Vaccines in Cancer Care and Risk Reduction January 9, 2019

For our first chat of 2019, we had twenty-eight participants discussing Vaccines in Cancer Care and Risk Reduction. You may find the transcript here and additional analytics here.

Some responses to our questions may be found below.

T1: What vaccines are available before you develop cancer to reduce your risk? Are there different types? 
  • T1 The #HPV vaccine is cancer prevention for six cancers-cervical, vaginal, vulvar, penile, & oropharyngeal. #gyncsm
  • T1: Cancers that are caused by viruses can be vaccinated against. HPV vaccine protects against cervical and other HPV-related cancers. The HepB vaccine can help protect against liver cancer
  • the #HPVvaccine has been available since 2006 -- initially it offered protection against HPV16 and HPV18, the types of HPV that causes 70% of #cervicalcancer #gyncsm
  • the FDA approved Gardasil 9 in 2014 -- which protects against another 20% of the most dangerous subtypes of #HPV #gyncsm 
T2: What cancers can be caused by HPV? How does the HPV vaccine reduce the risk of HPV-related cancers?
  • T2 Cervical, vaginal, vulvar, anal, penile, & oropharyngeal cancers are caused by HPV. Every year in the US, HPV causes 33,700 cancers in men and women
  • #HPV can cause #cervicalcancer and some types of ear-nose-and-throat, vulvar, vaginal, penile, and anal cancer. The CDC recently release a report about trends in HPV-related cancers. #gyncsm cdc.gov/mmwr/volumes/6…
  • T2 -- interestingly, in recent years oropharyngeal cancers are now the most common type of HPV-related cancer. #HPV #gyncsm
  • T2 The HPV vaccine protects against an HPV infection-persistent infection can lead to cell abnormalities & cancer.
  • T2: It takes a long time for a persistent HPV infection to cause cervical disease and pre-cancer. The vaccine helps keep the body from being infected after exposure. Approx 80% of people are exposed to HPV at some point in their life
  • It's better to get vaccinated before exposure to #HPV - that way your body is already immune!
  • A2 from @cochranecollab Among women aged 15 to 26 years, vaccines reduced the risk of cervical precancer associated with HPV16/18 from 341 to 157 per 10,000. HPV vaccination reduced also the risk for any precancer lesions from 559 to 391 per 10,000.
T3: What are the current U.S. recommendations for HPV vaccination? Who should get vaccinated, when and how many doses? T4: What are cancer treatment vaccines? How do they work? When are they used - after front-line? T5: In which gynecologic cancers are treatment vaccines being studied? Has there been progress in this area? Additional resources shared during the chat may be found at the end of this post. 

Be sure to join us next month on February 13, 2019 at 9pm ET for our chat "Getting Into a Clinical Trial". 

You can also join us for a collaborative chat across all #cancer communities presented by #LCSM this Thurs Jan 10th at 8pm ET/5pm PT on "Immunotherapy: What Patients Need to Know". More here: https://lcsmchat.com/2019/01/06/lcsm-chat-2019-01-06-immunotherapy-what-patients-need-to-know/
