BACKGROUND: Appendiceal cancer is a rare disease, which has proven difficult to study in prospective trials. Cytoreductive surgery with HIPEC is an established therapy for peritoneal dissemination from appendiceal cancer. The optimal chemotherapeutic agent to use in the HIPEC is not clear. Mitomycin has long been the utilized, however our previous phase I experience, and European retrospective studies suggest oxaliplatin as an alternative. Therefore, we initiated a multicenter randomized trial to compare mitomycin to oxaliplatin HIPEC for appendiceal cancer...

The appendix gives rise to goblet cell carcinoids, which represent special carcinomas with distinct biological and histological features. Their genetic background and molecular relationship to colorectal adenocarcinoma is largely unknown. We therefore performed a next-generation sequencing analysis of 25 appendiceal carcinomas including 11 goblet cell carcinoids, 7 adenocarcinomas ex-goblet cell carcinoid, and 7 primary colorectal-type adenocarcinomas, using a modified Colorectal Cancer specific Panel comprising 32 genes linked to colorectal and neuroendocrine tumorigenesis...

Cancer cells aberrantly express mucins to enhance their survival. Relative chemoresistance of appendiceal pseudomyxoma peritonei (PMP) is attributed to abundant extracellular mucin 2 (MUC2) protein production. We hypothesized that simultaneous MUC2 inhibition and apoptosis induction would be effective against mucinous tumors. In vitro studies were conducted using LS174T cells (MUC2-secreting human colorectal cancer cells), PMP explant tissue, and epithelial organoid cultures (colonoids) derived from mucinous appendix cancers...

RATIONALE: Heterotaxy with polysplenia is an extremely rare congenital condition resulting from abnormal arrangement of organs in the abdominal and thoracic cavities during embryologic development. When a malignancy such as pancreatic cancer develops under these conditions, surgical resection becomes particularly complex. This case report demonstrates successful pancreatic cancer resection despite the patient's complicated anatomy. PATIENT CONCERNS: An 82-year-old female presented to our institution with complaints of mild right upper quadrant pain radiating to the mid-epigastric region...

Objective: To describe the surgical technique of a subxiphoid approach to remove cardiophrenic lymph nodes in women with advanced ovarian cancer. Materials and methods: The first step is to dissect and separate the anterior insertions of the diaphragm at the xiphoid appendix. Thus, the parietal peritoneum and the upper fibres of the transversus abdominis muscle are incised. Then, the anteroinferior mediastinum is identified and dissected. Diaphragmatic deinsertion may be extended 5-7 cm laterally to the xiphoid appendix following the inferior costal margin according with the localization of the enlarged lymph nodes...

BACKGROUND: Measurement of cell-free DNA (cfDNA) in plasma - the so called liquid biopsy - is a novel method for early detection of cancer. Necrotic cancer cells release various DNA fragments that can be detected in plasma or serum. The aim of our study was to investigate the concentration of circulating ALU115, LINE79 and LINE297 fragments in plasma from venous and arterial blood of colorectal cancer (CRC) patients before, during and 5 days after surgical intervention. PATIENTS AND METHODS: Thirty patients (16 female, 14 male, median age 56 years), undergoing surgery for colorectal and appendix cancer, and 17 healthy volunteers were included in this study...

BACKGROUND: Goblet cell carcinomas (GCCs) of the appendix are rare and aggressive malignancies with early peritoneal dissemination. The aim of the present article is to describe our experience in the management of GCCs with peritoneal carcinomatosis (PC) through cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) and to determine the impact of multiple clinical characteristics on the prognosis. METHODS: From a prospectively maintained database of patients receiving CRS and HIPEC for peritoneal surface malignancy, the data of 15 patients with GCC and PC were collected...

Osseous metaplasia (OM) is rarely observed in colorectal cancer (incidence < 0.4% in rectal cancer), where it has a non-specific clinical presentation and unknown pathogenesis. Here, we report three cases of colorectal carcinoma with OM and propose a new hypothesis. All three patients (two males and one female) were Chinese and had different sites of colorectal carcinoma with OM: rectum, sigmoid colon, and appendix. The pathologic diagnoses were serrated adenocarcinoma; moderately to poorly differentiated adenocarcinoma with micropapillary carcinoma and cribriform comedo-type adenocarcinoma; and mucinous adenocarcinoma, respectively...

Despite advances in our understanding of appendiceal mucinous neoplasms and their relationship to the pseudomyxoma peritonei syndrome, the classification of mucinous tumors of the appendix is still confusing. This review will provide an update on the various classification systems that have been recently proposed for appendiceal mucinous neoplasia, with a particular emphasis on how to handle and report the histologic findings for these tumors using the newly published Peritoneal Surface Oncology Group International (PSOGI) and American Joint Committee on Cancer (AJCC) eighth edition guidelines...

BACKGROUND: Right hemicolectomy is routinely recommended in patients with histologic findings of high-grade appendix tumors after appendicectomy. Undetected peritoneal disease may be encountered at surgery. In high-grade appendix tumors with disease detected radiologically, complete cytoreduction may not be possible and outcomes poor. For these reasons, we adopted a policy of prophylactic cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. OBJECTIVE: The purpose of this study was to quantify the rates of peritoneal and nodal metastatic disease in patients with high-grade appendix tumors without obvious metastatic disease and to report the long-term outcomes of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in these patients...

INTRODUCTION: Acute appendicitis, one of the commonest surgical diagnoses, is rare and more complex presentation in the elderly. Physicians must consider atypical causes appendicitis in this population, which could affect the management of the patient. PRESENTATION OF CASE: An elderly female presented with a two-day history of lower abdominal pain, associated with low-grade fevers and chills. Studies showed leukocytosis and computed tomography (CT) findings consistent with appendicitis...

The grading and staging of appendiceal mucinous neoplasms is challenging and fraught with terminology problems, but has critical prognostic and therapeutic implications. We utilized a small case series to examine the grading and staging systems of appendiceal mucinous neoplasms and outline the evidence for the new systems proposed in the upcoming 8th edition of the American Joint Committee on Cancer (AJCC) Staging Manual. We reviewed 33 cases of appendiceal mucinous neoplasms with available clinical follow-up data, 6 of which were widely disseminated in the peritoneum...

BACKGROUND: There is an ongoing debate on the use of antibiotics instead of appendectomy for treating appendicitis but diagnostic difficulties and longstanding inflammation might lead to increased incidence of bowel cancer in these patients. The aim of this population-based study was to investigate the incidence of bowel cancer after non-surgical treatment of appendicitis. PATIENTS AND METHODS: Patients diagnosed with appendicitis but lacking the surgical procedure code for appendix removal were retrieved from the Swedish National Inpatient Register 1987-2013...

Necrotising infection of the lower limb is a rare presentation for colorectal malignancy. We report a case of a perforated caecal adenocarcinoma presenting with right leg erythema, pain and swelling in the presence of a right lower lobe lung opacity. Following initial debridement and washout, CT imaging demonstrated a thickened terminal ileum, caecum and appendix, in keeping with primary malignancy. This fed the right-sided lower limb sepsis tracking down from the medial aspect of the psoas muscle to give rise to the multiloculated collection seen in the adductor compartment...
