228 Background: Radium 223 (Ra-223) has been successfully utilised in the trial setting for the treatment of men with metastatic castrate resistant prostate cancer (mCRPC). To date, no real world outcomes from its use in the Irish population have been described. Methods: From September 2016 to March 2019, data from men referred for Ra-223 treatment at our institution was retrospectively collected. We recorded patient characteristics, treatments received and outcomes. Overall Survival (OS) was analysed using the Kaplan-Meier method. Results: 81 men were referred for Ra 223. Complete data was available for 56 men. Median age was 75. 79%(45/56) had over 6 bone metastases and 21%(12/56) had lymph node involvement. The median number of prior systemic treatments for mCRPC was 2. 84%(47/56) of patients were previously treated with Androgen deprivation therapy (ADT); 48%(27/56) Abiraterone, 36%(20/56) Docetaxel, 45%(25/56) Enzalutamide and 9%(5/56) Cabazitaxel. All patients were receiving bone protection agents; 57%(32/56) Zolendronic acid and 43%(24/56) Denosumab. Median ECOG was 1 at the start of treatment and 2 at completion. The median number of treatments received was 4 with 36%(20/56) completing all 6 treatments. The most common toxicity seen was grade1 fatigue occurring in10% (6/56). 17% (10/56) required a blood transfusion during their treatment course. 53%(30/56) required opioid analgesia prior to Ra 223 treatment. 76% of these men (22/30) described improved pain following Rad-223. At a median follow up of 13 months,41%(23/56) were alive. The median OS for the entire group was 7 months. Factors associated with improved OS included ECOG 0-1,fewer than 6 bone metastases, normal alkaline phosphatase level at start of treatment and no prior chemotherapy use. Median OS for those who had not received prior chemotherapy was significantly better than those who had (9 vs 5 months p=0.04). Conclusions: This real world study demonstrates Ra 223 is a well tolerated palliative treatment amongst Irish men with mCRPC. Good performance status, lower alkaline phosphatase, chemotherapy naivety and a low burden of metastatic disease are factors associated with an improved overall survival.

324 Background: Androgen deprivation therapy (ADT) remains a standard of care in the treatment of locally advanced prostate cancer. But thanks to a few key trials (STAMPEDE, CHAARTED, and LATITUDE) reported within the past three years, docetaxel and abiraterone now have roles in extending overall survival in a patient population traditionally treated with ADT alone. These treatments when combined with ADT have been shown to extend overall survival in metastatic hormone-sensitive prostate cancer patients. The role of ADT in relation to other therapies continues to evolve rapidly. We intend to revisit ADT’s longstanding role in prostate cancer treatment using a national cancer database. Our aim is to look beyond traditional standards of care to identify patients more likely to have overall survival benefit from ADT. Are there any subgroups of patients with intermediate or high risk disease that have improved survival outcomes with androgen deprivation therapy, besides patients with localized disease that underwent radiation? Could there be other variables besides PSA and localization of the prostate cancer that should be considered when identifying ADT treatment candidates, or identifying survival trends in these groups? Methods: We are currently analyzing variables present in the National Cancer Database to retrospectively identify predictive factors for overall survival and progression to metastatic castrate resistant prostate cancer in locally advanced prostate cancers treated with ADT. We will evaluate time-to-death from the initiation of ADT and from the diagnosis of metastatic castrate resistant prostate cancer. The following variables in localized, locally advanced, and metastatic prostate cancer will be analyzed with Statistical Analysis Software: age, locally advanced, site-specific metastasis (M1a, M1b, M1c), Gleason score, local treatment (radical prostatectomy or radiation), stage (T, N, and M), prostate lobe (one vs. both; T2a/b vs. T2c), chemotherapy (date, time from M1 stage), comorbidity score, ethnicity, facility type, insurance, and risk groups (low/intermediate/high as per NCCN guidelines).

The Impact

223 Background: Radium 223 (Ra-223) is a FDA and EMA approved alpha particle radiopharmaceutical used to treat men with metastatic castrate resistant prostate cancer (mCRPC) with symptomatic bone metastasis. In view of emerging systemic options, new EMA 2018 licence indication is for 3rd line onwards. We aim to evaluate the impact of systemic therapy sequencing on survival outcomes from a heterogeneous cohort of 228 patients treated with Ra-223 in a single UK centre. Methods: We prospectively collected data from 228 men underwent Ra-223 therapy for mCRPC between April 2014 and August 2018. Survival outcomes in relation to sequence of systemic treatment used prior to Ra-223 were analysed. Results: Medium age = 72 (51-87) years. Most patients (n = 142, 69%) received at least one systemic agent prior to Ra-223: docetaxel and/or cabaxitaxel chemotherapy (n = 60, 29%), abiraterone (n = 62, 30.1%) and enzalutamide (n = 67, 32.5%) in various sequences. No patients received concurrent Ra-223 /systemic treatment other than LHRH analogue. Key findings are summarized in table below. Conclusions: Our data demonstrated better survival trend in patients who received Ra-223 early. Patients who received prior chemotherapy have worse survival compared with those who were chemo-naïve likely due to bone marrow depletion. Ra-223 should not be offered to patients who have already had both cabaxitaxel and docetaxel as their medium survival is too poor to justify a treatment which takes 6 months to complete.[Table: see text]
