Esophageal cancer has a poor overall prognosis and is frequently diagnosed at a late stage. Conventional treatment for metastatic esophageal cancer involves chemotherapy and radiation. Local disease control plays a significant role in improving survival. Endoscopic spray cryotherapy is a novel modality that involves freezing and thawing to produce local ablation of malignant tissue via ischemic mechanisms. Spray cryotherapy has been shown to be effective, particularly for early T-stage, superficial esophageal adenocarcinomas. We present the case of a 72-year-old-male with locally recurrent stage IV esophageal adenocarcinoma and long-term survival of 7 years to date, with concurrent chemoradiation and serial cryoablation. He remains asymptomatic and continues to undergo chemotherapy and sequential cryoablation. The findings highlight the long-term safety and efficacy of cryotherapy in combination with chemoradiation, and suggest that cryoablation may have an additive role in the treatment of advanced stage esophageal adenocarcinoma.

<P>Mesoporous particles are emerging as multifunctional biomaterials for imaging and drug delivery in several disease models, including cancer. We developed PEGylated α-Gd<SUB>2</SUB>(MoO<SUB>4</SUB>)<SUB>3</SUB> marigold flower-like mesoporous particles for the purpose of drug delivery and, more specifically, evaluated their ability to deliver curcumin. The obtained mesoporous particles significantly conjugated the curcumin particles on their surfaces by inducing the formation of curcumin nanoparticles. <I>In vitro</I> studies of the PEGylated mesoporous particles filled with curcumin demonstrated that these particles could considerably facilitate the continuous and sustained release of curcumin into the cytoplasm and nucleus. As a result, the intracellular release of curcumin can inhibit proliferation in two human pancreatic cancer cell lines: MIA PaCa-2 and PANC-1. Additionally, the particles showed the increased inhibition of pIKKα, pIKKα/β and NF-κB–DNA binding activity as compared to pure curcumin. The curcumin conjugated mesoporous particles are concentrated in the cytoplasm and nucleus of the treated cancer cell lines. Consequently, these mesoporous particles are an effective method for drug delivery that can cross the biological barriers of the body targeting the cellular nucleoplasm.</P> <P>Graphic Abstract</P><P>The advantage of PEGylated α-Gd<SUB>2</SUB>(MoO<SUB>4</SUB>)<SUB>3</SUB> marigold-like mesoporous flowers with curcumin is to facilitate nuclear localization and release of the conjugated drug, triggering the signal within the nucleoplasm. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c3dt52692e'> </P>

Purpose Appendiceal tumors are a heterogeneous group of diseases that include typical neuroendocrine tumors (TNET), goblet cell carcinoids (GCC), and atypical GCC. Atypical GCC are classified into signet-ring cell cancers (SRCC) and poorly differentiated appendiceal adenocarcinoids. The prognosis and management of these diseases is unclear because there are no prospective studies. The aim of this study is to assess the characteristics and outcome of appendiceal TNET, GCC, and SRCC patients. Materials and Methods Appendiceal TNET, GCC, and SRCC patients diagnosed between 1973 and 2011 were identified in the Surveillance Epidemiology and End Results (SEER) database. Demographics, type of surgery, and clinicopathologic characteristics were collected. Survival functions were estimated by the Kaplan-Meier method, and log-rank test was used to assess the difference in overall survival (OS) among the three histologies. Results The SEER database yielded 1,021 TNET patients, 1,582 with GCC, and 534 SRCC patients. TNET presented at a younger age (p < 0.001). Patients with SRCC presented with advanced stage disease (p < 0.001). The median OS (mOS) for GCC and TNET patients was not reached; mOS for SRCC was 24 months. Multivariate analysis stratified for stage revealed significantly longer survival for TNET and GCC than SRCC (p < 0.001). Conclusion This is the largest report to date for appendiceal neuroendocrine tumor patients, suggesting a spectrum of diseases with different characteristics and outcomes. In this report, we present a treatment approach for this complex spectrum of disease, based on the experience of Ohio State and Emory Universities investigators.

Background/Aims: Endoscopic resection has become the preferred treatment approach for select early esophageal adenocarcinoma(EAC); however, the epidemiology of early stage disease has not been well defined. Methods: Surveillance Epidemiology and End Results (SEER) data were analyzed to determine age-adjusted incidence rates amongmajor epithelial carcinomas, including EAC, from 1973 to 2017. The percent change in incidence over time was compared according totumor subtype. Early T-stage, node-negative EAC without metastasis was examined from 2004 to 2017 when precise T-stage data wereavailable. Results: The percent change in annual incidence from 1973 to 2017 was 767% for EAC. Joinpoint analysis showed that the average annualpercent change in EAC from 1973 to 2017 was 5.11% (95% confidence interval, 4.66%−5.56%). The annual percent change appearedto plateau between 2004 and 2017; however, early EAC decreased from 2010 to 2017, with an annual percent change of −5.78%. Conclusions: There has been a 7-fold increase in the incidence of EAC, which was significantly greater than that of the other major epithelialmalignancies examined. More recently, the incidence of early EAC has been decreasing. Approximately one in five patients hasnode negative, potentially resectable early stage disease.
