Predictive Clinical Features for Response to Adjuvant Immunotherapy in Stage II,III and IV Resected Melanoma
Surgical excision is the treatment of choice for stage II, III and resectable stage IV melanoma and is curative in most cases. Given the recent success of immunotherapy for the treatment of patients with advanced metastatic melanoma, the use of immunotherapy has been evaluated in the adjuvant setting for patients at high risk of recurrence. In this context, Nivolumab prolonged Recurrence-Free Survival (RFS) while reducing toxicity compared with Ipilimumab in a phase III clinical trial, and was subsequently FDA-approved in December 2017 for adjuvant treatment of locally advanced melanoma with metastatic lymph node involvement after resection of cutaneous lesions. While a fraction of...

Predictive Factors for Survival in Aggressive Meningiomas
The investigators plan to collect clinical and molecular data, including ICH, PCR, NGS and methylome, from patients operated on for grade 2 or grade 3 meningioma. The purpose of the study is to identify reliable and easy-to-assess predictive factors for recurrence and survival after surgery.

Predictive Value of Progastrin Titer at Diagnosis and of Progastrin Kinetics During Treatment in Cancer Patients
Progastrin is a pro-hormone that, in physiological conditions, is maturated in gastrin in G cells of the stomach. The role of the gastrin is to stimulate the secretion of gastric acids during digestion. It is also important for the regulation of cell growth of the gastric mucosal. In a healthy person, progastrin is not detectable in the peripheral blood. However, progastrin is abnormally released in the blood of patients with different cancers (colorectal, gastric, ovarian, breast, cervix uterus, melanoma...) The gene GAST coding for progastrin is a direct target gene of the WNT/ß-catenin oncogenic pathway. The activation of this oncogenic pathway is an early event in cancer...

Predictive Value of Serum and Tissue Molecular Markers and Imaging Features in the Invasiveness and Prognosis of Pituitary Neuroendocrine Tumors
As the clinical manifestations of pituitary neuroendocrine tumors vary greatly, 2.7-15% of them are resistant to conventional treatments such as surgery, drug therapy and radiotherapy, and often relapse or regrow in the early postoperative period, which is invasive and has a poor prognosis. Therefore, it is important to find imaging, histological or serum molecular markers for early prediction of the invasiveness and clinical prognosis of pituitary neuroendocrine tumors. The aim of this study is to observe the changes of biomarkers and imaging features in serum or tissues of pituitary neuroendocrine tumors during the course of disease and treatment, and to explore the biomarkers...

Predictive Value of Soluble CD146 in Glioblastoma Patients
Glioblastoma is the most common malignant primary brain tumor with poor prognosis because of its diffusive and infiltrative nature. The FDA approved the use of the anti-VEGF antibody bevacizumab in recurrent GBM. However, resistance to this anti-angiogenic reagent is frequent and fails to enhance patients' overall survival. The investigators previously identified one novel mechanism responsible for bevacizumab-resistance in CD146-positive glioblastoma (Joshkon et al. Acta Neuropathol Commun, 2022). Now, the investigators objective is to prospectively monitor the soluble CD146 value in plasma from patients treated by bevacizumab for recurrent glioblastoma. The investigators...

Prehabilitation, Rehabilitation and Comprehensive Approach to the Sequelae of Brain Tumors
The goal of the present pilot single-cohort feasibility trial is to investigate the feasibility and understand potential mechanisms of efficacy for Neuromodulation-Induced Cortical Prehabilitation (NICP) in adults with brain tumours and eligible for neurosurgery. The main questions it aims to answer are: - is the intervention feasible, in terms of adherence, retention, safety and patient's satisfaction; - what are the mechanisms of neuroplasticity primed by NICP Participants will undergo a prehabilitation protocol, consisting of daily sessions (total: 10-20 sessions) structured as follows: - Intervention 1: non-invasive neuromodulation (TMS/tDCS). - ...

PreOperative Brain Irradiation in Glioblastoma
PreOperative Brain Irradiation in Glioblastoma (POBIG) is a phase I study that will test the safety and feasibility of a single fraction of preoperative radiotherapy in patients with a new radiological diagnosis of glioblastoma (GBM). After the single fraction of radiotherapy, patients will receive standard treatment. The standard treatment consists of resection of the tumor followed by (chemo)radiation (i.e. radiotherapy +/- daily temozolomide (75mg/m2) for 6 weeks (60Gy/30fr) or for 3 weeks (40Gy/15fr)).

Pre-Operative or Post-Operative Stereotactic Radiosurgery in Treating Patients With Operative Metastatic Brain Tumors
This phase III trial studies the side effects and how well stereotactic radiosurgery (SRS) works before or after surgery in patients with tumors that has spread to the brain or that can be removed by surgery. Stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may cause less damage to normal tissue.

Preoperative Radiosurgery for the Treatment of High Grade Glioma, NeoGlioma Trial
This phase I trial finds out the possible benefits and/or side effects of radiosurgery before surgery (preoperative) in treating patients with high grade glioma. Radiosurgery uses special equipment to position the patient and precisely give a single large dose of radiation to the tumor. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Giving pre-operative radiosurgery may improve the odds of brain tumor control and reduce treatment-related side effects.

Pre-operative SRS or Post-operative SRS in Treating Cancer Patients With Brain Metastases
This phase III trial studies stereotactic radiosurgery (SRS) before surgery to see how well it works compared with SRS after surgery in treating patients with cancer that has spread to the brain (brain metastases). SRS is the delivery of focused, high-dose radiation given in a single session to the tumors, with a minimal dose given to uninvolved areas of the brain.
