Carcinoma of the uterine cervix stage IB and IIA: results of postoperative irradiation in patients with microscopic infiltration in the parametrium and/or lymph node metastasis.
One hundred and thirty-two patients received postoperative radiation therapy following radical hysterectomy and pelvic lymphadenectomy for carcinoma of the uterine cervix Stage IB and IIA. In 43 patients with negative lymph node the 5- and 10-year survival rate was 85%. The other 89 patients with positive lymph node had 5- and 10-year survival rates of 60% and 51%, respectively. Multifactorial analysis of prognostic factors in the group of patients with lymph node metastasis disclosed pathology, microscopic infiltration in the parametrium and vascular space invasion as independent prognostic factors, that is, the 5-year survival rates were: 66% for squamous cell carcinomas versus, 25% for adenocarcinomas (p value: 0.001), 76% negative parametrium versus 39% positive parametrium (p value: 0.008), 68% no vascular space invasion versus 43% if invasion was observed (p value: 0.04). Sites of failure in 37 recurrences out of 89 patients with lymph node metastasis were pelvic alone 9, distant metastases alone 15, and combined pelvic plus distant metastasis in 12 patients. In one patient the site of failure was unknown. These data warrant more intensive local and systemic treatment, particularly in patients with poor prognostic factors. In the whole group, severe complications were observed in 11 patients.
