Filter by:The purpose of the protocol is to evaluate the efficacy and safety of Lanreotide ATG 120 mg in combination with Temozolomide in subjects with unresectable advanced neuroendocrine tumours of the lung or thymus as Disease Control Rate at 9 months.
Circulating tumour cells (CTCs) are detectable in the blood in around 50% of patients with functioning NeuroEndocrine Tumours (NET) arising in the midgut area (tumours which are secreting hormones and are located in the area in the middle of the digestive system) and their presence usually means that the prognosis for the patient is poor. CTCs have also been shown to be valuable as predictive markers following treatment and there is increasing interest in using CTCs as 'liquid biopsies' that can help to inform treatment decisions. CTC analysis has the benefit of being relatively non- invasive and quick compared with a conventional CT scan and is therefore an attractive method of monitoring the tumour throughout the treatment period. The purpose of this study is to assess the clinical value that enumeration will have in predicting the clinical symptomatic response and progression free survival in patients receiving Somatuline Autogel for functioning midgut NETs over a one year period.
The aim of the study is to identify predictive factors for the response to Lanreotide treatment in Acromegaly as well as in Neuroendocrine Tumours.
The diagnostic work-up of patients suspected of having neuroendocrine tumours (NETs) has traditionally been a challenging issue. The last two decades have been marked by the application to use in the diagnosis of NETs of 3 newly available diagnostic techniques: endoscopic ultrasonography (EUS), multidetector CT (MDCT), and more recently, positron emission tomography using 68Ga-labelled octreotide analogues (PET). In a prospective study conducted at a single referral centre that compared PET with conventional somatostatin receptor scintigraphy and MDCT in diagnosis, staging and follow-up of patients affected by NET, PET detected more primary and secondary lesions than other methods. Recent studies investigated the clinical impact of PET in the management of patients affected by NET, previously studied by MDCT. The investigators recently reported the results of the investigation of 19 patients suspected of having primary pancreatic NET and studied by PET, MDCT and EUS. The investigators preliminary data suggest that PET may be slightly more sensitive than MDCT in detecting small (<2cm) pancreatic lesions; accuracy of PET and EUS is probably similar. No prospective study has yet been devoted to evaluate the accuracy of PET in the diagnosis and staging of primary duodenal-pancreatic NETs. Furthermore, the clinical impact of the adjunct of PET to the traditional protocols of diagnosis and staging of these tumours waits to be thoroughly evaluated. Thus the appropriate place of PET in the diagnostic algorithm of patients suspected of having duodenal-pancreatic NET remains undefined. The main aim of this project is to prospectively compare the accuracy of PET and MDCT in the diagnosis and staging of patients suspected of having duodenal-pancreatic NETs. The investigators hypothesised that PET is superior to MDCT in the diagnosis of these neoplasm (the dimension of the study sample is estimated in order to detect a 10% difference). The impact of PET on management plan of affected patients will also be evaluated. As a secondary endpoint of the study, the investigators will compare EUS, PET and MDCT in the diagnosis of primary duodenal-pancreatic NET. The study is designed as a multicentre, prospective, non-randomised clinical trial. All patients will undergo MDCT, PET and EUS in this fixed order.
To evaluate, in patients with progressive neuroendocrine tumours who are not eligible to be treated with either surgery or chemotherapy at the moment of study inclusion, the efficacy of lanreotide Autogel in tumour growth stabilization.
