Trichoepithelioma. so named by Jarisch(1894), is a rare benign neoplasm of the skin on face and eyelid. The solitary type which is the most usual form seen in the eyelid occurs mainly in adult, on the other hand multiple type begin to appear at adolescence or puberty as a dominantly inherited condition. A 21 year-old korean female was found to have trichoepithelioma in her left lower eyelid mangm.

Gastric cancer (GC) is the second leading cause of cancer mortality and the fourth most commonly diagnosed malignant diseases. While continued efforts have been focused on GC treatment, the introduction of trastuzumab marked the beginning of a new era of target-specific treatments. Considering the diversity of mutations in GC, satisfactory results obtained from various target-specific therapies were expected, yet most of them were unsuccessful in controlled clinical trials. There are several possible reasons underlying the failures, including the absence of patient selection depending on validated predictive biomarkers, the inappropriate combination of drugs, and tumor heterogeneity. In contrast to targeted agents, immuno-oncologic agents are designed to regulate and boost immunity, are not target-specific, and may overcome tumor heterogeneity. With the successful establishment of predictive biomarkers, including Epstein-Barr virus pattern, microsatellite instability status, and programmed death-ligand 1 (PD-L1) expression, as well as ideal combination regimens, a new frontier in the immuno-oncology of GC treatment is on the horizon. Since the field of immuno-oncology has witnessed innovative, practice-changing successes in other cancer types, several trials on GC are ongoing. Among immuno-oncologic therapies, immune checkpoint inhibitors are the mainstay of clinical trials performed on GC. In this article, we review target-specific agents currently used in clinics or are undergoing clinical trials, and highlight the future clinical application of immuno-oncologic agents in inoperable GC.

The radial artery as a graft for myocardial revascularization was introduced by Carpentier et al. in the early 1970s. Mid-term results were unfortunately discouraging, and the clinical experience with this graft was interrupted. At the end of the 1980s, these authors reproposed the same arterial conduit with more satisfying results, because of improved technique and pharmacological management of the graft. Between October 1994 and July 1995, 36 patients underwent myocardial revascularization with a radial artery graft in Sejong General Hospital. Left internal mammary artery was concomitantly used as a pedicled graft in 34 patients. Fifteen patients(42%) had a complete arterial graft revascularization. A total of 123 distal anastomoses were performed(average 3.4 per patient), including 36 left internal mammary artery grafts(two sequential in 2 patients), and 23 saphenous vein grafts. The remaining 64 distal anastomoses were performed with radial artery grafts (mean 1.8 per patient). The radial arteries were anastomosed to the circumflex(n=38), diagonal( n=18), right coronary(n=6), and left anterior descending coronary artery(n=2). The percentage of radial artery graft anastomoses(64) to the total anastomoses(123) was 52%. The radial artery was used as a single graft in 10 patients, as a sequential graft in 25 patients, and two grafts in 1 patient. Twenty patients underwent associated procedures : coronary endarterectomy(14), coronary artery patch angioplasty(4), mitral valve repair(1), and repair of ventricular septal rupture(1). One patient died of low cardiac output syndrome and the others had no perioperative myocardial infarction. There are no ischemic and functional complications in the arm or hand after removal of the radial artery. Only 1 patient required reexploration of the arm, for the hematoma evacuation, and 2 patients complained transient thumb dysesthesia of the side of the havested arm. This dysesthesia improved within one month. Postoperative angiographic controls were obtained in 11 patients(31%) postoperative 79 to 210 days(mean 126 days). The patency rate were as follows : left internal mammary artery(100%), saphenous vein(100%), and radial artery(95%). We concluded that the radial artery is useful alternative graft, but long term clinical and angiographic studies are required to dertermine whether wider application is warranted.

A 47-year-old woman was referred for surgical treatment of osteomyelitis of the mandible. She had already undergone three previous surgeries. Pre-anesthetic airway evaluation predicted a difficult airway, due to the thin, retro-positioned mandible, tongue, and atrophic changes in the lips and soft tissue. We inserted packing gauzes in the buccal mucosa for easier mask fitting and ventilation. During direct laryngoscopic intubation with a nasotracheal tube (NTT), fracture of a thin mandible can easily occur. Therefore, we used a fiberoptic bronchoscope to insert the NTT. After surgery, we performed a tongue-tie to protect against airway obstruction caused by the backward movement of the tongue during recovery. The patient recovered without any complications. We determined the status of the patient precisely and consequently performed thorough preparations for the surgery, allowing the patient to be anesthetized safely and recover after surgery. Careful assessment of the patient and airway prior to surgery is necessary.

Patients with cleft lip and palate (CLP) must undergo corrective surgeries during infancy and early childhood. Many patients with CLP undergo orthognathic surgery during their childhood for correction of skeletal asymmetries or pharyngoplasty with a pharyngeal flap to improve the quality of speech and velopharyngeal function. During orthognathic surgeries, nasotracheal intubation is performed under general anesthesia. In our case report, the patient had undergone palatoplasty and pharygoplasty previously. During the orthognathic surgery, a flexible fiberoptic bronchoscope-guided nasotracheal tube was inserted through the pharyngeal flap ostium; however, active bleeding occurred in the nasopharynx. Bleeding occurred because the flap was torn. After achieving hemostasis, the surgery was completed successfully. Thus, if a patient may show the potential for velopharyngeal port obstruction, nasotracheal intubation should be performed with utmost care.

PURPOSE: As the number of elderly patients diagnosed with non-small cell lung carcinoma (NSCLC) increases, the number of these patients receiving chemotherapy also increases. However, limited data exists regarding the use of chemotherapy in advanced NSCLC patients who are 75 years of age or older. MATERIALS AND METHODS: Between May 2002 and October 2008, data for 48 advanced NSCLC patients who were 75 years of age or older who had been treated with chemotherapy were retrospectively analyzed. RESULTS: The median age of study participants at the time of first line chemotherapy was 76 years (range, 75 to 87 years) and their median Charlson comorbidity index was 2 (range, 1 to 4). Of the total 48 patients, 43 patients (90%) were treated by platinum-based doublet as a first line chemotherapy regimen. Median progression free survival for first line chemotherapy was 5.7 months (95% confidence interval [CI], 4.93 to 6.47 months) with an overall response rate of 33.3%. After first line chemotherapy, only 14 of the 48 patients (29.2%) received second line chemotherapy. The median overall survival (OS) for these patients was 8.2 months (95% CI, 4.44 to 11.96 months). Multivariate analysis results indicated that female gender and having received second-line or more chemotherapy were independent prognostic factors for increased OS for all 48 patients. Charlson Index was not a significant independent prognostic factor for survival. There were 9 treatment related deaths due to infectious causes (18.8%). CONCLUSION: Patients 75 years of age or older with advanced NSCLC may obtain clinical benefit from the administration of platinum-based doublet or single agent chemotherapy. However, oncologists must consider the aspect of safety in relation to the clinical benefits when managing this patient group.

Background/Aims: Patients with pancreatic cancer (PC) generally have poor clinical outcomes. Early determination of their prognosis is crucial for developing a therapeutic strategy. Recently, various inflammatory markers have been validated as prognostic indicators for many cancers, including PC. However, few studies have evaluated these markers together. Thus, the purpose of this study was to comprehensively evaluate the value of inflammatory markers as prognostic indicators in patients with advanced PC treated with gemcitabine-based chemotherapy as the first line regimen. Methods: This was a single-center retrospective study evaluating 302 patients with advanced PC who began first line treatment between November 2004 and August 2016. These patients were monitored until June 2017. Survival rates were assessed with univariate and multivariate analyses. Continuous variables were separated using the normal range or ideal cut-off levels determined by receiver operating curve analyses. Results: Among inflammatory markers evaluated, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and C-reactive protein (CRP) to albumin ratio (CRP-albumin ratio) were independent predictors of overall survival (hazard ratio, 1.712, 1.345, and 1.454, respectively). Difference in survival rates was significant (p < 0.001) among three groups divided by the number of marker-related risks. Conclusions Baseline inflammatory markers including NLR, PLR, and CRP-albumin ratio are useful in predicting survival rates in patients with PC. Combining these three markers is proven to be valuable.

PURPOSE: The purpose of this study was to determine the efficacy and safety of treatment using gemcitabine and capecitabine for patients with advanced pancreatic cancer. MATERIALS AND METHODS: Patients with advanced unresectable pancreatic adenocarcinoma were enrolled in the study. Inclusion criteria included no prior systemic chemotherapy or radiation therapy, at least one radiographically documented and measurable tumor lesion, and adequate patient organ functions. The patients received 1,000 mg/m2 gemcitabine intravenously on days 1, 8 and 15, and 830 mg/m2 of oral capecitabine twice a day on days 1-21 of a 28-day cycle. RESULTS: Fifty patients with a median age of 53 years (range, 39 to 76 years) were enrolled in the study. The median follow-up was 10.0 months. The objective response rate of the 50 patients was 48.0% (95% CI, 22.5 to 57.1%). The median time to progression and overall survival were 6.5 months (95% CI, 2.3 to 8.7 months) and 10.0 months (95% CI, 5.7 to 16.7 months), respectively. Grade 3-4 toxicities associated with chemotherapy included neutropenia (22%), anemia (8%), thrombocytopenia (6%), and hand-foot syndrome (10%). CONCLUSION: Combination chemotherapy using gemcitabine and capecitabine was well tolerated and demonstrated promising efficacy in the treatment of advanced pancreatic cancer.

BACKGROUND: Surgery for Stanford type A aortic dissection shows a high operative mortality rate and frequent postoperative brain injury. This study was designed to find out the risk factors leading to operative mortality and brain injury after surgical repair in patients with type A aortic dissection. MATERIAL AND METHOD: One hundred and eleven patients with type A aortic dissection who underwent surgical repair between February, 1995 and January, 2005 were reviewed retrospectively. There were 99 acute dissections and 12 chronic dissections. Univariate and multivariate analysis were performed to identify risk factors of operative mortality and brain injury. RESULT: Hospital mortality occurred in 6 patients (5.4%). Permanent neurologic deficit occurred in 8 patients (7.2%) and transient neurologic deficit in 4 (3.6%). Overall 1, 5, 7 year survival rate was 94.4, 86.3, and 81.5%, respectively. Univariate analysis revealed 4 risk factors to be statistically significant as predictors of mortality: previous chronic type III dissection, emergency operation, intimal tear in aortic arch, and deep hypothemic circulatory arrest (DHCA) for more than 45 minutes. Multivariate analysis revealed previous chronic type III aortic dissection (odds ratio (OR) 52.2), and DHCA for more than 45 minutes (OR 12.6) as risk factors of operative mortality. Pathological obesity (OR 12.9) and total arch replacement (OR 8.5) were statistically significant risk factors of brain injury in multivariate analysis. CONCLUSION: The result of surgical repair for Stanford type A aortic dissection was good when we took into account the mortality rate, the incidence of neurologic injury, and the long-term survival rate. Surgery of type A aortic dissection in patients with a history of chronic type III dissection may increase the risk of operative mortality. Special care should be taken and efforts to reduce the hypothermic circulatory arrest time should always be kept in mind. Surgeons who are planning to operate on patients with pathological obesity, or total arch replacement should be seriously consider for there is a higher risk of brain injury.
