Brain metastasis in papillary serous adenocarcinoma of the endometrium / Metástase cerebral do adenocarcinoma seroso-papilífero do endométrio

Abstract Background Most endometrial cancers (75%) are diagnosed in early stages (stages I and II), in which abnormal uterine bleeding is the most frequent clinical sign.When the diagnosis is performed in stage IV, the most common sites of metastasis are the lungs, liver and bones. Central nervous system (CNS)metastasis is a rare condition. The aim of this study is to describe a case of uterine papillary serous adenocarcinoma of the endometrium that progressed to brain and bone metastases. Case Report We present the case of a 56-year-old woman with abnormal uterine bleeding and endometrial thickened echo (1.8 cm). A hysteroscopy with biopsy was performed, which identified poor differentiated serous adenocarcinoma of the endometrium. A total abdominal hysterectomy, with pelvic and para-aortic lymphadenectomy, was performed. Analysis of the surgical specimen revealed a grade III uterine papillary serous adenocarcinoma. Adjuvant radio/chemotherapy (carboplatin and paclitaxel-six cycles) was indicated. Sixteen months after the surgery, the patient began to complain of headaches. Brain magnetic resonance imaging demonstrated an expansile mass in the right parietal lobe, suggesting a secondary hematogenous implant subsequently confirmed by biopsy. She underwent surgery for treatment of brain metastasis, followed by radiotherapy. She died 12 months after the brain metastasis diagnosis due to disease progression. Conclusion Uterine papillary serous adenocarcinoma of the endometrium has a low propensity to metastasize to the brain. To the best of our knowledge, this is the fifth documented case of uterine papillary serous adenocarcinoma of the endometrium with metastasis to the CNS.

Resumo Fundamentos A maioria dos cânceres de endométrio (75%) é diagnosticada em estágios iniciais (estágios I e II), nos quais o sangramento uterino anormal é o sinalclínico mais frequente. Quando o diagnóstico é realizado no estágio IV, os locais mais comuns de metástase são os pulmões, o fígado e os ossos. A metástase para o sistema nervoso central (SNC) é uma condição rara. O objetivo deste estudo é descrever um caso de adenocarcinoma seroso-papilífero do endométrio que progrediu para metástases cerebral e óssea. Relato de Caso Apresentamos o caso de uma mulher de 56 anos com sangramento uterino anormal e eco endometrial espessado (1,8 cm). Foi realizada histeroscopia com biópsia que identificou adenocarcinoma seroso-papilífero pouco diferenciado do endométrio. Uma histerectomia abdominal total, com linfadenectomia pélvica e para-aórtica, foi realizada. A análise da peça cirúrgica revelou adenocarcinoma seroso-papilífero do endométrio grau III. Radioterapia adjuvante/quimioterapia (carboplatina e paclitaxel- seis ciclos) foi indicada.Dezesseismeses após a cirurgia, a paciente começou a se queixar de dores de cabeça. A ressonância magnética cerebral demonstrou uma massa expansiva no lobo parietal direito, sugerindo um implante hematogênico secundário posteriormente confirmado por biópsia. A paciente foi submetida a cirurgia para tratamento de metástase cerebral, seguida de radioterapia. A paciente morreu 12 meses após o diagnóstico de metástase cerebral devido à progressão da doença. Conclusão O adenocarcinoma seroso-papilífero do endométrio tem uma baixa propensão a metastizar para o cérebro. Até onde sabemos, este é o quinto caso documentado de adenocacinoma seroso-papilífero do endométrio com metástase para o SNC.

Discussion about the approach to diagnosis and treatment of the hepatoid adenocarcinoma of the stomach / 国际外科学杂志

Hepatoid adenocarcinoma of the stomach (HAS) is defined as a special type of gastric cancer characterized by low incidence rates and high degree of malignance with an extremely poor prognosis.As it is characterized by morphological similarities to general alimentary cannal symptoms with unclear etiology and pathogenesis,diagnostic errors can always be made.The alpha-fetoprotein (AFP) and carcino-embryonic antigen (CEA) are helpful with diagnosis.However,histopathological examination is the gold standard for diagnosing HAS.So far,radical operation,adjuvant chemotherapy,interventional therapy with immune-biological treatment are the main approaches for HAS treatment.

A retrospective study of surgical treatment for stage Ⅰ pure bronchioloalveolar carcinoma comparison with adenocarcinoma of the lung / 中华胸心血管外科杂志

Objective To analyse the difference between stage Ⅰ pure bronchioloalveolar carcinoma (BAC) and stage Ⅰ adenocarcinoma of the lung among operative cases.Methods We use the Lobectomy Cases Registration and Statistics System database (2006-2011) to compare the epidemiology,clinical presentation,image characteristics,surgical outcomes,recurrence and overall survival between BAC and adenocarcinoma groups.All the patients received lobectomy procedure in the department of thoracic surgery of Peking University People' s Hospital.Results Excluding those cases with both BAC and adenocarcinoma aspects,337 patients were enrolled.Thirty-nine patients were stage Ⅰ pure BAC and 298 patients were stage Ⅰadenocarcinoma.BAC has its proper clinical spectrum,occurring more frequently in women (69.2％ vs.52.0％,P =0.042)and in younger patients (57.4 vs.61.8,P =0.014).BAC also seems to be less dependent on tobacco exposure (12.8％ vs.29.9％,P =0.026).The percentage of ground-glass opacity (GGO) in CT scan of BAC patients was much more than that registered in adenocarcinoma patients (35.9％ vs.9.7％,P ＜0.001).And the tumor size of BAC group was smaller than that of the adenocarcinoma group (1.4 cm vs.2.3 cm,P ＜0.001).The operation method,time,blood loss and complications were similar between the two groups.Kaplan-Meier survival curves showed that both 3-year disease-free survival (DFS) and overall survival (OS) were significantly higher in patients affected by BAC (100％ vs.76.1％,P =0.030 and 100％ vs.86.1％,P =0.041).Conclusion BAC presents specificity in its epidemical,clinical,radiological and evolutionary aspects.Stage Ⅰ pure BAC patients have better prognosis following video-assisted thoracoscopic lobectomy and system lymph node dissection than the similar stage adenocarcinoma patients.

Clinical Analysis of Patients with Primary Intestinal Tumous:A Report of 68 Cases / 中国医师杂志

Objective To explore the diagnosis and surgical treatment of primary intestinal tumors, and improve the level of treatment. Methods Retrospective analysis of the clinical was made on the 68 cases of primary small intestinal tumors confirmed by pathological examination in our department in recent 20 years. HZ Results 34.8%(21/68) was benign tumors in 68 cases, and 69.1%(47/68) was malignancies. The common clinical prevsentations were abdominal pain (69.1%,47/68). gastrointestinal he morrhage (41.1%,28/68) and abdomen mass (13.2%,9/68). The preoperative misdiagnosis rate was 70.5%(48/68) .All the 68 cases performed operation, and no death. The 1 ,2 and 5 years survival rates of malignant tumors were 65.8%,42.1% and 29.3% respectively. Conclusions The clinical presertation of primary small intestinal tumor is non-spectific and the misdiagnosis rate is high. Kinds of diagnosis examinations should be done for the cases whose diagnosis are uncertain, and laboratory examinations should be considered if it is need. The main choice of treatment is surgery and the chemotherapy is necessary for malignant tumors also.

The Influence of Superantigen Staphylococcal Enterotoxin B on the Proliferation of TILs from Rectum Adenocacinoma / 中国医师杂志

Objective To study the effects of staphylococcal enterotoxin B(SEB) on the proliferation of tumor infiltrating lymphocytes(TILs) from rectum adenocacinoma.Methods The TILs from patients with rectum adenocacinoma were stimulated with SEB and interleukin 2(IL-2) respectively,and then the proliferation of TILs,the secretion of IL-2 and tumor necrosis factor-?(TNF-?) were determined.Results SEB presented profound stimulating effect on the TILs from rectum adenocarcinoma both the proliferation of TILs and the secretion of cytokines.Compared with the IL-2,SEB stimulated TILs more quickly,and SEB acted more effectively in the early stage but weakly in the late stage.Conclution SEB was an effective TIL stimulator.

Clinical analysis of patients with primary intestinal tumours: a report of 72 cases / 中国普通外科杂志

Objective To explore the diagnosis and surgical treatment of primary intestinal tumors (PIT), to improve the diagnosis and treatment. Methods Retrospectively analysis was made on the clinical data of 72 patients with PITs admitted to our hospital from 1988 to 2002. Results Out of the 72 cases, 20.8% (15/72) had benign tumors, while the remaining 79.2% (57/72) were malignancies. The former were mostly adenoma and liomyoma, each accounting for 40.0% (6/15) of the benign tumors. Adenocarcinoma was the most common type of malignancy (36.8%,21/57), following lymphadenoma (30.0%, 17/57). The main diagnostic methods were X-ray,B-ultrasonic,CT, endoscopy and superior mesenteric arteriography.The misdingnosis rate was 62.5% before operation in this series.Of the 72 cases underwent operation,25 underwent emergent operation (33.3%, 25/72), because acute intestinal obstruction, digestive tract bleeding or perforation,acute appendicitis were diagnosed before the operation.In this series,there was no operative death;the 1,3,5 year survial rates of malignance were 62.5%,47.5%,25.0%,respectively. Conclusions PIT is not easily diagnosed before operation, and the misdiagnosis rate and emergent operation rate are high. Superior mesenteric arteriography,radiologic contrast examination of the small bowel are the important means of diagnosis in jejunum or ileum tumour, and the best way to diagnosis duodenal neoplasms is hypotonic duodenography and endoscopy. Once the diagnosis of PIT is made, the best choice of treatment is operation.
