Arno,
I know how frustrating it can be to work with doctors who won't go along with therapies that seem pretty obvious to us. Managing our doctors (and our insurance companies!) is part of the game we all have to learn to play. I've found that respectfully showing them evidence can sometimes help. I usually send a brief email before the meeting to give them a chance to review it first. It sounds like you've already showed your doctor some things. Here are a couple more you might try...
Pre-treatment with pegfilgrastim (Neulasta), [synthetic form of granulocyte colony-stimulating factor (G-CSF)]
prevents the most dangerous kind of neutr
openia, febrile neutr
openia. So if there was evidence of neutr
openia you might want to show him the following review article that discusses the evidence for
pre-treatment. It may be that a single prophylactic dose may be enough to keep you on therapy.

Recent analyses have shown that, by reducing the risk of febrile neutropenia and chemotherapy dose delays and reductions, G-CSF prophylaxis can potentially enhance survival benefits in patients receiving chemotherapy in curative settings. Accumulating data from ‘real-world’ clinical practice settings indicate that patients often receive abbreviated courses of daily G-CSF and consequently obtain a reduced level of febrile neutropenia protection. A single dose of PEGylated G-CSF (pegfilgrastim) may provide a more effective, as well as a more convenient, alternative to daily G-CSF.
Prophylaxis of chemotherapy-induced febrile neutropenia with granulocyte colony-stimulating factorsIn fact, in the following study, they found that a prophylactic dose combined with a course of Cipro worked
better than daily doses.
The researchers said...
Pegfilgrastim (Neulasta) with/without ciprofloxacin was significantly more effective than daily G-CSF or ciprofloxacin in preventing febrile neutropenia (5% and 7% versus 18% and 22% of patients), grade 4 neutropenia, and leukopenia. Pegfilgrastim plus ciprofloxacin completely prevented first cycle febrile neutropenia and fatal neutropenic events.
Pegfilgrastim ± ciprofloxacin for primary prophylaxis with TAC (docetaxel/doxorubicin/cyclophosphamide) chemotherapy for breast cancer.Leukine (sargramostim) is a little different. It is a synthetic granulocyte
macrophage colony-stimulating factors (GM-CSF). I imagine it might be effective in preventing neutr
openia too, although the combo therapy seems to have been tried with Neulasta rather than Leukine. I looked into it as a potential way to boost the
abscopal effect of radiation treatment for my friend. His oncologist agreed to prescribe it, but insurance wouldn't pay for this "experimental" use -- it cost him about
$2000 for a 2-week cycle. GM-CSF is part of Provenge.
There is a real danger of a fatal runaway immune cascade from these medicines, so if you do take it, it is important to watch carefully for symptoms and get to the ER at the first sign. My friend described the effect as making his breathing "sticky," but he was able to tolerate it for the cycle.
Good luck managing your doctor!
