Abstract
In the last few years, innovative technology and health care digitalization played a major role in all medical fields and a great effort worldwide to manage this large amount of data, in terms of security and digital privacy has been made by different national health systems. Blockchain technology, a peer-to-peer distributed database without centralized authority, initially applied to Bitcoin protocol, soon gained popularity, thanks to its distributed immutable nature in several non-medical fields. Therefore, the aim of the present review (PROSPERO N° CRD42022316661) is to establish a putative future role of blockchain and distribution ledger technology (DLT) in the organ transplantation field and its role to overcome inequalities. Preoperative assessment of the deceased donor, supranational crossover programs with the international waitlist databases, and reduction of black-market donations and counterfeit drugs are some of the possible applications of DLT, thanks to its distributed, efficient, secure, trackable, and immutable nature to reduce inequalities and discrimination.

Abstract
Chemosensory receptors play a crucial role in distinguishing the wide range of volatile/soluble molecules by binding them with high accuracy. Chemosensation is the main sensory modality in organisms lacking long-range sensory mechanisms like vision/hearing. Despite its low number of sensory neurons, the nematode Caenorhabditis elegans possesses several chemosensory receptors, allowing it to detect about as many odorants as mammals. Here, we show that C. elegans displays attraction towards urine samples of women with breast cancer, avoiding control ones. Behavioral assays on animals lacking AWC sensory neurons demonstrate the relevance of these neurons in sensing cancer odorants: calcium imaging on AWC increases the accuracy of the discrimination (97.22%). Also, chemotaxis assays on animals lacking GPCRs expressed in AWC allow to identify receptors involved in binding cancer metabolites, suggesting that an alteration of a few metabolites is sufficient for the cancer discriminating behavior of C. elegans, which may help identify a fundamental fingerprint of breast cancer.

Abstract
The ionotropic P2X7 receptor (P2X7R) is involved in bone homeostasis but its role in osteogenesis is controversial. Thus, we investigated the expression of P2X7R and the effects exerted by its modulation in mesenchymal stromal cells from human subcutaneous adipose tissue (S-ASCs), which have potential therapeutic application in bone regenerative medicine. We found that undifferentiated S-ASCs expressed P2X7R and its functional splice variants P2X7AR and P2X7BR. Cell stimulation by P2X7R agonist BzATP (100 μM) neither modified proliferation nor caused membrane pore opening while increasing intracellular Ca2+ levels and migration. The P2X7R antagonist A438079 reversed these effects. However, 25-100 μM BzATP, administered to S-ASCs undergoing osteogenic differentiation, dose-dependently decreased extracellular matrix mineralization and expression of osteogenic transcription factors Runx2, alkaline phosphatase and osteopontin. These effects were not coupled to cell proliferation reduction or to cell death increase, but were associated to decrease in P2X7AR and P2X7BR expression. In contrast, expression of P2X7R, especially P2X7BR isoform, significantly increased during the osteogenic process. Noteworthy, the antagonist A438079, administered alone, at first restrained cell differentiation, enhancing it later. Accordingly, A438079 reversed BzATP effects only in the second phase of S-ASCs osteogenic differentiation. Apyrase, a diphosphohydrolase converting ATP/ADP into AMP, showed a similar behavior. Altogether, findings related to A438079 or apyrase effects suggest an earlier and prevailing pro-osteogenic activity by endogenous ATP and a later one by adenosine derived from endogenous ATP metabolism. Conversely, P2X7R pharmacological stimulation by BzATP, mimicking the effects of high ATP levels occurring during tissue injuries, depressed receptor expression/activity impairing MSC osteogenic differentiation.

Abstract
Background and Objectives: The surgical choice treatment of the breast cancer mostly depends on the stage of the disease. In the last years, breast cancer surgery has moved from being destructive to being more respectful of the anatomical and physiological integrity of the gland. The aim of the breast surgery should be finalized to obtain the best aesthetic and functional results, respecting the principles of oncologic radicality. The present study is a retrospective analysis aimed to evaluate the long-term outcomes of a conservative technique like the nipple-sparing mastectomy. Materials and Methods: We observed 894 patients with a median age of 47.5 years old, underwent nipple-sparing mastectomy between 2002–2017. The data acquired include population and tumor characteristics, patient reconstructive outcomes, including locoregional, regional, and distant metastases; other variables, among nipple–areola complex necrosis and infection were collected. Results: The complications detected were considered as “early” within 1 month later the nipple-sparing mastectomy or “late” after this time. The overall complications rate (early and late) and the overall survival and the relapses detected by this study were comparable with those reported in the literature. In order to identify factors that correlate with complications, either early or later, it has been processed an evaluation of the univariate analysis showing adjuvant chemotherapy as the only predictive factor for late complications, while we encountered no predictors for early complications. Conclusions: The present study adds to the data already present in literature, demonstrating that the nipple-sparing mastectomy is a safe procedure, providing good oncological and aesthetic results in patients carefully selected.

Abstract
Most diaphragmatic ruptures are due to the traumatic or penetrating injury, while the spontaneous diaphragmatic rupture is considered uncommon. The spontaneous transdiaphragmatic hernia is a consequence of violent coughing, vomiting that increase the thoracoabdominal pressure causing the diaphragmatic rupture. Even rarer is the concomitant prolapse of abdominal viscera into the thoracic subcutis through the chest wall, a condition known as spontaneous transdiaphragmatic intercostal hernia. Herein, we present a rare case of spontaneous transdiaphragmatic intercostal hernia presenting as a thoracoabdominal emergency.

Abstract
AIM: To define NGF (nerve growth factor) and its high-affinity receptor trkANGF presence and distribution in fibrotic liver and in HCC, and to verify if NGF might have a role in fibrosis and HCC.
METHODS: Intracellular distribution of NGF and trkANGF were assessed by immunohistochemistry and immuno-electron microscopy in liver specimens from HCC, cirrhosis or both. ELISA was used to measure circulating NGF levels.
RESULTS: NGF and trkANGF were highly expressed in HCC tissue, mainly localized in hepatocytes, endothelial and some Kupffer cells. In the cirrhotic part of the liver they were also markedly expressed in bile ducts epithelial and spindle-shaped cells. Surprisingly, in cirrhotic tissue from patients without HCC, both NGF and trkANGF were negative. NGF serum levels in cirrhotic and/or HCC patient were up to 25-fold higher than in controls.
CONCLUSION: NGF was only detected in liver tissue with HCC present. Intracellular distribution suggests paracrine and autocrine mechanisms of action. Better definition of mechanisms may allow for therapeutic and diagnostic/prognostic use of NGF.

Abstract
Deep fibromatosis is a rare locally aggressive but not metastasizing proliferation. Intra-abdominal fibromatosis (IAF) occurs either in association with Gardner's syndrome or as a sporadic event and presents in most cases differential diagnostic problems with myofibroblastic or fibroblastic tumors, characterized by a more aggressive biological behaviour such as gastrointestinal stromal tumors (GISTs). In absence of loco-regional and/or distant metastasis differential diagnosis may be difficult and represents a topical issue, since it influences treatment choice. We describe the case of a patient with sporadic IAF in which the tumor locally involved the mesentery and presented no loco-regional and distant spread. On histology, some morphological features of the neoplasm were in common with a GIST. Definitive diagnosis was made, postoperatively, on the basis of immunohistochemical findings.

Abstract
Breast carcinoma remains the most common malignancy in women in western countries. The principal sites of metastases are the regional lymph nodes, liver, lung and bone; unusual sites of metastases are very rare. Infiltrating ductal carcinoma is the most common histological subtype (about 80%) as compared to lobular carcinoma (7-20%), which metastasizes more frequently to unusual sites. An 80-year-old female patient was submitted to resection of an infiltrating ductal carcinoma (stage I). After 4 years, the presence of a pelvic mass in the absence of local, distant or lymph node recurrence was found. Resection of the mass was performed. The pathological and immunohistochemical examination revealed a metastatic carcinoma compatible with a mammalian origin. After 36 months of follow-up the patient is alive and disease-free. Considering the age of the patient, the good performance status, the absence of other sites of relapse and the large size of the mass, surgery was performed. Surgery remains the only valid option when recurrence produces abdominal complications. In the absence of randomized prospective studies, however, we do not know whether this is always the correct therapeutic strategy.

Abstract
Merkel cell carcinoma is an aggressive skin cancer, with a significant incidence of locoregional lymphnode involvement, which requires timely diagnosis, adequate staging and aggressive therapy based essentially on surgical procedures. The aim of this study is to report our experience and to compare our results with literature findings, in order to discuss the role of the procedures adopted and their influence on prognosis. From July 1995 to April 2005, 14 patients were treated and followed-up for MCC in the National Cancer Institute of Naples. Tumor location was: buttocks (43%), extremities (36%) head (7%), unknown (14%). There were 7 Stage I, 5 Stage II and 2 Stage III patients. Surgical treatment consisted in wide excision (WE) in Stage I cases, WE and regional lymphadenectomy followed by radio- or chemo-therapy in Stage II and combined surgical and pre- and post-operative medical treatments in Stage III. Overall disease specific survival rate was 64% (median follow up 44 months). Recurrence occurred in 86% of Stage I and 20% of Stage II patients and involved, in 83.3% of Stage I patients, the lymph nodal draining basin. The treatment of recurrence implied surgery and radio or radiochemotherapy. Overall survival rate of recurrent patients was 57% (median follow-up 37.2 months). Due to the particular lymphotrophism of MCC, major care should be set on investigation and treatment of tumor lymph nodal draining basin. As long as the disease remains surgically manageable the prognosis for patients with MCC is favourable. The role of radio and chemotherapy is not yet assessed.

Abstract
The presence of metastatic lesions confined to the caudate lobe (CL or segment I) is quite a rare event. Even more rare is the decision to perform an isolate CL resection. Segmental resection in the liver is justified by the evidence that primary and secondary lesions, in early stage, are confined to the originating segment, and therefore a segmentectomy can be considered for the CL as well. Anatomy of the CL was deeply studied through the years since the surgical approach to this liver segment requires a detailed knowledge of its surgical anatomy and only after 1985 the surgical technique for CL isolate resection was established. We report our experience with 1 case of isolate colo-rectal metastasis confined to the caudate lobe and describe the surgical technique employed.

Abstract
Cutaneous squamous cell carcinoma (SCC) is, in its most frequent presentation, a moderately aggressive neoplastic disease. It can, however, present in a moltitude of clinico-pathological variants, some of which are characterized by a more malignant attitude. It is important to determine which tumors, among the various histophenotypes, are high risk in order to establish the appropriate treatment and follow-up. Histologic subtype has been considered as a possible variable in determining the prognosis of cutaneous SCC. We report our experience with 3 cases of peculiar variants of cutaneous SCC.

Abstract
Merkel cell carcinoma (MCC) is a rare, malignant skin cancer, exhibiting neuroendocrine differentiation, with a significant incidence of locoregional lymph nodal involvement (40%-73%). The accepted staging system classifies MCC as: stage I, localized skin disease; stage II, regional lymph node disease; stage III, metastatic disease. The clinical differentiation of stage I and II patients is difficult and understaging is frequent. Surgery, as first approach, represents the leading treatment for this neoplasm and, depending on stage consists in: local wide excision for stage I patients and local excision and lymphadenectomy for stage II. In our experience, lymphadenectomy, included in the initial treatment of all stage II patients, seemed to influence positively the prognosis. In comparing stage related recurrence and survival rates the results we obtained were better in stage II patients, where lymphadenectomy was included in the initial treatment than in stage I subjects, who received local excision alone as first treatment and lymphadenectomy as secondary treatment for nodal recurrence (overall recurrence rate 86% vs 20%, survival rate 71% vs 80% in stage I vs stage II patients). The performance of lymphadenectomy for stage I MCC could be reconsidered both for a more reliable staging of the disease and for a positive impact on recurrence and survival rates.

Abstract
Intraoperative radiofrequency (RF) ablation has recently become a valid procedure in the treatment of liver primary or secondary malignancies in selected cases. This procedure can be used alone or in association with surgery in treating lesions not considered for curative surgery. Heat damage of the main bile ducts represents nowadays a limitation in the use of radiofrequency ablation of hepatic lesions. Up to now, in tumors proximal to a main bile duct or to the biliary bifurcation this procedure has been contraindicated. In order to preserve these structures from heat damage, a new technique consisting of intraductal cooling of the bile ducts has recently been introduced. We report a case of successful experience with this technique.

Abstract
Isolated pancreatic metastatic melanoma is a rare occurrence. Even more rare is the surgical treatment of this lesion. However, considering the lack of effective systemic treatment and the decreasing morbidity and mortality rates of pancreatic resections in specialized centers, selected patients, especially if symptomatic, may be considered for surgical resection to achieve good palliation or improve survival. We performed a pancreaticoduodenectomy in a patient with a bleeding pancreatic metastasis from cutaneous melanoma excised 10 years before and reviewed the recent literature.

Abstract
PURPOSE The aim of this study was to evaluate the opportunity of surgical treatment in terms of liver resection or liver transplantation in HIV positive patients affected by an end stage liver disease that referred to our liver unit. METHODS Among 1350 outpatients who referred to our liver unit from January 2002 to September 2003, thirty-two (2,4%) were HIV positive. The routes of transmission of the viral infection, the related co-infections and the underlying liver disease were recorded. The therapeutic pathway was analysed. The kind and the duration of the surgical procedures were assessed. RESULTS Fourteen (44%) of these thirty-two patients were not suitable for surgical treatment. Surgery was planned in 9 of 32 HIV positive patients (28%). Four patients (12%) were submitted to liver resection and OLT was performed in five patients (15%). Hepatocellular Carcinoma was present in 4 (44%) of the HIV positive patients considered for surgery. CONCLUSIONS In conclusion in our centre the 28% of HIV positive out patients had the opportunity to receive a surgical treatment. The candidate to this surgery is mostly young, HCV and/or HBV coinfected and affected by HCC in 44% of cases.

Abstract
Liver transplantation for malignancies still remains a controversial issue. There is concern for tumour recurrence, poor results and waste of organs, which in the sitting of organ shortage would penalize patients with non-malignant disease. Many centers worldwide perform liver transplantation (OLT) for hepatocellular (HCC) carcinoma associated with liver cirrhosis; the results in these cases are similar to those of patients transplanted for other indications. On the contrary are very few the centers that perform OLT for tumour other than HCC. This reflects that tumours other than HCC are less common and survival is poor compared to patients transplanted for non-malignant disease. Acceptable indications for OLT in case of tumours other than HCC are liver metastases from neuroendocrine tumours and epithelioid emangio-endothelioma. However should be kept in mind that OLT may offer the sole opportunity to cure the tumour and the underlying disease in some patients while providing meaningful palliation for others. At the present the overall experience with OLT for tumours other than HCC is still not significant and the results are discouraging. There is no evidence that OLT is beneficial for non-HCC tumours. Hopefully for the next future new adjuvant and neoadjuvant therapies combined with OLT would provide improved survival. Nevertheless, long-term survivors continue to be reported suggesting that OLT may be beneficial in individual selected cases with non-HCC tumour.

Abstract
OLT in HIV infected patients still remains a challenging option requiring a careful monitoring of patients for HCV reinfection, drug interactions and antiretroviral toxicity. Severe adverse events due to HAART have been already reported for post exposure prophylaxis in HIV infected patients. Here we report a case of liver graft toxicity related to HAART in a HIV-HCV co-infected patient (46 yrs-male) with associated a small HCC transplanted with a marginal liver graft. The patient had pre-OLT plasma HIV 1-RNA levels undetectable and CD4+ T-cell count of > 200 cells/microL for 6 months. At day 2 a severe graft dysfunction was observed (AST 1570 U/L, ALT 2180 U/L, BIL tot 8.3 mg/dL, BIL Dir 6.6 mg/dL and PT 35%--INR 2.5). Doppler scan showed hepatic artery always patient. Later the postoperative in-hospital course was complicated by tense ascites and severe cholestasis. Serum bilirubin reached 42 mg/dL in day 12. Hypertransaminasemia ended at day 15 while cholestasis ended after 46 days. Tacrolimus was reintroduced at day 7. A liver biopsy 10 after OLT showed severe intrahepatic cholestasis, centrolobular necrosis and macrovesicular steatosis (30%). The patient was discharged 48 days after OLT with good liver function. After seven months HIV-RNA is still undetectable and HAART has not been restarted. We believe that the early complications we observed may be attributed to a sudden increase in plasma concentration of antiretroviral drugs secondary to drug redistribution from peripheral tissues and hepatic clearance deficiency after OLT. Although a pre-OLT withdrawal of HAART seems unjustified a delayed re-introduction of HAART or the use of less hepatotoxic drugs may be advisable.

Abstract
We describe a modification of Belghiti's "liver hanging maneuver" applied to the last phase of hepatectomy during OLT with IVC preservation. The proposed maneuver provides a better exposition of the suprahepatic veins allowing an ortogonal clamping of the suprahepatic confluence and avoiding caval clamping. It allows, moreover, an increase of venous surface available for the anastomosis that results wider and easier to perform. This provides a large outflow anastomotic cloaca and prevents outflow problems of the graft.

Abstract
Adrenal metastases from Malignant Melanoma (MM) represent a debated therapeutical problem particularly in the case of disseminated disease. Surgical treatment, however, seems to be able to provide improvement on survival. Laparoscopic adrenalectomy is considered a gold standard procedure in benign adrenal disease but its value in malignancy, in terms of oncological effectiveness, is not known. A case of bilateral adrenal malignant melanoma metastases is reported. The patient, affected by superficial spreading melanoma of the right foot, eleven years after the primary developed a right adrenal metastasis. The relapse was treated by laparoscopic right adrenalectomy. One year later the patient had a new metastasis in the left adrenal gland and was submitted to laparoscopic left adrenalectomy. The two step laparoscopic bilateral adrenalectomy showed to be quite easy to perform, providing a complete removal of the whole glands, without adrenal tissue crushing and without neoplastic tissue dissemination in abdominal cavity. The postoperative course was excellent and the patient was discharged within about 72 hours after the two procedures. In literature only few reports indicate the feasibility of laparoscopic adrenalectomy for malignancy. In the reported case of malignant melanoma metastasis, minimally invasive adrenalectomy was very satisfactory and the good results obtained suggest its routine use.

Abstract
BACKGROUND/AIMS Purpose of this study is to define the effectiveness of surgical resection of liver metastases from operated breast cancer. METHODOLOGY Nineteen patients underwent surgical exploration to resect liver metastases from previously operated breast carcinoma. Seventeen patients were resected: 15 patients had unique metastases and were submitted to a wedge liver resection while 2 had multiple lesions; in these cases a V-VI segmentectomy and a right hepatectomy was required. After liver resection 11 patients received chemotherapy, 2 chemotherapy plus hormone therapy, 2 hormone therapy alone and in the remaining 2 no adjuvant treatment was done. RESULTS Postoperative mortality was nil and morbidity consisted of 1 subphrenic abscess and 1 pleural effusion. Actuarial 5-year survival rate was 46%. Eight patients are still alive, 7 of whom are disease-free. Nine patients died for neoplastic progression. CONCLUSIONS Surgical resection of liver metastases from breast cancer seems to be able to improve long-term survival in selected patients with unique and isolated lesions especially in association to systemic chemotherapy and hormone therapy.

Abstract
Aim of this study is to define feasibility and effectiveness of the transhiatal esophagogastric resection in cardia adenocarcinoma. From 1981 to 2001, we submitted to surgery 85 patients affected by cardia adenocarcinoma. Since 1994, 34 patients, in consideration of clinical, anatomosurgical (Siewert II-III) and pathologic (T1-3, cN mediastinal negative) findings, underwent transhiatal esophagogastric resection according to Pinotti's technique. This consisted in the midline opening of the central tendon of the diaphragm, ligature and section of the left inferior phrenic vessels, exposure and anterior retraction of the pericardium. The approach allowed in all cases a satisfactory esophageal mobilization and a good dissection of the inferior mediastinal structures avoiding thoracotomy. Postoperative complications were observed in 8 patients (24%). In 4 cases the complications were medical (11.8%) and in 4 cases surgical (11.8%). Death occurred in 4 cases (11.8%): in 3 patients (8.8%) for local complications (2 anastomotic leaks and 1 hemorrage) and in 1 (2.9%) for cardiac failure. The 26 non complicated cases had an uneventful postoperative course and were discharged 12 days after surgery. Middle and long term results were evaluated in terms of locoregional recurrence rate and actuarial survival. At 1 and 2 years locoregional recurrence occurred in 8.8% and 11.8% of cases respectively. Five-year overall survival was 22.5%. In selected cases (Siewert type II-III, T1-3 tumors with clinically negative mediastinal lymphnodes) the procedure in study appears technically feasible, it provides a satisfactory volume of esophageal exeresis and an adequate extension of mediastinal lymphadenectomy, representing a safe and effective alternative to thoracotomy in cardia cancer surgery.

Abstract
The authors report their data on 344 cases of small-cell lung cancer treated according to indications with combined chemoradiotherapy and in selected cases with surgical intervention. In patients with limited disease, the results of pharmacologic therapy significantly improve the prognosis only in association with surgery. The role of surgery has been reappraised in the treatment of small-cell lung cancer which appears, nowadays, multidisciplinary.

Abstract
Data from a series of 181 patients subjected to long-term follow-up after surgical resection for non-small cell stage I and II lung cancer were analyzed to evaluate the statistical incidence and the prognostic factors of recurrence. The recurrence rate/year was particularly high in the first 2 years after surgery: the 2-year recurrence rate was 35.1% in stage I tumors and 51.8% in stage II, whereas the 5- and 7-year recurrence rates were 46.1 and 55.9% and 65.8 and 70.7%, respectively, for the same groups. Recurrences were observed more frequently in non-epidermoid carcinomas with multiple nodules (100% at 5 years) and in carcinomas classified as stage II (70.7% at 5-7 years), particularly when defined as adenocarcinoma (100% at 3 years). In the overall recurrence rate we observed no significant difference dependent on the type of resection even though limited segmental or wedge resection appeared to be related to a higher risk rate (true recurrence rate ratio: 0.6). Over two-thirds of the first observed recurrences were located at a distant site, with a slightly higher incidence of non-epidermoid carcinoma (72.5%). Isolated local recurrence mostly occurred in epidermoid carcinoma (47.6%). The most frequent sites of recurrence were the brain, bone and mediastinum. On multivariate analysis, independently significant adverse prognostic factors regarding the recurrence incidence were: tumor size greater than 3 cm, bronchial or hilar lymph node involvement, tumor histologically defined as adenocarcinoma, and the presence of satellite nodules.
