Risk Factors for Lymph Node Metastasis in Undifferentiated Early Gastric Cancer

Background Endoscopic surgery has not been accepted as a curative treatment for intramucosal undifferentiated early gastric cancer (EGC). The purpose of this study was to evaluate the predictive factors of lymph node metastasis and explore the possibility of using endoscopic surgery for undifferentiated EGC. Methods We retrospectively analyzed 646 patients with undifferentiated EGC who had undergone gastrectomy with D2 lymphadenectomy from January 2000 to March 2005. We used univariate and multivariate analysis to identify clinicopathological features that were predictive factors for lymph node metastasis. Results The incidence of lymph node metastasis was 4.2% in intramucosal and 15.9% in submucosal undifferentiated EGC. Multivariate analysis revealed that submucosal invasion, larger tumor size (greater than 2 cm), and presence of lymphovascular invasion (LVI), were significantly associated with lymph node metastasis in patients with undifferentiated EGC. Tumor size and LVI were independent risk factors for lymph node metastasis in cases of intramucosal EGC. Lymph node metastasis was found in only one patient (0.5%) who had neither of the two risk factors for intramucosal EGC. Conclusion Complete endoscopic resection may be acceptable as a curative treatment for intramucosal undifferentiated EGC when the tumor size is less than or equal to 2 cm, and when LVI is absent in the postoperative histological examination. Radical gastrectomy should be recommended if LVI or unexpected submucosal invasion is present.     

Endoscopic treatment or surgery for undifferentiated early gastric cancer?

BACKGROUND: Although almost all (96%) the surgical cases of undifferentiated intramucosal early gastric cancer (EGC) have been found not to have lymph node metastasis (LNM), local treatment by endoscopic mucosal resection (EMR) is not accepted as an alternative treatment to surgery for this type of EGC. If a subgroup of patients with undifferentiated EGC with negligible risk of LNM can be defined, unnecessary surgery can be avoided. This study was conducted to determine this subgroup among undifferentiated EGC patients in whom the risk of LNM can be highly ruled out in an attempt to identify candidates who can be treated by EMR. METHODS: Data from 175 patients surgically resected for undifferentiated EGC were retrospectively collected, and clinicopathological factors were multivariately analyzed to identify predictive factors for LNM. RESULTS: Multivariate logistic regression analysis identified two independent risk factors for LNM, namely, a large tumor (>/=20 mm, P = 0.011) and presence of lymphatic involvement (P = 0.0005). Using these two risk factors as the predictive factors, LNM was observed in 5.8% of patients who had neither of the two predictive factors, whereas 23.1% or 13.1% of patients with one or two predictive factors had LNM, respectively. In contrast, the LNM rate was calculated to be 60% in patients who had both factors. Lymph node metastasis was not found in any of 6 patients with small intramucosal lesions (<10 mm) without lymphatic involvement. CONCLUSIONS: An intramucosal undifferentiated EGC that is smaller than 10 mm without lymphatic involvement can safely be treated by EMR alone, given the negligible possibility of LNM. When histological examination of endoscopically resected specimens shows lymphatic involvement or unexpectedly larger tumor size than that determined at pre-EMR endoscopic diagnosis, an additional surgical procedure should be considered.

Predictive factors for lymph node metastasis in early gastric cancer with signet ring cell histology and their impact on the surgical strategy: analysis of single institutional experience

Background

The prognosis of early gastric cancer (EGC) with signet ring cell histology is more favorable than other undifferentiated gastric adenocarcinomas. An accurate assessment of potential lymph node metastasis is important for the appropriate treatment of EGC with signet ring cell histology. Therefore, this study analyzed the predictive factors associated with lymph node metastasis in patients with this type of EGC.

Methods

A total of 136 EGC with signet ring cell histology patients who underwent D2 radical gastrectomy were reviewed in this study. The clinicopathologic features were analyzed to identify predictive factors for lymph node metastasis.

Results

The overall rate of lymph node metastasis in EGC with signet ring cell histology was 10.3%. Using a univariate analysis, the risk factors for lymph node metastasis were identified as the tumor size, depth of tumor invasion, and lymphovascular invasion. The multivariate analysis revealed that tumor size >2 cm, submucosal invasion, and lymphovascular invasion were independent risk factors of lymph node metastasis (P < 0.05).

Conclusions

The risk of lymph node metastasis of EGC with signet ring cell histology was high in those with tumor sizes ≥2 cm, submucosal tumors, and lymphovascular invasion. A minimally invasive treatment, such as endoscopic resection, might be possible in highly selective cases of EGC with signet ring cell histology with intramucosal invasion, tumor size <2 cm, and no lymphovascular invasion.     

Significant prognostic factors in patients with early gastric cancer

BACKGROUND: Early gastric cancer is defined as a gastric carcinoma confined to the mucosa or submucosa regardless of lymph node status, and it has an excellent prognosis with a 5-year survival rate of more than 90%. From 1985 to 1995, we encountered 266 cases of early gastric cancer in our hospital. METHODS: A retrospective analysis of the 266 cases of early gastric cancer was performed to evaluate the prognostic significance of clinicopathological features (age, gender, tumor size, tumor location, depth of invasion, lymph node metastasis, histological type, lymphatic invasion, vascular invasion, histological growth pattern, cancer-stromal relationship and type of operation). RESULTS: The overall survival rate of all the patients with early gastric cancer was 95.7%. In univariate analysis, the statistical significant prognostic factors were regional lymph node metastasis (P = 0.0004), lymphatic invasion (P = 0.0053) and cancer-stromal relationship (P = 0.0016). Absence of lymph node metastasis and lymphatic invasion, and a medullary-type histopathology were associated with improved survival. In multivariate analysis, the statistically significant prognostic factors were lymph node metastasis and cancer-stromal relationship. CONCLUSIONS: Presence of lymph node involvement and a scirrhous type of gastric cancer are associated with poor prognosis. Lymph node dissection with gastric resection is necessary for patients with early gastric cancer who have a high risk of lymph node metastasis. Postoperative chemotherapy is recommended for a scirrhous type of early gastric cancer.     

早期胃癌患者临床病理因素与预后的关系

目的 探讨早期胃癌患者临床病理因素与预后之间的关系,为制定合理的治疗方案提供帮助.方法 回顾性分析2002年1月至2007年10月复旦大学附属中山医院收治的459例接受D2手术的早期胃癌患者的临床资料.Kaplan-Meier法计算生存率,Log-rank检验进行单因素分析,Cox回归模型分析年龄、性别、肿瘤直径、大体类型、分化程度、浸润深度、淋巴管浸润、淋巴结转移数目对预后的影响.结果 肿瘤直径、分化程度、浸润深度、淋巴管浸润和淋巴结转移数目影响早期胃癌患者预后(χ~2=8.476,6.210,4.014,14.197,55.027,P<0.05).是否有淋巴结转移是影响早期胃癌预后的独立危险因素,且淋巴结转移数目越多,对预后的影响越大.结论 淋巴结转移是影响早期胃癌预后最为重要的因素,适度地施行淋巴结清扫有重要的意义,对于存在淋巴结转移高危因素的患者更应谨慎地施行微创手术.     

Histopathologic Criteria for Local Excision of Colorectal Cancer: Multivariate Analysis

Background: Local treatment of colorectal cancer, including endoscopic removal of colonic polyps and transanal resection of rectal tumors, has become widely accepted. However, risk factors predicting the presence of lymph node metastasis have not been fully investigated. To determine the criteria for local excision of colorectal cancer, histopathologic factors independently predicting the lymph node metastasis were investigated.Methods: We performed a retrospective histopathologic study on 335 patients who underwent resection of colorectal cancer and dissection of regional lymph nodes between 1982 and 1996. Features of node-positive tumors (n = 150) were compared with those of node-negative tumors (n = 185), with special reference to the histopathologic findings of the resected tumor. Multivariate analysis was done using the stepwise logistic regression test.Results: Node-positive tumors, when compared with node-negative tumors, were characterized by tumor larger than 6 cm (42% vs. 22%), serosal invasion (88% vs. 56%), lymphatic invasion (32% vs. 5%), venous invasion (9% vs. 2%), and histology other than well-differentiated (66% vs. 29%). Multivariate analysis showed that factors independently associated with lymph node metastasis were serosal invasion, lymphatic invasion, and histologic type. When these three risk factors were negative, lymph node metastasis was rare (5%). When one, two, or three factors were positive, the frequency of lymph node metastasis was 38%, 66%, and 85%, respectively.Conclusions: In colorectal cancer, factors independently associated with lymph node metastasis are serosal invasion, lymphatic invasion, and histologic type. When these three parameters are favorable, local treatment of colorectal cancer does not require additional lymph node dissection.     

Probability of lymph node metastasis in small gastric cancer tumor: is it an indication for limited surgery?

The purpose of this study was to determine the factors that are predictive of lymph node metastasis in a small gastric cancer tumor <2 cm in diameter. The clinicopathological features of 17 patients with node-positive small gastric cancer were reviewed from the database of gastric cancer at the Department of Surgery, Sendai National Hospital, Sendai, Japan, and they were compared with those of 131 patients with node-negative cancer. The independent risk factors influencing the lymph node metastasis were determined by multiple logistic regression analysis. Depth of invasion, macroscopic appearance, cancer-stromal relationship, and lymphatic microinvasion were found to be associated with lymph node metastasis. The variables found to be significant risk factors for lymph node metastasis were depth of invasion (P = 0.0250) and lymphatic microinvasion (P = 0.0028). It is possible for even a small gastric cancer tumor to have lymph node metastasis. A surgeon treating a small gastric cancer tumor must consider that although the cure rate is high, >10% of these tumors have lymph node metastases. Because of the possibility of lymph node metastasis, even with accurate knowledge of the depth of cancer invasion, selective performance of local resection or limited surgery with incomplete lymph node dissection is not justified. Accurate preoperative diagnosis and the appropriate decision for surgical indication are important. Large-scale randomized, controlled trials should be performed to show the advantage of limited surgery for gastric cancer.
