Aortocaval fistula (ACF) occurs in <1% of all abdominal aortic aneurysms (AAAs), and in 3% to 7% of all ruptured AAAs. The triad of clinical findings of AAA with ACF are abdominal pain, abdominal machinery bruit, and a pulsating abdominal mass. Other findings include pelvic venous hypertension (hematuria, oliguria, scrotal edema), lower-limb edema with or without arterial insufficiency or venous thrombus, shock, congestive heart failure, and cardiac arrest. Surgery is the main treatment modality. We report successful surgical treatment in a patient with a ruptured AAA with ACF who presented with cardiogenic shock.

Purpose : The adjuvant postoperative radiotherapy has been usually applied to the patients with unfavorable prognostic factors after radical operation in early cervical cancer. We focused on the evaluation of the survival status and failure patterns of the patients with postoperative radiotherapy. Materials and Methods : We retrospectively analyzed ninety patients with FIGO stage IB and IIA cervix cancer who received postoperative pelvic irradiation at Chonnam University Hospital between August 1985 and December 1988, Seventy-eight patients had adequate follow-up information for survival analysis. Median follow-up time of these patients was 64 months. Results : The 5 year overall and disease free survival rate of ninety patients was $80.0\%$ and $80.2\%$, respectively. The prognostic significance to the survival was determined by multivariate analysis. Adequacy of resection margin(p=0.005) and lymph node status(p=0.005) appeared to be independent prognostic factors. Recurrence occurred in 13 patients, 5 in the pelvis and 8 at distant sites. The median time to recurrence was 19 months(range:3-39 months). The pelvic recurrence was more prevalent in the group of patients with adenocarcinoma, depth of stromal invasion more than 10mm and use of chemotherapy. The distant failure was more prevalent in the group of positive resection margin or positive lymph node with statistical significance. Conclusion : Patients with pelvic lymph node or surgical margin involvement clearly constitute a high risk group in this analysis and should be considered as candidates for some form of adjuvant therapy.

One hundred and twenty six patients with early uterine cervical cancer who had been treated at Departmen of Radiation Oncology of Korea University Hospital from Jan.1981 to Dec.1988 were analysed retrospectively by the treatment result and pattern of of failures. All patients had stage Ia to IIa disease and were grouped whether they had combination of operation and postop irradiation or radiation therapy alone. 1) Sixty six patients belonged to the combination treatment group and 60 patients to the radiation alone group. 2) Combination group consisted of $18.1\%$(12/66) stage Ia, $71.2\%$(47/66) stage Ib and $10.6\%$ (7/66) stage IIa patients. There were no stage Ia, 18.8$\%$(l1/60) stage Ib and 81.6$\%$(49/60) stage IIa patients for RT alone gronp. 3) There were total 23$\%$(29/126) treatment failures,13 patients in combination group and 16 patients in RT alone group. In 66 patients of combination group, they were found to have 5 locoregional failures, 7 distant failures and 1 at both sites. In 60 patients of RT alone group, 9 locoreginal failure and 7 distant failures occured. Eighty six percent (25/29) of total failures appeared within 18 month after completion of treatment. About 60$\%$ of the patients with regional recurrences which were located at pelvic side wall or pelvic lymph nodes paesented their recurrent disease after 1 year of completion of treatment, whereas same percent of distant failures appeared within 6 month. 5) In RT alone group, the first sites of distant failure were mostly para-aortic lymph node and/or left supraclavicular lymph node (71.4$\%$,5/7). In combination group, various sites such as inguinal lymph node, mediastinal lymph node, liver, lung and bone appeared first or at the same time with para-aortic and supraclavicular lymph node metastasis. 6) Logistic regression analysis was done for multivariate analysis of the factors contributing to locoregional and distant failures. In combination group, adequacy of the resection margin and the presence of positive pelvic node were found to be the most significant factors (p=0.0423 & 0.0060 respectively). In RT alone group, less than complete regression of the tumor at the end of treatment was the only significant contributing factor for the treatment failures (p=0.0013) with good liklihood ratio.

To evaluate the role of postoperative pelvic radiation therapy in rectal cancer, a retrospective analysis was done on 189 patients with modified Astler-Coiler stages B2+3, Cl , and C2+3 who were treated from February 1979 to June 1980. Forty-seven patients were staged as B2+3,17 as Cl, and 125 as C2+3. As a curative resection,41 received low anterior resection,143 received abdomino-perineal resection, and five received pelvic exenteration. The survival and disease-free survival rates of the total patients at five year were $45.3\%\;and\;44.1\%$, respectively. The stage was an important prognostic factor for survival and disease-free survival: the survival rates at five year were $63.4\%$ in stage B2+3, $62.4\%$ in C1, and $37.2\%$ in C2+3 (p<0.005): the disease-free survival rates at five year were $55.7\%$ in B2+3, $65.7\%$ in C1, and $30.4\%$ in C2+3, respectively (p<0.01). The liver was the most frequently involved organ of recurrence followed by the lung and the perineum. The patients who received low anterior resection achieved better disease-free survival but were more prone to late radiation bowel morbidities than those who received abdominoperineal resection. Postperative Pelvic radiation therapy Proved to be effective in locoregional disease control but did not prevent the appearance of distant metastasis, which was of major concern in advanced stages. Patterns of treatment failure, and factros relating to radiation morbidity are discussed, and therapeutic options for better results are proposed.

226 patients with carcinoma of the uterine cervix treated with curative radiation therapy at the Department of Therapeutic Radiology, Dongsan hospital, Keimyung university, School of medicine, from July,1988 to May,1991 were evaluated. The patients with all stages of the disease were included in this study. The maximum and mean follow up durations were 60 and 43 months. The radiation therapy consisted of external irradiation to the whole pelvis (2700~4500 cGy) and boost parametrial doses (for a total of 4500~6300 cGy)with midline shild $(4{\times}10\;cm),$ and combined with intracavitary irradiation (5700~7500 cGy to point A). The distribution of patients according to the stage was as follows: stage IB 37 $(16.4\%),$ stage IIA 91 $(40.3\%),$ stage IIB 58 $(25.7\%),$ stage III 32 $(13.8\%),$ stage IV 8 $(3.5\%).$ The overall failure rate was $23.9\%$ (54 patients). The failure rate increased as a function of stage from $13.5\%$ in stage IB to $15.4\%$ in stage IIA, $25.9\%$ in stage IIB, $46.9\%$ in stage III, and $62.5\%$ in stage UV. The pelvic failure alone were 32 patients and 11 patients were as a components of other failure, and remaining 11 patients had distant metastasis only. Among the 43 patients of locoregional failure,28 patients were not controlled initially and in other words nearly half of total failures were due to residual tumor. The mean medial paracervical (point A) doses were 6700 cGy in stage IIB,7200 cGy in stage IIA,7450 cGy in stage IIB,7600 cGy in stage III and 8100 cGy in stage IV. The medial paracervical doses showed some correlation with tumor control rate in early stage of disease (stage Ib, IIA), but there were higher central failure rate in advanced stage in spite of higher paracervical doses. In advanced stage, failure were not reduced by simple increment of paracervical doses. To improve a locoregional control rate in advanced stages, it is necessary to give additional treatment such as concomitant chemoradiation.

Purpose: To retrospectively assess the advantages and side effects of prophylactic Paraaortic irradiation in cervical cancer patients with common iliac nodal involvement, the results for survival, patterns of failure, and treatment-related toxicity. Materials and Methods: From May 1985 to October 2004, 909 patients with cervical carcinoma received postoperative radiotherapy at the Seoul National University Hospital. Among them, 54 patients with positive common iliac nodes on pathology and negative Paraaortic node were included in the study. In addition, 44 patients received standard pelvic irradiation delivered 50.4 Gy per 28 fractions (standard irradiation group), and chemotherapy was combined in 16 of them. The other 10 patients received pelvic irradiation at a dose of 50.4 Gy per 28 fractions in addition to Paraaortic irradiation at 45 Gy per 25 fractions (extended irradiation group). In addition, all of them received chemotherapy in combination with radiation. Follow-up times for pelvic and Paraaortic irradiation ranged from 6 to 201 months (median follow-up time, 58 months) and 21 to 58 months (median follow-up time, 47 months), respectively. Results: The 4-year overall survival, disease free survival, and distant metastasis free survival in the standard irradiation group and extended irradiation group were 67.2% vs. 90.0% (p=0.291), 59.0% vs. 70.0% (p=0.568) and 67.5% vs. 90.0% (p=0.196), respectively. The most common site of first failure for the standard irradiation group was the paraaortic lymph node, while no paraaortic failure was observed in the extended irradiation group. Relatively, hematologic toxicity grade 3 or greater was common in the extended irradiation group (2/10 extended vs. 2/44 standard), while gastrointestinal toxicity of grade 3 or greater was lower (2/10 extended vs. 6/44 standard), and urologic toxicity of grade 3 or greater was observed in the standard irradition group only (0/10 vs. 3/44). Conclusion: Concurrent chemotherapy and prophylactic Paraaortic irradiation in patients with common iliac nodal involvement showed slightly improved clinical outcomes aside from increased hematologic toxicity, which was statistically insignificant. Considering the relatively small number of patients and short follow-up times, additional studies are needed to obtain more conclusive outcomes.

Purpose : This is a retrospective analysis for pattern of failure, survival rate and prognostic factors of 114 patients with histologically proven invasive cancer of the uterine cervix treated with definitive irradiation. Materials and Methods : One hundred fourteen patients with invasive carcinoma of the cervix were treated with a combination of intracavitary irradiation using Fletcher-Suit applicator and external beam irradiation by 6MV X-ray at the Ewha Womans University Hospital between March 1982 and Mar 1990. The median age was 53 years(range:30-77 years). FIGO stage distribution was 19 for IB, 23 for IIA, 42 for IIB, 12 for IIIA and 18 for IIIB. Summation dose of external beam and intracavitary irradiation to point A was 80-90 Gy(median:8580 cGy) in early stage(IB-IIA) and 85-100 Gy(median:8850 cGy) in advanced stage(IIB-IIIB). Kaplan-Meier method was used to estimate the survival rate and multivariate analysis for progrostic factors was performed using the Log likelihood for Weibull Results : The pelvic failure rates by stage were $10.5{\%}$ for IB. $8.7{\%}$ for IIA, $23.8{\%}$ for IIB, $50.0{\%}$ for IIIA and $38.9{\%}$ for IIIB. The rate of distant metastasis by stage were $0{\%}$ for IB, $8.7{\%}$ for IIA, $4.8{\%}$ for IIB. $0{\%}$ for IIIA and $11.1{\%}$ for IIIB. The time of failure was from 3 to 50 months and with median of 15 months after completion of radiation therapy. There was no significant coorelation between dose to point A($\leq$90 Gy vs >90 Gy) and pelvic tumor control(P>0.05). Incidence rates of grade 2 rectal and bladder complications were $3.5{\%}$(4/114) and $7{\%}$(8/114), respectively and 1 patient had sigmoid colon obstruction and 1 patient had severe cystitis. Overall 5-year survival rate was $70.5{\%}$ and disease-free survival rate was $53.6{\%}$. Overall 5-year survival rate by stage was $100{\%}$ for IB, $76.9{\%}$ for IIA, $77.6{\%}$ for IIB $87.5{\%}$ for IIIA and $69.1{\%}$ for IIIB. Five-rear disease-free survival rate by stage was $81.3{\%}$ for IB, $67.9{\%}$ for IIA, $46.8{\%}$ for IIB, $45.4{\%}$ for IIIA and $34.4{\%}$ for IIIB. The prognostic factors for disease-free survival rate by multivariate analysis was performance status(p= 0.0063) and response rate after completion of radiation therapy(p= 0.0026) but stage, age and radiation dose to point A were not siginificant. Conclusion : The result of radiation therapy for early stage of the uterine cervix cancer was relatively good but local control rate and survival rate in advanced stage were poor inspite of high dose irradiation to point A above 90 Gy. Prospective randomized studies are recommended to establish optimal tumor doses for various stages and volume of carcinoma of uterine cervix, And ajuvant chemotherapy or radiation-sensitizing agents must be considered to increase the pelvic control and survival rate in advanced cancer of uterine cervix.

Purpose: To assess the clinical efficacy and toxicity of whole pelvic intensity-modulated radiotherapy (WP-IMRT) for high-risk prostate cancer. Materials and Methods: Patients with high-risk prostate cancer treated between 2008 and 2013 were reviewed. The study included patients who had undergone WP-IMRT with image guidance using electronic portal imaging devices and/or cone-beam computed tomography. The endorectal balloon was used in 93% of patients. Patients received either 46 Gy to the whole pelvis plus a boost of up to 76 Gy to the prostate in 2 Gy daily fractions, or 44 Gy to the whole pelvis plus a boost of up to 72.6 Gy to the prostate in 2.2 Gy fractions. Results: The study cohort included 70 patients, of whom 55 (78%) had a Gleason score of 8 to 10 and 50 (71%) had a prostate-specific antigen level > 20 ng/mL. The androgen deprivation therapy was combined in 62 patients. The biochemical failure-free survival rate was 86.7% at 2 years. Acute any grade gastrointestinal (GI) and genitourinary (GU) toxicity rates were 47% and 73%, respectively. The actuarial rate of late grade 2 or worse toxicity at 2 years was 12.9% for GI, and 5.7% for GU with no late grade 4 toxicity. Conclusion: WP-IMRT was well tolerated with no severe acute or late toxicities, resulting in at least similar biochemical control to that of the historic control group with a small field. The long-term efficacy and toxicity will be assessed in the future, and a prospective randomized trial is needed to verify these findings.

In recent days, family planning is not only a problem limitted to our country but an important problem for the while world to solve. Up to present, various methods of sterilization have been developed for population control. When a patient with a previous tubal sterilization by operative method develops any symptoms and signs of pregnancy, we strongly consider it ectopic pregnancy and intrauterine pregnancy. As the cause of sterilization failure, we think that the tubal loop sloughs away and tubal ends either unite and recanalization results or heal and failure of union results in fistula. This present study considered of the 34 cases of ectopic pregnancies and 2 cases of intrauterine pregnancies after tubal sterilization by laparoscopy and Pomeroy's method, at the Dept. of Gynecol. in Kyung Hee University Hospital, during 6 years from Jan. 1977 to Dec. 1982. Authors take result in this study retrospectively. 1. Mean age was 33.7 years for the laparoscopic tubal sterilization group, 31.5 years for the Pomeroy tubal sterilization group. 2. The number of mean gravida and parity at the sterilization was 4.9, 2.8 for the laparoscopic tubal sterilization group, 4.2, 2.2 for the Pomeroy tubal sterilization group, :respectively. 3. The number of mean artificial abortion at the sterilization was all 2.2 for the laparoscopic and Pomeroy tubal sterilization groups. 4. Mean intervals from the tubal surgery to the incidental pregnancy was 3.2 years for the laparoscopic tubal sterilization group, and 3.8 years for the Pomeroy tubal sterilization group. 5. 63.3% of the laparoscopic tubal sterilization group had problem of inadequate tubal ligation, in comparison to having no inadequate problem in the Pomeroy tubal sterilization group. 6. The previous tubal sterilized scar was found to be 6 cases (17.6%) of inner portion, 15 cases (44.4%) of midportion, 13 cases (38.2%) of outer portion at the time of operation. The tubal site of ectopic pregnancy was found to be 23 cases (67.6%) of ampullary portion,S cases ( 4.7%) of isthmic and fimbrial portion, respectively. 7. The causes of table sterilization failure were, in order of frequency, technical error (19 cases), fistula formation (6 cases) and recanalization (5 cases) for the laparoscopic tubal sterilization group and fistula formation (2 cases), technical error (l case), recanalization (l case) fo the Pomeroy tubal sterilization group. 8. As the new applicated contraceptive method in incidental pregnant patient, Authors used 2 gravigard insertion for the two intrauterine pregnancy and 34 Pomeroys' tubal ligation, 2 total abdominal hysterectomy (due to associated pelvic inflammatory disease) for the 36 tubal pregnancy.
