Case Report: Canine High-Grade Soft Tissue Sarcoma, age 9

Partial surgical excision + fenbendazole leads to long-term survival

Fenbendazole Can Cure Cancer presents Case Reports of people (and their pets) who have treated their own cancers along with other articles to help understand how fenbendazole works. Previous articles covering other cancers are in the Archives link.

Canine soft tissue sarcoma is a general term for tumors that can occur in the soft and connective tissues of the body. Examples of soft and connective tissue include muscles, nerves, tendons, blood vessels, and fat.

Tumors that start in soft and connective tissue can be non-cancerous (benign), but those that belong to the soft tissue sarcoma group are cancerous (malignant).

Soft tissue sarcoma can occur almost anywhere because soft and connective tissues are found throughout the body. However, it most commonly occurs in the skin and layers of tissue just below the skin. They make up 8 to 15% of all tumors in dogs that occur in these areas, and most grow slowly.

The following is a Case Report from a reader who used fenbendazole to great effect to eradicate the cancer in her nine-year-old dog.

Hello! I'm delighted to see that the use of fenbendazole for cancer is gaining traction.

My story involves my big dog, Piper who is a Yellow Lab and American Staffordshire mix. She adopted us after being neglected by her previous owner, who declined to claim her.

Piper had a large external tumor that was surgically removed in January of 2019.

When I went to go pick her up following surgical excision of the tumor, the veterinarian informed me that he was not able to get all of it, because it had anchored in nerves that affect her left rear leg, saying that if he had tried to get it all, it would have done her harm to her leg and mobility.

By that time, I had learned about Joe Tippens' story about his cancer and its treatment with fenbendazole, and so I went to Tractor Supply and bought Safeguard and immediately started dosing my big girl with it. I did tell the veterinarian about my plan, and he requested that I stay in touch with him about the progress, because he had heard of it and he wanted feedback. I did as he requested, and each report has been positive. She has shown no new signs of cancer, is healthy and active and I consider her cured. That was almost 4 years ago.

I have gone on to recommend this treatment to several people, for their own personal enlightenment and potential use, not just for their pets. I personally would not hesitate to use fenbendazole myself if needed. 

Thanks for the growing exposure of this safe cancer remedy!

Q: What type of tumor was it?
A: The tumor was on her hindquarters, near the anus, about 5" long and thick like a sausage, and external, rooted in the muscles of her rump. The type of tumor was unknown to me, as the vet didn't need to have it lab analyzed.

Q: What was your fenbendazole dosing amount and schedule?
A: I gave her 400 mg of Safe-Guard fenbendazole every day mixed into her food.

Q: How long did you give her fenben?
A: I gave the fenbendazole to her for about 14 to 16 weeks. And then yes, I continued giving her 12-week treatments about three times more since then. I repeated it that same year and probably twice the following year, and that would have been in 2020.

Q: When did you notice her getting better?
A: She had not ever acted sickly, just the tumor was visible. Following surgery to remove as much of the tumor as possible, she simply never regrew that tumor or any other tumors. She healed quickly and is well. The thing that struck me strongly was that the veterinarian had assured me that the cancer would return, because he knew he could not get it all. To this day, Piper remains healthy, active, and happy, with no indication of any recurrence whatsoever.

Summary

That is a heartwarming, and apparently happily-ever-after Case Report. Piper is a lucky dog since her owner knew about fenbendazole to help her out. Even though the tumor was not biopsied or graded, a veterinarian who is a friend to this Substack, surmises that Piper’s tumor was most likely a high-grade soft tissue sarcoma primarily because of its invasion into deeper structures and nerves. Even with radiation and traditional chemotherapy, survival times are only about a year or so for high-grade metastatic tumors such as these (Hohenhaus, et al., 2016).

Even in the event of a low or intermediate-grade soft tissue sarcoma that cannot be completely removed, radiation is usually recommended to help destroy remaining cancer cells. If radiation is not done for these tumors, then expect a reoccurrence of cancer within one to three years (Hohenhaus, et al., 2016).

Piper being happy and healthy 4+ years since her partially successful surgery with no other traditional cancer treatments, is highly likely to have had the remnants and any further metastases of her tumor eradicated by fenbendazole.

Fenbendazole vs. Mebendazole vs. Albendazole vs. Flubendazole: The benzimidazoles are very similar chemically and they have very similar mechanisms of action with respect to disrupting microtubule function, specifically defined as binding to the colchicine-sensitive site of the beta subunit of helminithic (parasite) tubulin thereby disrupting binding of that beta unit with the alpha unit of tubulin which blocks intracellular transport and glucose absorption (Guerini et al., 2019). If someone asks you how fenbendazole kills the cancer cells, the answer is in italics in the previous sentence.

The class of drugs known as benzimidazoles includes fenbendazole, mebendazole, albendazole and flubendazole. Mebendazole is the form that is approved for human use while fenbendazole is approved for veterinary use. The main difference is the cost. Mebendazole is expensive ~$555 per 100 mg pill, while fenbendazole is inexpensive ~48 cents per 222 mg free powder dose (Williams, 2019). As you may recall, albendazole is the form used to treat intestinal parasites in India and these cost 2 cents per pill. FYI, to illustrate how Americans are screwed by Big Pharma, two pills of mebendazole cost just $4 in the UK, 27 cents per 100 mg pill in India and $555 per 100 mg pill in the US.

While most of the pre-clinical research uses mebendazole, probably because it is the FDA-approved-for-humans form of fenbendazole, virtually all of the self-treating clinical reports involve the use of fenbendazole. Because the preclinical cancer studies use mebendazole (ironically the human form of fenbendazole) and humans self-treat their cancers with fenbendazole (the animal form of mebendazole) it is very reasonable to assume that mebendazole and fenbendazole are functional equivalents with respect to cancer. It would be helpful if future pre-clinical and clinical investigations simply used fenbendazole as a practical matter. For the purposes of this Substack, fenbendazole, mebendazole and albendazole are used interchangably.

Where to get fenbendazole
In our experience and the experiences of those that write in, it appears that the three readily available brands of fenbendazole (Panacur-C, FenBen Labs, Happy Healing Labs) are equally effective. Panacur-C can be obtained locally in pet stores, while they all can be obtained from Amazon.

If you would like to report your experiences with fenbendazole you can do so privately by email myfenbendazole@proton.me or more publically in the Comments section in any of the articles. Also, if you know of people who’ve tried fenbendazole, and it didn’t work, we’d be especially interested in hearing from you now. Understanding the conditions and factors that enhance or impede the success of fenbendazole in treating cancer are valuable.
