Endometrial cancer is also called uterine cancer.<\/p>\n<p class=\"paragraph\"><b>What did this study find: <\/b>The <a href=\"https:\/\/classic.clinicaltrials.gov\/ct2\/show\/NCT03555422\" target=\"_blank\" rel=\"noopener\">phase 3 SIENDO clinical trial<\/a> found that maintenance therapy with the targeted therapy drug selinexor (Xpovio) helped delay cancer growth in people with advanced or recurrent <i>TP53<\/i> wild-type endometrial cancer. When a cancer treatment stops or shrinks the disease, <a href=\"https:\/\/www.cancer.net\/navigating-cancer-care\/how-cancer-treated\/what-maintenance-therapy\">maintenance therapy<\/a> is given after the initial treatment to help reduce the risk of the cancer coming back or delay cancer growth.<\/p>\n<p class=\"paragraph\">About half of all people with advanced or recurrent endometrial cancer have <i>TP53<\/i> wild-type tumors. &#8220;Wild-type&#8221; means that the <i>TP53<\/i> gene is found in its natural, unmutated form. People with this diagnosis typically receive initial treatment with chemotherapy, sometimes in combination with radiation therapy or surgery. As there are currently no maintenance therapies approved for people with this diagnosis, patients are usually carefully observed after initial treatment until their cancer comes back, at which point they receive the next line of treatment. For many patients, the cancer will return shortly after initial treatment.<\/p>\n<p class=\"paragraph\">Selinexor is a type of <a href=\"https:\/\/www.cancer.net\/navigating-cancer-care\/how-cancer-treated\/personalized-and-targeted-therapies\/what-targeted-therapy\">targeted therapy<\/a> called a \u201cselective inhibitor of nuclear export (SINE).\u201d SINEs block the exportin 1 (XPO1) protein, which is responsible for removing proteins from the nucleus of the cell. This can include removing a type of protein called a \u201ctumor suppressor protein\u201d that helps stop cancer cells from growing. By blocking XPO1, selinexor helps tumor suppressor proteins perform their function of slowing or stopping cancer cell growth. One type of tumor suppressor protein is p53, which is made by the <i>TP53<\/i> gene. In this study, researchers wanted to learn whether maintenance therapy with selinexor could help delay cancer growth in people with <i>TP53<\/i> wild-type tumors.<\/p>\n<p class=\"paragraph\">The SIENDO study included 113 people with advanced or recurrent <i>TP53<\/i> wild-type endometrial cancer that had shrunk following initial treatment. The study participants were randomly assigned to receive maintenance therapy with either selinexor (77 participants) or placebo (36 participants).<\/p>\n<p class=\"paragraph\">At a median follow-up of 25.3 months, the study found that maintenance therapy with selinexor significantly increased the length of time until the cancer grew. The median is the midpoint, meaning half of the participants were followed for less than 25.3 months and half were followed for longer. Overall, selinexor delayed cancer growth for a median of 27.4 months versus 5.2 months with placebo. These results supported findings from an earlier analysis of the study, which showed a delay in cancer growth and a decreased risk for death in those with <i>TP53<\/i> wild-type tumors who received selinexor.<\/p>\n<p class=\"paragraph\">The most common serious side effects in the selinexor group that did not occur in the placebo group were low white blood cell count, called <a href=\"https:\/\/www.cancer.net\/coping-with-cancer\/physical-emotional-and-social-effects-cancer\/managing-physical-side-effects\/neutropenia\">neutropenia<\/a> (18% of participants); nausea (12%); and low platelet count, called <a href=\"https:\/\/www.cancer.net\/coping-with-cancer\/physical-emotional-and-social-effects-cancer\/managing-physical-side-effects\/low-platelet-count-or-thrombocytopenia\">thrombocytopenia<\/a> (9%). About 15% of participants in the selinexor group stopped treatment due to side effects.<\/p>\n<p class=\"highlight\"><b>What does this mean for patients:<\/b>&nbsp;Selinexor may help delay cancer growth in people with advanced or recurrent <i>TP53<\/i> wild-type endometrial cancer, potentially providing these patients with an effective maintenance therapy option.<\/p>\n<p class=\"paragraph\"><a href=\"https:\/\/old-prod.asco.org\/meetings-education\/monthly-plenary-series\/program\" target=\"_blank\" rel=\"noopener\">Read this abstract and authors\u2019 disclosures on ASCO.org.<\/a><\/p>\n<p><i>\u201c<\/i><i>This is an exciting step forward in potential treatment options that will be studied further. With a weekly oral dose of selinexor, there is a possibility to remain progression-free for a much longer period than the current standard of care and substantially delay the initiation of second-line therapy.\u201d<\/i><\/p>\n<p>\u2014&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; lead study author Brian M.
