Recurrent tumor after BCG: Was Docetaxel added to Gemcitabine for you?

Gem/doc treatment was pioneered at the Univ of Iowa and has been shown to give as good if not better than BCG results. Gemcitabine and Docetaxel work synergistically. i.e. they complement each other and work in different ways to attack the tumor(s). I've just had my third of 12 maintenance treatments after having had 5 weeks introductory period, after which I was declared "in remission" as there was no trace of cancer. It's a little time-consuming as each chemo which is instilled sequentially, has you lying for an hour. I have had few if any side-effects.
Some light reading for you:

Good luck.

Here is what I found on Open Evidence website and NCCN guidelines:

1. The addition of docetaxel to gemcitabine provides dual-mechanism cytotoxicity and meaningful disease control after BCG failure.
2. NCCN guidelines now list both as “other recommended” therapies for unresponsive to BCG alone. It used to be gemcitabine alone.
3. 1. The type of BCG failure may guide which to use. Late BCG relapse — most effective in using the combination of Doce/Gem. It may provide only a marginal advantage if you are an early refractory BCG failure.

Possibly this is why your doctor used gemcitabine alone or he has other rationale.

These are per guidelines and not to interfere with your doctors clinical experience. My feeling is if I have confidence in my doctor and experience, I am sure he/she has good reason to stray a bit from guidelines.

Hope this helps some.

Thanks much for this information. Will be discussing with my physician.

@gemdoc25 I am set for a third TURBT on May 8th and will then begin a course of 12 BCG treatments. I had six BCG treatments in 2024, and three Adstiladrin treatments in 2025 - 2026. I now have high grade pT1. I am highly alergic to Mitomycin (found out the hard way) and am interested in Gemcitabine (delivered as Inlexzo), or Gem-Doce, but concerned that it is a chemotherapy drug that may - or may not -share properties or actions with Mitomycin that I could not tolerate. Any information on reactions to Gemcitabine or Gem-Doc, particularly neurotoxicity?

@djr5
From what I have read there are no reports of neurotoxicity from mitomycin or Gem/Doce when instilled intravesically into the bladder. Side effects of mitomycin are dysuria, hematuria, UTI, retention, urethral stenosis. Those for Gem/doce are urgency, frequency, bladder spasms, mild flu‑like symptoms. After 8 instillations of Gem/Doce, (3 following the induction period) I have urgency and frequency which have diminished over time, but nothing else. I am not a doctor.

@gemdoc25 Thank you responding. I have the dubious distinction of being one of a very few who, immediately following intravesical instillation of mitomycin, developed acute toxic metabolic encephalopathy. Specialist Dr. Robert Penn, with the aid of an advanced lab in Utah, determined this over the course of my eight day hospital stay. The medical literature, it seems, reports that mitomycin can be associated with the development of hemolytic uremic syndrome, which in turn can be associated with irreversible renal failure, pulmonary edema, neurologic abnormalities, and has a high mortality rate. I am most grateful to Dr. Penn and my other attending physicians. Dr. Penn charted a 22 page report on the case, which he said may earn me an unwanted asterisk in the medical literature. Dr. Paras Shah, who now treats me at Mayo - Rochester, has reviewed all the copious records of the event. He assures me the drug will be kept far from me.

@djr5
I’m so very sorry you have had to suffer through that. As I said, I am not a doctor, but am surprised that mitomycin can have such negative reactions when applied intravesically only.
Good luck with alternative treatment.Best wishes.

Thank you, and best of luck with your ongoing treatment.
