Objective To investigate the accuracy of CTVision image-guided stereotactic body radiation therapy (SBRT) for non-small cell lung cancer (NSCLC).Methods 10 lung SBRT patients were imaged with CTVision before and after irradiation for acquiring and analyzing the three-dimensional set-up error data sets in our department from October 2010 to May 2012.Gross tumor volumes (GTVs) were contoured on pre-and post-SBRT CT sets and combined for generating internal gross tumor volumes (IGTVs).Planning target volume (PTV) margin was calculated,and IGTVs and PTVs were compared for off-line verification of accuracy of SBRT.A paired t-test statistical analysis was conducted with the datasets using SPSS 17.0.Results 80 CT image sets were totally obtained.Setup errors was significant difference before and after radiotherapy in the left-right,superior-inferior and anterior-posterior directions,that were (-0.10±1.30) mmand (-0.15±1.31) mm (P=0.720),(0.18±1.32) mm and (0.18±1.43) mm (P =1.000) and (-0.08 ± 1.19) mm and (-0.13 ± 1.18) mm (P =0.750),respectively.IGTVs of ten patients were smaller than corresponding PTVs (13.53 cm3 and 37.84 cm3,P =0.000).Conclusion Accuracy and safety of SBRT could be verified by imaging with CTVision before and after delivery for non-small cell lung cancer.

OBJECTIVETo investigate the feasibility of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) using hybrid internal fixation of pedicle screws and a translaminar facet screw for recurrent lumbar disc herniation.
METHODSFrom January 2010 to December 2011, 16 recurrent lumbar disc herniation patients, 10 male and 6 female patients with an average age of 45 years (35-68 years) were treated with unilateral incision MIS-TLIF through working channel. After decompression, interbody fusion and fixation using unilateral pedicle screws, a translaminar facet screw was inserted from the same incision through spinous process and laminar to the other side facet joint. The results of perioperative parameters, radiographic images and clinical outcomes were assessed. The repeated measure analysis of variance was applied in the scores of visual analogue scale (VAS) and Oswestry disablity index (ODI).
RESULTSAll patients MIS-TLIF were accomplished under working channel including decompression, interbody fusion and hybrid fixation without any neural complication. The average operative time was (148 ± 75) minutes, the average operative blood loss was (186 ± 226) ml, the average postoperative ambulation time was (32 ± 15) hours, and the average hospitalization time was (6 ± 4) days. The average length of incision was (29 ± 4) mm, and the average length of translaminar facets screw was (52 ± 6) mm. The mean follow-up was 16.5 months with a range of 12-24 months. The postoperative X-ray and CT images showed good position of the hybrid internal fixation, and all facets screws penetrate through facets joint. The significant improvement could be found in back pain VAS, leg pain VAS and ODI scores between preoperative 1 day and postoperative follow-up at all time-points (back pain VAS:F = 52.845, P = 0.000;leg pain VAS:F = 113.480, P = 0.000;ODI:F = 36.665, P = 0.000).
CONCLUSIONRecurrent lumbar disc herniation could be treated with MIS-TLIF using hybrid fixation through unilateral incision, and the advantage including less invasion and quickly recovery.

OBJECTIVETo investigate the feasibility and safety of unilateral incision hybrid fixation using pedicle screws and a translaminar screw in minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF).
METHODSFrom January to June 2010, 18 patients with single-level lumbar disc disease were treated with MIS-TLIF under METRx(TM) X-tube. After decompression and fixation using unilateral pedicle screws, a translaminar screw was inserted from the same incision to the other side. The results of perioperative parameters, radiographic images and clinical outcomes were assessed.
RESULTSAll patients underwent MIS-TLIF were accomplished unilateral hybrid fixation without any neural complication. The average operative time was (107 ± 19) min, the average operative blood loss was (62 ± 21) ml, and the average postoperative ambulation time was (21 ± 5) h. The average length of translaminar facets screw was (52 ± 2) mm, and the postoperative images showed all screws penetrate through facets joint. During the follow-up the visual analogue scale and Oswestry disability index scores were significant improved compared with preoperative (F = 42.221 - 259.833, P < 0.01).
CONCLUSIONSBilateral hybrid fixation could be completed through unilateral incision by pedicle screws and a translaminar screw in MIS-TLIF, and the advantage including less invasion, quickly recovery, short operative time, and saving fixation cost.

Methods:
The clinical data of 26 patients diagnosed with irreducible atlantoaxial dislocation complicated by atlantodental bony obstruction were analyzed retrospectively. All patients underwent anterior retropharyngeal atlantodentoplasty, followed by posterior occipitocervical fusion. Details including surgical duration and blood loss volume were recorded. Radiographic data such as the anterior atlantodental interval, O–C2 angle, space available for the cord, clivus–canal angle, and cervical medullary angle, and clinical data including the Japanese Orthopedic Association (JOA) score were assessed. The fusion time of the grafted bone and the development of complications were examined.
Results:
In patients undergoing anterior retropharyngeal atlantodentoplasty, the surgical duration and blood loss volume were 120.1±16.4 minutes and 100.6±33.5 mL, respectively. The anterior atlantodental interval decreased significantly after the surgery (p <0.001). The O–C2 angle, space available for the cord, clivus–canal angle, and cervical medullary angle increased significantly after the surgery (p <0.001). The JOA score during the latest follow-up significantly increased compared with that before the surgery (p <0.001). The improvement rate of the JOA score was 80.8%±18.1%. The fusion time of the grafted bone was 3–8 months, with an average of 5.7±1.5 months. In total, 11 patients presented with postoperative dysphagia and three with irritating cough. However, none of them exhibited other major complications.
Conclusions
Anterior retropharyngeal atlantodentoplasty can anatomically reduce the atlantoaxial joint with a satisfactory clinical outcome in patients with irreducible atlantoaxial dislocation with atlantodental bony obstruction.

Background & Objective: Radiotherapy and temozolomide are the standard therapy for newly diagnosed
glioblastoma multiforme (GBM). However, it is unclear whether adding another agent to the commonly
used radiotherapy-temozolomide (RT + TMZ) benefits newly diagnosed GBM patients. The present
network meta-analysis aimed to assess the efficacy of combining other agents with RT + TMZ for
GBM treatment.
Methods: A comprehensive literature search was conducted on PubMed, EMBASE.com, Web of
Science, and the Cochrane Central Register of Controlled Trials from inception to September 23, 2014,
to include all randomized controlled trials of RT + TMZ-based therapy in GBM patients. Pairwise and
network meta-analyses were performed to compare the therapeutic regimens. Results: Seventeen studies
involving 4,148 patients were identified. The results of pairwise meta-analysis indicated no significant
differences among most comparison groups, except for bevacizumab + RT + TMZ versus RT + TMZ
for progression-free survival (hazard ratio [HR] = 0.71, 95% confidence interval [CI]: 0.59–0.86; P =
0.000) and RT + TMZ versus RT alone for overall survival (HR = 0.71, 95% CI: 0.58–0.88; P = 0.001).
The results of network meta-analysis also showed no significant differences in most comparisons;
however, adverse events were more common among patients receiving additional therapeutic agents
other than RT + TMZ. The ranking probability analysis indicated that bevacizumab + RT + TMZ and
nimustine + cisplatin + RT + TMZ were associated with the best progression-free and overall survival,
but they also caused the most adverse events in GBM patients. RT + bevacizumab + irinotecan had
the highest probability of being the best regimen for minimizing adverse events.
Conclusions: The addition of other targeted agents, particularly bevacizumab and nimustine, to
RT + TMZ could be slightly effective for the treatment of newly diagnosed GBM patients; however,
adverse events remained common.
