Sounds good to me, like you I was diagnosed T3b NO MO, (full details on my profile) I had RT finishing December 2014 continuing on HT. Since my first appointment with the oncologist after completing RT I'm now on 6 monthly appointments which seems to be the norm. I usually go for the PSA test a few days before my appointment. Must admit it's squeaky bum time each time I have an appointment.
Take heart that they don't want to see you until June next year
