Drug Sensitivity Testing

What is Sensitivity Testing?

Chemo sensitivity testing takes a sample of tissue or fluid from the tumor itself and tests chemo therapeutic agents in a lab before a chosen agent or combination is introduced to the body. This allows an oncologist to better predict how a tumor will react to the specific protocols before prescribing them. If the therapy kills the cancer cells, the oncologist knows it will do the same once it is introduced to your body. If it does not, then that treatment is given a lower priority in favor of other, more effective treatments.

This is important because standard treatments often do not work, and because chemo therapeutic agents have harsh and toxic side effects that can also last long after the treatment is over. Prioritizing these choices helps you get on the right treatment and avoid unnecessary side effects from treatments that may not work.

Are there types of Sensitivity Testing?

Yes. Chemo sensitivity (or resistance) typically tests and prioritizes 7-21 chemotherapeutic agents that are commonly prescribed to the cancer indication. Results are usually available within 7-10 working days. On the other hand, a Drug Screening Panel (or organoids)  is also available, and tests over a hundred drug interactions with live tumor tissue. These tests include chemo therapeutic agents, targeted drugs and immunotherapy drugs to find the right combination of drugs and therapies to treat recurring or chemo-resistant cancers. Results are often available in 2 to 12 weeks.

Who is a good candidate?

Every patient can benefit from knowing how chemotherapy will affect their tumor before consenting to treatment. After all, there is nothing more disheartening than enduring the toxic side effects of chemo only to discover the cancer has not responded.

More specifically patients:

  • with aggressive disease or disease of unknown origin
  • with advanced stage cancer or metastasis
  • where the cancer has recurred
  • whose cancer is not responding to traditional treatments
  • with multiple treatment options
  • experiencing too many side effects from my current treatment
  • being told that there are no other treatment options available to me
  • that have or (or think they may have) developed resistance to their current treatment

Armed with live tumor tissue or fluid, your treatment team can customize a therapy that will offer you the best chance for recovery.

What is Drug Screening?

Drug screening tests hundreds of medications and therapies on your live cancer cells in a lab, and prioritizes the best choices instead of experimenting with the wrong drugs in your body. Not only are you able to avoid unfortunate side effects of certain therapies that may not work, but oncology teams can also determine which combination will best work and effectively shrink or eradicate the tumor.

Imagine having the confidence that you on the most effective treatment option.

How does Drug Screening work?

After preserving live cancer cells from your tumor, clinicians can test it against more than a hundred different drugs including chemotherapy agents, targeted medications and immunotherapy drugs. Some of these medications are experimental, or not approved for your specific indication, or only prescribed for tumors that are resistant to traditional chemotherapy. Drug screening helps prioritize the drug choices, tests experimental drugs, and identifies combinations that may prove more effective than single agents.

What is the difference between Chemo Sensitivity Testing and Drug Screening?

Chemo sensitivity typically tests and prioritizes 7-21 chemotherapeutic agents that are commonly prescribed to the cancer indication. Results are usually available within 7-10 working days.

Drug screening tests chemotherapy agents and tens of additional experimental medications and immunotherapy drugs to find the right drug or combination of for a particular tumor.

Who is a candidate for Drug Screening?

Every patient can benefit from prioritizing the drug choices and combinations to increase the likeliness of the treatment working. Since this test is not standard and covered by insurance, this test is more specifically appareling to patients:

  • with aggressive disease or disease of unknown origin
  • with advanced stage cancer or metastasis
  • where the cancer has recurred
  • whose cancer is not responding to traditional treatments
  • with multiple treatment options
  • experiencing too many side effects from my current treatment
  • being told that there are no other treatment options available to me
  • that have or (or think they may have) developed resistance to their current treatment

However, it is vital that live tumor is obtained for the testing to occur. That is why tumor banking is such an important part of your treatment. 

If I had cancer, additional testing is the approach I would want to take. We know that sensitivity testing show tumors respond to a drug that would likely not be predicted. Sensitivity Testing screens for hundreds of drugs and drug combinations– without exposing patients to toxic and potentially ineffective treatments.

Tumor Preservation

Your tumor is preserved in multiple formats for further study, immediately or at a later time. It is ideal for every cancer patient. Learn more about Tumor Preservation.

Chemo Sensitivity Testing

Tests which chemotheraputic agents will work on the tumor from day one, and which will not. Learn more about Chemo Sensitivity Testing.

Genomic Profiling

Identifies mutations on your tumor that help your oncologist prescribe targeted drugs based on your tumor's profile. Learn more about Genomic Profiling.

Drug Screening

Tests chemotherapy agents and tens of additional experimental and immunotherapy drugs to find the right combination for a particular tumor. Learn more about Drug Screening.

Personalized Vaccines

Immunotherapy to treat developed cancers (as opposed to preventative). It educates the immune system to attack your cancer cells. Learn more about Personalized Vaccines.

Adoptive T-Cell Therapy

Immunotherapy approach that attempts to boost the natural ability of the patient’s T-cells (killer cells) to attack and fight your cancer cells. Learn more about Adoptive T-Cell Therapy.
