Geriatric Nutritional Risk Index as a prognostic marker in patients with extensive-stage disease small cell lung cancer: Results from a randomized controlled trial.

BACKGROUND: Clinical impact of the Geriatric Nutritional Risk Index (GNRI) in patients with extensive-stage disease small cell lung cancer (ED-SCLC) have not previously been reported. METHODS: This study analyzed 352 patients enrolled in a previous randomized phase III trial comparing the efficacy of irinotecan plus cisplatin with that of etoposide plus cisplatin as the first-line therapy for ED-SCLC. GNRI values were calculated using serum albumin levels and actual and ideal bodyweights. Patients with a GNRI > 98, 92-98, and <92 were grouped into no, low, and moderate/major risk groups, respectively. RESULTS: The objective response rates were 63.2%, 52.6%, and 49.2% in the no, low, and moderate/major risk groups, respectively (P = 0.024). The median progression-free survival (PFS) was shorter in patients with a lower GNRI than in those with a higher GNRI (no vs. low vs. moderate/major risk group; 6.5 vs. 5.8 vs. 5.9 months, respectively; P = 0.028). There were significant differences in median overall survival (OS) according to GNRI (no vs. low vs. moderate/major risk group; 13.2 vs. 10.3 vs. 8.4 months, respectively; P < 0.001). Multivariate analysis revealed that being in the moderate/major risk group was an independent poor prognostic factor for PFS (hazard ratio [HR]: 1.300, 95% confidence interval [CI]: 1.012-1.670; P = 0.040) and OS (HR: 1.539; 95% CI: 1.069-2.216; P = 0.020). CONCLUSIONS: This prospective study shows that a low GNRI value was associated with a poor prognosis, and it supports the relationship between systemic inflammation, nutritional status, and clinical outcomes in patients with ED-SCLC.Key points SIGNIFICANT FINDINGS OF THE STUDY: The lower GNRI group had a low response rate to chemotherapy for ED-SCLC. The HRs for PFS and OS were 1.300 and 1.539 in the patients with GNRI < 92. WHAT THIS STUDY ADDS: Low GNRI is associated with poor prognosis in ED-SCLC.

Prescription Trends of Psychotropics in Children and Adolescents with Autism Based on Nationwide Health Insurance Data.

Children with autism are often medicated to manage emotional and behavioral symptoms; yet, data on such pharmacotherapy is insufficient. In this study, we investigated the Korean National Health Insurance Claims Database (NHICD) information related to autism incidence and psychotropic medication use. From the 2010-2012 NHICD, we selected a total of 31,919,732 subjects under 19 years old. To examine the diagnostic incidence, we selected patients who had at least one medical claim containing an 10th revision of International Statistical Classification of Diseases and Related Health Problems (ICD-10) code for pervasive developmental disorder, F84, not diagnosed in the previous 360 days. Psychotropics were categorized into seven classes. Then, we analyzed the data to determine the mean annual diagnostic incidence and psychotropic prescription trends. Diagnostic incidence was 17,606 for the 3 years, with a mean annual incidence per 10,000 population of 5.52. Among them, 5,348 patients were prescribed psychotropics. Atypical antipsychotics were the most commonly used, followed by antidepressants. An older age, male sex, and the availability of medical aid were associated with a higher rate of prescription than observed for a younger age, female sex, and the availability of health insurance. Psychotropic drugs were used for less than one-third of patients newly diagnosed with autism, and prescription differed by sex and age. Increased diagnostic incidence is associated with an increased prescription of psychotropic drugs. Therefore, medication-related safety data and policies for psychotropic drugs in autism should be prepared.

Utilization of Western and Traditional Korean Medicine for Children and Adolescents with Mental Disorders: a Nationwide Population-based Study from 2010 to 2012.

When in need of medical treatment, Korean citizens have a choice of practitioners of western medicine (WM) or Traditional Korean Medicine (TKM). However, the two branches frequently conflict with one another, particularly with regard to mental disorders. This study was designed to compare the utilization of WM and TKM, focusing on child/adolescent patients with mental disorders. We analyzed F-code (Mental and behavioral disorders) claims from the Korean Health Insurance Review and Assessment Service, including data from 0-18-year-old patients from 2010 to 2012. Slightly more men than women utilized WM, while TKM use was almost evenly balanced. WM claims increased with advancing age, whereas utilization of TKM was common for the 0-6 age group. In WM and TKM, the total number of claims relying on the National Health Insurance Service (NHIS) was 331,154 (92.78%) and 73,282 (97.85%), respectively, and the number of claims relying on medical aid was 25,753 (7.22%) and 1,610 (2.15%), respectively. The most frequent F-coded claim in WM was F90 (Hyperkinetic disorders), with 64,088 claims (17.96%), and that in TKM was F45 (Somatoform disorders), with 28,852 claims (38.52%). The prevalence of a single disorder without comorbidities was 168,764 (47.29%) in WM and 52,615 (70.25%) in TKM. From these data, we conclude that WM takes prevalence over TKM in cases of attention deficit/hyperactivity disorder (ADHD), as well as in psychological problems such as depression and anxiety. On the other hand, patients utilizing TKM more commonly present with physical health problems including somatoform problems, sleep, and eating disorders.

A phase II study of docetaxel and oxaliplatin combination in recurrent gastric cancer patients after fluoropyrimidine and/or cisplatin adjuvant treatment: a Korean Cancer Study Group Protocol ST06-02.

BACKGROUND: Surgery alone is no longer an adequate standard of care for patients with resectable gastric cancer. Thus, research efforts should focus on which regimens are the most effective for patients with recurrent gastric cancer after combined treatment with surgery and perioperative or adjuvant chemotherapy. METHODS: Patients with histologically confirmed and measurable advanced gastric cancer who showed a relapse even after fluoropyrimidine and/or cisplatin-based adjuvant chemotherapy received docetaxel (35 mg/m(2)) intravenously on day 1 and 8 plus oxaliplatin (100 mg/m(2)) intravenously on day 1 every 3 weeks until disease progression or unacceptable toxicity. RESULTS: A total of 34 patients with relapsed advanced gastric cancer who had received adjuvant chemotherapy with fluoropyrimidine and/or cisplatin for a median of 6 months (range, 1-48 months) were enrolled in this trial; 22 (64.7 %) patients had been exposed to both agents. Their median age was 58 years (range, 50-68 years). The overall response rate was 55.9 % (95 % confidence interval (CI), 38.3-73.5 %), including 1 complete response and 18 partial responses. At a median follow-up duration of 28.5 months (range, 9.2-50.7 months), the median progression-free survival for all patients was 5.3 months (95 % CI, 4.4-6.1 months) and the median overall survival was 13.8 months (95 % CI, 11.1-16.4 months). The most common grade 3 or 4 hematologic and nonhematologic toxicities were neutropenia (47.1 %) and diarrhea (17.6 %), respectively. Five patients (14.7 %) experienced febrile neutropenia. CONCLUSIONS: Docetaxel and oxaliplatin combination chemotherapy was active and tolerable in patients with recurrent gastric cancer after fluoropyrimidine and/or cisplatin-based adjuvant chemotherapy.

Adenocarcinoma has an excellent outcome with pemetrexed treatment in Korean patients: a prospective, multicenter trial.

OBJECTIVE: This prospective multicenter study conducted by the Korean Cancer Study Group evaluated the efficacy and safety of pemetrexed in Korean patients with advanced non-small cell lung cancer (NSCLC) who had prior chemotherapy. PATIENTS AND METHODS: Patients with stage IIIB or IV NSCLC in whom prior chemotherapy failed received pemetrexed 500 mg/m(2) every 3 weeks with folic acid and vitamin B12 supplementation until disease progression or the development of intolerable toxicity. Eighty-one patients were enrolled. RESULTS: The overall response rate for 78 evaluable patients was 5.1% [95% confidence interval (CI) 1.4-12.6; partial response 4/78, no complete response]. The disease control rate including complete, partial response and stable disease was 46.2% (36/78, 95% CI 34.8-57.8). With a median 8.7 months follow-up, the median time to progression was 3.1 months (95% CI 1.17-5.03) and the median overall survival (OS) was 7.8 months (95% CI 5.19-10.35). The median OS for patients with adenocarcinoma histology was 18.7 months compared to 6.1 months for non-adenocarcinoma. In a multivariate analysis, Eastern Cooperative Oncology Group performance status 0-1 [hazards ratio (HR)=0.331, 95% CI 0.135-0.814] and adenocarcinoma (HR=0.504, 95% CI 0.283-0.899) were independent factors for prolongation of overall survival. CONCLUSIONS: Pemetrexed monotherapy has promising efficacy in patients with advanced NSCLC as a second-line therapy with less hematologic and non-hematologic toxicity, especially in those with adenocarcinoma histology.

Discrepant views of Korean medical oncologists and cancer patients on complementary and alternative medicine.

PURPOSE: This study was designed to evaluate the communication gap between Korean medical oncologists and cancer patients on complementary and alternative medicine (CAM). MATERIALS AND METHODS: Cross sectional studies utilized the responses of 59 medical oncologists and 211 patients. To understand the communication gap, perceived reasons and nondisclosure of CAM use, reactions of physicians to disclosure, and expectations for CAM were analyzed. Data were compared with use of the chi-squared test. RESULTS: Both medical oncologists and patients were in accord that CAM use would provide the patients with a feeling of hope. The medical oncologists believed more often than patients to attribute CAM use for control over medical care decisions, for the treatment of an incurable disease or as a nontoxic approach (p<0.05). Regarding reasons for nondisclosure, medical oncologists were more likely to think that physicians would not understand the use of CAM, discontinue treatment or disapprove of the use of CAM (p<0.0001). Patients attributed nondisclosure mainly to the lack of questioning about CAM. Medical oncologists were more likely to warn of the risks with CAM use and less likely to encourage the use of CAM than perceived by patients (p=0.01). Patients expected that CAM could cure disease, extend survival, relieve symptoms and improve the immune system or quality of life more often than medical oncologists (p<0.05). CONCLUSION: Given the discrepant views of medical oncologists and patients on the use of CAM, medical oncologists should be aware of the discrepancies and attempt to resolve any differences.
