xColorectal cancer (CRC) is common, affecting >40,000 people a year in the UK. Most cancers are sporadic but a few, such as those occurring at a younger age, have a clear genetic basis. Most are situated in the rectum or rectosigmoid and cause rectal bleeding, often with a looser or more frequent stool. Right-sided cancers typically result in anaemia, because the blood in the stool is occult and unnoticed by the patient. Almost all symptoms of malignancy can also be caused by benign disease. Diagnosis relies on luminal imaging, with colonoscopy being the gold standard.
In June 1948, Sidney Farber reported promising results in treatment of early childhood leukemia. Based on anecdotal evidence that children with acute leukemia worsened if they were given folic acid, he worked on blocking folic acid metabolism. His team gave 16 infants and children with acute lymphoblastic leukemia a folic acid inhibitor, aminopterin—10 showed improvement by clinical and hematologic parameters after three months.[11] In his article, Farber advised receiving the results cautiously: "It is again emphasized that these remissions are temporary in character and that the substance is toxic and may be productive of even greater disturbances than have been encountered so far in our studies," he wrote. "No evidence has been mentioned in this report that would justify the suggestion of the term 'cure' of acute leukemia in children."
