Clinicopathological Features and Prognosis of Small Cell Carcinoma of the Cervix

Small cell carcinoma of cervix (SCCC) is a rare disease with highly aggressive behaviour and is pathologically hard to diagnose.In this study, the clinicopathological features, diagnosis, treatment and prognosis of the condition were examined.Clinical records and follow-up data of 7 cases of SCCC were retrospectively studied.Our results showed that five non-recurrent cases initially presented irregular vaginal bleeding or increased apocenosis of varying degrees.Pathological examination revealed that the stroma was diffusely infiltrated with small monomorphous cells ranging from round to oval shape.Three cases were immunohistochemically confirmed.One case was accompanied with squamous cell cancer.Of the 7 cases, one case was classified as stage Ⅰb 1, two stageⅠ b2, one stage Ⅱ a, one stage Ⅱb , and one stage Ⅲ b.On the basis of their stages of condition, one subject with stage III b underwent chemotherapy, and one with stage Ib2 received extensive hysterectomy plus pelvic lymphadenectomy, while the other 5 cases were treated by extensive hysterectomy and pelvic lymphadenectomy in combination with pre-and/or post-operative adjuvant chemotherapy and radiotherapy.Of the 7 patients, 4 had relapse-free survival of 14, 14, 16 and 28 months respectively.It is concluded that SCCC is an aggressive tumor with propensity for early pelvis lymph node metastases.Early-stage patients should be treated by extensive hysterectomy and pelvic lymphadenectomy in combination with pre-and/or post-operative adjuvant chemotherapy and radiotherapy.
