Small cell carcinoma of the cervix: treatment and survival outcomes of 188 patients
ABSTRACT To determine the clinicopathologic factors associated with survival in neuroendocrine small cell cervical cancer patients.
Patients were identified from a review of literature with an additional 52 patients from four hospitals. Kaplan-Meier and Cox regression methods were used for analyses.
Of 188 patients, 135 had stages I-IIA, 45 stages IIB-IVA, and 8 stage IVB disease. A total of 55.3% underwent surgery, 16.0% had chemoradiation, 12.8% radiation, and 3.2% chemotherapy alone. The 5-year disease-specific survival in stage I-IIA, IIB-IVA, and IVB disease was 36.8%, 9.8%, and 0%, respectively (P < .001). Adjuvant chemotherapy or chemoradiation was associated with improved survival in patients with stages IIB-IVA disease compared with those who did not receive chemotherapy (17.8% vs 6.0%; P = .04). On multivariable analysis, early-stage disease and use of chemotherapy or chemoradiation were independent prognostic factors for improved survival.
Use of adjuvant chemotherapy or chemoradiation was associated with higher survival in small cell cervical cancer patients.

ABSTRACT: Both primary and secondary gynaecological neuroendocrine (NE) tumours are uncommon, and the literature is scarce concerning their imaging features. This article reviews the epidemiological, clinical and imaging features with pathological correlation of gynaecological NE tumours. The clinical features of gynaecological NE tumours are non-specific and depend on the organ of origin and on the extension and aggressiveness of the disease. The imaging approach to these tumours is similar to that for other histological types and the Revised International Federation of Gynecology and Obstetrics (FIGO) Staging System also applies to NE tumours. Neuroendocrine tumours were recently divided into two groups: poorly differentiated neuroendocrine carcinomas (NECs) and well-differentiated neuroendocrine tumours (NETs). NECs include small cell carcinoma and large cell neuroendocrine carcinoma, while NETs account for typical and atypical carcinoids. Cervical small cell carcinoma and ovarian carcinoid are the most common gynaecological NE tumours. The former typically behaves aggressively; the latter usually behaves in a benign fashion and tends to be confined to the organ. While dealing with ovarian carcinoids, extra-ovarian extension, bilaterality and multinodularity raise the suspicion of metastatic disease. NE tumours of the endometrium and other gynaecological locations are very rare. • Primary or secondary neurondocrine (NE) tumours of the female genital tract are rare. • Cervical small cell carcinoma and ovarian carcinoids are the most common gynaecological NE tumours. • Cervical small cell carcinomas usually behave aggressively. • Ovarian carcinoids tend to behave in a benign fashion. • The imaging approach to gynaecological NE tumours and other histological types is similar.01/2015; 6(1):43-52.

ABSTRACT: Extrapulmonary small cell carcinoma ( EPSCC extrapulmonary small cell carcinoma ) refers to small cell carcinoma arising outside of the lungs. EPSCC extrapulmonary small cell carcinoma is a rare aggressive neoplasm, representing a minority of all small cell carcinomas. Despite its uncommon occurrence, EPSCC extrapulmonary small cell carcinoma has been described in nearly every organ, most commonly in the gastrointestinal and genitourinary systems. As such, it is important for radiologists to be aware of the entity. Although imaging is neither sensitive nor specific for EPSCC extrapulmonary small cell carcinoma , it plays an important role by helping exclude metastases from a primary pulmonary tumor, establish tumor staging, and assess response to therapy. EPSCC extrapulmonary small cell carcinoma is diagnosed by demonstrating pathologic features of small cell carcinoma in an extrapulmonary site. There are two ways to stage EPSCC extrapulmonary small cell carcinoma . One method uses the Veterans Administration Lung Study Group system developed for small cell lung cancer that allocates patients into limited or extensive disease categories. The second approach is the American Joint Committee on Cancer tumor-node-metastasis system applied to other tumor subtypes arising from the same organ. Because of its rare and varied manifestations, the most effective treatment for EPSCC extrapulmonary small cell carcinoma has not been established. Current management recommendations are derived from retrospective studies and single-institution experiences or are extrapolated from small cell lung cancer data. Regardless of therapy, overall survival rates are poor, with 5-year survival rates around 13%. To help radiologists increase their familiarity with EPSCC extrapulmonary small cell carcinoma , this article provides (a) a background for EPSCC extrapulmonary small cell carcinoma based on the literature and (b) a pictorial review of EPSCC extrapulmonary small cell carcinoma in multiple organs, with radiologic-pathologic correlation.

ABSTRACT: The occurrence of cervical cancer during pregnancy is extremely rare, particularly small cell carcinoma. Small cell cervical carcinoma (SCCC) is a neuroendocrine tumor with a poor prognosis. This study presents the case of an 18-year-old female with stage IB2 SCCC complicated by pregnancy, who was treated with chemotherapy and radiotherapy. The patient was diagnosed shortly after giving birth, and is the youngest female case to be reported in the world. The patient was treated with cisplatin and etoposide chemotherapy and radiotherapy. Complete remission was achieved following neoadjuvant chemotherapy and radiotherapy, and the patient remains in clinical remission eight months following treatment. Cytological screening, colposcopy and if necessary, biopsy, and selective conization at 14-20 weeks should be considered in the patient evaluation.Oncology letters 01/2015; 9(1):91-95.
