Abstract
OBJECTIVES
To investigate clinicopathologic findings of patients with small cell carcinoma of uterine cervix, and to evaluate the recurrence pattern and prognosis of patients with small cell carcinoma of the uterine cervix. Methods: From Jan. 1990, to Dec. 1997, 23 patients with small cell carcinoma of the uterine cervix were registered and followed-up at Korea Cancer Center Hospital. Clinical characteristics, survival of these patients were studied retrospectively. RESULTS: Among the 23 cases of small cell carcinoma of uterine cervix, 17 cases(74%) were of the neuroendocrine type (NE group), and 6 cases(26.0%) of the squamous cell type (SCC group). The median age, FIGO stage, and treatment modality were not significant difference between two groups. Pelvic lymph node metastases were found 53% in NE group, and 33% in SCC group, but there were not significant difference between two groups(p>0.05). Three patients showed distant metastases in NE group(bone 18%, bladder 9%), but there was no distant metastasis in SCC group. The 3 year survival rate was 50.0% in SCC group and 32.1% in NE group, but there were not statistical significance(p>0.05). Six patients showed recurrence after treatment (4/17 cases in NE group, 2/6 cases in SCC group). Recurrence sites were liver (3/6, 50%), and lung (2/6, 33%), brain (2/6, 33%), retroperitoneum (1/6, 17%), and axillae lymph node (1/6, 17%). CONCLUSION: This study showed neuroendocrine small cell carcinoma may have more aggressive than squamous small cell carcinoma, but there were not significant difference in prognosis between the two groups. Because of limitation of number of patients, further large scaled multicenter studies are needed.
