Combined alteration of lamin and nuclear morphology influences the localization of the tumor-associated factor AKTIP.

Background: Lamins, key nuclear lamina components, have been proposed as candidate risk biomarkers in different types of cancer but their accuracy is still debated. AKTIP is a telomeric protein with the property of being enriched at the nuclear lamina. AKTIP has similarity with the tumor susceptibility gene TSG101.

Occult Neck Metastases in Head and Neck Adenoid Cystic Carcinoma: A Systematic Review and Meta-Analysis.

Adenoid cystic carcinoma (AdCC) is a rare tumor whose clinical course is burdened by local recurrence and distant dissemination. Lymph node metastasis is not believed to be common and its clinical impact is controversial. The aim of this study was to determine: (1) the prevalence of occult metastasis at diagnosis in cN0 head and neck AdCC, (2) its prognostic role, and (3) the consequent need to perform elective neck dissection (END).

Topical chlormethine gel in the treatment of mycosis fungoides: A single-center real-life experience and systematic review of the literature.

Gel formulation of chlormethine (CG) has gained a preeminent role among therapies available for mycosis fungoides (MF). To evaluate the frequency of use of CG for MF treatment and to determine the limits and potentialities of CG in a real-world setting. A systematic review of articles published prior to October 2021 was performed.

Fibroblast-Induced Paradoxical PI3K Pathway Activation in PTEN-Competent Colorectal Cancer: Implications for Therapeutic PI3K/mTOR Inhibition.

Purpose: Tumor-microenvironment interactions are important determinants of drug resistance in colorectal cancer (CRC). We, therefore, set out to understand how interactions between genetically characterized CRC cells and stromal fibroblasts might influence response to molecularly targeted inhibitors.

Techniques: Sensitivity to PI3K/AKT/mTOR pathway inhibitors of CRC cell lines, with known genetic background, was investigated under different culture conditions [serum-free medium, fibroblasts' conditioned medium (CM), direct co-culture].

External Validation of a Prognostic Score for Survival in Lung Carcinoids.

Background: A prognostic score including T-dimension, age, histology and lymph node ratio was previously proposed in absence of an external validation dataset. The aim of the current study was to validate the proposed prognostic score using an independent dataset. Methods: Data of patients with lung carcinoids, who underwent surgical resection and lymphadenectomy in five institutions from 1 January 2005 to 31 December 2019, were retrospectively analyzed.

Correlation of somatostatin receptor PET/CT imaging features and immunohistochemistry in neuroendocrine tumors of the lung: a retrospective observational study.

Purpose: To correlate somatostatin receptor (SSTR) and proliferative activity profile (SSTR2, SSTR5, Ki-67) at immunohistochemistry (IHC) with SSTR-PET/CT imaging features in a retrospective series of lung neuroendocrine tumors (NET). Proliferative activity by Ki-67 and F-FDG-PET/CT parameters (when available) were also correlated.

Methods: Among 551 patients who underwent SSTR-PET/CT with Ga-DOTA-somatostatin analogs (SSA) between July 2011 and March 2020 for lung neuroendocrine neoplasms, 32 patients with a confirmed diagnosis of NET were included.

First-Line Osimertinib in Patients with EGFR-Mutant Advanced Non-Small Cell Lung Cancer: Outcome and Safety in the Real World: FLOWER Study.

Background: Osimertinib became the standard treatment for patients with untreated EGFR-mutant advanced non-small cell lung cancer (aNSCLC) following results reported in the phase III randomized FLAURA trial. Because of strict exclusion criteria, patient populations included in pivotal trials are only partially representative of real-world patients.

Methods: We designed an observational, prospective, multicenter study enrolling patients with EGFR-mutant aNSCLC receiving first-line osimertinib to evaluate effectiveness, safety, and progression patterns in the real-world.

Lymphadenectomy for lung carcinoids: Which factors may predict nodal upstaging? A multi centric, retrospective study.

Objective: To investigate risk factors for nodal upstaging in patients with lung carcinoids and to understand which type of lymphadenectomy is most appropriate.

Methods: Data regarding patients with lung carcinoids, who underwent surgical resection and lymphadenectomy in five institutions from January 1, 2005 to December 31, 2019, were collected and retrospectively analyzed. Clinical and pathological tumor characteristics were correlated to analyze lymph node upstaging.

A mesenchymal chondrosarcoma with aberrant nuclear expression of STAT6: a potential diagnostic pitfall.

STAT6 is usually considered to be a very sensitive and specific immunomarker for diagnosis of solitary fibrous tumor (SFT), being a surrogate of the NAB2-STAT6 fusion gene identified in most cases of this tumor. STAT6 expression has also been reported in rare cases of other soft tissue tumors, such as low-grade fibromyxoid sarcoma, myxoid/round cell liposarcoma, dedifferentiated liposarcoma and deep fibrous histiocytoma. The aim of this study was to report, for the first time, a case of mesenchymal chondrosarcoma showing diffuse aberrant immunohistochemical expression of STAT6.

Incidence and clearance of anal high-risk Human Papillomavirus infection and their risk factors in men who have sex with men living with HIV.

HIV-infected men who have sex with men (MSM) display the highest prevalence of anal infection by high-risk Human Papillomaviruses (hrHPVs) and incidence of anal carcinoma. Anal specimens were genotyped by the Linear Array. Incidence and clearance of anal infection by hrHPVs, hrHPVs other than HPV16, low-risk HPVs, and four individual types (6,11,16,18) were estimated using a two-state Markov model.

Efficacy of the BNT162b2 mRNA COVID-19 Vaccine in Patients with Chronic Lymphocytic Leukemia: A Serologic and Cellular Study.

Background: Antibody response following SARS-CoV-2 vaccination is somewhat defective in chronic lymphocytic leukemia (CLL). Moreover, the correlation between serologic response and status of cellular immunity has been poorly studied.

Objective: This study was undertaken to assess humoral immune and cellular responses to the BNT162b2 messenger RNA (mRNA) COVID-19 vaccination in CLL.

Human Papillomavirus Oral Infection: Review of Methodological Aspects and Epidemiology.

Oral infection by Human Papillomavirus (HPV) has recently gained great attention because of its involvement in the development of a subset of head and neck squamous cell carcinoma. The role of specific Alpha-HPVs in this regard has been well established, whereas the contribution of other genera is under investigation. Despite their traditional classification as "cutaneous" types, Beta and Gamma HPVs are frequently detected in oral samples.

Do we really need fine-needle biopsy needle for an ultrasound-guided biopsy of pancreatic adenocarcinoma? A retrospective study.

Objective: Endoscopic ultrasound (EUS)-guided FNB was not demonstrated to be better than EUS fine-needle aspiration (FNA) to obtain adequate samples for diagnosis of pancreatic tumors. We report our experience using a 22-gauge needle aspiration to obtain both cytologic and histologic samples.

Patients And Methods: In a total of 232 patients (51% men), 22-gauge needles (Cook Medical) were used to obtain a cytological sample (between 2008 and 2016, Cohort A) and a cytologic and a histologic sample (between 2016 and 2019, Cohort B) to evaluate the usability of this needle to collect material for cytologic and histologic examination.

Concurrent and Concordant Anal and Oral Human PapillomaVirus Infections Are Not Associated with Sexual Behavior in At-Risk Males.

Men who have sex with men (MSM) harbor the highest prevalence of anal and oral Human Papillomavirus (HPV) infection, particularly if HIV-infected. We investigated anal and oral HPV infections in HIV-infected and HIV-uninfected MSM, to assess concurrent (HPV detected at both sites, irrespective of the genotypes), and concordant infections (same genotype[s] detected at both sites). Matched anal and oral samples from 161 MSM (85 HIV-infected, and 76 HIV-uninfected) were tested with the Linear Array.

Long-Term Persistence and Relevant Therapeutic Impact of High-Titer Viral-Neutralizing Antibody in a Convalescent COVID-19 Plasma Super-Donor: A Case Report.

A convalescent, non-severe, patient with COVID-19 was enrolled as a hyper-immune plasma voluntary donor by the Immuno-Hematology and Transfusion Unit of the Regina Elena National Cancer Institute in Rome, under the TSUNAMI national study criteria. During a nearly 6-month period (May-October 2020), the patient was closely monitored and underwent four hyperimmune plasma collections. Serum SARS-CoV-2 (anti-S + anti-N) IgG and IgM, anti-S1 IgA, and neutralizing titers (NTs) were measured.

The Wide Morphological Spectrum of Deep (Aggressive) Angiomyxoma of the Vulvo-Vaginal Region: A Clinicopathologic Study of 36 Cases, including Recurrent Tumors.

Background: Deep angiomyxoma (DAM) is currently included in the category of "specific stromal tumors of the lower female genital tract", along with angiomyofibroblastoma, cellular angiofibroma and myofibroblastoma. Given the high rate of local recurrences, it is crucial to recognize DAM from other tumors that possess indolent behaviour. In the present paper, we analyzed the morphological and immunohistochemical features of 42 surgically-resected vulvo-vaginal DAMs (36 primary and 6 recurrent lesions) in order to widen the morphological spectrum of this uncommon tumor.

Evaluation of HPV-Related Biomarkers in Anal Cytological Samples from HIV-Uninfected and HIV-Infected MSM.

Men who have sex with men (MSM) harbor the highest risk for anal carcinoma, mainly caused by Human Papillomavirus (HPV). The use of HPV-related biomarkers in the screening for this neoplasia is still debated. We assessed the association between high-risk (hr)HPV DNA, HPV16/18 DNA, hrHPV E6/E7 mRNA, and p16/Ki-67 with cytological abnormalities (any grade) and high-grade intraepithelial lesions (HSIL) in HIV-uninfected and HIV-infected MSM.

Early DMO: a predictor of poor outcomes following cataract surgery in diabetic patients. The DICAT-II study.

Background: The prospective DIabetes and CATaract Study II (DICAT II) was performed to characterise the risks of cataract surgery to the retinae of patients with early diabetic macular oedema (E-DMO).

Methods: DICAT II was a prospective, comparative, multicentre, observational study involving six Italian clinics. Patients were aged ≥55 years, had type 1 or 2 diabetes with spectral-domain optical coherence tomography evidence of ESASO classification Early DMO.

Safety of outpatient stem cell mobilization with low- or intermediate-dose cyclophosphamide in newly diagnosed multiple myeloma patients.

Objectives: Autologous stem cell transplantation is the gold standard for eligible newly diagnosed multiple myeloma patients. Patients are usually hospitalized for administration of mobilization chemotherapy. We aimed to assess safety and efficacy of mobilization therapy with low-dose (2 g/m ) and intermediate-dose (3-4 g/m ) cyclophosphamide administered as outpatient.

Objectives/hypothesis: The aim of this study was to assess the value of cell-free human papillomavirus-DNA (cfHPV-DNA) as a diagnostic test for the post-treatment surveillance of patients with HPV-positive head and neck squamous cell carcinoma (HNSCC) through a systematic review and meta-analysis.

Study Design: Systematic review and meta-analysis.

Methods: A literature search was conducted in three databases (MEDLINE, Embase, and Scopus) in January 2021.

Predictors of Oral Infection by Mucosal and Cutaneous Human Papillomaviruses in HIV-Infected and Uninfected Men Who Have Sex with Men of the OHMAR Study.

Mucosal Human Papillomaviruses (HPVs) play a role in the development of a subset of head and neck cancers. Cutaneous HPVs are abundantly present in the oral cavity. The determinants of these infections have not been extensively investigated.

Efficacy and tolerability of very low-volume bowel preparation in patients with inflammatory bowel diseases.

Objectives: An adequate bowel preparation is essential for a quality colonoscopy. Patients with inflammatory bowel disease (IBD) show low compliance with bowel preparation due to the large volume of lavage solution to be ingested, especially if active symptoms are present, and the frequency of having a colonoscopy. We evaluated the efficacy and tolerability of a very low-volume (VLV) polyethylene glycol (PEG)-based solution in patients with IBD.
