Theme: How a genetic mystery in a Māori family led to a groundbreaking medical discovery, life-altering surgeries, and new scientific understanding of diffuse gastric cancer.
Overview
This episode investigates an extraordinary story from a Māori family beset by generations of early deaths due to diffuse gastric cancer. Through their determination and collaboration with scientists, this family helped identify a genetic mutation responsible for their suffering—ultimately changing the odds for themselves and future generations. The show explores the science, emotional toll, and lifelong impacts of living without a stomach, striking a blend of curiosity, empathy, and practical insight.
Key Discussion Points & Insights
1. A Family Mystery Unfolds
- Karen Parangatai's Discovery: After her father's passing, Karen notices a troubling pattern of young deaths on his side of the family and learns it’s not an anomaly.
- Quote:
- “She noticed that a lot of people on his side had died young. Not just her cousin, but her cousin's sister, her cousin's mother, and her cousin's grandmother all gone.”
— Emily Kwong [00:17]
2. Genetic Warning and Difficult Choices
- CDH1 Mutation: Karen’s family suffers from diffuse gastric cancer caused by a mutation in the CDH1 gene—an inherited condition conferring a 70% risk.
- Testing and Dilemma: Karen tests positive for the gene and faces a wrenching decision: live with high risk or have her stomach removed.
- Quote:
- "She can get surgery to get her entire stomach removed."
— Emily Kwong [01:38]
- “Her reaction is just like, what do you mean? Can you live without a stomach? How would she eat? How would she replace it?”
— Sarah Zhang [01:48]
3. Unraveling the Science and Family Advocacy
- Tracing the Gene:
- In the 1990s, this rare cancer in Māori families led doctors to the CDH1 gene.
- Nurse Maybelle McLeod, learning of her family’s history and dismissing the myth of a “curse,” contacts scientists to solve the mystery.
- Quote:
- “The way she talked about it is that nobody talked about it. They believed it was a curse.”
— Sarah Zhang [04:49]
- Family-Led Research:
- The family took ownership—gathering over 100 samples and assembling a detailed family tree—underscoring community-driven scientific progress.
- Quote:
- “…the family goes to the scientist. Right. It isn’t the other way around.”
— Sarah Zhang [05:44]
4. Undergoing Life-Saving Surgery: What It’s Like
- Surgical Details:
- Total gastrectomy (“removal of the whole stomach”) is complex: the esophagus is reattached directly to the intestine.
- Post-surgery, eating changes dramatically—small bites, extreme chewing, and managing portions.
- Quotes:
- "You have to eat a little bit, a lot, and you have to chew a lot. Like chewing gum is how people have described it to me."
— Sarah Zhang [07:04]
- “One person literally told me she had a timer on her phone, and she would take a bite, chew, chew, chew, swallow, wait... Just so she wasn't eating too fast.”
— Sarah Zhang [07:43]
5. Adapting—Physical, Emotional, Social Impacts
- Physical Adaptation:
- The intestine forms a “pseudo-stomach.” Most people adapt, but symptoms (fatigue, nausea) can persist.
- Vitamin B12 must be supplemented; some lifelong side effects remain.
- Quote:
- “Eventually, people can eat larger portions. They don’t have to eat as many meals, and they are able to maybe put on some weight back.”
— Emily Kwong [08:49]
- Social and Psychological Effects:
- Eating out and socializing changes; some jobs become untenable during the recovery.
- Increased risk of alcohol abuse is a recurring, underappreciated consequence.
- Quote:
- “After their surgery, alcohol went down better and they found themselves drinking.”
— Emily Kwong [10:01]
- “There is some scientific evidence... that there is an association between getting bariatric surgery and later having higher risk of alcohol use disorder.”
— Sarah Zhang [10:14]
6. The Broader Medical and Ethical Landscape
- Mixed Feelings and Draconian Choices:
- Life-saving surgery is available, but doctors and patients struggle with the quality-of-life costs.
- Quote:
- “Perry Guilford...said, you know, I think in the future we’ll think these surgeries are draconian. We can’t believe... we were doing such draconian surgeries on people taking their whole stomachs out.”
— Sarah Zhang [11:52]
- Shift in Protocol:
- Now, unless you have a very clear family history, physicians may opt for monitoring over surgery.
7. Family, Connection, and Ongoing Impact
- Karen’s Outcome:
- The surgery saved Karen’s life—and unexpectedly, helped her reconnect with her father’s family and her wider heritage.
- Quote:
- “She became so much closer to her father’s family. So now she has a relationship with them. Her kids have a relationship with them. And she herself is a Māori studies professor.”
— Sarah Zhang [13:07]
- Memorable moment at a family gathering:
- “She kind of turned to her partner and said, you’re the only one out of the eight of us with a stomach.”
— Sarah Zhang [13:45]
