The risk of lymph node metastases and their impact on survival in patients with appendiceal neuroendocrine neoplasms: a systematic review and meta-analysis of adult and paediatric patients. Endocrine 2020; 67:20-34. [PMID: 31493274 PMCID: PMC6969007 DOI: 10.1007/s12020-019-02072-y] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2019] [Accepted: 08/21/2019] [Indexed: 12/16/2022]
Abstract
BACKGROUND There are no clear histopathological parameters determining the risk of lymph node (LN) metastases and appropriateness of completion prophylactic right hemicolectomy (RHC) in patients with appendiceal neuroendocrine neoplasms (ANENs). MATERIALS AND METHODS The PubMed, Cochrane Library, Embase, Web of Science and SCOPUS databases were searched up to November 2018. Quality/risk of bias was assessed using the Newcastle-Ottawa Scale (NOS). RESULTS A total of 526 articles were screened. In 11 adult and 3 paediatric studies, 602 and 77 unique patients, respectively, with ANEN and undergoing RHC, were included. The rate of LN metastases for a cutoff size >10 mm was 48.6% (vs 12.1% for lesions <10 mm) among adult patients, with an odds ratio (OR) of 4.8 (95% CI, 1.5-15.8). For 20 mm size cutoff, these figures were 61% (vs 28.2% for lesions <20 mm) with an OR of 3.2 (95% CI, 1.3-7.8). Vascular-, lymph vessel- and perineural invasions were identified as predictive factors for LN metastases in adult patients. In paediatric patients, there were no strong morphological predictors for LN metastases. The 10-year disease-specific survival (DSS) for adult patients without LN metastases was 99.2% vs 95.6% in patients with LN (OR: 0.2; 95% CI, 0.02-2.4). The complication rate of prophylactic RHC was 11.4%. CONCLUSIONS This meta-analysis demonstrates that tumour size >20 mm as well as >10 mm and/or vascular-, lymph vessel- and perineural invasions are associated with increased risk for LN metastases in adult patients with ANEN. The prognostic value of LN positivity remains to be determined in further studies with long-term follow-up.

Abstract
Adenocarcinoma ex-goblet carcinoid (ADA ex-GCC) is a rare and aggressive subtype of goblet cell carcinoid, a distinct tumor of the appendix characterized by both neuroendocrine and glandular differentiation. Patients often present with chronic abdominal pain or symptoms of acute appendicitis. Right hemicolectomy is the primary mode of treatment, and prophylactic salpingo-oophorectomy and hysterectomy is recommended in post-menopausal women due to the tumor's propensity of transcoelemic spread, especially to the ovaries. In this case report, we describe a patient with ADA ex-GCC who was found to have oligometastic disease in the pelvis and treated with hypofractionated stereotactic body radiation therapy (HSRT). She initially underwent a right hemicolectomy followed by adjuvant capecitabine four years prior when her tumor was incidentally discovered on colonoscopy. She subsequently had a salpingo-oophorectomy for gynecologic tract metastatic disease and declined further chemotherapy. The patient was again discovered to have oligometastatic disease in the right pelvis adjacent to the rectum on a Gallium-68 dotatate PET/MRI, and was subsequently treated with HSRT to 39 Gy in 6.5 Gy daily fractions. The patient tolerated her radiation course without notable radiation-related toxicity, and she remains without disease progression nine months later.

Abstract
Ulcerative colitis (UC) is a known risk factor for colorectal cancer, but the association between UC and appendiceal adenocarcinoma remains rare. We present a 42-year-old patient with long-standing UC who presented with acute appendicitis shortly after a routine colonoscopy. Histopathological examination revealed moderately differentiated appendiceal adenocarcinoma. The recognition of appendiceal cancer as a complication of long-standing UC warrants increased clinical awareness.

Abstract
Aim: To characterize the epidemiology of appendiceal mucinous adenocarcinoma. Methods: Prognostic factors were evaluated with univariate and multivariate analyses. The results were used to generate a nomogram. Results: The incidence of appendiceal mucinous adenocarcinoma showed a significant upward trend. Multivariate Cox analysis identified 11 independent prognostic factors. The nomogram was based on independent risk factors that were significant in multivariate Cox analysis, and the concordance-index for overall survival and cancer-specific survival were 0.76 (95% CI: 0.71-0.79) and 0.74 (95% CI: 0.70-0.79), respectively. Conclusion: Advanced age, single relationship status, male sex, black race, the presence of distant and regional lymph node metastases, poor differentiation or lack of differentiation, advanced SEER extent of disease, cancer-directed surgery and chemotherapy were independently associated with prognosis.

Abstract
BACKGROUND Goblet cell carcinoid (GCC) tumors of the appendix are a rare malignancy. We aim to examine the overall survival per stage and the relationship between different treatment modalities and outcomes for patients with GCC tumors of the appendix. METHODS We identified patients with GCC tumors of the appendix from the National Cancer Database. The main outcome was overall patient survival and cox proportional hazard models were used to ascertain predictors of survival. RESULTS There were 2552 patients identified. The median age of diagnosis was 57 (interquartile range: 49-65) and 52.3% of patients were female. The 5-year survival for Stage I disease was 91.1% (95% confidence interval [CI]: 82.2%-95.7%), for Stage II disease was 90.5% (95% CI: 85.8%-93.7%), for Stage III disease was 57.0% (95% CI: 45.0%-67.3%), and for Stage IV disease was 18.9% (95% CI: 9.3%-31.0%). In a Cox proportional hazard model, older age (hazard ratio [HR]: 1.1; 95% CI: 1.03-1.12; P < .001), lymph node metastasis (HR: 6.9; 95% CI: 2.76-17.01; P < .001), and positive surgical margins (HR: 2.9; 95% CI:1.13-7.26; P = .003) were associated with worse overall survival for Stages I to III disease while only older age (HR: 1.03; 95% CI: 1.002-1.06; P = .04) was associated with worse overall survival for Stage IV disease. CONCLUSIONS Patients with GCC tumors of the appendix who have the nonmetastatic disease have a high 5-year survival. We have identified several prognostic factors for GCC.

Abstract
AIM Appendiceal mucinous neoplasms are rare, and thus the literature is sparse with regard to histological types, staging, and prognosis. In particular, it is unclear how long-term outcome may differ between mucinous adenocarcinomas and other adenocarcinomas. In the present study, we aimed to investigate the histological types and stages of appendiceal neoplasms, and to evaluate the prognostic impacts of these factors in patients with mucinous adenocarcinomas and non-mucinous adenocarcinomas. METHODS Patients with appendiceal tumors diagnosed between 2007 and 2016 were retrospectively identified from the databases of 19 institutions in the Clinical Study Group of Osaka University, Colorectal Group. RESULTS A total of 266 patients with appendiceal tumors were identified, of whom 130 had pathologically diagnosed adenocarcinomas, including 57 with mucinous adenocarcinomas and 73 with non-mucinous adenocarcinomas. Five-year overall survival (OS) rates were 64.5% for mucinous adenocarcinomas, and 49.0% for non-mucinous adenocarcinomas. OS was significantly shorter among patients with non-mucinous adenocarcinomas compared to mucinous adenocarcinomas. Among patients with mucinous adenocarcinomas, 5-year OS rates were 53.6% for stage 0/I, 82.6% for II/III, and 48.4% for IV. Among patients with non-mucinous adenocarcinomas, 5-year OS rates were 90.9% for stage 0/I, 68.8% for II/III, and 7.1% for IV. Analysis of patients with stage IV disease revealed significantly shorter OS among patients with non-mucinous adenocarcinomas compared to mucinous adenocarcinomas. CONCLUSION Our present findings showed a better prognosis in patients with mucinous adenocarcinomas compared to non-mucinous adenocarcinomas. In this setting, Union for International Cancer Control staging was associated with prognosis for non-mucinous adenocarcinomas, but not for mucinous adenocarcinomas.

Abstract
Primary appendicular adenocarcinoma is a rare tumor, mucinous variety, being most common. The case presentation highlights the unusual appearance and diagnostic dilemma of an appendicular adenocarcinoma. Our elderly patient presented with an ill-defined tender lump which later was diagnosed as a perforated appendicular adenocarcinoma, responsive to single-staged surgery and adjunct chemotherapy. We considered the single-staged surgery since the appendix was perforated and right colectomy would not aid the prognosis. High index of clinical suspicion for malignancy should be kept in mind for elderly patients presenting with an appendicular lump. Every effort should be made during the elective surgery to remove the mass during the single-staged surgery.

Abstract
For gastrointestinal endoscopists, the ileocecum is the finishing line during colonoscopy and it is identified by three endoscopic landmarks: terminal ileum, ileocecal valve, and the appendiceal orifice. Although ileal intubation is recommended during routine screening colonoscopy, it is not required in most cases of screening colonoscopy. Ileal intubation is indicated in certain circumstances such as suspected inflammatory bowel disease and GI bleeding. There is much pathology that can be observed within the ileocecum. Careful and systematic examination should be stressed during GI endoscopic training and practice. In this review, the authors demonstrate its anatomy, endoscopic findings, and pathologies.

Abstract
PURPOSE Appendiceal tumors are rare, but high neoplasm rates have been reported at interval appendectomy after periappendicular abscess. Non-operative management of uncomplicated acute appendicitis has shown promising results. The data on appendiceal tumor incidence and presentation among acute appendicitis patients is limited, especially in patient cohorts differentiating between uncomplicated and complicated acute appendicitis. Objective was to assess appendiceal tumor incidence and tumor association to appendicitis in patients with uncomplicated and complicated acute appendicitis. METHODS This nationwide population-based registry study was conducted from 2007 to 2013. The Finnish Cancer Registry and the National Institute for Health Registry were used to combine data on all appendiceal tumors and acute appendicitis diagnosis with medical reports evaluated at eight study hospitals. RESULTS Altogether, 840 appendiceal tumors were identified, and out of these, 504 patient reports were reviewed, including 472 patients in this study. Tumor was diagnosed at appendectomy for suspected acute appendicitis in 276 patients (58%). In the whole study, histologically acute appendicitis and tumor were both present in 53% (n = 250), and out of these, 41% (n = 102) were complicated and 59% (n = 148) uncomplicated acute appendicitis. The associated tumor risk was significantly higher in complicated acute appendicitis compared with uncomplicated cases (3.24% vs. 0.87%, p < 0.001). Overall tumor prevalence among acute appendicitis patients was 1.24%. CONCLUSIONS Appendiceal tumor prevalence in acute appendicitis was low. Tumor risk was significantly higher in complicated acute appendicitis compared with uncomplicated acute appendicitis. The risk of missed appendiceal tumors related to antibiotic therapy of uncomplicated acute appendicitis is very low.

Abstract
Appendiceal neuroendocrine neoplasms (ANEN) are mostly discovered coincidentally during appendicectomy and usually have a benign clinical course; thus, appendicectomy alone is considered curative. However, in some cases, a malignant potential is suspected, and therefore additional operations such as completion right hemicolectomy are considered. The existing European Neuroendocrine Tumour Society (ENETS) guidelines provide useful data about epidemiology and prognosis, as well as practical recommendations with regards to the risk factors for a more aggressive disease course and the indications for a secondary operation. However, these guidelines are based on heterogeneous and retrospective studies. Therefore, the evidence does not seem to be robust, and there are still unmet needs in terms of accurate epidemiology and overall prognosis, optimal diagnostic and follow-up strategy, as well as identified risk factors that would indicate a more aggressive surgical approach at the beginning and a more intense follow-up. In this review, we are adopting a critical approach of the ENETS guidelines and published series for ANEN, focusing on the above-noted "grey areas".

J Med Case Rep 2018; 12:275. [PMID: 30244681 PMCID: PMC6151924 DOI: 10.1186/s13256-018-1789-6] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2018] [Accepted: 08/01/2018] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Goblet cell carcinoid is a rare but distinct entity of appendiceal tumors which is a hybrid or mixed tumor consisting of both epithelial (glandular) and neuroendocrine elements containing goblet cells. This entity is important to recognize and appropriately grade as it tends to be more aggressive than typical carcinoid tumors, often presenting with metastatic disease. As a result, the 5-year overall survival is 14-22% in stage III-IV disease. GCC therefore warrants more aggressive surgical and medical (chemotherapy) interventions than typical carcinoid tumors. Through this case report we give a brief update on GCC pathological features, staging, surgical management, and review the literature as a guide to indications for chemotherapy and choice of agents. CASE PRESENTATION We present the case of a 77-year-old Caucasian man with a history of stage I adenocarcinoma of transverse colon status post transverse colectomy who was incidentally found on surveillance colonoscopy to have an abnormal appendiceal orifice lesion. A biopsy revealed an appendiceal goblet cell carcinoid and he underwent a right hemicolectomy which revealed a pathologic stage III GCC for which he received eight cycles of adjuvant chemotherapy with capecitabine. CONCLUSIONS It is essential that patients who have tumors > 2 cm, are pT3 or pT4, have higher grade histology with signet ring (Tang grade B or grade C), locally advanced, or with positive surgical margins on appendectomy undergo a right hemicolectomy. Although there is no category 1 evidence, consensus recommendations are that patients with stage II (particularly Tang B and C) and stage III GCC be offered adjuvant chemotherapy with a regimen based on 5-fluorouracil, as these patients are known to have high rates of relapse.

Abstract
Appendiceal neoplasms are identified in 0.9 to 1.4% of appendiceal specimens, and the incidence is increasing. It has long been professed that neuroendocrine tumors (formerly carcinoids) are the most common neoplastic process of the appendix; recent data, however, has suggested a shift in epidemiology. Our intent is to distill the complex into an algorithm, and, in doing so, enable the surgeon to seamlessly maneuver through operative decisions, treatment strategies, and patient counseling. The algorithm for evaluation and treatment is complex, often starts from the nonspecific presenting complaint of appendicitis, and relies heavily on often subtle histopathologic differences.

Cytoreductive Surgery and Normothermic Intraperitoneal Chemotherapy for Signet Ring Cell Appendiceal Adenocarcinoma With Peritoneal Metastases in the Setting of Cirrhosis. Gastroenterology Res 2018; 11:247-251. [PMID: 29915638 PMCID: PMC5997481 DOI: 10.14740/gr1029w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2018] [Accepted: 05/15/2018] [Indexed: 12/15/2022] Open
Abstract
Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are combined to treat peritoneal surface malignancies (PSM). The objective of cytoreduction is to eradicate macroscopic disease, while HIPEC addresses residual microscopic disease. Currently, there are no protocols guiding treatment of cirrhotic patients with PSM. We report the case of a cirrhotic patient with signet ring cell (SRC) appendiceal adenocarcinoma who underwent normothermic, as opposed to hyperthermic intraperitoneal chemotherapy (IPC). A 50-year-old woman with compensated class A cirrhosis and chronic hepatitis B and C underwent a right hemicolectomy in 2007 and adjuvant chemotherapy in 2008 for appendiceal SRC adenocarcinoma. In 2011, she was found to have peritoneal disease after a laparotomy. She subsequently experienced intolerance to chemotherapy, with stable disease on serial restaging. In light of her cirrhosis, the decision was made to perform CRS and IPC without hyperthermia to treat her residual disease. In 2012, she underwent CRS (omentectomy, total abdominal hysterectomy, left salpingo-oophorectomy) and IPC with mitomycin C. Thirty-day postoperative morbidity included delayed abdominal closure (Clavien-Dindo Grade IIIb), prolonged ventilator support (IIIa), vasopressor requirements (II), and confusion (II). The patient’s liver function remained stable. Eight months later, she had evidence of recurrence on computed tomography. Twenty-two months later, she developed an extrinsic compression secondary to evolving disease, requiring a palliative endoscopic stent. The patient expired from her disease 29 months after her CRS and IPC. The criteria guiding selection of suitable candidates for CRS continues to evolve. Concomitant compensated cirrhosis in patients with PSM should not constitute a reason independently to exclude CRS with intraperitoneal chemotherapy, given the oncologic benefits of the procedure.

Abstract
BACKGROUND Goblet cell carcinoids (GCCs) of the appendix are rare mucinous neoplasms, for which optimal therapy is poorly described. We examined prognostic clinical and treatment factors in a population-based cohort. METHODS Patients diagnosed with GCC from 1984 to 2014 were identified from the British Columbia Cancer Agency and the Vancouver Lower Mainland Pathology Archive. RESULTS Of 88 cases with confirmed appendiceal GCCs, clinical data were available in 86 cases (annual population incidence: 0.66/1,000,000). Median age was 54 years (range 25-91) and 42 patients (49%) were male. Metastasis at presentation was the strongest predictor of overall survival (OS), with median OS not reached for stage I-III patients, and measuring 16.2 months [95% confidence interval (CI) 9.1-29] for stage IV patients. In 67 stage I-III patients, 51 (76%) underwent completion hemicolectomy and 9 (17%) received adjuvant 5-fluorouracil-based chemotherapy. No appendicitis at initial presentation and Tang B histology were the only prognostic factors, with inferior 5-year recurrence-free survival (53 vs. 83% with appendicitis, p = 0.02; 45% Tang B vs. 89% Tang A, p < 0.01). Of 19 stage IV patients, 10 (62.5%) received 5-fluorouracil-based chemotherapy and 11 (61%) underwent multiorgan resection (MOR) ± hyperthermic intraperitoneal chemotherapy (HIPEC). Low mitotic rate and MOR ± HIPEC were associated with improved 2-year OS, but only MOR ± HIPEC remained significant on multivariate analysis (hazard ratio 5.4, 95% CI 1.4-20.9; p = 0.015). CONCLUSIONS In this population-based cohort, we demonstrate excellent survival outcomes in stage I-III appendiceal GCCs and clinical appendicitis. Hemicolectomy remains the standard treatment. In metastatic disease, outcomes remain poor, although MOR ± HIPEC may improve survival.

Abstract
Neuroendocrine gastro-entero-pancreatic neoplasms (GEP-NENs) constitute a heterogeneous group of tumors, whose incidence has increased over the years. The most frequent site for primary disease is the stomach followed by small and large intestine, and pancreas. In the last decade, a dramatic growing in the incidence of small, incidental GEP-NENs has been recorded. In parallel, an increasing attitude toward more conservative approaches instead of surgical management has being widely spreading. This is particularly true for small, asymptomatic, pancreatic NEN as for these tumor forms an active surveillance has proven to be safe and feasible. Primary site and biological features of the neoplasms lead to different strategies and indications for surveillance and follow-up. This review focuses on the current evidence on modality and timing of surveillance and conservative treatment of incidentally discovered lesions.

Abstract
Primary signet ring cell carcinoma is a rare event in surgery. It looks like acute appendicitis and it is difficult to diagnose it on clinical grounds alone. The diagnosis is always confirmed by histopathology of a surgically removed appendix. A young man, 22 years old, presented with vomiting, diarrhea, and cramps in his abdomen without abdominal tenderness (mild abdominal discomfort in the right lower abdominal quadrant without signs of peritoneal irritation) during the previous month. The first endoscopic results showed only changes of mucosa that could be attributed to endoscopic and clinical representation of Crohn's disease. A few days after the initiation of the therapy with aminosalicylates and corticosteroids, the patient went into ileus and was transferred to the Department of Surgery, where he underwent an emergency right-sided hemicolectomy with resection of the transversal colon and forming of an ileostoma. The first pathohistological diagnosis was pseudomembranous colitis. Because the patient's condition was deteriorating, a revision of the pathohistological diagnosis was done. After careful revision and extensive sampling, a signet ring cell carcinoma arising in the appendix with infiltration of the ileocecal region was found. Immunohistochemically, tumor cells were positive for CDX-2 CK7, CK20, CK19, and carcinoembryonic antigen and negative for chromogranin A. Sixteen isolated lymph nodes were negative. Although the patient had a disease that was localized to the appendix and ileocecal region with no apparent distal metastasis, his clinical condition was worsening rapidly and he died after 2 months. This case shows the aggressive biological behavior of the appendix signet ring cell carcinoma. Scrupulous histopathological examination of the appendix is an obligatory procedure. Elimination of the signet ring cell carcinoma from other carcinoma subtypes is of special importance as it has an exceptionally poor prognosis and is generally diagnosed in its advanced stages.

Abstract
Goblet cell carcinoid (GCC) is an uncommon tumor of the vermiform appendix. Due to a broad spectrum of morphological differentiation, subclassification and grading of GCCs remains an area of controversy. Two separate systems have proposed classifying GCC tumors into three (classical GCC; adenocarcinoma ex-GCC, signet ring cell type; adenocarcinoma ex-GCC, poorly differentiated carcinoma type) OR two subgroups (low and high grade GCC) based on morphological criteria. We independently compared the inter-observer variability associated with each classification system. Overall, both systems had moderate interobserver agreement, with the two-tiered system (κ=0.54) performing slightly better than the three-tiered system (κ=0.42). GI-specialist pathologists had substantial agreement for both two and three-tiered systems (κ=0.65 vs. 0.65). Non-GI trained pathologists had lower overall agreement than GI trained pathologists, but their agreement was better using the two-tiered system (κ=0.44) than the three-tiered system (κ=0.22). A sub-analysis of 6 cases with a high rate of discordant classification revealed several challenges that exist in applying current criteria, including differentiating "goblet" vs. "signet ring" cell morphology, applying a 1 mm2 criteria to multifocal non-contiguous glandular and single infiltrating cell architecture, differentiating fibro-inflammatory stroma from desmoplastic stroma, and solid architecture in cases with abundant extracellular mucin, and distinguishing "reactive" nuclear atypia from true "cytologic atypia". Despite these challenges, the study identified better agreement among GI pathologists than non-GI trained pathologists. While GI pathologist review may be helpful, further research on objective classification criteria remains an area of interest.

Abstract
PURPOSE The purpose of this study is to investigate the safety and patients' benefit of incidental appendectomy during robot-assisted laparoscopic radical prostatectomy (RALRP). METHODS Fifty-three patients, who had incidental appendectomy during RALRP between January 2012 and March 2014, were enrolled to this study. To evaluate the safety of the procedure, following parameters were evaluated: patient age, duration of surgery, perioperative complications (classified by Clavien-Dindo), time to bowel movement, and length of hospital stay. Furthermore, intraoperative visual appearance, location, and histopathological evaluation of the appendix were evaluated. Data was analyzed by descriptive statistics. RESULTS Mean age of patients was 61 years, the average hospital stay 5 days. No perioperative complications occurred. The appendix was unsuspicious in 39 patients (73.6%); 14 patients (26.4%) had macroscopically signs of inflammation. Of the 53 resected appendixes, the histopathological evaluation showed 33 (62.2%) inconspicuous appendices, 11 (20.8%) post-inflammatory changes, 4 (7.5%) with chronical signs of inflammation and 3 (5.7%) with signs of acute inflammation. In 2 patients (3.8%), low-grade mucinous neoplasms were found in the specimens. CONCLUSIONS Incidental appendectomy during RALRP is a feasible procedure. With regard to inflammation and neoplastic changes, incidental appendectomy can be considered for patients scheduled for robot-assisted prostate surgery.

Abstract
AIM The operative treatment for non-metastatic appendiceal carcinoma is controversial despite the recommendation of right hemicolectomy (RH) by many researchers. The aim of this population-based study was to compare outcomes after RH and less radical resection than right hemicolectomy (LRH). METHOD A total of 1144 patients who underwent resection with additional lymphadenectomy of Stages I-III appendiceal carcinoma from 2004 to 2012 were identified in the Surveillance, Epidemiology and End Results database. Overall survival (OS) and cancer-specific survival (CSS) after RH and LRH were assessed by unadjusted and risk-adjusted Cox regression analysis and by propensity score matched analysis. RESULTS A total of 855 (74.7%) patients underwent RH and 289 (25.3%) underwent LRH. In an unadjusted analysis, survival after LRH and RH did not differ in OS [hazard ratio (HR) 0.95, 95% CI 0.71-1.26, P = 0.707] and CSS (HR 0.95, 95% CI 0.69-1.32, P = 0.762). The 5-year OS and CSS in patients who underwent RH were 71.6% (95% CI 67.8-75.6%) and 76.4% (95% CI 72.8-80.3) compared with 73.8% (95% CI 67.9-80.2) and 78.7% (95% CI 73.2-84.7) in patients with LRH, respectively. No relevant difference in survival between LRH and RH could be observed in a multivariable analysis (OS, HR 0.90, 95% CI 0.65-1.25, P = 0.493; CSS, HR 0.87, 95% CI 0.60-1.26, P = 0.420) and after propensity score adjusted analysis (OS, HR 0.87, 95% CI 0.62-1.22, P = 0.442; CSS, HR 0.97, 95% CI 0.67-1.40, P = 0.883). CONCLUSIONS In this retrospective analysis, survival after RH for non-metastatic appendiceal carcinoma was not statistically significantly superior to LRH. Hence, LRH with lymphadenectomy might be sufficient for treatment of non-metastatic appendiceal carcinoma.

Abstract
INTRODUCTION Mucinous tumors of the appendix are a rare pathology, with a prevalence below 0.5%. Clinical presentation usually occurs during the sixth decade of life, and mucinous tumors can clinically mimic acute appendicitis. The aim of this study is to describe the clinical and demographic variables, therapeutic procedure and diagnosis of these tumors. We analyze the association between mucinous tumors and pseudomyxoma peritonei (PP), as well as the association with colorectal and ovarian tumors. METHODS A retrospective study was performed including patients who underwent an appendectomy between December 2003 and December 2014. RESULTS Seventy-two mucinous tumors of the appendix were identified among 7.717 patients reviewed, resulting in a prevalence of 0.9%. Mean age at presentation was 64 years, 62% patients were female and 38% males. An incidental diagnosis was made in 43% of patients. Mucinous tumors of low malignant potential were significantly related to the presence of pseudomyxoma peritonei, identified in 16 (22%) of the cases. We also observed an increased risk of ovarian mucinous tumors in patients with a diagnosis of appendiceal mucinous neoplasm. In our sample, 22 (30.5%) patients showed a synchronous or metachronous colorectal cancer. CONCLUSIONS Appendiceal mucinous tumors are frequently an incidental finding. The diagnosis of mucinous tumors of low malignant potential is a factor associated with the development of pseudomyxoma peritonei. Histologic tumor grade and the presence of peritoneal dissemination will determine surgical treatment that can vary, from appendectomy to cytoreductive surgery.

Abstract
Goblet cell carcinoid (GCC) is staged and treated as adenocarcinoma (AC) and not as neuroendocrine tumor (NET) or neuroendocrine carcinoma. The term carcinoid may lead to incorrect interpretation as NET. The aim of the study was to explore pitfalls in staging and clinical interpretation of GCC and mixed GCC-AC, and propose strategies to avoid common errors. Diagnostic terminology, staging, and clinical interpretation were evaluated in 58 cases (27 GCCs, 31 mixed GCC-ACs). Opinions were collected from 23 pathologists using a survey. Clinical notes were reviewed to assess the interpretation of pathology diagnoses by oncologists. NET staging was incorrectly used for 25% of GCCs and 5% of mixed GCC-ACs. In the survey, 43% of pathologists incorrectly indicated that NET staging is applicable to GCCs, and 43% incorrectly responded that Ki-67 proliferation index is necessary for GCC grading. Two cases each of GCC and mixed GCC-AC were incorrectly interpreted as neuroendocrine neoplasms by oncologists, and platinum-based therapy was considered for 2 GCC-AC cases because of the mistaken impression of neuroendocrine carcinoma created by use of the World Health Organization 2010 term mixed adenoneuroendocrine carcinoma. The term carcinoid in GCC and use of mixed adenoneuroendocrine carcinoma for mixed GCC-AC lead to errors in staging and treatment. We propose that goblet cell carcinoid should be changed to goblet cell carcinoma, whereas GCC with AC should be referred to as mixed GCC-AC with a comment about the proportion of each component and the histologic subtype of AC. This terminology will facilitate appropriate staging and clinical management, and avoid errors in interpretation.

Abstract
Neuroendocrine tumors (NETs) are originating from neuroendocrine cells in diffuse endocrine systems. NETs are diagnosed by characteristic histologic features and immunoprofiles. Recent 2010 WHO classification for gastroenteropancreatic NETs introduced grading system based on mitotic count and Ki-67 proliferation index. Gastroenteropancreatic NETs are classified as NET grade 1, NET grade 2, and neuroendocrine carcinoma (NET grade 3). However, the carcinoid is still used in classification of NETs of the lung and uterine cervix. Some issues with grading system such as methodologies for evaluation of Ki-67 index and subclassification of neuroendocrine carcinoma (NET grade 3) are arising. The importance of Ki-67 labeling index is emerging in differential diagnosis of lung carcinoids. In this review, we focus on recent grading and classification of NETs and related issues in various organs, including gastrointestinal tract, pancreas, lung, and female reproductive organs.

Abstract
Low-grade appendiceal mucinous neoplasm (LAMN) is rare disease, and the absence of characteristic clinical symptoms makes preoperative diagnosis difficult. The strategy of treatment for LAMN has not been established. Surgical approach and lymph node (LN) dissection are still controversial. We herein present a case of LAMN with difficulties in making the preoperative diagnosis, which exhibited invagination and was treated by laparoscopy-assisted ileocecal resection with LN dissection. When cystic mass is detected in the bowel, LAMN or mucinous adenocarcinoma should be considered as a different diagnosis. And the laparoscopy-assisted ileocecal resection is a feasible operation for LAMN with careful procedure.

Abstract
Introduction Acute appendicitis is significantly common. Despite the increased use of computed tomography, the number of perforated cases has been stable in the past three decades. Between 2% and 6% of patients with acute appendicitis present appendiceal mass, often described as inflammatory phlegmon or abscess. Malignant tumors are confirmed by pathological analysis in 0.9–1.4% of all appendectomies performed to treat acute appendicitis. However, recent series demonstrate an elevated incidence of malignancies, ranging from 5.9 to 12%, in patients with inflammatory appendiceal mass. Methods The analysis was based on a systematic review of the literature. The articles were searched in PubMed for the period from 1987 to 2016. Articles presenting the incidence of the hidden malignancy among patients with appendiceal inflammatory mass were selected. Variables as age, interval appendectomy rate, the incidence of neoplasm, time to surgery, minimally invasive assessment, histology, right colectomy rate and morbidity were analyzed. Results A total of 13.244 patients were described as presenting acute appendicitis. Appendiceal tumor is present in approximately 1% of the appendectomies, while the rate of neoplasm varies from 10 to 29% in patients presenting appendiceal inflammatory mass. Interval appendectomies, despite been the minority of the procedures, disregard the higher morbidity associated with right sided colectomies. The review of literature also describes oncologic, histologic and clinical aspects of patients presenting appendiceal neoplasm, describing the most frequent histologic subtypes of this illness. Conclusion Hidden appendiceal neoplasm in acute appendicitis are rare, fortunately. However, its incidence is much higher in patients presenting appendiceal inflammatory mass. Hence, interval appendectomy should be considered in this subgroup of patients.

Abstract
Appendix is the most common site of occurrence for a goblet cell carcinoid tumor. A diagnosis of an appendiceal goblet cell carcinoid is made in retrospect the majority of the time. These tumors are best treated with a right hemicolectomy and adjuvant therapies tailored according to the presence or absence of residual disease. Presentation as a perforated appendix is seen in 16% of these tumors. The natural history and the ideal management strategy in such a scenario are not well described. In those with peritoneal spread cytoreductive surgery with HIPEC (hyperthermic intraperitoneal chemotherapy) offers the best disease-free and progression-free survival. Close follow-up with cross-sectional imaging helps in identifying recurrences at the earliest. Multimodality management involving patient participation in every aspect of care accomplishes high-value care in the treatment of these tumors.

Abstract
CONTEXT -Gastrointestinal (GI) and pancreatobiliary tracts contain a variety of neuroendocrine cells that constitute a diffuse endocrine system. Neuroendocrine tumors (NETs) from these organs are heterogeneous tumors with diverse clinical behaviors. Recent improvements in the understanding of NETs from the GI and pancreatobiliary tracts have led to more-refined definitions of the clinicopathologic characteristics of these tumors. Under the 2010 World Health Organization classification scheme, NETs are classified as grade (G) 1 NETs, G2 NETs, neuroendocrine carcinomas, and mixed adenoneuroendocrine carcinomas. Histologic grades are dependent on mitotic counts and the Ki-67 labeling index. Several new issues arose after implementation of the 2010 World Health Organization classification scheme, such as issues with well-differentiated NETs with G3 Ki-67 labeling index and the evaluation of mitotic counts and Ki-67 labeling. Hereditary syndromes, including multiple endocrine neoplasia type 1 syndrome, von Hippel-Lindau syndrome, neurofibromatosis 1, and tuberous sclerosis, are related to NETs of the GI and pancreatobiliary tracts. Several prognostic markers of GI and pancreatobiliary tract NETs have been introduced, but many of them require further validation. OBJECTIVE -To understand clinicopathologic characteristics of NETs from the GI and pancreatobiliary tracts. DATA SOURCES -PubMed (US National Library of Medicine) reports were reviewed. CONCLUSIONS -In this review, we briefly summarize recent developments and issues related to NETs of the GI and pancreatobiliary tracts.

Abstract
Malignant neoplasms of the appendix are rare and represent less than 1% of gastrointestinal cancers. Goblet cell carcinoids (GCC) tumors are a distinctive group of heterogeneous appendiceal neoplasm that exhibit unique clinical and pathologic features. This review focuses on the current diagnostic procedures, pathogenesis, possible signaling mechanisms and treatment options for GCC. Perspectives for future research are discussed. The tumor likely arises from pluripotent intestinal epithelial crypt base stem cells. Previous findings of Notch signaling as a tumor suppressor in Neuroendocrine tumors may have a similar role in this tumor too. Loss of Notch signaling may be the driver mutation with other successive downstream mutations likely favors them into progressing and behavior similar to poorly differentiated adenocarcinoma with minimal neuroendocrine differentiation. A multidisciplinary approach is suggested for optimal outcomes. Surgery remains the main treatment modality. Simple appendectomy may be sufficient in early stages while right hemicolectomy is recommended for advanced tumors. Cytoreductive surgery with heated intraperitoneal chemotherapy may improve survival in a select few with metastatic peritoneal disease. These tumors have an unpredictable behavior even in early stages and local recurrence and delayed metastases may be seen. Lifelong surveillance is warranted.

Abstract
A 68-year-old man presented with progressive right lower quadrant abdominal pain and tenderness without rebound tenderness, and with constipation during the prior 9 mo. Abdomino-pelvic computed tomography and magnetic resonance imaging demonstrated a dilated appendix forming a fistula to the sigmoid colon. Open laparotomy revealed a bulky abdominal tumor involving appendix, cecum, and sigmoid, and extending up to adjacent viscera, without ascites or peritoneal implants. The abdominal mass was removed en bloc, including resection of sigmoid colon, cecum (with preservation of ileocecal valve), appendix, right vas deferens, testicular vessels, and minimal amounts of anterior abdominal wall; and shaving off of small parts of the walls of the urinary bladder and small bowel. Gross and microscopic pathologic examination revealed an appendix-to-sigmoid malignant fistula secondary to perforation of mucinous adenocarcinoma of the appendix with minimal local spread (stage T4). However, the surgical margins were clear, all 13 resected lymph nodes were cancer-free, and pseudomyxoma peritonei or peritoneal implants were not present. The patient did well during 1 year of follow-up with no clinical or radiologic evidence of local recurrence, metastases, or pseudomyxoma peritonei despite presenting with extensive stage T4 cancer that was debulked without administering chemotherapy, and despite presenting with malignant appendiceal perforation. This case illustrates the non-aggressive biologic behavior of this low-grade malignancy. The fistula may have prevented free spillage of cancerous cells and consequent distant metastases by containing the appendiceal contents largely within the colon.

Abstract
Background Disseminated peritoneal adenomucinosis (DPAM) patients often have a history of appendectomy with identification of an incidental mucinous neoplasm (low-grade appendiceal mucinous neoplasm (LAMN)). The rate of developing DPAM is not well established. Methods Twenty-two patients with incidental LAMN were identified and monitored with cancer markers and CT every 4–6 months. Laparoscopy with peritoneal washing was performed in patients either in the event of radiographic disease or after 12 months in absence of radiographic disease. The rate of detecting peritoneal metastasis was determined for CT scan and laparoscopy. Results Peritoneal metastasis was detected in 5 (23 %) patients. Occult disease was detected in four patients at laparoscopy without a detectable disease on CT scan. One patient developed radiographic progression at 6 months confirmed with laparoscopy. Four patients were treated with cytoreductive surgery (CRS)/HIPEC and one with CRS only. The 17 patients with negative laparoscopy remain disease free with a median follow-up of 50 months. Conclusions The rate of peritoneal metastasis in incidental LAMN patients was 23 %. Laparoscopy was the primary screening tool identifying occult metastasis. The median PCI of 7 was low, and all the patients underwent R0/R1 resections. This study revealed 1 in every 4.4 patients with LAMN may develop PMP. Longer follow-up and further patient surveillance is warranted.

Abstract
BACKGROUND Right hemicolectomy is indicated for primary appendiceal carcinoids with diameters greater than 2 cm because of an increased risk of metastasis to the lymph nodes of the gut. However, the natural history of positive nodes remains unknown. OBJECTIVE The aim of this study was to investigate the impact of metastatic lymph nodes on survival among patients with pure or mixed primary appendiceal carcinoids, while controlling for potential confounders such as age, sex, tumor size, surgical intervention, and lymph node rate (number of positive lymph nodes/lymph node yield). DESIGN This is a retrospective comparative study.. SETTINGS Data were retrieved from the Surveillance, Epidemiology and End Results database. PATIENTS Patients undergoing colectomy for appendiceal carcinoids between 1998 and 2009 were selected. MAIN OUTCOME MEASURES The survival curves for the 2 groups were compared to evaluate differences in prognosis. Univariate and multivariate analyses were performed. RESULTS Lymph node rates did not significantly differ between the pure and mixed carcinoid groups (p = 0.768), although overall survival was poorer among patients with mixed carcinoids (p = 0.004; HR, 0.498; 95% CI, 0.310-0.800). For pure carcinoids, surgical intervention (p = 0.029; HR, 0.241; 95% CI, 0.067-0.867), age (p < 0.001; HR, 1.083; 95% CI, 1.051-1.116), and lymph node rate (p = 0.039; HR, 5.295; 95% CI, 1.089-25.754) were independent predictors of overall survival. For mixed carcinoids, surgical intervention (p = 0.019; HR, 1.675; 95% CI, 1.088-2.578), tumor size (p < 0.001; HR, 0.442; 95% CI, 0.286-0.683), age (p < 0.001; HR, 1.041; 95% CI, 1.026-1.056), and lymph node rate (p < 0.001; HR, 17.471; 95% CI, 10.047-0.382) were significant prognostic factors. LIMITATIONS The study is limited by its retrospective nature and by the shortcomings of the Surveillance, Epidemiology and End Results database related to the availability and quality of data. CONCLUSION Based on the data retrieved from the Surveillance, Epidemiology and End Results database and adjusted for potential confounding factors, the lymph node rate of metastasis strongly impacts overall survival among patients with pure or mixed carcinoids. Nodal metastasis thus appears to be a reliable clinical hallmark of tumor aggressiveness.

Abstract
BACKGROUND Appendiceal neuroendocrine tumors (aNET) are a common entity in routine medical care, with a rate per appendectomy as high as 0.3-0.9 %. Considering the relatively young age at diagnosis for these patients, exact information about the long-term prognosis of aNET is required. Survival rates vary substantially between 71 and 100 % and are mostly limited to 5 years. This investigation assessed the long-term mortality rates of patients who underwent aNET resections at fifteen hospitals. METHODS Between 1990 and 2003, the 10-year survival rates of 79 patients were analyzed using risk-adjusted Cox proportional hazard regression models adjusted for population-based baseline mortality. Additionally, prognostic factors for the oncologic outcomes were assessed. RESULTS The median follow-up of all patients was 12.1 and 13.7 years for those alive. All patients underwent curative R0 resections. No distant metastases were diagnosed. A total of 31 (39.2 %), 29 (36.7 %), 18 (22.8 %), and 1 (1.3 %) patients had stage I, IIA, IIB, and IIIB aNET, respectively, according to the latest classification by the European Neuroendocrine Tumor Society. The 10-year overall and relative survival rates were 83.6 % (95 % CI 75.5-92.6 %) and 96.7 % (95 % CI 87.5-107 %), respectively. The 10-year relative survival rate after resection of aNET did not differ from the survival of the average national population with the same age and gender (p = 0.947). Second primary malignancies (hazard ratio of death 7.0, 95 % CI 1.6-30.6) were identified as a significant prognosticator for long-term survival. CONCLUSIONS Long-term survival is not significantly depreciated after the curative resection of aNET.

Abstract
Gastrointestinal neuroendocrine neoplasms (GI-NENs) are increasingly being recognised, while appendiceal NENs (aNENs) currently constitute the third most common GI-NEN. Appendiceal NENs are generally considered to follow an indolent course with the majority being localised at diagnosis. Thus, the initial surgical approach is not that of a planned oncological resection. Due to the localised nature of the disease in the majority of cases, subsequent biochemical and radiological assessment are not routinely recommended. Histopathological criteria (size, mesoappendiceal invasion, Ki-67 proliferation index, neuro- and angio-invasion) are mainly used to identify those patients who are also candidates for a right hemicolectomy. Goblet cell carcinoids are a distinct entity and should be treated as adenocarcinomas. Despite the absence of any substantial prospective data regarding optimal management and follow-up, recent consensus statements and guidelines have been published. The purpose of this review is to overview the published studies on the diagnosis and management of appendiceal NENs and to suggest a possible management protocol.

Abstract
BACKGROUND Tumors that show a signet ring or adenocarcinoid histomorphology have been associated with a poor prognosis. This study aimed to analyze the clinicopathologic and prognostic features in patients with peritoneal metastasis from mucinous adenocarcinoma (PMCA), adenocarcinoma with signet ring cell (PMCA-S), or adenocarcinoid (PMCA-A) of the appendix treated with cytoreductive surgery and perioperative intraperitoneal chemotherapy. METHODS Retrospective analysis of a prospectively maintained database for all patients treated for appendiceal adenocarcinoma from 1989 to 2012 was performed. RESULTS The study cohort consisted of 494 patients including 361 patients with PMCA (73.1 %), 80 patients with PMCA-S (16.2 %), and 53 patients with PMCA-A (10.7 %). The patients comprised 273 men (55.3 %) and 221 women (44.7 %) with a mean age at presentation of 50.7 years for the PMCA-S patients, 47.3 years for the PMCA patients, and 47.5 years for the PMCA-A patients (p < 0.03). The 3- and 5-year survival rates were respectively 51 and 38 % for PMCA compared with 30 and 22 % for PMCA-S and 26 and 15 % for PMCA-A. The median survival time was 45.4 months for PMCA compared with 18.9 months for PMCA-S and 26.8 months for PMCA-A (p < 0.000). The groups did not differ significantly in the completeness of cytoreduction achieved, with 53.5 % of the PMCA patients having a CC0/1 compared with 46.2 % of the PMCA-S patients and 41.6 % of the PMCA-A patients (p < 0.20). In the multivariate analysis, the independent predictors of a reduced survival were incompleteness of cytoreduction, histomorphology of PMCA-S or PMCA-A, and distant metastasis. CONCLUSION The findings showed that PMCA-S or PMCA-A histomorphology contributes to the poor prognosis associated with peritoneal metastasis from appendiceal adenocarcinoma. The independent predictors for a poor overall survival included incompleteness of cytoreduction, PMCA-S and PMCA-A histomorphology, and distant metastasis.

Abstract
CONTEXT The prognosis of appendiceal goblet cell carcinoid tumors (GCTs) is believed to be intermediate between appendiceal adenocarcinomas and conventional carcinoid tumors. However, GCTs can have mixed morphologic patterns, with variable amount of adenocarcinoma. OBJECTIVE To evaluate the behavior of GCTs and related entities with variable components of adenocarcinoma. DESIGN We classified 74 cases of appendiceal tumors into 3 groups: group 1, GCTs or GCTs with less than 25% adenocarcinoma; group 2, GCTs with 25% to 50% adenocarcinoma; group 3, GCTs with more than 50% adenocarcinoma; and a comparison group of 68 adenocarcinomas without a GCT component (group 4). Well-differentiated mucinous adenocarcinomas were excluded. Clinicopathologic features and follow-up were obtained from computerized medical records and the US Social Security Death Index. RESULTS Of the 142 tumors studied, 23 tumors (16%) were classified as group 1; 27 (19%) as group 2; 24 (17%) as group 3; and 68 (48%) as group 4. Staging and survival differed significantly among these groups. Among 140 patients (99%) with available staging data, stages II, III, and IV were present in 87%, 4%, and 4% of patients in group 1 patients; 67%, 7%, and 22% of patients in group 2; 29%, 4%, and 67% of patients in group 3; and 19%, 6%, and 75% of patients in group 4, respectively (P = .01). Mean (SD) overall survival was 83.8 (34.6), 60.6 (30.3), 45.6 (39.7), and 33.6 (27.6) months for groups 1, 2, 3, and 4, respectively (P = .01). By multivariate analysis, only stage and tumor category were independent predictors of overall survival. CONCLUSION Our data highlight the importance of subclassifying the proportion of adenocarcinoma in appendiceal tumors with GCT morphology because that finding reflects disease stage and affects survival.

Abstract
Primary adenocarcinoma of the appendix is a rare malignancythat constitutes < 0.5% of all gastrointestinalneoplasms. Moreover, primary signet ring cell carcinomaof the appendix is an exceedingly rare entity. In the present report, we describe a rare case of primary signet ring cell carcinoma of the appendix with ovarian metastasesand unresectable peritoneal dissemination occurring in a 45-year-old female patient. She was clinically misdiagnosed as torsion of ovarian cyst. She underwent appendicectomy and unilateral salpingo-oophorectomy.Histopathology revealed signet ring cell carcinoma and a right hemicolectomy was done. She then received palliative systemic chemotherapy with 12 cycles of oxaliplatin, 5-fluorouracil, and leucovorin (FOLFOX-4). The patient is doing well till today on follow up without progression of disease 10 mo after beginning chemotherapy.

Abstract
Background The incidence of appendiceal cancers continues to rise at a very rapid pace. Although surgery has a central role in the management of appendiceal tumors, literature is lacking regarding the pattern and predictors of surgical treatment for patients with appendiceal cancers. We aimed to describe the surgical treatment for patients with appendiceal cancers, with emphasis on utilization based on histology. Methods Hospitalized patients with appendiceal cancer in the US between 2006 and 2010 were included in the study. The Nationwide Inpatient Sample database maintained by the Agency for Health Care Research and Quality was employed for univariate and multivariate testing to identify factors significantly associated with patient outcome. Results A total of 3,799 patient discharges were identified over the 5-year period covered by the study. Neuroendocrine tumor (NET) was the diagnosis in 291 (7.66%) patients and non-NET in 3,508 (92.34%) patients. The mean age was 56.8 years (± SD 14.6), with female predominance (54.73% vs. 45.27%). NET patients were younger than those with non-NET (50.7 vs. 57.4 years; P < 0.001). NET patients were more commonly treated with appendectomy compared to non-NET (OR: 1.59; 95% CI: 1.23 - 2.07; P < 0.001). Hyperthermic intraperitoneal chemotherapy (HIPEC) was used in 8.5% of all the cases, mostly in non-NET histology (91% vs. 8%). Majority of the patients treated with HIPEC had no co-morbid medical illness (60%), and received care at high volume hospitals located in urban areas. There was a very low incidence of in-hospital mortality (2.5%). Conclusions The described surgical utilization pattern should prompt more research focusing on barriers to appropriate surgical debulking and HIPEC utilization in non-NET appendiceal cancers.

Abstract
INTRODUCTION Mucocoele of the appendix is rarely encountered but consultant general surgical and trainees must be aware of it as a differential diagnosis, due to the nuances associated with its management. We aimed to provide a comprehensive review of the current literature concerning this rare surgical pathology. METHODS Search terms "appendi*", "tumour", "malignancy", "mucino*" and "cystadenoma" were used in combination to identify papers from PubMed. Abstracts and full text were manually reviewed to identify suitable papers. RESULTS Full search results included 311 articles. Review of titles and abstracts led to further full text review of 46 articles. Of these 30 were selected for inclusion based on relevance, adequate sample size and recent publication date. DISCUSSION Mucocoele of the appendix describes dilatation with associated luminal mucin and can result from benign and malignant processes. It contributes 0.2-0.7% of all appendiceal pathologies. The most common presenting symptoms are abdominal pain and a palpable mass in the right iliac fossa. Computed tomography of the abdomen and pelvis is key in facilitating diagnosis, although CEA and CA19-9 also have a role. The major complication of malignant causes of mucocoele is progression to pseudomyxoma peritonei. Treatment is surgical with or without chemotherapy depending on the underlying cause. Prognosis depends on aetiology. CONCLUSION Mucocoele of the appendix is a rare diagnosis. However, given the possibility of neoplastic peritoneal dissemination, it should be considered as a diagnosis, especially in older females with non-specific symptoms similar to appendicitis.

Abstract
PURPOSE Appendiceal cancer is a rare and potentially aggressive malignancy. The objectives of this study were to characterize secular demographic patterns of disease and to determine survival by using a population-based data source. METHODS Using the Surveillance, Epidemiology, and End Results database, we conducted a retrospective cohort analysis of patients treated from 2000-2009. RESULTS We identified 4765 patients with appendiceal cancer. The incidence of appendiceal cancer increased by 54% from 2000 (0.63 per 100,000) to 2009 (0.97 per 100,000 population). Incidence rates increased across all tumor types, stages, age groups, and gender. The most common malignancies were mucinous adenocarcinoma (38%), followed by carcinoids (28%), adenocarcinoma-not otherwise specified (NOS) (27%), and signet ring cell adenocarcinoma (7%). Larger tumor size and older patient age were significantly associated with higher relative odds of distant disease at diagnosis (P < 0.0001). Patient and demographic characteristics were significantly associated with higher relative hazard of death (P < 0.0001). CONCLUSIONS Although appendiceal cancer is rare, the incidence increased significantly in the USA from 2000 to 2009. The cause of this trend is not obvious. We did not observe increases differentially associated with stage, histology, or demographic characteristics. Further investigation is needed to examine factors underlying this increase.

Abstract
Due to the anatomical peculiarity of the appendix, diagnosis of tumors arising from this area can be challenging by clinicoradiologic means. We report a case of a rare primary appendiceal signet ring carcinoma with an uncommon presentation. An 86-year-old woman was admitted to our hospital with subacute epigastric pain. Computed tomography demonstrated bowel wall thickening with fat stranding in the ileocecal region. The leading diagnostic consideration was inflammatory bowel disease. Upon colonoscopy, a swollen, distorted ileocecal valve was identified. The remaining colon was otherwise unremarkable. Extensive biopsy sampling of the ileocecal region and colon was performed. A lymphangitic signet ring carcinoma within the ileocecal region was diagnosed on biopsy; there was no dysplasia or carcinoma of the remaining biopsies. By cytomorphology and immunoprofile, a lymphangitic signet ring carcinoma of appendiceal origin was the primary consideration, further confirmed upon subsequent laparotomy. This case represents an unusual pattern of appendiceal tumor spread with localized, lymphangitic involvement, creating a milieu which closely simulates Crohn’s disease on imaging modalities.
