Cancer Research:Gold-diamond nano device for hyper localized cancer therapy ♦ Robotic surgery for kidney cancer ♦ New therapeutic target for breast cancer

Gold-diamond nano device for hyper localized cancer therapy Precise targeting biological molecules, such as cancer cells, for treatment is a challenge, due to their sheer size. Now, scientists have proposed an advanced solution that can potentially be applied to thermal cancer therapy. An improved sensing technique for nanometer-scale heating and temperature sensing uses a chemical method to attach gold nanorods to the surface of a diamond nanocrystal, the authors have invented a new biocompatible nanodevice.
Newly identified mechanism of p53-induced cell death could aid cancer therapy Research reveals how the tumor suppressor protein p53 works in the cytoplasm to trigger death via apoptosis and identifies a potential cancer treatment strategy.
HPV16 detection in oral rinses for oropharyngeal cancer The presence of persistent human papillomavirus type 16 DNA in oral rinses after treatment for HPV-related oropharyngeal cancer was rare but it appears to be associated with poor prognosis and therefore may have potential as a long-term tool for tumor surveillance.
First reports of robotic surgery for advanced vena cava tumor thrombus due to kidney cancer Surgery is required when cancer of the kidney causes a Level III thrombus, or clot, to develop in the major vein leading back to the heart. Traditionally this complicated procedure, inferior vena cava (IVC) thrombectomy, is performed using a large open incision, primarily because the vein is often difficult to reach. In a new article, a team of surgeons describe the first cases in which this procedure has been successfully performed robotically, using only seven small incisions and four robotic tools.
New cancer marker identified; possible therapeutic target for breast cancer Basal-like breast cancer (BLBC) is an aggressive form of breast cancer and is often referred to as "triple negative," which means it is not responsive to the common medical therapeutics. BLBC is more likely to metastasize -- or spread to different areas of the body -- quicker and earlier, and is associated with a poor prognosis. A new way to detect - and perhaps treat -- this deadly form of breast cancer has now been found.
