Pre-operative Surgical Difficulty Stratification Using Predicted Tumor Perfusion and Consistency
Pituitary adenomas (PAs) are among the most prevalent lesions of the sella turcica, accounting for 10%-25% of all intracranial neoplasms. Pituitary macroadenomas (PMAs) are defined with a maximum diameter of over 1 cm. Tumor characteristics are key factors influencing surgical effectiveness and complications of PMAs, with tumor perfusion and consistency identified as major predictive factors in literature. Conventional sequences provide limited information for predicting the perfusion and consistency of pituitary adenomas. Advanced sequences offer additional insights. However, the efficacy of combining radiomic features from multiparametric sequences, incorporating...

Preop fSRS for Resectable Brain Metastases
The purpose of the study is to determine whether treatment with pre-operative hypofractionated stereotactic radiosurgery followed by surgery will improve time to local failure (TTLF) compared to the current standard of care.

Prognostic's Factors of Head and Neck Paragangliomas Evolution
Cervical paragangliomas (HNPG) are rare tumors (0.6% of head and neck tumors) arising from chromaffin tissue, of cervical paraganglia (PGL). The most common locations are carotid body (60% of cases), jugulo-tympanic region and vagal body. More than 30% are proved to occur in a context of genetic predisposition, more often in young people, and genetic screening is recommended in all patients. Multifocal tumors represent 12% of all HNPG and until 50% of familial forms. Most of HNPG are non-secreting, benign and slow growing tumors, but up to 30% present complications of local growth, and up to 10% can develop distant metastasis that define malignancy since there is no pathological...

Proof of Concept of TBio-4101, Lymphodepleting Chemo, IL-2 for Relapsed/Refractory Melanoma
The purpose of this first in human study is to evaluate the feasibility, safety, and efficacy of administering TBio-4101 (tumor infiltrating lymphocytes [TIL]) after receiving a lymphodepleting chemotherapy regimen and before receiving interleukin-2 (IL-2) in participants with unresectable or metastatic melanoma.

Prospective Assessment of Quality of Life (QOL) in Pediatric Patients Treated With Radiation Therapy for Brain Tumors and Non-central Nervous System (Non-CNS) Malignancies
In recent years, remarkable advances in medical oncology, surgery, and radiology have allowed for increasing cure rates for childhood malignancies. This success has led to an emerging understanding of the kinds of effects that treatments can have on the pediatric population and how such effects can influence pediatric cancer survivor's functioning and quality of life. It has become tremendously important to assess the long-term complications due to therapy in this growing sector of survivors and to tailor our treatments so as to minimize these late effects. The Investigators at MGH are committed to improving the delivery of radiotherapy to our patients and improving the outcome...

Prospective Double Arm Randomized Trial: WBRT Alone and WBRT Plus Silibinin
The occurrence of brain metastases (BMs) is increasing given the availability of a more accurate radiological imaging such as MRI for detecting also small brain lesions and the most effective systemic therapy able to control extracranial disease. Although, the new target therapy and immunotherapy has proven to be effective on brain metastasis too, a subgroup of patients shows prove themselves unresponsive to medical treatment. A further subgroup of patients exhibit diffuse brain disease for the presence of multiple brain lesion (>10 BMs) or leptomeningeal carcinomatosis. Among these patients the most treatment employed is represented by whole brain RT. Since the 1950s,...

Protocol for the Study and Treatment of Participants With Intraocular Retinoblastoma
The primary objective of this protocol is to evaluate the response rate of bilateral disease participants who have at least one eye with advanced intra-ocular retinoblastoma (stratum B) using upfront therapy with chemotherapy delivered directly to the eye. The main biology objective is to improve our understanding of the biology and tumorigenesis (how tumor develops) of retinoblastoma when biology specimens are available. As clinicians, the primary goal of the investigators for children with retinoblastoma is to provide optimal therapy using multiple treatment approaches [chemotherapy (into the vein and directly into membrane of eyeball), cryotherapy (freeze and destroy...

Proton Beam or Intensity-Modulated Radiation Therapy in Preserving Brain Function in Patients With IDH Mutant Grade II or III Glioma
This randomized phase II clinical trial studies the side effects and how well proton beam or intensity-modulated radiation therapy works in preserving brain function in patients with IDH mutant grade II or III glioma. Proton beam radiation therapy uses tiny charged particles to deliver radiation directly to the tumor and may cause less damage to normal tissue. Intensity-modulated or photon beam radiation therapy uses high-energy x-ray beams shaped to treat the tumor and may also cause less damage to normal tissue. It is not yet known if proton beam radiation therapy is more effective than photon-based beam intensity-modulated radiation therapy in treating patients with glioma.

Proton Beam Radiotherapy for Medulloblastoma and Pineoblastoma
There are two types of external radiation treatments (proton beam and photon beam). As part of the participant's treatment, they will receive radiation to the entire central nervous system (CNS); this is known as craniospinal irradiation (CSI). In the past, photon radiation therapy has been used for CSI. In this study we will be examining the effects of proton beam radiation therapy. Studies have suggested that this kind of radiation can cause less damage to normal tissue than photon radiation therapy. The physical characteristics of proton beam radiation let the doctor safely deliver the amount of radiation delivered to the tumor that is normally delivered through...
