In Reply.—Dr Reynolds' letter is important because it represents what seems to be an increasing trend; the use of fine-needle aspiration of the thyroid in the community setting by an interested internist-endocrinologist with a high degree of success. This negates the previously published requirement of a high volume such as ten per week to maintain expertise, which we quoted in our article. Others should be encouraged to follow suit. As Reynolds states, however, expert pathologic interpretation is still a major requirement. The percentage cancer index in Reynolds second group of 85 patients was 50% (5/10 operated on) and would be considered good according to the survey in our report.
