Abstract
Small-cell neuroendocrine cervical carcinoma (SCNCC) is a rare yet aggressive gynecological malignancy associated with dismal clinical outcomes. Its rarity has led to a limited number of retrospective studies and an absence of prospective research, posing significant challenges for evidence-based treatment approaches. As a result, most gynecologic oncology centers have limited experience with this tumor, emphasizing the urgent need for a comprehensive review and summary. This article systematically reviews the pathogenesis, immunohistochemical and molecular characteristics, prognostic factors, and clinical management of gynecologic SCNCC. We specifically focused on reviewing the distinct genomic characteristics of SCNCC identified via next-generation sequencing technologies, including loss of heterozygosity (LOH), somatic mutations, structural variations (SVs), and microRNA alterations. The identification of these actionable genomic events offers promise for discovering new molecular targets for drug development and enhancing therapeutic outcomes. Additionally, we delve deeper into key clinical challenges, such as determining the optimal treatment modality between chemoradiation and surgery for International Federation of Gynecology and Obstetrics (FIGO) stage I phase patients within a precision stratification framework, as well as the role of targeted therapy within the homologous recombination (HR) pathway, immune checkpoint inhibitors (ICIs), and prophylactic cranial irradiation (PCI) in the management of SCNCC. Finally, we anticipate the utilization of multiple SCNCC models, including cancer tissue-originated spheroid (CTOS) lines and patient-derived xenografts (PDXs), to decipher driver events and develop individualized therapeutic strategies for clinical application.

Abstract
Small cell carcinoma of the uterine cervix (SCCUC) is rare and its biologic behavior is aggressive. To analyze prognostic factors and determine optimal therapy in patients with International Federation of Gynecology and Obstetrics (FIGO) stage IB1-IIA SCCUC, we retrospectively reviewed 96 patients (14 patients treated in our center and 82 patients identified by a search on PubMed) treated with radical surgery (SU), surgery plus adjuvant chemotherapy (SU+Chemo), or surgery plus adjuvant chemotherapy and radiotherapy (SU+Chemo+RT) between 1990 and 2010. Of the 96 patients, 11 patients were treated with SU, 33 with SU+Chemo, and 52 with SU+Chemo+RT. The 5-year survival rate for the 96 patients was 45%. A total of 6% (2/32) of patients had local recurrence, 75% (24/32) had distant metastases, and 19% (6/32) had both. The 5-year survival rate in stage IB1 and IB2-IIA disease was 58 and 34%, respectively (P=0.049). For patients with and without lymph node metastases (LNM), survival was 33 and 60%, respectively (P=0.045). Patients with inner 1/3 stromal invasion had a better survival than those with deep stromal invasion (DSI) (100 vs. 34%, P=0.003). Survival was not significantly different in patients treated with the above three modalities, albeit treatment selection was related to LNM (P=0.000) and DSI (P=0.027). Thus, FIGO stage, LNM and DSI are significant predictors of survival. Adjuvant therapy after SU has not improved survival compared with surgery alone. Thus, newer multimodality therapy should be evaluated.

Abstract
OBJECTIVE Neuroendocrine tumors of the gynecologic tract are rare, and pose a significant clinical challenge because of the tumor heterogeneity and lack of standardized guidelines for treatment. This manuscript summarizes the available literature concerning these tumors in an effort to provide the clinician a framework from which to guide patient management. METHODS MEDLINE was searched for all research articles published in English between January 1, 1966 and March 1, 2011 in which the studied population included women diagnosed with neuroendocrine tumors of the gynecologic tract. Although preference was given to prospective studies, studies were not limited by design or by numbers of subjects given the limited availability of reports. RESULTS Most, but not all, neuroendocrine tumors of the gynecologic tract have an aggressive clinical course and those of the cervix histologically and clinically share similarities with small cell lung cancer. Cumulative data supports a multi-modality therapeutic strategy. A proposed management algorithm for neuroendocrine carcinomas of the cervix is outlined. For less frequent disease sites including the adnexa, uterus, vagina and vulva, as well as well differentiated carcinoid tumors, surgical resection is appropriate in selected cases. Etoposide/platinum based chemotherapy is used for neuroendocrine carcinomas but not for well differentiated carcinoid tumors. Well differentiated carcinoid and atypical carcinoid tumors should be managed similar to gastroenteropancreatic NETs (GEP-NETs). CONCLUSIONS Most neuroendocrine tumors of the gynecologic tract require a multi-modality therapeutic approach, determined by extent of disease and primary organ of involvement. Pathologic diagnosis is critical to guide therapy.

Abstract
OBJECTIVE To determine the clinicopathologic factors associated with survival in neuroendocrine small cell cervical cancer patients. STUDY DESIGN 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. RESULTS 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. CONCLUSION Use of adjuvant chemotherapy or chemoradiation was associated with higher survival in small cell cervical cancer patients.

Abstract
We report 5 polypoid high-grade neuroendocrine carcinomas of the uterus, 2 small cell carcinomas of the endometrium, and 3 large cell neuroendocrine carcinomas, 2 from the cervix and 1 from the endometrium. The 2 small cell carcinomas of the endometrium arose from and were confined to endometrial polyps, one of which also showed foci of endometrioid adenocarcinoma. The myometrium was free of tumor, despite extensive sampling. The 3 large cell neuroendocrine carcinomas, 2 from the cervix and 1 from the endometrium, were polypoid but did not originate in polyps. Two of these tumors infiltrated myometrium, and one did not. The age of the 5 patients ranged from 25 to 66 years (mean age, 43 years). Four patients presented with vaginal bleeding. One pregnant woman had the largest polypoid tumor discovered during a routine gynecologic examination. Tumor sizes ranged from 2.7 to 10 cm. All 5 patients were treated by radical hysterectomy and 4 received adjuvant chemotherapy. Only 2 patient had pelvic lymph node metastasis. All patients are alive and disease-free from 9 months to 7 years after treatment (mean survival, 47 months). All 5 tumors labeled with chromogranin and synaptophysin and 4 with CD56. Two small cell carcinomas and 2 large cell neuroendocrine carcinomas accumulated p53 protein. Two small cell carcinomas and 2 large cell neuroendocrine carcinomas expressed p16. Our findings suggest that stage of disease and a polypoid gross feature are the best predictors for outcome in small cell carcinomas and large cell neuroendocrine carcinomas of the uterus.

Abstract
Small cell carcinoma of the uterine cervix accounts for 1-3% of all cervix cancers. It is an aggressive disease with a poor prognosis. To date, no effective treatment protocol has been determined. Surgery, radiotherapy, and chemotherapy have been used either alone or in combination. Recent data suggests that survival in patients with early staged small cell carcinoma of the cervix is better with surgery combined with chemo-radiotherapy. Here, we presented two patients with stage IB1 small cell carcinoma of the uterine cervix. For both patients, definitive surgery was performed with pelvic and para-aortic lymphadenectomy. Subsequently, they were treated with pelvic external radiotherapy and high-dose-rate intracavitary brachytherapy with concurrent cisplatin based chemotherapy. They were alive with no evidence of disease at 91 and 65 months, respectively.

Abstract
Neuroendocrine tumor of the uterine cervix is a rare and aggressive malignancy. Despite controversial, multimodal treatment methods, prognosis and treatment outcomes are worst in advanced stages. We report an early-stage case treated with the multimodal approach. The nomenclature proposed for this tumor type in 1997 by the College of American Pathologists still has some points of discussion. As in our case some of the tumors cannot be defined exactly into small or large cell types, and this causes confusion at least for nomenclature purposes. A 'mixed' type for this tumor may be appropriate.

Abstract
INTRODUCTION Large cell neuroendocrine carcinoma is a rare aggressive cervical neoplasm, considerably rarer than the well-recognized small cell neuroendocrine carcinoma of the cervix. Cervical large cell neuroendocrine carcinomas are distinctive cervical carcinomas that are frequently misdiagnosed and have an unfavorable outcome, similar to that of small cell carcinoma. CASE REPORT We report a 45-year-old woman with large cell neuroendocrine uterine cervical carcinoma.

Abstract
BACKGROUND Small cell carcinomas (small-CCs) of the uterine cervix are rare and highly malignant neoplasms. Patients tend to develop distant metastasis early and thus are potential candidates for systemic therapy. We reviewed the experience with small-CCs of the uterus and vagina at two Austrian University hospitals. MATERIAL AND METHODS Ten patients (median age, 50 years; range, 18-92) with small-CC of the cervix (n=7), uterine corpus (n=2), and the vagina (n=1) were treated at the two centers between 1988 and 1998. Eight patients underwent radical surgery, 7 of whom also received chemotherapy. Two additional patients underwent primary radiotherapy. RESULTS All Pap smears were suspicious for cervical malignancy. The median survival was 12 months (range, 6-86) and overall 5-year survival was 10%. Five of 8 surgically treated patients had lymph node involvement (62%). Of the 7 patients with small-CC of the cervix only one, who had FIGO stage IIB disease and positive pelvic nodes, survived long-term (86 months) with no evidence of disease. She had received six courses of dose-intensive platinum chemotherapy after radical surgery. All three patients with small-CC of the uterine corpus or vagina developed recurrence within the first year after diagnosis. Of the 7 patients who received chemotherapy, 5 developed progressive or recurrent disease in the paraaortic region (n=2), peritoneum (n=1), liver (n=1), or pelvis (n=1). CONCLUSION These results confirm the particularly unfavorable prognosis of patients with small-CC of the genital tract. The optimal treatment for these patients most probably including concurrent chemo-radiotherapy remains to be defined.

Abstract
OBJECTIVES To analyze the sites of relapse and overall survival in women with neuroendocrine marker-positive small cell carcinoma of the cervix. METHODS The records of all women who had their initial treatment for cervical cancer at The University of Texas M.D. Anderson Cancer Center between 1980 and 2000 were reviewed. Fifty-one patients had stages I-III cancers that were originally described as "small cell" or "neuroendocrine." Histological material was available for reexamination in 45 cases; of these, 21 were found to have small cell neuroendocrine carcinoma (SCNEC) as indicated by positive staining for chromogranin, synaptophysin, or CD56. Local treatment consisted of a radical hysterectomy in six patients and radiation therapy in 15. Thirteen patients received chemotherapy as part of their initial treatment. The median follow-up for surviving patients was 83 months (range, 25-209 months). RESULTS Fourteen (66%) of the 21 patients had a relapse. The median time to first relapse from the initiation of treatment was 8.4 months (range, 3.6-28 months). Most patients developed hematogenous distant metastases before their death. Only 2 of 15 patients who were treated with radiation therapy had a recurrence within the radiation fields. However, five patients had a recurrence above the radiation fields in the paraaortic lymph nodes, and two patients had a recurrence distal to the pelvic fields in the vagina. No patient had brain metastases as the sole site of first recurrence. However, two patients developed brain metastases concurrently with lung metastases. The overall survival rate was 29% at 5 years; none of the patients who had disease more extensive than stage IB1 or clinical evidence of lymph node metastases survived their disease. CONCLUSIONS Patients with small cell neuroendocrine cervical cancer have a poor prognosis. Their course is frequently characterized by the development of widespread hematogenous metastases; locoregional recurrence outside irradiated fields is also frequent. Brain metastases were seen only in patients who also had lung metastases, suggesting that prophylactic cranial irradiation would be of little benefit.

Abstract
PURPOSE To identify prognostic factors and treatment toxicity in a series of operable stages IB and II cervical carcinomas. PATIENTS AND METHODS Between May 1972 and January 1994, 414 patients (pts) with cervical carcinoma staged according to the 1995 FIGO staging system underwent radical hysterectomy with (n = 380) or without (n = 34) bilateral pelvic lymph node dissection. Lateral ovarian transposition to preserve ovarian function was performed on 12 pts. The methods of radiation therapy (RT) were not randomised and depended on the usual practices of the surgical teams. Group I: 168 pts received postoperative RT (64 pts received vaginal brachytherapy alone [mean total dose (MD): 50 Gy], 93 pts had external beam pelvis RT (EBPRT) [MD: 45 Gy over 5 weeks] followed by vaginal brachytherapy [MD: 20 Gy], and 11 pts had EBPRT alone [MD: 50 Gy over 6 weeks]. Group II: 246 pts received preoperative utero-vaginal brachytherapy [MD: 65 Gy], and 32 of theses 246 pts also received postoperative EBPRT [MD: 45 Gy over 5 weeks] delivered to the parametric and the pelvic lymph nodes with a midline pelvic shield. The mean follow-up was 106 months. RESULTS The 10-year disease-free survival (DFS) rate was 80%. From 75 recurrences, 35 were isolated locoregional. Multivariate analysis showed that independent factors decreasing the probability of DFS were: both exo and endocervical tumour site (p = 0.047), lymph-vascular space invasion (p = 0.041), age < or = 51 yr (p = 0.013), 1995 FIGO staging system (stage IB1 vs stage IIA, p = 0.004, stage IB1 vs stage IB2, p = 0.0009, and stage IB1 vs stage IIB with 1/3 proximal parametrical infiltration, p = 0.00002), and histological pelvic involved lymph nodes (p = 0.00009). Methods of adjuvant RT did not influence the probability of DFS (group I vs group II, p = 0.10). The postoperative complication rate was 10.2% in group I and 8.9% in group II (p = 0.7) but the postoperative urethral complication rate necessitating surgical intervention with reimplantation was lower in group I than in group II (0.6% vs 2.3%, respectively, p = 0.03). The 10-year rate for grade 3 and 4 late radiation complications according to the LENT-SOMA scoring system was 10.4%. EPRT significantly increased the 10-year rate for grade 3 and 4 late radiation complications (yes vs no: 22% vs 7%, respectively, p = 0.0002). CONCLUSION In our series, the methods of adjuvant RT (primary surgery vs preoperative uterovaginal brachytherapy) do not seem to influence the prognosis of the stage IB, IIA, and IIB (with 1/3 proximal parametrical involvement only) cervical carcinomas. The postoperative EPRT applied according to histopathological risk factors after surgical treatment increases the risk of late radiation complications.

Abstract
OBJECTIVE The objective of this study was to determine whether clinicopathologic findings or the immunohistochemical presence of molecular markers are predictive of clinical outcome in patients with small cell carcinoma of the cervix (SCCC). METHODS A retrospective review of cases of carcinoma of the cervix was conducted to identify SCCC. From 1978 to 1999, 16 patients were identified at our institution with the diagnosis of SCCC. Microscopic sections of paraffin-embedded tissue specimens were evaluated for confirmation of diagnosis. Specimens were immunohistochemically stained with antibodies to three neuroendocrine markers: neuron-specific enolase, chromagranin (CGR), and synaptophysin. Specimens were also stained for protein expression of p53, erbB2, proliferating cell nuclear antigen, and c-myc. The relationship between molecular markers and clinical outcome was determined. RESULTS All 16 cases met the histologic criteria for SCCC. Fourteen of 16 tumors (88%) stained positive for neuroendocrine differentiation. Eleven of 16 patients (69%) died from disease with a median survival of 19 months; there were 3 long-term survivors (greater than 5 years). CGR was positive in 8 (50%) specimens and was found to be highly predictive of death (P = 0.001). Complete loss of p53 protein was seen in 8 patients, 7 of whom died with a median survival of 20 months. CONCLUSION Immunohistochemistry can be helpful in confirming difficult cases of SCCC. Further studies are necessary to define molecular markers that may be predictive of outcome in patients with SCCC.

Abstract
BACKGROUND Large cell neuroendocrine cervical carcinoma is a rare malignancy. These tumors appear to mimic the aggressive behavior of small cell neuroendocrine tumors. Metastasis and recurrent disease are common. Due to the low incidence of these tumors, optimal therapy has not been delineated. CASES Two patients presented with large cell neuroendocrine cervical carcinoma, stage IB1 and IIA, at our institution from 1997 to 1999. We describe the clinical course for these two patients and review the relevant literature for the management of large cell cervical carcinoma. CONCLUSION Unlike squamous cell carcinoma, early-stage large cell neuroendocrine tumors of the cervix are aggressive. Disease recurrences are frequent and distant metastasis is common. Multimodal therapy should be considered at the time of initial diagnosis.

Abstract
OBJECTIVE The aim of this study was to analyze diagnostic criteria, response to chemotherapy, rate and site of relapse, and overall survival (OS) in neuroendocrine cervical carcinoma. METHODS Twenty patients were included. Stage was Ia(2) in 1 case, Ib(1) in 4, Ib(2) in 4, II in 5, IIIb in 2, IVa in 2, and IVb in 2. Patients with stage Ib(2) or greater received neoadjuvant chemotherapy (NCH). Eighteen patients were operated on. Immunohistochemistry was performed on the surgical specimens. Statistical analysis included the Kaplan-Meier method and the chi(2) and log-rank tests. RESULTS The response to NCH was <50% in 2/13 cases (15.3%), >50% in 9/13 (69.4%), and complete in 2/13 (15.3%). Cytokeratin was positive in 17/18 cases, neuron-specific enolase in 15/18, chromogranin in 9/18, and synaptophysin in 8/18. Tumor was pure in 12 cases. Two cases had simultaneous ovarian carcinoma. Positive nodes were observed in 9/20 pts (45%). Tumors <4 cm had no recurrences. Pure tumors >4 cm had distant relapses (6/11). Mixed tumors >4 cm had 2/6 pelvic and 3/6 lung metastases. OS was 39%. When the initial tumor volume was <4 cm OS was 76%, and it was 18% for tumors >4 cm (P < 0.05). OS was 58% when the residual tumor after NCH was <2 cm and 21% when it was >2 cm (P < 0.05). When the tumor was pure OS was 54% and 19% when it was mixed (P < 0.05). OS was 72% among pts with negative nodes and 11% for those with positive nodes (P < 0.01). CONCLUSIONS (1) Stage IV was frequent (20%); (2) Response to NCH was high; (3) The pattern of relapse differs for mixed tumors; (4) For tumors <4 cm outcome is similar to that of squamous carcinoma.

Abstract
OBJECTIVE Patients with early-stage neuroendocrine cervical carcinoma (NECC) have a high mortality rate despite aggressive therapy. The rarity of this tumor precludes initiation of a randomized, prospective trial. We reviewed our experience in early stage disease and performed a meta-analysis of the literature to identify prognostic factors and determine optimal multimodality therapy. METHODS Eleven women with International Federation of Gynecology and Obstetrics (FIGO) early stage (IB--IIA) NECC were treated with surgery and chemotherapy at our institutions between 1978 and 1998. Administration of radiation therapy was recorded, but not required for inclusion in this study. A gynecologic pathologist reviewed all histopathologic sections. Medical records were retrospectively reviewed and clinical data obtained. Twenty-three early-stage NECC patients who were similarly treated during the study interval were identified by a Medline search of the English literature and included in the analysis. The Kaplan--Meier method and log-rank test were used for survival analysis. RESULTS The overall 2-year survival rate for the 34 patients was 38%. The median age was 37 years (range, 20--75 years). Median cervical tumor diameter was 3.2 cm (range 0.5--11.0 cm). Lymphovascular space invasion was present in 21 (78%) of 27 patients (7 unknown). Fifteen (52%) of twenty-nine had lymph node metastases (5 unknown). Fifteen patients received postoperative platinum/etoposide (PE), seven received vincristine/adriamycin/cyclophosphamide (VAC), two received alternating cycles of VAC and PE, and ten received other chemotherapy regimens. Twenty women were treated with radiation therapy. The presence of lymph node metastases was a poor prognostic factor (P < 0.001). PE and VAC chemotherapy was associated with increased survival (P < 0.01). CONCLUSION NECC is a highly lethal variant of cervical cancer. The presence of lymph node metastases is the most important prognostic variable. Postoperative VAC or PE appears most likely to improve chances for survival.

Abstract
Neuroendocrine small cell carcinoma of the uterine cervix (NESCCC) is an entity with very aggressive behaviour. The optimal initial therapeutic approach to this rare disease has not yet been clearly defined. We reviewed our experience of this disease over the past 10 years with regard to chemosensitivity. Since 1988, ten patients (mean age 33 years; range 24-47) have been diagnosed with NESCCC and treated in our institutions. Disease stage at presentation was IA (one), IB (five, two with lymph node involvement), IIB (one), IIIB (one), and IV (two). One patient had metastatic disease at presentation; three developed metastases during initial treatment. Eight patients underwent surgery and eight received radiation therapy. Six patients received pre- or postoperative cisplatinumvepeside (PE) combination chemotherapy, either alone or concurrently with radiation therapy. PE alone as primary chemotherapy led to disease stabilization in the two patients so treated; concurrent PE and radiation therapy resulted in a pathological complete response in one patient. Eight patients relapsed within 16 months and died of their disease within 29 months from the initial diagnosis. Two patients are alive with no evidence of disease at 13 and 53 months. Our series confirms the previously described very poor prognosis of NESCCC, despite initial aggressive multidisciplinary treatment. It may be that the introduction of chemotherapy, especially combined primary chemoradiotherapy, might allow patients to do a little better, although at the moment there is no good evidence one way or the other.

Abstract
Four main clinicopathologic features of neuroendocrine tumors (NETs) of the cervix may be stressed: primary diagnosis at an advanced stage, early nodal metastasis even for low disease, early failure of appropriate local treatment (surgery and/or radiation therapy) and aggressive clinical treatment. Five patients with NET of the uterine cervix (small cell carcinoma type) are reported (one stage I, two stages II, one stage III and one stage IV). One patient was treated by surgery combined with radiation therapy, one by surgery combined with chemotherapy and one by surgery with radiation therapy and chemotherapy. Two patients received radiation therapy alone. Three early stage patients are alive with no evidence of disease 8, 26 and 41 months after diagnosis. The two patients with advanced stage died of disease, 3 and 12 months respectively, after diagnosis. Combination chemotherapy (cisplatin and etoposide) is warranted in disseminated NETs. Neoadjuvant or adjuvant chemotherapy should be combined with radiation therapy and surgery even in early stages.

Abstract
Neuroendocrine tumors of the cervix are rare and are often under- or misdiagnosed. Because these tumors are very aggressive, early diagnosis and subsequent treatment are warranted. We describe a 46-yr-old woman with carcinoid syndrome caused by an atypical carcinoid of the uterine cervix. At age 44, she had dysplasia on Pap smear and underwent total abdominal hysterectomy with the diagnosis of adenocarcinoma. Fourteen months postoperatively, she developed the carcinoid syndrome and was found to have numerous liver metastases. Histological and immunohistochemical investigations of biopsy specimens from the patient's liver lesions and original cervical lesion ("adenocarcinoma") suggested that this woman had a primary atypical carcinoid of the uterine cervix with metastases to the liver. Treatment with octreotide and alkylating agents decreased the episodes of flushing and diarrhea within 8 weeks. If an adenocarcinoma of the uterine cervix is diagnosed, atypical carcinoid should be in the differential diagnosis. Symptoms of the carcinoid syndrome should be pursued and, if present, a urinary 5-hydroxyindolacetic acid level should be obtained. Timely diagnosis of a neuroendocrine tumor of the cervix may improve survival.

Abstract
Small cell neuroendocrine carcinoma of the cervix is very rare and is usually associated with dismal prognosis if treated by conventional surgery and radiotherapy even in early stage disease. This tumor is characterized by early lymphatic and hematogenous spread. Only one successfully treated case of small cell neuroendocrine carcinoma of the cervix with dissemination to the pelvic nodes had been reported before in the literature. We are reporting a case of small cell neuroendocrine carcinoma of the cervix with multiple pelvic nodal metastases including the common iliac nodes, which had been successfully treated with a multimodal approach including radical hysterectomy, pelvic/para-aortic lymphadenectomy, and postoperative chemotherapy using cisplatin-etoposide combinations and pelvic irradiation.

Abstract
BACKGROUND Small cell carcinoma of the uterine cervix is an uncommon tumor associated with high mortality even among patients with early stage disease. The role of adjuvant chemotherapy after surgery has been suggested by regimens used for small cell lung carcinoma. During the years 1980-1997, 19 cases in which various adjuvant chemotherapies were given after hysterectomy were reported in the literature published in English. METHODS Adjuvant chemotherapy was administered consecutively to 23 patients with Stage Ib-II small cell cervical carcinoma who had been primarily treated with radical hysterectomy and had adequate bone marrow, renal, and hepatic functions. A combination of vincristine, doxorubicin, and cyclophosphamide alternating with cisplatin and etoposide (VAC/PE) was administered to 14 patients during the years 1988-1996 according to a prospective study protocol. A combination of cisplatin, vinblastine, and bleomycin (PVB) was administered to 8 patients, and another regimen was administered to 1 patient during the years 1984-1988. Prognostic factors were evaluated by analyzing both the data on these 23 patients and the pooled data on the cases retrieved from the literature and our own files. RESULTS Ten of the 14 patients who received VAC/PE had no evidence of disease during a median follow-up of 41 months, whereas 3 of the 9 who received PVB or another regimen survived. Of the 10 patients who died of their disease, all died of distant metastasis within 10 months after recurrence. Meta-analysis of the pooled data showed that 68% of patients who received regimens containing VAC or PE survived, whereas 33% of patients who received regimens not containing VAC/PE survived (P = 0.0078, log rank test). Seventy percent of patients with no lymph node metastasis at hysterectomy and 35% with lymph node metastasis survived (P = 0.05). All patients who died of disease had extrapelvic metastasis. CONCLUSIONS Chemotherapies containing VAC or PE are favorable regimens for patients with early stage small cell cervical carcinoma after radical hysterectomy.

Abstract
BACKGROUND This study was performed to identify pathologic and clinical features that best predict disease free survival of patients with early stage small cell carcinoma of the cervix treated by radical hysterectomy. METHODS Three hundreds and seventy patients with cervical carcinoma were analyzed retrospectively to define those variable that best predict disease free survival (DFS). Variables included age, weight, race, marital status, economic status, tumor size, depth of invasion (DI), lymph-vascular space involvement (LVSI), cell type, tumor grade, lymph node metastasis (LNM), and total number of lymph nodes removed. Patients with lymph node metastasis, parametrial involvement, and positive or close surgical margins were offered postoperative radiation. RESULTS Twelve patients were found to have small cell carcinoma (3.2%). One patient had microinvasive carcinoma of the cervix (MIC) as defined by the Society of Gynecologic Oncologists with a depth of invasion of 3 mm or less and no lymph-vascular space invasion, and has been reported previously. A detailed analysis of the other patients with nonsmall cell carcinoma is presented separately. Five patients achieved a DFS of at least 5 years, whereas 7 patients died with disease. Excluding the patient with MIC, the 5-year DFS rate was 36.4%. CONCLUSIONS Relative to other cell types, small cell carcinomas of the cervix is an aggressive neoplasm with a higher rate of LVSI and LNM despite smaller DI and tumor size. These data suggest that multimodality therapy, combining radical surgery and radiation with cytotoxic chemotherapy, may provide these patients with the best chance for cure.

Abstract
AIMS To examine neuroendocrine differentiation, as shown by chromogranin A (CGA) expression, in cervical carcinomas. METHODS Sixty seven cervical carcinomas were studied and were classified as adenocarcinomas, adenosquamous carcinomas or squamous cell carcinomas based on the assessment of haematoxylin and eosin staining and stains for mucin. Where features of glandular differentiation were identified, sections were also stained for evidence of intestinal type mucin. CGA immunostaining was done and the results were graded on a three point scale: 0, + (1-5% of cells positive) and ++ (> 5% of cells positive). These findings were then analysed with respect to lymph node status, tumour differentiation and clinical outcome. RESULTS There were 32 adenocarcinomas, 18 adenosquamous carcinomas and 17 squamous cell carcinomas. Positive staining was seen in 14 (20.9%) cases, of which four were strongly positive. All but one case were either adenocarcinomas or adenosquamous carcinomas. There was a trend for CGA positivity to be related to intestinal differentiation but this failed to reach statistical significance. No correlation could be demonstrated between CGA staining and lymph node status, tumour differentiation and clinical outcome. CONCLUSIONS Neuroendocrine differentiation is common in cervical carcinomas where there is evidence of glandular differentiation. Whilst the numbers in this study are relatively small, the presence of neuroendocrine cells in otherwise typical carcinomas does not seem to have any association with clinical behaviour.

Abstract
Extrapulmonary small cell cancer is rare, but it occurs in a wide variety of sites, where it has a behaviour quite different from the tumours normally found at those sites. Prognosis is generally poor, but combined modality treatment with combination chemotherapy can often achieve useful palliation and, occasionally, long term remission and cure.

Abstract
We report a case of a 33-year-old woman who presented with the rapid development of multiple dermal and subcutaneous nodules on the chest, back, abdomen, axilla, neck, and scalp. These nodules were firm, tender, and non-ulcerated and measured from 0.2 to 1.2 cm in diameter. A punch biopsy of one of the subcutaneous nodules in the scalp showed a poorly differentiated carcinoma in the reticular dermis with light microscopic, immunohistochemical, and ultrastructural features supporting neuroendocrine differentiation. The past medical history was significant for a recent total abdominal hysterectomy for carcinoma of the cervix at another hospital, originally characterized as a poorly differentiated adenocarcinoma of the cervix and lower uterine segment. Review of the microscopic slides of the uterine neoplasm revealed features suggesting a more appropriate classification as a primary neuroendocrine carcinoma; this was subsequently confirmed by immunophenotyping and ultrastructural evaluation. This is the first reported case of a uterine neuroendocrine carcinoma metastasizing exclusively to the skin. It further illustrates the important contribution of dermatopathology to the understanding of a systemic pathologic process.

Abstract
Substantial evidence for involvement of the APUD system in the normal reproductive tract is limited to the prostate gland and uterine cervix. Most supportive data simply documents the presence of neuro-endocrine cells in these tissues. A biological product(s) or role(s) remains to be discovered, but appears likely in the prostate. Tumors possessing cells with APUD characteristics have been described in many reproductive tissues including the prostate, cervix, endometrium, ovary, and testes. These tumors are generally aggressive in behavior, and optimum therapy needs to be determined.

Abstract
Between July 1986 and February 1991, 10 patients with small cell carcinoma of the cervix were prospectively treated with combination chemotherapy using cisplatin (50 mg/m2) and doxorubicin (50 mg/m2) on Day 1 and etoposide (75 mg/m2) on Days 1-3. All patients underwent an extensive pretreatment metastatic survey and had histologic confirmation of small cell carcinoma prior to entry in the study. Seven patients had stage Ib, 1 stage IIa, and 2 stage IIb. Nine patients received chemotherapy at primary presentation and 1 was treated for recurrent disease. In 6 cases, chemotherapy was given and then followed by radiation therapy. Three patients received chemotherapy following radical hysterectomy and 1 was treated for persistent disease after radiation therapy. Patients received a median of four courses of chemotherapy (range 2-6). Neutropenia was the dose-limiting toxicity with 9 of 10 patients requiring a dose reduction. There was no instance of neutropenic sepsis or other major toxicity. Seven patients had measurable disease at the start of therapy. Three of these patients had a complete clinical response, 1 had a partial response, 2 had stable disease, and 1 had progressive disease (response rate = 57%). The median survival was 28 months. At the time of this report, 4 of 6 patients with stage Ib cancers given primary treatment on this regimen remained free of disease (with 28 months the median follow-up). Our pilot study indicates that this chemotherapy regimen has activity in small cell carcinoma of the cervix and should be further evaluated as an adjuvant to surgery or radiation in patients with early stage disease.
