P3.03-044 - Is Toxicity Increased by Adding Intraoperative Chemotherapy to Preoperative Induction Chemotherapy for Mesothelioma Patients? (ID 5945)
14:30 - 14:30 | Author(s): C. Bommeli
- Abstract
Background:
Intracavitary application of chemotherapy after mesothelioma resection is intended to prevent local recurrence. In the present study, we compared hematological and renal toxicity of patients treated with or without additional intracavitary cisplatin-fibrin after (extended) pleurectomy/decortication ((e)P/D) and previous i.v. induction chemotherapy with cisplatin/pemetrexed (CTX).
Methods:
Hemoglobin values, platelet count as well as urea, creatinine, sodium, potassium and magnesium values of 32 patients treated with (e)P/D were compared to the first five patients receiving 44mg/m[2] BSA intracavitary cisplatin-fibrin in our INFLuenCe-Meso phase II trial (www.clinicaltrial.gov NCT01644994). The median time between last cycle of CTX and surgery was 6 weeks (1-14 weeks). The blood values were measured on postoperative day (POD) 1 to 5, 7, 10 and 14 if available. For statistical comparison Mann-Whitney U test was used.
Results:
No significant difference between the 2 groups was observed in the preoperative baseline blood samples. On POD3 hemoglobin dropped significantly more in patients with cisplatin-fibrin application (Figure 1A). However, the use of blood transfusion was not significantly different in both groups. Also sodium, potassium (Figure 1B) and magnesium levels were significantly lower in the study patient group. Disorders in electrolytes were however never reflected in clinical symptoms and reached only in 3 patients a CTCAE level ≥3. There was no significant difference in platelet count, urea and creatinine levels. Figure 1
Conclusion:
The present analysis shows that additional intracavitary cisplatin-fibrin after eP/D and previous i.v. induction chemotherapy with cisplatin/pemetrexed can lead to electrolyte disorders and drop in hemoglobin concentration. However, none of the mentioned laboratory findings had a clinically significant impact on the patients’ postoperative course.
