Sentinel lymph node biopsy (SLNB) is a minimally invasive technique to stage the axillary lymph node status. The burden of nodal metastasis is of great concern, as the clinical relevance and therapeutic implications of pN1mi and pN0(i+) in the sentinel lymph node (SLN) remain a matter of debate.We examined the pathological features of 901 patients above the age of 65 presenting with clinical T1-T2 N0M0 breast tumours (3 cm), detecting tumours related to llary non-sentinel node (NSN) metastases when the SLN was minimally involved.A total of 270 patients underwent complete axillary lymph node dissection (cALND) after their SLNB specimen tested positive for macrometastasis, micrometastasis and isolated tumour cells (ITCs). Seventy-six patients were diagnosed with micrometastatic disease pN1mi (27.5%), whilst ITCs (pN0i+) were detected in seven patients (2.5%). NSNs were found to be involved in two patients (2.6%) with micrometastases at the SLN. No further metastatic disease was detected in NSNs when the SLN contained ITCs. At a median follow-up period of 5.8 years, no axillary recurrence was observed among pN1mi and pN0(i+) patients. Lobular histotype, multicentricity and lymphovascular invasion were found to be associated with NSN involvement.The results from our case series are supported by IBCSG 23-01 level 1 evidence, which demonstrated a local recurrence rate of 1% in 'minimally involved not-surgical treated axilla'.Based on current evidence, we spare well-informed and consenting patients from further axillary surgery when the SLN is minimally involved in early breast cancer within an agreed protocol, whilst scheduling adjuvant treatment based on the patients' primary tumour characteristics.

The minimally invasive approach to parathyroid glands represents an important field of application of radioguided surgery. As always happens, in all cases pertaining to hyper-specialized skills, scientific production has long been the prerogative of a few Authors, but the ever increasing technological diffusion, combined with excellent results often achieved, increases the interest in this technique. This is particularly true in the era of minimally invasive surgery. The Authors realize a review of the existing literature to allow an overall view of current knowledge on this particular topic and to guide future research.

With the increased age of population we can see an increase of age-related diseases, such a cardiovascular disease, hypertension, arthritis and other malignancies. With the development of endoscopy, laparoscopy, ultrasonography and biopsy equipment, more minimally invasive techniques are currently available for the surgical oncologist to provide a better optimal diagnosis and strategy, followed by an appropriate surgical treatment of biliopancreatic cancer. Improvement in the diagnostic and surgical care of elderly cancer patients will have a final impact on disease and overall survival rates of the different types of cancer treatment. Materials and methods.We retrospectively reviewed the records of patients between January 2001 and December 2008 who had either a mass in the biliopancreatic area classified as clinically resectable. Tumours were considered to be resectable when there was no evidence of distant extra pancreatic disease or involvement of lymphnodes outside the classic margins of resections. Occlusion or encasement of the superior mesenteric artery or vein, celiac artery or portal vein were used as a criteria for unresectability. Twenty-eight patients over 65 and under 75 years (middle age 69) with primary biliopancreatic cancer were submitted to operations for potentially operative resection. In all cases staging laparoscopy was performed just prior to planned open exploration and resection. Results.Twenty seven patients underwent laparoscopy exploration for potential resection. Two of five patients (40%) with distal cholangiocarcinoma survived at 5 years after DCP. Eighteen patients (66.6%) had unresectable disease identified at laparoscopy and fourteen were able to convert to laparotomy palliative surgery while for the others laparoscopy spared an unnecessary laparotomy. In four patients it was possible to perform a laparoscopy palliative surgery. Conclusions.Laparoscopy may have a role in the staging of patients with biliopancreatic malignancies, in particular, for reduction of unnecessary exploratory laparotomy. Moreover, even in old age, duodenocephalopancreasectomy, properly planned and executed, resulted in reduction of operative mortality and morbility and a clear long-term survival.

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.
