BACKGROUND The frequency of foreign body retention in the abdominal cavity ranges from 1 in 100 to 1 in 3000 surgeries performed. Worldwide literature describes only a few cases of the migration of misplaced surgical gauze into the colon. CASE REPORTS The first case is a 60-year-old patient following laparoscopic cholecystectomy, who excreted (on his own) a cotton sheet 30 × 65 cm after 26 we...
Primary retroperitoneal transitional cell carcinomas (TCCs) are extremely rare neoplasms for which prognosis is very poor. We present a case that underwent complete remission after radiotherapy and concurrent oral chemotherapy. A 68-year-old woman presented with acute onset of bloody stool. Urgent colonoscopy only detected haemorrhoids. Subsequent abdominal ultrasonography revealed a mass of 7 ...
Endometrial cancer generally has a good prognosis because most cases are diagnosed in stage I. It is possible to identify subgroups of patients with early-stage endometrial cancer with a poor prognosis. Despite a traditional generous use of adjuvant radiotherapy, these patients have five-year overall survival of approximately 80%. In this group there is a need for an effective systemic adjuvant...
BACKGROUND AND OBJECTIVES Because little is known about long-term treatment-related nephrotoxicity, the aim was to determine risk factors for renal impairment long after childhood cancer treatment. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Data from 763 adult childhood cancer survivors (414 men) were obtained during regular visits at the late-effects clinic between 2003 and 2009. Median f...
PURPOSE A multi-centre study to assess the value of combined surgical resection and radiotherapy for the treatment of desmoid tumours. PATIENTS AND METHODS One hundred and ten patients from several European countries qualified for this study. Pathology slides of all patients were reviewed by an independent pathologist. Sixty-eight patients received post-operative radiotherapy and 42 surgery o...
Malignant pheochromocytoma is a rare disease with a high mortality. Surgical removal is usually curative while chemotherapy and radiotherapy are palliative treatments. A case of metastatic malignant pheochromocytoma of the right adrenal gland is presented who had fluctuating blood pressure with episodic headache and raised urinary VMA levels. Thoraco-abdominal resection of the tumour resulted i...
We report on a two-phase test performed to assess the ability of the ultrasound-based B-mode acquisition and targeting (BAT) trans-abdominal system to identify non-dedicated fiducial markers implanted into the prostate gland for subsequent image-guided radiotherapy.Although further investigation is warranted in order to identify the optimal echogenic marker and to define its potential use for i...
We report on a patient who presented with cranial nerve VI bilateral paresis, absence of pharyngeal reflex, dysarthria, right tongue deviation, and right facial paralysis. Imaging studies showed an expansive process in the cranial base with clivus and petrous apex osteolysis. A biopsy confirmed the presence of clear cell adenocarcinoma and suspicion of renal tumor metastases. Abdominal imaging ...
Arterioureteral fistulas (AUF) are serious diseases with increasing incidence. This case report relates the management of AUF in a patient with a history of abdominal oncological surgery, pelvic radiotherapy, and a double J stent in place. The fistula was discovered during a hemorrhagic shock with massive hematuria. The bleeding was controlled by a balloon catheter which led to endovascular tre...
