Abstract
Desmoid fibromatosis (desmoid tumors) is rare tumors. It can occur as intra-abdominal, extraabdominal, or abdominal wall tumor depending on the site. The abdominal wall type is usually sporadic, but few have been associated with familial adenomatous polyposis. They are commonly seen in young females who are pregnant with a history of the previous cesarean section scar or within the 1st year of the last childbirth. There is an association between this tumor, presence of estrogen receptors, and abdominal trauma. We present a 29-year-old Nigerian woman with fungating lower abdominal wall tumor. This tumor is rare, a high index of suspicion will be very important in making the diagnosis.

Abstract
Desmoid tumors are benign but locally aggressive tumors of mesenchymal origin which are poorly circumscribed, infiltrate the surrounding tissue, lack a true capsule and are composed of abundant collagen. History of trauma or surgery to the site of tumor origin is elicited in up to one in four cases and they most commonly develop in the anterior abdominal wall and shoulder girdle but they can arise in any skeletal muscle. The clinical behavior and natural history of desmoid tumors are unpredictable and management is difficult with many issues remaining controversial, mainly regarding early detection, the role, type and timing of surgery and the value of non-operative therapies. We report a case of anterior abdominal wall desmoid tumor in a 40-year-old male with a previous history of surgery.

Abstract
Introduction Desmoid tumors are benign but locally aggressive tumors of mesenchymal origin which are poorly circumscribed, infiltrate the surrounding tissue, lack a true capsule and are composed of abundant collagen. History of trauma to the site of tumor origin is elicited in up to 1 in 4 cases and they most commonly develop in the anterior abdominal wall and shoulder girdle but they can arise in any skeletal muscle. The clinical behavior and natural history of desmoid tumors are unpredictable and management is difficult with many issues remaining controversial, mainly regarding early detection, the role, type and timing of surgery and the value of non-operative therapies. Case presentation We report a case of a 23 year old male referred from a district hospital to a national referral hospital in Kenya, after developing a huge abdominal wall desmoid tumor following laparotomy for a blunt abdominal injury fourteen months earlier. The tumor was successfully excised and the abdominal wall defect reconstructed using a vicryl/prolene mesh and a unilateral groin flap. The patient had a non-eventful recovery and was discharged through radiotherapy clinic. Conclusion Wide margin tumor excision alone is a reasonable option in the management of desmoid tumors.

Abstract
Desmoid tumors are fibroblastic/myofibroblastic neoplasms, which originate from musculo-aponeurotic structures and are classified as deep fibromatoses. Despite their benign histologic appearance and lack of metastatic potential, desmoid tumors may cause aggres?sive local infiltrations and compression of surrounding structures. They are often associated with female gender, familial adenomatous polyposis (FAP) and sporadically may occur at sites of previous trauma, scars or irradiation. Molecular studies have demonstrated that these patients are associated with a bi-allelic APC mutation in the affected tissue. Radical tumor resection with free margins remains the first therapy of choice. In cases with anatomical or technical limitations for a wide excision, radiation therapy represents a proven and effective alternative or supplementary treatment.

Abstract
Desmoid tumor, also known as aggressive fibromatosis or desmoid-type fibromatosis, is a rare monoclonal, fibroblastic proliferation arising in musculoaponeurotic structures. Although histologically benign, desmoids are often locally invasive and associated with a high local recurrence rate after resection. Since it is a heterogeneous disease, in particular regarding clinical presentation, anatomic location and biological behavior, treatment should be individualized to reduce local tumor control failure with concurrently acceptable morbidity and preservation of quality of life. Many issues regarding optimal treatment of desmoids remain controversial. However, wide surgical excision remains the treatment of choice, except when surgery is mutilating and is associated with considerable function loss or major morbidity. Involvement of surgical margins is probably associated with an increased risk of local recurrence. Postoperative radiotherapy results in a significant reduction of the local recurrence rate, but only in the case of involved surgical margins. Radiotherapy for gross disease is considerably effective, but is associated with a relatively high rate of complications, which are usually mild or moderate and radiation dose dependent. Radiotherapy should only be applied where anatomic constraints preclude complete resection and radiotherapy is not too toxic. Risk factors for local tumor control failure include young age, large size, presentation as recurrent disease, limb/girdle or intra-abdominal location, involved surgical margins, omission of radiotherapy, radiation dose less than 50 Gy and insufficient radiation field size. Increased comprehension of the pathogenesis and biological behavior of desmoids resulted in the emerging applicability of systemic therapies and a wait-and-see policy. Systemic treatment may be indicated in patients that have anatomic barriers to effective surgery or radiotherapy. Considering the significant morbidity of surgery and/or radiotherapy for certain locations, especially mutilation and loss of function, and the tumor's natural history, which is often characterized by prolonged periods of stability or even regression, a period of watchful waiting may compose the most appropriate management in selected asymptomatic patients. Attempts to complete eradication of the disease may be worse than the disease itself.

Abstract
PURPOSE Constitutive activation of the Wnt signaling pathway is a hallmark of many cancers and has been associated with familial and sporadic desmoid tumors. The aim of the present study is to assess the therapeutic potential of oncolytic adenoviruses selectively replicating in cells in which the Wnt signaling pathway is active on primary cells from desmoid tumors. EXPERIMENTAL DESIGN Primary cells extracted from familial (n = 3) or sporadic (n = 3) desmoid tumors were cultured short term. Cancer cell survival and viral replication were measured in vitro upon infection with two different oncolytic adenoviruses targeting a constitutive activation of the Wnt signaling pathway. Adenoviral infectivity was also assessed. RESULTS Although cells extracted from one sporadic desmoid tumor responded very well to the oncolytic action of the adenoviruses (<20% of viable cells upon infection at a multiplicity of infection of 10), cells from two tumor samples were totally resistant to the viral action. Cells from the remaining samples showed intermediate sensitivity to the oncolytic viruses. These effects were correlated to the level of infectivity of the cells. Finally, in responder cells, evidences of viral replication was observed. CONCLUSIONS Our experimental data suggest that the response of desmoid tumor cells to oncolytic adenovirus is neither correlated to the type of mutation activating the Wnt signaling pathway nor to the familial or sporadic nature of the tumor. In addition, they highlight the variability of infectivity of individual tumors and predict a great variability in the response to oncolytic adenoviruses.

Abstract
Desmoid tumors are rare, benign, fibromatous lesions that are the result of abnormal proliferation of myofibroblasts. Desmoid tumors can be classified as extra-abdominal and abdominal. Abdominal desmoid tumors are either superficial or intraabdominal. These tumors are associated with a high recurrence rates, even if their microscopic characters indicate a benign disease; their biologic behavior often indicates rather a "malignant" disease, which can cause even the death. Intraabdominal desmoid tumors can engulf surrounding viscera and vessels, thereby greatly complicating their surgical treatment. Management is multidisciplinary. Simple observation is a reasonable management option for asymptomatic patients; spontaneous regression of these tumors may be observed. Complete excision is the treatment of choice for tumors causing symptoms or complications. Surgery should be minimized as much as feasible, while at the same time achieving free margins. Adjuvant therapy should be considered in selected cases; the role of other management options (including gene transfer therapy) is currently under intensive investigation.

Abstract
Desmoid tumours are rare neoplasms of fibroblastic origin which arise with disproportionate frequency in patients with familial adenomatous polyposis (FAP). They are thought to develop in about 10-25% of FAP patients and may be the leading cause of death amongst those who have undergone colectomy. Risk factors include trauma, having a distal germline APC mutation, having a family history of desmoids, and probably oestrogens. In very high-risk individuals there may be a case for delay of colectomy or chemoprophylaxis at the time of surgery. Desmoids are now known to be true neoplasms but with normal telomere length and telomerase activity. FAP-associated tumours seem to carry biallelic APC mutations, one of which lies in the distal part of the gene. Such loss of wild-type APC seems to occur relatively late in tumour development. It is likely that beta-catenin plays an important role in tumourigenesis. FAP-associated desmoids tend to arise in the abdomen or abdominal wall. CT scanning gives the best information on tumour anatomy whilst T2-weighted MRI indicates likely behaviour. Treatment may simply consist of observation. Otherwise, usual first-line therapy is with sulindac with or without an anti-oestrogen. Cytotoxic chemotherapy is an option in unresectable tumours. Surgery is a reasonable first-line treatment in abdominal wall tumours but is risky for intra-abdominal tumours and may necessitate massive small bowel resection. Desmoids are the greatest remaining challenge in the management of FAP and further research into their aetiology needs to be combined with multicentre clinical trials of new treatments in order to improve management of the disease.

Abstract
PURPOSE Familial adenomatous polyposis is a highly penetrant, autosomal dominant disease resulting from a germline mutation of the adenomatous polyposis coli gene. Besides colorectal polyps and cancer, more than 90 percent of familial adenomatous polyposis patients also develop duodenal polyposis with an approximately 5 percent lifetime risk of malignant transformation. Because adenomatous polyposis coli protein has a "gatekeeper role" in the adenoma-carcinoma sequence, replacing its function may reduce polyp formation. We studied the functional outcome of per-oral, liposome-mediated adenomatous polyposis coli gene replacement therapy in a multiple intestinal neoplasia mouse model. METHODS Twenty multiple intestinal neoplasia mice, heterozygous for the human homologue adenomatous polyposis coli gene, were randomly assigned to three groups: no treatment (n = 8); control plasmid containing green fluorescence protein reporter gene (n = 6); and plasmid containing the full-length adenomatous polyposis coli gene (n = 6). For the adenomatous polyposis coli-treated and green fluorescence protein reporter gene-treated groups, each mouse received the appropriate plasmid complexed with liposome, administered twice per week by oral gavage regime. Treatment lasted four weeks and all animals were killed at the end of treatment period with harvesting of intestinal tissue for polyp number estimation. RESULTS There was a statistically significant 25 percent reduction in the total number of polyps in the adenomatous polyposis coli-treated (73.1 +/- 1.4) group compared with untreated control (97.8 +/- 5.3, P < 0.01, Tukey test) and multiple intestinal neoplasia mice treated with control green fluorescence protein gene (103.3 +/- 1.7, P < 0.01, Tukey test). CONCLUSION Adenomatous polyposis coli gene dysfunction underlies tumorigenesis in familial adenomatous polyposis patients and multiple intestinal neoplasia mice. This in vivo study provides evidence to support a novel anti-adenoma strategy using enteral adenomatous polyposis coli gene replacement therapy.

Abstract
The dynamic behaviors of cationic liposome-DNA complexes in inside and outside biomembrane models upon lipofection were investigated using the time-resolved quasi-elastic laser scattering (QELS) method. Inside and outside biomembrane models with similar phospholipid compositions to those in living cells were formed at a tetradecane/phosphate buffered saline (TD/PBS) interface. Cationic liposome-DNA complexes were injected into the buffer subphase, and their adsorption/desorption behaviors at the biomembrane models were monitored through changes in the interfacial tension. We found that the adsorption rate of the complexes increased 2.6 times more in the outside model than in the inside one. The adsorption rate of DNA alone did not show a remarkable difference from one side to the other; however, the adsorption rate of the cationic liposome alone showed a similar tendency to that of the liposome-DNA complex. These results indicated that the difference in lipid composition induced a different dynamic behavior of exogenous biomolecules and that the cationic liposomes played an important role in the faster incorporation of DNA into cells upon lipofection.

Abstract
Hereditary polyposis syndromes show extensive phenotypic and genotypic heterogeneity within and among families, a situation that may hinder diagnosis. In these settings, germline mutation testing may be the sine qua non for diagnosis if such a mutation is identified in a patient or family. We provide examples of phenotypically differing polyposis pedigrees depicting various challenges in hereditary polyposis syndrome diagnosis. Our purpose is to augment physician understanding of phenotypic variation and thus help identify high-risk presymptomatic family members who could benefit from highly targeted surveillance and management strategies. We describe nine familial polyposis pedigrees displaying anecdotal clinical problems that can confound the differential diagnosis. Emphasis was given to a multidisciplinary approach focusing on pathological confirmation with respect to number, histology, and location of polyps in the gastrointestinal tract; a detailed family history of cancer at all anatomic sites; noncancer phenotypic features of hereditary polyposis syndromes; and appropriate molecular genetic testing in concert with genetic counseling. Improved physician understanding of the clinical natural history features, genetic transmission patterns, and appropriate gene testing will help in diagnosis and, ultimately, surveillance and management for the various hereditary polyposis syndromes.

BACKGROUND: Desmoid tumors are slow growing deep fibromatoses with aggressive infiltration of adjacent tissue but without any metastatic potential. CASE PRESENTATION: We report on two female patients with desmoid tumor of the abdominal wall who underwent primary resection. Both patients had a history of an earlier abdominal surgery. Preoperative evaluation included abdominal ultrasound, magnetic resonance imaging and computed tomography. The histology in both cases revealed a desmoid tumor. CONCLUSION: Complete surgical resection is the first line management of this tumor entity.
