Reference excerpt

The National Wilms Tumor Study Group (NWTS) is a cancer research cooperative group in the United States formed to study a type of kidney tumor that affects children called Wilms' tumor. In 2001, NWTS merged with several other pediatric oncology cooperative groups to create the Children's Oncology Group (COG). However, the NWTS is still active in name today completing follow-up of the late effects of treatment for patients previously enrolled in its trials. The acronym NWTS is pronounced like the word "nitwits". The NWTS was formed in 1969 by member institutions from Children's Cancer Study Group (CCG), Southwest Oncology Group (SWOG), and CALGB, the latter two which later merged to form the Pediatric Oncology Group (POG). The NWTS was created with the purpose of improving survival of children with Wilms' tumor. NWTS studies were conducted at over 250 pediatric oncology treatment centers in the United States, Canada, and other countries. Approximately 70-80% of patients with Wilms' tumor were enrolled on NWTS treatment protocols, totalling 440 patients per year. NWTS ran five clinical trials, designated NWTS-1 to NWTS-5. The first four were randomized trials, whereas NWTS-5 was a clinical trial designed to look primarily at biologic prognostic factors and was not randomized. NWTS-5 was completed in 2003.

Worked examples

Example 1 — a first encounter with National Wilms Tumor Study Group

Start with the simplest possible case. Write down what National Wilms Tumor Study Group claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to National Wilms Tumor Study Group before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about National Wilms Tumor Study Group ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of National Wilms Tumor Study Group

In research: National Wilms Tumor Study Group appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses National Wilms Tumor Study Group in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: National Wilms Tumor Study Group is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cancer organizations based in the United States, Children's Oncology Group, Medical research institutes in the United States, so understanding it makes those chapters shorter.
In everyday life: Look for National Wilms Tumor Study Group outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
