High-Dose Vitamin C Doubles Survival for Late-Stage Pancreatic Cancer Patients
A groundbreaking clinical trial reveals that incorporating high-dose, intravenous (IV) vitamin C with standard chemotherapy significantly improves survival rates for patients suffering from late-stage metastatic pancreatic cancer. The study demonstrates that this innovative approach can extend overall survival from eight months to an impressive 16 months.
Remarkable Findings Shift Treatment Landscape
Dr. Joe Cullen, a professor of surgery and radiation oncology at the University of Iowa, led the research, which was published in the November issue of Redox Biology. "This is a deadly disease with very poor outcomes for patients," states Cullen. "When we started the trial, we thought it would be a success if we hit a 12-month survival, but we doubled overall survival to 16 months. The results were so strong that we were able to stop the trial early."
This significant finding reinforces the potential of high-dose IV vitamin C in cancer treatment, a strategy that has garnered attention over nearly two decades of research at the University of Iowa.
Study Overview: Patients and Results
The clinical trial involved 34 patients diagnosed with stage 4 metastatic pancreatic cancer. Participants were assigned to two groups: one receiving standard chemotherapy, which included gemcitabine and nab-paclitaxel, and the other receiving the same chemotherapy alongside infusions of high-dose vitamin C.
Key results from the trial included:
- Overall Survival: 16 months with chemotherapy plus vitamin C compared to eight months with chemotherapy alone.
- Progression-Free Survival: Extended from four months to six months for the group receiving vitamin C.
Cullen remarks, "Not only does it increase overall survival, but patients seem to feel better with the treatment. They experience fewer side effects and appear to tolerate more treatment, which we’ve seen in other trials as well."
Encouraging Evidence Builds for Vitamin C in Oncology
This recent study is not an isolated success. Earlier in 2023, another phase 2 trial focused on glioblastoma patients showed that high-dose IV vitamin C significantly improved survival rates when combined with standard chemotherapy and radiation. Cullen collaborated with Dr. Bryan Allen, a fellow researcher and head of radiation oncology at the university, on both trials.
A third phase 2 trial focusing on non-small cell lung cancer is currently in progress, with results anticipated within the year. All trials have been funded by a grant from the National Cancer Institute (NCI), highlighting the critical role of government support in advancing cancer treatment research.
Funding Future Research and Expanding Treatment Options
"This NCI funding was incredibly important for us to conduct these phase 2 trials and obtain these really encouraging results," notes Cullen. "Our aim is to show that adding high-dose IV vitamin C, which is inexpensive and well tolerated, can improve treatment for these deadliest cancers affecting the U.S. population."
The Long Journey of Research
Researchers at the University of Iowa have explored the potential anti-cancer effects of high-dose IV vitamin C for decades. Their pioneering work revealed a significant distinction: administering vitamin C intravenously can achieve blood concentrations unattainable by oral intake. The elevated levels of vitamin C drive unique chemical reactions within cancer cells, enhancing their susceptibility to chemotherapy and radiation treatments.
Despite initial skepticism regarding the efficacy of vitamin C as a cancer therapy, Cullen and his colleagues have continually compiled robust evidence supporting its usage. "Through every step of the process, it continued to improve," Cullen reflects. "We conducted experiments in vitro, in mice, and our phase one trials looked promising. The progression has been phenomenal."
Remarkably, one phase 1 trial combining high-dose IV vitamin C with radiation for pancreatic cancer has produced three long-term survivors, now nine years out from treatment, far exceeding typical survival expectations.
Collaborative Effort in Cancer Research
The investigatory team included influential cancer physicians and researchers from the Departments of Surgery, Radiation Oncology, and Internal Medicine at the UI Carver College of Medicine, as well as the UI College of Public Health and the Medical College of Wisconsin.
As research in this transformative area continues to evolve, the potential for high-dose IV vitamin C to redefine treatment protocols for some of the most aggressive cancers is taking shape.

What are the next steps following the findings of this clinical trial, and how might they influence future cancer treatment protocols?
Welcome to the World Today News interview! Today, we have with us Dr. Joe Cullen, professor of surgery and radiation oncology at the University of Iowa, and Dr. Bryan Allen, head of radiation oncology at the university. Both are key researchers in the groundbreaking clinical trial showing that high-dose IV vitamin C can double survival rates for patients with late-stage pancreatic cancer when combined with standard chemotherapy. Thank you both for joining us today.
Dr. Cullen, could you tell us more about the clinical trial, its aims, and how the idea of using high-dose IV vitamin C in cancer treatment came about?
Dr. Cullen: Thank you for having us. The clinical trial involved 34 stage 4 metastatic pancreatic cancer patients who were randomly assigned to two groups. One group received standard chemotherapy, which included gemcitabine and nab-paclitaxel, while the other group received the same chemotherapy alongside infusions of high-dose vitamin C. The trial’s primary objective was to assess the safety and efficacy of adding high-dose IV vitamin C to chemotherapy. We found that overall survival increased from eight months in the control group to 16 months in the group receiving both chemotherapy and vitamin C. This isn’t the first time we’ve explored the potential of vitamin C in cancer treatment; we’ve been studying it for nearly two decades at the University of Iowa. Our research revealed that administering vitamin C intravenously can create concentrations that are impossible to achieve orally, leading to unique chemical reactions within cancer cells that make them more susceptible to chemotherapy and radiation treatments.
Dr. Allen, what was your role in this study, and how did your previous work on glioblastoma patients inform this research?
Dr. Allen: My role was to oversee the radiation component of the study. We worked closely with Dr. Cullen to ensure that the combined therapies were safe and effective. Our previous phase 2 trial on glioblastoma patients, which also showed improved survival rates when high-dose IV vitamin C was added to standard treatment, provided a foundation for this research. It demonstrated the potential of using vitamin C in this
