Insulin potentiation therapy

Insulin potentiation therapy is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Insulin potentiation therapy rather than just read about it. In short: Insulin potentiation therapy (IPT) is an unproven alternative cancer treatment using insulin as an adjunct to low-dose chemotherapy. It was promoted by a paper in the controversial and non-peer reviewed journal Medical Hypotheses.

Reference excerpt

Insulin potentiation therapy (IPT) is an unproven alternative cancer treatment using insulin as an adjunct to low-dose chemotherapy. It was promoted by a paper in the controversial and non-peer reviewed journal Medical Hypotheses. It is not an evidence-based cancer treatment, and the costs of IPT are not covered by health insurance. According to Quackwatch, "Insulin Potentiation Therapy (IPT) is one of several unproven, dangerous treatments that is promoted by a small group of practitioners without trustworthy evidence that it works."

History It was developed by Donato Perez Garcia, MD in 1930. Originally, Garcia targeted syphilis, and later tried the treatment for chronic degenerative diseases and some types of cancer.

Method Generally, a dose of insulin is injected into a vein, followed by a much lower dose of a chemotherapy drug. Then sugar water is injected to stop the hypoglycemia (low blood sugar) caused by the insulin injection.

Efficacy IPT has not been proven to work. Lab research indicates that there is not even a theoretical possibility of it being an effective treatment for most cancers. Research over the decades has proved that most cancers grow when exposed to more insulin. One study of men with prostate cancer showed that survival was significantly shorter (11 months for men who received IPT vs 18.9 months for men on standard treatment). A second small trial showed that women with metastatic breast cancer were less likely to see short-term disease progression if they received IPT with low-dose methotrexate than if they received either insulin alone or low-dose methotrexate alone. (This study did not compare IPT against any of the proven multi-drug chemotherapy regimens.)

Adverse effects The immediate risk is hypoglycemia. The main risk is that the person will die from cancer because IPT does not work. The use of lower than normal doses of chemotherapy can cause drug resistance, which could make future treatment at standard, proven doses ineffective. For some cancers, especially breast and colon cancers, insulin may promote tumor growth.

Mechanism of action Two main ideas about how it might work have been proposed over the years. The first idea, which has been proven wrong, is that insulin makes cells more permeable, so that the chemotherapy drugs are absorbed faster into cells. The other idea is that insulin might cause the cells to start dividing, which makes them more susceptible to destruction of many cytotoxic chemotherapy drugs.

Cost Costs run up to US$2,000 per treatment session. Multiple sessions are normal. One business charges US$50,000 for the first two months. Patients pay the full cost out of pocket, because it is an unproven therapy that is not covered by health insurance.

Worked examples

Example 1 — a first encounter with Insulin potentiation therapy

Start with the simplest possible case. Write down what Insulin potentiation therapy 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 Insulin potentiation therapy 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 Insulin potentiation therapy 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 Insulin potentiation therapy

In research: Insulin potentiation therapy 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 Insulin potentiation therapy 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: Insulin potentiation therapy is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alternative medical treatments, Experimental cancer treatments, Pseudoscience, so understanding it makes those chapters shorter.
In everyday life: Look for Insulin potentiation therapy 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.
