The incidence of transitional cell carcinoma of the kidney and ureter is low and for that reason limited data exists regarding the appropriate management of regional retroperitoneal lymph nodes. Lymph node metastases have consistently been associated with an adverse prognosis. However, five-year cancer-specific survival following nephroureterectomy and lymphadenectomy for patients with lymph node involvement ranges from 0–39%, suggesting a therapeutic benefit. This review covers the primary tumor characteristics associated with lymph node involvement, imaging of the lymph nodes, as well as the rationale, role, patient selection, suggested anatomic templates, and technical considerations for lymphadenectomy.

Aims and background Angiomyolipomas (AMLs) are benign hamartoid tumors which frequently occur in tuberous sclerosis (TS). They may be manifest at different organ sites such as kidneys, lymph nodes, liver and lung and may be associated with renal cell carcinoma (RCC). The nature of multiple organ involvement in AML (metastasis versus multicentric synchronous tumors), the malignant transformation and the relation of AML to RCC have not been sufficiently clarified. Study design Three cases of renal AMLs in patients with tuberous sclerosis associated with lymphangioleiomyomatosis of the paraaortic lymph nodes and/or with RCC are reported. The concise clinical history of the patients as well as the findings of histology, immunohistochemistry and quantitative DNA analysis are presented. Results The multicentric form of AML and coincidence of renal AML and RCC were observed in 2 patients. AML and RCC were found within the same focus in one of the cases. RCCs were either aneuploid or “near diploid”, whereas one of the multicentric AMLs showed a discordant DNA ploidy pattern, namely aneuploidy in the kidney and diploidy in the lymph nodes. Conclusions The presented cases (all of them underwent periaortic lymphadenectomy) suggest that lymph node involvement in renal AML may be more frequent than expected (1-2% of all AMLs) on the basis of the few reported cases. The discordant DNA ploidy (renal versus lymph node lesions) observed in one of the cases with multicentric AML implies synchronous tumor growth at different sites rather than metastatic disease. The intimate coexistance of RCC and AML (RCC revealed by immunohistochemistry within a larger mass of renal AML) may indicate that malignant transformation of an AML should only be accepted, if such a coincidence is unequivocally excluded.

13575 Background: The aim of this paper is an assessment of results of adjuvant chemoradiotherapy in patients with rectal cancer with respect to prognostic factors, causes of treatment failures and treatment tolerance. Methods: 178 pts with Dukes’ stage B or C rectal cancer received postoperative chemoradiotherapy between 1993 and 2002. Median age was 62; 110 patients were males, 68 were females. Median follow-up time was 45 months. Main endpoints of the analysis were locoregional recurrence-free survival (LRRFS), distant relapse free survival (DRFS), disease free survival (DFS) and overall survival (OS). Kaplan-Meier method was used to calculate survival rates. Univariate and multivariate analyses of prognostic factors were performed using log rank and Cox’s proportional hazard method. Results: The 5-year LRRFS was 73%, DRFS was 80%, DFS was 61% and OS was 65%. Lymph node involvement and method of resection (AR favoured) were the only independent prognostic factors for LRRFS. Lymph node involvement, in particular when four or more are involved, was independent prognostic factors for DFS. For DRFS are histological grade, lymph node involvement and extracapsular extension of the lymph node metastases. For OS, the independent prognostic factors were infiltration of the pararectal fatty tissue, lymph node involvement in particular when four or more are involved, total number of chemotherapy cycles (at least six favoured). The 5-year LRRFS was 73%, DRFS was 80%, DFS was 61% and OS was 65%. Radiation therapy was well tolerated in 45% of patients. Most common early reactions were diarrhoea, nausea/vomiting and leucopoenia. Conclusions: Involvement of lymph nodes and method of resection were the only independent prognostic factors for LRRFS. Prognostic factors for OS were infiltration of the pararectal fatty tissue, lymph node metastases, four or more involved lymph nodes, total number of chemotherapy cycles.

20014 Background: RCC in childhood is rare. Children with RCC tend to have a similar overall prognosis when compared with adults, where prognosis worsens with increasing stage, although direct comparisons of adult and paediatric data isn’t easy. The aim of our study is to identify the prognostic significance of local lymph node involvement in children with Renal Cell Carcinoma (RCC). Methods: On the basis of a retrospective study, the recently founded Italian Association for Paediatric Hematology and Oncology-Rare Tumors Paediatric Age (AIEOP-TREP) identified 16 patients (9 females) with RCC and local lymph node involvement at 10 of these centers. The cases were observed among 59 paediatric RCC, corresponding to 27.1% of RCC presenting in Italy from January 1973 to May 2006. Results: Overall, 9 patients were alive and disease free at last follow-up: eight patients had regional lymph node dissection (RLND) from the diaphragm at the aortic bifurcation, and one had the para-aortic lymph nodes removal. Six patients died: one had RLND (died from progression of disease), three had the renal hilum lymph nodes removal, and two the para-aortic lymph nodes dissection. One patient was lost to follow-up after relapse: this patient had para-aortic lymph node removal at diagnosis. Estimated 25-year DFS and OS rates for all patients were 64.2% and 50.5%, respectively. Given the small number of patients, little can be said about the value, if any, of adjuvant immunotherapy in this group of RCC. Conclusions: Children with lymph node positive RCC had a relatively unfavourable long- term prognosis. In our experience the RLND improves the prognosis. Further investigation of the biologic differences is warranted. Because of the very low incidence of paediatric RCC, an international clinical trial will be required to establish optimal therapy for children with RCC.

224 Background: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are a diverse group of malignancies affecting over 65,000 patients in the United States. GEP-NETs are currently classified as lymph node positive (N1) or negative (N0). The prognostic utility of the extent of lymph node involvement remains unknown. In this study, we used a population-based registry to investigate the relationship between lymph node ratio (LNR) and survival in patients with GEP-NETs. Methods: We used the Surveillance, Epidemiology, and End Results (SEER) data registry to identify patients with histologically confirmed, surgically resected NETs with lymph node involvement diagnosed between 1988 and 2011. Patients were divided into three groups based on the ratio of positive lymph nodes to total lymph nodes examined (LNR): ²0.20, >0.2-0.5, and >0.5. Kaplan-Meier, log-rank analysis, and Cox models were used to compare NET cancer-specific survival according to LNR category. Results: We identified 8,113 patients with GEP-NETs. Primary sites included small intestine (N=3,651), colon (N= 2,042), pancreas (N=1,070), appendix (N= 683), stomach (N=389), and rectum (N=278). Patients were 49% female, 76% white, and 12% black. Ten-year NET-specific survival rates were significantly different among patients in the three LNR groups and LN negative controls (p<.0001). Survival was worse in patients with LNRs of >0.2-0.5 (Hazard Ratio (HR) 1.338, p=.0002), and >0.5 (HR 1.692, p<.0001) compared to LN-negative controls. Higher LNR was correlated with worse survival. Conclusions: The degree of lymph node involvement is a prognostic factor across the most common primary sites of GEP-NETs. This information may be used clinically and in stratifying patients for clinical trials. Results across multiple sites may also be generalizable to GEP-NETs from rare primary locations that are difficult to study. [Table: see text]
