While we've learned that radiation alone doesn't help that much in melanoma patients:
Radiation alone, not such a good idea in melanoma!!!
Radiation of lymph node basin: not so helpful if that is all that is done...
We have also learned that radiation COMBINED with immunotherapy can make a real difference!!!
Brain mets in Melanoma - don't wait to add immunotherapy after SRS!
Nivo (Opdivo) with radiation = better for melanoma patients with brain mets
And finally....this link....that contains several more links within: Review of abscopal responses after radiotherapy in melanoma patients
Now there is this:
A Prospective Clinical Trial Combining Radiation Therapy With Systemic Immunotherapy in Metastatic Melanoma. Hiniker, Reddy, Maecker, et al. Int J Radiat Oncol Biol Phys. 2016 Nov 16.
Local radiation therapy (RT)
combined with systemic anti-cytotoxic T-lymphocyte-associated protein-4
immunotherapy may enhance induction of systemic antimelanoma immune responses.
The primary objective of the present trial was to assess the safety and
efficacy of combining ipilimumab with RT in patients with stage IV melanoma.
The secondary objectives included laboratory assessment of induction of
antimelanoma immune responses. In our prospective clinical
trial, 22 patients with stage IV melanoma were treated with palliative RT and
ipilimumab for 4 cycles. RT to 1 to 2 disease sites was initiated within
5 days after starting ipilimumab. Patients had greater or equal to1
nonirradiated metastasis measuring greater or equal to 1.5 cm available for response
assessment. Tumor imaging studies were obtained at baseline, 2 to 4 weeks
after cycle 4 of ipilimumab, and every 3 months until progression.
Laboratory immune response parameters were measured before and during
treatment. Combination therapy was
well-tolerated without unexpected toxicities. Eleven patients (50.0%)
experienced clinical benefit from therapy, including complete and partial
responses and stable disease at median follow-up of 55 weeks. Three
patients (27.3%) achieved an ongoing systemic complete response at a median
follow-up of 55 weeks (range 32-65), and 3 (27.3%) had an initial partial
response for a median of 40 weeks. Analysis of immune response data
suggested a relationship between elevated CD8-activated T-cells and response. This is the second
prospective clinical trial of treatment of metastatic melanoma using the
combination of RT and systemic immunotherapy and the first using this sequence
of therapy. The results from the present trial demonstrate that a subset of
patients may benefit from combination therapy, arguing for continued clinical
investigation of the use of RT combined with immunotherapy, including
programmed cell death 1 inhibitors, which might have the potential to be even
more effective in combination with RT.
We still have folks being told by oncologists that they can't combine SRS and immunotherapy or can't have one after the other "too soon" due to some sort of bad effect. Now, while there may be a few exceptions where that reasoning may apply, it is not where the data is leading us!!! Think Jimmy Carter. Cut out the liver met, zap the brain tumor, start anti-PD1....zip, zap, boom. He's already off meds and latest report says melanoma free!!!
Hang tough ratties! Take reports to your docs as needed!!! Wishing you well. - c
