Costs for orally administered cancer drugs skyrocket
New cancer drugs, taken in pill form, have become dramatically more expensive in their first year on the market compared with drugs launched 15 years ago, calling into question the sustainability of a system that sets high prices at market entry in addition to rapidly increasing those prices over time.

HPV vaccination expected to reduce cancer in all races, may not eliminate all disparities
Human papillomavirus (HPV)-associated cancers occur more frequently among Hispanics, blacks, American-Indians, and Alaska Natives than among whites. A new study from Harvard T.H. Chan School of Public Health finds that HPV vaccination is expected to reduce the cancer burden across all racial/ethnic groups. However, some disparities in cancer burden may persist and widen in the years to come if their causes, such as lack of access to diagnoses and treatment, aren't addressed.

A new discovery in the fight against cancer: Tumor cells switch to a different mode
When medication is used to shut off the oxygen supply to tumor cells, the cells adapt their metabolism in the medium term -- by switching over to producing energy without oxygen. This observation by biomedical scientists at the University of Basel and University Hospital Basel could be used for treatments that can inhibit tumor growth in the long term, as the researchers report in the latest issue of the journal Cell Reports.

Scientists predict cell changes that affect breast cancer growth
Using a broad spectrum of analytical tools, scientists from the Florida campus of the Scripps Research Institute have shown how sometimes small, often practically imperceptible, structural changes in a key breast cancer receptor are directly linked to regulating molecules and can produce predictable effects in curbing or accelerating cancer growth.

TJP1 protein may identify multiple myeloma patients most likely to benefit from proteasome inhibitors
A gene known as TJP1 (tight junction protein 1) could help determine which multiple myeloma patients would best benefit from proteasome inhibitors such as bortezomib, as well as combination approaches to enhance proteasome inhibitor sensitivity, according to a study led by the University of Texas MD Anderson Cancer Center.

Scientists uncover new way to grow rare life-saving blood stem cells
A protein called Musashi-2 regulates the function and development of important blood stem cells. This knowledge provides new strategies that can be used to control the growth of these cells -- cells that can be used as therapeutics for a range of life-threatening diseases but are, in general, in very short supply.

Breast cancer progression -- the devil is in the detail
Researchers at Helmholtz Zentrum München describe how breast cancer cells challenged with a small-molecule inhibitor targeting specific invasive properties switch to an alternative mode-of-action, rendering them even more aggressive. The results may impair future therapeutic approaches in the TGF-beta pathway and are published in the journal Oncotarget.

Study: 93 percent of advanced leukemia patients in remission after immunotherapy
Twenty-seven of 29 patients with an advanced type of leukemia that had proved resistant to multiple other forms of therapy went into remission after their T cells (disease-fighting immune cells) were genetically engineered to fight their cancers. This study is the first CAR T-cell trial to infuse patients with an even mixture of two types of T cells (helper and killer cells, which work together to kill cancer).

New model for active surveillance of prostate cancer tested
Urologists at University of California, San Diego School of Medicine and Genesis Healthcare Partners have tested a new model of care for patients with low-risk prostate cancer. The evidence-based approach uses best practices to appropriately select and follow patients to avoid disease overtreatment. Results of the three-year study are now published online in the journal of Urology.

MicroRNA pathway could lead to new avenues for leukemia treatment
Cancer researchers at the University of Cincinnati have found a particular signaling route in microRNA (miR-22) that could lead to targets for acute myeloid leukemia, the most common type of fast-growing cancer of the blood and bone marrow. These findings are being published in the April 26 issue of the online journal Nature Communications.

Breast density and outcomes of supplemental breast cancer screening
In a study appearing in the April 26 issue of JAMA, Elizabeth A. Rafferty, M.D., formerly of Massachusetts General Hospital, Boston, and colleagues evaluated the screening performance of digital mammography combined with tomosynthesis (a type of imaging) compared with digital mammography alone for women with varying levels of breast density.

Study finds readability of dense breast notifications poor
About half of American women have dense breasts, which makes it harder for mammograms to identify cancer and add to a woman's risk for cancer. Nearly half of US states have passed legislation requiring women to be notified of their breast density when they receive mammogram results, despite no scientific evidence or guidelines for appropriate care for women with dense breasts.

New hepatocellular carcinoma prognostic model improves prediction of patient survival

How breast cancer cells slide to metastasis
The spreading of cancer cells from one part of the body to another, a process known as metastasis, is the leading cause of death among cancer patients. A study published April 26 in Biophysical Journal now reveals why some cancer cells may be more metastatic than others. The findings show that breast cancer cells spread to other parts of the body by sliding around other cells blocking their escape route out of the original tumor.

Researchers look for causes of unexpected early bladder cancer recurrence after laparoscopic surgery
Although laparoscopic radical cystectomy (LRC) and robotic assisted radical cystectomy (RARC) continue to grow in popularity and are successful in the treatment of bladder cancer, they are still considered experimental approaches. Using data collected by the Section of Uro-Technology of the European Association of Urology, a team of researchers found that about 5 percent of patients experienced unexpected relapses of cancer after LRC, even with favorable pathology. Their results are reported in The Journal of Urology®.

Oscillations determine whether blood vessels grow thicker or branch
How do the cells of blood vessels decide between growing new side branches or expanding the surface? A new publication in eLife explains the mechanism and shows how the cells can behave as a collective, moving in the same direction together during blood vessel growth. The cells communicate using signals that exhibit oscillating patterns, as the scientists discovered using a combination of computer simulations and experiments. The findings are significant for diabetes and cancer.
