Immunotherapy may add years for prostate cancer patients

Some men with advanced prostate cancer who have exhausted all other treatment options could live for two years or more on immunotherapy, a major clinical trial has shown. Researchers found that a small proportion of men were 'super responders' and were alive and well even after the trial had ended despite having had a very poor prognosis before treatment. The study found that one in 20 men with end-stage prostate cancer responded to the immunotherapy pembrolizumab -- but although the number who benefited was small, these patients sometimes gained years of extra life. The most dramatic responses came in patients whose tumors had mutations in genes involved in repairing DNA, and the researchers are investigating whether this group might especially benefit from immunotherapy.

Higher omega-3 levels does not increase prostate cancer risk

Omega-3 shown to protect against heart disease-related death, without increasing prostate cancer risk ---> Should you take omega-3 pills? Or try to have two to servings of omega-3 rich fish a week, as the American Heart Association recommends? It may seem a bit murky if you follow headlines about nutrition and health. That's why researchers at the Intermountain Healthcare Heart Institute continue to research the potential benefits and risks of this popular supplement, especially when it comes to prostate cancer risk and heart health. In one study, the Intermountain research team identified 87 patients who were part of the Intermountain INSPIRE Registry and had developed prostate cancer. These patients were also tested for plasma levels of docosahexaenoic acid (DHA) and eicosapentaenoic acid [...]

Researchers identify new factors that may help reduce prostate cancer risk

Men with higher levels of 'free' testosterone and a growth hormone in their blood are more likely to be diagnosed with prostate cancer, according to research presented at the 2019 NCRI Cancer Conference. Other factors such as older age, ethnicity and a family history of the disease are already known to increase a man's risk of developing prostate cancer. However, the new study of more than 200,000 men is one of the first to show strong evidence of two factors that could possibly be modified to reduce prostate cancer risk. The research was led by Dr Ruth Travis, an Associate Professor, and Ellie Watts, a Research Fellow, both based at the Nuffield Department of Population Health, University of Oxford, UK. Dr Travis said: [...]

Researchers aim for a paradigm shift in prostate cancer diagnosis

In combination with the current prostate specific antigen (PSA) test, the new test could help men avoid unnecessary and invasive biopsies, over-diagnosis and over-treatment. Prostate cancer is the most common cancer in Western men, with 1.3 million new cases being diagnosed each year worldwide. It is currently detected using a blood test that measures PSA levels. Although it provides early diagnosis, the PSA blood test has a low specificity (high false positives) with about 75 per cent of all PSA positive results ending up with negative biopsies that do not find cancer. When a high PSA level in the blood is detected, the patient undergoes a tissue biopsy of the prostate gland, which is invasive and carries a significant risk of bleeding and [...]

Prostate cancer risks may be lowered by mushroom consumption

A new study published in the International Journal of Cancer found an inverse relationship between mushroom consumption and the development of prostate cancer among middle-aged and elderly Japanese men, suggesting that regular mushroom intake might help to prevent prostate cancer. A total of 36,499 men, aged 40 to 79 years who participated in the Miyagi Cohort Study in 1990 and in the Ohsaki Cohort Study in 1994 were followed for a median of 13.2 years. During follow-up, 3.3% of participants developed prostate cancer. Compared with mushroom consumption of less than once per week, consumption once or twice a week was associated with an 8% lower risk of prostate cancer and consumption three or more times per week was associated with a 17% lower [...]

The Mighty Cancer Fighting Properties of Feverfew

Researchers at the University of Birmingham have shown that it's possible to produce a compound with anti-cancer properties directly from feverfew -- a common flowering garden plant. The team was able to extract the compound from the flowers and modify it so it could be used to kill chronic lymphocytic cells in the laboratory. Feverfew is grown in many gardens, and also commonly sold in health food shops as a remedy for migraine and other aches and pains. The compound the researchers were investigating is called parthenolide and was identified by scientists as having anti-cancer properties several years ago. Although available commercially, it is extremely expensive with poor "drug-like" properties and has not progressed beyond basic research. Researchers were able to show a [...]

Cancer survival rate improving due to advances in treatment and early detection

There were more than 16.9 million Americans with a history of cancer on January 1, 2019, a number that is projected to reach more than 22.1 million by 2030 based on the growth and aging of the population alone, according to estimates from Cancer Treatment and Survivorship Statistics, 2019. The report is produced every three years by the American Cancer Society in collaboration with the National Cancer Institute to help the public health community better serve this growing population. It appears in CA: A Cancer Journal for Clinicians, with a companion consumer edition published as Cancer Treatment and Survivorship Facts & Figures. The number of cancer survivors continues to increase in the United States even as incidence rates are stable in women and declining [...]

Vitamin D taken for 3 years may help cancer patients live longer

New findings suggest that the vitamin carries significant benefits other than just contributing to healthy bones and were presented at the American Society of Clinical Oncology annual meeting on June 3, 2019. In the United States, cancer is the second leading cause of death, according to the Centers for Disease Control and Prevention. "Vitamin D had a significant effect on lowering the risk of death among those with cancer, but unfortunately it didn't show any proof that it could protect against getting cancer," said Tarek Haykal, a lead author on the study and an internal medicine resident physician at Michigan State University and Hurley Medical Center in Flint, Michigan. The researchers looked at data related to disease prevention from more than 79,000 patients in [...]
