Summary Background The effect of the addition of adjuvant chemotherapy to concurrent chemoradiotherapy in locoregionally advanced nasopharyngeal carcinoma is unclear. We aimed to assess the ...contribution of adjuvant chemotherapy to concurrent chemoradiotherapy versus concurrent chemoradiotherapy alone. Methods We did an open-label phase 3 multicentre randomised controlled trial at seven institutions in China. Randomisation was by a computer-generated random number code. Patients were stratified by treatment centre and randomly assigned in blocks of four. Treatment allocation was not masked. We randomly assigned patients with non-metastatic stage III or IV (except T3–4N0) nasopharyngeal carcinoma to receive concurrent chemoradiotherapy plus adjuvant chemotherapy or concurrent chemoradiotherapy alone. Patients in both groups received 40 mg/m2 cisplatin weekly up to 7 weeks, concurrently with radiotherapy. Radiotherapy was given as 2·0–2·27 Gy per fraction with five daily fractions per week for 6–7 weeks to a total dose of 66 Gy or greater to the primary tumour and 60–66 Gy to the involved neck area. The concurrent chemoradiotherapy plus adjuvant chemotherapy group subsequently received 80 mg/m2 adjuvant cisplatin and 800 mg/m2 per day fluorouracil for 120 h every 4 weeks for three cycles. Our primary endpoint was failure-free survival. We did efficacy analyses in our intention-to-treat population. Our trial is ongoing; in this report we present the 2 year survival results and acute toxic effects. This trial is registered with ClinicalTrials.gov , number NCT00677118. Findings 251 patients were assigned to the concurrent chemoradiotherapy plus adjuvant chemotherapy group and 257 to the concurrent chemoradiotherapy alone group. After a median follow-up of 37·8 months (range 1·3–61·0), the estimated 2 year failure-free survival rate was 86% (95% CI 81–90) in the concurrent chemoradiotherapy plus adjuvant chemotherapy group and 84% (78–88) in concurrent chemoradiotherapy only group (hazard ratio 0·74, 95% CI 0·49–1·10; p=0·13). Stomatitis was the most commonly reported grade 3 or 4 adverse event during both radiotherapy (76 of 249 patients in the concurrent chemoradiotherapy plus adjuvant chemotherapy group and 82 of 254 in the concurrent chemoradiotherapy alone group) and adjuvant chemotherapy (43 21% of 205 patients treated with adjuvant chemotherapy). Interpretation Adjuvant cisplatin and fluorouracil chemotherapy did not significantly improve failure-free survival after concurrent chemoradiotherapy in locoregionally advanced nasopharyngeal carcinoma. Longer follow-up is needed to fully assess survival and late toxic effects, but such regimens should not, at present, be used outside well-designed clinical trials.

Summary Background The value of adding cisplatin, fluorouracil, and docetaxel (TPF) induction chemotherapy to concurrent chemoradiotherapy in locoregionally advanced nasopharyngeal carcinoma is ...unclear. We aimed to compare TPF induction chemotherapy plus concurrent chemoradiotherapy with concurrent chemoradiotherapy alone in a suitably powered trial. Methods We did an open-label, phase 3, multicentre, randomised controlled trial at ten institutions in China. Patients with previously untreated, stage III–IVB (except T3-4N0) nasopharyngeal carcinoma, aged 18–59 years without severe comorbidities were enrolled. Eligible patients were randomly assigned (1:1) to receive induction chemotherapy plus concurrent chemoradiotherapy or concurrent chemoradiotherapy alone (three cycles of 100 mg/m2 cisplatin every 3 weeks, concurrently with intensity-modulated radiotherapy). Induction chemotherapy was three cycles of intravenous docetaxel (60 mg/m2 on day 1), intravenous cisplatin (60 mg/m2 on day 1), and continuous intravenous fluorouracil (600 mg/m2 per day from day 1 to day 5) every 3 weeks before concurrent chemoradiotherapy. Randomisation was by a computer-generated random number code with a block size of four, stratified by treatment centre and disease stage (III or IV). Treatment allocation was not masked. The primary endpoint was failure-free survival calculated from randomisation to locoregional failure, distant failure, or death from any cause; required sample size was 476 patients (238 per group). We did efficacy analyses in our intention-to-treat population. The follow-up is ongoing; in this report, we present the 3-year survival results and acute toxic effects. This trial is registered with ClinicalTrials.gov , number NCT01245959. Findings Between March 1, 2011, and Aug 22, 2013, 241 patients were assigned to induction chemotherapy plus concurrent chemoradiotherapy and 239 to concurrent chemoradiotherapy alone. After a median follow-up of 45 months (IQR 38–49), 3-year failure-free survival was 80% (95% CI 75–85) in the induction chemotherapy plus concurrent chemoradiotherapy group and 72% (66–78) in the concurrent chemoradiotherapy alone group (hazard ratio 0·68, 95% CI 0·48–0·97; p=0·034). The most common grade 3 or 4 adverse events during treatment in the 239 patients in the induction chemotherapy plus concurrent chemoradiotherapy group versus the 238 patients in concurrent chemoradiotherapy alone group were neutropenia (101 42% vs 17 7%), leucopenia (98 41% vs 41 17%), and stomatitis (98 41% vs 84 35%). Interpretation Addition of TPF induction chemotherapy to concurrent chemoradiotherapy significantly improved failure-free survival in locoregionally advanced nasopharyngeal carcinoma with acceptable toxicity. Long-term follow-up is required to determine long-term efficacy and toxicities.

Summary Background Icotinib, an oral EGFR tyrosine kinase inhibitor, had shown antitumour activity and favourable toxicity in early-phase clinical trials. We aimed to investigate whether icotinib is ...non-inferior to gefitinib in patients with non-small-cell lung cancer. Methods In this randomised, double-blind, phase 3 non-inferiority trial we enrolled patients with advanced non-small-cell lung cancer from 27 sites in China. Eligible patients were those aged 18–75 years who had not responded to one or more platinum-based chemotherapy regimen. Patients were randomly assigned (1:1), using minimisation methods, to receive icotinib (125 mg, three times per day) or gefitinib (250 mg, once per day) until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival, analysed in the full analysis set. We analysed EGFR status if tissue samples were available. All investigators, clinicians, and participants were masked to patient distribution. The non-inferiority margin was 1·14; non-inferiority would be established if the upper limit of the 95% CI for the hazard ratio (HR) of gefitinib versus icotinib was less than this margin. This study is registered with ClinicalTrials.gov , number NCT01040780 , and the Chinese Clinical Trial Registry, number ChiCTR-TRC-09000506. Findings 400 eligible patients were enrolled between Feb 26, 2009, and Nov 13, 2009; one patient was enrolled by mistake and removed from the study, 200 were assigned to icotinib and 199 to gefitinib. 395 patients were included in the full analysis set (icotinib, n=199; gefitinib, n=196). Icotinib was non-inferior to gefitinib in terms of progression-free survival (HR 0·84, 95% CI 0·67–1·05; median progression-free survival 4·6 months 95% CI 3·5–6·3 vs 3·4 months 2·3–3·8; p=0·13). The most common adverse events were rash (81 41% of 200 patients in the icotinib group vs 98 49% of 199 patients in the gefitinib group) and diarrhoea (43 22% vs 58 29%). Patients given icotinib had less drug-related adverse events than did those given gefitinib (121 61% vs 140 70%; p=0·046), especially drug-related diarrhoea (37 19% vs 55 28%; p=0·033). Interpretation Icotinib could be a new treatment option for pretreated patients with advanced non-small-cell lung cancer.

Summary Background Endoscopically assisted selective neck dissection (SND) has recently been applied in clinical N0 cases of oral squamous cell carcinoma (OSCC). However, nothing is known of the ...immune response after surgery. Methods A total of 60 patients with cT1-2N0 OSCC randomly underwent endoscopically assisted SND and open operations. The serum levels of IL-6, IL-8, IL-10, IL-1b, TNF-a, CRP, cortisol, ACTH, and growth hormone were analyzed before the start of the surgery(T0) and at 2(T1), 6(T2), 24(T3), and 72 hours (T4) after surgery. Results A total of 31 patients were randomized for endoscopic SND, whereas 29 underwent open procedures. The release of IL-6, IL-10 and CRP was significantly lower in the endoscopic group than in the open surgery group (p<0.05), and cortisol levels were also lower in the endoscopic group (p<0.05). Conclusions Endoscopic SND could effectively provide lower inflammatory responses and surgical stress, reducing peri-operative trauma and accelerating recovery.
Abstract Background Acute-on-chronic liver failure (ACLF) is a severe clinical condition for which liver transplantation (LT) is the only curative option. However, there are little published data on ...risk factors and outcomes of LT for ACLF. Methods The objective of this study was to analyze preoperative, intraoperative, postoperative, and overall survival data on 100 consecutive cases with ACLF in order to try to determine for which patients LT are futile. Results One hundred consecutive patients with pathology-confirmed ACLF who underwent LT from June 2004 to September 2012 were enrolled. The preoperative data showed that all patients were in a serious condition with a median high model for end-stage liver disease (MELD) score of 32, total bilirubin of 440.20 umol/L, international normalized ratio (INR) of 3.012, and at least one organ dysfunction as assessed by a Sequential Organ Failure Assessment (SOFA) score of ≥9. The patients had either deceased or a living donor LT with an overall mortality of 20%. The 1-, 3-, and 5-year cumulative survival rates were 76.8%, 75.6%, and 74.1%, respectively, and graft 1-, 3-, and 5-y accumulative survival rates were 73.3%, 72.1%, and 70.6%, respectively. However, the area under receiver operating characteristic of SOFA score, MELD score, as well as Child-Pugh score were 0.552, 0.547, and 0.547, respectively. Conclusions Both deceased and living donor LT are effective therapeutic options for patients with ACLF and the short- and long-term survival rates are encouraging. It is important to conduct more prospective and multi-center studies to define preoperatively which patients would benefit from LT.
Abstract Objective The advantages and limitations of the endoscopy-assisted transoral approach(EATA) and external approaches(EAs) in resection of parapharyngeal space tumors(PSTs) remain unclear. ...Here, we compared the use of the EATA and EAs for the resection of large benign PSTs. Study design Forty-four patients with parapharyngeal space tumors were divided into the EATA and EA groups. The perioperative and postoperative outcomes of the patients were evaluated. Results All of the tumors were completely removed. However, the procedure was converted to an open procedurefor four patients in the EATA group, and six patients in the EA group required endoscopic assistance. The intraoperative blood loss, amount and duration of drainage, postoperative pain, total hospital stay and cosmetic outcomes were superior in the EATA group(P<0.05). Conclusion Use of the EATA for resection of large benign PSTs advantageously decreased the surgical invasiveness of the procedure and resulted in better aesthetic results. However, use of the combined surgical approach allowed for improved access for the resection of PSTs.
Percutaneous device occlusion and minimally invasive surgical repair for perimembranous ventricular septal defect (pmVSD) are two typical methods to reduce the invasiveness of the conventional ...operation through a median sternotomy. However, few studies have compared them in terms of effectiveness and cost.
Inpatients with isolated pmVSD who had undergone percutaneous device occlusion or minimally invasive surgical repair from June 2009 to June 2012 were reviewed for a comparative investigation between the two procedures.
Procedure success was achieved in 80 percutaneous (93.0%) and in 113 surgical (98.3%) procedures (p=0.076). Percutaneous patients were older, with a smaller VSD size than surgical patients (16±11.7 vs 3.8±2.4 mm, p<0.001; 4.0±1.2 vs 4.3±1.3 mm, p=0.034, respectively). Major complications occurred in 1 percutaneous (1.2%) and in 4 surgical (3.5%) procedures (p=0.602), and minor complications occurred in 27 percutaneous (33.3%) and in 37 surgical (32.2%) procedures (p=0.991). The surgical repair cost 31% less than the device occlusion (¥20,565±¥3,497 vs ¥29,795±¥2,643, p<0.001), where most of the cost was attributed to the occluder in the amount of ¥19,500.
Compared with device occlusion, minimally invasive surgical repair can provide comparable efficacy and complication rates. In addition, it is 31% cheaper than device occlusion. In low-income countries where health care resources are limited, medical resources must be judiciously allocated to the treatment that allows for effective treatment of the largest number of patients.
Chronic urticaria (CU) is a debilitating skin disease that lasts for more than 6 weeks with wheals and/or angioedema, including chronic spontaneous urticaria (CSU) and chronic inducible urticaria ...(CIndU). In China, the prevalence of this disease is high, more than 1%, and on the rise. CU has a major impact on the quality of life (QoL) of patients who frequently experience sleep disturbance, depression, and anxiety. Nearly one-third of patients with CSU, in China, are resistant to second-generation H1-antihistamines (sgAHs), even at a fourfold dose (second line; off-label). Omalizumab is approved for the treatment of CSU treatment in Europe and shows remarkable efficacy and safety. In China, regulatory approval for the use of omalizumab is pending, and its use in clinical practice varies widely. Consensus on omalizumab CU treatment in China is urgently needed. The aim of this article is to propose a practical omalizumab treatment algorithm for the management of antihistamine-resistant CSU and CIndU in adults and special population including children and adolescents, and pregnant or breast feeding women, to guide daily clinical practice in China. In the development of this consensus, an expert group including mainly dermatologists, allergists, but also pulmonologists, ENTs, immunologists, and pediatricians in Allergic Disease Prevention and Control Committee, Chinese Preventive Medicine Association, reviewed the existing evidence and developed consensus on the use of omalizumab in CU patients from China. The goal of this consensus is to assist clinicians in making rational decisions in the management of refractory CU with omalizumab. The key clinical questions covered by the treatment algorithm are: 1) Omalizumab treatment routine strategy in both CSU and CIndU patients; 2) Recommended dose and treatment duration for different age stratification; 3) Treatment duration for CU patients with other allergic comorbidities; 4) Recommendation on omalizumab stopping strategy.
To analyze patterns of local-regional failure (LRF) for completely resected stage IIIA(N2) non-small cell lung cancer (NSCLC) patients treated in our hospital and to propose a clinical target volume ...(CTV) for postoperative radiation therapy (PORT) in these patients.
From 2005 to 2011, consecutive patients with pT1-3N2 NSCLC who underwent complete resection in our hospital but who did not receive PORT were identified. The patterns of first LRF were assessed and evaluated as to whether these areas would be encompassed by our proposed PORT CTV.
With a median follow-up of 24 months, 173 of 250 patients (69.2%) experienced disease recurrence. Of the 54 patients with LRF as the first event, 48 (89%) had recurrence within the proposed PORT CTV, and 6 (11%) had failures occurring both within and outside the proposed CTV (all of which occurred in patients with right-lung cancer). Ninety-three percent of failure sites (104 of 112) would have been contained within the proposed PORT CTV. For left-sided lung cancer, the most common lymph node station failure site was 4R, followed by 7, 4L, 6, 10L, and 5. For right-sided lung cancer, the most common site was station 2R, followed by 10R, 4R, and 7.
LRF following complete surgery was an important and potentially preventable pattern of failure in stage IIIA(N2) patients. Ipsilateral superior mediastinal recurrences dominated for right-sided tumors, whereas left-sided tumors frequently involved the bilateral superior mediastinum. Most of the LRF sites would have been covered by the proposed PORT CTV. A prospective investigation of patterns of failure after PORT (following our proposed CTV delineation guideline) is presently underway and will be reported in a separate analysis.
Background The parathyroidectomy assessment of symptoms (PAS) score was designed initially for primary hyperparathyroidism to provide a specific symptom assessment and was validated later in ...secondary and tertiary hyperparathyroidism. The aim of our study was to evaluate changes in the PAS scores and quality of life before and after parathyroidectomy for secondary hyperparathyroidism. Methods This prospective study included 49 consecutive patients who underwent parathyroidectomy for secondary hyperparathyroidism. The PAS and Short Form (SF)-36 questionnaires were completed before parathyroidectomy and at 12 months postoperatively. Results All 13 symptoms included in the PAS score improved significantly. The mean ± standard deviation PAS score decreased from 545 ± 263 to 284 ± 201 ( P < .0001) after parathyroidectomy. Quality of life was enhanced in both physical (40.3 ± 17.1 to 59.0 ± 14.9; P < .0001) and mental (47.6 ± 17.1 to 63.7 ± 13.0; P < .0001) components. The PAS score was inversely correlated with the SF-36 global score preoperatively and postoperatively ( r2 = 0.48 and 0.25; P < .001). The change in PAS score also correlated with the change in SF-36 global score ( r2 = 0.29; P < .001). Multiple linear regression analysis showed that preoperative PAS score and bone mineral density T-score were predictors of the decrease in PAS score. Preoperative SF-36 global score and intact parathyroid hormone levels were predictors of the increment in SF-36 score. Conclusion The symptom burden of secondary hyperparathyroidism has a negative impact on a patient's quality of life. Parathyroidectomy is associated with a marked improvement in symptoms and quality of life.
