RECRUITINGProgression free survival after pituitary surgery according to the clinicopathological classification (HYPOPRONOS)
Clinical, biochemical et imaging evaluation of a cohort of patient operated in the referral center for pituitary tumor. Identification of recurrence or progression an analysis of the clinicopathological classification. Evaluation of the different therapeutic strategies (med, surgery, chemotherapies, radiation therapy) to prevent recurrence or tumor progression.
Time frame: up to 10 years (postoperatively)
Correlation between percentage of SSTR expression of the pituitary tumor and somatostatine analogs efficacy.
Analysis of the expression of SST receptors in GH, PRL and ACTH secreting pituitary tumors: SSTR expression accessed by immunohistochemistry of the pituitary tumor. Evaluation of the response to somatostatine analogs: somatostatine analogs efficacy evaluated by normalization of hormone hypersecretion in ACTH, GH and PRL secreting pituitary tumor.
Time frame: 2007-2020
Correlation between percentage of MGMT expression of the pituitary tumor and tumor response to temozolomide.
Evaluation of MGMT expression (accessed by immunohistochemistry of the pituitary tumor) and response to temozolomide treatment (evaluated according to RECIST criteria) for patient presenting multirecurrent tumors resistant to conventional treatment.
Time frame: 2007-2020
