Description of intervention(s) / exposure
To prospectively describe the proportion of advanced cancer patients being treated with immunotherapy who remain progression free at six months after local treatment of up to five sites of oligoprogressive disease. 33 participants will be recruited across 6 regional Victorian sites over a 2-year period. All participants will be followed until death or study completion, which will be when the last participant has had a minimum of 2 years follow-up. Overall, the study is expected to run for 4 years.
Participants will be observed for any adverse events associated with their local treatment, and will be followed through their standard appointments and re-staging to assess for disease progression.
Participants will have no additional appointments, investigations or testing, apart from those required as part of standard of care treatments. Participants will not have to complete any questionnaires or diaries. Therefore, apart from additional time required for consent and initial enrolment, participants will have no additional study-specific requirements. All data will come from the routine reviews and re-staging which will occur approximately every 3 months from enrolment to end of study (ie a minimum of 2 years and up to 4 years of follow-up).

Outcomes
Primary outcome [1] 334954 0
Landmark progression-free survival, defined as from the time of completion of local therapy to progression. Progression will be inclusive of:
a) Further local therapy requirement
b) Change in systemic treatment for radiological or clinical progression
c) Active cessation of treatment to transition to best supportive care
d) Death
Tests and investigations will include standard re-staging imaging such as CT and MRI, and standard blood tests including tumour markers to assess for radiological and clinical response/progression.
Timepoint [1] 334954 0
The primary endpoint is to assess the proportion of patients who remain progression-free at 6 months from local therapy. Progression-free survival will be continue to be assessed at 12 weekly intervals, until study end at 4 years, as part of describing the change to treatment as per the secondary outcomes. Analysis performed at end of study.
Secondary outcome [1] 422531 0
Time to change in treatment or active decision for best supportive care. This is defined from the date of completion of local therapy to the date of change in treatment (includes further local therapy, change in systemic treatment, decision for best supportive care)
Timepoint [1] 422531 0
Data collected from review of medical records (for example, clinic notes, investigation reports, blood test results) every 12 weeks, until study end at 4 years. Analysis performed at end of study.
Secondary outcome [2] 422532 0
Overall survival, defined from date of completion of local therapy to the date of death from any cause.
Timepoint [2] 422532 0
Data collected from review of medical records (for example, clinic notes, investigation reports, blood test results) every 12 weeks, until study end at 4 years. Analysis performed at end of study.
Secondary outcome [3] 422533 0
To describe local treatment-related serious adverse events using the NCI Common Terminology for Adverse Events v5.0.
Timepoint [3] 422533 0
Data collected from review of medical records (for example, clinic notes, investigation reports, blood test results) every 12 weeks, until study end at 4 years. Analysis performed at end of study.

Eligibility
Key inclusion criteria
1. Patients with histologically proven advanced cancer receiving immunotherapy. Advanced cancer will include any unresectable locally advance or metastatic cancer, primary tumour agnostic. Accepted tumour types will include melanoma, lung cancer, renal cell carcinoma, urothelial cancer, head and neck cancers, and deficient MMR cancer of any primary.
2. On systemic immunotherapy, either alone or in combination the chemotherapy or another systemic treatment.
3. Must have evidence of extracranial metastatic disease with or without intracranial metastases.
4. Clinically or radiologically stable or responding disease to immunotherapy for a period of at least 12 weeks prior to study entry with ongoing clinical benefit as deemed by treating clinician.
5. Evidence of isolated progression in 1-5 lesions amenable to local treatment.
6. Planned local treatment to sites of oligoprogression which can include surgery and/or radiotherapy.
7. Baseline staging either via CT or PET/CT needs to be obtained within 4 weeks of commencement of local therapy. An MRI brain will be required for local therapy of oligoprogressive brain metastases

Statistical methods / analysis
The proportion of patients who remain progression free at 6 months will be compared using the exact binomial probability test against a null hypothesis of 10%. It was considered on clinical grounds that a local treatment strategy would not be worthwhile in this patient population if 10% or less would remain progression free at 6 months.
