목적 : 수술 및 수술 후 보조적 방사선치료를 시행한 자궁내막암 환자의 예후인자, 재발 장소 및 생존율 등을 분석해 보고자 하였다. 대상 및 방법: 1991년 9월부터 1997년 12월까지 서을중앙병원에서 수술 및 방사선치료를 받은 27예의 자궁내막암환자를 대상으로 하였다. 수술은 단순자궁적출술이 6예, 단순자궁적출술 및 림프절 절제술이 8예, 근치적 자궁적출 술이 13예에서 시행되었다. 모든 환자에서 외부 방사선치료가 시행되었으며 이 중 16예에서 ovoid를 이용한 질내조사가 추가되었다. 조사선량은 외부 방사선치료는 총 50.4 Gy를 조사하는 것을 원칙으로 하였고, 질내조사는 1회 분할선량 4$\~$5 Gy씩 4내지 5회 시행하였다. 추적기간은 6개월에서 95개월로서 중앙추적기간은 30개월이었다. 결과:FIGO 병기는 I-18예(67$\%$), II-1(4$\%$), III-8예(29$\%$)이었고, 조직분화도는 1$\~$14예(52$\%$), 2$\~$6예(9$\%$), 3$\~$7예(26$\%$)이었다. 수술 후 조직 소견상 조직분화도가 나쁠수록, 자궁근층의 침범 정도가 심할수록, 자궁부속기의 침범이있는 경우, 림프-혈관 침범이 있는 경우 골반내 림프절이 양성을 보이는 경우가 많았으나 통계적인 의미는 없었다. 추적이 종료된 시점에서 사망한 환자가 한 예도 없어 전체 생존율은 100$\%$이었으나 3예에서 병이 재발되어 3년 및 5년 무병생존율이 각각 89.6$\%$,, 76.8$\%$이었다. 재발 장소는 골반내, 대동맥방림프절, 폐를 포함한 다발성 등이 각각 I예 이었고 질 재발은 관찰되지 않았다. FIGO 병기(p=0.01), 림프-혈관 침범(p=0.03), 골반내 림프절 침범(p=0.0001)등이 무병생존을에 영향을 미치는 것으로 나타났고 조직분화도가 나쁠수록 무병생존율이 저조한 경향을 보였다(p=0.1). 치료부작용으로는 1예에서만 Grade 1의 직장출혈이 나타났으나 중등도 이상의 합병증을 보인 경우는 없었다. 결론 : 수술후 조직학적 소견에 따른 외부방사선치료 및 추가 질내조사는 국소재발을 억제하는데 효과적인 것으로 판단되며 결과적으로 생존율을 향상시키는데 기여하는 것으로 생각된다. 다만, 병기 및 조직분화도에 따라 질내조사를 추가하지 않는 경우 질 재발이 호발하는 환자군에 대한 연구가 더 진행되어야 할 것으로 판단된다.

Background: Evidence has accumulated that opioids can produce potent antinociceptive effects by interacting with opioid receptors in peripheral tissues. Bupivacaine has a potent analgesic effect with early peak onset in the postoperative period. The combination of intrapelvic bupivacaine and morphine has been suggested as an ideal analgesic after endoscopic pelvic surgery. Methods: Sixty patients scheduled for endoscopic pelvic surgery under general anesthesia were allocated randomly to three groups. Group 1 received normal saline 20 ml, group 2 received morphine 5 mg in normal saline 20 ml, and group 3 received morphine 5 mg in 0.25% bupivacaine 20 ml into the pelvic cavity. Postoperative pain was assessed using the visual analogue scale at 1, 2, 4, 8, and 24 hours after the intrapelvic instillation. Supplemental analgesic requirements, vital signs, and side effects were recorded for 24 hours. Results: Intrapelvic morphine and bupivacaine produced significant analgesia after endoscopic pelvic surgery. The patients in group 3 had lower pain scores than those in the group 1 and 2 at 1, 2 and 4th hours. There were no significant differences in the pain scores at 8 hours and 24 hours postoperatively between group 2 and 3. Supplemental analgesic requirements were significantly greater in the groups 1 and 2 than the group 3 for 24 hours. No significant side effects occurred. Conclusion: The intrapelvic instillation of morphine and bupivacaine is effective for the postoperative pain control in patients undergoing endoscopic pelvic surgery.

Neddylation is a post-translational protein modification process. MLN4924 is a newly discovered pharmaceutical neddylation inhibitor that suppresses cancer growth with several cancer types. In our study, we first investigated the effect of MLN4924 on colon cancer cells (HCT116 and HT29). MLN4924 significantly inhibited the neddylation of cullin-1 and colon cancer cell growth in a time and dose-dependent manner. MLN4924 induced G2/M cell cycle arrest and apoptosis in HCT116 and HT29 cells. Moreover, MLN4924 also triggered autophagy in HCT116 and HT29 cells via suppressing the PI3K/AKT/mTOR pathway. Inhibiting autophagy by autophagy inhibitor 3-MA or ATG5 knockdown reversed the function of MLN4924 in suppressing colon cancer cell growth and cell death. Interestingly, MLN4924 suppresses colon cell growth in a xenograft model. Together, our finding revealed that blocking neddylation is an attractive colon cancer therapy strategy, and autophagy might act as a novel anti-cancer mechanism for the treatment of colon cancer by MLN4924.

Background and Aim: Laparoscopic and open rectum surgery for rectal cancer remains controversial. This systematic review compared the short-term and long-term efficiency and complications associated with laparoscopic and open resection for rectal cancer. Materials and Methods: We searched PubMed, Embase, Cochrane Library, ISI Web of Knowledge and the China Biology Medicine Database to identify potential randomized controlled trials from their inception to March 31, 2014 without language restriction. Additional articles were identified from searching bibliographies of retrieved articles. Two reviewers independently assessed the full-text articles according to the pre-specified inclusion and exclusion criteria as well as the methodological quality of included trials. The meta-analysis was performed using RevMan 5.2. Results: A total of 16 randomized controlled trials involving 3,045 participants (laparoscopic group, 1,804 cases; open group, 1,241 cases) were reviewed. Laparoscopic surgery was associated with significantly lower intraoperative blood loss, earlier return of bowel movement and reduced length of hospital stay as compared to open surgery, although with increased operative time. It also showed an obvious advantage for minimizing late complications of adhesion-related bowel obstruction. Importantly, there were no significant differences in other postoperative complications, oncological clearance, 3-year and 5-year or 10 year recurrence and survival rates between two procedures. Conclusions: On the basis of this meta-analysis we conclude that laparoscopic surgery has advantages of earlier postoperative recovery, less blood loss and lower rates of adhesion-related bowel obstruction. In addition, oncological outcome is comparable after laparoscopic and open resection for rectal cancer.

Endometriosis is defined as the presence of functioning endometrial tissue outside the uterine cavity, and the standard treatment is extensive surgical excision. Cesarean scar endometriosis is a type of cutaneous endometriosis arising on or near a Cesarean section scar. A 44-year-old woman presented with a $9{\times}6$ cm sized dark-brown, stony-hard, irregular, lower abdominal mass of four years duration. The patient had a history of two Cesarean deliveries, 14 and 16 years ago. Suspecting endometriosis, we excised the tumor conservatively rather than extensively to prevent incisional hernia considering the benign nature of the tumor and the low possibility of recurrence because the patient's age was near menopause, along with simultaneous bilateral salpingo-oophorectomy that was performed in this case. On reconstruction, mini-abdominoplasty was adopted to avoid possible wound complications and cosmetic deformities. The patient was satisfied with the cosmetic results, and neither recurrence nor functional problems occurred during the 1-year follow-up period. Plastic surgeons should keep in mind the possibility of cutaneous endometriosis in an abdominal mass of a female of reproductive age with a previous history of pelvic or intra-abdominal surgery. An optimal result from oncological, functional, and cosmetic standpoints can be achieved with conservative excision followed by mini-abdominoplasty of extensive Cesarean scar endometriosis.

To date, there was no controlled-study regarding awareness and knowledge of colorectal cancer in the Turkish population. We therefore designed a questionnaire consisting of items related to socio-demographic parameters, medical and family history and questions of awareness and knowledge about colorectal cancer for use in a descriptive cross-sectional study. An interviewer-administered technique was applied and 450 subjects were interviewed in the outpatient clinics at Near East University Hospital. Among all subjects, 337 were found to be eligible for the study group. Exclusion criteria were age below 18 years, any cancer history, family history of colorectal cancer, current colorectal problems, history of any diagnostic or therapeutic interventions for colorectal diseases. All participants stated that they heard about colorectal cancer. When asked about the lifetime risk of colorectal carcinoma, only 25.4% of women and 37.9% of men estimated correctly. Univariate analysis revealed that the total awareness score was significantly correlated with age, marital status, parenthood and fecal occult blood testing history. On multivariate analysis of independent predictors for awareness of colorectal cancer were found to be history of fecal occult blood testing, age and marital status were found to be the most important determinants. As a conclusion, opportunistic screening with fecal occult blood test by physicians from non-gastrointestinal specialties not only helps to reduce the mortality but also increases the awareness of colorectal cancer.

Physician recommendation is an important predictor of HPV vaccine acceptance; however, physician willingness and preferences regarding HPV vaccination may be influenced by factors including patient age, vaccine type, and cost. A cross-sectional survey was administered to a convenience sample of health care providers in Da Nang, Vietnam, to evaluate awareness, perceptions about HPV and HPV vaccines, and willingness to vaccinate a female patient. Willingness to vaccinate was evaluated using a full-factorial presentation of scenarios featuring the following factors: vaccine cost (free vs 1,000,000 VND), patient age (12, 16, or 22 years), and HPV vaccine type (bivalent vs quadrivalent). Responses from 244 providers were analyzed; providers had a mean age of $34{\pm}11.9$ years; a majority were female, married, and had children of their own. Thirty-six percent specialized in obstetrics/gynecology and 24% were providers in family medicine. Of the three factors considered in conjoint analysis, vaccine cost was the most important factor in willingness to vaccinate, followed by patient age, and vaccine type. The most favorable scenario for vaccinating a female patient was when the vaccine was free, the patient was 22 years of age, and the HPV4 vaccine was described. In multivariable analysis, older age, being a physician, being married, and having children were all associated with increased willingness to recommend HPV vaccination (p<0.05). Provider willingness is an important aspect of successful HPV vaccination programs; identifying preferences and biases in recommendation patterns will highlight potential areas for education and intervention.

Purpose: To evaluate the outcomes of adjuvant radiotherapy (RT) and to analyze prognostic factors of survival in the International Federation of Gynecology and Obstetrics (FIGO) IB-IIA uterine cervical cancer. Materials and Methods: We retrospectively reviewed the medical records of 148 patients with FIGO IB-IIA uterine cervical cancer who underwent surgery followed by adjuvant RT at the Yonsei Cancer Center between June 1997 and December 2011. Adjuvant radiotherapy was delivered to the whole pelvis or an extended field with or without brachytherapy. Among all patients, 57 (38.5%) received adjuvant chemotherapy either concurrently or sequentially. To analyze prognostic factors, we assessed clinicopathologic variables and metabolic parameters measured on preoperative 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). To evaluate the predictive performance of metabolic parameters, receiver operating characteristic curve analysis was used. Overall survival (OS) and disease-free survival (DFS) were analyzed by the Kaplan-Meier method. Results: The median follow-up period was 63.2 months (range, 2.7 to 206.8 months). Locoregional recurrence alone occurred in 6 patients, while distant metastasis was present in 16 patients, including 2 patients with simultaneous regional failure. The 5-year and 10-year OSs were 87.0% and 85.4%, respectively. The 5-year and 10-year DFSs were 83.8% and 82.5%, respectively. In multivariate analysis, pathologic type and tumor size were shown to be significant prognostic factors associated with both DFS and OS. In subset analysis of 40 patients who underwent preoperative PET/CT, total lesion glycolysis was shown to be the most significant prognostic factor among the clinicopathologic variables and metabolic parameters for DFS. Conclusion: Our results demonstrated that adjuvant RT following hysterectomy effectively improves local control. From the subset analysis of preoperative PET/CT, we can consider that metabolic parameters may hold prognostic significance in early uterine cervical cancer patients. More effective systemic treatments might be needed to reduce distant metastasis in these patients.
