Background The use of anthracyclines is limited by the occurrence of cardiotoxicity. In an effort to prevent this cardiotoxicity, different anthracycline derivates have been studied. Objectives To determine the occurrence of cardiotoxicity with the use of different anthracycline derivates in cancer patients. Search strategy We searched The Cochrane Central Register of Controlled Trials (CENTRAL), (The Cochrane Library, Issue 2, 2009), MEDLINE (1966 to 29 May 2009) and EMBASE (1980 to 2 June 2009). In addition, we searched reference lists of relevant articles, conference proceedings and ongoing-trials-databases. Selection criteria Randomised controlled trials (RCTs) in which different anthracycline derivates were compared in cancer patients (children and adults). Data collection and analysis Two authors independently performed study selection, assessment of risk of bias and data-extraction including adverse effects. Main results We identified five RCTs of varying quality addressing epirubicin versus doxorubicin (1036 patients) with the same dose. The meta-analysis showed no evidence for a significant difference in the occurrence of clinical heart failure between the treatment groups (RR = 0.36, 95% CI 0.12 to 1.11). However, there is some suggestion of a lower rate of clinical heart failure in patients treated with epirubicin.We identified two RCTs with varying quality addressing liposomal-encapsulated doxorubicin versus conventional doxorubicin (521 patients). The meta-analysis showed a significantly lower rate of both clinical heart failure and clinical and subclinical heart failure combined in patients treated with liposomal-encapsulated doxorubicin (RR = 0.20, 95% CI 0.05 to 0.75 and RR = 0.38, 95% CI 0.24 to 0.59 respectively). It should be noted that in one of the studies patients in the liposomal-encapsulated doxorubicin group received a higher cumulative anthracycline dose than patients in the doxorubicin group.For the other possible combinations of different anthracycline derivates only one RCT (epirubicin versus liposomal-encapsulated doxorubicin) or no RCT was identified. Authors' conclusions We are not able to favour either epirubicin or doxorubicin when given with the same dose. Based on the currently available evidence on heart failure, we conclude that in adults with a solid tumour liposomal-encapsulated doxorubicin should be favoured over doxorubicin. For both epirubicin versus doxorubicin and liposomal-encapsulated doxorubicin versus conventional doxorubicin no conclusions can be made about the effects of treatment in children treated with anthracyclines and also not in patients diagnosed with leukaemia. More research is needed. For other combinations of anthracycline derivates not enough evidence was available to make definitive conclusions about the occurrence of cardiotoxicity in patients treated with anthracyclines.

Different anthracycline derivates for reducing cardiotoxicity in cancer patients

PURPOSE AND METHODSThe European Lung Cancer Working Party (ELCWP) performed a randomized trial with the primary end point to determine if maintenance chemotherapy with 12 courses of etoposide (120 mg/m2 on days 1 and 3) and vindesine (3 mg/m2 on day 3) could improve progression-free survival in small-cell lung cancer (SCLC) patients who responded to six courses of induction chemotherapy with ifosfamide, etoposide, and an anthracycline (doxorubicin or epirubicin).RESULTSAmong 235 eligible patients initially registered, 91 were randomized to receive maintenance therapy, including seven patients who were no longer responding. Among 84 randomized responders, progression-free survival was significantly improved (P = .003) by maintenance therapy, with median durations (maintenance v follow-up) of 25 versus 12 weeks after the second randomization, but survival was not significantly increased (P = .10), with median durations of 48 and 38 weeks. However, in a multi-variate analysis that took into account disease e...

Background: This prospective observational study estimated the effect of prognostic factors, particularly continued smoking during therapy, on survival in advanced non-small cell lung cancer (NSCLC) patients receiving gemcitabine-platinum. Further, prognostic factors were used to build a survival model to improve prognosis prediction in naturalistic clinical settings.

Methods: Eligibility criteria included: Stage IIIB/IV NSCLC, no prior chemotherapy, and Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1. A Cox regression model was constructed and validated by randomizing patients into two datasets (Construction [C]:Validation [V]; 3:1 ratio). Country, disease stage, hypercalcemia, “N” factor, weight reduction, performance status, and superior vena cava obstruction were pre-defined variables forced into the model. Continued smoking was tested with adjustment for these variables.

Results: One thousand two hundred and fourteen patients (C=891 and V=323) were enrolled. The final predictive model, established in the Construction dataset, identified four significant (p≤0.05) and independent predictors of survival, which were disease stage, performance status, gemcitabine-platinum regimen, and T-stage. Smoking during therapy was not significantly associated with survival (Hazard Ratio [95% CI]: 0.955 [0.572, 1.596], p=0.8618; versus never smokers).

Conclusions: Although continued smoking during therapy was not significantly associated with shorter survival, the model developed in this study forms an evidence-based approach to assessing prognosis in advanced stage NSCLC.
