BackgroundAccording to the noninferiority result of chemoradiation with carboplatin in our previous nasopharyngeal carcinoma (NPC) study along with the inconclusive data on the efficacy of adjuvant chemotherapy (AC) following concurrent chemoradiotherapy (CCRT), we designed to assess the role of adjuvant carboplatin/fluorouracil following CCRT with carboplatin in locoregionally advanced NPC.Materials and MethodsA multicenter randomized trial was conducted at 5 cancer centers in Thailand. We enrolled in stage T2N0M0-T4N2M0 (American Joint Cancer Committee 7th edition) WHO Type 2 NPC patients. N3 or metastatic disease patients were excluded. Participants were randomized into 2 groups: CCRT plus AC group vs the CCRT alone group. Patients in both groups received weekly carboplatin 100 mg/m2 for 6 cycles concurrently with radiotherapy 69.96-70 Gy. Patients in the AC group subsequently received 3 cycles of carboplatin area under curve-5 plus 1000 mg/m2/day of fluorouracil infusion within 96 hours every 3 weeks. We report the 2-year overall survival (OS), disease-free survival (DFS), loco-regional recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS). Treatment-related toxicities and compliance were also explored.ResultsOf 175 patients, 82 (46.9%) were assigned to the AC group, and 93 (53.1%) to the CCRT group. The compliance rate during CCRT was 90% and 86% in the AC and CCRT group, whereas 81.7% during adjuvant treatment in the AC group. With a median follow-up time of 24.4 months (interquartile range 17.9-24.4), the 2-year OS rate was 89.6% in the AC group and 81.8% in the CCRT group (P= 0.167). The 2-year DFS rate was 86.8% in the AC group and 74.6% in the CCRT group (P = 0.042). The 2-year LRFS rate was 91.5% in the AC group and 88.2% in the CCRT group (P = 0.443). The 2-year DMFS rate was 85.4% in the AC group and 79.6% in the CCRT group (P = 0.294). The most frequent serious (grade 3/4) nonhematologic toxicity was acute mucositis, which occurred 5% in the AC group vs 4% in the CCRT group (P = 0.498). For hematologic toxicity, grade 3-4 leukopenia were found 10% and 5% in the adjuvant and CCRT groups, respectively (P = 0.003). Multivariate analyses determined stage N2 disease was an adverse prognostic factor associated with shorter OS, DFS, and DMFS. And the adjuvant treatment was a significant protective factor for only DFS.ConclusionsThe addition of adjuvant carboplatin/fluorouracil following CCRT with carboplatin significantly improved 2-year DFS in stage T2N0M0-T4N2M0 NPC albeit there was a nonsignificant trend in favor of a higher 2-year OS, LRFS, and DMFS. Long-term efficacy and late toxicities of AC still require exploration. 相似文献

A 34-year-old woman who presented with only severe headache for 12 days was reported. She was initially diagnosed with cerebral infarction of the right temporal lobe and treated with aspirin, without improvement. On admission, she had bilateral papilledema. Other findings were unremarkable. CT scan and MRI of the brain revealed an area of cerebritis at the right temporal lobe. Lumbar puncture showed high opening pressure with normal CSF profiles. The patient was treated with intravenous acyclovir which gave a favorable outcome. 相似文献

Pneumonia was the most common cause of death during the 2009 pandemic H1N1 influenza virus infection. Clinical risk factors for pneumonia caused by this virus are limited. We enrolled consecutive patients treated at the H1N1 Clinic in Thungsong Hospital in Nakhon Si Thammarat, Thailand, during June–December 2009 who had positive polymerase chain reaction results for H1N1 virus. Clinical features for patients given a diagnosis with and without pneumonia were studied. There were 441 patients with positive polymerase chain reaction results for H1N1 virus. Of these patients, 51 (11.56%) had pneumonia. Three independent clinical factors for H1N1 pneumonia were myalgia, dyspnea, and an absolute neutrophil count > 7,700 cells/μL. Adjusted odds ratios (95% confidence intervals) for these three variables were 0.413 (0.173–0.988), 2.625 (1.230–5.604), and 4.475 (1.882–10.644), respectively. Clinical features may be a useful tool for predicting risk for pneumonia caused by H1N1 virus. 相似文献

From the leaves of Goniothalamus tenuifolius, a new natural product namely 3'-hydroxy-3,5,7,4'-tetramethoxyflavone (1) was isolated, along with seven other known compounds (2-8). Each of these isolates was evaluated for free radical scavenging activity on the DPPH decoloration test. The data obtained in this study suggested that the ortho 3',4'-diphenolic structure was essential for the activity of these flavonol derivatives. 相似文献

Burkholderia pseudomallei, the causative agent of melioidosis, is endemic in northeastern Thailand. Population-based disease burden estimates are lacking and limited data on melioidosis exist from other regions of the country. Using active, population-based surveillance, we measured the incidence of bacteremic melioidosis in the provinces of Sa Kaeo (eastern Thailand) and Nakhon Phanom (northeastern Thailand) during 2006-2008. The average annual incidence in Sa Kaeo and Nakhon Phanom per 100,000 persons was 4.9 (95% confidence interval [CI] = 3.9-6.1) and 14.9 (95% CI = 13.3-16.6). The respective population mortality rates were 1.9 (95% CI = 1.3-2.8) and 4.4 (95% CI = 3.6-5.3) per 100,000. The case-fatality proportion was 36% among those with known outcome. Our findings document a high incidence and case fatality proportion of bacteremic melioidosis in Thailand, including a region not traditionally considered highly endemic, and have potential implications for clinical management and health policy. 相似文献

Retinol-binding protein 4 (RBP4) has been suggested as new adipokine, possibly linking obesity to type 2 diabetes mellitus (T2DM). Since the kidneys are the main site of RBP4 degradation and since renal failure is a frequent co-morbid condition with diabetes mellitus, we evaluated the association among RBP4, renal function and T2DM in an Asian population. RBP4 serum levels were analyzed in 110 subjects (50 with T2DM) using an enzyme-linked immunosorbent assay (ELISA). Based on a cut-off estimated glomerular filtration rate (eGFR) of 60 ml/min per 1.73 m2 (calculated according the abbreviated MDRD formula which uses serum creatinine level, age and gender) and on the T2DM status, subjects were assigned to four subgroups: Group A- controls with an eGFR > 60 ml/min per 1.73 m2, Group B - controls with an eGFR < 60 ml/min per 1.73 m2, Group C- T2DM subjects with an eGFR > 60 ml/min per 1.73 m2, and Group D - T2DM subjects with an eGFR < 60 ml/ min per 1.73 m2. In both the T2DM and control groups, RBP4 levels were higher in subjects with an eGFR < 60 ml/min per 1.73 m2 than in subjects with an eGFR > 60 ml/min per 1.73 m2. However, the difference was only significant between the control groups (p < 0.05). After adjusting for age, gender, BMI, eGFR and the presence of T2DM, eGFR, not T2DM, was associated with plasma RBP4 levels (p < 0.05). These results suggest among Asians the eGFR, but not the presence of T2DM, is a major determinant of RBP4 serum levels. The eGFR should be taken into account when evaluating the role of RBP4 in the pathogenesis of insulin resistance and T2DM. 相似文献

Sweet's syndrome (SS) is associated with various diseases including non‐tuberculous mycobacterial infection (NTM). Recent reports have shown that SS associated with NTM is increasing. Clinical features of SS associated with NTM may be different from SS associated with other associated diseases. The aim of the present study was to compare clinical parameters and treatment outcomes of SS associated with NTM and other associated diseases. Patients from January 2004 to April 2014 diagnosed with SS were retrospectively enrolled. Clinical variables were compared between SS patients with and without NTM infection. There were 51 SS patients during the study period; 36 patients (70.59%) had NTM. Clinical variables between the NTM and other associated diseases were comparable: age, sex, and pattern and locations of skin lesions. Five laboratory factors were significantly different between the groups including white blood cell counts (NTM 25 800 vs 12 850 cells/mm3), lymphocyte percentages (13.0% vs 18.7%), monocytes (3.0% vs 7.2%), blood urea nitrogen (BUN) (11.7 vs 8.1 mg/dL) and serum creatinine (Cr) (1.0 vs 0.7 mg/dL). The presence of markedly high white blood cell counts, a low percentage of mononuclear cells and high BUN/Cr levels in SS may be a clinical clue to recognize the association with NTM infections; particularly in dissemination. 相似文献
