Compare pre-existing versus post-treatment antimitotic effects at 20 hours after the 1st dose, 20 hours after the 3rd dose, and 20 hours after the 12th dose. This is measured by tissue analysis of tumor samples with phospho-histone H3 and stains for spindle morphology to quantify mitotic index and mitotic characteristics at two time points using paired statistical analysis.

The mitotic index is a measure of cells arresting in mitosis, previously thought to be the major mechanism of taxol action. It is defined as the percentage of cells undergoing mitosis in a given population of cells. An elevated mitotic index indicates more cells are at this phase of the cell cycle at the time of sampling.

The Ki-67 protein is a cellular marker for proliferation. Ki-67 is an excellent marker to determine the growth fraction of a given cell population. The fraction of Ki-67-positive tumor cells (the Ki-67 labeling index) is often correlated with the clinical course of cancer.

SECONDARY outcome
Timeframe: Baseline and 20 hours post-first dosePopulation: Insufficient tissue was collected to complete analysis on remaining participants
There are many proposed ways to measure CIN. Here, we used # of multipolar spindles as a surrogate of CIN measures.
