- Pulmonary carcinoids (PCs) display the common features of all well-differentiated neuroendocrine neoplasms (NEN) and are classified as low- and intermediate-grade malignant tumours (i.e., typical and atypical carcinoid, respectively). There is a paucity of randomised studies dedicated to advanced PCs and management principles are drawn from the larger gastroenteropancreatic NEN experience. There is growing evidence that NEN anatomic subgroups have different biology and different responses to treatment and, therefore, should be investigated as separate entities in clinical trials. In this review, we discuss the existing evidence and limitations of tumour classification, diagnostics and staging, prognostication, and treatment in the setting of PC, with focus on unmet medical needs and directions for the future.

- Systemic chemotherapy is indicated in progressive or bulky advanced pancreatic neuroendocrine tumors (NETs) and in grade 3 (G3) neuroendocrine neoplasms (NENs) as per ENETS guidelines. Chemotherapy may be considered in NETs of other sites (lung, thymus, stomach, colon, and rectum) under certain conditions (e.g., when Ki-67 is at a high level [upper G2 range], in rapidly progressive disease and/or after failure of other therapies, or if somatostatin receptor imaging is negative). An ENETS Consensus Conference was held in Antibes (2015) to elaborate guidelines on the standards of care of different diagnostic procedures and therapeutic interventions in NENs. This article provides guidance on chemotherapy including therapeutic indications, dosing schedules, adverse events (including prevention and management), drug interactions, and evaluation of treatment effect for the chemotherapy agents most commonly used in NENs (streptozocin, dacarbazine, fluoropyrimidines, platinum compounds, etoposide, and irinotecan).

- Introduction: Telotristat ethyl is indicated for use in combination with somatostatin analogs (SSAs) to treat carcinoid syndrome (CS) diarrhea uncontrolled by SSAs alone in adults, but long-term safety and efficacy data beyond 48 weeks are needed.Objectives: The aims of the study were to evaluate the long-term safety and tolerability of telotristat ethyl and its effect on quality of life (QOL) in patients with CS.Methods: In this phase 3, nonrandomized, multicenter, open-label, long-term extension study (TELEPATH), patients who participated in phase 2 or 3 trials of telotristat ethyl continued treatment at their present dose level (250 or 500 mg thrice daily) for 84 weeks. Safety and tolerability, the primary endpoint, were assessed by monitoring adverse events (AEs), serious AEs, AEs of special interest (AESIs; including liver-related AEs, depression, and gastrointestinal AEs), and deaths. The secondary objective was to evaluate changes in patients’ QOL using validated cancer questionnaires and a subjective global assessment of CS symptoms.Results: In 124 patients exposed to telotristat ethyl for a mean of 102.6 ± 53.2 weeks, the type and frequency of AEs were consistent with those reported in previous trials. The occurrence of AESIs was not related to dosage or duration of therapy. Most AEs were mild to moderate in severity, and no deaths were related to telotristat ethyl. QOL scores remained stable, and the majority of patients reported adequate symptom relief throughout the study.Conclusions: Safety results of TELEPATH support the long-term use of telotristat ethyl in patients with CS diarrhea. Telotristat ethyl was well-tolerated and associated with sustained improvement in QOL scores (NCT02026063).

ENETS Consensus Guidelines for the Standards of Care in Neuroendocrine Tumors : Pre- and Perioperative Therapy in Patients with Neuroendocrine Tumors

- Neuroendocrine tumors of the small intestine are the most common causes of the carcinoid syndrome. Carcinoid heart disease occurs in more than half of the patients with the carcinoid syndrome. Patients with carcinoid heart disease who need to undergo surgery should also undergo preoperative evaluation by an expert cardiologist. Treatment with longacting somatostatin analogs aims at controlling the excessive hormonal output and symptoms related to the carcinoid syndrome and at preventing a carcinoid crisis during interventions. Patients with a gastrinoma require pre- and postoperative treatment with high doses of proton pump inhibitors. Patients with a glucagonoma require somatostatin analog treatment and nutritional supplementation. Patients with a VIPoma also require somatostatin analog treatment and intravenous fluid and electrolyte therapy. Insulinoma patients generally require intravenous glucose infusion prior to operation. In patients with localized operable insulinoma, somatostatin analog infusion should only be considered after the effect of this therapy has been electively studied.

ENETS Consensus Guidelines for the Standards of Care in Neuroendocrine Neoplasms : Systemic Therapy - Biotherapy and Novel Targeted Agents

- Systemic therapies established in the management of patients with neuroendocrine tumors (NETs) include somatostatin analogs and interferon-alpha, also referred to as biotherapy. Recent randomized controlled studies have extended the knowledge on the frequency of side effects associated with biotherapy. More recently, novel targeted drugs, such as the mammalian target of rapamycin inhibitor everolimus and the multiple tyrosine kinase inhibitor sunitinib, have been introduced in the management of NETs. Although targeted drugs are generally well tolerated, with most adverse events being of mild to moderate severity and manageable, novel targeted drugs exhibit a distinct adverse event profile that warrants guidance for appropriate diagnostic and therapeutic management. This is particularly important given the widespread and potentially long-term use of everolimus in a broad spectrum of NETs and of sunitinib in pancreatic NETs. This review will focus on the most relevant toxicities associated with biotherapy and novel targeted drugs and on their management. For each drug class indication, administration and dosing schedule, most frequent adverse events, actions and dose adjustments for adverse events as well as their monitoring are presented. This review further covers the evaluation of treatment effect, patient information, drug interactions, and information on pregnancy.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- This 6-month, open, non-controlled, multicenter, dose-titration study evaluated the efficacy and safety of 28-day prolonged-release (PR) lanreotide in the treatment of carcinoid syndrome. Eligible patients had a carcinoid tumor with > or =3 stools/day and/or > or =1 moderate/severe flushing episodes/day. Six treatments of 28-day PR lanreotide were administered by deep subcutaneous injection. The dose for the first two injections was 90 mg. Subsequent doses could be titrated (60, 90, 120 mg) according to symptom response. Seventy-one patients were treated. Flushing decreased from a mean of 3.0 at baseline to 2.3 on day 1, and 2.0 on day 2, with a daily mean of 2.1 for the first week post-treatment (p < 0.05). Diarrhea decreased from a mean of 5.0 at baseline to 4.3 on day 1 (p < 0.05), and 4.5 on day 2, with a daily mean of 4.4 for the first week post-treatment (p < 0.001). Symptom frequency decreased further after the second and third injections, and reached a plateau after the fourth injection. By month 6, flushing and diarrhea had significantly decreased from baseline by a mean of 1.3 and 1.1 episodes/day, respectively (both p < or = 0.001); 65% of patients with flushing as the target symptom and 18% of diarrhea-target patients achieved > or =50% reduction from baseline. Median urinary 5-hydroxyindoleacetic acid and chromogranin A levels decreased by 24 and 38%, respectively. Treatment was well tolerated. 28-day PR lanreotide was effective in reducing the symptoms and biochemical markers associated with carcinoid syndrome.
