study involving 310 samples of oral cancer, both malignant and pre-malignant, comprising both males and females, more than 60 per cent of the nearly 197 samples reported the presence of HPV virus in oral cavity.
"This study was conducted by collecting either oral swabs or biopsy reports of the 310 patients who had reported either malignant stage or pre-malignant stage of oral cancer. We had found the presence of HPV virus in 197 patients," C K Panda, head of the research team, CNCI, said.
Out of these 197 patients which reported presence of HPV virus, HPV 16 virus was found in 180 patients and the rest of the patients are reported to have HPV 18 virus in oral cavity.
Panda noted that in a micro study of the 155 samples of 197 samples which reported the presence of HPV virus, it has been found that HPV constitutes the sole carcinogenic agent in 26 per cent of cases.
Tobacco comes out the sole cancer causing agent in 32 per cent cases, said Panda.
Genital and oral hygiene is the best way to avoid transmission of HPV virus, Basu said.
