Clinical benefit. Clinical benefit is defined as a reduction of secretory symptoms or reduction of quantifiable hormones or other biochemical tumor markers where concomitantly there is an absence of radiological evidence for tumor progression. [ Time Frame: monthly for clinical benefit, every two months for tumor progression ]
