I-Adenocarcinoma yesisu

I-gastric adenocarcinoma iyisifo esibi esivela kwi-epithelium ye-glandular, eyenza i-stillary, tubular okanye i-acinar izakhiwo. Ngamanye amaxesha iiseli ezixhamlayo zibonakala ngathi zintlungu zesisu okanye isisu se-intestinal epithelium. Kwiimeko ezininzi, iintlobo ezahlukeneyo zichongiwe kwisakhiwo sakhe sengqondo seendawo ezahlukeneyo zesisu.

I-Adenocarcinoma yesisu iqukwa kwiqela elikhulu lomdlavuza wesisu. Oku kubandakanya izihlamba, ezibonakaliswa ngokulondolozwa kwiimilinganiselo ezihlukeneyo zesakhiwo - ukukwazi ukwenza iipilisi okanye izakhiwo ezinamafutha. I-grade-grade adenocarcinoma inexabiso elincinci lala maziko, apho kwezinye iimeko kunzima ukuzimisela.

I-Atypia yeeseli zesisu, njengommiselo, ukwanda ngokuhambelana nokunciphisa amandla okwakhiwa kwesakhiwo. I-Adenocarcinoma yesisu kwezinye iimeko ayivelisi i-mucus. Kukho umlinganiselo ongabalulekanga we-mucus kwi-lumen yeengqungquthela okanye kwii-cellular departments. Kwamanye amaxesha, i-adenocarcinoma yesisu ihamba ne-secrets. Kwiimvumba ezinjalo zingabikho ngaphandle kweeseli (kwi-stroma) kunye nefomu "ngamachibi" (amacu) kunye namaseli omhlaza atyantayo (adibaniswe ngendlela yeentlobo zeengqungquthela okanye amaqela). Olu hlobo lokufihla, njengomthetho, luboniswa ngee-tumors ezihluke kakhulu.

Olunye uhlobo lwe-secretion lubonakaliswa ngokuqokelelwa kweeseli zomhlaza kwi-cytoplasm ye- mucus. Ngexesha elifanayo, lichitha i-nucleus yabo, kunye ne "kricoid" cells cells. Olu hlobo lokufihla luphawu lwesifo se-tumors ephantsi. Kwiimeko ezininzi, kukho ukudibanisa kwemveliso ye-intracellular kunye ne-extracellular production.

I-Adenocarcinoma ingaba i-tubular, i-papillary, i-mucous. Kukho umhlaza we-ring-cell.

I-tumor ye-tubular ibonakaliswe izakhiwo ze-tubular ezixutywe kakhulu okanye zijikelezwe yi-stroma fibrotic. Iiseli ezixhamlayo zineqhekeza okanye i-cylindric shape, zivame ukutyhutyha ngenxa yokuqokelela kwimilo ekhulisiweyo ye-mucus.

Ukwakheka kwamapapilisi kumelwa ngamanzi amaninzi okanye amancinci anjengomunwe we-epithelium ene-fibrous base. Kwiimeko ezininzi, ukuhluma kwe-epithelium kwenzeka kwiipayipi okanye kwiingqungquthela zomzimba ezinjengeempilisi. Ngokwenene kwimeko nganye kunokwenzeka ukucacisa ukuphulwa okupheleleyo kwembalo yesiseko.

I-tumor mucosal ibonakaliswe ngokulondolozwa kwimiba yaloo mveliso ebalulekileyo ye-mucus, eyokuthi, ngokomthetho, ingafunyanwa ngeso iso.

I-Adenocarcinoma yesisu: unyango

Ukutyunjwa kwamanyathelo okwelapha kwenziwa ngokuxhomekeka kwisigaba kunye nendawo yokubunjwa kwesisu.

Uninzi lweziganeko zihambelana nobomi besigulane, ukwenzela ukuba kugcinwe oogqirha basuse ngokupheleleyo isisu okanye isisu kunye nesisu (ukuba i-tumor ikhona kwicandelo layo eliphezulu). Ukuba ukubunjwa kusekho kwinqanaba elincinane lomnyango, kunokwenzeka ukugcina inxalenye yesithathu yelungu.

Ukuze kuphuculwe usebenzelelo lwongenelelo olwenziwe ngophala kunye nokuba amathuba okuphilisa isigulane, i-radiotherapy okanye iikhomotherapy ziyakunikwa ngokwengeziwe emva kokungenelela. Ngokweziphumo zeengcali zonyango, i- radiotherapy (i-radiotherapy) kunye nezifundo ze-chemotherapy ziyakwandisa kakhulu amathuba okubuyiswa kwesigulane kunye nokunciphisa ukuvela kwakhona kwe-tumor formation.

Isigaba sesithathu semva yesifo somhlaza singaphathwa ngxaki enkulu. Nangona kunjalo, amanyathelo okwelapha anokwenzeka. Kwiimeko ezinjalo, njengomthetho, izifundo ze-chemotherapy zichazwe.
