Cushing's disease: management outcome in a tertiary care centre.
Cushing's syndrome (CS) can pose a challenge in diagnosis and management. Successful management of CS needs accurate localization of the site of lesion. Present article narrates experience of a single center dealing with large number of patients with CS and highlights difficulties in diagnosis as well as management of Cushing's disease (CD).


METHODS
All patients with CD, where histopathological lesion was documented were studied to evaluate yield from different diagnostic tests. Diagnosis was established by standard 2 days low dose dexamethasone suppression test. Localization of the lesion was achieved with high dose dexamethasone suppression (HDDS) and imaging. Inferior petrosal sinus sampling (IPSS) was used whenever diagnosis was not arrived at with the standard tests.


RESULTS
Out of 100 consecutive patients of CS seen, 69 had CD. HDDS had sensitivity of 70% and specificity of 99% in localizing the lesion. Imaging localized the lesion in 68% of patients. Combination of HDDS and imaging localized the lesion in 90% of patients. IPSS helped to localise the lesion in remaining 10% of patients. Transsphenoidal surgery was carried out in 65/69 patients. Cure rate for microadenoma was 77% and for macroadenoma was 36%. Mortality and morbidity rate was 7% and 7% respectively. 2nd TSS, radiotherapy and bilateral adrenalectomy were the additional modalities used in that order, in patients who were not cured or who had recurrence.


CONCLUSIONS
Management of CS is best carried in a center where a team of experienced endocrinologist and neurosurgeon is available.
