Background: To compare the pathological findings and oncologic outcomes of stage IA cervical carcinoma patients, between adenocarcinoma and squamous cell carcinoma cases. Materials and Methods: A total of 151 medical records of stage IA cervical carcinoma patients undergoing primary surgical treatment during 2006-2013 were reviewed. Information from pathological diagnosis and recurrence rates were compared with descriptive statistical analysis. The Kaplan-Meier method and Cox proportional hazards model were used for survival analysis. Results: The median age was 48.9 years. There was no significant difference in rates of lymph node, parametrium, uterine, vaginal, or ovarian metastasis, when comparing adenocarcinoma with squamous cell carcinoma. Overall recurrence rates of adenocarcinoma (5.7%) and squamous cell carcinoma (2.6%) were not statistically significant different, even when stratified by stage. When comparing progression free survival with squamous cell carcinoma, adenocarcinoma had an HR of 0.448 (0.073-2.746), p=0.386. Conclusions: Microinvasive adenocarcinoma of cervix has similar rate of extracervical involvement and oncologic outcomes to squamous cell carcinoma.

Aggressive angiomyxoma is a rare neoplasm that arise from soft tissue of the perineum and usually affects young woman. It has a high risk of local recurrence due to infiltrative lesion. This tumor should be distinguished from benign and malignant tumor or tumor like lesion of the perineum. We experienced a case of an aggressive angiomyxoma on soft tissue of the vaginal wall in 43-year-old woman and reported it with a brief review of literature.

Rectovaginal fistula, which can arise after an injury to the vaginal canal or rectum, is a troublesome obstacle for patients' everyday life. In most cases, it can be covered with a local flap, but previous radiation therapy increases the recurrence rate, making it especially difficult to cure. As the application of stromal vascular fraction (SVF) obtained from enzymatically digested autologous adipose tissue has become increasingly common, several reports have advocated its effectiveness for the treatment of refractory wounds. In light of the angiogenic, regenerative characteristics of SVF, it was incorporated as a treatment option in two cases of rectovaginal fistula discussed here. As described in this report, irradiated rectovaginal fistulas in rectal cancer patients were successfully treated with SVF injection, and we suggest SVF as a feasible treatment option for cases of rectovaginal fistula that would otherwise be very difficult to cure.

Background: Postoperative adjuvant radiotherapy (RT) in the management of early stage endometrial cancer (EC) is still controversial. Here we report our institutional experience with patients who received postoperative RT for stage I-II EC over a period of 35 years and assess potential predictors of local recurrence (LR), distant metastasis (DM), and overall survival (OS). Materials and Methods: A total of 188 patients undergoing postoperative RT for stage IA-II EC between 1977 and 2012 were evaluated. Some 96 received median 46 Gy whole pelvic radiotherapy (WPRT) (range: 40-60 Gy), 37 were given WPRT with vaginal cuff therapy (VCT), and 55 received only VCT either with brachytherapy (BT) or stereotactic body radiotherapy (SBRT). Chemotherapy was given to 5 patients with uterine papillary serous carcinoma (UPSC). Logistic regression analysis was used to assess the effect of clinicopathological factors on LR, DM, and OS. Results: Median follow-up time was 11 years (range: 1-35 years). At the time of analysis, 34 patients were not alive. Of the 15 patients with LR, 7 (46.7%) recurred in the vaginal stump, 5 (33.3%) in the pelvic region, and 3 (20%) in the paraaortic nodal region, while 12 had distant metastasis. UPSC histology (p=0.027), sole VCT (p=0.041), high histologic grade (p=0.034), and age ${\geq}71$ (p=0.04) were poor prognostic factors on univariate analysis. Conclusions: In our patients receiving radiotherapy for early-stage EC, grade III disease and age ${\geq}71$ were associated with shorter OS whereas UPSC histology was an independent predictor for both LR and DM.

Background: To evaluate treatment outcomes of patients with stage I-III endometrial cancer treated with postoperative radiation. Materials and Methods: A retrospective review of 166 endometrial cancer patients, undergoing surgery and postoperative radiotherapy at Siriraj Hospital from 2005-2008 was performed. Pathology was reviewed. Results of treatment were reported with 5-year loco-regional recurrence free survival (LRRFS), 5-year overall survival (OS), patterns of failure and toxicity, and according to stage and risk groups. Results: Median follow up time was 62.8 months. Pathological changes were found in 36.3% of the patients after central reviews, leading to 19% changes in risk groups. Most of the patients (83.7%) received pelvic radiation (PRT) and vaginal brachytherapy (VBT). Five-year LRRFS and OS of all patients were 94.9% and 85.5%, respectively. There was no recurrence or death in low and low-intermediate risk groups. For the high-intermediate risk group, 5-year LRRFS and OS were 96.2% and 90.8%, respectively, and for the high risk group 90.5% and 71%. Late grade 3 and 5 gastrointestinal toxicity was found in 3% and 1.2% of patients, respectively. All of them received PRT 5,000 cGy in 25 fractions. Conclusions: Low and intermediate risk patients had good results with surgery and adjuvant radiation therapy. For high risk patients, postoperative radiation therapy alone appeared to be inadequate as the most common pattern of failure was distant metastasis.

Background: Most patients with endometrial cancer have stage I disease. Adjuvant therapy in stage IB (formerly IC) endometrial cancer is controversial, treatment options including observation or brachytherapy/radiotherapy in grade 1-3 patients with or without chemotherapy. The purpose of this study was to assess the outcomes of our patients with stage IB endometrioid endometrial cancer. Materials and Methods: Sixty two patients with stage IB endometrial cancer and endometrioid histology were retrospectively evaluated. All patients were initially treated surgically by the same surgeon with comprehensive staging, i.e. total abdominal hysterectomy, bilateral salphingooopherectomy, bilateral pelvic and paraaortic lymph node dissection and omentectomy. Adjuvant radiotherapy was discussed with patients and utilized by those who accepted. Adjuvant chemotherapy was not given to any of the patients. Results: Median age was 62 (range, 42-95). Ninety percent of the patients had grade 1-2 disease. Thirteen patients (21%) received intra vaginal brachytherapy (IVBT) and one received whole pelvic radiotherapy (WPRT). Median follow-up time was 46 months (range, 9-77 months). Three patients experienced recurrence (4.8%), two of them died on follow-up and one was still alive at last visit. Two patients with recurrence had FIGO grade 2 tumors and one had a grade 3 tumor. Two patients (3.2%) died without evidence of recurrent disease. Relapse free survival at 5 years was 94.4% and overall survival was 93.1%. Conclusions: Patients with stage IB disease in our study demonstrated relatively low recurrence rates although the majority of them received no adjuvant treatment. Surgery alone may be sufficient for most patients with this stage of endometrial cancer.

목적 : 근치적 절제술과 골반림프절 절제술을 시행한 자궁경부암 환자 중에서 치료실패의 위험인자가 있어서 술후 방사선치료를 시행한 환자를 대상으로 치료성적, 예후인자, 실패양상을 알아보기 위하여 후향적 분석을 시행하였다. 대상 및 방법 : FIGO 병기 IB, IIA와 IIB 환자 중에서 근치적 수술과 방사선치료를 시행하고 추적조사가 가능하였던 124명을 대상으로 하였다. 환자들은 1985년 3월부터 1994년 3원까지 수술후 방사선치료를 시행하였으며 최소 추적기간은 24개월이었다. 모든 환자는 4-MV 선형가속기를 이용한 외부방사선치료를 전골반에 50-6OGy를 조사하였고 일부 환자는 코발트를 이용한 고선량율 강내치료를 추가하였다. 결과 : 전체 환자의 5년 생존율과 5년 무병 생존율은 각각 $75.4\%,\;73.5\%$였고, 단변수 분석상 5년 무병 생존율에 영향을 미치는 인자는 림프절 전이 유무, 개수와 위치, 종양의 크기, 자궁체부 침운, 자궁주위조직 침윤, 병기, 자궁경부벽 침윤정도, 질 절제면 양성, 그리고 치료 관계 인자로 방사선량, 강내치료, 항암제 등이 통계상 유의하였으며, 다변량 분석상 림프절 전이와 종양의 크기, 질 절제면 양성이 유의하였다. 치료 실패는 33명이었고 2명은 다른 원인으로 사망하였고 부위별로는 국소재발이 13명, 원격전이 13명 국소-원격 동시 실패가 7명이었고 추적 종료시점까지 5명이 생존하였다. 국소재발은 병기 IB, 림프절 전이 양성 또는 질 절제면 양성 환자에서 많이 발생하였으며 림프절 전이 음성환자에서는 빈도는 낮았으나 원격전이가 상대적으로 더 많았다. 그리고 병기 lIB에서 5년 생존율 은 $56\%$ 였고 22명 중에서 9명이 재발하였다. 결론 : 수술후 방사선치료는 비교적 효과적인 방법이지만 다수의 재발 위험인자들을 가진 환자에게 술후 방사선치료만으로는 재발을 막기가 충분하지 않으므로 방사선감작제의 추가나 동시방사선-항암치료 등의 보다 효과적인 방법이 필요할 것으로 성각되며, 술혹 방사선치료의 효율을 정하기 위하여 무작위 표본 추출에 의한 전향적 연구가 필오하다. 그리고 병기 IIB는 항암치료와 수술후 방사선치료를 시행해도 치료 성적이 나쁘므로 일차적으로 근치적 방사선치료를 시행해야한다.

Purpose: To analyze prognostic factors for locoregional recurrence (LRR), distant metastasis (DM), and overall survival (OS) in cervical cancer patients who underwent radical hysterectomy followed by postoperative radiotherapy (PORT) in a single institute. Materials and Methods: Clinicopathologic data of 135 patients with clinical stage IA2 to IIA2 cervical cancer treated with PORT from 2001 to 2012 were reviewed, retrospectively. Postoperative parametrial resection margin (PRM) and vaginal resection margin (VRM) were investigated separately. The median treatment dosage of external beam radiotherapy (EBRT) to the whole pelvis was 50.4 Gy in 1.8 Gy/fraction. High-dose-rate vaginal brachytherapy after EBRT was given to patients with positive or close VRMs. Concurrent platinum-based chemoradiotherapy (CCRT) was administered to 73 patients with positive resection margin, lymph node (LN) metastasis, or direct extension of parametrium. Kaplan-Meier method and log-rank test were used for analyzing LRR, DM, and OS; Cox regression was applied to analyze prognostic factors. Results: The 5-year disease-free survival was 79% and 5-year OS was 91%. In univariate analysis, positive or close PRM, LN metastasis, direct extension of parametrium, lymphovascular invasion, histology of adenocarcinoma, and chemotherapy were related with more DM and poor OS. In multivariate analysis, PRM and LN metastasis remained independent prognostic factors for OS. Conclusion: PORT after radical hysterectomy in uterine cervical cancer showed excellent OS in this study. Positive or close PRM after radical hysterectomy in uterine cervical cancer correlates with poor prognosis even with CCRT. Therefore, additional treatments to improve local control such as radiation boosting need to be considered.
