Management of cancer-related fatigue in Taiwan: an evidence-based consensus for screening, assessment and treatment.

BACKGROUND: Cancer-related fatigue is one of the most common and persistent issues experienced by cancer patients. Cancer-related fatigue is a distinct form of fatigue that is subjective, long-lasting and unalleviated by rest or sleep. Studies have shown that almost all cancer patients experience severe fatigue that disrupts the quality of life and physical function, but cancer-related fatigue remains under-addressed in clinical care, and only about half of all patients receive treatment. METHODS: To increase the awareness of cancer-related fatigue and improve current management, the Taiwan Society of Cancer Palliative Medicine and the Taiwan Oncology Nursing Society convened a consensus committee to develop recommendations for the screening, assessment and treatment of cancer-related fatigue. RESULTS: Thirteen consensus recommendations were subsequently developed based on the best available evidence and the clinical experience of committee members. CONCLUSIONS: These recommendations are expected to facilitate the standardization of cancer-related fatigue management across Taiwan and may also serve as a reference for other clinicians.

A nationwide survey of fatigue in cancer patients in Taiwan: an unmet need.

BACKGROUND: Cancer-related fatigue (CRF) is an emerging clinical issue, although its prevalence and impact on quality of life (QOL) in cancer patients in Taiwan remain unclear. The present nationwide cross-sectional study was conducted to provide a thorough overview of the prevalence, related factors and impact of CRF in Taiwan. METHODS: In this multi-center survey, data were collected using the International Classification of Diseases 10th Revision (ICD-10) Fatigue evaluation, Brief Fatigue Inventory-Taiwan (BFI-T), the Chinese version of the Symptom Distressed Scale and a fatigue experience survey. Logistic regression was used to determine the correlations between fatigue characteristics and the factors studied. RESULTS: A total of 1207 cancer patients were recruited from 23 hospitals in Taiwan. Fatigue was the most distressing symptom in Taiwanese cancer patients. The distress score was higher if CRF was diagnosed using ICD-10 compared with BFI-T. Rest and nutritional supplementation were the most common non-pharmacological treatments; blood transfusion was the most common pharmacological treatment. There were 45% of patients reported not receiving a timely intervention for fatigue. CONCLUSIONS: Fatigue is the most bothersome symptom reported by Taiwanese cancer patients. Caregivers should be aware of the impact of CRF on QOL in cancer patients, constantly measure the severity of fatigue and provide appropriate interventions.

Novel circulating tumor cell-based blood test for the assessment of PD-L1 protein expression in treatment-naïve, newly diagnosed patients with non-small cell lung cancer.

We evaluated the analytical and clinical performance of a novel circulating tumor cell (CTC)-based blood test for determination of programmed death ligand 1 (PD-L1) protein expression status in real time in treatment-naïve non-small cell lung cancer (NSCLC) patients. CTCs were detected in 86% of patients with NSCLC (I-IV) at the time of diagnosis, with a 67% PD-L1 positivity rate (≥ 1 PDL + CTC). Among 33 NSCLC patients with PD-L1 results available via both tissue immunohistochemistry (IHC) and CTC assays, 78.9% were positive according to both methods. The CTC test identified an additional ten cases that were positive for PD-L1 expression but that tested negative via IHC analysis. Detection of higher PD-L1 expression on CTCs compared to that in the corresponding tissue was concordant with data obtained using other platforms in previously treated patients. The concordance in PD-L1 expression between tissue and CTCs was approximately 57%, which is higher than that reported by others. In summary, evaluation of PD-L1 protein expression status on CTCs isolated from NSCLC patients is feasible. PD-L1 expression status on CTCs can be determined serially during the disease course, thus overcoming the myriad challenges associated with tissue analysis.

Patients with head and neck cancer may need more intensive pain management to maintain daily functioning: a multi-center study.

PURPOSE: The purpose of this study is to investigate the prevalence of pain, pain management, and impact of recent pain on daily functioning in patients with head and neck cancer (HNC) and patients with other cancers. METHODS: This multi-center survey was conducted by using Brief Pain Inventory questionnaire to evaluate pain status and its impact on daily functioning. RESULTS: A total of 3289 patients were analyzed including 708 HNC patients and 2581 patients with other cancers. The overall pain prevalence was 69.17%. A higher percentage of HNC patients had recent pain (60.59 vs. 44.01%, P < 0.001), required pain management (86.29 vs. 72.03%, P < 0.001), and used any analgesics (53.81 vs. 34.52%, P < 0.001). HNC patients with pain management had a higher prevalence of recent pain (85.83 vs. 81.14%, P = 0.044) and a slightly lower satisfaction rate (74.00 vs. 79.70%, P = 0.070). Regarding the impact of pain on daily functioning, HNC patients had a lower mean interference score for general activity such as walking, normal work, sleep, and life enjoyment. CONCLUSIONS: The HNC patients may need more intensive pain management to achieve optimal pain control and maintain daily functioning.

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.

Quality of life of breast and cervical cancer survivors.

BACKGROUND: Breast and cervical cancer are the most common cancers affecting women. The symptom distresses experienced by cancer survivors are critical factors influencing their quality of life (QOL). This study investigated the QOL of breast and cervical cancer survivors, their physical, psychological and social conditions. METHODS: The participants were older than 20 years, had been diagnosed with breast or cervical cancer for more than 2 years, and had completed their cancer treatment. The survey incorporated the QOL questionnaires developed by the European Organization of Research and Treatment for Cancer and a self-designed questionnaire. RESULTS: The mean age at diagnosis was 48.89 ± 8.53 years for the breast cancer survivors and 49.00 ± 10.30 years for the cervical cancer survivors. The corresponding QOL scores were 75.33 ± 20.25 and 75.56 ± 17.93. The factors influencing QOL of breast cancer survivors were household income, number of comorbidities, stage of cancer, type of cancer treatment and duration of illness, whereas the factor related to QOL of cervical cancer survivors was only household income. CONCLUSIONS: The QOL of the two groups was similar. Healthcare providers should demonstrate greater concern toward breast and cervical cancer survivors.

A phase I dose-escalation study of PEP02 (irinotecan liposome injection) in combination with 5-fluorouracil and leucovorin in advanced solid tumors.

BACKGROUND: PEP02 (also known as MM-398, nal-IRI) is a novel nanoparticle formulation of irinotecan encapsulated in liposomes. The aims of this study were to investigate the dose-limiting toxicity (DLT), maximum tolerated dose (MTD) and pharmacokinetics (PK) of PEP02 in combination with 5-FU and LV, in patients with advanced refractory solid tumors. METHODS: Patients were enrolled in cohorts to receive PEP02 from 60 to 120 mg/m2 (dose expressed as the irinotecan hydrochloride trihydrate salt) as a 90-min intravenous infusion on day 1, followed by 24 h infusion of 5-FU 2,000 mg/m2 and LV 200 mg/m2 on days 1 and 8, every 3 weeks. RESULTS: A total of 16 patients were assigned to four dose levels, 60 (three patients), 80 (six patients), 100 (five patients) and 120 mg/m2 (two patients). DLT was observed in four patients, two at the 100 mg/m2 dose level (one had grade III infection with hypotension and grade III hemorrhage; the other had grade III diarrhea and grade IV neutropenia), and two at the 120 mg/m2 dose level (one had grade III diarrhea and grade IV neutropenia; the other had grade III diarrhea). The MTD of PEP02 was determined as 80 mg/m2. The most common treatment-related adverse events were nausea (81%), diarrhea (75%) and vomiting (69%). Among the six patients who received the MTD, one patient exhibited partial response, four patients had stable disease and one showed progressive disease. Pharmacokinetic data showed that PEP02 had a lower peak plasma concentration, longer half-life, and increased area under the plasma concentration-time curve from zero to time t of SN-38 than irinotecan at similar dose level. CONCLUSIONS: The MTD of PEP02 on day 1 in combination with 24-h infusion of 5-FU and LV on days 1 and 8, every 3 weeks was 80 mg/m2, which will be the recommended dose for future studies. TRIAL REGISTRATION: The trial was retrospectively registered ( NCT02884128 ) with date of registration: August 12, 2016.

The impact of pain control on physical and psychiatric functions of cancer patients: a nation-wide survey in Taiwan.

OBJECTIVE: To investigate the prevalence of pain in cancer patients at different disease statuses, the impact of pain on physical and psychiatric functions of patients and the satisfaction of pain control of patients at outpatient clinic department in Taiwan. METHODS: Short form of the Brief Pain Inventory was used as the outcome questionnaire. Unselected patients of different cancers and different disease statuses at outpatient clinic department were included. The impacts of their current pain control on physical function, psychiatric function and the satisfaction of doctors were evaluated. Logistic regression analyses were performed to evaluate whether the interference scale performed identically in the different analgesic ladders. The dependent variables were satisfaction toward physician and treatment. RESULTS: A total of 14 sites enrolled 2075 patients in the study. One thousand and fifty-one patients reported pain within the last 1 week. In patients whose diseases deteriorated, >60% of them need analgesics for pain control. Pain influenced physical and psychiatric functions of patients, especially in the deteriorated status. More than 80% of patients were satisfied about current pain control, satisfaction rate related to disease status, pain intensities and treatments for pain. CONCLUSION: Our study found that different cancers at different statuses had pain at variable severity. Pain can influence physical and psychological functions significantly. More than 75% of subjects reported satisfaction over physician and pain management in outpatient clinic department patients with cancer pain in Taiwan.

Gemcitabine plus cisplatin for patients with recurrent or metastatic nasopharyngeal carcinoma in Taiwan: a multicenter prospective Phase II trial.

OBJECTIVE: This multicenter Phase II trial evaluated the toxicity/efficacy of gemcitabine plus cisplatin as first-line chemotherapy in patients with recurrent/metastatic nasopharyngeal carcinoma. METHODS: Gemcitabine 1250 mg/m(2) on Days 1 and 8 and cisplatin 75 mg/m(2) on Day 1 were administered at a 3-week interval. The primary endpoint was the response rate. Secondary endpoints included progression-free survival, overall survival, response duration and safety. RESULTS: Fifty-two patients were recruited between 2004 and 2008. The response rate was 51.9% (complete remission rate, 9.6%) in the intent-to-treat group. The median progression-free and overall survivals were 9.8 and 14.6 months, respectively. The major Grade III/IV adverse event was leucopenia (61.6%). The mean number of cycles was 6.63 ± 0.40. The regimen was well-tolerated, although one treatment-related death occurred after severe sepsis from aspiration pneumonia. CONCLUSIONS: Gemcitabine plus cisplatin is an effective, well-tolerated regimen as a first-line treatment for recurrent/metastatic nasopharyngeal carcinoma.

Antiemetic therapy in Asia Pacific countries for patients receiving moderately and highly emetogenic chemotherapy--a descriptive analysis of practice patterns, antiemetic quality of care, and use of antiemetic guidelines.

PURPOSE: This paper reports prescribing patterns for prophylaxis of chemotherapy-induced nausea and vomiting (CINV) after highly or moderately emetogenic chemotherapy (HEC or MEC) for cancer in six Asia Pacific countries. METHODS: In a prospective noninterventional study, 31 sites in Australia, China, India, Singapore, South Korea, and Taiwan recorded details of CINV prophylaxis for the acute phase (first 24 h) and delayed phase (days 2-5) after single-day HEC or MEC for adult patients. Additional information on CINV prophylactic medications was collected from 6-day patient diaries. Primary antiemetic therapies were defined as corticosteroids, the 5-hydroxytryptamine-3 receptor antagonists (5HT3-RAs), and neurokinin-1 receptor antagonists (NK1-RAs). RESULTS: Evaluable patients in cycle 1 numbered 648 (318 [49%] HEC and 330 [51%] MEC) of mean (SD) age of 56 (12) years, including 58% women. For the acute phase after HEC, overall (and country range), 96% (91-100%) of patients received a 5HT3-RA, 87% (70-100%) a corticosteroid, and 43% (0-91%) an NK1-RA. CINV prophylaxis for the HEC delayed phase was more variable: including 22% (7-65%) 5HT3-RA, 52% (12-93%) corticosteroid, and 46% (0-88%) NK1-RA. For the MEC acute phase, 97% (87-100%) of patients received 5HT3-RA and 86% (73-97%) a corticosteroid. For the MEC delayed phase, 201 patients (61%) received a primary antiemetic, including 5HT3-RA (41%), corticosteroid (37%), and/or NK1-RA (4%). CONCLUSIONS: The 5HT3-RAs were prescribed consistently in all countries, while prescribing of other antiemetic therapies was variable, and corticosteroids were under-prescribed for CINV prophylaxis, particularly in the delayed phase.

Rationale and design of the Pan Australasian chemotherapy-induced emesis burden of illness study.

BACKGROUND: Preventing and managing chemotherapy-induced nausea and vomiting (CINV) remain important goals. The objective of the Pan Australasian chemotherapy-induced emesis burden of illness (PrACTICE) study was to describe the incidence of CINV after highly or moderately emetogenic chemotherapy (HEC or MEC) for cancer in current clinical practice in Australia and five Asian countries (China, India, Singapore, South Korea, and Taiwan). STUDY DESIGN: This prospective, observational study of CINV was conducted at 31 sites in these six countries from August 2011 through September 2012 and enrolled male and female adult patients (≥18 years of age) naïve to HEC and MEC who were scheduled to receive at least two cycles of single-day chemotherapy. The primary effectiveness endpoint was complete response, defined as no vomiting or use of rescue therapy, during chemotherapy cycle 1 in the overall phase (0-120 h), acute phase (0-24 h), and delayed phase (>24-120 h). Study outcomes were analyzed descriptively. Primary outcomes, CINV incidence, and treatment patterns (chemotherapy, CINV prophylaxis, rescue medication prescription, and rescue medication use) were assessed by phase (overall, acute, delayed), by cycle (as appropriate), within and across countries, and by level of chemotherapy emetogenicity (HEC vs. MEC). The impact of CINV in cycle 1 on CINV in cycle 2 was analyzed for all patients with evaluable data for cycle 2. No site-specific analyses were performed. The remainder of this special series of papers reports on the results of this study.

Incidence and predictors of anticipatory nausea and vomiting in Asia Pacific clinical practice--a longitudinal analysis.

PURPOSE: Some patients experience nausea and/or vomiting (NV) before receipt of chemotherapy. Our objective was to evaluate the impact of prior chemotherapy-induced NV (CINV) on the incidence of anticipatory NV in later cycles. METHODS: This multicenter, prospective non-interventional study enrolled chemotherapy-naïve adults scheduled to receive highly or moderately emetogenic chemotherapy (HEC/MEC) for cancer in six Asia Pacific countries, excluding those with emesis within 24 h before cycle 1 chemotherapy. On day 1 before chemotherapy, patients answered four questions regarding emesis in the past 24 h, nausea, expectation of post-chemotherapy nausea, and anxiety in the past 24 h, the latter three scored from 0-10 (none-maximum). Multivariate logistic regression was used to assess the impact of prior CINV on anticipatory NV in cycles 2 and 3. RESULTS: Five hundred ninety-eight patients (59% female) were evaluable in cycle 2 (49% HEC, 51% MEC). The incidence of anticipatory emesis was low before cycles 2 and 3 (1.5-2.3%). The incidence of clinically significant anticipatory nausea (score of ≥3) was 4.8, 7.9, and 8.3% before cycles 1, 2, and 3, respectively, with adjusted odds ratio (OR), 3.95 (95% confidence interval (CI), 2.23-7.00; p < 0.001) for patients with clinically significant nausea in prior cycles, compared with none. The adjusted ORs for other anticipatory NV endpoints ranged from 4.54-4.74 for patients with prior CINV. The occurrence of clinically significant anxiety in the prior cycle also resulted in a significantly increased likelihood of anticipatory nausea. CONCLUSIONS: These findings highlight the importance of preventing CINV in cycle 1 to reduce anticipatory NV in subsequent cycles.

Baseline patient characteristics, incidence of CINV, and physician perception of CINV incidence following moderately and highly emetogenic chemotherapy in Asia Pacific countries.

PURPOSE: This paper describes the incidence of chemotherapy-induced nausea and vomiting (CINV) after highly or moderately emetogenic chemotherapy (HEC or MEC) for cancer in six Asia Pacific countries. METHODS: Sequential adult patients naïve to chemotherapy and scheduled to receive at least two cycles of single-day HEC or MEC were enrolled in this prospective observational study. Patients completed the Multinational Association of Supportive Care in Cancer (MASCC) Antiemesis Tool on post-chemotherapy days 2 and 6 to record acute-phase (first 24 h) and delayed-phase (days 2-5) CINV. RESULTS: There were 648 evaluable patients (318 HEC, 330 MEC) from Australia (n = 74), China (153), India (88), Singapore (57), South Korea (151), and Taiwan (125). Mean (SD) patient age was 56 (12) and 58% of patients were women; the most common primary cancers were breast (27%), lung (22%), and colon (20%). Overall in cycle 1, complete response (no emesis or rescue antiemetics) was recorded by 69% (95% confidence interval (CI), 66-73) of all evaluable patients, with country percentages ranging from 55 to 78% (p < 0.001). After HEC, no emesis was recorded by 75% and no nausea by 38% of patients. After MEC, 80% had no emesis and 50% no nausea. Acute-phase CINV was better controlled than delayed-phase CINV, and the control of nausea was the lowest of any CINV measure in all phases. In a CINV perception survey, physicians tended to overestimate emesis rate and underestimate nausea rate. CONCLUSIONS: CINV remains a substantial problem, and country-specific information about CINV can be useful in developing strategies to improve outcomes for patients undergoing chemotherapy.

Lapatinib with trastuzumab for HER2-positive early breast cancer (NeoALTTO): survival outcomes of a randomised, open-label, multicentre, phase 3 trial and their association with pathological complete response.

BACKGROUND: Findings from the randomised phase 3 NeoALTTO trial in women with HER2-positive early breast cancer showed that the combination of lapatinib and trastuzumab significantly improved rates of pathological complete response compared with either drug alone. Here, we report data for the prespecified secondary endpoints of event-free and overall survival, and assess the association between these outcomes and pathological complete response. METHODS: We enrolled women with HER2-positive early breast cancer and randomly assigned them to receive oral lapatinib (1500 mg), intravenous trastuzumab (4 mg/kg loading dose followed by 2 mg/kg), or lapatinib (1000 mg) plus trastuzumab (same dose as for single agent) in combination for 6 weeks, followed by an additional 12 weeks of the assigned anti-HER2 therapy in combination with weekly paclitaxel (80 mg/m(2)). Definitive surgery was done 4 weeks after the last dose of paclitaxel. After surgery, women received three cycles of FEC (fluorouracil 500 mg/m(2) plus epirubicin 100 mg/m(2) plus cyclophosphamide 500 mg/m(2)) given intravenously every 3 weeks, followed by 34 weeks of the same assigned neoadjuvant anti-HER2 therapy. The primary endpoint was pathological complete response. Secondary endpoints included event-free and overall survival (intention-to-treat analysis), and the association between pathological complete response and event-free or overall survival (analysed by landmark analysis at 30 weeks after randomisation). Follow-up is ongoing, and the trial is registered with ClinicalTrials.gov, number NCT00553358. FINDINGS: 455 patients were enrolled: 154 (34%) were assigned to the lapatinib group, 149 (33%) to the trastuzumab group, and 152 (33%) to the lapatinib plus trastuzumab group. At an event follow-up of 3·77 years (IQR 3·50-4·22), 3-year event-free survival was 78% (95% CI 70-84) in the lapatinib group, 76% (68-82) in the trastuzumab group, and 84% (77-89) in the combination group. Event-free survival did not differ between the lapatinib and trastuzumab groups (HR 1·06, 95% CI 0·66-1·69, p=0·81), nor between the combination and trastuzumab groups (0·78, 0·47-1·28, p=0·33). Median survival follow-up was 3·84 years (IQR 3·60-4·24), and 3-year overall survival was 93% (95% CI 87-96) for lapatinib, 90% (84-94) for trastuzumab, and 95% (90-98) for combination therapy. Overall survival did not significantly differ between the lapatinib and trastuzumab groups (HR 0·86, 95% CI 0·45-1·63, p=0·65), nor between the combination and trastuzumab groups (0·62, 0·30-1·25, p=0·19). Landmark analyses showed that 3-year event-free survival was significantly improved for women who achieved pathological complete response compared with those who did not (HR 0·38, 95% CI 0·22-0·63, p=0·0003), as was 3-year overall survival (0·35, 0·15-0·70, p=0·005). Adverse events occurred in 149 (99%) patients receiving lapatinib, 142 (96%) patients receiving trastuzumab, and 147 (99%) patients receiving combination therapy. The most common adverse events were diarrhoea, rash or erythema, hepatic adverse events, and neutropenia (not related to FEC administration), and were consistent with known safety profiles of lapatinib and trastuzumab. Three primary and eight secondary cardiac events occurred, with no significant difference in incidence between treatment groups for primary or any cardiac events. INTERPRETATION: Although event-free survival or overall survival did not differ between treatment groups, findings from our study confirm that patients who achieve pathological complete response after neoadjuvant anti-HER2 therapy have longer event-free and overall survival than do patients without pathological complete response.

Siltuximab for multicentric Castleman's disease: a randomised, double-blind, placebo-controlled trial.

BACKGROUND: Multicentric Castleman's disease is a rare lymphoproliferative disorder driven by dysregulated production of interleukin 6. No randomised trials have been done to establish the best treatment for the disease. We assessed the safety and efficacy of siltuximab-a chimeric monoclonal antibody against interleukin 6-in HIV-negative patients with multicentric Castleman's disease. METHODS: We did this randomised, double-blind, placebo-controlled study at 38 hospitals in 19 countries worldwide. We enrolled HIV-negative and human herpesvirus-8-seronegative patients with symptomatic multicentric Castleman's disease. Treatment allocation was randomised with a computer-generated list, with block size six, and stratification by baseline corticosteroid use. Patients and investigators were masked to treatment allocation. Patients were randomly assigned (2:1) to siltuximab (11 mg/kg intravenous infusion every 3 weeks) or placebo; all patients also received best supportive care. Patients continued treatment until treatment failure. The primary endpoint was durable tumour and symptomatic response for at least 18 weeks for the intention-to-treat population. Enrolment has been completed. The study is registered with ClinicalTrials.gov, number NCT01024036. FINDINGS: We screened 140 patients, 79 of whom were randomly assigned to siltuximab (n=53) or placebo (n=26). Durable tumour and symptomatic responses occurred in 18 (34%) of 53 patients in the siltuximab group and none of 26 in the placebo group (difference 34·0%, 95% CI 11·1-54·8, p=0·0012). The incidence of grade 3 or more adverse events (25 [47%] vs 14 [54%]) and serious adverse events (12 [23%] vs five [19%]) was similar in each group despite longer median treatment duration with siltuximab than with placebo (375 days [range 1-1031] vs 152 days [23-666]). The most common grade 3 or higher were fatigue (five vs one), night sweats (four vs one), and anaemia (one vs three). Three (6%) of 53 patients had serious adverse events judged reasonably related to siltuximab (lower respiratory tract infection, anaphylactic reaction, sepsis). INTERPRETATION: Siltuximab plus best supportive care was superior to best supportive care alone for patients with symptomatic multicentric Castleman's disease and well tolerated with prolonged exposure. Siltuximab is an important new treatment option for this disease. FUNDING: Janssen Research & Development.

Associations between accurate prognostic understanding and end-of-life care preferences and its correlates among Taiwanese terminally ill cancer patients surveyed in 2011-2012.

OBJECTIVE: Adequate knowledge of prognosis is a prerequisite for planning appropriate end-of-life (EOL) care. However, questions remain about whether the association between prognostic understanding and EOL-care intensity reflects terminally ill cancer patients' preferences for EOL care. This study investigated the associations between accurate prognostic understanding and EOL-care preferences, and identified correlates of accurate prognostic understanding. METHODS: A cross-sectional survey of 2452 terminally ill cancer patients from 23 hospitals throughout Taiwan. RESULTS: Nearly half the participants (49.80%) accurately understood their prognosis. These patients were significantly more likely to prefer comfort-oriented care as their goal for EOL care, but less likely to prefer life-prolonging treatments. Accurately understanding prognosis decreased the likelihood of preferring intensive care unit care, cardiac pulmonary resuscitation, cardiac massage, intubation, and mechanical ventilation support, but increased preference for hospice care. Participants were significantly more likely to accurately understand their prognosis if they were male, younger, better educated, with a stronger preference for physicians to disclose their prognosis to them, and receiving care at a hospital accredited as a medical center and in northwest Taiwan. The likelihood of accurate prognostic understanding was lower for patients recently (≤ 12 months) diagnosed with cancers with better prognosis and hematologic malignancies than for lung cancer patients. CONCLUSIONS: Accurately understanding prognosis is associated with fewer preferences for life-sustaining treatments and is correlated with both patient and institutional characteristics. Interventions should be developed to improve accurate prognostic understanding, thus facilitating informed EOL-care decisions that may limit the use of aggressive interventions.

A correlational study of suicidal ideation with psychological distress, depression, and demoralization in patients with cancer.

PURPOSE: This study aims to study the effects of depression and demoralization on suicidal ideation and to determine the feasibility of the Distress Thermometer as a screening tool for patients with cancer who experience depression and demoralization, and thus to establish a model screening process for suicide prevention. METHODS: Purposive sampling was used to invite inpatients and outpatients with lung cancer, leukemia, and lymphoma. Two hundred participants completed the questionnaire, which included the Distress Thermometer (DT), Patient Health Questionnaire-9 (PHQ-9), Demoralization Scale-Mandarin Version (DS-MV), and Beck Scale for Suicide Ideation. All data obtained were analyzed using SPSS 18.0 and SAS 9.3. RESULTS: Tobit regression analysis showed that demoralization influenced suicidal ideation more than depression did (t = 2.84, p < 0.01). When PHQ-9 ≥ 10 and DS-MV ≥42 were used as criteria for the DT, receiver operating characteristic analysis revealed that the AUC values were 0.77-0.79, with optimal cutoff points for both of DT ≥5; sensitivity 76.9 and 80.6 %, respectively; and specificity of 73.9 and 72.2 %, respectively. CONCLUSIONS: Demoralization had more influence on suicidal ideation than depression did. Therefore, attention should be paid to highly demoralized patients with cancer or high demoralization comorbid with depression for the purposes of suicide evaluation and prevention. The DT scale (with a cutoff of ≥5 points) has discriminative ability as a screening tool for demoralization or depression and can also be used in clinical settings for the preliminary screening of patients with cancer and high suicide risk.

Physician-patient end-of-life care discussions: correlates and associations with end-of-life care preferences of cancer patients-a cross-sectional survey study.

BACKGROUND: Honoring patients' treatment preferences is a key component of high-quality end-of-life care. Connecting clinical practices to patients' preferences requires effective communication. However, few cancer patients reported discussing end-of-life-care preferences with their physicians. AIM: To identify correlates of physician-patient end-of-life-care discussions and to investigate associations of physician-patient end-of-life-care discussions with patient end-of-life-care preferences. DESIGN: A cross-sectional survey from April 2011 through November 2012. SETTING/PARTICIPANTS: A convenience sample of 2467 cancer patients (89.3% participation rate) whose disease was diagnosed as terminal and unresponsive to current curative cancer treatment was recruited from 23 teaching hospitals throughout Taiwan. RESULTS: Only 7.8% of respondents reported discussing end-of-life-care preferences with their physicians. Physicians were more likely to discuss end-of-life-care preferences with cancer patients who accurately understood their prognosis but less likely to do so if patients were married or received care in a hospital with an inpatient hospice unit. Furthermore, physician-patient end-of-life-care discussions were significantly, positively associated with the likelihood of preferring comfort-oriented care and hospice care, but negatively associated with preferences for receiving cardiopulmonary resuscitation when life is in danger and aggressive life-sustaining treatments at end of life, including intensive care unit admission, cardiac massage, intubation, and mechanical ventilation support. CONCLUSION: Physician-patient end-of-life-care discussions are correlated with accurate prognostic awareness, marital status, and institutional characteristics and negatively associated with terminally ill cancer patients' preferences for aggressive end-of-life care. Interventions should be developed to facilitate timely end-of-life-care discussions between at-risk patients and their physicians, thus honoring patients' end-of-life-care preferences and possibly avoiding futile life-sustaining treatments.

Carbohydrate Antigen 19-9 Response to Initial Adjuvant Chemotherapy Predicts Survival and Failure Pattern of Resected Pancreatic Adenocarcinoma but Not Which Patients Are Suited for Additional Adjuvant Chemoradiation Therapy: From a Prospective Randomized Study.

PURPOSE: The predictive value of carbohydrate antigen 19-9 (CA19-9) for adjuvant chemo(radiation) therapy of resected pancreatic adenocarcinoma (PDAC) is undefined. METHODS AND MATERIALS: We analyzed CA19-9 levels in patients with resected PDAC in a prospective randomized trial of adjuvant chemotherapy with or without additional chemoradiation therapy (CRT). Patients with postoperative CA19-9 ≤92.5 U/mL and serum bilirubin ≤2 mg/dL were randomized to 2 arms: patients in 1 arm received 6 cycles of gemcitabine, whereas those in the other received 3 cycles of gemcitabine followed by CRT and another 3 cycles of gemcitabine. Serum CA19-9 was measured every 12 weeks. Those who had CA19-9 levels always <3 U/mL were excluded from the exploratory analysis. RESULTS: One hundred forty-seven patients were enrolled in this randomized trial. Twenty-two patients with CA19-9 levels always ≤3 U/mL were excluded from the analysis. For the 125 participants, median overall survival (OS) and recurrence-free survival were 23.1 and 12.1 months, respectively, with no significant differences between the study arms. Postresection CA19-9 levels and, to a lesser extent, CA19-9 change predicted OS (P = .040 and .077, respectively). For the 89 patients who completed the initial 3 cycles of adjuvant gemcitabine, the CA19-9 response was significantly correlated with initial failure over the distant site (P = .023) and OS (P = .0022). Despite a trend of less initial failure over the locoregional area (P = .031), neither postoperative CA19-9 level nor CA19-9 response helped to select patients who might have a survival benefit from additional adjuvant CRT. CONCLUSIONS: CA19-9 response to initial adjuvant gemcitabine predicts survival and distant failure of PDAC after resection; however, it cannot select patients suited for additional adjuvant CRT. Monitoring CA19-9 levels during adjuvant therapy for postoperative patients with PDAC may guide therapeutic decisions to prevent distant failure.

Vandetanib in patients with inoperable hepatocellular carcinoma: a phase II, randomized, double-blind, placebo-controlled study.

BACKGROUND & AIMS: Inhibitors of vascular endothelial growth factor receptor (VEGFR) and epidermal growth factor receptor (EGFR) have shown anti-tumor activities in advanced hepatocellular carcinoma (HCC). The present study evaluated the efficacy and safety of vandetanib, an oral inhibitor of both VEGFR and EGFR, in patients with unresectable advanced HCC. METHODS: Eligible patients were randomized 1:1:1 to receive vandetanib 300mg/day, vandetanib 100mg/day, or placebo. Upon disease progression, all patients had the option to receive open-label vandetanib 300mg/day. The primary objective was to evaluate tumor stabilization rate (complete response+partial response+stable disease ⩾4months). Secondary assessments included progression-free survival (PFS), overall survival (OS) and safety. Biomarker studies included circulating pro-angiogenic factors and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). RESULTS: Sixty-seven patients were randomized to vandetanib 300mg (n=19), vandetanib 100mg (n=25) or placebo (n=23) groups. Twenty-nine patients entered open-label treatment. Vandetanib induced a significant increase in circulating VEGF and decrease in circulating VEGFR levels. In both vandetanib arms, tumor stabilization rate was not significantly different from placebo: 5.3% (vandetanib 300mg), 16.0% (vandetanib 100mg) and 8.7% (placebo). DCE-MRI did not detect significant vascular change after vandetanib treatment. Although trends of improved PFS and OS after vandetanib treatment were found, they were statistically insignificant. The most common adverse events were diarrhea and rash, whose incidence did not differ significantly between treatment groups. CONCLUSIONS: Vandetanib has limited clinical activity in HCC. The safety profile was consistent with previous studies.
