Background Oxaliplatin-based chemotherapy is an alternative systemic treatment for patients with metastatic hepatocellular carcinoma (HCC) who were refractory or intolerant to sorafenib. To date, ...there have been no biomarkers reported to monitor the therapeutic efficacy and to predict the outcomes of HCC patients receiving oxaliplatin-based chemotherapy. Methods Eighty-one HCC patients with elevated baseline α-fetoprotein (AFP) levels and extrahepatic spreading who received oxaliplatin-based chemotherapy between 2012 and 2014 were retrospectively enrolled in this study. Two AFP tests were performed, at baseline and 2–4 weeks after the initiation of chemotherapy. The change in AFP levels was calculated for survival analysis. Results In the AFP decline group (decreased compared to baseline), the median progression-free survival (PFS) and overall survival (OS) were 7.0 months and 12.3 months, respectively. In the AFP nondecline group, the median PFS and OS were 2.3 months and 3.0 months, respectively. The difference in OS between the two groups was significant ( p < 0.005). In the multivariate analysis for disease progression, the best response to chemotherapy and AFP decline were independent factors, with p values of 0.004 and 0.009, respectively. In the multivariate analysis for OS, the baseline Child–Pugh score, best response to chemotherapy, and AFP decline were independent prognostic factors, with p values of 0.01, 0.001, and 0.008, respectively. Additionally, the unit change in AFP level was predictive of PFS and OS with p values of 0.007 and 0.001, respectively. Conclusion The change in AFP levels 2–4 weeks after initiating oxaliplatin-based chemotherapy is useful to predict treatment response and survival.

Aims
The BRAF V600 mutation has been shown to be clinically meaningful in terms of both the prognosis and sensitivity of BRAF inhibitors in patients with metastatic melanoma. Recently, a BRAF V600E ...mutation‐specific antibody, VE1, was generated for the detection of tumors bearing BRAF V600E mutations. To determine the clinical value of immunohistochemical testing, we compared the prevalence of mutant BRAF detected by VE1 with direct sequencing results.
Methods
Paraffin‐embedded, formalin‐fixed melanoma biopsies were analyzed for the BRAF mutation status by immunohistochemistry with the VE1 antibody. Sanger sequencing was applied to verify the immunohistochemical results.
Results
A total of 73 melanoma cases with tumor samples from primary lymph nodes and metastatic sites were selected for this study. Direct sequencing demonstrated that 18 of 73 cases (24.6%) harbored the BRAF V600 mutation: 17 with V600E and one with V600K. All 18 tumors shown to harbor the BRAF V600E/K mutations were VE1‐positive. One additional case was false‐positive for VE1. The sensitivity and specificity of VE1 was 100% (18/18) and 98% (54/55), respectively. The overall concordance between the immunohistochemical method and direct sequencing was excellent (98.6%).
Conclusions
Our findings demonstrate that immunohistochemical analysis using VE1 constitutes a highly sensitive test for the detection of BRAF mutations and suggest that this cost‐effective method is suitable as a rapid diagnostic approach complementary to molecular testing.

The prognosis of patients with resected esophageal squamous cell carcinoma after neoadjuvant chemoradiotherapy is particularly poor in those who were staged as ypT3/T4 and/or ypN+. This study ...investigated whether adjuvant chemoradiotherapy was associated with improved clinical outcomes in these patients.
we identified patients with esophageal squamous cell carcinoma who were staged as ypT3/T4 and/or ypN+ after being treated with neoadjuvant chemoradiotherapy followed by esophagectomy between the years 2013 and 2019. Patients were divided into two groups based on whether they received adjuvant chemoradiotherapy. The Kaplan-Meier method and Cox regression modeling were performed for survival analyses and multivariable analysis, respectively.
76 eligible patients were included in the analyses. The median follow-up for the study cohort was 43.4 months. On Kaplan-Meier analyses of the overall population, adjuvant chemoradiotherapy was associated with significantly improved median overall survival (31.7 months vs. 16.3 months,
= 0.036). On Kaplan-Meier analyses of the 35 matched pairs generated by propensity score matching, adjuvant chemoradiotherapy was associated with significantly longer median overall survival (31.7 months vs. 14.3 months;
= 0.004) and median recurrence-free survival (18.9 months vs. 11.7 months;
= 0.020). In multivariable analysis, adjuvant chemoradiotherapy was independently associated with a 60% reduction in mortality (
= 0.003) and a 48% reduction in risk of recurrence (
= 0.035) after adjusting for putative confounders. In addition, microscopic positive resection margin and Mandard tumor regression grade 3-4 were independently associated with increased mortality and risk of recurrence. While a greater number of lymph nodes dissected was independently associated with significantly improved overall survival, the number of positive lymph nodes was independently associated with significantly worse overall survival and a trend (
= 0.058) towards worse recurrence-free survival.
This study demonstrated that adjuvant CRT was independently associated with a significantly improved survival and lower risk of recurrence than observation in esophageal squamous cell carcinoma patients staged as ypT3 and/or ypN+ after receiving neoadjuvant chemoradiotherapy and radical surgery. The results of this study have implications for the design of future clinical trials and may improve treatment outcomes of patients in this setting who cannot afford or are without access to adjuvant nivolumab.
Abstract
Background/purpose
The purpose of this secondary-analysis study was to identify never-before-examined factors associated with distinct depressive-symptom trajectories among family caregivers ...from end-of-life caregiving through the first 2 bereavement years.
Participants/methods
Participants (
N
=661) were family caregivers who provided end-of-life caregiving for terminally ill cancer patients. Multinomial logistic regressions were conducted to identify modifiable factors associated with caregivers
’
seven previously identified depressive-symptom trajectories: minimal-impact resilience, recovery, preloss-depressive-only, delayed symptomatic, relief, prolonged symptomatic, and chronically persistent distressed. Drawing from the stress-appraisal-coping model, modifiable time-varying factors associated with distinct depressive-symptom trajectories were examined in three domains: (1) stressors, (2) stress appraisal, and (3) available resources (internal coping capacity and external social support)
.
Results
Profound objective caregiving demands were associated with caregivers’ increased likelihood of belonging to more distressing depressive-symptom trajectories than to the minimal-impact-resilience trajectory. But, stronger negative appraisal of end-of-life caregiving increased odds of caregiver membership in preloss-depressive-only and relief trajectories over the recovery, delayed, and prolonged-symptomatic trajectories. Stronger internal coping capacity and perceived social support buffered the tremendous stress of end-of-life caregiving and permanent loss of a relative, as evidenced by higher odds of being in the minimal-impact-resilience and recovery trajectories.
Conclusion
Family caregivers’ distinct depressive-symptom trajectories were linked to their preloss caregiving demands, appraisal of negative caregiving impact, personal coping capacity, and perceived social support. Our results highlight actionable opportunities to improve end-of-life-care quality by boosting family caregivers’ coping capacity and enhancing their social support to help them adequately manage daily caregiving loads/burdens thus relieving the emotional toll before patient death and throughout bereavement.

The scarce research on factors associated with surrogate decisional regret overlooks longitudinal, heterogenous decisional-regret experiences and fractionally examines factors from the three ...decision-process framework stages: decision antecedents, decision-making process, and decision outcomes. This study aimed to fill these knowledge gaps by focusing on factors modifiable by high-quality end-of-life (EOL) care.
This observational study used a prior cohort of 377 family surrogates of terminal-cancer patients to examine factors associated with their membership in the four preidentified distinct decisional-regret trajectories: resilient, delayed-recovery, late-emerging, and increasing-prolonged trajectories from EOL-care decision making through the first two bereavement years by multinomial logistic regression modeling using the resilient trajectory as reference.
Decision antecedent factors: Financial sufficiency and heavier caregiving burden increased odds for the delayed-recovery trajectory. Spousal loss, higher perceived social support during an EOL-care decision, and more postloss depressive symptoms increased odds for the late-emerging trajectory. More pre- and postloss depressive symptoms increased odds for the increasing-prolonged trajectory. Decision-making process factors: Making an anticancer treatment decision and higher decision conflict increased odds for the delayed-recovery and increasing-prolonged trajectories. Making a life-sustaining-treatment decision increased membership in the three more profound trajectories. Decision outcome factors: Greater surrogate appraisal of quality of dying and death lowered odds for the three more profound trajectories. Patient receipt of anticancer or life-sustaining treatments increased odds for the late-emerging trajectory.
Surrogate membership in decisional-regret trajectories was associated with decision antecedent, decision-making process, and decision outcome factors. Effective interventions should target identified modifiable factors to address surrogate decisional regret.

Regret plays a central role in surrogate decision making. Research on decisional regret in family surrogates is scarce and lacks longitudinal studies to illustrate the heterogenous, dynamic evolution ...of decisional regret.
To identify distinct decisional-regret trajectories from end-of-life (EOL) decision making through the first two bereavement years among surrogates of cancer patients.
A prospective, longitudinal, observational study was conducted on a convenience sample of 377 surrogates of terminally ill cancer patients. Decisional regret was measured by the five-item Decision Regret Scale monthly during the patient's last six months and 1, 3, 6, 13, 18, and 24 months post loss. Decisional-regret trajectories were identified using latent-class growth analysis.
Surrogates reported substantially high decisional regret (pre- and postloss mean SD as 32.20 11.47 and 29.90 12.47, respectively). Four decisional-regret trajectories were identified. The resilient trajectory (prevalence: 25.6%) showed a general low decisional-regret level with mild and transient perturbations around the time of patient death only. Decisional regret for the delayed-recovery trajectory (56.3%) accelerated before the patient's death and decreased slowly throughout bereavement. Surrogates in the late-emerging (10.2%) trajectory reported a low decisional-regret level before loss but their decisional regret increased gradually thereafter. The increasing-prolonged trajectory (6.9%) rapidly increased in decisional-regret levels during EOL decision making, peaked one-month post loss, then declined steadily but without a complete resolution.
Surrogates heterogeneously suffered decisional regret from EOL decision making through bereavement as evident by four identified distinct decisional-regret trajectories. Early identification and prevention of increasing/prolonged decisional-regret trajectories is warranted.

Preparing family caregivers, cognitively, emotionally, and behaviorally, for their relative's death is an actionable component of high-quality end-of-life care. We aimed to examine the ...never-before-examined associations of conjoint cognitive prognostic awareness and emotional preparedness for death with caregiving outcomes and end-of-life care received by cancer patients.
For this longitudinal study, associations of death-preparedness states (no-death-preparedness, cognitive-death-preparedness-only, emotional-death-preparedness-only, and sufficient-death-preparedness states) with subjective caregiving burden, depressive symptoms, and quality of life (QOL) and patients’ end-of-life care (chemotherapy and/or immunotherapy, cardiopulmonary resuscitation, intensive care unit care, intubation, mechanical ventilation support, vasopressors, nasogastric tube feeding, and hospice care) were evaluated using multivariate hierarchical linear and logistic regression modeling, respectively, for 377 caregivers in cancer patients’ last 6 months and 1 month, respectively.
Caregivers in the cognitive-death-preparedness-only state experienced a higher level of subjective caregiving burden than those in the sufficient-death-preparedness state. Caregivers in the no-death-preparedness and cognitive-death-preparedness-only states reported significantly more depressive symptoms and worse QOL than those in the sufficient-death-preparedness state. Cancer patients with caregivers in the sufficient-death-preparedness state were less likely to receive chemotherapy and/or immunotherapy, intubation, mechanical ventilation, and nasogastric tube feeding than patients with caregivers in other death-preparedness states. However, patients’ receipt of hospice care was not associated with their caregivers’ death-preparedness states.
Family caregivers’ death-preparedness states were associated with caregiving outcomes and their relative's end-of-life care. Cultivating caregivers’ accurate prognostic awareness and improving their emotional preparedness for their relative's death may facilitate more favorable end-of-life-caregiving outcomes and may limit potentially nonbeneficial end-of-life care.

Family surrogates experience heterogeneous decisional regret and negative long-lasting postdecision impacts. Cross-sectional findings on the associations between decisional regret and surrogates' ...bereavement outcomes are conflicting and cannot illustrate the directional and dynamic evolution of these associations. In this study, we sought to longitudinally examine the associations between 4 previously identified decisional-regret trajectories and bereavement outcomes among family surrogates of terminally ill patients with cancer.
This prospective, longitudinal, observational study included 377 family surrogates. Decisional regret was measured using the 5-item Decision Regret Scale, and 4 decisional regret trajectories were identified: resilient, delayed-recovery, late-emerging, and increasing-prolonged. Associations between bereavement outcomes (depressive symptoms, prolonged grief symptoms, and physical and mental health-related quality of life HRQoL) and decisional-regret trajectories were examined simultaneously by multivariate hierarchical linear modeling using the resilient trajectory as a reference.
Surrogates in the delayed-recovery, late-emerging, and increasing-prolonged trajectories experienced significantly higher symptoms of prolonged grief (β 95% CI, 1.815 0.782 to 2.848; 2.312 0.834 to 3.790; and 7.806 2.681 to 12.931, respectively) and poorer physical HRQoL (-1.615 -2.844 to -0.386; -1.634 -3.226 to -0.042; and -4.749 -9.380 to -0.118, respectively) compared with those in the resilient trajectory. Membership in the late-emerging and increasing-prolonged trajectories was associated with higher symptoms of depression (β 95% CI, 2.942 1.045 to 4.839 and 8.766 2.864 to 14.668, respectively), whereas only surrogates in the increasing-prolonged decisional-regret trajectory reported significantly worse mental HRQoL (-4.823 -8.216 to -1.430) than those in the resilient trajectory.
Surrogates who experienced delayed-recovery, unresolved, or late-emerging decisional regret may carry ceaseless doubt, guilt, or self-blame for patient suffering, leading to profound symptoms of prolonged grief, depressive symptoms, and worse HRQoL over their first 2 bereavement years.
Half of advanced cancer patients do not have accurate prognostic awareness (PA). However, few randomized clinical trials (RCTs) have focused on facilitating patients' PA to reduce their ...life-sustaining treatments at end of life (EOL). To address these issues, we conducted a double-blinded RCT on terminally ill cancer patients.
Experimental-arm participants received an individualized, interactive intervention tailored to their readiness for advanced care planning and prognostic information. Control-arm participants received a symptom-management educational treatment. Effectiveness of our intervention in facilitating accurate PA and reducing life-sustaining treatments received, two secondary RCT outcomes, was evaluated by intention-to-treat analysis using multivariate logistic regression.
Participants (N = 460) were randomly assigned 1:1 to experimental and control arms, each with 215 participants in the final sample. Referring to 151–180 days before death, experimental-arm participants had significantly higher odds of accurate PA than control-arm participants 61–90, 91–120, and 121–150 days before death (adjusted odds ratio 95% CI: 2.04 1.16–3.61, 1.94 1.09–3.45, and 1.93 1.16–3.21, respectively), but not one to 60 days before death. Experimental-arm participants with accurate PA were significantly less likely than control-arm participants without accurate PA to receive cardiopulmonary resuscitation (CPR) (0.16 0.03–0.73), but not less likely to receive intensive care unit care and mechanical ventilation in their last month.
Our intervention facilitated cancer patients' accurate PA early in their dying trajectory, reducing the risk of receiving CPR in the last month. Health care professionals should cultivate cancer patients' accurate PA early in the terminal-illness trajectory to allow them sufficient time to make informed EOL-care decisions to reduce CPR at EOL.

Family caregivers’ distinct depressive-symptom trajectories are understudied and have been examined independently during end-of-life (EOL) caregiving or bereavement, making it difficult to validate ...two competing hypotheses (wear-and-tear vs. relief) of caregiving effects on bereavement. Existing studies may also miss short-term heterogeneity in depressive symptoms during the immediate postloss period due to lengthy delays in the first postloss assessment.
This secondary-analysis study examined distinct depressive-symptom trajectories for caregivers of advanced cancer patients from EOL caregiving through the first 2 bereavement years with closely spaced assessments.
Depressive symptoms were measured monthly during EOL caregiving and 1, 3, 6, 13, 18, and 24 months postloss among 661 caregivers using the Center for Epidemiologic Studies-Depression scale. Depressive-symptom trajectories were identified using latent-class growth analysis while controlling for gender and age.
We identified seven distinct depressive-symptom trajectories (prevalence) characterized by the timing, intensity, and duration of depressive symptoms: minimal-impact resilience (20.4%), recovery (34.0%), preloss-grief only (21.6%), delayed symptomatic (9.1%), relief (5.9%), prolonged symptomatic (6.5%), and chronically persistent distressed (2.5%).
Caregivers of advanced cancer patients responded heterogeneously to the stresses of EOL caregiving and bereavement. The majority of caregivers was resilient while providing caregiving and quickly rebounded to healthy levels of psychological functioning during bereavement, whereas a minority experienced delayed-symptomatic, prolonged-symptomatic, or chronically-persistent-distressing depressive-symptom trajectories. Linking caregivers’ psychological experiences from caregiving through bereavement by closely spaced assessments can more comprehensively illustrate their depressive-symptom trajectories, which confirm both the wear-and-tear and relief hypotheses, and help in targeting interventions for distinct depressive-symptom trajectories.
