Homologous recombination deficiency in pancreatic neuroendocrine tumors.

Pancreatic Neuroendocrine tumors (pNETs) are a heterogeneous group of neoplasms whose tumor biology is still little known. Thanks to next-generation sequencing, pathogenic mutations in base-excision-repair gene and homologous recombination genes and seem to have a role in the development of pNETs. We assumed that Homologous Recombination Deficiency (HRD) could be a critical pathogenetic mechanism for pNETs.

Molecular portraits of patients with intrahepatic cholangiocarcinoma who diverge as rapid progressors or long survivors on chemotherapy.

Objective: Cytotoxic agents are the cornerstone of treatment for patients with advanced intrahepatic cholangiocarcinoma (iCCA), despite heterogeneous benefit. We hypothesised that the pretreatment molecular profiles of diagnostic biopsies can predict patient benefit from chemotherapy and define molecular bases of innate chemoresistance.

Design: We identified a cohort of advanced iCCA patients with comparable baseline characteristics who diverged as extreme outliers on chemotherapy (survival <6 m in rapid progressors, RP; survival >23 m in long survivors, LS).

Combination of transjugular intrahepatic portosystemic shunt and antegrade through-the-TIPS coil embolization for bleeding mixed-type ectopic ileal varices.

A 61-year-old man with alcoholic cirrhosis and a history of severe cholecystitis leading to secondary thrombosis of the recanalized paraumbilical vein was admitted to our hospital for recurrent gastrointestinal bleeding and severe anemia. Capsule endoscopy and CT angiography detected profuse bleeding in the proximal ileum from ectopic ileal varices. Hepatic venous-portal gradient (HVPG) measurement was consistent with severe portal hypertension.

Clinical-functional features of individuals with Osteogenesis Imperfecta and Ehlers-Danlos syndromes: A scoping review of assessment tools and ICF model.

Background: Clinical-functional assessment of patients affected by Osteogenesis Imperfecta and Ehlers-Danlos Syndromes is essential for clinical management. However, there is no clear information on disease-specific tools of assessment for clinical practice, thus limiting quantification and management of the diseases-related impairments.

Objective: The present scoping review was aimed at investigating the most common clinical-functional features and assessment tools in individuals with Osteogenesis Imperfecta and Ehlers-Danlos Syndromes, and to provide an updated International Classification of Functioning (ICF) model related to functional impairments for each disease.

Second-Line Chemotherapy in Elderly Patients with Advanced Biliary Tract Cancer: A Multicenter Real-World Study.

Objectives: The ABC-06 and the NIFTY trials recently established the role of second-line chemotherapy (2L) in patients with advanced biliary tract cancer (BTC). Our real-world study aimed to explore 2L in BTC patients aged ≥ 70 years old and to compare their outcomes with younger subjects. Methods: Institutional registries across three academic medical centers were retrospectively reviewed.

CtDNA-guided rechallenge with anti-EGFR therapy in RASwt metastatic colorectal cancer: Evidence from clinical practice.

Aim: To apply extended ctDNA-based RAS genotyping to clinical criteria for improving the selection of patients eligible for anti-EGFR-based rechallenge in a real-world setting.

Methods: ctDNA testing was prospectively applied to RASwt mCRC progressed after a first-line anti-EGFR-containing regimen and at least one other line. The primary endpoint was the objective response rate.

Ewing's Sarcoma of the Breast in a Young Woman: A Case Report and Review of the Literature.

Ewing's Sarcoma Family Tumors (ESFT) include classic Ewing's sarcoma of bone, extra-skeletal Ewing's sarcoma (EES), malignant small cell tumor of the chest wall (Askin tumor), and soft tissue-based Peripheral Primitive Neuroectodermal tumors (pPNET). The t(11;22)(q24;q12) translocation is associated with 85% of tumors and leads to EWS-FLI-1 (Ewing's Sarcoma-Friend Leukemia Integration-1) formation. This is a potent transforming gene that encodes a chimeric protein that plays a role in the genesis of Ewing's Sarcoma and Primitive Neuroectodermal Tumors.

Statins increase pathological response in locally advanced rectal cancer treated with chemoradiation: a multicenter experience.

To investigate the influence of various concomitant medications on outcomes in patients with locally advanced rectal cancer undergoing neoadjuvant chemoradiation. The authors retrospectively identified 246 patients from 2003 to 2018, collecting demographic and clinicopathological data of interest. Odds ratio (OR) was used to assess the association between concomitant drugs and outcomes.

Multicentre match-paired analysis of advanced biliary cancer long-term survivors: The BILONG study.

Background: Advanced biliary cancers (ABC) are aggressive malignancies with a median overall survival (mOS) <12 months when treated with first-line chemotherapy. Nevertheless, a subset of patients experiencing longer survival has been described in the updated analysis of ABC-02 trial. We aimed to provide a real-world description of ABC long-term survivors (LS), identifying which factors impact on survival.

Development and Multicentre Validation of the Modena Score to Predict Survival in Advanced Biliary Cancers Undergoing Second-Line Chemotherapy.

Background: The role of second-line chemotherapy in advanced biliary cancers (ABCs) has only recently been established in phase III randomized trial and the optimal selection of patients most likely to benefit from it remains challenging.

Methods: A cohort of 98 ABC treated second-line chemotherapy was used as a developmental dataset to identify covariates independently associated with overall survival (OS). Kaplan-Meier analysis was used to investigate the association between variables and OS and those retaining statistically significance were combined in a multiplexed score.

Carcinoid Crisis: A Misunderstood and Unrecognized Oncological Emergency.

Carcinoid Crisis represents a rare and extremely dangerous manifestation that can occur in patients with Neuroendocrine Tumors (NETs). It is characterized by a sudden onset of hemodynamic instability, sometimes associated with the classical symptoms of carcinoid syndrome, such as bronchospasm and flushing. Carcinoid Crisis seems to be caused by a massive release of vasoactive substances, typically produced by neuroendocrine cells, and can emerge after abdominal procedures, but also spontaneously in rare instances.

Third-line chemotherapy in advanced biliary cancers (ABC): pattern of care, treatment outcome and prognostic factors from a multicenter study.

Objectives: Here, we aim at describing the pattern of care, survival outcome and prognostic factors of ABC patients (pts) receiving third-line chemotherapy.

Methods: Institutional registries across three academic medical centers were retrospectively reviewed. Kaplan-Meier estimators were used to calculate survival, the log-rank test to make comparisons, and the Cox proportional hazard models to assess the progostic impact of variables.

First-Line Nivolumab Plus Low-Dose Ipilimumab for Microsatellite Instability-High/Mismatch Repair-Deficient Metastatic Colorectal Cancer: The Phase II CheckMate 142 Study.

Purpose: Nivolumab received US Food and Drug Administration approval as a single agent or in combination with ipilimumab in patients with microsatellite instability-high/mismatch repair-deficient (MSI-H/dMMR) metastatic colorectal cancer (mCRC) that progressed following treatment with a fluoropyrimidine, oxaliplatin, and irinotecan based on CheckMate 142. Presented are results of nivolumab plus low-dose ipilimumab in the first-line therapy cohort from the phase II CheckMate 142 study.

Patients And Methods: Patients with no prior treatment in the metastatic setting for MSI-H/dMMR CRC were treated with nivolumab every 2 weeks plus low-dose ipilimumab every 6 weeks until disease progression.

Irinotecan-based chemotherapy in extrapulmonary neuroendocrine carcinomas: survival and safety data from a multicentric Italian experience.

Purpose: Neuroendocrine carcinomas (NECs) are a rare subgroup of neuroendocrine neoplasms that occasionally originate from gastro-entero-pancreatic (GEP) tract. Evidence of the effectiveness of chemotherapy is scarce. Platinum plus Etoposide regimens are currently the standard treatment in first-line, while little data are available on second-line treatments.

The Prognostic Role of Early Skeletal Muscle Mass Depletion in Multimodality Management of Patients with Advanced Gastric Cancer Treated with First Line Chemotherapy: A Pilot Experience from Modena Cancer Center.

Background: Few data about the link between nutritional status and survival are available in the metastatic gastric cancer (GC) setting. The aim of this work was to evaluate the prognostic role of tissue modifications during treatment and the benefit of a scheduled nutritional assessment in this setting.

Methods: Clinical and laboratory variables of 40 metastatic GC patients treated at Modena Cancer Center were retrieved: 20 received a nutritional assessment on the oncology's discretion, the other 20 received a scheduled nutritional assessment at baseline and every 2-4 weeks.

Traumatic renal artery dissection: from imaging to management.

Injury to the renal artery following blunt trauma is detected increasingly due to widespread and early use of multidetector computed tomography (CT), but optimal treatment remains controversial as no guidelines are available. This review illustrates the spectrum of imaging findings of traumatic renal artery dissection based on our experience, with the aim of understanding the physiopathology of ischaemic damage to the kidney, and the process of choosing the best therapeutic strategy (conservative, endovascular, surgical). Five main patterns of traumatic renal artery dissection are described: avulsion of renal hilum; dissection of the segmental renal branches; preocclusive main renal artery dissection; renal artery stenosis without flow limitation; thrombogenic renal artery intimal tear.

PD-1 blockade in deficient mismatch repair mixed adenoneuroendocrine carcinoma of the stomach: new hope for an orphan disease.

Introduction: Mixed adenoneuroendocrine carcinoma (MANEC) is an uncommon and aggressive tumor arising throughout the entire gastrointestinal tract. Treatment options are limited, and survival is dismal with conventional therapies.

Case Description: We present the case of a 66-year-old man who was diagnosed with a locally advanced MANEC of the gastroesophageal junction.

Cancer treatment during the coronavirus disease 2019 pandemic: Do not postpone, do it!

At the end of January 2020, a novel betacoronavirus, known as severe acute respiratory syndrome coronavirus 2, progressively spread in Italy. Patients with cancer are considered more prone to infections because of the immunosuppressive status due to both malignancy and anticancer treatments. From the first Italian government restrictions (23rd February), Modena Cancer Center adopted practical health vigilance recommendations to minimise the risk of exposure to the virus without overlooking cancer management.

mTOR Pathway Expression as Potential Predictive Biomarker in Patients with Advanced Neuroendocrine Tumors Treated with Everolimus.

Background: Everolimus (Eve), which is a mammalian target of Rapamicin (mTOR) inhibitor, is part of the therapeutic armamentarium of neuroendocrine tumors (NETs). Currently, there are no validated biomarkers predicting Eve efficacy in NETs. In this study, we explore whether the expression of phosphorilated (p)-mTOR and p70S6-kinase (S6K), a downstream effector of mTOR, correlates with the outcome of patients with NET that were treated with Eve.

Non-Operative Management Versus Total Mesorectal Excision for Locally Advanced Rectal Cancer with Clinical Complete Response After Neoadjuvant Chemoradiotherapy: a GRADE Approach by the Rectal Cancer Guidelines Writing Group of the Italian Association of Medical Oncology (AIOM).

Background: The standard approach for locally advanced rectal cancer (LARC) is neoadjuvant chemoradiotherapy (nCRT) followed by total mesorectal excision (TME). After nCRT 20% of patients achieve a clinical complete response (pCR) and could be treated with a non-operative management (NOM).

Methods: The panel of the Italian Association of Medical Oncology (AIOM) Guidelines on rectal cancer applied the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach addressing the following question: Should NOM vs.

Activity and safety of temozolomide in advanced adrenocortical carcinoma patients.

Objective: Temozolomide has shown a significant anti-proliferative activity on adrenocortical cancer (ACC) cells in vitro.

Design: On the basis of these results the drug was prescribed as second/third line in advanced metastatic ACC patients in four referral centers in Italy.

Methods: We retrospectively collected anagraphic, clinical and pathological data of patients with advanced ACC with disease progression to standard chemotherapy plus mitotane who were treated with temozolomide at the dose of 200 mg/m2/die given for 5 consecutive days every 28 days.

A Dose-finding and Biomarker Evaluation Phase Ib Study of Everolimus in Association With 5-Fluorouracil and Pelvic Radiotherapy as Neoadjuvant Treatment of Locally Advanced Rectal Cancer (E-LARC Study).

Background: During the past 20 years, considerable improvement has occurred in the treatment of patients with locally advanced rectal cancer (LARC). With the introduction of multimodal treatment, refinements in preclinical staging and improvements in surgical skills, local relapse is no longer the major problem for patients with LARC. However, many patients die of metastatic disease.
