dc.description.abstract | Colorectal cancer (CRC) is the second most common tumour in Malaysia. Universal screening for the identification of microsatellite instability/mismatch repair (MSI/MMR) status in CRC patients is recommended by several guidelines. The detection of MSI/MMR status in CRC patients is not only essential to identify Lynch Syndrome (LS), but it also has predictive and prognostic values. The study aimed to investigate the MMR and MSI status among CRC patients in Kuantan, Pahang as well as to assess the consistency between immunohistochemistry (IHC) and MSI analysis. Formalin-fixed paraffin-embedded (FFPE) tissue blocks of 123 CRC patients were retrieved for the years 2017-2018. For IHC and MSI analysis, EnVisionTM FLEX, Mini Kit, High PH, and MSI Analysis System 1.2 (Promega) were utilized, respectively. MSI analysis was performed on selected deficient mismatch repair (dMMR) and proficient mismatch repair (pMMR) cases. IHC detected 11.4% (14 out of 123) patients as dMMR and 88.6% (109 out of 123) as pMMR. MSI analysis identified 26% (13 out of 50) patients as MSI-H, 6% (3 out of 50) patients as MSI-L, and 64% (32 out of 50) patients as MSS. Both the IHC and MSI analysis showed perfect agreement (0.896, Kappa value) for the recognition of dMMR or MSI-H CRC patients while demonstrating only 4% (2 out of 50) discordant results. Almost all dMMR patients detected by IHC were recognized by MSI analysis as MSI-H except one. The significant prevalence of dMMR in current cohort support the recommendation that the assessment of MSI/MMR status should be addressed in CRC patients. The selection of the choice method may be based on the availability of the expertise and equipment. Since IHC is an affordable, a reproducible and readily available in most histopathological laboratories, it can be used as a primary screening test to detect MSI/MMR status in CRC patients. | en_US |

dc.description.abstractarabic | يعتبر سرطان القولون والمستقيم ثاني اكثر الاورام شيوعا في ماليزيا. يوصى بالعديد من الاختبارات لتحديد حاله عدم استقرار/اصلاح عدم التطابق (MSI/MMR) في مرضى سرطان القولون والمستقيم. ان الكشف عن حاله (MSI/MMR) في مرضى سرطان القولون والمستقيم ليس ضروريا فقط لتحديد متلازمه لينش (Lynch Syndrome), ولكنه يحتوي ايضا على قيم تنبؤيه و تحذیریه. هدفت هذه الدراسه الى التحقيق في( MMR and MSI) بين مرضى سرطان القولون والمستقيم في كونتان,باهانج, وكذلك لتقييم الاتساق بين طريقتي الكيمياء المناعيه (IHC) , و ((MSI. تم وضع عينات الانسجه المجمعه بالفورمالين لعدد١٢٣ حاله مرضيه بسرطان القولون والمستقيم للسنوات ٢٠١٧ و٢٠١٨. لتحليل(IHC and MSI Analysis ), تم استخدام ( EnVisionTM FLEX, Mini Kit, High PH, and MSI Analysis System 1.2 (Promega)) ) على التوالي. تم اجراء تحليل(MSI)على حالات اصلاح عدم تطابق غير محدده (dMMR) و حالات عدم التوافق الدقيق (pMMR). طريقه الكيمياء المناعيه (IHC) اكتشفت١١,٤ (١٤ من اصل١٢٣) مريضآ على انها (dMMR), و ٨٨,٦ ٪ (١٠٩ من اصل١٢٣) على انها (pMMR). حدد تحليل (MSI) ٢٦٪ (١٣ من اصل ٥٠) على انهم (MSI-H), و٦٪ (٣ من اصل٥٠ ) مريضا على انهم (MSI-L), و ٦٤٪ (٣٢ من اصل ٥٠) مريضا على انهم (MSS). أظهر كل من تحليل (IHC and MSI) اتفاقا مثاليا (0.896, kappa value) للاعتراف بمرضى (dMMR or MSI-H) مع اظهار ٤٪ فقط (٢من اصل٥٠) نتائج متناقضه. تم التعرف على جميع مرضى (dMMR) الذين اكتشفهم (IHC) من خلال تحليل (MSI) على انه (MSI-H) باستثناء واحد. يدعم الانتشار الكبير ل(dMMR) في الدراسه الحاليه التوصيه بأن تقييم حاله (MSI/MMR) يجب ان يعالج في مرضى سرطان القولون والمستقيم. قد يعتمد اختيار طريقه الاختيار على توفر الخبره والمعدات. نظرا لان (IHC) هو باسعار معقوله,وقابله للتكرار,ومتوفر بسهوله في معظم مختبرات علم الانسجه,يمكن استخدامه كاختيار فحص اولي للكشف عن حاله (MSI/MMR) في مرضى سرطان القولون والمستقيم. | en_US |
