He was recognised internationally with the prestigious Innes Ireland Trophy by the British Racing Drivers' Club, which is handed out to a motorsport figure for displaying qualities of courage and sportsmanship.
Randle shared the award with Dr Ian Roberts, the FIA F1 Medical Doctor who helped Romain Grosjean escape his fiery Bahrain Grand Prix crash last year.
"I didn't want to make a fuss of having to do chemo, it's something I knew I'd likely have to do since the Bathurst 1000 in October, I just wanted to put my head down and get it done," the 24-year-old said.
"It was brutal and emotional, but it's finally done, and the doctors are happy with the results, which is the main thing.
"To finish on New Year's Day was kind of fitting to put to a close a pretty challenging 2020.
"Now it gives me a clean slate to focus on getting my fitness better than where it was last year and get back to the racetrack."
He has undergone multiple surgeries, including complex abdominal surgery following the Bathurst 1000.
However, he still managed to complete a championship-winning Super2 campaign and make a second Bathurst 1000 start.
"I always knew my form of cancer wasn't a death sentence," he said.
"Testicular cancer is highly curable, and we caught it fairly early, so to be in remission now is a great feeling, and the doctors are very confident of a full recovery.
"I couldn't be more appreciative of the help I've received; my oncologist, Dr Jeremy Lewin, and my surgeon, Associate Professor Nathan Lawrentshuk, have been simply brilliant to me and to my family. I have been in very good hands.
"I also want to thank my family and all of my friends for their support during such a tough time for me."
Randle will return to the track in a S5000 on Australia Day weekend in Tasmania, less than a month after he completed his second round of chemotherapy.
He'll return to the main game at October's Repco Bathurst 1000.
