ABSTRACT

Objective: To analyze and evaluate the results of endoscopic screening for upper digestive cancer in Danzhou city of Hainan, China. Methods: Totally 300 8 subjects aged from 40 to 69 years old were selected by cluster sampling method for screening of upper digestive tract cancer in Danzhou from 2015 to 2017. Results: In total, 13 cases (0.43%) of high grade intraepithelial neoplasia and cancer were detected. The detection rate of esophageal cancer, cardia cancer and gastric cancer was 0.07% (2 cases), 0.07% (2 cases) and 0.30% (9 cases), respectively. The diagnosis rate of early cancer was 92.31% (12 cases) and the treatment rate was 46.15% (6 cases). Conclusion: Endoscopic Screening is an effective way to detect precancerous lesions and early cancer. The detection rate in Danzhou is lower than the national average. Improving the professional and management ability of screening project team, mastering the incidence and mortality trend of upper digestive tract cancer, is key to the implementation and evaluation of the project of early diagnosis and treatment of upper digestive tract cancer.

ABSTRACT

Objective@#To evaluate the role of combination of multiple MRI sequences in the differential diagnosis of esophagus cancer and to assess the accordance among radiologists with different experience.@*Methods@#Thirty-fifty patients underwent conventional MRI including T2 weighted (T2) sequences, gadolinium fat-suppressed T1 weighted sequences (post-contrast T1), and DWI sequences. Three radiologists with different experience determined the possibility of local recurrence (LR) on T2, T2+post-contrast T1, T2+DWI, and T2+post-contrast T1+DWI. ROC and Kappa were used.@*Results@#In total, 13 patients had LR. On T2WI, the ROC curve (AUC) achieved by the senior,intermediate and junior groups were 0.701,0.407,and 0.584, respectively.Compared with simple T2WI sequences, DWI and T1 Gd significantly improved the AUC value for the intermediate radiologist. The great difference was observed between radiologists of different experience (Kappa coefficient was from 0.227 to 0.884). Combination of multiple sequences significantly reduced the diagnostic differences between radiologists with different experience for the senior radiologists particularly.@*Conclusions@#The addition of DWI and T1 post-contrast MRI increased diagnostic ability for LR of esophagus cancer and reduced the diagnostic differences between radiologists with different experience compared to T2WI.

ABSTRACT

The discovery of microRNA (miRNA) has opened up a new train of thought for the diagnosis and treatment of esophagus cancer.let-7 is one of the most widely research of miRNA.In a variety of tumors,the expression of let-7 is down-regulated.let-7 can play the role of tumor suppressor gene by targeting to high mobility group A2 (HMGA2) and inhibit the cell proliferation.Recent studies have shown that the lower the degree of differentiation of cells,let-7 expression level is lower.It is expected as a symbol of poorly differentiated tumors.In addition,let-7 and esophagus cancer's radiation and chemotherapy sensitivity are closely related.

ABSTRACT

Objective@#To compare the extent of lymphadenectomy and postoperative complications between Ivor-Lewis procedure and left sided thoracotomy in patients with Siewert type Ⅱ adenocarcinoma of the esophagogastric junction (AEG).@*Methods@#The clinical data of 101 patients with Siewert type Ⅱ EG who received surgical treatment between January 2014 and September 2015 in the Department of Esophageal Cancer, Tianjin Medical University Cancer Hospital were analyzed retrospectively. These patients were divided into Ivor-Lewis group (IL, n=38) and left- sided thoracotomy group (LT, n=63) according to the operation mode. The number and extent of dissected lymph nodes and postoperative complications were compared between the two groups.@*Results@#The surgical blood loss, length of postoperative stay, anastomotic leakage, pulmonary infection, respiratory failure and complications of incision of the two groups showed no significant differences (P>0.05 of all). The operation time of IL group was 200 min, significantly longer than the LT group (120 min, P<0.05). The number of resected lymph nodes in the IL and LT groups were (20±9) and (13±7), respectively, with a statistically significant difference (P<0.001). Significantly more thoracic lymph nodes (7±5) were harvested in the IL group than in the LT group (2±2, P<0.001), and the number of resected abdominal lymph nodes in the IL and LT groups were (13±8) and (11±7), with a non-significant difference (P=0.157). As regarding the lymph node dissection rate, the IL approach was obviously better than the LT approach in the following lymph node stations: superior mediastinal nodes, subcarinal nodes, left hilar nodes, right hilar nodes, middle thoracic paraesophageal nodes, lower thoracic paraesophageal nodes, lymph nodes along the common hepatic artery, and lymph nodes along the splenic artery(P<0.05 for all).@*Conclusions@#The Ivor-Lewis procedure achieves better thoracic and abdominal lymph node dissection, and does not cause more postoperative complications than the left-sided thoracotomy in patients with Siewert type Ⅱ AEG. However, these findings need to be confirmed by large-scale randomized clinical trial in the future.

ABSTRACT

Objective To evaluate the efficacy of salvage radiotherapy for supraclavicular lymph node metastasis ( SLNM) after initial treatment in patients with esophageal cancer. Methods A total of 117 patients with SLNM after radical resection for esophageal cancer were enrolled as subjects from 2006 to 2012. All patients received three?dimensional radiotherapy with 1. 8?2. 0 Gy per cycle, 5 cycles a week. The survival rates were calculated using the Kaplan?Meier method and analyzed using the log?rank test. The Cox model was used for multivariate analysis. Results The follow?up rate was 100%. In all the patients, the 1?and 3?year overall survival (OS) rates were 38. 5% and 14. 1%, respectively. The 1?and 3?year OS rates were significantly higher in patients treated with salvage radiotherapy or radiochemotherapy ( n=100) than in patients without any salvage treatment (n=17)(42% vs. 18%,P=0. 008;17% vs. 0%, P=0. 008). The patients treated with radiochemotherapy ( n=32) had significantly higher 1?and 3?year OS rates than those treated with radiotherapy alone (n=68)(59% vs. 34%, 36% vs. 11%, P=0. 002) or without any salvage treatment (n=17)(59% vs. 18%, 36% vs. 0%, P=0. 002). Patients without visceral metastasis (n=80) had significantly higher 1?and 3?year OS rates than those with visceral metastasis ( n=37) ( 44% vs. 27%, P=0. 002;22% vs. 0%,P=0. 002) . Patients with supraclavicular doses of ≥60 Gy in salvage radiotherapy ( n=75) had significantly higher 1?and 3?year OS rates than those with supraclavicular doses of<60 Gy in salvage radiotherapy ( n=25) ( 75% vs. 25%,P=0. 000;24% vs. 8%,P=0. 000) . The multivariate analysis using the Cox model showed that supraclavicular doses of ≥60 Gy, mediastinal metastasis, visceral metastasis, and salvage treatment method were independent factors for survival ( P=0. 001,0. 015,0. 009, 0. 025) . Conclusions Salvage radiotherapy can improve the survival of patients with SLNM in esophageal cancer. Salvage radiotherapy or radiochemotherapy is highly recommended for patients with SLNM alone. A radiation dose of ≥60 Gy in salvage radiotherapy improves survival in patients.

ABSTRACT

ObjectiveTo measure the setup errors with infrared marker-based positioning system (IM-BPS) and electronic portal imaging device (EPID) for patients with esophageal carcinoma and lung cancer and investigate the accuracy and practicality of IM-BPS. MethodsFrom January 2007 to January 2008, 40 patients with esophageal carcinoma and 27 patients with lung cancer received three-dimensional conformal radiotherapy or intensity-modulated radiotherapy, setup errors during the treatment were measured with IM-BPS and EPID, and the data of setup errors were compared with paired t-test and agreement with x2-test. ResultsIt takes 10 - 12 mins to complete the validating for each patient by EPID) system, while IMBPS system only needs 2 -5 mins. The mean setup errors along x, y and z-axis for patients with esophageal carcinoma measured by IM-BPS and EPID were 3.49 mm, 3. 19 mm, 3.31 mm and 4. 03 mm, 3.41 mm, 3.43 mm, respectively. For the patients with lung cancer, the setup errors were 4. 23 mm, 3.51 mm, 3. 39mm and 4. 85 mm, 3. 53 mm, 3.74 mm, respectively. The difference of setup errors meanured by the two systems was within 1 mm for 65% esophageal carcinoma patients ( x2 =51.09, P =0. 000), and 55% lung cancer patients ( x2 =53. 35, P =0. 000).Conclusions The measurement results of setup errors for patients with esophageal carcinoma and lung cancer show that IM-BPS is mostly better than EPID. Though validating for patients can be measured accurately and be well quality controlled, IM-BPS is used easily because of macroscopic, homely,spare time and real-time monitoring.

ABSTRACT

Objective To observe the incidence of RP in NSCLC and esophageal carcinoma treated with 3DCRT and investigate the relationship between acute RP and lung function and dosimetric parameters.Methods From October 2006 to August 2008, 3DCRT plus concurrent chemotherapy of NP or LFP were applied to 64 patients with locally advanced NSCLC or esophageal carcinoma. twenty-three patients suffered form NSCLC and 41 patients from esophageal carcinoma, the prescription doses were 60 Gy/30fx and 58 -64 Gy/29 -32fx, respectively. Results For patients with esophageal carcinoma, 34% developed RP(9 grade 1,3 grade 2 and 2 grade 3). For patients with NSCLC, 96% developed RP(9 grade 1, 8 grade 2 and 5 grade 3). There was significant difference between the two groups(t =5. 55,P=0. 000). The FEV1.0/FVC and DLCO of patients with NSCLC were significantly lower than those of esophageal carcinoma, the ratio were 75.6%:82.7%(t=2.75,P=0.008)and 71.7%:81.0%(t=2.50, P=0.015),respectively. For patients whose FEV1.0, FEV1.0/FVC%, DLCO <80% and ≥80% before irradiation,the incidence of ≥2grade ARP were 35% vs 25% ,31% vs 26% and 35% vs 19%, respectively(x2 = 1.81,0.15,2. 13,P =0.179,0.697,0.144). While for patients whose FEV1.0 < 70% and ≥70%, the incidence of severe ARP were 67% and 22% ,respectively(x2 =5.64, P =0.018). Spearman correlated analysis indicated that all the dosimetric parameters had relation with ≥ 2 grade ARP . The V20 of lung and MLD were found independently associated with RP according to multivariate analysis(x2 = 4.61,6.97, P = 0.032,0.008).Conclusions Parameters of basic lung function can predict the incidence of ≥2 grade RP to some extent,especially when the value of FEV1.0, FEV1.0/FVC%, and DLCO was lower. However, the V20 of lung and MLD may be the most valuable predictors.

ABSTRACT

Objective To observe the incidence of radiation pneumonitis (RP) in patients with non-small cell lung cancer (NSCLC) or esophageal carcinoma treated by three-dimensional conformal radiation therapy (3DCRT), and investigate the predictive value of low dose volume of the lung on RP.Methods From Mar 2005 to Aug 2008, 161 patients with locally advanced NSCLC or esophageal carcinoma received 3DCRT. Fifty-three patients with NSCLC received radiotherapy of 60 Gy/30 -34 fx and concurrent chemotherapy of navelbine plus cisplatin (NP). Among the 108 patients with esophageal carcinoma with prescription doses ranging from 58 Gy/29 fx to 70 Gy/35 fx, 46 and 62 received 3DCRT alone or 3DCRT with concurrent chemotherapy of calcium folinate, 5-Fu and cisplatin (LFP), respectively. Univariate and multivariate analysis and receiver operating characteristics (ROC) curves were performed to assess the correlated factors of RP. Results The follow-up rate was 100%. The rate of RP was 57. 8% (93/161) for all patients, 94% (50/53,including 1 with Grade 4 and 1 with Grade 5) for patients with NSCLC, and 39.8% (43/108, none with Grade 4 and 5) for patients with esophageal carcinoma. The correlative factors included the sex, volume of gross tumor volume (GTV), mean lung dose (MLD), V5, V10, V15, V20, V25 and V30 of normal lung according to Spearman correlative analysis. Univariate analysis showed that all the 9 factors could predict RP. Only V5 and the volume of GTV were found independently associated with Grade 2 or more RP in multivariate analysis. ROC analysis indicated that the cut-off point of the curve was 55% with the area under ROC curve of 0. 684 (P = 0. 000). For the patients with lung V5 ≥ 55% and < 55% ,43% (36/84) and 18% (14/77) developed RP of Grade 2 or more, respectively. Conclusions Dosimetric parameters including MLD, normal tissue complication probability, and V5-V30 could predict RP. V5 may be the most valuable predictor. When V5 exceeds 55%, the probability of RP of grade 2 or more may increase notably. Besides the limitation of MLD, V20 and V30, the volume of low dose region should be also limited to a lower range during treatment planning.

ABSTRACT

Primary malignant melanoma of the esophagus is extremely rare, with less than 200 cases reported in the literature. However, primary malignant melanoma is an aggressive tumor. We report a case of primary esophageal malignant melanoma that presented with a large polypoid mass in the lower esophagus, and subsequently showed multiple metastatic nodules in the subcutaneous layer, skin and retroperitoneum. Primary malignant melanoma should be included in the differential diagnosis of a polypoid esophageal mass, especially in cases where metastases to unexpected areas occur or in cases of unexpected metastatic patterns.

ABSTRACT

Diffuse esophageal leiomyomatosis is an exceedingly rare, benign, neoplastic condition occurring predominantly in children and young adults. This condition may occur as an isolated finding, or it may be associated with Alport syndrome. We report a case of diffuse esophageal leiomyomatosis with Alport syndrome in a 5-year-old girl who had presented with recurrent pneumonia, and present a review of the literature. We suspected Alport syndrome in the patient because she had a clinical history of congenital cataracts and hematuria, as well as imaging findings of diffuse esophageal leiomyomatosis. Alport syndrome was subsequently confirmed by electron microscopy of the kidney.

ABSTRACT

Benign esophageal lesions occur in various diseases. Barium studies are useful for the evaluation of mucosal surface lesions but provide little information about the extramucosal extent of disease. Computed tomography and magnetic resonance imaging, on the other hand, permit the assessment of wall thickness, mediastinal involvement, adjacent lymphadenopathy, and distant spread. In diseases such as fibrovascular polyps, duplication cysts, scleroderma, trauma, caustic esophagitis, hiatal hernia, esophageal diverticulum, achalasia, and paraesophageal varices, the findings of imaging studies are specific, obviating the need for further invasive diagnostic work-up. The advent of helical computed tomography and its volume data set allows the acquisition of multiplanar images, and magnetic resonance imaging is useful both for this and for tissue characterization. Thus, multiplanar cross-sectional imaging further extends the role of imaging modalities to the evaluation of benign esophageal lesions. Through an awareness of the multiplanar cross-sectional appearances of various benign esophageal lesions, the radiologist can play an important role in the detection, diagnosis, further diagnostic planning, and treatment of the diseases in which they occur.

ABSTRACT

Spindle-cell carcinoma of the esophagus is a rare malignant tumor composed of both carcinomatous and sarcomatous elements, and has generated many terminology problems. It is characterized by a bulky polypoid intraluminal mass with a lobulated surface located in the middle third of the esophagus. Local expansion of this organ is observed. The lesion may be pedunculated but despite its bulk, causes little obstruction. We report the imaging findings of a case of spindle-cell carcinoma arising in the upper esophagus.
