Paradoxical Effects of Tumor Shrinkage on Long-Term Survival of Cancer Patients

Abstract: In this article, we challenge the existing paradigm that greater tumor shrinkage at the end of treatment leads to longer patient survival. In particular, we identify biological conditions under which the exact opposite is true. A central role in our argument about the paradoxical effect of tumor shrinkage is played by the emergence and self-selection of subpopulations of increasingly faster proliferating cancer cells. This evolutionary factor is often at work during post-treatment tumor regrowth and has a deci… Show more

“…Current cancer therapies are mainly evaluated by cytotoxicity and their effect on tumour shrinkage; however, bulk tumour regression is not the only factor in effective cancer therapies [85]. In OC, the majority of patients are diagnosed with metastatic disease which is associated with a significantly poorer prognosis, hence strategies to interrupt metastasis through the disruption of cell motility, collective movement, directed cell migration and invasion have gained interest [86].…”
