Lattice Radiation Therapy: a promising option in metastatic cold tumors, with a bulky primary lesion
نویسندگان
چکیده
Metastatic cold tumors with a large primary site (i.e., >5 cm) represent an open issue as surgery is often excluded and immunotherapy (IT) have reported limited response, because of the immunosuppression present in their microenvironments (cold TME).

The Use of Lattice Radiation Therapy (LRT) in the Treatment of Bulky Tumors: A Case Report of a Large Metastatic Mixed Mullerian Ovarian Tumor.
The objective of this teaching case is to report the excellent results of using lattice radiation therapy (LTR) for the treatment of a large metastasis from ovarian carcinosarcoma. This new technical concept extrapolates the traditional spatially fractionated radiation therapy (GRID) technique to advanced three-dimensional (3D) high-dose radiation therapy using modern instrumentation in radiati...
متن کاملGrid: A location dependent intensity modulated radiotherapy for bulky tumors
Background: An effective method for management of large and bulky malignant tumors. This treatment modality is also known as Specially Fractionated Radiation Therapy (SFRT). In this treatment technique a grid block converted the open radiation field into a series of pencil beams. Dosimetric characteristics of an external beam grid radiation field have been investigated using experimental and Mo...
متن کاملClinical results of stereotactic body frame based fractionated radiation therapy for primary or metastatic thoracic tumors.
The aim of this study was to evaluate the treatment outcomes of stereotactic body radiation therapy for treating primary or metastatic thoracic tumors using a stereotactic body frame. Between January 1998 and February 2004, 101 lesions from 91 patients with thoracic tumors were prospectively reviewed. A dose of 10-12 Gy per fraction was given three to four times over consecutive days to a total...
متن کاملDosimetric evaluation of parallel opposed spatially fractionated radiation therapy of deep-seated bulky tumors.
Application of a single fraction of parallel opposed GRID beams as a means of increasing the efficiency of radiation delivery to deep-seated tumors has been investigated. This evaluation was performed by measurement of dosimetric characteristics of the GRID radiation field in parallel opposed and single beam geometry. The limitations of the parallel opposed technique in terms of field size and ...

Dear Editor, Brucellosis is a zoonotic disease that often presents with fever and malaise, and it is sometimes complicated by unusual involvements such as meningitis, endocarditis and arthritis1. Pacemaker-related infections remain a severe form of complication after implantation, and Brucella spp. are rare agents of pacemaker infections2. A 61-year-old man was admitted to the hospital with rec...
