Anal Cancer Survival Poorer Among Patients Living in Areas of Poverty

US residents who have anal cancer and live in areas of poverty have worse survival than those who live in more affluent areas, revealed research.

According to the researchers, squamous cell carcinoma of the anus (SCCA) accounts for 8,200 new cancer cases and more than 1,000 cancer-related deaths in the US annually.

‘Anal cancer patients living in low median household income areas are at an increased risk of early death.’

For the study, published in the journal Cancer, researchers examined whether area-based median household income predicts survival of patients with SCCA.

Their analysis included 9,550 patients with SCCA from 2004-2013 listed in the US Surveillance, Epidemiology, and End Results registry.

Socio-economic status was defined by census-tract median household income level, and divided into quintiles.

Quiz on Anal Cancer
Anal cancer is relatively a rare type of cancer that occurs in the anal canal. The anal canal is a short passage that connects the rectum to the outside of the body from where the stool is passed.

The researchers found that patients living in areas with lower median household income had worse overall survival and cancer-specific survival compared with those in highest income areas.

From the lowest to the higher income levels, the risk of dying was 32 per cent, 31 per cent, 19 per cent and 16 per cent higher for patients when compared with patients in the very highest quintile of median household income.

More Accurate, Low-Priced Genetic Test Coming Up for Anal Cancer
Epigenetic testing tool is a new genetic test being developed to find the lesions and treat the patient who are at a high risk of anal cancer.

When considering only deaths due to cancer, increased risks ranged from 34 per cent down to 22 per cent for the lowest to higher incomes.

Other factors such as older age, black race, male gender, unmarried status, earlier year of diagnosis, higher grade, and later stage were also associated with worse cancer-specific survival.

New Study on Connection Between Anal Cancer and Human Papillomavirus
A study demonstrating a connection between anal cancer and HPV infection has been published by researchers at Women & Infants Hospital, a Care New England hospital.

"To provide high quality healthcare for all, it will be important to get a better understanding of the factors limiting the successful treatment of anal cancer," said co-author of the study, Daniel Becker from NYU Langone Medical Center.
