Didapatkan harapan yang menggembirakan dari kelompok tumor yang tidak dapat direseksi menjadi dapat direseksi setelah diberikan radiasi pra bedah yaitu sebesar 40%. "

"Kaitannya dengan ekspresi protein MLH1, MSH2, dan SMAD4, dan membandingkannya dengan pasien kanker kolorektal usia di atas 60 tahun.Metode: Data rekam medis pasien kanker kolorektal usia di bawah 40 tahun dan usia di atas 60 tahun , dikumpulkan dari 3 rumah sakit: Jakarta, Makasar, dan Bandung. Kelompok etnis dipilih dari suku bangsa Jawa, Makasar (Sulawesi Selatan, dan Minangkabau (Sumatera Barat) yang dikonfirmasi berdasarkan kuesioner. Pada spesimen tumor dilakukan pemeriksaan histopatologi, gradasi tumor, serta pemeriksaan imunohistokimia untuk penentuan ekspresi protein MLH1 dan MSH2 untuk menilai mutasi instabilitas mikrosatelit. Ekspresi protein SMAD4 diperiksa untuk memastikan bahwa jaringan tumor tidak berasal dari instabilitas mikrosatelit.Hasil: Telah dikumpulkan 121 penderita kanker kolorektal dari etnis Sunda, Jawa, Makasar, dan Minangkabau. Derajad keganasan antara pasien muda dan pasien tua berbeda secara bermakna (p = 0.001). Pewarnaan imunohistokimia untuk protein MSH2 dan MLH1 yang dilakukan pada masing-masing 92 dan 97 pasien, menunjukkan tidak terdapat perbedaan bermakna dalam hal ekspresi MLH1 dan MSH2 dan gradasi tumor, yang berarti tidak ada hubungan antara instabilitas mikrosatelit dan derajad tumor.Kesimpulan: Karakter kliniko patologi kanker kolorektal pada penduduk asli Indonesia, tidak berbeda antara pasien usia muda (< 40 tahun) dan pasien usia tua (>60 tahun) pada kelompok etnis yang sama. Juga tidak terdapat perbedaan dalam ekspresi protein MSH2 dan MLH1, yang merupakan indikator instabilitas mikrosatelit.

Aim: To obtain clinicopathological characteristics of colorectal cancer among young native Indonesians and to assess MLH1, MSH2, and SMAD4 protein expressions, comparing them with a matched population of colorectal cancer patients aged 60 years old and older.

Methods: Medical records of colorectal cancer patients aged 40 years or younger and 60 years or older from several hospitals in three Indonesian cities ? Jakarta, Makassar, and Bandung - were reviewed. The ?native? ethnic groups were selected from those originating from Java, Makassar (South Celebes), Miinangkabau (West Sumatra). Ethnicity of 121 colorectal carcinoma patients was confirmed by fulfilling requirements in a questionnaire. Tumor specimens of those patients underwent evaluation for histopathology, tumor grading as well as immunohistochemical analysis to assess MLH1, MSH2 protein expressions to detect microsatellite instability mutation pathway and SMAD4 protein expression to reconfirm that the specimens were not microsatellite instability origin.

Results: There were 121 colorectal carcinoma cases of Sundanese, Javanese, Macassarese and Minangkabau ethnic group. This study indicated that colorectal cancer has statistically different grade (p = 0.001) between the young and the older patients. Immunohistochemical staining for MSH2 protein and MLH1 were done for 92 and 97 specimens respectively. There was no significant difference between the expressions of MLH1 and MSH2 on tumor grading, indicated there was no correlation between microsatellite instability and tumor grading in this study.

Conclusion: Colorectal cancer in young native Indonesian patients (40 years old or less) was not different in clinicopathological characteristics compared to older patients (60 years old or more) in similar ethnic groups. There was also no difference in MSH2 and MLH1 protein expressions, important indicators of microsatellite instability."

"Kecemasan merupakan perasaan yang tidak jelas tentang keprihatinan dan kekhawatiran karena ancaman pada sistem nilai atau pola keamanan seseorang.Kanker kolorektal dapat dideteksi dengan beberapa pemeriksaan dan salah satunya adalah dengan kolonoskopi. Tindakan kolonoskopi menimbulkan keoemasan yang diakibatkan karena takut akan hasil dari kolonoskopi dan hasil patologi anatomi.

"[ABSTRAKPendahuluan : Kanker kolorektal termasuk salah satu morbiditas terbanyak di Indonesia dengan hasil terapi yang cenderung memprihatinkan untuk stadium lanjut lokal. Oleh karena itu diperlukan kemoradiasi neoajuvan yang merupakan terapi standar sesuai guideline untuk kanker rektum stadium lanjut lokal, meskipun demikian espons yang dihasilkan sangat bervariasi dan dipengaruhi oleh berbagai faktor, termasuk hipoksia jaringan. Osteopontin adalah penanda hipoksia endogen yang berkorelasi signifikan dengan tekanan oksigen tumor. Osteopontin juga merupakan penanda hipoksia kronis yang lebih akurat dibandingkan Carbonic Anhydrase IX (CAIX), Glucose Transporter 1 (GLUT1), dan Lactate Dehydrogenase A (LDH A) tetapi belum pernah dilakukan penelitian yang mengukur kadar OPN secara kuantitatif pada jaringan kanker rektum serta mengkorelasikannya dengan respons pengecilan tumor pada kemoradiasi neoajuvan.Metode dan Materi: Dilakukan skrining data pasien dari Rekam Medis Departemen Radioterapi. Empat belas pasien yang memenuhi kriteria inklusi dan eksklusi dianalisis retrospektif dari bulan Februari sampai dengan bulan Mei 2015. Pencitraan radiologi pasca kemoradiasi dibandingkan dengan sebelum kemoradiasi, sementara jaringan rectum didapatkan dari blok parafin yang didapatkan dari biopsi sebelum kemoradiasi. Evaluasi radiologi diukur menggunakan kriteria RECIST 1.1. Kadar OPN diperiksa menggunakan metode ELISA dan diukur menggunakan spektrofometer.Hasil : Rerata kadar OPN adalah 0.5678 ± 0.26 ng/mL. Terdapat korelasi berbanding terbalik yang kuat (r= -0.630, p= 0.016) antara kadar OPN dan pengecilan tumor. Nilai ambang batas OPN ≥0.538 ng/mL memprediksikan ketidakresponsifan terhadap kemoradiasi neoajuvan dengan tingkat sensitivitas 100% dan spesifisitas 81,8%. Meskipun demikian, tidak terdapat korelasi antara kadar OPN dengan Hemoglobin.Kesimpulan : Penelitian ini menunjukkan bahwa hipoksia terdapat pada pasien dengan kanker rektum stadium lanjut lokal dan merupakan karakter yang menandai turunnya respons pengecilan tumor terhadap kemoradiasi neoajuvan. Kadar OPN yang makin tinggi menunjukkan kondisi hipoksia yang lebih buruk dan respons yang lebih buruk untuk pengecilan tumor.

ABSTRACTIntroduction: Colorectal carcinoma is one of the common cancer in Indonesia with concerned clinical outcome for locally advanced stage, therefore neoadjuvant chemoradiation (CRT) is needed. Neoadjuvant CRT is the mainstay treatment for locally advanced rectal carcinoma, however the response is varied due to many factors, including tissue hypoxia. Osteopontin (OPN) is an emerging endogen hypoxic marker with significant correlation with tumor pO2, also more accurate chronic hypoxic marker compared to Carbonic Anhydrase IX (CAIX), Glucose Transporter 1 (GLUT1), and Lactate Dehydrogenase A (LDH A) but there's no research that measured OPN quantity in rectal cancer tissue and correlate it with tumor shrinkage response in neoadjuvant CRT.Methods and Materials: Patients? data was screened from Radiotherapy Department Medical Record Archieves. Fourteen patients that meet the inclusion and exclusion criteria were analyzed retrospectively from February to May 2015. Radiology imaging post CRT compared to the imaging pre CRT, while the rectum tissue obtained from Formalin-Fixed Paraffin Embedded (FFPE) tissue from biopsy sampling before CRT. Radiology evaluation was measured using RECIST 1.1. OPN level was conducted using ELISA method and measured with spectrophotometry.Results: The mean OPN concentration is 0.5678 ± 0.26 ng/mL. There was a significant strong negative correlation (r = -0.630, p= 0.016) between the OPN level and tumor shrinkage. OPN cut off value ≥0.538 ng/ml predicts non-responsiveness of neoadjuvant CRT with 100% sensitivity and 81.8% specificity. However, there is no correlation between OPN concentration and Hemoglobin concentration.Conclusion: This study showed that hypoxia occurs in patients with locally advanced rectal carcinoma, and characterizes decreasing tumor shrinkage response in neoadjuvant CRT. Higher level of OPN suggests worse level of hypoxic condition and worse response of tumor shrinkage., Introduction: Colorectal carcinoma is one of the common cancer in Indonesia with concerned clinical outcome for locally advanced stage, therefore neoadjuvant chemoradiation (CRT) is needed.

Aims: Rectal cancer cases are the second highest gastrointestinal cancer with a total of 14,122 and new cases (4.65%) of all cancer cases, with 6,827 fatalities in Indonesia. A standardized treatment in the management of rectal cancer in Indonesia is needed. In 2016, The National cancer control committee (KPKN) issued the National Guidelines for Colorectal Cancer Medicine Services as a guide in therapy, which was implemented in A National health center (RSCM) as a Clinical Practical Guide (PPK) for Colorectal Cancer. This study objected to assess adherence in the management of rectal cancer and its relationship with patient survival.

Method: This retrospective cohort study assessed the rectum cancer patients undergoing radiotherapy in the RSCM period January 2017-June 2018, with the criteria of non-metastatic patient inclusion, undergoing Neoadjuvant radiation therapy in RSCM, and using government insurance. Adherence to guidelines is assessed using PPK Colorectal 2016 as a reference to compliance therapeutic sequence, compliance interval therapy time, and compliance with therapeutic conformity of each modality.

Results: There are 30 patients include this study, with an average age of 48 ± 12 years. The majority of patients diagnosed with stage IIIC. The overall survival of the patient in 2 years is 43.3%. The proportion of 2 years in the group receiving therapeutic adherence is 50% while the group who did not get therapeutic adherence was 42.3% (P = 1), overall compliance was 13.3%, there is a trend of survival that looks better for the adherence group than the disobedient group, although statistically not significant (P = 0.317)."
