Terapi kanker payudara stadium 0 (noninvasif)

http://www.cancer.org/Cancer/BreastCancer/DetailedGuide/breast-cancer-treating-stage0

Terapi kanker payudara stadium 0 (noninvasif) Kanker payudara non-invasif jenis lobular carcinoma in situ (LCIS) dan ductal carcinoma in situ (DCIS) sangat berbeda. LCIS: Karena jenis ini bukan kanker yang sebenarnya, tidak ada terapi segera atau aktif yang disarankan untuk wanita dengan LCIS. Namun karena LCIS mningkatkan resiko perkembangan kanker invasif di kemudian hari, mengikuti perjalanan penyakit/ follow-up sangatlan penting. Dalam hal ini mammogram tahunan dan uji klinis payudara perlu dilakukan. Follow-up untuk kedua payudara perlu dilakukan karena biasanya jika terdapat LCIS pada satu payudara maka resiko terjadi kanker sama meningkatknya untuk kedua sisi payudara. Walaupun tidak ada bukti yang cukup untuk menyarankan MRI rutin sebagai tambahan mammogram untuk wanita dengan LCIS, sebaiknya dianjurkan untuk berkonsultasi dengan klinisi mengenai manfaat dan keterbatasan MRI tahunan sebagai tindakan skrining. Wanita dengan LCIS biasanya ingin mempertimbangkan penggunaan tamoksifen atau raloksifen untuk menurunkan resiko kanker payudara, atau berpartisipasi dalam uji klinis pencegahan kanker payudara. Atau, mereka ingin mendiskusikan juga mengenai strategi pencegahan yang dapat dilakukan (mencapai bobot badan optimal atau melakukan olahraga) dengan klinisinya. Beberapa wanita dengan LCIS memilih untuk mastektomi bilateral sederhana (menghilangkan kedua sisi payudara tetapi bukan nodus limfe axillaris) untuk mengurangi resiko kanker payudara, terutama jika mereka mempunyai faktor resiko lain, misalnya riwayat keluarga. Tergantung pilihan wanita ini, dia mungkin ingin segera melakukan atau menunda rekonstruksi payudara. DCIS: Pada kebanyakan kasus, wanita dengan DCIS dapat memilih antara terapi mempertahankan payudara (lumpectomy, biasanya diikiti dengan terapi radiasi) dan mastektomi sederhana. Menghilangkan nodus limfe (sering kali biopsi nodus linfe sentinel) tidak diperlkan, tapi dapat dilakukan jika doktor menganggap DCIS memngandung area kanker invasif. Resiko bahwa DCIS mengandung area kanker invasif makin besar seiring dengan ukuran tumor dan derajat inti. Banyak doktor melakukan biopsi nodus limfe sentinel jika dilakukan mastektomi. Terapi radiasi setelah lumpektomi menurunkan kemungkinan kanker kembali pada payudara yang sama (baik sebagai DCIsi atau sebagai kanker invasif). Lumpektomi tanpa radiasi bukan merupakan terapi standard, tetapi merupakan pilihan bagi wanita dengan DCIS derajat rendah atau area yang kecil yang telah dihilangkan bersama dengan batasan jaringan bebas kanker yang luas. Namun kebanyakan wanita yang mendapat tindakan lumpektomi untuk DCISnya akan memerlukan terapi radiasi. Mastektomi mungkin iperlukan jika area DCIS sangat luas, jika payudara menunjukkan beberapa area DCIS, atau jika lumpektomi tidak dapat menghilangkan seluruh DCIS secara sempurna (spesimen lumpektomi dan spesimen pengirisan ulang menunjukkan sel kanker dalam atau di dekat tepian bedah). Wanita yang mastektomi untuk DCIsnya juga dapat mendapat tindakan rekonstruksi payudara segera atau kemudian.

Jika DCISnya bersifat positif untuk reseptor-estrogen ( estrogen receptor-positive), terapi tamoksifen selama 5 tahun setelah tindakan bedah dapat menurunkan resiko timbulnya DCIS atau kanker invasif di payudara sisi lainnya. Last Revised: 06/11/2012

Terapi kanker payudara invasif, berdasarkan stadium Tindakan bedah untuk mempertahankan payudara biasanya cocok untuk kanker invasif stadium dini jika ukuran kanker relatif kecil, walaupun mastektomi juga merupakan salah satu pilihan tindakan lain. Jika kanker terlalu besar, diperlukan tindakan mastektomi kecuali jika kemoterapi neoajuvan sebelum tindakan bedah dapat mengecilkan ukuran tumor sehingga cukup dilakukan tidakan radiasi yang mempertahankan payudara. Pada kasus manapun , nodus limfe di bawah lengan/ketiak harus dicek apakah mengandung kanker. Radiasi diperlukan untuk hampir semua pasien yang mendapat tindakan bedah yang mempertahankan payudara dan pada beberapa pasien yang mendapat tindakan masetektomi. Terapi sistemik ajuvan setelah tindakan bedah bisanya disarankan untuk semua kanker yang berukuran lebih besar dari 1 cm, juga kadang-kadang pada tumor yang lebih kecil.

Stadium I Kanker ini relatif kecil dan mungkin belum menyebar ke nodus limfe (N0) atau ada penyebaran sedikit ke nodus limfe sentinel (N1mi). Terapi lokal: Kanker stadium I dapat diatasi dengan tindakan bedah yang mempertahankan payudara (lumpectomy, partial mastectomy) atau mastektomi. Nodus limfe juga harus dievaluasi, dengan biopsi nodud limfe sentinel atau dengan pengambilan (dissection) nodus limfe axilla. Rekonstrukdi payudara dapat dilakukan saat itu juga bersamaan dengan tindakan bedah atau beberapa waktu kemudian. Terapi radiasi biasanya diberikan setelah tindakan bedah yang mempertahankan payudara. Pasien dapat mempertimbangkan tindakan bedah yang mempertahankan payudar tanpa radiasi jika semua hal berikut benar:  Usia lebih dari atau sama dengan 70 tahun.  Ukuran tumor kurang dari atau sama dengan 2 cm dan telah benar-benar diambil

seluruhnya.  Tumor mengandung reseptor hormon dan diberi terapi hormon.  Tidak satupun nodus limfe yang telah diambil mengandung kanker.

Beberapa pasien yang tidak memenuhi kriteria tersebut mungkin dapat mencoba menghindari radiasi, tetapi studi-studi menunjukkan pasien yang tidak mendapat radiasi memiliki kemungkinan kankernya kembali muncul. Terapi ajuvan sistemik: Kebanyakan klinisi akan mendiskusikan pro dan kontra terapi ajuvan hormonal (tamoksifen, inhobitor aromatase, atau keduanya berurutan) dengan semua pasien yang kankernya positive reseptor hormon (hormone receptor–positive (estrogen atau progesterone)),

2

seberapapun ukuran tumornya. Manfaat terapi hormonal biasanya lebih mungkin dialami oleh pasien dengan ukuran tumor lebih besar dari 0,5 cm. Jika tumor lebih kecil dari 1 cm, kemoterapi ajuvan biasanya tidak diberikan. Beberapa klinisi mungkin menyarankan kemoterapi jika kanker kurang dari 1 cm disetai beberapa karakteristik kurang baik (misalnya derajat-tinggi, hormone receptor–negative, HER2-positive, atau skor yang tinggi pada salah satu panel gen). Khemo ajuvan biasanya disarankan untuk kanker yang berukuran lebih besar. Untuk kanker yang HER2-positive, ajuvan trastuzumab (Herceptin) biasanya disarankan juga.

Stadium II Kanker ini biasanya lebih besar dan/atau menyebar ke sekitar nodus limfe. Terapi lokal: Tindakan bedah dan radiasi sama seperti pada tumor stadium I, kecuali pada stadium II, terapi radiasi ke dada dapat dipertimbangkan bahkan setelah mastektomi jika tumor berukuran besar (lebih dari 5 cm) atau sel kanker ditemukan I nodus limfe. Terapi ajuvan sistemik: Terapi ajuvan sistemik disarankan untuk pasien dengan kanker stadium II. Terapi yang diberikan mungkin melibatkan terapi hormon, kemoterapi, trastuzumab, atau kombinasi pilihan tersebut, dan tergantung pada usia pasien, status reseptor-estrogen, dan status Her2/neu. Terapi neoajuvan: Salah satu pilihan bagi pasien yang menginginkan mempertahankan payudara, tetapi ahli bedah menganggap tumor terlalu besar sehingga outcome kurang baik, adalah terapi neoajuvan (sebelum tindakan bedah) dengan kemoterapi, terapi hormon, dan/atau trastuzumab untuk mengecilkan tumor. Jika terapi neoajuvan berhasil mengecilkan tumor, pasien dapat memilih tindakan bedah yang mempertahankan payudara (misalnya lumpektomi) diikuti dengan tindakan radiasi. Terapi ajuvan juga dapat diberikan setelah radiasi. Jika tumor tidak cukup mengecil, maka diperlukan mastektomi. Terapi ajuvan juga dapat diberikan setelah tindakan bedah, karena tumor tidak mengecil ketika diberikan neoajuvan. Terapi radiasi juga dapat diberikan setelah tindakan bedah. Kemungkinan survival pasien dari kanker payudara tidak dipengaruhi oleh apakah pasien mendapat kemoterapi sebelum atau setelah tindakan bedah.

Stadium III Kanker stadium III adalah jika tumor lebih besar dari 5 cm atau berkembang ke dalam jaringan lain di sekitarnya (kulit di atas payudara atau jaringan otot di bawahnya), atau kanker menyebar ke nodus limfe di sekitarnya. Terapi lokal untuk beberapa kanker stadium III kuranglebih sama dengan stadium II. Tumor yang relatif kecil (dan belum berkembang ke jaringan sekitarnya) dapat dihilangkan dengan tindakn bedah yang mempertahankan payudara (lumpektomi) diikutitindakan radiasi. Jika tidak demikian, maka dilakukan tindakan mastektomi (baik dengan atau tanpa rekonstrukdi payudara). Biopsi nodus limfe sentinel dapat menjadi pilhan pasien, namun kebanyakan memerlukan pemeriksaan nodus limfe axilla. Tindakan bedah biasanya

diikuti dengan kemoterapi ajuvan sistemik, dan/atau terapi hormon, dan/atau trastuzumab. Radiasi setelah mastektomi juga sering disarankan. Seringkali, kanker stadium III ditangani dengan kemoterapi neoajuvan. Tindakan ini mungkin akan mengecilkan tumor adekuat sehingga dapat dilakukan lumpektomi atau tindakan bedah yang mempertahankan payudara. Jika tidak, maka harus dilakukan mastektomi. Biasanya juga dilakukan pemeriksaan nodus limfe axilla. Rekonstruksi segera mungkin merupakan pilihan bagi beberapa pasien, namun biasanya ditunda sampai setelah terapi radiasi, yang diberikan juga bahkan untuk mastektomi. Kemoterapi ajuvan juga dapat diberikan, dan terapi hormonal ditawarkan pada semua pasien yang kankernya hormone receptor–positive. Beberapa kanker payudara inflamasi termasuk stadium III. Bisanya diterapi dengan kemoterapi neoajuvan, kadang-kadang dengan radiasi. Kemudian diikuti dengan mastektomi dan pemeriksaan nodus limfe. Kemudian diberikan terapi ajuvan dengan kemoterapi (dan trastuzumab jika kanker HER2+), terap radiasi (jika tidak diberikan sebelum tindakan bedah), dan terapi hormon (jika kanker hormone receptor positive).

Obat-obat terapi ajuvan untuk kanker stadium I sampai III Terapi ajuvan dapat disarankan, berdasarkan ukuran tumor, penyebaran ke nodus limfe, dan parameter prognosis lainnya. Biasanya dapat berupa kemoterapi, trastuzumab (Herceptin), hormon, atau kombinasi obat-obat tersebut. Terapi hormon: Terapi hormon kemungkinan tidak efektif untuk pasien dengan tumor hormone receptor-negative. Terapi hormon seringkali ditawarkan untuk pasien dengan kanker payudara invasif yang hormone receptor–positive berapapun ukuran tumor maupun nodus limfe yang terlibat. Pasien yang belum menopause dan tumornya hormone receptor–positive dapat diteapi dengan tamoxifen, yang menghambat efek estrogen yang diproduksi ovarium. Beberapa klinisi juga memberikan analog luteinizing hormone-releasing hormone (LHRH)yang akan menghentikan ofungsi ovarium sementara.Pilihan (permanen) lain adalah pengambilan ovarium melalui tindakan bedah (oophorectomy). Namun, belum jelas apakah pengambilan ovarium atau mengehntikan kerjanya akan membantu kerja tamoksfe. Jika pasien mengalami menopause dalam 5 tahun sejak menggunakan tamoksifen (baik secara alami maupun karena ovariumnya diangkat), pasien dapat mengganti tamoksifen dengan obat lain inhibitor aromatase. Terkadang pasien dapat ,engalami berhentinya menstruasi setealh kemoterapi atau ketika diterapi tamoksifen. Namun tidak berarti pasien ini mengalami menopause. Klinisi dapat melakukan uji darah untuk mengetahui keadaan beberapa hormon untuk mengetahui status menopausenya. Hal ini penting karena obat inhibitor aromatase hanya bermanfaat untuk pasien setelah menopause. Pasien yang tidak lagi menstruasi, atau yang memang telah menopause berapaun usianya, dan pasien yang tumornya hormone receptor–positive biasanya akan mendapat terapi ajuvan baik dengan inhbitor aromatase (biasanya selama 5 tahun), atau dengan tamoksifen selama 2-5 tahun diikuti dengan inhibitor aromatase selama 3-5 tahun lagi. Pasien yang tidak dapat mengkonsumsi inhibior aromatase dapat menggunakan tamoksifen sebagai alternatif selama 5 tahun. Seperti telah disampaikan sebelumnya, masih banyak yang belum bisa dijawab bagaiman cara menggunakan obat-obat ini yang sebaik-baiknya. Sebagai contoh, masih belum jelas apakah memberikan terapi ajuvan dengan salah satu obat tersebut lebih baik daripada dengan pemberian 4

tamoksifen elama beberpa waktu kemudian dilanjutkan inhibitor aromatase. Atau berapa lama waktu penggunaan inhibitor aromatase yang optimal. Banyak studi yang sedang dilakukan untuk menjawab pertanyaan-pertanyaan demikian. Jika kemoterapi juga harus diberikan, terapi hormon biasanya diberikan jika kemoterapi telah sempurna selesai. Kemoterapi: Keoteapi biasanya disarankan untuk semua pasien dengan kanker payudara invasif yang bersifat hormone receptor-negative, dan bagi pasien dengan tumor hormone receptorpositive yang mungkin akan mendapat manfaat tambahan dengan pemnggunaan kmoterapi bersama terapi hormon, berdasarkan stadium dan karakteristik tumornya. Kemoterapi ajuvan dapat menurunkan resiko kanker kembali/kambuh, tetapi tidak menghilangkan resiko sama sekali. Sebelum memutuskan apakah pengobatan tepat, penting untuk megetahu seberapa resiko kanker kambuh dan seberapa jauh terapi ajuvan dapat mengurangi resiko tersebut. Regimen kemoterapi dapat dilihat pada daftar, biasanya berkisar antara 4-6 bulan. Pada beberapa kasus mungkin diperlukan kemoterapi dengan interval dosis yang lebih rapat (dose-dense). Trastuzumab (Herceptin): Pasien yang kankernya HER2-positive biasanya mendapat trastuzumab bersama dengan kemoterapi. Salah satu regimen yag umum adalah doxorubicin (Adriamycin) dan cyclophosphamide selama 3 bulan, diikuti dengan paclitaxel (Taxol) dan trastuzumab. Paclitaxel diberikan selama 3 bulan, sedangkan trastuzumab diberikan total selama 1 tahun. Salah satu kekhawatiran klinisi adalah jika trastuzumab diberikan terlalu cepat setealh pemberian doxorubicin dapat mengakibatkan masalah pada jantung, sehingga fungsi jantung harus dimonitor dengan ketat selama terapi antara lain dengan echocardiograms atau pencitraan MUGA. Untuk mengurangi efek samping pada jantung, klinisi juga mencoba kombinasi terapi yang tidak mengandung doxorubicin. Salah satu regimen demikian adalah TCH, yaitu docetaxel (Taxotere) dan carboplatin setiap 3 minggu bersama dengan trastuzumab (Herceptin) selama 6 siklus. Kemudian diikuti dengan trastuzumab setiap 3 minggu selama 1 tahun. Uji pola gene (gene pattern test): Beberapa klinisi mungkin menggunakan uji/pemeriksaan pola gen untuk membantu menentukan apakah perlu terapi ajuvan pada kanker payudara stadium I dan II. Contoh uji demikian antara lain Oncotype DX dan MammaPrint, yang dijelaskan lebih detil pada bagian bagaimana kanker payudara didiagnosis "How is breast cancer diagnosed?" Uji demikian dilakukan menggunakan sampel jaringan kanker payudara. Yang dilihat adalah fungsi beberapa gen dalam kanker untuk membantu memperkirakan resiko kambuhnya kenker setealh terapi. Ui ini tidak akan membantu klinisi menetukan terapi hormon atau kemoteapi apa yang terbaik bagi pasien. Uji ini membantu klinisi mengetahui seberapa manfaat terapi ajuvan bagi pasien. Studi klinis besar masih dilakukan untuk mengetahui pakah uji gen demikian dapat membantu klinisi ketika menghadapi pasien dengan tumor kecil dan nodus limfe yang bersih. Alat bantu online untuk membantu mengambil keputusan: Untuk membantu memilih terapi ajuvan apa yang tepat untuk pasien, psien dapat mengunjungi situs Mayo Clinic Web di www.mayoclinic.com dan mengetik "adjuvant therapy for breast cancer" ke kotak pencarian. 5

Lam itu akan membantu psien memahami manfaat yang dapat diharapkan dan apa keterbatasan terapi ajuvan. Pedoman online lain, seperti www.adjuvantonline.com, didesain utnuk digunkan oleh profesional kesehatan. Situs wen tersebut menyediakan infomrasi mengenai resiko kanker akan kambuh dalam 10 tahun ke depan dan manfaat apa yang dapat diharapkan dari terapi hormon dan/atau kemoterapi.

Stadium IV Kanker stadium IV telah menyebar di luar payudara dan nodus limfe ke bagian tubuh lainnya. Kanker payudara bisanya menyebar ke tulang, hati dan paru-paru. Kanker stadium IV juga dapat menyebar ke otak, atau organ lain, termasuk mata. Walaupun tindakan bedah dan/atau radiasi dapat bermanfaat pada situasi tertentu, terapi sistemik masih merupakan terapi yang utama. Tergantung pada banyak faktor, terapi dapat berupa hormonal, kemoterapi, terapi yang ditargetkan (targeted therapy) seperti trastuzumab, pertuzumab (Perjeta), dan lapatinib (Tykerb), atau kombinasi obat-obat tersebut. Terapi dapat mengecilkan tumor, memperbaiki gejala, dan membantu pasien hidup lebih panjang, namun tidak dapat mengusir kanker sepenuhnya dan seterusnya. Trastuzumab dapat membantu psien dengan kanker yang HER2-positive hidup lebih lama jika diberikan bersama dengan kemoterapi pertama untuk kanker stadiumIV. Pemberian pertuzumab dengan kemoteapi dan trastuzumab mungkin lebih baik lagi. Pemberian Trastuzumab juga dapat membantu jika diberikan bersama dengan terapi hormon letrozole. Masih belum jelas berapa lama terapi trastuzumab atau pertuzumab harus dilanjutkan. Semua terapi sistemik untuk kanker payudara— terapi hormon, keoterapi dan terapi yang ditargetkan — mempunyai efek samping. Terapi radiasi dan/atau tindakan bedah juga dapat diberikan pada situasi berikut:       

Ketika tumor payudara mengakibatkan luk terbuka pada payudara (atau dada) Untuk mengatasi sejumlah kecil metasatases pada area tertentu Untuk mencegah patah tulang Ketika are kanker menyebar menekan korda spinalis Untuk mengatasi blokade pada hati Untuk meringankan nyeri tau gejala lain Ketika kanker menyebar ke otak

Terapi lokal demikian harus jelas tujuannya (dijelaskan pada pasien), apakah untuk menyembuhkan kanker, mencegah atau mengatasi gejala. Pada beberapa kasus terapi regional (obat diberikan langsung ke area tertentu, misalnya cairan sekitar otak atau ke dalam hati) dapat juga bermanfaat. Terapi untuk meringankan gejala tergantung pada daerah penyebaran kanker. Sebagai contoh, nyeri akibat metastase tulang dapat diatasi dengan terapi radiasi sinar eksternal dan/atau bifosfonat misalnya pamidronate (Aredia) atau asam zoledronat (zoledronic acid/Zometa). Kebanyakan klinisi menganjurkan bisphosphonates atau denosumab (Xgeva), bersama dengan

6

calcium dan vitamin D, untuk semua pasien yang kanker payudaranya telah menyebar ke tulang (lihat juga informasi pada bab Bone Metastasis.) Kanker stadium lanjut yang terus berkembang selama terapi: Terapi untuk kanker stadium lanjut dapa mengecilkan atau mempelambat pertumbuhan sel-sel kanker (seringkali untuk bertahun-tahun), namun diperkirakan obat akan berhenti bkerja setealh beberapawaktu. Terapi lanjutan pada keadaan ini tergantung pada beberapa faktor, termasuk terapi sebelumnya, lokasi kanker, usia pasien, kesehatan umum, dan keinginan pasien untuk melanjutkna terapi. Untuk kanker yang hormone receptor–positive yang diterapi hormon, menggantinya denga terapi hormon lain mugkin bermanfaat. Jika tidak, maka langkah selanjutnya adalah kemoterapi. Untuk kanker yang tidak lagi merespon regimen kemoterapi tertentu, dapat diganti dengan regimen kemoterapi lainnya. Banyak obat dan kombinasi yang dapat digunakan untuk mengatasi kanker payudara. Namun, setiap kali kanker berlanjut/progresi selama terapi maka terapi berikutnya akan makin kecil kemungkinan berefek. Kanker HER2-positive yang tidak lagi merespon trastuzumab mungkin masih bisa merespon lapatinib. Lapatinib juga menyerang protein HER2. Obat ini bisanya diberikan bersama kemoterapi capecitabine (Xeloda), namun bisa juga bersama kemoterapi lain, bersama trastuzumab, atau bahkan tunggal (tanpa kemoterapi). Karena terapi saat ini kelihatannya tidak menyembuhkan kanker stadium lanjut, pasien dapat dianjurkan untuk berpartisipasi dalam uji clinical trial. Menggunakan terapi lain yang potensial.

Kanker payudara kambuh (rekurensi) Kanker disebut kambuh (recurrent) jika muncul kembali setealh terapi. Rekurensi dapat bersifat lokal (di payudara yang sama atau bekas mastektomi) atau di tempat yang lain. Jarang, kanker payudara muncul kembali di nodus limfe sekitar). Keadaan ini disebut rekurensi regional. Kanker yang ditemukan di payudara yang sebelahnya tidak disebut rekurensi—melainkan termasuk kanker baru yang perlu diterapi tersendiri. Rekurensi lokal: Terapi kanker rekurensi lokal tergantung pada tindakan terapi sebelumnya. Jika pasien sebelumnya mendapat tindakan yang mempertahankan payudara, rekurensi lokal biasanya diatasi dengan mastektomi. Jika terapi sebelumnya adalah mastektomi, rekurensi didaerah sekitar mastektomi jika memungkinkan diatasi dengan tindakan pengambilan untuk menghilangkan sel-sel kankerKemudian diikuti dengan terapi radiasi, hanya jika belum pernah dilakukan setelah tindakan bedah awal. Radiasi tidak bolh diberikan pada daerah yang sama dua kali. Pada kasus manapun, terapi hormon, trastuzumab, kemoterapi, ataukombinasinya dapat digunakan setealh tindakan bedah dan/atau radiasi. Rekurensi regional: Jika kanker kambuh sebagai bentuk penyebaran ke nodus linfe sekitarnya (misalnya di bawah lengan/ketiak atau pada tulang leher), maka diatasi dengan mengambil nodus limfe. Kemudaian diikuti dengan radiasi pada are yang bersangkutan. Terapi sistemik (kemoterapi atau hormon) dapat dipertimbangkan setelah terapi lokal. Rekurensi distant/jauh: Secara umum, pasien yang mengalami rekurensi pada organ-organ tulang, paru-paru, otak, dll, diatasi dengan cara seperti pada stadium IV. Perbedaannya hanya pada respon terapi yang mungkin dipengaruhi oleh terapi sebelumnya yang telah diterima pasien. Lihat juga informasi pada bab lain (When Your Cancer Comes Back: Cancer Recurrence). 7
