BACKGROUND/AIMS: Guidelines for current postoperative colonoscopic surveillance are not specified in colorectal cancer (CRC) patients with synchronous adenoma (SA). We performed this retrospective study to determine the postoperative colonoscopic surveillance interval for the CRC patients with SA. METHODS: One hundred and twenty-four CRC patients with SA (SA-group) and the same number of patients without SA (NSA-group) were selected from our database. Two groups were matched by the stage of CRC. Median colonoscopic surveillance period was 55 (12-99) months. The colonoscopic surveillance frequency and interval were similar between the two groups. RESULTS: Mean age was higher and male was more frequent in SA-group than NSA-group (p= 0.0001). The incidence of missed adenoma, advanced missed adenoma and metachronous adenoma (MA) were higher in SA-group (30.8% vs. 5.8% at 1st yr., p=0.0001; 4.4% vs. 0%, p=0.0001; 31.1% vs. 9.1% at 2nd yr., p=0.016) during the first consecutive two years of surveillance. The MA- and advanced-MA-free survival rate were lower in SA-group (24.6% vs. 6.6%, p=0.0001; 4.1% vs. 0%, p=0.02) during three years after surgery. Dysplasia of the SA (p=0.04; OR, 110.3; 95% CI, 1.13-10742.6) and presence of missed adenoma (p=0.036; OR, 43.6; 95% CI, 1.28-1490.1) were risk factors for the advanced MA on a multivariate analysis in SA-group. CONCLUSIONS: Postoperative colonoscopic surveillance at first year after surgery is warranted in CRC patients with SA.

BACKGROUND/AIMS: It have been reported that operative mortality and morbidity rate rise significantly when emergency cholecystectomy is performed in critically ill patients with acute cholecystitis(AC), and many studies have also concluded that delayed or interval laparoscopic cholecystectomy(LC) in patients with AC demonstrated high conversion rate and complication rate compared with early LC. However, if the acutely inflamed gallbladder(GB) is decompressed by emergent percutaneous gallbladder drainage(PGBD), it may decrease the technical difficulty of LC allowing successful delayed LC or may decrease the wound complication of delayed open cholecystectomy, when the patient is in better condition. The purpose of this retrospective study was to assess the outcome of delayed cholecystectomy focused on LC following PGBD in patients with AC METHODS: A total of 181 patients with AC were divided into PGBD(n= 66) and non-PGBD group(n= 115), and each group were subdivided into PGBD-delayed LC(after 72 hours of admission, n= 32), PGBD-open cholecystectomy(n= 20), non-PGBD-early LC(within 72 hours of admission, n= 40), non- PGBD-delayed LC(n= 17), non PGBD-open cholecystectomy group(n= 58) and others. PGBD group had higher incidence of comorbidity compared with non-PGBD group. Outcomes of cholecystectomy was assessed by conversion rate and morbidity rate(chi2 test), LC time and hospital stay(median test) for LC, and morbidity for open cholecystectomy in PGBD group compared with those of non PGBD group. RESULTS: PGBD promptly relieved of symptom of AC in 94 % of patients and showed 3 % of technical failure and 4.5 % of complication rate. Compared with non PGBD-early and delayed LC group, the PGBD-delayed LC group showed longer LC time(median 110 min vs 82.5, p < 0.05, vs 95 min), a little lower conversion rate(12.5 % vs 22.5 % vs 17.6 %), similar morbidity rate(19% vs 17.5 % vs 29 %) and prolonged total hospital stay(median 12.5 days vs 7 days, p < 0.001, vs 10 days). In open cholecystectomy series, PGBD group showed lower morbidity rate compared with non PGBD group(5% vs 24 %, p < 0.05) CONCLUSION: Unlike to open cholecystectomy series, PGBD did not significantly improve the outcome of LC for AC as assessed by conversion and morbidity rate and hospital stay compared with non PGBD. Thus we can conclude that although PGBD is a safe and effective emergency procedure for AC, it should be limited to higher risk group such as elderly or critically ill patients and to acalculous cholecystitis.

PURPOSE: To report on the changes in the patterns of care and survival over time for esthesioneuroblastoma. MATERIALS AND METHODS: We retrospectively analyzed 42 previously untreated and histologically confirmed esthesioneuroblastoma patients seen between March 1989 and June 2007. According to Kadish's classification, 3 patients (7%) were stage A, 6 (14%) at stage B, and 33 (79%) at stage C. Of the 33 Kadish C patients, 19 and 14 patients were treated from 1989 through 2000 and from 2001 through 2007, respectively. Treatment included surgical resection, radiotherapy, chemotherapy, or a combination of these methods. Chemotherapy was administered to 8 of 19 patients (42%) seen from 1989 through 2000, whereas all of the 14 patients seen from 2001 through 2007 received chemotherapy (p<0.001). No patient was treated by three-dimensional conformal radiotherapy (3D-CRT) from 1989 through 2000, however 8 of 14 patients (67%) seen from 2001 through 2007 underwent 3D-CRT (p<0.001). The median follow-up time for surviving patients was 6.5 years (range, 2.2~15.8 years). RESULTS: The 5-year overall survival (OS) and progression-free survival (PFS) rates for the entire cohort were 53% and 39%, respectively. The 5-year OS was 100% for Kadish stages A or B and 39% for stage C (p=0.007). For patients with stage C disease who were treated from 1989 to 2000 and from 2001 to 2007, the 5-year OS rate was 26% and 59% (p=0.029), respectively and the corresponding 5-year PFS rate was 16% and 46% (p=0.001), respectively. Intraorbital extension and treatment era (1989~2000 vs. 2001~2007) were found as independent factors for OS and PFS in a multivariate analyses. CONCLUSION: The results of this study suggest that treatment era, which features a distinction in treatment modality and technique with the introduction of 3D-CRT, may be the cause of improved OS and PFS in Kadish stage C patients. To achieve better outcomes for patients with Kadish stage C, combined chemoradiotherapy, especially 3D-CRT, is recommended in addition to surgery.

Carcinoma of the prostate is a common malignancy affecting elderly men. Lung metastasis from prostate cancer occurs frequently, but tumor metastasis to the central bronchi that clinically mimics primary bronchogenic carcinoma are very rare. We report a 73-year old man with endobronchial metastasis from prostatic carcinoma presented with respiratory symptom cough. Diagnosis of issues taken from materials which were used for bronchoscopic biopsy and prostate biopsy and immunohistochemical staining for prostate specific antigen(PSA) confirmed a case of endobronchial metastasis from prostatic carcinoma. Hormonal therapy(LHRH agonist) was applied to this patient.

Purpose: Nasopharyngeal cancer (NPC) has a higher prevalence of regional nodal metastasis than other head and neck cancers; however, level IB lymph node involvement is rare. We evaluated the safety and feasibility of level IB-sparing radiotherapy (RT) for NPC patients. Materials and Methods: We retrospectively reviewed 236 patients with NPC who underwent definitive intensity-modulated RT with or without chemotherapy between 2004 and 2018. Of them, 212 received IB-sparing RT, and 24 received non-IB-sparing RT. We conducted a propensity score matching analysis to compare treatment outcomes according to IB-sparing status. In addition, dosimetric analysis of the salivary glands was performed to identify the relationship between xerostomia and the IB-sparing RT. Results: The median follow-up duration was 78 months (range, 7 to 194 months). Local, regional, and distant recurrences were observed in 11.9%, 6.8%, and 16.1% of patients, respectively. Of the 16 patients with regional recurrence, 14 underwent IB-sparing RT. The most common site categorization of regional recurrence was level II (75%), followed by retropharyngeal lymph nodes (43.8%); however, there was no recurrence at level IB. In the matched cohorts, IB-sparing RT was not significantly related to treatment outcomes. However, IB-sparing RT patients received a significantly lower mean ipsilateral and contralateral submandibular glands doses (all, p < 0.001) and had a lower incidence of chronic xerostomia compared with non-IB-sparing RT patients (p = 0.006). Conclusion Our results demonstrated that IB-sparing RT is sufficiently safe and feasible for treating NPC. To reduce the occurrence of xerostomia, IB-sparing RT should be considered without compromising target coverage.

PURPOSE: There has been no definitive randomized study to identify the optimal therapeutic regimen for treating squamous cell carcinoma of tonsil. The purpose of this study was to retrospectively evaluate the treatment outcome according to various combinations of surgery, radiation therapy and chemotherapy. MATERIALS AND METHODS: Fifty-six patients with tonsillar carcinoma, who were treated at Seoul National University Hospital from March 1985 to August 2001, were the subjects of this study. Twenty-one patients received surgery followed by radiation therapy (SRT), 16 patients underwent radiation therapy alone (RT), and 19 patients received neoadjuvant chemotherapy and radiation therapy (CRT). The median radiation dose was 66.6 Gy for the SRT group and 70.2 Gy for the RT and CRT groups. Surgery comprised extended tonsillectomy and modified radical neck dissection of the involved neck. Cisplatin and 5-fluorouracil were used every three weeks for 3 cycles in the SRT group. The median follow-up was 73.2 months. RESULTS: The distribution of T-stage was 4 cases of T1, 14 cases of T2, 1 case of T3 and 2 cases of T4 staging in the SRT group, 2 cases of T1, 6 cases of T2, 5 cases of T3 and 3 cases of T4 staging in the RT group and 0 cases of T1, 7 cases of T2, 9 cases of T3 and 3 cases of T4 staging in the CRT group. The distribution of N-stage was 5 cases of N0, 2 cases of N1, 13 cases of N2 and 1 case of N3 staging in the SRT group, 6 cases of N0, 5 cases of N1, 5 cases of N2 and 0 cases of N3 staging in the RT group, and 2 cases of N0, and 7 cases of N1, 9 cases of N2 and 1 case of N3 staging in the CRT group. The five-year overall survival rate (OSR) for all patients was 78%. The five-year OSR was 80% for the SRT group, 71% for the RT group, and 80% for the CRT group (p=ns). The five-year disease-free survival rate was 93% for the CRT group and 71% for the RT group (p=0.017). Four patients developed local failure and one patient failed at a regional site in the RT group, and one patient failed at a primary site in the CRT group. The five-year DFS was 84% for patients who had undergone neck dissection and 76% for patients who had not undergone neck dissection (p=ns). Treatment-related complications of grade 3 or 4 occurred in 15 patients, and the incidence of complication was not different between each of the treatment methods. CONCLUSION: Although the patients with more advanced T stage were included in the RT and CRT groups, the OSR was not statistically different according to the treatment methods. In the radical radiation therapy group, the addition of neoadjuvant chemotherapy showed an improvement in the disease-free survival. Because of the retrospective nature of our study and the small number of patients, this study cannot draw any definite conclusions, but it suggests that radiation therapy with chemotherapy can be a good alternative option for squamous cell carcinoma of tonsil. Controlled randomized study is necessary to confirm this hypothesis.

Adalimumab, a recombinant human IgG monoclonal antibody, selectively blocks tumor necrosis factor-alpha (TNF-alpha) and has been successfully used in the treatment of immune-mediated diseases. In particular, its efficacy has been proven in the treatment of rheumatoid arthritis, spondylarthritis, lymphoproliferative diseases and inflammatory bowel disease. Its use has also been studied for the treatment of psoriasis and yet, paradoxically, cases of new onset or exacerbation of psoriasis continue to increase in patients undergoing treatment with anti TNF-alpha agents. A 51-year-old woman had arthritis for a year and was diagnosed with psoriatic arthritis. After she had received adalimumab for psoriatic arthritis five times during one year, erythematous eruptions were found on her entire body. She then stopped adalimumab therapy for two months, although her skin lesions did not resolve. The patient was diagnosed with psoriasis through biopsy and began using cyclosporine, a topical steroid used for treatment of psoriasis.

OBJECTIVES: The aim of this study is to develop guidelines for psychosocial treatment of alcohol use disorder. METHODS: According to the ADAPTE manual, the Korean alcohol use disorder treatment guidelines were developed by the guideline development committee. Recommendations from foreign guidelines were evaluated regarding the applicability and acceptability to domestic circumstances. In addition, a survey from experts was conducted, along with a review of Korean literature. By these means, recommendations of psychosocial treatment for alcohol use disorder were established. RESULTS: The main findings of the survey were as follows : 1) Although Group therapy was not recommended by foreign clinical guidelines, it was considered as a first-line treatment by Korean experts. 2) Among many psychosocial treatment programs, cognitive behavior therapy (CBT), coping skills training, 12-step facilitation, and Group therapy were commonly used programs in Korea. Finally, the following treatment methods were selected for recommendations : Group therapy, motivational enhancement treatment, CBT, behavioral self-management, alcoholic anonymous, 12-step facilitation, psychodynamic psychotherapy, psychoeducational intervention, continuous case management, and community residential rehabilitation program. CONCLUSION: Just as in treatment of chronic diseases such as hypertension, continuity is important for management of alcohol use disorder. Therefore, not only pharmacological treatment but also psychosocial treatment should be provided comprehensively after treatment of acute withdrawal symptoms.

PURPOSE: This retrospective study was conducted to assess outcome and to determine the prognostic factors in patients with a desmoid tumor treated with postoperative radiotherapy. MATERIALS AND METHODS: Twenty-seven patients with a desmoid tumor who were treated with postoperative radiotherapy between June 1984 and October 2005 were analyzed. There were 13 male and 14 female patients. The age of the patients ranged from 3 to 79 years (median age, 28 years). Tumors were located in an extra-abdominal area (21 cases), and in the abdominal walls (6 cases). The tumor size ranged from 2.5 to 25 cm (median size, 7.5 cm) in the largest linear dimension. Thirteen cases received radiotherapy after initial surgery, and 14 recurrent cases received radiotherapy after additional surgery. The total radiation dose given was 45~66 Gy (median dose, 59.4 Gy), and the fraction size was 1.8~2.0 Gy. RESULTS: The median follow-up period was 61 months (range, 12~203 months). Two patients developed local progression and six patients experienced local recurrence. The 5-year disease-free survival rate and the 5-year progression-free survival rate were 61% and 70%, respectively. Wide local excision was associated with better disease free survival with statistical significance (p=0.028). Radiotherapy after initial surgery (p=0.046) and a higher radiation dose of more than 60 Gy (p=0.049) were associated with better progression free survival with statistical significance. At the time of the last follow-up, the number of additional surgeries was higher in patients that received radiotherapy after reoperation (p<0.001). CONCLUSION: Radiotherapy after the initial operation improved local control and decreased the number of subsequent operations. Thus, postoperative radiotherapy after an initial operation is recommended in patients with a high risk of recurrence for a desmoid tumor.

OBJECTIVES: Renal transplantation has become the ther apy of choice for patients suffering from end-stage renal disease. But because of progressive disparity between the number of patients in needs of a transplant and the num ber of ideal kidneys available for transplantation, increas ing numbers of kidneys are recovered for transplantation from donors that are not considered ideal, especially from donors over the age of 55. In country such as Korea, the number of cadaveric transplants is limited due to cultural and religious prejudices of the population, poor legal def inition and deficient organization of cadaveric donor work-up. Therefore the main source is living related donors(LRD), especially the parent. But in Korea, there is few reports about the influence of donor age on outcome in living related kidney transplantation. Thus we per formed this study to estimate the influence of donor age in itself on the outcome of the one HLA-haplotype mis matched living related kidney transplantation. METHODS: The effect of donor age on the outcome of One HLA-haplotype mismatched living related kidney transplantation was studied in 71 recipients who under went kidney transplantation from January 1981 to March 1995. The outcomes of 25 recipients from the older age group(> OR =55 years: Group A) and 46 recipients from the younger age group(<55 years: Group B) were retro spectively reviewed. Patient death with a functioning graft was considered graft loss. RESULTS: Demographic characteristics between 2 groups were similar. The 1-year and 3-year patient survival rates in recipients(group A and B) were similar regard less of donor age(96.0% and 90.8% vs.97.4% and 90.3%, respectively). The 1-year and 3-year graft survival rates in recipients(group A and B) were not significantly dif ferent (91.4% and 63.9% vs 92.7% and 79.3%, respec tively). The mean levels of serum creatinine at discharge were significantly higher in group A. Short-term and intermediate-term renal function, as assessed by serum creatinine, was inferior in the group A throughout the follow-up periods of 3 years. The causes of graft loss in the first 3 years after transplantation were irreversible rejection(71%) and the patient death with functioning graft(29%) in group A, while the causes of graft loss in group B were irreversible rejection(50%), patient death with a functioning graft(40%) and technical reason(10%). CONCLUSION: These results of our analysis suggest that similar outcome can be achieved after living related renal transplantation from older donor. Therefore the kid neys may be used from donors over 55 years old on con dition that the donors undergo complete and exhaustive work-up.
