Abstract
The chance of a curative reoperation is better in patients with an asymptomatic recurrence than in those with a symptomatic one. Pelvic recurrences are often detected by thorough physical examination. In general, however, the sensitivity of the clinical examination is Low, so that about 75%. of the patients have symptomatic recurrence when it is detected clinically. Serial examinations of CEA, however, seem at present time to be the best indication of recurrence. Thus, elevated serum CEA concentration seems to predict cancer recurrence correctly in 80-90%.
