RESUMEN
BACKGROUND: Methylphenidate can be used for the treatment of cancer-related fatigue (CRF), although randomized controlled trials have shown conflicting results. The aim of this study was to use 'real-world' data to evaluate the effect and side effects of using methylphenidate in palliative cancer care with a focus on the late palliative phase and dose-response. METHOD: A retrospective review of medical records from a palliative care unit in Sweden was performed to evaluate the effect and adverse events (AEs) of using methylphenidate to treat CRF. Univariable and multivariable regression was performed and odds ratio (OR) calculated. Adjustments were made for sex, age, cancer type, dose and starting treatment <4 weeks before death. RESULTS: Of the 2,419 screened patients, 112 had been treated with methylphenidate for CRF. The treatment was assessed as being effective in 51 patients (46%). Twenty-six patients (23%) experienced AEs that were generally mild, including anxiety, palpitations, and insomnia. Patients starting the treatment <4 weeks before death (n = 54) were less likely to have an effect from treatment compared to those starting earlier; adjusted OR 0.24 (95% CI 0.10-0.55). Doses of 20 mg and above were well-tolerated and had a higher frequency of effect in the crude data but not after adjustment for confounding factors. CONCLUSION: Methylphenidate is generally effective and well-tolerated for the treatment of CRF in palliative care. However, patients with a short life expectancy (<4 weeks) seem to benefit less from the treatment regardless of age, cancer type and dose.

OBJECTIVES: High-protein parenteral nutrition (PN) has been developed to counteract muscle loss in patients with cancer treated with PN. Nevertheless, it is not clear if high-protein PN is as safe as standard PN in patients with palliative cancer. Our primary aim was to compare the proportion of patients with elevated liver enzymes between high-protein and standard PN in patients with palliative cancer enrolled to Medical Home Care. Our secondary aim was to compare the two treatments with regard to weight and albumin levels during treatment. METHODS: Medical records from 2016 to 2018 were retrospectively reviewed to identify palliative cancer patients that had received PN for more than 3 weeks. Data on weight, height, albumin, liver enzymes, socioeconomic factors and dietitian consultations were collected at baseline and after 3-8 weeks of PN treatment. The odds of having elevated liver enzymes or having a maintained weight and/or stable albumin levels were calculated using logistic regression. RESULTS: 20 patients treated with high-protein PN were compared with 104 patients treated with standard PN. Patients treated with high-protein PN had a significantly higher weight at follow-up compared with patients treated with standard PN (p<0.05). There was no significant difference in the proportion of patients with elevated liver enzymes (OR 0.20; 95% CI 0.02 to 1.86), or maintained weight and/or albumin levels (OR 1.62; 95% CI 0.46 to 5.76) between high-protein and standard PN. CONCLUSION: High-protein PN was as safe, and at least as effective, as standard PN to patients with palliative cancer.

This study sought to determine whether third line therapy with capecitabine (cap.) could provide any clinical benefit in patients with advanced colorectal cancer who have progressed on 5-Fu combination therapy with both irinotecan and oxaliplatin. Twenty patients who were pretreated with and had progressed on irinotecan+Nordic FLv (5-Fu/leukovorin) and oxaliplatin+c.i. 5-Fu/leukovorin were studied. Cap. was administered at 1000-1250 mg/m2 bid d1-14 q 3 w. Time to progression (TTP) (either radiological or clinical) and overall survival (OS) were estimated with the Kaplan-Meier actuarial method. The median number of administered cap. courses was four. No radiological or biochemical responses were observed. Three patients were classified as having stable disease at three months. Two of these patients had, however, minor radiological progression and a =100% increase in CEA compared to base line. Seventeen patients were classified as having progressive disease during the first three months period. Median TTP and OS were 2.8 months and 6.1 months, respectively. A response rate of =15% for third line cap. in metastatic CRC can be ruled out. Median PFS was limited in the study population. This observation and the few cases with SD at three months, lead us to believe that little or no clinical benefit can be expected from single drug cap. in patients with irinotecan- and oxaliplatin-combination resistant advanced colorectal cancer.
