A new study published in Cancer suggests that infertile men are 2.6 times more likely to be diagnosed with high-grade prostate cancer than fertile men. The research found no association between the number of children a man has and his risk for prostate cancer, but rather focused on male fertility as a potential risk factor.
Researchers have discovered that pre-treating mice with noscapine before injecting them with prostate cancer cells resulted in tumor growth rates being two-thirds smaller and lung metastasis rates being 80% less. The study suggests that noscapine may offer significant benefits in the management of prostate cancer as a preventive measure.
Magnetic resonance-guided focal therapy offers a new treatment choice for patients with recurrent prostate cancer, providing an alternative to radiation therapy and hormone manipulation. The procedure involves tailored treatment modality and duration based on lesion size and location, preserving sexual and urinary function.
A study found that increasing the radiation dose for prostate cancer treatment did not lead to increased long-term side effects. Patients reported minimal distress from chronic symptoms, with many considering their quality of life 'normal' despite experiencing symptoms. The results suggest that patients may adapt to treatment and exper...

A randomised trial found that medroxyprogesterone acetate is significantly more effective than venlafaxine at reducing hot flushes in men treated with androgen suppression therapy. Cyproterone acetate was also effective, but medroxyprogesterone is recommended as the standard treatment due to its fewer side effects.
A Mayo Clinic study found that routine annual evaluation of prostate growth is not a reliable predictor for prostate cancer development. However, if PSA levels are rising quickly, a prostate biopsy is recommended to determine if prostate cancer exists.
Researchers found that parathyroid hormone can elevate PSA levels in healthy men, leading to unnecessary biopsies and treatment. The study aims to refine the prostate cancer screening test to better differentiate between those who need a biopsy and those who may be spared.
Researchers at Yale University developed synthetic molecules that enhance the body's immune response to HIV and prostate cancer cells. The molecules work by binding to antibodies and proteins on infected cells, triggering an immune response and preventing infection.
Men with prostate cancer who experience PSA rise within 18 months of radiotherapy are at higher risk of developing spread and dying from their disease. The time between treatment and PSA recurrence has been shown to be a significant predictor of cancer-specific mortality.
A new study by Henry Ford Hospital found that a patient's socioeconomic status has no effect on their outcome following curative radiation therapy for prostate cancer. The study analyzed data from 788 patients and found that all patients, regardless of race or income, had similar survival rates and biochemical control rates.
Research led by Ohio State University found that aggressive prostate cancers have small, irregular blood vessels, while slow-growing tumors have more normal-appearing vessels. This study suggests using tumor blood vessel architecture to guide therapy and potentially improve long-term survival for patients.
A study presented at the American Society for Radiation Oncology (ASTRO) found that hypofractionated radiation treatment is more effective in stopping cancer from growing in high-risk prostate cancer patients compared to standard radiation therapy. The new treatment also had no increased risk of negative side effects, making it a valua...
A new study found that a shorter, five-week course of hypofractionated radiation is as effective as standard radiation therapy in reducing prostate cancer recurrence. The treatment delivered higher doses of radiation in fewer sessions, resulting in no significant difference in cancer recurrence or side effects between the two groups.
Researchers found that men with lower cholesterol levels had a 59% lower risk of developing high-grade prostate cancers, which tend to grow and spread rapidly. The study suggests that targeting cholesterol metabolism may be one route to treating and preventing the disease.
