Background: Lymphadenopathy is a common presentation in both benign and malignant diseases which need to be diagnosed without delay. Fine needle aspiration cytology (FNAC) helps us diagnose a disease and follow its course, including the response to therapy. Aim: This study aimed to analyze the clinicopathological features of metastatic lymphadenopathy and the diagnostic utility of FNAC in our setting. Materials and Methods: This two-year prospective study included all the patients with metastatic lymphadenopathy, diagnosed with FNAC. Results: A total of 412 cases (male:female ratio, 1.3:1; age range, 3 to 90 years) were studied. Supraclavicular lymph nodes were involved most commonly (50.5%). The commonest metastatic tumor was squamous cell carcinoma in general (30.1%) and in males (37.6%), and infiltrating ductal carcinoma (25.3%) in females. Lung, with 64 (15.5%) cases followed by esophagus, 60 (14.6%) cases; breast, 49 (11.9%) cases; skin, 32 (7.8%) cases; and stomach, 25 (6.1%) cases were the most common primary sites of malignancy. In 69 patients, excision biopsy was performed. Histopathological findings correlated well with that of cytology in all these cases. Conclusions: FNAC is an important tool in the diagnostic work up of metastatic lymphadenopathy, which in the hands of an experienced and skilful cytopathologist can avoid the need for excision biopsy.

Aim: To evaluate the predominant colorectal polyps in the Almadinah region of Saudi Arabia. Materials and Methods: In this iretrospective study, we analyzed pathology reports of colonoscopies performed in King Fahad Hospital, Madinah, Saudi Arabia during the period 2006 to 2013. Data based on patient age, gender, size, site and type of polyps and the degree of dysplasia were analyzed by software SPSS 17 and compared with other published studies from different geographic regions of the world. Results: During these years, 224 patients had colonic polyps, of whom 149 (66.5%) were men and 75 (33.5%) were women. The most common types of polyps were adenomatous (166), followed by hyperplastic polyps (24), juvenile (18), inflammatory (13), lipomatous (2) and one patient with Peutz-Jegher polyps. Tubulovillous adenoma was the commonest adenomatous polyp (102), followed by tubular (41) and villous (23) types. The sigmoid colon was the most commonly involved region (36.6%). Dysplasia was significantly associated with female patients who had large size tubulovillous polyps located in the left colon. Conclusions: The type and distribution of colorectal polyps in Saudi Arabia is very similar to Western countries. Patient gender, and size, histological type and location of polyps are closely related to dysplastic change in colonic polyps.

Purpose: This study evaluated the effect of an Educational Program on Palliative Care for MPM for Nurses in Japan. Program: The 5-h program consisted of lectures and care planning group work. Materials and Methods: This study used a pretest-posttest design with a single cohort of nurses and included a Difficulties in Palliative Care for Patients with MPM (DPCMPM) Scale with 15 items. The pre- and posttest scores were compared using a t-test. Results: We included 27 female nurses with a mean of 14.4 years of nursing experience. In 12 of 15 DPCMPM items, the posttest difficulty scores were lower than the pretest scores. Participants highly evaluated the program for validity, clarity, clinical usefulness, and the facilitators. The Palliative Care for MPM Handbook for Nurses was developed as an educational tool for clinical settings. Conclusions: The Educational Program on Palliative Care for MPM for Nurses was effective in reducing nursing difficulties.
Background: In this study prognostic correlations of histopathologic parameters and the Ki-67 proliferation index and as well as the diagnostic value of immunohistochemical markers in pheochromocytomas were evaluated. Materials and Methods: A total of 22 patients diagnosed with a pheochromocytoma between 2000-2010 in Izmir Katip Celebi University Ataturk Training and Research Hospital were included. Diagnostic value of the PASS scoring system, and prognostic correlations of histopathologic parameters and Ki-67 proliferation index were investigated. SPSS for Windows 17.0 software was used for statistical analysis. Results: There was no statistically significant correlation between recurrence and clinicopathologic parameters or the PASS score (PASS>4). In addition, there were no statistically significant correlations between PASS score and clinicopathologic parameters, such as diameter (5 cm), weight (>100g), gender (female/male ratio) and age (25-45/45-55/>55). Besides, there were no significant correlation between diameter and clinicopathological parameters and also recurrence. However, there was a statistically significant correlation between Ki-67 proliferation index and capsule invasion (p=0.047). Conclusions: Some but not most of the findings in our study were concordant with the literature. To clarify relationships, investigations with standard scoring systems which are not affected by subjective factors and feature appropriate histopathological criteria should be made on larger study groups.
Background: The complex anatomy of the pancreaticobiliary duct was crucial in management of pancreatic and biliary tract disease. Materials and Methods: Fresh specimens of pancreas, common bile duct (CBD), and duodenum were obtained en bloc from autopsies of 160 patients. Results: Ninety-three male and 67 female patients were included. The length of the pancreas ranged from 9.8-20 cm (mean, 16.20 +/- 1.70 cm). The intrapancreatic portion of the CBD showed patterns of three types: most common (85.30%) was type A, in which the anterior surface of the common bile duct was totally covered, while its posterior surface was partially covered, by the pancreatic parenchyma. On dissection of the accessory duct of Santorini, the accessory duct was traceable to the duodenal wall in 67.6%. The anatomy of the Wirsung-choledochus confluence was grouped into five different types. The common channel was found in 75.60% and its length varied from just a common junction (so-called "V-type" anatomy) to 15 mm (Y-type-b). Separate papillae (so-called "II-type") were found in 15.3% of specimens. Conclusions: Several important points regarding the anatomy of the pancreaticobiliary junction and pancreatic ductal system were illustrated in this study.
Purpose: Laparoscopic wedge resection of gastric submucosal tumor may be difficult in case of the endophytic mass or the mass located unreachable area such as cardia, and intragastric approach can be useful. We would present the experiences of the intragastric wedge resection. Materials and Methods: There were 7 patients diagnosed as gastric submucosal tumor and underwent the intragastric wedge resection at Surgery, Chungnam National University Hospital. We reviewed medical record. Results: There were 3 male and 4 female. Mean age was 65 years-old (57~73). Mean body mass index was 26.28 kg/$m^2$ (21.28~35.30). Location of lesions was 4 cardia, 2 fundus and 1 midbody, respectively. Mean operation time was 83.6 minutes (70~105). All patients were healed without any complication. Mean postoperative hospital stay was 5.4 days (4~6). Mean size was 2.7 cm (2.3~3.8). Pathologic finding was 5 gastrointestinal stromal tumor and 2 leiomyoma. Conclusions: The single incision intragastric wedge resection of gastric submucosal tumor is feasible and acceptable, especially in mass of gastric upper part.
In the present study, iodine-131 S values (rT ← thyroid) were calculated for 30 target organs and tissues using the most recently developed Korean reference computational phantoms. The calculated S values were then compared with those of the International Commission on Radiological Protection (ICRP) reference computational phantoms to investigate the dosimetric impact of the Korean S values against those of the ICRP reference phantoms. The results showed significant differences in the S values due to the different anatomical/morphological characteristics between the Korean and ICRP reference phantoms. Most target organs/tissues showed that the S values of the Korean reference phantoms are lower than those of the ICRP reference phantoms, by up to about 4 times (male spleen and female thymus). Exceptionally, three target organs/tissues (gonads, thyroid, and extrathoracic region) showed that the S values of the Korean reference phantoms are greater, by 1.5-3.7 times. We expect that the S values calculated in the present study will be beneficially used to estimate organ/tissue doses of Korean patients under radioiodine therapy.
Background: Mutations in the tyrosine kinase domain of the epidermal growth factor receptor (EGFR) in non-small cell lung cancer (NSCLC) are predictive of response to EGFR-targeted therapy in advanced stages of disease. This study aimed to determine the frequency of EGFR mutations in NSCLCs and to correlate their presence with clinical characteristics in multiethnic Malaysian patients. Materials and Methods: In this prospective study, EGFR mutations in exons 18, 19, 20 and 21 in formalin-fixed paraffin-embedded biopsy specimens of consecutive NSCLC patients were asessed by real-time polymerase chain reaction. Results: EGFR mutations were detected in NSCLCs from 55 (36.4%) of a total of 151 patients, being significantly more common in females (62.5%) than in males (17.2%) [odds ratio (OR), 8.00; 95% confidence interval (CI), 3.77-16.98; p<0.001] and in never smokers (62.5%) than in ever smokers (12.7%) (OR, 11.50; 95%CI, 5.08-26.03; p<0.001). Mutations were more common in adenocarcinoma (39.4%) compared to non-adenocarcinoma NSCLCs (15.8%) (p=0.072). The mutation rates in patients of different ethnicities were not significantly different (p=0.08). Never smoking status was the only clinical feature that independently predicted the presence of EGFR mutations (adjusted OR, 5.94; 95%CI, 1.94-18.17; p=0.002). Conclusions: In Malaysian patients with NSCLC, the EGFR mutation rate was similar to that in other Asian populations. EGFR mutations were significantly more common in female patients and in never smokers. Never smoking status was the only independent predictor for the presence of EGFR mutations.

Background: Pancreatic cancer has a high mortality rate because it is usually diagnosed late. Since little is known about this cancer in Iran, with the aim of improving this knowledge deficiency, we evaluated clinical, laboratory biomarkers, imaging findings and treatment modalities in Iranian patients with pancreatic adenocarcinoma. Materials and Methods: 131 cases of pancreatic adenocarcinoma in 2010-2013 were obtained from the Taleghani Hospital Record Department. Cases confirmed by histopathology from CT-guided biopsy, EUS-FNA and surgery examination were included. We excluded those with incomplete medical records. Results: The study included 131 subjects between 24 and 97 years of age and a mean age of $63{\pm}13.4$ years. Eighty (61.1%) were male and 51 (38.9%) female. Previous history included diabetes mellitus in 36 (27.5%), alcohol drinking in 5 (3.9%), smoker in 28 (21.4%) and opium addiction in 13 (10%). The common presenting history included weight loss in 79 (60.3%), abdominal pain in 77 (58.8%), fever in 11 (8.4%), nausea in 30 (22.9%), jaundice in 72 (55%), pruritus in 52 (39.7) and anemia in 33 (25.2%). CA19-9 levels with cut offs of 50, 100 and 200 U/ml were increased in 81%, 72% and 66% of patients, respectively. Tumor staging was: stage I, 3 (2.3%); stage II, 10 (7.6%); stage III, 58 (44.3%); and stage IV, 60 (45.8%). From 45 patients, 17 received ERCP inserted metallic stents and 22 plastic stents, the remaining 6 failed that PTC was done. Whipple surgery and chemotherapy were conducted for 10 and 29 patients, respectively. Conclusions: This disease affected older people and there was a male preponderance. The commonest risk factors were diabetes mellitus, smoking and cholelithiasis. The majority of patients presented with loss of appetite, loss of weight, jaundice, abdominal pain and discomfort. Almost all presented at late stages of the disease so that curative surgery was impossible. Also chemotherapy was only performed in a few patients as a neoadjuant treatment.

To analyze biochemical changes of liver function following combined radiotherapy and hyperthermia, we reviewed retrospectively 37 patients with hepatocellular carcinoma treated with radiotherapy and hyperthermia between July 1988 and December 1990 at Department of Radiation Oncology, Yonsei University College of Medicine. Mean age was 52.7 years and male to female ratio was 11:1. The patients were classified as follows; to A and B group by Child's classification, to M and L group by irradiated volume, and subclassified into BM, BL, AM and AL group according to the combination of Child's classification and irradiated volume. Radiation dose to the primary tumor was 3060 cGy with daily 180 cGy, 5 fraction per week using 10 MV or 4 MV linear accelerator. Hyperthermia (Thermotron RF-8) was performed more than 4 times in all patients. Biochemical parameters including albumin (Alb), total bilirubin (T. Bil), aspartate aminotransferase (AST or SGOT), alanine aminotransferase (ALT or SGPT), and alkaline phosphatase (ALP) were regularly followed from 1 week before the treatment to 3 months after the treatment. The results are summerized as follows; 1) In all the patient, mean ALP level peaked at 1 month, decreased at 2 months, slightly increased at 3 months after the treatment. Mean SGOT and SGPT levels peaked at 1 month after the treatment. Mean T. Bil level increased continuously and highest at 3 months after the treatment. Mean Alb level did not show significant changes.; 2) Mean ALP level retured to normal level at 3 month after the treatment in A but increased in B group and the differences were statistically significant (p<0.01). Mean SGOT and SGPT levels peaked 1 month in A and 2 months after the treatment in B group. All the biochemical parameters did not show significant difference between M and L group. Mean ALP level increased at 3 months after the treatment in BM and BL groups and decreased in AM and AL groups. Mean SGOT level increased at 3 months after the treatment in BL groups.; 3) Hepatic failure occurred within 3 months after the treatment in 4 patients, all of whom were in BL group. It is suggested that pre-treatment liver function and irradiated volume influence biochemical changes of liver in patients with hepatocellular carcinoma following combined radiotherapy and hyperthermia, and this treatment modality appears generally to be safe but might cause hepatic failure particularly in patient with poor liver function and large treatment volume.
