RESUMO

BACKGROUND: Patients with advanced cancer who no longer have standard treatment options available may decide to participate in early phase clinical trials (i.e. experimental treatments with uncertain outcomes). Shared decision-making (SDM) models help to understand considerations that influence patients' decision. Discussion of patient values is essential to SDM, but such communication is often limited in this context and may require new interventions. The OnVaCT intervention, consisting of a preparatory online value clarification tool (OnVaCT) for patients and communication training for oncologists, was previously developed to support SDM. This study aimed to qualitatively explore associations between patient values that are discussed between patients and oncologists during consultations about potential participation in early phase clinical trials before and after implementation of the OnVaCT intervention. METHODS: This study is part of a prospective multicentre nonrandomized controlled clinical trial and had a between-subjects design: pre-intervention patients received usual care, while post-intervention patients additionally received the OnVaCT. Oncologists participated in the communication training between study phases. Patients' initial consultation on potential early phase clinical trial participation was recorded and transcribed verbatim. Applying a directed approach, two independent coders analysed the transcripts using an initial codebook based on previous studies. Steps of continuous evaluation and revision were repeated until data saturation was reached. RESULTS: Data saturation was reached after 32 patient-oncologist consultations (i.e. 17 pre-intervention and 15 post-intervention). The analysis revealed the values: hope, perseverance, quality or quantity of life, risk tolerance, trust in the healthcare system/professionals, autonomy, social adherence, altruism, corporeality, acceptance of one's fate, and humanity. Patients in the pre-intervention phase tended to express values briefly and spontaneously. Oncologists acknowledged the importance of patients' values, but generally only gave 'contrasting' examples of why some accept and others refuse to participate in trials. In the post-intervention phase, many oncologists referred to the OnVaCT and/or asked follow-up questions, while patients used longer phrases that combined multiple values, sometimes clearly indicating their weighing. CONCLUSIONS: While all values were recognized in both study phases, our results have highlighted the different communication patterns around patient values in SDM for potential early phase clinical trial participation before and after implementation of the OnVaCT intervention. This study therefore provides a first (qualitative) indication that the OnVaCT intervention may support patients and oncologists in discussing their values.

RESUMO

PURPOSE: Adequate integration of palliative care in oncological care can improve the quality of life in patients with advanced cancer. Whether such integration affects the use of diagnostic procedures and medical interventions has not been studied extensively. We investigated the effect of the implementation of a standardized palliative care pathway in a hospital on the use of diagnostic procedures, anticancer treatment, and other medical interventions in patients with incurable cancer at the end of their life. METHODS: In a pre- and post-intervention study, data were collected concerning adult patients with cancer who died between February 2014 and February 2015 (pre-PCP period) or between November 2015 and November 2016 (post-PCP period). We collected information on diagnostic procedures, anticancer treatments, and other medical interventions during the last 3 months of life. RESULTS: We included 424 patients in the pre-PCP period and 426 in the post-PCP period. No differences in percentage of laboratory tests (85% vs 85%, p = 0.795) and radiological procedures (85% vs 82%, p = 0.246) were found between both groups. The percentage of patients who received anticancer treatment or other medical interventions was lower in the post-PCP period (40% vs 22%, p < 0.001; and 42% vs 29%, p < 0.001, respectively). CONCLUSIONS: Implementation of a PCP resulted in fewer medical interventions, including anticancer treatments, in the last 3 months of life. Implementation of the PCP may have created awareness among physicians of patients' impending death, thereby supporting caregivers and patients to make appropriate decisions about medical treatment at the end of life.

RESUMO

OBJECTIVE: This article identifies the core values that play a role in patients' decision-making process about participation in early-phase clinical cancer trials. METHODS: Face-to-face, semi-structured serial interviews (n = 22) were performed with thirteen patients with advanced cancer recruited in two Dutch specialized cancer centers. In a cyclic qualitative analysis process, open and axial coding of the interviews finally led to an overview of the values that are woven into patients' common language about cancer and clinical trials. RESULTS: Six core values were described, namely, acceptance creates room for reconsideration of values, reconciliation with one's fate, hope, autonomy, body preservation, and altruism. Previously found values in advanced cancer, such as acceptance, hope, autonomy, and altruism, were further qualified. Reconciliation with one's fate and body preservation were highlighted as new insights for early-phase clinical cancer trial literature. CONCLUSIONS: This article furthers the understanding of core values that play a role in the lives and decision-making of patients with advanced cancer who explore participation in early-phase clinical cancer trials. These values do not necessarily have to be compatible with one another, making tragic choices necessary. Understanding the role of core values can contribute to professional sensitivity regarding what motivates patients' emotions, thoughts, and decisions and help patients reflect on and give words to their values and preferences. It supports mutual understanding and dialog from which patients can make decisions according to their perspectives on a good life for themselves and their fellows in the context of participation in an early-phase clinical cancer trial.

RESUMO

BACKGROUND: Better insight in patients' prognosis can help physicians to timely initiate advance care planning (ACP) discussions with patients with chronic obstructive pulmonary disease (COPD). We aimed to identify predictors of mortality. METHODS: We systematically searched databases Embase, PubMed, MEDLINE, Web of Science, and Cochrane Central in April 2020. Papers reporting on predictors or prognostic models for mortality at 3 months and up to 24 months were assessed on risk-of-bias. We performed a meta-analysis with a fixed or random-effects model, and evaluated the discriminative ability of multivariable prognostic models. RESULTS: We included 42 studies (49-418,251 patients); 18 studies were included in the meta-analysis. Significant predictors of mortality within 3-24 months in the random-effects model were: previous hospitalization for acute exacerbation (hazard ratio [HR] 1.97; 95% confidence interval [CI] 1.32-2.95), hospital readmission within 30 days (HR 5.01; 95% CI 2.16-11.63), cardiovascular comorbidity (HR 1.89; 95% CI 1.25-2.87), age (HR 1.48; 95% CI 1.38-1.59), male sex (HR 1.68; 95% CI 1.38-1.59), and long-term oxygen therapy (HR 1.74; 95% CI 1.10-2.73). Nineteen previously developed multicomponent prognostic models, as examined in 11 studies, mostly had moderate discriminate ability. CONCLUSION: Identified predictors of mortality may aid physicians in selecting COPD patients who may benefit from ACP. However, better discriminative ability of prognostic models or development of a new prognostic model is needed for further large-scale implementation.

RESUMO

OBJECTIVE: The aim of this study is to examine why patients are hospitalised in the last stage of life. METHODS: Our study was conducted in a large Dutch teaching hospital. We conducted a retrospective chart review of patients aged ≥18 years who died of cancer either during hospitalisation or after discharge to receive terminal care outside the hospital. We collected data about the characteristics of these hospitalisations and indicators of advance care planning. RESULTS: Of the 264 deceased patients, 56% had died in the hospital and 44% after hospital discharge. Of all patients, 80% had been admitted to the hospital because of symptom distress. Dyspnoea (39%) and pain (33%) were the most common symptoms. Most patients underwent diagnostic procedures (laboratory tests [97%] and radiology tests [91%]) and received medical treatment (analgesics [71%] and antibiotics [55%]) during their hospitalisation. A 'Do-Not-Resuscitate' code had been recorded before admission in 42% of the patients and in an additional 52% during admission. CONCLUSION: Our study shows that patients with cancer in the last stage of life were mainly admitted to the hospital because of symptom distress. Some hospitalisations and in-hospitals deaths may be avoided by more timely recognition of patients' impending death and start of advance care planning.

RESUMO

BACKGROUND: Individuals' willingness to engage in advance care planning is influenced by factors such as culture and religious beliefs. While most studies on advance care planning in Asia have been performed in high-income countries, Indonesia is a lower-middle-income country, with a majority of strongly collectivist and religiously devout inhabitants. We studied the perspectives of Indonesian patients with cancer and family caregivers regarding advance care planning by first exploring their experiences with medical information-disclosure, decision-making, and advance care planning and how these experiences influence their perspectives on advance care planning. METHODS: We conducted semi-structured interviews among 16 patients with cancer and 15 family caregivers in a national cancer center in Jakarta and a tertiary academic general hospital in Yogyakarta. We performed an inductive thematic analysis using open, axial, and selective coding. The rigor of the study was enhanced by reflective journaling, dual coding, and investigator triangulation. RESULTS: Twenty-six of 31 participants were younger than 60 years old, 20 were Muslim and Javanese, and 17 were college or university graduates. Four major themes emerged as important in advance care planning: (1) participants' perceptions on the importance or harmfulness of cancer-related information, (2) the importance of communicating bad news sensitively (through empathetic, implicit, and mediated communication), (3) participants' motives for participating in medical decision-making (decision-making seen as patients' right or responsibility, or patients' state of dependency on others), and (4) the complexities of future planning (e.g., due to its irrelevance to participants' religious beliefs and/or their difficulties in seeing the relevance of future planning). CONCLUSIONS: Culturally sensitive approaches to advance care planning in Indonesia should address the importance of facilitating open communication between patients and their families, and the various perspectives on information provision, bad news communication, and decision-making. Advance care planning should focus on the exploration of patients' values, rather than drafting treatment plans in advance.

RESUMO

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a progressive fatal disease with a heterogeneous disease course. Timely initiation of palliative care is often lacking. The surprise question "Would you be surprised if this patient died within the next year?" is increasingly used as a clinical prognostic tool in chronic diseases but has never been evaluated in IPF. OBJECTIVE: We aimed to evaluate the predictive value of the surprise question for 1-year mortality in IPF. METHODS: In this prospective cohort study, clinicians answered the surprise question for each included patient. Clinical parameters and mortality data were collected. The sensitivity, specificity, accuracy, negative, and positive predictive value of the surprise question with regard to 1-year mortality were calculated. Multivariable logistic regression analysis was performed to evaluate which factors were associated with mortality. In addition, discriminative performance of the surprise question was assessed using the C-statistic. RESULTS: In total, 140 patients were included. One-year all-cause mortality was 20% (n = 28). Clinicians identified patients with a survival of <1 year with a sensitivity of 68%, a specificity of 82%, an accuracy of 79%, a positive predictive value of 49%, and a negative predictive value of 91%. The surprise question significantly predicted 1-year mortality in a multivariable model (OR 3.69; 95% CI 1.24-11.02; p = 0.019). The C-statistic of the surprise question to predict mortality was 0.75 (95% CI 0.66-0.85). CONCLUSIONS: The answer on the surprise question can accurately predict 1-year mortality in IPF. Hence, this simple tool may enable timely focus on palliative care for patients with IPF.

RESUMO

Importance: Death rattle, defined as noisy breathing caused by the presence of mucus in the respiratory tract, is relatively common among dying patients. Although clinical guidelines recommend anticholinergic drugs to reduce the death rattle after nonpharmacological measures fail, evidence regarding their efficacy is lacking. Given that anticholinergics only decrease mucus production, it is unknown whether prophylactic application may be more appropriate. Objective: To determine whether administration of prophylactic scopolamine butylbromide reduces the death rattle. Design, Setting, and Participants: A multicenter, randomized, double-blind, placebo-controlled trial was performed in 6 hospices in the Netherlands. Patients with a life expectancy of 3 or more days who were admitted to the participating hospices were asked to give advance informed consent from April 10, 2017, through December 31, 2019. When the dying phase was recognized, patients fulfilling the eligibility criteria were randomized. Of the 229 patients who provided advance informed consent, 162 were ultimately randomized. The date of final follow-up was January 31, 2020. Interventions: Administration of subcutaneous scopolamine butylbromide, 20 mg four times a day (n = 79), or placebo (n = 78). Main Outcomes and Measures: The primary outcome was the occurrence of a grade 2 or higher death rattle as defined by Back (range, 0-3; 0, no rattle; 3, rattle audible standing in the door opening) measured at 2 consecutive time points with a 4-hour interval. Secondary outcomes included the time between recognizing the dying phase and the onset of a death rattle and anticholinergic adverse events. Results: Among 162 patients who were randomized, 157 patients (97%; median age, 76 years [IQR, 66-84 years]; 56% women) were included in the primary analyses. A death rattle occurred in 10 patients (13%) in the scopolamine group compared with 21 patients (27%) in the placebo group (difference, 14%; 95% CI, 2%-27%, P = .02). Regarding secondary outcomes, an analysis of the time to death rattle yielded a subdistribution hazard ratio (HR) of 0.44 (95% CI, 0.20-0.92; P = .03; cumulative incidence at 48 hours: 8% in the scopolamine group vs 17% in the placebo group). In the scopolamine vs placebo groups, restlessness occurred in 22 of 79 patients (28%) vs 18 of 78 (23%), dry mouth in 8 of 79 (10%) vs 12 of 78 (15%), and urinary retention in 6 of 26 (23%) vs 3 of 18 (17%), respectively. Conclusions and Relevance: Among patients near the end of life, prophylactic subcutaneous scopolamine butylbromide, compared with placebo, significantly reduced the occurrence of the death rattle.

RESUMO

BACKGROUND: Patients with advanced cancer for whom standard systemic treatment is no longer available may be offered participation in early phase clinical trials. In the decision making process, both medical-technical information and patient values and preferences are important. Since patients report decisional conflict after deciding on participation in these trials, improving the decision making process is essential. We aim to develop and evaluate an Online Value Clarification Tool (OnVaCT) to assist patients in clarifying their values around this end-of-life decision. This improved sharing of values is hypothesized to support medical oncologists in tailoring their information to individual patients' needs and, consequently, to support patients in taking decisions in line with their values and reduce decisional conflict. METHODS: In the first part, patients' values and preferences and medical oncologists' views hereupon will be explored in interviews and focus groups to build a first prototype OnVaCT using digital communication (serious gaming). Next, we will test feasibility during think aloud sessions, to deliver a ready-to-implement OnVaCT. In the second part, the OnVaCT, with accompanied training module, will be evaluated in a pre-test (12-18 months before implementation) post-test (12-18 months after implementation) study in three major Dutch cancer centres. We will include 276 patients (> 18 years) with advanced cancer for whom standard systemic therapy is no longer available, and who are referred for participation in early phase clinical trials. The first consultation will be recorded to analyse patient-physician communication regarding the discussion of patients' values and the decision making process. Three weeks afterwards, decisional conflict will be measured. DISCUSSION: This project aims to support the discussion of patient values when considering participation in early phase clinical trials. By including patients before their first appointment with the medical oncologist and recording that consultation, we are able to link decisional conflict to the decision making process, e.g. the communication during consultation. The study faces challenges such as timely including patients within the short period between referral and first consultation. Furthermore, with new treatments being developed rapidly, molecular stratification may affect the patient populations included in the pre-test and post-test periods. TRIAL REGISTRATION: Netherlands Trial Registry number: NTR7551 (prospective; July 17, 2018).

RESUMO

BACKGROUND: In the outpatient setting, pain management is often inadequate in patients with cancer-related pain, because of patient- and professional-related barriers in communication and infrequent contacts. The internet may provide new opportunities for monitoring these patients. PURPOSE: The purpose of this study was to investigate whether internet monitoring of cancer-related pain in outpatients was feasible. METHODS: We developed an internet application that contained a pain diary, eConsult, and patient pain education. In the pain diary, patients scored their pain intensity (0-10 Numeric Rating Scale) and analgesic use daily and their side effects twice a week. Feasibility was defined as the percentage of diaries patients completed during the first 6 weeks. RESULTS: We included 100 outpatients. Sixteen were not evaluable due to cognitive problems (2); withdrawal of participation (2); internet problems (2), or because they were too ill (10). During the first 6 weeks, 60% of 84 evaluable patients completed their diary for at least 65% of the days (median number of diaries, 21; range, 3-42) and asked for a median of five eConsults (range, 0-37). Patients most frequently used an eConsult for questions about pain or side effects, how to use their analgesics and to improve their self-management. Over the 6-week period, current pain intensity decreased from 3.3 (SD = 2) to 2.5 (SD = 1.6, p = 0.005), and worst pain intensity decreased from 5.7 (SD = 2) to 3.8 (SD = 2.0, p < 0.001). CONCLUSION: Internet monitoring of pain is feasible in most outpatients with cancer-related pain. The frequent use of the pain diary in the majority of patients indicates that those patients felt confident with the regular assessment of pain.

RESUMO

BACKGROUND: Death rattle (DR), caused by mucus in the respiratory tract, occurs in about half of patients who are in the dying phase. Relatives often experience DR as distressing. Anticholinergics are recommended to treat DR, although there is no evidence for the effect of these drugs. Anticholinergic drugs decrease the production of mucus but do not affect existing mucus. We therefore hypothesize that these drugs are more effective when given prophylactically. METHODS: We set up a randomized double-blind, placebo-controlled, multi-center study evaluating the efficacy of prophylactically given subcutaneous scopolaminebutyl for the prevention of DR in the dying phase. The primary outcome is the occurrence of DR defined as grade ≥ 2 according to the scale of Back measured by a nurse at 2 consecutive time points with an interval of 4 h. Secondary outcomes include adverse effects, quality of dying, quality of life in the last three days and bereavement. A sub-study will explore the experience of participating in a clinical trial in the dying phase from the perspective of relatives. Four hospices will include 200 patients. DISCUSSION: This is the first double-blind placebo-controlled study to prevent DR in patients in the hospice setting. Research in dying patients is challenging. We will apply ethical and organizational strategies as suggested in the literature. TRIAL REGISTRATION: The trial is retrospectively registered in the Dutch Trial register, identifier NTR 6438 June 2017. EudractCT number 2016-002287-14.

RESUMO

OBJECTIVE: The primary outcome of the current study is, whether there is a protective effect of prior chemotherapy or of prior granulocyte colony-stimulating factor (G-CSF) on the next cycle blood cell counts. METHODS: Hematologic toxicity was evaluated, based on a randomized phase III study in breast cancer patients (n = 167) with >20% risk of febrile neutropenia. The primary endpoint was the nadir blood cell counts for patients treated with G-CSF given during all 6 chemotherapy cycles or limited to the first 2 chemotherapy cycles only. RESULTS: For the present analyses, 47 patients were eligible. In the G-CSF 1-6 arm, the median white blood cell count (WBC) and absolute neutrophil count (ANC) nadir slowly decreased from 10.8 × 109/L in cycle 1 to 7.5 × 109/L in cycle 6 and from 7.1 × 109/L to 5.5 × 109/L, respectively. The median WBC nadir in the G-CSF 1-2 arm decreased from 1.2 × 109/L in cycle 3 to 0.9 × 109/L in cycle 6 and the ANC nadir showed a grade 4 neutropenia of 0.1 × 109/L in cycles 3-6. All patients had ANC recovery to normal levels (≥1.5 × 109/L) without delay on day 1 of the next cycle. CONCLUSION: We conclude that there is no protective effect of prior G-CSF or prior chemotherapy use on nadir blood cell counts in subsequent cycles.

RESUMO

Fentanyl is a strong opioid that is available for various administration routes, and which is widely used to treat cancer-related pain. Many factors influence the fentanyl pharmacokinetics leading to a wide inter- and intrapatient variability. This systematic review summarizes multiple studied factors that potentially influence fentanyl pharmacokinetics with a focus on implications for cancer patients. The use of CYP3A4 inhibitors and inducers, impaired liver function, and heating of the patch potentially influence fentanyl pharmacokinetics in a clinically relevant way. In elderly patients, current data suggest that we should carefully dose fentanyl due to alterations in absorption and metabolism. The influence of BMI and gender on fentanyl pharmacokinetics is questionable, most probably due to a large heterogeneity in the published studies. Pharmacogenetics, e.g. the CYP3A5*3 gene polymorphism, may influence fentanyl pharmacokinetics as well, although further study is warranted. Several other factors have been studied but did not show significant and clinically relevant effects on fentanyl pharmacokinetics. Unfortunately, most of the published papers that studied factors influencing fentanyl pharmacokinetics describe healthy volunteers instead of cancer patients. Results from the studies in volunteers may not be simply extrapolated to cancer patients because of multiple confounding factors. To handle fentanyl treatment in a population of cancer patients, it is essential that physicians recognize factors that influence fentanyl pharmacokinetics, thereby preventing potential side-effects and increasing its efficacy.

RESUMO

BACKGROUND: Inadequate adherence to prescribed analgesics may be one of the reasons why patients with cancer experience unrelieved pain. Adherence is directly influenced by patients' barriers about pain management. Patient pain education programs (PEPs) have been developed to reduce patients' barriers and increase patients' adherence to their analgesics. The purpose of this article was to evaluate patients' adherence in patients receiving a pain consult and patient pain education in comparison with patients receiving standard pain treatment (standard care [SC]), to better explore the difficulties in medication adherence in cancer-related pain and the effects of PEP. METHODS: In 54 adult outpatients with cancer-related pain, patients' adherence to the prescribed around-the-clock analgesics was measured with a Medication Event Monitoring System, in the following time intervals: weeks 1 and 2, weeks 3 and 4, and weeks 7 and 8 after randomization. Adherence was differentiated into taking adherence, taking the correct dose, and taking analgesics at the right time intervals. RESULTS: Taking adherence increased in the intervention group compared to baseline (from 91% to 93%) and decreased in the SC group (from 85% to 78%; P < 0.05). At the end of the study, more patients in the intervention group took their analgesics at the right intervals (78%) than did patients in the SC group (64%, P < 0.05). During the study, patients were more adherent to opioids than to World Health Organization step 1 analgesics. CONCLUSION: The combined intervention can increase adherence. The true problem in pain management is that patients do not take their prescribed analgesics at the right time intervals. With the detailed adherence information from this study, it is possible to further tailor patient education to the individual patient.

RESUMO

PURPOSE: Transdermal fentanyl is effective for the treatment of moderate to severe cancer-related pain but is unsuitable for fast titration. In this setting, continuous subcutaneous fentanyl may be used. As data on the pharmacokinetics of continuous subcutaneous fentanyl are lacking, we studied the pharmacokinetics of subcutaneous and transdermal fentanyl. Furthermore, we evaluated rotations from the subcutaneous to the transdermal route. METHODS: Fifty-two patients treated with subcutaneous and/or transdermal fentanyl for moderate to severe cancer-related pain participated. A population pharmacokinetic model was developed and evaluated using non-linear mixed-effects modelling. For rotations from subcutaneous to transdermal fentanyl, a 1:1 dose conversion ratio was used while the subcutaneous infusion was continued for 12 h (with a 50 % tapering after 6 h). A 6-h scheme with 50 % tapering after 3 h was simulated using the final model. RESULTS: A one-compartment model with first-order elimination and separate first-order absorption processes for each route adequately described the data. The estimated apparent clearance of fentanyl was 49.6 L/h; the absorption rate constant for subcutaneous and transdermal fentanyl was 0.0358 and 0.0135 h(-1), respectively. Moderate to large inter-individual and inter-occasion variability was found. Around rotation from subcutaneous to transdermal fentanyl, measured and simulated plasma fentanyl concentrations rose and increasing side effects were observed. CONCLUSIONS: We describe the pharmacokinetics of subcutaneous and transdermal fentanyl in one patient cohort and report several findings that are relevant for clinical practice. Further research is warranted to study the optimal scheme for rotations from the subcutaneous to the transdermal route.

RESUMO

BACKGROUND: To improve the quality of end-of-life care, hospitals increasingly appoint palliative care nurse champions. AIM: We investigated the effect of nurse champions on the quality of life during the last 3 days of life and the quality of dying as experienced by bereaved relatives. DESIGN: A controlled before-and-after study (June 2009-July 2012). Halfway, in each of seven intervention wards, two nurse champions were appointed; 11 wards served as control wards. The quality of life during the last 3 days of life, quality of dying and multiple dimensions of quality of dying were compared before and after the introduction of nurse champions. SETTING: In a university hospital, each death at non-intensive care units was followed up by an invitation to relatives (10-13 weeks later) to answer a questionnaire. RESULTS: For the two periods, data were collected on 86 and 84 patients in intervention wards and on 108 and 118 patients in control wards (overall response: 52%). In the intervention wards, no differences were found in the quality of life during the last 3 days of life and the quality of dying scores: in both periods, median score for the quality of life during the last 3 days of life was 3.0 and for the quality of dying 7.0. No differences were found in multiple quality of dying dimensions. In control wards, the median quality of dying score was 7.0 pre-intervention and 6.0 post-intervention (p = 0.04). Other scores were comparable with those in intervention wards. CONCLUSION: Performing a complex intervention study in palliative care proved to be feasible. This study showed no differences in the experiences of bereaved relatives after introduction of nurse champions. The complexity of palliative care in the hospital might require more intensive and longer training of nurse champions.

RESUMO

We treated patients with newly diagnosed and large low-grade oligodendroglial tumors with upfront procarbazine, CCNU and vincristine (PCV) in order to delay radiotherapy. Patients were treated with PCV for a maximum of 6 cycles. The response to treatment was defined according to the RANO criteria; in addition change over time of mean tumor diameters (growth kinetics) was calculated. Thirty-two patients were treated between 1998 and 2006, 18 of which were diagnosed with 1p/19q co-deleted tumors. Median follow-up duration was 8 years (range 0.5-13 years). The median overall survival (mOS) was 120 months and the median progression-free survival (mPFS) was 46 months. Growth kinetics showed an ongoing decrease of the mean tumor diameter after completion of chemotherapy, during a median time of 35 months, but an increase of the mean tumor diameter did not herald progression as detected by RANO criteria. 1p/19q co-deletion was associated with a significant increase in OS (mOS 83 months versus not reached for codeleted tumors; p = 0.003)) and PFS (mPFS 35 months versus 67 months for codeleted tumors; p = 0.024). Patients with combined 1p/19q loss had a 10 year PFS of 34 % and the radiotherapy in these patients was postponed for a median period of more than 6 years. This long-term follow-up study indicates that upfront PCV chemotherapy is associated with long PFS and OS and delays radiotherapy for a considerable period of time in patients with low-grade oligodendroglial tumors, in particular with combined 1p/19q loss.

RESUMO

Patients with incurable esophageal cancer (EC) or pancreaticobiliary cancer (PBC) often have multiple symptoms and their quality of life is poor. We investigated which problems these patients experience and how often care is expected for these problems to provide optimal professional care. Fifty-seven patients with incurable EC (N = 24) or PBC (N = 33) from our outpatient clinic completed the validated "Problems and Needs for Palliative Care" (PNPC) questionnaire and two disease-specific quality of life questionnaires, European Organization for Research and Treatment in Cancer (EORTC). Although patients in general had several problems, physical, emotional, and loss of autonomy (LOA) problems were most common. For these physical and emotional problems, patients also expected professional care, although to a lesser extent for LOA problems. Inadequate care was received for fatigue, fear, frustration, and uncertainty. We conclude that an individualized approach based on problems related to physical, emotional, and LOA issues and anticipated problems with healthcare providers has priority in the follow-up policy of patients with incurable upper gastrointestinal cancer. Caregivers should be alert to discuss needs for fatigue, feelings of fear, frustration, and uncertainty.

RESUMO

OBJECTIVE: In the shared decision-making (SDM) process for potential early phase clinical cancer trial participation, value clarification is highly recommended. However, exploration and discussion of patient values between patients and oncologists remains limited. This study aims to develop an SDM-supportive intervention, consisting of a preparatory online value clarification tool (OnVaCT) and a communication training. METHODS: The OnVaCT intervention was developed and pilot-tested by combining theoretical notions on value clarification, with interview studies with patients and oncologists, focus groups with patient representatives and oncologists, and think aloud sessions with patients, following the Medical Research Council (MRC) framework for complex interventions. These human-centered methodologies enabled a user-centered approach at every step of the development process of the intervention. RESULTS: This study shows relevant patient values and oncologists' perspectives on value exploration and discussion in daily practice. This has been combined with theoretical considerations into the creation of characters based on real-life experiences of patients in the OnVaCT, and how the tool is combined with a communication training for oncologists to improve SDM.
