Impact of Regional Metastasis on Survival for Patients with Nonfunctional Pancreatic Neuroendocrine Tumors: A Systematic Review.

Background: Controversy exists regarding the benefit of lymphadenectomy for nonfunctional pancreatic neuroendocrine tumors (NF-PNET).

Patients And Methods: MEDLINE/PubMed, EMBASE, and the Cochrane Library were searched for studies of pancreatic neuroendocrine tumors (PNET) published between 1990 and 2021. Studies of functional PNET were excluded.

Treatment Patterns of Long-Acting Somatostatin Analogs for Neuroendocrine Tumors.

Long-acting somatostatin analog therapy (LA-SSA) is recommended as first-line therapy for treatment of unresectable or metastatic neuroendocrine tumors (NETs). Understanding treatment sequencing and dosing patterns of LA-SSA is essential for clinical decision-making to provide value-based management of NETs. To describe treatment patterns of LA-SSA among patients with NETs and subgroups with carcinoid syndrome (CS) in the United States.

A qualitative study to understand the experience of somatostatin analog treatments from the perspective of patients with neuroendocrine tumors.

Purpose: Neuroendocrine tumors (NETs) negatively impact patients' quality of life. Octreotide long-acting release (LAR) and lanreotide depot are somatostatin analogs (SSAs) approved to treat NETs. The study objective was to explore SSA treatment experiences and preferences of patients with NETs.

Neuroendocrine Tumors: a Relevant Clinical Update.

Purpose Of Review: The field of neuroendocrine oncology has changed much since the time of Oberndorfer first described and coined the term carcinoid. The purpose of this review is to summarize recent findings and highlight clinically relevant updates in the management of NENs, particularly those that are practice changing.

Recent Findings: Neuroendocrine tumors (NETs) have replaced carcinoid tumor, for the most part.

Lanreotide autogel/depot in advanced enteropancreatic neuroendocrine tumours: final results of the CLARINET open-label extension study.

Purpose: In the phase III CLARINET study (NCT00353496), lanreotide autogel/depot (lanreotide) significantly improved progression-free survival (PFS) vs placebo in patients with non-functioning intestinal or pancreatic neuroendocrine tumours (NETs). The aim of CLARINET open-label extension (OLE) (NCT00842348) was to evaluate long-term safety and efficacy of lanreotide in these patients.

Methods: Patients from the CLARINET study were eligible for the OLE if they had stable disease (irrespective of treatment group) or progressive disease (PD) (placebo-treated patients only).

Prognostic value of the neutrophil/lymphocyte ratio in enteropancreatic neuroendocrine tumors.

Accessible prognostic tools are needed to individualize treatment of neuroendocrine tumors (NETs). Data suggest neutrophil/lymphocyte ratios (NLRs) have prognostic value in some solid tumors, including NETs. In the randomized double-blind CLARINET study (NCT00353496; EudraCT 2005-004904-35), the somatostatin analog lanreotide autogel/depot increased progression-free survival (PFS) compared with placebo in patients with inoperable or metastatic intestinal and pancreatic NETs (grades 1-2, Ki-67 < 10%).

Molecular pathways and targeted therapy in cholangiocarcinoma.

Cholangiocarcinoma (CCA) encompasses a rare group of malignancies arising from epithelial cells lining the biliary tree that connects the liver and gallbladder to the small intestine. Most patients present with advanced incurable disease that has a poor prognosis, and standard treatment options remain limited. Effective nontoxic treatment options for advanced CCA are needed.

Immunotherapy and targeted therapy-the new roadmap in cancer treatment.

Immunotherapy is the new frontier in cancer medicine. This manuscript summarizes historical aspect of immunotherapy, particularly its pathway to drug approval as the main therapeutic modality used in clinical medicine. We will discuss the role of immunotherapy in treating various types of cancers and how the treatment landscape once dominated by chemotherapy is rapidly changing.

Stereotactic body radiation therapy and immunotherapy.

Immunotherapy has revolutionized the treatment of various types of cancers in recent years. Since the US Food and Drug Administration approval of the anti-cytotoxic T-lymphocyte-associated antigen 4 agent ipilimumab for late-stage melanoma in 2011, results from multiple clinical trials have proven the benefit of immunotherapy in the treatment of other cancers. However, therapeutic resistance to immunotherapy often develops.

Epidemiological risk factors for adrenocortical carcinoma: A hospital-based case-control study.

Adrenocortical carcinoma (ACC) is a rare malignancy whose risk factors are unclear. We explored the association of ACC risk with exposure to selected environmental factors, with a focus on cigarette smoking. We conducted a hospital-based case-control study at The University of Texas MD Anderson Cancer Center.

Patterns of Care Among Real-World Patients with Metastatic Neuroendocrine Tumors.

Background: Although recent pivotal trials (PROMID, CLARINET) have established somatostatin analogs (SSAs) as first-line agents for neuroendocrine tumors (NETs), their use in clinical practice is largely unknown. We aimed to understand real-world management and treatment of gastroenteropancreatic (GEP) NETs.

Materials And Methods: Patients with metastatic GEP-NETs treated with SSAs, lanreotide depot or octreotide long-acting release (LAR), between January 1, 2015, and December 31, 2015, were identified from a U.

Effect of Lanreotide Depot/Autogel on Urinary 5-Hydroxyindoleacetic Acid and Plasma Chromogranin A Biomarkers in Nonfunctional Metastatic Enteropancreatic Neuroendocrine Tumors.

Background: Urinary 5-hydroxyindoleacetic acid (5-HIAA) is an established biomarker in neuroendocrine tumors and carcinoid syndrome; however, its role in nonfunctional neuroendocrine tumors is not defined. We present post hoc data on urinary 5-HIAA and plasma chromogranin A (CgA) from the CLARINET study.

Methods: Patients with well- or moderately differentiated, nonfunctioning, locally advanced or metastatic enteropancreatic neuroendocrine tumors were randomized to deep subcutaneous lanreotide depot/autogel 120 mg or placebo once every 28 days for 96 weeks.

BIOCHEMICAL RESPONSES IN SYMPTOMATIC AND ASYMPTOMATIC PATIENTS WITH NEUROENDOCRINE TUMORS: POOLED ANALYSIS OF 2 PHASE 3 TRIALS.

Objective: Neuroendocrine tumors (NETs) are associated with elevated 5-hydroxyindoleacetic acid (5-HIAA) and chromogranin A (CgA) levels. This study aimed to analyze relationships between urinary 5-HIAA and plasma CgA levels and clinical outcomes.

Methods: Centrally assessed biomarker levels and correlations with progression-free survival (PFS) and carcinoid syndrome (CS) symptom control were evaluated in a pooled analysis of CLARINET (96-week randomized, double-blind, placebo-controlled) and ELECT (16-week randomized, double-blind, placebo-controlled, 32-week initial open label and ≥2 year long-term extension open label) studies of adults with NETs, with (ELECT) or without (CLARINET) CS at 97 institutions.

Two birds, one stone: hesperetin alleviates chemotherapy-induced diarrhea and potentiates tumor inhibition.

Chemotherapy-induced diarrhea (CID), with clinical high incidence, adversely affects the efficacy of cancer treatment and patients' quality of life. Our study demonstrates that the citrus flavonoid hesperetin (Hst) has a superior potential as a new agent to prevent and alleviate CID. In the animal model for irinotecan (CPT-11) induced CID, Hst could selectively inhibit intestinal carboxylesterase (CES2) and thus reduce the local conversion of CPT-11 to cytotoxic SN-38 which causes intestinal toxicity.

Budget impact of somatostatin analogs as treatment for metastatic gastroenteropancreatic neuroendocrine tumors in US hospitals.

Objective: With the introduction of new therapies, hospitals have to plan spending limited resources in a cost-effective manner. To assist in identifying the optimal treatment for patients with locally advanced or metastatic gastroenteropancreatic neuroendocrine tumors, budget impact modeling was used to estimate the financial implications of adoption and diffusion of somatostatin analogs (SSAs).

Patients And Methods: A hypothetical cohort of 500 gastroenteropancreatic neuroendocrine tumor patients was assessed in an economic model, with the proportion with metastatic disease treated with an SSA estimated using published data.

Recent advances in the management of gastroenteropancreatic neuroendocrine tumors: insights from the 2017 ASCO Gastrointestinal Cancers Symposium.

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare malignancies that originate in the gastrointestinal system. GEP-NETs are typically indolent, but tumors known as "functional" secrete hormones that can lead to a complex of symptoms, including flushing, diarrhea, bronchospasm, and valvular heart disease. Management of patients with GEP-NETs requires a multidisciplinary approach, as treatment modalities include surgery, radiology, and pharmacotherapy.

Estrogen Replacement Reduces Risk and Increases Survival Times of Women With Hepatocellular Carcinoma.

Background & Aims: Environmental factors have been identified that affect risk of hepatocellular carcinoma (HCC), but little is known about the effects of sex hormones on liver cancer development or outcome. The authors investigated whether menopause hormone therapy (MHT) affects risk, age at onset, or outcome of HCC.

Methods: We performed a case-control study of 234 female patients treated for HCC at a tertiary medical center and with 282 healthy women (controls) from January 1, 2004 through May 31, 2015.

Leukapheresis reduces 4-week mortality in acute myeloid leukemia patients with hyperleukocytosis - a retrospective study from a tertiary center.

Hyperleukocytosis in patients with acute myeloid leukemia (AML) can lead to leukostasis, which if left untreated, has a high mortality. While prompt cytoreductive chemotherapy is essential, treatment with leukapheresis is controversial. This study investigated the outcomes of patients with hyperleukocytosis who received leukapheresis.

Neuroendocrine Tumors and Lanreotide Depot: Clinical Considerations and Nurse and Patient Preferences.

Background: Somatostatin analogs (SSAs) are a mainstay therapy for the treatment of carcinoid syndrome associated with neuroendocrine tumors (NETs). They are effective for a range of gastroenteropancreatic NETs (GEP-NETs). Lanreotide depot (Somatuline®) is an SSA that is approved for the treatment of GEP-NETs to improve progression-free survival (PFS).

The pivotal role of mammalian target of rapamycin inhibition in the treatment of patients with neuroendocrine tumors.

Significant advances have been made toward understanding the biology of neuroendocrine tumors (NET) in terms of defining prognosis and improving clinical management; however, many unmet needs remain. The treatment landscape for NET has evolved, with the approval of the targeted agents everolimus and sunitinib for the treatment of advanced pancreatic NET in 2011 followed by the approval of everolimus for the treatment of advanced nonfunctional gastrointestinal and lung NET in 2016. Mammalian target of rapamycin (mTOR) and components of the mTOR pathway play pivotal roles in NET pathogenesis.

Lanreotide Depot: An Antineoplastic Treatment of Carcinoid or Neuroendocrine Tumors.

Purpose: Peptide drugs for antineoplastic therapies usually have low oral bioavailability and short in vivo half-lives, requiring less preferred delivery methods. Lanreotide depot is a sustained-release somatostatin analog (SSA) formulation produced via an innovative peptide self-assembly method. Lanreotide is approved in the USA and Europe to improve progression-free survival (PFS) in patients with unresectable gastroenteropancreatic neuroendocrine tumors (GEP-NETs) and also approved in Europe for symptom control in carcinoid syndrome associated with GEP-NETs.

A Phase I/II Study of Docetaxel, Oxaliplatin, and Fluorouracil (D-FOX) Chemotherapy in Patients With Untreated Locally Unresectable or Metastatic Adenocarcinoma of the Stomach and Gastroesophageal Junction.

Background: A randomized phase III study established docetaxel, cisplatin, and 5-fluorouracil (DCF) as one of the standard treatments for patients with untreated advanced gastric cancer (AGC). However, DCF use is limited due toxicity. With the purpose to evaluate a less toxic regimen, we conducted a single arm, phase I/II trial of modified DCF (oxaliplatin, 5-fluorouracil, and docetaxel [D-FOX]) for untreated AGC patients.
