Annals of Oncology Conclusions: We report the largest analysis of treatment with N beyond progression in a real world cohort of mRCC supporting that pseudo-progression is a rare event (4%). We show also that treatment beyond progression is very common (49%) and that LDH>200 might be the better ready-to-use predictive factor of a lack of CB.

To date there are limited data on safety profile of combined SBRT and NIVO in mRCC. We report for the first time the toxicities occurred in phase II NIVES Study. Methods: This is a phase II, single arm, multicentre study in pts with mRCC with progression disease after2 prior anti-angiogenic therapies and with measurable non-brain metastatic sites, at least one of which potentially suitable for SBRT. The pts included received hypofractionated radiation in one lesion at dose of 10 Gy/3 fractions after 7 days from the first infusion of NIVO. NIVO will be given as flat dose of 240 mg on day 1 every 14 days for 6 months, then switch to 480 mg q4-weekly in responding pts until PD or unacceptable toxicity. Descriptive statistics are reported for patient/tumor/treatment characteristics and observed severe Adverse Events (AEs) graded by CTCAE v. 4.03. Results: Sixty-nine pts were enrolled from July 2017 to March 2019 in 11 Italian centers. 79.7% of pts had clear cell histology, median age was 67 years (range 43-85), 82.6% were male. ECOG PS was 0 in 57 pts (82.6%), only 18.8% pts had received 2 previous lines of therapy. The most frequent sites of SBRT were lung (39.4% of pts), lymphonodes (16.7%) and bone (10.6%). Toxicities of grade (G) 3-4 related to NIVO were experienced in 13 pts (18.8%); all G3-4 toxicities were outside of the irradiated area. The most frequently observed G3-4 treatment-related AEs included diarrhea (5.8%), fatigue (4.3%), anemia (2.9%) and increase of amylase/lipase (2.9%). To date no G3-4 pneumonitis were observed. Six pts (8.7%) were hospitalized due to treatment-related SAEs. Overall, 5 of 69 treated pts (7.2%) discontinued therapy because of G3-4 AEs. At the time of this analysis 32/69 pts (46%) are still on treatment. Conclusions: Concurrent NIVO plus SBRT is generally well tolerated, without increased rates of common severe toxicity. Definitive data of toxicities and efficacy of the combination of immunotherapy and radiotherapy are not yet mature. Clinical trial identification: NCT03469713.

Background: In the UK renal cancer has an incidence of around 12600 cases per year. Nivolumab is an anti-PD1 checkpoint inhibitor, which was approved in the UK for second or subsequent line treatment of advanced renal cancer in 2016. The aim of this study was to evaluate a regional experience of nivolumab use in this setting. Methods: A retrospective analysis was undertaken of patients who commenced nivolumab as monotherapy for advanced renal cancer at three Cancer Centres in South Central England between February 2016 and April 2019. Information was collated from electronic patient records and e-prescribing systems. Information was gathered on patient demographics, Heng (IMDC) prognostic scores, previous treatments, treatment toxicity, use of steroids and radiotherapy during treatment, physician assessment of response and survival data. Results: 109 eligible patients were identified. The average age was 59 with 72.5% of patients male. 67.9% (74/109) of patients had prior nephrectomy and 50.5% (55/109) had metastatic disease at diagnosis. 82.6% (90/109) had pure clear cell histology. 63.3% (69/109) received nivolumab as second-line treatment, 27.5% (30/109) as third-line treatment and 9.2% (10/109) as fourth-line and beyond. At the start of treatment 19.41% (19/103) had a ‘favourable’ risk Heng score, 61.2% (64/103) had an ‘intermediate’ risk and 18.3% (19/103) had a ‘poor’ risk. The number of Nivolumab cycles received ranged from 1-69, with a mean of 11 and median of 5. 45.9% of patients experienced toxicity of any grade, with 16.5% experiencing grade 3/4 toxicity. 24.8% (28/ 109) received radiotherapy and 40.4% (44/109) received steroids during nivolumab treatment. At response assessment 31.5% showed a response to nivolumab, 9.3% had stable disease and 59.3% had disease progression. From the start of nivolumab treatment median progression-free survival was 5.4 months, and the 12-month overall survival rate was 56.88%. 22.6% (24/109) are still receiving nivolumab. Conclusions: This review has given us important real-world data on the safety and efficacy of nivolumab which reflects the findings of the pivotal phase 3 trials that led to it’s use. Further analysis will allow us to see the effect of different factors on these outcomes. Legal entity responsible for the study: The authors. Funding: Has not received any funding.

D. Anderson Cancer Center, Houston, TX, USA, 12Genitourinary Medical Oncology, MD Anderson Cancer Center, Houston, TX, USA Background: Cryo is an effective intervention for palliation and local control for small primary and metastatic tumours in mRCC. Pre-clinical murine tumour modeling found cryo recruits effector immune cells and synergizes with anti-cytotoxic T lymphocyte antigen 4 (CTLA-4) to inhibit tumour rechallenge as compared to either therapy (tx) alone, leading to a prospective pilot study evaluating safety/tolerability.
