Objectives The clinical presentations of essential thrombocythemia (ET) may be quite similar to early/prefibrotic primary myelofibrosis (pre-PMF), especially in pre-PMF presenting with thrombocytosis (pre–PMF-T), but may be associated with a different outcome. It is very important to distinguish these two entities. The aim of this study was to address the clinical and prognostic relevance of distinguishing pre–PMF-T from ET. Methods All patients, including 258 with ET and 105 with pre–PMF-T, received JAK2V617F, MPL (exon 10), and CALR (exon 9) mutation analysis and allele burden measurement for JAK2V617F and CALR mutants. Results Patients with pre–PMF-T had an older age and higher leukocyte and platelet counts but lower hemoglobin levels than patients with ET. Patients with pre–PMF-T had a shorter overall, leukemia-free, and thrombosis-free survival compared with patients with ET. Patients with ET had a higher rate of cerebral ischemic stroke, whereas patients with pre–PMF-T tended to have splanchnic vein thrombosis. The frequencies of JAK2V617F, CALR, and MPL mutations and CALR allele burden were no different, but JAK2V617F allele burden was significantly higher in pre–PMF-T. Patients with pre–PMF-T with the JAK2V617F mutation had an inferior overall survival and thrombosis-free survival, whereas the status of driver gene mutations did not influence the outcomes of patients with ET. Conclusions ET and pre–PMF-T were two distinct disease entities and exhibited different clinical phenotype, genotype, and outcomes.

Background/Aim: Neoadjuvant concurrent chemoradiotherapy (CCRT) for esophageal cancer is often overwhelming due to its toxic effects. This study aimed to establish a prognostic indicator based on pretreatment albumin and neutrophil-to-lymphocyte (NLR) ratio score (ANS) in comparison to the Prognostic Nutritional Index (PNI) in patients with esophageal cancer. Patients and Methods: A total of 123 patients who received neoadjuvant CCRT for esophageal cancer were prospectively and consecutively recruited between August 2016 and December 2017 from three medical institutes in Taiwan. Patients were assigned to ANS 0, 1, and 2 groups based on their pretreatment albumin and NLR values. ANS and PNI performances were compared for prediction of survival outcome. Results: Compared with ANS 0 (39 patients) and ANS 1 (51 patients), ANS 2 (33 patients) cases showed worse overall survival (hazard ratio=2.96; 95% confidence interval=1.45-6.05; log-rank p=0.003; hazard ratio=3.79; 95% confidence interval=1.79-8.02, p

Locked nucleic acid quantitative Real-Time PCR (LNA-qPCR) for IDH1/2 mutations in AML measurable residual disease (MRD) detection is rarely reported. LNA-qPCR was applied to quantify IDH1/2 mutants MRD kinetics in bone marrow from 88 IDH1/2-mutated AML patients, and correlated with NPM1-MRD, clinical characteristics, and outcomes. The median normalized copy number (NCN) of IDH1/2 mutants decreased significantly from 53,228 (range 87–980,686)/ALB × 106 at diagnosis to 773 (range 1.5–103,600)/ALB × 106 at first complete remission (CR). IDH1/2 LNA-qPCR MRD was concordant with remission status or NPM1-MRD in 79.5% (70/88) of patients. Younger patients and patients with FLT3 mutations had higher concordance. The Spearman correlation coefficient (rs) and concordance rate between the log reduction of IDH1/2 LNA-qPCR and NPM1-MRD were 0.68 and 81% (K = 0.63, 95% CI 0.50–0.74), respectively. IDH1/2-MRD > 2 log reduction at first CR predicted significantly better relapse-free survival (3-year RFS rates 52.9% vs. 31.9%, p = 0.007) and cumulative incidence of relapse (3-year CIR rates 44.5% vs. 64.5%, p = 0.012) compared to IDH1/2-MRD ≤ 2 log reduction. IDH1/2-MRD > 2 log reduction during consolidation is also associated with a significantly lower CIR rate than IDH1/2-MRD ≤ 2 log reduction (3-year CIR rates 42.3% vs. 68.8%, p = 0.019). LNA-qPCR for IDH1/2 mutation is a potential MRD technique to predict relapse in IDH1/2-mutated AML patients, especially for those with IDH1/2 MRD > 2 log reduction at first CR or a concurrent FLT3 mutation.

Background: With the rapid growth of the elderly population and the increasing incidence of cancer, an increasing number of geriatric patients are receiving cancer treatment, making the selection of appropriate treatment an important issue. Increasing studies have confirmed that frailty can predict adverse outcomes in geriatric patients with cancer after treatment, but local data from Taiwan are lacking. Therefore, this study aimed to investigate the correlation between frailty and chemotherapy-related adverse outcomes in geriatric patients with cancer. Material and Methods: A total of 234 geriatric patients aged ≥65 years with cancer receiving chemotherapy were enrolled during the study period of September 2016 to November 2018. The collected data included: patients’ basic demographics and Comprehensive Geriatric Assessment (CGA) before treatment, chemotherapy-related adverse outcomes, unexpected hospitalizations, and emergency department visits within 3 months of treatment. We investigated the association between frailty and chemotherapy-related adverse outcomes in geriatric patients with cancer using the chi-square test and logistic regression analysis. Results: The prevalence of frailty in geriatric patients with cancer was 58.1%. Age, marital status, main caregiver, cancer type, and Eastern Cooperative Oncology Group performance status, and physical fitness were factors associated with frailty. Frail geriatric patients with cancer were at higher risk of chemotherapy-related adverse outcomes, such as grades 3–4 thrombocytopenia (odds ratio [OR] = 11.13, p = 0.021) and grades 3–4 hyponatremia (OR = 12.03, p = 0.017), than non-frail patients, and they were at increased risk of unexpected hospitalizations (OR = 2.15, p = 0.025) and emergency department visits (OR = 1.99, p = 0.039). Conclusions: Frailty is a common problem in geriatric patients with cancer and significantly impacts chemotherapy-related adverse outcomes. Our findings suggest that geriatric patients with cancer should undergo frail assessment prior to chemotherapy as a reference to guide future treatment decisions.

BACKGROUND/AIM The clinical significance of frailty status on treatment outcome in patients with esophageal cancer (EC) has been seldom explored. This study aimed to evaluate the impact of pretreatment frailty on treatment-related toxicity and survival outcome in patients with EC undergoing concurrent chemoradiotherapy (CCRT). PATIENTS AND METHODS Patients aged ≥20 years and with newly diagnosed locally advanced EC receiving neoadjuvant radiotherapy and concurrent chemotherapy with weekly administration of carboplatin and paclitaxel for 5 weeks were prospectively enrolled. A pretreatment frailty assessment was performed within 7 days before CCRT initiation. The primary endpoint was treatment-related toxicity and complications of CCRT while the secondary endpoint was overall survival. RESULTS A total of 87 patients were enrolled, 41 (47%) and 46 (53%) of whom were allocated in the frail and fit group, respectively. Frail patients had a significantly higher incidence of having at least one severe hematological adverse event (63.4% vs. 19.6%, p

Objectives Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of non-Hodgkin lymphoma with uncommon clinical presentations and poor prognosis. The purpose of this study is to report the clinical features and outcome of IVLBCL in a single institution of Taiwan. Patient and methods Ten patients with IVLBCL diagnosed from June 2006 to January 2018 were retrospectively reviewed. Results The median age was 61 (range 39–88) years. The most common presentation was fever (90%), cytopenia (90%), and confusion (50%). For all patients, the median progression free survival (PFS) and overall survival (OS) were 12.6 (95% confidence interval [CI] 0.0–76.1) and 18.8 (95% CI 0–59.3) months, respectively. Six patients received rituximab combined chemotherapy, and the other one patient was treated with chemotherapy alone. Six of seven (85.7%) patients achieved complete response after chemotherapy. The median PFS and OS for six patients who completed treatment were not reached. Three-year PFS and OS rates were 80% and 75%, respectively. Conclusions Our study showed that patients might achieve durable remission after rituximab-based chemotherapy. The outcome of IVLBCL patients may further improve if early diagnosis and prompt treatment were made.

Background: The palliative prognostic index (PPI) predicts the life expectancy of patients with terminally ill cancer in hospice settings. This study aimed to evaluate PPI as a prognostic tool for predicting the life expectancy of patients with hematological malignancies admitted to the acute ward. Methods: A total of 308 patients with hematological malignancies admitted to the hematological ward at a medical center between January 2016 and December 2017 were consecutively enrolled. PPI was scored within 24 h of admission. All patients were categorized into 3 groups by PPI for comparing survival and in-hospital mortality rates. Results: The median survival times were 38.4, 3.6, and 1.1 months for patients with good, intermediate, and poor prognostic group, respectively. The hazard ratio was 2.31 (95% CI 1.59-3.35, p < 0.001) when comparing the intermediate and good prognosis groups, and 3.90 (95% CI 2.52-6.03, p < 0.001) when comparing the poor and good prognosis groups. Forty-five (14.6%) patients died at discharge; in-hospital mortality rates among the good, intermediate, and poor prognostic groups were 9.0%, 23.4%, and 46.4%, respectively. The adjusted odds ratio for in-hospital mortality was 1.96 (95% CI, 0.80-4.82, p = 0.14) and 5.25 (95% CI, 2.01-13.7, p < 0.001) for patients in the intermediate and poor prognostic groups compared to those in the good prognostic group. Conclusion: PPI is an accurate prognostic tool for predicting survival times and in-hospital mortality rates in patients with hematological malignancies in an acute ward setting. PPI could assist clinicians in discussing end-of-life issues and in referring patients with hematological malignancies to palliative care.

We previously developed a Chang Gung Memorial Hospital (CGMH) model to predict the 1-year postoperative mortality risk in patients with solid cancer undergoing cancer surgery. This study aimed to externally validate the CGMH score for survival outcome and surgical complication prediction in a prospective patient cohort. A total of 345 consecutive patients aged ≥65 years who underwent elective abdominal surgery for cancer treatment were prospectively enrolled. Patients were categorized into the low, intermediate, high, and very high-risk groups according to the CGMH score for comparison. The postoperative 1-year mortality rate was 12.5% in the entire cohort. The postoperative 1-year mortality rates were 0%, 2.2%, 14.0%, and 31.6% among patients in the low, intermediate, high, and very-high risk groups, respectively. The c-statistic of the CGMH model was 0.82 (95% confidence interval [CI], 0.76-0.88) for predicting the 1-year mortality risk. Hazard ratios for overall survival were 3.73 (95% CI, 2.11-6.57; P0.001) and 10.1 (95% CI, 5.84-17.6; P0.001) when comparing the high and very-high risk groups with the low/intermediate risk groups, respectively. Patients in the higher CGMH risk groups had higher risks of adverse surgical outcomes in terms of longer length of hospital stay, major surgical complications, postoperative intensive care unit stay, and in-hospital death. The CGMH model accurately predicted thesurvival probabilityand risk of adverse surgical outcomes in older patients with cancer undergoing elective abdominal surgery. Our study justifies the prospective use of the CGMH model for survival outcome and safety profile predictionfor cancer surgery in older patients.

Postoperative delirium (POD) is a common surgical complication in elderly patients. As frailty is a relatively novel concept, its clinical significance for POD has seldom been examined. This study aimed to investigate the association between frailty and POD in aged cancer patients undergoing elective abdominal surgery in Taiwan.We prospectively enrolled 345 consecutive patients aged ≥65 years with newly diagnosed cancer who underwent elective abdominal surgery between 2016 and 2018. Frailty assessment was performed using the Comprehensive Geriatric Assessment (CGA). POD was assessed daily using the Confusion Assessment Method from postoperative day 1 until discharge. Patients were allocated into fit and frail groups.POD occurred in 19 (5.5%) of 345 patients. POD incidence was 1.6%, 3.1%, 4.8%, 11.5%, and 10.0% in patients with 0, 1, 2, 3, and 4+ frail conditions, respectively, which presented a positive linear correlation among patients with an increased number of frail conditions and POD incidence. Based on CGA, 159 (46.1%) and 186 (53.9%) patients were allocated to fit and frail groups, respectively. POD incidence was 2.5% and 8.1% for the fit and frail groups, respectively. Frailty status was an independent risk factor for POD occurrence in multivariate analysis.Our study identified frailty as an independent risk factor for POD in aged Taiwanese cancer patients undergoing elective abdominal surgery. Given the high prevalence of frailty among older cancer patients, preoperative assessment is important to identify high risk of POD and to improve the quality of postoperative care.

BACKGROUND/AIM Cisplatin with 5-fluouracil (Cis/5Fu) and paclitaxel with carboplatin (Pac/Car) are common regimens used in concurrent chemoradiotherapy (CCRT) for patients with locally advanced esophageal cancer (EC). Here, we aimed to compare the survival outcomes and treatment-related toxicities between these regimens in neoadjuvant CCRT in patients with locally advanced EC. PATIENTS AND METHODS One hundred and thirty-six patients with locally advanced EC (98% squamous cell carcinoma) were prospectively recruited between 2016 and 2017 in a non-randomized manner. Patients were categorized into two groups according to the chemotherapeutic agents administered (Pac/Car group, n=87; Cis/5Fu group, n=47) in CCRT to compare the survival outcome and severe adverse event (sAE) incidence. RESULTS Forty-two patients (85.7%) and 80 patients (91.4%) in the Cis/5Fu and Pac/Car groups completed pre-planned CCRT (p=0.26), respectively. The Cis/5Fu group presented a higher incidence of non-hematological sAE than the Pac/Car group (69.45% vs. 51.7%, p=0.049). Patients in the Pac/Car group showed a higher rate of surgical resection than those in the Cis/5Fu group (49.4% vs. 22.4%, p

Purpose This study aimed to identify vulnerable patients with head and neck cancer undergoing concurrent chemoradiation therapy (CCRT) who are susceptible to higher treatment-related adverse effects and have poorer treatment tolerance. This study also aimed to determine whether comprehensive geriatric assessment, developed in the geriatric population, can predict vulnerability to treatment-related adverse events and survival even in nongeriatric patients with head and neck cancer, as well as the prevalence of vulnerability and its effect on toxicities and survival among these patients. Methods and Materials This prospective cohort study examined 461 patients with primary head and neck cancer who underwent definitive CCRT during 2016 to 2017 at 3 medical centers across Taiwan. Vulnerability is defined as susceptibility to cancer- and treatment-related adverse events that result in poor treatment tolerance and unexpected emergent medical needs, such as hospitalization and emergency room visits. Vulnerability was assessed as impairment with ≥2 dimensions on comprehensive geriatric assessment, 7 days before CCRT. The association of vulnerability with treatment-related adverse events and survival was analyzed. Results The prevalence of vulnerability was 22.2%, 27.3%, 30.2%, and 27.9% among patients aged 20 to 34, 35 to 49, 50 to 64, and >65 years, respectively. Survival was poorer in vulnerable patients than in nonvulnerable patients (hazard ratio, 1.97; 95% confidence interval, 1.26-3.07; P = .003). Vulnerable patients showed a higher tendency toward CCRT incompletion (19.5% vs 6.1%, P Conclusions Vulnerability, which is an urgent concern when it presents among patients with head and neck cancer, was independently associated with poorer survival and severe treatment-related complications. Vulnerability assessment should be routinely evaluated in all patients with primary head and neck cancer who are undergoing definitive CCRT, not only in such patients who are geriatric.

Nutritional counseling is frequently overlooked in cancer patients with normal nutritional status. This study aimed to evaluate the impact of nutritional counseling in head and neck cancer (HNC) patients with normal nutritional status prior to concurrent chemoradiotherapy (CCRT). A total of 243 patients with pretreatment normal nutritional status and locally advanced HNC receiving concurrent chemoradiotherapy (CCRT) at three medical centers were enrolled. All patients were retrospectively allocated into the early (≤ 2 weeks, n = 105, 43.2%), late (> 2 weeks, n = 102, 42.0%), and no nutritional counseling groups (n = 36, 14.8%) according to the time interval between the date of CCRT initiation and the first date of nutritional counseling for comparison. The 1-year overall survival rates were 95.0%, 87.5%, and 81.3% in the early, late, and no nutritional counseling groups (p = 0.035), respectively. The median body weight changes at end of CCRT were − 4.8% (range, − 13.3 to 8.7%), − 5.6% (range, − 21.9 to 5.6%), and − 8.6% (range, − 20.3 to 2.4%) in patients in the early, late, and no nutritional counseling groups, respectively. The early termination of chemotherapy rates and the incompletion rates of planned radiotherapy were 1.9% and 1.9%, 2.9%, and 2.0%, 13.9%, and 19.4% in patients in the early, late, and no nutritional counseling groups, respectively. Our findings strongly suggest that while some HNC patients may have pretreatment normal nutritional status, early nutritional counseling is nevertheless essential for the improvement of treatment tolerance and survival outcome.

Objectives Early mortality, defined as death within 120 days after initiated antitumor therapy, is an important issue especially for elder patients with B-cell lymphoma. This study aimed to evaluate the clinical value of comprehensive geriatric assessment (CGA) in early mortality prediction in elderly patients with B-cell lymphoma receiving immunochemotherapy. Methods Seventy-six consecutive patients with newly diagnosed B-cell lymphoma receiving immunochemotherapy from a medical center in Taiwan were prospectively enrolled. Patients were divided into fit (n = 49) and frail (n = 27) groups per pretreatment CGA for early mortality comparison. Results The early mortality rate in our patient cohort was 16% (n = 12): from 6% in patients with no CGA domain impairment to 43% in patients with ≥4 CGA domain impairment. The early mortality rate was 6% and 33% in fit and frail patients (odds ratio, 7.67; 95% CI, 1.86-31.6; P = .005), respectively. Frailty was the significant predictor for early mortality in univariate and multivariate analysis. Conclusion In this study, the number of geriatric domain impairment is positively associated with the early mortality risk in elderly patients with B-cell lymphoma. Therefore, CGA can help clinicians to identify the risk of early mortality in elderly patients and provide alternative treatment.

Conventional treatment for treating primary central nervous system lymphoma (PCNSL) has consisted of either whole-brain radiotherapy (WBRT) or methotrexate (MTX)-based combined modality therapy. However, delayed cognitive sequelae have emerged as a significant debilitating complication in PCNSL patients. A prospective observational case-series study with prospective assessments of neurocognitive functions (NCFs), neuroimaging, and activities of daily living in newly-diagnosed PCNSL patients was undertaken. A battery of neuropsychological measures, used to evaluate NCFs, is composed of ten standardized NCF tests, representing four domains sensitive to disease and treatment effects (executive function, attention, verbal memory, psychomotor speed), and activities of daily living. A total of 15 patients with newly-diagnosed PCNSL were consecutively enrolled in this study. Comparing the NCF scores between the baseline (before WBRT) and post-treatment (after combined chemoradiation therapy) intervals (Mean = 122.33 days, SD = 34.49, range = 77-196), neurobehavioral outcomes consistently remained improving or stable in almost each domain of NCF. Specifically, the scores on Paced Auditory Serial Addition Test-Revised (PASAT-R) were significantly improved between the baseline and post-chemoradiation assessment. Under the multidisciplinary treatment guidelines for treating patients with newly-diagnosed PCNSL, multi-domain NCF become stabilized and even improved after the course of conformal WBRT combined with or without MTX-based chemotherapy.

Introduction: Splenectomy is an important and potentially curative treatment for immune thrombocytopenia (ITP). Laparoscopic splenectomy (LS) has replaced open splenectomy (OS) as the standard approach. The prognostic role of platelet count and the clinical indication of preoperative platelet transfusion are not entirely clear. Methods: We designed a study to explore the prognostic impact of surgical methods, platelet count, and platelet transfusion in a large, single-institute, long-term cohort of ITP patients. Result: In 118 ITP patients, there was no difference between OS and LS in response and surgical complications. The overall response rate was 77% and the complete response (CR) rate was 70%. Patients with a CR had a trend towards a higher baseline platelet count. A stable platelet count 14–28 days after splenectomy was associated with a sustained long-term response. Patients requiring preoperative platelet transfusion had a lower preoperative platelet count and were more likely to need postoperative transfusion of red blood cells and platelets. They also had a lower postoperative platelet count than the nontransfusion group. Relapse-free survival did not differ. Conclusions: Baseline and postoperative platelet counts are apparently associated with the treatment response to splenectomy but the difference did not reach statistical significance. Preoperative platelet transfusion did not overcome the disadvantage of thrombocytopenia and was not recommended when other preparative measures are available.

Frailty is a common clinical syndrome among the elderly; however, it is frequently neglected in patients with hematological malignancies, especially among the Asian population. This study is aimed to evaluate the prevalence and effect of frailty on survival outcomes in elderly Asian patients with B-cell lymphoma.We prospectively enrolled 76 consecutive patients with age ≥ 65 years and newly diagnosed B-cell lymphoma and were receiving immunochemotherapy in a medical center in Taiwan between August 2016 and December 2017. The frailty of all patients was assessed using a comprehensive geriatric assessment (CGA) within 7 days before immunochemotherapy.Twenty-seven patients (36%) were allocated to the frail group based on CGA. With a median follow-up duration of 26.5 (range, 1.7-39.8) months, the 1- and 2-year survival rates were 68% and 58%, respectively, for all group of patients. In patients in the non-frail group, the 1-year and 2-year survival rates were 81% and 71%, respectively, compared to 44% and 33%, respectively, in the frail group (hazard ratio [HR], 3.57, 95% confidence interval [CI], 1.74-7.30; p = 0.001). Age ≥ 75years (adjusted HR 2.57, 95% CI 1.02-6.47, p = 0.045), presence of B-symptoms (adjusted HR 2.43, 95% CI 1.05-5.60, p = 0.038), and frailty (adjusted HR 3.03, 95% CI 1.29-7.11, p = 0.011) were independent prognostic factors in the multivariate analysis.Frailty significantly influenced the survival outcome as an independent prognostic factor in elderly patients with B-cell lymphoma undergoing immunochemotherapy. Pretreatment frailty assessment is critical to assist clinicians and patients with B-cell lymphoma with prognosis prediction and counseling on an appropriate treatment goal.

Background/Aim: Cisplatin with 5-fluouracil (Cis/5Fu) and paclitaxel with carboplatin (Pac/Car) are common regimens used in concurrent chemoradiotherapy (CCRT) for patients with locally advanced esophageal cancer (EC). Here, we aimed to compare the survival outcomes and treatment-related toxicities between these regimens in neoadjuvant CCRT in patients with locally advanced EC. Patients and Methods: One hundred and thirty-six patients with locally advanced EC (98% squamous cell carcinoma) were prospectively recruited between 2016 and 2017 in a non-randomized manner. Patients were categorized into two groups according to the chemotherapeutic agents administered (Pac/Car group, n=87; Cis/5Fu group, n=47) in CCRT to compare the survival outcome and severe adverse event (sAE) incidence. Results: Forty-two patients (85.7%) and 80 patients (91.4%) in the Cis/5Fu and Pac/Car groups completed pre-planned CCRT (p=0.26), respectively. The Cis/5Fu group presented a higher incidence of non-hematological sAE than the Pac/Car group (69.45% vs. 51.7%, p=0.049). Patients in the Pac/Car group showed a higher rate of surgical resection than those in the Cis/5Fu group (49.4% vs. 22.4%, p

Background We previously developed a robust prognostic model (GS model) to predict the survival outcome of patients with advanced pancreatic cancer (APC) receiving palliative chemotherapy with gemcitabine plus S‐1 (GS). This study aimed to validate the application of the GS model in APC patients receiving chemotherapy other than the GS regimen. Patients and methods We retrospectively analyzed 727 APC patients who received first‐line palliative chemotherapy other than the GS regimen between 2010 and 2016 at four institutions in Taiwan. The patients were categorized into three prognostic groups based on the GS model for comparisons of survival outcome, best tumor response, and in‐group survival differences with monotherapy or combination therapy. Results The median survival times for the good, intermediate, and poor prognostic groups were 13.4, 8.4, and 4.6 months, respectively. The hazard ratios for the comparisons of intermediate and poor to good prognostic groups were 1.51 (95% confidence interval [CI]), 1.22‐1.88, P, This study provided validation of the previously developed gemcitabine + S‐1 model in predicting the survival outcome of advanced pancreatic cancer patients receiving first‐line palliative chemotherapy.

Objective Studies have rarely explored the efficacy of S‐1 in treating advanced pancreatic cancer outside Japan. This study compared the survival outcomes of patients with advanced pancreatic cancer treated with S‐1 with the survival outcomes of those without S‐1 treatment before and after S‐1 reimbursement was introduced in Taiwan in June of 2014. Method We retrospectively analyzed 838 patients with locally advanced or metastatic pancreatic cancer who underwent palliative chemotherapy from 2010 to 2016 at 4 institutes in Taiwan. For survival analysis, patients were categorized into two groups according to whether they received S‐1 treatment as palliative chemotherapy after diagnosis: (a) S‐1‐treated (n = 335) and (b) non‐S‐1‐treated (n = 503) groups. Results The median overall survival was longer in the S‐1‐treated group than in the non‐S‐1‐treated group (10.7 vs 6.0 mo, P

Summary: Background: Determining the survival outcome for gastric cancer patients with metastases to more than 15 regional lymph nodes is difficult. This study aims to develop a lymph node metastatic ratio (LNR)-based prognostic model to predict the survival outcome after D2 surgery in such patient groups. Methods: Our study retrospectively enrolled 139 gastric cancer patients with metastases to more than 15 regional lymph nodes who underwent D2 surgery between 2007 and 2014. Clinicopathologic variables to predict overall survival (OS) using multivariate Cox regression were selected to create a prognostic model. Results: The prognostic model for predicting OS was developed based on five independent factors, namely, T-classification (T2 or T3 vs. T4), LNR (

Background/aim This study was designed to clarify the value of routine alpha-fetoprotein (AFP) testing for patients with gastric cancer (GC). Patients and methods A total of 905 patients with newly diagnosed GC and available pretreatment carcinoembryonic antigen (CEA), cancer-related antigen 19-9 (CA19-9), and AFP data from 2010 to 2016 were collected for comparison of tumor stage and survival. Results In total, 139 patients (15.4%), 155 patients (17.1%), and 27 patients (3.0%) had elevated CEA, CA19-9, and AFP levels, respectively. The c-index values of elevated AFP levels in predicting stage IV disease and the 1-year mortality rate were 0.564 (95%CI=0.520-0.608) and 0.594 (95%CI=0.553-0.635), respectively, which were significantly lower than those of CEA (0.673 and 0.665) and CA19-9 (0.619 and 0.618). Conclusion Elevated AFP is rare in patients with newly diagnosed GC. Routine AFP sampling would not provide a higher survival prediction in GC patients than CEA or CA19-9.

Concurrent chemoradiotherapy (CCRT) treatment incompletion is a known negative prognosticator for patients with head and neck cancer (HNC). Malnutrition is a common phenomenon which leads to treatment interruption in patients with HNC. We aimed to compare the performance of three nutritional tools in predicting treatment incompletion in patients with HNC undergoing definitive CCRT. Three nutritional assessment tools, Mini Nutritional Assessment-Short Form (MNA-SF), Malnutritional Universal Screening Tool (MUST), and Nutritional Risk Screening 2002 (NRS-2002), were prospectively assessed prior to CCRT for HNC patients. Patients were stratified into either normal nutrition or malnourished groups using different nutrition tools. Treatment incompletion and treatment-related toxicities associated with CCRT were recorded. A total of 461 patients were included in the study; malnourished rates ranged from 31.0 to 51.0%. The CCRT incompletion rates were 4.9–6.3% and 14.5–18.2% for normal nutrition patients and malnourished patients, respectively. The tools had significant correlations with each other (Pearson correlation 0.801–0.837, p

Nutritional counseling is frequently overlooked in cancer patients with normal nutritional status. This study aimed to evaluate the impact of nutritional counseling in head and neck cancer (HNC) patients with normal nutritional status prior to concurrent chemoradiotherapy (CCRT).A total of 243 patients with pretreatment normal nutritional status and locally advanced HNC receiving concurrent chemoradiotherapy (CCRT) at three medical centers were enrolled. All patients were retrospectively allocated into the early (≤ 2 weeks, n = 105, 43.2%), late (2 weeks, n = 102, 42.0%), and no nutritional counseling groups (n = 36, 14.8%) according to the time interval between the date of CCRT initiation and the first date of nutritional counseling for comparison.The 1-year overall survival rates were 95.0%, 87.5%, and 81.3% in the early, late, and no nutritional counseling groups (p = 0.035), respectively. The median body weight changes at end of CCRT were - 4.8% (range, - 13.3 to 8.7%), - 5.6% (range, - 21.9 to 5.6%), and - 8.6% (range, - 20.3 to 2.4%) in patients in the early, late, and no nutritional counseling groups, respectively. The early termination of chemotherapy rates and the incompletion rates of planned radiotherapy were 1.9% and 1.9%, 2.9%, and 2.0%, 13.9%, and 19.4% in patients in the early, late, and no nutritional counseling groups, respectively.Our findings strongly suggest that while some HNC patients may have pretreatment normal nutritional status, early nutritional counseling is nevertheless essential for the improvement of treatment tolerance and survival outcome.

No gold standard of nutritional assessment is established among patients with head and neck cancer (HNC) receiving concurrent chemoradiotherapy (CCRT). This study aimed to evaluate the clinical significance of pre-treatment nutritional status using the Mini Nutritional Assessment-short form (MNA-SF) among HNC patients receiving CCRT. A total of 461 consecutive patients with newly diagnosed HNC treated with definitive CCRT at three medical institutes were prospectively enrolled. Nutritional status was assessed using MNA-SF within 7 days before CCRT initiation. Patients were classified as having normal nutrition, at risk of malnutrition, and malnourished groups according to MNA-SF for comparison. The 1-year overall survival rates were 89.8%, 76.8%, and 67.7% in the normal nutrition, at risk of malnutrition, and malnourished groups, respectively. Patients with normal nutrition had significantly lower rates of uncompleted radiotherapy and chemotherapy (4.5% and 4.1%, respectively) compared with patients at risk for malnutrition (14.1% and 11.5%, respectively) and those malnourished (11.1% and 11.1%, respectively). Patients with normal nutrition had significantly lower treatment-related complication rates regarding emergency room visits, hospital admission, and need for tubal feeding than those with at risk of malnutrition and malnourished. Patients with normal nutrition had significantly fewer severe hematologic toxicities (p = 0.044) and severe non-hematologic toxicities (p = 0.012) of CCRT than those malnourished. Pre-CCRT nutritional status identifies HNC patients vulnerable to treatment interruption and treatment complications. We suggest that nutritional assessment with MNA-SF should be incorporated in pre-CCRT evaluation for all HNC patients.

Summary: Background: Given the global increase in aging populations and cancer incidence, understanding the influence of age on postoperative outcome after cancer surgery is imperative. This study aimed to evaluate the impact of age on survival outcome in solid cancer patients receiving curative surgery. Methods: A total of 37,288 patients receiving curative surgeries for solid cancers between 2007 and 2012 at four affiliated Chang Gung Memorial Hospital were included in the study. All patients were categorized into age groups by decades for survival analysis. Results: The percentages of patient populations aged

Purpose: Being elevated body mass index (BMI) has been considered a poor prognostic factor in patients with cancer. However, studies about the impact of elevated BMI on the survival outcome after cancer surgery have conflicting results. This study aimed to evaluate the impact of BMI on long-term postoperative survival outcome in a large cohort of Asian population with solid cancers. Methods: A total of 33,551 patients who underwent curative-intent surgery for solid cancers between January 2007 and December 2012 at four hospitals in Taiwan were included. BMI was analyzed using univariate and multivariate regression analyses to determine its association with survival outcome. Results: With a median follow-up of 43.8 (range, 1-91) months, the rate of all-cause mortality was 21.7% (n=7264 patients), while that of cancer-related mortality was 13.4% (n=4499 patients). BMI was a significant prognostic factor in multivariate analysis for overall survival (OS) and cancer-specific survival (CSS). The adjusted hazard ratio (HR) per kg/m2 was 0.922 (95% confidence interval [CI], 0.916-0.929; P 35 kg/m2. Conclusions: This study showed that BMI was positively associated with survival outcome in patients with cancer who underwent radical surgery. BMI was an independent prognostic factor and can be used to risk stratify patients in Asians with solid cancers.

Background: Stage III gastric cancer is characterized by locally advanced disease with varying anatomic extent as measured by the 7th edition of the American Joint Committee on Cancer (AJCC) staging system. There are no prognostic factors specifically identified in patients with stage III gastric cancer following extended lymph node dissection (D2) surgery. Materials and Methods: From 2007 to 2014, 534 patients with stage III gastric cancer underwent radical gastrectomy and D2 dissection at the Chang Gung Memorial Hospital. Patients' characteristics and the impact of adjuvant chemotherapy were analyzed using univariate and multivariate analyses to identify variables associated with overall survival (OS) and disease-free survival (DFS). Results: There were 320 deaths (60.0%) and 284 recurrences (53.2%) by the end of the study. The median OS and DFS were 30.7 months (95% confidence interval [CI]: 27.5-33.9) and 26.4 months (95% CI: 21.2-31.6), respectively. The multivariate analysis identified 7 variables that were independent prognostic factors both for OS and DFS including ratio of metastatic lymph nodes to total resection lymph nodes, carcinoembryonic antigen level, Eastern Cooperative Oncology Group performance status, gastrectomy method, vascular invasion, surgical margin, and adjuvant chemotherapy. Patients with stage IIIA-IIIC disease who received adjuvant chemotherapy had better OS and DFS outcomes than those who did not. Conclusions: Our study identified several independent prognostic factors that might help determine the appropriate counseling patients following surgical treatment. D2 surgery alone was inadequate to achieve long-term survival. As the only correctable independent prognostic factor, postoperative adjuvant chemotherapy should be recommended for eligible patients with stage III gastric cancer.
