I see Tumblr is spilling in the Escapist. The research is still ongoing and only a few clinical trials with cancer patients under palliative care have been ran. From what I remember, one died and the other 4 showed reduced or halted growth. Three of the patients had not responded to various chemotherapies, two were recently diagnosed.. Their cancers weren't specified in the article, I can't find the trials on the Cancer Cel Journal or the Universities archives so I couldn't reference it. They were studied over a period of 3 months.
This is as far as human trials have gone officially, though used of DCA in combined drug therapy with traditional chemotherapy "off label" has reportedly been successful in putting cancers into remission that would have otherwise not done so with chemo alone.
However DCA has show to have paradoxical effects in some lab mice with human colorectal tumours, where apoptosis would be reduced (cell suicide) and the tumour growth would accelerate. I consider the source reliable upon referencing, though validation is again required.
They need private funding to really push this endevour forward, it's been quite stagnant for the past 4 years. As it probably mentions in the above article, the problem is pharmaceutical companies don't want to invest in anything they can't control legally.
People are right in noticing there is scientific inconsistancies in THAT article, you would be better off reading this for the facts of the initial tests:

Here are the results of the human trials (Phase II): http://dca-information.pbworks.com/f/Metabolic%20Modulation%20of%20Glioblastoma%20with%20Dichloroacetate.pdf
Mitochondria are indeed not cells as many have pointed out. They were symbiotic bacteria, but they are considered organelles. I would have also thought the RER and Golgi apparatus were where lysosomes are produced, having very little to do with the mitochondria. I only have 2 years of college Biology and years of enthusiasm in the subject with particular interests in zoology and molecular pathology, so I'm no expert.
