Esteemed New Zealand actor Sam Neill, celebrated for his roles in "Jurassic Park" and "The Piano," has passed away unexpectedly on Monday, as confirmed by his family. Despite a public battle with stage-three angioimmunoblastic T-cell lymphoma diagnosed in 2022, which led him to undergo chemotherapy and later a clinical trial involving CAR T-cell therapy, his family emphasized that he was cancer-free at the time of his death. Neill had openly shared his experience with the aggressive blood cancer in his 2023 memoir and expressed a stoic acceptance of mortality, focusing more on the experiences he would miss. CAR T-cell therapy, a treatment that genetically engineers a patient's T-cells to target and destroy cancer cells, has shown promise for certain blood cancers and was a key part of his treatment journey.

The New Zealand actor Sam Neill, known for his famous roles in 'Jurassic Park' and 'The Piano', died on Monday.

In a statement, the actor's family announced that his demise was "sudden and unexpected." Although they did not disclose the exact medical cause of death, Neill's subsequent health journey following a 2022 diagnosis of rare and aggressive stage-three blood cancer had been highly public.

Also, the family explicitly noted that he remained completely cancer-free at the time of his passing.

What happened to Sam Neill?

Neill's family was clear that his death was "sudden and unexpected". For months, he has been cancer-free.

Neill revealed first that he was being treated for stage-three angioimmunoblastic T-cell lymphoma in his 2023 memoir, Did I Ever Tell You This?

He had been undergoing chemotherapy for the cancer initially, but later he joined a clinical trial programme after chemotherapy failed. "I'm not afraid of dying," he once admitted. "What annoys me is the thought of missing out," he said.

He had said earlier that he had been living with a particular type of lymphoma for about five years. "When chemotherapy stopped working, I was at a loss, and it looked like I was on the way out," Neill said.

Neill revealed that he took part in a CAR T-cell therapy clinical trial that is focused on his type of lymphoma in Australia. "I've just had a scan just now, and there is no cancer in my body, that's an extraordinary thing," he had said in an interview.

The actor was taking a new chemotherapy drug monthly to keep the cancer at bay.

What is CAR T-cell therapy?

Known as CAR (chimeric antigen receptor) T-cell therapy, the treatment involves taking T-cells, a type of white blood cell, from a patient and genetically engineering them to target and kill cancer cells.

Though the studies are still ongoing, CAR T-cell therapy has proved particularly successful in treating certain types of blood cancers.

How modified T-cell cancer therapy works

1. Blood is drawn from the patient, and T-cells are separated out

2. The T-cells are engineered to produce surface receptors called CARs.

3. These receptors allow T-cells to attach to a specific protein on tumour cells

4. The CAR T-cells are multiplied in the lab

5. Transfused into the patient, CAR T-cells recognise and kill cancer cells
