Evaluation of radiocurability in uterine cervix cancer with a simple cytological test.

Value of karyopyknotic index (KPI) was estimated in a series of 95 radiation treated uterine cervix cancer patients. The patients were divided into two groups according to the age and the menstrual history. More than 10% of the mature squamous cells exhibiting pyknotic nucleus after radical treatment, were indicative of persistent malignant growth. Conversely, a decrease in the KP cells under 10% after treatment was considered a favorable prognostic omen. Our results also imply that a high KPI value before treatment signalizes a better prognosis.
