Summary: The study compared four techniques in prostate treatment to find the preferred technique. Plans were created for 30 prostate cancer patients using different techniques, and the quality of the plans was assessed by comparing target coverage, organs at risk, monitor units, homogeneity, and conformity among the techniques.

Summary: The management of prostate cancer recurrence after external beam radiotherapy has not been defined yet. Stereotaxic body reirradiation therapy has shown encouraging results in terms of local and biochemical control. This study compared the reirradiation outcomes and dosimetric analysis of Cyberknife treatment and VMAT-IGRT/Clarity treatment, and observed urinary and rectal toxicities, as well as biochemical control. The results indicate that VMAT-FFF allows for the delivery of a biologically equivalent dose to Cyberknife, with the advantage of reducing the likelihood of toxicities arising.

Summary: This study assessed the feasibility of using dynamic conformal arc (DCA) therapy as an alternative to volumetric-modulated arc therapy (VMAT) for the treatment of lung cancer. The results showed that WO-DCA plans can reduce treatment time and dose, protect organs, and improve treatment efficiency and quality.

Summary: This study found that VMAT plans were superior to IMRT plans in treating left-sided breast cancer patients after modified radical mastectomy. VMAT plans had better target volume coverage and conformity, and were more effective in sparing the heart. Additionally, VMAT plans reduced treatment time.

Summary: This study aimed to identify dosimetric predictive factors for facial nerve paralysis in patients with vestibular schwannomas treated with Cyberknife hypofractionated stereotactic radiotherapy. The results showed that prescriptions with a maximum dose point exceeding 30 Gy and 33 Gy substantially increased the risk of facial paralysis. Additionally, GTV minimal dose over 22 Gy, GTV mean dose over 29 Gy, PTV mean dose over 27 Gy, and PTV maximal dose of 32 Gy were identified as significant predictive factors for radiation-induced facial nerve dysfunction. Increasing the doses of hypofractionated stereotactic radiotherapy may lead to higher facial nerve toxicity and lower local control rates.

Summary: This study compares the dosimetric effects of traditional metallic ports and RFID ports in post-mastectomy VMAT planning for left-sided breast cancer. The results demonstrate that RFID ports significantly reduce distortions on CT images and result in lower doses to the heart and lungs.

Summary: This study reports the final results of a dose-escalation study of VMAT-SRS boost in patients with spine metastases. The study found that a 12 Gy dose of SRS boost after 25 Gy to the affected and adjacent vertebrae resulted in excellent local control and survival rates without significant toxicity.

Summary: Radiotherapy is crucial in breast cancer treatment, and modern techniques require higher accuracy. This study evaluated the necessity of pre-treatment and intra-fractional cone-beam computed tomography (CBCT) for verifying patient position. Most patients had minimal positional changes, but adjustments were needed for cases with extreme intra-fractional movement to ensure target coverage.

Summary: The study showed that for breast cancer patients undergoing adjuvant radiotherapy, HF-VMAT had significant advantages in reducing acute and late toxicities compared to CF-3D or HF-3D, especially in patients receiving regional node irradiation.

Summary: This study compared the treatment plans of stereotactic body radiotherapy (SBRT) with CyberKnife (CK) and high-dose-rate (HDR) intracavitary/interstitial brachytherapy (IC/ISBT) for locally advanced cervical cancer (LACC). The results showed that SBRT had better target coverage, dose sparing for organs at risk (OARs), and radiobiological effects compared to brachytherapy (BT) for tumors that are not excessively large. SBRT could be an alternative option for patients with LACC who cannot receive BT.

Summary: Properly planned single isocenter VMAT radiosurgery plans exhibit high quality and efficiency. The study compared manual planning with a new automated platform, HyperArc, and found that HyperArc produced high-quality plans with lower Paddick gradient index and mean brain doses, as well as shorter treatment times.

Summary: The study aimed to compare the rate of genitourinary toxicity in patients with prostate cancer treated with CyberKnife or volumetric-modulated arc therapy (VMAT). The results showed that CyberKnife treatment was associated with lower rates of acute prostate symptoms compared to VMAT treatment.

Summary: In this study, VMAT-based plans were found to significantly reduce the dose to organs at risk (OARs) and steepen the dose fall-off curves compared to IMRT-based plans in lung SBRT. Plans using 6-MV energy level performed better in terms of OARs dose and dose fall-off than those using 10-MV. The differences between VMAT and IMRT techniques were more obvious than those between different energy levels.

Summary: In a retrospective analysis of 76 patients with recurrent extrahepatic bile duct cancer who underwent radiation therapy, the 2-year rates of FFLP, PFS, and OS were 61%, 25%, and 33%, respectively. Univariate analysis identified disease-free interval and concurrent chemotherapy as significant prognostic factors for OS.
