Monitoring, not treatment may be better for certain prostate cancer cases

A new study conducted on 33,000 Swedish men with very low risk (stage I) prostate cancer indicates that close monitoring maybe a more viable option than immediate treatment.  According to lead researcher Dr. Stacy Loeb, assistant professor in the departments of urology and population health at NYU Langone Perlmutter Cancer Center in New York, "there is no rush to get treatment...low-risk prostate cancer can be safely monitored...some men will eventually need treatment, but others will be able to preserve their quality of life for many years."

Preventive mastectomy rates have doubled over the past decade; fear is a factor

A new study, recently presented at the American College of Surgeons meeting in Washington D.C., indicates that rates of contralateral prophylactic mastectomy (CPM) have doubled in the United States over the past 10 years.  According to the study authors, nearly "25% of newly diagnosed breast cancer patients undergo this procedure"; fear of cancer recurrence is believed to be the primary reason.

Further evidence linking obesity to liver cancer

A recent study conducted by the American Cancer Society provides further evidence on the link between high body mass index (BMI) and risk of liver cancer.  According to study co-author Peter Campbell, an examination of 1.57 million adults across 14 U.S. studies found that 6.5% of participants were diagnosed with type 2 diabetes.  Of these,over 2.000 developed liver cancer.

Smokeless tobacco associated with higher risk of prostate cancer death

A new study conducted at the Harvard T.H. Chain School of Public Health in Boston indicates that snus, a smokeless tobacco product, may increase risk of death in a patient with prostate cancer.  According to study co-author Kathryn Wilson, the study, conducted on thousands of Swedish men from 1971-1992, determined that "those who used snus but did not smoke has a 24% higher risk of death from prostate cancer during the study period."

Cryoblation as possible alternative for treating early stage breast cancer

A new study conducted at the University of California Los Angeles David Geffen School of Medicine purports that the cryoblation freezing technique may be a possible treatment mechanism, in lieu of lumpectomy, for small early-stage breast cancers.  According to Dr. Deanna Attai, assistant clinical professor of surgery, the study,conducted on 86 patients, found that overall, "freezing was successful for 92% of the worked for all tumors measuring less than 1 centimeter."

Diagnosis of cancer as a medical emergency leads to poorer prognosis for many patients

Too many patients - particularly those from disadvantaged backgrounds - are being diagnosed with cancer as medical emergencies, say researchers. This means that their chances of successful treatment are greatly reduced.

In an article in the journal Nature Reviews Clinical Oncology, a team of researchers jointly led by the University of Cambridge and University College London reviewed current evidence from 26 peer-reviewed studies and 6 online reports from 7 countries. The evidence indicates that emergency diagnosis of cancer is a universal problem, challenging previous assumptions regarding this issue being a particular problem only in the UK.

Night shift work and breast cancer risk

Data from three new UK studies and from a review of currently available evidence, published in the Journal of the National Cancer Institute, indicates that night shift work has little or no effect on breast cancer incidence.

Compared with women who had not reported doing night shift work, the combined relative risks taking all 10 studies together were 0.99 for any night shift work, 1.01 for 20 or more years of night shift work, and 1.00 for 30 or more years night shift work. In other words, the incidence of breast cancer was essentially the same whether someone did no night shift work at all or did night shift work for several decades.

Five challenges of delivering immuno-oncology trials and how to overcome them

Recent advances have seen immuno-therapy become a shining light within oncology research, transforming both the way cancer treatments are viewed and the potential standards of care and outcomes.

These are exciting developments, but at the same time can add huge complexities to the drug development process, particularly around the trial stages and processes. Particular areas of focus include more sophisticated site selection and advanced monitoring/oversight processes to moderate cost and risk, especially in early phases.

Quintiles‘ Eric Groves, MD, PhD, Vice President, Scientific Advisor, Advisory Services proposes there are five key challenges which when addressed, mitigate the majority of risks that can accompany immuno-oncology trials and has produced a blog which looks at each of them.

Hormone therapy for prostate cancer less safe for men with prior heart attack

A new study conducted at Yale University's Department of Therapeutic Radiology indicates that hormone-depleting therapy, often prescribed to men with prostate cancer, may pose a risk for those patients who have survived a heart attack.  While the study noted that younger patients with less cardiac risk factors benefited more positively from the hormone therapy, Dr. Manish Vira, vice chair for urologic research at the Arthur Smith Institute for Urology in New Hype Park,New York, stated tat "men who had prior documented history of heart disease as demonstrated by prior heart attack were potentially harmed by the addition of hormonal therapy."

Many cancer caregivers report feeling unprepared for caregiving challenges

Many family members who care for loved ones with cancer do not feel adequately prepared for the caregiving tasks they assume and need help to make informed decisions about end-of-life care, according to a new study.

Cancer caregivers experience high levels of emotional stress. Many of them need to perform medical or nursing tasks without feeling fully prepared or trained to carry them out. The study findings were presented at the American Society of Clinical Oncology Palliative Care in Oncology Symposium in San Francisco.
