title: Incidence of palmar-plantar erythrodysesthesia in pretreated and unpretreated patients receiving pegylated liposomal doxorubicin.
abstract: OBJECTIVE
  Association between pegylated liposomal doxorubicin-based regimens and palmar-plantar erythrodysesthesia have just been emphasized, whereas the relationship between previous treatment and palmar-plantar erythrodysesthesia is still a matter of discussion. We evaluate the relationship between previous chemotherapy treatments and the development of palmar-plantar erythrodysesthesia in patients receiving pegylated liposomal doxorubicin-based regimens.
  
  
  METHODS
  Between January 2005 and November 2006, 92 patients received regimens including pegylated liposomal doxorubicin. Patients were divided into three groups based on pegylated liposomal doxorubicin dosing interval length, different dose chosen, and previous chemotherapy.
  
  
  RESULTS
  Among pretreated patients receiving regimens including 30 mg/m2 of pegylated liposomal doxorubicin repeated every three weeks, the incidence of palmar-plantar erythrodysesthesia was not significantly higher than in unpretreated patients receiving the same weekly schedule (P = 0.4). There was no difference in the incidence of palmar-plantar erythrodysesthesia between pretreated patients with regimens including 30 mg/m2 of pegylated liposomal doxorubicin every three weeks and pretreated patients receiving 20 mg/m2 of pegylated liposomal doxorubicin every two weeks (P = 0.8). The prevalence of palmar-plantar erythrodysesthesia observed in the unpretreated group exposed to 30 mg/m2 every three weeks was comparable to that of the pretreated group receiving 20 mg/m2 biweekly (P = 0.3). However, excluding all the patients who developed grade 1 palmar-plantar erythrodysesthesia, the incidence of grade 2 and 3 palmar-plantar erythrodysesthesia observed in pretreated patients receiving regimens including 20 mg/m2 of pegylated liposomal doxorubicin biweekly was significantly higher than in unpretreated patients receiving 30 mg/m2 of pegylated liposomal doxorubicin every three weeks (P = 0.001).
  
  
  CONCLUSIONS
  Our findings indicate that the pretreatment is not involved in the increased incidence of any grade palmar-plantar erythrodysesthesia. On the contrary, the study could suggest that the type of previous treatment may be an important factor in the development of more severe forms of palmar-plantar erythrodysesthesia.
