- BACKGROUND: Patients with small intestinal neuroendocrine tumours (siNETs) usually present with advanced disease. Primary tumour resection without curative intent is controversial in patients with metastatic siNETs. The aim of this meta-analysis was to investigate survival after primary tumour resection without curative intent compared with no resection in patients with metastatic siNETs. METHODS: A systematic literature search was performed, using MEDLINE® (PubMed), Embase®, Web of Science, and the Cochrane Library up to 25 February 2021. Studies were included if survival after primary tumour resection versus no resection in patients with metastatic siNETs was reported. Results were pooled in a random-effects meta-analysis, and are reported as hazard ratios (HRs) with 95 per cent confidence intervals. Sensitivity analyses were undertaken to enable comment on the impact of important confounders. RESULTS: After screening 3659 abstracts, 16 studies, published between 1992 and 2021, met the inclusion criteria, with a total of 9428 patients. Thirteen studies reported HRs adjusted for important confounders and were included in the meta-analysis. Median overall survival was 112 (i.q.r. 82-134) months in the primary tumour resection group compared with 60 (74-88) months in the group without resection. Five-year overall survival rates were 74 (i.q.r. 67-77) and 44 (34-45) per cent respectively. Primary tumour resection was associated with improved survival compared with no resection (HR 0.55, 95 per cent c.i. 0.47 to 0.66). This effect remained in sensitivity analyses. CONCLUSION: Primary tumour resection is associated with increased survival in patients with advanced, metastatic siNETs, even after adjusting for important confounders.

Long-term survival of metastatic small intestine neuroendocrine tumors : a meta-analysis

- This meta-analysis aims to evaluate the long-term survival and prognostic factors in patients with metastatic small intestine neuroendocrine tumors (siNETs). Patients with siNETs usually present with advanced disease, limiting curative treatment options. The overall survival seems favorable compared to other cancers, but differences in terminology, lack of consistent coding, conflicting results from smaller cohorts, and recent developments of new treatment options make (reliable) survival data difficult to achieve. Nevertheless, accurate survival data are essential for many facets of health care. A systematic literature search was performed using MEDLINE®(PubMed), EMBASE®, Web of Science, and Cochrane Library up to June 30, 2021. Studies were included if the overall survival data in patients with metastatic siNETs were reported. The results were pooled in a random-effects meta-analysis and are reported as hazard ratios and 95% CIs. Subgroup analyses and meta-regression were performed to assess the observed heterogeneity and the impact of important prognostic factors. After screening 9065 abstracts, there were 23 studies, published between 1995 and 2021, that met the inclusion criteria, with a total of 8636 patients. The weighted 5- and 10-year overall survival was 67 and 37%, respectively. Meta-regression identified younger age and primary tumor resection to be associated with better prognosis. Subgroup analyses showed similar results. This study confirms that in an advanced, metastatic setting, the weighted 5- and 10-year overall survival reveal a favorable prognosis, improving over the last few decades. Meta-regression showed that age at diagnosis is an important prognostic factor.

Robot-assisted versus conventional laparoscopic adrenalectomy : Results from the EUROCRINE Surgical Registry
- 2022

Journal article (peer-reviewed)abstract
- Background: Adrenalectomy is routinely performed via the minimally invasive approach. Safety of adrenalectomy using the robot-assisted technique has been widely demonstrated by several series, but the literature is scarce regarding the comparison of conventional laparoscopic versus robot-assisted approach. We decided to carry out a multicenter study to compare clinical and surgical outcomes between laparoscopic and robotic adrenalectomy. Methods: This is a retrospective case-control study, including data from centers affiliated to the Surgical Registry EUROCRINE. Patients undergoing laparoscopic surgery for adrenal tumors and registered between 2015 and 2018 were included. Robot-assisted versus laparoscopic adrenalectomy was compared. All comparisons were carried out in terms of complication rate, conversion rate and duration of stay. Results: A total of 1,005 patients from 46 clinics underwent robotic or conventional laparoscopic adrenalectomy. Median age was 55 (interquartile range: 45−65) years. Robotic adrenalectomy was performed in 189 (18.8%) patients. According to Clavien-Dindo classification, complication rate was lower in the robotic surgery group (1.6% vs 16.5%, P <.001). Laparoscopic surgery and active hormonal status were significantly correlated with complications, both in univariate and multivariate analysis. There was no significant difference between laparoscopic and robotic surgery groups, in terms of conversion rate (2.1% vs 0.5%, respectively, P =.147). Duration of stay was shorter in the robotic adrenalectomy group (82.1% vs 28.8%, P <.001). Conclusion: Analysis of the EUROCRINE database supports that robotic adrenalectomy resulted in a lower complication rate and shorter duration of stay, compared with laparoscopic adrenalectomy. Granular data to support this is warranted.
