On 8th round of Docetoxel and Cisplatin, see profile for full background details, including all the chemo symptons. Onc has agreed to extend infusion cycle to four weeks from 3 weeks in the hope I get some improved QoL. Especially since my PSA has leveled out at 0.44. Told to no longer use PSA as indicator of disease progression, though for me, it has been very consistent, but never very high, even when doubling time (PSAADT) had dropped to 3 weeks. Still only getting 3-4 good days out of 21. Have decided not to go beyond ten cycles, Research shows no survival benefit after ten cycles, probably not 8 or 9, but no one saying, plus was not studied.
