Nipple-sparing mastectomy with different approaches: surgical incisions, complications, and cosmetic results. Preliminary results of 100 consecutive patients at a single center.

Nipple- and areola-sparing mastectomy is a novel surgical approach that preserves the nipple-areolar complex. Patients with moderate and/or severe breast ptosis are usually not eligible for this surgical approach. In this study, we aimed to demonstrate the feasibility of nonconventional surgical approaches for nipple-sparing mastectomy. One hundred consecutive patients diagnosed with primary breast cancer (BC) were enrolled in this study. Clinical and pathological data such as body mass index, smoking status, breast ptosis, complications, and aesthetic satisfaction (Breast-Q test) were collected. According to different types of breast ptosis, surgical procedures were classified as (a) hemi-periareolar, (b) round block, (c) vertical pattern, and (d) wise pattern skin incisions. We performed statistical analysis to assess the correlation with complications, degree of ptosis, and breast-Q scores. Among the 117 surgical procedures performed in 100 patients with BC, no significant associations are verified considering clinical and pathological data, complications, pre- and postsurgery satisfactions, and other parameters. Different surgical approaches represent the evolution of "classic" nipple-sparing mastectomy, thus meeting the cosmetic and oncological results. These procedures are safe and also indicated in cases conventionally considered as not eligible for nipple-areola preservation.

Sentinel node biopsy after neoadjuvant treatment in breast cancer: Five-year follow-up of patients with clinically node-negative or node-positive disease before treatment.

PURPOSE: It is controversial whether sentinel node biopsy (SNB) without axillary dissection (AD) should be performed in cN1/2 breast cancer patients who become cN0 after neoadjuvant treatment, since the false negative rate (FNR) may be unacceptably high. We assessed outcomes to address this issue. METHODS: We retrospectively assessed 396 cT1-4, cN0/1/2 patients, who became or remained cN0 after neoadjuvant treatment and underwent SNB with at least one sentinel node (SN) found, and AD not performed if the SN was negative. RESULTS: After a median follow-up of 61 months (interquartile range 38-82), five-year overall survival was 90.7% (95% CI, 87.7-93.7) in the whole cohort, 93.3% (95% CI, 90.0-96.6) in those initially cN0, and 86.3% (95% CI, 80.6-92.1) in those initially cN1/2 (P = 0.12). Axillary failure occurred in only 1 (0.7%) initially cN1/2 patient who became cN0. In initially cN0 patients, and also initially cN1/2 patients who responded well to neoadjuvant treatment (ypT0/ypTx), SN-negativity was a significant predictor of good outcome, consistent with the known prognostic significance of axillary status, and suggesting that SN status accurately reflected axillary status. By contrast, in initially cN1/2 patients found to be ypT1/2/3, SN status (and whether or not AD was performed) had no influence on survival. CONCLUSIONS: These findings suggest that SNB is acceptable in cN1/2 patients who become cN0 after neoadjuvant therapy.

Sentinel lymph node biopsy for localised ductal carcinoma in situ?

Intraductal carcinoma of the breast (DCIS), by definition, cannot give axillary metastases. Axillary dissection is therefore not indicated. The role of the sentinel lymph node (SLN) biopsy in the management of DCIS has not yet been established. A 6-13% risk of SLN involvement is reported in Literature. The aim of the present study is to assess the role of SLN biopsy in patients with pure DCIS and attempt to identify guidelines for routine practice in managing such patients. From March 1996 to December 2003, 508 consecutive patients with pure DCIS of the breast underwent SLN biopsy at the European Institute of Oncology in Milan. Clinical and pathological data were prospectively collected. In all cases of previous surgery or stereotactic biopsy performed elsewhere all pathological slides were reviewed. Cases with microinvasion were excluded from this investigation. Lymphatic mapping was performed using a radiocolloid technique. Most of the patients underwent conservative surgery and removal of the SLN which was sent for conclusive histology. SLN metastases were detected in 9 out of 508 (1.8%) patients. In five patients only micrometastasis (<2 mm) was detected. Eight patients underwent complete axillary dissection. In none of these patients did we find additional positive axillary lymph nodes. In conclusion, due to the low prevalence of metastatic involvement (1.8%), SLNB should not be considered a standard procedure in the treatment of all patients with DCIS. In pure non-comedo DCIS completely excised by radical surgery with free margins of resection SLNB should be avoided since not only it is unnecessary but could also jeopardize a successive re-SLNB in case of invasive recurrence. A very extensive and accurate histological examination of the tumour in DCIS is compulsory to exclude micro-invasive foci and, finally, to decrease the prevalence of unexpected SLN metastases. SLNB should be considered in case of DCIS where there exists a strong doubt of invasion at the definitive histology, such as large solid tumours or diffuse or pluricentric microcalcifications undergoing mastectomy. Moreover, if the trend is statistically confirmed with a wider population, large comedo-DCIS, presenting superior risk of SLNs metastasis, could be scheduled for SLNB. If the SLN is micrometastatic complete axillary dissection is not unavoidable.

Paraneoplastic neurological disorders in breast cancer.

Paraneoplastic syndromes are the rarest neurological complications in patients with cancer. The neurological paraneoplastic syndromes that are mainly associated with breast cancer are subacute cerebellar degeneration, paraneoplastic retinopathy, opsoclonus-myoclonus syndrome, lower motor neuron diseases and Stiff-man syndrome. The aim of this paper is to briefly outline these paraneoplastic neurological syndromes and consider their relation to breast carcinoma.

[Follow-up of surgical biopsies in microcalcifications of the breast. Comparative analysis of patients submitted to mammography and digitalization of mammographic images]. / Il follow-up delle biopsie chirurgiche per microcalcificazioni della mammella. Analisi comparata tra pazienti sottoposte a mammografia e a digitalizzazione dell'immagine mammografica.

Improvements in the techniques of preoperative needle localization of nonpalpable breast lesions that have been detected at mammography, coupled with surgical biopsy of smaller volumes of breast tissue and the use of local anesthesia have produced a more aggressive attitude toward early biopsy of lesions that are suspected of malignancy. The authors report the follow-up in 92 cases, who underwent breast biopsy for microcalcifications with no palpable lesions. In 46 women the presence of microcalcifications was evaluated through a computerized instrument which allows digitalization of the image.
