を施行した。その結果，両症例とも二次的に膀胱癌が発見され，適切な治療につながった。いずれの症例もPET/CTでは発見困難な病変であった可能性が高く，少なくとも本症例ではがんの全身検索としてDWIBS がPET/CTに比して有用であったと考えられるので報告する。
