Well I got in touch with NCCN.
Thank you for your inquiry and interest in the NCCN Guidelines for Testicular Cancer.
1) The Guidelines are correct as written. CT scans apply only to patients treated with chemotherapy. For those with RPLND only - a baseline CT is recommended, as listed in Table 3 and then additional scans as indicated.
2) “As indicated” or “as clinically indicated” refers to the use of medical judgement based on probably any abdominal symptoms, H&P, and markers.
I hope this information is helpful for you.

Hope this helps anyone going through surveillance.
