Reference excerpt

Kanematsu Sugiura (1890 – October 21, 1979 in White Plains, New York) was a cancer researcher who spent his career at the Memorial Sloan-Kettering Cancer Center. A pioneer in cancer research", he completed over 250 papers before his death. Sugiura received a number of awards and prizes throughout his life, and retired from the center in 1962. He is perhaps best known for his work on laetrile, a controversial alternative cancer treatment, which he was convinced had a palliative effect on certain mice tumors. The report that was released by Sugiura of his findings of the experiment are as follows: The results clearly show that Amygdalin (Laetrile) significantly inhibits the appearance of lung metastasis in mice bearing spontaneous mammary tumors and increases significantly the inhibition of the growth of the primary tumors.... Laetrile also seemed to prevent slightly the appearance of new tumors.... The improvement of health and appearance of the treated animals in comparison to controls is always a common observation.... Dr. Sugiura has never observed complete regression of these tumors in all his cosmic experience with other chemotherapeutic agents.

Laetrile controversy In 1972, Memorial Sloan-Kettering Cancer Center board member Benno Schmidt convinced the hospital to test laetrile in order to assert its ineffectiveness "with some conviction". Sugiura found that laetrile inhibited secondary tumors in mice, without destroying the primary tumor, but in a blind test was unable to conclude that laetrile had anticancer activity. The initial positive results were not published because, in the words of Chester Stock, Sugiura's supervisor, "it would have caused all kind of havoc." Nevertheless, they were leaked in 1973, causing a stir. Consequently laetrile was tested on 14 tumor systems, and a Sloan-Kettering press release concluded that laetrile showed no beneficial effects. Three other researchers were unable to confirm Sugiura's results. Mistakes in the Sloan-Kettering press release were highlighted by a group of laetrile proponents, led by Ralph W. Moss, former public affairs official of Sloan-Kettering hospital, who was fired when he announced his membership in the group. These mistakes were considered inconsequential, but Nicholas Wade in Science noted that, "even the appearance of a departure from strict objectivity is unfortunate." The results of all of the studies were published together in the Journal of Surgical Oncology.

Worked examples

Example 1 — a first encounter with Kanematsu Sugiura

Start with the simplest possible case. Write down what Kanematsu Sugiura 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 Kanematsu Sugiura 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 Kanematsu Sugiura 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 Kanematsu Sugiura

In research: Kanematsu Sugiura 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 Kanematsu Sugiura 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: Kanematsu Sugiura is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1890 births, 1979 deaths, Alternative cancer treatment advocates, so understanding it makes those chapters shorter.
In everyday life: Look for Kanematsu Sugiura 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.
