Appropriate management of cutaneous adverse events maximizes compliance with sorafenib treatment: a single-center experience.

AIMS: This report describes a positive experience of adverse event (AE) management of a multidisciplinary clinical team and 18 patients with late-stage renal cell carcinoma and hepatocellular carcinoma attending the Day Hospital Unit of the 'Centro Catanese di Oncologia Humanitas' (Italy) over a 2-year period. METHODS: The management strategy was based on preventive measures for reducing the development of cutaneous AEs, including pain, risk of infection and patient discomfort, while avoiding the discontinuation or the reduction of the sorafenib dosage. RESULTS: As of July 2011, eight patients were still under treatment with sorafenib; seven patients experienced cutaneous AEs and two reported severe cutaneous AEs. CONCLUSION: Our treatment approach seemed to reduce the incidence and/or severity of AEs, keeping patients in treatment, which is essential for good treatment outcomes.

Increased overall survival independent of RECIST response in metastatic breast cancer patients continuing trastuzumab treatment: evidence from a retrospective study.

Recent studies have reported the potential clinical utility for metastatic breast cancer (MBC) patients of continuing trastuzumab beyond progression. Based on those results, here the authors have examined the benefits of trastuzumab-continuation by specifically evaluating RECIST responses upon first line trastuzumab-treatment as a potential predictive marker for therapeutic effect of trastuzumab-continuation beyond metastatic disease progression. The authors carried out a retrospective analysis of 272 HER2 positive MBC patients under trastuzumab treatment at 22 different oncology Italian centers during the years of 2000 and 2001 who progressed under first line trastuzumab-treatment. The primary end point of the study was the survival from the date of first documented progression upon first line trastuzumab treatment of disease. Data analysis involved the use of matching on propensity score to balance variables between treated and untreated subjects and to reduce bias. Of the 272 HER2-positive MBC patients, 154 (56.6%) continued treatment. 79 (51.3%) of those 154 patients showed responses based on RECIST criteria during first-line trastuzumab-treatment. Of the 118 patients that suspended trastuzumab, RECIST responses had been observed in 44 (37.3%). Cox proportional hazards analysis of progressed patients, matched using propensity score, showed that discontinuation of trastuzumab at metastatic disease progression was a risk factor for significantly reduced overall survival in both responder (HR = 2.23; 95% CI = 1.03-4.82) and non-responder groups (HR = 3.53, 95% CI = 1.73-7.21), with no significant differences in the two estimated HRs (P-value of the likelihood-ratio test = 0.690). Continued trastuzumab treatment after disease progression has clinically and statistically significant effects in both RECIST responder and non-responder MBC patients.
