Abstract

Purpose : To evaluate the clinical findings, prognosis and treatment strategy of patients with neuroendocrine carcinoma of cervix. Materials and Methods: Thirteen patients with neuroendocrine carcinoma of cervix were included in this study, as confirmed histologically and immunohistochemically at the Dongsan Medical Center, Keimyung University, between May 1944 and October 2001. The mean age of patients was 56 years with a range of 32 to 78 years of age. According to the FIGO staging system, there were 5 patients with stage IB carcinoma, 5 patients with IIA, and 3 patients with stage IIB. Four patients underwent radical hysterectomy with pelvic lymphadenectomy, 3 of these patients also received postoperative radiotherapy, and one patient underwent extrafascial hysterectomy after radiotherapy. Primary radiotherapy was done in 9 patients, and 3 were irradiated postoperatively. Nine patients received chemotherapy, 7 received neoadjuvant and 2 received concurrent chemoradiotherapy. The radical purpose of radiotherapy consisted of external irradiation to the whole pelvis (4,500 $\~$5,400 cGy) and intracavitary irradiation (3,000 $\~$ 3,500 cGy). Results : The mean follow up duration was 36 months with a range of 3 to 104 months. The overall 5-year survival rate was 61.5$\%$ and the 5-year survival rates for stage IB, IIA, IIB were 60.0$\%$, 60.0$\%$, and 66.7$\%$ respectively (p=0.99). Eight patients are still alive without disease, and all of the 5 patients with recurrence are dead due to distant metastasis. Conclusion : Neuroendocrine carcinoma of cervix is highly aggressive, with early lymphatic dissemination and a high rate of distant recurrence. Therefore, an aggressive therapeutic strategy Is required to obtain pelvic and distant disease control. Multimodal therapy should be considered at the time of Initial diagnosis.

목적 :. 자궁경부의 신경내분비암은 비교적 드문 질환으로 본원에서 광학현미경 및 면역조직화학적 진단을 받고, 치료받은 환자를 대상으로 임상적 특징, 예후 및 치료방침에 대해 알아보고자 한다 대상 및 방법: 1994년 5월부터 2001년 10월까지 본원에서 조직학적으로 자궁경부 신경내분비암으로 진단받은 환자 13예를 대상으로 하였다. 환자의 평균 연령은 56세(32$\~$78세)이며, 병기분포는 IB 5명, IIA 5명, IIB 3명이었다. 수술을 시행한 환자는 5명으로 이 중 3명은 수술 후 방사선치료를 추가하였다. 근치적 방사선치료를 시행한 환자는 9명이며, 이 중 1명은 방사선치료 후 근막외 자궁적축술을 시행하였고, 선행 혹은 동시항암화학요법을 시행한 환자는 9명이었다. 방사선치료는 병기에 따라서 전골반부 4,500$\~$5,400 cGy까지 외부조사 후, 강내조사를 주 2회, A point에 1회당 500 cGy로 3,000$\~$3,500 cGy를 조사하였다. 결과 : 추적관찰기간은 3개월에서 104개월로 평균 36개월이었다. 5년 생존율은 61.5$\%$이었으며, 병기별 5년 생존율은 병기 IB 60.0$\%$, IA 60.0$\%$, IB 66.7$\%$로 통계적으로 유의한 차이가 없었다(p=0.99). 전체 13명 중 5명(38.5$\%$)이 사망하였으며, 이 중 4명에서 골반부위 및 복부대동맥 주위 임파절 전이가 확인되었고, 이들 모두 원격장기 전이로 사망하였다. 사망자의 평균생존기간은 5개월이며, 임파절 전이 유무에 따라서 통계적으로도 유의한 차이(p=0.0001)를 관찰할 수 있었다. 나머지 8명은 무병생존중이다. 결론 : 자긍경부의 신경내분비암은 초기병기일지라도 임파절전이와 원격전이가 많고 병의 진행이 급속히 이루어지는 양상을 보이므로 국소치료인 수술이나 방사선치료와 함께 전신적인 복합항암화학요법을 병행하는 것이 좋을 것으로 생각되며 적절한 병합치료가 환자의 생존율을 향상시킬 것으로 생각된다.
