Metastatic adenocarcinoma

My fiancee was diagnosed with metastatic adenocarcinoma (likely of the esophagus) just last week.
We would like to get him on ozone therapy as soon as possible and I have looked through the posts on the subject to find a good generator to buy for this.

A couple of the links were dead ends but I did have success with this one: http://www.promolife.com/cart/ozone-therapy/ozone-generators/o3elite-professi...

Would this be one that we could use for rectal insufflation?

We have also explored getting a Rife machine, but he has had a knee replacement and I don't know if that makes rife therapy a bad idea for him. I have found conflicting opinions on this matter.

Do you have an opinion on which therapy would be best for this type of cancer?
Also, would this cancer respond well to the herbs that you recommend in your cancer write up?

Are you available for consultations over the phone?

Thank you, James!
