Purpose: Although computed tomography (CT) is widely used for diagnosing liver metastasis from colorectal cancer, diagnostic accuracy of CT is not satisfactory. Magnetic resonance (MR) imaging and F-18 FDG PET has been reported to be superior to CT. However, studies on direct comparison of PET and MR are scarce. We compared the diagnostic accuracy of FDG PET and MR in detecting liver metastasis from colorectal cancer. Materials and Methods: Among 363 colorectal cancer patients who underwent F-18 FDG PET (ECAT, Siemens-CTI, Knoxville; Gemini, Philips, Milpitas, U.S.), 26 patients (M:F=17:9, age=$62{\pm}11$) underwent MR to evaluate suspicious metastatic liver lesions. Finally, 35 liver lesions detected by CT from 26 patients were enrolled for analysis. PET and MR results were compared with pathologic reports, clinical findings or follow-up results. Results: Of the 35 lesions, 18 lesions (51.4%) were diagnosed as liver metastases, while remaining 17 (48.6%) as benign. The sensitivity and the specificity of PET were 94.4% and 94.1%, respectively, compared to 100% and 82.4% for MR. MR and PET was concordant in 30 lesions (85.7%: 17 metastatic (94.4%) and 13 benign (76.5%) lesions. ROC curve analysis revealed maximal SUV of 3.1 as the optimum standard in differentiating metastatic from benign liver lesions (AUC=0.897, p<0.001, sensitivity 83.3%, specificity 94.1%). For small lesions less than 1 cm ln diameter (n=20), diagnostic accuracy of PET was comparable to that of MR. Conclusion: F-18 FDG PET showed good diagnostic performance in detecting liver metastasis from colorectal cancer, which was comparable to MR.

The expression of $p62^{c-myc}$ and $p21^{ras}$ can be seen in many solid tumor, but the pattern and incidence of expression were different according to organ, countries, and examiners, thus it is not definitely defined. Total 67 colorectal carcinoma in paraffin sections are analysed by immunohistochemically for evaluation of the $p62^{c-myc}$ and $p21^{ras}$ expression according to the age, sex, chief complaints, location, differentiation, modified Dukes stage, using the specific monoclonal antibodies. The results were summarized as follows : The age of patients ranged from 32 years to 82 years. The mean age was 57.6 years. The expression of $p62^{c-myc}$ and $p21^{ras}$ was not correlated with age. Male was 29 cases(43.3%) and female was 38 cases(56.7%). The male to female ratio was 1:1.31. The expression of $p21^{ras}$ was increased in female(p<0.05). Abdominal pain(43.7%) was the most frequent chief complaint. The most frequent tumor location was rectum(44.8%). The expression of $p62^{c-myc}$ was increased in the rectum(p<0.05). The 65 cases(97.0%) out of 67 cases showed positive reaction of $p62^{c-myc}$ in the nucleus, cytoplasmic membrane, and cytoplasm. The 62 cases(92.5%) out of 67 cases showed positive reaction of $p21^{ras}$ in the cytoplasmic membrane and cytoplasm. The positive rate of $p62^{c-myc}$ and $p21^{ras}$ was 97.0% and 91.4% in well differentiated adenocarcinoma, 100.0% and 95.0% in moderately differentiated adenocarcinoma, 90.0% and 90.0% in poorly differentiated adenocarcinoma, 100.0% and 100.0% in mucinous carcinoma. The positive rate of $p62^{c-myc}$ and $p21^{ras}$ was 94.1% and 88.2% in Dukes stage $B_1$, 96.0% and 96.0% in Dukes stage $B_2$, 100.0% and 100.0% in Dukes stage $C_1$, 100.0% and 88.9% in Dukes stage $C_2$, and 100.0% and 100.0% in Dukes stage D. The expression of $p62^{c-myc}$ in metastatic colorectal carcinoma showed diffuse and strongly positive reaction than primary colorectal carcinoma. The expression of $p21^{ras}$ in primary colorectal carcinoma showed diffuse and strongly positive reaction than metastatic colorectal carcinoma.

Cancer is now the leading fatal disease in every developed country. Due to very low efficiency of conventional cancer therapeutics and important aspect of quality of life (QOL), complementary/alternative medicine (CAM) has been accepted worldwide, especially by late-staged cancer patients. Oriental medicine traditionally has stressed not only the tumor itself but the body having cancer, improving cancer-related immunity and extending survival period. Herein, we report one case of a terminal staged rectal cancer patient having spread-metastasis but showing a meaningful clinical course of around four years with Oriental medicine therapies. This study aimed to report the clinical capacity of Oriental medicine for patients with cancerous disease, to help development of Oriental medicine-derived anticancer treatments.

Purpose: Colorectal ranter is the 4th leading cause of cancer death in Korea and the prevalence is increasing continuously. This study was aimed to figure out the problems through the clinical consideration about terminal colorectal ranter patients who had died in hospice unit. Methods: We retrospectively reviewed the medical records in 78 patients with colorectal ranter who had admitted, received palliative care, and died in a hospice unit between April 2003 and November 2006. Results: The median age of patients was 59.6 years with 45 men (58%) and 24 women (42%). The median survival in hospice and palliative care was 36 days. The median hospitalization was 22 days. The most prevalent reason for admission was pain (38 patients, 49%), and the most common symptom was also pain (70 patients, 90%). Forty eight patients (62%) took analgesics before hospice referral. Twenty seven patients (65%) of 45 patients with intestinal obstruction have been performed palliative procedures. Median survival of patients with palliative procedure was higher than that of no palliative procedure group (47 days vs 19 days, P-value=0.005). Conclusion: The duration of hospice and palliative care was not enough to care the terminal colorectal cancer. Therefore, we suggest that proper education and information should be provided to physician, patients and their family members for effective hospice and palliative care.

Purpose : To conduct nationwide surgery on the principles In radiotherapy for rectal center, and develop the framework of a database of Korean Patterns of Care Study. Materials and Methods : A consensus committee was established to develop a tool for measuring the Patterns in radiotherapy Protocols for rectal cancer. The Panel was composed of radiation oncologists from 18 hospitals in Seoul Wetropolltan area. The committee developed a survey format to analyze radiation oncologist's treatment principles for rectal cancer. The survey items developed for measuring the treatment principles were composed of 1) 8 eliglblllty criteria, 2) 20 Items for staging work-ups and prognostic factors, 3) 7 Items for principles of combined surgery and chemotherapy, 4) 9 patient set-ups, 5) 19 determining radiation fields, 6) S radiotherapy treatment pians, 7) 4 physicalilaboratory examination to monitor a patient's condition during treatment, and 8) 10 follow-up evaluations. These items were sent to radiation oncoioglsts In charge of gastrolntestlnal malignancies in all hospitals (48 hospitals) In Korea to which 30 replies were received (63$\%$). Results : Most of the surrey Items were replied to without no major between the repliers, but with the fellowing items only 50$\%$ of repliers were in agreement : 1) Indications of preoperative radiation, 2) use of endorectal ultrasound, CT scan, and bone scan for staging work-ups, 3) principles of combining chemotherapy with radiotherapy, 4) use of contrast material for small bowel delineation during simulation, 5) determination of field margins, and 6) use of CEA and colonoscopy for follow-up evaluations. Conclusions : The Items where considerable disaggrement was shown among the radiation oncologists seemed to make no serious difference In the treatment outcome, but a practical and reasonable consensus should be reached by the committee, with logical processes of agreement. These Items can be used for a basic database for the Patterns of Care Study, which will survey the practical radiotherapy Patterns for rectal cancer in Korea.
