Evaluation of toxicity: all patients will be evaluable for toxicity from the time of their first treatment with Caelyx and Lapatinib. Evaluation of response: all patients included in the study must be assessed for response to treatment, even if there are major protocol treatment deviations or if they are ineligible. Each patient will be assigned one of the following categories: 1) complete response, 2) partial response, 3) stable disease, 4) progressive disease, 5) early death from malignant disease, 6) early death from toxicity, 7) early death because of other cause, or 9) unknown (not assessable, insufficient data). All of the patients who met the eligibility criteria (with the possible exception of those who received no study medication) should be included in the main analysis of the response rate. Patients in response categories 4-9 should be considered as failing to respond to treatment (PD). Thus, an incorrect treatment schedule or drug administration does not result in exclusion from the analysis of the response rate.
