ABSTRACT
Objective:To investigate the clinical value of early gastroscopy for patients with hypopharyngeal cancer.Methods:A total of 231 cases of hypopharyngeal cancer diagnosed and treated in the First Affiliated Hospital of Xiamen University from January 2010 to December 2014 were included in the retrospective analysis. The 5-year survival rate of hypopharyngeal cancer and patients accompanied with synchronous esophageal cancer (including early and advanced esophageal cancer), as well as the detection rate of synchronous esophageal cancer by gastroscopy and systemic PET-CT examination were statistically analyzed.Results:The 5-year survival rate of hypopharyngeal cancer was 38.96% (90/231). The 5-year survival rates of 62 patients accompanied with synchronous esophageal cancer and 169 patients without were 27.42% (17/62) and 43.20% (73/169), respectively, with statistic difference ( χ2=4.747, P=0.029). The 5-year survival rate of 49 patients accompanied with synchronous early esophageal cancer was 30.69% (17/49). Among the 13 patients with synchronous progressive esophageal cancer, none had a survival period of 5 years, which was significantly different compared with the patients with synchronous early esophageal cancer ( P=0.013). The detection rates of synchronous esophageal carcinoma by gastroscopy and by systemic PET-CT were 26.84% (62/231) and 14.29% (33/231), respectively, with statistic difference ( χ2=11.14, P<0.01). The detection rates of synchronous early esophageal carcinoma by gastroscopy and by systemic PET-CT were 21.21% (49/231) and 8.66% (20/231), respectively, and the difference was also statistically significant ( χ2=14.328, P<0.01). Conclusion:Hypopharyngeal cancer accompanied with synchronous esophageal cancer is of high risk, which affects the survival rate of patients. Early gastroscopy in hypopharyngeal cancer patients can significantly improve the detection rate of synchronous esophageal cancer, which helps to design individualized regimen to improve the survival rate of patients.
ABSTRACT
Objective:To study the efficacy of dental floss traction-assisted endoscopic submucosal dissection (ESD) for gastric angle mucosal lesions.Methods:Data of 127 patients with gastric angle mucosal lesions admitted to the endoscopic center of the First Affiliated Hospital of Xiamen University from January 2015 to December 2018 were retrospectively analyzed. According to the surgical methods, patients were divided into the dental floss traction-assisted ESD group (the traction group, n=51) and the traditional ESD group (the traditional group, n=76). The 41 fibrosis cases were further divided into the traction group (n=23) and the traditional group (n=18). The operation time, en block resection rate, curative resection rate and the incidence of adverse events such as bleeding, muscle layer injury and perforation were compared between the two groups.Results:There was no significant difference in age, sex, lesion size or morphology between the traction group and the traditional group ( P > 0.05). The operation time of the traction group was significantly shorter than that of the traditional group (65.4±36.5 min VS 103.5±43.2 min, P=0.012). The en block resection rate was higher in the traction group [100.00% (51/51) VS 90.79% (69/76), P=0.026], and the curative resection rate was higher too [94.12% (48/51) VS 81.58% (62/76), P=0.042]. The incidences of muscular layer damage [5.88% (3/51) VS 25.00% (19/76), P=0.010] and intraoperative bleeding [47.06% (24/51)VS 82.89% (63/76), P=0.010] were lower in the traction group. Perforation occurred in two patients (2.63%) of fibrosis in the traditional group; no perforation occurred in the traction group. There was no significant difference in the perforation incidence ( P=0.243). In the cases of fibrosis, the operation time of the traction group was significantly shorter compared with that of the traditional group (81.4±29.3 min VS 119.3±37.6 min, P=0.010). The en block resection rate and curative resection rate were also higher in the traction group [100.00% (23/23) VS 72.22% (13/18), P=0.007; 95.65% (22/23) VS 72.22% (13/18), P=0.035]. The incidences of muscular layer damage [8.70% (2/23) VS 72.22% (13/18), P=0.001] and intraoperative bleeding [78.26% (18/23) VS 100.00% (18/18), P=0.035] were lower in the traction group. Conclusion:The dental floss traction-assisted ESD is safe and effective for gastric angle mucosal lesions and fibrotic lesions, with shorter operation time, higher curative resection rate and lower incidence of adverse events.
ABSTRACT
Objective@#To investigate the clinical symptoms, imaging features, pathologic manifestations and diagnosis of tracheobronchopathia osteochondroplastica (TO).@*Methods@#The clinical data, imaging and pathologic features and outcome of 18 TO patients diagnosed at the First Affiliated Hospital of Zhengzhou University from August 2011 to August 2018 were collected and analyzed.@*Results@#The 18 TO patients included 10 males and 8 females; patients′ age range was 31 to 64 years (mean 52 years). Six patients (6/18) were smokers. The main presenting clinical symptoms included cough in 15 cases, expectoration in eight cases (8/18), hemoptysis in five cases (5/18), chest tightness in four cases, wheezing in three cases and chest pain in two cases. The time interval between the initial symptoms and diagnosis was 1.5 to 360.0 months, and the average time interval was 45.2 months. Blood calcium and phosphorus were normal in 18 patients (18/18). Chest X-ray showed no direct evidence of TO. Six patients (6/18) showed irregular changes in the trachea or bronchial wall by chest CT scan. Three patients (3/18) had mild ventilatory obstruction. TO was classified as: 10 cases (10/18) were scattered type, seven cases (7/18) were diffuse type and one case (1/18) was confluent type. Epithelial squamous metaplasia, submucosal cartilage, submucosal ossification and hematopoietic bone marrow within the ossified areas were the characteristic histopathologic findings of TO.@*Conclusions@#TO is a rare benign disorder that shows atypical presentation. CT scan is insensitive, the histopathology shows submucosal cartilage or ossification. TO should be diagnosed by comprehensive consideration of clinical symptoms, imaging and pathology.
ABSTRACT
Objective@#To investigate the clinicopathological features and prognostic indicators of primary pulmonary adenoid cystic carcinoma.@*Methods@#Fifty-nine cases of primary pulmonary adenoid cystic carcinoma were collected from August 2011 to December 2017 at the First Affiliated Hospital of Zhengzhou University. All cases were retrospectively studied by hematoxylin-eosin staining and immunohistochemistry. The clinicopathological features were reviewed and patient survival analysis was performed using Kaplan-Meier method and Cox regression model. Status of epidermal growth factor receptor (EGFR), KRAS, BRAF genes was analyzed in 15 of the 59 study cases.@*Results@#Among 59 cases, there were 25 males and 34 females with male to female ratio of 1.0 to 1.4. The patient age ranged from 29 to 81 years with a mean age of 55 years. The tumor max diameters ranged from 1.0 to 9.6 cm with an average diameter of 2.8 cm. Fifteen (25.4%) patients were smokers while 44 patients (74.6%) were non-smokers. Tumors predominantly occurred in the trachea (28/59,47.5%), the left main bronchus (7/59,11.9%) and the right bronchus (5/59,8.5%). Grossly, the tumors were well circumscribed, greyish-white nodules. Microscopically the tumor cells were small and uniform, and arranged in tubular, cribriform, and solid patterns. Immunohistochemistry showed that the tumor cells were positive for CK7, S-100 protein, Sox-10, CD117 and p63. TTF1 was only positive in 2 cases and Ki-67 index ranged from 3% to 40%. Eighteen cases (30.5%) were gradeⅠ, 26 cases (40.1%) grade Ⅱ, and 15 cases (25.4%) grade Ⅲ. Overall, 39 cases (66.1%), 7 cases (11.9%), 10 cases (16.9%), and 3 cases (5.1%) were at stages Ⅰ, Ⅱ, Ⅲ, and Ⅳ, respectively. Twenty-three patients (39.0%) received surgical therapy, 3 patients (5.1%) surgery combined with radiotherapy, 9 patients (15.2%) surgery combined with chemotherapy, and 24 cases (40.7%) chemotherapy only. No mutation of EGFR, KRAS and BRAF was detected in all 15 tested cases. The overall survival rate at the first, third and fifth years was 94.9%, 86.4% and 84.7%, respectively. Prognostic analysis showed that patient′s age and tumor size were statistically associated with the survival (P<0.05).@*Conclusions@#Majority of the patients with primary pulmonary adenoid cystic carcinoma are at an early clinical stage with a favorable prognosis. The size of the tumor and the age of the patients are independent prognostic indicators.
ABSTRACT
Objective@#To investigate the clinicopathological features, diagnosis and differential diagnosis of pulmonary extranodal NK/T-cell lymphoma, nasal type (ENKTL-NT).@*Methods@#Eleven cases of newly diagnosed (10 puncture biopsies and 1 transbronchial biopsy), previously untreated pulmonary ENKTL-NT were collected at the First Affiliated Hospital of Zhengzhou University, from August 2013 to November 2018. The clinicopathological features including histomorphology, immunohistochemistry and in situ hybridization were collected and analyzed.@*Results@#Among the 11 cases, 8 were males and 3 were females, with a male to female ratio of 8∶3.The age range was from 30 to 74 years, with an average of 48 years and a median of 43 years. Tumors involved bilateral lung lobes in 8 cases, the upper left lobe in 1 case, lower left lobe in 1 case, and upper right lobe in 1 case. Main clinical symptoms included fever, often accompanied by cough, and bloody sputum in most cases. All cases were stage Ⅳ E. Histological features included scattered or focal aggregates of marked pleomorphic tumor lymphocytes, accompanied by necrosis and heavy admixture of inflammatory cells. In a few cases, diffuse neoplastic lymphocytes or vascular central and destructive infiltrations were seen. Tumor cells in most cases expressed CD3ε, CD3, CD43, CD56, TIA-1, granzyme B, but did not express CD20, CD79a, and CD5. Ki-67 index ranged from 40%to 90%.All cases were positive for EBER by in situ hybridization. Four of five patients died during follow-up with a survival period of only 1 week to 13 months.@*Conclusions@#Pulmonary ENKTL-NT is rare, high grade malignancy with a poor prognosis. Misdiagnosis is common due to lesional necrosis and heterogeneous cell components. Immunohistochemistry and EBER in situ hybridization are essential for accurate diagnosis.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the impacts on the life quality and the effect mechanism in the patients of allergic rhinitis (AR) treated with warm acupuncture in winter and summer.</p><p><b>METHODS</b>Two hundred and forty patients of AR were randomized into a summer and winter acupuncture group, a non-summer and winter acupuncture group and a western medication group, 80 cases in each one. In the two acupuncture groups, Dazhui (GV 14), Fengmen (BL 12), Feishu (BL 13), Pishu (BL 20) and Shenshu (BL 23) were selected. In the summer and winter acupuncture group, the warm acupuncture started at the first day of the three periods of hot season and the first day of the third nine-day period after the winter solstice. The treatment was given once every two days, continuously for 15 times. Totally, 30 treatments were required a year. In the non-summer and winter acupuncture group, the warm acupuncture was applied out of the three periods of the hot season and the third nine-day period after the winter solstice. The treatment was given once every two days and 30 treatments for a year. In the western medication group, cetirizine was taken orally, continuously for 30 days as one session. In the three groups, the treatment for 1 year was taken as one session. The second session started in the next year. Totally, 2 sessions were required. The score of rhinoconjunctivitis quality of life questionnaire (RQLQ) and the level of serum immunoglobulin E (IgE) were compared in the patients' of each group before treatment and in 1 and 2 sessions of treatment.</p><p><b>RESULTS</b>After treatment, the scores of 7 domains, named activities, common complaints, practical problems, sleep, ocular symptoms, nasal symptoms and emotions were all improved as compared with those before treatment, in the patients of the three groups (all P < 0.05). After 2 sessions treatment, the results in the summer and winter acupuncture group were better than those in the other two groups (all P < 0.05), and the results in the non-summer and winter acupuncture group were better than those in the western medication group (all P < 0.05). After treatment, serum IgE level was lower averagely than that before treatment in the three groups (all P < 0.05). After 2 sessions treatment, the result in the summer and winter acupuncture group was lower than that in the other two groups (both P < 0.05), and the result in the non-summer and winter acupuncture group was lower than that in the western medication group (P < 0.05). After treatment, the total effective rate was 92.3% (72/78) in the summer and winter acupuncture group, better than 80.5% (62/77) in the non-summer and winter acupuncture group and 69.7% (53/76) in the western medication group (both P < 0.05).</p><p><b>CONCLUSION</b>The warm acupuncture in both summer and winter achieves the definite efficacy on AR and the effect mechanism is relevant with reducing serum IgE level.</p>

<p><b>OBJECTIVE</b>To compare the difference in clinical efficacy on bronchial asthma at chronic persistent stage between acupuncture for warming yang and benefiting qi and seretide.</p><p><b>METHODS</b>One hundred and eighty patients of bronchial asthma at chronic persistent stage were randomized into an acupuncture group and a western medication group, 90 cases in each one. In the acupuncture group, acupuncture for warming yang and benefiting qi was applied at Dazhui (GV 14), Feishu (BL 13), Danzhong (CV 17), Dingchuan (EX-B 1), Jianshi (PC 5), Zhigou (TE 6), Taixi (KI 3) and Zusanli (ST 36), once every two days. In the western medication group, inhalation therapy with seretide was applied, 1 to 2 inhalations each time, twice a day. The treatment for 20 days was as one session in the two groups, at the intervals of 2 days after each session. Four sessions of treatment were required. The immune function indices were observed before and after treatment in the patients of two groups, named immunoglobulin IgG, IgM and IgE; peripheral T lymphocytes (CD3+), helper T lymphocytes (CD4+), inhibitory T lymphocytes (CD8+) and the ratio of CD4+ and CD8+; as well as the pulmonary ventilation function indices, named maximum pulmonary expiratory flow (PEF), forced expiratory volume in one second (FEV1) and forced vital capacity (FVC). The clinical efficacy was compared between the two groups.</p><p><b>RESULTS</b>The total effective rate was 93.3% (84/90) in the acupuncture group, better than 88.9% (80/90) in the western medication group (P < 0.05). After treatment, the immune function indices and pulmonary ventilation function indices were apparently improved as compared with those before treatment in the two groups (all P < 0.05). The improvements in the acupuncture group were much more significant (all P < 0.05).</p><p><b>CONCLUSION</b>Acupuncture for warming yang and benefiting qi effectively controls the symptoms of bronchial asthma at chronic persistent stage and improves immune and pulmonary functions. The efficacy is better than that of seretide.</p>
