OBJECTIVES: The feasibility and accuracy of sentinel lymph node biopsy (SLNB) in the treatment of breast cancer is widely acknowledged today. The aim of our study was to compare the hospital-related costs of this strategy with those of conventional axillary lymph node dissection (ALND). METHODS: A retrospective study was carried out to determine the total direct medical costs for each of the two medical strategies. Two patient samples (n = 43 for ALND; n = 48 for SLNB) were selected at random among breast cancer patients at the Centre Leon Bérard, a comprehensive cancer treatment center in Lyon, France. Costs related to ALND carried out after SLNB (either immediately or at a later date) were included in SLNB costs (n = 18 of 48 patients). RESULTS: Total direct medical costs were significantly different in the two groups (median 1965.86 Euro versus 1429.93 Euro, p = 0.0076, Mann-Whitney U-test). The total cost for SLNB decreased even further for patients who underwent SLNB alone (median, 1,301Euro). Despite the high cost of anatomic pathology examinations and nuclear medicine (both favorable to ALND), the difference in direct medical costs for the two strategies was primarily due to the length of hospitalization, which differs significantly depending on the technique used (9-day median for ALND versus 3 days for SLNB, p < 0.0001). CONCLUSIONS: A lower morbidity rate is favorable to the generalization of SLNB, when the patient's clinical state allows for it. From an economic point of view, SLNB also seems to be preferred, particularly because our results confirm those found in two published studies concerning the cost of SLNB. 相似文献

Sentinel lymph node biopsy (SLNB) has been a reliable technique to accurately predict the axilla node status in women with breast cancer with clinically negative lymph nodes. Based on predictive accuracy evidence from large-scale clinical trials, SLNB has become the current standard of care in breast cancer, preventing unnecessary axilla lymph node dissection and its related adverse events in patients who test negative with SLNB. Now a Phase III randomized trial provides evidence that avoiding axilla lymphadenectomy in patients with positive SLNB does not increase locoregional recurrence or mortality. In this article the benefits, risks and selection criteria to safely prevent axilla lymphadenectomy even by positive SLNB are discussed. Moreover, limitations of this practice-changing trial are described with emphasis on caution in patient selection. 相似文献

ObjectivesControversy about quality-of-life (QOL) benefits of sentinel lymph node biopsy (SLNB) versus axillary lymph node dissection (ALND) in patients with breast cancer remains. Our aim was to compare the impact of SLNB and ALND on QOL and arm symptoms of patients with early breast cancer, using generic (short form 36 health survey) and tumor site–specific (FACT-B+4) instruments.MethodsThis was a prospective longitudinal observational study of 93 patients (64 SLNB, 29 ALND). Patients were evaluated presurgery and 1, 6, and 12 months postsurgery. Generalized estimation equation models were constructed to assess the effect of treatment on QOL. The relative risks of edema, dysesthesia, and heaviness were calculated comparing ALND to SLND.ResultsMost patients presented T1 (67.7%) and underwent breast-conserving surgery (92.5%). At 12 months, the SLNB group presented deterioration on the FACT-B+4 Arm Scale (beta coefficient estimated a change of −1.6 score points; P < 0.01) while, compared with SLNB, the deterioration in the ALND group was almost 2 additional score points higher (P = 0.009). FACT-B+4 global summary and short form 36 health survey did not show statistically significant differences between groups. Relative risk of dysesthesia and subjective edema was higher for the ALND group than for the SLNB group (1.97 and 2.11 at month 12; P < 0.01).ConclusionThese results confirm the benefit of SLNB due to its lower arm morbidity impact on QOL, compared with ALND. There are clinically relevant between-treatment differences in the Arm Scale of FACT-B+4, while there were no relevant differences in general well-being, measured with the disease-specific FACT-B+4 and the generic short form 36 health survey. 相似文献

Regional lymph node status is the most important prognostic factor in breast cancer. Sentinel lymph node biopsy is the standard method of axillary staging in early breast cancer patients with clinically negative nodes. Preoperative lymphoscintigraphy might support refining biopsy findings by determining the number and location of sentinel lymph nodes. In aged or overweight patients, in the presence of atypical or extra-axillary lymphatic drainage, non-visualized lymph nodes, or sentinel lymph nodes close to the isotope injection site, detection could be aided by a new, hybrid imaging tool: the single-photon emission computed tomography combined with computed tomography (3D SPECT/CT). For the first time in Hungarian language, authors overview the literature: all 14 English-language articles on the implementation of 3D SPECT/CT in sentinel lymph node detection in breast cancer are included. It is concluded that 3D SPECT/CT increases the success rate and quality of preoperative sentinel node identification, and is capable of providing a more accurate staging of breast cancer patients in routine clinical practice. 相似文献

OBJECTIVE: Breast cancer remains the highest incident cancer among females in the United States and previous research suggests that a considerable portion of patients will eventually progress to the metastatic phase of the disease. This paper provides the first estimate of the lifetime direct costs of treating metastatic disease for one annual diagnostic cohort of breast cancer patients. METHODS: Incidence rates were combined with US population counts to estimate the number of breast cancer cases diagnosed in 1994. Estimates of progression to metastatic disease (from Canadian provincial cancer registry data), costs of care (derived from patients' claims histories), survival (from SEER data), and national mortality rates (from US Census Bureau) were integrated, using Statistics Canada's Population Health Model (POHEM) to calculate lifetime costs. RESULTS: This study estimates that more than 40% of the women diagnosed with breast cancer will progress to metastatic disease. On average, women with metastatic disease are expected to live 3 years and to incur direct treatment costs of approximately dollar 60,000 per case, resulting in a total lifetime cost for the cohort of almost dollar 4.2 billion. CONCLUSIONS: The high rate of recurrence of breast cancer argues for the development of interventions that can prevent or delay the onset of metastatic disease. These estimates of lifetime costs and the methodology on which they are based can be used to evaluate the cost-effectiveness of such secondary prevention strategies. These estimates also can serve as a benchmark against which the lifetime costs of treating other diseases can be assessed. 相似文献

Methods The sentinel lymph node (SLN) of 187 patients were located with preoperative lymphoscintigraph technique with 99mTc-SC and labeled with methylene blue during the operations. The metastasis of SLN was detected using frozen section technique. There were 51 patients whose SLN were positive having been carried with modified radical mastectomy of breast cancer and axillary lymph node dissection (ALND), 136 patients' SLN were negative,58 patients of those were carried with mammectomy or partial mastcctomy and ALND (group A),while 78 patients were carried out with mammectomy or partial mastectomy only (group B). The sentinel lymph nodes were detected with HE stain after surgery. All the patients were treated with chemotherapy,and the patients with partial mastcctomy must be treated with radiotherapy. There were 2 patients with micrometastasis in group B being treated with mammectomy or partial mastcctomy only,and carried out with ALND again. Results The number of cases with upper limb numbness, edema, dysfunction in group A were 36,8 and 45 cases, in group B were 2,0,0 case respectively. Group A compared with group B was increased significantly (P< 0.05). The number of local recurrence within 1, 3 and 5 years were 0,0,2 cases;lymphatic metastasis were 1,5,8 cases; the distant metastasis were 2,8,12 cases; the disease-free survival were 60,57,49 cases. In group B, the number of local recurrence within 1, 3 and 5 years were 0,0,6 cases, lymphatic metastasis were 3,8,12cases,the distant metastasis were 4,8,16 cases,the disease-free survival were 76,70,61 cases. There were not significant differences between the two groups(P> 0.05). Conclusion It is simple and accurate to carry out SLNB using preoperative lymphoscintigraph technique with 99mTc-SC combined with methylene blue,and the effect is reliable. 相似文献

In the treatment of malignant tumors regional lymphadenectomy is used for two purposes. It is used partly for staging the regional lymph nodes which is a significant and independent prognostic factor and determines the need for adjuvant oncologic treatment and partly for achieving locoregional disease control. Removal of tumor-free lymph nodes by regional lymph node clearance is unnecessary according to our current knowledge. Since the sensitivity and specificity of non-invasive clinical examinations are insufficient in predicting the nodal status the histological study of the regional lymph nodes cannot be abandoned. A new and minimally invasive surgical procedure, the mapping and removal of the first tumor draining lymph node, the sentinel node provides the possibility of pathological nodal staging without performing formal lymphadenectomy. Mapping of the sentinel node can be performed by the use of a radioisotope and intraoperative hand-held gamma-probe or a vital blue dye or a combination of these two. This latter method was used by the authors in 73 patients (25 with malignant melanoma and 48 with breast cancer). Sentinel lymph node biopsy was performed successfully in 92% of patients with melanoma and 90% of patients with breast cancer. In three breast cancer patients the sentinel node inaccurately predicted the axillary status as negative, but is was in 93% accurate in predicting the histologic nodal state. According to our preliminary experiences intraoperative gamma-probe guided sentinel lymph node biopsy is considered a feasible procedure in both malignant melanoma and breast cancer. More experiences are needed before introducing this method in the routine clinical practice. 相似文献
