A Case of Gastric Neuroendocrine Carcinoma with Rapid Progression.

A Case of Gastric Neuroendocrine Carcinoma with Rapid Progression. Intern Med. 2020 Feb 19;: Authors: Iwamoto M, Gotoda T, Noda Y, Esaki M, Moriyama M, Yoshida N, Takayama T, Kobayashi H, Masuda S Abstract As gastric neuroendocrine carcinoma (NEC) is a rapidly growing cancer, most cases are diagnosed at advanced stages. We herein report a 74-year-old woman with an early-stage gastric NEC whose history included endoscopic submucosal dissection treatment for three early-stage gastric cancer lesions five years prior to the current presentation. We also describe the changes observed over time. An endoscopic examination during follow-up revealed an NEC (measuring 6 mm) in the gastric vestibule, for which distal gastrectomy was performed. Four months before surgery, the carcinoma exhibited specific morphological changes and lymphovascular invasion (despite the tumor being stage 1), suggesting a high-grade NEC.

AbstractNearly 50% of primary lung carcinoma patients present with distant metastasis at their first visit. However, gastrointestinal tract (GIT) metastasis is an infrequent impediment. Herein, we report a case of progressive dysphagia and epigastralgia as an initial manifestation of recurrence as gastric metastasis of primary lung squamous cell carcinoma (SCC) after curative surgery. A 64 ‐year‐old man was diagnosed with primary lung SCC of the right lower lobe, and underwent thoracoscopic lower lobectomy. One year after lobectomy, computed tomography (CT) scan showed a gastric fundal mass located in the gastric cardi...

CONCLUSIONS: KIF22 protein level was negatively correlated with prognosis. KIF22 knockdown might inhibit proliferation and metastasis of GC cells via the MAPK-ERK signaling pathway. PMID: 32187050 [PubMed - as supplied by publisher]

Conclusion: Tumour size, depth of invasion, morphological classification and blood vessel invasion were predictive risk factors for LNM in EGC. We propose that EGC patients with those risk factors should be accepted gastrectomy with LN dissection.

ConclusionsThis study showed that double-flap valvuloplastic esophagogastrostomy is safe and feasible for reconstruction after LEPG for Siewert type II esophagogastric junction carcinoma. Moreover, the TDF method is a simple and useful technique that offers a shorter operative time and lower morbidity compared to the CDF technique.

ConclusionRisk-reducing total gastrectomy remains the best clinical management for patients with hereditary diffuse gastric cancer harboring a  germline, pathogenicCDH1 variant. In our series, intramucosal carcinoma foci were found in the great majority (89.5%) ofCDH1 carriers.

AbstractPurposeWe aimed to evaluate the prognostic impact of pulmonary dysfunctions and their relationships with other possible prognostic factors, especially sarcopenia, in elderly patients with gastric carcinoma (GC).MethodsIn total, 402 elderly GC patients ( ≥ 75 years) who underwent radical gastrectomy were retrospectively reviewed. Restrictive and obstructive pulmonary dysfunction were defined as %VC

Conclusion: Nivolumab has the potential to lead to R0 resection for patients with peritoneal carcinomatosis gastric cancer. To our knowledge, this is the first report of successful conversion surgery after nivolumab-related chylous ascites.

Conclusions: Patients with GSRC had a similar prognosis to those with NGSRC. The proposed nomogram allowed a relatively accurate survival prediction for operable GA patients after gastrectomy.

Conclusions: Postoperative morbidity, including SSI rates, did not significantly increase in patients undergoing TLDG without prophylactic antibiotic use. A large prospective randomized trial is warranted to reappraise the efficacy of prophylactic antibiotic use in patients undergoing TLDG. PMID: 31897347 [PubMed]
