Radiotherapy alone is the most common treatment for metastatic spinal cord compression (MSCC). Patients with relatively radioresistant tumors and oligometastatic disease may benefit from more intensive therapies (surgery, high-precision radiotherapy). If such therapies are not available, one can speculate whether patients benefit from dose escalation beyond the standard regimen 30 Gy in ten fractions. ⋯ Dose escalation beyond 30 Gy in ten fractions did not improve motor function, local control, and survival in MSCC patients with oligometastatic disease from relatively radioresistant tumors.

To compare acute and late toxicity after three-dimensional conformal radiotherapy to the prostate to 74 Gy (3D-CRT) with intensity-modulated radiotherapy to 78 Gy (IMRT 78) and IMRT using simultaneous integrated boost to 82 Gy (IMRT/SIB 82). ⋯ SIB enables dose escalation up to 82 Gy with a lower rate of gastrointestinal toxicity grade 3 in comparison with 3D-CRT up to 74 Gy.

Comparative Study
Radiotherapy for brain metastases from renal cell cancer: should whole-brain radiotherapy be added to stereotactic radiosurgery?: analysis of 88 patients.
To evaluate the role of stereotactic radiosurgery (SRS) and whole-brain radiotherapy (WBRT) for the treatment of brain metastases in patients with renal cell cancer (RCC). ⋯ Addition of WBRT to SRS offers better IC and should be considered for RCC patients with one to three brain metastases, especially in RPA class I group. SRS offers excellent LC rates, while WBRT should be reserved for patients with multiple metastases and poor prognosis.

The aim of the study was to record patients' symptoms of anxiety, depression and post-traumatic stress, as well as their subjective experience of illness, with different forms of radiotherapy and for different indications. The question is to be answered of whether more invasive techniques such as stereotactic radiotherapy involve greater stress or whether the psychological stress instead tends to be caused by the underlying disorder itself. ⋯ Patients who had undergone stereotactic radiotherapy did not demonstrate higher values for anxiety, depression or PTS symptoms than patients treated with conventional radiotherapy. From the results submitted here it cannot be assumed that this form of treatment leads to an increased incidence of traumatic stress or even post-traumatic stress disorder (PTSD). All in all, it is the type of underlying disorder (malignant/benign), which affects the extent of psychological stress experienced by patients following radiotherapy.
