Rounding@Iowa Podcast: “Advances in the Treatment of Pancreatic Cancer”

This episode of Rounding@Iowa is about important medical advances in the treatment of pancreatic cancer. As you listen to Dr. Clancy interview Dr. Joseph Cullen about what’s new, you’ll hear a lot about high-dose intravenous Vitamin C. This can enhance treatment and improve response to chemotherapy and radiation therapy. Dr. Cullen’s most recent study about this technique showed the overall survival of patients with late-stage pancreatic cancer increased from 8 months to 16 months.

86: Cancer Rates in Iowa Rounding@IOWA

Iowa's cancer rates are among the highest in the country, and they are rising. In this episode of Rounding@Iowa, Dr. Gerry Clancy and guest experts Dr. Mary Charlton and Dr. Mark Burkard discuss the data, risk factors, and prevention strategies clinicians can use to make a difference.

Abstract: Background

Patients with metastatic pancreatic ductal adenocarcinoma (PDAC) have poor 5-year survival. Pharmacological ascorbate (P-AscH-, high dose, intravenous, vitamin C) has shown promise as an adjunct to chemotherapy. We hypothesized adding P-AscH- to gemcitabine and nab-paclitaxel would increase survival in patients with metastatic PDAC.

Methods

Patients diagnosed with stage IV pancreatic cancer randomized 1:1 to gemcitabine and nab-paclitaxel only (SOC, control) or to SOC with concomitant P-AscH−, 75 g three times weekly (ASC, investigational). The primary outcome was overall survival with secondary objectives of determining progression-free survival and adverse event incidence. Quality of life and patient reported outcomes for common oncologic symptoms were captured as an exploratory objective. Thirty-six participants were randomized; of this 34 received their assigned study treatment. All analyses were based on data frozen on December 11, 2023.

Results

Intravenous P-AscH- increased serum ascorbate levels from micromolar to millimolar levels. P-AscH- added to the gemcitabine + nab-paclitaxel (ASC) increased overall survival to 16 months compared to 8.3 months with gemcitabine + nab-paclitaxel (SOC) (HR = 0.46; 90 % CI 0.23, 0.92; p = 0.030). Median progression free survival was 6.2 (ASC) vs. 3.9 months (SOC) (HR = 0.43; 90 % CI 0.20, 0.92; p = 0.029). Adding P-AscH- did not negatively impact quality of life or increase the frequency or severity of adverse events.

Conclusions

P-AscH− infusions of 75 g three times weekly in patients with metastatic pancreatic cancer prolongs overall and progression free survival without detriment to quality of life or added toxicity (ClinicalTrials.gov number NCT02905578).

Dr. Cullen mentions that patients contact him not infrequently to ask if taking high-dose oral Vitamin C will help them achieve similar results. Unfortunately, it will not. Giving it intravenously facilitates giving much higher doses. The study had a relatively small number of participants, which limited ascertainment of quality of life.

On the psychological side, there are ways to bolster the mental health challenges of those with pancreatic cancer, which typically has a grim outcome in terms of survival:

Spiegel D. Mind matters in cancer survival. Psychooncology. 2012 Jun;21(6):588-93. doi: 10.1002/pon.3067. Epub 2012 Mar 21. PMID: 22438289; PMCID: PMC3370072.

Further, Dr. William Breitbart, MD, Chair of the Department of Psychiatry and Behavioral Sciences at Memorial Sloan Kettering Cancer Center was interviewed in 2021 and emphasized the need for bolstering mental health for those diagnosed with pancreatic cancer. According to Breitbart, “Pancreatic cancer triggers an inflammatory response in the body, which can lead to mood disorders,” Breitbart explains. Psychiatrists can prescribe certain antidepressant medications that directly target that inflammatory response.”

Who Else Remembers the “Red Green Show”?

I was clicking through the web the other day and came across something that triggered a distant memory—The Red Green Show. It was a Canadian sketch comedy TV program that ran between 1991 and 2006.

I used to watch it and now I can’t see how I ever found the time to do that. I was in medical school between 1988-1992, and was in residency between 1992-1996. After that, I was on staff in the psychiatry department at University of Iowa Health Care.

The Red Green Show was on in the evening and it caught my attention like a couple others: Monty Python’s Flying Circus and Red Dwarf (a really quirky outer space show), which came on just before the Red Green Show. I’ve always been big on comedy, but I just don’t know how I ever found time for it. I was usually pretty tired or up all night on call.

Anyway, there’s this Red Green web site where you can watch all the episodes over the 15 years it was on—for free. The big star was Steve Smith, who played Red Green. The web site marketing all the old shows and T-shirts and whatnot is based in Overland Park in Kansas City, Kansas. Figure that one out, a Canadian TV show now selling souvenirs and Possum Lodge membership cards in Kansas City.

The show won a Canadian Gemini Award (similar to the Academy Emmy Award in America) for comedy in 1998.

If you watch one of the episodes, it’ll make you scratch your head about the notion of making Canada the 51st state, but I won’t get into it.

I had a book written by Steve Smith a long time ago but I can’t remember which one it was. I think it had a red cover. Maybe it was “How to Do Everything.” It’s a guide for do-it-yourself and self-help. That’s a hoot because I can barely tie my shoes, much less fix anything. On the other hand, neither could Red Green.

I watched the first YouTube episode from 1991 and it made me chuckle. I admit that one of the Red Green quotes, the Man’s Prayer, fits me like a fishing vest (I don’t fish!):

“I’m a man, but I can change, if I have to…I guess.” Red Green.
