OBJECTIVE: The authors' goal was to determine whether cognitive behavioral treatment of residual symptoms of depression might have a significant effect on relapse rate. METHOD: A 6-year follow-up assessment was conducted of 40 patients with primary major depressive disorder who had been successfully treated with antidepressants and were randomly assigned to either cognitive behavioral treatment of residual symptoms or standard clinical management. RESULTS: Ten of the patients (50%) in the cognitive behavioral treatment group and 15 (75%) in the standard clinical management group relapsed. The difference did not attain statistical significance. When multiple relapses were considered, patients in the cognitive behavioral treatment group had a significantly lower number of depressive episodes than those in the standard clinical management group. Patients responded to the same antidepressant drug used in the index episode; in two cases (4%), resistance occurred. CONCLUSIONS: The protective effects of cognitive behavioral treatment that were evident at 4-year follow-up faded afterward. Cognitive behavioral treatment of residual symptoms, however, improved the long-term outcome of major depression in terms of total number of episodes during the follow-up period. 相似文献

The effects of induced parturition on calf mortality rates were studied in 24 winter-calving, pasture-fed, dairy herds in south-western Victoria. Parturition was induced when most cows were between 27 and 35 weeks of pregnancy. Control groups were selected from cows in the same herds in which calving was not induced. The incidence of mortality within 7 days of birth was much higher among calves from cows in induced groups relative to those in control groups (estimated median herd mortality incidence 72% and 7%, respectively). The incidence of calf mortality was high among groups induced at all stages of pregnancy that were investigated. However, differences in calf mortality incidence, relative to controls, were increased among groups induced at earlier stages of pregnancy. 相似文献

Orthodontic bands form retention areas which create favourable conditions for growth of lactobacilli. This study deals with the numbers and specific species of lactobacilli in the oral cavity of teenage orthodontic patients. High numbers of lactobacilli were obtained (log 6.398 +/- 0.761 cfu/ml) and the buffer capacity of saliva indicated a high caries risk amongst these individuals but the actual DMFT values were relatively low. Homofermentative lactobacilli predominated in both plaque and saliva and particularly L. salivarius and L. casei. These two lactobacilli species indicated that these patients are at a high caries risk. Several other homofermentative and heterofermentative lactobacilli were isolated which indicated the complexity of the oral lactobacilli community in saliva and plaque. 相似文献

OBJECTIVES: The sentinel node is defined as the first-line axillary lymphatic drainage node in breast cancer. If the sentinel node can be identified, during axillary dissection for breast cancer, resection could be limited reducing subsequent morbidity. However, before modifying the standard dissection procedure, it is important to prove that the sentinel node is representative of the metastatic status of other axillary nodes. PATIENTS AND METHODS: Between March and December 1996, 86 patients (mean age 58 years, range 32-82) underwent amputation (n = 20), tumorectomy with dissection (n = 56) or tumorectomy followed by secondary dissection (n = 10) for breast cancer. Ten ml of diluted patent blue was injected either into the peripheral portion of the tumor or the tumorectomy cavity. Node dissection was performed 10 to 20 minutes after injection. The blue sentinel node was identified prior to standard dissection. RESULTS: A mean 12 nodes were removed (range 4-21). Seventy-nine sentinel nodes were identified (91%) and in 7 cases (8%) a sentinel node could not be identified. In 7 other cases the sentinel node was a false negative, i.e. non malignant despite metastases in other dissected nodes. In all the other cases, the status of the sentinel node predicted the status of the other nodes, i.e. a non-metastatic sentinel node associated with other metastatic nodes. Finally, in 7 cases, the sentinel node was the only invaded node among the nodes dissected. During the last 3 months of the study, the sentinel node was identified in 100% of the cases and was representative of the overall dissection. CONCLUSION: Identifying the sentinel node is an alternative to standard axillary node dissection procedures. The method requires a training period and identification can be improved with radioimmunologic guidance. Patient selection within the framework of a rigorous multidisciplinary protocol is indispensable. A nationwide study is currently being conducted to validate these preliminary results. 相似文献

Axillary lymphadenectomy in breast conservation surgery is associated with substantial morbidity in either seroma formation or infection. Seroma formation in the axilla requiring aspiration occurs in up to 42 per cent of patients treated without drainage. Prolonged outpatient suction drainage reduces but does not eliminate the incidence of seroma formation, while increasing cost, discomfort, and possibly infection rates. We studied the efficacy of overnight closed suction drainage in patients undergoing breast conservation surgery. Fifty consecutive patients undergoing a standard axillary dissection for breast cancer were studied. The axilla was drained with a 7-French closed suction drain. All drains were removed within 23 hours of surgery and prior to discharge from the outpatient surgical center. Patients were examined by the operating surgeon 7 to 10 days after surgery. One patient (2%) experienced a seroma postoperatively. No infections were observed in all 50 patients, and the remaining 49 patients did not experience visible or symptomatic seromas. The number of lymph nodes removed ranged between 5 and 33 with a mean of 15.5 +/- 0.6. Nine out of 50 (18%) patients had metastatic breast cancer to the axillary lymph nodes. Patients undergoing breast conservation surgery benefit from overnight closed suction drainage of the axilla. This short-term method reduces the incidence and the inherent morbidity of axillary seroma formation. 相似文献

The series consists of 49 operable breast cancers, prospectively registered over a five month period. The removed axillary fat was peroperatively radiologically examined by trained radiologist, and the result was reported to the surgeon. Afterwards it was sent to the pathologist for a thorough histopathological examination. Peroperative radiographic examination showed that 30.6% of the resected axillary fat contained less than ten lymph nodes. Subsequent pathological examination found that only 8.2% actually contained less than ten lymph nodes. We conclude that peroperative radiological examination of removed axillary fat is not a reliable method to assess the number of lymph nodes removed during the surgical procedure. In our hands, a careful anatomical dissection removing all axillary fatty tissue and lymphatics including level I and II seems to be the method of choice. 相似文献

Axillary node dissection for breast cancer is important for staging and prognosis. "Sentinel nodes" are the first nodes into which primary cancer drains. Identification, removal and pathological examination of those nodes indicates whether completion of axillary lymphadenectomy is required. The sentinel nodes are identified using a vital dye injected at the primary tumor site. With this technique we were able to identify sentinel nodes in 46 of 48 (95%) women examined. An average of 2.7 +/- 1.2 nodes were identified as sentinel nodes. In 81% of cases there was a correlation between involvement of sentinel nodes and of other axillary nodes as well. In 10% of patients sentinel nodes were involved with tumor while other axillary nodes were negative. The major problem in routine application of this is relationship in surgical decisions is reliable real time pathological identification of lymph node involvement by tumor. 相似文献

In light of the changing trends in the diagnosis and management of invasive breast cancer, the practice of routine axillary dissection should be reevaluated. A growing number of patients with breast cancer are diagnosed as having small tumors with an associated low risk of lymph node metastases. The pathologic features of the primary tumor are increasingly being used as a prognostic guide for recommendations about adjuvant systemic therapy, and there are recent reports suggesting a superior prognostic value for tumor cells detected in bone marrow, as compared to axillary lymph node metastases. Consequently, axillary lymph node status is no longer the single prognostic guide for recommendations about adjuvant systemic therapy. For treatment of the axilla, there is evidence that, in clinical N0 patients, radiation therapy to the axilla is an effective alternative to axillary dissection. Finally, there are cost and morbidity considerations for patients undergoing axillary dissection in whom the indications of the procedure are equivocal. In the management of invasive breast cancer, a selective policy toward axillary lymph node dissection should be considered. This review discusses the nonsurgical management of the axilla; ie, radiation therapy to the axilla and observation of the axilla as an alternative to axillary dissection. 相似文献

Lymphoscintigraphy associated with radioguided biopsy of the sentinel node (SN) is well established in clinical practice for melanoma. In breast cancer, the SN concept is similarly valid, and lymphoscintigraphy is a useful method for localizing the axillary SN. The aim of this study was to optimize the lymphoscintigraphy technique in association with a gamma ray detecting probe (GDP) for identifying and removing the SN in breast cancer patients. METHODS: Two-hundred fifty patients with operable breast tumor underwent lymphoscintigraphy before surgery. Three different size ranges of 99mTc-labeled colloid particles (<50, <80 and 200-1000 nm) were used, with either subdermal (above tumor) or peritumoral injection. Early and late scintigraphic images were obtained in anterior and oblique projections, and the skin projection of the detected SN was marked. Sentinel nodes were identified and removed with the aid of the GDP during breast surgery; they were tagged separately. Complete axillary dissection followed. In 40 patients, a blue dye was also administered in addition to subdermal radiolabeled colloid to compare blue dye mapping with lymphoscintigraphy localization. RESULTS: Lymphoscintigraphy successfully revealed lymphatic drainage in 245 of 250 patients (98%). The axillary SN was identified in 240 patients (96%). SN biopsy correctly predicted axillary node status in 234 of 240 patients (97.5%). Lymphoscintigraphy and GDP detected the SN most easily and consistently when 200-1000 nm colloid was administered subdermally in an injection volume of 0.4 ml. Blue dye mapping was successful in 30 of 40 patients (75%). In 26 of these patients, the dye and lymphoscintigraphy identified the same node; in 4 cases different nodes were identified. None of these four patients had axillary disease. CONCLUSION: Lymphoscintigraphy is a simple procedure that is well tolerated by patients. Sentinel node identification is more reliable when large-size radiolabeled colloids are injected in a relatively small injection volume (0.4 ml). Use of a GDP greatly facilitates precise pinpointing and rapid removal of the SN. 相似文献

OBJECTIVE: The authors assessed the impact of axillary dissection on adjuvant systemic therapy recommendations in patients with breast cancer. SUMMARY BACKGROUND DATA: With increasing use of systemic therapy in node-negative women and the desire to reduce treatment morbidity and cost, the need for axillary dissection in clinically node-negative patients with breast cancer has been challenged. METHODS: Two hundred eighty-two women with clinically negative axillae were analyzed using a model treatment algorithm. Systemic therapy was assigned with and without data from axillary dissection. Treatment shifts based on axillary dissection data were scored. RESULTS: Twenty-seven percent of clinically node-negative women had pathologically positive nodes. Eight percent of T1a and 10% of T1b tumors had positive nodes and would have been undertreated without axillary dissection. Seven percent of premenopausal women with tumors < 1 cm and 13% with tumors > or = 1 cm had treatment changed by axillary dissection. For women 50 to 60 years of age, 10% with tumors < 1 cm, 17% with tumors 1 to 2 cm with positive prognostic features, and 4% with poor prognostic features had significant treatment shifts after axillary dissection. For clinically node-negative women older than 60 years of age not eligible for chemotherapy, only 3% of those with tumors < 1 cm and none of those with tumors > or = 1 cm had their treatment changed by findings at axillary dissection. Treatment shifts based on axillary dissection were larger if the treatment algorithm allowed for more varied or more aggressive treatment options. CONCLUSIONS: Data obtained from axillary dissection will alter adjuvant systemic therapy regimen in a significant number of clinically node-negative women younger than 60 years of age and for older women eligible to receive chemotherapy. 相似文献

Sentinel-node biopsy to avoid axillary dissection in breast cancer with clinically negative lymph-nodes 总被引:4,自引:0,他引:4

BACKGROUND: Axillary lymph-node dissection is an important staging procedure in the surgical treatment of breast cancer. However, early diagnosis has led to increasing numbers of dissections in which axillary nodes are free of disease. This raises questions about the need for the procedure. We carried out a study to assess, first, whether a single axillary lymph node (sentinel node) initially receives malignant cells from a breast carcinoma and, second, whether a clear sentinel node reliably forecasts a disease-free axilla. METHODS: In a consecutive series of 163 women with operable breast carcinoma, we injected microcolloidal particles of human serum albumin labelled with technetium-99m. This tracer was injected subdermally, close to the tumour site, on the day before surgery, and scintigraphic images of the axilla and breast were taken 10 min, 30 min, and 3 h later. A mark was placed on the skin over the site of the radioactive node (sentinel node). During breast surgery, a hand-held gamma-ray detector probe was used to locate the sentinel node, and make possible its separate removal via a small axillary incision. Complete axillary lymphadenectomy was then done. The sentinel node was tagged separately from other nodes. Permanent sections of all removed nodes were prepared for pathological examination. FINDINGS: From the sentinel node, we could accurately predict axillary lymph-node status in 156 (97.5%) of the 160 patients in whom a sentinel node was identified, and in all cases (45 patients) with tumours less than 1.5 cm in diameter. In 32 (38%) of the 85 cases with metastatic axillary nodes, the only positive node was the sentinel node. INTERPRETATION: In the large majority of patients with breast cancer, lymphoscintigraphy and gamma-probe-guided surgery can be used to locate the sentinel node in the axilla, and thereby provide important information about the status of axillary nodes. Patients without clinical involvement of the axilla should undergo sentinel-node biopsy routinely, and may be spared complete axillary dissection when the sentinel node is disease-free. 相似文献

The primary purpose of this study was to evaluate the prognostic significance of Ki-67, a cell proliferation-associated antigen, in a large group (n = 674) of axillary node-negative breast cancer cases with long-term follow-up and to correlate Ki-67 antigen expression with S-phase fraction. Ki-67 immunostaining was assessed both semiquantitatively and quantitatively. The statistical analysis focused on agreement between methods of Ki-67 quantification, agreement between Ki-67 and S-phase fraction, associations between Ki-67 and other clinical variables, and prognostic value of Ki-67. There was excellent agreement between the two methods of Ki-67 assessment (Spearman rank correlation, rsp = 0.91; P = 0.0001; n = 674) but only weak correlation between either semiquantitative or quantitative Ki-67 and S-phase fraction (rsp = 0.12 and rsp = 0.15, respectively). Ki-67 (overall median, 2%) was independent of tumor size and modestly related to other measures of tumor aggressiveness. Using a cutpoint of 5% (percentage of tumor cells), cases with high Ki-67 exhibited a significantly shorter disease-free survival (Padj = 0.004). In multivariate analysis, high Ki-67 was associated with a 1.8-fold increased risk of recurrence (P = 0.001). In the subgroup with S-phase data, the adjusted relative risk (hazard ratio, 1.9; P = 0.02) was unchanged by inclusion of S phase in the model. This suggests that Ki-67 provides significant independent prognostic information in addition to that contained in tumor size and S-phase fraction. 相似文献

Xeroradiographic evaluation of the axilla is useful in the presence of mammary carcinoma, as radiographic examination of this area can be highly accurate in predicting its malignant involvement if certain strict criteria are employed. The ability to diagnose nodal metastases with near certainty has important implications for treatment planning and prognostication. 相似文献

BACKGROUND: Induction chemotherapy has become the standard of care for patients with locally advanced breast cancer (LABC) and currently is being evaluated in prospective clinical trials in patients with earlier-stage disease. To better gauge the role of axillary lymph node dissection in patients with LABC this study was performed to assess initial axillary status on physical and ultrasound examination, axillary tumor downstaging following induction chemotherapy, and the accuracy of physical examination compared with axillary sonography in predicting which patients will have axillary lymph node metastases found on pathologic examination. METHODS: Between 1992 and 1996, 147 consecutive patients with LABC were registered in a prospective trial of induction chemotherapy using 5-fluorouracil, doxorubicin, and cyclophosphamide. Physical and ultrasound examinations of the axilla were performed at diagnosis and after induction chemotherapy. Segmental resection with axillary lymph node dissection or modified radical mastectomy was performed, followed by postoperative chemotherapy and irradiation of the breast or chest wall and regional lymphatics. RESULTS: Following induction chemotherapy, 43 (32%) of the 133 patients with clinically positive lymph nodes on initial examination had axillary tumor downstaging as assessed by physical and ultrasound examination. The sensitivity of axillary sonography in identifying axillary metastases was significantly higher than that of physical examination (62% vs. 45%, P=.012). The specificity of physical examination (84%) was higher than that of sonography (70%), but the difference did not reach statistical significance. Among the 55 patients in whom the findings of both physical and ultrasound examination of the axilla were negative following induction chemotherapy, 29 patients (53%) were found to have axillary lymph node metastases on pathologic examination of the axillary contents. However, 28 (97%) of these patients had either 1 to 3 positive lymph nodes or only micrometastases 2 to 5 mm in diameter. CONCLUSIONS: Preoperative clinical assessment of the axilla by physical examination combined with ultrasound examination is not completely accurate in predicting metastases in patients with LABC following tumor downstaging. However, patients with negative findings on both physical and ultrasound examinations of the axilla may be potential candidates for omission of axillary dissection if the axilla will be irradiated because minimal axillary disease remains. Patients who have positive findings on preoperative physical or ultrasound examinations should receive axillary dissection to ensure local control. A prospective randomized trial of axillary dissection versus axillary radiotherapy in patients with a clinically negative axilla following induction chemotherapy is currently underway. 相似文献

We treated 10 patients with recurrent anterior dislocation of the shoulder by transplantation of pectoralis minor muscle-bone flap transplanted to the upper part of the humerus. All patients were followed-up for an average 31 months and no recurrent was found. We consider that the muscle beily exerts a protective effect like a barrier on the weak anterio inferior region of the shoulder and increases the force for extending the shoulder and lifting the arm. The operation is based on biomechanics. Meanwhile, suturing the laxative joint capsule and repairing the weak anteroinfeior region of the shoulder is more beneficial to prevent from redislocation of the humerus head. 相似文献

The staging and prognosis of patients with breast cancer is related to the presence or absence of axillary lymph node involvement. However, in some cases no lymph nodes or too small a number of lymph nodes are revealed by the traditional method of palpating and sectioning the axillary fat. In the present study we demonstrate the usefulness of the lymph node revealing solution (LNRS) in breast cancer. Specimens from 13 patients, in whom <10 lymph nodes were identified in the axilla by the traditional method, were included in the study. After excising the lymph nodes by the traditional method, axillary tissue was immersed in LNRS for 6-12 hours. Additional lymph nodes, which stood out as white chalky nodules, were excised and processed as usual. The LNRS increased the mean number of nodes per case from 6.0+/-2.5 found by the traditional method to 12.54+/-4.61 nodes per case (p < 0.01). The size of the nodes identified by the LNRS was significantly smaller (p < 0.01) than those detected by the traditional method. The LNRS changed the lymph node stage of the disease in four of the studied cases (30%). LNRS seems to be the technique of choice for detection of axillary lymph nodes in cases where the number of detected lymph nodes by the traditional method is too small for accurate staging. 相似文献
