Brief summary
The study objective is to evaluate the use of Stereotactic Body Radiotherapy (high dose of radiation in a few fractions) to cure primary renal cancer in those patients that are not indicated to surgery (high risk of complications, refusal of the patient). This therapy is already used in clinical setting for many tumors with good tolerance as it is not invasive, does not require anesthesia and hospitalization making it suitable for elderly people and frail patients. However there are not enough information regarding the use of ablative doses for the cure of renal cancer and for this reason this study aims to support the use of Stereotactic Body Radiotherapy as a standard of care for inoperable primary renal tumor. This is an observational study, so it collects data from clinical pratice only and does not request study specific procedures.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| evaluate LC of treated lesions at 1 year | from end of treatment to 1 year | local progression is defined as an enlargement of at least 20% relative and 5 mm absolute increase of sum of diameters of target lesions compared to baseline at least after 6 months from treatment end |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| to assess acute and late toxicity | from start of treatment to 3 years | evaluate the presence of toxicities to treatment according to CTCAE 4.03 |
| To assess kidney function with serum creatinine | from start of treatment to 3 years | evaluating serum creatinine at each follow up visit through blood analysis (mg/dL) |
| Progression Free Survival (PFS) | from end of treatment to 1 year | to asses through standard imaging according to clinical practice - The length of time during and after the treatment of cancer that a patient lives with the disease but it does not get worse |
| metastasis free survival | from end of treatment to 3 years | to asses through standard imaging according to clinical practice - The length of time from the start of treatment for cancer that a patient is still alive and the cancer has not spread to other parts of the body |
| Overall Survival | from end of treatment to 3 years | to asses through standard imaging according to clinical practice - The length of time from the start of cancer treatment during which patients diagnosed with the disease are still alive. |
| To asses Quality of Life | from start of treatment to 3 years | Through QLQ-C30 questionnarie we will evaluate quality of life, patient will answer different questions crossing the number that is more suitable regarding their condition (the patient can respond by crossing a number from 1 to 4, 1 = excellent quality of life, 4 = terrible quality of life) |
| To assess kidney function with estimated glomerular filtration rate | from start of treatment to 3 years | evaluating eGFR at each follow up visit through blood analysis (ml/min) |
