The Additive Impact of Transbronchial Cryobiopsy Using a 1.1-mm Diameter Cryoprobe on Conventional Biopsy for Peripheral Lung Nodules / Journal of the Korean Cancer Association, 대한암학회지

Purpose@#The diagnostic yield of transbronchial biopsy (TBB) using radial probe endobronchial ultrasound (RP-EBUS) is 71%, which is lower than that of transthoracic needle biopsy. We investigated the performance and safety of sequential transbronchial cryobiopsy (TBC) using a novel 1.1-mm diameter cryoprobe, after conventional TBB using RP-EBUS for the diagnosis of peripheral lung lesions (PLLs). @*Materials and Methods@#From April 2021 to November 2021, 110 patients who underwent bronchoscopy using RP-EBUS for the diagnosis of PLL ≤ 30 mm were retrospectively included in our study. All records were followed until June 2022. @*Results@#The overall diagnostic yield of combined TBB and TBC was 79.1%, which was higher than 60.9% of TBB alone (p=0.005). The diagnostic yield of sequential TBC was 65.5%, which increased the overall diagnostic yield by 18.2%. The surface area of tissues by TBC (mean area, 18.5 mm2) was significantly larger than those of TBB by 1.5-mm forceps (3.4 mm2, p < 0.001) and 1.9-mm forceps (3.7 mm2, p=0.011). In the multivariate analysis, PLLs with the longest diameter of ≤ 22 mm were found to be related to additional diagnostic benefits from sequential TBC (odds ratio, 3.51; 95% confidence interval, 1.043 to 11.775; p=0.042). Complications were found in 10.5% of the patients: pneumothorax (1.0%), infection (1.0%), and significant bleeding (8.6%). None of the patients developed any life-threatening complications. @*Conclusion@#Sequential TBC with a 1.1-mm cryoprobe improved the performance of conventional TBB using RP-EBUS without serious complications.

Should We Perform Repeated Re-biopsy for the Detection of T790M Mutation? / Journal of the Korean Cancer Association, 대한암학회지

Purpose@#Epidermal growth factor receptor (EGFR) T790M mutations have been detected in the second or third rebiopsy, even if the T790M mutation was not identified in the first rebiopsy. This meta-analysis investigated the EGFR T790M mutation detection rates and its additional advantages with repeated rebiopsies. @*Materials and Methods@#We searched through the PubMed and EMBASE databases up to June 2022. Studies reporting rebiopsy to identify the EGFR T790M mutation in case of disease progression among patients with advanced non-small cell lung cancer and multiple rebiopsies were included. The quality of the included studies was checked using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool. @*Results@#Eight studies meeting the eligibility criteria, reporting 1,031 EGFR mutation–positive patients were selected. The pooled EGFR T790M mutation detection rate of the first and repeated rebiopsies were 0.442 (95% confidence interval [CI], 0.411 to 0.473; I2=84%; p < 0.01) and 0.465 (95% CI, 0.400 to 0.530; I2=69%; p < 0.01), respectively. Overall, the pooled detection rate of EGFR T790M mutation was 0.545 (95% CI, 0.513 to 0.576), which increased by 10.3% with repeated rebiopsies. @*Conclusion@#This meta-analysis identified that repeated rebiopsy increases the detection rate of EGFR T790M mutation by 10.3%, even if EGFR T790M mutation is not detected in the first rebiopsy. Our results indicate that the spatiotemporal T790M heterogeneity can be overcome with repeated rebiopsy.

Real-world evaluation of atezolizumab and etoposide-carboplatin as a first-line treatment for extensive-stage small cell lung cancer

Background/Aims@#Despite the obvious benefits of adding immune checkpoint inhibitors to platinum-etoposide chemotherapy in patients with extensive-stage small-cell lung cancer (ES-SCLC), real-world data remain scarce. @*Methods@#This retrospective study included 89 patients with ES-SCLC treated with platinum-etoposide chemotherapy alone (chemo-only group; n = 48) or in combination with atezolizumab (atezolizumab group; n = 41) and compared the survival outcomes between these two groups. @*Results@#Overall survival (OS) was significantly longer in the atezolizumab group than in the chemo-only group (15.2 months vs. 8.5 months; p = 0.047), whereas the median progression-free survival was almost the same (5.1 months vs. 5.0 months) in both groups (p = 0.754). Subsequent multivariate analysis revealed that thoracic radiation (hazard ratio [HR], 0.223; 95% confidence interval [CI], 0.092–0.537; p = 0.001) and atezolizumab administration (HR, 0.350; 95% CI, 0.184–0.668; p = 0.001) were favorable prognostic factors for OS. In the thoracic radiation subgroup, patients who received atezolizumab demonstrated favorable survival outcomes and no grade 3–4 adverse events (AEs). @*Conclusions@#The addition of atezolizumab to platinum-etoposide resulted in favorable outcomes in this real-world study. Thoracic radiation was associated with improved OS and acceptable AE risk in combination with immunotherapy in patients with ES-SCLC.

Problems in the Pathologic Diagnosis of Suspected Lung Cancer / 결핵및호흡기질환

Since the introduction of low-dose computed tomography (CT) screening for patients at high risk of lung cancer, the detection rate of suspicious lung cancer has increased. In addition, there have been many advances in therapeutics targeting oncogenic drivers in non-small cell lung cancer. Therefore, accurate pathological diagnosis of lung cancer, including molecular diagnosis, is increasingly important. This review examines the problems in the pathological diagnosis of suspected lung cancer. For successful pathological diagnosis of lung cancer, clinicians should determine the appropriate modality of the diagnostic procedure, considering individual patient characteristics, CT findings, and the possibility of complications. Furthermore, clinicians should make efforts to obtain a sufficient amount of tissue sample using non- or less-invasive procedures for pathological diagnosis and biomarker analysis.

Nationwide Cross-sectional Study of Association between Pterygium and Alkaline Phosphatase in a Population from Korea

PURPOSE: We determined whether elevated serum alkaline phosphatase (ALP) was related to prevalence, location, type, length, and recurrence of pterygium in a population from the Republic of Korea.METHODS: A nationwide cross-sectional dataset, the Korean National Health and Nutrition Examination Survey (2008–2011), was used in this study. All participants were > 30 years of age and underwent the ALP test and ophthalmic evaluation (n = 22,359). One-way analysis of variance, the chi-square test, and Fisher's exact test were used to compare characteristics and outcomes among participants. Multivariable logistic regression was used to examine the possible associations between serum ALP levels and various types of pterygium. Data were adjusted for known risk factors for development of pterygium and ALP elevation (age, sex, residence, sunlight exposure, drinking, smoking, hypertension, diabetes, BMI, AST, ALT, vitamin D, and HDL).RESULTS: The overall prevalence of pterygium was 8.1%, and participants with pterygium had higher levels of serum ALP (p < 0.001). Participants with higher serum ALP had a significantly higher prevalence of all types of pterygium than those in the lower serum ALP quartiles. After adjusting for potential confounding factors, multivariate logistic regression analysis revealed that ALP was associated with the prevalence of pterygium (odds ratio [OR], 1.001; p = 0.038). Trend analysis between the OR and ALP quartiles revealed a linear trend in overall prevalence and in the intermediate type of pterygium. Subgroup analysis revealed a stronger correlation in participants > 50 years of age. One-way analysis of variance revealed an association between the size of pterygium and serum ALP quartile levels. Serum ALP was not associated with recurrence of pterygium.CONCLUSIONS: Increased serum ALP was associated with the prevalence and size of pterygium.

QuantiFERON-TB Gold PLUS versus QuantiFERON- TB Gold In-Tube test for diagnosing tuberculosis infection

Background/Aims@#QuantiFERON-TB Gold PLUS (QFT-PLUS) was developed as a new version of the interferon-γ (IFN-γ) release assay that contains an extra antigen tube to elicit a CD8+ T-cell response in addition to a CD4+ T-cell response. This study aimed to evaluate the performances of QFT-PLUS versus QuantiFERON-TB Gold In-Tube (QFT-GIT) for detecting tuberculosis (TB) infection. @*Methods@#Between October, 2016 and May, 2018, 137 participants were prospectively recruited and subjected to QFT-GIT and QFT-PLUS testing. The concordance between tests and performance based on different immune states and/or TB infection risk were evaluated. @*Results@#The 137 participants were classified as follows: active TB (n = 14), TB contact (n = 14), screening before biologic therapy (n = 85) and other disease (n = 24). The positive results for either test were 100% (n = 14/14), 42.9% (n = 6/14), 15.3% (n = 13/85), and 62.5% (n = 15/24) in each four groups, respectively. The QFT-GIT and QFT-PLUS test results showed good concordance with 91.2% agreement and a Cohen’s κ of 0.807. The good concordance between two tests was also observed in 64 immunocompromised subjects (agreement of 90.6% and a Cohen’s κ of 0.711). The intra-class correlation coefficient for each antigen tube of the QFT-PLUS showed a good correlation with the IFN-γ release of the QFT-GIT (TB1 = 0.912, p < 0.001; TB2 = 0.918, p < 0.001). @*Conclusions@#QFT-PLUS showed highly comparable results to those of QFT-GIT for diagnosing TB infection in South Korea as well as in immunocompromised subjects.

Utility of Computed Tomography in a Differential Diagnosis for the Patients with an Initial Diagnosis of Chronic Obstructive Pulmonary Disease Exacerbation / 결핵

BACKGROUND: The utility of computed tomography (CT) in the differential diagnosis of patients with chronic obstructive pulmonary disease (COPD) exacerbation remains uncertain. However, due to the low cost associated with CT scan along with the impact of Koreas' health insurance system, there has been a rise in the number of CT scans in the patients with initial diagnosis of COPD exacerbations. Therefore, the utility of CT in the differential diagnosis was investigated to determine whether performing CT scans affect the clinical outcomes of the patients with an initial diagnosis of COPD exacerbation. METHODS: This study involved 202 COPD patients hospitalized with an initial diagnosis of COPD exacerbation. We evaluated the change in diagnosis or treatment after performing a CT scan, and compared the clinical outcomes of patient groups with vs. without performing CT (non-CT group vs. CT group). RESULTS: After performing CT, the diagnosis was changed for two (3.0%) while additional diagnoses were made for 27 of the 64 patients (42.1%). However, the treatment changed for only one (1.5%), and six patients (9.3%) received supplementary medication. There were no difference in the median length of hospital stay (8 [6–13] days vs. 8 [6–12] days, p=0.786) and intensive care unit care (14 [10.1%] vs. 11 [16.7%], p=0.236) between the CT and non-CT groups, respectively. These findings remained consistent even after the propensity score matching. CONCLUSION: Utility of CT in patients with acute COPD exacerbation might not be helpful; therefore, we do not recommend chest CT scan as a routine initial diagnostic tool.

Hemophilia A in a Female Patient with Recurrent Vitreous Hemorrhage

PURPOSE@#To report a case of recurrent intraocular hemorrhage due to type A hemophilia in a female patient without any previous medical history.CASE SUMMARY: A 51-year-old female patient without any previous medical history was referred to our clinic due to blurred vision in her left eye. Slit lamp microscopy of the anterior segment was nonspecific. Fundus examination revealed vitreous hemorrhage with retinal tear in her left eye. Vitrectomy and cataract surgery were performed. One day after surgery, hyphema and vitreous hemorrhage recurred. A coagulation disorder was suspected and further serological evaluation was conducted. Coagulation factor analyses showed that the activity of coagulation factors 8 and 12 decreased to 25% and 47%, respectively. Genetic sequence analyses were conducted, and a missense mutation of C6724G> A] was found in exon 25, and type A hemophilia was confirmed.@*CONCLUSIONS@#In patients who tend to show persistent bleeding even after proper treatment, hematological evaluation including coagulation factor assays, and the possibility of rare diseases such as hemophilia should be considered.

Endophthalmitis after Cataract Surgery in Korea: A Nationwide Study Evaluating Incidence and Risk Factors in a Korean Population

PURPOSE: To assess the nationwide rate of acute postoperative endophthalmitis (APE) after cataract extraction in Korea and to evaluate potential risk factors thereof. MATERIALS AND METHODS: Nationwide insurance claims data from July 2014 to June 2017 were reviewed. All patients with phacoemulsification or extracapsular/intracapsular cataract extraction were included. Exclusion criteria were combined glaucoma surgery or total vitrectomy or when the patient had a history of intraocular foreign body. RESULTS: In total, 1505103 cases (982203 patients) were included. APE developed in 953 cases (938 patients) with an overall incidence of 0.063%. After adjusting for possible confounding factors, male sex [odds ratio (OR) 1.42; 95% confidence interval (CI) 1.25–1.61; p<0.001], primary clinical setting, operations performed in non-major cities, usage of sutures (OR 2.82; 95% CI 2.13–3.74; p<0.001), anterior vitrectomy (OR 8.71; 95% CI 6.71–11.32; p<0.001), aphakic cataract surgery (OR 1.52; 95% CI 1.03–2.22; p=0.033), hypertension (OR 1.40; 95% CI 1.18–1.66; p<0.001), diabetes (OR 1.59; 95% CI 1.31–1.93; p<0.001), and chronic renal failure (OR 1.28; 95% CI 1.01–1.62; p=0.039) were found to be related to APE development. CONCLUSION: The incidence of APE after cataract extraction was consistent with reports from other studies. Additional research is needed to determine the relationship of newly found risk factors, such as hypertension, primary clinical setting, chronic renal failure, and usage of suturing, with APE development.

Successful treatment of central retinal artery occlusion using hyperbaric oxygen therapy

Central retinal artery occlusion (CRAO) is considered an ophthalmologic emergency. The prognosis of this disease is very poor. Currently, there is no generally effective therapy available to treat CRAO. Hyperbaric oxygen therapy (HBOT) can increase the volume of oxygen delivered to the ischemic retinal tissue until spontaneous or assisted reperfusion occurs. We report the case of a patient who experienced sudden visual loss due to CRAO that was treated with HBOT. The patient was an 81-year-old woman who presented with CRAO in her right eye (OD). She exhibited “hand motion” visual acuity before treatment. She underwent three sessions of HBOT at a pressure of 2.8 atmospheres absolute, performed over 3 days. After 4 days in hospital, her visual acuity improved to 0.4 (OD) for far vision and 0.5 (OD) for near vision. Her vision was stable without the supply of oxygen; therefore, she was discharged.

Visual Recovery after Macular Hole Surgery and Related Prognostic Factors

PURPOSE: To describe the visual recovery and prognostic factors after macular hole surgery. METHODS: A retrospective chart review was conducted. Charts of patients with idiopathic macular holes who underwent surgery by a single surgeon at Severance Hospital between January 1, 2013 and July 31, 2015 were reviewed. The best-corrected visual acuity (BCVA) score was recorded preoperatively and at 1 day and 1, 3, 6, 9, and 12 months after surgery. The variables of age, sex, macular hole size, basal hole diameter, choroidal thickness, and axial length were also noted. RESULTS: Twenty-six eyes of 26 patients were evaluated. Twenty-five patients (96.2%) showed successful macular hole closure after the primary operation. The BCVA stabilized 6 months postoperatively. A large basal hole diameter (p = 0.006) and thin choroid (p = 0.005) were related to poor visual outcomes. Poor preoperative BCVA (p < 0.001) and a thick choroid (p = 0.020) were associated with greater improvement in BCVA after surgery. CONCLUSIONS: Visual acuity stabilized by 6 months after macular hole surgery. Choroidal thickness was a protective factor for final BCVA and visual improvement after the operation.

Incidence and Risk Factors of Cystoid Macular Edema after Vitrectomy with Silicone Oil Tamponade for Retinal Detachment

PURPOSE: To investigate the incidence and risk factors of cystoid macular edema (CME) after silicone oil (SO) injection for retinal detachment. METHODS: Fifty-eight patients with retinal detachment treated by vitrectomy with SO tamponade during 2011 to 2015 were retrospectively assigned to CME and non-CME groups. Patients underwent complete ophthalmological examination, including color fundus photography and preoperative and postoperative optical coherence tomography. Risk factors for CME during SO tamponade were determined by regression analyses. RESULTS: Of the 58 eyes, 21 (36.2%) exhibited CME. The presence of posterior staphyloma in the CME group was significantly more frequent than in the non-CME group (p = 0.026). There were no significant differences in other demographic or clinical characteristics between the CME and non-CME groups. Significant correlations were observed between CME after vitrectomy with SO tamponade and the presence of posterior staphyloma (odds ratio, 4.03; p = 0.031). Of the 21 eyes with CME, 13 underwent SO removal, among which 11 experienced resolution of CME with or without further intervention. CONCLUSIONS: The presence of posterior staphyloma is significantly associated with CME after vitrectomy with SO tamponade. Patients with retinal detachment exhibiting posterior staphyloma should be evaluated for potential CME during SO tamponade.

Polyetheretherketone Cage with Demineralized Bone Matrix Can Replace Iliac Crest Autografts for Anterior Cervical Discectomy and Fusion in Subaxial Cervical Spine Injuries

OBJECTIVE: This study aimed to compare the clinical and radiologic outcomes of patients with subaxial cervical injury who underwent anterior cervical discectomy and fusion (ACDF) with autologous iliac bone graft or polyetheretherketone (PEEK) cages using demineralized bone matrix (DBM). METHODS: From January 2005 to December 2010, 70 patients who underwent one-level ACDF with plate fixation for post-traumatic subaxial cervical spinal injury in a single institution were retrospectively investigated. Autologous iliac crest grafts were used in 33 patients (Group I), whereas 37 patients underwent ACDF using a PEEK cage filled with DBM (Group II). Plain radiographs were used to assess bone fusion, interbody height (IBH), segmental angle (SA), overall cervical sagittal alignment (CSA, C2–7 angle), and development of adjacent segmental degeneration (ASD). Clinical outcome was assessed using a visual analog scale (VAS) for pain and Frankel grade. RESULTS: The mean follow-up duration for patients in Group I and Group II was 28.9 and 25.4 months, respectively. All patients from both groups achieved solid fusion during the follow-up period. The IBH and SA of the fused segment and CSA in Group II were better maintained during the follow-up period. Nine patients in Group I and two patients in Group II developed radiologic ASD. There were no statistically significant differences in the VAS score and Frankel grade between the groups. CONCLUSION: This study showed that PEEK cage filled with DBM, and plate fixation is at least as safe and effective as ACDF using autograft, with good maintenance of cervical alignment. With advantages such as no donor site morbidity and no graft-related complications, PEEK cage filled with DBM, and plate fixation provide a promising surgical option for treating traumatic subaxial cervical spine injuries.

Long-term outcomes of surgery for chronic thromboembolic pulmonary hypertension compared with medical therapy at a single Korean center

BACKGROUND/AIMS: Pulmonary endarterectomy (PEA) is the gold standard for treating chronic thromboembolic pulmonary hypertension (CTEPH) in Western countries. The aim of this study was to investigate the long-term outcomes of performing PEA on CTEPH patients in comparison with medical therapy at a single Korean center. METHODS: This retrospective study included 88 CTEPH patients. These patients were classified into the PEA group (n = 37) or non-PEA group (i.e., medical therapy; n = 51). The clinical characteristics, hemodynamic data, and long-term survival rates were compared. Independent prognostic factors for CTEPH were also investigated. RESULTS: CTEPH was not associated with either gender, and the mean age at diagnosis was 53.3 ± 13.7 years. Echocardiography revealed that the mean peak velocity of the tricuspid regurgitation jet was 4.2 ± 0.7 m/sec and the mean pulmonary arterial pressure was 51.7 ± 15.1 mmHg. The PEA and non-PEA groups demonstrated no significant differences, except in terms of the right ventricular end-diastolic diameter. The survival rates of the PEA group were significantly higher than the non-PEA group at 1, 3, 5, and 10 years (p = 0.032). Multivariate analyses indicated that World Health Organization class IV and PEA were significant predictors of poorer and better outcomes, respectively. CONCLUSIONS: PEA demonstrates more favorable effects on long-term survival than medical therapy in Korean CTEPH patients who were considered operable.

Quality of Life and Visual Efficiency: fifth Korea National Health and Nutrition Examination Survey

PURPOSE: To analyze the association of visual efficiency and quality of life using data from the fifth Korea National Health and Nutrition Examination Survey (KNHANES V). METHODS: The present study included 5,244 glaucoma or glaucoma suspect subjects who completed a visual acuity test, visual field test and health-related questionnaire from the KNHANES V. Visual efficiency was calculated using best corrected visual acuity and visual field test. Quality of life was assessed with EuroQoL 5D (EQ-5D). Visual efficiency was compared with best corrected vision of the better eye to evaluate the relationship with quality of life. One-way analysis of variance (ANOVA) and partial correlations analysis were used to analyze the associations between factors. RESULTS: Both visual efficiency and best corrected visual acuity of the better eye were significantly different with all EQ-5D parameters (p < 0.005). After controlling for age, gender, income, education, spouse and house ownership, visual efficiency showed a positive correlation coefficient of +0.040 (p = 0.006) with the quality of life and the best corrected visual acuity of the better eye showed negative correlation coefficient of -0.044 (p = 0.002) with the quality of life. CONCLUSIONS: Visual efficiency was associated with the quality of life. Not only visual acuity but also visual efficiency would be a valuable parameter when considering the quality of life. Further studies are needed to evaluate non-glaucomatous populations.

Clinical and Angiographic Predictors of Microvascular Dysfunction in ST-Segment Elevation Myocardial Infarction

PURPOSE: We aimed to discover clinical and angiographic predictors of microvascular dysfunction using the index of microcirculatory resistance (IMR) in patients with ST-segment elevation myocardial infarction (STEMI). MATERIALS AND METHODS: We enrolled 113 patients with STEMI (age, 56+/-11 years; 95 men) who underwent primary percutaneous coronary intervention (PCI). The IMR was measured with a pressure sensor/thermistor-tipped guidewire after primary PCI. The patients were divided into three groups based on IMR values: Low IMR [31 U (48.1+/-17.1 U), n=37]. RESULTS: The age of the Low IMR group was significantly lower than that of the Mid and High IMR groups. The door-to-balloon time was <90 minutes in all patients, and it was not significantly different between groups. Meanwhile, the symptom-onset-to-balloon time was significantly longer in the High IMR group, compared to the Mid and Low IMR groups (p<0.001). In the high IMR group, the culprit lesion was found in a proximal location significantly more often than in a non-proximal location (p=0.008). In multivariate regression analysis, age and symptom-onset-to-balloon time were independent determinants of a high IMR (p=0.013 and p=0.003, respectively). CONCLUSION: Our data suggest that age and symptom-onset-to-balloon time might be the major predictors of microvascular dysfunction in STEMI patients with a door-to-balloon time of <90 minutes.

Delayed Pneumocephalus Following Fluoroscopy Guided Cervical Interlaminar Epidural Steroid Injection: A Rare Complication and Anatomical Considerations

Cervical epidural steroid injection is indicated for radicular symptoms with or without axial neck pain. Complications are rare but can be serious. Here, we report the case of a 54-year-old man with cervical radicular pain who was treated with cervical epidural steroid injection. Injection was administered twice under fluoroscopic guidance with the loss-of-resistance technique using air to confirm the epidural space. After the second procedure, the patient complained of severe persistent headache and was diagnosed with pneumocephalus on brain computed tomography. The patient returned home without any neurological complication, after a few days of conservative treatment. Though, a fluoroscopic guidance cervical epidural injection is also known to diminish the risk of complications. Physicians should always keep in mind that it does not guarantee safety, particularly in the cervical region, related to its anatomical considerations.
