Solute Carrier Transporter

303 Background: Hepatocellular carcinoma (HCC) is the third cause of cancer-related death. GNS561 (Genoscience Pharma, France) is a small molecule inducing apoptosis by lysosome inhibition and caspase activation. GNS561 has high hepatotropism and anti-tumorigenic capacity on tumor bulk and cancer stem cells. Its main target is a specific solute carrier transporter (SLCt). We describe here the clinical relevance of the overexpression of SLCt in HCC patients. Methods: The expression of SLCt was investigated by iQRT-PCR in surgically resected HCC tumors (T) and the matched non-tumor (NT) liver tissues (n=180) as well as healthy livers (HL) devoid of chronic or acute disease (n=10). Pearson's chi-squared test was employed for significant correlation tests while univariate and multivariate survival analysis were performed by Cox proportional hazard ratio (HR) method. Results: SLCt was overexpressed in 40.5% of T and 30.3% of NT as compared to HL. High SLCt in T was associated with microvascular emboli (p=0.034) and expression of the cancer stem cell markers Sox2 (p=0.025) and CD133 (p=0.034). High SLCt in NT correlated with cirrhosis (p=0.009) and presence of satellite nodules (p<0.001). Univariate analysis showed association between high SLCt in T and shortened overall survival (OS) (HR=1.08, p=0.020), lower progression-free survival (PFS) (HR=1.76, p=0.006) as well as early recurrence-free survival (ERFS) (within 2 years post-surgery) (HR=1.88, p=0.008). In multivariate analysis, high SLCt tended to be an independent factor for OS, and this was strongly significant for PFS and ERFS. High SLCt in NT, is quite a poor outcome factor on late recurrence-free survival (HR=2.33, p=0.056) together with cirrhosis in univariate analysis, but remained dependent of cirrhosis in multivariate analysis. Late recurrence is linked to the intrinsic tumorigenic status of the liver. Conclusions: Overexpression of the SLCt in HCC tumors is associated to stemness features and appears as a poor outcome factor impacting on early recurrence. Further, SLCt in NT is associated with development of de-novo HCC. Validation cohorts and prospective assessments are needed to define high SLCt as a potential biomarker of HCC stemness and patient outcome.

Aim. To determine the factors associated with early recurrence in patients with distal cholangiocarcinoma after pancreaticoduodenectomy (PD).Patients and Methods. Sixty-one patients with distal cholangiocarcinoma were enrolled. The clinical data and histopathological findings were collected retrospectively.Results. Patients were divided into two groups as follows: 16 patients (26%) with early recurrence and 45 patients (74%) with late recurrence or no recurrence. In a univariate analysis, lymph node metastases (P=0.0016), lymphatic invasion (P<0.0001), pancreatic invasion (P=0.0006), and perineural invasion (P=0.0004) were significantly different between the two groups. In a multivariate analysis, a higher incidence of lymphatic invasion was the only independent risk factor for early recurrence (odds ratio: 5.772, 95% confidence interval: 1.123–29.682,P=0.036). Moreover, the disease-free survival and overall survival of patients with a higher incidence of lymphatic invasion were significantly worse compared with those of patients with a lower incidence of lymphatic invasion (P<0.001).Conclusions. Our study showed that a higher incidence of lymphatic invasion was a significant predictor of early recurrence in patients with distal cholangiocarcinoma. Therefore, lymphatic invasion might be useful in determining the optimal adjuvant therapy in the early postoperative stage for distal cholangiocarcinoma.

314 Background: As surgery for esophageal carcinoma in the elderly people has been increasing, sarcopenia is a severe problem not only in complications, but also in long-term prognosis. However, the relationship between perioperative skeletal muscle loss especially in the early postoperative period and long-term prognosis has not been clarified. Methods: This study retrospectively analyzed 152 patients with thoracic esophageal carcinoma who had underwent radical esophagectomy in our institution from April 2008 to March 2015 (Patients with postoperative hospital stay longer than 6 weeks were excluded). As an index of perioperative sarcopenia, total psoas muscle area (TPA) was measured before surgery (as baseline), at postoperative day (POD) 7 and postoperative month (POM) 6 from CT images. We investigated the correlation between the change of TPA and the postoperative survival. Results: Of 152 patients, 52 (34.2%) showed a TPA decrease from baseline to POD 7, and 98 (64.5%) showed a TPA decrease from baseline to POM 6. At the time of POD 7, overall survival (OS) decreased significantly in a TPA decrease group (P = 0.008, 5-year survival rate: non-decrease group 82.3% / decrease group 56.8%). Recurrence free survival (RFS) was also significantly decreased in a TPA decrease group (P < 0.001, 5-year recurrence free survival rate: non-decrease group 73.7% / decrease group 44.9%). On the other hand, at the time of POM 6, OS and also RFS had no significant difference between decrease and non-decrease groups. In univariate analysis for OS, pStage ≥3 and TPA decrease at POD 7 had poor prognosis. In multivariate analysis for OS, pStage ≥3 (HR:5.516, P < 0.001, 95%CI:2.634-11.551) and TPA decrease at POD 7 (HR:2.036, P = 0.047, 95%CI:1.010-4.103) were also independent poor prognostic factors. In the univariate analysis for RFS, pStage ≥3, TPA decrease at POD 7 and age ≥60 years had poor prognosis. In multivariate analysis, pStaeg ≥3 (HR:3.831, P < 0.001, 95%CI:2.182-6.728) and TPA decrease at POD 7 (HR:1.942, P = 0.021, 95%CI:1.104-3.416) were independent poor prognostic factors. Conclusions: Our findings suggest that the TPA decrease early in a postoperative period has poor prognosis on OS and also RFS.

Abstract Background Hypofractionated post-prostatectomy radiotherapy is emerging practice, however with no randomized evidence so far to support it’s use. Additionally, patients with persistent PSA after prostatectomy may have aggressive disease and respond less well on standard salvage treatment. Herein we report outcomes for conventionally fractionated (CFR) and hypofractionated radiotherapy (HFR) in patients with persistent postprostatectomy PSA who received salvage radiotherapy to prostate bed. Methods Single institution retrospective chart review was performed after Institutional Review Board approval. Between May 2012 and December 2016, 147 patients received salvage postprostatectomy radiotherapy. PSA failure-free and metastasis-free survival were calculated using Kaplan–Meier method. Cox regression analysis was performed to test association of fractionation regimen and other clinical factors with treatment outcomes. Early and late toxicity was assessed using Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0. Results Sixty-nine patients who had persistent PSA (≥ 0.1 ng/mL) after prostatectomy were identified. Median follow-up was 67 months (95% CI 58–106 months, range, 8–106 months). Thirty-six patients (52.2%) received CFR, 66 Gy in 33 fractions, 2 Gy per fraction, and 33 patients (47.8%) received HFR, 52.5 Gy in 20 fractions, 2.63 Gy per fraction. Forty-seven (68%) patients received androgen deprivation therapy (ADT). 5-year PSA failure- and metastasis-free survival rate was 56.9% and 76.9%, respectively. Thirty patients (43%) experienced biochemical failure after salvage radiotherapy and 16 patients (23%) experienced metastatic relapse. Nine patients (13%) developed metastatic castration-resistant disease and died of advanced prostate cancer. Median PSA failure-free survival was 72 months (95% CI; 41–72 months), while median metastasis-free survival was not reached. Patients in HFR group were more likely to experience shorter PSA failure-free survival when compared to CFR group (HR 2.2; 95% CI 1.0–4.6, p = 0.04). On univariate analysis, factors significantly associated with PSA failure-free survival were radiotherapy schedule (CFR vs HFR, HR 2.2, 95% CI 1.0–4.6, p = 0.04), first postoperative PSA (HR 1.02, 95% CI 1.0–1.04, p = 0.03), and concomitant ADT (HR 3.3, 95% CI 1.2–8.6, p = 0.02). On multivariate analysis, factors significantly associated with PSA failure-free survival were radiotherapy schedule (HR 3.04, 95% CI 1.37–6.74, p = 0.006) and concomitant ADT (HR 4.41, 95% CI 1.6–12.12, p = 0.004). On univariate analysis, factors significantly associated with metastasis-free survival were the first postoperative PSA (HR 1.07, 95% CI 1.03–1.12, p = 0.002), seminal vesicle involvement (HR 3.48, 95% CI 1.26–9.6,p = 0.02), extracapsular extension (HR 7.02, 95% CI 1.96–25.07, p = 0.003), and surgical margin status (HR 2.86, 95% CI 1.03–7.97, p = 0.04). The first postoperative PSA (HR 1.04, 95% CI 1.00–1.08, p = 0.02) and extracapsular extension (HR 4.24, 95% CI 1.08–16.55, p = 0.04) remained significantly associated with metastasis-free survival on multivariate analysis. Three patients in CFR arm (8%) experienced late genitourinary grade 3 toxicity. Conclusions In our experience, commonly used hypofractionated radiotherapy regimen was associated with lower biochemical control compared to standard fractionation in patients with persistent PSA receiving salvage radiotherapy. Reason for this might be lower biological dose in HFR compared to CFR group. However, this observation is limited due to baseline imbalances in ADT use, ADT duration and Grade Group distribution between two radiotherapy cohorts. In patients with persistent PSA post-prostatectomy, the first postoperative PSA is an independent risk factor for treatment failure. Additional studies are needed to corroborate our observations.

Abstract Background The inflammation indexes in blood routine play an essential role in evaluating the prognosis of patients with hepatocellular carcinoma, but the effect on early recurrence has not been clarified. The study aimed to investigate the risk factors of early recurrence (within 2 years) and recurrence-free survival after curative hepatectomy and explore the role of inflammatory indexes in predicting early recurrence. Methods The baseline data of 161 patients with hepatocellular carcinoma were analyzed retrospectively. The optimal cut-off value of the inflammatory index was determined according to the Youden index. Its predictive performance was compared by the area under the receiver operating characteristic curve. Logistic and Cox regression analyses were used to determine the risk factors of early recurrence and recurrence-free survival. Results The area under the curve of monocyte to lymphocyte ratio (MLR) for predicting early recurrence was 0.700, which was better than systemic inflammatory response index (SIRI), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and systemic immune-inflammatory index (SII). MLR, tumour size, tumour differentiation and BCLC stage are all risk factors for early recurrence and recurrence-free survival of HCC. Combining the above four risk factors to construct a joint index, the area under the curve for predicting early recurrence was 0.829, which was better than single MLR, tumour size, tumour differentiation and BCLC stage. Furthermore, with the increase of risk factors, the recurrence-free survival of patients is worse. Conclusion The combination of MLR and clinical risk factors is helpful for clinicians to identify high-risk patients with early recurrence and carry out active postoperative adjuvant therapy to improve the prognosis of patients.

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.

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.

Abstract INTRODUCTION: T-cell depleted allogeneic peripheral blood stem cell transplant (TCD PBSCT) using CD34 selection achieves relapse rates comparable to those of unmodified grafts (Pasquini et al., JCO 2012), but disease-related predictors of outcome have not been fully characterized in the TCD setting. We evaluated the prognostic utility of the refined Disease Risk Index (DRI; Armand et al., Blood 2014) in TCD PBSCT. METHODS: This was a retrospective analysis of patients who underwent first allogeneic HCT with TCD PBSCT for AML, ALL, or MDS at a single center between 1/2000 and 12/2015. Overall survival (OS), relapse-free survival (RFS), and chronic GVHD/relapse-free survival (CRFS) were estimated by the Kaplan-Meier method. Cumulative incidence of relapse, non-relapse mortality (NRM), acute GVHD (aGVHD), and chronic GVHD (cGVHD) were estimated using the cumulative incidence method for competing risks. The univariate association between variables of interest and OS/RFS/CRFS was evaluated using the log-rank test; Cox regression models assessed the adjusted effect of significant covariates on OS and RFS. Given only 1 patient with very high DRI, the high/very high DRI groups were combined. Similarly, given few patients with low DRI, the low/intermediate groups were combined in multivariate analysis. RESULTS: The analysis comprised a total of 519 patients. Median age was 55 years (range 18-73). There were 302 patients (58%) transplanted for AML, 144 (28%) for MDS, and 73 (14%) for ALL. Seventeen patients had low DRI scores (3%), 431 intermediate (83%), and 71 high/very high (14%). Median follow-up among survivors was 53.1 months (range 4.6-171.0). Two-year estimates for outcomes of interest were OS 62.8% (95% CI 58.5, 66.9), RFS 58.1% (95% CI 53.7, 62.3), and CRFS 54.0% (95% CI 49.5, 58.2). The cumulative incidence of relapse at 2 years was 17.3% (95% CI 14.2, 20.7). There were 0 relapse events in patients with low DRI, whereas intermediate and high/very high DRI scores were associated with a significantly increased incidence of relapse (p &lt; 0.001), with 2 year estimates 14.7% (95% CI 11.5, 18.3) and 37.1% (95% CI 25.8, 48.4), respectively. The cumulative incidence of NRM was 24.6% (95% CI 20.9, 28.4) at 2 years. The cumulative incidence of aGVHD at 100 days was 12.5% (95% CI 9.8, 15.5) for grade 2-4 and 2.5% for grade 3-4 (95% CI 1.4, 4.1); with a cumulative incidence of cGVHD of 4.7% (95% CI 3.1, 6.7) at 1 year. NRM, aGVHD, and cGVHD did not vary with DRI. In univariate analysis, DRI was associated with significant differences in OS, RFS, and CRFS (Table 1; Figure). Additional factors associated with poorer OS in univariate analysis were HCT-CI score &gt; 0, KPS &lt; 90, donor type (matched unrelated or mismatched vs. matched related donor), and age &gt; the median of 55.3 years; HCT-CI and KPS also correlated with significant differences in RFS. On multivariate analysis (Table 2), high/very high DRI corresponded to significantly greater risk of death (HR 1.72 for OS, [95% CI 1.24, 2.40]) and relapse or death (HR 1.86 for RFS [95% CI 1.35, 2.55]), compared with low/intermediate DRI. Multivariate analysis also showed that KPS &lt; 90 was associated with worse OS and RFS, as did a higher HCT-CI score. Neither age nor donor type was significantly associated with OS in multivariate analysis. CONCLUSION: In a large cohort of patients undergoing first TCD PBSCT at a single center for acute leukemia or MDS, DRI score significantly correlated with relapse incidence as well as OS, RFS, and CRFS. We have previously shown that the HCT-CI score, which incorporates patients' baseline comorbidities, is also predictive of outcomes after TCD PBSCT. Combining these prognostic tools will serve to better select appropriate patients for TCD PBSCT, a transplant approach currently under investigation in a multicenter phase 3 trial (BMT CTN 1301).

Abstract Introduction: Myelodysplastic syndrome with del5q (MDSdel5q) is the only cytogenetically defined MDS category recognized by WHO in 2001, 2008 and 2016 and is defined as a MDS with deletion on the long arm of chromosome 5 and less than 5% of blast cells in bone marrow. It is known that for patients with MDSdel5q and transfusion dependence (TD), Len (LEN) is the first choice of treatment. However, data regarding factors that may impact on the development of TD or disease evolution in patients diagnosed without TD are scanty. In our study a retrospective multicenter analysis on patients with low-int 1 MDSdel5q without TD at diagnosis has been performed in order to answer these questions. Patients and methods: We performed a multicenter collaborative research from the Spanish (RESMD) and German MDS registries. Data from 153 low risk MDSdel5q without TD at diagnosis were retrospectively analyzed. Statistical analysis: Data were summarized using median, range, and percentage. The event of TD was defined as the development of TD according to the IWG criteria (2006) and/or the beginning of a treatment which could modify disease course (LEN or ESA). Transfusion or treatment free survival (TFS), overall survival (OS) and leukemia free survival (LFS) were measured from diagnosis to TD or treatment, the first occurred (or to last follow up if none), last follow up or death from any cause and evolution to AML, respectively. TFS, OS and LFS were analyzed using the Kaplan Ð Meier method. The Log-rank test was used to compare variables and their impact on survival for univariate analysis.Multivariate analysis was performed using Cox's proportional hazards regression model. For comparison of Kaplan Meier curves the long rank test was used, with statistical significance with p<0.05. Statistical analysis was performed using SPSS 20.0. Results: Main clinical and biological characteristics were summarizing in table 1. From the total of 153 patients, finally 121 were evaluable. During the study 56 patients (46.2%) became in TD and 47 (38.8%) did not develop TD but received a modified disease course treatment. In this sense, most of the patients developed relevant anemia regarding those data (103 out of 121 patients, 85%). Median time to TD or treatment (TFS) was 20 months (1-132) from diagnosis. Secondary MDS (p=0.02), thrombocytosis (>350 109/L) (p=0.007), and neutropenia (<1.5 x 109/L) (p=0.02) were associated with poorer TFS. Thrombocytosis and neutropenia retained statistical significance in the multivariate analysis (Table 2). Among the TD patients (N=56), 42 (75%) received treatment: 28 LEN, 7 ESA and 7 other treatments. Among patients that did not develop TD (N=65), 47 (72.3%) received treatment before TD development: 16 LEN, 28 ESA and 3 other treatments. In order to know the evolution of these patients, survival analysis was performed. Median follow up was 58.9 months among alive patients and 57% of them were alive at the time of the last follow up. Estimated OS at 2 and 5 years was 94% and 64%. Regarding Univariate analysis, platelet <100 x 109/L (p=0.03), patients older than 71 years (p=0.001), and progression into AML (p=0.02) were associated with poorer OS. On the contrary, patients who had received treatment showed better OS (p<0.0001). This benefit is more evident among patients receiving LEN, median OS for patients receiving LEN, ESA/other treatments and not treated group was 137 months (CI 95%: 59,4 -215,5), 99,3 months (CI 95%: 46,6 -152) and 57,9 months (CI 95%: 38,2 -77,6), respectively, p<0.0001 (Figure 1). In the multivariate analysis, patients older than 71 years and LEN treatment retained the statistical significant impact on OS (Table 2). Twenty-eight patients (23%) progressed into AML, median time to AML was 35 months (5-122). When univariate analysis was performed, variables with adverse impact on LFS were platelets <100 x 109/L(p=0.019), neutropenia < 0.8 x 109/L (p=0.026), an additional cytogenetic abnormality (p=0.013) while treatment with LEN had a favorable impact (p=0.035). In the multivariate analysis only the presence of additional cytogenetic abnormalities retained statistical significance (Table 2). CONCLUSIONS: Most of the patients with low risk del(5q) MDS and no TD at diagnosis developed symptomatic anemia very early after diagnosis (20 months). Carefully monitoring should be stablished in order to detect this time point. Outcome of this subset of patients could improve after target therapy. Figure 1 Figure 1.

Predictors Of Recurrence

20114 Background: Identification of patients at high risk for recurrence remains a central issue in the treatment of colorectal cancer. Our goal was to identify predictive factors for recurrence in colorectal cancer patients. Methods: DNA from 84 colorectal cancers were analyzed for wide-ranging allelotyping. Using 27 microsatellite markers spanning every 10cM on chromosome 17 and 18, we defined the LOH-ratio as the proportion of markers which show LOH out of 27 markers. Tumors were grouped into two groups by the median value of LOH-ratio (0.19). Recurrence free survival was compared with Kaplan-Meier analysis and log rank statistic. The Cox proportional hazards regression model was used for both univariate and multivariate analysis of recurrence free survival. Results: Log rank statistic revealed that LOH-ratio, stage, lymph node metastasis significantly related to recurrence free survival. On univariate analysis, significant predictors of Recurrence free survival were LOH-ratio, lymph node metastasis, Dukes’ classification, and pathological type. On multivariate analysis, LOH-ratio (HR 3.1, p = 0.02) and lymph node metastasis (HR 5.2, p = 0.002) independently predicted for recurrence free survival. Conclusions: LOH-ratio and lymph node metastasis were the only independent predictors of recurrence free survival. Altogether with lymph node metastasis, LOH-ratio could help to improve postoperative surveillance and adjuvant therapy. No significant financial relationships to disclose.
