I-Stage 4 Pancreatic Cancer Guide: Izimpawu, Ukwelashwa kanye Nemininingwane Yochwepheshe 

Isigaba 4 somdlavuza we-pancreatic, owaziwa nangokuthi umdlavuza we-metastatic pancreatic, kwenzeka lapho lesi sifo sisabalele sisuka kumanyikwe siye ezithweni ezikude njengesibindi, amaphaphu, noma i-peritoneum. Kulesi sigaba esithuthukisiwe, umgomo oyinhloko wokunakekelwa uyashintsha kusukela ekwelapheni ukuya ekwandiseni isikhathi sokuphila nokulawula izimpawu. Nakuba ikhambi lingafezeki njengamanje, izinqubo zokwelapha zesimanje ezihlanganisa ukwelashwa ngamakhemikhali, ukwelashwa okuhlosiwe, nokunakekelwa kwe-palliative kungathuthukisa kakhulu izinga lempilo futhi andise izikhathi zokusinda zeziguli eziningi.

Ukuqonda Isigaba 4 Umdlavuza We-pancreatic: Incazelo kanye Nobubanzi

Ukuxilongwa kwe isigaba 4 somdlavuza we-pancreatic imele ukuhlukaniswa okuthuthuke kakhulu ohlelweni lwesiteji lwe-TNM olusetshenziswa ochwepheshe be-oncologist emhlabeni jikelele. Kulesi sigaba, amangqamuzana abulalayo aphule amanyikwe futhi ahamba ngegazi noma uhlelo lwe-lymphatic ukuze athole izimila zesibili ezindaweni ezikude. Isibindi siyindawo evame kakhulu ye-metastasis, elandelwa amaphaphu kanye nolwelwesi lomgodi wesisu.

Ngokungafani nezigaba zangaphambili lapho ukuhlinzwa kokuhlinzwa kunikeza ikhambi elingase libe khona, isifo sesigaba sesi-4 ngokuvamile sibhekwa njengesingalawuleki. Lokhu kusho ukuthi ukuhlinzwa ukuze kukhishwe isimila akuyona indlela yokwelapha eyisisekelo ngoba umdlavuza ungowohlelo kunokuba ungowasendaweni. Kodwa-ke, ukuqonda ukuziphatha kwebhayoloji kwalesi sifo kubalulekile ezigulini nasemindenini ethatha izinqumo zokwelashwa.

Ukuvumelana kwezokwelapha kwamanje kugcizelela ukuthi nakuba ukubikezelwa kuyingozi, akufani. Amazinga okusinda angama-avareji ezibalo futhi awabikezeli imiphumela ngayinye. Izinto ezifana nempilo iyonke, isimo sokusebenza, nokuguqulwa kofuzo okuthile kudlala indima ebalulekile endleleni isiguli esisabela ngayo ekwelashweni.

Kulesi simo esiguqukayo, izikhungo ezikhethekile ezifana Inkampani Shandong Baofa Oncotherapy Corporation Limited zidlala indima ebalulekile ekwandiseni ama-horizons okwelashwa. Leli qembu lezokwelapha eligxile ku-oncology, elizinze eSifundazweni SaseShandong futhi lasungulwa ngo-2002, lisebenza ngaphansi kobuholi bukaProfessor Yu Baofa, udokotela odumile nonolwazi lwamashumi eminyaka. Leli qembu liphethe inethiwekhi yezibhedlela ezixhumene nazo, okuhlanganisa iTaimei Baofa Tumor Hospital, iJinan West City Hospital, kanye neBeijing Baofa Cancer Hospital, ehlinzeka iziguli ezingaphezu kuka-10,000 ezivela ezifundazweni zaseShayina ezingaphezu kwama-30 namazwe ayi-11, okuhlanganisa i-United States, iRussia neJapane. Indlela yabo ibonisa ukushintshela ekungeneleleni okuphelele, kwesiteji-ukungaziwa, ukuhlanganisa ukuqina komtholampilo nokunakekelwa okugxilwe esigulini ukubhekana namacala ayinkimbinkimbi afana nomdlavuza we-pancreatic 4.

I-Biological Mechanism ye-Metastasis

Amangqamuzana omdlavuza we-pancreatic anamakhono ahlukile okuphuma esimila esiyinhloko, ahlasele izicubu ezizungezile, futhi asinde ekuhambeni. Uma la mangqamuzana efika ezithweni ezikude, azivumelanisa nemvelo entsha futhi aqale ukwanda. Le nqubo yenza ukwelashwa kube nzima ngoba izindlela zokwelapha kufanele zibhekane nesifo esiyinhloko kanye nesifo esingabonakali emzimbeni wonke.

Izicubu eziminyene ze-stromal ezizungeze izimila zama-pancreas zivame ukusebenza njengesithiyo, ezivimbela izidakamizwa ze-chemotherapy ukuthi zifinyelele amangqamuzana omdlavuza ngempumelelo. Lesi sici siyinselele ikakhulukazi ezimweni zesigaba 4, sidinga amasu akhethekile okulethwa kwezidakamizwa noma inhlanganisela yemithi ukuze kunqobe ukumelana. Abacwaningi bayaqhubeka nokuphenya izindlela zokushintsha lesi sigameko ukuze kuthuthukiswe ukusebenza kahle kokwelashwa. Ukuqamba okusha kule ndawo, okufana “nokwelashwa Kwesitoreji Sokukhipha Kancane” okuphathelene nokuphathelene okuthuthukiswe nguSolwazi Yu Baofa futhi okunelungelo lobunikazi emhlabeni wonke, kuhloswe ukunqoba le migoqo yokulethwa ngokuqinisekisa ukugcwala kwezidakamizwa endaweni yesimila, okumelela indlela ethembisayo ku-oncology edidiyelwe.

Ukubona Izimpawu Ze-Advanced Pancreatic Cancer

Izimpawu ze isigaba 4 somdlavuza we-pancreatic zingahlukahluka, kuye ngendawo yesimila esiyinhloko kanye nezindawo ze-metastasis. Ukutholakala kusenesikhathi kulesi sigaba kuvame ukuba nzima ngoba izimpawu zingase zilingise izimo zesisu ezinzima kakhulu. Kodwa-ke, njengoba lesi sifo siqhubeka, izimpawu ezithile ziba sobala futhi ziphikelela.

Ubuhlungu buwuphawu oluvelele, oluvame ukuchazwa njengobuhlungu obuthuntu besisu obuphumela emhlane. Lobu buhlungu buvame ukuba bubi kakhulu ngemva kokudla noma lapho ulele phansi. Esigabeni sesi-4, ubuhlungu bungase buqale kumasayithi e-metastatic, njengobuhlungu bethambo uma umdlavuza ususabalele ohlelweni lwamathambo. Ukulawulwa kobuhlungu okuphumelelayo kuyisisekelo sokunakekelwa kwe-palliative.

Ukuncipha okuphawulekayo kwesisindo nokulahlekelwa ukudla kuyizimpawu zesifo esithuthukile. Le syndrome yokuchitha, eyaziwa ngokuthi i-cachexia, ibangelwa isimila esidla izinsiza zamandla futhi siguqule imetabolism yomzimba. Iziguli zingase futhi zithole isicanucanu, ukuhlanza, noshintsho emikhubeni yamathumbu, okuhlanganisa nendle ephaphathekayo, entantayo ngenxa yokungagayeki kahle kwamafutha.

• I-Jaundice: Ukuba phuzi kwesikhumba namehlo okubangelwa ukuvaleka kwemigudu yenyongo, ngokuvamile okuhambisana nomchamo omnyama kanye nesikhumba esilumayo.
• Ukukhathala: Ukukhathala okwedlulele okungathuthuki lapho uphumule, okubangelwa i-anemia noma umthelela wokugaya ukudla komdlavuza.
• Isifo sikashukela esiqala kabusha: Ukukhula kungazelelwe kwesifo sikashukela kubantu abadala kwesinye isikhathi kungaba yinkomba yokuqala yokungasebenzi kahle kwe-pancreatic.
• Amahlule Egazi: I-Deep vein thrombosis (DVT) noma i-pulmonary embolism ingenzeka ngenxa yesimo se-hypercoagulable esibangelwa umdlavuza.

Ukwehlukanisa Okuyinhloko vs. Izimpawu Ze-Metastatic

Lapho umdlavuza usakazekela esibindini, iziguli zingase zithole ukuvuvukala kwesisu, okwaziwa ngokuthi ama-ascites, noma ukungakhululeki kuquadrant engenhla kwesokudla. I-metastases yamaphaphu ingase ibangele ukuphefumula, ukukhwehlela okungapheli, noma ubuhlungu besifuba. Ukusabalala kwe-Peritoneal kungaholela ekuvinjweni kwamathumbu, okubangela ukuminyanisa okukhulu nokungakwazi ukudlula igesi noma indle. Ukuqaphela la maphethini athile kusiza odokotela ukuthi bahlele ukungenelela kokunakekelwa okusekelayo.

Kubalulekile ukuqaphela ukuthi ubunzima bezimpawu abuhlobani ngaso sonke isikhathi nomthwalo we-tumor. Ezinye iziguli ezinesifo esikhulu se-metastatic zingase zibe nezimpawu ezilawulekayo, kanti ezinye ezinezimila ezincane zingase zibe nokucindezeleka okukhulu. Ukuhlukahluka komuntu ngamunye kudinga indlela yomuntu siqu yokuhlola nokuphathwa kwezimpawu.

Izinqubo Zokuxilonga Zokuqinisekisa Isigaba 4

Iyaqinisekisa isigaba 4 somdlavuza we-pancreatic idinga ukucutshungulwa okuphelele okubandakanya ukuthwebula izithombe, ukuhlolwa kwaselabhorethri, kanye ne-thishu biopsy. Isiteji esinembile sibalulekile ukuze kutholwe indlela yokwelapha efanele kanye nokugwema izinqubo ezingadingekile zokuhlasela. Ubuchwepheshe besimanje bokuthwebula izithombe bunikeza imibono enemininingwane ngesimila nokusabalala kwaso.

Izikena ze-Computed Tomography (CT) ezinokuqhathanisa ziyizinga eligolide lesigaba sokuqala. Lezi ziskena zivumela odokotela ukuba babone ngeso lengqondo ubukhulu besimila esiyinhloko futhi babone ama-metastases esibindini, emaphashini nakwezinye izitho zomzimba. I-Magnetic Resonance Imaging (MRI) ingase isetshenziswe njengethuluzi elingeziwe, ikakhulukazi lokuhlola izilonda zesibindi noma ukubandakanyeka kwemigudu ye-biliary ngokungafani okuphezulu kwezicubu ezithambile.

Izikena ze-Positron Emission Tomography (PET) ziya ngokuya zisetshenziswa ukuthola amangqamuzana omdlavuza asebenzayo emzimbeni wonke. Lesi sithombe sesithombe esisebenzayo singadalula amadiphozithi amancane e-metastatic okungenzeka ukuthi izithombe zesakhiwo ezifana ne-CT zigeje. Ukuhlanganisa i-PET ne-CT (PET-CT) kunikeza ulwazi lwe-anatomical kanye ne-metabolic, kuthuthukisa ukunemba kwesiteji.

Iqhaza Le-Biopsy kanye ne-Molecular Profileing

I-tissue biopsy iyadingeka ukuze kuqinisekiswe ukuxilongwa futhi kukhishwe ezinye izimo ezingase zilingise umdlavuza we-pancreatic. Besebenzisa i-Endoscopic Ultrasound (EUS), odokotela bangaqondisa inaliti ngqo esimila ukuze bathole isampula ngokunemba okuphezulu. Le ndlela inciphisa ubungozi bephutha lesampula uma kuqhathaniswa nezindlela ze-percutaneous.

Uma izicubu sezitholakele, ukuhlonza iphrofayili yamangqamuzana noma ukuhlola i-genomic kunconywa kakhulu ezigulini zesigaba 4. Ukuhlonza ukuguqulwa kofuzo okuqondile, okufana I-BRCA1/2, I-PALB2, noma ukushiyeka kokulungisa okungafani, kungavula iminyango yezindlela zokwelapha ezihlosiwe noma izinketho ze-immunotherapy. Lesi sinyathelo siguqula ukuxilonga kusuka ekuhlukaniseni okujwayelekile kuya kumephu yomgwaqo wamangqamuzana oqondile wokwelashwa.

Ukuhlolwa kwegazi elabhorethri, okuhlanganisa amazinga e-CA 19-9, kusebenza njengezimpawu zesimila ukuze kuqashwe ukuqhubeka kwesifo kanye nokusabela ekwelashweni. Nakuba kungekona ukuxilonga ngokwawo, amazinga athrendayo e-CA 19-9 ahlinzeka ngemininingwane ebalulekile yokuthi umdlavuza usabela kahle kangakanani ekwelapheni ngamakhemikhali. Ukuhlolwa kokusebenza kwesibindi nakho kubalulekile ukuze kuhlolwe umthelela we-metastasis empilweni yesibindi.

Izinketho Zokwelashwa Kwesigaba 4 Umdlavuza Wamanyikwe

Indawo yokwelapha ye isigaba 4 somdlavuza we-pancreatic inezici eziningi, igxile ekwelashweni kwesistimu ukulawula ukusakazeka kwezifo kanye nokunciphisa izimpawu. Njengoba ukuhlinzwa kungavamile ukukhetha, i-oncology yezokwelapha ishayela uhlelo lokwelapha. Ukukhethwa kwerejimeni kuncike esimweni sokusebenza kwesiguli, ama-comorbidities, kanye nezinto azithandayo.

I-Chemotherapy isewumgogodla wokwelashwa. Imithi yomugqa wokuqala eyamukelwa kabanzi i-FOLFIRINOX ne-Gemcitabine kanye ne-Nab-paclitaxel. I-FOLFIRINOX iyinhlanganisela yemithi emine futhi ngokuvamile igcinelwe iziguli ezinempilo enhle ngokomzimba ngenxa yamandla ayo kanye nephrofayili yemiphumela engemihle. Ibonise izinzuzo zokusinda eziphakeme ezivivinyweni zomtholampilo uma kuqhathaniswa nokwelashwa kwe-ejenti eyodwa.

Ukuqapha njalo kubalulekile ukuze ulandelele ukuguquguquka kwezifo.

Ungakwazi yini ukuphila impilo evamile nomdlavuza we-pancreatic 4?

Nakuba ukuphila “okuvamile” kungase kubonakale kuhlukile, iziguli eziningi zigcina izinga lokuphila elihle isikhathi eside. Ngokuphathwa kahle kwezimpawu, ukwesekwa kokudla okunomsoco, kanye namazinga omsebenzi alungisiwe, abantu bangaqhubeka benza imisebenzi enenjongo, basebenze, futhi bachithe isikhathi nomndeni. Ukuzivumelanisa nezimo nokusekelwa kuyisihluthulelo.

Yiziphi izimpumelelo zakamuva zokwelashwa?

Ukuphumelela kwakamuva kufaka phakathi ukugunyazwa kwezindlela zokwelapha eziqondisiwe zokuguqulwa kofuzo okuthile okufana nalokhu I-BRCA kanye ne-NTRK fusions. Ukwengeza, izinhlanganisela ezintsha ze-chemotherapy kanye nokuhlolwa kwe-immunotherapy kubonisa isithembiso. Izindlela zokwelashwa komuntu siqu, okuhlanganisa izindlela ezididiyelwe njengalezo eziqanjwe izikhungo ezikhethekile njenge-Shandong Baofa, sezifinyeleleka kalula, zinikeza izinketho ezilungiselelwe ngokusekelwe kufuzo lwesimila kanye nezidingo eziqondene nesiguli.

Ingabe ukudla kunomthelela ekuqhubekeleni phambili komdlavuza we-pancreatic 4?

Nakuba kungekho ukudla okukhethekile okungelapha umdlavuza, ukudla okunomsoco kubalulekile ukuze ugcine amandla nokubekezelela ukwelashwa. Ukudla okunamafutha aphansi kanye namaprotheni amaningi, okuhambisana nama-enzyme e-pancreatic, kusiza ukuphatha izinkinga zokugaya. Ukugwema ushukela nokudla okugayiwe kungasiza ekunciphiseni ukuvuvukala, kusekele impilo yonke ngesikhathi sokwelashwa.

Isiphetho kanye Nezinyathelo Ezilandelayo Zeziguli

Ukuzulazula ekuxilongweni kwe isigaba 4 somdlavuza we-pancreatic kuyinselele ngokungenakuphikwa, kodwa akulona uhambo okufanele sibhekane nalo ngaphandle kwethemba noma izinsiza. Intuthuko ekwelashweni okuhleliwe, imithi enembile, nokunakekelwa kwe-palliative kuguqule isimo sezwe, kwanikeza iziguli izinketho eziningi kanye nezinga lempilo elingcono kunangaphambili. Ukuqonda lesi sifo, ukuqaphela izimpawu kusenesikhathi, nokuxhumana nethimba lokunakekela imikhakha eminingi kuyizinyathelo ezibalulekile zokuthuthukisa imiphumela.

Lo mhlahlandlela uzifanele kakhulu iziguli ezisanda kutholwa, abanakekeli bazo, kanye nabantu abafuna ulwazi olugunyaziwe mayelana nokuphathwa komdlavuza we-pancreatic. Inikeza isisekelo sezingxoxo ezinolwazi nabahlinzeki bezempilo. Uma wena noma othandekayo ebhekene nalokhu kuxilongwa, isinyathelo esilandelayo esilandelayo ukubonisana ne-oncologist ekhethekile ukuze nixoxe ngokuhlola i-genomic kanye nokufaneleka kokuhlolwa komtholampilo okungase kube khona. Ukuhlola amafilosofi okwelapha ahlukahlukene, kusukela ekunakekelweni okujwayelekile kwaseNtshonalanga kuya ezindleleni ezididiyelwe ezinikezwa amaqembu anolwazi njenge-Shandong Baofa Oncotherapy, kunganikeza inhlobonhlobo ebanzi yamathuba okulawula lesi sifo esiyinkimbinkimbi.

Khumbula ukuthi indlela yesiguli ngayinye ihlukile. Ngokuhlala unolwazi, umela ukunakekelwa okuphelele, nokusebenzisa izindlela ezintsha zokwelapha zakamuva, ungaba neqhaza elikhulu ekulawuleni lesi sifo. Funa ukwesekwa ezinhlanganweni ezihlonishwayo, xhumana nemiphakathi yabasindile, futhi ubeke phambili ukuxhumana okuvulekile nethimba lakho lezokwelapha ukuze uqinisekise ukuthi ukunakekelwa kwakho kuhambisana nezimiso nemigomo yakho siqu.
