Selected AbstractsPhase II trial of taxol in salivary gland malignancies (E1394): A trial of the Eastern Cooperative Oncology GroupHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 3 2006Jill Gilbert MD Abstract Background. Malignant tumors of the salivary glands make up approximately 5% of head and neck cancers. The Eastern Cooperative Oncology Group (ECOG) initiated a phase II evaluation of paclitaxel in patients with locally recurrent or metastatic salivary gland malignancies. Methods. Chemo-naive patients with histologically confirmed recurrent or metastatic carcinoma of salivary gland origin (mucoepidermoid, adenocarcinoma, or adenoid cystic) were eligible. Patients were treated with paclitaxel, 200 mg/m2 IV, every 21 days for a minimum of four cycles. Results. Forty-five patients were treated. Eight partial responses were seen among the 31 patients with mucoepidermoid or adenocarcinoma histologic findings for a response rate of 26%. No responses were seen in the adenoid cystic carcinoma group. No significant difference in overall survival was found among these three histologic subgroups. Conclusion. Paclitaxel demonstrates moderate activity in salivary gland tumors of mucoepidermoid and adenocarcinoma histology. The poor response rate in adenoid cystic carcinoma is consistent with prior reports in this chemoresistant histologic subtype. © 2006 Wiley Periodicals, Inc.

This study aims at exploring the relationship between MS and colorectal carcinoma. Methods:, Data was collected from 507 cases of colorectal carcinoma and 507 cases of healthy patients between January 2002 and March 2007 to establish the database. The patients with colorectal cancer were divided into two groups based on the presence of MS. Multivariate analysis of these data for the overall survival and recurrence was performed with the Cox proportional hazard model. Variables examined by multivariate analysis were sex , age, location, histotype, differentiation, tumour, node, metastasis (TNM) stage, the number of lymph nodes detected, etc. Results:, The existence of MS in the colorectal carcinoma group was clearly more than that in the control group. The existence of two to four types of abnormal metabolic diseases was significantly more in the colorectal cancer group than in the control group. MS is one of the important elements that can independently influence the survival (odds ratio (OR) = 1.501, 95% confidence interval (CI) = 1.057,2.131) and have the highest risk with worse survival compared with other parameters. Conclusion:, There is a close relationship between MS and colorectal carcinoma, and MS is a significantly independent element that influences the survival of the colorectal carcinoma. Decreasing the incidence of MS maybe play a role in improving therapeutic efficacy and prognosis of the cancer. [source] Long-term outcome of patients with insular carcinoma of the thyroidCANCER, Issue 10 2002The insular histotype is an independent predictor of poor prognosis Abstract BACKGROUND Insular thyroid carcinoma was described originally as a tumor with aggressive behavior. However, whether a predominant insular component is an independent factor for poor prognosis is unclear. METHODS The authors compared the clinical behavior of tumors in three groups of patients with thyroid carcinoma,13 patients with insular thyroid carcinoma, 18 patients with follicular thyroid carcinoma, and 26 patients with papillary thyroid carcinoma,who were selected based on similar tumor size and similar age. Disease free survival and disease specific deaths were assessed in the three groups with a Kaplan,Meier analysis and were compared using the log-rank test. Cox regression analysis was used to evaluate the influence of histotype and other prognostic factors on the occurrence of distant metastases and disease specific death. RESULTS Patient follow-up ranged from 5.2 months to 190.0 months. At last follow-up, only 1 of 13 patients (7.7%) with insular carcinoma, compared with 8 of 18 patients (44.4%) with follicular carcinoma and 12 of 26 patients (46.1%) with papillary carcinoma, were disease free. The disease specific death rate was 61.5% among patients in the insular carcinoma group compared with 16.7% and 15.4% among patients in the follicular carcinoma group (P = 0.006) and the papillary carcinoma group (P = 0.025), respectively. At multivariate analysis, the insular histotype was the only variable that was related independently to disease specific death (hazard ratio = 4.27; P = 0.005). Distant metastases occurred in 84.6% of patients in the insular carcinoma group compared with 50% and 19.2% of patients in the follicular carcinoma group (P = 0.039) and the papillary carcinoma group (P = 0.0003), respectively. All metastases from patients with insular carcinomas (n = 11 patients) showed radioiodine uptake, but a clinical benefit from this treatment was observed only in 1 patient. CONCLUSIONS Patients with insular thyroid carcinoma have a poorer outcome compared with patients of similar age who have differentiated types of thyroid carcinoma with tumors of a similar size. Because radioiodine rarely is effective in the treatment of patients with metastatic insular thyroid carcinoma, novel and possible multimodal therapies should be explored for the treatment of patients with these aggressive tumors.

To elucidate the role of the APC-/,-catenin pathway in UC-related carcinogenesis, the authors identified APC and ,-catenin mutations in a set of UC-related and sporadic colorectal carcinomas. METHODS The mutational cluster region of APC (codon 1267 to 1529) and exon 3 of the ,-catenin were directly sequenced. RESULTS Only 1 of 30 UC-related tumors (3%) showed an APC mutation whereas 11 of the 42 sporadic carcinomas (26%) had mutations within the mutational cluster region. Within the sporadic carcinoma group, only 8% of the right-sided carcinomas showed APC mutations whereas 50% of the left-sided carcinomas had mutations within the mutational cluster region. None of the tumors in either group showed a ,-catenin mutation. CONCLUSIONS Mutations of the APC and ,-catenin are rare in UC-related tumors. These genes may be altered because of mutations outside the regions studied, or by epigenetic silencing. Alternatively, other proteins involved in the APC/,-catenin signaling cascade may be altered, or this pathway may be involved infrequently in UC-related carcinogenesis. The significant difference in frequency of APC mutations between right- and left-sided sporadic tumors suggests different molecular pathways in these two tumor sites.
