RESUMO
Background: Nivolumab improved patients' survival in metastatic renal cell carcinoma (mRCC). We aimed to evaluate resting energy expenditure (REE) (i.e., patients' basal metabolism) to predict efficacy. Methods: We conducted a monocentric, observational study of mRCC patients receiving nivolumab between October 2015 and May 2020. REE was measured prior to initiating immunotherapy using indirect calorimetry to determine hypo, normo and hypermetabolism. Primary endpoint was 6-month, progression-free survival (PFS), and secondary endpoints were response rate, PFS and overall survival (OS). Results: Of the 51 consecutive patients, 15 (29%) were hypermetabolic, 24 (47%) normometabolic, and 12 (24%) hypometabolic. The 6-month PFS was 15% for hypermetabolic patients and 65% for non-hypermetabolic patients (p < 0.01). In the multivariate analysis, hypermetabolism was the only baseline factor predicting 6-month PFS (OR 9.91, 95%CI [1.62−60.55], p = 0.01). Disease progression was noted as the best response in 73% of hypermetabolic patients and 26% of non-hypermetabolic patients (p = 0.02). Median PFS was 2.8 and 8.7 months (p < 0.01), and median OS was 20.2 and 35.1 months (p = 0.13) in the hypermetabolic and non-hypermetabolic groups, respectively. Conclusions: Our study identifies an association between mRCC patients' energy expenditure and nivolumab efficacy. The measurement of REE by indirect calorimetry in routine practice could help identify patients at risk of nivolumab failure.
RESUMO
BACKGROUND & AIMS: Predicting the risk of early limiting toxicity (ELT) is major challenge for the clinician seeking an effective, safe treatment for older patients with cancer. The Cancer and Aging Research Group (CARG) and CRASH (Chemotherapy Risk Assessment Scale for High-Age Patients) toxicity scores were designed to predict chemotherapy-related toxicity. Elevated resting energy expenditure (REE) may predispose to cachexia and increase ELT and mortality in older patients with cancer. The primary objective was to assess the association between elevated REE and ELT in older patients with cancer. The secondary objectives were to assess the discriminant ability of a predictive model including REE (relative to the CARG and CRASH scores) and the prognostic value of elevated REE. METHODS: We assessed patients aged 70 or over included in the prospective ELCAPA cohort between 2014 and 2018. The inclusion criteria were a solid tumour, a measurement of REE at baseline (mREE, by indirect calorimetry), and a geriatric assessment prior to cancer treatment in a teaching hospital (Paris, France). The mREE was compared with the predicted REE (pREE), as defined by the Harris-Benedict equation. Depending on the mREE/pREE ratio, study participants were classified as hypermetabolic, hypometabolic or normometabolic. The primary endpoint was 3-month ELT, defined as any unplanned hospitalization or any event leading to dose reduction, a treatment delay of more than 7 days, or treatment discontinuation within 3 months of initiation. The secondary endpoint was the 3-month mortality rate. RESULTS: A total of 179 patients were included. The median age was 80 [interquartile range: 76-84] years, 37% of the patients were female, 81.8% had metastatic disease, 67.6% received chemotherapy, 20.7% received hormone therapy, and 11.7% received targeted therapies. According to the mREE/pREE ratio, 85 patients (47%) were hypermetabolic, 63 (35%) were normometabolic, and 31 (18%) were hypometabolic. Sixty patients (33.5%; 95% confidence interval (CI): 26.7-40.9) experienced ELT. The discriminant ability (as assessed by the C-index) of a multivariate model including REE and adjustment factors was 0.82 [95%CI: 0.73-0.91]. In comparison, the discriminant ability of the CARG and CRASH models was 0.57 [0.45-0.68] and 0.51 [0.40-0.62], respectively. In our model, hypermetabolism was an independent risk factor for ELT (adjusted odds ratio = 2.44; 95%CI: 1.02-5.80). Other risk factors were the cancer type and stage, the treatment protocol, a clinical diagnosis of depression, the presence of grade 3 or 4 comorbidities, and the serum lactate dehydrogenase level. CONCLUSION: Hypermetabolism status is an independent predictor of ELT in older patients with cancer, relative to normometabolic status. Baseline REE measurement might improve the ELT risk assessment and decision-making process.

BACKGROUND: The risk of drug-drug interactions (DDI) has become a major issue in cancer patients. However, data in sarcoma patients are scarce. We aimed to evaluate the frequency and the factors associated with DDI with antitumor treatments, and to evaluate the impact of a pharmacist evaluation before anticancer treatment. PATIENTS AND METHODS: We performed a retrospective review of consecutive sarcoma patients starting chemotherapy (CT) or Tyrosine kinase inhibitor (TKI). A pharmacist performed medication reconciliation and established an early toxicity risk assessment. Potential DDI with antitumor drugs were identified using Micromedex electronic software. RESULTS: One hundred and twenty-two soft-tissue and 80 bone sarcoma patients (103 males, median age 50 years,) were included before CT (86%) or TKI (14%). The median number of medications was 3; 34 patients (22% of patients with medication reconciliation) reported complementary medicine use. 37 potential DDI classified as major, were identified (12% of the 243 pre-therapeutic assessments). In multivariate analysis, TKI (p < 0.0001), proton pump inhibitor (p = 0.026) and antidepressant (p < 0.001) were identified as risk factors of DDI (p < 0.02). Only marital status (p = 0.003) was associated with complementary medicine use. A pharmacist performed 157 medication reconciliations and made 71 interventions among 59 patients (37%). In multivariate analysis, factors associated with pharmacist intervention were: complementary medicines (p = 0.004), drugs number (p = 0.005) and treatment with TKI (p = 0.0002) CONCLUSIONS: Clinical interventions on DDI are more frequently required among sarcoma patients treated with TKI than CT. Multidisciplinary risk assessment including a medication reconciliation by a pharmacist could be crucial to prevent DDI with TKI.

BACKGROUND: Cancer and aging are both frequently associated with malnutrition, a factor of poor prognosis. In adult cancer patients, this may be related in part to impaired energy metabolism, with higher than predicted resting energy expenditure (REE) in about 50% of patients. We hypothesized that frequently impaired energy metabolism in elderly patients could potentiate cancer-associated hypermetabolism, further promoting risk of malnutrition. OBJECTIVE: To study the hypermetabolic response to cancer in a predominantly aged population and the potential underlying determinants. METHODS: This was a cross-sectional exploratory study in patients with non-small-cell lung cancer. REE was measured by indirect calorimetry. Body composition was determined from a single CT scan imaging at L3 level. Endocrine, inflammatory, nutritional and metabolic status were evaluated. RESULTS: Twenty-seven patients, of median age 68 years (range 32-81) completed the study. In this population, mean measured REE was 7.5% higher than calculated REE. Sex and weight accounted for about 51% of REE variations, whereas age accounted only for 4%. However, these parameters did not explain the REE-to-lean body mass (LBM) ratio variations, suggesting that they influenced REE only through their effect on LBM. Among the other parameters evaluated, only the thyroid-stimulating hormone and interleukin-6 plasma levels appeared to have an influence on REE. The study of the consequences of this increase in REE-to-LBM ratio showed a growing inability of patients to meet their energy needs but showed no effect on nutritional markers such as transthyretin. CONCLUSIONS: The results of this pilot study suggest that in our population, age was not an important factor of REE. The elevated energy metabolism was associated with patients' failure to increase their energy intakes sufficiently, which can contribute to the development of cachexia. CLINICAL TRIAL: This trial is registered at clinicaltrials.gov under NCT0314.

BACKGROUND & AIMS: Alterations of nutritional and performance status (PS) are associated with higher risk of chemotherapy toxicity. Increased resting energy expenditure (REE) is frequent in cancer patients and may contribute to cachexia. We investigated whether abnormal energetic metabolism could predict early acute limiting toxicities (ELT) of anticancer treatments. METHODS: In this observational monocentric study, REE was measured by indirect calorimetry before treatment initiation. Based on the ratio of measured REE to REE predicted by the Harris-Benedict formula, patients were classified as hypometabolic (<90%), normometabolic (90-110%) or hypermetabolic (>110%). Body mass index, weight loss, PS, albumin, transthyretin, C-reactive protein (CRP) and muscle mass (CT-scan) were studied. Were defined as ELT any unplanned hospitalization or any adverse event leading to dose reduction or discontinuation during the first cycle of treatment. RESULTS: We enrolled 277 patients: 76% had metastatic disease; 89% received chemotherapy and 11% targeted therapy; 29% were normometabolic, 51% hypermetabolic and 20% hypometabolic. Fifty-nine patients (21%) experienced an ELT. Toxicity was associated with abnormal metabolism (vs normal: OR = 2.37 [1.13-4.94], p = 0.023), PS (2-3 vs 0-1: OR = 2.04 [1.12-3.74], p = 0.023), albumin (<35 vs ≥35 g/l: OR = 2.39 [1.03-5.54], p = 0.048), and inflammation (CRP ≥10 vs <10 mg/l: OR = 2.43 [1.35-4.38], p = 0.004). To predict toxicity, the most sensitive parameter was the REE (83%) followed by PINI (63%), GPS (59%), CRP (55%), PS (41%), NRI (37%), and albumin (16%). In multivariate analysis, elevated CRP was an independent predictor of toxicity (p = 0.047). CONCLUSION: Abnormal basal energy metabolism identifies patients at higher risk of treatment-related acute complications.

Malnutrition is common in oncology. However, it is often detected too late and nutritional support is sub-optimal. The patient's opinion, although often sought in therapeutic decisions in oncology, does not appear to be frequently taken into account in dietetic management. In NutriCancer2012 study, we interviewed patients, relatives and doctors about their perceptions of the impact of malnutrition and its quality of care. Of the 2209 patients questioned, majority said they were concerned about nutrition with 75% considering it essential to take appropriate nutritional care but only 19% self-reported link between malnutrition and fatigue. Physicians underestimated impact of malnutrition on patient's "quality of life". Doctors referred to the lack of human resources and knowledge in nutrition, and more than 80% wished the creation of nutrition teams. Sensitization of the general public and patients (and relatives) as soon as the cancer diagnosis could lead to better malnutrition's screening. Better nutrition training for physicians and creation of nutrition team could optimize management and improve efficacy during cancer treatments.

Angiogenesis inhibition is a major antitumor strategy that has emerged during the last decade. Oral tyrosine kinase inhibitors (TKI) targeting the VEGF receptor, including sunitinib, sorafenib, axitinib, regorafenib, pazopanib, and vandetanib reduce tumor growth and metastasis. These agents are approved for the treatment of metastatic diseases in first or second-line. They display a narrow therapeutic index. However, data in the elderly and/or in patients with multiple illnesses remain scarce. This population is classically excluded from clinical trials. The aim of this review is to provide an overview of existing literature regarding antiangiogenic TKI tolerance in the elderly (>70 years old). We also highlight key points of the pre-therapeutic evaluation and summarize the management of common toxicities.

Chemotherapy-induced peripheral neurotoxicity (CIPN) is a common, potentially severe and dose-limiting adverse effect; however, it is poorly investigated at an early stage due to the lack of a simple assessment tool. As sweat glands are innervated by small autonomic C-fibers, sudomotor function testing has been suggested for early screening of peripheral neuropathy. This study aimed to evaluate Sudoscan, a non-invasive and quantitative method to assess sudomotor function, in the detection and follow-up of CIPN. Eighty-eight patients receiving at least two infusions of Oxaliplatin only (45.4%), Paclitaxel only (14.8%), another drug only (28.4%) or two drugs (11.4%) were enrolled in the study. At each chemotherapy infusion the accumulated dose of chemotherapy was calculated and the Total Neuropathy Score clinical version (TNSc) was carried out. Small fiber neuropathy was assessed using Sudoscan (a 3-min test). The device measures the Electrochemical Skin Conductance (ESC) of the hands and feet expressed in microSiemens (µS). For patients receiving Oxaliplatin mean hands ESC changed from 73 ± 2 to 63 ± 2 and feet ESC from 77 ± 2 to 66 ± 3 µS (p < 0.001) while TNSc changed from 2.9 ± 0.5 to 4.3 ± 0.4. Similar results were observed in patients receiving Paclitaxel or another neurotoxic chemotherapy. During the follow-up, ESC values of both hands and feet with a corresponding TNSc < 2 were 70 ± 2 and 73 ± 2 µS respectively while they were 59 ± 1.4 and 64 ± 1.5 µS with a corresponding TNSc ≥ 6 (p < 0.0001 and p = 0.0003 respectively). This preliminary study suggests that small fiber neuropathy could be screened and followed using Sudoscan in patients receiving chemotherapy.

PURPOSE: Pegylated liposomal doxorubicin (PLD) is widely used in relapsing ovarian carcinoma. Its original formulation is metabolized by the monocyte-macrophage system. One of its main toxicities is the palmoplantar erythrodysesthesia (PPE) syndrome. To date, no predictive factors of PPE have been identified. METHODS: Data of patients (pts) treated with PLD between 2005 and 2014 were retrospectively collected. A case-control study was performed, comparing main baseline clinical and biological characteristics of pts experiencing PPE and those who did not, after at least three cycles of PLD. A pilot analysis of blood monocyte subpopulations (classical, intermediate and non-classical) was performed by FACS in selected pts. RESULTS: Among 88 pts treated with PLD, 28 experienced PPE of any grade (31, 95 % CI 21-41). The first occurrence of PPE was at first cycle in only 11 % of pts, peaked at cycle 2 (32 %) and represented 57 % of cases after cycle 3. Baseline characteristics of pts with PPE were compared to 27 control pts who received at least 3 cycles. Older pts represented 61 % of pts with PPE and 15 % of pts without PPE (p = 0.04 by Chi-square test). Monocyte count and inflammatory parameters were not associated with PPE. However, the analysis of monocyte subpopulations revealed a large inter-patient variability. CONCLUSION: Contrary to most acute toxicities, PPE occurred more frequently after several cycles, suggesting a PLD body accumulation through repeated cycles. PPE was more frequent in pts older than 70 years. Monocyte subpopulations may have different roles on PLD metabolism and warrant further studies.

INTRODUCTION: Sorafenib is a multi-tyrosine kinase inhibitor (TKI). Considerable clinical experience has been accumulated since its first Phase III clinical trial in metastatic renal cancer patients in 2007. The management of its early acute toxicity in fit patients is well known. The management of prolonged treatment becomes the new challenge. AREAS COVERED: Using sorafenib as a key word for PubMed search, we review preclinical and clinical data and discuss the pharmacokinetics and pharmacodynamics of sorafenib, its acute and cumulative toxicities and their consequences for patient management. EXPERT OPINION: The systematic multi-disciplinary risk assessment of cancer patients prior to TKI initiation reduces the risks of acute and late toxicity, especially drug-drug interactions and arterial risks. Sarcopenia is now identified as a major risk of severe toxicity. The very diverse clinical pictures of cumulative toxicity must be known. The monitoring of sorafenib systemic exposure is helpful especially in elderly patients. Moreover, at disease progression, it allows distinguishing between underexposure to sorafenib and truly acquired resistance to the drug. The optimal use of sorafenib should allow improving the reported results of flat-dose. Finally, most of this knowledge could be used for the development and optimal use of the other TKIs.

PURPOSE: Ambulatory chemotherapy is patient friendly but may result in toxicity-induced unscheduled hospitalizations (TIUHs). This emerging issue may increase health care costs. We studied the cost effectiveness of a hospital-home monitoring program based on systematic iterative telephone calls after chemotherapy. PATIENTS AND METHODS: We retrospectively evaluated the rates of chemotherapy-induced unscheduled hospitalizations in patients who were treated in August 2008. Patients were contacted by telephone 1 day before chemotherapy and on the second and eighth days after undergoing chemotherapy. Costs associated with TIUHs were calculated and compared with those of a cohort concomitantly treated using the standard follow-up procedure. RESULTS: A total of 259 patients entered the hospital-home monitoring program. They were compared with 86 patients who had similar characteristics but underwent the standard treatment and follow-up procedure. Inclusion in the hospital-home monitoring program resulted in patients experiencing TIUHs approximately half as frequently as patients in the other group (2.4% v 4.9%; P < .01). Patients in the program experienced TIUHs for a median length of stay of 4 days, representing a nonsignificant reduction in duration of hospitalization (P not significant). Consequently, through a two-fold reduction in TIUH annual incidence, this program represents a reduction in unscheduled hospitalizations per year of 383 days, decreasing hospital costs by 201.468 ($292,468) per year. CONCLUSION: The hospital-home monitoring program is a cost-effective strategy for offering ambulatory chemotherapy treatment to patients with cancer. This program has become our standard procedure for ambulatory chemotherapy in patients with cancer.
