dc.description.abstract Background. Gastrointestinal stromal tumors (GIST) represent 0.1-3% of all mesenchymal neoplasms of the gastrointestinal tract and giant gastric (GG) GIST are rare. Objective of the study. Study of clinical, histopathological and immunohistochemical features and treatment results of GG GIST. Material and Methods. 92 patients with GG GIST(c-kit(CD117)(+) treated between 2007-2019. Study group–14 patients with GG GIST, M:F=1.8:1, mean age-59.78±2.35(95%CI:54.69-64.87) years. Results. Surgical options: excision of gastric tumor-2(14,3%), gastric wedge resection-7(50%), partial gastrectomy-5(35,7%). The mean maximum size of tumors 23,69±0,81(95%CI:21,93-25,44)cm. Immunohistochemical phenotype: CD117(+)–14(100%), CD34(+)–12(85.7%), desmin(+)–3(21.4%), vimentin(+)–10(71.4%), S-100(+)–3(21.4%), SMA(+)–8(57.1%), NSE–2(14.3%). Mean number of mitoses–24.36±6.3(95%CI:10.65-38.06). Tumors with high mitotic count were registered more frequent than with low mitotic count–11(78.6%) vs. 3(21.4%)(p<0.05). Metastases at first presentation– 28.6%(n=4) cases. Complex treatment – surgical and target therapy with imatinib mesylate–14(100%) patients. Conclusion. GG GIST are rare, but possess a higher risk of progression. Complex treatment is the best curative option. Introducere. Tumorile gastrointestinale stromale (TGIS) reprezintă 0,1-3% din neoplaziile mezenchimale ale tractului digestiv. TGIS gastrice gigante (GG) se întâlnesc rar. Scopul lucrării. Analiza particularităților clinice, a aspectelor histopatologice, imunohistochimice și a rezultatelor tratamentului TGIS GG. Material și Metode. 92 de pacienți cu TGIS GG (c-kit(CD117)(+) operați între 2007-2019. Lotul de cercetare–14 pacienți cu TGIS GG, raportul femei:bărbați– 1:1,8, vârsta medie 59,78±2,35 ani. Rezultate. Volumul operațiilor: excizia tumorii peretelui gastric– 2(14,3%), rezecție gastrică limitată–7(50%), gastrectomie subtotală–5(35,7%). Dimensiunea maximă în medie a tumorilor 23,69±0,81 cm. Profilul imunohistochimic al tumorilor: CD117(+)–14(100%), CD34(+)–12(85,7%), desmină(+)–3(21,4%), vimentină(+)–10(71,4%), S-100(+)–3(21,4%), SMA– 8(57,1%), NSE–2(14,3%). Numărul mediu al mitozelor– 24,36±6,3(95%CI:10,65-38,06). Tumorile cu indice mitotic înalt au predominat asupra tumorilor cu indice mitotic redus– 11(78,6%) vs. 3(21,4%)(p<0,05). Metastaze la adresarea primară– 28,6%(n=4) cazuri. Tratament combinat – chirurgical și target terapie cu imatinib mesilat– 14(100%) pacienți. Concluzii. TGIS gastrice gigante sunt rare, dar frecvent cu risc înalt de progresare. Tratamentul combinat este opțiunea curativă optimă. en_US
