Abstract
Background
Biopsies for diagnosis before chemotherapy is common in children with malignant solid tumors. Wound healing is delayed by chemotherapy; however, the ideal interval between biopsy and chemotherapy remains unknown. We aimed to summarize the relationship between chemotherapy timing and postoperative surgical complications.
Procedure
We retrospectively reviewed patients with malignant solid tumors who underwent chemotherapy after surgical biopsy at our institution between January 2014 and August 2020. The primary outcomes were postoperative surgical complications (within 30 days) and the timing of chemotherapy.
Results
Forty-three patients were analyzed. The types of tumors were neuroblastoma (n = 20), hepatoblastoma (n = 10), Ewing sarcoma (n = 5), germ cell tumor (n = 3), angiosarcoma (n = 1), clear cell sarcoma (n = 1), ganglioneuroblastoma (n = 1), rhabdoid tumor (n = 1), and rhabdomyosarcoma (n = 1). The operative procedures were thoracoscopy (n = 5), laparotomy (n = 17), laparoscopy (n = 14), and superficial (n = 7). The median time [range] to chemotherapy after biopsy was 4 [0–21] days. No surgical complications occurred before chemotherapy, and two (4.7%) patients experienced complications after chemotherapy. These included postoperative hemorrhage (grade 3) and surgical site infection (grade 1). Chemotherapy was initiated 1 and 6 days after biopsy, respectively, in these cases. Complications occurred 10 and 23 days after biopsy, respectively.
Conclusion
The rate of postoperative surgical complications related to biopsy seems acceptable, even when chemotherapy was initiated in the early postoperative period. Early initiation of chemotherapy after biopsy may be a suitable option, particularly in children with bulky or symptomatic malignant solid tumors.
