|
E.2.2 | Secondary objectives of the trial |
1. To evaluate Disease Control Rate with endocrine therapy in patients with 18F-FES SUV > 2. 2. To compare the Disease Control Rate with endocrine therapy observed in patients with 18F-FES SUV > 2 with that of patients with 18F-FES SUV < 2. 3. To evaluate Disease Control Rate, within 24 weeks of treatment. 4. To correlate ER expression in the primary tumor and overall FES-uptake in metastases. 5. To correlate ER expression in metastatic biopsies (when available) and in the primary tumor. 6. To evaluate estrogen-related gene expression by PCR on primary tumors and available metastatic biopsies. 7. To correlate the response rate (according to RECIST 1.1) of individual metastatic lesions with their 18F-FES uptake. |
1. Evaluar la tasa de beneficio clínico con la terapia endocrina en pacientes con 18F-FES SUV ? 2. 2. Comparar la tasa de beneficio clínico con la terapia endocrina observado en pacientes con 18F - FES SUV ? 2 con la de los pacientes con 18F - FES SUV < 2. 3. Evaluar la tasa de beneficio clínico, dentro de las 24 semanas de tratamiento. 4. Correlacionar la expresión de ER en el tumor primario y la absorción de FES en las metástasis. 5. Correlacionar la expresión de ER en las biopsias de metástasis (cuando está disponible) y en el tumor primario. 6. Evaluar la expresión génica relacionada con estrógenos mediante PCR en biopsias de tumores primarios y metastásicos disponibles. 7. correlacionar la tasa de respuesta (según RECIST 1.1) de las lesiones metastásicas individuales con su captación de 18F-FES. |
