More clinical information may help the forum respond.
How was it determined the PCa was in your lymph nodes, did you have surgery and they did a PLND, if so what did the pathology report say...or did you have imaging, if so, with what and what were the results? Ther e is other clinical history important in answering your question, how old, any health issues, how long did your medical team say you would be on the ADT...

In the meantime,do a literature search on doublet or triplet therapy. Here's one link, you can find others. As a side note, based on what you describe in your post, sinds like monotherapy, if so, I would consider revisiting that treatment plan with your medical team, seems like "old school."
