Epidemiology and characteristics of febrile neutropenia in oncology patients from Spanish tertiary care hospitals: PINNACLE study.

Febrile neutropenia (FN) is one of the most common adverse events associated with myelosuppressive chemotherapy for cancer treatment. The objective of this study was to describe the incidence of hospitalization due to FN in Spanish tertiary care hospitals (PINNACLE study). This epidemiological, retrospective, multicenter, nationwide study involved 119 patients from oncology units of 10 Spanish tertiary care hospitals who were admitted for FN. The primary endpoint was to assess the epidemiology and characteristics of FN. The incidence of admissions due to FN in oncology patients was 2.0% (interquartile range [IQR], 1.6-3.0). In terms of fever and absolute neutrophil count (ANC), 37.0% of the patients had a temperature of ≥38.2°C and an ANC of ≤500/m3. The number of patients who received prophylactic treatment with granulocyte colony-stimulating factor (G-CSF) was significantly higher in the palliative group (32.6%) compared with that in the non-palliative group (13.5%). The hospital length of stay was significantly shorter in patients who received prophylactic G-CSF compared with those who did not (5.0 days; IQR, 4.0-9.0 vs. 7.0 days; IQR, 5.0-11.0, respectively). The hospital length of stay was also significantly shorter in patients receiving palliative treatment (5.0 days; IQR, 3.0-7.0) compared with those receiving non-palliative therapy (7.0 days; IQR, 5.0-12.0). In conclusion, the incidence of admissions due to FN in oncology patients was 2.0% and the duration of hospital stay was 7.0 days. Prophylactic G-CSF treatment was found to be associated with better outcomes and shorter hospital stays. Therefore, the use of this treatment becomes relevant for achieving better clinical outcomes and reducing hospitalization cost in the management of FN.

Spanish Society of Medical Oncology consensus on the use of erythropoietic stimulating agents in anaemic cancer patients.

Treatment of anaemia is a very important aspect in the management of cancer patients. In order to carry out a consensus process about the use of erythropoietic stimulating agents (ESAs) in cancer patients, the Spanish Society of Medical Oncology (SEOM) elaborated a working group which coordinated a panel of medical oncology specialists. This working group has reviewed the main issues about the use of ESAs. In addition a consensus meeting was held in Madrid on 25 April 2007. The following conclusions were made: Since ESA treatment increases the haemoglobin (Hb) level and decreases the red blood cell (RBC) transfusion requirements, ESAs should be used within the approved indications in patients undergoing chemotherapy treatment, beginning at a Hb level below 11 g/dl and maintaining it around 12 g/dl, with iron supplements if necessary. Neither increasing the ESA dose in nonresponders nor the use of ESAs in the treatment of chronic cancer-related anaemia is recommended.

Angiogenesis inhibitors in the treatment of non-small-cell lung cancer (NSCLC).

Lung cancer is a leading cause of death worldwide and, although some progress has been made in its treatment, the results remain poor. Better knowledge in tumour biology has allowed us to design anti-target drugs and incorporate them in the treatment of non-small-cell lung cancer (NSCLC). One of the most widely used targeted approaches in this type of tumour has been the inhibition of angiogenesis. Several strategies blocking the VEGF pathway, either at the ligand or recepor level, have been studied and developed. In this review, we present an up-to-date analysis of the current inhibitors of angiogenesis in the treatment of NSCLC.

Clinical practice guidelines on antiemetics in oncology.

The tolerability of chemotherapy has been significantly improved by the advent of effective drugs and protocols for the amelioration of chemotherapy-induced nausea and vomiting. Variables such as the timing of nausea and vomiting (acute, delayed or anticipatory) and the emetogenicity of the chemotherapy must be taken into account in developing guidelines for antiemetic prophylaxis and treatment. Although there are a number of 5-hydroxytryptamine antagonists available, the clinical differences between them are small. The use of drugs with a different mechanism of action, such as the recently introduced neurokinin-1 receptor antagonist aprepitant, may be a useful adjunct to 5-hydroxytryptamine-3 receptor antagonists or steroid prophylaxis. The addition of aprepitant to standard antiemetic regimens increases the proportion of complete responses to antiemetic therapy. For the use of highly emetogenic chemotherapy in oncology a combination of 5-hydroxytryptamine-3 receptor antagonist, dexamethasone and aprepitant is recommended in the acute phase, and dexamethasone plus aprepitant during the subsequent days (many patients do not have their symptoms controlled by 5-hydroxytryptamine-3 receptor antagonist and steroid alone). In either case, lorazepam can be added as required. For moderately emetogenic chemotherapy, a regimen of 5-hydroxytryptamine, dexamethasone and aprepitant is recommended in the acute phase, followed by aprepitant alone in the delayed phase. Alternatively, a 5-hydroxytryptamine-3 receptor antagonist and dexamethasone can be used in the acute phase, followed by dexamethasone for prophylaxis in the delayed phase. For chemotherapy with a low emetogenicity, either dexamethasone, metoclopramide, prochlorperazine or triethyperazine alone is recommended. No prophylaxis is generally required during the delayed phase and indeed may not be necessary during the acute phase either.
