Article Synopsis
- Recent studies have introduced elliptical-shaped humeral head prostheses as a more anatomically accurate option for shoulder replacements, but their effects on shoulder movement compared to standard spherical heads are still unclear.
- The study involved biomechanical testing on fresh-frozen cadaver shoulders to analyze the translation of the humeral head during internal and external rotations using both elliptical and spherical implants.
- Results showed no significant differences in translation during external rotation between the two designs, but the spherical head exhibited greater compound motion and anterior translation during specific internal rotation scenarios compared to the elliptical head.
Background: The clinical value of whole brain radiotherapy (WBRT) for brain metastases (BM) is a matter of debate due to the significant side effects involved. Stereotactic radiosurgery (SRS) is an attractive alternative treatment option that may avoid these side effects and improve local tumor control. We initiated a randomized trial (NCT02353000) to investigate whether quality of life is better preserved after SRS compared with WBRT in patients with multiple brain metastases.

The purpose of this study was to compare the long-term therapeutic effect and toxicity of reRT + HT following surgery of loco-regionally recurrent breast cancer using two different reRT regimens.
Methods: The reRT regimen of the 78 patients treated in Institute A consisted of 8 × 4 Gy twice a week using mostly abutted photon-electron fields.
Background And Purpose: Patients with irresectable locoregional recurrent breast cancer en cuirasse (BCEC) do not have effective curative treatment options. Hyperthermia, the elevation of tumor temperature to 40-45 °C, is a well-established radio- and chemotherapy sensitizer. A total of 196 patients were treated with reirradiation and hyperthermia (reRT+HT) at two Dutch institutes from 1982-2005.

In this study, two nomograms were developed to overcome these limitations.
Methods: 495 patients with BMs of NSCLC treated with SRS for a limited number of BMs in four Dutch radiation oncology centers were identified and divided in a training cohort (n=214, patients treated in one hospital) and an external validation cohort n=281, patients treated in three other hospitals).
