Interventional Radiology Approaches for Liver Metastases from Thyroid Cancer: A Case Series and Overview of the Literature

BACKGROUND: Liver metastases (LMs) from thyroid cancer (TC) are relatively uncommon in clinical practice and their management is challenging. Interventional radiology loco-regional treatments (LRTs), including radiofrequency ablation (RFA) and trans-arterial chemoembolization (TACE), have been successfully employed to treat LMs from various types of cancer. METHODS: We analyzed the role of LRTs in the management of unresectable LMs from differentiated and medullary TCs performed at our institution from 2015 to 2020. A review of the available English literature regarding this topic was also performed. RESULTS: Six hepatic LRTs were performed in 4 TC patients with LMs, in 2 cases after the start of treatment with a tyrosine kinase inhibitor (TKI). A partial response was obtained in 2 patients; the diameter of the largest targeted lesion was 18 mm in both of them. The remaining procedures were performed on larger lesions and a stable disease was achieved in all but one case. Acute LRT-related complications were transient and mild. In literature, the largest studies were focused on TACE in LMs from MTC, showing good tolerance and remarkable disease control, especially in case of limited liver tumour involvement. CONCLUSION: LRTs for LMs represent a valuable option for the treatment of metastatic TC in case of isolated hepatic progression or for symptoms relief, also after the start of TKI treatment as part of a multimodal approach. The best disease control is obtained when hepatic metastatic burden is limited. These procedures are generally well tolerated; however, a cautious multidisciplinary selection of the candidates is mandatory

Employment among Childhood Cancer Survivors: A Systematic Review and Meta-Analysis

To date, there are heterogeneous studies related to childhood cancer survivors’ (CCS) employment rates. Given the importance of this topic, we aimed to perform a systematic review and meta-analysis to investigate the prevalence of employment among CCS and to examine its association with socio-demographic and clinical factors. We followed the PRISMA guidelines to search for pertinent articles in relevant electronic databases. Eighty-nine articles comprising 93 cohorts were included. The overall prevalence of employment was 66% (CI: 95% 0.63–0.69). Subgroup meta-analyses showed that lower rates were found for central nervous system tumor survivors (51%, CI: 95% 0.43–0.59), and for CCS treated with cranial-radiotherapy (53%, CI: 95% 0.42–0.64) or haematopoietic stem-cell transplantation (56%, CI: 95% 0.46–0.65). The studies conducted in Asia highlighted employment rates of 47% (CI: 95%, 0.34–0.60). Univariate meta-regressions identified the following socio-demographic factors associated with higher rates of employment: a female gender (p = 0.046), a higher mean age at the time of investigation (p = 0.00), a longer time since diagnosis (p = 0.00), a higher educational level (p = 0.03), and a married status (p = 0.00). In conclusion, this systematic review and meta-analysis provides evidence that two-thirds of CCS are employed worldwide. Identifying vulnerable groups of CCS may allow for the design of multidisciplinary support strategies and interventions to promote employment in this population

Endocrine activities of cortistatin-14 and its interaction with GHRH and ghrelin in humans.

Cortistatin (CST)-14, a neuropeptide with high homology with somatostatin (SS)-14, binds all sst subtypes but, unlike SS, also ghrelin's receptor. In six normal adults, we studied the effects of CST-14 or SS-14 administration (2.0 micro g/kg/h iv) on: 1) GH and insulin secretion; 2) the GH response to GHRH (1.0 microg/kg i.v.); and 3) the GH, prolactin (PRL), ACTH, cortisol, insulin, and glucose responses to ghrelin (1.0 microg/kg i.v.). CST-14 inhibited GH and insulin secretion (P < 0.01) to the same extent of SS-14. The GH response to GHRH was similarly inhibited (P < 0.01) by either CST-14 or SS-14. Ghrelin released more GH than GHRH (P < 0.01); these responses were similarly inhibited (P < 0.05) by either CST-14 or SS-14, that made ghrelin-induced GH rise similar to that after GHRH alone. Neither CST-14 nor SS-14 modified PRL, ACTH, or cortisol responses to ghrelin. The inhibitory effect of CST-14 and SS-14 on insulin was unaffected by ghrelin that, in turn, reduced insulin secretion per se (P < 0.01). Ghrelin increased glucose levels (P < 0.05); CST-14 and SS-14 did not modify this effect. Thus, CST-14 inhibits both basal and stimulated GH secretion in humans to the same extent of SS-14. The GH-releasing activity of ghrelin seems partially resistant to CST-14 as well as SS-14. CST-14 and SS-14 do not affect PRL and ACTH secretion but, like ghrelin, inhibit insulin secretion; the ghrelin-induced inhibition is not additive with that of CST-14 or SS-14, suggesting a common mechanism of action on beta cell secretion
