From January 1, 1970, to December 31, 1985, 51 patients with stage IB (FIGO) carcinoma of the cervix with lymph node metastases were treated at the University Hospital, Groningen, The Netherlands. The survival rate was 54% and the average duration of follow-up was 78 months (range 47-132). Important clinical variables for survival were investigated retrospectively: the survival rate in patients with a single lymph node metastasis (with tumor confined to the node itself) (n = 23) appeared to be much better than that of patients with multiple node involvement and/or single nodes with extranodular tumor infiltration (n = 28); survival was 85 and 24%, respectively (P less than 0.001). The same applied to patients with only occult lymph node involvement: the survival rate in patients with occult involvement of the hypogastric, external iliac, or obturator nodes was 87% in 19 patients with a single metastasis and 53% in 15 patients with multiple node involvement (P less than 0.02). The survival rate in 8 patients with adenomatous histological components was 42%. In 42 patients with squamous cell carcinoma, the survival rate was 56%. This difference was not statistically significant. Treatment complications and the effect of treatment on the site of recurrence were investigated.
