Concurrent Atezolizumab Plus Bevacizumab and High-Dose External Beam Radiotherapy for Highly Advanced Hepatocellular Carcinoma.

BACKGROUND: Atezolizumab plus bevacizumab (atezo-bev) has been recommended for advanced hepatocellular carcinoma (HCC). High-dose external beam radiotherapy (RT) is recognized for its excellent local tumor control. The efficacy and safety of concurrent atezo-bev with RT for highly advanced HCC has been minimally explored. METHODS: In this preliminary retrospective study, we assessed patients with highly advanced HCC, characterized by Vp4 portal vein thrombosis or tumors exceeding 50% of liver volume, who received concurrent atezo-bev and RT (group A). Group A included 13 patients who received proton radiation at a dose of 72.6 GyE in 22 fractions, and one patient who received photon radiation at a dose of 54 Gy in 18 fractions. This group was compared with 34 similar patients treated atezo-bev alone as a control (group B). The primary objectives were to evaluate the objective response rate (ORR), overall survival (OS), and safety. RESULTS: Baseline characteristics were similar between groups, except for a higher incidence of Vp4 portal vein thrombosis in group A (78.6% vs. 21.4%, P = .05). Group A achieved a higher ORR (50.0% vs. 11.8%, P < .01) and a longer OS (not reached vs. 5.5 months, P = .01) after a median follow-up of 5.2 months. Multivariate analysis indicated that concurrent RT independently favored longer OS (hazard ratio: 0.18; 95% CI, 0.05-0.63, P < .01). Group A did not increase any grade adverse events (78.6% vs. 58.8%, P = .19) or severe adverse events of grade ≥ 3 (14.3% vs. 14.7%, P = .97) compared to group B. CONCLUSIONS: The concurrent high-dose external beam radiotherapy appears to safely enhance the effectiveness of atezolizumab plus bevacizumab for highly advanced patients with HCC. Further studies are warranted to confirm these findings.

Temporal Trends in Survival Outcomes for Patients with Esophageal Cancer Following Neoadjuvant Chemoradiotherapy: A 14-Year Analysis.

BACKGROUND: The prognosis for patients with esophageal cancer who received neoadjuvant chemoradiotherapy (nCRT) followed by surgery has shown improvement in recent years. We sought to identify the critical factors contributing to enhanced survival outcomes. PATIENTS AND METHODS: We retrospectively examined 427 patients with esophageal cancer treated with nCRT and esophagectomy across two periods: P1 (from 1 January 2004 to 31 December 2011) and P2 (from 1 January 2012 to 31 December 2017). The introduction of the CROSS regimen and total meso-esophagectomy in P2 prompted an evaluation of their effects on perioperative outcomes and overall survival (OS). RESULTS: During P2, the occurrence of recurrent laryngeal nerve palsy increased significantly from 3.9 to 16.8% (p < 0.001), while pneumonia and in-hospital mortality rates remained unchanged. The median OS improved from 19.2 to 29.2 months (p < 0.001) between P1 and P2. Multivariable analysis identified higher nodal yields and the achievement of major response as favorable prognostic factors. Conversely, an involved circumferential resection margin (CRM), an advanced ypN stage, and pneumonia were independently associated with poor outcomes. Patients treated during P2 had a lower prevalence of involved CRM (10% vs. 25.1%, p < 0.001), a higher rate of major response (52.7% vs. 34.8%, p < 0.01), and a greater nodal yield (27.8 vs. 10.9, p < 0.001). CONCLUSIONS: The clinical outcomes following nCRT and surgery have improved significantly over time. This progress can be attributed to multiple factors, with the primary drivers being the refinement of nCRT protocols and the application of radical surgery.

Factors of preparedness for loss from cancer among Taiwanese family caregivers.

This cohort study investigated factors associated with 336 Taiwanese family caregivers' emotional and cognitive preparedness for death of a loved one with terminal cancer. Caregivers' death-preparedness states (no-death-preparedness [as reference], cognitive-death-preparedness-only, emotional-death-preparedness-only, and sufficient-death-preparedness states) were previously identified. Associations of factors with these states were determined by a hierarchical generalized linear model. Financial hardship decreased caregivers' likelihood for the emotional-death-preparedness-only and sufficient-death-preparedness states. Physician prognostic disclosure increased membership in the cognitive-death-preparedness-only and sufficient-death-preparedness states. The better the quality of the patient-caregiver relationship, the higher the odds for the emotional-death-preparedness-only and sufficient-death-preparedness states, whereas the greater the tendency for caregivers to communicate end-of-life issues with their loved one, the lower the odds for emotional-death-preparedness-only state membership. Stronger coping capacity increased membership in the emotional-death-preparedness-only state, but perceived social support was not associated with state membership. Providing effective interventions tailored to at-risk family caregivers' specific needs may facilitate their death preparedness.

Associations Between Surrogates' Decisional Regret Trajectories and Bereavement Outcomes.

BACKGROUND: 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. PATIENTS AND METHODS: 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. RESULTS: Surrogates in the delayed-recovery, late-emerging, and increasing-prolonged trajectories experienced significantly higher symptoms of prolonged grief (ß [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 (ß [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. CONCLUSIONS: 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.

Factors associated with cancer patients' distinct death-preparedness states.

BACKGROUND/OBJECTIVE: Facilitating death preparedness is important for improving cancer patients' quality of death and dying. We aimed to identify factors associated with the four death-preparedness states (no-preparedness, cognitive-only, emotional-only, and sufficient-preparedness) focusing on modifiable factors. METHODS: In this cohort study, we identified factors associated with 314 Taiwanese cancer patients' death-preparedness states from time-invariant socio-demographics and lagged time-varying modifiable variables, including disease burden, physician prognostic disclosure, patient-family communication on end-of-life (EOL) issues, and perceived social support using hierarchical generalized linear modeling. RESULTS: Patients who were male, older, without financial hardship to make ends meet, and suffered lower symptom distress were more likely to be in the emotional-only and sufficient-preparedness states than the no-death-preparedness-state. Younger age (adjusted odds ratio [95% confidence interval] = 0.95 [0.91, 0.99] per year increase in age) and greater functional dependency (1.05 [1.00, 1.11]) were associated with being in the cognitive-only state. Physician prognostic disclosure increased the likelihood of being in the cognitive-only (51.51 [14.01, 189.36]) and sufficient-preparedness (47.42 [10.93, 205.79]) states, whereas higher patient-family communication on EOL issues reduced likelihood for the emotional-only state (0.38 [0.21, 0.69]). Higher perceived social support reduced the likelihood of cognitive-only (0.94 [0.91, 0.98]) but increased the chance of emotional-only (1.09 [1.05, 1.14]) state membership. CONCLUSIONS: Death-preparedness states are associated with patients' socio-demographics, disease burden, physician prognostic disclosure, patient-family communication on EOL issues, and perceived social support. Providing accurate prognostic disclosure, adequately managing symptom distress, supporting those with higher functional dependence, promoting empathetic patient-family communication on EOL issues, and enhancing perceived social support may facilitate death preparedness.

Transdermal buprenorphine improves overall quality of life and symptom severity in cancer patients with pain.

AIM AND OBJECTIVES: This study explored the effect of transdermal buprenorphine on quality of life and six symptoms in cancer patients with pain. BACKGROUND: Transdermal opioids offer advantages over traditional routes of administration. The impact of transdermal buprenorphine on quality of life for patients with cancer in Asian populations is unknown. DESIGN: This study employed a single-arm observational repeated measures design. Cancer patients with pain were evaluated prior to treatment (baseline). Over a 4-week treatment period, quality of life and symptoms were assessed at 2 and 4 weeks. This study adhered to the recommendations of STROBE guidelines. METHODS: This multi-site study was conducted in six hospitals located across northern, middle and southern Taiwan. Adult cancer patients whose pain was previously stable with opioid analgesics and, based on clinical judgement, were able to convert to transdermal buprenorphine treatment were invited to participate. Quality of life was measured with the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30). RESULTS: Generalised estimating equations showed participants who completed at least one follow-up measurement (N = 80) over 4-weeks had a significant improvement in overall quality of life. Functional status only improved for social functioning. However, symptom severity decreased significantly for nausea/vomiting, pain, insomnia and constipation. CONCLUSIONS: The study provides initial evidence supporting transdermal buprenorphine for providing beneficial effects of improving quality of life and reducing severity of symptoms in Asian patients with cancer. RELEVANCE TO CLINICAL PRACTICE: The findings of this study can inform the clinical practice that the use of transdermal buprenorphine in cancer patients with pain may also reduce the severity of other symptoms and improve overall quality of life. TRIAL REGISTRATION DETAILS: This study was registered in ClinicalTrials.gov. Identifier: NCT04315831.

Associations of surrogates' death-preparedness states with decisional conflict and heightened decisional regret over cancer patients' last 6 months of life.

OBJECTIVE: Preparing family surrogates for patient death and end-of-life (EOL) decision making may reduce surrogate decisional conflict and regret. Preparedness for patient death involves cognitive and emotional preparedness. We assessed the associations of surrogates' death-preparedness states (that integrate both cognitive and emotional preparedness for patient death) with surrogates' decisional conflict and regret. METHODS: Associations of 173 surrogates' death-preparedness states (no, cognitive-only, emotional-only, and sufficient preparedness states) with decisional conflict (measured by the Decision Conflict Scale) and heightened decisional regret (Decision Regret Scale scores >25) were evaluated using hierarchical linear modeling and hierarchical generalized linear modeling, respectively, during a longitudinal observational study at a medical center over cancer patients' last 6 months. RESULTS: Surrogates reported high decisional conflict (mean [standard deviation] = 41.48 [6.05]), and 52.7% of assessments exceeded the threshold for heightened decisional regret. Surrogates in the cognitive-only preparedness state reported a significantly higher level of decisional conflict (ß = 3.010 [95% CI = 1.124, 4.896]) than those in the sufficient preparedness state. Surrogates in the no (adjusted odds ratio [AOR] [95% CI] = 0.293 [0.113, 0.733]) and emotional-only (AOR [95% CI] = 0.359 [0.149, 0.866]) preparedness states were less likely to suffer heightened decisional regret than those in the sufficient preparedness state. CONCLUSIONS: Surrogates' decisional conflict and heightened decisional regret are associated with their death-preparedness states. Improving emotional preparedness for the patient's death among surrogates in the cognitive-only preparedness state and meeting the specific needs of those in the no, emotional-only, and sufficient preparedness states are actionable high-quality EOL-care interventions that may lessen decisional conflict and decisional regret.

Associations of death-preparedness states with bereavement outcomes for family caregivers of terminally ill cancer patients.

OBJECTIVE: Death preparedness involves cognitive prognostic awareness and emotional acceptance of a relative's death. Effects of retrospectively assessed cognitive prognostic awareness and emotional preparedness for patient death have been individually investigated among bereaved family caregivers. We aimed to prospectively examine associations of caregivers' death-preparedness states, determined by conjoint cognitive prognostic awareness and emotional preparedness for death, with bereavement outcomes. METHODS: Associations of caregivers' death-preparedness states (no-death-preparedness, cognitive-death-preparedness-only, emotional-death-preparedness-only, and sufficient-death-preparedness states) at last preloss assessment with bereavement outcomes over the first two bereavement years were evaluated among 332 caregivers of advanced cancer patients using hierarchical linear models with the logit-transformed posterior probability for each death-preparedness state. RESULTS: Caregivers with a higher logit-transformed posterior probability for sufficient death-preparedness state reported less prolonged-grief symptoms, lower likelihoods of severe depressive symptoms and heightened decisional regret, and better mental health-related quality of life (HRQOL). Caregivers with a higher logit-transformed posterior probability for no-death-preparedness state reported less prolonged-grief symptoms, a lower likelihood of severe depressive symptoms, and better mental HRQOL. A higher logit-transformed posterior probability for cognitive-death-preparedness-only state was associated with bereaved caregivers' higher likelihood of heightened decisional regret, whereas that for emotional-death-preparedness-only state was not associated with caregivers' bereavement outcomes. CONCLUSIONS: Caregivers' bereavement outcomes were associated with their preloss death-preparedness states, except for physical health-related QOL. Interventions focused on not only cultivating caregivers' accurate prognostic awareness but also adequately preparing them emotionally for their relative's forthcoming death are actionable opportunities for high-quality end-of-life care and are urgently warranted to facilitate caregivers' bereavement adjustment.

Modifiable factors of depressive-symptom trajectories from caregiving through bereavement.

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.

Phase I first-in-human study of HLX07, a novel and improved recombinant anti-EGFR humanized monoclonal antibody, in patients with advanced solid cancers.

Purpose This study aimed to evaluate the safety and pharmacokinetic (PK) profiles of HLX07, a novel, recombinant, humanized anti-epidermal growth factor receptor (EGFR) antibody, in patients with advanced solid cancers who had failed standard therapy or for whom no standard therapy was available. Methods In this prospective, open-label, Phase I dose escalation study, patients aged ≥18 years (≥20 years for patients in Taiwan) with histologically-confirmed metastatic or recurrent epithelial carcinoma that had no K-RAS or B-RAF mutations were enrolled in a '3 + 3' escalation design. HLX07 was administered weekly by 2-h intravenous infusion at doses ranging from 50 to 800 mg. The primary endpoint was summary listing of participants reporting treatment-emergent adverse events (TEAEs). Secondary endpoints included PK analysis, serum anti-HLX07 antibody assessments and efficacy. Results In total, 19 patients were enrolled between 1 October 2016 and 16 July 2019 to receive HLX07 at doses of 50 (n = 3), 100 (n = 3), 200 (n = 3), 400 (n = 3), 600 (n = 3) and 800 (n = 4) mg per week. All patients experienced at least one TEAE, most commonly fatigue (68.4%), nausea (47.4%), paronychia (31.6%) and vomiting (31.6%). Serious TEAEs were reported in 11 patients but only one serious TEAE (dyspnea in 600 mg cohort) was regarded as possibly related to study treatment. No dose limiting toxicity (DLT) was reported. Systemic exposure to HLX07 increased proportionally with dose. Anti-HLX07 antibodies were not detected in any patients. Conclusion HLX07 was well tolerated (at dose levels up to 800 mg/week) and promising in patients with advanced solid cancers.Clinical Trial Registration: The study was registered at ClinicalTrials.gov : NCT02648490 (Jan 7, 2016).

Accuracy of detecting residual disease after neoadjuvant chemoradiotherapy for esophageal squamous cell carcinoma (preSINO trial): a prospective multicenter diagnostic cohort study.

BACKGROUND: After neoadjuvant chemoradiotherapy (nCRT) for esophageal cancer, high pathologically complete response (pCR) rates are being achieved especially in patients with squamous cell carcinoma (SCC). An active surveillance strategy has been proposed for SCC patients with clinically complete response (cCR) after nCRT. To justify omitting surgical resection, patients with residual disease should be accurately identified. The aim of this study is to assess the accuracy of response evaluations after nCRT based on the preSANO trial, including positron emission tomography with computed tomography (PET-CT), endoscopy with bite-on-bite biopsies and endoscopic ultrasonography (EUS) with fine-needle aspiration (FNA) in patients with potentially curable esophageal SCC. METHODS: Operable esophageal SCC patients who are planned to undergo nCRT according to the CROSS regimen and are planned to undergo surgery will be recruited from four Asian centers. Four to 6 weeks after completion of nCRT, patients will undergo a first clinical response evaluation (CRE-1) consisting of endoscopy with bite-on-bite biopsies. In patients without histological evidence of residual tumor (i.e. without positive biopsies), surgery will be postponed another 6 weeks. A second clinical response evaluation (CRE-2) will be performed 10-12 weeks after completion of nCRT, consisting of PET-CT, endoscopy with bite-on-bite biopsies and EUS with FNA. Immediately after CRE-2 all patients without evidence of distant metastases will undergo esophagectomy. Results of CRE-1 and CRE-2 as well as results of the three single diagnostic modalities will be correlated to pathological response in the resection specimen (gold standard) for calculation of sensitivity, specificity, negative predictive value and positive predictive value. DISCUSSION: If the current study shows that major locoregional residual disease (> 10% residual carcinoma or any residual nodal disease) can be accurately (i.e. with sensitivity of 80.5%) detected in patients with esophageal SCC, a prospective trial will be conducted comparing active surveillance with standard esophagectomy in patients with a clinically complete response after nCRT (SINO trial). TRIAL REGISTRATION: The preSINO trial has been registered at ClinicalTrials.gov as NCT03937362 (May 3, 2019).

Nivolumab in advanced hepatocellular carcinoma: Sorafenib-experienced Asian cohort analysis.

BACKGROUND & AIMS: Nivolumab, an immune checkpoint inhibitor, is approved in several countries to treat sorafenib-experienced patients with HCC, based on results from the CheckMate 040 study (NCT01658878). Marked differences exist in HCC clinical presentation, aetiology, treatment patterns and outcomes across regions. This analysis assessed the safety and efficacy of nivolumab in the Asian cohort of CheckMate 040. METHODS: CheckMate 040 is an international, multicentre, open-label, phase I/II study of nivolumab in adults with advanced HCC, regardless of aetiology, not amenable to curative resection or local treatment and with/without previous sorafenib treatment. This analysis included all sorafenib-experienced patients in the intent-to-treat (ITT) overall population and Asian cohort. The analysis cut-off date was March 2018. RESULTS: There were 182 and 85 patients in the ITT population and Asian cohort, respectively. In both populations, most patients were older than 60 years, had BCLC (Barcelona Clinic Liver Cancer) Stage C disease, and had received previous systemic therapy. A higher percentage of Asian patients had HBV infections, extrahepatic metastases and prior therapies. Median follow-up was 31.6 and 31.3 months for the ITT and Asian patients, respectively. Objective response rates were 14% and 15% in the ITT population and Asian cohort, respectively. In the Asian cohort, patients with HBV, HCV or those who were uninfected had objective response rates of 13%, 14% and 21%, respectively. The median duration of response was longer in the ITT (19.4 months) vs. Asian patients (9.7 months). Median overall survival was similar between the ITT (15.1 months) and Asian patients (14.9 months), and unaffected by aetiology in Asian patients. The nivolumab safety profile was similar and manageable across both populations. CONCLUSION: Nivolumab safety and efficacy are comparable between sorafenib-experienced ITT and Asian patients. LAY SUMMARY: The CheckMate 040 study evaluated the safety and efficacy of nivolumab in patients with advanced hepatocellular carcinoma who were refractory to previous sorafenib treatment or chemotherapy. This subanalysis of the data showed that treatment responses and safety in patients in Asia were similar to those of the overall treatment population, providing support for nivolumab as a treatment option for these patients. Clinical trial number: NCT01658878.

Changes in and modifiable patient- and family caregiver-related factors associated with cancer patients' high self-perceived burden to others at the end of life: A longitudinal study.

This prospective, longitudinal study explored changes in and modifiable factors associated with high self-perceived burden to others (SPB) among a convenience sample of 276 dyads of terminally ill Taiwanese cancer patients and their family caregivers over patients' last year of life. High SPB was evaluated by scores ≥20 on the Self-Perceived Burden Scale. Modifiable factors of high SPB included factors related to both patients (i.e., symptom distress, functional dependence and coping capacity) and caregivers (i.e., caregiving burden, depressive symptoms and quality of life [QOL]). Modifiable factors of high SPB were identified by multivariate logistic regression modelling with the generalised estimating equation while controlling for demographic factors. We found that patients tended to experience high SPB if they had more symptom distress. In contrast, the likelihood of high SPB was significantly lower if patients had greater coping capacity and their caregivers reported better QOL. High SPB was not associated with patients' functional dependence, caregivers' caregiving burden and depressive-symptom level while providing end-of-life (EOL) care, and time proximity to death. Healthcare professionals may alleviate terminally ill cancer patients' high SPB at EOL through palliative care that adequately manages patients' physical symptom distress, enhances patients' coping capacity and improves family caregivers' QOL.

Changes in serum α-fetoprotein level predicts treatment response and survival in hepatocellular carcinoma patients and literature review.

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.

Transitions in Prognostic Awareness Among Terminally Ill Cancer Patients in Their Last 6 Months of Life Examined by Multi-State Markov Modeling.

BACKGROUND: Developing accurate prognostic awareness, a cornerstone of preference-based end-of-life (EOL) care decision-making, is a dynamic process involving more prognostic-awareness states than knowing or not knowing. Understanding the transition probabilities and time spent in each prognostic-awareness state can help clinicians identify trigger points for facilitating transitions toward accurate prognostic awareness. We examined transition probabilities in distinct prognostic-awareness states between consecutive time points in 247 cancer patients' last 6 months and estimated the time spent in each state. METHODS: Prognostic awareness was categorized into four states: (a) unknown and not wanting to know, state 1; (b) unknown but wanting to know, state 2; (c) inaccurate awareness, state 3; and (d) accurate awareness, state 4. Transitional probabilities were examined by multistate Markov modeling. RESULTS: Initially, 59.5% of patients had accurate prognostic awareness, whereas the probabilities of being in states 1-3 were 8.1%, 17.4%, and 15.0%, respectively. Patients' prognostic awareness generally remained unchanged (probabilities of remaining in the same state: 45.5%-92.9%). If prognostic awareness changed, it tended to shift toward higher prognostic-awareness states (probabilities of shifting to state 4 were 23.2%-36.6% for patients initially in states 1-3, followed by probabilities of shifting to state 3 for those in states 1 and 2 [9.8%-10.1%]). Patients were estimated to spend 1.29, 0.42, 0.68, and 3.61 months in states 1-4, respectively, in their last 6 months. CONCLUSION: Terminally ill cancer patients' prognostic awareness generally remained unchanged, with a tendency to become more aware of their prognosis. Health care professionals should facilitate patients' transitions toward accurate prognostic awareness in a timely manner to promote preference-based EOL decisions. IMPLICATIONS FOR PRACTICE: Terminally ill Taiwanese cancer patients' prognostic awareness generally remained stable, with a tendency toward developing higher states of awareness. Health care professionals should appropriately assess patients' readiness for prognostic information and respect patients' reluctance to confront their poor prognosis if they are not ready to know, but sensitively coach them to cultivate their accurate prognostic awareness, provide desired and understandable prognostic information for those who are ready to know, and give direct and honest prognostic information to clarify any misunderstandings for those with inaccurate awareness, thus ensuring that they develop accurate and realistic prognostic knowledge in time to make end-of-life care decisions.

Impact of high self-perceived burden to others with preferences for end-of-life care and its determinants for terminally ill cancer patients: a prospective cohort study.

BACKGROUND/OBJECTIVE: Self-perceived burden to others (SPB) is a major concern of terminally ill cancer patients and is frequently factored into end-of-life (EOL) care decision-making. However, changes in and determinants of SPB and its longitudinal impact on preferences for EOL care over the dying process have not been investigated. Our study was aimed at filling this gap in knowledge. METHODS: A convenience sample of 325 cancer patients was followed until death. High SPB was identified as scoring >20 on the Self-perceived Burden Scale. Preferences for EOL care included EOL-care goals, life-sustaining treatments, and hospice care. Factors potentially precipitating/minimizing patients' high SPB included demographics, disease characteristics and burden, and social support and were examined by multivariate logistic regression modeling with the generalized estimating equation. RESULTS: Prevalence of high SPB increased as death approached (51.78%, 58.26%, 62.66%, and 65.38% for 181-365, 91-180, 31-90, and 1-30 days before death, respectively). High SPB was precipitated by women, younger age, having inadequate financial resources, without religious affiliation, and suffering from severe symptom distress and heavy functional dependence but was independent of time proximity to patient death, disease characteristics, and social support. Furthermore, high SPB was not associated with EOL-care preferences, whether aggressive life-sustaining treatments or hospice care. CONCLUSIONS: High SPB was prevalent among terminally ill cancer patients but independent of preferences for EOL care. Cancer patients' SPB may be lessened by adequate symptom relief to facilitate functional independence. These strategies to ease SPB may improve the quality of death and dying.

TLG-S criteria are superior to both EORTC and PERCIST for predicting outcomes in patients with metastatic lung adenocarcinoma treated with erlotinib.

PURPOSE: In this retrospective review of prospectively collected data, we sought to investigate whether early FDG-PET assessment of treatment response based on total lesion glycolysis measured using a systemic approach (TLG-S) would be superior to either local assessment with EORTC (European Organization for Research and Treatment of Cancer) criteria or single-lesion assessment with PERCIST (PET Response Criteria in Solid Tumors) for predicting clinical outcomes in patients with metastatic lung adenocarcinoma treated with erlotinib. We also examined the effect of bone flares on tumor response evaluation by single-lesion assessment with PERCIST in patients with metastatic bone lesions. METHODS: We performed a retrospective review of prospectively collected data from 23 patients with metastatic lung adenocarcinoma treated with erlotinib. All participants underwent FDG-PET imaging at baseline and on days 14 and 56 after completion of erlotinib treatment. In addition, diagnostic CT scans were performed at baseline and on day 56. FDG-PET response was assessed with TLG-S, EORTC, and PERCIST criteria. Response assessment based on RECIST 1.1 (Response Evaluation Criteria in Solid Tumors) from diagnostic CT imaging was used as the reference standard. Two-year progression-free survival (PFS) and overall survival (OS) served as the main outcome measures. RESULTS: We identified 13 patients with bone metastases. Of these, four (31 %) with persistent bone uptake due to bone flares on day 14 were erroneously classified as non-responders according to the PERCIST criteria, but they were correctly classified as responders according to both the EORTC and TLG-S criteria. Patients who were classified as responders on day 14 based on TLG-S criteria had higher rates of 2-year PFS (26.7 % vs. 0 %, P = 0.007) and OS (40.0 % vs. 7.7 %, P = 0.018). Similar rates were observed in patients who showed a response on day 56 based on CT imaging according to the RECIST criteria. Patients classified as responders on day 14 according to the EORTC criteria on FDG-PET imaging had better rates of 2-year OS than did non-responders (36.4 % vs. 8.3 %, P = 0.015). CONCLUSIONS: TLG-S criteria may be of greater help in predicting survival outcomes than other forms of assessment. Bone flares, which can interfere with the interpretation of treatment response based on PERCIST criteria, are not uncommon in patients with metastatic lung adenocarcinoma treated with erlotinib.

Cytoplasmic and nuclear parathyroid hormone-related proteins are opposing prognostic factors in patients with non-small-cell lung cancer who have undergone curative resection.

OBJECTIVE: Parathyroid hormone-like related protein was a prognostic factor for non-small-cell lung cancer, but the results were conflicting. The present study was to examine the role of cytoplasmic and nuclear parathyroid hormone-like related protein in patients with non-small-cell lung cancer who have undergone surgical therapy. METHODS: The expression of parathyroid hormone-like related protein was examined by immunohistochemical staining in 56 patients with resectable non-small-cell lung cancer. The impact of parathyroid hormone-like related protein expression on cancer recurrence and survival was assessed in combination with clinicopathologic features. RESULTS: Patients with a high expression of cytoplasmic parathyroid hormone-like related protein had a significantly unfavorable prognosis in both disease-free survival (median 16.7 vs. 58.0 months, P = 0.029) and overall survival (median 31.6 months vs. not reached, P = 0.046). In contrast, the patients with high expression of nuclear parathyroid hormone-like related protein had favorable disease-free survival (median 35.1 vs. 19.9 months, P = 0.069) and a significantly better overall survival (median not reached vs. 36.9 months, P = 0.033). There was no correlation between the expression of cytoplasmic and nuclear parathyroid hormone-like related protein (P = 1.00). Furthermore, multivariate analysis using a Cox regression model confirmed that high expression of cytoplasmic parathyroid hormone-like related protein (disease-free survival, hazard ratio: 1.973, P = 0.079; overall survival, hazard ratio: 2.461, P = 0.067) and nuclear parathyroid hormone-like related protein (disease-free survival, hazard ratio: 0.436, P = 0.029; overall survival, hazard ratio: 0.375, P = 0.018) were independently prognostic factors for disease-free survival and overall survival. CONCLUSION: Cytoplasmic and nuclear parathyroid hormone-like related protein play opposing prognostic roles for the disease-free survival and overall survival of patients with early non-small-cell lung cancer who have undergone curative resection.

Exploratory study of carboplatin plus the copper-lowering agent trientine in patients with advanced malignancies.

PURPOSE: Preclinical data showed that trientine, a copper-lowering agent, re-sensitized cancer cells to carboplatin through enhanced human copper transporter 1 (hCtr1) -mediated platinum uptake. EXPERIMENTAL DESIGN: We studied carboplatin and trientine in patients (n = 55; 45 who had failed platinum) with advanced malignancies (Phase I, modified 3 + 3 design). RESULTS: The most common cancers were head and neck (n = 13), non-small cell lung (n = 10) and epithelial ovarian (n = 8). The median number of prior regimens was four. No dose-limiting toxicity or treatment-related deaths were observed at doses up to carboplatin AUC 6 given with trientine. Eight patients achieved stable disease (SD) ≥ 6 months (six platinum failures) and one patient with platinum-resistant ovarian cancer, partial response (PR) (total SD ≥ 6 months/PR = 9, 16.4 %). The mean nadir serum copper level in the nine patients with SD ≥ 6 months/PR was 0.55 µg/mL (95 % CI, 0.34-0.75) versus 1.22 µg/mL (95 % CI, 1.02-1.42) (p < 0.001) in 38 tested patients with progression. In patients who maintained their ceruloplasmin (major copper-carrying protein) levels at 5-15 mg/dL (n = 9), the median progression-free and overall survivals were 9.2 and 15.2 months versus 1.9 (p = 0.001) and 5.7 months (p = 0.033) in patients who did not (n = 38), respectively. CONCLUSIONS: The combination of a copper-lowering agent with carboplatin was well tolerated and associated with antitumor activity, especially in patients in whom copper and/or ceruloplasmin levels were lowered. Further investigation of this strategy for reversing platinum resistance is warranted.
