Impact of pretreatment quality of life on tolerance and survival outcome in head and neck cancer patients undergoing definitive CCRT.

BACKGROUND: Health-related quality of life (HRQoL) is a predictor of treatment outcomes in cancer patients. This study aimed to evaluate the effect of pretreatment HRQoL on treatment tolerance and survival outcomes in patients with HNC planned for concurrent chemoradiotherapy (CCRT) in Taiwan. METHODS: This study included 461 patients with HNC planned for definitive CCRT at three medical centers in Taiwan between August 2017 and December 2018. HRQoL was assessed using the QLQ-HN35 one week before the initiation of CCRT. Patients were grouped based on the sum scores of QLQ-HN35 (

Frailty is an independent factor for health-related quality of life in patients with head and neck cancer receiving definitive concurrent chemoradiotherapy.

PURPOSE: Health-related quality of life (HRQoL) is associated with treatment-related complications and poor survival in patients with head and neck cancer (HNC). We investigated the effects of frailty on HRQoL in patients with HNC receiving definitive concurrent chemoradiotherapy (CCRT). METHODS: A total of 461 consecutive patients with locally advanced HNC who received CCRT between 2017 and 2018 at three medical centers in Taiwan were included. Frailty and HRQoL were assessed using the Comprehensive Geriatric Assessment and QLQ-H&N35 before CCRT. The sum score was calculated based on the first 30 questions of QLQ-H&N35. Multivariate analysis was performed to evaluate the impact of frailty on HRQoL. RESULTS: The overall sum score was 39 (34-49). The sum scores of patients with impairments in 0, 1, 2, 3, and ≥ 4 frailty domains were 34 (32-38), 40 (34-47), 46 (36-55), 48 (41-64), and 56 (50-60), respectively. Patients with impairments in more frailty domains had a higher symptom burden (p for trend < 0.001). Frail patients tended to experience symptoms across all QLQ-H&N35 subscales. Sex, body mass index, tumor type, tumor stage, Eastern Cooperative Oncology Group performance status, and frailty were determinants of HRQoL in the univariate analysis. Frailty was an independent determinant of HRQoL in the multivariate analysis. CONCLUSION: Routine frailty assessment may serve as a surrogate for the selection of patients with HNC with poor HRQoL before CCRT. Further studies are needed to determine whether appropriate interventions in frail patients would improve their HRQoL during CCRT.

Impact of preoperative frailty on the surgical and survival outcomes in older patients with solid cancer after elective abdominal surgery.

BACKGROUND: Frailty is common in older patients with cancer; however, its clinical impact on the survival outcomes has seldom been examined in these patients. This study aimed to investigate the association of frailty with the survival outcomes and surgical complications in older patients with cancer after elective abdominal surgery in Taiwan. METHODS: We prospectively enrolled 345 consecutive patients aged ≥65 years with newly diagnosed cancer who underwent elective abdominal surgery between 2016 and 2018. They were allocated into the fit, pre-frail, and frail groups according to comprehensive geriatric assessment (CGA) findings. RESULTS: The fit, pre-frail, and frail groups comprised 62 (18.0%), 181 (52.5%), and 102 (29.5%) patients, respectively. After a median follow-up of 48 (interquartile range, 40-53) months, the mortality rates were 12.9%, 31.5%, and 43.1%, respectively. The adjusted hazard ratio was 1.57 (95% confidence interval [CI], 0.73-3.39; p = 0.25) and 2.87 (95% CI, 1.10-5.35; p = 0.028) when the pre-frail and frail groups were compared with the fit group, respectively. The frail group had a significantly increased risk for a prolonged hospital stay (adjusted odds ratio, 2.22; 95% CI, 1.05-4.69; p = 0.022) compared with the fit group. CONCLUSION: Pretreatment frailty was significantly associated with worse survival outcomes and more surgical complications, with prolonged hospital stay, in the older patients with cancer after elective abdominal surgery. Preoperative frailty assessment can assist physicians in identifying patients at a high risk for surgical complications and predicting the survival outcomes of older patients with cancer.

Frailty assessment by two screening instruments in non-elderly patients with head and neck cancer.

PURPOSE: Frailty assessment is often overlooked in non-elderly patients with cancer, possibly due to the lack of an effective frailty screening tool. This study aimed to evaluate the performance of two modern frailty screening tools, the Flemish version of the Triage Risk Screening Tool (fTRST) and the modified 5-Item Frailty Index (mFI-5), compared to the gold standard comprehensive geriatric assessment (GA) among non-elderly patients with head and neck cancer (HNC). METHODS: We prospectively included 354 consecutive patients aged < 65 years with newly diagnosed HNC scheduled for definitive concurrent chemoradiotherapy (CCRT) at three academic hospitals in Taiwan between January 2020 and December 2022. Frailty assessment using the GA, fTRST, and mFI-5 was performed in all patients to evaluate the relationship between frailty and treatment outcomes. RESULTS: The prevalence of frailty was 27.1%, 37.0%, and 42.4% based on GA, mFI-5, and fTRST, respectively. mFI-5 and fTRST demonstrated good predictive value in identifying frail patients compared to the GA. Patients with frailty, as defined by GA, mFI-5, and fTRST, exhibited higher risks of treatment-related complications, incomplete treatment, and poorer baseline quality of life (QoL). However, only GA showed significant prognostic value for overall survival. CONCLUSIONS: Frailty assessment using fTRST and mFI-5 is valuable for predicting treatment-related adverse events, treatment tolerance, and QoL in non-elderly patients with HNC. Incorporating frailty assessment into the management of non-elderly cancer patients can aid in the identification of high-risk individuals. However, the performance of these tools varies, highlighting the need for further validation and refinement.

A multicenter retrospective analysis of patients with salivary gland carcinoma treated with postoperative radiotherapy alone or chemoradiotherapy.

BACKGROUND: The aim of this study was to interrogate if the use of postoperative chemoradiotherapy (POCRT) correlated with superior oncological outcomes for certain subgroups of patients with high-risk salivary gland carcinoma (SGC), compared with postoperative radiotherapy (PORT) alone. METHODS: This multicenter retrospective study included 411 patients with surgically resected SGC who underwent PORT (n = 263) or POCRT (n = 148) between 2000 and 2015. Possible correlations of clinical parameters with outcomes were examined using the Kaplan-Meier analysis and Cox proportional-hazards regression model. RESULTS: The median follow-up of survivors is 10.9 years. For the entire cohort, adding concurrent chemotherapy to PORT was not associated with OS, PFS, or LRC improvement. However, patients with nodal metastasis who underwent POCRT had significantly higher 10-year OS (46.2% vs. 18.2%, P = 0.009) and PFS (38.7% vs. 10.0%, P = 0.009) rates than those treated with PORT alone. The presence of postoperative macroscopic residual tumor (R2 resection) was identified as an independent prognosticator for inferior OS (P = 0.032), PFS (P = 0.001), and LRC (P = 0.007). Importantly, POCRT significantly correlated with higher 10-year LRC rates in patients with R2 resection (74.2% vs. 40.7%, P = 0.034) or adenoid cystic carcinoma (AdCC, 97.6% vs. 83.6%, P = 0.039). On multivariate analyses, the use of POCRT significantly predicted superior OS (P = 0.037) and PFS (P = 0.013) for node-positive patients and LRC for patients with R2 resection (P = 0.041) or AdCC (P = 0.005). CONCLUSIONS: For surgically resected SGC, POCRT was associated with improved long-term OS and PFS for patients with nodal metastasis and superior LRC for patients with R2 resection or AdCC.

Pretreatment frailty is an independent prognostic factor among elderly patients with B-cell lymphoma undergoing immunochemotherapy: A prospective observational cohort study in Taiwan.

BACKGROUND/PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Association of preoperative frailty and postoperative delirium in older cancer patients undergoing elective abdominal surgery: A prospective observational study in Taiwan.

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Risk factors and effect of postoperative delirium on adverse surgical outcomes in older adults after elective abdominal cancer surgery in Taiwan.

BACKGROUND: Postoperative delirium (POD) is a common complication in older adults, with unknown epidemiology and effects on surgical outcomes in Asian geriatric cancer patients. This study evaluated incidence, risk factors, and association between adverse surgical outcomes and POD after intra-abdominal cancer surgery in Taiwan. METHODS: Overall, 345 patients aged ≥65 years who underwent elective abdominal cancer surgery at a medical center in Taiwan were prospectively enrolled. Delirium was assessed daily using the Confusion Assessment Method. Univariate and multivariate logistic regression analyses investigated risk factors for POD occurrence and estimated the association with adverse surgical outcomes. RESULTS: POD occurred in 19 (5.5%) of the 345 patients. Age ≥73 years, Charlson comorbidity index ≥3, and operative time >428 min were independent predictors for POD occurrence. Patients presenting with one, two, and three risk factors had 4.1-fold (95% confidence interval [CI], 0.4-35.8, p = 0.20), 17.4-fold (95% CI, 2.2-138, p = 0.007), and 30.8-fold likelihood (95% CI, 2.9-321, p = 0.004) for POD occurrence, respectively. Patients with POD had a higher probability of prolonged hospital stay (adjusted odds ratio [OR] 2.8; 95% CI, 1.0-8.1; p = 0.037), intensive care stay (adjusted OR: 3.9; 95% CI, 1.5-10.5; p = 0.008), 30-day readmission (adjusted OR 3.1; 95% CI, 1.1-9.7; p = 0.039), and 90-day postoperative death (adjusted OR: 4.2; 95% CI, 1.0-17.7; p = 0.041). CONCLUSION: POD occurrence was significantly associated with adverse surgical outcomes in geriatric patients undergoing elective abdominal cancer surgery, highlighting the importance of early POD identification in geriatric patients to improve postoperative care quality.

External validation of a risk model for survival prediction in older patients with cancer undergoing elective abdominal surgery: a prospective cohort study.

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; P<0.001) and 10.1 (95% CI, 5.84-17.6; P<0.001) 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.

Potential Utility of the Mallampati Score for Prediction of Treatment Compliance and Safety Profiles of Patients With Head and Neck Cancer Undergoing Definitive Concurrent Chemoradiotherapy.

BACKGROUND/AIM: Restriction of mouth opening (RMO) is a common manifestation of head and neck cancer (HNC) and a poor prognostic factor following concurrent chemoradiotherapy (CCRT) of patients. This study aimed to explore whether the Mallampati score, a visual assessment of the distance from the tongue base to the roof of the mouth, can be used as a surrogate for RMO in predicting treatment outcomes in patients with HNC undergoing CCRT. PATIENTS AND METHODS: A total of 461 consecutive patients who received definitive CCRT for the treatment of locally advanced HNC between August 2016 and December 2017 at Chang Gung Memorial Hospital in Taiwan (Linkou, Keelung, and Kaohsiung branches) were enrolled in this prospective study. Patients were allocated by the pre-treatment Mallampati score of 1 or 2 (n=24) vs. 3 or 4 (n=207) to compare treatment compliance and treatment-related complications. RESULTS: Patients in the Mallampati score of 3 or 4 group had a higher prevalence of betel quid chewing, oral cavity and oropharynx cancers, advanced tumor stage, poorer performance status, and were more likely to receive platinum monotherapy during CCRT. Patients in the Mallampati score of 3 or 4 group had a 2.08-fold (p=0.002) hazard ratio (HR) for overall survival compared to those in the score of 1 or 2 group in the univariate analysis, the difference remained significant in multivariate analysis (adjusted HR=1.61; 95% CI=1.02-2.61; p=0.047). Patients in the Mallampati score 3 or 4 group had a 2.36-fold (95% CI=1.07-5.19; p=0.033) increased likelihood of incomplete chemotherapy, 2.44-fold (95% CI=1.17-5.06; p=0.017) increased likelihood of incomplete radiotherapy, and 1.84-fold (95% CI=1.18-2.87; p=0.007) risk of unexpected hospitalization compared to those with a Mallampati score of 1 or 2 in multivariate analysis. CONCLUSION: Patients with HNC with higher pre-treatment Mallampati scores had poorer survival outcomes and were at a higher risk of treatment incompletion and treatment-related toxicities when undergoing CCRT. Our results support the utility of Mallampati score as a surrogate for measuring RMO to predict survival outcomes, treatment compliance, and safety profiles in patients with HNC undergoing CCRT.

Predictive Value of Albumin and Neutrophil-to-Lymphocyte Ratio Score for Treatment Completeness and Safety Profiles in Patients With Head and Neck Cancer Receiving Definitive Concurrent Chemoradiotherapy.

BACKGROUND/AIM: Malnutrition and inflammation are common conditions in patients with head and neck cancer (HNC). This study aimed to evaluate the predictive value of albumin combined with neutrophil-lymphocyte ratio (NLR), referring to the albumin-NLR score (ANS), in the prediction of treatment completeness and safety profiles in HNC patients receiving definitive concurrent chemoradiotherapy (CCRT). PATIENTS AND METHODS: 461 consecutive HNC patients who received CCRT between 2016 and 2017 at three medical centers in Taiwan were prospectively enrolled and divided into three different groups based on their pretreatment ANS (ANS 0, high albumin and low NLR; ANS 1, low albumin or high NLR; and ANS 2, low albumin and high NLR) for treatment completeness and safety profiles comparison. RESULTS: Overall, 46 patients (10.0%) had incomplete CCRT treatment. Patients in the ANS 2 group experienced a higher rate of incomplete CCRT (20.9%) than those in the ANS 1 (7.4%) and ANS 0 (3.5%) groups. ANS had a better discriminatory ability in predicting CCRT completeness in terms of -2 log-likelihood value, chi-square value, and c-index than the prognostic nutritional index. Patients in the ANS 2 group had significantly higher incidences of grade 3 or higher leukopenia, anemia, neutropenia, thrombocytopenia, non-neutropenic infection, and hypokalemia than those in the other two ANS groups. CONCLUSION: Our study showed that the ANS can accurately predict the treatment completeness of CCRT in patients with HNC and can be widely used as a simple predictor of treatment tolerance and safety profiles in patients with HNC undergoing CCRT.

Albumin and Neutrophil-to-Lymphocyte Ratio Score in Neoadjuvant Concurrent Chemoradiotherapy for Esophageal Cancer: Comparison With Prognostic Nutritional Index.

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<0.001, respectively). ANS had better performance in overall survival evaluation and discrimination ability than PNI and individual albumin and NLR. Patients in the ANS 0, 1, and 2 had radiotherapy incompletion rates of 2.6%, 3.9%, and 18.2%, respectively, and chemotherapy incompletion rates of 5.1%, 7.8%, and 30.3%, respectively. Patients in the ANS 2 group were significantly associated with a higher incidence of infection (30.3%) than those in the ANS 0 (10.3%) and ANS 1 groups (9.8%). CONCLUSION: Pre-treatment ANS was significantly associated with CCRT safety profiles, CCRT completion rate, and survival outcome in patients with esophageal cancer with excellent performance compared to PNI and NLR.

Clinical Significance of Frailty on Treatment Outcome in Nongeriatric Patients With Head and Neck Cancer and Esophageal Cancer Undergoing Curative-Intent Concurrent Chemoradiotherapy.

BACKGROUND: Whether the prevalence of frailty and its clinical significance are relevant to treatment outcomes in younger (aged < 65 years) cancer patients remains uncertain. This study aimed to evaluate the impact of frailty on treatment outcomes in younger cancer patients with head and neck and esophageal malignancy. MATERIAL AND METHODS: This multicenter prospective study recruited 502 patients with locally advanced head and neck and esophageal cancer during 2016-2017 in Taiwan, aged 20-64 years who received curative-intent concurrent chemoradiotherapy (CCRT) as first-line antitumor treatment. Baseline frailty assessment using geriatric assessment (GA) was performed for each patient within 7 days before CCRT initiation. RESULTS: Frailty was observed in 169 (33.7%) of 502 middle-aged patients. Frail patients had significantly higher incidences of chemotherapy incompletion (16.6% versus 3.3%, P < .001) and radiotherapy incompletion (16.6% versus 3.6%, P < .001) than fit patients. During CCRT, frail patients had a significantly higher percentage of hospitalizations (42.0% versus 24.6%, P < .001) and a trend toward a higher percentage of emergency room visits (37.9% versus 30.0%, P = .08) than fit patients. Frail patients more likely had a significantly higher incidence of grade ≥ 3 adverse events than fit patients during CCRT. The 1-year survival rate was 68.7% and 85.2% (hazard ratio 2.56, 95% confidence interval 1.80-3.63, P < .001) for frail and fit patients, respectively. CONCLUSIONS: This study demonstrated the significance of pretreatment frailty on treatment tolerance, treatment-related toxicity, and survival outcome in younger patients with head and neck and esophageal cancer undergoing CCRT. While GA is commonly targeted toward the older population, frailty assessment by GA may also be utilized in younger patients for decision-making guidance and prognosis prediction.

Utility of Palliative Prognostic Index in Predicting Survival Outcomes in Patients With Hematological Malignancies in the Acute Ward Setting.

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.

Paclitaxel and Carboplatin Versus Cisplatin and 5-Fluorouracil in Concurrent Chemoradiotherapy in Patients With Esophageal Cancer.

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<0.001). After a median follow-up duration of 22.0 months (range=1.9-31.8), the 2-year survival rate was 56.9% for patients in the Pac/Car group and 28.7% for the Cis/5Fu group. The hazard ratio (HR) of overall survival was 0.45 (95%CI=0.28-0.72, p=0.001) in the comparison between the groups. CONCLUSION: Overall, neoadjuvant CCRT with Pac/Car is associated with a better survival outcome, higher surgical resection rate, and better safety profiles than Cis/5Fu in patients with locally advanced EC.

Impact of Frailty on Treatment Outcome in Patients With Locally Advanced Esophageal Cancer Undergoing Concurrent Chemoradiotherapy.

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<0.001), higher risk of emergent room visiting [relative risk 3.72; 95% confidence interval (CI)=1.39-9.91; p=0.009] and hospitalization (relative risk 3.85; 95% CI=1.03-11.2; p=0.013) during the course of CCRT, when compared to fit patients. Overall survival showed significant worsening in the frail group [adjusted hazard ratio (HR)=2.12; 95% CI=1.01-4.42; p=0.046]. CONCLUSION: Frailty is associated with increase of treatment-related toxicities and poor survival outcome in EC patients undergoing CCRT. Our study suggested that pretreatment frailty assessment is imperative to serve as a predictor and prognostic factor for all adult patients with EC undergoing CCRT.

Alpha-fetoprotein for Gastric Cancer Staging: An Essential or Redundant Tumor Marker?

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.

A comparison of the MNA-SF, MUST, and NRS-2002 nutritional tools in predicting treatment incompletion of concurrent chemoradiotherapy in patients with head and neck cancer.

BACKGROUND: 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. MATERIAL AND METHODS: 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. RESULTS: 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<0.001 for all) and accurately predicted the incompletion of CCRT. MNA-SF had the highest performance in predicting treatment-related toxicity, including emergency room visits, need for hospitalization, any grade III or higher hematological adverse events, and critical body weight loss, compared to the other tools. CONCLUSIONS: MNA-SF, MUST, and NRS2002 were all shown to be competent tools for prediction of treatment incompletion and treatment-related toxicity in HNC patients undergoing CCRT. We suggest implementing nutritional assessment prior to treatment to improve the rate of treatment completion and to reduce treatment-related toxicity in HNC patients.

Impact of early nutrition counseling in head and neck cancer patients with normal nutritional status.

BACKGROUND: 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). METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
