Background: To examine the incidence of positive vaginal surgical margins and determine the predicting factors following radical hysterectomy for stage IB1 carcinoma of the cervix. Materials and Methods: The clinical and histological data of 656 FIGO stage IB1 cervical cancer patients who had radical hysterectomy with bilateral pelvic lymphadenectomy (RHPL) from January 2003 to December 2012 were retrospectively reviewed and were analyzed for their association with a positive vaginal surgical margin. A p-value of < 0.05 was considered significant. Results: Thirty-five patients (5.3%) had positive vaginal surgical margins following RHPL; 24 (3.7%) for intraepithelial lesions and 11 (1.7%) for carcinoma. On multivariate analysis, microscopic vaginal involvement by high-grade squamous intraepithelial lesion and/or carcinoma (adjusted odd ratio (OR) 186.8; 95% confidence interval (CI) 48.5-718.5) and squamous histology (OR 8.7; 95% CI 1.7-44.0), were significantly associated with positive vaginal surgical margin. Conclusions: Microscopic vaginal involvement by HSIL and/or carcinoma are strong predictors for positive vaginal surgical margins for stage IB1 cervical cancer patients undergoing radical hysterectomy. Preoperative 'mapping' colposcopy or other strategies should be considered to ensure optimal vaginal resection.

Background: Cancer is one of the most common causes of death in Turkey. Nurses are essential providers of preventive care for patients, especially breast, cervical and colorectal cancer screening as part of routine preventive practice. The aim of this study was to assess knowledge of these cancers among nurses in Karabuk State Hospital. Materials and Methods: This cross-sectional and descriptive study was performed from April 1 to July 30, 2013. The study sample consisted of 226 nurses working in Karabuk State Hospital. Results: Mean age of the nurses was $32.07{\pm}8.39$. 62.4% of nurses practiced breast self examination when they remembered it, while 39.8% of them did not take a Pap smear test since they did not think it was necessary. 64.2% of nurses would like to receive information about cancer and screening tests. Majority of them had given true answers to questions on breast, cervical and colorectal cancer. There were significant relationships between cancer knowledge scores and marital status, working experience, and level of education. Conclusions: Nurses possess adequate knowledge about breast cancer but they need more information on cancer risk estimation. Awareness may be raised in nurses by establishing continuing education programs regarding the risk factors, symptoms, protection methods, early diagnosis, and scanning of breast, cervix and colon cancers.

Infection of the uterine cervix by human papilloma viruses (HPV) may be associated with cervical pre-cancer and invasive cervical carcinoma if left untreated. With advance in molecular techniques, it has become easier to detect the resence of HPV DNA long before the appearance of any lesion. This study concerned cervical scrape samples of 310 married non-pregnant women attending a gynecology outpatient department for both Pap and PCR testing to detect HPV DNA. Nested PCR using primers for L1 consensus gene with My9/My11 and GP6+/GP5+followed by multiplex PCR were carried out to detect HPV 16 and HPV18. Result: HPV prevalence was 11.9% out of which 3.67% cases of negative for intra-epithelial lesion or malignancy (NILM) and in 71.1% (27/38) of atypical cervical smears were HPV positive. There was increasing trend of high-risk-HPV positivity (HR HPV 16 and 18), from 20% in benign cytology (NILM) to 42.9 % in LSIL, 71.41% in HSIL and 100% in SCC. There was highly significant association of HPV infection with cervical lesion ($x^2=144.0$, p<0.01) and also with type specific HPV prevalence ($x^2=7.761^*$, p<0.05).

Along with a development of medical technology, a variety of tests, such as laboratory tests, x-ray and endoscopies are being used in health screening tests. As the tests determine the quality of health screening, test items and methods should be carefully selected. This study was to get hold of the test items of major health screening programs in Korea. Most of the health screening programmes focused upon detection of risk factors and diagnosis of life-style related diseases(diabetes, hypertension, cardiovascular diseases, hypercholesterolemia, overweight, drinking, smoking, cerebrovascular diseases, osteoporosis) ,cancers(stomach, cervix, lung, breast, liver, colon, prostate, ovary, pancreas, thyroid, esophagus), infectious diseases (hepatitis, tuberculosis, sexually-transmitted diseases, parasites),chronic obstructive respiratory diseases, chronic renal diseases(bacteriuria, hematuria, proteinuria), anemia, glaucoma, hearing loss, Alzheimer disease, stress, early Psychiatric diseases. The health screening tests were basic physical examination, basic laboratory tests(CBC, urinalysis, liver function tests, lipid tests, glucose, HbAlc, uric acid, electrolytes, serological tests(HBsAg, HBs-Ab, HCV-Ab, HIV-Ab, VDRL) EKG, x-ray(chest PA, CT), endoscopy (gastroscopy, colonoscopy) , sonography(abdormen, thyroid, pelvis, breast) , cytology(cervix) ,bone density, tumor markers(NMP22, alpha-FP, CEA, CA-19-9, CA12S, PSA) and eye tests. Advanced technologies, like CT, PET, MIRI, MIRI/Angio, molecular testings) were widely usedin hospital health screening programmes. In summary, a variety of were utilized by stages or programmes, however a few subjects. tests were utilized in health screening in Korea. Those tests according to sex and age in most of health screening program used tests to excess disregarding health screening subject.

Four pluriparous Korean black goat does were superovulated with FSH and mated with fertile bucks. Anesthetized animals were placed in lateral recumbency, then size 8 Foley catheter was inserted into the uterus through the cervix under the vaginal speculum and the balloon was inflated to fix the catheter in the uterine body. The opposite end of the catheter was connected to a 3-way and a flushing medium was infused into the uterus. Modified Dubecco's PBS with 1% FBS was used as the flushing medium. Four goats were allocated in two groups depending on the type of medium infusion into uterus. Injection group; the flushing medium was injected into uterus and the infused medium was collected by to-and-fro method using a syringe. Gravity-flow group; the flushing medium was allowed to enter the uterus by gravity flow by lifting the medium bottle and drained out of the uterus into a collecting tube. All four goats had catheter inserted through the cervix and uteri flushed successfully. The volume (recovery rate) of recovered medium varied considerably from 87 ml/200 ml (43.5%) to 148 ml/160 ml (92.5%). Nine embryos/ova in total were recovered from Gravity-flow group goats. Although the embryo recovery rate was low, the possibility of a transcervical embryo recovery in Korean black goat had been proven in this preliminary experiment.

Purpose: The role of radiotherapy in the management of patients with locoregional recurrent cervix cancer after radical surgery were retrospectively analyzed. Methods and materials: Twenty-eight patients treated with radiotherapy for locoregional recurrence after primary surgery for carcinoma of the cervix between 1989 and 1993 were analyzed. The median follow-up of survivors was 15 months (ranged 7-43 months). Eight patients had their disease confined to the vagina and 19 patients($68\%$) had pelvic mass as part of their locoregional recurrent disease. Within 24 months after the initial surgery, $82\%$ of recurrences manifested themselves. All patients had whole pelvic irradiation with or without intracavitary radiotherapy(ICR). Results: Complete response(CR) was achieved in 18 patients($54\%$). Five of eighteen patients($28\%$) with initial CR developed second locoregional recurrence. Response to radiotherapy correlated strongly with tumor volume, site of recurrence and total radiation dose. The overall 2 year survival rate was $43\%$ and the disease free survival was $31\%$. Survival rate was significantly influenced by the factors of interval from operation to recurrence, size and site of recurrent tumor, radiation dose, response of radiotherapy, lymph node status as initial presentation, The principal cause of death was lung metastasis($36\%$). Conclusion: Radiotherapy is an excellent modality for control of locoregional recurrent cervix cancer. To improve local control and survival rate, whole pelvic external radiotherapy in addition to ICR with more than 75.0Gy at the depth of 1.0cm from vaginal mucosa is needed and frequent follow up and early detection of recurrence is suggested as well.

Pupose: Radiation therapy(RT) is conventionally standard treatment for locally advanced stage for uterine cervix cancer. Recently to improve treatment results, combined chemotherapy and radiation therapy was tried We retrospectively analysed our experience of 122 patients. Comparision of the results in 45 patients treated with RT alone and 77 patients treated with RT plus chemotherapy was made Materials and Mathods: From January 1985 to December 1991 122 patients with cervix cancer were treated with whole pelvic external RT and ICR(34 1 ICR, 77 2 ICR, 11 high dose rate ICR) in our department. Forty five patients were treated with RT alone, and 77 patients were treated with combined RT plus chemotherapy Mean age was 58 years(range:29-81). Histologic types were 111 squamous cell carcinoma, 5 large cell carcinoma, 3 adenocarcinoma, and 2 adenosquamous cell carcinoma. According to the FIGO stage 6 had stage $IA(4.9\%),$ 11 had $IIA(9.0\%),$ 37 had $IIB(30.3\%),$ 3 had $IIIA(2.5\%),$ 63 had $IIIB(51.6\%).$ and 2 had stage $IV(1.6\%).$ In 77 patients with RT Plus chemotherapy, 36 patients were treated with VBP(vinblastin, bleomycin, cisplatinum) , 39 patients with cisplatinum plus 5-FU and 2 patients with 5-FU. Results: Complete response after external RT (3960cGy-5500cGy) was achieved in 61 patients$(50\%).$ The actuarial 5 year and 9 rear survival rate was $57.8\%\;and\;53.9\%,$ respectively. Five rear actuarial survival rate was $63.1\%$with RT alone(n=45) and $55.9\%$ with RT plus chemotherapy(n=77). The 5 rear survival rate was $35.5\%$ for 1 course of ICR and $67\%$ for 2 courses of ICR. There was statistically significant advantage of survival with RT alone group who were treated with 2 courses of ICR and dose to the A Point)=8000cGy (4/25 died). In RT plus chemotherapy group, dose response was not seen and there was no difference in 5 year survival between 1 course and 2 course of ICR $(50\%\;vs\;56.8\%),$ and dose to point A less than 8000 cGy and more than 8000 $cGy(55.6\%\;vs\;55.7\%).$ There was no significant difference in survival between RT alone and RT plus chemotherapy for patients with tumor size greater than 3cm in size. Five year survival rate for early stage (Stage IB and IIA) with RT alone group and with RT Plus chemotherapy group was $60\%\;and\;77.0\%,$ respectively In advanced stage (stage IIB, IIIA, IIIB, IVA) the 5 year actuarial survival rate were $62.6\%,$ for RT alone group vs $53.6\%$ for RT plus chemotherapy group. Conclusion: Present study demonstrates that there is no survival advantage with adding chemotherapy in advanced stage of uterine cervix cancer. RT alone is considered as treatment of choice for patients with locally advanced cervix cancer. There was increased survival in RT alone group treated with RT dose above 8000 cGy to point A and 2 course of ICR. but 2 course of ICR and RT dose above 8000 cGy to point A did not affect survival advantage in RT plus chemotherapy group.

Background: To examine the ultrasonographic and magnetic resonance (MRI) imaging findings of a cervical mass type cervical pregnancy. Materials and Methods: The ultrasonographic and MRI findings of 5 patients pathologically confirmed as having a cervical pregnancy were analyzed retrospectively. On ultrasonography, the size and echo pattern of the uterine cervix, the shape and echo pattern of the lesion, the degree and the pattern of blood flow on the color Doppler study and the spectral Doppler pattern were analyzed. The shape, signal intensity, and degree and pattern of enhancement of the lesion were evaluated on MRI. Results: The uterine cervix was enlarged and the size of the lesion was 6.1 to 7.1 (average, 6.5) cm. The endocervical canal was irregularly dilated and showed heterogeneous echogenicity in all 5 cases. Four of the 5 lesions were heterogeneously hyper- or mixed echoic and remaining one was relatively homogeneous echogenic. Doppler ultrasonography revealed an increased vascularity of the peritrophoblastic flow pattern. In all 4 cases where MRI performed, the lesion was irregular in shape and the margin was not sharply demarcated. The T2-weighed image showed that the lesions were mixed signal intensity. Three of the 4 lesions contained high signal intensity nodular portions and a low signal intensity rim was observed along the margin of the nodular portions. The T1-weighted image revealed multiple signal voids along the periphery of the lesions and high signal intensity portions as a result of hemorrhage were noted. The dynamic enhanced study showed that the high signal intensity portions on the T2-weighted image were strongly enhanced similar to the vessels on the early phase and the contrast enhancement gradually decreased with time. Conclusion: A cervical mass type cervical pregnancy can be correctly diagnosed using the patient's clinical symptom, the elevation in the serum ${\beta}$-HCG level, and characteristic ultrasonographic and MRI findings.

To identify pretreatment prognostic factors in locally advanced carcinoma of the uterine cervix, retrospective analysis was undertaken of 154 patients treated with curative radiation therapy at Seoul National University Hospital, from March 1979 through December 1986. According to FIGO classification, eight patients were stage IIIA, 134 were stage IIIB, and 12 were stage IVA. Five year locoregional control rate was $58\%$, $51\%$, and $27\%$ in stage IIIA, IIIB, and IVA, respectively. Five year disease free survival was $57\%$, $40\%$, and $25\%$ for each stage respectively. Five year overall survival was $67\%$, $51\%$, and $33\%$ in stage IIIA, IIIB, and IVA, respectively. In univariate analysis, fewer than or equal to four of pregnancies, initial hemoglobin of lower than $10\;g\%$, and pelvic sidewall invasion on CT were associated with poor locoregional control. Number of pregnancies, initial hemoglobin level, obstructive uropathy on intavenous pyelography (IVP), pelvic lymph node (LN) status on CT, and pelvic sidewall invasion on CT were significant factors in disease free survival. In terms of overall survival, pelvic sidewall invasion on CT and bladder invasion on CT were prognostically significant. In multivariate analysis, no factor was found to affect locoregional control and pelvic LN status was a sole significant factor affecting disease free survival. in terms of overall survival, the size.

The present research was carried out to evaluate the possibility of increasing female offspring production ratios using artificial insemination buffer (AIB) before artificial insemination (AI). In this experiment, we optimized AIB composition, made an AIB gun and analyze factors affecting AI non-return rate after AIB treatment. The AIB was made with the base of Tris-buffer supplemented with L-arginine and several other chemicals that might reduce the motility of male sperm compared to the female counterpart, therefore, increasing the possibility of fertilization by female sperm. AIB must be deposited into $2^{nd}$ to $4^{th}$ cervix by AIB gun. After 15 min of AIB deposition, frozen semen was deposited into the same place. A total of 348 cattle were inseminated with AIB insemination, and there were no significant differences between AIB and traditional AI non-return rates (56.8% vs. 55.7%). The AI non-return rate in AIB group, however, differed significantly among 7 Hanwoo farms. The parturition numbers ($1^{st}$ to $7^{th}$) of cows did not affect AIB AI rate. The proportion of AIB AI success rates was significantly higher in Hanwoo cows than in dairy cows (61.0% vs. 48.7%), but the average AI success rate did not differ significantly between AIB and conventional AI (56.8% vs. 55.7%). The female offspring production rate in $2^{nd}$ to $4^{th}$ cervix deposition place was significantly higher than that in the uterus body (77.7% vs. 59.6%, p<0.05). The injection volume of AIB in 5 and 10 ml was significantly higher than that in 2 ml (77.7%, 78.7% vs. 51.8%, p<0.05), but there were no differences in AIB injection volume between 5 and 10 ml. The best exposure time of AIB in the cervix was 10 to 15 min rather than 5 min (79.2%, 77.2% vs. 52.6%, p<0.05). AIB therefore needs to have an exposure time of at least over 10 min for a higher production rate of female offspring. In conclusion, AIB could be used in AI industry to increase the female offspring ratio and AIB AI can increase the AI success rate.
