自从Thompson最先报告过的一例以来,前列腺骨转移的偏嗜性已经认识到了。一般认为,前列腺癌以小病灶开始(A期),经一定的潜伏期后,增大成为可触及的小结节(B期),在穿过前列腺包膜以后(C期),肿瘤依次经过骨盆淋巴结(D期),上达主动脉周围淋巴结,然后到骨。大约40%的病人为D期,其中多数有骨转移。有骨转移的病人预计存活期不到5年,然而D期前列腺癌病例有20%存活5年。转移的形式前列腺癌最常转移到淋巴结,骨是其第二个常
Since one of Thompson’s first reports, the metastasis of prostatic bone metastases has been recognized. It is generally believed that prostate cancer begins with small lesions (A phase) and, after a certain incubation period, enlarges into palpable small nodules (B phase). After passing through the prostate capsule (C phase), the tumors sequentially pass through the pelvis The lymph nodes (D phase) reach the lymph nodes around the aorta and then to the bone. About 40% of patients are in stage D, and most of them have bone metastases. Patients with bone metastases are expected to survive for less than 5 years, whereas 20% of patients with stage D prostate cancer survive for 5 years. Metastatic form of prostate cancer most often metastasizes to lymph nodes, bone being its second constant
