BackgroundThe prognosis for patients with advanced epithelial ovarian cancer remains poor despite aggressive surgical resection and platinum-based chemotherapy. More than 60% of patients will develop recurrent disease, principally intraperitoneal, and die within 5 years. The use of whole abdominal irradiation (WAI) as consolidation therapy would appear to be a logical strategy ...

Radiation therapy of abdominal lesions is problematic at best. The proximity of highly critical structures, tumor locations, and necessary margins combine to make prescription dose delivery with conventional 3-dimensional (3D) conformal techniques difficult. Others have tried to overcome these hurdles with newer modalities including intra-operative radiation therapy (IORT), ...
Purpose: Preoperative external-beam radiation therapy (preop RT) in the management of Retroperitoneal Liposarcomas (RPLS) typically involves the delivery of radiation to the entire tumor mass: yet this may not be necessary. The purpose of this study is to evaluate a new strategy of preop RT for RPLS in which the target volume is limited to the contact area between the tumoral mass and the ...
A case of giant lymph node hyperplasia with systemic symptoms resembling chronic infection is described which showed intense gallium uptake and indistinguishable from uptake seen in an abscess. This rare syndrome may mimic an abdominal abscess and should be considered in the differential diagnosis of patients without prior history of ...

BackgroundThe prognosis for patients with advanced FIGO stage III epithelial ovarian cancer remains poor despite the aggressive standard treatment, consisting of maximal cytoreductive surgery and platinum-based chemotherapy. The median time to recurrence is less than 2 years, with a 5-years survival rate of -20-25%. Recurrences of the disease occur mostly intraperitoneally.Ovarian cancer is a ...

The modulation factor of intensity-modulated radiation scattered by aerosol particles is investigated. It is shown that if the optical fields scattered by individual particles interfere at the photodetector, the modulation of the received signal will be preserved. It is shown experimentally that the modulation ...

Chronic abdominal pain syndrome is becoming increasingly important. The main symptom is persistent abdominal pain, which may vary intensely and be associated with constipation and episodes of vomiting, evolving towards sub- or total occlusion of the bowel. A 65-year old man presented with malignant peritoneal mesothelioma, with ...
Necrotizing fasciitis is a grave complication of ascending omphalitis in the neonate, but because it is rare some of the signs are not well documented. Rapidly progressive anterior abdominal wall edema and cellulitis were noted in 16 patients who were clinically diagnosed with necrotizing fasciitis. Fifteen of these patients died soon after emergence of anterior ...

Many authors point to the peritoneum-blood barrier damage factor in the pathogenesis of abdominal sepsis and peritonitis. The study was undertaken to define the types of blood-peritoneal barrier damage, by providing evidence for a differential approach to intensive care. For this, immunochemical permeability markers and the clinical and laboratory criteria ...

Compared with multileaf collimator (MLC)-based intensity-modulated radiotherapy (IMRT) for moving targets, compensator-based IMRT has advantages such as shorter beam-on time, fewer monitor units with potentially decreased secondary carcinogenesis risk, better optimization-to-deliverable dose conversion, and often better dose conformity. Some of the disadvantages include ...
