Background/aim: In prostate cancer, robotic total prostatectomy is a popular treatment modality. However, prostate-specific antigen (PSA) recurrence after prostate cancer surgery remains a concern. Salvage radiotherapy is commonly used to treat PSA recurrence, but the recurrence rate after salvage radiotherapy is high, highlighting the need for better predictive markers.

Radiotherapy plays an important role in the treatment of unresectable lung cancer, and there have been recent developments in the field of radiotherapy for the management of lung cancer. However, to date, there have been few reviews on the improvement in treatment outcomes associated with high precision radiotherapy for lung cancer.

Although there are several studies on the initiation weekday of cancer treatment, there are very few studies in the radiotherapy field. Thus, the present study investigated whether the initiation weekday of radiotherapy affects the local control rate for stage 1 glottic squamous cell carcinoma.

However, the recurrence patterns and therapeutic outcomes after definitive chemoradiotherapy (CRT) are not fully understood. We analyzed survival and prognostic factors associated with post-definitive CRT recurrent EC.

Although immune checkpoint inhibitors have been widely studied for their potential to enhance the AE and improve patient outcomes, findings in cases of head and neck cancers remain limited.
Case Presentation: We report the case of a 72-year-old man who experienced lung oligoprogression during nivolumab treatment for metastatic hypopharyngeal cancer.
Background/aim: Accelerated hyperfractionation (AHF) is used in head and neck cancer to improve the local control (LC) rate, but reports of outcomes for early-stage GC are limited. The outcomes of radiotherapy (RT) for stage 1 glottic carcinoma (GC) were retrospectively analyzed, comparing AHF and once-daily fractionation (ODF) using 2.0-2.

Herein, we report a case in which radiation therapy using the Quad Shot regimen was effective in the treatment of cutaneous metastasis from parotid gland cancer.

We previously reported that total body irradiation (TBI) with ovarian shielding reduces the radiation dose to the ovaries to 2.4 Gy - one-fifth of the dose compared to conventional TBI - and preserves fertility without increasing the risk of relapse.

Drugs that inactivate multiple molecular mechanisms are called multikinase inhibitors (MKIs). Nintedanib is a type of MKI that inhibits downstream cascades in three systems: vascular endothelial growth factor receptor, fibroblast growth factor receptor, and platelet-derived growth factor receptor inhibitions.

Here, we report a case of irreversible paraplegia caused by palliative radiation (20 Gy in 5 fractions) to the spinal cord combined with intrathecal methotrexate (IT-MTX). A 69-year-old man presented with back pain, prompting a diagnosis of acute myeloid leukemia.

However, the radiation dose to the ovaries that preserves ovarian function in TBI remains poorly understood. Furthermore, it is uncertain whether the dose to the shielded organs is associated with relapse risk.

Patients And Methods: Data of 86 patients treated between January 2006 and June 2019 were retrospectively evaluated. The median radiation dose was 64 Gy in 32 fractions.
Mediastinal and hilar lymph node metastasis is one of the recurrence patterns after definitive treatment of lung cancer. Salvage radiotherapy (RT) can be a treatment option for lymph node metastasis. However, the usefulness of additional RT remains unclear after surgery or RT for the primary lung tumor.

To preserve ovarian function, we have been investigating ovarian shielding during total body irradiation (TBI) with a myeloablative dose. In this report, we update the clinical outcomes.

The inclusion criteria were clinically proven recurrent tumors, measurable by computed tomography or magnetic resonance imaging, patients ≥ 16 years old, performance status scores between 0 and 2, isolated tumor at a previously irradiated site, and a life expectancy > 6 months. The exclusion criteria were tumor invasion into the gastrointestinal tract or a major blood vessel, uncontrolled infection, early recurrence (<3 months), and severe concomitant diseases.

Methods: Patients receiving adjuvant breast RT were randomly assigned into three groups; prophylaxis, post-WBRT and control groups.
The Breast Cancer Group of the Japanese Radiation Oncology Study Group conducted a nationwide questionnaire survey on the clinical practice of postoperative radiotherapy for breast-conserving treatment for breast cancer. This questionnaire consisted of 18 questions pertaining to the annual number of treated patients, planning method, contouring structure, field design, dose-fractionated regimen, application of hypofractionated radiotherapy, boost irradiation, radiotherapy for synchronously bilateral breast cancer, and accelerated partial breast irradiation. The web-based questionnaire had responses from 293 Japanese hospitals.

The prospective open-label, randomized trial included an exploratory arm to investigate the preventive efficacy of heparinoid moisturizer for acute radiation dermatitis (ARD).
Methods: Between April 2011 and April 2013, patients receiving WBRT were assigned (1:2:2) to receive either: moisturizer for prophylaxis (group P), moisturizer starting 2 weeks after WBRT for treatment (group M), and no moisturizer (group C).
We describe the case of a 13-year-old girl with multifocal disseminated Ewing sarcoma family of tumor (ESFT) who received a 5/8 human leukocyte antigen-matched haploidentical hematopoietic cell transplantation to generate a graft-versus-tumor effect. The patient had grade 2 acute graft-versus-host disease (GVHD) of the skin and chronic GVHD nausea and abdominal pain that required prednisolone for 17 months, but has been free from ESFT for 3 years 10 months after therapy. The present case suggests a beneficial effect of haploidentical hematopoietic cell transplantation in disseminated ESFT.

Methods: A total of 30 patients were randomly assigned to receive heparinoid moisturizer (Group M), and 32 patients comprised the control group (Group C). Patients in Group M were instructed to apply heparinoid moisturizer from 2 weeks following whole-breast radiotherapy, and to continue to use the moisturizer until 3 months after completion of whole-breast radiotherapy.
Background: Treatment delays of metastatic extradural spinal cord compression (MESCC) sometimes have been reported, but reasons for its delay have remained unclear. The purpose of this study was to assess which clinical factors are associated with treatment delays in neurologically symptomatic MESCC in the hospital settings.
Methods: We reviewed medical records of MESCC patients in our institute who had at least one progressive neurological symptom (weakness, sensory changes, urinary retention, or nerve root pain), were diagnosed by magnetic resonance imaging (MRI), and were treated with at least radiotherapy.
