Hydroelectrolytic disorders are one of the most common metabolic complications in cancer patients. Although often metabolic alterations affecting various ions are part of the manifestations of the oncological disease, even in the form of paraneoplastic syndrome, we must not forget that very often, these disorders could be caused by various drugs, including some of the antineoplastic agents most frequently used, such as platin derivatives or some biologics. These guidelines review major management of diagnosis, evaluation and treatment of the most common alterations of sodium, calcium, magnesium and potassium in cancer patients. Aside from life-sustaining treatments, we have reviewed the role of specific drug treatments aimed at correcting some of these disorders, such as intravenous bisphosphonates for hypercalcemia or V2 receptor antagonists in the management of syndrome of inappropriate antidiuretic hormone secretion-related hyponatremia. © 2014, The Author(s).

Background Stem cell-based therapy has emerged as a potential therapy in acute myocardial infarction (AMI). Although various approaches have been studied, intracoronary injection of bone marrow autologous mononuclear cells (BMMC) and the ability of granulocyte colony-stimulating factor (G-CSF) to mobilize endogenous cells have attracted the most attention. Objectives This study compares, for the first time, the efficacy of BMMC injection, G-CSF mobilization, and the combination of both with standard treatment. Methods On Day 1 after primary percutaneous coronary intervention, 120 patients were randomized to a 1) intracoronary BMMC injection; 2) mobilization with G-CSF; 3) both (BMMC injection plus G-CSF); or 4) conventional treatment (control group). G-CSF, 10 μg/kg/day subcutaneously, was started Day 1 and maintained for 5 days. BMMC injection was performed on Days 3 to 5. Our primary endpoint was absolute change in 12-month left ventricular ejection fraction (LVEF) and left ventricular end-systolic volume (LVESV) relative to baseline measured by cardiac magnetic resonance. Results The mean change in LVEF between baseline and follow-up for all patients was 4 ± 6% (p = 0.006). Change in LVEF and LVESV over time did not differ significantly among the 4 groups. Patients actively treated with any stem cell approach showed similar changes in LVEF and LVESV versus control subjects, with a small but significant reduction in infarct area (p = 0.038). Conclusions In our study, 3 different bone marrow-derived stem cell approaches in AMI did not result in improvement of LVEF or volumes compared with standard AMI care (Trial of Hematopoietic Stem Cells in Acute Myocardial Infarction [TECAM]; NCT00984178) © 2015 American College of Cardiology Foundation.

Supportive Care in Cancer

Hyponatremia (Na ˂135 mmol/l) is the most frequent electrolyte disorder in clinical practice, and the syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the commonest cause of hyponatremia in cancer patients. Correcting hyponatremia in these patients can reduce morbidity and mortality, increase the response to anti-cancer agents, and help reduce hospital length of stay and costs. Tolvaptan is an oral medication used to treat SIADH-related hyponatremia patients that needs to be initiated at hospital so patients can have their serum sodium monitored. If tolvaptan could be initiated in hospital day care units (DCUs), performing the same tests, hospitalization could be avoided, quality of life improved, and costs reduced. This is the first publication where a panel of oncologists are sharing their experience and making some recommendations with the use of tolvaptan to treat SIADH-related hyponatremia in DCU after collecting and examining 35 clinical cases with these type of patients. The conclusion from this retrospective observational analysis is that the use of tolvaptan in DCU is safe and effective in the therapeutic management of SIADH-related hyponatremia. © 2015, The Author(s).

BACKGROUND: Intermittent claudication (IC) and its consequences have customarily been underestimated in women. Our study aimed to determine the differences on functional and quality-of-life issues between women and men in a large group of claudicants.METHODS: This study was an observational, cross-sectional, nonrandomized, multicenter study of 1,641 claudicants (406 women). Information was collected from patients' medical history, a physical examination, the ankle-brachial index (ABI), the Walking Impairment Questionnaire (WIQ), and the European Quality of Life Questionnaire (EQ-5D).RESULTS: On average, women with IC were older than men with IC (70.0 vs. 67.8 years; p<0.001) and tended to have a different socio-occupational status. Women were more likely to be obese and less likely to smoke or have dyslipidemia (p<0.001). Women were notable for their greater prevalence of cardiac insufficiency (p=0.016) and arrhythmias (p<0.001) and a lower prevalence of ischemic cardiopathy and acute myocardial infarction (p<0.001). At the same time, there was a significantly higher level of osteoarticular diseases in women: arthrosis (p<0.001), arthritis (p<0.001), and lumbar pathology (p=0.006). All the symptoms evaluated that were associated with IC were more frequent in women (p<0.05). The mean ABI was similar in claudicant women and men. Conversely, the parameter estimates of the WIQ were significantly lower in women (by 4.3%, and 6.5%, respectively; p=0.003). Likewise, the EQ-5D score was 7% lower in women than in men (from 0.52 to 0.59; p<0.001).CONCLUSIONS: Women claudicants have higher risk factors and more frequent cardiovascular comorbidity than men do. Women have a lower capacity for exercise and a poorer quality of life than male claudicants, despite having a similar ABI. These poorer outcomes in women can be partially explained by the presence of greater osteoarticular comorbidity. Source

Proteasome inhibitors (PIs), namely bortezomib, have become a cornerstone therapy for multiple myeloma (MM), potently reducing tumor burden and inhibiting pathologic bone destruction. In clinical trials, carfilzomib, a next generation epoxyketone-based irreversible PI, has exhibited potent anti-myeloma efficacy and decreased side effects compared with bortezomib. Carfilzomib and its orally bioavailable analog oprozomib, effectively decreased MM cell viability following continual or transient treatment mimicking in vivo pharmacokinetics. Interactions between myeloma cells and the bone marrow (BM) microenvironment augment the number and activity of bone-resorbing osteoclasts (OCs) while inhibiting bone-forming osteoblasts (OBs), resulting in increased tumor growth and osteolytic lesions. At clinically relevant concentrations, carfilzomib and oprozomib directly inhibited OC formation and bone resorption in vitro, while enhancing osteogenic differentiation and matrix mineralization. Accordingly, carfilzomib and oprozomib increased trabecular bone volume, decreased bone resorption and enhanced bone formation in non-tumor bearing mice. Finally, in mouse models of disseminated MM, the epoxyketone-based PIs decreased murine 5TGM1 and human RPMI-8226 tumor burden and prevented bone loss. These data demonstrate that, in addition to anti-myeloma properties, carfilzomib and oprozomib effectively shift the bone microenvironment from a catabolic to an anabolic state and, similar to bortezomib, may decrease skeletal complications of MM. © 2013 Macmillan Publishers Limited All rights reserved.
