"PURPOSE: Rectal gastrointestinal stromal tumors (GISTs) are rare. Accordingly, their clinical features are not well-documented and optimal treatment has not been established. The objective of this study is to clarify the rates and patterns of recurrence after surgical resection of rectal GISTs, with a focus on outcomes and therapeutic modalities.METHODS: The registry was designed to collect data on rectal GISTs recorded between January, 2003 and December, 2007 at 40 participating institutions of the Kinki GIST Study Group. The principal variables were the rates and patterns of recurrence of rectal GISTs. Other study variables were age, sex, tumor size, mitotic count, distance from the anal verge, tumor location, surgical procedures, surgical margins, and recurrence-free survival.RESULTS: Twenty-four cases were registered, 11 (45.8%) of which were classified as high-risk by the modified NIH criteria. Locoregional recurrence (7/23, 30.4%) was the predominant recurrence pattern after curative resection, with rates that did not differ after local excision (33.3%; 3/9) vs. extended resection (28.6%; 4/14). The recurrence rates were high (25.0%) even for patients with low-risk disease. There was only one case of recurrence among patients who received perioperative treatment with imatinib.CONCLUSIONS: Rectal GISTs showed high rates of local recurrence regardless of the surgical procedure. Perioperative treatment with imatinib may improve outcomes."

"Latar belakang: Karsinoma sel hati (KSH) merupakan jenis keganasan primer hatitersering dengan gambaran histologik menunjukkan diferensiasi sel hepatoselular. Selaininsiden yang tinggi, beban yang berat dari keganasan ini adalah prognosis yang sangatburuk dengan angka rekurensi yang tinggi. Terdapat banyak faktor resiko secaraklinikopatologik yang telah diketahui mempengaruhi prognosis KSH, seperti kadar alfafetoprotein, derajat diferensiasi, dan invasi mikrovaskular. Secara molekular, mutasi p53dan β-catenin merupakan dua mutasi tersering dalam KSH. β-catenin merupakan proteinmultifungsi yang dikode oleh gen CTNNB1 yang dapat ditemukan pada 3 kompartemensel, yaitu di membran sel, sitoplasma dan inti. Jalur Wnt/β-catenin meregulasi prosesseluler yang terkait inisiasi, pertumbuhan, survival, migrasi, diferensiasi, dan apoptosis.Meski sudah banyak diketahui beberapa jalur patofisiologi molekularhepatokarsinogenesis, hubungan dengan aplikasi klinik membutuhkan pemahaman lebihmengenai hubungan sifat molekuler dan sifat fenotip tumor, terutama dalam penentuanfaktor prognosis dan pengembangan terapi target. Penelitian ini bertujuan untuk menilaiekspresi β-catenin pada KSH dan hubungannya dengan berbagai faktor prognosis yaituAFP, derajat diferensiasi dan invasi mikrovaskular.Bahan dan cara: Penelitian ini menggunakan desain potong lintang. Sampel terdiri atas35 kasus KSH yang sudah ditegakkan diagnosisnya berdasarkan pemeriksaanhistopatologik dan/atau imunohistokimia di RSCM dari Januari 2013 sampai September2019. Dilakukan pulasan β-catenin dan analisis statistik dengan uji komparatif terhadapberbagai karakteristik klinikopatologik dan faktor resiko berupa AFP, derajat diferensiasidan invasi mikrovaskular.Hasil: Terdapat perbedaan bermakna ekspresi β-catenin terhadap AFP (p=0,037) danderajat diferensiasi (p=0,043) pada KSH. Ekspresi β-catenin pada inti dengan/tanpasitoplasma lebih sering ditemukan pada kasus KSH dengan kadar AFP rendah dan derajatdiferensiasi baik-sedang. Tidak ditemukan perbedaan bermakna ekspresi β-cateninterhadap invasi mikrovaskular pada KSH (p=1,000).Kesimpulan: Terdapat perbedaan bermakna ekspresi β-catenin terhadap AFP dan derajatdiferensiasi pada KSH.

Background: Hepatocellular carcinoma (HCC) is the most common primary livercancer, displaying histologically hepatocellular differentiation. In addition to its highincidence, the disease burden of HCC is due to its poor prognosis with high recurrencerate. Some of the previously known clinicopathologic prognostic factors of HCC includealpha-fetoprotein (AFP) level, tumor grade and microvascular invasion. At molecularlevel, p53 and β-catenin are the two most common driver mutations in HCC that aremutually exclusive. β-catenin is a multifunction protein that is encoded by CTNNB1 gen.It is found in 3 compartments of cells, which are membrane cell, cytoplasm and nucleus.Wnt/ β-catenin pathway regulates cellular process which is related to initiation, growth,survival, migration, differentiation and apoptosis. Although molecular pathogenesispathways of hepatocarcinogenesis are known, clinical application warrants moreunderstanding in terms of molecular characteristic and tumor phenotype, especially indetermining prognosis and target therapy development. This current study aims to analyzethe expression of β-catenin and its association with prognostic factors, such as AFP,tumor grade and microvascular invasion.Material and method: A cross-sectional study was conducted comprising 35 samples ofsurgically resected HCCs between January 2013 to September 2019 in CiptoMangunkusumo General Hospital. The cases were diagnosed based on histopathologicaland immunohistochemical findings and was then performed β-catenin staining. β-cateninexpression was analyzed with statistical tests to determine expression difference betweenAFP level, tumor grade and microvascular invasion.Result: There were statistically significant difference of β-catenin expression in AFPlevel and tumor grade (p=0.037 and 0.043, respectively). Nuclear with/withoutcytoplasmic expression of β-catenin was more frequently found in HCC with low AFPlevel and well-to-moderately differentiated tumors. No significant difference wasobserved in β-catenin expression between HCC with and without microvascular invasion(p=1.000).Conclusion: β-catenin expression was significantly different in AFP level and tumorgrade."

"ABSTRAK Perawat spesialis neurosains berperan dalam praktik keperawatan berupa pemberi asuhan keperawatan lanjut, melakukan pembuktian ilmiah dan agen pembaharu. Asuhan keperawatan dilakukan pada kasus pasien dengan Tumor Otak dan 30 pasien gangguan neurologis dengan pendekatan Model adaptasi Roy. Perilaku maladaptif paling banyak terganggu pada mode fisologis dengan diagnosa resiko ketidakefektifan perfusi jaringan serebral. Evidence Based Nursing dilakukan dengan menerapkan thermal tactile stimulation pada 3 pasien stroke yang mengalami disfagia dengan hasil yang signifikan p value 0,038 . Program inovasi menerapkan enam screening tools yaitu Insomnia Severity Index ISI , National Institute Health Stroke Scale NIHSS , 3 Incontinence Question 3 IQ , Berg Balance Scale BBS , Frenchay Aphasia Screening Test FAST dan Adult Non Verbal Pain Scale ANVPS pada pasien dengan gangguan neurologi yang terbukti memudahkan perawat dalam menegakkan diagnosa keperawatan yang tepat. Model Adaptasi Roy telah berpengaruh besar terhadap profesi keperawatan. Model ini adalah salah satu model yang paling banyak digunakan dalam memandu penelitian, pendidikan dan praktik keperawatan ABSTRACT Neuroscience nurse specialist play role in nursing practice as advanced nursing care providers, conduct scientific evidence and innovator. Roy adaptation model approach was used in the nursing care of the tumor brain patients and 30 patients of neurological disorders cases. Risk of cerebral tissue perfusion ineffectiveness was the most often of nursing diagnosis enforced which was caused maladaptive behavior in physiological mode. Evidence based nursing was implemented by thermal tactile stimulationin 3 stroke patients with disfagia with significant results p value 0.038 . The Innovation program application six screening tools are Insomnia Severity Index ISI , National Institute of Health Stroke Scale NIHSS , 3 Incontinence Questions 3 IQs , Berg Balance Scale BBS , Frenchay Aphasia Screening Test FAST and Adult Non Verbal Pain Scale ANVPS in neurological disorders patients proven to facilitate nurses in establishing nursing diagnoses. Roy Adaptation Model has greatly influenced the profession of nursing. It is one of the most frequently used models to guide nursing research, education and practice"
