    To assess the safety and feasibility of administering Low dose radiation therapy (LDRT) in patients with immunotherapy-induced arthritis. Number of patients that experience at least one treatment related Common Terminology Criteria for Adverse Events (CTCAE) grade 4 or 5 side effect.

    3 months post enrollment.

Secondary Outcomes (5)

  • Effectiveness of Radiation in treating immunotherapy-induced arthritis.

    3 months post enrollment.

  • To examine the use of steroids.

    3 months post enrollment.

  • To examine the use of rescue analgesics.

    3 months post enrollment.

  • Effectiveness of Radiation in treating immunotherapy-induced arthritis.

    3 months post enrollment.

  • Effectiveness of Radiation in treating immunotherapy-induced arthritis.

Eligibility Criteria

Age40 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients must have histologically confirmed malignancy that is metastatic or unresectable and for which they are receiving single agent or combination immunotherapy or within the last 6 months.
  • Rheumatologist-established diagnosis of new onset CTCAE grade 2-3 immunotherapy-induced inflammatory arthritis or activated osteoarthritis, involving one or more joints (up to 3) including but not limited to hands, shoulders, elbows, hips, knees and ankles.
  • Age ≥ 40 years.
  • ECOG performance status ≤2 (Karnofsky ≥60%).
  • Patients with ability and willingness to sign consent.

You may not qualify if:

  • Contraindications to radiation treatment, such as pregnancy, breast-feeding women and active collagen-vascular disease.
  • Women of child-bearing potential who have positive urine or serum pregnancy test or refuse to do pregnancy test unless last menstrual cycle was \>1 year prior to consent and/or clear documentation states that the patient is peri- or post-menopausal or there was recent supporting objective evidence of 'no pregnancy' status (e.g. blood or imaging) within 30 days prior to initiation of study treatment.
  • Have not received systemic steroids within the last 3 months for the treatment of immune related adverse events.
  • History of prior autoimmune conditions, or concurrent immune related adverse events requiring systemic immunosuppressants.
  • Estimated life expectancy less than 3 months as assessed by investigators.
  • Any condition at the discretion of investigator that will preclude participation in the study.
  • History of secondary malignancy as assessed by investigators.
  • History of radiation to affected joints as assessed by investigators.
