Physical exam was unremarkable. Methods: Whole Abdominal CT Scan showed carcinomatosis and non-specific splenic hypodensities. Diagnostic laparoscopy, Omental biopsy and Peritoneal Fluid Cytology was done which showed Mucinous Adenocarcinoma (Omentum). Patient was then started on Capecitabine. Patient was subsequently readmitted 8 months after because of melena. Contrast-enhanced CT scan of the whole abdomen showed diffuse peritoneal nodularities and selleck chemical stranding and dilated appendix. Results: Patient then underwent exploratory laparotomy, debulking omentectomy, appendectomy and splenectomy. Biopsy revealed Appendiceal Mucinous adenocarcinoma with pseudomyxoma peritonei. 4 months after, patient

is undergoing systemic chemotherapy and follow-up Contrast-enhanced CT scan showed no peritoneal recurrence. Conclusion: Appendiceal Carcinoma is one of the rarest malignancies. Most of them are diagnosed incidentally on imaging studies. Because of its rarity, limited randomized controlled studies are available for its treatment.

CHU Affiliations: XAV-939 mw east avenue medical center Objective: The incidence of colorectal cancer in young adults has been increasing. These young adults

are usually not screened, unless they have family history or symptoms that would warrant colonoscopy. This study aims to document the clinical characteristics, histopathology, and proportion of colorectal cancer patients less than 50 years old from 2000 to 2012. Methods: This is a retrospective

review of records of colorectal cancer cases from the Tumor Clinic of East Avenue Medical Center from 2000 to 2012. Subjects less than 50 years old were compared to those 50 and above. Fossariinae Frequency counts, percentages and chi-square test were obtained with the use of 95% confidence interval. Results: Out of the 454 patients included in this study, 42% (191/454) of cases were less than 50 years of age. Family history of colorectal cancer was noted in 5.8% (11/191) of subjects less than 50 years of age and 4.9% (13/263) among those 50 and above. Poorly differentiated adenocarcinoma was seen in 25% (43/172) of the younger population while it represents only 14% (33/241) of the older group (p = 0.010). From 2007 to 2008, 38% of all colorectal cases were below 50 years old. This increased to 45% in 2009–2010 and to 55% in 2011–2012. Conclusion: This study showed that 42% of all colorectal cancer patients were below 50 years old. In the last 6 years, an increasing proportion of colorectal cancer patients below 50 years old were noted. These findings suggest earlier screening in this age group and further studies in different settings. Key Word(s): 1. COLON CANCER; 2. FILIPINO; 3.
