Adult Soft Tissue Sarcoma Local Recurrence After Adjuvant Treatment Without Resection of Core Needle Biopsy Tract
ABSTRACT BACKGROUND: Core needle biopsies of sarcomas allow a diagnosis in a high percentage of patients with few complications. However, it is unclear whether the tract needs to be excised to prevent recurrences. QUESTIONS/PURPOSES: We therefore determined the rates of recurrence and metastases in patients with Stage III extremity sarcomas, who underwent wide local resection without excision of the needle tract and also received adjuvant treatment. METHODS: We retrospectively reviewed 59 adult patients with deep, larger than 5 cm, high-grade soft tissue sarcomas of the upper or lower extremity treated between January 1999 and April 2009. All the patients underwent a core needle biopsy. Resection was performed with wide margins. The biopsy tract was not resected during the definitive surgery. Fifty-seven patients (97%) received preoperative and/or postoperative radiation, whereas 49 patients (83%) received chemotherapy. Local recurrence and distant recurrence rates were determined. The minimum followup was 24 months (median, 56 months; range, 24-122 months). RESULTS: The local recurrence rate was 9%. Fifteen patients (25%) developed metastasis after diagnosis. Seven of the 59 patients (12%) had microscopic positive margins at resection. CONCLUSIONS: Our data demonstrate no increase in local recurrence rates or rates of metastatic disease compared with previously published studies when resection of the core biopsy tract was not performed. LEVEL OF EVIDENCE: Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

ABSTRACT: Lipomatous tumours are rare in the head and neck region. Their biological behaviour varies greatly, from absolutely benign to histologically benign but locally infiltrative and, finally, invasive with metastatic potential. Each lipomatous tumour has to be treated accordingly. It is of paramount importance before eventual surgery is planned to perform adequate imaging, diagnostic biopsy and careful assessment. Only in small (<5 cm), superficial soft tissue tumours or when magnetic resonance imaging has demonstrated specific features of lipoma, may diagnostic biopsy be omitted. In these cases, expectant management or simple excision is appropriate. Adequate preoperative diagnosis is important to assure adequate tumour control as well as optimal functional and cosmetic outcome. The major problem in the treatment of lipomatous tumours of the head and neck region is the presence of nearby delicate structures. Especially, wide surgical excision of liposarcomas may be hindered by anatomic constraints and may result in impaired functional and cosmetic outcome. Neoadjuvant radiotherapy and specific systemic chemotherapy may be helpful in the treatment of liposarcoma, especially when unresectable or when primary surgery is expected to result in poor oncological, functional or cosmetic outcome. Greater emphasis placed on the underlying biology of individual sarcoma subtypes, development and evaluation of novel therapies and greater specificity in the selection of chemotherapy agents based on activity in individual histological subtypes are expected to lead to improved efficacy of systemic treatment.Archives of Oto-Rhino-Laryngology 05/2014; 272(5).

ABSTRACT: In multimodal therapy concepts for bone sarcomas, tumor resection is a deciding factor. Modern imaging techniques have made preoperative resection planning much easier and precisely allow tumor boundaries to be defined.Der Unfallchirurg 07/2014; 117(7):593-9.
