Definitive radiotherapy for early stage hypopharyngeal cancer (T1–2N0M0): a retrospective study of clinical outcomes and prognostic factors
Hypopharyngeal carcinoma (HPC) is an aggressive malignancy that is often diagnosed at an advanced stage. Advances in narrowband imaging have increased the early detection rate of HPC. Definitive radiotherapy (RT) is a noninvasive, organ-...

Risk stratification for distant metastasis after postoperative (chemo)radiotherapy in head and neck squamous cell carcinoma
With the emergence of immune checkpoint inhibitors for resectable locally advanced head and neck squamous cell carcinoma (HNSCC), identifying patients most likely to experience distant relapse after standard postoperative treatment has b...

Time-resolved lipidomic atlas of the murine lung response to acute ionizing radiation
The lung is among the most radiosensitive organs and a principal dose-limiting organ in thoracic radiotherapy, yet the acute metabolic consequences of irradiation at the lipidomic level remain poorly characterized. We constructed a time-...

Antitumor effects of combined local plasma and anti-PD-1 antibody treatment in a murine colon tumor model
Cold atmospheric-pressure plasma has been suggested to induce antitumor immune responses as a local anticancer treatment. In this study, we investigated whether streamer discharge plasma, a type of cold atmospheric-pressure plasma, enhan...

Long-term outcomes of high-dose hyperfractionated thoracic radiotherapy for limited-stage small-cell lung cancer
Concurrent chemoradiotherapy with thoracic radiotherapy of 45 Gy in 30 twice-daily fractions is the standard treatment for limited-stage small-cell lung cancer (LS-SCLC). However, the optimal thoracic radiotherapy dose remains uncertain....

Revision of lymph node classification in the Japanese Classification of Esophageal Cancer and its impact on definitive chemoradiotherapy for stage IV esophageal cancer: a single-institution retrospective study
The 2022 revision of the Japanese Classification of Esophageal Cancer reclassified certain lymph node metastases previously considered locoregional as distant lymph node metastasis. Consequently, some patients previously diagnosed with s...

Current practices and challenges in inverse planning for gynecologic brachytherapy: insights from a multi-institutional study
This study investigated the feasibility and reproducibility of inverse planning (IP) in gynecologic high-dose-rate brachytherapy (BT) across ten institutions (five IP and five manual). Two pre-defined cases (high-risk clinical target vol...

Endoscopic ultrasound–guided fiducial marker placement for image-guided proton beam therapy in pancreatic cancer: implications for positional accuracy and position management
High geometric precision is essential in proton beam therapy (PBT) for pancreatic cancer. This study evaluated inter-fraction positional accuracy during image-guided PBT using radiopaque surrogates and assessed endoscopic ultrasound–guid...

Efficacy and safety of risk-adapted modified stereotactic body radiotherapy for lung tumors: a single-institution retrospective study
This study evaluated the clinical outcomes and safety of risk-adapted stereotactic body radiotherapy (SBRT) using non-standard fractionation schedules for lung tumors adjacent to organs at risk (OARs). We retrospectively analyzed 81 cons...
