\"\"For the millions of people battling cancer, the treatments options can sometimes be worse than the disease.\u00a0 Radiation and chemotherapy are the two main treatments used today and both come with vast side effects.\u00a0 While chemotherapy does attack cancer cells, and has helped some patients kick cancer out of their body, it doesn\u2019t work for everyone.\u00a0 Now a new test could tell a patient how successful chemotherapy will be.<\/p>\n

How it works<\/strong>
\nScientists at Dana-Farber Cancer Institute believe cancer cells that are on the verge of self-destruction are more likely to succumb to chemotherapy than cancer cells that have yet to reach that stage.\u00a0 While funding<\/a> for these kinds of studies is difficult, scientists believe they developed a way to test cancer cells and see how far along in the destruction process they are.<\/p>\n

“Many chemotherapy agents work by damaging structures within cancer cells,” says the study’s senior author, Anthony Letai, MD, PhD, of Dana-Farber. “When the damage becomes so extensive it can’t be repaired, the cells initiate a process known as apoptosis, in which they sacrifice themselves to avoid passing the damage on to their descendants.”<\/p>\n

\"\"How it could change treatments<\/strong>
\nIf researchers knew where in the destruction phase cancer cells were they could design more targeted drugs for cancer<\/a>, or vary the time of chemotherapy to be most effective.\u00a0 More tests need to be done, but Letai believes the results are promising.<\/p>\n

A change in medical thinking<\/strong>
\nThe findings suggest that the conventional reasoning behind the success rate of chemotherapy, the study authors say.<\/p>\n

\u201cThe traditional explanation, that chemotherapy targets fast-growing cells such as cancer cells, has some merit, but it has never been entirely satisfactory from a scientific viewpoint,\u201d Letai said.\u00a0 \u201cFor one, there are several types of fast-growing cancers that are not responsive to chemotherapy agents, and several types of slow-growing cancers that are.\u201d<\/p>\n
