OBJECTIVE: Uterine sarcomas are a rare and heterogeneous group of malignancies that include different histological sub-types. The aim of this study was to identify and evaluate the impact of the different prognostic factors on overall survival and disease-free survival of patients with uterine sarcoma. METHODS: This international multicenter retrospective study included 683 patients diagnosed with uterine sarcoma at 46 different institutions between January 2001 and December 2007. RESULTS: The 5-year overall survival for leiomyosarcoma, endometrial stromal sarcoma, undifferentiated sarcoma, and adenosarcoma was 65.3%, 78.3%, 52.4%, and 89.5%, respectively, and the 5-year disease-free survival was 54.3%, 68.1%, 40.3%, and 85.3%, respectively. The 10-year overall survival for leiomyosarcoma, endometrial stromal sarcoma, undifferentiated sarcoma and adenosarcoma was 52.6%, 64.8%, 52.4%, and 79.5%, respectively, and the 10-year disease-free survival was 44.7%, 53.3%, 40.3%, and 77.5%, respectively. The most significant factor associated with overall survival in all types of sarcoma except for adenosarcoma was the presence of residual disease after primary treatment. In adenosarcoma, disease stage at diagnosis was the most important factor (hazard ratio 17.7; 95% CI 2.86 to 109.93). CONCLUSION: Incomplete cytoreduction, tumor persistence, advanced stage, extra-uterine and tumor margin involvement, and the presence of necrosis were relevant prognostic factors significantly affecting overall survival in uterine sarcoma. The presence of lymph vascular space involvement and administration of adjuvant chemotherapy were significantly associated with a higher risk of relapse.

Mezenchymálne tumory tela maternice a ovaria predstavujú širšiu skupinu, v ktorej došlo v ostatných rokoch k popisu nových jednotiek, k viacerým zmenám v klasifikácii (po prehodnotení histogenézy a vzájomných vzťahov medzi jednotkami) a k upresneniu poznatkov o biologickej povahe tumorov. Tento prehľad, ktorý vzhľadom na rozsah problematiky nemôže byť úplný, sa zameriava práve na prezentáciu novších poznatkov, ako sú: spresnená diagnostika biologickej povahy u hladkosvalových tumorov, stromálne tumory maternice a ich novšie varianty, UTROSCT (uterine tumor resembling ovarian sex cord tumor), PEC-ómy a PEC-ómová diferenciácia, biologická povaha skupiny „ovariálny fibróm-celulárny fibróm-mitoticky aktívny celulárny fibróm-fibrosarkóm“, sklerotizujúci stromálny tumor a myxóm ovaria. V prípade ovaria sú teda diskutované len lézie, ktorých origom nie je špecializovaná ovariálna stróma, nakoľko tumory zo špecializovaného mezodermu ovaria predstavujú ďalšiu rozsiahlu skupinu, ktorej popis vyžaduje osobitný prehľad.
In the large group of uterine and ovarian tumors, the knowledge was updated in recent years substantially. New entities were defined and changes in classification of the lesions were performed. This review is limited to updates, such as evaluation of uterine smooth muscle tumors, new variants of uterine stromal tumors, uterine tumors resembling ovarian sex-cord tumor (UTROSCT), perivascular epithelioid cell tumors (PEC-omas), ovarian fibroma and fibrosarcoma, sclerosing stromal tumor and myxoma. Group of tumors of specialized gonadal stroma is not discussed as it represents particular area and thus requires a separated review article.

Popísaný je neobvyklý prípad gastrointestinálneho stromálneho tumoru (GIST) s glandulárnou zložkou. Šlo o tumor gastrického fundu u 93-ročnej ženy. Histológia lézie bola tvorená diferen- covanou vretenobunkovou štruktúrou typického GIST-u, v ktorej boli difúzne prítomné z časti cystické žliazky. Kolumnárny epitel žliazok bol podobný pylorickému a foveolárnemu typu, s lo- žiskami intestinálnej metaplázie a miestami s dyspláziami. Stromálna zložka tumoru bola imuno- histochemicky pozitívna na CD117 (c-kit) a CD34, negatívne boli myoidné a neuroidné markery. Elektronmikroskopicky šlo o nediferencované vretenovité bunky. Sliznica a submukóza v blízkos- ti tumoru vykazovali fokálne známky gastritis cystica profunda so žliazkami podobnými ako vnú- tri tumoru. V histogenéze tumoru je predpokladaná kolízia GIST-u a gastritis cystica profunda.
A case of gastrointestinal stromal tumor (GIST) with an unusual glandular component is reported. The tumor was found in the gastric fundus of a 93-year-old woman. Histologically, the lesion showed a biphasic adenosarcoma-like structure. Typical low-grade spindle cell patterns of GIST were intermingled with numerous and partly cystic glands. The glandular epithelium had pyloric/foveolar-like appearance, with foci of intestinal metaplasia and low-grade dysplasia. The stromal component was immunoreactive for CD117 (c-kit) and CD34, and negative for myoid and neuroid markers. The ultrastructural examination found nondescript and undifferentiated spindle cells. The gastric mucosa and submucosa near the tumor contained a small area with features of gastritis cystica profunda, with glands similar to those present inside the tumor. Therefore, a collision of GIST and gastritis cystica profunda is suggested in the histogenesis of the lesion.
