Invasive squamous cell carcinoma of the uterine cervix. VIII. Survival and malignancy grading in patients treated by irradiation in Lund 1969-1970.
The correlation between certain prognostic factors and the 10-year survival/lethality rate was analysed in 168 patients with invasive squamous cell carcinoma of the uterine cervix stage I A-II B treated by radiation therapy from 1969 through 1970. These factors included a malignancy grading system (MGS) consisting of 8 items: structure (P1), differentiation into cell type (P2), nuclear polymorphism (P3), mitosis (P4), mode of invasion (P5), stage of invasion (P6), vascular invasion (P7), and host-cellular response (P8). Histologic differentiation (1) and differentiation into cell type (11), the patient's age, the year of admission, the clinical stage (FIGO), and irradiation were also analysed. Many of these factors were correlated to the prognosis. However, the MGS system was superior as a predictive factor. Patients with a low MGS score had an extremely good survival rate at both the 5- and 10-year controls. The patients with a high MGS score had approximately 55 per cent lethality at 10 years. The MGS was significantly superior to each separate item as well as to each predictive factor (p less than 0.05). Further, no other important predictive factor could be identified after the MGS had been included in the multivariate analyses.
