"Latar Belakang: CXCR4 adalah reseptor kemokin G-protein 7-transmembran yang diekspresikan pada beberapa sel kanker payudara manusia pada tumor payududara primer dan metastasis yang menyebabkan migrasi sel hematopoietik dari sumsum tulang belakang ke kelenjar getah bening perifer. Penelitian-penelitian sebelumnya menunjukkan bahwa CXCR4 berkaitan dengan metastasis kelenjar getah bening aksilla. Namun, sampai sekarang, tidak ditemukan penelitian yang mengevaluasi peran CXCR4 dalam metastasis kelenjar getah bening sentinel pada kanker payudara stadium dini.Tujuan: Menentukan peran reseptor kemokin CXCR4 pada migrasi sel kanker payudara ke kelenjar getah bening sentinel.Metode: Digunakan desain studi potong lintang dengan mengevaluasi ekspresi CXCR4 pada 32 pasien kanker payudara stadium dini yang menjalani mastektomi di Rumah Sakit Umum Pusat Nasional Cipto Mangunkusumo (RSCM) pada periode Maret sampai Juni 2016. Pada seluruh kasus, ekspresi CXCR4 diperiksa dengan pemeriksaan imunohistokimia. Kemudian, dievaluasi hubungan antara ekspresi CXCR4 dengan metastasis kelenjar getah bening sentinel.Hasil: Ekspresi CXCR4 yang tinggi (cut off point ≥ 5) terdeteksi pada 19 dari 32 (59.4%) pasien kanker payudara stadium dini. Dari 19 pasien dengan metastasis kelenjar getah bening sentinel, 16 (84.21%) pasien memiliki ekspresi CXCR4 yang tinggi. Ekspresi CXCR4 berkorelasi signifikan dengan metastasis kelenjar getah bening (p < 0.01).Kesimpulan: Ekspresi CXCR4 yang tinggi berkorelasi signifikan dengan metastasis kelenjar getah bening sentinel pada pasien kanker payudara stadium dini.

Background: CXCR4 is a 7-transmembrane G-protein chemokine receptor expressed in some human breast cancer cells in both primary breast tumors and metastases that allows for migration of hematopoietic cells from the bone marrow to the peripheral lymph nodes. Previous studies have shown that CXCR4 is associated with axillary lymph node metastases. However, up until now, no studies evaluating the role of CXCR4 in sentinel lymph node metastases in early stage breast cancer patients were found.

Aim: To determine the role of chemokine receptor CXCR4 in breast cancer cells migration to sentinel lymph nodes.

Methods: A cross sectional study design was used by evaluating CXCR4 expression of 32 early stage breast cancer patients that underwent mastectomy in Cipto Mangunkusumo Hospital during the period of March to June 2016. CXCR4 expression was assessed by immunohistochemistry in all cases. Associations between CXCR4 expressions and sentinel lymph node metastases were evaluated.

Results: High CXCR4 expression (cut off point ≥ 5) was dectected in 19 of 32 (59.4%) primary early stage breast cancer patients. Of 19 patients with sentinel lymph node metastases, 16 (84.21%) had high expression of CXCR4. The expression of CXCR4 is significantly associated with sentinel lymph node metastases (p < 0.01).

Conclusions: High expression of CXCR4 was significantly correlated with sentinel lymph node metastases in early stage breast cancer patients."

"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."

"Latar Belakang: Kanker payudara merupakan jenis kanker yang paling umum terjadi pada wanita dan penyebab kematian kanker yang paling sering terjadi. Status kelenjar getah bening (KGB) amerupakan faktor prognostik dan penentu pilihan tatalaksana pasien kanker payudara. Biomarka untuk memprediksi metastasis KGB sampai saat ini belum akurat. Beberapa biomarka yang berhubungan dengan agresivitas dan prediksi metastasis yaitu CD44 (Cluster of Differentiation 44) dan MT1-MMP (Membrane Type 1- Matrix Metalloproteinase). Ekspresi CD44 dan MT1-MMP yang tinggi berhubungan dengan sifat yang lebih agresif dan prognosis yang buruk sehingga dibutuhkan biomarka tumor yang dapat memberikan informasi adanya metastasis KGB.Tujuan: Penelitian ini bertujuan untuk mengetahui hubungan ekspresi CD44 dan MT1-MMP pada metastasis kelenjar getah bening karsinoma payudara invasif NST.Metode: Penelitian analitik observasional dengan desain potong lintang pada sediaan operasi mastektomi kasus karsinoma payudara invasif NST di RSCM periode Januari 2019 sampai Juni 2020.

Background: Breast cancer is the most common type of cancer in women and the most common cause of cancer death. Lymph node status (KGB) is a prognostic factor and determinant of treatment options for breast cancer patients. The biomarker for predicting lymph node metastasis is not accurate until this time. Several biomarkers associated with aggressiveness and metastatic prediction are CD44 (Cluster of Differentiation44) and MT1-MMP (Membrane Type 1-Matrix Mettaloproteinase). The high expression of CD44 and MT1-MMP is associated with a more aggressive nature and poor prognosis. The tumor biomarkers are needed to provide information on the presence of lymph node metastases.

Aims: This study aims to determine the relationship between CD44 and MT1-MMP expression on lymph node metastases of invasive breast cancer NST.

Method: An observational analytic study with a cross-sectional design on a mastectomy operation for invasive breast carcinoma NST cases at RSCM from January 2019 to June 2020. The study sample was divided into 2 groups, 24 cases of NST invasive breast carcinoma with lymph node metastases and 24 cases of invasive breast carcinoma NST without lymph node metastases. The research sample was taken by simple random sampling of cases that met the inclusion criteria and did not include the exclusion criteria. CD44 and MT1-MMP immunohistochemical staining were performed and the number of cells stained positively was calculated. Chi-Square and Kruskal Wallis statistical analysis was performed between the two groups.

Results: There was a significant difference in the expression of CD44 in invasive breast carcinoma NST with and without lymph node metastases (p = 0.009). There was a significant difference in the expression of MT1-MMP in invasive carcinoma of No Special Type breast carcinoma with and without lymph node metastases (p = 0.032). And there is a relationship between CD44 and MT1-MMP overexpression in lymph node metastases (p = 0.000)

Conclusion: There was a significant relationship between CD44 and MT1-MMP expression in invasive breast carcinoma NST and lymph node metastasis status."

"Data epidemiologi menunjukkan bahwa dari semua keganasan tiroid, sekitar 80% hingga 85% di antaranya adalah karsinoma tiroid papiler (KTP). Biomarker untuk memprediksi metastasis KGB leher kini mulai banyak diteliti pada pasien KTP seperti matrix metalloproteinase (MMP) dan vascular endothelial growth factor (VEGF). Meskipun belum terdapat kesepakatan diagnostik terhadap MMP-9 dan VEGF-C sebagai prediktor metastasis KGB pada KTP, beberapa studi telah menunjukkan hubungan keduanya terhadap metastasis KGB. Penelitian ini bertujuan untuk mengetahui hubungan antara MMP-9 dengan VEGF-C pada metastasis KGB leher pada pasien KTP. Peneliti melakukan studi desain potong lintang di RSUPN Cipto Mangunkusumo, Jakarta Pusat. Pasien yang terdiagnosis KTP berdasarkan pemeriksaan histopatologi diinklusi dalam penelitian ini. Pasien yang telah terbukti memiliki metastasis jauh dan data tidak lengkap dieksklusi dalam penelitian. Ekspresi MMP-9 dan VEGF-C diteliti di Laboratorium Patologi Anatomi FKUI/RSCM. Sebanyak 62 pasien diinklusi dalam penelitian ini, dengan proporsi 80,6% perempuan dan 19,4% laki-laki. Ekspresi MMP-9 ditemukan lebih tinggi pada kelompok metastasis (p<0,001). Hal yang sama juga terjadi pada perbedaan median ekspresi VEGF-C, yang mana median ekspresi penanda ini pada kelompok metastasis lebih tinggi dibandingkan non-metastasis (p<0,001). Peneliti menemukan bahwa terdapat korelasi positif dan bermakna antara H-score MMP-9 dan VEGF-C, dengan koefisien korelasi 0,618. Terdapat hubungan yang bermakna antara ekspresi MMP-9 dan VEGF-C dengan kejadian metastasis KGB leher pada pasien KTP. Ekspresi MMP-9 dan VEGF-C ditemukan lebih tinggi pada kelompok metastasis. Peningkatan ekspresi MMP-9 juga berkorelasi positif dengan peningkatan ekspresi VEGF-C.

Approximately 80% to 85% of thyroid malignancies were papillary thyroid carcinoma (PTC). Biomarkers to predict cervical lymph node metastases have now begun to be widely studied in PTC patients, such as matrix metalloproteinase (MMP) and vascular endothelial growth factor (VEGF). Although there was no diagnostic agreement on MMP-9 and VEGF-C as predictors of lymph node metastasis in PTC, several studies have shown an association between the two for lymph node metastasis. This study aims to determine the relationship between MMP-9 and VEGF-C in cervical lymph node metastases in PTC patients. A cross-sectional design study was conducted at Cipto Mangunkusumo General Hospital, Jakarta. Patients diagnosed with PTC based on histopathological examination were included in this study. Patients with distant metastases were excluded from the study. The expression of MMP-9 and VEGF-C was investigated at the Anatomical Pathology Laboratory FKUI/RSCM. A total of 62 patients were included in this study, with 80.6% female and 19.4% male. The MMP-9 expression was found to be higher the metastatic group (p<0.001). The same results were also found in VEGF-C expression, where the median expression of this marker in the metastatic group was higher than the non-metastatic group (p<0.001). We found a significant and positive correlation between the H-score of MMP-9 and VEGF-C (correlation coefficient of 0.618). There is a significant relationship between the expression of MMP-9 and VEGF-C with the cervical lymph node metastases in PTC patients. The MMP-9 and VEGF-C expression was higher in the metastatic group. The increased MMP-9 expression is also positively correlated with increased VEGF-C expression."
