Laparoscopic adrenalectomy is beneficial in many patients with subclinical Cushing syndrome because it reduces arterial blood pressure, body weight, and fasting glucose levels. Prospective randomized studies are needed to compare laparoscopic adrenalectomy with a conservative approach and to confirm these results.

The considerable differences in the frequencies of the two subtypes of ampullary tumours reported in literature reinforce the necessity to define molecular markers to distinguish them. Until then, the significance of the histological subtype as a prognostic factor should be evaluated cautiously. Future research on the pathogenesis of ampullary cancer will possibly suggest that we should stop treating this type of cancer as a separate entity.

AbSTrAcTclinically inapparent adrenal masses which are incidentally detected have become a common problem in everyday practice. Approximately 5-20% of adrenal incidentalomas present subclinical cortisol hypersecretion which is characterized by subtle alterations of the hypothalamicpituitary-adrenal axis due to adrenal autonomy. This disorder has been described as subclinical cushing's syndrome, since there is no typical clinical phenotype. The diagnosis of subclinical cushing's syndrome is based on biochemical evaluation; however, there is still no consensus for the biochemical diagnostic criteria. An abnormal 1mg dexamethasone suppression test (DST) as initial screening test in combination with at least one other abnormal test of the hypothalamic-pituitary-adrenal axis has been advocated by most experts for the diagnosis of subclinical cushing's syndrome. DST is the main method of establishing the diagnosis, while there is inhomogeneity of the information that other tests provide. Arterial hypertension, diabetes mellitus type 2 or impaired glucose tolerance, central obesity, osteoporosis/vertebral fractures and dyslipidemia are considered as detrimental effects of chronic subtle cortisol excess, although there is no proven causal relationship between subclinical cortisol hypersecretion and these morbidities. Therapeutic strategies include careful observation along with medical treatment of morbidities potentially related to subtle cortisol hypersecretion versus laparoscopic adrenalectomy. The optimal management of patients with subclinical cushing's syndrome is not yet defined. The conservative approach is appropriate for the majority of these patients; however, the duration of follow-up and the frequency of periodical evaluation still remain open issues. Surgical resection may be beneficial for patients with hypertension, diabetes mellitus type 2 or abnormal glucose tolerance and obesity.

Background: The aim of this study was to analyse retrospectively the long-term results of patients who were operated for adenocarcinoma of the pancreatic head and identify significant prognostic factors. Methods: Eighty patients who were surgically treated for adenocarcinoma of the pancreatic head between 1995 and 2006 met the inclusion criteria and were subject to retrospective analysis. Possible prognostic factors were evaluated and independent predictors of survival were determined. Results: A classic Whipple procedure was performed in 47 patients and a pyloruspreserving pancreatoduodenectomy in 32 patients; one patient underwent total pancreatectomy. Five-year survival rate in this group of patients was 13.6%. Median survival time was 24 months. Univariable analysis demonstrated stage of disease, tumour size and grade and nodal status as significant predictive factors of survival. Multivariable analysis indicated tumour size, nodal status and disease stage as significant prognostic indicators in terms of survival. Conclusions: Long-term survival in pancreatic cancer is still very low. Prognostic factors include differentiation of the tumour, disease stage and nodal status. So far, there has been no reliable method that can accurately predict which patient will mostly benefit from surgical resection. This means that pancreatic cancer resection should nearly always be attempted.
