Increasingly, doctors are treating lung cancer based on the genetic rearrangements driving the disease. For example, cancers that are driven by changes in the genes ALK, EGFR, and ROS1 can now all be paired with drugs that target these specific changes. However, these cancers are not only dangerous in the lung where they appear, but can become especially dangerous if they are able to metastasize to the brain – a
When prostate cancer metastasizes to bone, it can become especially dangerous – not only with its action in the bone but, interestingly, with increased aggressiveness of the overall cancer itself. Now, research presented at the American Association for Cancer Research (AACR) Annual Meeting 2018 hints at why: Cells involved in these bone metastases may release signals that drive the progression of the disease. “With prostate cancer, often a patient will
It’s no new news that viruses cause cancer. For example, human papillomavirus (HPV) causes almost all of the more than 500,000 annual worldwide cases of cervical cancer. This makes sense: By driving the proliferation of infected cells, viruses speed manufacture of more viruses, but excessive cellular proliferation is also a hallmark of cancer. Now a University of Colorado Cancer Center review published in the journal Viruses explores another strategy that
Women with obesity are more likely to get breast cancer, and a number of studies have provided a reasonable explanation why: after menopause, fat tissue manufactures estrogen, and the estrogen then promotes tumor growth. But why, then, do women with obesity continue to have more aggressive tumors even after anti-estrogen treatment? Once the tumor’s source of estrogen is removed, obesity should have no effect on prognosis, but it does. A
Not all melanomas are created equal. While most melanomas appear on the skin as the result of sun exposure, a small subset of melanomas arise spontaneously from mucosal tissues. And while targeted treatments and immunotherapies have dramatically improved the prognosis for many patients with sun-associated melanomas, these treatments are ineffective in the mucosal form of the disease. A University of Colorado Cancer Center study published today in the journal Melanoma
Phase 1 clinical trial data published this week in the journal Clinical Cancer Research show early promise of the investigational anti-cancer agent tucatinib (formerly ONT-380) against HER2+ breast cancer. The 50 women treated had progressed despite a median 5 previous treatment regimens. Twenty-seven percent of these heavily pretreated patients saw clinical benefit from the drug, with at least “stable disease” at 24 or more weeks after the start of treatment.
