Postoperative proton radiotherapy for localized and locoregional breast cancer: potential for clinically relevant improvements?
When complex-target irradiation is needed, 3D-CRT often compromises the target coverage and increases the dose to OARs; IMRT can provide better results but will increase the integral dose. The benefit of IMPT is based on improved target coverage and reduction of low doses to OARs, potentially reducing the risk of late-toxicity. These results indicate a potential role of proton-radiotherapy for extended locoregional irradiation in left breast cancer.
Postmature oocytes exhibit a dynamic increase in ooplasmic microtubules. However, these changes revert after transfer of ooplasm from young oocytes.
