Castration Resistance

242 Background: Tumor stage, Gleason score, PSA, Performance Status have been identified as important predictors of survival in prostate cancer. The Charlson Comorbidity Index (CCI) is a validated score used to stratify patients according to comorbidities. To evaluate the prognostic role of CCI in patients with CPRC. Methods: A retrospective study based on an analysis of medical records of 212 patients with CRPC treated at Durand Hospital between 2010-2015. The CCI was calculated for each patient and a correlation with overall survival was performed. Statistical analysis included univariate analysis and multivariate analysis (Cox regression). Patients were stratified according CCI ≤ 7.6 or ≥ 7.6. Survival analysis was performed using the Kaplan-Meier curve. Results: We analyzed records of 212 patients with prostate cancer, of which 59 were resistant to castration. Median age 69 years, the PFS with androgen blockade was 32.4 months. Patients with CPRC 54% perform chemotherapy as first-line treatment of castration resistance and 46% performed treatment of hormonal manipulation (Enzalutamide or Abiraterone Acetate). Median overall survival of patients with CCI < 7.6 was 75 months versus 62 months for those with CCI > 7.6 HR: 1.19 (1.03 to 1.36) p: 0.01. In multivariate analysis the ICC was an independent predictor of mortality in these patients HR: 1.23 (1.03 to 1.48) p: 0.02. (Table 1) CCI ≤ 7,6 was predictor to subsequent lines in CPRC setting. Gleason score, PS were independent predictors of survival. Conclusions: Based on our results we can consider the CCI as an independent predictor of survival in CPRC patients. CCI could be an useful tool useful to select patients in clinical trial and community settings. [Table: see text]

Introduction: Studies on the effects of chemotherapy in Indian Castration-Resistant Prostate Cancer (CRPC) patients are very limited and world data is inconsistent. The purpose of the present study is to assess the effects of Docetaxel therapy in CRPC in Indian patients in terms of survival benet, both progression-free survival, and overall survival. This study also analyzes the effects of various factors on the survival of CRPC patients. Methodology: This is a single institutional prospective observational study. CRPC patients were treated with Docetaxel and followed till death as the primary endpoint or till the end of the study. Survivals were calculated with the Kaplan Meier method. Factors affecting survival were analyzed with univariate and multivariate analysis by log-rank t-test and Cox proportion hazard regression analysis. Result: Out of enrolled 101 patients, 78 were treated with Docetaxel. A decline in PSA (>50% reduction) was observed in 61.54%. Radiological response of regression noted in 40 % Nuclear Bone Scan and 19.23% CT/MRI by RECIST criteria. Progression-free survival and overall survival with Docetaxel (n=78) were 11.8 and 21 months respectively. Hemoglobin less than 11 gm%, Alkaline phosphatase more than 115 IU/dl, PSAmore than 14 ng/ml, Gleason score more than 7 and duration from diagnosis of carcinoma prostate to CRPC less than 24 months, the number of chemotherapy cycles less than 6 were all found to be signicantly associated with poor overall survival in univariate analysis while only Hemoglobin (P=0.0159) showed an independent association with overall survival in multivariate analysis. Conclusion: Overall and progression-free survival of CRPC patients with Docetaxel is 21 & 11.8 months respectively. Hemoglobin, Alkaline phosphatase, PSA, Gleason score, Docetaxel cycle, and duration from diagnosis of carcinoma prostate to CRPC were found to be signicantly associated with poor overall survival.

The Impact

e17582 Background: Cabazitaxel is a semi-synthetic derivative of a natural taxoid approved for the treatment of mCRPC patients (pts) after failure to docetaxel. Despite its proven efficacy, there is variability in the response, progression-free survival (PFS) and overall survival (OS) of pts. Changes in the genetic constitution of the individual such as the SNPs could explain this variability. The aim of this study was to evaluate the impact of certain SNPs in cabazitaxel activity. Methods: Clinical data from 67 mCRPC pts treated with cabazitaxel between March 2011 and October 2016 were collected. DNA was isolated from formalin fixed paraffin-embedded tumor samples. 56 SNPs in 5 genes related with metabolism and/or mechanism of action of cabazitaxel (CYP3A4, CYP3A5, ABCB1, TUBB1, CYP2C8) were chosen based on their Minor Allele Frequency, linkage disequilibrium and information from dbSNP and analyzed by TaqMan OpenArray (Lifetech). The presence/absence of mutant alleles of the selected SNPs was correlated with clinical features, progression free survival (PFS) and overall survival (OS) of prostate cancer. Chi-square test and Kaplan-Meier with log-rank test were used for statistical analyses. Results: The median age was 61 years (range 44-82). 56.7% (n = 38) had a Gleason score ≥8 and 94% had received docetaxel in first line. Type of response to cabazitaxel was associated with median OS (Partial response = 24.35 months, Stable disease = 11.16 months, Progression disease = 5.8 months; p= 0.045). Univariate analysis, showed worsed OS at 1 year for wild type status of SNP rs151352 (OR = 4, 95%CI 1.27-12.58, p= 0.029). In addition, two SNPs (rs11773597, rs1202186) were associated with radiological response to cabazitaxel ( p= 0.031 and p= 0.030 respectively). Other 7 SNPs (rs11773597, rs2235040, rs1045642, rs1419745, rs1202170, rs6949448, rs11572093) were associated ( p<0.05) with Gleason score, pain, PSA doubling time, febrile neutropenia and asthenia. Conclusions: A particular SNP profile could be predictive of efficacy and related with toxicity in mCRPC population treated with cabazitaxel after progression to docetaxel. These outcomes become particularly relevant in patient selection given the recent results of the CARD trial.

591 Background: To investigate the prognostic value of the pretreatment inflammatory characteristics on treatment response and survival. Methods: We included 151 patients with metastatic renal cell carcinoma (mRCC) Patients’ charts were retrospectively analyzed for their clinical, pathological and demographic features. Systemic immune inflammation index (SII) cut off is estimated with median value. Overall survival (OS) was estimated by Kaplan-Meier method for univariate analysis and Cox-regression for multivariate analysis. Results: In high SII group (SII > 844) overall survival is 11 months and in low SII group (SII < 844) overall survival is 22 months (p = 0,008). Median OS is lower in the hypercalcemic group (7 months vs.18 months, P = 0,013). In patients with anemia and thrombocytosis, OS is lower (41 months vs. 13 months p = 0,001 and 6 months vs. 18 months p = 0,01). In multivariate analysis, anemia, SII, and ECOG performance status were able to predict OS (HR = 2,69, HR = 2,04, HR = 2,57) Conclusions: In patients with mRCC, SII may have a prognostic value and higher score may related with decreased overall survival.

e16565 Background: Sipuleucel-T (Sip-T) is a cellular-based cancer immunotherapy for men with asymptomatic or minimally symptomatic mCRPC. Its approval was based on overall survival (OS) benefit in randomized placebo-controlled phase 3 trials. However, treatment was associated with PSA decline in only a small minority of pts. Understanding clinical factors predictive of OS may help to guide treatment decisions, including pt selection and timing of Sip-T relative to other therapies. Methods: This is a retrospective chart review of mCRPC pts treated with Sip-T at UCSF between April 2010 and April 2016. All pts completed 3 Sip-T infusions. Patients with localized prostate cancer treated with neoadjuvant Sip-T (NCT00715104) and pts with mCRPC treated with an ongoing phase 2 Sip-T/Ipilimumab trial (NCT01804465) were excluded. Kaplan-Meier method was used to estimate OS. The predictive value of candidate variables – including age, ECOG performance status (PS), Gleason score, metastatic volume, baseline PSA, baseline PSADT, prior abiraterone or enzalutamide, and prior chemotherapy – was assessed using univariate and multivariate Cox proportional hazard model. Results: Of 43 patients evaluated to date, 74.4% had ECOG PS 0, 88.4% had bone +/- nodal metastasis, 81.4% had low metastatic volume, 9.3% had prior abiraterone, 2.3% had prior enzalutamide, and 9.3% had prior chemotherapy. The median age was 69 years (range 53-85), median baseline PSA was 8.3 ng/mL (range 0.05-227.9) and median PSA doubling time (PSADT) was 3.9 mo (range 1.4-15.1). At a median follow-up of 21.4 mo, the median OS was 34.1 mo (95% CI 25.7-41.4). Univariate analysis showed that ECOG PS (HR 6.66, p < 0.001) and PSA (log-transformed) (HR 3.36, p = 0.002) were significantly associated with OS. There was a trend towards worse OS with faster baseline PSADT (log-transformed) (HR 0.16, p = 0.11) and prior chemotherapy (HR = 4.13, p = 0.11). By multivariate analysis, ECOG PS, baseline PSA and baseline PSADT were statistically significant (p < 0.05). Conclusions: In this ongoing retrospective cohort, ECOG PS, baseline PSA and baseline PSADT were associated with OS in mCRPC patients treated with Sip-T.

e16522 Background: Cs are commonly used in the treatment of mCRPC, because of their inhibitory effects on the secretion of ACTH and their palliative effects. Inhibition of ACTH results in downregulation of adrenal androgens. Cs may have a cytotoxic effect on prostate cancer cells, mediated in part by the downregulation of androgen receptors and the activation of glucocorticoid receptor-mediated signaling and downstream antiangiogenic activity. The rationale for adding Cs to D chemotherapy is for the management of symptoms and adverse events rather than for improving responses. D (without Cs) + ADT (androgen-deprivation therapy) vs ADT alone in castration-sensitive prostate cancer has resulted in significant increase in survival (NEJM, 2015). Cs has been reported to adversely influence OS during enzalutamide (NEJM, 2012). In the COU-AA-301 trial Cs use at baseline was an independent prognostic factor in multivariate analysis, but not in a stepwise selection model (JCO, 2013). Methods: We performed a retrospective analysis of 117 mCRPC pts treated with D. All pts had standard Cs premedication before D and 74 pts received prednisone 5 mg po BID, but 43 pts didn’t get continuous Cs therapy. Kaplan-Meier estimates and Cox regression model were used. Results: Pts characteristics were as follows: median age 66 yrs (range 48-81), Gleason score ≤6: 22pts, ≥7: 61pts. (34 NA). Altogether 1015 cycles of D were given, median 8 (range 2-27). Subsequent therapies were as follows: Abiraterone Acetate (AA) (75), Mitoxantrone (46), Xofigo (5), other chemotherapies (7), none (21). Pts receiving Cs had an inferior OS in all subgroups, although none was significant (Table). Only the Gleason score was an independent prognostic factor in multivariate analysis. Conclusions: Our data suggest, that D therapy withouth Cs is at least as effective as the combination. More data is neccesary to support the suspicion of negative influence of Cs on OS. Thus unnecesarry Cs treatment might be ommited. [Table: see text]

e597 Background: The standard treatment for metastatic castration-resistant prostate cancer (MCRPC) is Docetaxel (DTX); however, it has serious adverse effects. It is necessary to know the prognostic factors for overall survival (OS) of patients with MCRPC treated with DTX. The aim of this study was to determine the prognostic factors for OS in patients with MCRPC treated with DTX. Methods: This study is a secondary analysis of the control arms of the clinical trials NTC00273338, NCT00519285 and NCT00988208. 1600 patients aged 18 years or older with MCPRC that received DTX and prednisone were included. Survival curves were estimated by Kaplan-Meier and comparison was done by log-rank test. Multivariate analysis for overall survival (OS) was performed with the Cox proportional hazard regression model. Results: The median OS time was 14.64 months. The 1-yr-OS and 2-yrs-OS were 86.2% and 28.6%, respectively. Patients with an ECOG score greater than 0 lived significantly less than the rest of patients (p = 0.00). The patients with an alkaline phosphate level (ALP) > 200 had significantly lower OS (p = 0.00). In the multivariate analysis, the factors that influenced OS were ECOG, ALP, HB, LDH and number of metastases. Conclusions: Poor performance status, high alkaline phosphatase level, low hemoglobin level, high LDH and more than 2 metastases were the main prognostic factors in patients with metastatic castration resistant prostate cancer.

e16019 Background: Several signal transduction pathways,important for apoptosis and angiogenesis were idendified and their expression and correlation with survival was studied by IHC in archival prostate cancer biopsies. All pts has androgen deprivation for stage D2 disease and were followed at 3 month intervals. Methods: In an IRB approved study,42 pts had adequate tissue preserved between 1992 and 2006 and their charts were reviewed retrospectively.IHC stains to detect tumor expression of S6(ribosomal),p70s6,pTEN,AKT-1,BCL-1(Cyclin D1),VEGF,c-KIT,PDGFR-alpha and PDGFR-beta were performed by US Labs(Irvine,CA).All results were independently evaluated by two pathologists.Immunoreactivity was scored using a semiquantitative system combining intensity of staining(0–3+) and percentage of cells staining positive(0–3+).The total score was obtained by adding the scores for indensity and the percentage of positive cells,then averaging the resuts obtained by each reader.For the purpose of this study, stain intensity of 0–1+ was considered negative and the intensity of 2–3+ was considered positive.A Cox regression survival model for each stain was developed with variables known to predict survival :Gleason score,Hemoglobin(Hgb),Alkaline Phosphatase(Alk Phos),Prostate Specific Antigen(PSA),Lactate Dehydrogenase(LDH) levels. Results: The median values were: age 70yrs(56–92),Gleason score 8(6–10), LDH 171 IU/L(97–350),Hgb 12.9gm/dl (6.8–16.3), PSA 188ng/ml(2–5677),Alk Phos 139U/L(60–1756),survival 851 days(163- 6102).In univariate analysis,VEGF staining was predictive of survival (p<0.037) but not in multivariate analysis.The pTEN staining correlated with survival (p<0.0367) and a hazard ratio of 0.040 in multivariate analysis. Conclusions: In this small sample of pts, overexpression of S6,p70s6,AKT-1,BCL-1,VEGF,c-KIT,PDGFR-alpha and PDGFR-beta by IHC staining did not predict survival independently.The pTEN staining,however was strong predictor of survival in the multivariate analysis. No significant financial relationships to disclose.

Abstract Background: We compared outcomes and toxicities between concurrent retrograde super-selective intra-arterial chemoradiotherapy (IACRT) and concurrent systemic chemoradiotherapy (SCRT) for gingival carcinoma (GC).　Methods: We included 84 consecutive patients who were treated for non-metastatic GC ≥ stage III, from 2006 to 2018, in this retrospective analysis (IACRT group: n=66; SCRT group: n=18).Results: The median follow-up time was 24 (range: 1–124) months. The median prescribed dose was 60 (6–70.2) Gy (IACRT: 60 Gy; SCRT: 69 Gy). There were significant differences between the two groups in terms of 3-year overall survival (OS; IACRT: 78.8%, 95% confidence interval [CI]: 66.0–87.6; SCRT: 50.4%, 95% CI: 27.6–73.0; P = 0.039), progression-free survival (PFS; IACRT: 75.6%, 95% CI: 62.7–85.2; SCRT: 42.0%, 95% CI: 17.7–70.9; P = 0.028) and local control rates (LC; IACRT: 77.2%, 95% CI: 64.2–86.4; SCRT: 42.0%, 95% CI: 17.7–70.9; P = 0.015). In univariate analysis, age ≥ 65 years, decreased performance status (PS) and SCRT were significantly associated with worse outcomes (P < 0.05). In multivariate analysis, age ≥ 65 years, clinical stage IV, and SCRT were significantly correlated with a poor OS rate (P < 0.05). Patients with poorer PS had a significantly worse PFS rate. Regarding acute toxicity, 22 IACRT patients had grade 4 lymphopenia, and osteoradionecrosis was the most common late toxicity in both groups.Conclusions: This is the first report to compare outcomes from IACRT and SCRT among patients with GC. ALL therapy related toxicities were manageable. IACRT is an effective and safe treatment for GC.

Purpose Several studies have reported that among patients with localized prostate cancer, black men have a shorter overall survival (OS) time than white men, but few data exist for men with advanced prostate cancer. The primary goal of this analysis was to compare the OS in black and white men with metastatic castration-resistant prostate cancer (mCRPC) who were treated in phase III clinical trials with docetaxel plus prednisone (DP) or a DP-containing regimen. Methods Individual participant data from 8,820 men with mCRPC randomly assigned in nine phase III trials to DP or a DP-containing regimen were combined. Race was based on self-report. The primary end point was OS. The Cox proportional hazards regression model was used to assess the prognostic importance of race (black v white) adjusted for established risk factors common across the trials (age, prostate-specific antigen, performance status, alkaline phosphatase, hemoglobin, and sites of metastases). Results Of 8,820 men, 7,528 (85%) were white, 500 (6%) were black, 424 (5%) were Asian, and 368 (4%) were of unknown race. Black men were younger and had worse performance status, higher testosterone and prostate-specific antigen, and lower hemoglobin than white men. Despite these differences, the median OS was 21.0 months (95% CI, 19.4 to 22.5 months) versus 21.2 months (95% CI, 20.8 to 21.7 months) in black and white men, respectively. The pooled multivariable hazard ratio of 0.81 (95% CI, 0.72 to 0.91) demonstrates that overall, black men have a statistically significant decreased risk of death compared with white men ( P < .001). Conclusion When adjusted for known prognostic factors, we observed a statistically significant increased OS in black versus white men with mCRPC who were enrolled in these clinical trials. The mechanism for these differences is not known.

Abstract Background We compared outcomes and toxicities between concurrent retrograde super-selective intra-arterial chemoradiotherapy (IACRT) and concurrent systemic chemoradiotherapy (SCRT) for gingival carcinoma (GC). Methods We included 84 consecutive patients who were treated for non-metastatic GC ≥ stage III, from 2006 to 2018, in this retrospective analysis (IACRT group: n = 66; SCRT group: n = 18). Results The median follow-up time was 24 (range: 1–124) months. The median prescribed dose was 60 (6–70.2) Gy (IACRT: 60 Gy; SCRT: 69 Gy).

In univariate analysis, age ≥ 65 years, decreased performance status (PS) and SCRT were significantly associated with worse outcomes (P < 0.05). In multivariate analysis, age ≥ 65 years, clinical stage IV, and SCRT were significantly correlated with a poor OS rate (P < 0.05). Patients with poorer PS had a significantly worse PFS rate. Regarding acute toxicity, 22 IACRT patients had grade 4 lymphopenia, and osteoradionecrosis was the most common late toxicity in both groups. Conclusions This is the first report to compare outcomes from IACRT and SCRT among patients with GC. ALL therapy related toxicities were manageable. IACRT is an effective and safe treatment for GC.
