Abstract

Abstract: Although some common therapies for cancers are available, many patients experience relapse during therapy. Therefore, an understanding of the pathogenesis of lung adenocarcinomas is needed in lung cancer therapies, especially targeted therapies. Immunotherapy has been shown to be effective in the therapy of various tumors, including non-small cell lung cancer (NSCLC). This study was aimed to review the morphology, pathogenesis, and immunotherapy of lung adenocarcinomas. This was a literature review study using databases of Clinical Key, Pubmed, and Google Scholar. The results showed that morphology of lung adenocarcinomas was characterized by the presence of lesions consisting of several morphological spectra, starting with pre-invasive lesions, then minimally invasive adenocarcinomas to invasive adenocarcinomas. Pathogenesis of lung adenocarcinomas was associated with genetic changes of several genes such as EGFR, KRAS, ALK, and ROS1; however, the most frequently involved were EGFR, KRAS, and ALK. The immunotherapies used for lung adeno-carcinomas were nivolumab, pembrolizumab, atezolizumab, tremelimumab, durvalumab, avelumab, cemiplimab, cetuximab, panitumumab, and matuzumab; however, the most commonly used were nivolumab, pembrolizumab, and atezolizumab. In conclusion, morphological spectra of lung adeno-carcinomas are pre-invasive lesions, minimally invasive adenocarcinomas, and invasive adeno-carcinomas. Pathogenesis of lung adenocarcinomas is associated with the presence of genetic changes, especially mutations of EGFR, KRAS and ALK. The most widely used immunotherapies for lung adenocarcinomas are nivolumab and pembrolizumab, which are included in the PD-1 antibody group and atezolizumab in the PD-L1 antibody group.Keywords: lung adenocarcinoma morphology; pathogenesis; immunotherapy  Abstrak: Telah tersedia beberapa terapi umum kanker namun banyak pasien mengalami kekambuhan saat terapi. Oleh karena itu dibutuhkan pemahaman tentang patogenesis adenokarsinoma paru dalam terapi kanker paru khususnya terapi target. Imunoterapi dianggap sebagai teknologi yang memberikan harapan dan telah terbukti efektif dalam terapi berbagai tumor, termasuk non-small cell lung cancer (NSCLC). Penelitian ini bertujuan untuk menelaah morfologi, patogenesis, dan imunoterapi dari kanker paru tipe adenokarsinoma. Jenis penelitian ialah literature review menggunakan database Clinical Key, Pubmed, dan Google Scholar. Hasil penelitian mendapatkan morfologi adenokarsinoma paru ditandai adanya lesi yang terdiri dari beberapa spektrum morfologik, diawali dengan lesi preinvasif, selanjutnya lesi adenokarsinoma invasif minimal sampai adenokarsinoma invasif. Patogenesis adenokarsinoma paru berhubungan dengan perubahan genetik beberapa gen, yaitu EGFR, KRAS, ALK, dan ROS1; namun yang paling sering terlibat ialah EGFR, KRAS, dan ALK Imunoterapi yang digunakan untuk terapi adenokarsinoma paru ialah nivolumab, pembrolizumab, atezolizumab, tremelimumab, durvalumab, avelumab, cemiplimab, cetuximab, panitumumab, dan matuzumab; namun terbanyak digunakan ialah nivolumab, pembrolizumab, dan atezolizumab. Simpulan penelitian ini ialah spektrum morfologi dari adenokarsinoma paru berupa lesi preinvasif, adenokarsinoma invasif minimal, dan adenokarsinoma invasif. Patogenesis dari adenokarsinoma paru berhubungan dengan adanya perubahan genetik, terutama mutasi EGFR, KRAS, dan ALK. Imunoterapi yang paling banyak digunakan untuk terapi adenokarsinoma paru ialah nivolumab dan pembrolizumab yang termasuk dalam golongan antibodi PD-1 serta atezolizumab yang masuk dalam golongan antibodi PD-L1.Kata kunci: morfologi adenokarsinoma paru; patogenesis; imunoterapi

Abstract

Abstract: The incidence and mortality rates of cervical cancer in developing countries are relatively high compared to developed countries. The main risk factor for cervical cancer is high risk human papilloma virus (HPV) infection, such as types 16 and 18. Types of high-risk HPV expresses oncoproteins E6 and E7 which play an essential role in the pathogenesis of cervical carcinoma through inhibition of the activity of gene group expression products that play a role in suppressing tumor growth, such as p53 and pRB. This process will cause morphological changes in the squamous epithelium from precancerous lesions to cancer. The development of squamous epithelial cell cancer can be prevented through screening tests in order to detect cervical cancer early. This study was aimed to obtain the oncogenesis, morphology, and early detection modality of cervical carcinoma. This was a literature review study using three databases, as follows: ClinicalKey, PubMed, and Google Scholar. The results explained that p53 and pRB suppression by high-risk HPV oncoproteins E6 and E7 played an important role in the pathogenesis of cervical carcinoma. The most common histological type is squamous cell carcinoma. Screening tests such as visual inspection with acetic acid (VIA), Pap smears and HPV DNA have an important role as modalities for early detection of malignancy. More specifically VIA and Pap smears are suitable for Indonesia which is a developing country, especially when implemented in peripheral areas.Keywords: oncogenesis; morphological changes; early detection; cervical carcinoma  Abstrak: Insidens dan mortalitas kanker serviks di negara berkembang relatif tinggi dibandingkan negara maju. Faktor risiko utama dari kanker serviks adalah infeksi human papilloma virus (HPV) risiko tinggi yaitu tipe 16 dan 18. HPV tipe risiko tinggi mengekspresikan onkoprotein E6 dan E7, yang berperan penting dalam patogenesis karsinoma serviks melalui inhibisi terhadap aktivitas produk-produk ekspresi kelompok gen yang berperan dalam menekan pertumbuhan tumor, seperti p53 dan pRB. Proses ini akan menyebabkan perubahan morfologik pada epitel skuamosa mulai dari lesi prakanker sampai kanker. Perkembangan kanker sel epitel skuamosa dapat dicegah melalui pemeriksaan skrining guna mendeteksi dini kanker serviks. Penelitian ini bertujuan untuk mengetahui onkogenesis, morfologi, dan modalitas deteksi dini karsinoma serviks. Jenis penelitian ialah literature review menggunakan tiga basis data yaitu ClinicalKey, PubMed, dan Google Scholar. Hasil penelitian mendapatkan bahwa penekanan p53 dan pRB oleh onkoprotein HPV risiko tinggi E6 dan E7 sangat berperan penting dalam patogenesis karsinoma serviks. Tipe histologik tersering ialah tipe karsinoma sel skuamosa. Pemeriksaan skrining seperti pemeriksaan inspeksi visual dengan asam asetat (IVA), Pap smear dan HPV DNA memiliki peran penting sebagai modalitas deteksi dini keganasan. Lebih khusus IVA dan Pap smear cocok untuk negara Indonesia yang merupakan negara berkembang, terutama bila diimplementasikan di daerah perifer.Kata kunci: onkogenesis; perubahan morfologik; deteksi dini; karsinoma serviks
