Stereotactic Body Radiation Therapy in Treating Patients With Oligometastatic Renal Cell Carcinoma

This is an interventional treatment trial for Malignant Neoplasms of Urinary Tract focused on measuring Malignant neoplasms of urinary tract, Oligometastatic renal cell carcinoma, RCC, Stereotactic Body Radiation Therapy, SBRT, XRT, Radiation therapy Read More

Inclusion Criteria:

• Oligometastatic RCC patients (less than or equal to 5 sites of metastases at the time of study entry).
• Pathologically confirmed diagnosis of RCC of any histology.
• At least one site which in the opinion of the treating radiation oncologist is treatable with SBRT and can be biopsied.
• Be willing and able to undergo biopsy of a lesion planned for SBRT both post treatment and pretreatment. In the event that a lesion amenable to SBRT was biopsied prior to enrollment, this material can be used in lieu of a planned biopsy if the tissue is available for review and ki-67 staining at MD Anderson.

• Be greater than or equal to 18 years of age on the day of signing informed consent.

  • NOTE: Patients may be allowed on this trial without a biopsy if they are deemed medically unfit for biopsy or if the biopsy poses undue risk in the opinion of the treating physician(s).

• Eastern Cooperative Oncology Group (ECOG) performance status 0-2.

  • NOTE: If subject is unable to walk due to paralysis, but is mobile in a wheelchair, subject is considered to be ambulatory for the purpose of assessing their performance status.
• Absolute neutrophil count (ANC) greater than or equal to 1,000 /mcL (within 28 days prior to study enrollment).
• Platelets greater than or equal to 50,000 / mcL (within 28 days prior to study enrollment).
• Hemoglobin greater than or equal to 9 g/dL or greater than or equal to 5.6 mmol/L (within 28 days prior to study enrollment).
• Calculated creatinine clearance greater than or equal to 30 mL/min creatinine clearance (CrCl) using the Cockcroft-Gault formula (within 28 days prior to study enrollment).
• Serum total bilirubin less than or equal to 1.5 mg//dl (except for subjects with Gilbert syndrome, who may have total bilirubin less than 3.0 mg/dl) OR direct bilirubin less than or equal to ULN for subjects with total bilirubin levels greater than 1.5 mg/dl (within 28 days prior to study enrollment).
• Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase [SGPT]) less than or equal to 3 X upper limit of normal ULN OR less than or equal to 5 X ULN for subjects with liver metastases (within 28 days prior to study enrollment).

Exclusion Criteria:

• Receipt of > 1 line of systemic therapy directed towards the metastatic disease. NOTE: Systemic therapy as a component of prior definitive therapy directed towards non-metastatic disease will be allowed. For example, patients receiving adjuvant IL-2 after nephrectomy for an initial M0 diagnosis and who subsequently developed metastatic relapse will be allowed on study. In this instance, there will be no mandatory wash-out period required for enrollment. At trial entry the patient must have received their last dose of systemic therapy e.g. last intravenous (IV) administration or oral (PO tablet/pill) administration 4 weeks prior to initiation of the first dose of radiation.
• Has a diagnosis of active scleroderma, lupus, or other rheumatologic disease which in the opinion of the treating radiation oncologist precludes safe radiation therapy.
• Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial as determined by the treating physician and/or member of the study team.
• Has a metastatic effusion (e.g. pleural effusion or ascites). Note that patients with an effusion that is too small to sample will be eligible for the trial.
• Presence of diffuse metastatic processes including leptomeningeal disease, diffuse bone marrow involvement, and peritoneal carcinomatouses, which by the discretion of the treating physician cannot be treated definitively.

• Is pregnant or expecting to conceive or within the projected duration of the trial at the screening visit.

  • NOTE 1: Female subject of childbearing potential should have a negative urine or serum pregnancy within 28 days prior to study registration up to the first fraction of radiation.
  • NOTE 2: If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
