Phase II Trial Evaluating Olaparib Maintenance in Patients with Metastatic Castration-Resistant Prostate Cancer Responsive or Stabilized on Docetaxel Treatment: SOGUG-IMANOL Study. Cancers (Basel) 2023; 15:5223. [PMID: 37958398 PMCID: PMC10649956 DOI: 10.3390/cancers15215223] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Revised: 10/24/2023] [Accepted: 10/27/2023] [Indexed: 11/15/2023] Open
Abstract
The SOGUG-IMANOL trial was a phase 2, uncontrolled, Spanish multicenter study to assess the effect of maintenance treatment with olaparib on radiographic progression-free survival (PFS) in patients with metastatic castration-resistant prostate cancer (mCRPC) who achieved partial or complete response or disease stabilization on docetaxel treatment and had a documented germline/somatic mutation in any of the homologous recombination repair (HRR) genes. Patients received olaparib 300 mg orally twice daily. From the screened population (n = 134), 26 (19.4%) somatic mutations were found, and 14 patients were included in the study. The median radiographic PFS was 11.1 (95%CI, 5.7 to 16.5) months. The median PSA-PFS was 3.5 (95%CI, 1.0 to 6.0) months, and the median clinical PFS was 14.7 (95%CI, 1.8 to 27.5 months). Clinical benefit was observed in 12 patients (85.7%, 95%CI 67.4% to 100%), including two patients with partial response and 10 with stable disease. Six patients reported grade 3-5 adverse events: asthenia (n = 3), anemia (n = 2) and neutropenia (n = 1). In this setting, olaparib has been shown to be an efficacious maintenance treatment in terms of radiographic PFS and clinical benefit, becoming a therapeutic option for some patients harboring an HRR gene mutation and in scenarios where further investigation is needed.

Abstract
168 Background: Prostate cancer is the second most common cancer in men. A number of important systemic therapies have been developed to treat mCRPC and now comprise the current therapeutic landscape. Docetaxel became the first systemic therapy to improve survival in these men in a randomized study demonstrating superiority versus mitoxantrone (18.9 months versus 16.5, p=0,004). But, inexorably, after stopping, disease progresses. Methods: A prospective phase II trial was designed to test Olaparib maintenance efficacy, in terms of progression free survival (PFS), in patients with mCRPC with DNA-repair defects that have achieved partial or complete response after being treated with systemic therapy (at least six cycles of docetaxel). Results: 134 mCRPC patients were included since Feb-2018 to Nov-2020 and were tested for DDR alterations. 19.4% of patients had somatic mutations (30.8% BRCA2, 3.8% BRCA1, 19.2% ATM, 7.7% CHEK2, 7.7% PALB2). 53,8% received Olaparib maintenance treatment, with a median follow-up of 23.3 months. Median age was 73 years. Median basal PSA was 17 ng/dL. 100% were metastatic (14.3% de novo and 85.7% relapsed after primary treatment), 78.6% had bone metastasis, 35.7% visceral and 35.7% adenopathies. 42.9% had previous treatment with abiraterone and 35.7% with enzalutamide. 46.2% received at least 8 cycles of docetaxel. 7.1% achieved a partial response and 92.9% a disease stabilization. Response to Olaparib treatment was 14.3% partial response, 71.4% stabilization and 7.1% disease progression.14.3% had a PSA50 decrease. Median duration of response was 8.27 months. Median PFS was 10.1 months. Median PSA-PFS was 3.5 months. G3/4 adverse events were 21.4% asthenia,14.3% anemia and 7.1% neutropenia. Conclusions: Olaparib maintenance after at least six cycles of docetaxel shows promising activity in mCRPC with DDR alterations, with an acceptable toxicity profile. Our pathogenic mutations percentage (19,4%) is in line with previous publications. Clinical trial information: NCT03434158 .

Abstract
96 Background: Radium-223 represents an option for symptomatic metastatic castration-resistant prostate cancer (mCRPC) after demonstrated an overall survival improvement in the ALSYMPCA trial. Radium-223 real-life experiences are scarce, particularly after the results of the ERA-223 trial. To describe Radium-223 outcomes in real life practice, and specifically those related with bone health, sequence of treatment, and prognostic factors. Methods: Multicenter retrospective study of a cohort of 143 patients with mCRPC treated with Radium-223 in either the second line or third line of therapy or beyond in the context of routine clinical practice between 11 March 2013 and 26 July 2022, in seven Galician hospitals. Survival estimates were calculated by the Kaplan-Meier method, and groups were compared with the log-rank test. The Cox proportional hazards regression model was used to evaluate factors independently associated with OS. Between March 11, 2013, and July 26, 2022, 143 patients were enrolled from 5 Galician hospitals. With a median follow-up of 9.68 months. All patients signed an informed consent form agreeing to participate in this observational study, that was approved by the Galician Ethics Committee, registration code 2018/282. Results: Baseline patient and disease characteristics are summarized. Median follow-up was 9.68 months. Median overall survival (OS) was 12 months (95% CI 9.7 – 16.0). Best OS outcomes were achieved in second and third line, 18 months (95% CI 12.0 – 26.0) and 9.4 months (95% CI 8.0 – 12.0) months, respectively. Among those baseline clinic-analytical factors analyzed, only alkaline phosphatase level >354 UI/L was correlated with a worse OS (HR 2.56 (95% CI 1.39 – 4.72; p=0.003) and the number of cycles of Radium-223 received (HR 0.63 (95% CI 0.54 – 0.73; p<0.001) were prognostic factors for Radium-223. Importantly, ninety-nine of patients (80%) were treated with bone-targeted therapy for bone metastases with no OS differences (p=0.66). Conclusions: In our study, Radium-223 efficacy was consistent with previously reported. Best efficacy was achieved in the second or third line of therapy, independently of docetaxel use. Patients with high baseline alkaline phosphatase had worse OS. Few patients presented skeletal-related events, which could be explained by an adequate use of bone-targeted therapy (zoledronic acid or denosumab). [Table: see text]

Use of multikinase inhibitors/lenvatinib concomitant with radioiodine for the treatment of radioiodine refractory differentiated thyroid cancer. Cancer Med 2022; 11 Suppl 1:47-53. [PMID: 36202606 PMCID: PMC9537052 DOI: 10.1002/cam4.5105] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Revised: 07/14/2022] [Accepted: 07/24/2022] [Indexed: 12/05/2022] Open
Abstract
Thyroid cancer is the most frequent endocrine tumor. However, in locally advanced or metastatic disease we have only two types of treatment at our disposal: radioactive iodine (RAI) when the disease is RAI-sensitive and multikinase inhibitors (MKIs), lenvatinib and sorafenib, when the disease becomes RAI-refractory (RR). This review revisits the published data on the potential combination of MKIs/lenvatinib with RAI in RR-differentiated thyroid cancer and evaluates some special situations where this combination may be of particular interest. The combination of MKIs/lenvatinib with RAI could, at least hypothetically, improve the efficacy seen in both treatments alone via a synergistic effect and with a lower rate of toxicity rates. Early preclinical data support this notion, while its generalized use awaits the results of ongoing clinical trials.

Abstract
LBA4503 Background: New drug combinations are required in advanced clear cell renal cancer (RCC). These potentially include MET inhibition with savolitinib (S) or CTLA-4 inhibition with tremelimumab (T). In this study these agents were given alone or in combination with the PD-L1 inhibitor durvalumab (D). Methods: A multinational open-label randomised phase II study assigning patients to one of D, S, DT or DS was performed. Patients with RCC, who had previously received VEGF targeted therapy but not immune checkpoint inhibitors or MET inhibitors were included. Confirmed response rate (cRR) was the primary endpoint. A response rate of at least 50% was required for further exploration. The S arm was closed early due to a lack of efficacy. DNA alterations were measured using Foundation One and PD-L1 analysis was performed with SP263. This abstract details the pre-planned 12-month interim analyses after the cohort completed randomisation. Results: Between 2017 and 2021, 139 patients were randomised (D N=39, S N=22, DT N=39, DS N=39). The median age was 62 years (range: 28 – 85). cRRs for the 4 arms were D=10%, S=5%, DT=28%, DS=13%, which did not meet the primary objective. cRRs in the MET-driven patients (N=17) were D=0% (0/7), S=0% (0/2), DT=50% (1/2), DS=17% (1/6). cRRs in PD-L1+ves for DT and D were 14% (1/7) and 33% (2/6) respectively. 12-month progression-free survival (PFS) rates were D=26% (80% confidence interval [CI]: 17% - 36%), S=21% (80% CI: 10% - 35%), DT=33% (80% CI: 24% - 43%), DS=17% (80% CI: 10% - 26%). Median overall survival for D=26.1 (80% CI: 16.2 – 32.0) months, S=23.1 (80% CI: 20.6 – 29.7) months, DT=21.9 (80% CI: 16.3 – 31.5) months, DS=16.1 (80% CI: 10.3 – 18.8) months. There was 1 treatment related death in the DT arm. Of the 136 patients who received treatment, grade 3 or more treatment related adverse events occurred in D=10% (4/39), S=26% (5/19), DT=23% (9/39), DS=23% (9/39). Conclusions: This randomised phase II study did not demonstrate significant efficacy for S alone or in combination with D in RCC. The addition of T to D did not demonstrate clearly superior efficacy to D in this setting. Clinical trial information: NCT02819596.

Abstract
BACKGROUND Adjuvant treatment for both small-cell and non-small-cell lung cancer is a controversial topic. There are no published results from prospective studies that either confirm or reject the benefit of adjuvant radiotherapy, although the presentation of recent studies at a number of conferences questions whether there should be a change in the paradigm of adjuvant RT for lung cancer. AIM The main goal of this study is to review the most relevant publications on the topic, updating the state of the matter regarding adjuvant radiotherapy following lung surgery, and analyzing the role of chemotherapy in the process. RELEVANCE FOR PATIENTS This review aims to assess the potential benefit of PORT in NSCLC and SCLC patients by looking at recent research. In doing so, it will be possible to determine which patients might benefit from it as adjuvant treatment after pulmonary resection.

Abstract
364 Background: PRRT with 177Lu-Dotatate (Lutathera) is a radiolabeled somatostatin analog indicated treatment of somatostatin receptor (STTR) positive GEP-NETs. The study aims to establish the efficacy and safety of PRRT in GEP-NETs in a real-world setting. Methods: We conducted an observational, retrospective, multicentric study of 40 patients with GEP-NET treated with PRRT belonging to GGNET (Galician Research Group on Neuroendocrine Tumors) network at Nuclear Medicine Department of Santiago de Compostela University Hospital (Spain). Patients characteristics, overall survival (OS), progression-free survival (PFS), overall response rate (ORR) and toxicity data were retrospectively collected and analyzed. Results: Data from 40 patients (pts) treated between 2016 and 2020 were recorded in this study. Median age was 63.5 years (range 41-85) and 55% were male. The baseline ECOG PS 0/1/2 was 15 (37.5%)/16 (40%)/9 (22.5%). Tumor location was intestinal 26 pts (65%), pancreas in 11 pts (27.5%) and unknown origin in 3 pts (7.5%). 25 pts (62.5%) were none functioning. Tumor grade G1/G2/G3 were 17 pts (42.5%)/ 20 pts (50%)/ 3 pts (7.5%), and Ki 67 < 2/3-20/ > 20%/unknown was 11 pts (27.5%)/ 21 pts (52.5%)/ 3 pts (7.5%)/ 5 pts (12.5%), respectively. The most frequent site of metastasis was liver in 32 pts (80%), lymph nodes in 19 pts (47.5%), peritoneum 11 pts (27.5%) and bone 10 pts (25%). Surgery: 22 pts (55%) primary tumor surgery and 8 pts (20%) metastasectomy. Previous systemic treatments included somatostatin analogs (SSA) in 40 pts (100%), everolimus in 26 pts (65%) and sunitnib in 11 pts (27.5%), others 7 pts (17.5%). 34 pts (85%) completed 4 cycles of treatment (6 pts (15%) non-complete due to premature death). 35 pts were evaluable for early response (after 2 cycles of treatment). Early ORR and DCR were 2.8% and 74.2%, respectively. 26 pts were evaluable after finishing treatment (6 pts premature death and 8 pending evaluation). ORR and DCR were 19.2% and 92.3%. With a median follow up of 21 months, 14 pts (35%) had died. Median OS was not reached (NR) and median PFS was 27.2 m (95% CI 16.0-38.4m). Tumor grade G1-2 (p < 0.001), Ki 67 <20% (p = 0.002), primary tumor surgery (p = 0.039) and metastasectomy (p = 0.030) were associated with prolonged PFS. Mild adverse events were most frequent after the 1º doses in 27.5% patients, and medium-term toxicity was present in 25.6%, mainly hematological, G1-G2 25.6%, and G3 5%. Conclusions: 177Lu-Dotatate is a safe and effective treatment for those patients diagnosed with metastatic GEP-NET and positive somatostatin receptors, with an excellent clinical and radiological response. Furthermore, we have identified some predictive factors to OS that should be taken into consideration.

Abstract
371 Background: Inflammation plays a key role in the pathophysiology of many diseases, including cancer. Systemic inflammatory factors have been validated as indicators of ongoing systemic inflammation that could be predictive markers of poor prognosis for oncological outcomes. However, it is unknown the prognostic impact of systemic inflammation markers in patients with GEP-NETs treated with PRRT. Methods: We conducted an observational, retrospective, multicentric study of 40 patients with GEP-NET treated with PRRT belonging to GGNET (Galician Research Group on Neuroendocrine Tumors) network at Nuclear Medicine Department of Santiago de Compostela University Hospital (Spain). The systemic inflammatory markers were calculated as follows: NLR = neutrophil count/lymphocyte count, PLR = platelet count/lymphocyte count, MLR= monocyte count/lymphocyte count, ALB= albumin levels and dNLR = neutrophil count/ (leucocytes count – neutrophils count). For the calculation of the different ratios, baseline analysis and after the second dose were used. The cut-off values were determined as the median of each values, correlating them with progression-free survival (PFS). Results: Data from 40 patients (pts) treated between 2016 and 2020 were recorded. Median age was 63.5 years (range 41-85) and 55% were male. Baseline ECOG PS 0/1/2 was 15 (37.5%)/16 (40%)/9 (22.5%). Tumor location was intestinal 26 pts (65%), pancreas 11 pts (27.5%) and unknown origin 3 pts (7.5%). 15 pts (37.5%) were functioning. Tumor grade G1/G2/G3 were 17 pts (42.5%)/ 20 pts (50%)/ 3 pts (7.5%), and Ki 67 <2/3-20/>20%/unknown were 11 pts (27.5%)/ 21 pts (52.5%)/ 3 pts (7.5%)/ 5 pts (12.5%), respectively. The most frequent site of metastasis was liver 32 pts (80%), lymph nodes 19 pts (47.5%), peritoneum 11 pts (27.5%) and bone 10 pts (25%). Surgery: 22 pts (55%) primary tumor surgery and 8 pts (20%) metastasectomy. Previous systemic treatments included somatostatin analogs (SSA) 40 pts (100%), everolimus 26 pts (65%) and sunitnib 11 pts (27.5%), others 7 pts (17.5%). The baseline cutoff-values for NLR was 2.61, for PLR 110.14, for MLR 0.31, for ALB 4.2. and for dNLR 1.71. The cutoff-values after the 2nd dose for NLR was 2.3, for PLR 2.15, for MLR 0.3, for ALB 4.2 and for dNLR 1.48. With a median follow up of 21 months, 14 pts (35%) had died. Median PFS was 27.2 m (95% CI 16.0-38.4m) and OS was not reached (NR). Pts with baseline higher NLR (>2.61 vs. <2.61) had a significantly lower PFS: 15.8 m vs. NR (HR 0.181; 95% CI 0.051-0.638, p=0.03), which was also true for pts with elevated dNLR (>1.71 vs. <1.71): PFS 15.8 m vs. NR (HR 0.174; 0.049-0.614, p=0.03). Baseline PLR, ALB, MLR and NLR, PLR, ALB, dNLR and MLR values after the 2nd dose was not statistically significant for PFS. Conclusions: We have identified that baseline NLR and dNRL are significant predictive factors in patients with GEP-NETs treated with PRRT.

Efficacy and safety of Nivolumab in older patients with pretreated lung cancer: A subgroup analysis of the Galician lung cancer group. J Geriatr Oncol 2020; 12:410-415. [PMID: 33357975 DOI: 10.1016/j.jgo.2020.11.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Revised: 10/14/2020] [Accepted: 11/30/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND Nivolumab is an anti PD1 immunotherapy drug approved for advanced Non-Small Cell Lung Cancer (NSCLC) patients who previously received at least one prior line of treatment. Older patients are often not represented in clinical trials and drugs with acceptable safety profiles are necessary. We aim to report the efficacy and safety profile of Nivolumab in the real-world older subgroup of the Galician lung cancer group study. PATIENTS AND METHODS We retrospectively reviewed 188 advanced NSCLC patients treated with at least one prior therapy. We collected data from patients who were ≥70 years old treated with Nivolumab in second or subsequent lines. Patient characteristics, treatment efficacy (overall survival, progression-free survival, and response rate), and safety profile were reported. RESULTS Thirty-eight patients aged ≥70 years were included in the subgroup analysis. The median age was 74.5 years, a high percentage of patients were males (95%), most had a Performance Status of 1 (79%) and only 13% were non-smokers. The predominant histology was adenocarcinoma (53%), and 18% of patients received 2 or more lines. The median Progression-Free Survival was 7.53 months (CI 4.3-17.3, p = 0.15) and the median Overall Survival was 14.85 months (CI 10.5-20.7, p = 0.44). The objective response rate was 42%. No new adverse events were reported in comparison to a global population. CONCLUSIONS The efficacy and safety profile of Nivolumab in advanced NSCLC patients treated with at least one prior therapy and age ≥70 years old can be overlapped to a global population. Further prospective trials are needed to define and confirm these results.

The Value of PD-L1 Expression as Predictive Biomarker in Metastatic Renal Cell Carcinoma Patients: A Meta-Analysis of Randomized Clinical Trials. Cancers (Basel) 2020; 12:E1945. [PMID: 32709062 PMCID: PMC7409133 DOI: 10.3390/cancers12071945] [Citation(s) in RCA: 47] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Revised: 07/08/2020] [Accepted: 07/13/2020] [Indexed: 12/11/2022] Open
Abstract
Immune checkpoint inhibitors (ICIs) are soluble antibodies that have dramatically changed the outcomes including overall survival in a subset of kidney tumors, specifically in renal cell carcinoma (RCC). To date, there is no a single predictive biomarker approved to be used to select the patients that achieve benefit from ICIs targeting. It seems reasonable to analyze whether the programmed death-ligand 1 (PD-L1) expression could be useful. To assess the role of PD-L1 expression as a potential predictive biomarker for benefit of ICIs in RCC patients, we performed a search of randomized clinical trials (RCTs) comparing ICIs (monotherapy or in combination with other therapies) to standard of care in metastatic RCC patients according to PRISMA guidelines. Trials must have included subgroup analyses evaluating the selected outcomes (progression-free survival (PFS) and overall survival (OS)) in different subsets of patients according to PD-L1 expression on tumor samples. Hazard ratios with confidence intervals were used as the measure of efficacy between groups. A total of 4635 patients (six studies) were included (ICIs arm: 2367 patients; standard of care arm: 2268 patients). Globally, PFS and OS results favored ICIs. Differential expression of PD-L1 on tumor samples could select a subset of patients who could benefit more in terms of PFS (those with higher levels; p-value for difference between subgroups: <0.0001) but it did not seem to impact in OS results (p-value for difference: 0.63). As different methods to assess PD-L1 positivity were used among trials, this heterogeneity could have an influence on the results. PD-L1 could represent a biomarker to test PFS in clinical trials but its value for OS is less clear. In this meta-analysis, the usefulness of PD-L1 expression as a predictive biomarker to select treatment in metastatic RCC patients was not clearly shown.

Abstract
5036 Background: Atezo, which targets PD-L1, is an approved therapy for LA/M urothelial carcinoma based on the IMvigor210 and IMvigor211 trials. The single-arm SAUL study (NCT02928406) showed consistent activity and safety in a broader population, including understudied scenarios, eg pts with renal impairment or other IMvigor211 exclusion criteria. Methods: Pts with LA/M UTC received atezo 1200 mg q3w until disease progression or unacceptable toxicity. The primary endpoint was safety; secondary endpoints included overall response rate (ORR) and overall survival (OS). Post hoc analyses explored outcomes in pts classified as: chemotherapy (CT) ineligible (calculated creatine clearance [CrCl] 15– < 30 mL/min); cisplatin ineligible and carboplatin eligible (CrCl 30– < 60 mL/min); or cisplatin eligible (CrCl ≥60 mL/min). Results: Of 1004 enrolled pts, 46 (5%) were classified as CT ineligible and 420 (42%) as cisplatin ineligible. Results are summarized below. Conclusions: These post hoc analyses suggest pts typically considered cisplatin or CT ineligible are candidates for atezo. Pts with renal impairment achieved similar ORR and DCR to pts with CrCl ≥60 mL/min, without increased toxicity. Imbalances in pt characteristics may explain numerical differences in OS.

Clinical efficacy and biomarker analysis of neoadjuvant atezolizumab in operable urothelial carcinoma in the ABACUS trial. Nat Med 2019; 25:1706-1714. [PMID: 31686036 DOI: 10.1038/s41591-019-0628-7] [Citation(s) in RCA: 354] [Impact Index Per Article: 70.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Accepted: 09/25/2019] [Indexed: 12/23/2022]
Abstract
Antibodies targeting PD-1 or its ligand 1 PD-L1 such as atezolizumab, have great efficacy in a proportion of metastatic urothelial cancers1,2. Biomarkers may facilitate identification of these responding tumors3. Neoadjuvant use of these agents is associated with pathological complete response in a spectrum of tumors, including urothelial cancer4-7. Sequential tissue sampling from these studies allowed for detailed on-treatment biomarker analysis. Here, we present a single-arm phase 2 study, investigating two cycles of atezolizumab before cystectomy in 95 patients with muscle-invasive urothelial cancer (ClinicalTrials.gov identifier: NCT02662309). Pathological complete response was the primary endpoint. Secondary endpoints focused on safety, relapse-free survival and biomarker analysis. The pathological complete response rate was 31% (95% confidence interval: 21-41%), achieving the primary efficacy endpoint. Baseline biomarkers showed that the presence of preexisting activated T cells was more prominent than expected and correlated with outcome. Other established biomarkers, such as tumor mutational burden, did not predict outcome, differentiating this from the metastatic setting. Dynamic changes to gene expression signatures and protein biomarkers occurred with therapy, whereas changes in DNA alterations with treatment were uncommon. Responding tumors showed predominant expression of genes related to tissue repair after treatment, making tumor biomarker interpretation challenging in this group. Stromal factors such as transforming growth factor-β and fibroblast activation protein were linked to resistance, as was high expression of cell cycle gene signatures after treatment.

Abstract
e20645 Background: The lung immune prognostic index (LIPI) has been proposed as a new biomarker to select advanced non-small cell lung cancer (NSCLC) patients for anti-programmed cell death-1 or programmed death ligand 1 therapy. In this study, we investigate the prognostic and predictive utility of the LIPI in a multicentric nivolumab monotherapy-based cohort. Methods: 153 patients with available baseline LIPI were included. Survival estimates were calculated by the Kaplan-Meier method, and groups were compared with the log-rank test. The impact of the baseline LIPI on survival (PFS and OS), and DCR and ORR was assessed by Cox and logistic regression models respectively, adjusted for age, sex, ECOG-PS, smoking status, histology, TNM stage at diagnosis, presence of brain metastases and number of prior regimens. All p values were 2-sided, and those less than 0.05 were considered statistically significant. Results: 50.3% (n = 77) of the patients had a good (0 factors) LIPI, while 41.2% (n = 63) and 8.5% (n = 13) had intermediate (1 factor) and poor (2 factors) LIPI respectively. No significant differences were observed between the LIPI groups according to clinicopathologic characteristics. A high LIPI was significantly associated with poor OS in univariate (HR = 3.12, 95% CI 2.12 – 4.60; p < 0.0001) and multivariate (HR = 3.10, 95% CI 2.09 – 4.58; p < 0.0001) analyses. A high LIPI was associated with poor PFS (HR = 1.49, 95% CI 1.07 – 2.07; p = 0.02), but this correlation did not reach a statistical significance in multivariate analysis (HR = 1.37, 95% CI 0.98 – 1.92; p = 0.07). A higher LIPI was associated with a lower disease control rate in univariate (OR = 0.50, 95% CI 0.29 – 0.85; p = 0.01) and multivariate (OR = 0.55, 95% CI 0.31 – 0.98; p = 0.04) analyses. Conclusions: This study confirms the utility of the LIPI in prognostication and disease control prediction in advanced NSCLC patients treated with nivolumab in the second line of therapy or beyond.

Abstract
176 Background: Cabazitaxel (CBZ) improves overall survival in mCRPC that progresses during or after docetaxel treatment. CABASEM is a phase II study to evaluate the efficacy and safety of a weekly schedule of CBZ for 'unfit' (ECOG2, previous neutropenic fever with docetaxel, or radiotherapy to <25% of areas of bone marrow reserve) mCRPC patients after docetaxel failure. Fragility scales were performed to patients included before treatment and results are described. Methods: All 70 patients were treated with CBZ 10 mg/m2/wk 4 administration every 5 weeks. Geriatric fragility scales performed were Lawton daily day activities (ADL), BPI score, Katz instrumental daily day activities (IADL) and Charlson index. General and specific items have been analyzed in relation with toxicity and efficacy (clinical benefit (OR+SD), PSA response, composite PFS, PSA-PFS, and overall survival) in all patients and in older than 70 years. Results: Median age 73 (range 54-85). Charlson index and ADL scale had not relationship with any toxicity observed and any efficacy outcome in the whole group nor in older than 70. IADL independence grade was related to survival in the whole group (p=0,025) and older than 70 (p=0,02). In the whole group, some IADL items were associated with PSA response (buying, p=0.003; cooking, p=0.06; and IADL independence grade p=0.01), PSA PFS (telephone use, p=0.01; handle finances, p=0.06), composite PFS (telephone use, p=0.013; housekeeping, p=0.03; handle finances, p=0,06) and OS (telephone use p=0.001; laundry, p=0.008; handle finances, p=0.02 and IADL dependence grade, p=0.003). Only any grade diarrhea and grade 2 neutropenia was associate with buying (p=0.025) and cooking (p=0.05) IADL items respectively, in patients older than 70 years. Conclusions: IADL scale and items seem to be more related to efficacy (OS, PSA response, PFS, clinical benefit and PSA PFS) than ADL and Charlson scales in mCRPC older than 70 years treated with weekly cabazitaxel. No clear association of scales and items with toxicity were observed in this group of patients. Clinical trial information: NCT01518283.

Abstract
Background Recently, immunotherapy has changed the standard of treatment in non-small cell lung cancer (NSCLC). Outside clinical trials, data of real life is lacking. This is an observational study that represents the real world experience with nivolumab in pretreated NSCLC. Methods Eligibility criteria included, histologically confirmed NSCLC, stage IIIB and IV, evaluable disease and at least one prior therapy. Patients received nivolumab until progressive disease (PD) or unacceptable toxicity. The main aim of the study was to report the efficacy and safety profile of Nivolumab in pretreated patients with advanced NSCLC of our everyday clinical practice. The secondary aim was to perform subgroup analysis by clinical features. Results From August of 2015 to January of 2017, 188 patients were enrolled. The patients demographics were: median age 58 years, 144 male; 17 never smoker and 171 former/current smoker; 112 adenocarcinoma, 66 squamous-cell carcinoma and 10 not otherwise specified (NOS); 61 stage IIIB and 127 stage IV; 15 performance status (PS) 0, 154 PS 1 and 19 PS 2; 5 epidermal growth factor receptor (EGFR) and 1 anaplastic lymphoma kinase (ALK); 42 with central nervous system (CNS) metastases; and 71 received 2 or more prior therapy lines. Of the 188 patients enrolled, 25 (13.3%) were not evaluated, 3 (1.6%) had complete response (CR), 45 (23.9%) partial response (PR), 48 (25.5%) disease stabilization (DS) and 67 (35.6%) PD. The median of progression-free survival (PFS) was 4.83 months (95% CI, 3.6-5.9) and overall survival (OS) was 12.85 months (95% CI, 9.07-16.62). The subgroup analysis revealed statistical significance in OS for patients with CNS metastases 14.8 months (95% CI, 11.5-17.3) vs. 5.09 months (95% CI, 0.3-9.8) and also PS 0 [not reached (NR)] vs. PS 1 11.7 months vs. PS 2 3.4 months (95% CI, 2.3-4.4). The safety profile was in accordance with the literature data. Conclusions This study represents the real word experience with nivolumab and the results are consistent with previously reported in clinical trials. PS 2 and the presence of CNS metastases are associated with poor prognosis.

Abstract
Enzalutamide (MDV3100), an androgen receptor-signalling inhibitor, represents the most recent compound added to the therapeutic armamentarium for the treatment of metastatic castration-resistant prostate cancer (mCRPC) who progressed to docetaxel. The anti-tumour activity and safety of enzalutamide has been demonstrated in a phase III clinical trial, showing a benefit in overall survival, which was the primary endpoint. There are no head-to-head studies comparing the different treatment options in this subset of patients. In this article, most relevant data published in the literature have been reviewed, with special attention to the therapeutic alternatives currently available for postdocexatel mCRPC patients, emphasising the mechanisms of action of the different drugs, efficacy and quality of life-related aspects.

Abstract
Radionuclides have been widely used for cancer treatment. Recently, new research about radium-223 dichloride has been conducted in prostate cancer, which reveals that it is the first radiopharmaceutical to demonstrate an improvement in overall survival and time to first symptomatic skeletal event in patients with castration resistant prostate cancer with symptomatic bone metastases. This fact has created a new paradigm in the treatment of prostate cancer landscape, where only chemotherapy and hormone therapy had a role, while β-emitters had been confined exclusively to the role of pain relief with no impact on survival. The aim of this review is to outline current treatment approaches for advanced prostate cancer with a focus on the role of radium-223 dichloride, reviewing patients' profile that make them suitable to therapy and chances for further studies.

Abstract
235 Background: New emerging therapies for metastatic castration resistant prostate cancer (mCRPC), such as cabazitaxel (CBZ), have prompted the need to identify appropriate patients (pts) for each specific treatment. We describe preliminary data on the experience with CBZ in patients (pts) with mCRPC in Spain. Methods: Medical records from docetaxel-resistant mCRPC pts receiving CBZ at 15 centers in Spain were reviewed retrospectively. Baseline characteristics, PSA response, overall survival (OS), radiographic progression-free survival (rPFS), and toxicity were collected. Results: Data from 79 consecutive pts (median age 70) were reviewed: Eastern Cooperative Oncology Group (ECOG) zero to one (87.3%), Gleason score of 7 to 10 (87.1%), visceral involvement (24.1%), pain (74.7%), and radiological progression (68.4%) at CBZ initiation. Median duration of response to first-line androgen deprivation therapy was 20.8 months (mo). Most pts received less than or equal to two hormonal lines (72.2%) and only one docetaxel line (74.7%) before CBZ. Thirty-five (44.3%) pts had progressed on docetaxel. Progression less than six mo or greater than six mo after last docetaxel treatment was observed in 23 (29.1%) and 21 (26.6%) pts, respectively. New hormonal agents (abiraterone or enzalutamide) were given before CBZ in 2.5% of pts and after CBZ in 17.7%. Pts received a median of seven cycles (range 2 to 22) of CBZ. CBZ dose-reductions or -delays for any cause occurred in eight (10.1%) and 20 (25.3%) pts, respectively. Prophylactic G-CSF was given in 32 (40.5%) pts. A PSA decrease of greater than or equal to 50% and greater than or equal to 30% was reached in 41.2% and 48.6% of pts treated with CBZ. Median OS from first CBZ cycle was 16.2 [CI: 10.4;-] mo and median clinical and/or radiographic progression-free survival (rPFS) was 9.9 mo [CI: 7.4; 13.1]. Fourteen (17.7%) pts experienced at least one grade greater than or equal to 3 treatment-related AE, the most common being neutropenia (n=4), febrile neutropenia (n=2), asthenia (n=4), and diarrhoea (n=2). No grade greater than or equal to 3 peripheral neuropathy was reported. An analysis of factors predicting outcome will be presented. Conclusions: CBZ administered in real-life practice and in the adequate treatment setting in Spain is associated with meaningful PFS and OS and an acceptable safety profile. Dose delays and reductions were low. Prophylactic G-CSF use in 4 out of 10 pts may have contributed to these good results.

Abstract
e16095 Background: CRPC remains a therapeutic challenge, although in recent years the introduction of new agents has allowed an improvement in overall survival of these patients. In the literature there are few data on the use of cyclophosphamide in this context. The current study was designed to evaluate the efficacy and toxicity of the metronomic oral administration of a combination of cyclophosphamide and prednisone in patients with CRPC, not candidates for docetaxel or after progression to it. Methods: We retrospectively evaluated the medical records of all patients with metastatic CRPC who were treated with prednisone and cyclophosphamide in our institution. Patients had been previously treated with a docetaxel-containing regimen or were not considered candidates for taxanes, because of important comomorbidities or poor Performance Status (PS). Results: Data from 40 patients treated with cyclophosphamide 50 mg/day vo and prednisone 5 mg bid from January 2010 to December 2012 has been analyzed. Baseline characteristics of the patients are listed in the Table. 36 patients were evaluable for efficacy and toxicity. The PSA response rate (RR) was 30%, with partial responses in 7/40 patients. The clinical benefit (stabilization disease + RR) was 52%. Median progression-free survival was 13 weeks (95% CI 13.2 – 14.5). Median overall survival was 46 weeks (95% CI 26.4 – 65.9). The overall 1-year and 2-year survival were 32% and 8 %, respectively. The treatment was safe and well tolerated. Anemia (grade 0-3) was observed in a third of all patients. Conclusions: In this study in patients with a poor prognosis, metronomic oral cyclophosphamide plus prednisone have demonstrated efficacy with excelent tolerance. Oral cyclophosphamide is an interesting alternative to consider in patients non candidates for intravenous chemotherapy. [Table: see text]
