In the sentinel node era, axillary dissection (ALND) for breast cancer (BC) is required much less frequently than in the past. However, complications, such as prolonged drainage output and seroma formation, are still observed. Harmonic dissection devices (HDDs) are widely used in laparoscopic and minimally invasive surgery to reduce collateral damage during tissue dissection, but its usefulness in breast surgery is unclear. The aim of this study was to evaluate the efficacy of HDDs compared to that of conventional dissection in performing ALND. One hundred thirty-nine women (median age 61 years, range 34–71 years) with confirmed pT1–2 primary infiltrating ductal BC undergoing curative surgery were enrolled in the study. The population was prospectively randomized between two age- and stage-matched arms: group A (cases)—68 (48.9 %) patients (HDD technique), versus group B (controls)—71 (51.1 %) patients (conventional technique). In group B, skin flaps were obtained using a scalpel, scissors, and electrocautery which was never used for ALND. In group A, for each operation time, the HDDs were used exclusively. The mean operative time, intraoperative blood loss, and drainage output were (A vs. B) 95 ± 22 versus 109 ± 25 min, 56 ± 12 versus 86 ± 15 mL, and 412 ± 83 versus 456 ± 69 mL, respectively (p < 0.01). Twenty-nine (20.9 %) patients developed an axillary seroma: 9 (13.2 %) and 20 (28.2 %) for groups A and B, respectively (p = 0.030). Our study confirms that in patients with BC requiring ALND the use of HDDs is more time efficient than conventional surgery, and reduces intraoperative bleeding, the amount of drainage, and the risk of seroma formation. These results may lead to several short- and long-term advantages. Thus, a careful evaluation of the cost–benefits of nontraditional tools, such as HDDs, should be performed in all patients undergoing modified radical or partial mastectomy and ALND for BC. 相似文献

Epstein–Barr virus (EBV) type and strain variations were examined using both lymphoblastoid cell lines (LCLs), spontaneously derivedin vitrofrom peripheral blood mononuclear cells (PBMC) of 15 HIV-1-seropositive individuals, and SCID mouse tumours induced by inoculation of PBMC from 11 healthy human donors (Hu-SCID tumours). Polymerase chain reaction (PCR) analysis disclosed that all but one of the 26 EBV+ samples harboured EBV nuclear antigen (EBNA) 2 and 3C type A virus. On the other hand, single strand conformation polymorphism (SSCP) analysis using Epstein–Barr encoded RNA (EBER) specific primers detected an AG876-like (type B) band pattern in 21 of the 26 EBV+ samples. Three Hu-SCID tumours scored as B95.8-like (type A), and two showed neither a type A nor a type B SSCP migration pattern. Sequence analysis of the amplified EBER fragments confirmed the PCR-SSCP findings; moreover, additional mutations were present not only in the two EBV+ samples with anomalous SSCP pattern, but also in two other samples with a standard SSCP profile. Thus, EBER analysis did not correlate with EBNA typing, and appeared to be unsuitable for EBV type assessment. Latent membrane protein (LMP) analysis disclosed, on the whole, seven size variants: as expected, the differences were due to the variable numbers of a 33-bp repeat in the amplified fragment, as assessed by direct sequencing. The broader variability detected by LMP analysis should prove more useful than typing for assessing the presence of single and/or mixed variants resulting from EBV reactivation and/or reinfection. 相似文献

The binding of the receptor for advanced glycation end products (RAGE) with its ligands begins a sustained period of cellular activation and inflammatory signal amplification in different tissues and diseases. This binding could represent an as yet uninvestigated pathway of inflammatory reaction in the lung, where the presence of the receptor has been largely documented and advanced glycation end products (AGEs) are produced by nonenzymatic glycation and oxidation of proteins and lipids, driven by smoke and pollutants exposure or inflammatory stress. We immunohistochemically assessed the expression of RAGE and of its major proinflammatory ligands, N-epsilon-carboxy-methyl-lysine, S100B and S-100A12 in normal lung and in non-neoplastic lung disorders including smoke-related airway disease, granulomatous inflammation, postobstructive damage and usual interstitial pneumonia. In normal lung low expression of the receptor was observed in bronchiolar epithelia, type II pneumocytes, macrophages and some endothelia. S100A12 and S100B were expressed, respectively, in granulocytes and in dendritic cells. Carboxy-methyl-lysine was present in bronchiolar epithelia and macrophages. In all pathological conditions associated with inflammation and lung damage overexpression of both the receptor and of AGEs was observed in bronchiolar epithelia, type II alveolar pneumocytes, alveolar macrophages and endothelia. RAGE overexpression was more evident in epithelia associated with inflammatory cell aggregates. Fibroblasts in usual interstitial pneumonia expressed both the receptor and AGEs. The number of S100A12 and S100B immunoreactive inflammatory cells was variable. S100A12 was also expressed in mononuclear inflammatory cells and in activated epithelia. The activation of the inflammatory pathway controlled by the RAGE is not specific of a single lung disease, however, it may be relevant as a nonspecific pathway of sustained inflammation in lung tissue, and on this basis therapeutic approaches based on receptor blockage can be envisaged. 相似文献

The authors report their experience on the use of a biopsy gun for histological sampling in the field of breast lesions. The use of cytological sampling by (FNAB) fine needle aspiration biopsy has been preferred so far, because it has been thoutht to be simpler, less risky and reliable. Nevertheless, the cytological sampling shows a number of drawbacks such as the need for passes to get sufficient cellular material, frequent problems in diagnosing benign lesions and the decisive influence of the operator's skill. By using a biopsy gun for histological sampling these disadvantages are eliminated. In this case, in fact, the validity of the sample is not influenced by the operator's skill; fewer passes are necessary and their validity does not depend on the nature of the lesion. The personal series of cases involves 91 patients subjected to histological sampling for suspected lesions. Two different kinds of needles were used with one an 18 G diameter and a 23-mm extension of the sytlet, as well as a sampling window 17 mm; the other with the same diameter and extension of the stylet, as as a sampling window 8 mm. The first needle was used in all 91 patients, and the second only in 30. The results were not influenced by the employ of the different kinds of needles. A total of 268 samples were made and 110 lesions were discovered, 79 of which were malignant and 31 benign (fibroadenoma, fibrocystic change and epitheliosis). Three carcinomas were not found (3 false-negative) and one specimen was inadequate. The values of sensibility, specificity and diagnostic accuracy of the method were, respectively, 96.2%, 100% and 97.2%, with 3.8% false-negative due to three cases where the lesion was not centred for guidance mistake. 相似文献

A prospective study was carried out on a recent marker for breast cancer, CA549, a mucine-like acid glycoprotein present in the fat membranes of human milk. Fifty healthy control subjects and 91 with benign conditions, 103 mammary cancer patients and 256 patients with other types of malignancy were studied. For comparison, CEA and CA15-3 were also investigated. The CA549 cutoff was 11 U/ml. In breast cancer the marker was below the cutoff in 9 cases (92.8%); in malignancies other than breast cancer it was above the cutoff in 5 to 50% of patients. In breast cancer it was raised in 83.3% of cases (CA15-3 showed 82.9% and CEA 50%). In breast cancer after radical surgery, CA549 was normal in patients who were in TNM stage I but above the cutoff in 57.1% of those at more advanced stages. The follow-up study is ongoing among these patients. In all the study conditions, CA549 favorably compared to CA15-3 values, with sensitivity and specificity greater than CEA. 相似文献

Objective: A significant proportion of breast cancer patients experiences psychiatric morbidity in the first year after a breast cancer diagnosis and/or beginning of treatment. This study attempted to identify and understand the risk factors for developing such problems. Methods: A consecutive series of 87 patients, aged 40–75 years, was assessed prior to diagnosis of breast cancer and followed-up approximately 8 weeks after beginning of cancer treatment and again 9 months after first follow-up. Assessments included measures of psychiatric morbidity using the General Health Questionnaire (GHQ-12), coping style using the Mental Adjustment to Cancer (MAC) Scale, symptom attribution, beliefs about breast cancer, social support, socio-demographic and clinical variables. Results: A total of 85.1% of patients completed both follow-ups. Pre-diagnostically, 32.2% of breast cancer patients scored as a GHQ-12 ‘case.’ GHQ scores fell significantly between pre-diagnostic and both post-diagnostic assessments, especially in women who had thought they had cancer. Predictors of psychological morbidity at first follow-up included pre-diagnostic GHQ-12 score, lack of social support and feelings of ‘personal responsibility/avoidance.’ GHQ-12 ‘caseness’ at second follow-up was predicted by lack of social support alone. Conclusions: Overall, psychiatric morbidity is higher prior to, than following, a definitive diagnosis of breast cancer. Early reactions of this kind are predictive of post-treatment adjustment. However, only the presence of social support in this study seems to be associated with successful adjustment in the first year following a breast cancer diagnosis. Women at increased risk of psychological morbidity after a breast cancer diagnosis may be thus identifiable and targeted therapeutically. 相似文献
