Arsenic used for centuries to treat hematological malignancies is still used in cancer patients.

All forms of arsenic are a serious risk to human health. The arsenic is a hazardous substance and also classified as carcinogenic. Arsenic makes arsenic trioxide with concentrated sulfuric acid. Arsenic has been used in Manchuria (Asia) 2000 years ago, it was only first reported as a treatment for leukemia in the Western literature in 1878.; it later became a popular treatment for chronic myeloid leukemia in 1930. The compound arsenic trioxide has been under investigation in China as an anticancer treatment since 1970. Chinese investigators first reported responses to intravenous arsenic trioxide in patients with acute pro-myelocytic leukemia (APL) in 1992. Arsenic trioxide is approved and used to treat APL. More specifically, this medication is given to patients who have not responded to a different initial treatment, or whose cancer has recurred. This medication is given has an intravenous injection. The injections usually take 1 to 2 hours, but may be given more gradually if side effects occur during the infusion. Arsenic trioxide is usually given once a day for several consecutive days.

Australia could become the first country to eradicate cervical cancer, according to an announcement from the International Papillomavirus Society.

New research, published on Sunday, reveals that Australia’s free HPV vaccine program in schools has led to a dramatic decline in future cervical cancer rates. Within 40 years, the number of new cases is projected to drop to “just a few”, professor Suzanne Garland from the Royal Women’s Hospital, who led the research, said.

HPV (human papillomavirus) is a sexually transmitted infection that causes 99.9% of cervical cancers. In 2007, the federal government began providing the vaccine for free to girls aged 12-13 years, and in 2013, it extended the program to boys. Girls and boys outside those ages but under 19 can also access two doses of the vaccine for free. In 2016, 78.6% of 15-year old girls and 72.9% of 15-year old boys had been vaccinated.

As a result, the HPV rate among women aged 18 to 24 dropped from 22.7% to 1.1% between 2005 and 2015.

 

Association between hepatitis C virus and oropharyngeal cancer.  

Hepatitis C virus (HCV) infection is associated with hepatocellular carcinoma and non-Hodgkin’s lymphoma. In 2009, MD Anderson were the first to report unexpectedly large number of patients with oropharyngeal cancers. The prevalence of HCV seropositivity in oropharyngeal cancer patients is 14.0%. In a recently study of survival in patients with oropharyngeal cancer, the researchers reviewed the records of patients who were tested for HCV at MD Anderson from 2004 to 2015. The 5-year overall and progression-free survival rates were significantly higher for HCV-negative patients than for HCV-positive patients. Their findings could change standard practices for HCV screening and treatment in patients with cancers of any type.
