ABSTRACT BACKGROUND
The purpose of this study was to evaluate the clinical and pathologic factors associated with survival in patients with neuroendocrine (NE) cervical carcinoma.METHODS
All patients with NE cervical carcinoma diagnosed between 1979–2001 were identified from tumor registry databases at two hospitals. Data were collected from hospital charts, office records, and tumor registry files. The impact of clinical and pathologic risk factors on the survival of patients with small cell NE carcinoma of the cervix was evaluated using Kaplan–Meier life table analyses and log-rank tests. The independent prognostic factors found to be predictive of survival in univariate analysis were evaluated using Cox regression. All tests were two-tailed with P values < 0.05 considered significant.RESULTSThirty-four patients (median age, 42 years) were diagnosed with neuroendocrine cervical carcinoma, which included 21 with International Federation of Gynecology and Obstetrics (FIGO) Stage I disease, 6 with FIGO Stage II disease, 5 with FIGO Stage III disease, and 2 with FIGO Stage IV disease. Seventeen patients underwent a radical and 6 patients underwent a simple hysterectomy. Fourteen women received adjuvant therapy with pelvic radiation and/or cisplatin-based chemotherapy. Ten women received primary radiotherapy with (n = 5) or without (n = 4) chemotherapy and the remaining patient refused therapy. Women with early-stage (Stage I-IIA) disease had median survival rates of 31 months compared with 10 months in the advanced-stage (Stage IIB-IVB) group (P = 0.002). In univariate analysis, advanced stage (P = 0.002), tumor size >2 cm (P = 0.02), margin involvement (P = 0.016), pure versus a mixed histologic pattern (P = 0.04), margin status (P = 0.016), and smoking (P = 0.04) were considered poor prognostic factors. In multivariate analysis, smoking for early-stage patients and stage of disease in the overall population remained as independent prognostic factors of survival.CONCLUSIONS
Smoking and advanced stage are reported to be poor prognostic factors for survival in patients with NE small cell carcinoma of the cervix. Only those with early lesions amenable to extirpation are cured. The role of primary or postoperative radiation with or without chemotherapy is unclear and yields uniformly poor results, particularly in patients with advanced lesions. Clinical trials are needed.

    ABSTRACT: Small cell cervical carcinoma (SCCC) is a rare, aggressive tumor with a poor prognosis. However, information in relation to its treatment is scarce due to the limited numbers of patients. The aim of this study was to establish whether platinum-based combination chemotherapy may by beneficial in this patient population. We carried out a multicenter, retrospective study comprising of 72 Chinese patients with SCCC. The patients were treated between 1995 and 2010 at Sun Yat-sen Memorial Hospital or the Cancer Center of Sun Yat-Sen University, and at the First Affiliated Hospital of Shantou University Medical College, China. Of the 72 patients, 46/72 (63.9%) had Federation of Gynecology and Obstetrics (FIGO) stage Ia-Ib2 and 26/72 (36.1%) had stage IIa-IV disease. Surgery was performed in 63/72 (87.5%) patients, 61/72 (84.7%) patients received chemoradiotherapy and 35/72 (48.6%) received radiotherapy. The 3-year overall survival (OS) and disease-free survival (DFS) rates were as follows: Ia (100%, 100%); Ib1 (62%, 57%); Ib2 (53%, 48%); IIa (36%, 23%); IIb (29%, 21%); IIIb (50%, 50%); and IV (0%, 0%), respectively. The estimated 3-year OS and DFS rates in patients who received platinum-based combination chemotherapy (etoposide + cisplatin [EP], or paclitaxel + cisplatin [TP]) as part of their adjuvant treatment were 64.8% and 63.0%, respectively, compared to 25.2% and 22.0% in those who did not (P = 0.0003; P = 0.0003). Univariate analysis showed that platinum-based combination chemotherapy was associated with improved survival compared to other chemotherapy techniques or no chemotherapy (OS: HR = 0.227; 95% CI, 0.099-0.524; P = 0.001; DFS: HR = 0.210; 95% CI, 0.087-0.506; P = 0.001). Multivariate analysis identified FIGO stage, lymphatic metastasis and platinum-based combination chemotherapy as independent prognostic factors for improved survival in patients with SCCC. Platinum-based combination chemotherapy (with EP or TP) can improve the 3-year survival outcomes in patients with SCCC. Therefore, it should be considered an important component in a future standardized treatment strategy for SCCC.

    ABSTRACT: Small cell carcinoma of the uterine cervix (SMCC) is extremely rare, and an aggressive disease that proliferates rapidly. It was often reported that the diagnostic accuracy of cytologic smears in diagnosing SMCC was low. This is a report of the Severance Hospital experience with the patients suffering from SMCC. Twenty-seven patients with small cell carcinoma of the uterine cervix were diagnosed and treated at the Severance Hospital from November 1991 to January 2010. The data were analyzed retrospectively, based on the available charts and pathology reports. Various fields, such as chief complaints and symptoms present at first clinic visit, age, International Federation of Obstetrics and Gynecology (FIGO) clinical stage, treatment modality, the 5-year overall survival rate, and recurrence rate were investigated. Among the 27 patients diagnosed with small cell carcinoma of the uterine cervix, 18 of them (66.7%) presented with symptoms, including vaginal bleeding, at the first clinic visit, and the remaining 9 patients (33.3%) showed abnormal Pap smear screening in the process of their routine health check-up. The median age of the patients was 54 years (range, 24 to 77 years). FIGO stage IIB was the most common stage (11 of 27 patients). The 5-year overall survival rate of 21 patients, who could be followed up, was 57.2%. Six patients showed recurrence after remission, and the mean disease free interval of them was 9.2 months (range, 6 to 11 months). Abnormal Pap smear screening results of 9 patients was investigated, and the diagnostic accuracy of the cytologic findings was 22.2%. Our study was consistent with the concept that Pap smear screening might not be helpful in early diagnosis of SMCC considering its low diagnostic accuracy. Further large-scale multicenter prospective studies are definitely needed in order to produce abundant information about optimal therapy and diagnosis.
