Oxirgi yillarda me'da saratonining uchrash darajasi kamayganligiga qaramasdan ushbu kasallik hamon o'zining yuqori ahamiyatini saqlab qolmoq da. Hozirda me'da saratoni uchrashi bo'yicha umumiy saraton kasalliklarining 8%ni, o'lim ko'rsatkichi boyicha 10%ni tashkil etadi. Kasallik ko'proq erkaklarda kuzatilib, Osiyo mintaqasida uchrash chastotasi eng yuqori ko'rsatkichga ega. MSning yosh bo'yicha uchrashi o'rtacha 69 yoshni tashkil etib, 75-84 yosh oralig'ida eng yuqori ko'rsatkichga ega bo'ladi. MS tashhisi qo'yilgan barcha bosqichdagi bemorlar uchun 5 yillik umr ko'rsatkichi 27,7%ni tashkil etadi. Shuni qayd etish kerakki, oxirgi yillar davomida MS bilan kasallanish ko'rsatkichi kamaydi. Biroq, tashxislash va davolashdagi yutuqlarga qaramasdan MSning kechki bosqichlarida 5 yillik umr ko'rsatkichi yomonligicha (3,7%) qolmoqda. Me'dada uchrovchi barcha yomon sifatli o'sma kasalliklarining asosiy ulushi me'da adenokarsinomasiga ( > 95%) to'g'ri keladi. Kam uchrovchi turlari sarasiga esa mezenhimal, limfaproliferativ va neyroendokrin neoplazmlar kiradi. Oxirgi besh dekadada kasallik uchrashi kamaygandek bo'lsada hozirda ham ko'plab dunyo mamlakatlari ushbu kasallikdan aziyat chekmoqda (1). Hozirgi kunda endoskopiya, xirurgiya va ummumiy davo usullari hamda kasallikka multiditsiplionar yondashuv imkoni bolganiga qaramasdan hamon MAKli bemorlar 5 yillik o'rtacha yashovchanligi qoniqarsizligicha ( 25-30%)

qolmoqda. Kasallikning erta tashhislanishi ( TNM klassifikatsiyasi bo'yicha T1 bosqichda) va to'g'ri va samarali davo taktikasini tanlanishi yuqoridagi ko'rsatgichlarni yaxshilashga olib kelishi shubhasiz.
MATERIAL VA METODLAR
Tadqiqot uchun "Akfa Medlayn" klinikasi sharoitida birinchi qator kimyoviy davoni standart bo'yicha qabul qilgan 39 nafar Her 2neu manfiy metastatik me'da adenokarsinomali bemorlar tanlab olindi. Bemorlarning 20 nafarida (51.3%) paraaortal limfa tugunlarining zararlanishi, hamda 8 nafar (20.6%) bemorda o'smaning qo'shni a'zo va qon tomirlarga o'sib o'tishi aniqlangan, shu sababli ushbu holatlar norezektabel kasallik sifatida baholangan. Bemorlarning 11 nafarida esa (28.2%) distant metastazlar aniqlangan (jigar, qorin parda va tana skelet suyaklari). Bemorlar birinchi qator standart davo sifatida 5-FU va platina unumli dori vositalarini qabul qilgan. Ularning 20 nafari ikkinchi qator kimyoviy davo sifatida ramicirumab va irinotekan hamda 19 nafari irinotekan va platsebo qabul qilgan.
Davolashning olib borilishi - bemorlar ramucirumab va irinotekan yoki platsebo va irinotekan oluvchi guruhlarda 1:1 nisbatda randomizatsiyalangan. Ramucirumab (8 mg/kg) 1 va 15-kunlarda vena ichiga infuziya ko'rinishida yoki davolanishning 1-21 kunlarida irinotekan 350 mg/m2 bilan birgalikda infuziya ko'rinishida yuboriladi. Bemorlar kasallikning progressiyasi, nojo'ya ta'sirlarining ortib ketganligida yoki bemorlarning davodan o'zlari bosh tortmagunicha davom ettirildi.
NATIJA VA UNI BAHOLASH
O'simtani baholash dastavval va har 6 haftada bir marta kasallikning rivojlanishiga qadar o'tkazildi. Kaplan-Meier usuli KHY (kasallikdan holi yashovchanlik) va UY (umumiy yashovchanlik) uchun yashovchanlik egri chizig'ini yaratishda ishlatilgan. O'rtacha KHY va UY tegishli 95% CI (ishonchlilik indeksi) Kaplan-Meier usuli yordamida baholandi. Davolanish samarasining xavf darajasi (HR) tabaqalanmagan Cox PH modeli yordamida, p-qiymati esa tabaqalanmagan log-darajali test yordamida hisoblangan. Kasallikni bosqichlashda Milliy Saraton Institutining me'da saratoni uchun umumiy terminologiya mezonlariga (NCI-CTCAE; versiya 4.02) muvofiq olingan. Atamalarning qisqartmalari matin ichida keltirilgan.

Ramicirumab va irinotekan qabul qilgan bemorlarning umumiy yashovchanligi (11.4 oy; 95% CI: 7.0-17.9), irinotekan va platsebo guruhidagi bemorlarnikiga nisbatan (7.0 oy; 95% CI: 3.4-14.6) yuqori ekanligi aniqlangan (HR-0.68 (0.33-1.41) p=0.30). Yuqori kasallikdan holi yashovchanlik ko'rsatgichi ham aynan ramiciruman kambinatsiyalangan guruh hisobiga to'g'ri kelgan.
Davoning nojo'ya ta'sirlari - ramucirumab va irinotekan hamda platsebo va irinotekan kombinatsiyasini qabul qilgan bemorlarda har qanday darajadagi kamida bitta nojo'ya ta'sir kuzatilgan. Ikkala guruhdagi har qanday darajadagi keng tarqalgan nojo'ya ta'sirlar sifatida quyidagilarni keltirish mumkin: burundan qon ketish, neytropeniya, alopetsiya, charchoq, ishtahaning pasayishi, leykopeniya, ko'ngil aynishi, ich qotishi, gipertenziya, periferik sensorli neyropatiya, qusish, anemiya, yo'tal, periferik neyropatiya, periferik shish va pireksiya. Ramucirumab va irinotekan guruhi irinotekan va platsebo guruhiga nisbatan (nojo'ya ta'sir darajasi >3) yuqori neytropeniya (45,0% ga nisbatan 15,8%), leykopeniya (20,0% ga qarshi 0,0%), anemiya (10,0% ga nisbatan 0,0%) va periferik sensorli neyropatiya (10,0% va 5,35%) teng bo'lgan mos ravishda.

TADQIQOT TAHLILI
Me'da saratonidagi so'nggi terapevtik yutuqlar asosan VEGFR-2 va HER-2 [8,15] ga qaratilgan. HER-2-musbat ko'krak bezi saratoniga asoslangan mavjud klinik ma'lumotlar HER-2 ning ortiqcha ishlab chiqarilishi va o'sma angiogenezining faollashishi o'rtasidagi bog'liqlikni ko'rsatadi. O'sma hujayralarida HER-2 ning haddan tashqari ko'payishi VEGF tasiri doirasi va angiogenezning faollanishiga sabab bo'ladi va ushbu hususiyat tufayli o'smaning omon qolishi mexanizmlari (surveillance) yuzaga keladi va faollashadi [13,16]. Ramucirumab monoklonal antitana - VEGFR-2 antagonisti hisoblanadi, ligandlarning bog'lanishiga va endotelial hujayralardagi retseptorlar faollashishiga to'sqinlik qiladi [17]. Trastuzumab qarshiligini VEGFR-2 ingibitorlari, masalan, ramucirumab kabi angiogenez

ingibitorlari orqali bartaraf etish mumkin. So'ngi nashr etilgan tadqiqot natijalariga ko'ra HER2-musbat metastatik me'da saratoni bilan og'rigan bemorlarda trastuzumabni davom ettirish klinik samaradorlikka ega [18]. Biroq, prospektiv va retrospektiv tadqiqotlar birinchi qatorli trastuzumab va kimyoterapiya kombinatsiyasida kasallik progressiyasi yuzaga kelgan bemorlarda ikkinchi qator sifatida trastuzumab kombinatsiyalaridan foydalanish UY va KHY kabi muhim prognostik omillardagi sezilarli farqni yo'q ekanligini ko'rsatadi [9,15,18]. Birinchi qator sifatida 5-FU va platina unumi olgan bemorlarning tadqiqot qilinganida, platsebo va irinotekan guruhi (7,0 oy; 95% CI: 3.4-14.6) ikkinchi qator ramusirumab va irinotekan kombinatsiyasi bilan solishtirganda yuqori o'rtacha UY (11,4 oy; 95% CI: 7,0-17,9) erishilganligini kuzatishimiz mumkin. Ramucirumab va irinotekan guruhida KHY platsebo va irinotekan guruhiga nisbatan uzun ekanligini ko'rishingiz mumkin. Hozirgi vaqtda ramucirumab uchun davo samarasini boholaydigan aniq biomarkerlar mavjud emas, shuning uchun davolanishdayuqori samaradorlikka erishadigan bemorlarni tanlash qiyin. VEGF yo'li bilan bog'liq bo'lgan asoratlar alohida qiziqish uyg'otdi: qon ketish hodisalari, gipertenziya, oshqozon-ichakdan qon ketishi va proteinuriya. Ushbu kichik guruh tahlilining cheklovlari kichik namuna hajmi va bu retrospektiv tahlil bo'lib, etarlicha quvvatga ega emas edi. Davolanish vositalarining samaradorligi va xavfsizligi bo'yicha kuzatilgan raqamli farqni statistik jihatdan ahamiyatli deb hisoblash mumkin emas va bemorlar trastuzumab bilan oldingi terapiyaning kichik guruhida randomizatsiyalanmaganligi bilan izohlashda qo'shimcha qiyinchilik tug'diradi. Bizning kichik guruh tahlilimiz, namuna hajmi bilan cheklangan bo'lsa-da, ramucirumabga asoslangan terapiyaning raqamli klinik afzalliklarini aniqladi. Oldindan trastuzumab olmagan bemorlarda ramucirumab asosidagi kombinatsiyalangan terapiyaning klinik afzalliklarini tasdiqlash uchun istiqbolli klinik tadkikotlarda qo'shimcha tadqiqotlar o'tkazish talab etiladi.
XULOSA
So'nggi sinovlar shuni ko'rsatdiki, HER+ manfiy bo'lgan metastatik me'da saratonida birinchi va ikkinchi qator davoni tanlashda yetarlicha samarali vositalar mavjud emas (trastuzumab). Ushbu kichik guruh tahlili natijalari shuni ko'rsatadiki, ramucirumab irinotekan bilan birgalikda HER+ manfiy bo'lgan metastatik me'da adenoikarsinomali bemorlarda davolashning boshqariladigan asoratlarining kamligi bilan samarali. Ramucirumabning irinotekan bilan birgalikda qo'llanilishi birinchi

qator terapiyadan qat'i nazar, bemorlar uchun standart tibbiy yordam bo'lib qolmoqda.
