Sentinel lymph node biopsy performed with local anesthesia in patients with early-stage breast carcinoma 总被引:2,自引:0,他引:2
Luini A Gatti G Frasson A Naninato P Magalotti C Arnone P Viale G Pruneri G Galimberti V De Cicco C Veronesi U 《Archives of surgery (Chicago, Ill. : 1960)》2002,137(10):1157-1160
HYPOTHESIS: Sentinel lymph node (SN) biopsy performed with local anesthesia has a positive effect on patients' quality of life and on treatment management for early-stage breast carcinoma. This method represents an interesting development in breast-conserving surgery. DESIGN: We performed SN biopsy with local anesthesia in selected patients to test the feasibility of the technique and its impact on our organization and on patients' quality of life. PATIENTS AND METHODS: From September 2000 to December 2001, we studied 115 patients with a palpable breast tumor (maximum diameter, 2.5 cm). The axilla was clinically negative for metastasis in all cases. RESULTS: Forty-eight patients (41.7%) had SNs that were positive for metastasis. In 20 cases (17.4%), the SN was macrometastatic and in 28 cases (24.3%), it was micrometastatic (diameter <2 mm). The SN was negative for metastasis in 66 cases (57.4%). In 1 case, the histologic examination revealed the presence of a non-Hodgkin B-cell lymphoma. The complete axillary dissection performed in the subgroup of patients with macrometastatic SNs showed that in 9 cases (45%), the SN was the only positive node. In another 9 cases (45%), patients had fewer than 4 positive axillary lymph nodes; more than 4 axillary nodes were metastatic in 2 cases (10%). Among the 28 patients with SN micrometastasis, 21 received complete axillary dissection: 15 patients (53.6%) had no other metastasis to the axillary nodes and 6 patients (21.4%) had cancer cells in other axillary nodes. In case of micrometastasis, we suggested that patients enter the International Breast Cancer Study Group 2301 trial (15 of them accepted and signed the informed consent), which compared completion of axillary dissection with no further surgical treatment of the axilla. Based on randomization, 7 patients (25%) in the group with micrometastasis to the SN received no axillary dissection. Patients' tolerance to this kind of treatment was excellent. CONCLUSION: Our experience indicates that SN biopsy performed with local anesthesia can be a suitable alternative to standard intraoperative evaluation with general anesthesia in patients with unifocal, early-stage breast carcinoma. 相似文献

Surgical margins in patients with early-stage breast cancer treated with breast conservation therapy 总被引:20,自引:0,他引:20
Singletary SE 《American journal of surgery》2002,184(5):383-393
BACKGROUND: Patients receiving breast conservation therapy have a lifelong risk of local recurrence. To minimize this risk, surgeons have explored various approaches to examining the surgical margins of the resection specimen. If tumor cells are found at the margin, there is a high probability that residual tumor remains in the surgical cavity. This review examines published reports about standard and innovative approaches to assessing surgical margins, the clinical significance of margin size, and risk factors for positive margins. METHODS: Published literature abstracted in Medline was reviewed using the Gateway site from the National Library of Medicine. CONCLUSIONS: It is still not clear whether obtaining a radical margin will decrease the rate of local recurrence after breast conserving surgery. What is clear is that it is absolutely unacceptable to have tumor cells directly at the cut edge of the excised specimen, regardless of the type of post-surgical adjuvant therapy. 相似文献

Mapping sentinel nodes in patients with early-stage gastric carcinoma 总被引:24,自引:0,他引:24

BACKGROUND: Nodal status in gastric carcinoma is related not only to prognosis but also to the extent of nodal dissection. However, a method for accurate assessment of nodal status during operation has not been established. This study aimed to map the sentinel nodes of gastric carcinoma and to estimate the clinical usefulness of sentinel node biopsy. METHODS: Following laparotomy, a vital dye (0.2 ml 2 per cent patent blue) was injected through a gastroscope into the submucosal layer at four sites around a clinical T1 gastric carcinoma. The dye immediately appeared at the serosal surface and stained lymphatic vessels and nodes. The stained nodes were removed and examined by frozen sectioning. RESULTS: The assay was successful in mapping the lymphatic basins in 203 (96.2 per cent) of 211 patients. The dye stained one or more metastatic nodes in 31 patients, but failed to indicate a metastatic node in four patients with a large involved node. Meticulous postoperative examination of all resected nodes in the standard paraffin slices revealed no new metastases. The accuracy of the assay was 98.0 per cent. CONCLUSION: The method was accurate in predicting nodal status in patients with early-stage gastric carcinoma. 相似文献

INTRODUCTION: There is considerable controversy regarding the value of axillary lymph-node dissection in the adjuvant systemic therapy of patients with early-stage breast cancer. Our objective was to assess the impact of nodal status in assigning adjuvant chemotherapy to these patients. METHODS: We carried out a review of all patients with stage I or II breast cancer treated at 3 university-affiliated hospitals in Saskatoon between Jan. 1, 1998, and Dec. 31, 2000. Data collected included: patient age, sex, tumour size, hormone receptor status, nuclear grade and presence of lymphovascular invasion. Patients were categorized as being at low, high or intermediate risk for recurrence based on Canadian consensus guidelines and at low or high risk according to criteria established by the United States National Institutes of Health (NIH). The influence of nodal status on subsequent treatment was determined assuming that all patients younger than 70 years at high risk of recurrence would receive chemotherapy. RESULTS: We identified 327 women with stage I or II breast cancer in whom all prognostic factors were available for analysis. Applying the Canadian criteria to determine the need for adjuvant chemotherapy, 68% of women would receive chemotherapy regardless of lymph-node status. Applying the NIH criteria, 82.5% of women younger than 70 years would receive adjuvant chemotherapy regardless of nodal status. CONCLUSIONS: Nodal status has little influence on subsequent management. Adoption of a selective approach to axillary lymph-node dissection could avoid the potential morbidities of this procedure in many patients with early-stage breast cancer. 相似文献

Breast-conservation therapy in early-stage breast cancer patients with a positive family history 总被引:4,自引:0,他引:4
Vlastos G Mirza NQ Meric F Hunt KK Mirza AN Newman LA Ames FC Kuerer HM Ross MI Feig B Babiera G Buchholz TA Hortobagyi GN Singletary SE 《Annals of surgical oncology》2002,9(9):912-919
Background Our goal was to evaluate the role of breast-conservation therapy in early-stage breast cancer patients with a family history
(FH) of breast cancer.
Methods Between 1970 and 1994, 1324 female patients with breast cancer were treated with breast-conservation therapy at our institution.
From these, we identified 985 patients with stage 0–II breast cancer and who had available information on FH status. FH was
considered positive in any patient who had a relative who had been previously diagnosed with breast cancer. Disease-specific
survival was calculated from the date of initial diagnosis using the Kaplan-Meier method.
Results The stage distribution for the 985 patients was as follows: 0 in 65 (7%), I in 500 (51%), and II in 420 (43%). The median
age was 50 years (range, 21–88), with a median follow-up time of 8.8 years (range, .25–29). The median tumor size was 1.5
cm. FH was positive in 31%. There were no significant differences in locoregional recurrence, distant recurrence, disease-specific
survival, or incidence of contralateral breast cancer in patients with a positive FH versus patients with a negative FH.
Conclusions Breast-conservation therapy is not contraindicated in early-stage breast cancer patients with a positive FH. 相似文献

BACKGROUND: Laparoscopy-assisted approaches have become popular for dissecting early-stage gastric cancer in Japan, but the outcomes after 5 years of followup have not been reported. STUDY DESIGN: Between January 1998 and March 2002, 94 patients with histologically proved early-stage gastric carcinoma participated in clinical studies and underwent gastrectomy with regional lymphadenectomy to evaluate feasibility and safety of the laparoscopy-assisted approach. Outcomes and pattern of disease failure during followup up to 5 years were evaluated in all patients. Multivariable analysis was performed to identify relevant prognostic factors. RESULTS: Conversion to open procedures occurred in three patients. Median blood loss was 90 mL (interquartile range, 160 mL), and duration of operation was 230 minutes (interquartile range, 60 minutes). Operative morbidity and mortality were 22.3% and 0%, respectively. Nine patients died during the course of followup, for an overall 5-year survival rate of 90%. Two patients died of recurrent disease, and 2 other patients have been diagnosed with recurrences, for a 5-year recurrence-free survival of 95.6%. Three patients with recurrent cancer, including 1 with port-site recurrence, had stage IA disease (pT1pN0) at operation. Diabetes mellitus as a comorbidity was prominent as a prognostic factor. CONCLUSIONS: Outcomes of patients with a preoperative diagnosis of early-stage cancer were excellent when treated with a laparoscopy-assisted approach, although rare patterns of disease failure were observed. 相似文献
