Brief Summary

Systemic therapy is the main treatment for patients with metastatic cancers. Oligo-progression has become a recognized entity for metastatic cancer and it is thought that a subset of cancer cells may ...

Eligibility Criteria

Inclusion

  • Adult patients ≥18 years accrued at the Princess Margaret Cancer Centre
  • 5 or less sites of intra or extra-cranial oligo-progressive, de novo oligo-metastatic, induced oligo-metastatic and repeat oligo-metastatic breast disease amenable to ablative treatment (including but not limited to radiotherapy, surgery, radio-frequency ablation);
  • o at least one lesion should be planned for SBRT
  • OR 5 or less sites of intra or extra-cranial oligo-progressive prostate, bladder and renal cell carcinomas
  • Tumor mass amenable to SABR (≤6cm in size)
  • Confirmation of diagnosis:
  • Known/documented prior histological (for all excluding HCC) or radiological diagnosis (for HCC) of:
  • Pathologically confirmed breast cancer OR,
  • Pathologically confirmed GU cancer (such as prostate cancer, bladder cancer, or radiologically or pathologically confirmed RCC).
  • For prostate patients only: Known metastatic disease treated with ADT (patients who received other ST as first line treatment of mCSPC would be eligible; eg Docetaxel, Abiraterone…)
  • For prostate patients only: Known metastatic CRPC progressing on ST (Docetaxel, Abiraterone, Enzalutamide…)
  • For oligo-progressive disease: receiving any form of ST for at least 3 months with (ST breaks are permitted):
  • Radiographic evidence of ≤3 intra or extra-cranial lesions progressing (including nodal or distant). At least one lesion is suitable for SBRT. Each progressing lesion should fulfill at least 1 of the 3 following criteria for oligo-progression:
  • Progression of a metastasis according to RECIST 1.1 criteria7
  • Unambiguous development of a new lesion from the time of scan taken prior to starting ST
  • Progressive enlargement of a known metastasis on 2 consecutive imaging (CT or MRI) 2-3 months apart, while on ST, with a minimum 5 mm increase in size from baseline.
  • Remainder of metastatic disease stable or regressing, as per RECIST v1.1, evidenced by \>2 consecutive images within the past 4-6 months.
  • Able to provide written consent
  • ECOG performance status 0-3

Exclusion

  • ≥6 progressive metastases
  • Evidence of spinal cord compression or acute event requiring urgent/emergency radiotherapy
  • Prior radiotherapy, with fields overlapping, resulting in excessive doses to organs at risk
  • Previous radical RT in the area of OP
  • Inability to safely treat all sites of progressing metastases
  • Patient cannot tolerate physical set-up required for SBRT
  • Treatment plan respecting normal tissue tolerances using dose fractionation specified within the protocol cannot be achieved
  • Active bowel obstruction, if treating abdominal/pelvic site
  • Neuroendocrine, lymphoma, myeloma or germ cell malignancies
  • Familial syndromes: Von Hippel-Lindau disease, Polycystic Kidney Disease, Hereditary Papillary RCC or Tuberous Sclerosis
