We present a case and review of the literature of well-differentiated sigmoid adenocarcinoma with numerous metastases into pericolic lymph nodes. All positive lymph nodes were small. The authors concluded that there is no clear correlation between nodal size and the likelihood of metastasis in the lymph node, and the status of small lymph nodes must receive special attention by clinicians and pathologists.

Lymph Node Retrieval

Abstract According to the American Joint Committee on Cancer, at least 12 lymph nodes are required to accurately stage locally advanced rectal cancer (LARC). Neoadjuvant chemoradiation therapy (NACRT) reduces the number of lymph nodes retrieved during surgery. In this study, we evaluated the effect of NACRT on lymph node retrieval and prognosis in patients with LARC. We performed an observational study of 142 patients with LARC. Although our analysis was retrospective, data were collected prospectively. Half the patients were treated with NACRT and total mesorectal excision (TME) and the other half underwent TME only. The number of lymph nodes retrieved and the number of metastatic lymph nodes were significantly reduced in the NACRT group (P > 0.001). In the univariate and multivariate analyses, only NACRT and patient age were significantly associated with reduced lymph node retrieval. The number of metastatic lymph nodes and the lymph node ratio (LNR) both had a significant effect on prognosis when the patient population was examined as a whole (P = 0.003 and P = 0.001, respectively). However, the LNR was the only significant, independent prognostic factor in both treatment groups (P = 0.007 for the NACRT group; P = 0.04 for the no-NACRT group). NACRT improves patient prognosis only when the number of metastatic lymph nodes is reduced. The number of metastatic lymph nodes and the LNR are important prognostic factors. Lymph node retrieval remains an indispensable tool for staging and prognostic assessment of patients with rectal carcinoma treated with NACRT.

76 Background: Some papers have reported that sentinel lymph node (SLN) concept can be applied in patients with early gastric cancer, in particular clinically T1N0M0 or T2N0M0 with a tumor diameter of 4cm or less. Little is, however, available on the SLN study with the other criteria than listed above. The aim of the present work was to investigate the accuracy of the SLN biopsy of gastric cancer with various stages and evaluate the indication for SLN navigated gastrectomy. Methods: A total of 431 consecutive patients were diagnosed with operable gastric cancer during the period April 1999 through December 2007. Reasons for inclusion were, in principle, T1N0M0 or T2N0M0 gastric cancer. However, several patients diagnosed preoperatively with T3N0M0, T2N1M0, remnant gastric cancer, multiple gastric cancers and additional treatment after endoscopic therapy were also enrolled in this study according to their request. All patients underwent a radical gastrectomy with SLN mapping with an informed consent. The SLNs were identified using both radio-guided and dye-guided method. Results: Detection rate of hot and/or blue node was 95.8% (413/431). The accuracy of metastatic status based on SLN was 97.6% (403/413). In six of 10 false-negative cases, some clinical backgrounds and problems were present; scirrhous gastric cancer, the tumor penetration of serosa, multiple lesions, remnant gastric cancer after partial resection and the technical issue of tracer injection. Nine of these 10 false-negative cases had the metastatic lymph nodes within only the sentinel basins. Specifically, in the group of clinically T1N0M0 untreated gastric cancer with a tumor diameter of 4 cm or less, there were only 3 false- negative cases. In addition, all the metastatic lymph nodes of the 3 cases located within the sentinel basins. Conclusions: Our study suggested that SLN concept for untreated early gastric cancer could be validated. The sentinel basin dissection might be used to advantage to improve curativity for gastric cancer. No significant financial relationships to disclose.
