Prostate cancer (PCa) is an increasingly prevalent health problem in the developed world. Effective treatment options exist for localized PCa, but metastatic PCa has fewer treatment options and shorter patient survival. PCa and bone health are strongly entwined, as PCa commonly metastasizes to the skeleton. Since androgen receptor signaling drives PCa growth, androgen-deprivation therapy whose sequelae reduce bone strength constitutes the foundation of advanced PCa treatment. The homeostatic process of bone remodeling - produced by concerted actions of bone-building osteoblasts, bone-resorbing osteoclasts, and regulatory osteocytes - may also be subverted by PCa to promote metastatic growth. Mechanisms driving skeletal development and homeostasis, such as regional hypoxia or matrix-embedded growth factors, may be subjugated by bone metastatic PCa. In this way, the biology that sustains bone is integrated into adaptive mechanisms for the growth and survival of PCa in bone. Skeletally metastatic PCa is difficult to investigate due to the entwined nature of bone biology and cancer biology. Herein, we survey PCa from origin, presentation, and clinical treatment to bone composition and structure and molecular mediators of PCa metastasis to bone. Our intent is to quickly yet effectively reduce barriers to team science across multiple disciplines that focuses on PCa and metastatic bone disease. We also introduce concepts of tissue engineering as a novel perspective to model, capture, and study complex cancer-microenvironment interactions.
前列腺癌(PCa)是发达国家日益普遍的健康问题。对于局限性 PCa 存在有效的治疗选择,但转移性 PCa 的治疗选择较少,患者生存时间较短。PCa 和骨骼健康密切相关,因为 PCa 通常会转移到骨骼。由于雄激素受体信号驱动 PCa 生长,降低骨骼强度的去势治疗构成了晚期 PCa 治疗的基础。骨重塑的平衡过程——由骨形成成骨细胞、骨吸收破骨细胞和调节性骨细胞的协同作用产生——也可能被 PCa 颠覆,以促进转移性生长。驱动骨骼发育和平衡的机制,如局部缺氧或基质嵌入的生长因子,可能被骨转移性 PCa 征服。通过这种方式,维持骨骼的生物学被整合到 PCa 在骨骼中生长和存活的适应性机制中。由于骨骼生物学和癌症生物学的交织性质,骨骼转移性 PCa 难以研究。在此,我们从起源、表现和临床治疗到骨骼成分和结构以及 PCa 转移到骨骼的分子介质来调查 PCa。我们的目的是迅速有效地减少跨多个学科的团队科学的障碍,这些学科专注于 PCa 和转移性骨病。我们还介绍了组织工程的概念,作为一种新的视角来模拟、捕获和研究复杂的癌症-微环境相互作用。
