Method and device for immobilization of the human breast in a prone position for radiotherapy
ActiveUS20080230074A1Enhance the imageFacilitates therapyRestraining devicesSurgeryLocalization systemVacuum assisted
A system and method for immobilization of the human breast in a prone position during imaging and radiotherapy. The system includes a vacuum-assisted breast immobilization cup comprising two layers joined together with an air space between. The inner layer has densely perforated holes while the outer layer is airtight. When a negative vacuum is applied to the intermediate airspace the breast tissue is sucked against the mesh wall of the inner layer to preventing sliding. In addition, the cup assembly is locked into a fixed position against the patient torso via a body fixture, as well as against the patient support structure. The established geometric relationship among the cup, chest wall, imaging / treatment table or couch may be accurately repeated. The system further includes a three-dimensional localization system to uniquely place the breast in a coordinate system having fixed geometric relationship with the breast immobilization cup.

Lapatinib sustained-release implantation agent for treating solid tumors
InactiveCN101219102AOrganic active ingredientsPharmaceutical delivery mechanismEthyl phosphateToxic reaction
The invention relates to a solid tumors-curing Lapatinib sustained-release implant, which is characterized in that the sustained-release implant contains effective anti-tumor dose of Lapatinib, sustained-release auxiliary material and a certain amount of sustained-release regulator. Solid tumors consist of lung cancer, esophageal cancer, gastric cancer, liver cancer, breast cancer, ovarian cancer, prostatic cancer, bladder cancer and colorectal cancer. The sustained-release auxiliary materials are mainly one or mixture of copolymer of glycolic acid and hydroxyacetic acid, polifeprosan, poly (L-lactide-co-ethyl phosphate) and poly (L-lactide-co-propyl phosphate). When the sustained-release auxiliary materials are degrading and absorbed, Lapatinib is slowly released into tumor part, thus while reducing toxic reaction of the whole body, the sustained-release auxiliary materials can sustain concentration of effective drug at the tumor part. Placing the anti-tumor sustained-release implant at the tumor part can not only reduce toxic reaction of the whole body of Lapatinib, but also improve drug concentration at the tumor part and enhance treatment effects of nonspecific treatments, such as chemotherapeutics, radiotherapy, etc.
