Neuroendocrine neoplasms of the breast: a multicenter retrospective Italian study.

Background: The aim of our retrospective study was to describe the immunophenotypic characteristics of neuroendocrine breast neoplasm (BNEN), a peculiar and rare type of breast carcinoma.

Methods: Pathological data from 51 patients affected by BNEN were retrospectively evaluated, and 44 patients were considered eligible (7 patients with incomplete data were excluded). The patients were followed in six different Italian hospitals between 2009 and 2019.

Durvalumab plus gemcitabine and cisplatin in advanced biliary tract cancer: A large real-life worldwide population.

Background: The TOPAZ-1 phase III trial showed a survival benefit with durvalumab plus gemcitabine and cisplatin in patients with advanced biliary tract cancer (BTC). To understand this combination's real-world efficacy and tolerability, we conducted a global multicenter retrospective analysis of its first-line treatment outcomes.

Methods: We included patients with unresectable, locally advanced, or metastatic BTC treated with durvalumab, gemcitabine, and cisplatin at 39 sites in 11 countries (Europe, the United States, and Asia).

Sarcopenia in Breast Cancer Patients: A Systematic Review and Meta-Analysis.

We estimated the prevalence and clinical outcomes of sarcopenia among breast cancer patients. A systematic literature search was carried out for the period between July 2023 and October 2023. Studies with breast cancer patients evaluated for sarcopenia in relation to overall survival (OS), progression-free survival (PFS), relapse of disease (DFS), pathological complete response (pCR), or toxicity to chemotherapy were included.

Predictive Factors of Response to Streptozotocin in Neuroendocrine Pancreatic Neoplasms.

Pancreatic neuroendocrine neoplasms (Pan-NENs) may exhibit a heterogeneous clinical course, ranging from indolent to progressive/metastatic behavior. In the latter scenario, streptozocin (STZ) is considered the cornerstone of systemic treatment; however, response to STZ-based chemotherapy may vary among individuals. In this narrative review, we aimed to identify the predictive factors of response to STZ in advanced Pan-NENs.

Surgical and survival outcomes with perioperative or neoadjuvant immune-checkpoint inhibitors combined with platinum-based chemotherapy in resectable NSCLC: A systematic review and meta-analysis of randomised clinical trials.

The use of neoadjuvant or perioperative anti-PD(L)1 was recently tested in multiple clinical trials. We performed a systematic review and meta-analysis of randomised trials comparing neoadjuvant or perioperative chemoimmunotherapy to neoadjuvant chemotherapy in resectable NSCLC. Nine reports from 6 studies were included.

Thyroid transcription factor-1 expression in lung neuroendocrine tumours: a gender-related biomarker?

Purpose: Thyroid transcription factor-1 (TTF-1) assessed by immunohistochemistry (IHC) is a specific biomarker for lung adenocarcinoma, and is commonly used to confirm the pulmonary origin of neuroendocrine tumours (NET). The majority of the available data suggest that TTF-1 is favourable prognostic biomarker for lung adenocarcinomas, whereas its role is more conflicting for lung NET. The main aim of this multicenter retrospective study was to investigate the potentially relevant associations between TTF-1 biomarker and clinical and pathological features of the study population, as well as determine TTF-1 prognostic effect on the clinical outcome of the patients.

Platelet-derived circRNAs signature in patients with gastroenteropancreatic neuroendocrine tumors.

Background: Neuroendocrine tumors (NETs) early diagnosis is a clinical challenge that require a deep understanding of molecular and genetic features of this heterogeneous group of neoplasms. However, few biomarkers exist to aid diagnosis and to predict prognosis and treatment response. In the oncological field, tumor-educated platelets (TEPs) have been implicated as central players in the systemic and local responses to tumor growth, thereby altering tumor specific RNA profile.

Capecitabine and Temozolomide (CAPTEM) in Advanced Neuroendocrine Neoplasms (NENs): A Systematic Review and Pooled Analysis.

Background: Retrospective studies and single center experiences suggest a role of capecitabine combined with temozolomide (CAPTEM) in neuroendocrine tumors (NENs).

Methods: We performed a systematic review to assess the efficacy and safety of CAPTEM in patients affected with NENs, with the aim to better clarify the role of this regimen in the therapeutic algorithm of NENs.

Results: A total of 42 articles and 1818 patients were included in our review.

Immunotherapy for Aggressive and Metastatic Pituitary Neuroendocrine Tumors (PitNETs): State-of-the Art.

Background: Aggressive and metastatic PitNETs are challenging conditions. Immune checkpoint inhibitors (ICIs) are currently considered in cases resistant to temozolomide (TMZ). However, clinical experience is essentially limited to case reports, with variable outcomes.

Prognostic significance of laterality in lung neuroendocrine tumors.

Purpose: Well-differentiated lung neuroendocrine tumors (Lu-NET) are classified as typical (TC) and atypical (AC) carcinoids, based on mitotic counts and necrosis. However, prognostic factors, other than tumor node metastasis (TNM) stage and the histopathological diagnosis, are still lacking. The current study is aimed to identify potential prognostic factors to better stratify lung NET, thus, improving patients' treatment strategy and follow-up.

Angiogenic factors as prognostic markers in neuroendocrine neoplasms.

Purpose: Angiogenic markers in neuroendocrine neoplasms (NENs) have recently received increasing attention, but their clinical role remains unclear. The aim of this study was to evaluate the role of angiogenic markers in NEN aggressiveness and prognosis.

Methods: We performed a prospective observational study including 46 consecutive patients with proven NENs of pulmonary (45.

Emerging Role of PARP Inhibitors in Metastatic Triple Negative Breast Cancer. Current Scenario and Future Perspectives.

Triple negative tumors represent 15% of breast cancer and are characterized by the lack of estrogen receptors, progesterone receptor, and HER2 amplification or overexpression. Approximately 25% of patients diagnosed with triple negative breast cancer carry a germline BRCA1 or BRCA2 mutation. They have an aggressive biology, and chemotherapy has been the mainstay of treatment for a long time.

NETest: A Systematic Review Focusing on the Prognostic and Predictive Role.

The NETest is a standardized and reproducible liquid biopsy for neuroendocrine tumors (NETs). It evaluates the expression of 51 NET genes by real-time polymerase chain reaction, providing an accurate molecular profile of the neoplasm. Diagnostic utility of NETest has been widely demonstrated, while its role in predicting prognosis and treatment response is less studied.

Neuroendocrine Carcinomas with Atypical Proliferation Index and Clinical Behavior: A Systematic Review.

Background: Highly proliferative (G3) neuroendocrine neoplasms are divided into well differentiated tumors (NETs) and poorly differentiated carcinomas (NECs), based on the morphological appearance. This systematic review aims to evaluate the clinicopathological features and the treatment response of the NEC subgroup with a Ki67 labeling index (LI) < 55%.

Methods: A literature search was performed using MEDLINE, Cochrane Library, and Scopus between December 2019 and April 2020, last update in October 2020.

Capecitabine in treating patients with advanced, persistent, or recurrent cervical cancer: an active and safe option?

: Advanced, persistent or recurrent cervical cancer in patients not amenable to curative surgery or radiotherapy predicts a dismal prognosis. Systemic chemotherapy based on paclitaxel/cisplatin ± bevacizumab is the current standard of care. However, once progression occurs, the possibility of alternative treatment options is very limited.

A Systemwide Approach for Navigating the Dilemma of Oral Factor Xa Inhibitor Interference With Unfractionated Heparin Anti-Factor Xa Concentrations.

Background: Oral factor Xa inhibitors are known to significantly increase heparin anti-Xa concentrations, which leads to inaccuracies when monitoring intravenous unfractionated heparin (IV UFH). Guidance for managing this laboratory interference is lacking, creating substantial uncertainty in clinical practice.

Objective: To describe a strategy used by a large academic institution for managing the controversy of laboratory interference in the setting of oral factor Xa inhibitor use and provide effectiveness and safety data for this approach.

Natural History and Management of Familial Paraganglioma Syndrome Type 1: Long-Term Data from a Large Family.

Head and neck paragangliomas are the most common clinical features of familial paraganglioma syndrome type 1 caused by succinate dehydrogenase complex subunit D (SDHD) mutation. The clinical management of this syndrome is still unclear. In this study we propose a diagnostic algorithm for SDHD mutation carriers based on our family case series and literature review.

Expression of ER, PgR, HER-2, and Ki-67 in core biopsies and in definitive histological specimens in patients with locally advanced breast cancer treated with neoadjuvant chemotherapy.

Purpose: Many studies have indicated that the response to therapy and the prognostic impact of a pathologic complete response after neoadjuvant treatment differ among breast cancer subtypes.

Methods: The aim of our study is to evaluate the effect of this treatment on the expression of estrogen and progesterone receptors, human epidermal growth hormone receptor 2 and Ki67 in breast cancer. We identified 125 patients.

Metachronous and Synchronous Cancers in Patients with Neuroendocrine Tumors.
