Aim Colorectal cancer (CRC) is one of the most prevalent malignancies in Argentina with 11,043 new cases and 6,596 deaths estimated to have occurred in 2008. The present study was developed to clarify the differential expression of MUC1, MUC2, sLex, and sLea in colorectal cancer patients and their relationship with survival and clinical and histological features. Methods Ninety primary tumor samples and 43 metastatic lymph nodes from CRC patients were studied; follow-up was documented. Twenty-six adenoma and 68 histological normal mucosa specimens were analyzed. An immunohistochemical approach was applied and statistical analysis was performed. Results In tumor samples, MUC1, sLea, and sLex were highly expressed (94%, 67%, and 91%, respectively); also, we found a significantly increased expression of the 3 antigens in primary tumors and metastatic lymph nodes compared with normal mucosa and adenomas. MUC2 was expressed in 52% of both normal mucosa and CRC samples; this reactivity significantly decreased in metastatic lymph nodes (p<0.05). A multiple comparison analysis showed that MUC1 and sLex discriminated among 3 groups: normal, adenoma, and CRC tissues. The increase of sLex expression showed an association with recurrence, and survival analysis showed that a high sLex staining was significantly associated with a poor survival. By multivariate analysis MUC1 inmunoreactivity correlated positively and significantly with tumor size, while MUC2 expression showed the opposite correlation. Conclusions The correlation of sLex overexpression in primary tumors and metastatic lymph nodes, the discrimination among the normal, adenoma, and CRC groups based on sLex expression, as well as its association with recurrence and survival, all suggest a prognostic role of sLex in Argentinian CRC patients.

e15113 Background: A recent study demonstrated that colorectal cancer with ovarian metastases were less responsive to chemotherapy compared to extraovarian metastases. Hence, the ovary may actually represent a “sanctuary” for metastatic cells from CRC. The aim of the study was to investigate the impact of oophorectomy on survival of colorectal cancer patients with ovarian metastasis. Methods: Between 1996 and 2008, 83 colorectal cancer patients underwent oophorectomy. For the historical control, 47 colorectal cancer patients without oophorectomy were included in the analysis. Survival and its associated factors were analyzed using Kaplan-Meier method, log-rank test and Cox-regression analysis. Results: The median age was younger (48 years) in the oophorectomy group when compared to the historical control (54 years) (P =.012). The proportion of synchronous metastasis was higher in the oophorectomy than the control group (57% vs 30%, respectively; P=.003). After a median follow-up duration of 60.8 months (range, 7.4 - 169.7 months), the median OS was significantly longer in the oophorectomy group (28.1 vs 21.2 months, oophorectomy vs non-oophoreectomy; P=.038). For ovary-specific survival (date of ovarian metastasis diagnosis to death), colorectal cancer patients with oophorectomy showed significantly favorable survival than the control group (20.8 vs 10.9 months, respectively; P<.001). At univariate analyses, no oophorectomy (P=.038), bilaterality of ovarian metastasis (P=0.032), the presence of extraovarian metastasis (P<0.001), elevated CEA (p<0.001), poor performance status (p=0.001), no palliative chemotherapy(p=0.001), no primary disease resection(p=0.005) were identified as significantly poor prognostic factors for overall survival. The no oophorectomy, no chemotherapy, extraovarian metastasis, elevated CEA, poor performance status retained statistical significance at multivariate level. (p=0.003, p=0.004, p=0.005, p=0.015, p=0.029, respectively). Conclusions: Based on this retrospective analysis, the oophorectomy significantly prolonged survival in colorectal cancer patients with ovarian metastases. A potential role of oophorectomy in the management of colorectal cancer should be prospectively studied. No significant financial relationships to disclose.
