Abdominal Chemo Increases Ovarian Cancer Survival Rate

Abdominal Chemo Increases Ovarian Cancer Survival Rate



A large clinical test shows that giving chemotherapy directly into the​ stomach, as​ well as​ into a​ vein, can improve survival of​ women with advanced ovarian cancer by about sixteen months. the​ results of​ the​ study, which pop up in​ this week's issue of​ the​ New England Journal of​ Medicine, prompted the​ National Cancer Institute to​ issue a​ statement supporting doctors to​ employ this plan of​ attack for​ appropriate patients.

Why is​ this new treatment reigmine so important? Ovarian cancer is​ the​ fourth greatest reason of​ cancer demises in​ women, affecting more than 22,000 women and​ killing more than 16,000 in​ 2018. Although this disease is​ super treatable when saw ahead of​ time, virtually all cases are not noticed until they have dispersed beyond the​ ovaries. Because so many ovarian cancer patients are diagnosed at​ a​ later stage, it​ is​ crucial to​ find ways to​ better treatments for​ further progressed disease.

What is​ already known about ovarian cancer? virtually all women with advanced ovarian cancer get chemotherapy after surgery to​ get rid of​ the​ tumor. That chemotherapy is​ usually given into a​ vein and​ moves through the​ bloodstream to​ reach tumor cells in​ the​ stomach. Doctors have also experimented with rendering the​ chemotherapy straight into the​ abdomen through a​ catheter, a​ system called intraperitoneal (IP) chemotherapy. Eight clinical trials of​ this approach have been done, and​ most showed a​ gain to​ IP chemotherapy. But this technique is​ not widely wore, according to​ the​ study's author, Deborah Armstrong, MD.

"There has been a​ prejudice against IP therapy in​ ovarian cancer because it's an​ old idea, it​ requires skill and​ experience for​ the​ surgery and​ for​ the​ chemotherapy, and​ it's additional complicated than IV chemotherapy," said Armstrong, who is​ a​ medical oncologist and​ associate professor at​ the​ John Hopkins Kimmel Cancer Center in​ Baltimore.

How this study was done: Women with stage III ovarian cancer were randomly assigned to​ get either standard chemotherapy in​ a​ vein (210 women), or​ a​ combination of​ chemotherapy in​ a​ vein and​ IP chemotherapy (205 women). the​ women had already had surgery that successfully removed all or​ most of​ the​ tumor; none had tumors remaining that were larger than 1 cm in​ diameter. All the​ women were treated with the​ same drugs, cisplatin and​ paclitaxel. Six cycles of​ chemotherapy were planned for​ both groups.

What was found? Women who had IP chemo operated long without their cancer coming back and​ lived longest overall. Women who had traditional chemotherapy in​ a​ vein survived about 4 years after treatment, while those who got chemotherapy in​ the​ stomach as​ well as​ a​ vein stomach an​ median of​ nearly 5 ½ years after treatment.

That improvement is​ "one of​ the​ largest benefits ever observed for​ a​ new therapy in​ gynecologic oncology," based on data from Stephen A. Cannistra, MD, who composed an​ editorial published with the​ study. He is​ a​ professor at​ Harvard Medical School and​ managing director of​ the​ division of​ gynecologic medical oncology at​ Beth Israel Deaconess Medical Center in​ Boston.

Nonetheless, the​ IP treatment was very much more difficult on the​ patients. Women who had this treatment had many additional terrible or​ life-threatening side effects, including low white blood cell counts, infection, tiredness, and​ anguish. Many side effects were associated to​ the​ catheters that must be introduced into the​ stomach to​ deliver the​ chemotherapy. These problems were so serious that fewer than half of​ the​ women designated to​ undergo IP chemotherapy finished all six designed treatment cycles. That makes the​ survival advance that good deal supplementary noteworthy, Cannistra composed.

Women who got IP therapy also reported significantly worse caliber of​ life during and​ just after treatment. By one year out, nonetheless, both groups described similar quality of​ life.
