. . . supporting research that improves cancer survival.

'I'm here for breast cancer. Why are you talking to me about my heart?'

Many physicians are not telling cancer patients about the cardiotoxicity risks of treatments and may not be fully aware of the dangers themselves. A new study reveals an urgent need to look after the hearts of these patients. 

"There was no mention that it could lead to heart disease. Would have been nice to know."

The growing number of cancer survivors and increasing number of over-65s needing chronic cancer therapy mean that the need for cardio-oncology services is rising. Heart failure caused by cancer therapy can occur up to 20 years after treatment. In 2012 over 32 million people worldwide were living with cancer.

"Depending on the type of chemotherapy and radiotherapy, between 1% and 25% cancer patients may develop heart failure due to cancer treatment," said study author Professor Robyn Clark, of Flinders University, Adelaide, Australia. "Risk also depends on cardiovascular risk factors such as smoking and obesity. Better monitoring of the heart and intervention before, during and after treatment can prevent or lessen the impact of this cardiotoxicity."

The researchers reviewed medical records of 46 randomly selected cancer patients with cardiotoxicity who attended one of three hospitals between 1979 and 2015. Just 11% were referred to a cardiologist before chemotherapy and less than half (48%) were referred to a heart failure clinic after cancer treatment. Almost 40% were overweight or obese, 41% were current or ex-smokers, 24% were regular consumers of alcohol, 48% had hypertension, and 26% had diabetes.
​
In a subset of patients, practice was compared before (1994-2011) and after (2012-2015) the 2012 European Society for Medical Oncology guidelines were published.3 Referral to a cardiologist before chemotherapy rose from 0 to 23% and conducting a baseline echocardiogram of the heart increased from 57% to 77%.

Could mouth rinse to detect HPV DNA predict the risk of head/neck cancer recurrence?

Researchers examined if a mouth rinse to detect human papillomavirus (HPV) DNA might be associated with helping to predict risk of recurrence of head and neck squamous cell cancer and death.

This study included 396 adults with head and neck squamous cell cancer of the mouth or throat, of which 202 patients had HPV-positive cancers. The adults were tested for the presence of HPV DNA with an oral rinse at various times. After completing cancer treatment, the repeated detection of HPV DNA identical to their tumor type in oral rinses was associated with a higher risk of cancer recurrence and death. The typical follow-up time of about two years in this study may have underestimated the associations between the persistence of HPV and cancer recurrence. More research is needed but these findings suggest HPV DNA may be a promising biomarker to understand cancer treatment response and future risk of progression.
