More recently, the dogma of SF-SRS as the only means of delivering an SRS treatment has been challenged by hypofractionated SRS (HF-SRS). The ability to deliver 25-35 Gy in 3-5 HF-SRS fractions is a direct consequence of the evolution of radiation technologies to allow image guidance, specialized treatment planning, robotic delivery and/or patient positioning corrections in all 6 degrees-of-freedom, and frameless head immobilization. The intent is to mitigate the potentially devastating complication of radiation necrosis and improve rates of local control for larger metastases.

Radiotherapy alone is the most common treatment, for which several dose-fractionation regimens are available including single-fraction, short-course and longer-course regimens. Since these regimens are similarly effective regarding functional outcomes, patients with poor survival are optimally treated with short-course or even single-fraction radiotherapy. Longer-course radiotherapy results in better local control of malignant epidural spinal cord compression. Since most in-field recurrences occur 6 months or later, local control is particularly important for longer-term survivors who, therefore, should receive longer-course radiotherapy. It is important to estimate survival prior to treatment, which is facilitated by scoring tools. Radiotherapy should be supplemented by corticosteroids, if safely possible. Bisphosphonates and RANK-ligand inhibitors may improve local control. Selected patients can benefit from upfront decompressive surgery. Identification of these patients is facilitated by prognostic instruments considering degree of compression, myelopathy, radio-sensitivity, spinal stability, post-treatment ambulatory status, and patients’ performance status and survival prognoses. Many factors including patients’ preferences must be considered when designing personalized treatment regimens.</div>","PeriodicalId":49542,"journal":{"name":"Seminars in Radiation Oncology","volume":"33 2","pages":"Pages 148-158"},"PeriodicalIF":3.5,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9287573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is based on randomized controlled trials showing a survival benefit of NAC prior to RC compared to RC alone. It was anticipated that a similar survival benefit would also be seen when NAC was given prior to bladder preserving approaches, but the e phase III RTOG 8903 study which explored this concept was reported to be a negative study. However, there are a number of important caveats to be considered. First, the profile of patients opting for bladder preservation has changed from the older, frailer non-surgical candidates, to now also include younger, fitter patients opting for bladder preservation and who are also more likely to tolerate NAC. In recent years, there have also been important advances in systemic chemotherapy, immunotherapy, radiation techniques, and supportive care.

The goal of organ preservation is to treat MIBC while preserving a well-functioning natural bladder. Debate remains over the best way to optimize radiation therapy in bladder cancer. In MIBC the role of partial cystectomy has been utilized in smaller solitary tumors with adequate local control and good urinary function. As radiation therapy techniques improve and modernize, smaller radiation volumes to a partial bladder may play an increasing role as we utilize imaging techniques coupled with adaptive radiation therapy planning and other techniques such as brachytherapy.
