Abstract Background Only few studies have been evaluated the clinical characteristics and prognosis of hepatocellular carcinoma in young patients. The purpose of this study is to identify prognostic factors and develop an efficient and practical nomogram to predict cancer-specific survival in young patients with hepatocellular carcinoma.Methods Four-hundred-and-forty-one young patients with hepatocellular carcinoma who had undergone surgery from 2004-2015 were selected from the Surveillance, Epidemiology, and End Results database. The competing risk model, Lasso and Cox regression were used to screen prognostic factors for cancer-specific survival, and a prognostic nomogram was established using these factors. Thirty-nine young patients with hepatocellular carcinoma from the National Cancer Center, Cancer Hospital, Chinese Academy of Medical Science were used to validate our model. To further evaluate the predictive performance of our model, the concordance index was calculated and the calibration curves were drawn. The clinical usefulness was evaluated by decision curve analysis(DCA). Finally, all patients were grouped by our nomogram. The survival of different risk groups was analyzed using the Kaplan-Meier method, and the differences among survival curves were compared by the log-rank test.Results The median survival times of the Surveillance, Epidemiology, and End Results training group and the external National Cancer Center validation group were 41 and 52 months, respectively. Histological grade, tumor size, Alpha-fetoprotein, T stage, and M stage were selected as independent factors for cancer-specific survival, and a prognostic nomogram was established. The concordance indices of the training and external validation groups were 0.76 (95% CI, 0.72 to 0.80) and 0.92 (se=0.085), respectively. The calibration plots showed good agreement. Decision curve analysis revealed that our nomogram resulted in a better clinical net benefit than the AJCC 7th edition and Barcelona Clinic Liver Cancer staging systems. Patients were divided into two risk groups according to the cut-off value of 125 of the total points from our nomogram. Kaplan-Meier plots for cancer-specific survival were performed using the log-rank test, the p-value of which was <0.001.Conclusions The practical nomogram resulted in a more-accurate prognostic prediction for young hepatocellular carcinoma patients after curative liver resection.

Right Posterior Sectionectomy

Background and Aims: This study was designed to analyze the feasibility of laparoscopic right posterior sectionectomy compared to laparoscopic right hemihepatectomy in patients with hepatocellular carcinoma located in the posterior segments. Material and Methods: The study included patients who underwent either laparoscopic right posterior sectionectomy or laparoscopic right hemihepatectomy for hepatocellular carcinoma located in segment 6 or 7 from January 2009 to December 2016 at Samsung Medical Center. After 1:1 propensity score matching, patient baseline characteristics and operative and postoperative outcomes were compared between the two groups. Disease-free survival and overall survival were compared using Kaplan–Meier log-rank test. Results: Among 61 patients with laparoscopic right posterior sectionectomy and 37 patients with laparoscopic right hemihepatectomy, 30 patients from each group were analyzed after propensity score matching. After matching, baseline characteristics of the two groups were similar including tumor size (3.4 ± 1.2 cm in laparoscopic right posterior sectionectomy vs 3.7 ± 2.1 cm in laparoscopic right hemihepatectomy, P = 0.483); differences were significant before matching (3.1 ± 1.3 cm in laparoscopic right posterior sectionectomy vs 4.3 ± 2.7 cm in laparoscopic right hemihepatectomy, P = 0.035). No significant differences were observed in operative and postoperative data except for free margin size (1.04 ± 0.71 cm in laparoscopic right posterior sectionectomy vs 2.95 ± 1.75 cm in laparoscopic right hemihepatectomy, P < 0.001). Disease-free survival (5-year survival: 38.0% in laparoscopic right posterior sectionectomy vs 47.0% in laparoscopic right hemihepatectomy, P = 0.510) and overall survival (5-year survival: 92.7% in laparoscopic right posterior sectionectomy vs 89.6% in laparoscopic right hemihepatectomy, P = 0.593) did not differ between the groups based on Kaplan–Meier log-rank test. Conclusion: For hepatocellular carcinoma in the posterior segments, laparoscopic right posterior sectionectomy was feasible compared to laparoscopic right hemihepatectomy when performed by experienced laparoscopic surgeons.

Abstract Objectives: This retrospective study investigated the predictive value of the Controlling Nutritional Status (CONUT) score in patients with intermediate-stage hepatocellular carcinoma (HCC) who received transarterial chemoembolization (TACE). Nomograms were developed to predict progression-free and overall survival (PFS, OS). Methods: The medical data of 228 patients with HCC and treated with TACE were collected. The patients were apportioned to 2 groups according to CONUT score: low or high (<4, ≥4). Univariate and multivariate analyses were performed using Cox regression for OS and PFS. OS and PFS were estimated by the Kaplan-Meier curve and compared with the log-rank test. Nomograms were constructed to predict patient OS and PFS. The nomograms were evaluated for accuracy, discrimination, and efficiency. Results: The cut-off value of CONUT score was 4. The higher the CONUT score, the worse the survival; Kaplan-Meier curves showed significant differences in OS and PFS between the low and high CONUT score groups (P = 0.033, 0.047). The nomograms including CONUT, based on the prognostic factors determined by the univariate and multivariate analyses, to predict survival in HCC after TACE were generated. Conclusions: The CONUT score is an important prognostic factor for both OS and PFS for patients with intermediate HCC who underwent TACE. The cut-off value of the CONUT score was 4. A high CONUT score suggests poor survival outcomes. Nomograms generated based on the CONUT score were good models to predict patient OS and PFS.

Abstract Background Epithelial ovarian cancer (EOC) is the majority ovarian cancer (OC) type with a poor prognosis. This present study aimed to investigate potential prognostic factors including albumin-to-fibrinogen ratio (AFR) for advanced EOC patients with neoadjuvant chemotherapy (NAC) followed by debulking surgery. Methods A total of 313 advanced EOC patients with NAC followed by debulking surgery from 2010 to 2017 were enrolled. The predictive value of AFR for the overall survival (OS) was evaluated by receiver operating characteristic (ROC) curve analysis. The univariate and multivariate Cox proportional hazards regression analyses were applied to investigate prognostic factors for advanced EOC patients. The association between preoperative AFR and progression free survival (PFS) or OS was determined via the Kaplan–Meier method using log-rank test. Results The ROC curve analysis showed that the cutoff value of preoperative AFR in predicting OS was determined to be 7.78 with an area under the curve (AUC) of 0.773 (P < 0.001). Chemotherapy resistance, preoperative CA125 and AFR were independent risk factors for PFS in advanced EOC patients. Furthermore, chemotherapy resistance, residual tumor and AFR were significant risk factors for OS by multivariate Cox analysis. A low preoperative AFR (≤7.78) was significantly associated with a worse PFS and OS via the Kaplan–Meier method by log-rank test (P < 0.001). Conclusions A low preoperative AFR was an independent risk factor for PFS and OS in advanced EOC patients with NAC followed by debulking surgery.

AbstractAlthough the occurrence of tumour deposits (TDs) without metastatic lymph nodes (mLNs) is classified as “N1c” in the 8th TNM staging system for colorectal cancer (CRC), the prognostic significance of the TD count is still controversial. A total of 39155 CRC patients were collected from the Surveillance, Epidemiology, and End Results (SEER) database. The potential associations between baseline characteristics and TD status were evaluated using the χ2 test. Cancer-specific survival (CSS) rates were calculated by using the Kaplan-Meier method, and CSS comparisons were performed by using the log-rank test. The results showed that TD count was an important prognostic factor and that the number of TDs was negatively correlated with the prognosis of CRC patients. We found that the prognostic value of one TD is equivalent to that of two mLNs based on the comparison of CSS rates. Accordingly, we proposed a novel N staging system by integrating the TD count into the N category with the ratio of TDs to mLNs being 1:2. There were no prognostic differences in patients with or without TDs in each novel N category. Weighing one TD as two mLNs in this novel TNM staging system is superior to the “N1c” classification in the 8th TNM staging system in evaluating the prognosis of CRC patients.

<b><i>Background &amp; Aims:</i></b> Intermediate hepatocellular carcinoma (HCC) treatment has become complicated due to the development of various molecular-targeted agents (MTAs). We aimed to determine whether the administration of MTAs in patients with intermediate-stage HCC contributed to the prevention of progression to an advanced stage. <b><i>Methods:</i></b> We enrolled and retrospectively examined 289 patients with Child-Pugh class A who had been diagnosed with intermediate-stage HCC and underwent initial trans-arterial chemoembolization (TACE). Patients were classified into 2 groups: a group in which MTAs were administered to patients whose condition was refractory to TACE (<i>n</i> = 65) and a group in which MTAs were not administered (<i>n</i> = 65) at intermediate-stage HCC after propensity score matching (PSM). Time to stage progression (TTSP) and overall survival (OS) were calculated using the Kaplan-Meier method and analyzed using a log-rank test after PSM. <b><i>Results:</i></b> TTSP and OS of the group with MTA administration were significantly longer than those of the group without MTA administration (TTSP: 36.4 vs. 17.9 months, <i>p</i> &#x3c; 0.001; median survival time [MST]: 44.6 vs. 26.6 months, <i>p</i> = 0.001). Within the up-to-seven criteria and administration of MTAs at the intermediate-stage HCC were identified as independent factors for TTSP and OS in the multivariate analysis. TTSP and OS in the era of the multi-MTA group were significantly longer than those in the era of the mono-MTA group (TTSP: 44.8 vs. 27.4 months, <i>p</i> = 0.01; MST: 53.4 vs. 33.3 months, <i>p</i> = 0.01). <b><i>Conclusion:</i></b> The administration of MTAs in patients with intermediate-stage HCC contributes to the prevention of stage progression and prolongs OS.

Oncological Patients

Background: Data describing the characteristics, treatment, and survival of oncological patients referred to PCS remains scarce. Aim: To establish the characteristics of oncological patients referred to PCS, including their profile, treatment, and survival within a 7-year period. Design: Retrospective review of medical records. Clinical variables such as treatment and dates were included. Ji2 or Wilcoxon tests were used accordingly; Kaplan-Meier and log rank test were used to estimate survival. Setting/Participants: Consecutive oncological patients diagnosed between 2012 and 2018 sent to PCS were included. Results: We studied 5,631 patients, 58% female and 59% at advanced stage. Median age was 59 years, with 6 years or less of formal education and low monthly income ($152.4 USD). Neoplasms included breast (12%), stomach (12%), colorectal (10%) and cervical cancer (9%). Median referral time was 5.1 months; pain was the main reason for referral. Morphine was the most prescribed opioid with 47%. Median overall survival was 3.1 months. Conclusions: Morphine remains the paradigm of treatment making necessary to emphasize information on its optimal use. Additional measures such as education for cancer prevention and early referral to PCS are vital to improve survival and quality of life.

Chirurgische Entfernung

Die komplette chirurgische Entfernung von Lebermetastasen bietet Patienten nach kolorektalem Karzinom die einzige kurative Chance. Es gibt jedoch eine, anscheinend unbegrenzte, Anzahl an Parametern, die die Prognose dieser Patienten bestimmen und damit den Sinn dieser Therapie vorhersagen können. Zu den am häufigsten diskutierten und am einfachsten zu bestimmenden Parametern gehört die Anzahl der Metastasen. Ziel dieser Studie war es daher die Wertigkeit dieses Parameters in der Literatur zu reflektieren und unsere eigenen Patientendaten zu evaluieren. Insgesamt konnte von 302 Patienten ein komplettes Follow-up erhoben werden. Die gebildeten Patientengruppen wurden mit Hilfe einer Kaplan Meier Analyse und konsekutivem log rank Test untersucht. Die Literatur wurde bis Dezember 1998 revidiert. Die Anzahl der Metastasen bestätigte sich als ein prognostisches Kriterium. Lagen drei oder mehr Metastasen vor, so war nicht nur die Wahrscheinlichkeit einer R0 Resektion deutlich geringer (17.8% versus 67.2%) sondern auch das Überleben der Patienten nach einer R0 Resektion tendenziell unwahrscheinlicher. Das 5-Jahres Überleben betrug bei > 2 Metastasen 9% bei > 2 Metastasen 36%. Das 10-Jahres Überleben beträgt bislang bei > 2 Metastasen 0% bei > 2 Metastasen 18% (p < 0.07). Die Anzahl der Metastasen spielt in der Prognose der Patienten mit kolorektalen Lebermetastasen eine Rolle. Selbst bei mehr als vier Metastasen ist jedoch gelegentlich eine R0 Resektion möglich. In diesen Fällen kann der Patient auch langfristig von einer Operation profitieren. Das wichtigere Kriterium einer onkologisch sinnvollen Resektabilität ist die Frage ob technisch und funktionell eine R0 Resektion durchführbar ist. Ist das der Fall, so sollte auch einem Patienten mit mehreren Metastasen die einzige kurative Chance einer Resektion nicht vorenthalten bleiben.

Abstract Background The prognostic roles of three lymph node classifications, number of positive lymph nodes (NPLN), log odds of positive lymph nodes (LODDS), and lymph node ratio (LNR) in lung adenocarcinoma are unclear. We aim to find the classification with the strongest predictive power and combine it with the American Joint Committee on Cancer (AJCC) 8th TNM stage to establish an optimal prognostic nomogram. Methods 25,005 patients with T1-4N0–2M0 lung adenocarcinoma after surgery between 2004 to 2016 from the Surveillance, Epidemiology, and End Results database were included. The study cohort was divided into training cohort (13,551 patients) and external validation cohort (11,454 patients) according to different geographic region. Univariate and multivariate Cox regression analyses were performed on the training cohort to evaluate the predictive performance of NPLN (Model 1), LODDS (Model 2), LNR (Model 3) or LODDS+LNR (Model 4) respectively for cancer-specific survival and overall survival. Likelihood-ratio χ2 test, Akaike Information Criterion, Harrell concordance index, integrated discrimination improvement (IDI) and net reclassification improvement (NRI) were used to evaluate the predictive performance of the models. Nomograms were established according to the optimal models. They’re put into internal validation using bootstrapping technique and external validation using calibration curves. Nomograms were compared with AJCC 8th TNM stage using decision curve analysis. Results NPLN, LODDS and LNR were independent prognostic factors for cancer-specific survival and overall survival. LODDS+LNR (Model 4) demonstrated the highest Likelihood-ratio χ2 test, highest Harrell concordance index, and lowest Akaike Information Criterion, and IDI and NRI values suggested Model 4 had better prediction accuracy than other models. Internal and external validations showed that the nomograms combining TNM stage with LODDS+LNR were convincingly precise. Decision curve analysis suggested the nomograms performed better than AJCC 8th TNM stage in clinical practicability. Conclusions We constructed online nomograms for cancer-specific survival and overall survival of lung adenocarcinoma patients after surgery, which may facilitate doctors to provide highly individualized therapy.

Abstract Objective Sepsis is a major cause of mortality for critically ill patients. This study aimed to determine whether presepsin values can predict mortality in patients with sepsis. Results Receiver operating characteristic (ROC) curve analysis, Log-rank test, and multivariate analysis identified presepsin values and Prognostic Nutritional Index as predictors of mortality in sepsis patients. Presepsin value on Day 1 was a predictor of early mortality, i.e., death within 7 days of ICU admission; ROC curve analysis revealed an AUC of 0.84, sensitivity of 89%, and specificity of 77%; and multivariate analysis showed an OR of 1.0007, with a 95%CI of 1.0001–1.0013 (p = 0.0320).

Purpose The current European LeukemiaNet (ELN) recommendations for acute myeloid leukemia (AML) propose a new risk reporting system, integrating molecular and cytogenetic factors and subdividing the large heterogenous group of intermediate-risk patients into intermediate-I (IR-I) and intermediate-II (IR-II). We assessed the prognostic value of the new risk classification in a large cohort of patients. Patients and Methods Complete data for classification were available for 1,557 of 1,862 patients treated in the AML96 trial. Patients were assigned to the proposed genetic groups from the ELN recommendations, and survival analyses were performed using the Kaplan-Meier method and log-rank test for significance testing. Results The median age of all patients was 67 years. With a median follow-up of 8.3 years, significant differences between all risk categories were observed in patients age ≤ 60 years regarding the time to relapse, relapse-free survival, and overall survival (OS). Patients in the IR-II group had a better prognosis than patients in the IR-I group. The median OS times in young patients with favorable risk (FR), IR-I, IR-II, and adverse risk (AR) were 5.3, 1.1, 1.6, and 0.5 years, respectively. Separate analyses in the age group older than 60 years revealed significant differences between FR, AR, and IR as a whole, but not between IR-I and IR-II. Conclusion In younger patients with AML, the ELN classification seems to be the best available framework for prognostic estimations to date. Caution is advised concerning its use for prospective treatment allocation before it has been prospectively validated. In elderly patients, alternative prognostic factors are desirable for further risk stratification of IR.
