The Biology and Therapeutic Implications of Tumor Dormancy and Reactivation

Abstract: Advancements in the early detection of cancer coupled with improved surgery, radiotherapy, and adjuvant therapy led to substantial increase in patient survival. Nevertheless, cancer metastasis is the leading cause of death in several cancer patients. The majority of these deaths are associated with metastatic relapse kinetics after a variable period of clinical remission. Most of the cancer recurrences are thought to be associated with the reactivation of dormant disseminated tumor cells (DTCs). In this review… Show more

“…Serious attention has recently been paid to the concept of PMN which plays an important role in the outgrowth of dormant DTCs into macrometastatic tumor lesions in which EMT could be reversed into mesenchymal-epithelial transition (MET) [38,39]. PMN is established in the distant organs mainly through effects of VEGFR + bone marrow-derived cells (BMDCs) that have been driven by cytokines or exosomes secreted by the metastatic competent tumor cells in primary tissues long before extravasation of DTCs in distant tissues [40,41].…”

“…PMN is established in the distant organs mainly through effects of VEGFR + bone marrow-derived cells (BMDCs) that have been driven by cytokines or exosomes secreted by the metastatic competent tumor cells in primary tissues long before extravasation of DTCs in distant tissues [40,41]. Obviously, the reason of DTCs to be reversed from EMT to MET within PMN is that DTCs in MET state adapt better the growth conditions in distant tissues which are otherwise disfavoring the outgrowth of DTCs in EMT state [38,[42][43][44] (Figures 2 and 3).…”

“…Состояние злокачественных клеток, находящихся в метастатическом покое, регулируется метаболическими процессами в нишах внеклеточного матрикса, которые индуцируют положительные сигналы, такие как Wnt и Notch, и ослабляют отрицательные сигналы, например морфогенетического белка [6,7].…”

“…Понимание биологии «спящих» раковых клеток поможет разработке стратегий борьбы с бессимптомным остаточным злокачественным заболеванием, т. к. mts может развиваться без клинических симптомов после хирургического лечения в течение длительного послеоперационного периода. В это время циркулирующие и/или диссеминированные опухолевые клетки могут оставаться в состоянии покоя в связи с ингибированием клеточной пролиферации и активации путей выживания [6,7,10,23,34,35].…”
