In vitro, EGFR inhibition, combined with the BRAF inhibitor vemurafenib, causes synergistic cytotoxicity for BRAFV600E metastatic colorectal cancer (mCRC), further augmented by irinotecan. The safety and efficacy of vemurafenib, irinotecan, and cetuximab in BRAF-mutated malignancies are not defined. In this 3+3 phase I study, patients with BRAFV600E advanced solid cancers received cetuximab and irinotecan with escalating doses of vemurafenib. Nineteen patients (18 with mCRC, 1 with appendiceal cancer) were enrolled...

BACKGROUND: There is little evidence for the use of early postoperative intraperitoneal chemotherapy (EPIC) in patients with low-grade appendiceal mucinous neoplasms (LAMNs) with pseudomyxoma peritonei (PMP). This study aims to assess the outcomes regarding the use of EPIC in a large cohort of patients with LAMNs with PMP uniformly treated by cytoreductive surgery (CRS) and perioperative intraperitoneal chemotherapy (PIC), all of whom received hyperthermic intraperitoneal chemotherapy (HIPEC), and most of whom also received EPIC...

The appropriate therapy for metastatic breast cancer must be selected based on the immunohistochemical phenotype of the cancer. However, biopsy for metastatic lesions is difficult. We herein report a patient with incidental appendicitis caused by a metastatic breast cancer which was successfully treated with effective therapy chosen based on the pathological diagnosis obtained on resection. The patient was a 56-year-old female with right breast cancer and an immunohistochemical status of estrogen receptor (ER) (+), progesterone receptor (PgR) (+), human epidermal growth factor receptor 2 (HER2) (3+), and Ki67 40 %...

BACKGROUND: For a long time peritoneal neoplasms were considered beyond surgical intervention and beyond cure, till the concept of cytoreductive surgery (CRS) and adjuvant hyperthermic intraperitoneal chemotherapy (HIPEC) was introduced. However this surgical intervention is technically demanding and associated with considerable postoperative morbidity. OBJECTIVE: To describe the surgical strategy in resection of critical sites loaded by heavy tumor deposits and to evaluate short and long term results of CRS and HIPEC, in a cohort of Egyptian patients with pseudomyxoma peritonei (PMP) from appendiceal origin...

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...

BACKGROUND: Appendiceal cancer is extremely rare with excellent survival after curative resection. There is a concern for the development of additional cancers in survivors of appendiceal cancer. However, existing data is limited to small anecdotal reports on appendiceal carcinoid only. We aim to investigate the risk of subsequent malignancies in patients with appendiceal carcinoma and correlate the risk according to patient and clinical characteristics. METHODS: We identified 3788 patients with appendiceal cancer from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database between 1992 and 2011...

The epidemiology of metastases in neuroendocrine tumors (NETs) is virtually unknown. The present novel approach took use of two nationwide Swedish registers to assess the distribution of metastatic sites in comparison to adenocarcinoma. 7,334 patients with NET were identified from the Swedish Cancer Registry. Metastatic sites were identified from the National Patient and Cause of Death Registries. Sites of metastasis were investigated depending on the primary site of NET. The metastatic potential of NET was assessed...

Peritoneal disseminations from lung cancer are difficult to detect during the patient's clinical course. Therefore, complications of this condition are unclear. We report a case in which peritoneal dissemination from lung cancer complicated appendicitis. A 74-year-old man with lung cancer who was receiving maintenance therapy presented at our hospital because of abdominal pain. It was the seventh day after the 14th cycle of maintenance therapy with bevacizumab. He was diagnosed with acute appendicitis. The resected appendix showed acute appendicitis complicated by appendiceal metastasis from lung cancer...

BACKGROUND: Outcome of pseudomyxoma peritonei (PMP) after cytoreductive surgery (CRS) and hypertermic intraperitoneal chemotherapy (HIPEC) is heterogeneous even after adjusting for clinico-pathological prognostic variables. The identification of additional prognostic or even predictive biomarkers is an unmet clinical need. PATIENTS AND METHODS: Forty patients with mucinous appendiceal tumors and PMP were clinically eligible and had evaluable tumor samples obtained after CRS and HIPEC...

A new histological classification of neuroendocrine tumors (NETs) was established in WHO 2010. ENET and NCCN proposed treatment algorithms for colorectal NET. Retrospective study of NET of the large intestine (colorectal and appendiceal NET) was performed among institutions allied with the Japanese Society for Cancer of the Colon and Rectum, and 760 neuroendocrine tumors from 2001 to 2011 were re-assessed using WHO 2010 criteria to elucidate the clinicopathological features of NET in the large intestine. Next, the clinicopathological relationship with lymph node metastasis was analyzed to predict lymph node metastasis in locally resected rectal NET...

Appendiceal mucocele (AM) is a rare clinical entity comprising 8% of all appendiceal tumors, and it is seen in 0.2-0.3% of all appendectomy specimens. Apart from sporadic cases, there are no enough published data about the incidence of synchronous appendiceal tumors in patients with colorectal cancer. We describe a very rare case of synchronous occurrence of AM, colon adenocarcinoma, and tubulovillous adenoma of the rectum and review the relevant literature. We conclude that thorough preoperative and perioperative evaluations are mandatory in patients undergoing surgery for colorectal cancer to exclude a synchronous colon or an appendiceal primary tumor...

Appendiceal adenocarcinoma typically presents as an incidentally noted appendiceal mass, or with symptoms of right lower quadrant pain that can mimic appendicitis, but local involvement of adjacent organs is uncommon, particularly as the presenting sign. We report on a case of a primary appendiceal cancer initially diagnosed as a rectal polyp based on its appearance in the rectal lumen. The management of the patient was in keeping with standard practice for a rectal polyp, and the diagnosis of appendiceal adenocarcinoma was made intraoperatively...

BACKGROUND: The impact of histopathologic features on oncologic outcomes for patients with peritoneal metastases from goblet cell carcinoid (GCC) undergoing multimodality therapy, including cytoreductive surgery with hyperthermic intraperitoneal chemoperfusion (CRS-HIPEC), is unknown. METHODS: This study prospectively analyzed 43 patients with GCC undergoing CRS-HIPEC between 2005 and 2013. Pathology slides were re-reviewed to classify GCC into histologic subtypes according to the Tang classification...

INTRODUCTION: Mixed adeno-neuroendocrine carcinoma (MANEC) is a rare pathological diagnosis recently defined by the World Health Organization (WHO) in 2010. Prior to the definition by the WHO, tumors with both adenocarcinoma and neuroendocrine components were given multiple pathological designations making it difficult to characterize the disease. The aim of our study is to better characterize MANEC to better understand its natural history to influence patient care and positively impact outcomes...

The fifth leading cause of cancer-related deaths among women in the United States is ovarian cancer. An estimated 21,980 new cases and 14,270 estimated deaths occurred nationwide in 2014. More than two-thirds of cases of ovarian cancer are diagnosed at stage III or IV when the peritoneal cavity or other organs are affected. Primary appendiceal malignant neoplasms may mimic advanced-stage ovarian cancer and can be misdiagnosed because of its presentation as a palpable adnexal mass. The authors describe a 42-year-old woman who was admitted to the department of obstetrics and gynecology to receive treatment for presumed advanced-stage ovarian cancer...

BACKGROUND: Appendiceal cancer most commonly metastasizes to the peritoneum. Cytoreductive surgery (CRS) with heated intraperitoneal chemotherapy (HIPEC) is the standard of care for appendiceal cancer with peritoneal metastases. Adverse events postoperatively have been associated with reduced survival. We analyzed clinical outcomes, including complications after CRS and HIPEC in patients with appendiceal cancer, in a recent cohort of patients to identify prognostic factors. METHODS: Patients undergoing CRS with HIPEC for appendix cancer with peritoneal metastases between January 2007 and December 2009 were identified...

BACKGROUND: Despite colorectal cancer (CRC) screening and survival rates exceeding national averages in the United States, Kaiser Permanente Southern California (KPSC) aimed to identify system-level improvement opportunities to further reduce mortality from CRC. METHODS: To examine modifiable factors contributing to CRC mortality, a structured hybrid electronic/manual mor- tality review was used to examine 50 randomly selected cases among 524 individuals aged 25-75 years diagnosed with stage II, III, or IV CRC after July 2008 who subsequently died...

BACKGROUND: The value of 5-aminolevulinic acid (ALA) in fluorescence detection of peritoneal metastases and the underlying mechanisms were evaluated in patients with peritoneal surface malignancies. MATERIALS AND METHODS: Oral 5-ALA was administered at a concentration of 20 mg ⁄kg body weight with 50 ml of water 2 hours prior to surgery (n=115). The diagnostic value of 5-ALA based fluorescence production was evaluated following white light inspection during prior to cytoreductive surgery and hyperthermic intraperitoneal chemotherapy...

Optical colonoscopy is the gold standard for colon cancer screening and adenoma detection and is the only screening option that can potentially provide therapeutic interventions and adenoma removal during the same session. When other screening strategies generate positive results, currently colonoscopy is the next step for definitive diagnosis and potentially curative therapy. 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...
