Fear, Pain, Denial, and Spiritual Experiences in Dying Processes.

PURPOSE: Approaching death seems to be associated with physiological/spiritual changes. Trajectories including the physical-psychological-social-spiritual dimension have indicated a terminal drop. Existential suffering or deathbed visions describe complex phenomena. However, interrelationships between different constituent factors (e.g., fear and pain, spiritual experiences and altered consciousness) are largely unknown. We lack deeper understanding of patients' inner processes to which care should respond. In this study, we hypothesized that fear/pain/denial would happen simultaneously and be associated with a transformation of perception from ego-based (pre-transition) to ego-distant perception/consciousness (post-transition) and that spiritual (transcendental) experiences would primarily occur in periods of calmness and post-transition. Parameters for observing transformation of perception (pre-transition, transition itself, and post-transition) were patients' altered awareness of time/space/body and patients' altered social connectedness. METHOD: Two interdisciplinary teams observed 80 dying patients with cancer in palliative units at 2 Swiss cantonal hospitals. We applied participant observation based on semistructured observation protocols, supplemented by the list of analgesic and psychotropic medication. Descriptive statistical analysis and Interpretative Phenomenological Analysis (IPA) were combined. International interdisciplinary experts supported the analysis. RESULTS: Most patients showed at least fear and pain once. Many seemed to have spiritual experiences and to undergo a transformation of perception only partly depending on medication. Line graphs representatively illustrate associations between fear/pain/denial/spiritual experiences and a transformation of perception. No trajectory displayed uninterrupted distress. Many patients seemed to die in peace. Previous near-death or spiritual/mystical experiences may facilitate the dying process. CONCLUSION: Approaching death seems not only characterized by periods of distress but even more by states beyond fear/pain/denial.

The Range of Neurological Complications in Chikungunya Fever.

BACKGROUND: Chikungunya fever is a globally spreading mosquito-borne disease that shows an unexpected neurovirulence. Even though the neurological complications have been a major cause of intensive care unit admission and death, to date, there is no systematic analysis of their spectrum available. OBJECTIVE: To review evidence of neurological manifestations in Chikungunya fever and map their epidemiology, clinical spectrum, pathomechanisms, diagnostics, therapies and outcomes. METHODS: Case report and systematic review of the literature followed established guidelines. All cases found were assessed using a 5-step clinical diagnostic algorithm assigning categories A-C, category A representing the highest level of quality. Only A and B cases were considered for further analysis. After general analysis, cases were clustered according to geospatial criteria for subgroup analysis. RESULTS: Thirty-six of 1196 studies were included, yielding 130 cases. Nine were ranked as category A (diagnosis of Neuro-Chikungunya probable), 55 as B (plausible), and 51 as C (disputable). In 15 cases, alternative diagnoses were more likely. Patient age distribution was bimodal with a mean of 49 years and a second peak in infants. Fifty percent of the cases occurred in patients <45 years with no reported comorbidity. Frequent diagnoses were encephalitis, optic neuropathy, neuroretinitis, and Guillain-Barré syndrome. Neurologic conditions showing characteristics of a direct viral pathomechanism showed a peak in infants and a second one in elder patients, and complications and neurologic sequelae were more frequent in these groups. Autoimmune-mediated conditions appeared mainly in patients over 20 years and tended to show longer latencies and better outcomes. Geospatial subgrouping of case reports from either India or Réunion revealed diverging phenotypic trends (Réunion: 88% direct viral vs. India: 81% autoimmune). CONCLUSIONS: Direct viral forms of Neuro-Chikungunya seem to occur particularly in infants and elderly patients, while autoimmune forms have to be also considered in middle-aged, previously healthy patients, especially after an asymptomatic interval. This knowledge will help to identify future Neuro-Chikungunya cases and to improve outcome especially in autoimmune-mediated conditions. The genetics of Chikungunya virus might play a key role in determining the course of neuropathogenesis. With further research, this could prove diagnostically significant.

Epidermal growth factor receptor and anaplastic lymphoma kinase testing and mutation prevalence in patients with advanced non-small cell lung cancer in Switzerland: A comprehensive evaluation of real world practices.

In order to improve outcomes, identification of the epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) genes has become crucial in advanced non-small-cell lung cancer (NSCLC). The aim of the present study is to analyse time trends and frequency of testing, factors affecting testing as well as prevalence of mutations in the Swiss population. We analysed EGFR and ALK testing in a cohort of patients with newly diagnosed metastasised non-squamous NSCLC in the catchment area of the cancer registry Eastern Switzerland in the years 2008-2014. We analysed prevalence of mutations and studied clinicopathological characteristics and survival of tested and non-tested patients and of patients with and without mutations. Among 718 patients identified, 11% (51/447) harboured an EGFR mutation in the exons 18, 19 or 21 and further 12% (31/265) showed a positive test result for ALK rearrangements. In non-smokers the proportions of mutations were 31% and 23% respectively. Testing rates increased over time and reached 79% in 2014. We observed significantly lower testing rates and poorer survival in elderly, patients with limited life expectancy and patients treated at hospitals not involved in clinical research. Outcomes can be further improved in a considerable proportion of patients with advanced non-squamous NSCLC.

Erlotinib has comparable clinical efficacy to chemotherapy in pretreated patients with advanced non-small cell lung cancer (NSCLC): A propensity-adjusted, outcomes research-based study.

OBJECTIVES: Controversy exists about the integration of erlotinib in patients with EGFR wildtype, advanced NSCLC. MATERIALS AND METHODS: We included patients with advanced NSCLC receiving at least two lines of palliative systemic treatment between January 2005 and December 2014 and not harbouring targetable driver mutations. Primary study endpoint was overall survival (OS), secondary endpoint progression-free survival (PFS). We used Kaplan-Meier statistics, multivariate Cox regression and Propensity score or Inverse Probability Weights (IPW) matching to compare clinical outcome between patients receiving erlotinib in second or further line and those receiving chemotherapy only. The study had a power of 90% to detect a survival superiority of 30%. RESULTS: From a total of 827 patients, we excluded 171 patients with potentially curative treatment, 189 receiving treatment outside of our institute, 206 receiving no or only one line of systemic treatment, 6 with ALK translocations and 28 with EGFR mutations. From 227 patients in the final efficacy analysis, 125 patients received erlotinib in second (89 patients), third (28) or further-line (8), and 102 patients received chemotherapy only. Women and never smokers were significantly overrepresented in the erlotinib group. Both OS (hazard ratio (HR)=1.14, 95% CI 0.80-1.63, P=0.448) and PFS (HR=1.20, 95% CI 0.95-1.52, P=0.119) were similar in the erlotinib compared to the chemotherapy group using IPW-adjusted Cox regression analysis treating the use of erlotinib as a time-dependent covariate starting from second-line treatment and stratified for ECOG performance status and treatment line. ECOG performance status was the most powerful covariate to select patients for erlotinib treatment. CONCLUSION: The present study suggests erlotinib to have similar clinical efficacy compared to chemotherapy in patients with pretreated advanced NSCLC and no known molecular targetable alterations.

Germline TYMS genotype is highly predictive in patients with metastatic gastrointestinal malignancies receiving capecitabine-based chemotherapy.

PURPOSE: This work was initiated to extend data on the effect of pharmacogenetics and chemotherapy pharmacokinetics (PK) on clinical outcome in patients with gastrointestinal malignancies. METHODS: We assessed 44 gene polymorphisms in 16 genes (TYMS, MTHFR, GSTP1, GSTM1, GSTT1, DPYD, XRCC1, XRCC3, XPD, ERCC1, RECQ1, RAD54L, ABCB1, ABCC2, ABCG2 and UGT2B7) in 64 patients with metastatic colorectal cancer (CRC) receiving capecitabine/oxaliplatin and 76 patients with advanced gastroesophageal cancer (GEC) receiving epirubicin/cisplatin/capecitabine, respectively. Plasma concentrations of anticancer drugs were measured for up to 24 h, and results were submitted to population PK analysis. We calculated the association between gene polymorphisms, chemotherapy exposure, tumor response, progression-free survival (PFS), overall survival (OS) and chemotherapy-related toxicity using appropriate statistical tests. RESULTS: Patients with a low clearance of 5FU were at increased risk of neutropenia (P < 0.05) and hand-foot syndrome (P = 0.002). DPYD T85C, T1896C and A2846T mutant variants were associated with diarrhea (P < 0.05) and HFS (P < 0.02), and IVS14+1G>A additionally with diarrhea (P < 0.001). The TYMS 2R/3G, 3C/3G or 3G/3G promoter variants were associated with worse PFS in the CRC (HR = 2.0, P < 0.01) and GEC group (HR = 5.4, P < 0.001) and worse OS in the GEC group (HR = 4.7, P < 0.001). The GSTP1 A313G mutant variant was associated with a higher PFS (HR = 0.55, P = 0.001) and OS (HR = 0.60, P = 0.002) in the CRC group. CONCLUSIONS: Germline polymorphisms of DPYD, TYMS and GSTP1 have a significant effect on toxicity and clinical outcome in patients receiving capecitabine-based chemotherapy for advanced colorectal or gastroesophageal cancer. These data should further be validated in prospective clinical studies.

Spiritual experiences of transcendence in patients with advanced cancer.

PURPOSE: Spirituality encompasses a wide range of meanings between holistic wellbeing and mysticism. We explored advanced cancer patients' spiritual experiences of transcendence. METHODS: A total of 251 patients with advanced cancer were included and observed (participant observation) over 12 months by a psycho-oncologist/music-therapist. She recorded and documented patients' spontaneously expressed spiritual experiences during hospitalisation. Interpretative Phenomenological Analysis was applied. RESULTS: 135 patients communicated a spiritual experience, as expressed by altered body-awareness, less pain, less anxiety, higher acceptance of illness/death, new spiritual identity. Spiritual experiences were communicated by patients across different religious affiliations/attitudes. We identified types of spiritual experiences. CONCLUSION: The occurrence of spiritual experiences seems to be frequent and associated with profound, powerful reactions. Our results indicate that experienced-based spiritual care may complement current needs-based approaches.

Discrete improvement in racial disparity in survival among patients with stage IV colorectal cancer: a 21-year population-based analysis.

PURPOSE: Recently, multiple clinical trials have demonstrated improved outcomes in patients with metastatic colorectal cancer. This study investigated if the improved survival is race dependent. PATIENTS AND METHODS: Overall and cancer-specific survival of 77,490 White and Black patients with metastatic colorectal cancer from the 1988-2008 Surveillance Epidemiology and End Results registry were compared using unadjusted and multivariable adjusted Cox proportional hazard regression as well as competing risk analyses. RESULTS: Median age was 69 years, 47.4 % were female and 86.0 % White. Median survival was 11 months overall, with an overall increase from 8 to 14 months between 1988 and 2008. Overall survival increased from 8 to 14 months for White, and from 6 to 13 months for Black patients. After multivariable adjustment, the following parameters were associated with better survival: White, female, younger, better educated and married patients, patients with higher income and living in urban areas, patients with rectosigmoid junction and rectal cancer, undergoing cancer-directed surgery, having well/moderately differentiated, and N0 tumors (p < 0.05 for all covariates). Discrepancies in overall survival based on race did not change significantly over time; however, there was a significant decrease of cancer-specific survival discrepancies over time between White and Black patients with a hazard ratio of 0.995 (95 % confidence interval 0.991-1.000) per year (p = 0.03). CONCLUSION: A clinically relevant overall survival increase was found from 1988 to 2008 in this population-based analysis for both White and Black patients with metastatic colorectal cancer. Although both White and Black patients benefitted from this improvement, a slight discrepancy between the two groups remained.

Off-label use of anticancer drugs in eastern Switzerland: a population-based prospective cohort study.

PURPOSE: Prevalence data on the off-label use (OLU) of anticancer drugs are limited despite OLU being controversial for medical, pharmaco-economic, and ethical reasons. We therefore quantified and characterized the OLU of anticancer drugs and compared OLU based on the national drug label with international treatment recommendations. METHODS: We prospectively collected data on patients receiving systemic anticancer therapy between October and December 2012 at hospitals affiliated with the Eastern Switzerland Oncology Network. Individual data on patient characteristics, tumor disease, and systemic treatment were collected, and each individual treatment was compared with the national drug label and international treatment guidelines. RESULTS: A total of 985 consecutive patients receiving 1,737 anticancer drug treatments were included in the study. Overall, 32.4 % of all patients received at least one off-label drug, corresponding to 27.2 % of all anticancer drugs administered. Major reasons for OLU were the lack of approval for the specific disease entity (15.7 %) and modified application of the anticancer drug (10 %). OLU that was unsupported by the current European Society for Medical Oncology (ESMO) treatment recommendations was rare (6.6 %) but higher for bevacizumab (29.6 %) due to its use in treating advanced ovarian cancer beyond the second-line setting and advanced breast cancer beyond the first-line setting and for lenalidomide (22.6 %) due to its use in treating Non-Hodgkin lymphoma. CONCLUSIONS: Based on data collected on our patient cohort, OLU of anticancer drugs in a European clinical setting applies to one-third of all cancer patients. ESMO-unsupported use of chemotherapies or molecularly-targeted drugs is rare, opposing concerns that the off-label use of newer anticancer drugs is a substantial clinical problem.

Safety and pharmacology of gemcitabine and capecitabine in patients with advanced pancreatico-biliary cancer and hepatic dysfunction.

PURPOSE: We assessed the impact of hepatic dysfunction on the safety and pharmacology of gemcitabine/capecitabine in patients with advanced pancreatico-biliary cancer. METHODS: We included 12 patients receiving 3 weekly gemcitabine 1,000 mg/m(2) day 1, 8 and oral capecitabine 650 mg/m(2) b.i.d. over 2 weeks until disease progression or intolerable toxicity. Patients were included into one normal hepatic function cohort [total bilirubin (TB) ≤15 µmol/L] and 3 cohorts with increasing TB (16-39, 40-80, >80 µmol/L). Three patients with a creatinine clearance <60 ml/min were also included. Patients were sampled for gemcitabine, difluoro-deoxy uridine, intracellular gemcitabine triphosphates, capecitabine, 5'-deoxy-5-fluorocytidine, 5'-deoxy-5-fluorouridine and 5-fluorouracil up to 4 h after initiation of chemotherapy on day 1, and up to 90 min on day 8. All compounds were analyzed using validated liquid chromatography-tandem mass spectrometry. Nonlinear mixed-effect modeling was used for population analysis. RESULTS: Hepatic dysfunction was caused by intrahepatic cholestasis in 4 out of 8 patients (50 %) and extrahepatic cholestasis in another 4 patients (50 %). Dose-limiting toxicity was increasing hyperbilirubinemia and severe neutropenia in 2 patients each. Hepatic dysfunction was not associated with dose-limiting toxicity or severe hematological or non-hematological toxicity. However, hepatic dysfunction was associated with low clearance of both gemcitabine (p = 10(-3)) and capecitabine (p = 10(-5)), and low intracellular gemcitabine triphosphate concentrations (p = 10(-3)). CONCLUSIONS: Gemcitabine/capecitabine can be given at the standard dose in patients with severe hyperbilirubinemia, though the present data suggest that gemcitabine's activity may be limited due to poor intracellular activation. In patients with severe hyperbilirubinemia, initial monotherapy with capecitabine should be considered, followed by the addition of gemcitabine with improving hyperbilirubinemia.

Management of elderly patients with advanced non-small cell lung cancer: a single-center experience.

BACKGROUND: Optimal management of elderly patients (≥70 years) with non-small cell lung cancer (NSCLC) remains debatable. We compared survival and treatment of advanced NSCLC between elderly and younger patients. METHODS: From the cancer registry, we identified 188 patients treated with chemotherapy for stage IV NSCLC. Patient characteristics, survival, toxicity, chemotherapy regimen and response were compared between age groups (patients 50-69 vs. ≥70 years). RESULTS: There were 96 young and 92 elderly patients. The majority were male (70%) and had adenocarcinoma (53%). More elderly had an ECOG performance status >1 (59 vs. 42%, p = 0.04). Median survival was longer for young patients (11.5 vs. 10.8 months, hazard ratio, HR 1.43, p = 0.04). Patients ≥75 years had a significantly worse outcome compared to the young and patients aged 70-74 years (11.5 vs. 12.8 vs. 7.7 months, HR 1.71, p = 0.01). Hospitalization rate did not differ. Elderly had more hematological toxicities (56 vs. 32%, p = 0.01) and less frequently received first-line platinum combinations (96 vs. 69%, p < 0.001). CONCLUSIONS: Elderly patients had a marginally worse survival compared to young patients. Despite the less frequent use of combination chemotherapy, elderly patients experienced toxicity more often. Survival of those ≥75 years was significantly worse, indicating the urgent need of further research particularly in this age group.

Elevated preoperative CEA is associated with worse survival in stage I-III rectal cancer patients.

BACKGROUND: The objective of this investigation was to assess whether preoperative carcinoembryonic antigen (CEA) level is an independent predictor of overall survival in rectal cancer patients. METHODS: All patients (n=504) undergoing a resection for stage I-III rectal cancer at the Kantonsspital St Gallen were included into a database between 1991 and 2008. The impact of preoperative CEA level on overall survival was assessed using risk-adjusted Cox proportional hazard regression models and propensity score methods. RESULTS: In risk-adjusted Cox proportional hazard regression analyses, preoperative CEA level (hazard ratio (HR): 1.98, 95% confidence interval (CI): 1.36-2.90, P<0.001), distance from anal verge (<5 cm: HR: 1.93, 95% CI: 1.11-3.37; P=0.039), older age (HR: 1.07, 95% CI: 1.05-1.09; P<0.001), lower body mass index (HR: 0.94, 95% CI: 0.89-0.98; P=0.006), advanced tumour stage (stage II HR: 1.41, 95% CI: 0.85-2.32; stage III HR: 2.08, 95% CI: 1.31-3.31; P=0.004), R 1 resection (HR: 5.65, 95% CI: 1.59-20.1; P=0.005) and chronic kidney disease (HR: 2.28, 95% CI: 1.03-5.04; P=0.049) were all predictors for poor overall survival. CONCLUSION: This is one of the first investigations based on a large cohort of exclusively rectal cancer patients demonstrating that preoperative CEA level is a strong predictor of decreased overall survival. Preoperative CEA should be used as a prognostic factor in the preoperative assessment of rectal cancer patients.

Methotrexate area under the curve is an important outcome predictor in patients with primary CNS lymphoma: A pharmacokinetic-pharmacodynamic analysis from the IELSG no. 20 trial.

BACKGROUND: This analysis was initiated to define the predictive value of the area under the curve of high-dose methotrexate (AUC(HD-MTX)) in patients with primary central nervous system lymphoma (PCNSL). PATIENTS AND METHODS: We included 55 patients with PCNSL and available pharmacokinetic (PK) data from the International Extranodal Lymphoma Study Group (IELSG) no. 20 trial, randomised to HD-MTX (n=30) or HD-MTX and high-dose cytarabine (HD-AraC) (n=25). Individual AUC(HD-MTX) from population PK analysis was tested on drug toxicity and clinical outcome using multivariate logistic regression analysis and Cox hazards modelling. RESULTS: AUC(HD-MTX), the IELSG score and treatment group were significant predictors for treatment response (complete or partial) in the adjusted model. The AUC(HD-MTX) did not predict toxicity, with the exception of liver toxicity and neutropaenia. A high AUC(HD-MTX) was associated with better event-free survival (EFS) (P=0.01) and overall survival (OAS) (P=0.02). Both the AUC(HD-MTX) and the IELSG score were significant predictors of EFS and OAS in the adjusted model, with a hazard ratio of 0.82 and 0.73, respectively, per 100 micromol l(-1) h(-1) increase in AUC(HD-MTX). CONCLUSIONS: Individualised dosing of HD-MTX might have the potential to improve clinical outcome in patients with PCNSL, even when administered concurrently with HD-AraC. In the future, this could be carried out by using first-cycle PK modelling with determination of potential dose adaptations for later cycles using Bayesian analysis.

The role of pemetrexed in advanced non small-cell lung cancer: special focus on pharmacology and mechanism of action.

Pemetrexed is a newer antifolate drug that has been approved as first-line treatment for patients with advanced non-squamous, non-small cell lung cancer (NSCLC) in combination with cisplatin, and as single agent for relapsed or chemotherapy refractory NSCLC after platinum-containing chemotherapy, at a dose of 500 mg/m(2). Pemetrexed undergoes intracellular activation by poly-gamma-glutamylation, that is essential for its antiproliferative activity. Polyglutamate derivatives mainly inhibit three key enzymes of intracellular folate metabolism, i.e. thymidylates synthase (TYMS), dihydrofolate reductase (DHFR), and glycinamide ribonucleotide formyltransferase (GARFT), with TYMS being the most relevant target. Pemetrexed undergoes rapid renal elimination as unchanged parent compound, with a terminal half-life of between two to five hours. In later clinical development, the usefulness of supplementation with folic acid and vitamin B(12) became evident, to control pemetrexed-related toxicity. The results from the phase III upfront registration study, a retrospective observational data, and a recent maintenance study of pemetrexed in NSCLC suggest histological subtype to be the most important predictive marker for clinical outcome in patients receiving pemetrexed, Pemetrexed is active in patients with non-squamous cell NSCLC while no benefit is seen in patients with squamous-cell histology, possibly as a result of different expression of intratumoral TYMS. These are important steps towards individualisation of anticancer treatment in patients with advanced NSCLC.

Activity of pemetrexed against brain metastases in a patient with adenocarcinoma of the lung.

A 53-year-old woman was with adenocarcinoma of the lung metastatic to the brain was treated after several lines of chemotherapy with pemetrexed. After six cycles an impressive regression of the brain metastases was documented. A brief review of the literature on response of cerebral metastases to chemotherapy is added.

Two-weekly gemcitabine fixed dose rate and oxaliplatin combination chemotherapy for advanced non-small-cell lung cancer.

PURPOSE: Combination chemotherapy with gemcitabine and oxaliplatin (GEMOX) is active in patients with advanced non-small-cell lung cancer (NSCLC). Oxaliplatin has a favourable toxicity profile compared to cisplatin. Gemcitabine's cellular uptake mechanism is saturable and fixed dose rate (FDR) infusion results in higher intracellular concentrations. We evaluated the feasibility, response rate and toxicity of bi-weekly GEMOX. PATIENTS AND METHODS: Eligible patients with inoperable stage IIIB and IV NSCLC were treated with gemcitabine 1200mg/m(2) FDR and oxaliplatin 85mg/m(2), both given on d1 and d15 every 4 weeks for a maximum of six cycles. Tumour response was assessed every 8 weeks using RECIST criteria. RESULTS: Forty eligible patients initiated treatment between December 2002 and December 2004. There were nine partial responses (23%). An additional 23 patients (58%) had stable disease, resulting in a disease stabilization rate of 81%. The time to progression was 7.3 months (95% CI, 6.0-8.2 months). Median survival time was 10.4 months (95% CI, 8.7-13.2 months). The 1 and 2-year survival rates were 42% and 12%, respectively. The time to treatment response was 2.2 months (95% CI, 1.8-3.5 months) with a median response duration of 4 months. The most common grade 3 or higher toxicities were leucopenia (20%), asthenia (15%) and neurotoxicity (10%). There were no treatment-related deaths. Patients with performance status (PS) of 0 had a significantly longer survival than patients with higher PS (12.9 months versus 9.4 months, HR 0.45, P=0.03). CONCLUSION: Bi-weekly GEMOX is active and well tolerated for chemotherapy-naïve patients with advanced NSCLC. This regimen merits consideration for further investigation.

Safety, tolerability and pharmacokinetics of intravenous ghrelin for cancer-related anorexia/cachexia: a randomised, placebo-controlled, double-blind, double-crossover study.

Twenty-one adult patients were randomised to receive ghrelin on days 1 and 8 and placebo on days 4 and 11 or vice versa, given intravenously over a 60-min period before lunch: 10 received 2 microg kg(-1) (lower-dose) ghrelin; 11 received 8 microg kg(-1) (upper-dose) ghrelin. Active and total ghrelin, growth hormone (GH), and insulin-like growth factor 1 levels were monitored at baseline (4-5 days before day 1), during treatment days, and at end of study (day 17/18). Drug-related adverse events (assessed by NCI-CTC-toxicity criteria and cardiac examination) did not differ between ghrelin and placebo. No grade 3/4 toxicity or stimulation of tumour growth was observed. The peak increase of GH, a biological marker of ghrelin action, was 25 ng ml(-1) with lower-dose and 42 ng ml(-1) with upper-dose ghrelin. Morning fasting total ghrelin levels were higher (P<0.05) for upper-dose patients at end of study (3580 pg ml(-1)) than at baseline (990 pg ml(-1)). Insulin-like growth factor 1 levels did not change. At day 8, 81% of patients preferred ghrelin to placebo as against 63% at the end of study. Nutritional intake and eating-related symptoms, measured to explore preliminary efficacy, did not differ between ghrelin and placebo. Ghrelin is well tolerated and safe in patients with advanced cancer. For safety, tolerance, and patients' preference for treatment, no difference was observed between the lower- and upper-dose group.

Fighting a losing battle: eating-related distress of men with advanced cancer and their female partners. A mixed-methods study.

BACKGROUND: Anorexia/cachexia is a frequent complication of advanced cancer with poorly understood psychosocial impact or eating-related distress (ERD) on both patients and family members. To assist palliative care practitioners manage this important psychosocial aspect of care, we aimed to discover and describe elements of ERD, focusing on male patients with advanced cancer and their female partners. METHODS: Nineteen male patients and their partners were systematically investigated by (1) focus group interviews and data analysis inspired by Grounded Theory, and (2) a comparative survey with categorical questions. RESULTS: For patients, eating-related distress was characterised by obstruction to eating, poor and capricious appetite, a disconnection of oral intake and ability to gain weight, and continuous efforts to eat. Partners expressed feelings of deep concern, frustration, and insufficiency in their loving and innovative efforts to prepare appealing food. Partners were more concerned about patients' weight loss than patients themselves (P =0.002). Patients felt more pressure to eat from partners than they estimated (P =0.007). CONCLUSION: Anorexia/cachexia of male cancer patients affects the cooking at home, a couple's daily eating routines, and their spousal relationship. Identification of ERD may trigger targeted psychosocial interventions.

Concerted escalation of dose and dosing duration in a phase I study of the oral camptothecin gimatecan (ST1481) in patients with advanced solid tumors.

BACKGROUND: Gimatecan is an orally bioavailable camptothecin analogue with preclinical findings of promising antitumor activity. A phase I design of concerted dose escalation and dosing duration was implemented to assess the potential schedule dependency of tolerability that emerged from animal studies. PATIENTS AND METHODS: Gimatecan was given daily for five consecutive days per week for 1, 2 or 3 weeks every 28 days. Plasma levels of total gimatecan were measured on the first and the last day of treatment in each schedule. RESULTS: Overall, 108 patients were treated with 0.8-7.2 mg/m(2) of gimatecan per cycle. The main toxicity was myelosuppression with dose-limiting thrombocytopenia. In the 1-, 2- and 3-week schedule, the maximum tolerated doses were 4.5, 5.6 and 6.4 mg/m(2). Diarrhea and asthenia were of low grade and of minor clinical relevance, while the higher incidence of nausea and vomiting in the 1-week schedule required the use of antiemetic prophylaxis. Due to the prolonged half-life (approximately 77 h), the plasma concentration of gimatecan increased from the first to the last day of dosing. Six partial responses were observed. CONCLUSIONS: Tolerability of gimatecan was schedule dependent. Further testing with schedules taking into account its long persistence in human plasma is worthwhile.

Treatment of advanced soft-tissue sarcomas using a combined strategy of high-dose ifosfamide, high-dose doxorubicin and salvage therapies.

Having determined in a phase I study the maximum tolerated dose of high-dose ifosfamide combined with high-dose doxorubicin, we now report the long-term results of a phase II trial in advanced soft-tissue sarcomas. Forty-six patients with locally advanced or metastatic soft-tissue sarcomas were included, with age <60 years and all except one in good performance status (0 or 1). The chemotherapy treatment consisted of ifosfamide 10 g m(-2) (continuous infusion for 5 days), doxorubicin 30 mg m(-2) day(-1) x 3 (total dose 90 mg m(-2)), mesna and granulocyte-colony stimulating factor. Cycles were repeated every 21 days. A median of 4 (1-6) cycles per patient was administered. Twenty-two patients responded to therapy, including three complete responders and 19 partial responders for an overall response rate of 48% (95% CI: 33-63%). The response rate was not different between localised and metastatic diseases or between histological types, but was higher in grade 3 tumours. Median overall survival was 19 months. Salvage therapies (surgery and/or radiotherapy) were performed in 43% of patients and found to be the most significant predictor for favourable survival (exploratory multivariate analysis). Haematological toxicity was severe, including grade > or =3 neutropenia in 59%, thrombopenia in 39% and anaemia in 27% of cycles. Three patients experienced grade 3 neurotoxicity and one patient died of septic shock. This high-dose regimen is toxic but nonetheless feasible in multicentre settings in non elderly patients with good performance status. A high response rate was obtained. Prolonged survival was mainly a function of salvage therapies.
