Many clinical cancer therapies are less effective by using one anticancer drug only due to refractory properties of cancer pathogenesis and drug resistance property in advanced cancer patients. A general consensus among clinicians is that anticancer drug cocktail might better control cancer progresses and metastasis than single drug therapeutics in clinical trials. Despite great popularity, the anticancer drug combination dogma has not been established. The complexity of drug combination dogma discovery is more than we can expect now. This article speculates possible routes we can undertake in this matter. The background knowledge of drug combination therapy presently practiced and possible future landscapes and drawbacks of cancer drug combinative therapies are highlighted.

Bisdioxopiperazine (Biz) compounds, including ICRF-154 and razoxane (ICRF-159, Raz), are anticancer agents developed in the UK specifically targeting tumor metastases. Further three bisdioxopiperazine derivatives, bimolane (Bim), probimane (Pro) and MST- 16, have been synthesized at the Shanghai Institute of Materia Medica, Chinese Academy of Sciences, PR China after 1980. Since metastases, the prevailing deadliest pathologic feature of cancer in clinics, have been the main obstacle in cancer therapy, antimetastatic effects and mechanisms of Biz compounds are interesting and significant topics of all time for researchers undergoing the investigations of metastases biology, treatments and patho-physiology. This review addresses and highlights the different inhibitions against metastases in vivo and molecular mechanisms in vitro of Biz compounds especially relating to the inhibitions of tumor metastasis including pathways of inhibitions against angiogenesis, topoisomerase II, calmodulin, sialic acid, fibrinogen, cell-movement and so on. We argue hererin that the systematic exploration of antimetastatic activity and mechanisms of Biz compounds seems to be a shortcut for a final solution of cancer therapy in the future.
