ABSTRAK Proses perkembangan tumor pada kanker kolorektal dikaitkan dengan pentingnya peranan sistem imun. Sel tumor memiliki kemampuan untuk bertahan dalam lingkungan mikrotumor, menghindari pengenalan sistem imun, dan menekan reaktivitas sistem imun. Sistem imun adaptif memiliki peranan penting khususnya limfosit T sitotoksik (CD8) yang memiliki peran dalam mengontrol pertumbuhan tumor dan metastasis. Penelitian ini bertujuan untuk mengetahui hubungan kepadatan limfosit T CD8 dengan karakteristik klinikopatologi pada kanker kolorektal. Telah dilakukan penelitian uji diagnostik. Jenis penelitian deskriptif dengan desain serial kasus. Sampel penelitian berjumlah 41 kasus terdiri dari 19 kasus adenokarsinoma (AK), 12 kasus adenokarsinoma dengan komponen musin(ADKM), 6 kasus adenokarsinoma musinus(AM) dan 2 kasus cribriform comedo type carcinoma(CCTC). Dilakukan pemeriksaan imunohistokimia dengan antibodi CD8 dan dilanjutkan dengan penilaian kepadatan limfosit T CD8. Berdasarkan keempat tipe histopatologi mayoritas usia terbanyak ≥50 tahun, jenis kelamin laki-laki, tipe histopatologi adenokarsinoma, derajat differensiasi sedang, ukuran tumor ≥5 cm, lokasi tumor kolon kiri, kedalaman invasi T3 dan keterlibatan metastasis pada kelenjar getah bening N0 sama banyak dengan N1, tidak terdapat hubungan kepadatan limfosit T CD8 dengan karakteristik klinikopatologi adenokarsinoma kolorektal (p≥0,05). Kepadatan limfosit T CD8 tidak berhubungan dengan karakteristik klinikopatologi adenokarsinoma kolorektal
A B S T R A C TInsulinoma is a functional neuroendocrine neoplasm consisting of insulin-producingcells, which produce insulin uncontrollably, causing a hypoglycemic syndrome. TheHypoglycemic syndrome is a result of hyperinsulinemia which causes adrenergicsymptoms and neuroglycopenia. The clinical diagnosis is based on the Whipple triad,insulin, and C peptide levels in a 72-hour fasting state. Generally, insulinoma is abenign neoplasm with a proliferation index of Ki-67 <2%. On histological features, thegrowth pattern of the insulinoma is usually trabecular or solid. Some insulinomas showa tubuloacinar growth pattern with psammoma bodies. We reported one case ofinsulinoma in a 65-year-old woman, who had experienced fainting, cold sweats for 3years, especially when the patient ate late or at midnight while sleeping. A CT scanshowed a tumor mass in the pancreas possibly an insulinoma and a pancreatectomywas performed. The results of the histopathological examination are bu following peerunder Insulinoma.
