The back pain had not gone away. On the evening of 11 September 2025, Mike had a focal seizure down his right side and lost all sensation in his leg.\u00a0Harriet\u00a0was out. His mother was at the house and called an ambulance.<\/p>\n

Even at the hospital, the family expected to be told he had a slipped or bulging disc. Staff initially indicated no scans would happen that night.<\/p>\n
A senior clinical nurse looked at Mike and changed the course of the night.<\/p>\n
\u201cIt\u2019s not your back. I need to go get my supervisor, because I don\u2019t think it\u2019s your back,\u201d\u00a0Harriet\u00a0recalled him saying.<\/p>\n
A head CT was ordered, and a full body scan followed.\u00a0Nobody used the word cancer that day,\u00a0Harriet\u00a0said. The questions the family were being asked told them enough.<\/p>\n
\u201cWhat insurances do you have?\u201d<\/p>\n
The family had private health insurance, and\u00a0Harriet\u00a0said that from the moment that was known, they felt pressure to move out of the public system. An urgent colonoscopy they were promised in hospital never happened.<\/p>\n
Harriet\u00a0used her own contacts, including two doctors she knew, to get Mike in front of a colon specialist privately. That colonoscopy, about two weeks later, confirmed the colon as the primary site.<\/p>\n

By the time the family\u2019s first appointment in the public system was due, Mike had already had three courses of cetuximab and FOLFIRI chemotherapy, and had already had a brain tumour removed privately after it doubled in size.<\/p>\n
\u201cWaiting could have been detrimental, and a very different story,\u201d\u00a0Harriet\u00a0said.\u00a0She was careful to separate the system from the people working in it. The oncologists at St George\u2019s Cancer Care work across public and private, and she said the clinicians and nurses had been extraordinary throughout.<\/p>\n
The first brain tumour was removed in November. It was five centimetres, and sat close to the area controlling movement on Mike\u2019s right side. He still has difficulty walking and has lost dexterity in his hand.<\/p>\n
Every surgery and every course of radiation forces a pause in treatment, because starting again too early risks tissue necrosis.<\/p>\n

Mike restarted treatment in January. The family had already been told there might be a second growth in his cerebellum, the part of the brain governing balance and speech, measuring a millimetre or two.<\/p>\n
In early February he could not get off the couch.\u00a0\u201cIt was like the worst case of vertigo you can ever have, where there\u2019s no reprieve,\u201d\u00a0Harriet\u00a0said.<\/p>\n
The second tumour had grown to around 27 millimetres and was pressing hard enough to need removing. After that surgery Mike had whole brain radiation, because more growths were appearing at the front of his brain.<\/p>\n
It was the way the disease was behaving, rather than any expectation, that led doctors to run further blood work. Those tests found Mike is HER2 positive.<\/p>\n
HER2 is far better understood in breast cancer than in bowel cancer, but it opened a line of treatment for Mike that conventional bowel cancer drugs could not, because HER2 targeted medicines can cross into the central nervous system where his tumours are.<\/p>\n
Roughly one to three percent of colon cancer patients develop brain metastases,\u00a0Harriet\u00a0said, and only about five percent of those are HER2 positive.<\/p>\n
Mike has since had five rounds of tucatinib and trastuzumab, at about $12,000 every three weeks, which works out at roughly $17,000 a month. Tucatinib is not yet approved by Medsafe for use in New Zealand.<\/p>\n
His next treatment is trastuzumab deruxtecan, sold as Enhertu and also known as T-DXd. It carries the same price tag.<\/p>\n
Pharmac has funded Enhertu since 1 January 2025. Its criteria restrict it to HER2 positive metastatic breast cancer, and require prior trastuzumab and chemotherapy. There is no criterion covering bowel cancer or any other solid tumour. Pharmac estimated about 120 people would receive it in the first year.<\/p>\n
Elsewhere, the same drug is approved for tumours like Mike\u2019s. The United States Food and Drug Administration granted accelerated approval in April 2024 for HER2 positive solid tumours regardless of where the cancer started, the first approval of its kind. Japan followed in March this year. Both decisions drew on a trial in HER2 positive bowel cancer patients, which found almost 47 percent responded to the drug.<\/p>\n
The family sought individual funding from Pharmac for the tucatinib and trastuzumab, under the Named Patient Pharmaceutical Assessment process.<\/p>\n
\u201cWe were told as we applied for assistance that no one really ever gets told yes,\u201d\u00a0Harriet\u00a0said.<\/p>\n
Mike has spoken to clinicians at UCLA in the United States, and the family consulted an Australian specialist about laser surgery, which is not\u00a0currently\u00a0an option because Mike has multiple lesions in his brain.<\/p>\n

\u201cEverybody\u2019s telling us this is the way forward, and everyone\u2019s excited,\u201d\u00a0Harriet\u00a0said. \u201cWe\u2019re sitting there going, yeah, it\u2019s great, it gives us options, but at what cost to us? If we don\u2019t have that money, what does that mean for Mike?\u201d<\/p>\n
Before his diagnosis Mike was a technical sales architect. He had worked at Zoom and had been in a new role at a company called Liquid Voice for six or seven weeks when he became unwell. The job involved presenting to clients and travelling around New Zealand and overseas.<\/p>\n
He has not worked since. He cannot walk easily, and typing is difficult because of the loss of dexterity in his hand.<\/p>\n
The couple\u2019s children, Patrick and Elaina, are 12 and 9.<\/p>\n
\u201cKids are really resilient, until they have a moment of un-resilience,\u201d\u00a0Harriet\u00a0said. \u201cWhen overnight your dad loses the ability to do everything that he was able to do with them before, they\u2019ve experiencing their own mourning that\u2019s happening, from the life that they had.\u201d<\/p>\n
Harriet\u00a0said no one had been able to tell the family why Mike got bowel cancer, and that microplastics had been raised once, early on.<\/p>\n
\u201cYou\u2019ve got to question why this is happening to people younger and younger.\u201d<\/p>\n
Her sister-in-law has written to Associate Health Minister David Seymour, who is responsible for Pharmac.<\/p>\n
\u201cWhat voice can we give so that people actually can get funding for unusual situations?\u201d\u00a0Harriet\u00a0said. \u201cThere\u2019ll be other people in the future that will have a similar situation. How can we be the loudest voice to help advocate for other people as well, moving forward?\u201d<\/p>\n
\u201cAre we going to find a cure? Realistically, probably no. Maybe one day there\u2019ll be one, but not for us.\u201d<\/p>\n
In June, Mike was admitted to hospital with complications from a medication, including psychosis. A doctor told the couple that Mike was his own biggest advocate.<\/p>\n
\u201cEveryone talks about it being a journey, and all of the annoying words that you use when you talk about cancer,\u201d\u00a0Harriet\u00a0said. \u201cBut I will say, it\u2019s been more of a roller coaster than a journey. And I love roller coasters. But I definitely would like to get off this one.\u201d<\/p>\n
In a statement, Pharmac chief medical officer David Hughes said the agency understood how hard it was living with a condition that required unfunded medicines, and that some families had to make difficult decisions about seeking treatment overseas.<\/p>\n

Pharmac assessed medicines for funding based on applications from pharmaceutical companies, clinicians or members of the public, and those applications focused on a specific condition because a medicine\u2019s effectiveness could differ depending on what it was used for, Hughes said.<\/p>\n
\u201cPharmac has not received an application to fund trastuzumab deruxtecan for HER2 positive bowel cancer, nor have we received an application to fund trastuzumab deruxtecan for all HER2 positive cancers, regardless of where the cancer occurs. We would welcome an application to consider these medicines for potential funding.\u201d<\/p>\n
Pharmac was considering two further applications for the drug, both for breast cancer with low HER2 expression and for advanced gastric cancer, he said.<\/p>\n
\u201cPharmac can consider applications for medicines regardless of where the cancer is located.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Mike\u00a0Hrynkewycz\u00a0thought he had pulled something painting the house.
