EVALUATION OF MYOMETRIAL INVASION AND CERVICAL INVOLVEMENT IN TYPE I ENDOMETRIAL CANCER USING DIFFUSION-WEIGHTED MAGNETIC RESONANCE IMAGING

Objective: Surgical procedure and adjuvant treatment of type I endometrial cancer were affected by some variables assessed preoperatively. Diffusion-weighted magnetic resonance imaging (DWI) is a promising modality in evaluating myometrial invasion and cervical involvement, investigating the diagnostic values of DWI in assessing myometrial invasion and cervical involvement. Methods: A cross-sectional study was conducted. This study involved all type I endometrial cancer patients in Dr. Cipto Mangunkusumo Hospital from April 2016 until April 2019. The depth of myometrial invasion and cervical involvement was examined using 1.5-T MR unit. The result was compared to the surgical pathologic findings as the reference standard. Results: 34 types I endometrial cancer patients were enrolled in this study. The sensitivity of DWI in evaluating myometrial invasion and cervical involvement in type I endometrial cancer was 94.12% and 57.14%, while the specificity was 64.71% and 92.59%, respectively. Conclusion: DWI can provide reliable prognostic variable information about the myometrial invasion and cervical involvement in the preoperative preparation of endometrial cancer patients

Postradiotherapy Outcome on Cervical Cancer Stage IIIB Patients with and without Paraaortic Lymph Nodes Enlargement: Hasil Pascadiadioterapi pada Pasien Kanker Serviks Stadium IIIB dengan dan tanpa Pembesaran Nodus Paraaorta

Objective : To determine whether there are differences in clinical response after radiotherapy and 1 year survival in patients with advanced cervical cancer with and without enlargement of PALN.Method : An observational analytic study using a retrospective cohort method was done using consecutive sampling. The subjects of this study were all women with a primary diagnosis of stages IIB to IVB cervical cancer who came to the gynecological oncology clinic of Dr. Cipto Mangunkusumo National General Hospital and underwent MRI examination before undergoing treatment in January 2016 to May 2017Results: Among 76 subjects studied, there were 4 (5.1%) subjects who had enlarged PALN. There were no significant differences between the enlargement status of PALN and age (p = 0.829), age of first sexual intercourse (p = 0.33), parity (p = 0.642), mass diameter (p = 0.777). Patients with PALN enlargement have 2.13 times risk of having negative radiotherapy outcome (p = 0.02, OR 2.13, CI95% 1.12 – 4.07). There was no difference in 1-year survival between patients with and without enlargement of PALN (median 201 vs. 293, p = 0.072).Conclusion: Patients with PALN enlargement have increased risk of having negative radiotherapy outcome (p < 0.05). There were no differences in 1 year survival between patients with advanced cervical cancer with enlargement PALN.Keywords : cervical cancer,  lymph node enlargement, paraaortic, radiotherapy.   Abstrak Tujuan: Mengetahui adakah perbedaan respon klinis pascaradioterapi dan kesintasan 1 tahun pada pasien kanker serviks stadium lanjut dengan pembesaran KGB paraaorta dibandingkan tanpa pembesaran KGB paraaorta.Metode: Penelitian ini merupakan penelitian analitik observasional dengan menggunakan metode kohort retrospektif. Pengambilan sampel dilakukan dengan cara pengambilan sampel berturut-turut. Subyek penelitian ini adalah semua perempuan dengan diagnosis primer kanker serviks stadium IIB hingga IVB yang datang ke poliklinik Onkologi Ginekologi RSUPN Dr. Cipto Mangunkusumo dan menjalani pemeriksaan MRI sebelum dilakukan terapi pada bulan Januari 2016 hingga Mei 2017.Hasil: Dari 76 subjek yang diteliti, didapatkan sebanyak 4 (5,1%) subyek yang mengalami pembesaran KGB paraaorta. Tidak didapatkan perbedaan yang bermakna antara status pembesaran KGB paraaorta dan usia (p = 0,829), usia hubungan seksual pertama (p = 0,333), paritas (p = 0,642), dan diameter massa (p = 0,777). Pasien dengan pembesaran KGB paraaorta memiliki risiko 2,13 kali lipat (p = 0,02, OR 2,13, IK95% 1,12-4,07) memiliki risiko respon terapi negatif. Tidak terdapat perbedaan kesintasan 1 tahun antara pembesaran KGB paraaorta dan tidak (median 201 vs. 293, p = 0,072).Kesimpulan Pasien dengan pembesaran KGB paraaorta memiliki risiko lebih tinggi mengalami respon radioterapi negatif. (p < 0,05). Tidak terdapat kesintasan 1 tahun antara pasien kanker serviks stadium lanjut dengan dan tanpa pembesaran KGB.Kata kunci: kanker serviks,  paraaorta,  pembesaran KGB, radioterapi

Minimal apparent diffusion coefficient value of the solid component to differentiate borderline and malignant ovarian epithelial tumours : a preliminary report

Purpose: Ovarian tumours are the second most common cause of death from gynaecological cancer. There are three types of ovarian cancer based on histopathological examination: benign, borderline, and malignant. However, it is difficult to distinguish the borderline and malignant tumours. Several studies used the apparent diffusion coefficient value to distinguish the ovarian tumour types, with various results. This preliminary report focused more on the use of the minimal ADC (mADC) value on the solid component, to differentiate borderline and malignant ovarian tumours. Material and methods: In 21 cases of borderline ovarian tumours, of which 11 were regarded as malignant and 10 were regarded as borderline following histopathological examination, the mADC value was measured by two different radiologists by using free-hand technique. The intraclass correlation coefficient (ICC) was used to measure the reliability and agreement between the two radiologists. Receiver-operating characteristic (ROC) curves were then calculated to determine the optimum cut-off point. Results: There were statistically significant (p = 0.001) of the mADC value between the borderline and malignant tumours. The intraclass correlation coefficient value showed excellent reliability and agreement between the examiners. The ROC curve showed the optimum cut-off point at 0.628 × 10-3 mm2/s (p = 0.001), which yielded 100% sensitivity and 80% specificity. Conclusions: The use of free-hand technique to measure the mADC value on the solid component can be valuable in differentiating borderline and malignant ovarian epithelial tumours. This result may assist clinicians in considering further treatment approaches
