The impact of ultra-radical surgery in the management of patients with stage IIIC and IV epithelial ovarian, fallopian tube, and peritoneal cancer.

OBJECTIVE: The aim of this study is to estimate the percentage of patients with metastatic ovarian, fallopian tube, and primary peritoneal cancer requiring ultra-radical surgery to achieve cytoreduction to less than 1 cm (optimal) or no macroscopic residual disease (complete). METHODS: Perioperative data were collected prospectively on consecutive patients undergoing elective cytoreductive surgery for metastatic epithelial ovarian, fallopian tube, or primary peritoneal cancer at the Norfolk and Norwich University Hospital, a tertiary referral cancer centre in the United Kingdom from November 2012 to June 2016. RESULTS: Over a 42-month period, 135 consecutive patients underwent cytoreductive surgery for stage IIIC and IV ovarian, fallopian tube, or primary peritoneal cancer. The median age of the patients was 69 years. 47.4% of the patients underwent diaphragmatic peritonectomy and/or resection, 20% underwent splenectomy, 14.1% had excision of disease from porta hepatis and celiac axis, and 5.2% of the patients had gastrectomy. Cytoreduction to no macroscopic visible disease (complete) and to disease with greater tumour diameter of less than 1 cm (optimal) was achieved in 54.1 and 34.1% of the cases, respectively. Without incorporating surgical procedures in the upper abdomen ('ultra-radical'), the combined rate of complete and optimal cytoreduction would be only 33.3%. CONCLUSIONS: Up to 50.4% of the patients in this study required at least one surgical procedure classified as ultra-radical, emphasizing the importance of cytoreductive surgery in the upper abdomen in management of women with stage IIIC and IV ovarian, fallopian tube, and primary peritoneal cancer.

Magnetic resonance imaging changes in the pituitary gland following acute traumatic brain injury.

OBJECTIVE: The objective was to study the anatomical changes in the pituitary gland following acute moderate or severe traumatic brain injury (TBI). DESIGN: Retrospective, observational, case-control study. SETTING: Neurosciences Critical Care Unit of a university hospital. PATIENTS: Forty-one patients with moderate or severe TBI who underwent magnetic resonance imaging (MRI) during the acute phase (less than seven days) of TBI. MRI scans of 43 normal healthy volunteers were used as controls. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patient demographics, Acute Physiology and Chronic Health Evaluation II (APACHE II) score, Injury Severity Score (ISS), post-resuscitation Glasgow Coma Score (GCS), Glasgow Outcome Score (GOS), mean intracranial pressure (ICP), mean cerebral perfusion pressure (CPP), computed tomography (CT) data, pituitary gland volumes and structural lesions in the pituitary on MRI scans. The pituitary glands were significantly enlarged in the TBI group (the median and interquartile range were as follows: cases 672 mm3 (range 601-783 mm3) and controls 552 mm3 (range 445-620 mm3); p value<0.0001). APACHE II, GCS, GOS and ICP were not significantly correlated with the pituitary volume. Twelve of the 41 cases (30%) demonstrated focal changes in the pituitary gland (haemorrhage/haemorrhagic infarction (n=5), swollen gland with bulging superior margin (n=5), heterogeneous signal intensities in the anterior lobe (n=2) and partial transection of the infundibular stalk (n=1). CONCLUSIONS: Acute TBI is associated with pituitary gland enlargement with specific lesions, which are seen in approximately 30% of patients. MRI of the pituitary may provide useful information about the mechanisms involved in post-traumatic hypopituitarism.
