Gleevec May Help Preserve Fertility After Chemotherapy

Gleevec May Help Preserve Fertility After Chemotherapy | Melanoma Dispatch | Scoop.it

Women who undergo chemotherapy often lose their fertility because the drugs used damage or kill their oocytes—immature egg cells stored in the ovaries. However, a recent study suggests that adding the cancer drug imatinib mesylate (Gleevec) to chemotherapy treatment may protect oocytes. Researchers treated mouse ovaries with the chemotherapy drug cisplatin (Platinol) either by itself or in combination with Gleevec, then implanted them into host mice. The oocytes from Gleevec-treated ovaries still suffered DNA damage from the Platinol exposure, but unlike oocytes treated with just Platinol, they did not die. Previous research suggests that the surviving oocytes could repair the damage over time after chemotherapy treatment ends. These findings offer the hope that Gleevec may help preserve fertility in chemotherapy patients.

Clinical Trial Reveals Patients' Willingness to Undergo Genetic Testing for Personalized Cancer Treatment

Clinical Trial Reveals Patients' Willingness to Undergo Genetic Testing for Personalized Cancer Treatment | Melanoma Dispatch | Scoop.it

A recently completed clinical trial examining the use of genetic testing to direct cancer treatment was able to exceed its enrollment goal of 600 participants in less than 2 years instead of the expected 5 years. Patients were willing to participate even though they had to undergo an additional biopsy, revealing considerable interest in personalized treatment based on genetic tests. The trial confirmed that erlotinib (Tarceva) is highly effective in non-small cell lung cancer (NSCLC) patients with a mutation in the EGFR gene. It also found that NSCLC patients with mutations in the KRAS gene did not benefit from the novel cancer drug selumetinib. In contrast, not enough small cell lung cancer (SCLC) patients had any of the investigated mutations to properly test how they responded to treatments. Such mutations will require trials involving thousands of patients to draw reliable conclusions.
