"Menurut beberapa peneliti salah satu faktor penyebab timbulnya kanker, adalah terapi dengan betaestradiol dosis tinggi, atau dosis adekuat yang tidak terkontrol. Terapi ini telah digunakan selama 30 tahun terakhir terutama kaitannya dengan menopause prematur, hysterektomi total, salpingo-ooforektomi, kontrasepsi, dll. Namun demikian tidak mudah melakukan penilaian keuntungan yang diperoleh serta efek sampingnya. Terlebih lagi bila pemanfaatan estradiol dilakukan pada penderita kanker payudara. Sehingga perlu dicari dosis yang masih aman pada keadaan tersebut.
Penelitian ini dilakukan untuk mengetahui apakah implantasi estradiol sekali selama penelitian dengan dosis 7 mg berpengaruh terhadap perangai pertumbuhan sel tumor transpiantabel kelenjar susu mencit GR, serta terhadap imunitas humoral mencit tersebut. Mencit yang digunakan adalah mencit betina yang pada awal penelitian berumur 6 bulan dan ditumbuhi (diinokulasi) sel tumor kelenjar susu.
Mencit dibagi ke dalam 2 kelompok yaitu kelompok kelola yang terdiri atas mencit bertumor kelenjar susu tidak diimplantasi estradiol dan kelompok perlakuan yang diimplantasi estradiol. Dengan menganalisa data volume tumor pada saat tumor berumur 1 minggu dan 2 minggu, diketahui bahwa implantasi estradiol tidak meningkatkan pertumbuhan tumor. Sedangkan dari analisa kadar imunoglobulin diketahui bahwa tidak ada pengaruh implantasi estradiol terhadap kadar Ig G dalam serum mencit. Sebaliknya transplantasi tumor ada pengaruhnya terhadap kadar Ig G serum mencit.
Pengaruh implantasi estradiol terhadap kadar Ig A pada serum mencit juga tidak bermakna. Tetapi transplantasi sel tumor justru menurunkan kadar Ig A dalam serum mencit. Kadar Ig M serum tidak dipengaruhi baik oleh implantasi estradiol maupun transplantasi sel tumor."

Background: Transthoracic needle core biopsy is one of biopsy method of intrathoracic tumors to gain histopathology sample for treatment decision. We performed CT image-guided transthoracic core biopsy in operation theatre for patient who are not able to/tolerate lie down position. Unfortunately, there are still no diagnostic accuracy study in Indonesia.
Objective: to aim diagnostic accuracy of CT image-guided transthoracic needle core biopsy in operating theatre for intrathoracic tumors.
Methods: All patients underwent CT image-guided transthoracic needle core biopsy since January 201-December 2019 are review retrospectively. Eighteen gauge automated core devices were used, and guided by CT image, core biopsy results were divide in to malignant, non-malignant, and non-diagnostic. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy are main outcome to describe diagnostic accuracies.
Results: This study enrolled 105 subjects which had sensitivity of 83,1%, specificity of 100%, positive predictive value of 100%, negative predictive value of 71%, and diagnostic accuracy of 86,7% for intrathoracic malignancies. Complications of pneumothorax are 4,8% and hemothorax are 1%. No mortality was reported.
Conclusion: CT image-guided transthoracic needle core biopsy in operating theatre for intrathoracic tumors had 86,7% of diagnostic accuracy, and a relatively safe procedure.

"[ABSTRAK
Kanker payudara adalah penyakit multifaktor yang mengakibatkan insiden kematian wanita tertinggi di dunia. Pengobatan kanker payudara berupa pembedahan, radioterapi, dan kemoterapi memiliki efek samping sehingga perlu pengobatan alternatif, salah satunya menggunakan bahan herbal. Daun sirsak (Annona muricata Linn) dilaporkan memiliki efek antitumor dan sitotoksik, tetapi penelitian in vivo terhadap kanker payudara masih sedikit, dibutuhkan penelitian lanjut mengenai efektivitas dan jalur penghambatan daun sirsak terhadap berbagai kanker. Penelitian ini bertujuan untuk mengetahui daya hambat dan dosis efektif ekstrak metanol daun sirsak (Annona muricata Linn) terhadap pertumbuhan tumor payudara mencit C3H secara in vivo. Sebanyak 30 ekor mencit galur C3H yang ditransplan dengan tumor payudara dari mencit C3H donor bertumor, dibagi dalam 5 kelompok perlakuan, yaitu kontrol negatif hanya diberi pelarut CMC 0,5%, kontrol positif diberi doksorubisin, kelompok pemberian ekstrak daun sirsak dosis 15, 30, dan 45 mg/kg BB. Setiap mencit dicekok ekstrak daun sirsak 0,2 cc per hari selama 21 hari, sedangkan kelompok kontrol positif diberikan doksorubisin secara intra vena 0,03 μg/20g BB seminggu sekali selama 21 hari. Panjang dan lebar tumor diukur di awal dan seminggu sekali selama perlakuan untuk mendapatkan data volume tumor. Pada akhir penelitian mencit dinekropsi, tumor mencit ditimbang dan dilakukan pewarnaan AgNOR untuk diukur aktivitas proliferasi sel. Hasil uji Anova menunjukkan perbedaan yang bermakna (p=0,007) antar perlakuan terhadap volume tumor akhir dan terhadap aktivitas proliferasi (p=0,001). Uji Kruskal Wallis terhadap berat tumor menunjukkan tidak ada perbedaan yang bermakna antar perlakuan (p=0,03). Hasil uji korelasi Spearman secara bermakna (p=0,03) menunjukkan ada korelasi positif antara aktivitas proliferasi sel dengan pertumbuhan volume tumor dengan kekuatan korelasi yang lemah (r=0,39). Disimpulkan bahwa ekstrak metanol daun sirsak (Annona muricata Linn) dapat menghambat laju pertumbuhan volume tumor dan aktivitas proliferasi sel kanker payudara mencit C3H dan optimum penghambatan pada dosis 30 mg/kg

ABSTRACT
BB.;Breast cancer is a multifactor disease that has been a leading cause of woman?s mortality. Treatments for breast cancer such as surgery, radiotherapy, and chemotherapy have their own side effects, so that alternative treatments such as herbal medicine are needed. Soursop leaf (Annona muricata Linn) has been reported to have antitumor and cytotoxic effects, but only few conducted in vivo, an advanced research is needed to find the effectiveness and the inhibition pathway of the soursop leaf. The purpose of this research is to find out the inhibition capacity and the effective dose of soursop leaf methanol extract (Annona muricata Linn) against the development of C3H mice?s breast cancer in vivo. There were thirty mice of C3H strain which were transplanted with breast tumor and they were divided into five groups consisting of negative control group which was given only solvent CMC 0.5%, a positive control group which was given doxorubicin, a dose group of 15 mg/kg BB, a dose group of 30 mg/kg BB, and a dose group of 45 mg/kg BB. Each mouse was given 0,2 cc soursop leaf extract every day for 21 days while the positive control group was given doxorubicin 0,03 μg/20 gram BB once a week for 21 days intravenously. The length and the width of the tumor were measured at the beginning and also measured once a week during the experiment process to gain the data of the tumor volume. At the end of the research, the tumor of the mice was lifted and weighed and it was stained by AgNOR to measure the proliferation activity of the cell. The Anova result showed that there was a significant difference (p=0,007) between treatment against the development of tumor which was marked by the decrease of the tumor volume and proliferation activity (p=0,001). The Kruskal Wallis result showed that there was no significant difference (p<0,33) in the tumor weight. Spearman correlation study significantly (p=0,03) indicated that there was a positive correlation between the cell proliferation activity and the growth of the tumor but in a weak correlation (r=0,39). Therefore, it could be concluded that the methanol extract of soursop leaf (Annona muricata Linn) can inhibit the growth rate of tumor volume as well as the proliferation activity of the breast cancer cell of C3H mice and it worked optimally at 30 mg/kg BB dose.;Breast cancer is a multifactor disease that has been a leading cause of woman?s mortality.

"[ABSTRAK
Latar belakang: Respons tumor setelah pemberian sitostatik sebagai kemoterapi neoajuvan pada pasien kanker payudara masih belum memuaskan dan respons tumor baru dapat dinilai setelah siklus ke-3; untuk mengurangi efek samping sitostatik dan penghematan biaya bagi yang tidak respons dibutuhkan faktor prediksi respons tumor lebih awal.
Tujuan penelitian: Untuk mengetahui apakah perubahan rasio choline/water pada pemeriksaan magnetic resonance spectroscopy (MRS) dapat digunakan sebagai faktor prediksi awal respons tumor pasien kanker payudara yang memperoleh sitostatik sebagai kemoterapi neoajuvan dan menganalisis korelasi persentase perubahan rasio choline/water eksternal dengan internal.
Bahan dan cara: Penelitian dilaksanakan di Rumah Sakit Umum Pusat Nasional Cipto Mangunkusumo (RSCM) pada bulan Agustus 2011 sampai April 2014. Subjek memperoleh sitostatik sebagai kemoterapi neoajuvan. Pemeriksaan MRI/MRS 1,5 T dilakukan sebelum sitostatik I, 20 atau 21 hari setelah sitostatik I dan setelah sitostatik III, menggunakan program syngo-GRACE untuk MRS. Tumor diukur berdasarkan RECIST 1.1. Respons tumor ≥ 30% dinyatakan positif, dan < 30% dinyatakan negatif. Hasil: Diperoleh 40 subjek dengan kanker payudara ukuran tumor ≥ 5 cm tanpa ulkus respons tumor positif 47,5%, peningkatan rasio choline/water eksternal 35% dan choline/water internal 42,5%. Peningkatan rasio choline/water eksternal pada MRS I- MRS II pada hari ke-20 atau ke-21 setelah pemberian sitostatik 1 menunjukkan respons tumor positif, RR=0,49 (IK 0,26-0,90) terutama untuk stadium < IIIC. Pada peningkatan rasio choline/water internal RR=0,54 (IK 0,28-1,04) dan penurunan nilai Apparent Diffusion Coefficient (ADC) RR= 0,51 (IK 0,23-1,13), didapatkan hubungan yang sama tetapi lebih lemah. Didapatkan pula korelasi sedang arah positif antara persentase perubahan rasio choline/water eksternal dengan persentase perubahan rasio choline/water internal (r=0,572, p=0,000). Derajat keganasan, Ki67, Bcl2 dan MVD tidak dapat digunakan sebagai faktor prediksi respons tumor. Pada Ki67 sama dengan atau lebih dari 14%, masih diperoleh repons tumor positif sedangkan pada Ki67 kurang dari 14%, tidak ditemukan respon tumor positif.
Simpulan: Peningkatan rasio choline/water eksternal pada MRS I-MRS II pada hari ke-20 atau ke-21 setelah pemberian sitostatik 1 sebagai kemoterapi neoajuvan dapat memprediksi pengecilan tumor setelah sitostatik III sama dengan atau lebih besar dari 30% terutama untuk stadium < IIIC. Perubahan rasio choline/water eksternal dan internal dapat digunakan untuk memprediksi respons tumor setelah pemberian sitostatik.;

ABSTRACT
Background : Cytostatics administration as neoadjuvant chemotherapy does not provided satisfactory tumor response in breast cancer patients and could be asses after 3rd cycle. To minimize the side effects and cost of cytostatics, early predictive factor of tumor response following neoadjuvant therapy in breast cancer patients is required. Objectives: The purpose of this study was, to asses of choline/water ratio by using
magnetic resonance spectroscopy (MRS) as an early predictive factor of cytostatics response after neoadjuvant therapy in breast cancer patients, secondly to analyze the correlation between external choline/water ratio and internal choline/water ratio.
Material and method: This study was conducted at Cipto Mangunkusumo National General Hospital since August 2011 to April 2014. Subjects received cytostatics as neoadjuvant chemotherapy underwent MRI/MRS prior to cytostatics I, 20/21 days after having cytostatics I and after cytostatics III. MRI 1.5 T was used for MRI examination and syngo-GRACE program for MRS. Tumor measurement was based on RECIST 1.1, tumor response of ≥ 30% is considered positive, and < 30% is considered negative.
Results: Among 40 non-ulcerating breast cancer subjects with tumor size of more or equal to 5 cm, 47.5% show positive response. MRS I and II showed escalation of external choline/water ratio on days 20/21 after the introduction of cytostatic I as neoadjuvant treatment, which could be used to predict tumor shrinkage after cytostatic III as high as 30% or more, RR = 0.49 (CI 0.26 - 0.90), especially for < IIIC stage. Changes of internal choline/water ratio, RR= 0.54 (CI 0.28 - 1.04) and Apparent Diffusion Coefficient (ADC) changes, RR= 0.51 (CI 0.23-1.13) show similar result but less related. A positive moderate correlation between changes of external choline/water ratio and changes of internal choline/water ratio is seen (r=0,572, p=0,000). No correlation between degree of malignancy, Bcl2, Ki67 dan MVD with tumor response. Changes of choline/water ratio combined with Ki67 higher than or equal with 14% could give positive tumor response, on the other hand, declining of choline/water ratio combined with Ki67 less than 14%, no positive tumor response could be found. Conclusion: Increased of external choline/water ratio on MRS I-MRS II on day 20 or 21 following cytostatic 1 as neoadjuvant chemotherapy can predict tumor shrinkage following cytostatic III of equal or more than 30%, especiallyfor < IIIC stage. Changes of external and internal choline/water ratio could be used to predict tumor response following cytostastic administration., Background : Cytostatics administration as neoadjuvant chemotherapy does not provided satisfactory tumor response in breast cancer patients and could be asses after 3rd cycle.
