Background
Mucosal (T1a) and submucosal (T1b) squamous cell carcinoma of the esophagus (ESCC) have often been analyzed together and are staged as the same category in the UICC/TNM staging system. The difference in surgical outcomes between T1a and T1b ESCC therefore remains unclear. The purpose of this study was to examine the differences in surgical outcomes between T1a and T1b ESCC, and to investigate the prognostic factors in T1 ESCC.Methods
A prospectively maintained database identified 145 previously untreated patients with pT1 ESCC who underwent radical transthoracic (n = 134) or transhiatal esophagectomy (n = 11). Median follow-up was 108 months.Results
Of the 145 patients, 35 (24 %) had pT1a cancer and 110 (76 %) had pT1b cancer. Lymph node metastasis was present in 45 patients (31 %): 3 patients with pT1a cancer and 42 patients with pT1b cancer (P = 0.0003). The 5-year survival rate for the whole group was 77 %. The 5-year survival rate of the T1a patients was 94 % compared with 72 % for the T1b patients (P = 0.0282). In multivariate analysis, only the depth of tumor invasion (pT1a vs. pT1b) was an independent prognostic factor (hazard ratio 2.358; 95 % confidence interval 1.009–5.513; P = 0.0477).Conclusions
After esophagectomy, the prognosis of patients with pT1b ESCC is significantly worse than that of patients with pT1a ESCC. Infiltration into the submucosa is the only independent prognostic factor affecting survival. These findings suggested that T1a and T1b ESCC could be staged separately in the next version of UICC/TNM staging system. 相似文献3.

Background Three-field lymph node dissection for thoracic esophageal cancer is associated with high morbidity and reduced quality of
life after surgery. Consequently, minimized lymphadenectomy would be desirable, if appropriate. In the present study, we retrospectively
analyzed the status of involved nodes and the direction of metastatic lymphatic flow from tumors into involved nodes to determine
whether submucosal squamous cell esophageal cancers are potential candidates for minimized lymphadenectomy.
Methods We enrolled 199 patients who received esophagectomy with extensive lymph node dissection between 1989 and 2005 and retrospectively
analyzed their prognoses, distribution of solitary metastatic lymph nodes, and the direction of metastatic lymphatic flow
from the tumor, taking into consideration tumor location and depth.
Results Of these patients with submucosal cancers, 83% had 1 or 2 involved nodes, and their esophageal cancer-specific 5-year survival
rate was 66%. Solitary lymph node metastasis did not occur in neck lymph nodes in lower thoracic submucosal esophageal cancers,
and the direction of metastatic lymphatic flow from the tumor was almost always in one direction. By contrast, T2–4 cancers
with 2–4 involved nodes had bidirectional metastatic lymphatic flow from the tumor.
Conclusions There was a difference in the status of lymph node metastasis and the direction of metastatic lymphatic flow from tumors into
involved nodes between submucosal and T2–4 thoracic squamous cell esophageal cancers. This analysis may be useful for developing
an approach to minimized lymphadenectomy for thoracic esophageal cancers. 相似文献

Background
More than 40 % of patients with submucosal esophageal squamous cell carcinoma (ESCC) have lymph node metastasis. Furthermore, the potential presence of undetectable metastasis before treatment prompts surgeons to be aggressive with respect to lymph node dissection. Extending the indication for endoscopic resection, a minimally invasive treatment, to superficial ESCCs will require more accurate and individualized evaluation of lymph node metastasis.Methods
The study participants were 121 esophageal cancer patients who underwent curative surgery for thoracic submucosal ESCC at three Japanese hospitals. DNA was extracted from blood samples, and the C-reactive protein (CRP) 1846C>T genetic polymorphism (rs1205) was investigated using polymerase chain reaction-restriction fragment length polymorphism. We then evaluated the value of CRP 1846C>T polymorphism for diagnosis of lymph node metastasis.Results
Forty-nine (40 %) patients had lymph node metastasis. The CRP 1846 C/T genotype was C/C in 19 patients, C/T in 57 patients, and T/T in 45 patients. Fisher’s exact analysis of the CRP 1846C>T polymorphism showed a significantly higher frequency of lymph node involvement with the T/T genotype. Univariate and multivariate logistic regression models revealed that patients carrying the 1846 T/T genotype had a significantly greater likelihood of developing lymph node metastasis (odds ratio >2.6). Combining the CRP 1846 C/T genotype with clinical diagnosis, mainly using CT, brought a negative predictive value of 80 % to diagnosing lymph node involvement.Conclusions
CRP genetic polymorphism may be a novel predictor of risk of lymph node metastasis in ESCC, which could enable better evaluation of the necessity for lymph node dissection. 相似文献5.

BACKGROUND: The purpose of this study was to better understand the role of osteopontin (OPN) in esophageal squamous cell carcinoma (ESCC) by comparing the OPN mRNA level in ESCC tumor tissue and matched normal tissue and by determining the prognostic significance of the gene expression. METHODS: Initially, by an oligo-nucleotide microarray hybridization technique, OPN expressions were found to consistently elevate at least twofold in three ESCC tissues compared with their adjacent normal ones. Subsequently, the expression of OPN mRNA was detected by real-time QRT-PCR among the 58 fresh surgical ESCC specimens. The clinical information was obtained by chart review. RESULTS: OPN mRNA expression was detectable in 58 of 58 (100%) tumor specimens and 57 of 58 (98.3%) nonmalignant esophageal specimens. OPN expression was higher in tumor tissue than in the matched normal tissue in 54 of 58 (93.1%) individual cases. The overall median mRNA expression level of OPN was approximately 8.8-fold higher in tumor tissues (4.1; range: 0.02-247) compared with matched normal esophageal tissues (0.5; range, 0.0-21.4; p < 0.001). Overexpression of OPN mRNA was significantly associated with clinical stage (p = 0.01). The more severe the clinical stage (from I-II, III, to IV) was the higher frequency of overexpression of OPN mRNA. No significant associations were found between overexpression of OPN mRNA and the patients' survival (p = 0.27). DISCUSSION: Our findings suggest OPN is associated with esophageal tumorigenesis and progression, but not patients' survival. 相似文献

Background
Tumor budding is defined as an isolated single cancer cell or a cluster of cancer cells composed of fewer than five cells at the invasive front of a tumor. The aim of the present study was to identify correlations between tumor budding and clinicopathological factors and their impact on postoperative prognosis in invasive squamous cell carcinoma of the thoracic esophagus. 相似文献9.

Background Vascular endothelial growth factor C (VEGF-C) is the only factor known to cause lymphangiogenesis. In esophageal cancer the
histologic tumor type and lymph node metastasis are independent predictors of recurrence and poor outcome. To evaluate the
rule of VEGF-C expression in esophageal cancer, we investigated 113 specimens, 59 squamous cell and 54 adenocarcinomas of
the esophagus.
Methods The expression of VEGF-C was evaluated using immunohistochemistry (IHC) on 59 paraffin-embedded archival specimens from patients
with squamous cell esophageal carcinomas and 54 paraffin-embedded archival specimens of patients with esophageal adenocarcinomas
arising in Barrett’s mucosa. All patients had a complete tumor resection. A complete and updated follow-up was available for
all patients.
Results The expression of VEGF-C was significantly different between the two histological types of esophageal tumors. Patients with
squamous cell carcinoma and lymph node metastases had a significantly higher VEGF-C expression (P < 0.01). In patients with adenocarcinoma of the esophagus there was no correlation between VEGF-C expression and clinicopathological
parameters. High VEGF-C expression tended to be correlated with poor survival in squamous cell cancer but not in adenocarcinoma
of the esophagus.
Conclusions The present study indicates that VEGF-C may play a role in tumor progression via lymphangiogenesis in squamous cell carcinoma
of the esophagus. This seems not to be true for the adenocarcinoma of the esophagus. These data could help with the understanding
of the different onset and characteristics of lymph node metastasis in squamous cell carcinoma and adenocarcinoma of the esophagus. 相似文献

Akihiro Homma MD Ryuichi Hayashi MD Kazuto Matsuura MD Kengo Kato MD Kazuyoshi Kawabata MD Nobuya Monden MD Yasuhisa Hasegawa MD Tetsuro Onitsuka MD Yasushi Fujimoto MD Shigemichi Iwae MD Kenji Okami MD Takashi Matsuzuka MD Kunitoshi Yoshino MD Ken-ichi Nibu MD Takakuni Kato MD Hiroshi Nishino MD Takahiro Asakage MD Ichiro Ota MD Morimasa Kitamura MD Akira Kubota MD Tsutomu Ueda MD Kaichiro Ikebuchi MD Akihito Watanabe MD Masato Fujii MD 《Annals of surgical oncology》2014,21(5):1706-1710
Background
The purpose of this study was to evaluate the incidence of lymph node metastasis among patients with T4 maxillary sinus squamous cell carcinoma (MS-SCC) as well as the delayed metastasis rate and the treatment outcome for untreated N0 neck in patients with T4 MS-SCC.Methods
Consecutive series of all patients (n = 128) with previously untreated T4 maxillary sinus SCC between 2006 and 2007 were obtained from 28 institutions belonging to or cooperating in the Head and Neck Cancer Study Group of the Japan Clinical Oncology Group.Results
Of the 128 patients, 28 (21.9 %) had lymph node metastasis, and six patients (4.7 %) had distant metastasis at diagnosis. Among the 111 patients who were treated with curative intent, 98 had clinically N0 neck disease and did not receive prophylactic neck irradiation. A total of 11 patients (11.2 %) subsequently developed evidence of lymph node metastasis, of whom eight were among the 83 patients with an N0 neck and had not received elective neck treatment. There were 15 patients who received an elective neck dissection as part of the initial treatment, of whom three had pathologically positive for lymph node metastases. Of 11 patients, six patients with nonlateral retropharyngeal lymph node metastasis without primary or distant disease were successfully salvaged.Conclusions
This study identified the incidence of lymph node metastasis among patients with T4 MS-SCC as well as the delayed metastasis rate and the treatment outcome for untreated N0 neck in patients with T4 MS-SCC. These results will be of assistance in selecting treatment strategy for T4 MS-SCC in the future. 相似文献14.

Background
Two randomized trials have shown that in patients with good response to neoadjuvant chemoradiotherapy (nCRT), a nonoperative approach (additional CRT) had equal survival to scheduled esophagectomy. However, controversy exists because of the high locoregional recurrence (LR) following a nonoperative approach. Endoscopic complete response (e-CR) determined by endoscopic finding is a good criterion for predicting local control after definitive CRT. We evaluated whether e-CR could also be used to select patients for nonoperative treatment after nCRT.Methods
We retrospectively analyzed esophageal squamous cell carcinoma (SCC) patients with e-CR after nCRT between 1999 and 2006. Patients were divided into two groups by the type of treatment given after e-CR (group A, scheduled esophagectomy; group B, no scheduled surgery and continued CRT).Results
There were 71 and 79 patients in groups A and B, respectively with similar pre/post-nCRT characteristics. Despite similarity in survival and recurrence between groups, the recurrence site differed significantly. LR occurred more frequently in group B, whereas systemic recurrence was the predominant failure pattern in group A (P < .001). With use of multivariate analysis on group B, we determined that pretreatment depth of tumor invasion ≥T3 [odds ratio (OR), 11.19; 95 % CI, 1.4–89; unfavorable, P = .023] and tumor length ≥6 cm (OR, 3.069; 95 % CI, 1.17–8.1; unfavorable, P = .023) were predictors for LR. Patients with initial clinical T2 and <6 cm tumor had comparable LR (5 %) to the surgery group; these patients were candidates for nonoperative treatment after nCRT.Conclusion
In esophageal SCC patients who achieved e-CR after nCRT, pretreatment tumor depth and length were good indicators to select candidates for nonoperative treatment. 相似文献15.

Background
Epithelial-mesenchymal transition has recently attracted great attention in studying the malignant progression of cells through a converging pathway of oncogenesis and metastasis. Twist1 and Mastermind-like 1 (MAML1) are major regulators of EMT through different pathways. The aim of this study was to investigate the clinicopathological relevance of the expression of MAML-1 and Twist1 genes in esophageal squamous cell carcinoma (ESCC). 相似文献16.

The aim of this prospective study is to report our experience in the multimodal management of locally advanced esophageal squamous cell carcinoma (LAESC; stage III cTNM), focusing on the results of chemoradiotherapy followed by surgery. These findings were compared to the results of a standard group of patients with locally advanced esophageal carcinoma (LAEC; stage III pTNM) treated in our center with surgery alone. Sixty-one patients with LAESC underwent preoperative chemoradiotherapy (5-fluorouracil + cisplatin) with concomitant 45 Gray radiotherapy in a 5-week course. Transthoracic esophagectomy was performed 4 to 5 weeks after the end of the neoadjuvant therapy. Thirty-eight patients underwent surgery, and 37 of them had resections (resectability: 97% in the multimodal group; 84% in the standard surgical series; p = 0.07). The R0 (complete) resection rate was 78% compared to 56% in the standard surgical group (p <0.03). Eleven patients had no residual tumor in the resected specimen (pathologic complete response: pCR: 30%). The operative mortality rate was 19% compared with 8.8% in the standard series. The overall median survival of the resected patients was 21 months, with a 5-year survival rate of 11% (14% in the surgical group; NS). The 3-year and 5-year survival rates were 34% for the pCR group and respectively 5% and 0% for the group with pathologic incomplete response (pIR; p <0.05). The median survival was 28 months for the pCR patients and 19 months for the pIR group. In this non-randomized trial, preoperative chemoradiotherapy in LAESC seems to increase the resectability and R0 resection rates, to allow a higher pCR rate and a longer survival only in the pCR group, at the expense of an inadequate increase in operative mortality. This multimodal treatment cannot be proposed as a standard procedure unless less toxic regimens are developed, increasing the benefits with better local and distant failure control and decreasing operative mortality. 相似文献

There is increasing evidence regarding extracapsular lymph node involvement (LNI) as a prognostic factor for recurrence and
poor prognosis in gastrointestinal malignancies. The aim of this study was to assess the prevalence and prognostic impact
of LNI in patients with resected esophageal cancer, comparing adenocarcinoma (AC) and squamous cell carcinoma (SCC). Between
1997 and 2006, 243 consecutive patients with resected esophageal cancer without neoadjuvant therapy (103 SCC, 140 AC) were
studied. A total of 738 lymph node metastases were reexamined. Survival was analyzed according to intra- and extracapsular
LNI. Median survival in patients with extracapsular LNI was 13 months [range 11–14 months, 95% confidence interval (CI)] compared
with 28 months (21–34 months, 95% CI) for those with intracapsular LNI alone (p = 0.017). Node-positive patients with AC showed a prevalence of 66% extracapsular LNI compared with 35% in patients with
SCC (p < 0.001). The number of resected lymph nodes and the frequency of pN1 cases were comparable between AC and SCC. However the
number of infiltrated LN was significantly (p = 0.005) higher in patients with pN1 AC (median = 5) compared with pN1 SCC (median = 3). We conclude that extracapsular LNI
is an independent negative prognostic factor which occurs more frequently in esophageal AC than SCC. 相似文献

Background The presence of intratumoral lymphatic vessels (ILVs) and the expression of vascular endothelial growth factor-C (VEGF-C)
in tumour cells have been studied as markers of lymphangiogenesis in order to evaluate their role in metastatic dissemination
in laryngopharyngeal squamous cell carcinoma.
Methods A retrospective study was performed in 76 patients of N0 laryngopharyngeal carcinoma. with variable tumour size (T1-T4), histological
grade, and location (supraglottic, glottic and hypopharyngeal). The presence of ILVs, as revealed by the expression of PA2.26
antigen and VEGF-C expression, were determined by immunohistochemistry (IHC). Low-grade and high-grade lymphangiogenesis were
defined by qualitative and quantitative criteria.
Results Multivariate analysis revealed low-grade ILV and VEGF-C expression to be associated respectively with 30.3- and 16.2-fold
higher probabilities of cervical lymph node relapse (P = 0.005 and P = 0.032) and with 16.2- and 8.44-fold shorter disease-free survival (P = 0.009 and P = 0.045).
Conclusions Low-grade ILV and VEGF-C expression are independent predictive factors of cervical lymph node relapse and shortening of time
to relapse in N0 laryngopharyngeal carcinoma. 相似文献
