Anti-PD-1 Immunotherapy Combined With Stereotactic Body Radiation Therapy and GM-CSF as Salvage Therapy in a PD-L1-Positive Patient With Refractory Metastatic Thyroid Hurthle Cell Carcinoma: A Case Report and Literature Review.

ABSTRACT: Thyroid Hürthle cell carcinoma, known as thyroid eosinophilic carcinoma, is a rare pathological type of differentiated thyroid cancer (DTC), representing 3-4% of all thyroid cancers. However, given the high risk of invasion and metastasis, thyroid Hürthle cell carcinoma has a relatively poor prognosis. Traditional treatment methods have limited effects on patients with metastatic thyroid cancers. Developing a valuable therapy for advanced thyroid carcinomas is an unfilled need, and immunotherapy could represent another choice for these tumors. We herein reported the case of a patient with recurrent advanced thyroid Hürthle cell cancer and positive programmed death-ligand 1 (PD-L1) expression, who suffered tumor progression after re-surgery, radiotherapy, and targeted therapy. It is encouraging that PD-1 inhibitors in combination with GM-CSF and stereotactic body irradiation (SBRT) on metastatic disease have a significant anti-tumor effect.

Project description:Combination anti-PD-(L)1/CTLA-4 blockade is approved in patients with hepatocellular carcinoma (HCC) in the first-line setting or after sorafenib, but whether this treatment has efficacy after prior anti-PD-(L)1 therapy is unknown. We performed a multicenter retrospective review of patients with advanced HCC treated with ipilimumab plus nivolumab after prior anti-PD-(L)1 therapy, excluding patients with prior anti-CTLA-4 treatment. Of the 32 patients who met our inclusion criteria, prior anti-PD-(L)1 regimens included atezolizumab plus bevacizumab (50%, n = 16), other anti-VEGF plus anti-PD-(L)1 combinations (31%, n = 10), and anti-PD-(L)1 monotherapy (19%, n = 6). The median number of prior systemic therapies was 2 (range, 1-8). The objective response rate with ipilimumab plus nivolumab by RECIST 1.1 was 22% [1 complete response (3%), 6 partial response (19%), 8 stable disease (25%), 16 progressive disease (50%), and 1 not evaluable (NE) (3%)], and objective response was associated with improved progression-free survival and overall survival. Immune-related adverse events were reported in 13 patients (41%), with no new safety signals. This study demonstrates that ipilimumab plus nivolumab has efficacy in patients with HCC who have received prior anti-PD-(L)1 therapy, suggesting that failure to respond to prior PD-(L)1 blockade should not preclude treatment with salvage ipilimumab plus nivolumab. Prospective studies are needed to define the optimal sequence of therapies.SignificanceAnti-PD-(L)1 containing regimens are the preferred first-line treatment for advanced HCC, but whether salvage with PD-(L)1/CTLA-4 blockade is effective in patients who have failed prior anti-PD-(L)1 therapy is unknown. Our study demonstrates that ipilimumab plus nivolumab has clinical activity in patients with advanced HCC previously treated with anti-PD-(L)1 therapy, supporting the continued use of this regimen in the late-line setting after prior anti-PD-(L)1 exposure.

Project description:BackgroundSalvage nivolumab and ipilimumab after prior anti-PD-1/PD-L1 therapy is frequently used off-label for clear cell metastatic renal cell carcinoma (mRCC). However, limited data are available to guide such therapy. We performed a meta-analysis to characterize further the safety and efficacy of salvage nivolumab and ipilimumab.MethodsWe conducted a systematic review in accordance with PRISMA. Studies of salvage nivolumab and ipilimumab in patients with mRCC published in English before June 1, 2021 were included. We also included patients treated at the Ohio State University from 2012 to 2020 through a retrospective chart review. The included studies were further stratified into adaptive and standard groups based on their designs. We calculated objective response rate (ORR) and adverse events (AEs) via pooled data and quantitative synthesis using the Stata metaprop procedure. A conservative random effect model was used to combine values.ResultsA total of 7 studies and 310 patients were included. Salvage nivolumab and ipilimumab had an ORR of 14% (95% CI, 0.09-0.21) and median progression-free survival ranged between 3.7 and 5.5 months. Four out of the seven studies were standard design, whereas the other three studies were adaptive. The ORR was numerically higher in the standard group compared with the adaptive group (21% and 9-10%, respectively). The responses to salvage nivolumab and ipilimumab did not correlate with the initial anti-PD-1/PD-L1 responses (odds ratio = 1.45; p = 0.5). Grade ≥3 AEs occurred in 26% of the patients (95% CI, 0.19-0.33). There were no new safety signals observed in this study.ConclusionSalvage nivolumab and ipilimumab demonstrated moderate antitumor activity and a manageable safety profile in patients with mRCC who had prior anti-PD-1/PD-L1 therapy.Implication for practicePatients with metastatic renal cell carcinoma have limited treatment options after progressive disease on anti-PD-1/PD-L1 therapy. The role of salvage nivolumab and ipilimumab in this patient population is poorly defined. The studies on this highly important and clinically relevant topic are limited by small sample sizes. The results from our meta-analysis suggest that nivolumab and ipilimumab are feasible in the salvage setting with moderate efficacy and acceptable toxicity profile. The response rates differ with different treatment designs. This information will be beneficial to guide clinical decision-making and accurately estimating toxicity.

Project description:PurposeWhole gland cryoablation is a guideline-approved definitive treatment for localized prostate cancer, and is being explored for partial gland ablation. However, there is limited data regarding management of cryoablation failures. Stereotactic body radiation therapy (SBRT) is a well-established method of primary treatment for prostate cancer. Here we review salvage SBRT after cryoablation failures.Methods and materialsA large database of patients treated with definitive SBRT was interrogated to identify those who underwent primary cryoablation. All patients were determined to have progressive disease based on a rising prostate specific antigen and/or postcryoablation biopsy. All patients were treated with SBRT over 5 treatment fractions using a robotic radiosurgical platform. Baseline cryoablation characteristics and pre- and posttreatment Expanded Prostate Cancer Index Composite questionnaires were analyzed. Acute and late toxicity was evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events, version 5.0. Cancer outcomes after salvage SBRT were stratified by disease and treatment characteristics.ResultsA total of 51 patients were identified who underwent cryoablation followed by salvage SBRT. The majority (47%) were found to have intermediate-risk disease at the time of SBRT salvage and most commonly were treated with 3500 cGy in 5 fractions to the prostate and seminal vesicles. Only 1 grade 3+ toxicity was identified. Patient-reported quality of life metrics after SBRT salvage followed prior patterns observed in the de novo SBRT setting. With a median follow-up of 40 months, 76% of the cohort demonstrated disease control. Median time to prostate cancer recurrence was 57.5 months, and recurrence was predominantly seen in patients with underlying high-risk disease.ConclusionsThis is the largest cohort of patients treated with any radiation therapy salvage after cryoablation and the first institution to report SBRT as a modality of salvage. Salvage SBRT after cryoablation results in low rates of high-grade toxicity, acceptable changes in patient-reported quality of life, and durable rates of long-term oncologic control.
