New ‘lab-on-a-chip’ could revolutionize early diagnosis of cancer

“Exosomes are minuscule membrane vesicles — or sacs — released from most, if not all, cell types, including cancer cells,” said Yong Zeng, assistant professor of chemistry at the University of Kansas. “First described in the mid-’80s, they were once thought to be ‘cell dust,’ or trash bags containing unwanted cellular contents. …

High alcohol intake linked to heightened HPV infection risk in men

And habitual drinking is known to increase susceptibility to bacterial pneumonia, septicaemia, tuberculosis and viral hepatitis. The researchers therefore wanted to find out if there was any association between drinking patterns and susceptibility to HPV infection. They included 1313 men who were already taking part in the US arm of the HPV in Men (HIM) study, an international study that is tracking the natural history of HPV infection in men. …

Nivolumab shows signs of superior response rate compared to standard chemotherapy in advanced melanoma

“Previously-treated advanced melanoma patients have limited options,” says the study’s principal investigator, Professor Jeffrey Weber, Director of the Donald A. Adam Comprehensive Melanoma Research Center of Excellence at the Moffitt Cancer Centre, Tampa, Florida. Nivolumab is an antibody in a class of drugs called ‘checkpoint inhibitors’, that act to relieve a critical brake placed on the immune system by the tumour itself. The drug then reinvigorates patients’ anti-tumour immune response and promotes shrinkage of the tumour…

Skirt size increase linked to 33 percent greater postmenopausal breast cancer risk — ScienceDaily

The researchers base their findings on almost 93,000 women taking part in the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) in England. The women were all aged over 50, had gone through the menopause, and had no known breast cancer when they entered the study between 2005 and 2010. At enrolment they provided detailed information on height and weight (BMI); reproductive health; fertility; family history of breast and ovarian cancer; and use of hormonal contraceptives and HRT, all of which influence breast cancer risk. They were also asked about their current skirt size, and what this had been in their 20s. …

Improved risk identification will aid fertility preservation in young male cancer patients

By clarifying which patients are at highest risk for reduced sperm production as adults, researchers expect the findings to eventually increase use of pre-treatment fertility preservation methods such as sperm banking. The study involved drugs called alkylating agents that are widely used to treat a variety of pediatric cancers. …

Mobility in cancer patients with malignant spinal cord compression

Malignant spinal cord compression (MSCC) is a complication of metastatic cancer mostly with bone involvement that occurs when a tumor’s secondary deposit presses on the spinal cord and nerves. This pressure exposes patients to neurological damage that can result in pain, loss of muscle strength and function of one or more of the senses. In some cases, the neurological damage can lead to paralysis of the entire body below the neck or paralysis of one or more limbs. …

Patients who never smoked or who quit smoking have lower risk of developing secondary cancers

The analysis studied the association between patients’ smoking histories and their risks of developing SPLC, which is defined as a new lung cancer unrelated to the initial tumor based on histology and location in the lung. The study analyzed 1,484 patients (372 current smokers, 1,014 former smokers and 98 never smokers) who underwent surgery, with or without adjuvant chemotherapy or radiation therapy, for stage I-IIIA NSCLC at Duke University Medical Center between 1995 and 2008. Baseline covariates and oncologic outcomes including local control (LC), development of distant metastases (DM), overall survival (OS) and rates of SPLC were assessed. …
