Understanding Cancer Research Study Design and How to Evaluate Results

Doctors and scientists usually strive to find answers for complicated situations, such as how to prevent and treat cancer. The work of researchers is to come up with answers to questions in different ways. No study is perfect hence answers can vary due to certain drawbacks. The study design is critical when it comes to understanding answers matching your situation. 

Let’s find out the 2 main types of cancer research studies:

  • Experimental studies

The process commences by identifying groups of people, where the first group is given the treatment whereas the second group does not get the treatment. The group that does not receive the intervention is known as the control group. Researchers then select a member from each group to check how cancer starts and spread within a group of people. Such studies also help researchers to come up with the latest imaging techniques.

  • Observational studies

This method of clinical research involves, studying a group of people in its natural settings and equally, there is no provisioning for any innervations by the researchers, such as checking on a patient’s weight and other personal information. Few members are selected from each group. The main purpose of this group is to check the results of the two groups in terms of how cancer starts and spread among a community.

In experimental studies, https://www.agilent.com/en/product/molecular-spectroscopy enables chemical lab tests to be carried out. Note that, however good the experiment is, the accuracy of these test results and their interpretation are the most important elements of an experiment. Following are the checklist used to evaluate research studies.

Here are some tips for finding out the quality of a research study:

  • Peer-review the journal

An independent team should look and approve the design and method used to carry out the research studies.

  • Research duration and samples involved

Studies conducted on a sample by several people should generally produce the same results with repeated.

  • Phases of studies for the new treatment

Generally, phase I and II show how safe the clinical trials are on a sample studied, and since these are the study phases, they tend to have a smaller sample as compared to phase III. A phase III, the numbers of samples rise as this is the treatment phase.

  • Does the study support and contradict the current research?

Researchers need to validate study results before the research can be officially accepted in a medical field.

  • Pay attention to study conclusion that deviates from the results

Every study forms part of the bigger research picture, and basically, there should be no major deviations in the medical practice due to changes that occur on single research done.

Coming up with a solution in the medical field requires lots of inputs from both the doctors and the researchers, at agilent.com/en/product/molecular-spectroscopy, a lot of research work and chemical lab test is carried out by researches to come up with credible medical solutions. By carefully, evaluating research work done by an independent body will provide a credible solution.
