Prior to Nov. 2018: PSA generally between 0.6 and 0.9 following my last HIFU in 2015
Nov. 2018: 0.9
mid-April 2019: 1.871
mid-May 2019: 2.277 - urologist says PC has returned; no biopsy; Axumin and MRI scans note "anomalous" activity in the midline suggesting recurrence, no metastases seen; begin fenbendazole (4 g) 3 days on 4 days off after reading Joe Tippens's blog
mid-July 2019: 1.824 - continue fenben 4g 3on/4 off
mid-August 2019: 1.505 - continue FZ 4g 3on/4 off
mid-September 2019: 1.996 (anxiety level rises) - continue FZ 4g now daily
mid- October 2019: 1.5 - reduce dosage to 1g or 2g (whatever I could get), sometimes daily, sometimes M-F, sometimes every other day (essentially 3on/4off) - used LabCorp because that's what LEF contracts with
mid-November 2019: 1.5 - Quest (by my PCP)
12/6/19: switched to mebendazole because fenben was getting expensive for an unproven medication and the sources on Amazon were sometimes not in stock - and it's pills instead of granules so much easier to take, and apparently just as effective - 11/21 ordered 750 mebendazole tablets 100 mg from India for $193.50 + $15 shipping - received 12/6 and started taking 2 pills with lunch (peanut butter = fat) and 2 with dinner (always some fat)
December 12, 2019: 1.4 LabCorp
Jan. 23, 2020: 1.1 Quest - this is what can happen when you don't use the same lab every time - Quest noted that their assay method could result in a reading up to 20% lower
Feb. 20, 2020: 1.4 LabCorp - makes me think Quest's reading was indeed an anomaly - sticking with LabCorp from now on
May 19, 2020: 1.3
July 20, 2020: 1.2 - reduced mebendazole dose to 2 100mg tablets daily (down from 4 daily) - so in 14 months PSA has dropped from 2.277 to 1.2
For the entire time taking fenben and mebendazole, my liver enzymes have remained consistently normal.
I began adding other purported cancer-fighting meds last year, so I have no real idea how much (if any) of the PSA drop is due to mebendazole and how much (if any) is due to the other agents (all of which I discovered on Health Unlocked prostate cancer forums):
DIM - 300 mg starting June 2019 but took it very intermittently until March 2020 - since then it's been daily
cimetidine - 200 mg since November 2019 to help low bioavailability of mebendazole and for its own possible anti-cancer properties (also helps with GERD)
loratadine - 10 mg - not sure when I added this - late last year I think (also helps with hay fever)
artemisinin - 100 mg - since August 2019 (interesting that artemisinin is an anti-helmintic like mebendazole; it stops cell division like mebendazole but in a different way
butyrate - 600 mg - since August 2019
