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.
"In the case reported here, the lesion observed on the CT images was interpreted as a suspected malignant lesion after we performed laboratory tests, non-invasive transabdominal ultrasound, and DSA. Laparoscopic hepatectomy without the Pringle maneuver and hepatic inflow occlusion was performed to avoid a false negative and possible implantation metastasis due to needle-core biopsy . The lesion was small, adjacent to the inferior surface of the liver, and located by intraoperative ultrasonography. "
[Show abstract][Hide abstract] ABSTRACT: Hepatic pseudolesions detected by helical computed tomography (CT) are not rare, but it is difficult to make a final diagnosis when the hepatic lesion is complicated by the presence of greatly elevated alpha fetoprotein (AFP). Clinical treatment of non-typical hepatic pseudolesions complicated by greatly elevated AFP should confirm the diagnosis and minimize trauma.
Non-invasive procedures including ultrasonography, CT, and micro-invasive digital subtraction angiography could not safely differentiate this lesion from a malignant focus when it was complicated by greatly elevated AFP. Laparoscopic hepatectomy was performed, and pathological analysis showed chronic hepatitis, nodular regenerative hyperplasia, focal nodular hyperplasia of the liver, and mild vascular malformation. The tissue was HbsAg(-) , HbcAg(-), and AFP(+).
Heightened awareness of hepatic pseudolesion complicated by primarily elevated AFP will help physicians avoid unnecessary invasive procedures. Hepatic biopsy is inevitable because of greatly elevated AFP. For suspected hepatic pseudolesion with elevated AFP, needle-core biopsy and follow-up surveillance instead of hepatectomy are recommended to find the source of AFP and make a final diagnosis of pseudolesion.

[Show abstract][Hide abstract] 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.
