Abstract
Super-extended (D2plus) lymphadenectomy after chemotherapy has been reported in only a few studies. This retrospective study evaluates survival outcomes in a Western cohort of locally advanced or oligometastatic gastric cancer patients who underwent D2plus lymphadenectomy after neoadjuvant chemotherapy. A total of 97 patients treated between 2010 and 2022 were included. Of these, 62 had clinical stage II/III disease, and 35 had stage IV disease. Most patients (65%) received preoperative DOC/FLOT chemotherapy. The mean number of lymph nodes harvested was 39. Pathological positive nodes in the posterior/para-aortic stations occurred in 17 (17.5%) patients. Lymphovascular invasion, ypN stage, clinical stage, and perineural invasion were predictive factors for positive posterior/para-aortic nodes. Postoperative complications occurred in 21 patients, whereas severe complications (grade III or more) occurred in 9 cases (9.3%). Mortality rate was 1%. Median overall survival (OS) was 59 months (95% CI: 13-106), with a five-year survival rate of 49 ± 6%; the five-year OS after R0 surgery was 60 ± 7%. In patients with positive posterior/para-aortic nodes, the median OS was 15 months (95% CI: 13-18). D2plus lymphadenectomy after chemotherapy for locally advanced or oligometastatic gastric cancer is feasible and associated with low morbidity/mortality rates. The incidence of pathological metastases in posterior/para-aortic nodes is not negligible even after systemic chemotherapy, with poor long-term survival.

Abstract
BACKGROUND We aimed at evaluating the temporal trend of drug-resistance and APOBEC editing from HIV-DNA genotypic resistance tests (GRT) in virologically suppressed individuals. MATERIAL AND METHODS Major resistance mutations (MRM), genotypic susceptibility score (GSS) for the current regimen and APOBEC-related mutations (APO-M) were evaluated. Potential changes in trends of MRM and APO-M over-time were assessed and predictors of MRM detection or sub-optimal GSS (GSS<2) at HIV-DNA-GRT were estimated through logistic regression analyses. RESULTS Among the 1126 individuals included, 396 (35.2%) harboured at least one MRM (23.4% to NRTI, 18.8% to NNRTI, 7.7% to PI and 1.4% to INSTI [N=724]); 132 (12.3%) individuals showed a GSS <2. APO-M and stop codons were found in 229 (20.3%) and 105 (9.3%) individuals, respectively. APO-DRMs were found in 16.8% of individuals and were more likely observed in those individuals with stop codons (40.0%) compared to those without (14.4%, P<0.001). From 2010 to 2021 no significant changes of resistance or APO-M were found. Positive predictors of MRM detection at HIV-DNA GRT were drug abuse, subtype B infection, and a prolonged and complex treatment history. Perinatal infection and having at least 2 stop codons were associated with a current suboptimal regimen. CONCLUSIONS In virologically suppressed individuals, resistance in HIV-DNA and the extent of APOBEC editing were generally stable in the last decade. A careful evaluation of APOBEC editing might be helpful to improve the reliability of HIV-DNA GRT. Further investigations are required to understand how to apply the estimation of APOBEC editing in refining genotypic evaluation.

Abstract
HIV and hepatitis B virus (HBV) coinfection is relatively common. Initiation of antiretroviral therapy (ART) in people with HIV (PWH) causes a progressive restoration of cell-mediated immune functions. In the presence of overt or occult coinfections, immune restoration might lead to immune reconstitution inflammatory syndrome (IRIS). Here, we describe the clinical, immunological, virological, and histological characterization of a case of HBV-related IRIS hepatitis in a PWH after ART initiation. A liver biopsy was performed during HBV-related IRIS hepatic flare, and liver samples were analyzed through immunohistochemistry and molecular techniques, with the assessment of intrahepatic HBV-DNA, covalently closed circular DNA, and HBV pregenomic RNA through a droplet digital polymerase chain reaction system. Immune activation and senescence were also longitudinally assessed. In this clinical case, the hepatic flare occurred 6 weeks after ART initiation with a therapeutic regimen including tenofovir alafenamide (TAF) and emtricitabine (FTC). The episode was self-limiting, characterized by hyperactivation of peripheral blood CD4+ and CD8+ T-lymphocytes, and resolved without ART discontinuation, leading to the achievement of HBsAg seroconversion (HBsAg-/HBsAb+) and HBV-DNA plasma undetectability. Notably, hyperactivation of the immune system plays a pivotal role in promoting the control of HBV replication, thus triggering the achievement of HBsAg seroconversion during treatment with TAF/FTC.

Abstract
Objectives To determine the reproducibility of the National Comprehensive Cancer Network (NCCN) resectability status classification for pancreatic cancer. Background The NCCN classification defines 3 resectability classes (resectable, borderline resectable, locally advanced), according to vascular invasion. It is used to recommend different approaches and stratify patients during clinical trials. Methods Prospective, multicenter, observational study (trial ID: NCT03673423). Main outcome measure was the interobserver agreement of tumor assignment to different resectability classes and quantification of vascular invasion degrees. Agreement was measured by Fleiss' k (k = 1 perfect agreement; k = 0 agreement by chance). Sixty-nine computed tomography (CT) scans of pathologically confirmed pancreatic adenocarcinoma were independently reviewed in a blinded fashion by 22 observers from 11 hospitals (11 surgeons and 11 radiologists). Rating differences between surgeons or radiologists and between hospitals with different volumes (≥60 or <60 resections/year) were assessed. Results Complete agreement among 22 observers was recorded in 5 CT scans (7.2%), whereas 25 CT scans (36.2%) were variously assigned to all 3 resectability classes. Interobserver agreement varied from fair to moderate (Fleiss' k range: 0.282-0.555), with the lowest agreement for borderline resectable tumors. Assessing vascular contact ≤180° had the lowest agreement for all vessels (k range: 0.196-0.362). The highest concordance was recorded for venous invasion >180° (k range: 0.619-0.756). Neither reviewers' specialty nor hospital volume influenced the agreement. Conclusions There is high variability in the assignment to resectability categories, which may compromise the reliability of treatments recommendations and the evidence of trials stratifying patients in resectability classes. Criteria should be revised to allow a reproducible classification.

Abstract
OBJECTIVES To evaluate the prevalence and therapeutic relevance of drug resistance among isolates from ART-experienced HIV-1-infected patients over the past two decades in Italy. METHODS Dynamics of resistance to one, two and three or more antiretroviral classes were evaluated from 1999-2018. Virological success (VS) after the latest therapy switch was evaluated according to cumulative class resistance and cumulative genotypic susceptibility score (Stanford HIV_DB algorithm). RESULTS Among 13 663 isolates (from 6739 patients), resistance to at least one drug class decreased sharply from 1999 to 2010 (≤2001, 84.6%; 2010, 43.6%; P < 0.001), then remained relatively constant at ∼40% during 2010-18, with the proportion of resistance to three or more classes also stable (∼5%). After 2008, integrase inhibitor resistance slightly increased from 5.6% to 9.7% in 2018 and contributed to resistance, particularly in isolates with resistance to three or more classes (one class, 8.4%; two classes, 15.3%; three or more classes, 34.7%, P < 0.001). Among 1827 failing patients with an available follow-up, by 1 year after genotype-guided therapy start the probability of VS was 87.6%. Patients with cumulative resistance to three or more classes and receiving a poorly active regimen showed the lowest probability (62.6%) of VS (P < 0.001) compared with all other patients (≥81.8%). By Cox regression analysis, cumulative MDR and receiving poorly active antiretroviral regimens were associated with a lower hazard of VS compared with those without resistance. CONCLUSIONS A dramatic drop of HIV-1 drug resistance at failure has been achieved over the last two decades in Italy; resistance to three or more classes is low but present among currently failing patients. Its management still requires a rational and careful diagnostic and therapeutic approach.

Abstract
Since its discovery in 1958, Burkitt lymphoma (BL) has been extensively studied and has become a model for tumorigenesis, but its pathogenesis has not been completely explained and understood yet. The aim of this review was to summarize the current knowledge about BL and, in particular, to discuss the role of miRNAs in its pathogenesis and their possible use as diagnostic and prognostic indicators. The impact of viral-encoded miRNAs is also discussed, with the Epstein–Barr infection being almost invariably detected in the endemic variant of this tumor.

Abstract
Primary osteosarcoma of the kidney is a very rare neoplasm with a very poor prognosis and unclear histogenesis. Only 20 cases have been reported in the literature. It has a strong tendency to recur locally and spread to distant sites. We present the clinical case of a 79-year-old man affected by a primary osteosarcoma of the kidney presenting with substantial retroperitoneal tumor hemorrhage. Laparotomy revealed a massive retroperitoneal hematoma due to a bleeding large stony renal mass with multiple bizarre calcifications. The diagnosis of primary renal osteosarcoma was made on the basis of hematoxylin-eosin staining and confirmed by electron microscopy. Hematoma drainage and radical nephrectomy were performed. To our knowledge this is the first case of bleeding renal osteosarcoma reported in the literature. The most important clinical findings, the pathogenesis and the treatment modalities of this rare neoplasm are discussed.

Abstract
AIM: To evaluate the role of computed tomography (CT) for diagnosing traumatic injuries of the pancreas and guiding the therapeutic approach.
METHODS: CT exams of 6740 patients admitted to our Emergency Department between May 2005 and January 2013 for abdominal trauma were retrospectively evaluated. Patients were identified through a search of our electronic archive system by using such terms as “pancreatic injury”, “pancreatic contusion”, “pancreatic laceration”, “peri-pancreatic fluid”, “pancreatic active bleeding”. All CT examinations were performed before and after the intravenous injection of contrast material using a 16-slice multidetector row computed tomography scanner. The data sets were retrospectively analyzed by two radiologists in consensus searching for specific signs of pancreatic injury (parenchymal fracture and laceration, focal or diffuse pancreatic enlargement/edema, pancreatic hematoma, active bleeding, fluid between splenic vein and pancreas) and non-specific signs (inflammatory changes in peri-pancreatic fat and mesentery, fluid surrounding the superior mesenteric artery, thickening of the left anterior renal fascia, pancreatic ductal dilatation, acute pseudocyst formation/peri-pancreatic fluid collection, fluid in the anterior and posterior pararenal spaces, fluid in transverse mesocolon and lesser sac, hemorrhage into peri-pancreatic fat, mesocolon and mesentery, extraperitoneal fluid, intra-peritoneal fluid).
RESULTS: One hundred and thirty-six/Six thousand seven hundred and forty (2%) patients showed CT signs of pancreatic trauma. Eight/one hundred and thirty-six (6%) patients underwent surgical treatment and the pancreatic injures were confirmed in all cases. Only in 6/8 patients treated with surgical approach, pancreatic duct damage was suggested in the radiological reports and surgically confirmed in all cases. In 128/136 (94%) patients who underwent non-operative treatment CT images showed pancreatic edema in 97 patients, hematoma in 31 patients, fluid between splenic vein and pancreas in 113 patients. Non-specific CT signs of pancreatic injuries were represented by peri-pancreatic fat stranding and mesentery fluid in 89% of cases, thickening of the left anterior renal fascia in 65%, pancreatic ductal dilatation in 18%, acute pseudocyst/peri-pancreatic fluid collection in 57%, fluid in the pararenal spaces in 45%, fluid in transverse mesocolon and lesser sac in 29%, hemorrhage into peri-pancreatic fat, mesocolon and mesentery in 66%, extraperitoneal fluid in 66%, intra-peritoneal fluid in 41% cases.
CONCLUSION: CT represents an accurate tool for diagnosing pancreatic trauma, provides useful information to plan therapeutic approach with a detection rate of 75% for recognizing ductal lesions.

Abstract
INTRODUCTION Carbon dioxide (CO2) therapy refers to trans-cutaneous or sub-cutaneous administration of CO2 for therapeutic purposes, and recent studies have pointed out that it produces a vasodilation effect after it is locally injected, which helps amplify the reconstructive potentiality of an expanded-muscle flap. MATERIALS AND METHODS Thirty male Wistar rats, weighting between 350 and 400 g, were randomly divided into three groups of 10. In the first group, single intra-operative rapid expansion was carried out under the right latissimus dorsi muscle. In the second group, for five days prior to surgery, a pre-treatment with intramuscular injections of CO2 was performed. The third group served as controls. For each group, the latissimus dorsi muscle was fixed as soon possible after mice died, and ultrathin sections of it examined with transmission electron microscope. RESULTS In the treated group, the majority of expanded muscles showed a normal striation pattern, whereas a few fibers showed mild disorganization of the myo-filaments in the sarcomeres, which appeared overstretched (average 2.37 µm). CONCLUSIONS This evidence could demonstrate a greater capacity of muscle recovery after treatment by CO2 expansion.

Abstract
Background Recent evidence suggests that lipid pathway is altered in many human tumours. In Burkitt lymphoma this is reflected by the presence of lipid droplets which are visible in the cytoplasm of neoplastic cells in cytological preparations. These vacuoles are not identifiable in biopsy section as lipids are “lost” during tissue processing. Methods and Results In this study we investigated the expression of genes involved in lipid metabolism, at both RNA and protein level in Burkitt lymphoma and in other B-cell aggressive lymphoma cases. Gene expression profile indicated a significant over-expression of the adipophilin gene and marked up-regulation of other genes involved in lipid metabolism in Burkitt lymphoma. These findings were confirmed by immunohistochemistry on a series od additional histological samples: 45 out of 47 BL cases showed strong adipophilin expression, while only 3 cases of the 33 of the not-Burkitt lymphoma category showed weak adipophilin expression (p<0.05). Conclusions Our preliminary results suggest that lipid metabolism is altered in BL, and this leads to the accumulation of lipid vacuoles. These vacuoles may be specifically recognized by a monoclonal antibody against adipophilin, which may therefore be a useful marker for Burkitt lymphoma because of its peculiar expression pattern. Moreover this peptide might represent an interesting candidate for interventional strategies.

Abstract
Burkitt lymphoma is endemic in the Equatorial Belt of Africa, its molecular hallmark is an activated, MYC gene mostly due to a chromosomal translocation. Especially in its endemic clinical variant, Burkitt lymphoma is associated with the oncogenic Epstein-Barr virus (EBV), and holoendemic malaria acts as an amplifier. Environmental factors may also cooperate in Burkitt lymphomagenesis in the endemic regions, such as plants used as traditional herbal remedies. Euphorbia tirucalli, a plant known to possess EBV-activating substances, has a similar geographical distribution to endemic Burkitt's Lymphoma and is used as a hedge, herbal remedy and toy in the Lymphoma BeltI. In this study we aimed at determining if exposure to Euphorbia tirucalli could contribute to lymphomagenesis, and at which extent. Lymphoblastoid and cord blood-derived cell lines were treated with plant extracts, and the expression of EBV-coded proteins was checked, to assess EBV reactivation. The occurrence of chromosomal translocations was then investigated by FISH. Our preliminary results suggest that E. tirucalli is able to reactivate EBV and determine chromosomal alterations, which leads to c-MYC altered expression. The existence of genomic alterations might determine the accumulation of further genetic alteration, which could eventually lead to a transformed phenotype.

Abstract
Histopathological and immunohistochemical findings on tissue microarrays, overall survival (OS), disease-free survival (DFS) and incidence of relapses (R) were recorded and statistically analyzed in 289 breast cancers. A higher R and a shorter DFS were significantly related to larger tumors, lymph node invasion, higher tumor grade, absence of estrogen receptors (ER), triple negative tumors, and presence of lymphovascular invasion (LVI). Longer OS was observed to be significantly associated with smaller tumor size (T), lymph node negativity, lower tumor grade, absence of LVI, lower Mib-1 expression and with the presence of ER. At multivariate analysis, only T for DFS and lymph node status and triple negativity either for DFS or OS had independent prognostic value. In the 194 lymph node-negative women DFS and OS were inversely related to tumor grade, absence of ER, Mib-1 expression in more than 15% of neoplastic cells and, only for DFS, presence of LVI. In the 95 lymph node-positive the number of involved nodes was the most discriminating parameter either for DFS or OS; T, Her-2 status and presence of LVI were significantly related to DFS. ER negativity was related to higher grade, progesterone receptors (PR) negativity, Her-2 negativity, hence to triple negativity, to basal-like type, Mib-1expression over 15% of neoplastic cells. Her-2 positivity was related to higher grade, ER positivity and PR positivity. Basal-like type was not an independent prognosticator, while triple negative type has a significant relation to shorter OS. The Nottingham prognostic index accurately identifies prognostic groupings and Mib-1 expression and ER signaling are the key biological predictors even in single cases.

Abstract
Primary small-cell carcinoma (SmCC) of the stomach is a rare neoplasm with a poor prognosis and unclear histogenesis: to date, only 50 cases, including ours, have been reported in the literature. In the World Health Organization gastrointestinal tumours' classification, SmCC of the stomach has been recognized as an 'independent entity affecting the stomach'. In this paper, the authors present a clinical case and the surgical treatment of an adult with a SmCC of the stomach associated with gastric adenocarcinoma. After laparotomy, a large neoplasm with locoregional extension and multiple liver metastases were found. A palliative resection, subtotal gastrectomy, was performed, followed by systemic and intra-hepatic chemotherapy: computed tomography scan demonstrated a marked response, but the patient died 15 months after the operation. A review of the literature showed that the diagnosis of gastric SmCC is based on immunohistochemical findings. Our experience confirmed the high aggressiveness of this neoplasm, which is generally diagnosed in advanced stage and is unresponsive to chemotherapy, but the combined use of systemic and intra-hepatic chemotherapy shows an acceptable result in a palliative care perspective.

Abstract
BACKGROUND CD4+CD25+FOXP3+ regulatory T cells (Tregs) are thought to induce immunotolerance in melanoma. They have not yet been investigated in the entire spectrum of melanocytic cutaneous lesions within a tumour site. OBJECTIVES To evaluate CD4+CD25+FOXP3+ Tregs among tumour-infiltrating lymphocytes in cutaneous melanocytic lesions. METHODS We analysed 128 lesions (10 benign junctional common naevi, 10 benign compound common naevi, 10 compound Spitz naevi, 10 junctional atypical naevi, 20 compound atypical naevi, 20 radial growth phase melanomas, 30 vertical growth phase melanomas and 18 melanoma metastases). Tregs were identified by CD25-FOXP3 double immunostains. RESULTS This study indicates that CD4+/CD25+FOXP3+ Tregs are present in all groups of lesions. Junctional atypical naevi, compound atypical naevi and radial growth phase melanomas showed the highest percentages of CD4+CD25+FOXP3+ Tregs (junctional atypical naevi vs. junctional common naevi, compound common naevi, compound Spitz naevi, melanoma metastases: P < 0.0001; junctional atypical naevi vs. vertical growth phase melanomas: P = 0.001; compound atypical naevi vs. junctional common naevi, compound common naevi: P < 0.0001; compound atypical naevi vs. compound Spitz naevi, melanoma metastases: P = 0.002; compound atypical naevi vs. vertical growth phase melanomas: P = 0.02; radial growth phase melanomas vs. junctional common naevi, compound common naevi, compound Spitz naevi, melanoma metastases: P < 0.0001; radial growth phase melanomas vs. vertical growth phase melanomas: P = 0.008). CONCLUSIONS The strong prevalence of CD25+FOXP3+ Tregs both in junctional and compound atypical naevi and radial growth phase melanomas, suggests that they induce immunotolerance early during melanoma genesis, favouring melanoma growth. Their evaluation within a tumour site could be useful for prognostic and therapeutic purposes.

Abstract
Beclin 1 is is an autophagy gene, the role of which as a tumour suppressor has recently been recognized in a few studies. We examined the expression of Beclin 1 protein in 212 primary human brain tumours, including 97 high-grade glial tumours, 29 low-grade glial tumours, 4 grade III meningiomas, 19 grade II meningiomas, 52 grade I meningiomas, and 11 medulloblastomas. In 94 cases, including 56 glial tumours, 35 meningiomas, and 3 medulloblastomas we also assessed Beclin 1 mRNA expression by real-time RT-PCR. In most high-grade astrocytic, ependymal neoplasms and atypical meningiomas we found a decrease of cytoplasmic protein expression that was, instead, high in the majority of low-grade tumours and in medulloblastomas. The expression level of Beclin 1 mRNA was significantly lower in glioblastomas than in grade II (p=0.04) and grade I (p=0.01) astrocytomas; in grade III than in grade I astrocytomas (p=0.01); in grade II than in grade I meningiomas (p=0.03); and in all glial tumours when compared to all meningiomas (p<0.0001). Cytoplasmic expression is thought to be linked to the functional protein. Our observations are in line with studies that demonstrated decreased expression of Beclin 1 in human breast, ovarian, prostate and ovarian cancer and furtherly support its involvement also in brain tumours, which had previously been demonstrated in a few experimental studies, both in spontaneous and in therapy-induced autophagy. Furthermore, our study suggests possible differences of Beclin 1 involvement and its role among the different histotypes of brain neoplasms. Further studies are needed to highlight Beclin 1 function in tumour suppression and/or in tumour survival through autophagy and other related programmed cell death processes in brain tumours.

Abstract
Three case reports are presented concerning permanent maxillary molars with fusion of two buccal roots. The morphology is peculiar because it is characterized by the mesiobuccal canal merging into the distobuccal canal in their apical one-third. A thorough review of the literature failed to reveal any previously reported description of permanent maxillary molars with this arrangement of canals, with the exception of a recently reported epidemiological study.
