"Respons tumor terhadap radiasi dipengaruhi oleh berbagai faktor yang dapat digolongkan ke dalam faktor intrinsik yang bersifat genetik dan faktor-faktor lingkungan mikro (microenvirontment) yang disebut faktor epigenetik. Faktor intrinsik dapat ditunjukkan dengan 'predictive assay' yang dapat memperlihatkan sensitivitas individual tumor. Faktor epigenetik terdiri dari berbagai faktor termasuk hipoksia, vaskularisasi dan fraksi pertumbuhan. Dan berbagai penelitian dapat ditunjukkan hubungan antara beberapa faktor itu dengan respons tumor, maupun antara ketiga faktor tersebut. Dapat diasumsikan bahwa faktor hipoksia, vaskularisasi dan fraksi pertumbuhan merupakan indikatorindikator Iingkungan tumor yang dapat merupakan prediktor terhadap respons radiasi pada jaringan tumor tersebut. Pada penelitian ini, fraksi pertumbuhan tumor akan diteliti kaitannya dengan respons tumor dan pemanfaatannya dalam pengobatan gabungan untuk meningkatkan respons pada tumor yang mempunyai prognosis buruk. Berdasarkan asumsi bahwa tumor dengan fraksi pertumbuhan rendah relatif hipoksik, maka dilakukan pengobatan gabungan radiasi dengan MMC, suatu sitostatika yang bekerja efektif dalam keadaan hipoksik pada kelompok-kelompok tumor yang sudah digolongkan ke dalam fraksi pertumbuhan yang rendah dan yang tinggi. Pemilahan pasien berdasarkan besarnya fraksi pertumbuhan dilakukan dengan pemeriksaan imunohistokimia pada jaringan biopsi segar penderita kanker leher rahim menggunakan antibodi monoklonal Ki-67. Penderita KLR yang diteliti adalah penderita stadium lanjut lokal (stadium II b sampai III b menurut FIGO) yang datang ke Sub Bagian Onkologi Bagian Obstetri dan Ginekologi FKUI/RSCM dan kemudian dikirim ke Sub Bagian Radioterapi Bagian Radiologi FKUI/RSCM

Response of tumors toward radiation is affected by various factors that can be classified as intrinsic factors, which are genetic, and epigenetic factors, which are micro environment. The intrinsic factors can be demonstrated through a "predictive assay" which can show the sensitivity of individual tumor.Epigenetic factors consist of many factors including hypoxia, vascularization, and growth fraction. From results of many studies, can' be shown that there is a relation between these last factors with response of tumor. There is also relation among these three factors. We can assume that hypoxia, vascularization and growth fraction are indicators of tumor's environment which can also be predictors of response to radiation in tumor tissue.In this study, the rate of tumor growth will be studied in it's relation to tumor's response and the uses in combined treatment to increase the response of tumors with bad prognosis.Based on an assumption that tumors with low growth fraction are relatively hypoxic, combination of radiation with MMC is used, a cytostatic agent that effectively work on hypoxic condition in groups of tumors which have been classified as having low growth fraction. Patients grouping were performed based on the growth fraction as seen in immunohisto chemistry examination on fresh biopsy tissue of patients with cancer of cervix, using Ki-67 monoclonal antibody. Those patients of cancer of the cervix included in this study were patients in locally advanced stages (stage IIb - IIIb by FIGO classification), who came to Oncology Sub Department of the Department of Obstetric and Gynecology Faculty of Medicine University of Indonesia/Dr. Cipto Mangunkusumo Hospital, and referred to Radiotherapy Sub Department of the Department of Radiology at the same institute.After going through inclusion and exclusion criteria, 146 patients were found to be suitable for evaluation with the prescribed protocol. The patients were sorted into 4 groups according the growth fraction and type of treatment to be performed. Group I and Group II were patients with Ki-67 index less than 40% with a difference that Group I underwent radiation therapy only, while Group II was treated with combination of radiation therapy and MMC. Group III and IV were patients with Ki-67 index 40% or higher, with a difference that Group III underwent radiation therapy only, while Group IV was treated with combination of radiation therapy and MMC. The 40 % Ki-67 criterion was determined based on results of preliminary study which set the level around 40%.The radiation therapy consisted of external radiation to the pelvis area in 28 sessions with a dose of 180 cGy per sessions or 5040 cGy total dose given in around 5.5 weeks. After a 1 - 2 week rest, radiation therapy were continued in the form of intra cavitary radiation using High Dose Rate (HDR) system in 2 sessions, I week apart, each in a dose of 850 cGy, giving a total dose of 1700 cGy. A small number of patients (42 patients) were given with Low Dose Rate (LDR) intra cavitary system in similar session and interval with those patients with HDR system. The dose was 1300 cGy per session or total dose of 2600 cGy being equal to the total dose of 1700 cGy in HDR system. Mitomycin-C was given in the combined treatment groups, with a dose of 15 mglm2, as a bolus injection intravenously, at the first day of external radiation and the first intracavitary insertion.Routine blood examinations were performed to each patient before treatment and once a week until the radiation therapy were completed. Liver function tests were performed before treatment, at the end of external radiation and after all radiation therapy completion."

"Karsinoma serviks uteri merupakan tumor ganas yang sering ditemukan di Indonesia dan pada umumnya penderita datang dalam keadaan ianjut dimana radioterapi merupakan terapi pilih. Penilaian respon radiasi dapat dipelajari secara klinis maupun secara histopatologik. Secara histopatologik, selama ini penilaian dilakukan secara kasar yaiutu dengan melihat ada tidak sel tumor yang viable. Respon radiasi antara lain dipengaruhi oleh tingkat prolifersi sel, penilaiannya dapat dilakukan dengan berbagai metode antara lain dengan metode Ag NOR. AgNOR merupakan Salah satu cam penilaian proliferasi sel dengan cars menghilung nuclear organizer region (NOR).Pada penelitian ini nilai AgNOR digunakan untuk melakukan hubungannya dengan derajat respon radiasi secara hisropomlogik. Penghitungan nilai AfNOR dilakukan dengan 2 cara yaitu (1) rata-rata nilai AgNOR pada nukleus (mAgNOR) dan persentase AgNOR (PAgNOR). Penilaian derajat respon radiasi secara histopalogik dilakukan menurut metode Shimosato yang membuat derajat respon radiasi dari jaringan yang resisten sampai paling sensitif terhadap radiasi dengan gradasi 1A sampai 4C.Hasil dan kesimpulan, dari 20 kasus karsinoma serviks yang diperiksa, didapatkan 2 kasus dengan derajat respon radiasi 1,5 kasus dengan derajat respon radiasi 4B dan 1 kasus dengan derajat respon radiasi 4C. Karena perbandingan kasus yang tidak seimbang, kasus-kasus ini dikemlompokkan lagi menjadi 2 kelompok yaitu: (1) kelompok denga respon radiasi baik (13 kasus) dan (2) kelompok dengan derajat respon radiasi buruk (7 kasus). Walaupun terlihat kecenderungan nilai mAgNOR yang lebih tinggi ppada kasus dengan derajat respon radiasi lebih tinggi, nilai mAgNOR yang tidak berbeda bermakna pada kelompok-kelompok yang diperiksa, kemungkinan disebabkan karena mAgNOR tidak secara sppesifik mewakili fraksi pertumbuhan yang tinggi sehingga tidak langsung terkait dengan radiosensitifitas jaringan.Dari penelitian ini ditemukan nilapAgNOR yang lebih tinggi secara bermakna pada kelompok dengan responn radiasi baik debandinglan dengan kelompok dengan derajat respon radiasi buruk (p=0,05). Hasil ini menunjukkan bahwa nilai pAgNOR lebih spesifik dan ditelti lebih lanjut dengan digabungkan dengan metoda sehic diharapkan dapat dipakai sebagai salah satu cara untuk memprediksi respon radiaso karsinogen serviks uteri.

Cervical uterine cancer is one of tlte most common malignant tumors in Indonesia, patients usually presented in an advance stage where radiotherapy is a therapy of choice. Evaluation of radiotherapy is done both clinically and histopathologcally. Ust; histopathologic assessment was done roughly bythe presence of viable tumor cells. Radio response is influenced by cell proliferation rate and the assessment can be done with methods. ie. Ag NOR method. AgNOR is one of cell proliferation marker that cour nuclcolar organizer region (NOR).

In this study, AgNOR counts was used to soc corelation with grade ofhistopathological radiation response. AgNOR counts was carried in 2 wajrs: (1) mean of AgNOR counts in the nuclei (mAgNOR0 and (2) percentag AgNOR (PAgNOR). Evaluation of histopathologic radiation response grade was a following Shimosato that made gradation radiation response from radioresistant to alt radiosensitiv tissue in IA to -1C grade.

Result and conclusion, from 20 cases of Cervical cancer studied based on Shimosato method. 2 cases were of grade 1, 5 cases of grade ZA. l case of grade 5, 2 cases of grade 49., 9 cases of grade 4B and 1 of gade 4C . Due to unequal number of cases in each group, it was grouped into 2 groups, good radiation response. which is iound in 13 cases and (2) poor radiation response a cases. Altough there is higher number mAgNOR counts irt group with higher grade radiation response. It was not statistically significant, most likely because in mAgNOR is specitically representing high growth fraction, therefore was not correlated directly with tis radiosonsitivitly. From this study, it was showed that pAgNOR counts was hit significantly in group with good radiation response compared to group with poor radia response (p=0.05).

The result showed that pAgNOR count is more speciiic, therefore it car used in more research combine with another method make this method will used as one method for the prediction of radiation response in cert-?ical uterine carcinoma."

"ABSTRAKLatar Belakang: Kanker serviks stadium lanjut lokal (IIB-IIIB) masih menjadi beban kesehatan di Indonesia saat ini. Radiasi menjadi modalitas utama terapi pada stadium ini. Programmed Death-Ligand 1 (PD-L1) merupakan sebuah ligand yang diekspresikan pada sel tumor yang terkait dengan proses immune escape. Sampai saat ini belum diketahui karakteristik kadar PD-L1 pada karsinoma sel skuamosa (KSS) serviks stadium lanjut lokal serta pengaruh radiasi terhadap ekspresinya. Penelitian ini bertujuan untuk melihat karakteristik PD-L1 intratumoral pada kanker serviks stadium lanjut lokal serta pengaruh radiasi eksterna terhadap ekspresinya. Metode: Dilakukan pemeriksaan kadar PD-L1 pada sampel biopsi serviks dengan 2 metode, yaitu Enzyme Linked Immuno Sorbent Assay (ELISA) dan immunohistokimia (IHK). Pengambilan sampel dilakukan dua kali, yaitu preradiasi dan pascaradiasi eksterna. Dilakukan analisis statistik untuk mengetahui perbedaan kadar antara sebelum dan sesudah radiasi. Selain itu dilakukan analisis untuk melihat kesesuaian antara kadar yang ditunjukkan pada metode ELISA dengan metode IHK. Hasil: Didapatkan 29 sampel KSS serviks stadium lanjut lokal yang memenuhi kriteria inklusi dan eksklusi. Dari pemeriksaan IHK, didapatkan bahwa PD-L1 diekspresikan hampir pada seluruh subjek (96,5%). Didapatkan nilai median PD-L1 ELISA preradiasi 409,19 pg/mg protein (59,80-3011,30), pascaradiasi 444,40 pg/mg protein (27,24-3217,85). Tidak didapatkan perbedaan bermakna antara kedua kelompok tersebut (p = 0,804). Pada analisis receiver operating characteristics (ROC) didapatkan nilai ELISA >400 pg/mg protein bersifat prediktif menyebabkan terjadinya penurunan kadar ELISA pascaradiasi. Terdapat kesesuaian antara kadar PD-L1 metode ELISA dengan metode IHK, dimana nilai ELISA > 499 pg/mg protein cenderung menunjukkan nilai grade 3 pada pemeriksaan IHK. Kesimpulan: PD-L1 diekspresikan positif pada KSS serviks uteri stadium lanjut lokal. Tidak terlalu jelas efek radiasi dalam menyebabkan naik-turunnya ekspresi PD-L1. Pemeriksaan ELISA mempunyai potensi untuk dipertimbangkan mewakili hasil pemeriksaan IHK, namun perlu bukti yang lebih kuat berupa penelitian dengan jumlah sampel yang lebih banyak.

ABSTRACTBackground: Locally advanced cervical cancer (IIB-IIIB) remains a health burden in Indonesia. Radiation is the main modality of therapy at this stage. PD-L1 is a ligand that is expressed in tumor cells associated with the immune escape process. Until now there is no clear characteristics of PD-L1 levels in locally advanced-stage cervical SCC and the effect of radiation on its expression. This study is aimed to look for the intratumoral PD-L1 characteristics in locally advanced cervical cancer and the effect of external radiation on its expression. Method: PD-L1 levels were examined on cervical biopsy samples using two methods, i.e. ELISA and IHC. Biopsy was carried out twice, preradiation and post-external radiation. Statistical analysis was performed to determine differences in levels between before and after radiation. In addition, an analysis was conducted to see the conformity between the levels indicated in the ELISA method and the IHC method. Results: Twenty nine samples of local advanced cervical SCC were obtained that met the inclusion and exclusion criteria. From the IHC examination, it was found that PD-L1 was expressed in almost all subjects (96.5%). The median PD-L1 concentration of ELISA PD-L1 preradiation was 409.19 pg / mg protein (59.80-3011.30), post-radiation 444.40 pg / mg protein (27.24-3217.85). No significant difference was found between the two groups (p = 0.804). In the ROC analysis it was found that ELISA values > 400 pg / mg protein were predictive to cause a decrease in postradiation ELISA levels. There is a conformality between the levels of PD-L1 ELISA method with the IHC method, where the ELISA value > 499 pg/mg of protein tends to show grade 3 values ​​on the IHC examination. Conclusion: PD-L1 was expressed positively in locally advanced cervical SCC. The effects of radiation in causing the ups and downs of the expression of PD-L1 is not very clear. ELISA examination has the potential to be considered as a representative to the results of the IHC examination, but stronger evidence is needed in the form of study with a larger number of samples."

Background: Cervical cancer is one of the leading causes of death related to malignancies. One of the contributing factor toward this high mortality rate is that patients are usually diagnosed at an already advanced stage. Radiotherapy can be used as a treatment for advanced cervical patients who cannot tolerate the side effects of chemotherapy. However, patients with cervical cancer show mixed responses to radiotherapy.

Objectives: This study aims to assess the association between CD8+ TILs density in advanced stage cervical cancer and its response to radiotherapy.

Methods: This is a case-control study. The study population were patients diagnosed with stage IIIB uterine cervix squamous cell carcinoma at the Department of Anatomical Pathology Faculty of Medicine University of Indonesia (FMUI)/Cipto Mangunkusumo Hospital (CMH) from January 1st, 2016 up to December 31st, 2021, who received definitive radiotherapy at the Department of Radiation Oncology FMUI/CMH, and had complete radiotherapy response data. Patients with complete response are classified as the response group and those with incomplete response are classified as the control group. Sampling is done consecutively. The data were statistically analyzed to assess the factors influencing radiation response.

Results: Forty cases of stage IIIB uterine cervix squamous cell carcinoma were selected, consisting of 20 cases with complete radiation response and 20 cases with incomplete response. The median CD8+ iTILs density in the complete response group was higher than in the incomplete response group (1099 cells/mm2vs 920,27 cells/mm2, p: 0,035). The recommended cut-off point for predicting radiotherapy response was 959,32 cells/mm2. No statistically significant relationship was found between tumor size, degree of differentiation, and keratinization on response to radiotherapy.

Conclusion: Higher CD8+ iTILs density was associated with better response to radiotherapy in stage IIIB uterine cervix squamous cell carcinoma."

Background: Most of the cervical cancer patients in Indonesia came with advanced stage. Therefore, the choice of treatment is radiotherapy. Although, radiotherapy does not always result in complete response. MnSOD is considered to be one the antioxidant enzyme which has the ability to work against free radicals. Its activity is expected to be acted as response predictor to radiotherapy treatment. It is hypothesized that high MNSOD activity tend to predict poor response of radiotherapy on advanced cervical cancer patients.

Objective : To investigate MnSOD activity on cervical SCC stage IIIB as a predictor of radiotherapy response.

Methods : It is a comparative cross sectional study conducted in the Gynecology Oncology Division, Obstetrics and Gynecology Department, Dr. Cipto Mangunkusumo Hospital Faculty of Medicine, University of Indonesia. Samples were collected from the tissue bank and research database. They were identified and divided into having positive or negative response to radiotherapy. In vitro experiment was conducted to measure the activity of MnSOD. Manganese superoxide dismutase was isolated using McCord and Fridovich method using RanSOD and the activity was analyzed using spectrophotometry. Data was then analyzed using SPSS.20 for comparative study.

Results : Seventy six samples were included in the study 47 61.8 with positive response and 29 38.2 with negative response on radiotherapy. Samples were then divided into having MnSOD activity of 13.126 U mL or 13.126 U mL. Univariate analysis chi square showed that there was statistically significant correlation between MnSOD activity and radiotherapy response in patients with cervical SCC stage IIIB RR 1.849 95 CI 1.075 3.178 . Survival analysis on the first year showed that patients with MnSOD activity 13.126 U mL had better survival than patients with MnSOD activity 13.126 U mL 63 vs 14 , Kaplan Meier study . Hazard ratio for overall survival was 1.055 95 CI 1.003 ndash 1.110 for patients with MnSOD activity of 13.126 U mL. Multivariate analysis showed that MnSOD activity was a strong predictor of radiotherapy response in this study.

Conclusion : This in vitro study showed that high activity of MnSOD was associated with poor response of radiotherapy for patients with cervical squamous carcinoma stage IIIB. "

Background: Cervical cancer is a malignancy that is often found in various countries in women after breast cancer. Cervical cancer is associated with a high mortality rate. FIGO recommends the use of MRI as a diagnostic and prognostic tool. The rate of tumor proliferation is related to the therapeutic response which can be determined by the value of the T2WI sequence intensity signal. Currently, there are no studies that assess the differences in SI values of T2WI sequences and the response to radiation therapy in squamous cell carcinoma type cervical cancer.

Objective: Obtain differences in the value of the T2WI sequence ratio in patients with cervical cancer squamous cell carcinoma who experienced and did not respond to therapy.

Methods: A total of 39 study subjects were subjected to pelvic MRI examinations before and after radiation therapy. The research data were taken using T2WI sequences and histological data came from EHR RSUPN Dr. Cipto Mangunkusumo. Data were analyzed using the Saphiro-Wilk normality test and paired T test.

Results: In the age group, marital status, obstetric status and FIGO classification, the results were not significant (p = 0.19, p = 0.348, p = 0.153, and p = 0.995; p> 0.05). Likewise in the response dan unresponse group with RECIST 1.1, the results were significant with p = 0.000; p <0.05), while the difference in the value of the T2WI sequence ratio, the results were not significant (p = 0.436, p> 0.05).

Conclusion: There is no difference in the value of the T2WI sequence ratio in the response group and no response to therapy based on RECIST 1.1 criteria in squamous cell carcinoma type cervical cancer."
