RESUMO
To compare two methods of injecting ropivacaine as an intercostal nerve blocker, and for postoperative pain control after video-assisted thoracic surgery (VATS) in lung cancer patients. Methods: From August 2018 to November 2018, 60 patients who had undergone VATS with a diagnosis of lung cancer, were randomly assigned into two groups: control and test. After the surgery, the control group was injected with an intercostal nerve blocker (0.25% ropivacaine) via the inner thorax by the traditional method, and the test group was injected with ropivacaine via the outer thorax by an improved method. The pain scale was evaluated using the Visual Analogue Scale (VAS) and Prince Henry Pain Scale (PHPS) at 12 h (T1), 24 h (T2), 48 h (T3), and 72 h (T4) after the surgery. The dosage of administered morphine and the adverse effects of ropivacaine after surgery were also evaluated. Results: Injecting ropivacaine to the intercostal nerve by means of both, outer and inner thoracic injection showed satisfied analgesia, as evaluated by VAS and PHPS scores, and there were no significant differences between the two methods at any time point of analysis (T1-T4, P>0.05). The dosage of administered morphine and the time with chest tube were similar (P>0.05) between the groups. However, there were a few cases of subpleural hemorrhage in the test group. Conclusions: Intercostal nerve block with ropivacaine by means of both, outer and inner thoracic injection, showed satisfied analgesia, although, outer thoracic injection is more flexible with fewer complications.
RESUMO
Objective To explore the practical effect of pre-hospital prehabilitation strategy in pulmonary tumor patients. Methods A total of 68 patients receiving thoracic surgery in Department of Pulmonary Oncology, Tianjin Medical University Cancer Institute & Hospital, during July 2018 to April 2019, were divided into pre-hospital prehabilitation group (n=34) and control group (n=34), according to the order of outpatient. Patients in control group received routine guidance before thoracic surgery, and those in pre- hospital prehabilitation group received a home- based preoperative intervention. The differences of 6-minute walking distance (6MWD), hospital anxiety and depression score (HADS), forced expiratory volume at the first second (FEV1), forced vital capacity (FVC), postoperative thoracic drainage and complications were compared between the two groups. Results The values of 6MWD, FEV1 and FVC in the pre-hospital prehabilitation group were (611.08±47.13) m, (2.48±0.51) L and (3.43±0.48) L on one day preoperatively, respectively, while in the control group, the values were (520.26±57.33) m, (2.19± 0.38) L and (3.17±0.58) L, respectively, with statistically significant differences, t=7.136, 2.659, 2.014, P<0.05. The values of 6MWD, FEV1 and FVC in the pre-hospital prehabilitation group were (540.27±85.73) m, (2.07±0.46) L and (2.98±0.67) L at 30 days postoperatively, respectively, while in the control group, the values were (488.86±75.04) m, (1.82±0.51) L and (2.42±0.58) L, respectively, with statistically significant differences, t=2.631, 2.122, 3.685, P<0.05. The thoracic drainage of pre-hospital prehabilitation group and control group were (162.35 ± 43.08) ml and (191.42 ± 69.11) ml, respectively, t=2.081, P<0.05. In addition, the occurrence rates of complications such as pulmonary infection, pulmonary atelectasis and arrhythmia were 0.0%(0/34), 2.9%(1/34), 0.0%(0/34) in the pre-hospital prehabilitation group, while those were 2.9%(1/34), 8.8%(3/34), 14.7%(5/34) in the control group, pre-hospital prehabilitation group had a significant reduction in the occurrence of arrhythmia (P<0.05). Conclusions The pre- hospital prehabilitation strategy significantly improve the perioperative functional status and prognosis of lung cancer patients, and reduce the occurrence of postoperative complications to a certain extent, which is worth of being further promoted clinically.

Objective To discuss the operative strategies for cervical spine fracture combined with ankylosing spondylitis and the deformity of cervicothoracic kyphosis.Methods Retrospectively analyzed 21 cases of cervical spine fracture combined with ankylosing spondylitis and the deformity of cervicothoracic kyphosis,who underwent surgeries from January,2007 to August,2014.Twenty males and 1 female were included.Mean age was (48.6±7.5) years (range,36-65 years).The preoperative American Spine Injury Association (ASIA) classification distribution:2 cases of Grade A,6 cases of Grade B,7 cases of Grade C,5 cases of Grade D,and 1 case of of Grade E.The investigative surgical methods including posterior cervical open reduction,internal fixation and bone graft fusion;posterior cervical open reduction/decompression,internal fixation and bone graft fusion;or combined posterior and anterior cervical decompression,bone graft fusion and instrumentation.The operative time and blood loss were recorded,the clinical therapeutic effect was evaluated by visual analogue scale (VAS) score,ASIA grade improvement,cervical curvature (the angle between a line drawn parallel to the inferior endplate of C2 and a line drawn parallel to the inferior endplate of C7 in the lateral plane of an X-ray image) and radiological assessment (including bone graft fusion condition and internal fixation position).Results One case died from severe pulmonary infection and respiratory failure at the 45th day after operation.All the other 20 patients obtained complete follow-up with a mean time of (39.4±8.76) months (range,25-59 months).7 cases received posterior cervical open reduction,internal fixation and bone graft fusion,average operative time was (92.1±5.4) minutes and average blood loss was (96.1+23.7) ml.9 cases received the posterior cervical open reduction and decompression,internal fixation and bone graft fusion,mean operation time was (121.4± 14.0) minutes and blood loss was (250.0±38.9) ml.3 cases experienced combined posterior and anterior cervical decompression,bone graft fusion and fixation,average operative time was (222.4± 14.9) minutes and average blood loss was (354.3+46.7) ml.Mean of VAS scores at the 3th month postoperatively was 2.76±0.46,significantly lower than the preoperatively VAS scores (8.95±0.36).Mean of VAS scores at the 24th month postoperatively was 1.77±0.39,significantly lower than those at the 3th month postoperatively.The neurological function of spinal cord achieved significant improvement after operations and continued recovered gradually in the subsequent follow up.ASIA Classification distribution at the 24th month postoperatively was:0 case of Grade A,0 case of Grade B,3 cases of Grade C,8 cases of Grade D,9 case of Grade E.Mean of the cervical curvature after operation was-7.1°± 1.9°,significantly higher than preoperatively(-13.4°±3.3°) and did not have any loss of Cobb's angles at 24th month after operation.All the surviving cases achieved solid bone graft fusion.Mean bone graft fusion time was 5.8 months (range,4-9 months).There was no internal fixation loose,fracture and dislocation occurred during follow up.Conclusion All procedures can significantly relieve the painful symptoms,effectively restore the normal cervical alignment and stability,and remarkably improve the neural function of the patients suffering cervical spine fracture combined with ankylosing spondylitis and the deformity of cervicothoracic junction kyphosis.
RESUMO
Objective: The expression of WNT5A is associated with aggressive tumor biology and poor clinical outcomes of various types of cancer. However, its function in the cell migration of small cell lung cancer (SCLC) should be elucidated. Methods:The expres-sion of WNT5A in SCLC and normal lung tissues was detected by immunohistochemisty. The correlation between the expression and clinical characteristics of WNT5A was analyzed. The function of WNT5A in regulating cell migration was studied in DMS153 cell line in vitro. Small interfering RNA (SiRNA) was used to knock down WNT5A. Wound healing and Transwell tests were used to determine the migration rate of DMS153. The phosphorylated JNK expression was detected by Western blot analysis. Results:The WNT5A expression was higher in SCLC tissues than that of normal lung tissues. WNT5A was correlated with clinical stages, lymph nodes, and distance me-tastasis in SCLC. The high expression of WNT5A was accompanied by abnormal levels of NSE and Pro-GRP. The WNT5A phosphoryla-tion of JNK promoted cell migration in vitro. Conclusion:The expression of WNT5A in SCLC is high and correlated with tumor metasta-sis. The influence of WNT5A/JNK on the cell migration property of DMS153 supports the concept that WNT5A can initiate the cell mi-gration of SCLC, which suggested that WNT5A may be a marker and can be potentially used as an effective therapeutic target for the SCLC metastasis.
RESUMO
Objective:To explore the feasibility and safety of CT-guided hookwire localization of small lung nodule in video-as-sisted thoracic surgery. Methods: Preoperative localization of small lung nodule was performed using the CT-guided hookwire tech-nique, followed by video-assisted thoracic surgery in the wedge resection. The next mode of operation depends on the results of frozen biopsy. Results:Preoperative localization with CT-guided hookwire was performed in 34 patients between February 2012 and March 2014. The diameter of lung nodule ranged from 5 mm to 22 mm. CT-guided hookwire localization was successful in all patients, with a median positioning time of 23 min. Puncture needles were detached from two of the total patients during the surgery, and three other pa-tients showed pneumothorax by CT scan after localization. Conclusion:Preoperative hookwire localization of small lung nodule is an accurate and safe approach to improve the rate of wedge resection in video-assisted thoracic surgery.
RESUMO
Solitary brain metastasis in non-small cell lung cancer (NSCLC) patients was previously considered as Stage IV. Gen-erally, only chemotherapy or radiotherapy rather than surgery was considered the treatment for these patients;hence, achieving the de-sired effect was difficult. In recent years, the treatment benefit for these patients significantly increased. Several patients were even pro-vided the chance of being cured through standardized and individualized treatment by a multiple disciplinary team (MDT). This article introduces two solitary brain metastasis patients with NSCLC who were treated by MDT in Tianjin Medical University Cancer Institute and Hospital. This article aims to explore a complete set of diagnostic and treatment practices for the benefit of more patients.
RESUMO
Objective:To comprehensively investigate the prognostic significance of nodal skip metastasis and lobe-specific me-tastasis for patients with IIIa-N2 non-small-cell lung cancer (NSCLC). Methods:A total of 218 completely resected pN2-NSCLC cases with systematic lymph node dissections from 2008 to 2009 at Tianjin Medical University Cancer Hospital were enrolled. Mediastinal lymph node metastasis was subdivided into continuous metastasis and skip metastasis according to whether N1 lymph nodes were in-volved. Mediastinal lymph node metastasis was also classified into extensive metastasis and lobe-specific metastasis on the basis of whether the lymph nodes involved were within or beyond lobe-specific regions. Overall survival (OS) and disease-free survival (DFS) were compared. Results:For the whole cohort, 5-year OS was 21.6%and 5-year DFS was 16.8%. The 5-year OS for patients with skip metastasis or continuous metastasis were 37.6%and 22.0%, respectively (P=0.008). The 5-year DFS of patients with skip metastasis or continuous metastasis were 29.1%and 15.0%, respectively (P=0.022). The 5-year OS of patients with lobe-specific metastasis and ex-tensive metastasis were 38.3%and 20.4%, respectively (P=0.005). The 5-year DFS of patients with lobe-specific metastasis and exten-sive metastasis were 28.4%and 15.1%, respectively (P=0.009). According to the two patterns, patients were subdivided into three sub-groups:Group A (presence of both skip metastasis and lobe-specific metastasis), Group B (presence of skip metastasis only or lobe-spe-cific metastasis only), and Group C (presence of non-skip metastasis and non-lobe-specific metastasis). The 5-year OS of the three sub-groups were 47.1%(Group A), 28.1%(Group B), and 16.6%(Group C) (P=0.001), and the 5-year DFS of these subgroups were 35.2%(Group A), 20.8%(Group B), and 11.2%(Group C), respectively (P=0.002). Multivariate analysis demonstrated that the combined pat-tern was an independent prognostic factor for both OS and DFS. Conclusion:This combined pattern of lymph node metastasis was a strong prognostic factor for IIIa-N2 NSCLC. This pattern should be considered when predicting prognoses and during the selection of patients that will receive postoperative treatments.
RESUMO
Objective To analyze the factors affecting the efficacy of postoperative radiotherapy (PORT) in node-positive non-small cell lung cancer (NSCLC). Methods 480 patients with stage N_1-N_2 NSCLC after radical surgery were retrospectively reviewed. Of them, 267 patients received adjuvant chemotherapy and 121 received PORT. All patients were grouped based on the N stage, tumor size and lymph node positive ratio (the percentage of positive lymph nodes from the detected lymph nodes, LNPR). Group 1 included patients with tumor size ≤3 cm and LNPR ≤33%, group 2 was tumor size > 3 cm or LNPR > 33%, and group 3 was tumor size > 3 cm and LNPR > 33%. The endpoints were the local recurrence free survival (LRFS) and overall survival (OS). Kaplan-Meier method and Cox's proportional hazards regression model were used for the statistic analyses. Results PORT improved the overall survival only in patients with N_2 disease. Both tumor size and LNPR significantly influenced the efficacy of PORT. The 5-year LRFS for patients with vs. without PORT in the group 1, 2 and 3 were 55% vs. 60% (χ~2 = 0.03,P-0.869), 42% vs. 50% (χ~2 =0.31,P=0.547),and 62% vs. 52% (χ~2=4.25,P=0.036), respectively;and the corresponding OS were 22% vs. 50% (χ~2 = 1.65 ,P =0. 199), 26% vs. 22% (χ~2= 0. 13,P=0.786) and 42% vs. 16% (χ~2= 15.33,P=0.000), respectively. Conclusions Tumor size and LNPR significantly impact the efficacy of PORT . For patients with stage N_2 NSCLC , PORT could improve local recurrence free survival and overall survival when tumor size > 3 cm and LNPR >33%.

RESUMO
<p><b>BACKGROUND</b>Sleeve recestion for lung cancer can get similar tumor and lymph node resection rate as pneumonectomy, with less influence on pulmonary function and much improvement of quality of life. The aim of this study is to compare the 5-year survival and complications of sleeve resection and pneumonectomy for lung cancer.</p><p><b>METHODS</b>Survival analysis was used to investigate the 5-year survival of 173 patients undergoing sleeve resection and 435 patients undergoing pneumonectomy from January 1990 to December 2000. Their complication and perioperative motality were also analyzed.</p><p><b>RESULTS</b>The overall 5-year survival for sleeve resection and pneumonectomy was 42.3% and 30.9%, respectively (P=0.007). 5-year survival of right lung sleeve resection was better than that of left lung [P=0.004 (N0), 0.025 (N1), 0.042 (N2)]. In left lung cancer patients without nodal involvement, the survival after sleeve resection was better than that after pneumonectomy. There was no survival difference between N1 and N2 lung cancer patients. Survival was not significantly different for bronchoplasty and pulmonary arterioplasty and pneumonectomy. The incidence rate of pneumonia and arrhythmia for sleeve resection was less than those for pneumonectomy (P=0.0019), and no significant difference of mortality was observed between the two groups.</p><p><b>CONCLUSIONS</b>In lung cancer patients suitable for sleeve resection or pneumonectomy, sleeve resection should be performed for right lung cancer and left lung cancer of stage I. Bronchoplasty and pulmonary arterioplasty don't prolong the survival of lung cancer patients compared with pneumonectomy.</p>
