Malignancy grading in squamous carcinoma of uterine cervix treated by surgery.

Some morphological patterns (histological type, vascular invasion, depth of invasion, lymphocytic infiltrate, mode of spread, necrosis) in 125 cases of squamous cervical carcinoma treated by surgery were analysed and graded in order to identify a histoprognostic score. Clinical data on F.I.G.O. stage, modality of surgical treatment, age, hormonal state (pre- or post-menopause) and 5-year survival were known for each patient. Two groups (low and high malignancy) were disclosed, and the difference of survival rate between the 2 was highly significant (P less than 0.001).
