Avastin is a antiangeogenic monoclonal antibody. It inhibits the tumors ability to recruit blood vesels for nutrition. CPT-11 or Camptosar Interrupts the DNA replication process resulting in cancer cell death.

Possible Avastin side effects:
Nosebleeds
Nosebleeds were usually minor and stopped on their own by holding a tissue to the nose
Call your doctor if you feel dizzy or faint or if the bleeding doesn't stop after 10 to 15 minutes
Hypertension (high blood pressure)
Standard oral medications were used to manage high blood pressure
Tell your doctor if you've had high blood pressure in the past
Proteinuria (too much protein in the urine)
Other side effects included weakness, pain, diarrhea, and leukopenia (a reduced white blood cell count)
Serious side effects you should know about
In clinical trials for colorectal cancer, a small percentage of people treated with Avastin in combination with chemotherapy experienced serious side effects, including gastrointestinal perforation (2%) and slow or incomplete wound healing (1%). In rare cases, these side effects have been fatal.
Patients taking Avastin with chemotherapy had a higher risk of stroke or heart problems compared with people taking chemotherapy alone. Talk to your doctor about these potential problems, especially if you are over 65 years old.
Possible CPT-11 side effects:
CAMPTOSAR may cause both "early" and "late" diarrhea. The early form happens within 24 hours of taking your chemo. It is often mild and goes away soon. The late form happens more than 24 hours after taking chemo. It can be very serious.
Your doctor may suggest that you take a drug called Imodium® A-D. It is also called loperamide. Be sure to take it just as your doctor says. This dose might be different than what is on the box. It will help control diarrhea caused by chemo. Your doctor may also choose to use an antibiotic.
In rare cases, blocked bowel, colon problems, or liver disease have occurred. Always tell your doctor if you have side effects.
CAMPTOSAR can prevent the body from making enough blood cells. That means your white blood cells may get too low. If so, your doctor may decide you need a drug that helps blood cells grow.
Some people should be watched closely by their doctor while taking CAMPTOSAR. They include those who: • are over age 65
• received radiation in the pelvis or stomach
• have trouble carrying out daily tasks due to their cancer
• have 2 copies of the same gene (UGT1A1* 28)
When you take CAMPTOSAR, your doctor may give you a drug that helps fight vomiting and diarrhea. This drug is called atropine.
In some cases, CAMPTOSAR may cause heart and blood clotting problems. Doctors do not know for sure why this happens.
************************************************
The first dose of Avastin will probably take 90 minutes. The second 60 minutes and third 30 minutes. 30 minutes thereafter. Same dose each time.
Because of the increased risk of bleeding there should be no surgery within two weeks of administration. Manufacturer says 28 days but the agreed upon time is two weeks.
That's all for now.
Is your insurance company going to pay for this?
If so, who do you have?
