In a genome-wide analysis of 13 metastatic prostate cancers, scientists at the Johns Hopkins Kimmel Cancer Center found consistent epigenetic “signatures” across all metastatic tumors in each patient. The discovery of the stable, epigenetic “marks” that sit on the nuclear DNA of cancer cells and alter gene expression, defies a prevailing belief that the marks vary so much within each individual’s widespread cancers that they have little or no value as targets for therapy or as biomarkers for treatment response and predicting disease severity.
Using cervical fluid obtained during routine Pap tests, scientists at the Johns Hopkins Kimmel Cancer Center have developed a test to detect ovarian and endometrial cancers. In a pilot study, the “PapGene” test, which relies on genomic sequencing of cancer-specific mutations, accurately detected all 24 (100 percent) endometrial cancers and nine of 22 (41 percent) ovarian cancers. Results of the experiments are published in the Jan. 9 issue of the journal Science Translational Medicine.
A new drug for patients with acute myeloid leukemia (AML) marked by a specific type of genetic mutation has shown surprising promise in a Phase II clinical trial. In more than a third of participants, the leukemia was completely cleared from the bone marrow, and as a result, many of these patients were able to undergo potentially curative bone marrow transplants, according to investigators at the Johns Hopkins Kimmel Cancer Center and nine other academic medical centers around the world. Many of the participants who did well with the new drug, quizartinib or AC220, had failed to respond to prior therapies.

Since its founding, The Johns Hopkins Hospital has broken new ground, led the field in medicine and made history in countless ways. Just one of the hospital’s many historic achievements is that it was consecutively ranked #1 in the nation for 21 years out of the 23 in which U.S. News & World Report has held its annual rankings of U.S. hospitals. This year, the hospital is again ranked #1 nationally in five specialties, and it is ranked #2 overall in the nation.
Scientists at the Johns Hopkins Kimmel Cancer Center, working with Danish researchers, have developed a novel anticancer drug designed to travel -- undetected by normal cells -- through the bloodstream until activated by specific cancer proteins. The drug, made from a weedlike plant, has been shown to destroy cancers and their direct blood supplies, acting like a “molecular grenade,” and sparing healthy blood vessels and tissues.
Targeted cancer cell therapies using man-made proteins dramatically shrink many tumors in the first few months of treatment, but new research from Johns Hopkins scientists finds why the cells all too often become resistant, the treatment stops working, and the disease returns.
Two clinical trials led by Johns Hopkins Kimmel Cancer Center researchers in collaboration with other medical centers, testing experimental drugs aimed at restoring the immune system’s ability to spot and attack cancer, have shown promising early results in patients with advanced non-small cell lung cancer, melanoma, and kidney cancer. More than 500 patients were treated in the studies of two drugs that target the same immune-suppressive pathway, and the investigators say there is enough evidence to support wider testing in larger groups of patients.
Recent recommendations from the U.S. Preventive Services Task Force (USPSTF) advising elimination of routine prostate-specific antigen (PSA) screening for prostate cancer in healthy men are likely to encounter serious pushback from primary care physicians, according to results of a survey by Johns Hopkins investigators.
Johns Hopkins and Yale scientists have found that melanoma cells use a cloaking protein to hide from immune cells poised to attack the cancer.

With sharp declines in the cost of whole genome sequencing, the day of accurately deciphering disease risk based on an individual’s genome may seem at hand. But a study involving data of thousands of identical twins by Johns Hopkins investigators finds that genomic fortune-telling fails to provide informative guidance to most people about their risk for most common diseases, and warns against complacency born of negative genome test results.
Experimenting with cells in culture, researchers at the Johns Hopkins Kimmel Cancer Center have breathed possible new life into two drugs once considered too toxic for human cancer treatment. The drugs, azacitidine (AZA) and decitabine (DAC), are epigenetic-targeted drugs and work to correct cancer-causing alterations that modify DNA.
Patrick C. Walsh, M.D., a renowned Johns Hopkins urologist who pioneered work in the understanding and treatment of prostate cancer, was honored with the American Academy of Arts and Sciences’ prestigious Francis Amory Prize on March 14. Given by the Academy since 1940, the prize recognizes major advances in reproductive biology and medical care.
Johns Hopkins scientists have published laboratory data refuting studies that suggest blood vessels that form within brain cancers are largely made up of cancer cells. The theory of cancer-based blood vessels calls into question the use and value of anticancer drugs that target these blood vessels, including bevacizumab (Avastin).
Using precise information about an individual’s genetic makeup is becoming increasingly routine for developing tailored treatments for breast, lung, colon and other cancers. But techniques used to identify meaningful gene mutations depend on analyzing sequences of both normal and mutant DNA in tumor samples, a process that can yield ambiguous results. Now, a team of Johns Hopkins researchers says it has developed an easy-to-use online computer software application that can clear up any confusion faster and cheaper than other methods currently used to do the job.
After a 20-year quest to find a genetic driver for prostate cancer that strikes men at younger ages and runs in families, researchers have identified a rare, inherited mutation linked to a significantly higher risk of the disease.
Researchers at Johns Hopkins have shown that DNA changes in a gene that drives the growth of a form of lung cancer can make the cancer’s cells resistant to cancer drugs. The findings show that some classes of drugs won’t work, and certain types of so-called kinase inhibitors like erlotinib—may be the most effective at treating non-small cell lung cancers with those DNA changes.
Cancer cells have been long known to have a “sweet tooth,” using vast amounts of glucose for energy and for building blocks for cell replication.
Five Johns Hopkins students have been selected as finalists in a competition to find new ways to cure metastatic cancer.

Looking for ways to halt the uncontrolled growth of cancer cells, scientists at Johns Hopkins have found that a new class of drugs, called PARP inhibitors, may block the ability of pre-leukemic cells to repair broken bits of their own DNA, causing these cells to self-destruct. Results of their experiments, expected to be presented at the 53rd Annual Meeting of the American Society of Hematology in San Diego, Dec. 12, have already prompted clinical trials of the drugs in patients with aggressive pre-leukemic conditions, who have few treatment options.
People within the Johns Hopkins community have long known that Lillie Shockney is an amazing nurse. Now she’s got the moniker to prove it. Shockney, administrative director of the Johns Hopkins Avon Breast Center since 1997, was selected as this year’s “Amazing Nurse” in a national contest to celebrate and reward nurses’ value, sponsored by the Johnson & Johnson Campaign for Nursing’s Future. Shockney’s work with breast cancer patients was recognized by Johnson & Johnson during the 2011 CNN Heroes: An All-Star Tribute show in Los Angeles on December 11.
Working with human breast cells, researchers at the Johns Hopkins Kimmel Cancer Center have shown how the inactivation of a single copy of the breast cancer gene BRCA1 leaves breast cells vulnerable to cancer by reducing their ability to repair DNA damage, causing genetic instability. An inherited mutation in BRCA1 is the leading risk factor for hereditary breast cancer, prompting preventive mastectomies or close monitoring. The new findings may aid development of drugs to prevent hereditary breast cancer and tools to identify women who benefit most from prophylactic treatments.
Having both ovaries removed before age 45 is strongly associated with low-bone mineral density and arthritis in later years, according to a new study by Johns Hopkins oncologists and epidemiologists. The analysis covered several thousand women who took part in a U.S. government-sponsored, multiyear national health study, and excluded women whose ovaries were removed due to cancer.
Johns Hopkins Kimmel Cancer Center scientists report that sharp rises in levels of reactive oxygen molecules, and the inflammation that results, trigger biochemical changes that silence genes in a pattern often seen in cancer cells. The researchers confirmed this gene-silencing effect in mice that develop inflammation-induced colon cancer.
Scientists at Johns Hopkins have surveyed the DNA in four common types of pancreatic cysts, and have determined that each type bears a distinct pattern of gene mutations. Pancreatic cysts are present in about two percent of U.S. adults, and can, in some cases, require surgical removal and microscopic analysis to determine their type and likelihood of turning cancerous.
A new type of therapy aimed at reversing the gene-silencing that promotes cancer-cell growth has shown promising results in a small clinical trial conducted by researchers at the Johns Hopkins Kimmel Cancer Center. Forty-five late-stage lung cancer patients who received a two-drug combination designed to restore anti-cancer gene activity survived about two months longer than the expected four months, and two patients showed complete or near-complete responses despite having progressive disease after multiple standard therapies.
In dozens of experiments in mice and in human cancer cells, a team of Johns Hopkins scientists has closely tied production of a cancer-causing protein called TWIST to the development of estrogen resistance in women with breast cancer. Because estrogen fuels much breast cancer growth, such resistance — in which cancers go from estrogen positive to estrogen negative status — can sabotage anticancer drugs that work to block estrogen and prevent disease recurrence after surgery. Estrogen resistance develops in over half of women taking estrogen-blocking medications, such as tamoxifen, and exists from the start in many other women.
The spread of breast cancer is responsible for more than 90 percent of breast cancer deaths. Now, the process by which it spreads -- or metastasizes -- has been unraveled by researchers at Johns Hopkins.
Johns Hopkins Kimmel Cancer Center scientists report that sharp rises in levels of reactive oxygen molecules, and the inflammation that results, trigger biochemical changes that silence genes in a pattern often seen in cancer cells.

Doctors at Johns Hopkins have shown that during an increasingly popular type of breast-reconstruction surgery, they can safely preserve the internal mammary artery, in case it is needed for future cardiac surgery.
"Too busy," and "too complicated." These are the typical excuses one might expect when medical professionals are asked why they fail to use online error-reporting systems designed to improve patient safety and the quality of care. But Johns Hopkins investigators found instead that the most common reason among radiation oncologists was fear of getting into trouble and embarrassment.
The National Cancer Institute (NCI) has chosen Johns Hopkins as one of five centers to participate in a coordinated effort to develop a catalog of proteins created by cancer cells. The information, which will be made available to other researchers, could be used to develop new ways to detect cancer and treat the disease

But the two teams also found mutations in the NOTCH family of genes, suggesting their role as regulators of an important stage in cell development may be impaired.
Johns Hopkins scientists have developed a gene-based test to distinguish harmless from precancerous pancreatic cysts. The test may eventually help some patients avoid needless surgery to remove the harmless variety. A report on the development is published in the July 20 issue of Science Translational Medicine.
The investigators estimate that fluid-filled cysts are identified in more than a million patients each year, most of whom have undergone CT or MRI scans to evaluate non-specific symptoms, such as abdominal pain and swelling.
Identifying a suitable donor for leukemia and lymphoma patients who need bone marrow transplants may be far easier now that results of two clinical trials show transplant results with half-matched bone marrow or umbilical cord blood are comparable to fully matched tissue, thanks in large part to the availability of effective antirejection drugs and special post-transplant chemotherapy. The finding means that nearly all patients in need of a transplant can find donors, according to Johns Hopkins scientists who participated in the trials.

Hospitals and physician practices that form care-coordinating networks called "Accountable Care Organizations (ACOs)," under provisions of the new health-care law could reap cost-savings and other benefits. Experts at Johns Hopkins and the University of Pennsylvania warn, however, that such networks could potentially be designed to exclude minorities and widen disparities in health care.
Using human kidney cells and brain tissue from adult mice, Johns Hopkins scientists have uncovered the sequence of steps that makes normally stable DNA undergo the crucial chemical changes implicated in cancers, psychiatric disorders and neurodegenerative diseases. The process may also be involved in learning and memory, the researchers say.
A Johns Hopkins study of 769 men from across the United States recently diagnosed with low-grade prostate cancer shows that forgoing immediate surgery to remove the tumor or radiation poses no added risk of death. Delaying treatment is fine, the results show, so long as the cancer’s progression and tumor growth are closely monitored through “active surveillance” and there is no dramatic worsening of the disease over time.
Johns Hopkins scientists have developed a simplified, cheaper, all-purpose method they say can be used by scientists around the globe to more safely turn blood cells into heart cells. The method is virus-free and produces heart cells that beat with nearly 100 percent efficiency, they claim.
Johns Hopkins scientists and their colleagues paired laboratory and epidemiologic data to find that men using the cardiac drug, digoxin, had a 24 percent lower risk for prostate cancer.

Researchers at the Johns Hopkins University School of Medicine have discovered that nitroxoline, an antibiotic commonly used around the world to treat urinary tract infections, can slow or stop the growth of human breast and bladder cancer cells by blocking the formation of new blood vessels. The results, appearing in the Dec. 15 issue of the Journal of the National Cancer Institute, suggest that nitroxoline shows promise as a potential therapeutic agent.
Breast cancer patients are nearly 50 percent more likely to die of any cause if they also have diabetes, according to a comprehensive review of research conducted by Johns Hopkins physicians.
Lab studies show that combining drugs that target a variety of developmental cell signaling pathways may do a better job of killing deadly brain tumors than single drugs that target one pathway at a time, according to a new study by Johns Hopkins Kimmel Cancer Center researchers. The combined therapy approach apparently reduces tumor resistance to chemotherapy, they say.
Scientists at the Johns Hopkins Kimmel Cancer Center have deciphered the genetic code for medulloblastoma, the most common pediatric brain cancer and a leading killer of children with cancer.
