So I have a summer research gig, but my PI has also given me the opportunity to work at my own pace on writing a review. The review will be on a type of cancer I know nothing about and an tissue I have not studied in organ systems yet. In general, what would be the best way to go about writing this review? I have a very recent review (2015) on the topic; I'm wondering if it is appropriate to use this as a template, use some of the same sources, and simply add new information that has become available?
Any advice would be greatly appreciated.
This is what I do, regardless of how much I know about the topic. I'm guessing by what you wrote that your mentor did not provide you an outline, which is unfortunate.
(1) Clarify if you are writing a "review" or a "systematic review." They are different. Everything after this will apply to a "review." If you are doing a systematic review, it's a whole different process.
(2) Figure out the journal that your review is being submitted to. Go to that journal, and pull out a couple of reviews on different subjects. Use these to template the format. Then download the "Author Instructions" for that journal, which will give you guidelines on word counts, number of tables/figures, number and format of references.
(3) Go to PubMed or Embase, and find several review articles that cover the same subject you are writing about. Nearly every topic already has a review article written on it. Read the articles, which will start to give you some idea of the the important things to discuss in your paper.
(4) Go to PubMed or Embase, and search for articles on the topic. Limit it to the last 10 years or so, since review articles are most valuable when they update people with current information. I generally try to find somewhere between 10-20 articles about the subject.
(5) After you read all that, you should start to have the shape of the paper taking form in your head. It will probably follow a pattern you would expect (Introduction, description, etiology, pathophysiology, treatment, prognosis). Write down your outline, and make notes under each heading of the main topics you want to discuss, and areas that you need to investigate further.
(6) Go back to PubMed or Embase, and start pulling references that specifically relate to each heading, or any questions that you jotted down. For example, for prognosis, you'll probably want some papers that discuss clinical trials and the mortality with various treatment protocols. That kind of thing. Remember that you need references for pretty much every factual statement that you make. Most of my reviews have had between 50-100 references total.
(7) Start writing.
Good luck!
