The role of the saccomano technique in sputum cytopathologic diagnosis of lung cancer.

The Saccomanno technique of sputum preparation is widely used. This study evaluates the role of this preparation in conjunction with fresh smears in the diagnosis of lung cancer. All sputum samples from September 1973 to July 1975 showing atypia were randomized and negative controls added. The Saccomanno and fresh smears were evaluated independently and blindly and classified as negative, atypical, suspicious, or cancer. When each preparation was compared with the original diagnosis, the diagnostic accuracy for 55 squamous carcinomas was similar (fresh 95%, Saccomanno 86%) but significantly less in the Saccomanno preparations of 22 small cell carcinomas (fresh 100%, Saccomanno 24%) and 26 adenocarcinomas (fresh 96%, Saccomanno 52%). Four cases negative on fresh smears were suspicious or diagnostic of cancer on the Saccomanno slides. There were no cases of small cell carcinoma in which the Saccomanno preparations added information not available on the fresh smears. The authors conclude that in conjunction with fresh smears, the Saccomanno preparation may contribute to the diagnosis of non-small cell carcinomas but does not appear to aid in the diagnosis of small cell carcinoma.

Comparison of written-visual and microslide-screening test measures in cytotechnology.

A study was conducted to ascertain the relationships among different competence assessment methods for cytotechnologists. Of primary concern was the extent to which examinations using multiple choice questions, color plate photomicrographs and filmstrip formats measure abilities in common with or predict performance levels on a practical, job-sample-microslide examination format in gynecologic cytopathology. The majority of cytotechnologists who volunteered for these tests were trained in schools of cytotechnology approved by the Committee on Allied Health Education and Accreditation (CAHEA) of the American Medical Association (AMA). School training, certification by the International Academy of Cytology (IAC) and by the American Society of Clinical Pathologists (ASCP) and participation in current continuing education activities were all associated with relatively higher test scores. The filmstrips format was least consistent in reflecting these distinctions. Overall, participants' scores in each test correlated to varying degrees with their scores on all other tests. Combinations of certain formats appear to have limited potential as performance evaluation methods; some of their drawbacks are presented.
