Tracking the body’s mini-shuttles
The development of a new technique for labelling the body’s own transporters — exosomes — could have long term benefits in the treatment of life-threatening medical conditions, including cancer.
Scientists create endocytosis on demand by ‘hotwiring’ cells
A solution to the problem of creating endocytosis on demand is being compared to ‘hotwiring’ a car. A team has managed to trigger clathrin-mediated endocytosis in the lab.
Medication that treats parasite infection also has anti-cancer effect
Scientists report a new gene target, KPNB1, for treatment against epithelial ovarian cancer (EOC). EOC is the fifth leading cause of cancer-related deaths in women and has a particularly grim outlook upon diagnosis. They also find that ivermectin exerts an anti-tumor effect on EOC cells by interacting with the KPNB1 gene. Because ivermectin is already approved to treat parasitic infections in patients, experiments for its effectiveness in an anti-cancer regimen is expected to significantly lower costs compared to untested drug compounds.
Ancient ink for cancer treatment
For hundreds of years, Chinese calligraphers have used a plant-based ink to create beautiful messages and art. Now, one group reports that this ink could noninvasively and effectively treat cancer cells that spread, or metastasize, to lymph nodes.
First-in-human testing of new cancer drug reported
The first clinical trials of a new drug that targets solid cancer tumors has now been tested. The Phase 1A clinical trials mark the first time ever the drug, called BXQ-350, was used in people. BXQ-350 is comprised of a human protein called SapC and a human lipid called DOPS.

- Towards personalized screening: Cumulative risk of breast cancer screening outcomes in women with and without a first-degree relative with a history of breast cancer (pages 1619–1625)Theodora Maria Ripping, Rebecca A. Hubbard, Johannes D.M. Otten, Gerard J. den Heeten, André L.M. Verbeek and Mireille J.M. Broeders
Breast cancer screening is shifting away from a one-size-fits-all approach, where age determines mammography frequency, to personalized approaches, which balance the benefits and harms of mammographic screening. This study shows that women with a first-degree family history of breast cancer are more likely to have favorable and unfavorable screening outcomes than women without a family history of the disease. Women with a family history had a higher chance of small invasive cancers being detected but also were at increased risk of interval cancers and false-positives. The findings emphasize the need for careful benefit-harm assessment in mammographic screening.
- Clinicopathological and molecular alterations in early gastric cancers with the microsatellite instability-high phenotype (pages 1689–1697)Ryo Sugimoto, Tamotsu Sugai, Wataru Habano, Masaki Endoh, Makoto Eizuka, Eiichiro Yamamoto, Noriyuki Uesugi, Kazuyuki Ishida, Tomonori Kawasaki, Takayuki Matsumoto and Hiromu Suzuki
The relevance of the clinicopathological and molecular features of early gastric cancers with the microsatellite instability (MSI)-high phenotype remains to be clarified in sporadic gastric carcinogenesis. This study shows that early gastric cancers with the MSI-high phenotype exhibit distinct histological features and accumulation of both genomic damage and MSI within the same tumors. In regions with genomic damage, the frequencies of 3p and 22q AI were significantly higher in the MSI-high phenotype than in the microsatellite stable phenotype. The treatment strategies for patients with gastric cancers having the MSI-high phenotype may thus need to differ from patients with colorectal cancer.
- High hemoglobin A1c levels within the non-diabetic range are associated with the risk of all cancers (pages 1741–1753)Atsushi Goto, Mitsuhiko Noda, Norie Sawada, Masayuki Kato, Akihisa Hidaka, Tetsuya Mizoue, Taichi Shimazu, Taiki Yamaji, Motoki Iwasaki, Shizuka Sasazuki, Manami Inoue, Takashi Kadowaki, Shoichiro Tsugane and for the JPHC Study Group
Diabetes and cancer share a positive association, yet the relationship between cancer risk and the most reliable blood glucose marker, hemoglobin A1c (HbA1c), remains unclear. This large-scale prospective study with strictly standardized HbA1c values in a Japanese population, which was cancer-free at baseline, shows that elevated HbA1c levels are significantly associated with risk for all reported cancer sites in both sexes, independent of potential confounding factors. The findings support the idea that glycemic control is key to cancer prevention in both diabetic and nondiabetic individuals with high HbA1c levels.
Rethinking Cancer, a new report by the International Longevity Centre- UK (ILC-UK) quantifies the cost of cancer to the UK economy, its families and its communities. The independent report presents research on the economic and societal impact of cancer.
The report considers the wider cost of cancer alongside the 160,000 deaths it causes each year in the UK.
- In a single year over 50,000 people of working age lose their lives to the disease and in 2014 these people could have contributed £585 million to the UK economy.
- The 1.8 million people living with and beyond cancer in the UK contribute approximately £6.9 billion to the UK economy each year through paid employment.
- The wider societal contributions of cancer survivors are significant and have been valued at £15.2 billion per year. This includes providing hours of informal care to others, along with voluntary and domestic work.
‘Rethinking Cancer’ outlines the changes required to increase survivorship and better support those living with and beyond cancer, their employers, families, friends and relatives.
Increase survival rates
The report reveals that the gap in cancer survival rates between England and the European average has remained at around 10% for the last two decades. ILC-UK calculate that closing the gap would contribute £117 million to the UK economy.
Support Cancer Survivors
Rethinking Cancer finds that if employment rates for cancer survivors were the same as for the rest of the population cancer survivors would contribute an additional £4 billion to the UK economy each year.
Even light and moderate drinking (up to one drink a day for women and up to two drinks a day for men) is associated with an increased risk of certain alcohol related cancers in women and male smokers, suggests a large study published by The BMJ today.
The study, which involved almost 136,000 people, found women who drank the equivalent of a glass of wine a day over a 30-year period were 13% more likely to develop one of the alcohol-related cancers (breast cancer being the most common) than women who didn’t drink at all.
The study found low to moderate drinking increased the risk of certain types of cancers already thought to be linked to alcohol, but only among women or people who smoked. Men who didn’t smoke and drank moderately had no increased risk of any type of cancer.

A new study published in the British Journal of Cancer indicates that cancer survival in England has steadily improved but remains lower than countries with similar healthcare systems. Is England closing the international gap in cancer survival? compared survival for colon, breast, lung, ovarian, rectal and stomach cancers in England, Australia, Canada, Denmark, Norway and Sweden between 1995 and 2009, and survival trends in England up to 2012. Of all six countries, cancer survival was lowest in England overall, while Australia and Sweden had the highest cancer survival overall.

Aim: To compare the efficacy of two interventions to promote colorectal cancer screening participation and forward stage movement of colorectal cancer screening adoption among first-degree relatives of individuals diagnosed with adenomatous polyps.
Methods: One hundred fifty-eight first-degree relatives of individuals diagnosed with adenomatous polyps were randomly assigned to receive one of two interventions to promote colorectal cancer screening. Participants received either a tailored telephone counseling plus brochures intervention or a non-tailored print brochures intervention. Data were collected at baseline and 3 months post-baseline. Group differences and the effect of the interventions on adherence and stage movement for colorectal cancer screening were examined using t-tests, chi-square tests, and logistic regression.
Results: Individuals in the tailored telephone counseling plus brochures group were significantly more likely to complete colorectal cancer screening and to move forward on stage of change for fecal occult blood test, any colorectal cancer test stage and stage of the risk-appropriate test compared with individuals in the non-tailored brochure group at 3 months post-baseline.
Conclusions: A tailored telephone counseling plus brochures intervention successfully promoted forward stage movement and colorectal cancer screening adherence among first-degree relatives of individuals diagnosed with adenomatous polyps.
