for connor, the genetic tests showed a few different mutations, the most promising of which included:
atm mutation (germline) – this mutation did not show up in the tumour tissue, it was inherited from connor’s dad, who also had cancer.
kras mutation (somatic) – this mutation is in 90+ per cent of pancreatic cancers, and by the time that connor was diagnosed, it was well studied with little progress, but there was more promising research ongoing in 2022 and our oncologist felt at that time that the researchers may be on the cusp of something and she described this as the “holy grail of pancreatic cancer,” if a targeted treatment can be discovered. note – she was right that they were onto something!
fgfr1 amplification (somatic) – this isn’t seen very often in pancreatic cancers, but it is in other cancers and there are drugs that target these types of mutations. although further down the line of priorities, it still offered an option.

what the results meant for connor…
even before we considered a clinical trial, these genetic results helped to provide some information on how connor may respond to chemotherapy, radiation as well as what existing targeted treatments could benefit him.
the atm mutation is in a similar family to the brca 1/2 mutations and increases your risk of developing certain types of cancer when inherited. it also makes you more responsive to some treatments. for example, people with an atm mutation often respond well to platinum based chemotherapy drugs, like oxaliplatin. we know now that this was the case for connor as he spent a year on folfirinox, with good disease control and a partial response. some people with the atm mutation also respond well to the parp inhibitor olaparib (lynparza). this is an oral targeted treatment with far fewer side effects than chemo and no need to go into the hospital for systemic therapy. connor spent three months on olaparib before his disease progressed. those with an atm mutation also often respond well to radiation, which connor has just started to receive for the management of bleeding and pain in august and september 2024.
