Recurrent gastric amphicrine tumor with neuroendocrine and pancreatic acinar cell differentiation and somatic MEN1 inactivation arisen during immunotherapy.

Amphicrine neoplasms (ANs) are poorly understood epithelial malignancies composed of cells with co-existing exocrine-neuroendocrine features. Here, we report a recurrent mucin-producing gastric amphicrine tumor co-expressing neuroendocrine (chromogranin-A, synaptophysin, and CD56) and pancreatic acinar cell (BCL10 and trypsin) markers, arisen in a 64-year-old woman during adjuvant immunotherapy for melanoma. Ki-67 was < 2%.

Real world data of cemiplimab in locally advanced and metastatic cutaneous squamous cell carcinoma.

Background: Cutaneous squamous cell carcinoma (cSCC) has an overall favourable outcome, except for patients with an advanced stage disease. The programmed death protein-1 (PD-1) inhibitor cemiplimab has been approved for use in advanced cSCC. We report clinical outcomes from the named patient programme-compassionate use of cemiplimab for patients with advanced cSCC in Italy.

Influence of different lipid emulsions on specific immune cell functions in head and neck cancer patients receiving supplemental parenteral nutrition: An exploratory analysis.

Objectives: The effect of diet on immune responses is an area of intense investigation. Dietary lipids have been shown to differently influence and fine-tune the reactivity of immune cell subsets, thus potentially affecting clinical outcomes. Patients with head and neck squamous cell carcinoma face malnutrition, due to swallowing impairment related to the tumor site or to treatment sequalae, and may need supplemental parenteral nutrition (SPN) in addition to oral feeding when enteral nutrition is not feasible.

Organisational challenges, volumes of oncological activity and patients' perception during the severe acute respiratory syndrome coronavirus 2 epidemic.

Background: On February 23rd, the 1st case of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was diagnosed at the University Hospital Trust of Verona, Italy. On March 13th, the Oncology Section was converted into a 22-inpatient bed coronavirus disease (COVID) Unit, and we reshaped our organisation to face the SARS-CoV-2 epidemic, while maintaining oncological activities.

Methods: We tracked down (i) volumes of oncological activities (January 1st - March 31st, 2020 versus the same period of 2019), (ii) patients' and caregivers' perception and (iii) SARS-CoV-2 infection rate in oncology health professionals and SARS-CoV-2 infection-related hospital admissions of "active"' oncological patients.

Linac-based stereotactic body radiation therapy for unresectable locally advanced pancreatic cancer: risk-adapted dose prescription and image-guided delivery.

Background: Stereotactic body radiation therapy (SBRT) represents a new treatment option for locally advanced pancreatic cancer (LAPC). An accurate treatment planning with risk-adapted dose prescription with adherence to specific dose constraints for organs at risk (OARs) and the use of daily cone beam CT (CBCT) for image guidance could allow an effective and safe treatment delivery. Here, feasibility and efficacy of SBRT in LAPC treated in our cancer care center are reported.

Cholangiocarcinoma.

Biliary tract cancer accounts for <1% of all cancers and affects chiefly an elderly population, with predominance in men. We distinguish cholangiocarcinoma (intrahepatic, hilar and distal) and gallbladder cancer, with different pathogenesis and prognosis. The treatment is based on surgery (whenever possible), radiotherapy in selected cases, and chemotherapy.

Efficacy of trastuzumab in unselected patients with HER2-positive metastatic breast cancer: a retrospective analysis.

Aims And Background: The addition of trastuzumab to chemotherapy for HER2-positive metastatic breast cancer has significantly improved progression-free survival and overall survival, although most patients develop resistance or have a primarily resistant disease. The aim of the study was to describe the efficacy and safety of a first-line treatment in unselected metastatic HER2-positive breast cancer patients, treated according to clinical practice.

Methods: From 2000 to 2009, we conducted a retrospective multi-institutional analysis of 182 consecutive patients with HER2-positive metastatic breast cancer who underwent first-line treatment with trastuzumab.

ALK/EML4 fusion gene may be found in pure squamous carcinoma of the lung.

Introduction: The report of cases of lung squamous cell cancers harboring anaplastic lymphoma kinase (ALK) gene rearrangements raises the question whether this histologic subtype should be also evaluated for such molecular predictive test.

Methods: A consecutive series of 40 lung pure squamous cell carcinomas were analyzed for ALK gene status by fluorescence in situ hybridization. Squamous differentiation was validated using an immunohistochemical panel including n-p63 (p40), cytokeratin (CK) 5/6, sex-determining region Y (SRY)-Box2 (SOX2), thyroid transcription factor 1, CK7, and Napsin-A.

Male breast cancer: clinical features and multimodal treatment in a retrospective survey analysis at Italian centers.

Aims And Background: We report a collection of data about early breast cancer in male patients from 13 Italian institutions.

Methods And Study Design: We obtained data from patient charts and performed statistical analysis. The primary end points were overall survival and disease-free survival.

Single agent panitumumab in KRAS wild-type metastatic colorectal cancer patients following cetuximab-based regimens: Clinical outcome and biomarkers of efficacy.

Background: Few data are available outlining outcomes of panitumumab in advanced colorectal cancer patients benefiting from prior cetuximab-based regimens.

Patients And Methods: Thirty patients with KRAS wild type metastatic colorectal cancer with clinical benefit from prior cetuximab-based regimens between May 2004 and October 2011 were reviewed at nine Italian Institutions. Inclusion key criteria included interruption of cetuximab for reasons other than progressive disease.

True 3q chromosomal amplification in squamous cell lung carcinoma by FISH and aCGH molecular analysis: impact on targeted drugs.

Squamous lung carcinoma lacks specific "ad hoc" therapies. Amplification of chromosome 3q is the most common genomic aberration and this region harbours genes having role as novel targets for therapeutics. There is no standard definition on how to score and report 3q amplification.

Italian Survey on adjuvant treatment of non-small cell lung cancer (ISA).

Background: A recent pooled analysis of randomized trials indicated significant improvement in overall survival from cisplatin-based adjuvant chemotherapy for non-small cell lung cancer (NSCLC), depending on disease stage (only in stages II and III) and PS (≤ 1). Post-operative radiotherapy (RT) is optional for pN2 tumours.

Patients And Methods: To evaluate opinions and daily clinical practice of Italian Oncologists about adjuvant treatment of NSCLC, a 46-item questionnaire was delivered via e-mail.

Colorectal cancer treatment in elderly patients: an update on recent clinical studies.

Colorectal cancer (CRC) is one of the most common cancers in the Western world, with > 500,000 new cases diagnosed each year. One of the strongest risk factors for colon cancer is age. Physicians and their older patients commonly face the dilemma of whether to give/receive systemic chemotherapy for CRC.

Utility of 18F-FDG PET and contrast-enhanced CT scan in the assessment of residual liver metastasis from colorectal cancer following adjuvant chemotherapy.

Background: Neoadjuvant chemotherapy has been successfully used in the treatment of patients with colorectal liver metastases. The selection of patients for surgical resection after chemotherapy still poses a significant clinical challenge. (18)F-FDG PET is a useful tool in the assessment of liver metastases but the data regarding its sensitivity after chemotherapy is scarce.

Oral ulcer as an exclusive sign of gastric cancer: report of a rare case.

Background: The oral cavity is a rare but occasional target for metastases, which may masquerade as various benign and inflammatory lesions, and sometimes also be asymptomatic. Oral metastatic lesions have been described in various cancers, particularly lung, breast and kidney carcinoma.

Case Presentation: We here describe an uncommon case of a hard palate mucosa and gingival metastasis from gastric carcinoma that was originally diagnosed as a periodontal disease.
