SBRT-LATTICE-PATHY
Recruiting now · Phase 2
Conditions studied: Cancer (Advanced Stage), Cancer (Solid Tumors), Tumor
In brief
To assess the importance of using SBRT-LATTICE-PATHY for the radiotherapy treatment of large tumors that would be considered intractable by currently used standard techniques. In this present study, the investigators will have the possibility of combining SBRT and LATTICE techniques, incorporating the concept of hypoxic tissue irradiation, which are potential modulators of abscopal and bystander effects, performing partial punctual treatment in the vertex region, without the need for irradiation of the entire tissue volume, further improving safety in relation to possible toxicities.

You may qualify if…
- age =or> 18 years;
- Eastern Cooperative Oncology Group (ECOG) performance status < 2; benign and malignant tumors for which the use of radiotherapy is well established in the literature;
- tumors =or> 340 cm³ or with a largest diameter =or> 7 cm;
- no indication for any other type of treatment due to lack of proven clinical benefit (surgery, chemotherapy, standard radiotherapy, immunotherapy, targeted therapy, etc.);
- Palliative Prognostic Index (PPI) =or< 2;
- metastatic disease in the central nervous system (CNS), if present, controlled (up to 3 metastases, each up to 1 cm);
- up to 5 extracranial distant metastases (nodal or extranodal) =or< 5 cm; signed Informed Consent Form (ICF).
You may not qualify if…
- cases in which tumor volume and/or the patient's clinical condition make adequate immobilization/simulation impossible;
- previous local radiotherapy;
- pregnant patients;
- autoimmune diseases;
- genetic instability syndromes;
- ongoing systemic therapy;
