9569 Background: Mucosal melanoma is rare and associated with extremely poor prognosis. Little is known about its outcome and prognostic analysis. In this study, we evaluated prognostic factors among mucosal melanomas. Methods: The survival rates, Relapse Free Survival (RFS), Overall Survival (OS) and prognostic factors were compared for 706 mucosal melanomas at different anatomical sites. Results: Mucosal melanoma from nasal pharyngeal and oral (268 pts), upper and lower gastrointestinal (GI) (221 pts), gynecological and urological (196 pts) had a similar survival with a 1-y survival rate (88%, 83%, 86%), 2-y survival rate (66%, 57%, 61%), 5-y survival rate (27%, 16%, 20%), respectively. Multivariate analysis revealed that Depth of Invasion (p < 0.001), Lymph node metastases (p < 0.001), Distant metastases (p < 0.001) were three independent prognostic factors for OS among 706 pts. Anatomical site (p = 0.031), Depth of Invasion (p < 0.001), Lymph node metastases (p < 0.001) were three independent prognostic factors for RFS among 543 pts. KPS status, Depth of Invasion, Lymph node metastases, Distant metastases were independent factors for OS among nasal pharyngeal and oral pts. Depth of Invasion, Lymph node metastases, CKIT Mutation were independent factors for RFS among nasal pharyngeal and oral pts. Gender, Lymph node metastases, Distant metastases were independent factors for OS among GI pts. Gender, Depth of Invasion, Lymph node metastases were independent factors for RFS among GI pts. Lymph node metastases, Distant metastases were independent factors for OS among Gynecological and Urological pts. Depth of Invasion, Lymph node metastases were independent factors for RFS among Gynecological and Urological pts. Conclusions: This is the first prognostic analysis for mucosal melanoma with the largest sample size for the first time. with few exceptions, It revealed that Depth of Invasion, Lymph node metastases, Distant metastases were independent prognostic factors for OS, Depth of Invasion and Lymph node metastases were independent prognostic factors for RFS. These results should be incorporated into the establishment of stage system and design of future clinical trials involving patients with mucosal melanoma.

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.

Summary Aim: Evaluate the clinical benefit of external beam radiotherapy (RTx) for locally invasive thyroid carcinoma with follicular cell differentiation (DTC). Patients, methods: The Multicentre Study on Differentiated Thyroid Cancer (MSDS) was planned as a prospective multicenter trial on the benefit of adjuvant RTx in locally invasive DTC (pT4; UICC 1997) with or without lymph node metastases and no known distant metastases. All patients were treated with thyroidectomy, 131I-therapy, and TSH-suppression and were randomized to receive additional RTx or not. In 4/2003 the trial became a prospective cohort study after only 45 of then 311 patients had consented to randomization. 351 of 422 patients met the trial's inclusion criteria. Age was 48 ± 12 years (mean ± SD). 25% were men. Tumours were papillary in 90% and follicular in 10%. Of 47 patients randomized or allocated to RTx, 26 actually received RTx. Results: Mean followup was 930 days. In an actual treatment analysis, 96% (25/26) of the RTx-patients reached complete remission (CR) vs. 86% in the non-RTx patients. Recurrences occurred in 0 vs. 3 % of patients: 6 reoperated for regional lymph node metastases, 1 tracheal invasion treated with tracheoplasty, 1 local invasion necessitating laryngectomy, 2 distant metastases (1 lung, 1 lung + bone). Serious chronic RTx toxicity occurred in 1/26 patients. Conclusion: The MSDS trial showed low mortality and recurrence rates and a weak benefit of RTx in terms of local control that did however not reach statistical significance. Routine RTx in locally invasive DTC can no longer be recommended .
