Abstract
Extrapulmonary small-cell carcinoma (SCC) is a rare neoplasm that shares certain features with its pulmonary counterpart and occurs predominantly in the gastrointestinal tract (GIT). It is a high-grade and poorly differentiated neuroendocrine tumor, usually diagnosed in advanced stages, with a poor prognosis and few therapeutic options in that setting. This is a case report of a 77-year-old Spanish male patient with localized SCC of the colon, who presented a pathological complete response in the surgical specimen after neoadjuvant chemotherapy with cisplatin and etoposide. To date, 5 years after surgery, the patient remains without evidence of tumor recurrence. As clinical guidelines for the management of this entity are lacking, and therefore its management has not been standardized, an attempt to summarize the current evidence in the literature was made.

Abstract
Extrapulmonary small cell carcinomas (EPSCC) are rare malignancies with poor patient prognoses. We present the case of a 63-year-old male who underwent surgical resection of a poorly differentiated small cell carcinoma, likely from a small intestinal primary tumor that metastasized to the cerebellopontine angle (CPA). A 63-year-old male presented with mild left facial paralysis, hearing loss, and balance instability. MRI revealed a 15 mm mass in the left CPA involving the internal auditory canal consistent with a vestibular schwannoma. Preoperative MRI eight weeks later demonstrated marked enlargement to 35 mm. The patient underwent a suboccipital craniectomy and the mass was grossly different visually and in consistency from a standard vestibular schwannoma. The final pathology revealed a poorly differentiated small cell carcinoma. Postoperative PET scan identified avid uptake in the small intestine suggestive of either a small intestinal primary tumor or additional metastatic disease. The patient underwent whole brain radiation therapy and chemotherapy and at last follow-up demonstrated improvement in his symptoms. Surgical resection and radiotherapy are potential treatment options to improve survival in patients diagnosed with NET brain metastases. We present the first documented case of skull base metastasis of a poorly differentiated small cell carcinoma involving the CPA.

Abstract
Hepatocellular carcinoma (HCC) is one of the most deadly cancers worldwide. It is well known that the activation of PI3K/AKT/mTOR and the Ras/MAPK signaling pathway plays a critical role in cellular metabolism, growth and proliferation, and its inhibitors have been used as therapeutic drugs for hepatocellular carcinoma. Cetuximab, a chimerical monoclonal EGFR IgG1 antibody, can block the binding of EGF or other ligands to EGFR and thus inhibit ligands-induced receptor phosphorylation. In the present study, we found that rapamycin could enhance the antiproliferation effect of cetuximab in both HepG2 cells and Huh-7 cells and arrest the cell cycle. Cetuximab in combination with rapamycin had synergistic effects on inhibiting the phosphrylation of proteins in PI3K/AKT/mTOR and Ras/MAPK signaling pathway. Combination of cetuximab with rapamycin treatment significantly suppressed the HCC development in HepG2 cells-xenografted mice and improved the survival. Cetuximab and rapamycin inhibited the growth of HCC both in vitro and in vivo. These results suggest that the combination therapy using the inhibitors for both EGFR and PI3K/AKT/mTOR signaling pathways may be a novel therapeutic approach for HCC.

Abstract
BACKGROUND We investigated clinicopathologic features in patients with esophageal small cell carcinoma (SCEC), and its proliferative activity and angiogenesis. METHODS Ten patients with SCEC from 335 esophageal carcinoma patients were analyzed clinicopathologically. For analyses of cell proliferation, apoptosis, and angiogenesis of SCEC, Ki-67 immunostaining, the TUNEL method, and CD31 and CD68 immunostaining were used. RESULTS Esophagectomy was performed in nine patients, while one with extensive SCEC was treated by repeated chemotherapy and radiotherapy. Four patients received chemotherapy both before and after surgery, one only before surgery, and four only after surgery. Cisplatin and etoposide were given to five patients, while irinotecan and cisplatin were given to three. Five survived more than 18 months, and two more than 36 months. One of these two had limited SCEC treated by surgery and chemotherapy, whereas the other had extended SCEC treated by repeated chemotherapy and radiotherapy. The microvessel count and the Ki-67 labeling index of SCEC were higher than those of squamous cell carcinoma (P = 0.0033 and P = 0.0005, respectively). Between SCEC with and without preoperative chemotherapy, the Ki-67 labeling index was lower (P = 0.027) and the apoptotic index was higher in the treated SCEC (P = 0.014). Between SCEC patients who survived more or less than 18 months, the microvessel count was lower in those who survived more than 18 months (P = 0.049). CONCLUSIONS Esophagectomy may be indicated for limited SCEC combined with chemotherapy. SCEC has high proliferative activity and rich neovascularization, and its proliferative activity may be suppressed by chemotherapy.

Abstract
Small cell undifferentiated carcinoma (SmCC) of the gastrointestinal tract (GIT) is a rare and highly aggressive malignancy. To date, fewer than 1,000 cases have been reported, with an estimated prevalence of 0.1% to 1% of all gastrointestinal (GI) tumors. Data on the disease are scarce due to its rarity and the fact that most authors have focused on one site within the GIT. In light of the limited data and its perceived similarity to SmCC of the lung, the disease has usually been treated as the latter. Nevertheless, recent clinicopathologic and molecular data imply several differences between the two entities, questioning the extent to which extrapolations from one to the other can be made. We review the available data on GI SmCC with emphasis on outlining its clinicopathologic features and the recommended treatment approach.

Abstract
OBJETIVO: Identificar alterações pulmonares em pacientes com neoplasia esofágica. Comparar os dados obtidos, além de mostrar sua relação com o tabagismo. MATERIAIS E MÉTODOS: Estudo transversal tipo série de casos. Foram analisados prontuários e exames de imagem (tomografias computadorizadas e radiografias) de 55 pacientes com câncer de esôfago, diagnosticados entre 1998 e 2001, no Hospital de Base de São José do Rio Preto. Comparou-se a freqüência dos tumores encontrados e outras alterações pulmonares em dois grupos de pacientes: tabagistas e não tabagistas. RESULTADOS: Quarenta e seis (83%) pacientes apresentaram carcinomas espinocelulares, sete (13%) adenocarcinomas, um (2%) carcinoma de pequenas células e um (2%) linfoma não-Hodgkin. Quarenta e oito (87%) pacientes eram tabagistas e sete (13%) eram não tabagistas. Entre os tabagistas, 89% possuíam carcinoma espinocelular, 9% adenocarcinoma e 2% carcinoma de pequenas células. Entre os não tabagistas, 57% apresentaram adenocarcinoma, 28% carcinoma espinocelular e 15% linfoma não-Hodgkin. Houve metástases em quatro tabagistas e em dois não tabagistas. A prevalência das alterações pulmonares (infiltrado intersticial, enfisema e pneumonia) foi maior nos tabagistas (73%) do que nos não tabagistas (27%) (p = 0,03). CONCLUSÃO: Este fato reforça a importância da avaliação pulmonar nos pacientes com neoplasia esofágica.

Abstract
PurposeTo improve our understanding of the entity of small-cell carcinoma (SmCC) of the gastrointestinal (GI) tract.MethodsA MEDLINE search was done, using the terms “small cell carcinoma” or “oat cell carcinoma” combined with “gastrointestinal” or with any of the GI sites, for the period 1970 to 2003. The 138 eligible reports identified in this way were reviewed for clinical data.ResultsTo date, approximately 544 cases of GI SmCC have been reported. The disease represents 0.1% to 1% of all GI malignancies, with the esophagus being the most common primary site. A majority of patients present with overt distant metastases. Systemic symptoms are common; ectopic hormonal secretion may occur. By light microscopy, GI SmCCs are essentially indistinguishable from primary pulmonary SmCC. The presence of non-SmCC components is common. Data from molecular analysis of the disease has identified some similarities to pulmonary SmCC. Chemotherapy represents the main treatment option, with modest impact on survival. In locoregional disease, the literature suggests that treatment be initiated using chemoradiotherapy and then, if metastatic disease is still excluded, surgical resection be considered. The disease is highly aggressive, and survival is in the range of several weeks for untreated patients and of 6 to 12 months for those receiving therapy.ConclusionSmCC of the GI tract is a rare and lethal disease. Although there are many similarities to pulmonary SmCC, some differences between the two entities are suggested. While chemotherapy can achieve significant palliation, surgery may have a potential impact on long-term survival of patients with locoregional disease.

Abstract
A 63-year-old man presented to our hospital with persistent dysphagia. Radiologic and endoscopic examination disclosed a 2.0-cm exophytic tumor in the middle third of the esophagus. An endscopically obtained biopsy specimen was found to represent undifferentiated small cell carcinoma. Computed tomography of the chest, abdomen, and cervical region was performed, as were gallium and bone scintigraphy. Metastasis to an adjacent lymph node was detected, without metastasis to distant organs. After neoadjuvant chemotherapy with carboplatin (CBDCA) (400 mg/m2) and etoposide (VP-16) (100 mg/m2), endoscopy and barium-swallow esophagography showed regression. Thoracic esophagectomy then was performed with mediastinal, abdominal and cervical lymph node dissection. The resected tumor was polypoid, measuring 0.5 x 0.5 cm. The lesion consisted mainly of small anaplastic cells, but included a small focus of squamous cell carcinoma. The patient has survived for more than 7 months with no further treatment and no evidence of recurrent disease.
