Outcomes and Feasibility of an Occupational Care Programme (TERRA) to Support Work Ability of Rare and Advanced Cancer Patients: A Report of 7 Cases.

INTRODUCTION: Advancements in the field of oncology are allowing patients to live longer, with enhanced quality of life (QoL). Accordingly, more patients with cancer are expressing the desire to return to work (RTW). Previous research has indicated that patients with a rare or advanced cancer can experience unique problems in the RTW process. METHODS: This pilot study evaluated the outcomes and feasibility of the occupational care programme TERRA (i.e., recalibraTe lifE and woRk with and afteR cAncer) for patients with a rare or advanced cancer. Four rare cancer patients and three advanced cancer patients completed TERRA; a supportive occupational care programme consisting of five online group sessions over a two-month period. Pre- and post-intervention outcomes were collected using validated self-report questionnaires. The primary outcome was work ability. Secondary outcomes included QoL, anxiety and depression, fatigue, unmet needs, self-efficacy, readiness for RTW, work intention, work involvement, and work-life conflict. Feasibility was assessed using the RE-AIM model. RESULTS: Changes in work ability scores were inconsistent across participants. Well-being outcomes generally improved following the intervention. Feasibility was evaluated positively by both participants and trainers. DISCUSSION/CONCLUSION: A multidisciplinary approach may further improve outcomes of occupational interventions supporting rare and advanced cancer patients. An effectiveness study to evaluate the outcomes and feasibility of the programme is deemed necessary.

Experiences and perspectives of patients with advanced cancer regarding work resumption and work retention: a qualitative interview study.

PURPOSE: Being able to work improves the quality of life of patients with cancer. Much is known about the return to work process of cancer survivors. Yet, studies focusing on the experiences of patients with advanced cancer who want to return to work or stay employed are scarce. Therefore, we aimed to explore the perceptions of patients with advanced cancer regarding work resumption and work retention and the barriers and facilitators they may experience. METHODS: Semi-structured interviews were conducted. Patients were included if they: (1) were diagnosed with advanced cancer, (2) worked in paid employment at time of diagnosis, and (3) were currently back in paid employment or had the intention to return to paid employment. Participants were recruited through clinicians and patient organizations. Interviews were transcribed and thematically analysed using ATLAS.ti. RESULTS: Fifteen patients (87% female, mean age 52 (SD 4; range 41-64)) were individually interviewed. Four main themes emerged from the data: (1) holding on to normalcy, (2) high understanding and divergent expectations, (3) social discomfort calls for patient-initiated alignment, and (4) laws and regulations require patient empowerment. CONCLUSION: Paid employment can contribute to the quality of life of patients with advanced cancer. The findings of this study might correct erroneous preconceptions about the work ability and work intention of patients with advanced cancer. Tools already developed for employers to support reintegration of patients with cancer should be further explored and translated to patients with advanced cancer.

Metoclopramide, Dexamethasone, or Palonosetron for Prevention of Delayed Chemotherapy-Induced Nausea and Vomiting After Moderately Emetogenic Chemotherapy (MEDEA): A Randomized, Phase III, Noninferiority Trial.

BACKGROUND: For the prevention of chemotherapy-induced nausea and vomiting (CINV) during the delayed phase (24-120 hours) after moderately emetogenic chemotherapy (MEC), the use of 3-day dexamethasone (DEX) is often recommended. This study compared the efficacy and safety of two DEX-sparing regimens with 3-day DEX, focusing on delayed nausea. PATIENTS AND METHODS: This open-label, randomized, phase III study was designed to demonstrate noninferiority of two DEX-sparing regimens: ondansetron + DEX on day 1 + metoclopramide on days 2-3 (MCP arm), and palonosetron + DEX on day 1 (PAL arm) versus ondansetron on day 1 + DEX on days 1-3 (DEX arm) in chemotherapy-naïve patients receiving MEC. Primary efficacy endpoint was total control (TC; no emetic episodes, no use of rescue medication, no nausea) in the delayed phase. Noninferiority was defined as a lower 95% CI greater than the noninferiority margin set at -20%. Secondary endpoints included no vomiting, no rescue medication, no (significant) nausea, impact of CINV on quality of life, and antiemetics-associated side effects. RESULTS: Treatment arms were comparable for 189 patients analyzed: predominantly male (55.7%), median age 65.0 years, colorectal cancer (85.7%), and oxaliplatin-based chemotherapy (81.5%). MCP demonstrated noninferiority to DEX for delayed TC (MCP 56.1% vs. DEX 50.0%; 95% CI, -11.3%, 23.5%). PAL also demonstrated noninferiority to DEX (PAL 55.6% vs. DEX 50.0%; 95% CI, -12.0%, 23.2%). There were no statistically significant differences for all secondary endpoints between treatment arms. CONCLUSION: This study showed that DEX-sparing regimens are noninferior to multiple-day DEX in terms of delayed TC rate in patients undergoing MEC. ClinicalTrials.gov identifier. NCT02135510. IMPLICATIONS FOR PRACTICE: Chemotherapy-induced nausea and vomiting (CINV) in the delayed phase (24-120 hours after chemotherapy) remains one of the most troublesome adverse effects associated with cancer treatment. In particular, delayed nausea is often poorly controlled. The role of dexamethasone (DEX) in the prevention of delayed nausea after moderately emetogenic chemotherapy (MEC) is controversial. This study is the first to include nausea assessment as a part of the primary study outcome to better gauge the effectiveness of CINV control and patients' experience. Results show that a DEX-sparing strategy does not result in any significant loss of overall antiemetic control: DEX-sparing strategies incorporating palonosetron or multiple-day metoclopramide are safe and at least as effective as standard treatment with a 3-day DEX regimen with ondansetron in controlling delayed CINV-and nausea in particular-following MEC.

Olanzapine Versus Haloperidol for Treatment of Delirium in Patients with Advanced Cancer: A Phase III Randomized Clinical Trial.

BACKGROUND: Treatment of delirium often includes haloperidol. Second-generation antipsychotics like olanzapine have emerged as an alternative with possibly fewer side effects. The aim of this multicenter, phase III, randomized clinical trial was to compare the efficacy and tolerability of olanzapine with haloperidol for the treatment of delirium in hospitalized patients with advanced cancer. MATERIALS AND METHODS: Eligible adult patients (≥18 years) with advanced cancer and delirium (Delirium Rating Scale-Revised-98 [DRS-R-98] total score ≥17.75) were randomized 1:1 to receive either haloperidol or olanzapine (age-adjusted, titratable doses). Primary endpoint was delirium response rate (DRR), defined as number of patients with DRS-R-98 severity score <15.25 and ≥4.5 points reduction. Secondary endpoints included time to response (TTR), tolerability, and delirium-related distress. RESULTS: Between January 2011 and June 2016, 98 patients were included in the intention-to-treat analysis. DRR was 45% (95% confidence interval [CI], 31-59) for olanzapine and 57% (95% CI, 43-71) for haloperidol (Δ DRR -12%; odds ratio [OR], 0.61; 95% CI, 0.2-1.4; p = .23). Mean TTR was 4.5 days (95% CI, 3.2-5.9 days) for olanzapine and 2.8 days (95% CI, 1.9-3.7 days; p = .18) for haloperidol. Grade ≥3 treatment-related adverse events occurred in 5 patients (10.2%) and 10 patients (20.4%) in the olanzapine and haloperidol arm, respectively. Distress rates were similar in both groups. The study was terminated early because of futility. CONCLUSION: Delirium treatment with olanzapine in hospitalized patients with advanced cancer did not result in improvement of DRR or TTR compared with haloperidol. Clinical trial identification number. NCT01539733. Dutch Trial Register. NTR2559. IMPLICATIONS FOR PRACTICE: Guidelines recommend that pharmacological interventions for delirium treatment in adults with cancer should be limited to patients who have distressing delirium symptoms. It was suggested that atypical antipsychotics, such as olanzapine, outperform haloperidol in efficacy and safety. However, collective data comparing the efficacy and safety of typical versus atypical antipsychotics in patients with cancer are limited. If targeted and judicious use of antipsychotics is considered for the treatment of delirium in patients with advanced cancer, this study demonstrated that there was no statistically significant difference in response to haloperidol or olanzapine. Olanzapine showed an overall better safety profile compared with haloperidol, although this difference was not statistically significant.

Accuracy of the Delirium Observational Screening Scale (DOS) as a screening tool for delirium in patients with advanced cancer.

BACKGROUND: The Delirium Observation Screening Scale (DOS) was developed to facilitate early recognition of delirium by nurses during routine clinical care. It has shown good validity in a variety of patient populations, but has not yet been validated in hospitalized patients with advanced cancer, although the DOS is commonly used in this setting in daily practice. The aim of this study was to evaluate the accuracy of the DOS in hospitalized patients with advanced cancer using the revised version of the Delirium Rating Scale (DRS-R- 98) as the gold standard. METHODS: Patients with advanced cancer admitted to the medical oncology ward were screened for delirium with the DOS and DRS-R-98. Sensitivity, specificity, negative predictive value (NPV) and positive predictive value (PPV) of the DOS were calculated, using a DOS score ≥ 3 as a cut-off for delirium. RESULTS: Ninety-five DOS negative and 98 DOS positive patients were identified. Sensitivity of the DOS, was > 99.9% (95%-CI, 95.8-100.0%), specificity was 99.5% (95%-CI 95.5-99.96%), PPV was 94.6% (95% CI 88.0-97.7), and NPV was > 99.9% (95% CI 96.1-100.0). CONCLUSIONS: The DOS is an accurate screening tool for delirium in patients with advanced cancer. Since it has the benefit of being easily implicated in daily practice, we recommend to educate caregivers to screen patients with advanced cancer by DOS analysis. By early recognition and adequate treatment of this distressing delirium syndrome the quality of life of patients with advanced cancer can be improved.

Incidence and risk factors for acute kidney injury in head and neck cancer patients treated with concurrent chemoradiation with high-dose cisplatin.

BACKGROUND: Three-weekly high-dose cisplatin (100 mg/m2) is considered the standard systemic regimen given concurrently with postoperative or definitive radiotherapy in locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). Concurrent chemoradiation (CRT) with high-dose cisplatin is associated with significant acute and late toxicities, including acute kidney injury (AKI). The aims of this study were to investigate the incidence of AKI in patients with LA-SCCHN during and after treatment with high-dose cisplatin-based CRT, to identify risk factors for cisplatin-induced AKI, and to describe the impact of AKI on long-term renal function and treatment outcomes. METHODS: This is a retrospective cohort study with measurements of renal function before CRT, weekly during CRT, every 1 or 2 days during hospitalizations, and 3 and 12 months after CRT in patients with LA-SCCHN. AKI was defined as increase in serum creatinine (sCr) of ≥1.5 times baseline or by ≥0.3 mg/dL (≥26.5 µmol/L) using the Kidney Disease Improving Global Outcomes (KDIGO) classification. Logistic regression models were estimated to analyze renal function over time and to identify predictors for AKI. RESULTS: One hundred twenty-four patients completed all measurements. AKI was reported in 85 patients (69%) with 112 episodes of AKI. Sixty of 85 patients experienced 1 AKI episode; 20 patients experienced ≥2 AKI episodes. Ninety-three (83%) AKI episodes were stage 1, 13 (12%) were stage 2, and 6 (5%) AKI episodes were stage 3. Median follow-up time was 29 months (Interquartile Range, IQR 22-33). Hypertension (Odds Ratio, OR 2.7, 95% Confidence Interval, CI 1.1-6.6; p = 0.03), and chemotherapy-induced nausea and vomiting (CINV; OR 4.3, 95% CI 1.6-11.3; p = 0.003) were associated with AKI. In patients with AKI, renal function was significantly more impaired at 3 and 12 months post-treatment compared to patients without AKI. AKI did not have a negative impact on treatment outcomes. CONCLUSION: AKI occurred in 69% of patients with LA-SCCHN undergoing CRT with high-dose cisplatin. Long-term renal function was significantly more impaired in patients with AKI. Hypertension and CINV are significant risk factors. Optimizing prevention strategies for CINV are urgently needed.

Screening and Stepped Care Targeting Psychological Distress in Patients With Metastatic Colorectal Cancer: The TES Cluster Randomized Trial.

BACKGROUND: This study evaluated the effectiveness of a screening and stepped care program (the TES program) in reducing psychological distress compared with care as usual (CAU) in patients with metastatic colorectal cancer starting with first-line systemic palliative treatment. PATIENTS AND METHODS: In this cluster randomized trial, 16 hospitals were assigned to the TES program or CAU. Patients in the TES arm were screened for psychological distress with the Hospital Anxiety and Depression Scale and the Distress Thermometer/Problem List (at baseline and 10 and 18 weeks). Stepped care was offered to patients with distress or expressed needs, and it consisted of watchful waiting, guided self-help, face-to-face problem-solving therapy, or referral to specialized mental healthcare. The primary outcome was change in psychological distress over time, and secondary outcomes were quality of life, satisfaction with care, and recognition and referral of distressed patients by clinicians. Linear mixed models and effect sizes were used to evaluate differences. RESULTS: A total of 349 patients were randomized; 184 received the TES program and 165 received CAU. In the TES arm, 60.3% of the patients screened positive for psychological distress, 26.1% of which entered the stepped care program (14.7% used only watchful waiting and 11.4% used at least one of the other treatment steps). The observed low use of the TES program led us to pursue a futility analysis, which showed a small conditional power and therefore resulted in halted recruitment for this study. No difference was seen in change in psychological distress over time between the 2 groups (effect size, -0.16; 95% CI, -0.35 to 0.03; P>.05). The TES group reported higher satisfaction with the received treatment and better cognitive quality of life (all P<.05). CONCLUSIONS: As a result of the low use of stepped care, a combined screening and treatment program targeting psychological distress in patients with metastatic colorectal cancer did not improve psychological distress. Our results suggest that enhanced evaluation of psychosocial concerns may improve aspects of patient well-being.

Optimal treatment of opioid induced constipation in daily clinical practice - an observational study.

BACKGROUND: Opioids are prescribed in over 40% of patients with advanced cancer, but side effects occur frequently. In this study we evaluated the development and treatment of opioid induced constipation (OIC), and OIC resolving effect of methylnaltrexone for different opioid subtypes in daily clinical practice. METHODS: Patients with cancer using opioids were included in a retrospective chart analysis. Baseline characteristics, data on opioid use, laxative use, and OIC were collected. Patients with OIC who were prescribed methylnaltrexone, were included in a prospective observational trial (NCT01955213). RESULTS: Thirty-nine of 327 patients (pts) with cancer who were treated with opioids suffered from OIC (overall prevalence 12%; 95%-CI: 8-15%). The prevalence of OIC was similar in patients treated with oxycodone or fentanyl (12 of 81 pts. vs. 18 of 110 pts., RR 0.9; 95%CI 0.4-2.0). The morphine equivalent daily dose did not significantly differ between opioid subtypes (fentanyl 89 mg (IQR 60-180) vs. oxycodone 40 mg (40-80), P = 0.231). Twenty-two individual patients (7%) were admitted for OIC. Most effective laxatives in admitted patients were enemas, methylnaltrexone, or 4-l polyethylene-glycol solution. In the prospective observational study, the effect of methylnaltrexone could be evaluated in 23 patients. Eleven patients achieved the primary endpoint of ≥2 laxation responses out of the first four doses methylnaltrexone, independent of opioid subtype. CONCLUSIONS: OIC is a burdensome clinical problem independent of opioid subtype. Timely intensification of prophylactic laxative treatment, especially when opioid doses increase, may help to prevent OIC. Clinically overt OIC requires a more intensive laxative regimen with for example methylnaltrexone. TRIAL REGISTRATION: NCT01955213 .

Radiofrequency Ablation to Improve Survival After Conversion Chemotherapy for Colorectal Liver Metastases.

INTRODUCTION: Systemic chemotherapy is able to convert colorectal liver metastases (CRLM) that are initially unsuitable for local treatment into locally treatable disease. Surgical resection further improves survival in these patients. Our aim was to evaluate disease-free survival (DFS), overall survival, and morbidity for patients with CRLM treated with RFA following effective downstaging by chemotherapy, and to identify factors associated with recurrence and survival. MATERIALS AND METHODS: Included patients had liver-dominant CRLM initially unsuitable for local treatment but eligible for RFA or RFA with resection after downstaging by systemic chemotherapy. Chemotherapeutic regimens consisted predominantly of CapOx, with or without bevacizumab. Follow-up was conducted with PET-CT or thoraco-pelvic CT. RESULTS: Fifty-one patients had a total of 325 CRLM (median = 7). Following chemotherapy, 183 lesions were still visible on CT (median = 3). Twenty-six patients were treated with RFA combined with resection. During surgery, 309 CRLM were retrieved on intraoperative ultrasound (median = 5). Median survival was 49 months and was associated with extrahepatic disease at time of presentation and recurrences after treatment. Estimated cumulative survival at 1, 3 and 4 years was 90, 63 and 45 %, respectively. Median DFS was 6 months. Twelve patients remained free of recurrence after a mean follow-up of 32.6 months. CONCLUSION: RFA of CRLM after conversion chemotherapy provides potential local control and a good overall survival. To prevent undertreatment, the involvement of a multidisciplinary team in follow-up imaging and assessment of local treatment possibilities after palliative chemotherapy for liver-dominant CRLM should always be considered.

Prophylactic treatment for delayed chemotherapy-induced nausea and vomiting after non-AC based moderately emetogenic chemotherapy: a systematic review of randomized controlled trials.

PURPOSE: Delayed chemotherapy-induced nausea and vomiting (CINV) remains an important adverse effect of moderately emetogenic chemotherapy not containing anthracyclines and cyclophosphamide (non-AC MEC). In this review, we summarize current literature to update recommendations for delayed CINV prophylaxis after non-AC MEC. METHODS: We conducted a systematic search in PubMed and conference proceedings from ASCO, ESMO, and MASCC. Included randomized controlled trials (RCTs) aimed to prospectively evaluate the efficacy of two or more antiemetic strategies in the prevention of delayed CINV after the administration of non-AC MEC. At least one of the following endpoints was used: complete response, complete control, no nausea, no vomiting, and/or no use of rescue medication. RESULTS: Our search provided 247 publications. Nine met the predefined criteria. Included RCTs reported outcomes on palonosetron, aprepitant, casopitant, netupitant/palonosetron (NEPA), olanzapine, and megestrol acetate. CONCLUSIONS: Superiority of palonosetron over first-generation 5-HT3 receptor antagonists for the prevention of acute and delayed CINV after non-AC MEC has not been proven. The addition of an NK1 receptor antagonist to first-generation 5-HT3 receptor antagonists does not significantly improve the incidence of delayed CINV after non-AC MEC. The efficacy of a single-day regimen of dexamethasone with palonosetron is non-inferior to multiday dexamethasone. NEPA, olanzapine, and megestrol acetate show highly effective complete response (CR) rates.

Aiming for a better understanding and management of cancer-related fatigue.

Cancer-related fatigue (CRF) is a serious symptom of patients with cancer and deteriorates their daily quality of life. Whereas fatigue is a common problem in the general population, with a prevalence of about 30%, up to 99% of patients with cancer have fatigue of more intense severity. CRF is directly related to the biology of cancer, but it can also be caused by anticancer treatment. We reviewed current evidence about the potential pathophysiological mechanisms causing CRF. Clinical methods to determine the presence and severity of CRF and potential treatment options to reduce CRF will be discussed. After reading this review, the reader will have knowledge of the current understanding of CRF and will be able to give evidence-based advice to patients with CRF.

[Nausea and vomiting after chemotherapy: an ongoing problem for patients]. / Misselijkheid en braken na chemotherapie.

Despite advances in the prevention and management of chemotherapy-induced nausea and vomiting (CINV), these side effects remain among the most distressing for patients. We discuss the systematic review and meta-analysis by Patel et al (2022) evaluating effective and safe interventions to prevent acute phase CINV in adult and pediatric patients. With the advent of newer antiemetics during the last few decades, the incidence of CINV has improved especially for patients receiving highly emetogenic chemotherapy. Control of nausea remains an unmet need. Data on antiemetic safety are lacking. Future research should focus on patients receiving multiple-day chemotherapy, moderately emetogenic chemotherapy, but also on patients treated with low or minimally emetogenic chemotherapy. The identification of patients at high risk for CINV based on key patient-related risk factors prior to the initiation of a chemotherapy regimen is imperative, but in our view, these factors are not adequately taken into account.

Quality of integrated female oncofertility care is suboptimal: A patient-reported measurement.

BACKGROUND: Clinical practice guidelines recommend to inform female cancer patients about their infertility risks due to cancer treatment. Unfortunately, it seems that guideline adherence is suboptimal. In order to improve quality of integrated female oncofertility care, a systematic assessment of current practice is necessary. METHODS: A multicenter cross-sectional survey study in which a set of systematically developed quality indicators was processed, was conducted among female cancer patients (diagnosed in 2016/2017). These indicators represented all domains in oncofertility care; risk communication, referral, counseling, and decision-making. Indicator scores were calculated, and determinants were assessed by multilevel multivariate analyses. RESULTS: One hundred twenty-one out of 344 female cancer patients participated. Eight out of 11 indicators scored below 90% adherence. Of all patients, 72.7% was informed about their infertility, 51.2% was offered a referral, with 18.8% all aspects were discussed in counseling, and 35.5% received written and/or digital information. Patient's age, strength of wish to conceive, time before cancer treatment, and type of healthcare provider significantly influenced the scores of three indicators. CONCLUSIONS: Current quality of female oncofertility care is far from optimal. Therefore, improvement is needed. To achieve this, improvement strategies that are tailored to the identified determinants and to guideline-specific barriers should be developed.

Aberrant immunophenotype of blasts in myelodysplastic syndromes is a clinically relevant biomarker in predicting response to growth factor treatment.

Myelodysplastic syndromes (MDS) are a group of clonal disorders of the bone marrow characterized by peripheral cytopenias. Standard treatment in low- and intermediate-I-risk MDS is supportive therapy consisting of regular transfusions and growth factors, that is, erythropoietin (Epo) and granulocyte-colony-stimulating factor (G-CSF). Because flow cytometric analysis of MDS bone marrow samples can identify clinically relevant subgroups regarding transfusion dependency and disease progression, we addressed the question whether flow cytometry (FCM) was instrumental in predicting response. In 46 patients with low- and intermediate-I-risk MDS that were treated with Epo/G-CSF, low Epo level and low transfusion need were associated with response to Epo/G-CSF. Interestingly, aberrant phenotype of myeloblasts identified nonresponders among patients with the greatest response probability according to the predictive model of Hellström-Lindberg et al. Moreover, aberrant FCM of myeloblasts acted as a significant biomarker for treatment failure in multivariate analysis. A new predictive model based on the basis FCM combined with previously validated Epo levels is proposed defining 3 subgroups with 94%, 17%, and 11% response probability. In conclusion, FCM may add significantly to well-known predictive parameters in selecting MDS patients eligible for Epo/G-CSF treatment. This is of relevance regarding prevention of treatment failure.

The Impact of Palliative Care Team Consultation on Quality of Life of Patients with Advanced Cancer in Dutch Hospitals: An Observational Study.

INTRODUCTION: Experimental studies have shown that palliative care team (PCT) involvement can improve quality of life (QoL) and symptom burden of patients with advanced cancer. It is unclear to what extent this effect is sustained in daily practice of hospital care. OBJECTIVE: This observational study aims to investigate the effect of PCT consultation on QoL and symptom burden of hospitalized patients with advanced cancer in daily practice. METHODS: After admission to 1 of 9 participating hospitals, patients with advanced cancer for whom the attending physician answered "no" to the Surprise Question were invited to complete a questionnaire, including the EORTC QLQ-C15-PAL, at 6 points in time, until 3 months after admission. Outcomes were compared between patients who received PCT consultation and patients who did not, taking into account differences in baseline characteristics. RESULTS: A total of 164 patients consented to participate, of whom 32 received PCT consultation. Of these patients, 108 were able to complete a questionnaire at day 14, of whom 19 after receiving PCT consultation. After adjusting for baseline differences, EORTC QLQ-C15-PAL scores for pain, appetite, and emotional functioning at day 14 were more favorable for patients who received a PCT consultation. CONCLUSION: PCT consultation decreased patients' symptom burden and tends to have a positive effect on QoL of hospitalized patients with advanced cancer, even if the PCT is consulted late in the patient's disease trajectory.

Identification of patients with cancer with a high risk to develop delirium.

Delirium deteriorates the quality of life in patients with cancer, but is frequently underdiagnosed and not adequately treated. In this study, we evaluated the occurrence of delirium and its risk factors in patients admitted to the hospital for treatment or palliative care in order to develop a prediction model to identify patients at high risk for delirium. In a period of 1.5 years, we evaluated the risk of developing delirium in 574 consecutively admitted patients with cancer to our academic oncology department with the Delirium Observation Screening Scale. Risk factors for delirium were extracted from the patient's chart. A delirium prediction algorithm was constructed using tree analysis, and validated with fivefold cross-validation. A total of 574 patients with cancer were acutely (42%) or electively (58%) admitted 1733 times. The incidence rate of delirium was 3.5 per 100 admittances. Tree analysis revealed that the predisposing factors of an unscheduled admittance and a metabolic imbalance accurately predicted the development of delirium. In this group the incidence rate of delirium was 33 per 100 patients (1:3). The AUC of the model was 0.81, and 0.65 after fivefold cross-validation. We identified that especially patients undergoing an unscheduled admittance with a metabolic imbalance do have a clinically relevant high risk to develop a delirium. Based on these factors, we propose to evaluate preventive treatment of these patients when admitted to the hospital in order to improve their quality of life.

Muscle mass as a target to reduce fatigue in patients with advanced cancer.

BACKGROUND: Cancer-related fatigue (CRF) reduces quality of life and the activity level of patients with cancer. Cancer related fatigue can be reduced by exercise interventions that may concurrently increase muscle mass. We hypothesized that low muscle mass is directly related to higher CRF. METHODS: A total of 233 patients with advanced cancer starting palliative chemotherapy for lung, colorectal, breast, or prostate cancer were studied. The skeletal muscle index (SMI) was calculated as the patient's muscle mass on level L3 or T4 of a computed tomography scan, adjusted for height. Fatigue was assessed with the Functional Assessment of Chronic Illness Therapy-fatigue questionnaire (cut-off for fatigue <34). Multiple linear regression analyses were conducted to study the association between SMI and CRF adjusting for relevant confounders. RESULTS: In this group of patients with advanced cancer, the median fatigue score was 36 (interquartile range 26-44). A higher SMI on level L3 was significantly associated with less CRF for men (B 0.447, P 0.004) but not for women (B - 0.401, P 0.090). No association between SMI on level T4 and the Functional Assessment of Chronic Illness Therapy-fatigue score was found (n = 82). CONCLUSIONS: The association between SMI and CRF may lead to the suggestion that male patients may be able to reduce fatigue by exercise interventions aiming at an increased muscle mass. In women with advanced cancer, CRF is more influenced by other causes, because it is not significantly related to muscle mass. To further reduce CRF in both men and women with cancer, multifactorial assessments need to be performed in order to develop effective treatment strategies.

Patients' preferences for participation in treatment decision-making at the end of life: qualitative interviews with advanced cancer patients.

PURPOSE: Patients are often encouraged to participate in treatment decision-making. Most studies on this subject focus on choosing between different curative treatment types. In the last phase of life treatment decisions differ as they often put more emphasis on weighing quantity against quality of life, such as whether or not to start treatment aimed at life prolongation but with the possibility of side effects. This study aimed to obtain insight into cancer patients' preferences and the reasons for patients' preferred role in treatment decision-making at the end of life. METHODS: 28 advanced cancer patients were included at the start of their first line treatment. In-depth interviews were held prior to upcoming treatment decisions whether or not to start a life prolonging treatment. The Control Preference Scale was used to start discussing the extent and type of influence patients wanted to have concerning upcoming treatment decision-making. Interviews were audio taped and transcribed. RESULTS: All patients wanted their physician to participate in the treatment decision-making process. The extent to which patients themselves preferred to participate seemed to depend on how patients saw their own role or assessed their own capabilities for participating in treatment decision-making. Patients foresaw a shift in the preferred level of participation to a more active role depending in the later phase of illness when life prolongation would become more limited and quality of life would become more important. CONCLUSION: Patients vary in how much involvement they would like to have in upcoming treatment decision-making. Individual patients' preferences may change in the course of the illness, with a shift to more active participation in the later phases. Communication about patients' expectations, wishes and preferences for participation in upcoming treatment decisions is of great importance. An approach in which these topics are openly discussed would be beneficial.
