Like almost everyone here, I cannot comment on your lab reports - the last line is important, the details are for pathologists and consultants.
The key missing report (though a doctor would need to see many more reports), it's probably the last line that is all we need here - is the "Staging Report"
This takes the form of TNM - Tumour, Nodes, Metastases: staging is a vital part of treatment planning.
You described a tumour that appears to be T4 (probably)
We don't know if any lymph nodes are affected
We don't know if there has been distant spread - metastases.
So it is clear your father has at least 'locally advanced prostate cancer', but it is not clear whether it's Advanced Prostate Cancer or not.
In either case, there are options, but different options.
Your father needs to to discuss the pros and cons of these options with an oncologist and a surgeon. No website can substitute for that, alas, though personal experience often helps with the finer points of decision-making.
