"Latar Belakang : Pasien kanker serviks di Indonesia terbanyak dalam stadium lanjut. Terapi standarnya adalah radiasi. Respons terapi radiasi tidak selalu komplet. MnSOD merupakan garda terdepan melawan radikal bebas yang dihasilkan radiasi. Aktifitas MnSOD dipikirkan dapat digunakan sebagai prediktor respons terapi radiasi. Diperkirakan semakin tinggi aktifitas MnSOD akan semakin buruk respons radiasinya. Tujuan : Menilai aktifitas MnSOD pada biopsi KSS serviks stadium IIIB sebagai prediktor keberhasilan terapi radiasi. Metode : Penelitian potong lintang komparatif ini dilakukan di Divisi Onkologi Ginekologi, Departemen Obstetri dan Ginekologi FKUI, RSCM Jakarta dan Departemen Biokimia dan Biologi Molekuler FKUI. Dilakukan penelusuran data base penelitian sebelumnya untuk mengindentifikasi sampel respons positif dan negatif, dilanjutkan pemeriksaan aktifitas MnSOD dengan sprektrofotometri metode McCord dan Fridovich menggunakan kit RanSOD . Data komparatif yang didapat kemudian di analisis. Hasil : Didapatkan 76 sampel yang memenuhi kriteria inklusi terdiri dari respons positif 47 61,8 negatif 29 38,2 . Dilakukan kategorisasi aktifitas MnSOD dengan titik potong pada nilai 13,126 U/mL. Dengan uji chi-square didapat hubungan bermakna secara statistik antara aktifitas MnSOD pada pasien kanker stadium IIIB dengan respons terapi radiasi. Nilai RR sebesar 1,849 1.075-3.178, IK 95 . Kesintasan dengan analisis bivariat memakai metode Kaplan-Meier: pasien dengan aktifitas MnSOD cutoff < 13,126 U/mL memiliki tingkat kesintasan 1 tahun yang lebih baik 63 dibandingkan dengan pasien kanker serviks IIIB dengan nilai aktifitas MnSOD ge; 14 . Risiko kematian dengan pengujian bivariat metode regresi cox: pasien dengan aktifitas MnSOD cutoff 13,126 U/mL memiliki risiko kematian 1,055 kali IK 95 : 1,003-1,110 dibanding pasien dengan aktifitas MnSOD dibawah nilai cutoff. Dari analisis multivariat terlihat aktifitas MnSOD semakin kuat sebagai prediktor respons terapi radiasi. Kesimpulan : Aktifitas MnSOD tinggi pada jaringan KSS serviks stadium IIIB menghasilkan respons negatif dari terapi radiasi.

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. "

"Latar Belakang: Kanker ovarium epitelial merupakan jenis keganasan ovarium yang paling sering ditemukan dan bersifat agresif. Upaya melakukan deteksi dini dilakukan dengan pemeriksaan ginekologi, dikombinasi dengan pemeriksaan ultrasonografi, advanced imaging (CT-Scan, MRI) dan pemeriksaan kadar serum CA-125, namun untuk menentukan diagnosis pasti diperlukan pemeriksaan histopatologi. Tujuan: Membandingkan temuan metastasis kelenjar getah bening pada advanced imaging (CT-Scan, MRI) dengan histopatologi pada kasus kanker ovarium epitelial.dan menentukan rentang waktu antara dilakukkan advanced imaging dengan tindakan operasi. Metode: Penelitian ini bersifat kohort retrospektif. Sampel penelitian adalah pasien dengan riwayat kanker ovarium epitelial stadium awal yang sudah dilakukan limfadenektomi di RSCM pada tahun 2017-2022 dengan teknik consecutive sampling. Pengumpulan data melalui data sekunder. Data dianalisis secara univariat dan bivariat dengan uji Mc Nemar atau Kappa. Hasil: Dari karakteristik didapatkan usia rata-rata 48 tahun, paling banyak dengan jenis clear cell carcinoma (36.7%), dan ditemukan paling banyak pada ovarium kanan (43.3%). Hasil advanced imaging tidak memiliki nilai kesepakatan yang berarti dengan hasil histopatologi (Kappa value -0.01, p >0.05). Hasil paling banyak ditemukan metastasis di pelvis kiri. Rentang waktu dilakukannya operasi setelah pemeriksaan advanced imaging, paling banyak dalam waktu kurang dari 3 bulan (50.0%). Kesimpulan: Semakin cepat waktu dilakukan tindakan operasi semakin tinggi survival rate. Tidak ada hubungan yang signifikan antara ditemukannya limfadenopati pada advanced imaging dan histopatologi.

Background: Epithelial ovarian cancer is the most common and aggressive type of ovarian malignancy. Efforts aimed at early detection are gynecological examination, combined with ultrasound examination, advanced imaging (CT-Scan, MRI) and CA-125 levels, but to determine a definite diagnosis a histopathological examination is needed. Objective: To compare the findings of lymph node metastases on advanced imaging (CT-Scan, MRI) with histopathology in cases of epithelial ovarian cancer. And to determine the time interval between advanced imaging and surgery. Methods: This study used a retrospective cohort. The sample of the study was patients with a history of early-stage epithelial ovarian cancer who had undergone lymphadenectomy at RSCM in 2017-2022 by consecutive sampling technique. Data collection through secondary data. Data were analyzed univariately and bivariately with the Mc Nemar or Kappa test. Results: The features revealed that the average age was 48 years, that clear cell carcinoma was the most prevalent form (36.7%), and that it was most frequently discovered in the right ovary (43.3%). According to the study's findings, there was no significant correlation between the outcomes of advanced imaging and those of histopathology (Kappa value: -0.01, p >0.05). The results showed that most metastases were found in the left pelvis. This study evaluated the length of surgery following enhanced imaging test revealed that 50% of patients underwent surgery in less than three months on average. Conclusion: The difference between preoperative and intraoperative findings will be minimized if surgery is conducted early. There was no significant correlation between lymphadenopathy findings on advanced imaging and histopathology."
