Synergy analysis of "classic" and newer drug combinations.
Combination chemotherapy frequently, but not always, has produced greater degrees of clinical benefit than single agent therapy. There are two potential explanations for this. Firstly, when two or more drugs are given, there is a greater probability that at least one of the drugs will be active. Second, there is the potential for true synergy, where the whole is greater than the sum of the parts.


Cell culture drug resistance testing predicts for patient survival in ovarian cancer.
There have now been 5 different studies of the relationship between the results of cell culture drug resistance testing (CCDRT)and patient survival in ovarian cancer, and all 5 studies show significant correlations between CCDRT and patient survival.

Cell culture drug resistance testing (CCDRT) improves patient survival in chemotherapy of ovarian cancer.
30 years' worth of prospective, randomized clinical trials based on attempting to identify "best" one-size-fits-all treatment regimens have produced no important progress in the chemotherapy of advanced (Stage III, IV, and recurrent/refractory) ovarian cancer.

Current Status of Drug Restance Testing Cell culture drug resistance testing (CCDRT) is purported to correlate with response to chemotherapy and/or with patient survival after chemotherapy... An extensive, diverse, and consistent literature documents the ability of cell death assays to identify forms of chemotherapy which are associated with both favorable and unfavorable prognoses.

Sub-optimal Dosing Schedules
Clinical oncologists continue to use sub-optimal dosing schedules for the most important solid tumor drug combination introduced during the past 15 years.
