Tamoxifen and radiotherapy are used in breast cancer treatment worldwide. Radiation recall dermatitis (RRD), induced by tamoxifen, has been rarely reported. Herein, we report a RRD case induced by tamoxifen. A 47-year-old woman had a right quadrantectomy and an axillary lymph node dissection due to breast cancer. The tumor was staged pT2N0; it was hormone receptor positive, and human epidermal growth factor receptor 2 negative. The patient received adjuvant chemotherapy followed by tamoxifen and radiotherapy. After 22 months of tamoxifen, the patient developed a localized heating sensation, tenderness, edema, and redness at the irradiated area of the right breast. The symptoms improved within 1 week without treatment. Three weeks later, however, the patient developed similar symptoms in the same area of the breast. She continued tamoxifen before and during dermatitis, and symptoms resolved within 1 week.

BACKGROUND: We evaluated the timing and route of arrival of patients with cancer referred to a hospital near their residence for end-of-life care.METHODS: The medical records of patients with cancer receiving palliative systemic treatment at other hospitals who were transferred to our hospital for terminal care were reviewed retrospectively.RESULTS: Records of 60 patients (mean age, 57.4 years) were reviewed. The median survival after transfer was 40 days; 56.3% and 43.3% of the patients were referred to the outpatient and emergency departments of our hospital, respectively. Only 45% of the patients were enrolled in the hospice palliative care system. The most common reason for not enrolling was rejection of the patients or their families for hospice palliative care.CONCLUSION: For end-of-life care, the time from the referral to death was short, and many patients were transferred to the emergency department of our hospital.

Pazopanib is a potent multitargeted tyrosine kinase inhibitor that has been shown to have good efficacy in patients with renal cell carcinoma. A previous phase II trial demonstrated that short-term pazopanib administration was generally well tolerated and showed antitumor activity in patients with early-stage non-small cell lung cancer. Herein, we report on the case of a 66-year-old man with simultaneous metastatic squamous cell carcinoma of the lung and renal cell carcinoma who was treated with pazopanib. The patient showed an unexpected partial response and experienced a 10-month progression-free survival without significant toxicity. To the best of the authors' knowledge, this is the first report of pazopanib treatment in a non-small cell lung cancer patient in Korea. The results in this patient suggest that pazopanib may be a valid treatment option for advanced non-small cell lung cancer.

PURPOSE: While tumor markers (carbohydrate antigen 19-9 [CA 19-9] and carcinoembryonic antigen [CEA]) can aid in the diagnosis of biliary tract cancer, their prognostic role has not been clearly elucidated. Therefore, this study was conducted to evaluate the prognostic role of tumor markers and tumor marker change in patients with advanced biliary tract cancer. MATERIALS AND METHODS: Patients with pathologically proven metastatic or relapsed biliary tract cancer who were treated in a phase II trial of first-line S-1 and cisplatin chemotherapy were enrolled. Serum tumor markers were measured at baseline and after the first cycle of chemotherapy. RESULTS: Among a total of 104 patients, 80 (77%) had elevated baseline tumor markers (69 with CA 19-9 elevation and 40 with CEA). A decline ≥ 30% of the elevated tumor marker level after the first cycle of chemotherapy conferred an improved time to progression (TTP), overall survival (OS), and better chemotherapy response. Multivariate analysis revealed tumor marker decline as an independent positive prognostic factor of TTP (adjusted hazard ratio [HR], 0.44; p=0.003) and OS (adjusted HR, 0.37; p < 0.001). Subgroup analysis revealed similar results in each group of patients with CA 19-9 elevation and CEA elevation. In addition, elevated baseline CEA was associated with poor survival in both univariate and multivariate analysis. CONCLUSION: Tumor marker decline was associated with improved survival in biliary tract cancer. Measuring tumor marker after the first cycle of chemotherapy can be used as an early assessment of treatment outcome.

BACKGROUND: Although the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation has been recommended for accurate estimates of glomerular filtration rate (eGFR), there is little information regarding differences in GFR estimates obtained using the Cockcroft-Gault (CG) or Modification of Diet in Renal Disease (MDRD) equations in East Asian cancer patients. We investigated discrepancies in GFR and toxicities in patients treated with cisplatin-based chemotherapy using three equations equations. METHODS: A total of 229 patients were retrospectively recruited. We calculated eGFR using the three equations and separated patients into three categories based on GFR < 10 (group A), 10–50 (group B), and > 50 (group C) mL/min/1.73m2. We analyzed chemotherapy toxicities. RESULTS: The mean eGFR calculated using the CG was the lowest of the values derived using the three equations. Estimates using the MDRD and CKD-EPI equations resulted in reclassifying 32 (71.1%) and 33 (73.3%) of 45 patients, originally placed in group B using the CG into group C. However, only 1 (7.7%) of 13 patients placed in group B using the MDRD were reclassified into group C using the CKD-EPI. Twenty-eight of 45 patients classified into group B using the CG equation were treated with reduced doses of cisplatin. However, these patients did not show significant differences in toxicities compared with other patients taking full doses of cisplatin. CONCLUSION: The CG equations underestimated GFR compared to the MDRD and CKD-EPI equations. Therefore, when GFR is estimated using CG equations, East Asian cancer patients may receive insufficient doses of chemotherapeutic agents, including cisplatin.

BACKGROUND AND OBJECTIVES: To improve hearing screening, we developed a more effective hearing screening questionnaire for infants and children to be utilized during medical check-ups. SUBJECTS AND METHOD: Through literature review and discussions with an advisory council, we selected 10 questions to ask parents at each of the seven screening periods for their infants and children. In total, 223 parents of infants and children with and without hearing impairment (119 normal hearing, 104 hearing impaired) answered questionnaires at seven university hospitals in Korea. The advisory council modified questions with regard to sensitivity, specificity, positive, and negative prediction rate, preventing duplication among screening periods, and to address other questions related to development. RESULTS: For hearing screens, we asked five questions per screening period. Collectively, these questions had 40-100% sensitivity and 45-90% specificity at each of the seven screening periods. CONCLUSION: Although we do not advise that hearing questionnaires replace hearing tests, we developed in this study a more effective questionnaire that we suggest could be utilized during medical check-ups to enhance the hearing screening process.

Background/Aims: Helicobacter pylori (H. pylori) infection highly correlates with erythematous/exudative gastritis, which is one of the endoscopic findings of the Sydney classification system. The present study aimed to evaluate the association between endoscopic severity of erythematous/exudative gastritis and H. pylori infection. Methods: We prospectively enrolled asymptomatic adults who were diagnosed with erythematous/exudative gastritis during screening esophagogastroduodenoscopy. A rapid urease test was performed in all participants to diagnose H. pylori infection. The severity of erythematous/exudative gastritis was determined based on the Sydney classification system. Two investigators independently evaluated the endoscopic findings. The primary endpoint was H. pylori infection rate according to the severity of erythematous/exudative gastritis (mild vs. moderate-to-severe). Results: A total of 177 patients with erythematous/exudative gastritis were included. The rate of H. pyloriinfection was 86.4% in all patients. Of 177 included patients, 78 were at mild degree, 48 were at moderate degree, and 51 were at severe degree. The inter-observer variation was 4.6% and kappa value was 0.593. H. pylori infection rate was similar between patients with mild erythematous/exudative gastritis and those with moderate-to-severe erythematous/exudative gastritis (91.0% vs. 82.8%, p=0.115). Even after adjusting potential confounding variables, the severity of erythematous/exudative gastritis was not associated with H. pylori infection rate. Conclusions H. pylori infection is commonly observed in patients with erythematous/exudative gastritis. However, the severity of erythematous/exudative gastritis is not associated with H. pylori infection rate.
