In the mid-1990s, Hellman et al. introduced the concept of “oligometastasis,” a state of transition between limited disease and extensive metastasis, with a limited number of metastases and organ-specific metastases, but the definition of oligometastatic prostate cancer is controversial.
The majority consensus defines oligometastatic prostate cancer as the presence of metastatic lesions on imaging in prostate patients, limited to lymph nodes or bone (not visceral metastases), and ≤ 5 metastatic lesions.
The meaning of the concept of oligometastasis is that prostate cancer is in an “intermediate state” between limited curability and widespread metastasis into a systemic disease, so some experts believe that treatment of “oligometastatic prostate cancer” can be achieved by The first of these is the use of endocrine therapy in combination with local radiotherapy to avoid the risks and complications of surgery, which can also bring benefits to patients, but radical surgery must be treated with caution.
However, some experts disagree that surgery for “oligometastatic prostate cancer” can be beneficial in the current study, and that treatment of lymph node dissection and bone metastases may be curative, and that some evidence of evidence of evidence-based medicine can be relied upon.
In conclusion, there is still a great deal of controversy as to whether oligometastatic prostate cancer warrants radical surgery, but surgery is one of the options to be considered after a rigorous screening and evaluation of patients.
