Much has occurred since our 2010 report in Cancers. In the past few years we published several extensive reviews of our research so a brief review is all that will be provided here. We proposed in the earlier reports that most relapses in breast cancer occur within 5 years of surgery and seem to be associated with some unspecified manner of surgery-induced metastatic initiation. These events can be identified in relapse data and are correlated with clinical data. In the last few years an unexpected mechanism has become apparent. Retrospective analysis of relapse events by a Brussels anesthesiology group reported that a perioperative NSAID analgesic seems to reduce early relapses five-fold. We then proposed that primary surgery produces a transient period of systemic inflammation. This has now been identified by inflammatory markers in serum post mastectomy. That could explain the early relapses. It is possible that an inexpensive and non-toxic NSAID can reduce breast cancer relapses significantly. We want to take this opportunity to discuss database quality issues and our relapse hazard data in some detail. We also present a demonstration that the computer simulation can be calibrated with Adjuvant-on-line, an often used clinical tool for prognosis in breast cancer.

Cancer remains one of the leading causes of morbidity and mortality worldwide. Breast cancer is the most common form of malignancy occurring in women around the world. The aim of this present protocol is to outline the procedure for a randomised, multicentre, double blinded phase III study of perioperative Ketorolac in Women of African Descent with Operable Breast Cancer. The typical type of breast cancer in sub Saharan Africa is triple negative breast cancer (TNBC) and is usually considered the worst early breast cancer diagnosis since there are no known targeted therapies and patients often relapse and die early. sub-Saharan Africa seems the perfect place to conduct a randomized controlled double blinded clinical trial of perioperative NSAID Romano Demicheli 1, Erhabor Osaro 2, Michael Retsky 3 Forget Patrice 4.Vaidya Jayant S 5.

The primary and secondary objectives of this trial are to evaluate and compare the Disease Free Survival (DFS) and Overall Survival (OS) of operable breast cancer patients randomised to standard treatment versus standard treatment plus perioperative Ketorolac and to compare the safety and tolerability of the treatment as well as to identify pre- and post-operative factors with prognostic relevance and establish correlations with clinical outcomes. It is anticipated that trial will be successful and would turn TNBC from the worst prognosis to the best and potentially help improve the quality of life of African women suffering from breast cancer.
