I've seen the video. Its very interesting.
I can see that she has published on and around the subject of cancer metabolism. Some of her research could probably be considerd a seminal work on the topic (obviously I've not performed a literature review on it though).
The video, and her work, do not draw any causative links between dietary sugar and the proliferation / growth / metastasis of cancer cells though.
She talks about how she wants to study this pathway as a potential therapy.
As far as I can tell, nothing has come of that, in terms of published studies.
Ted talks ≠ peer reviewed research
Neither is YouTube, but:

Because Krebs cycle.
The link between sugar and cancer is indirect - because of excess weight, from too many calories, because dietary sugar is very calorie dense.
(Obvs I'm not a dietician or a biochemist)
