I was first diagnosed in 2005 and have had a number of treatments through the years. Starting with triple hormone deprivation (Lupron-Finasteride-Casodex), prostate radiation therapy in 2008, then in 2014 chemo (taxotere), 2015 cryoablation of prostate tumor mass, 2016/2017 Zytiga followed by Xtandi, 2017 Xofigo. In Dec 2017/Jan 2018 I had a second round of radiation for a recurrent prostate lesion. Pretty much covered the waterfront of available treatments, each of which had some success at delaying, but not halting the progress of the disease. My PSA is currently quite low (0.2) after the second round of rad, but doubling every 2-3 months. Bone mets have remained dormant since chemo in 2014 and 2017 Xofigo (Radium-223) (knock wood).
While I was dealing with the various cancer treatments over the last year, something slipped up on me...cachexia (wasting). In June 2017 I weighed 170 (I'm 5'10"--my normal weight) and over the course of the next six months I slowly drifted down to around 160, which I did not consider outside my normal weight range. However, in the first six months of this year, my weight has dropped from160 to 140 (!), even though I am not anorexic and still eat a pretty varied and extensive diet. When I noticed the weight falling below 160 I actually began eating more throughout the day supplemented with fat and protein rich smoothies between meals. Under normal circumstances, I would be gaining weight at the rate I am eating. But..I'm..not.
I didn't even know what cachexia was until I developed it, but researching it online is pretty discouraging. No effective treatment, responsible for 30% of late-stage cancer patients, etc. Apparently, the body decides it is an a starvation mode and shifts the metabolism in favor of catabolic (muscle/adipose consuming) processes while suppressing anabolic (muscle building) processes, even if you are actually well nourished.
Sorry for the long back-story. I'm curious if anyone has experienced this and been successful at turning it around or at least arresting the weight loss. I'm in the ironic position that my PCa is actually pretty well controlled, but this wasting process is threatening my health and certainly my quality-of-life as it leave me fatigued and too tired to participate in the activities I am accustomed to. (It may also preclude any future aggressive treatment because I have been weakened by the wasting condition.)
Any helpful tips from the experience of others would be greatly appreciated.
