For what it's worth, the non-paywalled blurb seems to be saying something more specific than "fasting kills cancer", it's saying that cancers that develop resistance to cisplatin are more susceptible to fasting than cancers that aren't. So, even if cisplatin doesn't work directly, cisplatin-resistance has a beneficial side-effect that one might be able to exploit. (This point seems to have been buried under the many posts expressing an opinion or anecdote about fasting in general.)
