The document discusses personalized cancer care, emphasizing targeted treatments that consider the unique genetic makeup of a patient's tumor. It highlights advancements in targeted therapies approved by the FDA, which have improved outcomes for various cancers and reduced side effects compared to traditional treatments. The document also outlines the importance of integrating molecular assessments into treatment plans while recognizing that targeted therapies are not a guaranteed cure and may come with their own limitations.
Personalized Cancer Care
- 1. Personalized Cancer Care: A Look at Targeted Treatments

- 4. Did you know? About 1,658,370 new cancer cases are expected to be diagnosed in 2015 compared to an estimated 1,665,540 cases in 2014.
- 5. Did you know? About 1,658,370 new cancer cases are expected to be diagnosed in 2015 compared to an estimated 1,665,540 cases in 2014. Survival statistics vary greatly by cancer types and stage at diagnosis. The 5-year relative survival rate for all cancers diagnosed in 2004-2010 was 68%, up from 49%, partly due to both earlier diagnosis of certain cancers and improvements in treatment. *According to American Cancer Society www.cancer.org American Cancer Society’s Cancer Treatment & Survivorship Facts & Figures 2014-2015 American Cancer Society’s Cancer Facts & Figures 2015 American Cancer Society’s Cancer Facts & Figures 2014
- 6. WHAT IS PERSONALIZED CANCER CARE?
- 7. Cancer is not one disease. It’s hundreds of different diseases.
- 8. Cancer is not one disease. It’s hundreds of different diseases.
- 9. Personalized cancer care is a way of approaching an individual’s treatment plan by looking at the genetic makeup and the biology of the patient’s tumor to identify the best treatment plan for the individual.
- 10. HOW DOES IT DIFFER FROM PRIOR CANCER CARE?
- 11. We’ve gained a better understanding of how each person’s tumor is unique and how each individual is unique.
- 12. Years ago there were really only three options for treatment: These could occasionally cure certain types of cancer in people but the side effects were not small. chemotherapy radiation surgery
- 13. Today doctors are matching patients much more specifically to types of treatments. By really going after what makes the cancer different than the person, researchers are seeing less side effects and better effectiveness for patients.
- 14. WHAT TARGETED CANCER TREATMENTS ARE CURRENTLY AVAILABLE? ARE MOST FDA APPROVED?
- 15. In the past, we’ve had drugs that treated general characteristics of the tumor cell. For instance, it was known that tumor cells grow fast and they divide fast. So agents were used that would non-specifically go after the dividing process of the cancer cell.
- 16. Targeted treatments, on the other hand, are now aimed at a specific target in the tumor’s cell. These specific targets are associated with the cancer process. Targeted treatments take advantage of the characteristics that make the cancer cells different from healthy cells.
- 17. Targeted cancer treatments are available for many different types of cancers. The number of drugs the FDA is approving now is happening at record-breaking speed.
- 18. WHICH CANCER TYPE IS MAKING THE BIGGEST STRIDES IN TERMS OF TARGETED THERAPY?
- 19. It’s interestingly spread out through most types of human cancers. The leukemias and other types of blood cancers have had a number of targeted drugs developed.
- 20. The FDA is working closely with the academic world, as well as with the private sector to make sure that effective drugs are getting developed and getting developed quickly.
- 21. Researchers are finding the same targeted therapy drug can work with several different types of cancer.
- 22. For example, brain, cervix and colorectal cancer are all being treated with the FDA-approved drug Bevacizumab.
- 23. In the past, because of the difficulty of developing drugs and the cost of the process, rare tumor types, such as giant cell tumor of the bone, were unfortunately often overlooked for clinical trial.
- 24. Now, because development is moving incredibly fast, agents and targeted therapies are being found that are effective at treating extremely rare tumor types.
- 25. This, in part, has been made easier by technology’s ability to link communities of people and find patterns to lead to new drug development. Cervical cancer, which has been historically difficult to treat, now has an FDA-approved targeted therapy. Ipilimumab was developed to treat melanoma. This type of drug targets the immune system to fight the cancer for us.
- 26. An entire disease has been turned around with these types of therapies and immunotherapy and has completely revolutionized doctors’ approaches to that disease.
- 27. HOW DO YOU USE TARGETED TREATMENTS TO EFFECTIVELY PERSONALIZE CANCER CARE?
- 28. In general, the practicing clinician has to: • be aware of the way the patient is presenting • the stage of the disease • the standard options available • the molecular genotype of the tumor • if the patient could match for a targeted therapy
- 29. Part of the clinician’s responsibility is to know these factors.
- 30. We have the ability to mix and match therapeutic approaches with the goal of optimizing response and minimizing toxicity.
- 31. The clinician’s job is to help interpret what is the molecular noise versus what is the meaningful target that can either put the patient on a clinical trial or identify them for standard care.
- 32. There’s a huge interest in doing DNA tests on tumors. The answer to cancer for roughly 20% of those people may be hidden in those genes, and understanding the gene code itself can be life- saving. However, that’s the minority of cases still.
- 33. What we know today may not necessarily be accurate six months from now. A couple of years ago there were no targeted treatments for ovarian cancer. Now there are several.
- 34. That’s why it is the role of the physician to be the expert in advising patients and looking at the patient as an individual.
- 35. I HEAR A LOT ABOUT NEW TESTS ON TUMOR DNA. SHOULD I HAVE THOSE?
- 36. The situation of the patient makes a big difference here. Plus, the tools used today might be different a few years from now. The tumor might change as well.
- 37. The question should be asked if a molecular analysis will change the course of treatment. Will it send patients to clinical trial? If it does, then it may be considered.
- 38. Molecular tumor boards involve bringing a number of experts into a room, looking at a patient’s results and determining as a team what they think is best for the patient and which one of the identified targets could be treated with an FDA- approved targeted therapy or a clinical trial. Along this topic, there has also been a shift toward molecular tumor boards.
- 39. WHAT ARE THE LIMITATIONS OF TARGETED CANCER TREATMENT?
- 40. We need to recognize that, although targeted therapy has been a boon for cancer treatment, it’s not necessarily a cure-all.
- 41. Tumor cells are clever… – they can develop resistance to targeted therapies – the tumor can disappear – the tumor can re-mutate There are a variety of responses from the cancer cell to survive even with the targeted therapy.
- 42. Targeted treatments are not without side effects. The advantage of targeted therapy is to find a subset of patients who will benefit, a subset of tumors to respond. That doesn’t mean they don’t have toxicity.
- 43. One more item to note is that many types of cancer can be treated with standard treatments, such as chemo and radiation. The goal of targeted therapy is not to completely defer from these standard therapies just because targeted therapy is the new talked-about thing. It’s really about taking the whole person into account, and that’s where the details really do matter.
- 44. WHERE CAN I GO TO FIND OUT MORE INFORMATION?
- 45. How do you use targeted treatments to effectively personalize cancer care? Reputable sites for accurate information on cancer statistics: American Cancer Society: www.cancer.org The National Cancer Institute: www.cancer.gov American Society of Clinical Oncology: www.asco.org Other reliable sources of information are professional nonprofit organizations within the specific cancer type. For instance, Ovarian Cancer National Alliance is an organization within ovarian cancer and a good source for information. Additionally, www.cancer.net has subgroup-specific disease information.
