ABSTRACT
Objective@#To evaluate the efficacies of different treatment modalities for patients with advanced hypopharyngeal cancers, which were treated by induction chemotherapy and surgery combined with radiotherapy or concurrent chemoradiotherapy.@*Methods@#A retrospective analysis was performed on the complete clinical and follow-up data of 92 patients with pathologically confirmed hypopharyngeal squamous cell carcinoma treated at Liaoning Tumor Hospital from January 2011 to December 2016. The tumor clinical staging was as follows: stage Ⅱ in 3 cases, stage Ⅲ in 33 cases, and stage Ⅳ in 56 cases. All patients underwent electronic esophagoscopy before treatment to remove esophageal cancer patients. The patients and their families chose voluntarily their desirable treatments from following modalities: A. Induction chemotherapy sensitivity plus radiotherapy or concurrent chemoradiotherapy, otherwise induction chemotherapy insensitivity plus surgical treatment; B. Surgical treatment plus radiotherapy or concurrent chemoradiotherapy, with drugs to control adverse reactions. The Kaplan-Meier method was used to calculate OS rates and Log-rank test was used to compare the OS rates between the two groups. Crosstabs was used to compare the difference in the 1, 3 and 5-year OS rates and the organ preservation rates between group A and group B, using chi-square test as non-parametric test.@*Results@#Fifty-two patients were enrolled in group A, after 2 cycles of induction chemotherapies with TPF(docetaxel, cisplatine, 5-Fu), there were 46 sensitive cases with primary lesions reduced by ≥50% (including 5 cases with tumor complete response) and 6 insensitive cases with primary lesions reduced by <50%. The 46 sensitive patients were treated with radiotherapy or concurrent chemoradiotherapy according to their physical conditions and 6 insensitive patients treated with surgery, including total laryngectomy for 5 cases and partial laryngectomy for one case. The 1, 3, and 5-year OS for 52 patients in group A were 91.93%, 49.59%, and 37.20%, respectively, with an organ preservation rate of 90.4% (47/52). Forty patients were enrolled in group B, including 33 cases with total laryngectomy and 7 cases with partial laryngectomy. The 1, 3, and 5-year OS for 40 patients in group B were 77.50%, 57.86% and 43.41%, respectively, with an organ preservation rate of 17.5%(7/40). The 1-year OS of group A was higher than group B (χ2=4.349, P<0.05), and there was no statistical difference in the 3-year or 5-year OS between two groups. The organ preservation rate of 90.4% (47/52) in group A was higher than that (17.5%, 17/40) in group B, with a significant difference (χ2=49.539, P<0.001).@*Conclusions@#The clinical effectiveness for advanced hypopharyngeal carcinoma is still poor, and surgical treatment is still the main treatment method. According to the results of induction chemotherapy, radiotherapy, concurrent chemoradiotherapy or surgical treatment can be chosen, and ideal and feasible treatment modalities may improve the quality of life of patients, with high OS rate laryngeal preservation rate.
ABSTRACT
Objective@#To evaluate the efficacy of gastric pull-up and complex laryngotracheal flap in reconstruction for circumferencial defects after resection of hypopharyngeal and cervical esophageal cancers.@*Methods@#A total of 163 cases (152 males, 11 females) with circumferencial defect after resection of hypopharyngeal and cervical esophageal cancers received reconstructive surgeries by gastric pull-up (42 cases) and complex laryngo-tracheal flaps (121 cases), of them 115 cases simultaneously underwent unilateral neck dissection and 20 cases had bilateral neck dissection. Postoperative radiotherapy was used in 67 cases, with a dosage of 40-60 Gy.@*Results@#There were 127 (77.9%) cases with positive metastatic lymph nodes. Of 42 patients with gastric pull-up reconstruction, 39 cases (92.8%) recovered the function of oral swallowing after operation, and 8 cases with cervical esophageal cancer recovered the functions of oral swallowing and speech after gastroesophageal anastomosis reconstruction. There were 3 (7.1%) cases died of surgery and 8 cases with surgical complications. Reconstruction of upper digestive tract with combined laryngotracheal flap was successful in all 121 cases, with recovered oral swallowing function after operation. No patient died of surgery but 24 cases had complications, mainly pharynx skin fistula or wound infection, which were cured by conservative treatments. The 1-, 3- and 5-year survival rates for 163 patients were 69.8%, 50.5% and 34.3%, respectively. The independent factors for prognosis included T4 (P<0.001) and N+ (P=0.042).@*Conclusions@#The complex of laryngotracheal flap with pectoralis major myocutaneous flap is suitable for most advanced hypopharyngeal cancer after resection of the tumor and reconstruction of circumferencial defect. It is simple technology, low and slight complication rate. The minority is not suitable for the application of pectoralis major myocutaneous flap can be used instead of free anterolateral thigh flap. Gastric pull-up for reconstruction of upper digestive tract is suitable for most patients with cervical esophageal cancer and hypopharyngeal carcinoma invading the cervical esophagus who are not suitable for laryngotracheal flap reconstruction, with good swallowing function after surgery. However, it is prudent to choose operative indications because of serious surgical trauma and risks for complications.
ABSTRACT
Objective To explore the clinical efficacy and indications of kyphoplasty with movement and secondary en?largement of balloon for the compression fracture of vertebral body with ruptured posterior wall. Methods A retrospective analy?sis was carried out on the data of 29 patients (10 males, 19 females;age range:55-86 years old;mean age:71 years old;29 verte?bral bodies in total) who suffered from compression fracture of the thoracolumbar spine and below, and underwent kyphoplasty through the movement and secondary enlargement of balloon within the vertebral body and were followed up from January 2011 to November 2014. These patients had backache, accompanied by lowered support, limitation of movement, no symptom of nervous lesion on both lower extremities and no past history of balloon kyphoplasty. All fractured vertebral bodies were at T 11 or below, in?cluding 1 case at T11, 4 cases T12, 11 cases L1, 9 cases L2 and 4 cases L3. The causes of injury included fall (19 cases), car accident (8 cases) and unknown reasons (2 cases). All patients underwent kyphoplasty with the movement and secondary enlargement of bal?loon within the vertebral body. Photos were taken immediately after the surgery, at 1 month, 3 months, 6 months and 12 months, and these patients were assessed and analyzed in terms of vertebral height, Cobb angle, visual analogue score (VAS) and Oswestry disability index (ODI). Results The operation time (including the formation and solidification of bone cement) of 29 patients was 40 to 65 min and the mean time was 55 ± 7 min;the blood loss during operation was 2 to 15 ml and the mean blood loss was 5 ± 2 ml;the injected volume of bone cement was 2.5-7.5 ml and the mean volume was 5.5±0.5 ml. Post?operative pain was relieved and ambulation was performed under the protection of lumbar orthosis brace. Statstical analysis was conducted on VAS, ODI, vertebral height and Cobb angle before operation and at 1 month, 3 months, 6 months and 12 months after operation, showing statistically significant differences. X ray examination found that there was no alternation or displacement of bone cement location, and no change in vertebral morphology, the vertebral height and cobb angle remained the post?operative status, and posterior wall rupture of the vertebral body was recovered well. CT revealed that the morphology of bone cement was irregular and closely integrated with bone substance, and no cavity or fissure was seen. Conclusion Kyphoplasty with movement and secondary enlargement of bal?loon within the vertebral body has a good, definite clinical efficacy in treating compression vertebral fracture with incomplete pos?terior wall of the vertebral body without obvious displacement of fractured bone and symptom of nervous lesion on both lower ex?tremities. This surgery is easy to operate, and has an immediate analgesic effect, which could recover vertebral height as well as re?duce kyphosis deformity and improve patient’s prognosis.
ABSTRACT
Objective To investigate the selection of operative method and peri operative managements for osteoporotic femoral intertrochanteric fracture in elderly patients aged over 75 years.Methods A total of 132 consecutive patients aged 75-91 years with osteoporotic intertrochanteric fractures from July 2009 to July 2012 were retrospectively analyzed.47 patients were treated with dynamic hip screw (DHS group),44 patients with proximal femoral nail anti-rotation (PFNA group) and 41 patients with Gamma Ⅲ nail (Gamma Ⅲ group).The peri-operative managements,operation circumstance,the time for fracture union,postoperative complications and the degree of functional recovery were analyzed and compared between the 3 groups.Results The mean surgical time was shorter in Gamma Ⅲ nail and PFNA groups than in DHS group [(68.7±9.1) min,(80.5±11.3) min vs (112.2±18.4) min,both P＜0.01].The mean blood loss was less in the Gamma Ⅲ nail and PFNA groups than in DHS group[(156.9±18.5) ml,(183.4±21.3) ml vs (296.2±29.6) ml,both P＜0.01].The mean time for fracture healing was shorter in Gamma [Ⅲ nail and PFNA groups than inDHSgroup [(12.6±2.4) weeks,(13.1±2.4) weeks vs (15.3±3.2) weeks,both P＜ 0.05],and it has no obvious difference between Gamma Ⅲ nail and PFNA groups (P＞0.05).There were significant differences in postoperative complications between Gamma Ⅲ nail,PFNA groups and DHS group (2 cases,3 cases vv 11 cases,P＜0.05,respectively).The mean Harris hip score had no significantly difference among DHS,Gamma Ⅲ nail and PFNA groups (87.4±11.6,90.2±13.0 vs 88.9±12.3,both P＞0.05).Conclusions The 3 operative methods for stable intertrochanteric fracture are feasible and effective in elderly patients,but for unstable intertrochanteric fractures,the treatment with Gamma Ⅲ nail and PFNA has advantages.
ABSTRACT
Objective To evaluate the clinical effectiveness of double balloon dilation in percutaneous kyphonplasty on curing vertebral?compression fractures. Methods From January 2009 to September 2013, 84 patients (94 vertebral bodies) with vertebral compression were treated by percutaneous kyphonplasty. All were fresh fractures and were injured or obvious low back pain 1 month, accompanied by local tenderness, kowtow attack painful, lumbar mobility, but no lower extremity injury numbness, activities and defecation disorders. After randomization, the double balloon dilation in percutaneous kyphonplasty method was used to treat 44 patients (49 vertebrae). In the process of performing percutaneous unilateral pedicle puncture and balloon dilata?tion of the vertebral body, the balloon has been moved some distance in the vertebral body. Then completed the perfusion of bone cement, vertebral body forming. 40 cases (45 vertebrae) were used conventional unilateral percutaneous kyphonplasty to vertebtal compression fractures. Recorded the operation time, amount of bleeding, bone?cement injection volume. Used visual analogue scale (VAS), the height of the vertebral body and Cobb angle to evaluated the curative effect. Results All 84 patients completed the operation, follow?up time was 22 months (18-24 months). In two mobile open expansion group, the operation time was about 48 min. The amount of bleeding was 8-15 ml. The average bone?cement injection volume was 5.1 ml. No patients quit the study and no bone cement?leakage cases or other side effects were observed , and no clinical accidents occurred. In a single stretching group, 40 cases (45 vertebrae) completed conventional vertebroplasty, the time of 44 min, bone cement average injection rate 3.2 ml, bleeding 10-15 ml. In two mobile open expansion group, the VAS score was 8.5 points, the height of the vertebral body height was 2.1cm, and the Cobb angle was 34°. After operation, the VAS score 2.9 points, the height of the vertebral body 2.8 cm, and Cobb 20° . In the other group, the pain was significantly relieved and the relief was satisfactor after operation.Vertebral height of 2 cm turned to the last follow?up of 2.4 cm. The Cobb angle was 32°, and the last follow?up was 27°. The VAS score, operation time and bleeding volume of the two groups were not statistically significant, and a statistically significant difference of the average bone ce?ment injection volume, postoperative vertebral height and cobb angle improved with statistical significance. A single open group were 2 cases of bone cement leakage and leakage, 1 cases of bone cement tail, the complication rate was 5.6%. Conclusion The application of double balloon dilation in percutaneous kyphonplasty to vertebral?compression fractures improve relocation of verte?bral compression fractures, increase recovery of vertebral height, and more effectively strengthen and stiffen pathological vertebral bodies, while improving kyphosis. Moreover, it can reduce pressure during bone?cement injections, minimizing the chance of over?flow and leakage, as well as the related side effects, but it will also result in an increase of bone cement?injection volume.
ABSTRACT
Objective To investigate the effect of high volume hemofiltration (HVHF) on expression of miRNA-146 in peripheral blood mononuclear cells in posttraumatic sepsis patients and its therapeutic mechanism.Methods Twenty-five cases of posttraumatic sepsis were included as HVHF group.Another 25 age-and gender-matched traumatic sepsis patients with similar APACHE-Ⅱ who received no HVHF treatment for some reasons were used as controls.Therapeutic measurements were the same of the two groups except for HVHF.At 0-,6-,12-,24-and 48-hour time points,the peripheral blood mononuclear cells were isolated from patients of both groups to detect level of miRNA-146.Peripheral blood mononuclear cells isolated at 24 hours were incubated with lipopolysaccharide (LPS) in vitro.At hours 4,8,12,24 and 48 after incubation,level of miRNA-146 in mononuclear cells was determined and levels of TNF-α,IL-6,and IL-10 in the substrate was detected by ELISA.Results (1) Level of miRNA-146 in HVHF group was decreased significantly over time as compared with that in sepsis group;(2) Before incubation and at 4-and 8-hour after incubation,miRNA-146 level was lowered significantly in HVHF group as compared with that in sepsis group.After LPS stimulation,mononuclear cell also presented a stronger inflammatory response in HVHF group than in sepsis group.Conclusions HVHF provides a definite effect on immune function recovery and a significant improvement in prognosis.Moreover,HVHF may attenuate the impact of miRNA-146 on mononuclear cell inflammatory factor release and enhance the cell ability to respond to external stimuli again via down-regulating miRNA-146,as may be one of the therapeutic mechanisms of HVHF for posttraumatic sepsis.
