I describe a simple and intuitive method for finding sample size for clinical trials in primary breast cancer based on neoadjuvant trial results and using the FDA's patient-level meta-analysis. Then I explain a problem with this method and how the problem can be remedied.

background : breast cancer survival has been analyzed by many standard data mining algorithms. a group of these algorithms belonged to the decision tree category. ability of the decision tree algorithms in terms of visualizing and formulating of hidden patterns among study variables were main reasons to apply an algorithm from the decision tree category in the current study that has not studied...

The interaction of laser-generated tandem microbubble (maximum diameter of about 50  μm) with single (rat mammary carcinoma) cells is investigated in a 25-μm liquid layer. Antiphase and coupled oscillation of the tandem microbubble leads to the formation of alternating, directional microjets (with max microstreaming velocity of 10  m/s) and vortices (max vorticity of 350 000  s{-1}) in opposite...

Cancer is a fatal disease and relatively widespread in the world; Breast cancer is the most prevalent cancer among women. Hydroxyurea (HU) is a chemotherapy drug for the cure of cancer different types in patients, for example breast cancer, but has several defects, for to remove these problems in this study a nanoliposome (NL) suspension for Hydroxyurea (HU) delivery in breast cancer cell thera...
