Abstract Backgroud: Our understanding in prognosis of bone metastasis (BM) from colorectal cancer (CRC) is limited. We aimed to establish a clinical risk stratification for individually predicting the survival of CRC patients with BM.Methods: A total of 200 CRC patients with BM were included in this study. Survival time from BM diagnosis was estimated using the Kaplan-Meier method. The multivariable COX regression model identified the risk factors on cancer specific survival (CSS). Based on weighted scoring system, the stratification model was constructed to classify patients with BM according to prognostic risk. Discrimination power and calibration ability of risk stratification were measured.Results: The median CSS time was 11 months after BM diagnosis. Lymph node metastasis, CA199 levels, bone involvement, KPS scores, primary tumor resection, bisphosphonates therapy and radiotherapy were identified as predictors of CSS. Four risk groups were stratified according to weighted scoring system, including low risk, medium risk, medium-high risk and high risk group, with 35, 16, 9 and 5 months of median CSS, respectively (P = 0.000). The risk stratification displayed good accuracy in predicting CSS, with acceptable discrimination and calibration.Conclusion: This novel risk stratification predicts CSS in CRC patient with BM using easily accessible clinicopathologic factors, which is recommended for use in individualized clinical decision making in patient with BM.

5076 Background: We hypothesized that in patients with pT2N0 transitional cell carcinoma (TCC) of the urinary bladder, residual muscle-invasive disease at radical cystectomy (RC) may confer poorer outcomes than residual non-muscle invasive disease due to larger tumor volume and/or biologically more aggressive disease. Patients with high-risk pT2N0 disease may be candidates for trials of adjuvant therapy. Methods: Patients from the BCRC database with pT2N0 stage (N = 208) at TUR (transurethral resection) whose tumors were organ-confined at RC (≤pT2N0) were analyzed. T1N0 patients (N=33) with pT2 disease at RC were also examined in order to include all pT2 patients. None of the patients had received perioperative chemotherapy. The effect of residual pT-stage at RC on outcomes was evaluated in Kaplan-Meier, as well as in univariable and multivariable Cox-regression models. Covariates consisted of age, gender, grade, lymphovascular invasion, concomitant carcinoma-in-situ (CIS), number of lymph nodes removed, and the year of surgery. Results: Among baseline T2N0 patients, residual pT-stage at RC was pT0 in 24 (11.5%), pTa in 9 (4.3%), pCIS in 22 (10.6%), pT1 in 35 (16.8%), and pT2 in 118 patients (56.7%). The median follow-up was 50.1 months. The 5-year recurrence-free survivals of patients with residual pT0/pTa/pCis, pT1 and pT2 were 100%, 85% and 75%, respectively. The 5-year cancer-specific survival rates for the same patient cohorts were 100%, 93%, and 81%, respectively. In multivariable analyses, the effect of residual stage <pT2 at RC achieved independent predictor status for recurrence (adjusted HR 0.20; p = 0.002), as well as for cancer-specific survival (adjusted HR: 0.24; p = 0.02). Initial T1 patients who were pT2 at RC did not have statistically different outcomes compared to initial T2 followed by pT2 at RC. Conclusions: Patients with pT2N0 TCC of the urinary bladder with residual non-muscle invasive disease at RC have significantly better long-term outcomes compared to residual muscle-invasive disease. With further validation, these data may facilitate the risk-stratification of patients with pT2N0 disease and enable the selection of high-risk patients for trials of adjuvant therapy.

The limitations of the biomarker prostate-specific antigen (PSA) necessitate the pursuit of biomarkers capable of better identifying high-risk prostate cancer (PC) patients in order to improve their therapeutic management and outcomes. Aggressive prostate tumors characteristically exhibit high rates of glycolysis and lipogenesis. Glycerol 3-phosphate phosphatase (G3PP), also known as phosphoglycolate phosphatase (PGP), is a recently identified mammalian enzyme, shown to play a role in the regulation of glucose metabolism, lipogenesis, lipolysis, and cellular nutrient-excess detoxification. We hypothesized that G3PP may relieve metabolic stress in cancer cells and assessed the association of its expression with PC patient prognosis. Using immunohistochemical staining, we assessed the epithelial expression of G3PP in two different radical prostatectomy (RP) cohorts with a total of 1797 patients, for whom information on biochemical recurrence (BCR), metastasis, and mortality was available. The association between biomarker expression, biochemical recurrence (BCR), bone metastasis, and prostate cancer-specific survival was established using log-rank and multivariable Cox regression analyses. High expression of G3PP in PC epithelial cells is associated with an increased risk of BCR, bone metastasis, and PC-specific mortality. Multivariate analysis revealed high G3PP expression in tumors as an independent predictor of BCR and bone metastasis development. High G3PP expression in tumors from patients eligible for prostatectomies is a new and independent prognostic biomarker of poor prognosis and aggressive PC for recurrence, bone metastasis, and mortality.

Abstract Background Stage IV colorectal cancer (CRC) patients are heterogeneous with distinctive clinicopathologic features and prognosis. Radical resection of primary tumor and distant metastases is associated with improved survival outcomes in metastatic CRC. The value of palliative primary tumor resection is controversial. The present study explored which subgroups benefited more from primary tumor resection in metastatic CRC. Methods Between 2004 and 2015, patients with metastatic CRC were identified using the surveillance, epidemiology, and end results (SEER) database. Uni- and multivariable Cox regression analysis were performed to identify factors associated with decreased cancer-specific mortality. The subgroups were divided based on the independent prognostic factors. Results Age, marital status, race, serum CEA, histologic type, differentiation, tumor location, surgery of primary or metastatic lesion, site of metastases, number of metastatic sites, chemotherapy and radiotherapy were identified as independent prognostic factors. Patients with non-white race, normal serum CEA, non-signet ring cell carcinoma, well or moderate differentiation, surgery of metastases, isolated liver metastasis, single metastasis, receiving chemotherapy or radiotherapy presented more survival benefit from primary tumor resection. Conclusion Subgroup of metastatic CRC optimizes decision-making and selected patients will benefit more from primary tumor resection.

We aimed to assess the survival benefits of primary tumor resection (PTR) followed by chemotherapy in patients with asymptomatic stage IV colorectal cancer with asymptomatic, synchronous, unresectable metastases compared to those of upfront chemotherapy alone. This was an open-label, prospective, randomized controlled trial (ClnicalTrials.gov Identifier: NCT01978249). From May 2013 to April 2016, 48 patients (PTR, n = 26; upfront chemotherapy, n = 22) diagnosed with asymptomatic colorectal cancer with unresectable metastases in 12 tertiary hospitals were randomized (1:1). The primary endpoint was two-year overall survival. The secondary endpoints were primary tumor-related complications, PTR-related complications, and rate of conversion to resectable status. The two-year cancer-specific survival was significantly higher in the PTR group than in the upfront chemotherapy group (72.3% vs. 47.1%; p = 0.049). However, the two-year overall survival rate was not significantly different between the PTR and upfront chemotherapy groups (69.5% vs. 44.8%, p = 0.058). The primary tumor-related complication rate was 22.7%. The PTR-related complication rate was 19.2%, with a major complication rate of 3.8%. The rates of conversion to resectable status were 15.3% and 18.2% in the PTR and upfront chemotherapy groups. While PTR followed by chemotherapy resulted in better two-year cancer-specific survival than upfront chemotherapy, the improvement in the two-year overall survival was not significant.

Abstract Background: The HCT-CI is a recently developed comorbidity score which has been adapted to hematopoietic stem cell transplantation, and identified 3 risk groups with increased non-relapse mortality (NRM) and lower overall survival (OS) (Blood2005;106:2912). We determined the HCT-CI score in a cohort of patients who underwent myeloablative MUD transplantation in a single arm, institutional trial assessing the efficacy of a combination of cyclosporine, methotrexate and prednisone for GVHD prophylaxis. Methods: The analysis included all patients undergoing MUD transplant from 1996–2006 who received GVHD prophylaxis with cyclosporine 2 mg/kg iv BID from day −2, methotrexate 15 mg/m2 iv on day +1 and 10 mg/m2 iv on days +3 and +6, and methylprednisolone 0.25 mg/kg iv BID beginning on day +7 and tapering from day +28. Patients were stratified by disease risk per CIBMTR classification. The comorbidities were obtained by retrospective chart review and scored according to the HCT-CI score. Results: 150 patients (median age 40) received the 3 drug-regimen, including 38% with low-, 34% with intermediate- and 28% with high-risk disease. Diagnoses included acute leukemia in 50%, MDS in 12%, CML in 15%, lymphoma in 18%, and multiple myeloma in 3.0%. Conditioning regimens included Cy-TBI in 64% and Bu-Cy in 21%. Source of stem cells was PBSC in 47.3% and marrow in 50.7%. HCT-CI scores of 0, 1–2 or ≥3 were found in 17%, 30% and 53% of patients evaluated. The majority of comorbidities were pulmonary (72%). With a median follow-up of 46 weeks, day 100 and 5-year OS were 82.7 and 33%, with a 23% and 50.4% cumulative incidence of NRM. Five year relapse-related mortality was 15.8%. Although higher HCT-CI scores were associated with increased NRM and decreased OS, no statistically significant differences were detected when using the published HCT-CI grouping of 0, 1–2 and ≥3. Unadjusted hazard ratio (HR) for inferior survival were 0.9 (CI 0.47–1.85, P=.79) and 1.65 (CI 0.885–3.090, P=.11) for scores 1–2 and ≥3, respectively. We then determined an alternate prognostic model based on 2 groups. Statistical modeling separated patients with a score of 0–3 (n=97, 64%) and ≥4 (n=53, 35.6%), with a 3 month and 5 year OS of 84% and 45% versus 52% and 10%, respectively (P&lt;.0001). Cumulative incidence of day 100 and 5-year NRM was 16% and 38% versus 43% and 73%, respectively. Unadjusted HR for inferior survival was 2.77 (CI 1.816–4.225, P&lt;.0001) for a score of ≥4. By multivariate analysis, only the HCT-CI score (P&lt;.0001) and the disease risk per CIBMTR (P=.0058) were predictive of OS and NRM, but not age, CMV positivity, sex- or HLA-mismatch, or regimen. Conclusions: While our data confirm that the HCT-CI score is predictive of NRM and OS in a high-risk MUD transplant cohort, we were unable to detect statistically significant differences between the 3 risk groups defined in the original score. A modified 2-group scoring system readily stratified the patient population into low-risk and high-risk risk groups with scores of 0–3 and ≥4, respectively, that was predictive of OS and NRM. This simplified, 2-tiered scoring system will have utility in clinical decision-making and in defining patient populations eligible for clinical trials. Additional single and multi-institutional analyses will ultimately determine the optimal applications of the HCT-CI score.

SummaryThe Asian population is thought to have a low risk of venous thromboembolism (VTE), but the epidemiology of VTE in cancer patients remains unclear. The National Health Insurance Research Database of Taiwan was used to find hospitalised patients newly-diagnosed with cancer to determine the incidence of VTE in cancer patients and to identify the risk factors for VTE. Between 1997 and 2005, 497,180 cancer patients were identified. During a median follow-up of 21.3 months (range 0–119.9 months), 5,296 patients developed VTE. The estimated incidence was 185 events per 100,000 person-years. Patients with a prior history of VTE and female patients between the ages of 40 and 80 carried high risk of VTE. The rate of VTE was relatively high in patients with myeloma, prostate cancer, lung cancer, gynaecologic cancers, sarcoma, and metastasis of unknown origin. We developed a risk-stratification scoring system to divide the cancer patients into four discrete risk groups (very low risk, low risk, intermediate, and high risk). The incidence of VTE in each group was 0.5%, 0.9%, 1.5%, and 8.7%, respectively (p < 0.001). This scoring system was validated in a separate patient cohort. In conclusion, VTE is a distinct burden for cancer patients in Taiwan. The risk scoring system could prove helpful in decision-making concerning thromboprophylaxis in cancer patients.Note: The results of this paper were presented as an Asian-Pacific Scholarship Award at the 23rd Congress of the International Society on Thrombosis and Haemostasis, Kyoto, Japan, 23–28 July 2011.

Aim. To assess the prevalence, severity and prognostic value of renal dysfunction (RD) in patients with pulmonary embolism (PE) of the Russian population, as well as to determine the RD significance as a marker that improves the predictive ability of current risk stratification systems.Material and methods. From April 2018 to April 2019, patients hospitalized due to PE were sequentially included in the Russian multicenter observational prospective registry SIRENA. RD was diagnosed at a glomerular filtration rate (GFR) <60 ml/ min/1,73 m2. Risk of early (hospital or 30-day) death was stratified in accordance with the current 2019 ESC Clinical Guidelines. During the study, we analyzed inpatient mortality and complication rate.Results. A total of 604 patients (men, 293 (49%); women, 311 (51%)) were in the study. RD was detected in 320 (53%) patients, while severe dysfunction — in 63 (10%) ones. In addition, 71 (12%) patients had high death risk, 364 (61%) — intermediate, 164 (27%) — low. During hospitalization, 107 (18%) patients died, including 32% from the high-risk group, 20% — moderate, and 7% — low. RD in the deceased patients was diagnosed more often, while GFR <50 ml/min/1,73 m2 reliably predicted hospital mortality (sensitivity, 67%; specificity, 72%; AUC=0,72; p<0,001). In patients with simplified Pulmonary Embolism Severity Index (sPESI) of 0 and ≥ 1, the presence of RD led to at least a 2-fold increase in mortality. Multivariate Cox regression revealed that RD is a predictor of in-hospital mortality (hazard ratio (HR), 3,41; 95% confidence interval (CI): 2,15-5,41; p<0,001), regardless of the presence of death risk reclassifies, such as high troponin (HR, 1,31; 95% CI: 0,80-2,14; p=0,28) and right ventricular dysfunction (HR, 1,23; 95% CI: 0,74-2,04; p=0,42).Conclusion. In patients with PE of the Russian population, there is a high incidence of RD, which is diagnosed in every second patient and is severe in 10% of cases. The presence of RD is associated with a significant increase in in-hospital mortality, while the risk of death increases with a decrease in GFR. The addition of RD, considered as a decrease in the estimated GFR <60 ml/min/1,73 m2, to the sPESI improves risk stratification and allows identification of patients at high risk of in-hospital death.

Colorectal cancer (CRC) has the characteristics of high morbidity and mortality. LncRNA not only participates in the progression of CRC through genes and transcription levels, but also regulates the tumor microenvironment and leads to the malignant phenotype of tumors. Therefore, we identified immune-related LncRNAs for the construction of clinical prognostic model. We searched The Cancer Genome Atlas (TCGA) database for original data. Then we identified differentially expressed irlncRNA (DEirlncRNA), which was paired and verified subsequently. Next, univariate analysis, Lasso and Cox regression analysis were performed on the DEirlncRNA pair. The ROC curve of the signature was drawn, and the optimal cut-off value was found. Then the cohort was divided into a high-risk and a low-risk group. Finally, we re-evaluated the signature from different perspectives. A total of 16 pairs of DEirlncRNA were included in the construction of the model. After regrouping according to the cut-off value of 1.275, the high-risk group showed adverse survival outcomes, progressive clinicopathological features, specific immune cell infiltration status, and high sensitivity to some chemotherapy drugs. In conclusion, we constructed a signature composed of immune-related LncRNA pair with no requirement of the specific expression level of genes, which shows promising clinical predictive value in CRC patients.

Abstract Background The esophageal cancer patients with bone metastasis present with an extremely poor prognosis. The aim of this study was to establish a comprehensive insight into whether chemotherapy is justifiably being prescribed to esophageal cancer patients with bone metastasis. Methods A population-based retrospective study was conducted with data from the Surveillance, Epidemiology, and End Results (SEER) national database. By performing 1:1 paired match propensity score matching (PSM), we minimized the baseline discrepancies between groups. Univariate and multivariate Cox regression analyses were used to identify factors associated with survival. Kaplan–Meier survival curves were used to assess the effects of chemotherapy on survival. Results The final PSM cohort consisted of 730 patients, including 365 patients in the chemotherapy group and 365 patients in the non-chemotherapy group. There was a significant difference in overall survival (OS, p < 0.001) and cancer-specific survival (CSS, p < 0.001) between the two groups. The median OS time for the chemotherapy group was 9.8 (95% CI: 8.5–11.2) months, and it was decreased to 2.3 (95% CI 1.9–2.7) months in the non-chemotherapy group. Multivariate analysis confirmed that chemotherapy was an independent prognostic factor for OS (p < 0.001) and CSS (p < 0.001). Kaplan–Meier survival analysis suggested that chemotherapy could significantly improve OS (p < 0.001) and CSS (p < 0.001) both in squamous cell carcinoma or adenocarcinoma subgroup. However, there was no significant difference in both OS (p = 0.291) and CSS (p = 0.651) between the two groups for stage Ⅰ esophageal carcinoma. Conclusion Chemotherapy significantly improved OS and CSS in esophageal cancer patients with bone metastasis. However, chemotherapy might not improve the prognosis of grade I esophageal cancer.
