Pancreatic kenza

Pancreatic kenza chinhu akaipa neoplasm, aumba kubva masero achiumba rwatata. Vakawanda mhando kenza, izvo chinoita kuti kusvika 95% vose nyaya bundu uyu adenocarcinoma, iyo anova mukati rokuti exocrine rwatata. Adenocarcinoma - munhu akaipa nebundu kukanganisa glandular zvinyama muviri. Zvisinei, havasi vose nyaya pancreatic kenza - inongova adenocarcinoma yakadaro. Mune zvimwe zviitiko, bundu hwapedyo kubva anonzi masero islet, uye naizvozvo semhosva yakakura neuroendocrine bundu. Zviratidzo uye zviratidzo anokonzera nokufungirana kenza kuvimba nzvimbo bundu, ayo ukuru uye mhando rejira, ayo mufananidzo. Kazhinji, pancreatic kenza zviratidzo zvinosanganisira abdominal marwadzo, marwadzo ari yakaderera shure, uye kana bundu anorumanya iri bile mutsinga dzinofamba nemukaka, jaundice. Uyezve, pangava kuchikosha uremu, kuvaviwa, kuora mwoyo, rikwanise tsinga thrombophlebitis (Trousseau kuti chiratidzo), chiratidzo Courvoisier nevamwe vazhinji.

Mune chepamusoro zvikuru zvinouraya nekenza pancreatic kenza nechivimbo akabata rinokudzwa chechina kukonzera rufu pavanhu navakadzi, kuva chaikonzera anenge 6% vose kufa nekenza. Inenge zvikamu zvitatu zvose pancreatic nekenza munguva musoro kana mutsipa kenza, 15 kusvika 20 muzana namamota kukura shwanu muviri zvakananga, uye zvakare 5 kusvika 10 muzana muswe wayo kuoneka.

Mabatirwo pancreatic kenza zvakaoma zvakakwana, saka sei rokuongorora bundu iri tanga kwazvo, basa rakaoma chaizvo. Uyezve, maererano nenhamba, vanopfuura hafu varwere vose panguva zvokuongorora "pancreatic kenza" vatakuri vakanga metastatic namamota, uye muna 26 muzana lesion yaiitwa remunharaunda node nodes. The hama kupona varwere rokutanga gore pashure chirwere, "pancreatic kenza" ndiyo muzana 26 chete. Zvisinei, zvakafanana-gore mashanu mwero iri kunyange kudzika panguva kungotaura 6%.

Zvinofanira kucherechedzwa kuti vose pancreatic anomera vari adenocarcinomas 80% ductal epithelium. 2 chete muzana namamota ari exocrine rwatata vari benign.

Ishoma siyana pancreatic histological kenza mhando anosanganisira mapundu akadai hofori muchitokisi carcinoma, glandular, squamous sero carcinoma, mikroglandulyarnaya adenocarcinoma, mucoid carcinoma, cystadenocarcinoma, papillary cystic carcinoma, cystadenocarcinoma acinar, atsinoznokletochnaya cystadenocarcinoma. Very kashoma zvinoitika kuti murwere yakatanga pancreatic bundu connective tishu. Vakawanda mhando kenza ndiyo rwekenza yelymphoma rwatata.

Kazhinji, asi metastasis wokutanga pancreatic kenza kunoguma remunharaunda node nodes, chiropa uye zvishoma kakawanda zvemapapu. Mukuwedzera, bundu anogona kukura zvakananga kupinda zvomukati, izvo akaiswa munzvimbo peritoneum pedyo nesosredstvenno shwanu, i.e. kuti dumbu, duodenum uye muura. Uyezve, pancreatic kenza anogona metastasize peritoneally chero pose riri abdominal mhango. Somugumisiro, anogona kuva ascites (norukandwe), uye ndizvo chaizvo, rima chaizvo uye nezvakaipa chiratidzo. Pancreatic kenza anogona metastasize kuti ganda uye kuti achange kuonekwa muchimiro anorwadza nodules. Mune zvose izvi anomera dzakadaro kashoma kupa metastases kune pfupa.
