Abstract
BACKGROUND AND AIMS The management of ampullary adenomas in familial adenomatous polyposis (FAP) is challenging due to multiple adenomas in the duodenum, history of previous major abdominal surgery, and desmoid lesions. In this study, we aim to define the optimum management for ampullary adenomas, particularly in FAP. METHODS This is a retrospective study of all patients with pathology-confirmed ampullary adenomas in M.D. Anderson Cancer Center from 2002 to 2018. Relevant data were extracted, including patient demographics, treatments, outcomes, and adverse events. RESULTS There were 137 patients with ampullary adenomas who underwent 159 procedures; 95 of the 137 patients had FAP and were placed under close observation, 29 underwent endoscopic ampullectomy, 4 underwent surgical ampullectomy, and 31 underwent panreaticoduodenectomy (PD). In the close observation group, 12.6% progressed to advanced adenoma and subsequently underwent resection. There was no ampullary cancer detected in this group. The endoscopic ampullectomy group had a postprocedure adverse event rate of 10.2%. Eleven patients had residual/recurrent disease after endoscopic ampullectomy, 3 of whom needed surgery. Four patients underwent initial surgical ampullectomy and 2 subsequently needed PD. Patients who underwent PD had an adverse event rate of 29%. In this group, there were no cases of residual disease or recurrence. CONCLUSIONS The management of ampullary adenomas in FAP should be carefully considered for the best outcome. Although these patients can be managed by endoscopic ampullectomy, careful surveillance for recurrence should be followed along with prompt management of the recurrence when detected. Although PD provides a definitive treatment, it is limited by the patient's comorbid conditions and high adverse event rates.

Abstract
BACKGROUND Duodenal lesions (DLS) are common in patients with familial adenomatosis polyposis (FAP), and screening for duodenal adenocarcinoma (DA) is currently recommended. Endoscopic treatment of DLS is controversial. AIM To report management and outcomes of endoscopic therapy for DLS in patients with FAP. METHODS The records of patients with FAP who underwent endoscopic surveillance or therapy for DLS over a 15-year period were reviewed. Endoscopic intervention included endoscopic surveillance with biopsies, argon plasma coagulation (APC), endoscopic mucosal resection (EMR), EMR with APC, and ampullectomy. Main outcome measurements were recurrence and histology of DLS after endoscopic therapy, complications of endoscopic therapy, and need for duodenectomy. RESULTS Seventy-one patients with FAP and DLS were identified from our endoscopy database as undergoing upper endoscopy for screening and/or surveillance (1995-2009). Mean follow up was 4.5 years (1-15 years). Seventy of the seventy-one (98.5%) patients had multiple flat DLS. Most of the patients were followed with yearly biopsies. APC was performed in 17 patients and EMR was performed in eight patients; in five of the eight EMR patients, APC was also performed to treat the edges of EMR site. During the follow up, 17/55 (31%) patients had histological progression (HP). HP was seen in 5/16 (31%) patients who underwent APC (one was lost to follow-up) and 12/40 (30%) patients followed with biopsies alone. Recurrence of lesions was noted in all patients. Two patients underwent duodenectomy. None of the patients developed DA during follow up. CONCLUSIONS Endoscopic surveillance with directed endotherapy for DLS in FAP is feasible and safe when diligently performed.

Abstract
Small-bowel tumours are an important cause of morbidity and death in patients with familial adenomatous polyposis. Intensive endoscopic surveillance is now standard in the long-term management of this condition. Thus, lesions occurring throughout the small bowel are increasingly noted by oesophagogastroduodenoscopy and flexible pouchoscopy. Some occur commonly de novo (in stomach, duodenum and ampulla), while others may occur following surgery (polyps of the ileostomy, ileoanal pouch, or small bowel above an anastomosis). These differ widely in incidence, natural history and management. This review provides a regional overview of these lesions, in terms of current research findings and management protocols.

Abstract
Cyclooxygenase-2 (COX-2) is highly expressed in human intraepithelial neoplasia of the breast and takes part in the molecular pathway implicated in progression of breast cancer. Recently, we demonstrated that COX-2 protein is mainly located in plasma membrane of lobular intraepithelial neoplasia (LIN) cells suggesting a localization in caveolae-like structures. The aim of the present study is to establish subcellular locations of COX-2 and its colocalization with caveolin-1 (CAV-1) to caveolae structures in LIN. To establish a relationship between COX-2 and CAV-1, 39 LINs were studied by immunohistochemistry and confocal microscopy analysis. COX-2 and CAV-1 expression was observed respectively in 79.5 and in 94.9% of LIN studied. A positive correlation was found between membrane COX-2 staining pattern and CAV-1 expression, while no correlation was found between cytoplasm COX-2 staining pattern and CAV-1. Confocal analysis showed that COX-2 localized to plasma membrane was strictly associated to CAV-1 suggesting that an amount of COX-2 protein is placed in caveolae-like structures. Our results show that COX-2 is localized within caveolae compartment and colocalized with CAV-1 protein in LIN lesions. Because caveolae are rich in signaling molecules, this COX-2 compartment may play an important role in diverse breast cancer carcinogenesis processes.

Abstract
Aneuploidy has been recognized as a common characteristic of cancer cells for >100 years. Aneuploidy frequently results from errors of the mitotic checkpoint, the major cell cycle control mechanism that acts to prevent chromosome missegregation. The mitotic checkpoint is often compromised in human tumors, although not as a result of germline mutations in genes encoding checkpoint proteins. Less obviously, aneuploidy of whole chromosomes rapidly results from mutations in genes encoding several tumor suppressors and DNA mismatch repair proteins, suggesting cooperation between mechanisms of tumorigenesis that were previously thought to act independently. Cumulatively, the current evidence suggests that aneuploidy promotes tumorigenesis, at least at low frequency, but a definitive test has not yet been reported.

Abstract
The compound 5-(4-methoxyarylimino)-2-N-(3,4-dichlorophenyl)-3-oxo-1,2,4-thiadiazolidine (P(3)-25) is known to possess anti-bacterial, anti-fungal, anti-tubercular, and local anesthetic activities. We studied the anti-tumorigenic activity of P(3)-25 and the role of nuclear transcription factor kappaB (NF-kappaB) in this process. In constitutive NF-kappaB-expressing cells, treatment with P(3)-25 inhibited the expression of NF-kappaB-dependent reporter gene, adhesion molecules, and cyclooxygenase. It downregulated phosphorylation of p65 by inhibiting upstream kinases, such as protein kinase A and casein kinase II, but did not alter NF-kappaB DNA-binding activity. Alone, P(3)-25 induced apoptosis in NF-kappaB-expressing and doxorubicin-resistant breast cancer cells, and in the presence of other chemotherapeutic agents, it potentiated apoptosis. Overall, our results suggest that P(3)-25 exerts antitumorigenic activity by inhibiting phosphorylation of p65, the transcriptionally active subunit of NF-kappaB by inhibiting its upstream kinases, and potentiates apoptosis mediated by chemotherapeutic agents. These results suggest novel approaches for designing of anticancer drugs for combination chemotherapy.
