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.

Effectiveness of fentanyl buccal soluble film in cancer patients with inadequate breakthrough pain control.

BACKGROUND: Clinical evidence for the rapidity and effectiveness of fentanyl buccal soluble film (FBSF) in reducing pain intensity of breakthrough cancer pain (BTcP) remains inadequate. This study aimed to evaluate the efficacy of FBSF proportional to the around-the-clock (ATC) opioid regimens in rapidly relieving the intensity of BTcP episodes by determining the percentage of patients requiring further dose titration. METHODS: The study procedure included a dose-finding period followed by a 14-day observation period. Pain intensity was recorded with a Numeric Rating Scale (NRS) at onset and 5, 10, 15, and 30 min after FBSF self-administration. Meaningful pain relief was defined as the final NRS score ≤ 3. Satisfaction survey was conducted for each patient after treatment using the Global Satisfaction Scale. RESULTS: A total of 63 BTcP episodes occurred in 30 cancer patients. Only one patient required rescue medication at first BTcP episode and then achieved meaningful pain relief after titrating FBSF by 200 µg. Most BTcP episodes relieved within 10 min. Of 63 BTcP episodes, 30 (47.6%), 46 (73.0%), and 53 (84.1%) relieved within 5, 10, and 15 min after FBSF administration. Only grade 1/2 adverse events were reported, including somnolence, malaise, and dizziness. Of the 63 BTcP episodes, 82.6% were rated as excellent/good satisfaction with FBSF. CONCLUSION: FBSF can be administrated "on demand" by cancer patients at the onset of BTcP, providing rapid analgesia by achieving meaningful pain relief within 10 min. TRIAL REGISTRATION: This study was retrospectively registered 24 December, 2021 at Clinicaltrial.gov (NCT05209906): https://clinicaltrials.gov/study/NCT05209906 .

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.

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 (

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.

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.

A prospective nutritional assessment using Mini Nutritional Assessment-short form among patients with head and neck cancer receiving concurrent chemoradiotherapy.

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

External validation of the Besançon nomogram in Asian patients with advanced pancreatic cancer receiving second-line chemotherapy: A multi-institute experience in Taiwan.

BACKGROUND: Determining survival outcome in advanced pancreatic ductal adenocarcinoma (aPDAC) patients receiving second-line (L2) chemotherapy is important for clinical decision-making. The Besançon group from France recently proposed a prognostic nomogram to predict overall survival (OS) for aPDAC patients receiving L2 chemotherapy. The present study aimed to externally validate the performance of the Besançon nomogram in predicting OS in an Asian cohort. METHODS: We retrospectively enrolled 349 patients who received L2 chemotherapy for aPDAC between 2010 and 2016 at four institutes in Taiwan. The performance of the Besançon model in this cohort was evaluated with C-index and calibration plots. RESULTS: The median OS time in our patient cohort was 4.5 months (95% confidence interval [CI], 3.0-5.0). Using the Besançon nomogram-predicted risk groups, the median OS times in the low, intermediate, and high-risk groups were 6.7 (95% CI, 5.3-8.2), 3.2 (95% CI, 2.4-3.9), and 1.7 months (95% CI, 0.6-2.7), respectively. The C-index of the predicted six- and 12-month survival probabilities for the Besançon nomogram were 0.766 (95% CI, 0.715-0.816) and 0.698 (95% CI, 0.641-0.754), respectively. The calibration plot showed that the observed six-month survival probability was close to the diagonal line, while that for 12-month survival deviated below the diagonal line compared to the survival probability predicted by the Besançon nomogram. CONCLUSIONS: Although the Besançon nomogram tended to over-estimate the 12-month survival probability, our study demonstrated that the nomogram is a reliable and readily applicable model to estimate survival outcomes of aPDAC patients receiving L2 chemotherapy.

Application of comprehensive geriatric assessment in predicting early mortality among elder patients with B-cell lymphoma receiving immunochemotherapy.

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.

Development and validation of a prognostic nomogram to predict survival in patients with advanced pancreatic cancer receiving second-line palliative chemotherapy.

BACKGROUND AND AIM: Given that a wide variation in tumor response rates and survival times suggests heterogeneity among the patients with advanced pancreatic cancer (APC) who underwent second-line (L2) chemotherapy, it is a challenge in clinical practice to identify patients who will receive the most benefit from L2 treatment. METHODS: We selected 183 APC patients who received L2 palliative chemotherapy between 2010 and 2016 from a medical center as the development cohort. A Cox proportional hazard model was used to identify the prognostic factors and construct the nomogram. An independent cohort of 166 patients from three other hospitals was selected for external validation. RESULTS: The nomogram was based on eight independent prognostic factors from the multivariate Cox model: sex, Eastern Cooperative Oncology Group performance status, reason for first-line treatment discontinuation, duration of first-line treatment, neutrophil-to-lymphocyte ratio, tumor stage, body mass index, and serum carbohydrate antigen 19-9 levels at the beginning of L2 treatment. The model exhibited good discrimination ability, with a C-index of 0.733 (95% confidence interval, 0.681-0.785) and 0.724 (95% confidence interval, 0.661-0.787) in the development and validation cohorts, respectively. The calibration plots of the development and validation cohorts showed optimal agreement between model prediction and actual observation in predicting survival probability at 6 months, 1 year, and 2 years. CONCLUSIONS: This study developed and externally validated a prognostic model that accurately predicts the survival outcome of APC patients before L2 palliative chemotherapy, which could assist in clinical decision-making, counseling for treatment, and most importantly, prognostic stratification of patients.

A nationwide survey of adherence to analgesic drugs among cancer patients in Taiwan: prevalence, determinants, and impact on quality of life.

PURPOSE: Poor adherence to analgesic drugs is one of the most common barriers to adequate pain management. This prospective, cross-sectional, patient-oriented observational study aimed to explore the adherence rate, clinical factors, and impact of adherence to analgesic drugs on the quality of life (QoL) among cancer outpatients in Taiwan. METHODS: Eight hundred ninety-seven consecutive adult outpatients with cancer who had reported tumor pain and received regular analgesic drug treatment were enrolled from 16 medical centers across Taiwan. The Brief Pain Inventory was used to assess pain intensity and QoL. Morisky's four-item medication adherence scale was used to assess adherence to analgesic drugs. Clinical factors possibly associated with good adherence to analgesic drugs were analyzed using multivariate logistic regression analyses. RESULTS: Of the 897 patients, 26.9% met criteria for the good, 35.5% for the moderate, and 37.6% for the poor adherence groups. The good adherence group had significantly better QoL outcomes than the moderate and poor adherence groups (all p < 0.05). Age ≥ 50 years, head and neck or hematological malignancies, cancer-related pain, patients who agreed or strongly agreed that the side effects of analgesic drugs were tolerable, and patients who disagreed or strongly disagreed that the dosing schedule could be flexibly self-adjusted to deal with the actual pain were predictors of good adherence to analgesic drugs. CONCLUSIONS: Awareness of the clinical factors associated with adherence to analgesic drugs may help clinicians to identify cancer patients at a greater risk of non-adherence, reinforce optimal pain management, and improve the QoL by enhancing adherence to pain medications.

Clinical characteristics and survival outcomes of terminally ill patients undergoing withdrawal of mechanical ventilation.

BACKGROUND: Withdrawal of mechanical ventilation is an important, but rarely explored issue in Asia during end-of-life care. This study aimed to describe the clinical characteristics and survival outcomes of terminally ill patients undergoing withdrawal of mechanical ventilation in Taiwan. METHODS: One-hundred-thirty-five terminally ill patients who had mechanical ventilation withdrawn between 2013 and 2016, from a medical center in Taiwan, were enrolled. Patients' clinical characteristics and survival outcomes after withdrawal of mechanical ventilation were analyzed. RESULTS: The three most common diagnoses were organic brain lesion, advanced cancer, and newborn sequelae. The initiator of the withdrawal process was family, medical personnel, and patient him/herself. The median survival time was 45 min (95% confidence interval, 33-57 min) after the withdrawal of mechanical ventilation, and 102 patients (75.6%) died within one day after extubation. The median time from diagnosis of disease to receiving life-sustaining treatment and artificial ventilation support, receiving life-sustaining treatment and artificial ventilation support to "Withdrawal meeting," "Withdrawal meeting" to ventilator withdrawn, and ventilator withdrawn to death was 12.1 months, 19 days, 1 day, and 0 days, respectively. Patients with a diagnosis of advanced cancer and withdrawal initiation by the patients themselves had a significantly shorter time interval between receiving life-sustaining treatment and artificial ventilation support to "Withdrawal meeting" compared to those with non-cancer diseases and withdrawal initiation by family or medical personnel. CONCLUSION: This study is the first observational study to describe the patients' characteristics and elaborate on the survival outcome of withdrawal of mechanical ventilation in patients who are terminally ill in an Asian population. Understanding the clinical characteristics and survival outcomes of mechanical ventilation withdrawal might help medical personnel provide appropriate end-of-life care and help patients/families decide about the withdrawal process earlier.

Survival outcomes of geriatric patients with clinically resectable gastric cancer: to operate or not.

BACKGROUND: Approximately, 50% of all gastric cancer patients are aged >70 y. Although curative surgery is the treatment of choice, many geriatric patients die of surgical complications. Therefore, we aimed to evaluate the impact of radical surgery on the survival outcome of geriatric patients with resectable gastric cancers. METHODS: About 488 patients diagnosed with resectable gastric cancers, aged ≥70 y, between January 2007 and December 2012 at Chang Gung Memorial Hospital (CGMH) Linkou branch were included in this study. Using univariate and multivariate analyses, possible prognostic variables for survival outcome were assessed in 445 patients (91.2%) treated with radical surgery (operation [OP] group) and 43 (8.8%) receiving conservative treatment (non-OP group). The impact of radical surgery on survival outcomes was evaluated according to CGMH scores. RESULTS: On multivariate analysis, surgical resection with subtotal gastrectomy and CGMH score were the only independent prognostic factors for both overall and cancer-specific survival. The median survival time was 43 mo for the entire cohort. The OP group had significantly better survival outcome than the non-OP group (median survival, 50.3 versus 16.2 mo, P < 0.001). The median survival times for patients with CGMH scores ≤20 were 64.1 and 20.0 mo (P < 0.002) and those for patients with CGMH scores >20 were 13.8 and 10.4 mo (P = 0.18) in the OP and non-OP groups, respectively. CONCLUSIONS: Surgical resection and CGMH score are independent prognostic factors for overall and cancer-specific survival; the CGMH score might be a prognostic indicator of surgical outcome in geriatric patients with resectable gastric cancers.

Magnitude of score change for the palliative prognostic index for survival prediction in patients with poor prognostic terminal cancer.

PURPOSE: The use of the palliative prognostic index (PPI) when used only at an initial assessment might be inappropriate as a prognostic tool because it does not reflect the patient's clinical course. The purpose of this study was to assess the utility of PPI score change (∆score) between two assessments as a prognostic tool in terminally ill cancer patients categorized as having a poor prognosis. METHODS: A total of 1,035 terminally ill cancer patients categorized as having a poor prognosis (initial PPI score >6) under palliative care between January 2006 and December 2011 at a single medical center in Taiwan were selected. Patients were categorized by magnitude of ∆score between the initial PPI and week 1 PPI assessments into five groups (<-20, -20 to 0, 0, 0 to 20, and >20 %) for survival analysis. RESULTS: The median survival was 22 days (range, 8-180 days) in all patients. Median survival duration was 78, 32, 23, 17, and 14 days, and the death rate at the study end was 78.9, 87.1, 96.2, 100, and 100 % in each group, respectively. The c-statistic value for predicting life expectancy less than 30, 60, and 90 days was significantly higher with magnitude of ∆score than with the initial PPI score (p < 0.05). CONCLUSIONS: Magnitude of PPI score change within 1-week interval provides a significant difference in survival prediction and is more reliable than initial PPI alone to identify terminally ill cancer patients with better outcome potential in those patients considered to have a poor prognosis.

Evaluating the cancer aging and research group model in predicting immunochemotherapy toxicity among elderly patients with diffuse large B-cell lymphoma.

BACKGROUND: The management of diffuse large B-cell lymphoma (DLBCL) in elderly patients is complicated by an increased risk of treatment-related toxicity associated with aging. This study aimed to validate the effectiveness of the Cancer Aging and Research Group (CARG) model in elderly patients with DLBCL receiving rituximab-based chemotherapy. METHODS: In this prospective study, elderly DLBCL patients (aged 65 years or older) receiving rituximab-based chemotherapy were consecutively assessed between August 2016 and December 2021 at one medical center in Taiwan using the CARG model to predict treatment-related toxicity. Patients were categorized into low-, medium-, and high-risk groups based on their CARG scores. Comparisons were made regarding toxicities and survival rates among these groups. RESULTS: Ninety-one patients, with a median age of 70 years (range 65-96), were included. A substantial 81 % (74 patients) experienced grade 3-5 toxicity. The overall 2-year survival rate was 63.8 % after a median follow-up of 28 months (range, 2-46). The risk of grade 3-5 toxicity was 83 %, 78 %, and 87 %, respectively, among the low-, medium-, and high-risk groups (p = 0.60). The receiver operating characteristic (ROC) curve for CARG was 0.521 (95 % CI, 0.376-0.666), which was significantly lower than that for the Eastern Cancer Oncology Group score (ROC = 0.701, 95 % CI, 0.571-0.831). Similarly, compared with those of low-risk patients, hazard ratios for overall survival were 9.22 (95 % CI, 1.23-69.1; p = 0.031) and 14.6 (95 % CI, 1.90-112; p = 0.010) for medium- and high-risk patients, respectively. CONCLUSION: While CARG exhibited limitations in predicting treatment-related toxicity in elderly DLBCL patients, it demonstrated potential efficacy in predicting survival outcomes.

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.

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.
