Introduction
Patients with a diagnosis of breast ductal carcinoma in situ (DCIS) have a low risk of developing axillary metastases. The use of sentinel node biopsy in this group of patients is controversial. The objective of this study is to determine if the sentinel node biopsy benefits a subgroup of patients with DCIS.Patients and method
Between April 2002 and December 2007, patients with a diagnosis of DCIS and who underwent a sentinel node biopsy were included in the study. In our centre the sentinel node biopsy was performed in patients with DCIS who required a mastectomy, high grade and >2 cm DCIS and palpable DCIS.Results
Forty-seven patients were included in the study. In all cases the sentinel node was identified. Twenty-five (53.1%) patients underwent a mastectomy due to extensive DCIS; 14 of these (56%) with immediate reconstruction with implants. Twenty-five (53.1%) patients had high grade DCIS. In 7 (14.8%) patients the tumour was palpable. Fourteen patients (29.7%) were upgraded to invasive breast cancer in the definitive histology. In 2 (4.2%) patients who underwent a mastectomy a positive sentinel node was found.Conclusions
Performing sentinel node biopsy in this group of DCIS patients has lead us to identify 4% of patients with positive sentinel nodes. Furthermore, 29.7% of the patients have avoided a second invasive diagnostic procedure for definitive histology. For these reasons we consider it appropiate to perform sentinel node biopsy in this subgroup of patients with DCIS of the breast. 相似文献2.

Desmoplastic melanoma (DM) accounts for 0.4% to 4% of all melanomas. These skin tumors are mainly formed by amelanotic spindled melanocytes immersed in an abundant collagen stroma and are classified as pure when the desmoplastic component accounts for at least 90% of the invasive tumor and as mixed or combined otherwise. DMs are more common in men (male to female ratio, 1.7 to 2:1), and the mean age at diagnosis is 66 to 69 years. The tumors tend to occur in chronically sun-exposed areas, often in association with lentigo maligna, and are difficult to recognize because they can resemble a scar, presenting as a firm, unpigmented papule or plaque with poorly defined borders. DMs also have a strong tendency to recur locally, and pure variants rarely spread to the lymph nodes. Nonetheless, recently published series suggest that patients with DM have a similar prognosis to those with nondesmoplastic melanoma of the same thickness. The clinical management of DM varies in certain aspects from that of other melanomas and is reviewed in this article. 相似文献
