Chemotherapy Statistics

Understanding Chemotherapy Statistics

If you have received and diagnosis of cancer, you are likely to do exhaustive research into the treatments available, and the results that each has in sending that cancer into remission.  As you read these reports, however, keep in mind that statistics can often be interpreted in more than one way.  Chemotherapy Statistics, for instance, often refer to the "response rate" involved in a patient's treatment, but this is not necessarily an indicator that the cancer is being eliminated.  Advanced tumors will often shrink in response to initial chemotherapy, only to experience rapid growth a while later.

There are always  a range of responses to any form of treatment. For cancer treatments, in particular, those responses have so much to do with individual's overall health, the state of their immunity systems, as well as the cancer they are battling.  Unfortunately, a final report of a treatment's response rate does not delineate these many factors.  There can lie the misunderstandings.  For instance, in many studies, the results can be inflated by excluding the number of patients who died during the course of treatment. Obviously, the treatment did not impact the survival rate of these cancer patients, but their lack of response to this treatment is not reflected in the findings.

In addition to the exclusion of subjects, Chemotherapy Statistics can be misleading because of the subjective view of the professionals who are assessing the treatment's results.  if an oncologist is invested in the success of a certain treatment, such as chemotherapy, he or she may unconsciously proclaim a patient's chances of survival as greater than a more objective provider.  The physicians involved in any particular study may have many interests, among them, professional and financial among them, which can unwittingly influence their opinions of a patient's response to treatment.

When examining Chemotherapy Statistics, it is important to bear in mind the sweeping nature of this drug treatment. It kills both healthy and diseased cells.  Therefore, another aspect to consider when viewing "results" is the often unreported factors of toxicity and quality of life during treatment.  These considerations should weigh as significantly as the "results" trumpeted throughout the medical journals. In the end, the decision for treatment lies in the hands of the patient and his or her family.
