Long-Term Follow-Up Result of Benign Phyllodes Tumor of the Breast Diagnosed and Excised by Ultrasound-Guided Vacuum-Assisted Breast Biopsy / 한국유방암학회지

PURPOSE: Percutaneous removal of benign breast tumors using ultrasound-guided vacuum-assisted breast biopsy (VABB) has been recently regarded as a feasible and safe method without serious complications. The aim of this study was to evaluate the efficacy and safety of the VABB in the treatment of benign phyllodes tumors, and to identify whether or not surgical re-excision is necessary for benign phyllodes tumors diagnosed and excised by VABB. METHODS: From January 2003 to December 2011, a total of 6,923 VABB were performed in 5,434 patients. Out of 6,923 lesions, 53 were benign phyllodes tumors. Among these, 31 lesions, with a follow-up period of longer than 24 months, were enrolled in this study. Ultrasonography follow-up was performed at 3 to 6 month intervals in order to assess recurrence. The mean follow-up period was 75.9+/-13.5 months (range, 24-94 months). RESULTS: The mean patient age at presentation was 31.6+/-9.4 years. The mean size of the lesion was 1.60+/-0.88 cm. The majority of lesions, 74.2% (23 cases), were palpable, and 25.8% (8 cases) were non-palpable. Twenty-two lesions (71.0%) were classified as Breast Imaging Reporting and Data System category 3, and nine lesions (29.0%) were classified as category 4a, by ultrasonography. During the follow-up period, local recurrence developed in one lesion, making the local recurrence rate 3.2%. CONCLUSION: If a benign phyllodes tumor is diagnosed, and sufficiently excised by VABB, observing the clinical course may be considered as an alternative to performing immediate wide local excision; this is the case despite the fact that it would need to be observed for a prolonged period of time.

Analysis of Outcomes after Curative Resection of Ampullary Carcinoid Tumor

PURPOSE: Ampullary carcinoid tumors are rare and therefore the clinicopathologic characteristics and prognosis after radical surgery have yet to be clarified. The goal of this study was to analyze the outcome of ampullary carcinoid tumors in patients who underwent radical curative resection. METHODS: From January 1998 to December 2005, 10 patients (3.4%) were diagnosed with an ampullary carcinoid tumor among 294 patients who underwent pancreatoduodenectomy for various ampullary neoplasms. The clinical findings from these 10 patients were retrospectively analyzed. RESULTS: The mean patient age was 58.0 +/- 13.4 years and seven were male. A standard pancreatoduodenectomy was performed in three patients and pylorus-preserving pancreatoduodenectomy in seven. An R0 resection was achieved in all 10 patients. The mean tumor size was 2.1 +/- 1.3 cm. Synaptophysin staining was positive in 10 and chromogranin staining was positive in eight patients. The overall and disease-free survival rates were 90% and 80% at 1 year and 64% and 56% at 3 years, respectively. Univariate analyses revealed that a maximum tumor diameter > or = 2 cm and tumor invasion beyond the ampulla were significant risk factors for tumor recurrence. CONCLUSIONS: The results of this study showed that performing a radical resection is the treatment of choice, with the intention of total tumor removal and the possibility of cure.
