RESUMO
We report the case of a 55-year-old-male with a large cell metastatic pancreatic neuroendocrine carcinoma treated for 14 months with lanreotide autogel having a stable disease (SD) and not responding to chemotherapy. The somatostatin analogues (SSA) were introduced after an episode of diarrhea and controlled the disease. Progression-free survival (PFS) as determined by Computerized Tomography (CT) scans was obtained for 14 months. After more than a year, the patient's health state deteriorated along with progressive disease. The capecitabine-temozolomide regimen was challenged, but after three cycles, a rapid clinical decline was noted. CONCLUSION: This unexpected event (diarrhea) in the course of the disease could represent the beginning of carcinoid syndrome. While the lanreotide autogel helped the episode of diarrhea pass, it also helped gain control over the disease itself.
RESUMO
CONTEXT: Pancreatic neuroendocrine tumours (PanNETs) are rare pancreatic neoplasms. PanNETs can be treated by multimodal approach including surgery, locoregional and systemic therapy. OBJECTIVE: The aim of the present study is to evaluate predictive factors of overall survival in patients with PanNETs surgically treated at a single center. SUBJECTS AND METHODS: The study group consisted of 120 patients with PanNETs who had undergone surgery at the Center of Digestive Diseases and Liver Transplantation of Fundeni Clinical Institute, Bucharest, Romania. Surgical resection of the primary tumor was performed in 110 patients. RESULTS: Tumor size > 2 cm (p=0.048) (90% CI) lymph node involvement (p=0.048), ENET grade (p<0.001), distant metastases (p<0.001), Ki 67 index (<2%, 2-5%, 5-10%, 10-20%, >20%) (p<0.001) were identified as significant prognostic factors for OS on univariate analysis. Using multivariate Cox proportional regression model we found that distant metastases and Ki 67 index were independent risk factors for the survival outcome. CONCLUSIONS: Surgery with curative intent should be considered in all cases if clinically appropriate and technically feasible. High grade (Ki67 index ≥10%) tumours were associated with a 2- fold increase in risk of death as compared to those with a Ki67 <10%.
RESUMO
We present the case of a 76 year old female patient admitted in the Department of Cardiology for physical asthenia, profuse sweating and dyspnea with orthopnea for about one month. Clinical and paraclinical assessments performed at admission confirmed the diagnosis of cardiac tamponade. Surgical intervention was performed and 400 mL of clear effusion were drained. Post-operative evolution was marked by recurrence of symptoms, requiring after 3 weeks a new drainage of 600 mL of clear effusion, and biopsy of the pericardium was performed. Pathological exam described serous pericarditis with chronic inflammatory infiltrate, xanthogranulomatous reaction intricated in the pericardium and mesothelial hyperplasia. The patient was subsequently transferred to the Department of Internal Medicine for further investigations. Physical examination showed a patient with altered general status, pallor, vesicular murmur absent in both bases, presenting cutaneous hyperpigmentation at the level of the right hemi-abdomen and hip with posterior extension, and a peripheral indurated erythematous plaque. The patient presented nodular masses of 3 cm in the right latero-cervical and bilateral axillary regions, non-adherent to the superficial structures, as well as adenopathic blocks in both inguinal regions. CT scan of the thorax and abdomen showed moderate bilateral pleuresia, minimal pericardial effusion (15 mm) and multiple adenopathies on both sides of the diaphragm. Skin biopsy was performed, as well as bone marrow aspirate and excision of a right axillary lymph node. Pathological exams and immunohistochemistry tests confirmed the diagnosis of Plasma Cells Castleman disease.

AIM: The impact of venous resection (VR) in pancreatico-dudenectomy (PD) for pancreatic adenocarcinoma (PDAC) is controversial. The aim of the study is to comparatively assess the postoperative outcomes after PD with and without VR for PDAC and to identify predictors of morbidity and survival in the subgroup of PD with VR. METHODS: The data of 51 PD with VR were compared with those of 183 PD without VR. Binary logistic regression and Cox survival analyses were performed. RESULTS: Both the operative time and estimated blood loss was significantly higher in the VR group (P<0.001). A trend towards an increased 90-day mortality (9.8% vs. 5.5%) and severe morbidity (20% vs. 13%) was observed when a VR was performed (P ≥0.264). The median overall survival time after the PD with and without VR was 13 months and 17 months, respectively (P=0.845). The absence of histological tumor invasion of the VR was found as the only independent predictor for a better survival (HR=0.359; 95% CI 0.161-0.803; P=0.013). CONCLUSION: A PD with VR can be safely incorporated in a pancreatic surgeon armamentarium. However, the trend towards increased mortality and severe morbidity rates should be expected, along with higher operative time and blood loss, compared with PD without VR. Associated VR does not appear to significantly impair the prognosis after PD for PDAC; however, histological tumor invasion of the VR has a negative impact on the survival.
RESUMO
AIM: The aim of our study was to investigate the gene and serum protein expression profiles of IL-8 in colon cancer and associated hepatic metastasis and to correlate these results with clinicopathologic variables of the patients. MATERIALS AND METHODS: IL-8 was evaluated by qPCR and ELISA in a total number of 62 colon cancer patients (n=42 by qPCR and n=20 by ELISA) in normal and tumoral tissue specimens and serum samples respectively. Additionally synchronous metastasis from 5 of these patients were also collected at the time of surgery and analyzed by qPCR. RESULTS: IL-8 was up regulated in all analyzed tumoral samples compared with normal tissue (P-value = 0.01) and higher expressed in metastatic tissues compared with tumoral tissues (P -value= 0.03). The median expression of IL-8 in patients over 60 years old was found to be higher compared with the median expression of IL8 in patients less than 60 years old (3.89 compared with 14.69, P -value= 0.005). According to tumor grading, we found that IL-8 in tumors with well differentiated adenocarcinoma have a median mRNA expression of 9.78 compared with a median mRNA IL8 expression of 26.63 in moderate or poor differentiated adenocarcinoma. Levels of IL-8 determined in serum were statistically significant correlated with preoperative carcinoembryonic antigen level (P -value= 0.003, R=0.57) and with distant metastasis (P-value =0.008). Serum level of IL-8 increased proportionally along with TNM tumor stage and was found to be statistically significant correlated with C-reactive protein (P -value, R=0.64). Colon cancer patients had higher IL-8 levels as determined by ELISA (median value= 29.64 pg/ml) compared with healthy controls (median value= 4.86 pg/ml). DISCUSSIONS: Our results provide additional support for the role of inflammation in colon cancer and indicate that IL-8 could be further validated in association with other already used markers for prognostic and diagnostic of evolutional disease in colon cancer patients.

We present the case of a 70-year-old woman, with a history of radiation-treated and surgically- resected cervical cancer, who was admitted to our clinic for intermittent sub occlusive symptoms. CT scan revealed a liver nodule and intestinal obstruction. The patient underwent surgery for excision of suspected liver metastasis and resolution of intestinal obstruction.Intraoperatively an ileal tumour was found to be the cause of the obstruction. Anatomo-pathological findings were consistent with an ileal metastasis from the cervical cancer.The liver nodule was only an area of focal steatosis.

The lipoma of the colon is a benign and rare tumor. Most lipomas are asymptomatic, their discovery being fortuitous. The diagnosis is ussualy easy by colonoscopy associated with biopsies. The abdominal CT scan also has its role in the diagnostic process and in the assesment of the tumoral extension.The treatment depends essentially on the clinical picture, on the size and location of the lipoma and involves endoscopic or surgical excision. We present the case of a 56 years old woman in which a random colonoscopic and than tomographic diagnosis of a sigmoidian lipoma was made 2 years ago when the patient presented with different symptoms, the submucosal lipoma being small sized at the time; the surgical treatment(sigmoidectomy including the tumor) was currently indicated by the sub-occlusive syndrome and haematochezia, due to the intraluminal proliferation of the tumor.

AIM: Given the context that rectal tumours respond to a certain degree to radiotherapy, a necessity arises for estimating a tumour's capacity to react to radiation from the very moment of diagnostic biopsy. MATERIAL AND METHODS: We have histologically and immunohistochemically analysed tissues coming from 52 patients with rectal adenocarcinomas. RESULTS: Of the studied parameters, the ones presenting significant variation under radiotherapy in terms of statistics(p 0.05) were: colloid type (p=0.001), EGFR in the tumour(p=0.00045), EGFR in the normal epithelium (p=0.0017),VEGF in the tumour (p=0.0132) and VEGF in the tumour stroma (p=0.030). CONCLUSIONS: Our study follows the same trends as the medical literature we have consulted regarding the variation of EGFR and VEGF with radiotherapy, and the distinct note of our study relies in the observation that normal stroma in case of rectal tumors also reacts to radiotherapy, sometimes more aggressively than the tumor itself, especially in which concerns the nerve and muscle fibers.

BACKGROUND & AIMS: Liver transplantation (LT) is a promising treatment for patients with liver cirrhosis associated with hepatocellular carcinoma (HCC). The aim of our study was to evaluate our experience regarding the clinical and pathological staging of HCC in patients who underwent LT, as well as recurrence free and overall survival. METHODS: From January 2006 to December 2011, 38 patients with diagnosis of HCC, underwent LT in our Center. Demographic, clinical, imaging and pathologic information were recorded. A Cox proportional hazards survival analysis was performed in order to identify significant predictors of tumor recurrence and patient's death after LT. RESULTS: Eighteen patients (47.4%) in our study group were within Milan criteria. The mean follow-up was 22 months and the recurrence rate of HCC after LT was 13.2%. The 1, 3- year recurrence free survival rates were 85%, 74.3% respectively. The 1 and 3-year overall survival rates were 83.5% and 63.6% respectively. No significant predictor for HCC recurrence was identified in our study group by survival analysis, taking into account 13 different variables. As independent predictors of patient'ss death after LT for HCC however, the presence of diabetes mellitus (p=0.001), presence of more than 3 HCC nodules (p=0.03) and tumor recurrence after LT (p=0.03) were identified by multivariate Cox proportional hazards survival analysis. CONCLUSION: In our cohort HCC recurrence rate after LT was 13.2%. Diabetes mellitus, presence of more than 3 HCC nodules and HCC recurrence were significant predictors of poor overall survival after LT.

Squamous cell carcinoma is a very rare type of urachal malignancy, only a few cases being reported in the medical literature. We present the case of a 49-year-old male patient diagnosed with infected squamous cell urachal carcinoma with multiple pulmonary metastases, after complaints of lower abdominal pain, abdominal mass and fever, without respiratory symptoms. The abdominal ultrasonography and the CT scan revealed a tumoral mass in the lower abdomen in contact with the abdominal wall and the urinary bladder dome, displacing the small bowel. Pulmonary nodular lesions were described in the left lobe pyramid. The intraoperative diagnosis was necrotic urachal tumor with urinary bladder dome invasion and suspected pulmonary metastases, and tumor ablation with bladder dome resection and suture of the bladder were performed. The histopathological result was poorly differentiated squamous cell carcinoma (G3), with negative resection margins. The patient recovered well after surgery, but the prognosis is very poor due to the metastatic stage in which the tumor was diagnosed, no standard chemotherapy regimen for the treatment of metastatic urachal carcinoma being known as effective until now.

BACKGROUND: While hepatocellular carcinoma is a common indication for liver transplantation, intrahepatic cholangiocarcinoma represents a controversial indication for this procedure, due to lower disease-free and overall survival rates achieved by liver transplantation in such patients. Hence, in the last years, few centers reported satisfactory survival rates after liver transplantation for cholangiocarcinoma, in highly selected groups of patients. Herein we present the clinicopathological characteristics, the pre- and postoperative management and the favorable outcome of a patient undergoing liver transplantation for an unresectable intrahepatic cholangiocarcinoma. We consider that reporting the patients with such favorable outcomes is useful, since collecting the data presented by different centers may contribute to identification of a selected group of patients with cholangiocarcinoma who may benefit from liver transplantation. CASE REPORT: A 62-year old female patient with a primary liver tumor developed on HBV liver cirrhosis, was admitted in our center for therapeutical management. Since preoperative work-up suggested that the tumor is an unresectable hepatocellular carcinoma (due to its location and underlying liver disease), we decided to perform liver transplantation. The pathological examination of the explanted liver revealed that the tumor was a stage I intrahepatic cholangiocarcinoma. The postoperative course was uneventful, and in present, 15 months after transplantation, the patient is alive, without recurrence. CONCLUSIONS: Liver transplantation may represent a valid therapeutical option in selected patients with intrahepatic cholangiocarcinoma. Patients with early stage intrahepatic cholangiocarcinomas unresectable due to the underlying liver cirrhosis seem to benefit mostly by liver transplantation. Further studies are needed to identify the favorable prognostic factors in order to select the most appropriate candidates for liver transplantation. The most suitable immunosuppressive and (radio)chemotherapic regimens should be identified in the future, in order to improve the disease-free and overall survival rates of the patients undergoing liver transplantation for intrahepatic cholangiocarcinoma.

INTRODUCTION: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) represent a group of tumors, having their origin in cells of diffuse endocrine system, with particular clinical course, diagnosis and treatment. PATIENTS AND METHODS: In our study, were included 68 patients with neuroendocrine digestive tumors admitted, diagnosed and treated in Fundeni Clinical Institute, Bucharest, in the last ten years--2000-2010 (retrospective study). RESULTS: Thirty-three (49%) patients were males, 35 (51%) females, and the main age was 58.9 years. In 62 (90.3%) cases was possible to find the primary tumor. The examined tumors had different localizations: pancreas--32 (47.04%) cases (head--17 (24.99%) cases, and body and tail--15 (22.05%) cases), stomach--7 (10.29%) cases, small intestine--7 (10.29%) cases, 6 (8.82%) cases--unknown primary site (diagnosis was established on metastases), right colon--6 (8.82%) cases, liver--6 (8.82%) cases, rectum--2 (2.94%) cases, and retroperitoneum--2 (2.94%) cases. Microscopic examination revealed 59 (86.8%) malignant tumors and 9 (13.2%) benign tumors. Using WHO 2000 Classification, 28 cases of malignant tumors were well-differentiated neuroendocrine carcinomas, and 31 cases were poor differentiated neuroendocrine carcinomas. From malignant cases, 25 (42.3%) have distant metastases and 15 (25.9%) lymph node metastases. CONCLUSIONS: Cases of gastroenteropancreatic neuroendocrine tumors included in our study had clinical and histopathological features in correspondence with data from literature--slight predominance in women, predominance in 5th and 6th decades of life, the most frequent localizations were at pancreatic level--both head and body and tail, but the rarest were in colon and retroperitoneum. Most of the cases studied, were malignant tumors, from these more than a half were poor differentiated, and a quarter of them having lymph node or distant metastases.

Thymic epithelial tumors have been traditionally classified into two main types: noninvasive and invasive thymoma. Several classifications have been proposed for thymic tumors, but according to these classifications, the prognosis of patients with thymomas varies considerably. Our purpose is to present different CT aspects according to various subtypes of thymic epithelial neoplasms based on the simplified World Health Organization classification. In this article, we will discuss and illustrate histologic and functional features of the thymus and a spectrum of thymic tumors associated with Myasthenia Gravis. Smooth contours and a round shape are the most suggestive of type A thymic epithelial tumors, whereas irregular contours and heterogeneous enhancement are the most suggestive of type C tumors. Calcifications are suggestive of type B tumors. CT findings may serve as predictors of postoperative recurrence or metastasis for the thymic epithelial tumors.
RESUMO
Neuroendocrine tumors, known as carcinoid tumors constitute a heterogeneous group of neoplasms that present many clinical challenges. They secrete peptides and neuroamines that cause specific clinical syndromes. Assessment of specific or general tumors markers offers high sensitivity in establishing the diagnosis and they also have prognostic significance. Management strategies include curative surgery, whenever possible-that can be rarely achieved, palliative surgery, chemotherapy, radiologic therapy, such as radiofrequency ablation and chemoembolisations and somatostatin analogues therapy in order to control the symptoms. The aim of this paper is to review recent publications in this field and to give recommendations that take into account current advances in order to facilitate improvement in management and outcome.

An important objective in nowadays research is the discovery of new biomarkers that can detect colon tumours in early stages and indicate with accuracy the status of the disease. The aim of our study was to identify potential biomarkers for colon cancer onset and progression. We assessed gene expression profiles of a list of 10 candidate genes (MMP-1, MMP-3, MMP-7, DEFA 1, DEFA-5, DEFA-6, IL-8, CXCL-1, SPP-1, CTHRC-1) by quantitative real time PCR in triplets of colonic mucosa (normal, adenoma, tumoral tissue) collected from the same patient during surgery for a group of 20 patients. Additionally we performed immunohistochemistry for DEFA1-3 and SPP1. We remarked that DEFA5 and DEFA6 are key factors in adenoma formation (p<0.05). MMP7 is important in the transition from a benign to a malignant status (p <0.01) and further in metastasis being a prognostic indicator for tumor transformation and for the metastatic potential of cancer cells. IL8, irrespective of tumor stage, has a high mRNA level in adenocarcinoma (p< 0.05). The level of expression for SPP1 is correlated with tumor level. We suggest that high levels of DEFAS, DEFA6 (key elements in adenoma formation), MMP7 (marker of colon cancer onset and progression to metastasis), SPP1 (marker of progression) and IL8 could be used to diagnose an early stage colon cancer and to evaluate the prognostic of progression for colon tumors. Further, if DEFA5 and DEFA6 level of expression are low but MMP7, SPP1 and IL8 level are high we could point out that the transition from adenoma to adenocarcinoma had already occurred. Thus, DEFA5, DEFA6, MMP7, IL8 and SPP1 consist in a valuable panel of biomarkers, whose detection can be used in early detection and progressive disease and also in prognostic of colon cancer.

Intestinal occlusion due to intussusception produced by intestinal tumors is a very rare condition. Gastrointestinal stromal tumors are also rare digestive neopasias, with an impredictable malignant behavior, which are usually growing outside the intestinal wall, being rarely the initiators of an intestinal intussusception. We present the case of a 59 years old female, admitted in our hospital to elucidate the etiology of her iron deficient anaemia, which developed an intestinal occlusion at the intestinal preparation for colonoscopy. The abdominal CT scan performed in emergency conditions highlighted occlusive intestinal tumor complicated with intestinal intussusception. We performed an emergency laparotomy that revealed intestinal occlusion due to ileo-ileal intussusception produced by an ileal tumor. The surgical intervention consisted in segmental ileal enterectomy including the tumor with latero-lateral entero-enteral anastomosis. The patient recovered without complications. The histopathological and immunohisto-chemical examinations established the diagnose of gastro-intestinal stromal tumor with high risk malignant behavior, therefore the patient was guided in the oncological department for specific treatment and oncological surveillance.

The spleen in rarely the place for solid, non-haematological tumors, isolated splenic metastases from adenocarcinomas being extremely rare findings, regardless of the origin and the histological type of the primary tumor. We present the case of a female patient with isolated splenic metastasis diagnosed by abdominal computer tomography at only 20 months after curative surgery for endometrial adenocarcinoma, in which the final diagnosis has been established by histological and immunohistochemical examination of the splenectomy piece. The haematogenous dissemination of the endometrial cancer occurs most commonly in the lungs, liver or bones, the spleen being rarely affected. In the medical literature there are cited up to date only 12 cases of solitary splenic metastasis from endometrial adenocarcinoma. The particularity of the case presented by us is the early appearance of an isolated splenic metastasis, at less than two years after curative surgery (compared to an average of 4-5 years cited in the literature), from an endometrial cancer which was classified histologicaly in the group with low-risk for relapse (well differentiated endometrioid adenocarcinoma). In conclusion, although solitary splenic secondary determinations are very rare, the incidence of the reported cases in the medical literature is increasing, their late appearance (a few years after the primary tumor's resection) and the lack of symptoms until the tumor reaches appreciable size or it complicates with necrosis, justifies the periodic abdominal imaging examination, on long-term, for postoperative monitorisation after the initial curative surgery. Their treatment of choice is open, classical splenectomy that must be followed by chemotherapy in order to prevent the development of other possible micrometastases.

INTRODUCTION: Transabdominal routes for surgery entail general anaesthesia with its inherent risks and complications (prolonged hospital stay, abdominal incisions that may be difficult in obese patients). Minimally invasive procedures require shorter hospitalization, have shorter recovery periods, less postoperative discomfort, and lower morbidity and complications. The purpose of this study was to use a porcine model to determine the feasibility and the safety of organ resection (oophorectomy and tubectomy). MATERIALS AND METHODS: 10 Big White pigs between 25-30 kg underwent transgastric ooforectomy. The first 5 cases were performed in a hybrid procedure (laparoscopic-NOTES) in order to have a better control and supervise the maneuvers done by the mobile endoscope and to guide in the abdominal cavity. RESULTS: Adnexectomy was possible in all ten experiments. Full operative time (from starting endoscopy to complete gastrectomy closing) was 180 min to 270 min. The gastric defect closing was the most difficult manoever lasting from 10 min with OTSC clips to 100 using endoloops and clips. The animals have tolerated well the experiments and there have been no remarkable incidents during our 10 experments. In only one case a bleeding from gastotomy required electric coagulation. CONCLUSION: Transgastric ooforectomy in an experimental model is a procedure that requires advanced laparoscopical and endoscopical skills. Our early results are promissing. Its application in humans needs further confirmation of the method.

INTRODUCTION: Initially considered experimental, liver transplantation (LT) has become the treatment of choice for the patients with end-stage liver diseases. MATERIAL AND METHODS: Between April 2000 and October 2009, 200 LTs (10 reLTs) were performed in 190 patients, this study being retrospective. There were transplanted 110 men and 80 women, 159 adults and 31 children with the age between 1 and 64 years old (mean age--39.9). The main indication in the adult group was represented by viral cirrhosis, while the pediatric series the etiology was mainly glycogenosis and biliary atresia. There were performed 143 whole graft LTs, 46 living donor LTs, 6 split LTs, 4 reduced LTs and one domino LT RESULTS: The postoperative survival was 90% (170 patients). The patient and graft one-year and five-year survivals were 76.9%, 73.6% and 71%, 68.2%, respectively. The early complications occurred in 127 patients (67%). The late complications were recorded in 71 patients (37.3%). The intraoperative and early postoperative mortality rate was 9.5% (18 patients). CONCLUSIONS: The Romanian liver transplantation program from Fundeni includes all types of current surgical techniques and the results are comparable with those from other international centers.

Distal pancreatectomy (DP) is the removal of the pancreatic tissue at the left side of the superior mesenteric vein and it is traditionally approached by an open or laparoscopic exposure. Preservation of the spleen is optional but appears to have a better immunological outcome. We present the case of a 53-year old patient with a 2.4/2.2 tumor located in the tail of the pancreas, with high tumour marker values for whom we decided to perform a robotic spleen-preserving distal pancreatectomy (RSPDP). The postoperative outcome was satisfactory. In conclusion, we recommend this type of approach for small pancreatic tail lesions.
