Med Hypotheses 2021; 150:110573. [PMID: 33799159 DOI: 10.1016/j.mehy.2021.110573] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 01/28/2021] [Accepted: 03/13/2021] [Indexed: 11/15/2022]
Abstract
Some studies state that laryngeal squamous cell carcinoma (LSCC) is associated with possible direct tumor cell seeding to percutaneous endoscopic gastrostomy (PEG) site. However, there is a lack of experimental proof that LSCC tumor tissue can adhere and grow in distant sites. Therefore, we aimed to investigate the growth pattern of LSCC implants on chicken embryo chorioallantoic membrane (CAM) and evaluate possible associations between clinical course of the disease and behavior of experimentally implanted LSCC tumors. Our results show that implanted LSCC tissue survives on CAMs in 95% of cases while retaining essential morphologic characteristics and proliferative capacity of the original tumor. We identified the increased CAM vascularization, an infiltrative growth pattern of the implant and formation of distant isolated metastatic nodes on the CAMs. LSCC tumors with worse differentiation degree (G2 or G3) adhered to the experimental CAMs significantly better than G1. These results facilitate the understanding of tumor biology and allow hypothetisezing that dissemination and direct implantation of LSCC cells into the stomal wall during the pull PEG procedure might be possible.

Metastasis to gastrostomy sites from upper aerodigestive tract malignancies: a systematic review and meta-analysis. Gastrointest Endosc 2020; 91:1005-1014.e17. [PMID: 31926149 DOI: 10.1016/j.gie.2019.12.045] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2019] [Accepted: 12/26/2019] [Indexed: 02/08/2023]
Abstract
BACKGROUND AND AIMS Metastasis to the gastrostomy site in patients with upper aerodigestive tract (UADT) malignancies is a rare but devastating adverse event that has been poorly described. Our aim was to determine the overall incidence and clinicopathologic characteristics observed with development of gastrostomy site metastasis in patients with UADT cancers. METHODS This was a systematic review and meta-analysis of 6138 studies retrieved from Medline, EMBASE, CINAHL, and the Cochrane Register after being queried for studies including gastrostomy site metastasis in patients with UADT malignancies. RESULTS The final analysis included 121 studies. Pooled analysis showed an overall event rate gastrostomy site metastasis of .5% (95% confidence interval [CI], .4%-.7%). Subgroup analysis showed an event rate of .56% (95% CI, .40%-.79%) with the pull technique and .29% (95% CI, .15%-.55%) with the push technique. Clinicopathologic characteristics observed with gastrostomy site metastasis were late-stage disease (T3/T4) (57.8%), positive lymph node status (51.2%), and no evidence of systemic disease (M0) (62.8%) at initial presentation. The average time from gastrostomy placement to diagnosis of metastasis was 7.78 ± 4.9 months, average tumor size on detection was 4.65 cm (standard deviation, 2.02), and average length of survival was 7.26 months (standard deviation, 6.23). CONCLUSIONS Gastrostomy site metastasis is a rare but serious adverse event that occurs at an overall rate of .5%, particularly in patients with advanced-stage disease, and is observed with a very poor prognosis. These findings emphasize a need for clinical practice guidelines to include a regular assessment of the PEG site and highlight the importance of detection and management of gastrostomy site metastasis by the multidisciplinary care oncology team.
