"Berdasarkan pengalaman Departemen Bedah Saraf Fakultas Kedokteran Universitas Indonesia – Rumah Sakit Cipto Mangunkusumo (FKUI-RSCM), pasien datang berobat dengan durasi keluhan yang beragam untuk suatu diagnosis adenoma hipofisis. Sebagai rumah sakit pusat rujukan nasional, semua pasien adenoma hipofisis yang datang ke institusi kami merupakan pasien rujukan dari dokter spesialis mata, spesialis saraf, maupun dokter spesialis bedah saraf dari institusi lain. Adenoma hipofisis dapat menyebabkan keluhan visus, lapang pandang, dan keluhan-keluhan lain yang diakibatkan oleh gangguan hormonal. Beberapa penelitian telah menyatakan hubungan antara durasi keluhan dengan luaran klinis dengan hasil yang signifikan. Pada penelitian ini akan dicari hubungan antara durasi, yang dihitung mulai dari awal keluhan sampai dilakukan tindakan operasi, dengan luaran visus dan lapang pandang pada pasien adenoma hipofisis yang dilakukan operasi dengan pendekatan transnasal transfenoid. Penelitian ini merupakan penelitian restrospektif pada pasien adenoma hipofisis yang dilakukan tindakan operasi dengan pendekatan transnasal transfenoid antara tahun 2015-2017. Seluruh operasi dilakukan oleh spesialis bedah saraf di RSCM. Semua pasien pada penelitian ini mengalami penurunan visus dan penyempitan lapang pandang. Durasi antara onset sampai dengan dilakukan tindakan operasi dihitung dalam satuan bulan. Dilakukan pemeriksaan visus dan lapang pandang 1 hari sebelum operasi dan dalam 1 sampai 2 bulan pasca operasi. Penelitian ini juga menghitung volume tumor, presentase tumor yang diambil, dan perluasan tumor, tetapi tidak dapat dilakukan uji statistik karena dibutuhkan jumlah sampel yang lebih banyak. Tujuh puluh satu pasien dengan keluhan penurunan visus dan penyempitan lapang pandang dengan median usia 42 tahun (20-77 tahun). Terdapat 36 pasien berjenis kelamin laki-laki dan 35 pasien perempuan. Median durasi mulai dari onset sampai dilakukan tindakan operasi untuk keluhan penurunan visus dan penyempitan lapang pandang adalah sama yaitu 12 bulan (1-108 bulan). Tedapat perbaikan visus pasca operasi pada 50 pasien (40,5%), dengan median durasi onset sampai dilakukan tindakan operasi adalah 11 bulan (p=0,58). Pada pasien keluhan penyempitan lapang pandang didapatkan perbaikan klinis pada 48 pasien (67.6%), dengan median durasi onset sampai dilakukan tindakan adalah 12 bulan (p=0.01). Dari penelitian ini dapat ditarik kesimpulan bahwa terdapat hubungan bermakna secara statistik antara durasi onset sampai dilakukan tindakan operasi dengan luaran klinis lapang pandang. Perbaikan lapang pandang didapatkan pada pasien yang memiliki durasi onset sampai dilakukan tindakan operasi sampai dengan 12 bulan.

Based on the experience of the Department of Neurosurgery, Faculty of Medicine, Universitas Indonesia-Cipto Mangunkusumo Hospital (FMUI-Cipto Mangunkusumo Hospital), patients came seeking treatment with varying duration of complaints for a diagnosis of pituitary adenoma. As a national referral center hospital, all pituitary adenoma patients who came to our institution were referred from ophthalmologists, neurologists, and neurosurgeons from other institutions. Pituitary adenomas can cause decrease of visual acuity (VA), narrowing visual field (VF), and other complaints caused by hormonal disorders.¹ Several studies have showed that the duration of complaints were related significantly with clinical outcomes.^2,3,4,5,6

In this study, we investigated the relationship between duration, which is calculated from the time of symptoms first appeared to the time of surgery, and outcome (visual field and visual acuity) in pituitary adenoma patients who underwent surgery via transnasal-transsphenoidal approach.

This study used retrospective design on pituitary adenoma patients who was performed surgery via transnasal-transsphenoidal approach between 2015-2017. All surgeries were performed by neurosurgeons at RSCM. All patients in this study experienced decreased VA and narrowing of the VF. The duration between symptoms’ onset and surgery was calculated in months. VA and VF examinations were performed 1 day before surgery and within 1 to 2 months postoperatively. This study also calculated the volume of tumor, the percentage of tumor removal, and the extent of tumor, but statistical tests cannot be carried out on these parameters because more samples are needed.

There were 71 patients with decreased visual acuity and narrowed visual field, consisted of 36 male and 35 female patients, with a median age of 42 years (20-77 years). The median length of duration of onset for both symptoms is the same, which was 12 months (1-108 months).

Fifty patients (40.5%) had improved VA postoperatively, with median duration of onset was 11 months (p = 0.58). Clinical improvement in VF was experienced in 48 patients (67.6%), in which the median duration of onset was 12 months (p = 0.01)

There was a statistically significant relationship between the duration of onset and the VF outcomes. Improvements in the VF were found in patients who underwent surgery up to 12 months after the time of onset."

"Pleomorphic parotid gland adenomas (PPA's) have a variability of histopathologic appearances making it difficult to classify and its biological behavior is also difficult to predict. To find a better understanding of this phenomenon a retrospective causal study was undertaken on 25 benign and 17 malignant PPA's cases. Having exposed the underlying process it is hoped that it can be applied for the prediction of the malignant changes occur in PPA's depending on the expressions of oncogenes rasP-21, C-erbB-2 and P-53 immunohistochemically. The immunoexpression were defined by the criteria: 0=negative; +1=focal (<20%); +2=heterogenous (20-50%); and +3=diffuse (>50%). heterogenous and diffuse are considered to be an overexpression criterias. The immunoexpression percentage of ras P-21 (88.1%), C-erbB-2 (92.8%) and P-53 (97.6%) is highly significant (p<0.01) in emerging the variability of the biological behaviour of PPA's. The sensitivity of immunohistochemistry and Pvnegative (both 100%) are indicative of their abilities for detecting the malignant potentials of PPA's. The spesifisity of immunohistochemistry of 50% and the presence of false positive in the benign PPA's cases could be considered of having the potentials for malignant change. Apparently overexpression of the rasP-21, C-erbB-2 and P-53 plays a role as a dependable indicator of having the potentials of benign PPA's for malignant change."

Pituitary adenoma is one of the most common primary intracranial tumor that some can behave aggresively with higher reccurrence/regrowth risk and have bad impact to patient’s quality of life. Early identification of aggressive pituitary adenoma can help for deciding aggressive treatment strategies and strict follow-up to prevent recurrence/regrowth. Proliferation assesment using Ki-67 expression is expected to be one of the predictor of tumor recurrence/regrowth. This study aims to evaluate Ki-67 expression in pituitary adenoma with recurrence/regrowth and without recurrence/regrowth. This is an analytic retrospective study with cross sectional study design including specimens diagnosed as pituitary adenoma recorded in archives of Anatomical Pathology Departement FMUI/CMH from 2016-2020. Ki-67 immunostaining was conducted and Ki-67 expression in percentage was evaluated. Data was analyzed statistically to evaluate Ki-67 expression. Cut-off point to predict recurrence/regrowth was determined using receiving operator charasteristic curve analysis. Forty-six cases were selected, consisted of 23 cases with recurrence/regrowth and 23 cases without recurrence/regrowth. There was higher expression of Ki-67 in adenoma with recurrence/regrowth than adenoma without recurrence/regrowth (1,58% vs 0,88%, p=0,03). Recommended cut off value to predict recurrence/regrowth in this study was 1,37%. Higher Ki-67 expression was associated with recurrence/regrowth in pituitary adenoma."

ABSTRACTColorectal cancer CRC is considered as major health problem, one type of cancer that most often occurs as well as the second largest cause of death in western countries and in Indonesia. Serrated colorectal adenocarcinoma SA is one type of CRC. One of colorectal carcinogenesis pathway is serrated pathway that known to involve KRAS gene mutation. Other tumor markers that also involved in the process of its carcinogenesis were P53 and Bcl 2. Histomorphological criteria found by Tuppurainen et al currently used as marker of SA. Limited facilities of molecular pathology laboratory in Indonesia emphasize the needs of making scoring model by using histomorphological features of SA and or P53 and Bcl 2 protein expression to predict KRAS mutation.A cross sectional study conducted to 39 cases of SA registered in Departement of Anatomical Pathology FMUI Ciptomangunkusumo Hospital from 2013 ndash 2015. All clinical data related to the cases were collected. Each case was reevaluated based on Tuppurainen histomorphological criteria, tumor markers Bcl 2 and P53 , and KRAS status. Histomorphological examination is conducted per case and per instance to 100 nodes case.Present study showed that most cases of SA was found in male 51.3 , aged ge 40 years 71.8 , located in left colon 84.6 , did not have metastasis 92.3 , with KRAS mutation status 71.8 . P53 and Bcl 2 protein expressions were found in 69.2 and 51.3 respectively, with no significant association with KRAS status. Histomorphological features of KRAS status found in epithelial serration, nucleus location, nucleus condition, cytoplasm and mucin. Epithelial serration has the highest odds ratio OR 2.7 IK 95 2.30 ndash 3.07 followed by mucin OR 2.0 IK 95 , 1.15 ndash 3.65 . Statistical values showed scoring models consisted of epithelial serrations, nucleus location, nucleus condition and presence of mucin CI 95 between 61 ndash 65 . The sensitivity and specificity cut off point located on the number 16, with sensitivity value was 72 and specificity 48 .Conclusion A scoring system model yielded 16 as cut off score was obtained to predict KRAS mutations based on epithelial serrations, nucleus location, nucleus condition and presence of mucin.Keywords Bcl2, Colorectal cancer, colorectal serrated adenocarcinoma, KRAS mutation, P53, serrated pathway"

"Phleomorphic adenoma is the most commonly found tumor of the salivary glands. This tumor is usually found in the postero-lateral region of the hard palate. In this case, a phleomorphic adenoma tumor situated in the oropharynx region was reported. The CT-Scan results showed an expansive and infiltrative appearance, suspected to be a malignancy, where wide excision was previously planned to be carried out. During surgery, the mass was found pedunculated in the soft palate. It was then decided to perform an excision as the choice of therapy."
