RESUMO

Background Nerve growth factor (NGF) is a novel target of pain therapeutics for oral cancer, and it plays a main role in the nociception of chronic pain. Surgery, along with chemotherapy or radiotherapy, is the gold standard for treating patients, but the side effects are significant as well. Newer effective interventions with natural phytochemicals could improve patient compliance and enhance the quality of life among patients with oral cancer. A literature search revealed a positive correlation between NGF and oral cancer pain. Nigella sativa (N. sativa) and Cuscuta reflexa (C. reflexa) have proven anticancer effects, but their activity with NGF is unexplored. Aims and objectives We aimed to identify the potential phytochemicals in N. sativa and C. reflexa. We also checked the NGF-blocking activity of the phytochemicals. Molecular docking and molecular dynamic (MD) simulations evaluated the binding energy and stability between the NGF protein and selected phytochemical ligands. Materials and methods We obtained protein NGF structure from UniProt (ID: 4EDX, P01138, Beta-nerve growth factor), ligand (thymoquinone) structure using PubChem ID: 10281, and ligand (cuscutin) structure using PubChem ID: 66065. Maestro protein (Schrödinger Inc., Mannheim, Germany) was used for molecular docking. Desmond Simulation Package (Schrödinger Inc., Mannheim, Germany) was used to model MD for 100 nanoseconds (ns). We have assessed the interaction between the protein and ligands by root mean square deviation (RMSD) values.  Results The interaction of thymoquinone and cuscutin with NGF was assessed. While interacting with thymoquinone, there was mild fluctuation from 0.6 Å to 2.5 Å up to 80 ns and ended up at 4.8 Å up to 100 ns. While interacting with cuscutin, mild fluctuation was seen from 0.8 Å to 4.8 Å till 90 ns and ended at 6.4 Å up to 100 ns. We found a stable interaction between our drug combination and the NGF receptor. Conclusion We have identified a stable interaction between thymoquinone, cuscutin, and NGF by our MD simulations. Hence, it could be used as an NGF inhibitor for pain relief and to control tumor progression. Further in vitro and in vivo evaluations of this novel drug combination with phytochemicals will help us understand their biological activities and potential clinical applications in oral cancer therapeutics.

RESUMO

MIRAGE syndrome consists of Myelodysplasia, Infection, Growth restriction, Adrenal hypoplasia, Genital phenotypes, and Enteropathy. We report the uneventful anesthesia management of a 6-year-old female patient with MIRAGE syndrome. We think it can guide anesthesiologists caring for patients with this syndrome to find the appropriate method for them.

RESUMO

The proper regulations for storage, retention, and use of archived specimens in pathology laboratories and academic institutions are yet to be established. These specimens could be used appropriately for research purposes. Ideal storage and retention in a controlled environment is necessary, and there is a lack of established rules regarding the ownership of the tissue specimens, paraffin blocks, and slides. Though there are numerous uses of formalin-fixed tissue specimens, blocks, and slides, there are also problems in archiving them that hinder their use. This review article addresses the above issues and proposes simple guidelines for the effective use of archived specimens.

RESUMO

BACKGROUND: Black cumin/Nigella sativa is traditionally used for its wide range of medicinal effects. Clove/Syzygium aromaticum is well known as a natural antibiotic with antiviral, antibacterial, and antifungal properties, and onion/Allium cepa for its antibacterial properties. The combination of these extracts can effectively have many therapeutic applications. AIM: The aim of the present study is to prepare the formulation of N. sativa, S. aromaticum, A. cepa and to assess the antimicrobial activity and cytotoxic effect of the prepared formulation. MATERIALS AND METHODS: Antimicrobial activity was carried out by agar well diffusion method and cytotoxic activity was carried out using the brine shrimp lethality assay method. RESULTS: The antimicrobial activity showed the zone of inhibition was highest with Staphylococcus aureus showing 22 mm of zone of inhibition at 100 µl. The cytotoxicity test showed there are about 90% live nauplii in the lowest concentration at 5 µl. CONCLUSION: The study concluded that the combination extract of N. sativa, S. aromaticum, and A. cepa could be used as an antimicrobial agent. Further research with pathogenic oral microorganisms can validate this formulation as an antimicrobial gel or mouthwash for various pathologies.

RESUMO

OBJECTIVE: To assess differences based on gender in nuclear area (NA), cytoplasmic area (CA), and nuclear-cytoplasmic ratio (N:C ratio) values for clinically normal buccal smears in apparently healthy subjects of a South Indian population, thereby providing definitive baseline cytomorphometric measurements for the South Indian population. METHODS: Buccal smears were collected from 60 healthy subjects (30 males and 30 females) of a South Indian population above 18 years in age. Values of the NA and CA were measured, and the N:C ratio calculated, using ImageJ software. Statistical analysis of the data with independent t tests and 95% confidence intervals was done using SPSS version 21 (significance set at P < 0.05). RESULTS: The results showed that there were significant differences in the NA, CA, and N:C values between males and females irrespective of age (P = 0.01). CONCLUSION: Definitive gender-specific baseline cytomorphometric data can be established using exfoliative cytology for the South Indian population, and this may be helpful in deciphering the occurrence of oral pre-malignant diseases and oral squamous cell carcinoma in this population, as the incidence of these conditions varies with gender and different ethnic groups.

RESUMO

The emergence of multi-drug resistant (MDR) bacterial strains, which are posing a global health threat has developed the interest of scientists to use bacteriophages instead of conventional antibiotics therapy. In light of an increased interest in the use of phage as a bacterial control agent, the study aimed to isolate and characterize lytic phages from sewage effluent. During the current study, bacteriophage AS1 was isolated from sewage effluent against E.coli S2. The lytic activity of phageAS1 was limited to E.coli S2 strain showing monovalent behavior. The calculated phage titer was 3.5×109 pfu/ml. PhageAS1 was stable at a wide range of pH and temperature. The maximum stability was recorded at 37ºC and pH 7.0, while showing its normal lytic activity at temperature 60ºC and from pH 5.0 to11.0 respectively. At temperature 70ºC, phage activity was somewhat reduced whereas, further increase in temperature and decrease or increase in pH completely inactivated the phage. From the current study, it was concluded that waste water is a best source for finding bacteriophages against multi-drug resistant bacterial strains and can be used as bacterial control agent.

Durante o estudo atual, o bacteriófago AS1 foi isolado de efluente de esgoto contra E. coli S2. A atividade lítica de phageAS1 foi limitada à cepa E. coli S2, apresentando comportamento monovalente. O título de fago calculado foi de 3,5 x 109 ufp/ml. PhageAS1 foi estável em uma ampla faixa de pH e temperatura. A estabilidade máxima foi registrada a 37ºC e pH 7,0, enquanto mostrou atividade lítica normal em temperatura de 60ºC e pH 5,0 a 11,0, respectivamente. Na temperatura de 70ºC, a atividade do fago foi um pouco reduzida, enquanto o aumento adicional da temperatura e a diminuição ou aumento do pH inativaram completamente o fago. Com base no estudo atual, concluiu-se que a água residual é a melhor fonte para encontrar bacteriófagos contra cepas bacterianas multirresistentes e pode ser usada como agente de controle bacteriano.

RESUMO

Aromatase is involved in the biosynthesis of estrogen and thus is a critical target for breast cancer. In this study, to identify new aromatase enzyme inhibitors, seven 3-[4-(5-methyl-1H-benzo[d]imidazol-2-yl)phenyl]-6-(substituted phenyl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazine derivatives were synthesized. First, a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was performed to determine the inhibitory activity of the synthesized compounds on the MCF-7 cell line. The aromatase inhibitory activity was determined for the active compounds 5b, 5c, 5e, and 5g on the MCF-7 cell line. Compound 5g showed significant aromatase inhibitory activity (IC50 = 0.037 ± 0.001 µM). Interestingly, this compound, which bears a difluoro substituent at positions 2 and 4 of the phenyl ring, displayed the most potent aromatase inhibitory activity without significant cytotoxicity to a normal healthy cell line (NIH3T3). Furthermore, the interactions between the best active compounds and the active site of the enzyme were analyzed through a docking study. The results of this study determined that benzimidazole-triazolothiadiazine derivatives are promising compounds that should be further developed as a novel class of aromatase inhibitors.

RESUMO

BACKGROUND: Economic models in oncology are commonly based on the three-state partitioned survival model (PSM) distinguishing between progression-free and progressive states. However, the heterogeneity of responses observed in immuno-oncology (I-O) suggests that new approaches may be appropriate to reflect disease dynamics meaningfully. MATERIALS AND METHODS: This study explored the impact of incorporating immune-specific health states into economic models of I-O therapy. Two variants of the PSM and a Markov model were populated with data from one clinical trial in metastatic melanoma patients. Short-term modeled outcomes were benchmarked to the clinical trial data and a lifetime model horizon provided estimates of life years and quality adjusted life years (QALYs). RESULTS: The PSM-based models produced short-term outcomes closely matching the trial outcomes. Adding health states generated increased QALYs while providing a more granular representation of outcomes for decision making. The Markov model gave the greatest level of detail on outcomes but gave short-term results which diverged from those of the trial (overstating year 1 progression-free survival by around 60%). CONCLUSION: Increased sophistication in the representation of disease dynamics in economic models is desirable when attempting to model treatment response in I-O. However, the assumptions underlying different model structures and the availability of data for health state mapping may be important limiting factors.

RESUMO

This prospective observational study was carried out in the Infertility Unit, Department of Obstetrics and Gynaecology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, from February 2011 to December 2013. Sixty-nine (69) subfertile women who were seropositive for Chlamydia Trachomatis were included in this study. Inclusion criteria was patients with sub-fertility having age between 22 and 40 years, seeking infertility treatment, normal ovarian function, all normozoospermic male partner, duration of infertility ranged from 1.5 to 14 years. Exclusion criteria were patients having sub-fertility with extensive pelvic and/or ovarian surgery, endometriosis, ablation of endometriotic spots, pelvic tuberculosis and history of ectopic pregnancy. Before laparoscopic evaluation, all study women were screened for Chlamydia Trachomatis Specific IgG & IgM antibodies using ELISA in the Microbiology Department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. All the study women had positive results for IgG antibodies. All study women underwent diagnostic laparoscopy. During laparoscopy, we observed the condition of pelvic cavity, uterus, fallopian tubes, ovaries, peritubal adhesions, tubo-ovarian relationship, status of Pouch of Douglas (POD), fimbriae etc. During dye test procedure, dilute methylene blue dye was injected through the cervical canal and the dye spill out was observed to confirm the tubal patency or blockage or pattern of flow of dye. The results of laparoscopic findings demonstrated that mobility of uterus was restricted in 20(29%) cases, adhesion of uterus with peritoneum was in 8(11.6%) cases, uterine fibroid was present in 11(15.9%) cases, hydrosalpinx in right fallopian tubes were in 27(39.1%) cases, in left fallopian tubes were in 32(46.4%) cases and in both fallopian tubes in 16(23.2%) cases, inflamed right fallopian tubes in 32(46.4%) cases, inflamed left fallopian tubes in 36(52.2%) cases and inflamed both fallopian tubes in 26(37.7%) cases, adhesions in pouch of Douglas was in 4(5.8%) cases, collections in pouch of Douglas was in 7(10.1%) cases and obliterations in pouch of Douglas was in 5(7.2%) cases. Results of Dye test during laparoscopy were that right fallopian tube was blocked in 32(46.4%) cases, left fallopian tube was blocked in 32(46.4%) cases and both fallopian tubes were blocked in 21(30.4%) cases. This study shows that by laparoscopy, significant number of cases of tubal and pelvic pathology was diagnosed in the chlamydia trachomatis seropositive subfertile female. This indicates strong correlation between seropositivity of chlamydia trachomatis and/or pelvic pathology detected by diagnostic laparoscopy.

RESUMO

AIMS: This study aimed to evaluate the effect of five cadmium-tolerant endophytic plant growth-promoting bacteria (PGPB) strains on the biomass and cadmium tolerance, and accumulation of the bioenergy plant switchgrass (Panicum virgatum L.) under cadmium (Cd)-contaminated conditions. METHODS AND RESULTS: Five bacterial strains (Bj05, Le14, Ps14, So02 and Bo03) that could tolerate up to 2000 µmol l-1 CdCl2 with a high Cd-binding capacity were isolated from plants grown in Cd-contaminated soil. These strains could promote the growth of switchgrass in the presence of 20 µmol l-1 CdCl2 . Under Cd stress, both the root and shoot length and biomass in two switchgrass cultivars, Alamo and Cave-in-Rock (CIR), increased significantly after treatment with PGPB (P ˂ 0·05). Of the five PGPB strains, Bj05 and Le14 most effectively alleviated the Cd-induced growth inhibition of Alamo plants. Interestingly, the five PGPB strains increased Cd tolerance and decreased the accumulation and translocation factor (TF) of Cd in switchgrass when grown in the presence of 20 µmol l-1 CdCl2 . The Cd concentrations in roots and shoots of Alamo and CIR plants were significantly reduced (P Ë‚ 0·05) compared with noninoculated plants. By 16S rRNA sequencing, these PGPB strains were classified as Pseudomonas putida Bj05, Pseudomonas fluorescens Ps14, and Enterobacter spp. Le14, So02 and Bo03. CONCLUSION: Inoculation with PGPB protects plants from the inhibitory effects of Cd, improves plant growth and decreases Cd concentration. These observations suggest that these strains could be used to promote growth and lower the bioavailability of Cd in switchgrass. SIGNIFICANCE AND IMPACT OF THE STUDY: These strains are potential candidates for the development of low Cd-accumulating switchgrass, particularly in areas of Cd contamination and pollution, and could be used efficiently for the bioremediation of contaminated soil.

RESUMO

Neuroendocrine neoplasms (NEN) represent a group of potentially malignant tumors, which can be located in every section of the gastrointestinal tract, the pancreas and the bronchopulmonary system. Gastroduodenal NENs have a relatively good prognosis in comparison to other subentities, e.g. pancreatic or ileojejunal NENs. In the stomach there are four different types of NENs, while in the duodenum there are five types and all vary in the malignant potential and the therapeutic approach. Due to the simple access endoscopic methods not only have diagnostic but also important therapeutic relevance in this subgroup. Lesions smaller than 1 cm can easily be resected with forceps or snare resection and for larger lesions up to 2 cm more invasive strategies, such as endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) are available. Important criteria in gastric NEN for the risk evaluation of endoscopic treatment alone are the size of the lesion, depth of invasion and the tumor biology, e.g. neuroendocrine tumor (NET) G1/G2 versus neuroendocrine carcinoma (NEC) G3. In duodenal NEN the aforementioned risk factors also apply and in addition only lesions outside the ampulla of Vater should be endoscopically resected whereas periampullary lesions need to be addressed surgically. As an individualized therapeutic approach the possibility of a combined endoscopic and laparoscopic resection technique exists. Follow-up endoscopic investigations are necessary, especially in gastric type 1 NENs, which have a tendency to relapse.

RESUMO

BACKGROUND: Variations in systemic inflammatory response biomarker levels have been associated with adverse clinical outcome in various malignancies. This study determined the prognostic significance of preoperative neutrophil:lymphocyte (NLR), platelet:lymphocyte (PLR) and monocyte:lymphocyte (MLR) ratios in endometrial cancer. METHODS: Clinicopathological and 5-year follow-up data were obtained for a retrospective series of surgically treated endometrial cancer patients (n=605). Prognostic significance was determined for overall (OS) and cancer-specific survival (CSS) using Cox proportional hazards models and Kaplan-Meier analysis. Receiver-operator characteristic and log-rank functions were used to optimise cut-offs. NLR, PLR and MLR associations with clinicopathological variables were determined using non-parametric tests. RESULTS: Applying cut-offs of ⩾2.4 (NLR), ⩾240 (PLR) and ⩾0.19 (MLR), NLR and PLR (but not MLR) had independent prognostic significance. Combining NLR and PLR scores stratified patients into low (NLR-low and PLR-low), intermediate (NLR-high or PLR-high) and high risk (NLR-high and PLR-high) groups: multivariable hazard ratio (HR) 2.51; P<0.001 (OS); HR 2.26; P<0.01 (CSS) for high vs low risk patients. Increased NLR and PLR were most strongly associated with advanced stage (P<0.001), whereas increased MLR was strongly associated with older age (P<0.001). CONCLUSION: Both NLR and PLR are independent prognostic indicators for endometrial cancer, which can be combined to provide additional patient stratification.

RESUMO

In developing countries, abdominal myomectomy is still a modality of treatment for large and symptomatic uterine fibroid in women who wish to retain their fertility and preserve uterus. In order to assess the outcome of pregnancies after myomectomy, a prospective observational study was carried out in the Department of Obstetrics and Gynaecology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, from July 1999 and June 2011. Study included 40 married women of reproductive age, suffering either from primary or secondary subfertility, and who had uterine fibroid and strongly wished to conceive shortly after myomectomy using microsurgical procedure with no existence of other male and female subfertility factor. These women were followed up at 3, 6, 12 and 24 month intervals over telephone and outdoor visits. Data were recorded on preformed questionnaires. Post myomectomy hysterosalpingography was done at about 16 weeks after myomectomy. Patients were advised to try for pregnancy after 16 weeks of operation. Maximum number of women belonged to age group 31-35 years (n=14, 35%); primary subfertility was 67.5% and secondary 32.5%; in maximum number of cases duration of subfertility was 2-5 years (n=22, 55%); type of fibroid were solitary (52.5%) and multiple (47.5%); type of myoma were intramural (75%), submucous (2.5%) and combined (22.5%); location of myoma were fundal (5%), anterior wall (25%), posterior wall (20%) and combined (50%); diameter of removed myoma were <5cm (2.5%), 5-8cm (67.5%), >8-10(20%) and >10cm (10%); uterine size before myomectomy were (in weeks) <12(22.5%), 12-14 (27.5%), 15-20 (32.5%), 21-25 (15%) and >25 (2.5%). Hysterosalpingography was done in 16(40%) cases, and the findings were both tube patent (62.5%), unilateral tubal block (31.2%) and bilateral tubal block (6.2%). Menorrhagia after myomectomy was present only in 5% cases. After uterine myomectomy, 14(35%) women conceived, common time interval between myomectomy and conception was 1-2 years (42.9%), conception was spontaneous in 71.4%.

RESUMO

Portal hypertension which usually leads to bleeding from oesophageal varices in children remain a difficult medical problem. The upper gastrointestinal endoscopy is currently considered as the best reliable method to diagnose oesophageal varices in portal hypertension. But endoscopic screening is an invasive procedure and is not easily available even in tertiary health care facilities of Bangladesh till now. Therefore an alternative noninvasive indicator is being looked for the diagnosis of portal hypertension. Patients with serum ascites albumin gradient (SAAG) values ≥1.1gm/dl have recently found to have presence of portal hypertension. The study was carried out to set up a diagnostic value of SAAG for the prediction of portal hypertensive changes (oesophageal and gastric varices, gastropathy) of upper gastrointestinal endoscopy in children. This cross sectional study was conducted at the Department of Paediatric Gastroenterology and Nutrition of Bangabandhu Sheikh Mujib Medical University. A total of 30 cases of portal hypertension were studied from November 2008 to February 2010. Oesophageal varices were found in 86.7% of cases. Significant association was found between high SAAG values and presence of oesophageal varices. Frequencies of oesophageal varices increased as the SAAG values increased. The cut off point of SAAG value was found to be 1.55gm/dl for the presence of oesophageal varices where sensitivity and specificity were found 84.6% and 100 % respectively. From this study, it can be concluded that SAAG value 1.6gm/dl is an indicator of portal hypertensive changes especially oesophageal varices in children.

RESUMO

Polycystic ovarian syndrome (PCOS) has a pivotal role in the development of various complications during pregnancy. Polycystic ovarian syndrome women having elevated LH and hyper insulineuia may be at increased risk of miscarriage. The study was done to find out the recurrent pregnancy loss among the PCOS patient. This was a cross sectional case control study in total 100 infertile patients between age 20-40 years attending BSMMU out patient Department from July 2011 to June 2012, among them 50 infertile patients with PCOS regarding as a case and 50 infertile patients without PCOS selected as a control. Regarding case (infertile patients with PCOS) shows 20(40%) recurrent miscarriage and among control (infertile patients without PCOS) shows recurrent miscarriage 6(12%). And also among case group shows insulin resistance 8(16%) and control group insulin resistance 1(2%). Six (75%) abortion occur among PCOS with insulin resistance and 5(62.5%) abortion occur among PCOS with raised testosterone level. It is observed that recurrent miscarriage is higher in PCOS group. And also concluded that insulin resistance and raised testosterone level is responsible for this condition. So, further large scale study would be needed to reduce the chance of recurrent pregnancy loss by treatment with insulin sensitizer in case of obese PCOS with insulin resistance patient.

RESUMO

Neuroendocrine neoplasms (NEN) of the distal jejunum and ileum derive from serotonin-producing enterochromaffin (EC) cells. Due to their low proliferation rate and their infiltrative growth, they are often discovered at an advanced disease stage when metastasis has already occurred. The biology of these tumours is different from other NEN of the digestive tract. In order to standardise and improve diagnosis and therapy, the guidelines for the diagnosis and clinical management of jejuno-ileal NEN as well as for the management of patients with liver and other distant metastases from NEN were revised by the European Neuroendocrine Tumour Society (ENETS) in 2012. This review focuses on aspects relevant for surgical pathology.

RESUMO

INTRODUCTION: The gastric and duodenal perforations are a life-threatening complication of peptic ulcer disease with the indication for immediate surgical intervention. To which extent laparoscopy is a suitable method in an acute situation was examined in the present investigation. MATERIALS AND METHODS: The data of all patients within a period of 15 years (01/1996-12/2010) who were operated laparoscopically because of a perforated gastric or duodenal ulcer, were collected prospectively in terms of age, gender, localisation of perforation, diagnostics, symptoms, surgical procedures, intraoperative and postoperative complications and postoperative course, and were analysed retrospectively. RESULTS: During the observation period 45 patients were operated laparoscopically due to gastric or duodenal perforation. The median age at operation was 58 (18-91) years. An NSAID medication was present in 11 (24.4 %) patients. The perforation was juxtapyloric in 12 (26.7 %) patients, postpyloric in 10 (22.2 %) patients, one (2.2 %) patient in each small and greater curvature, in 18 (40.0 %) at the front and in three (6.7 %) patients on the rear wall. In two cases, previous surgical treatment in the upper abdomen was performed. After primary diagnostic laparoscopy, an indication for conversion was seen in 20 (44.4 %) patients. During laparoscopically completed operations simple suturing was done in 18/25 (72.0 %) patients and excision and suturing was performed in 7/25 (37.8 %) patients. After conversion simple suturing was observed in 7/20 (35.0 %) patients, whereas in 10/20 (50.0 %) patients excision and suturing was performed. 3/20 (15.0 %) patients underwent a resective operation. The median operative time was 105 (40-306) minutes and mean hospitalisation 11 (4-66) days. The ICU stay was in median 2 (0-37) days. Major complications were seen in 11 (24.4 %) patients, namely re-laparotomy (n = 7; 15.6 %) and haemorrhage (n = 4; 8.9 %). Minor complications were observed in 8 (17.8 %) of cases. The mortality rate was 11.1 % (n = 5). CONCLUSION: The laparoscopic treatment of gastric and duodenal perforations is a minimally invasive therapeutic option for the definitive treatment of this life-threatening disease. The indication for a laparoscopic approach has to be considered individually and depends to a decisive extent on the experience of the laparoscopic surgeon.

RESUMO

BACKGROUND: Neuroendocrine neoplasia (NEN) are a rare and heterogenous tumour entity. The subgroup with unknown primary tumour (N-CUP) seems to have a worse prognosis as resection of the primary is necessary for cure. The diagnostics and therapeutic algorithms for N-CUP in a German single centre are presented. PATIENTS/METHODS: Analysis of the surgical databank showed 35 cases of N-CUP in 261 cases with NEN from gastroenteropancreatic and lung origin over 2 decades (03/1990-03/2011). Three groups were built: K1 - primary detection after operative exploration (n = 10), K2 - unknown primary after operative exploration (n = 10) and K3 - no operative exploration for various reasons (n = 13). RESULTS: Initially 13.4 % (35/261) of patients presented as N-CUP, after intensified diagnostics 12.7 % (33/261) and after operative exploration 8.8 % (23/261) remained with unknown primary tumour. The sex ratio was 1 : 1, the median age is significantly higher in N-CUP [63.8 years (y) vs. 55.9 y, p = 0.004), the 5-year-survival is lower (58 vs. 72 %, n. s.). compared to NEN with known primary. Operative exploration was performed in 60.6 % (20/33), 30 % (6/20) of them were found to have inoperable situations, in 20 % (4/20) single site metastases were removed completely and in 50 % (10/20) a primary tumour was detected (8 × midgut, 2 × pancreas) intraoperatively. In these cases 70 % (7/10) got complete tumour resection (R0) and in 30 % (3/10) primary tumour resection with debulking of liver metastasis was done. In K3 (39.4 %, 13/33) most patients [69.2 % (9/13)] were treated with chemotherapy. The median age in K1 was significantly lower than in K3 (54.9 y vs. 68.3 y, p = 0.028), male dominance was seen in K3 (3,3 : 1, n. s.). The average Ki-67 index was 4.3, 23.8 and 53 % in K1, K2 and K3 (p < 0.0001 for K1 and K3 and p = 0.035 for K2 and K3), respectively. The death rate was 20, 30 and 76.9 % in K1, K2 and K3, respectively. CONCLUSION: Primary tumours of the midgut and pancreas are often found in the subset of well differentiated neuroendocrine CUP syndrome after open surgical exploration. A high rate of complete tumour resection and cure can be achieved in these cases. After common diagnostic tools (CT, MRI and somatostatin receptor scintigraphy), immunhistochemistry can give important hints (CDX-2 for midgut, TTF-1 for lung and thyroid) for a primary lesion. Also in single site metastasis without primary tumour detection a good clinical outcome is seen after complete resection.
