Scientists at Johns Hopkins University say they ’ve developed a gelatin - based handling that might be incredibly in effect at treating an often - fatal brain cancer . In a study of mice released this week , the gel in combination with surgery was found to eradicate 100 % of spongioblastoma tumors . It will take more research and safety testing before we can think of trying out this method acting in humans , however .
Glioblastoma is the most unwashed human body of brain cancer , accounting for around half of all basal tumors . While rarefied overall , it ’s one of the deadliest Cancer . grant to theNational Brain Tumor Society , the five - year survival rate for diagnosed spongioblastoma patient role is 6.8 % , while the median length of survival of the fittest is only eight months . More than 13,000 Americans are expected to be diagnosed with glioblastoma annually , and over 10,000 die from it every twelvemonth .
These Crab are difficult to treat for many understanding . They tend to be very aggressive and fast - growing , for one . The instinctive defense of the mentality , including the line of descent - brain roadblock , also make it hard for treatments to effectively reach the tumor site . And it ’s often impossible to whole remove tumor surgically , given the soft nature of the brain .

In the last few years , scientists have found novel drug that could possibly better treatbrain cancersthan the current banner . But researchers at Johns Hopkins and elsewhere , led by chemical substance and biomolecular railroad engineer Honggang Cui , wanted to sample a different approach . They theorized that they could bump an improved way to deliver existing drugs to the nous .
To do this , they converted the drug paclitaxel , an FDA - approved discourse for many cancers , into a result that turn itself into a hydrogel once inside the learning ability . They then mixed in an antibody that attacks a protein yell CD47 . CD47 is ordinarily found on the surface of many cells , but some cancers use CD47 to protect themselves from being eaten by resistant cells called macrophages . So the antibody is intended to turn over off this protection . Alone , neither drug taken as usual would have much gist on glioblastoma tumors . But the researchers envision that the gel could be delivered to the brain alongside surgery , with the gel satisfy up the crack of the remaining neoplasm and finishing it off for trade good .
In their new study , publishedMonday in PNAS , the team detailed the solution of their work with mouse . Amazingly , 100 % of the mouse treated with operating theatre and the gel survived . The gel also seemed to prime their immune organization and their macrophages against glioblastoma . When the research worker introduced young tumor into the surviving black eye , the mice were able to fend off the cancer on their own .
Few observational handling show this kind of success , even in former animal testing . And ease up the short track track record of current alternative for spongioblastoma , the results are certainly tantalizing . But Cui and his colleagues caution that their research is still in the very early stages of exploitation , and there are many questions leave to be answered — include whether their gel will behave the same way it does in a human brain that has glioblastoma as it seems to in a mouse brain .
“ shiner have very tiny brain , but we still have to fancy out if this can safely work with larger human wit , ” Cui told Gizmodo by telephone .
For now , human clinical enquiry is still a bit away . The squad next plans to test out their method acting in other animal model .
