A fundraising appeal has already raised £70,000 for a "wonderful superboy" to have treatment.
Adamas was diagnosed with neuroblastoma cancer back in July 2022 when doctors discovered the 14-month-old had a solid 13cm tumour round his left kidney.
He has been fighting for his life ever since," said his mum, Egle Jasinauskiene.
Adamas had five cycles of chemotherapy and complicated 11-hour surgery to remove his left kidney in November 2022.
"Unfortunately, post-op, routine scans showed that the tumour was growing back from the cancer cells that had been left around his main blood vessels during the surgery," Egle added.
This meant that the family started 2023 with an intensive treatment schedule, including induction chemo, stem cells transplant, 12 cycles of radiotherapy, and immunotherapy.
However, a routine scan in February 2024 showed a new three-centimetre tumour in his abdomen area.
After all the tests, the family found out that there is a cancer cell modification called NYCM which, Egle says, "can't be beaten by any more treatments that hospital has to offer".
Worse still, she says it's likely that the cancer will return if nothing is done.
There is a clinical trial called CAR-T that could help Adamas, however it takes place in Rome and is not funded by the NHS.
Egle, who decided to set up a GoFundMe page, said: "The trials cost at least £300,000, which is just a crazy amount of money for any of us.
"But it is crucial and can help to save Adamas' life. So I'm asking for help to give Adamas a chance to live.
"Thank you all so much, from the bottom of my heart."
