ConclusionWe trained and cross-validated an RID predictive model with high discriminative ability at both 6 and 12 months after RT. We expect to improve the predictive power of this model by enlarging the number of training datasets.
ConclusionsPlatinum ‐based chemotherapy followed by lung‐sparing surgery (P/D) and IMRT is a feasible and safe treatment modality that yields acceptable locoregional control in patients with locally advanced MPM; however, these results should be corroborated in larger studies.

Cervical cancer is the second most common cancer in women aged 15 to 44 years worldwide [1,2]. Intensity-modulated radiation therapy (IMRT) has become the preferred radiotherapy method for locally advanced cervical cancer treatment . Accurate delineation of the clinical target volume (CTV) and organ-at-risk (OAR) is one of the essential steps for successful IMRT delivery. Such delineation is conventionally performed by radiotherapy oncologists through laborious manual delineation. The delineation is time-consuming  and heavily relies on the radiotherapy oncologists ’ experience.
Conclusions: This study demonstrated that definitive radiotherapy using 3DCRT and IMRT provides promising outcomes for locally advanced ESCC.
ConclusionThe presence of the metal port within the TTE in radiation fields resulted to insignificant increased dose differences according to the treatment technique. Future studies should assess whether this dose difference could affect clinical outcomes.
CONCLUSION: We have introduced an automated planning code with iterative optimization that produces equivalent quality plans to manual clinical planning. The resultant change in workflow results in a reduction in treatment planning times. PMID: 33016622 [PubMed - as supplied by publisher]
Abstract •PIVOTALboost evaluates benefits/toxicity of pelvic node RT and focal boost dose escalation.•Unfavourable intermediate/high risk and bulky local disease are most likely to benefit.•Functional MRI imaging is used to select patients for different types of dose escalation.•HDR brachytherapy or focal dose escalation with IMRT are used as options.•Training and support is provided to reduce variations of contouring and radiotherapy planning.•The trial is recruiting patients in 38 radiotherapy centres through the UK.

Prostate cancer is the most common malignancy in North American males and the second leading cause of cancer death. External beam radiation therapy plays an important role in the clinical management of prostate cancer of various stages. Currently, image-guided target localization for intensity-modulated radiation therapy (IMRT) of prostate cancer has become a routine procedure, and plays an essential role in dose escalation and hypo-fractionation clinical trials, especially for those that employ stereotactic body radiation therapy (SBRT) techniques.
ConclusionThis study demonstrated low toxicity of and high treatment adherence to hypofractionated adjuvant radiotherapy with SIB in a multicenter prospective trial, although the primary hypothesis was not met.
