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.

    • "One of the causes of small cell carcinoma of the uterine cervix is HPV infection, and in particular, HPV type 18 is closely associated [8]. Clinically, small cell carcinoma of the uterine cervix has similar characteristics with small cell lung carcinoma [6]. About 60% of SmCC is diagnosed in International Federation of Gynecology and Obstetrics (FIGO) stages I and II. "

    ABSTRACT: Small cell carcinoma of the uterine cervix is rare. It is estimated that 10% of patients with small-cell lung cancer have syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and hyponatremia has been reported to be significantly associated with a poor prognosis. A proportion of small cell carcinoma of the uterine cervix exhibit neuroendocrine characteristics as revealed by immunohistochemistry, However, cases presenting typical symptoms due to SIADH are extremely rare. This report of the SIADH of the uterine cervix is a rare case in the small cell carcinoma of the cervix presenting with tumor-associated paraneoplastic syndrome.

    • "SmCC progresses rapidly to hematogenous and lymphogenous metastases, and has a poor prognosis [2] [3] [4] [5] [6] [7] [8] [9] [10]. Reported 5-year survival rates are: stages IA2–IB1, 55% to 85%; stages IB2–II, 25% to 30%; and stages III–IV, 0% to 16% [3] [4] [5] [6] [7]. Even in stage I, compared to other histologic types, the prognosis is significantly worse [3] [4]. "

    ABSTRACT: Objectives: This is a multicenter, collaborative study to accumulate cases of small cell carcinoma of the uterine cervix (SmCC), to clarify its clinical and clinicopathologic features and prognosis, and to obtain findings to establish future individualized treatment. Methods: At medical centers participating in the Kansai Clinical Oncology Group/Intergroup, patients diagnosed with SmCC between 1997 and 2007 were enrolled. Clinicopathologic features and prognosis were retrospectively evaluated in patients with SmCC diagnosed at a central pathologic review. Results: A total of 71 patients were registered at 25 medical centers in Japan. Of these, 52 patients (73%) were diagnosed with SmCC based on a pathological review. These 52 patients diagnosed with SmCC were analyzed. The median follow-up period was 57 months. The 4-year progression-free survival (PFS) was: IB1, 59%; IB2, 68%; IIB, 13%; and IIIB, 17%. The 4-year overall survival (OS) was: IB1, 63%; IB2, 67%; IIB, 30%; IIIB, 29%; and IVB, 25%. For postoperative adjuvant therapy, postoperative chemotherapy (a platinum drug in all cases) was compared to non-chemotherapy. The 4-year PFS was 65% and 14%, and the 4-year OS was 65% and 29%. PFS was significantly better (p=0.002), and the OS tended to be better (p=0.073) in the group with postoperative chemotherapy. Conclusion: Even in patients with early stage SmCC, the prognosis is poor. However, in early stage patients, by adding postoperative chemotherapy, the prognosis may improve. Currently, various treatment protocols are used at each medical center, but in the future, a standardized treatment protocol for SmCC will hopefully be established.

    • "The most common site of SCC is lung. In 1930, extrapulmonary SCC was first described by Duguid and Kennedy.1 Since then, cases of SCC have been reported in almost all sites of the body, including the gastrointestinal tract (GIT),2 head and neck,3 urinary tract,4 and genital system.5 "

    ABSTRACT: Small cell carcinoma of the gastrointestinal tract is a rare and aggressive neuroendocrine tumor. This study aims to analyze the clinical characteristics and potential prognostic factors for patients with limited stage small cell carcinoma of the gastrointestinal tract. The records of 27 patients with limited stage small cell carcinoma of the gastrointestinal tract, who all received surgery with lymphadenectomy, were retrieved and analyzed retrospectively. The median age of patients was 60 years old (range 38-79). The primary locations of tumor were the esophagus (74.1%) and stomach (14.8%). The rate of preoperative accurate diagnosis (16.7%) was low for small cell carcinoma of the esophagus and stomach. 40.7% of all the patients had regional lymph node metastases. Five patients underwent surgery alone, and the other 22 were treated with surgery + postoperative chemotherapy. All patients had disease progression or recurrence. The overall median survival time was 10 months and the 1-year survival rate was 37.0%. Patients who received postoperative chemotherapy had a median survival time of 12 months, which was superior to the 5-month survival of for those who only had surgery (P<0.0001). TNM stage (P=0.02) and postoperative chemotherapy (P<0.0001) were considered as two prognostic factors in uni-variate analysis. Postoperative chemotherapy was a significant independent prognostic factor in multivariate analysis (P=0.01). The prognosis for patients with limited stage small cell carcinoma of the gastrointestinal tract remains dismal, however, postoperative chemotherapy may have the potential to improve the outcome for these patients.
