Pancreatic Cancer Recurrence after Whipple

My story is a little different but worth telling here. I had a Whipple procedure in 2012 and was staged as III, locally advanced, borderline resectable. Surgical margins were clear. There was portal vein resection required and pathology showed invasion into the vascular wall. Eleven of 22 lymph nodes were positive. One week after surgery a CT was done and the radiologist noted suspicion of metastatic disease to the liver. It was not large enough to be seen two weeks earlier at the time of the initial CT scan. So this was how I ended up having a Whipple and being stage IV…..it had not been detected prior to surgery that was done a couple of days after the initial diagnosis. No cure was to be achieved for me by having the Whipple.

My first thoughts on treatment were to find a clinical trial. To make the search easier, molecular profiling was done and a liquid biopsy revealed a germline (inherited) mutation. So now I knew the type of trials to focus my search on. A trial matching my criteria would take 14 months so in the meantime, standard of care chemo was required. Standard of care is just what it means….and it was not going to give me the longevity in survival I was looking for. I knew I would require better than SoC and strongly advocated for more aggressive chemo.

The “gold standard” of chemotherapy regimens in 2012 as it is today is Folfirinox. Administering 12 cycles is the number selected that is felt to achieve No Evidence of Disease (NED) and yet be tolerable by the majority of patients as adverse events, side effects and peripheral neuropathy are concerns. Few oncologists explain what NED means, especially in how it is determined. The goal of the oncologist is to knock the disease down low enough that it is not detectable by current sensitivity by imaging such as CT, MRI or PET. It is hoped that at this level, one’s immune system can keep any minimal residual disease (MRD) in check. As long as one continues to have a robust immune status, the MRD is held in check. But is the immune system comes under challenge and gets compromised, MRD can come back and usually in a more aggressive form.

Knowing this is why I advocated for more aggressive treatment with Folfirinox. Rather than stopping at 12 cycles, I indicated my desire and committed to doing as much as my body would tolerate. Thankfully my oncologist honored my request. Because neuropathy would likely be experienced and could become permanent, he decided to treat with six cycles of Folfirinox (FFX) followed by six resting cycles of just 5-FU with Leucovorin. After those six cycles, it was back to full-dose FFX for another six cycles. This alternating dosing regimen went for 24 months resulting in a total of 46 cycles of 24 FFX and 22 of 5-FU. At that point, a clinical trial opened that I met the criteria for and enrolled after a two week washout period. After the final 5-FU treatment, all liver metastasis had shrunk 80% and it was believed only scar tissue was being observed on imaging.

The clinical trial was designed to target a gene mutation for maintenance monotherapy. Many oncologists feel it was the excessive FFX that destroyed any MRD and the clinical trial drug has helped in preventing any new primary tumor from forming in the residual pancreas as I have a lifetime risk from that gene mutation.

Anyone can say to their oncologist they want to survive and be cured. Saying and doing are two very different things. I was 55 years old and strong physically from having done 100-200 mile bike rides per week. I was also strong emotionally and mentally. I set realistic expectations that setbacks might be encountered. I found ways to tolerate the treatment, deal with a setback and then move forward. I stayed focused on my goal and had the determination and very strong will to survive. In 2016 at the conclusion of the trial I was declared NED. It was likely I was already NED at the conclusion of the FFX treatments. In 2022 I was informed by a number of pancreatic cancer oncologists that they consider me cured. In a few months I will be celebrating 11 years of survival of having had stage IV disease.

Stage1vsurvivor, incredibly inspiring story. I have a similar story. Three months after having a successful Whipple procedure, cancer was discovered in my liver. I've just completed my 8th treatment of FFX and tumors are shrinking. You have inspired me to stay the course and keep fighting and talk to my oncologist about a similar path. Thank you and wish you all the best.

Congrats to you that your chemo is working. I had surgery in late 2022 and was “cancer free” for 4 mo the before it metastasized it liver and abdominal area. I’ve been on GAC chemo for 8 months but now the chemo is no longer working. May I ask what your mutation cocktail is? Mine is ATM, KRAS12D, and TP53 and maybe more I’m not even aware of by now.

I'm sorry but I don't have the answer to your question. I am in the process of have blood maker testing done through Guardant. it's called the 360 test. This test will capture the DNA shed from tumors in the blood. It will provide a comprehensive overview of the genomics in both the primary tumor and metastatic sites. The test is used to detect gene mutations in circulating cell free DNA {cfDNA}. The hope is they will be able to identify the best form of treatments going forward. Hope this information may help. I certainly wish you all the best in your fight.

My husband had a total pancreatectomy, with duodenum, spleen, pylorus, gall bladder and supporting tissues removed plus a cadaver replacement of the portal vein due to tumor found during the surgery. All perimeters were clean, but still 6 mon later sneaky metastasis had gone to the adrenals, chemo tried but then a precision therapy with immunotherapy based on his tumor dna and mutations brought clearing of all visible cancer for the ensueing years 3 years, now off of immunotherapy due to side effects for 1.5 years. The additional years have been so good now at 5.5 years post diagnosis. The advances in the personalized medicine, Keytruda, approaches with the individual studies of the tumor made a difference, precision medicine. Hoping that you will find this can happen for you as you go through the tests.

Great news! We are told that immunotherapy is having very limited results with pancreatic cancer. Would you share which mutations your husband has?

Keytruda is working for so many things now. Wish I had invented it! Almost a wonder drug!

My mom was 2b at diagnosis. Had chemo and radiation which did very little, but they went ahead with Whipple. She had been in remission for almost 3 years until a CT scan followed by PET confirmed the worst. Mets to ovary and bladder. She is now back in treatment. Chemo and radiation. Both her oncologist and radiologist have given her reason to believe they might be able to beat this down again and get her back to remission. Of course, we don't know for sure if this will work, but we're hoping! New therapies and discoveries are happening every day, so keep pushing through!
