Abstract Objective To investigate clinicopathological characteristics of double primary cancers of gastric cancer and breast cancer, so as to provide reference for following study of secondary primary tumor and (or) multiple primary cancers(MPC). Methods The clinicopathological data of 25 cases of double primary cancers of gastric cancer and breast cancer admitted from January 2001 to June 2013 in Beijing Cancer Hospital were analyzed. Among 25 cases, 6 cases had ovary carcinoma and (or) other malignant tumors. Results The middle onset age of the 1st primary cancer, mainly breast cancer, was 45 (30-66) years old, while that of the 2nd primary cancer was 54 (35-74) years old, mainly gastric cancer. The main pathology of gastric cancer was diffuse type accounting for 80%, while that of breast cancer was invasive ductal cancer accounting for 88%. The middle interval between the two cancers was 49 ??6.5-243.0??months. Conclusion Double primary cancers of gastric cancer and breast cancer have the characteristics of young onset age, short interval between two primary cancers and comorbidity with other primary cancers and family history, which indicates genetic susceptibility may play a role. For the treatment, early detection and early radical surgery can only prolong the survival.     

Peritoneal Dissemination of Early Gastric Cancer: Report of a Case

Recurrence of early gastric cancer is rare, with an incidence of less than 10% in Japan. Using peritoneal lavage cytological examination, we detected tumor cells in the peritoneal cavity of a 73-year-old man undergoing surgery for early gastric cancer. Peritoneal dissemination of early gastric cancer is rare. Thus, we summarized the clinicopathological findings of the total 15 cases of peritoneal dissemination of early gastric cancer documented in the English medical literature, including this case. All of the patients had a tumor size >2 cm, submucosal invasion, differentiated adenocarcinoma, lymph node metastasis, and a shorter disease-free interval (average 33.1 months) than patients with other types of recurrent early gastric cancer, and the involvement of both recurrent lymph nodes and peritoneal dissemination. Based on this analysis, we conclude that patients with early gastric cancer, especially if the tumor is >2 cm with submucosal invasion, should be examined carefully for any form of recurrence.     

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.     

Lymph node metastasis in early gastric cancer: how can surgeons perform limited surgery?

BACKGROUND: In Japan, the standard treatment policy for all potentially curable patients with gastric cancer is radical resection, including extensive lymph node dissection. The extent of lymph node dissection remains a controversial issue in the management of early gastric cancer. A recent trend in the surgical treatment of early gastric carcinoma has been to limit surgery such that a complete cure is achieved and the patient's quality of life is improved. However, approximately 10% of early gastric cancers are reported to be node positive and little is known about the protocol of surgical treatment most appropriate for the treatment of early gastric cancer. In this study, we examined the clinicopathological features that could distinguish node-positive cancer from node-negative cancer. PATIENTS AND METHODS: The clinicopathological features of 26 patients with node-positive early gastric cancer were reviewed from the database of gastric cancer at the Department of Surgery, Sendai National Hospital. They were compared with those of 239 patients with node-negative cancer. RESULTS: Tumor size, macroscopic appearance, depth of cancer invasion, histological growth pattern and lymphatic invasion were associated with lymph node metastasis. Node-positive patients with early gastric cancer had a poorer survival rate than node-negative patients (P<0.05). CONCLUSION: Limited surgery, such as local resection without lymphadenectomy, can be performed for elevated or flat type cancer, or tumor <2 cm in diameter. Lymphadenectomy is recommended to achieve higher possible cure rates for other early gastric cancers.     

早期胃癌内镜黏膜下剥离术后追加手术的原因分析

目的探讨早期胃癌内镜黏膜下剥离(endoscopic submucosal dissection,ESD)术后追加外科手术的原因。方法回顾性分析2015年1月~2019年8月ESD术后追加手术的23例早期胃癌共25处病灶的临床病理资料,包括内镜下表现、ESD病理结果及手术病理结果。结果早期胃癌ESD术后追加手术的原因有病灶侵犯黏膜下层19处(76%),分化类型差16处(64%),脉管内瘤栓8处(32%),阳性切缘9处(36%)。追加外科手术后病理提示肿瘤残留2例,淋巴结转移1例。随访2~53个月,中位数17个月,无复发及死亡。结论侵犯黏膜下层、分化类型差、脉管内侵犯以及基底切缘阳性是早期胃癌ESD术后追加手术的主要原因。     

极微小胃癌临床病理特征及治疗的探讨

目的 探讨极微小胃癌的临床病理学特点.方法 对2004年1月至2008年6月浙江大学医学院附属第二医院收治的296例早期胃癌患者中肿瘤直径≤10 mm的34例早期胃癌的临床病理资料进行回顾性分析,将其中5例直径≤2 mm的早期胃癌(极微小胃癌组)与29例直径在2～10 mm的早期胃癌(对照组)进行分组比较研究. 结果极微小胃癌占同期早期胃癌病例的2%;黏膜内癌在极微小胃癌组和对照组中分别占100%和45%;高、中分化型腺癌在极微小胃癌组和对照组分别占100%和55%;极微小胃癌组淋巴结转移率为0,对照组为3%;极微小胃癌组和对照组均未见脉管浸润;极微小胃癌组和对照组肿瘤表层部与浸润部病理组织学一致率分别为100%(5/5)和86%.结论 极微小胃癌常局限于黏膜内,组织学类型比较单一,以高、中分化腺癌为主,不伴淋巴结转移及脉管浸润,浸润部与表层部组织学分化程度较一致.极微小胃癌是内镜治疗的良好适应证.     

Gastrectomy with D2 lymph node dissection in gastric cancer: a retrospective study at a single institution

The purpose of this study was to clarify the clinicopathological characteristics of gastric cancer with lymph node (LN) dissection and the significance of D2 dissection by investigating surgical techniques and prognosis. Three hundred ninety patients with early cancer and 310 with advanced cancer underwent gastrectomy with D1 or D2 dissection, based on the presence or absence of LN metastasis determined pre- and intraoperatively. LN metastasis occurred in 10.5% of early gastric cancer patients, and several cases of advanced cancer were found to have N2 or more advanced metastasis. The pre- and intraoperative macroscopic findings accorded with histological grade of LN metastasis in 69.5% of early cancers and in 56.5% of advanced cancer patients. The false negativity rate was 6.8% in early cancer, 19.4% in advanced cancer, and 8.4% as a whole. Death was operation-related in only two cases and the operative mortality rate was low (0.29%). The 5-year survival rates in early and advanced gastric cancer were 95.8% and 67.6% in the D1 groups, respectively, and 100% and 89.5% in the D2 groups, respectively. Survival was better in the D2 groups than in the D1 groups (P < 0.0001 for early cancer, P = 0.0279 for advanced cancer). D2 dissection should be conducted positively for patients with LN metastasis.
