Sentinel node biopsy and radical lymph node dissection for advanced melanoma in the elderly

Articolo presente su PubMed Central. Sourcerecord Id Scopus: 28558 http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3194399/ Background.The majority of indications for surgery in melanoma are for the treatment of primary tumor and lymph node metastases. During the last decade, the Sentinel Node Biopsy (SNB), from a research procedure, has become standard of care in most institutions. SNB is normally considered for patients with melanoma > 1 mm and generally about 20% are positive; however, the risk of a positive SNB in a melanoma < 1 mm is still 5%. Usually when SNB is positive a complete lymphadenectomy is performed. Materials and methods.In the period 2004-2009, 18 elderly patients (median age 68 years) affected by cutaneous melanoma (mean Breslow’s thickness = 3.77 mm), after SNB histologically confirmed regional lymph node involvement, underwent complete lymph node dissection (CLND). We treated 11 of them with groin dissection, in 3 cases bilateral; 4 patients underwent axillar dissection, in one case bilateral; 2 patients underwent neck dissection and another patient underwent groin-axillar dissection. We treated bilateral groin involvement with laparoscopic access for dissection of lumbar-aortic, iliac and obturator lymph nodes. Results.Disagreeing with literature, 12/18 (67%) of these patients had positive lymph nodes, a high percentage if compared with younger patients’ data. Currently the average follow-up is 25 months. In our sample CLND has a crucial prognostic role (16% vs 41% of deceased in CLND – and CLND + patients respectively). Conclusions.Elderly melanoma patients are characterized by a higher tumor stage and, in patients with nodal metastases, the prognosis is independently affected by older age. In case of positive SNB the CLND plays a notable prognostic role and a presumable therapeutic role

Flap fixation in preventing seroma formation after mastectomy: an updated meta-analysis

Seroma formation following mastectomy is one of the most experienced complications, with a very variable incidence ranging from 3 to 90%. In recent years, many publications have been realized to define an effective technique to prevent its formation and several approaches have been proposed. Given the potential of flap fixation in reducing seroma formation, we performed a meta-analysis of the literature to investigate the role of this approach as definitive gold standard in mastectomy surgery. Inclusion criteria regarded all studies reporting on breast cancer patients undergoing mastectomy with or without axillary lymph node dissection; studies that compared mastectomy with flap fixation to mastectomy without flap fixation were selected. Papers were eligible for inclusion if outcome was described in terms of seroma formation. As secondary outcome, also surgical site infection (SSI) was evaluated. The included studies were 12, involving 1887 female patients: 221/986 (22.41%) patients experienced seroma formation after flap fixation and 393/901 (43.61%) patients had this complication not receiving flap fixation, with a significant statistical difference between the two groups (OR = 0.267, p = 0.001, 95% CI 0.153, 0.464). About, SSI 59/686 (8.6%) in flap fixation group and 67/686 (9.7%) in patients without flap fixation, with no statistical differences between groups (OR = 0.59, p = 0.056, 95% CI 0.344, 1.013). The heterogeneity between included studies does not allow us to reach definitive conclusions but only to suggest the strong evaluation of this approach after mastectomy in seroma preventing and SSI reduction

The first case of acinic cell carcinoma of the breast within a fibroadenoma: Case report

AbstractA case of acinic cell carcinoma of the breast is reported in a 26-year-old woman. She presented a lump in her right breast, that seemed to be a fibroadenoma. The open biopsy revealed a well-bordered fibroadenoma, together with a proliferation of cells characterized by serous acinar differentiation and eosinophilic cytoplasmic granules. Tumor cells stained for amylase, lysozyme, α-1-antichymotripsin, epithelial membrane antigen, S-100 protein, pan-cytokeratin, cytokeratin 7 and E-cadherin. Estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2 overexpression, CD10, P63, smooth muscle actin, cytokeratin 5/6 were negative. The sentinel node was negative. 8 months after surgery she is in good clinical conditions without recurrence or metastases

\u201cA randomised factorial trial of sequential doxorubicin and CMF vs CMF and chemotherapy alone vs chemotherapy followed by goserelin plus tamoxifen as adjuvant treatment of node-positive breast cancer\u201d

The sequential doxorubicin \u2192 CMF (CMF = cyclophosphamide, methotrexate, fluorouracil) regimen has never been compared to CMF in a randomised trial. The role of adding goserelin and tamoxifen after chemotherapy is unclear. In all, 466 premenopausal node-positive patients were randomised to: (a) CMF 7 6 cycles (CMF); (b) doxorubicin 7 4 cycles followed by CMF 7 6 cycles (A \u2192 CMF); (c) CMF 7 6 cycles followed by goserelin plus tamoxifen 7 2 years (CMF \u2192 GT); and (d) doxorubicin 7 4 cycles followed by CMF 7 6 cycles followed by goserelin plus tamoxifen 7 2 years (A \u2192 CMF \u2192 GT). The study used a 2 7 2 factorial experimental design to assess: (1) the effect of the chemotherapy regimens (CMF vs A 7 CMF or arms a + c vs b + d) and (2) the effect of adding GT after chemotherapy (arms a + b vs c + d). At a median follow-up of 72 months, A \u2192 CMF as compared to CMF significantly improved disease-free survival (DFS) with a multivariate hazard ratio (HR) = 0.740 (95% confidence interval (CI): 0.556-0.986; P = 0.040) and produced a nonsignificant improvement of overall survival (OS) (HR = 0.764; 95% CI: 0.489-1.193). The addition of GT after chemotherapy significantly improved DFS (HR = 0.74; 95% CI: 0.555-0.987; P = 0.040), with a nonsignificant improvement of OS (HR = 0.84; 95% CI: 0.54-1.32). A \u2192 CMF is superior to CMF. Adding GT after chemotherapy is beneficial for premenopausal node-positive patients. \ua9 2005 Cancer Research UK

Sentinel lymph node identification in breast cancer patients

Purpose. To evaluate the predictive value of sentinel lymph node biopsy versus axillary node dissection on lymph node status in patients with T1-T2 breast cancer. Material and methods. Twentynine patients with T1 and 12 with T2 breast carcinoma and clinically NO axillary lymph nodes, underwent lymphoscintigraphy following the administration of 99mTc-human albumin nanocolloids. The tracer was injected subdermally, over the tumor mass, in the 34 patients with palpable lesions and peritumorally (n=3) or intratumorally (n=4), under stereotactic or ultrasound guidance, in the 7 patients with non-palpable lesions. Anterior and lateral planar images were acquired 15 min after the injection of the tracer and repeated every 30 min up to 3 hr until identification of sentinel lymph node. At the end of the scintigraphic study, sentinel node skin projection was marked using a demographic pen. Eighteen hours after lymphoscintigraphy, sentinel lymph node was identified and removed during surgery by hand-held gamma probe, then, the remaining axillary lymph nodes were dissected. All surgical specimens underwent histologic examination. Sentinel lymph nodes free of metastasis at histology, underwent additional examination with immunohistochemistry using monoclonal antibodies against cytokeratin and EMA to search for micrometastases. Results. Sentinel lymph node was identified in the 34 patients injected subdermally and in the 3 patients injected peritumorally, while it remained undetected in the 4 patients injected intratumorally except for one case in which it was isolated by radioguided surgery but not scintigraphically. Sentinel nodes resulted free of metastases both at histology and immunohistochemistry in 32 cases and metastatic in 6. In the 32 patients with non-metastatic sentinel lymph nodes the other axillary nodes were also free of metastases. Among the 6 metastatic sentinel lymph nodes, in 3 cases they were the only metastatic nodes of the axilla while in the other 3 cases metastases were spread to other axillary nodes. Conclusions. In agreement with previous studies, our results showed that sentinel lymph node radioguided biopsy is a simple and reliable method for predicting axillary lymph nodes status and for avoiding axillary dissection in early breast cancer patients with sentinel node free of metastases
