Abstract
INTRODUCTION AND HYPOTHESIS The aim of this review is to provide a comprehensive overview of the current role of nerve-sparing radical hysterectomy (NSRH) in reducing the incidence of postoperative lower urinary tract dysfunction (LUTD) and in improving quality of life. METHODS A detailed online search was performed using the following keywords: nerve sparing, radical hysterectomy, cervical cancer, and all these terms in combination with urinary dysfunction or bladder dysfunction in order to analyze the effect of NSRH on urinary functional outcomes. Articles retrieved were analyzed and assigned a level of evidence (LE) according to the criteria of the Centre for Evidence-Based Medicine in Oxford, UK. RESULTS Our review highlights the heterogeneity of conducting and reporting studies in the literature. Autonomic pelvic nerve injuries during the procedure are thought to be the major cause of LUTD. The amount of LUTD depends upon the extent and type of nerve injury. Anatomically based surgical techniques are developed to avoid nerve injury without compromising oncological control. All studies comparing NSRH to standard RH yielded promising results with respect to postoperative LUTD. A recent meta-analysis showed similar cancer control rates between the two techniques. However, controversies remain about the ideal surgical approach for nerve sparing and there is no consensus as to the level and landmarks of dissection to preserve the maximal amount of nerves without compromising oncological outcomes. CONCLUSIONS Available evidence suggests that NSRH is safe and associated with lower incidence of LUTD. However, there is no standardized technique for NSRH and controversies remain about its oncological safety. Long-term oncological data from multicenter surgical trials are needed as well as a universally accepted standard to report studies on NSRH.

Abstract
To improve our understanding of cervical adenocarcinoma (AD) and evaluate the clinical and pathological variables affecting its prognosis, we retrospectively reviewed the medical records of 455 patients with cervical cancer [International Federation of Gynecology and Obstetrics stage I/II; 91 cases with AD and 364 with squamous cell carcinoma (SCC)] who underwent surgery at our hospital between January, 1995 and August, 2012 and compared the characteristics and prognoses between AD and SCC cases, including age, clinical stage, histological type, lymph node metastasis, lymphovascular space invasion (LVSI), cervical stromal invasion, parametrial invasion, vaginal invasion, corpus invasion, ovarian metastasis and tumor diameter. We used Cox regression analysis to determine independent prognostic factors. AD was found to have a significantly poorer prognosis in all the patients (P=0.001), stage I patients (P=0.001) and stage IB patients (P<0.05). The prognosis did not differ in patients who did not require postoperative treatment; however, patients who received postoperative treatment exhibited a significantly poorer prognosis (P<0.05). Patients with AD who received postoperative irradiation alone had a significantly poorer prognosis (P<0.05). The multivariate analysis identified LVSI (P=0.008), stromal invasion (P=0.024) and ovarian metastasis (P=0.032) as independent predictors of shorter survival. AD was associated with a worse prognosis compared to SCC in patients with stage IB disease, particularly in those who required postoperative treatment. Such patients may benefit from individualized postoperative treatments that differ from those applied for SCC.

Robot-assisted total preservation of the pelvic autonomic nerve with extended systematic lymphadenectomy as part of nerve-sparing radical hysterectomy for cervical cancer. Int J Gynecol Cancer 2014; 23:1133-8.

Abstract
OBJECTIVE To evaluate our short-term clinical outcomes of robot-assisted autonomic nerve-sparing extended systematic lymphadenectomy as part of nerve-sparing radical hysterectomy. METHODS Between March 2011 and June 2012, we observed prospectively 28 consecutive patients who underwent robot-assisted autonomic nerve-sparing extended systematic lymphadenectomy, including the superior and inferior gluteal, presacral (subaortic), common iliac, and lower para-aortic nodes. RESULTS The predominant International Federation of Gynecology and Obstetrics stage was IB1 (15 patients), followed by IB2 (5 patients), IA2 (3 patients), IIA1 (3 patients), and IIA2 (2 patients). The mean ± SD total operating time was 308.8 ± 54.9 minutes, and the mean ± SD console time was 280.0 ± 46.0 minutes. The mean ± SD blood loss was 102.7 ± 153.8 mL. The mean ± SD acquired pelvic lymph node was 27.1 ± 9.3, the mean ± SD extended lymph node was 19.2 ± 9.6, and the mean ± SD total lymph node was 46.3 ± 14.5. A total of 10 patients (35.7%) had nodal metastasis; among them, 6 patients (21.4%) had single pelvic nodal metastasis, 3 patients (10.7%) had concurrent pelvic and extended nodal metastasis, and one patient (3.6%) had single extended nodal metastasis. No intraoperative complications that required treatment occurred; however, ureterovaginal fistula was identified in 4 patients (14.3%) and ureter stricture in 4 patients (14.3%) after radiotherapy. After a median follow-up of 10 months (range, 1-16 months), there was no pelvic recurrence; however, one patient had recurrence at transposition site of ovary. CONCLUSIONS With the advantage of delicate movement of robot instrument, robot-assisted systematic extended lymphadenectomy with total preservation of pelvic autonomic nerves did not compromise the radicality, and its surgical technique was feasible and safe. By using this approach, we could harvest more lymph nodes and have a high rate of metastatic nodes without disturbing voiding function; however, there was increased rate of urological complications. Moreover, long-term survival benefit after an extended systematic lymphadenectomy must be evaluated.

Abstract
Objective The aim of this study was to investigate the prognostic factors and treatment outcome of patients with adenocarcinoma of the uterine cervix who underwent radical hysterectomy with systematic lymphadenectomy. Methods A total of 130 patients with stage IB to IIB cervical adenocarcinoma treated with hysterectomy and systematic lymphadenectomy from 1982 to 2005 were retrospectively analyzed. Clinicopathological data including age, stage, tumor size, the number of positive node sites, lymphovascular space invasion, parametrial invasion, deep stromal invasion (>2/3 thickness), corpus invasion, vaginal infiltration, and ovarian metastasis, adjuvant therapy, and survival were collected and Cox regression analysis was used to determine independent prognostic factors. Results An estimated five-year survival rate of stage IB1 was 96.6%, 75.0% in stage IB2, 100% in stage IIA, and 52.8% in stage IIB. Prognosis of patients with one positive-node site is similar to that of those with negative-node. Prognosis of patients with multiple positive-node sites was significantly poorer than that of negative and one positive-node site. Multivariate analysis revealed that lymph node metastasis, lymphovascular space invasion, and parametrial invasion were independent prognostic factors for cervical adenocarcinoma. Survival of patients with cervical adenocarcinoma was stratified into three groups by the combination of three independent prognostic factors. Conclusion Lymph node metastasis, lymphovascular space invasion, and parametrial invasion were shown to be independent prognostic factors for cervical adenocarcinoma treated with hysterectomy and systematic lymphadenectomy.

Abstract
BACKGROUND This is an updated version of the original Cochrane review published in The Cochrane Library, Issue 4, 2011.Cervical cancer is the most common cause of death from gynaecological cancers worldwide. Locally advanced cervical cancer, FIGO stage (International Federation of Gynaecology and Obstetrics) equal or more than IB1 is treated with chemotherapy and external beam radiotherapy followed by brachytherapy. If there is metastatic para-aortic nodal disease, radiotherapy is extended to cover this area. Due to increased morbidity, ideally extended-field radiotherapy is given only when para-aortic nodal disease is confirmed. Therefore, accurate assessment of the extent of the disease is very important for planning the most appropriate treatment. OBJECTIVES To evaluate the effectiveness and safety of pre-treatment surgical para-aortic lymph node assessment for woman with locally advanced cervical cancer (FIGO stage IB2 to IVA). SEARCH METHODS We searched the Cochrane Gynaecological Cancer Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2012, Issue 10), MEDLINE and EMBASE (up to November 2012). We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. SELECTION CRITERIA Randomised controlled trials (RCTs) that compared surgical para-aortic lymph node assessment and dissection with radiological staging techniques, in adult women diagnosed with locally advanced cervical cancer. DATA COLLECTION AND ANALYSIS Two review authors independently assessed whether potentially relevant trials met the inclusion criteria, abstracted data and assessed risk of bias. One RCT was identified so no meta-analyses were performed. MAIN RESULTS We found only one trial, which included 61 women, that met our inclusion criteria. This trial reported data on surgical versus clinical staging and an assessment of the two surgical staging techniques; laparoscopic (LAP) versus extraperitoneal (EXP) surgical staging. The clinical staging was either a contrast-enhanced computed tomography (CT) scan or magnetic resonance imaging (MRI) scan of the abdomen and pelvis to determine nodal status.In this trial, clinical staging appeared to significantly prolong overall and progression-free survival compared to surgical staging. There was no statistically significant difference in the number of women who experienced severe (grade 3 or 4) toxicity.There was no statistically significant difference in the risk of death, disease recurrence or progression, blood loss, severe toxicity and the duration of the operational procedure between LAP and EXP surgical staging techniques.The strength of the evidence is weak in this review as it is based on one small trial that was at moderate risk of bias. AUTHORS' CONCLUSIONS Since the last version of this review no new studies were found.From the one available RCT we found insufficient evidence that pre-treatment surgical para-aortic lymph node assessment for locally advanced cervical cancer is beneficial, and it may actually have an adverse effect on survival. However, this conclusion is based on analysis of a small single trial and therefore definitive guidance or recommendations for clinical practice cannot be made.Therefore, the decision to offer surgical pre-treatment assessment of para-aortic lymph nodes in locally advanced cervical cancer needs to be individualised. The uncertainty regarding any impact on survival from pre-treatment para-aortic lymph node assessment should be discussed openly with the women.

Abstract
Objectives With the objective of improving outcomes in oncological surgery, a new concept of surgical anatomy deduced from embryonic development, called ontogenetic anatomy and compartment theory of local tumor spread, is proposed by Michael Höckel from Germany. Hypothesis Compartment resection enables the preservation of functionally important tissues of different embryonic origin despite its close proximity to the tumor and incomplete resection of the compartment results in increase in local recurrences. This approach should maximize local tumor control and minimize treatment-related morbidity. Total Mesometrial Resection (TMMR) This new surgical technique has been developed and standardized over past 12 years for cervical cancer with a high local control rate without need for adjuvant radiotherapy. Conclusion This Embryological based surgery holds a great promise for management of cervical cancer. However this novel surgery needs confirmation in multi institutional settings to translate research into practice for an excellent therapeutic index.

Abstract
BACKGROUND Lower extremity lymphedema (LEL) is a serious complication caused by lymphadenectomy in patients with gynecologic malignancies. In this study, we evaluated the effect of preserving the circumflex iliac lymph nodes (CILNs), i.e., the most caudal external iliac lymph nodes, for the prevention and reduction of LEL by comparing two groups of patients, one in which CILN were removed and the other in which CILNs were preserved. METHODS We retrospectively reviewed 329 patients with gynecologic malignancies who had undergone abdominal complete systematic pelvic and para-aortic lymphadenectomy. The patients were divided into nonpreserved (n = 189) and preserved (n = 140) groups, depending on whether CILNs were removed. Primary outcome measures included the incidence and severity of LEL. RESULTS The incidence of LEL was significantly lower in the preserved group than in the nonpreserved group (P < 0.0001). The frequency of LEL was also significantly lower in the preserved group than in the nonpreserved group regardless of the range of pelvic and para-aortic lymphadenectomy (P < 0.0001). LEL in the overwhelming majority of cases in the preserved group was mild, and no patients experienced severe LEL. Further, the incidence of cellulitis was 0% in the preserved group, while it was 12.7% in the nonpreserved group (P < 0.0001). Lymphoscintigraphy revealed collateral pathways from the preserved CILN along the iliac and large abdominal vessels. CONCLUSIONS This method of lymph node preservation is a simple and extremely effective approach for preventing/reducing LEL after pelvic and para-aortic lymphadenectomy for patients with gynecologic malignancies.

Abstract
OBJECTIVE Lymph node metastasis (LNM) is known to be the most important prognostic factor in cervical cancer. We analyzed the number of positive lymph nodes and other clinicopathological factors as prognostic factors for survival in node-positive patients with cervical cancer. METHODS Node-positive cervical cancer patients (n = 108) who underwent radical hysterectomy and systematic lymphadenectomy in Hokkaido University Hospital from 1982 to 2002 were enrolled. Clinicopathological data including age, stage, histologic subtype, and the number of LNM sites were collected. The main outcome was the overall survival (OS) rate for Stage Ib-IIb patients treated with surgery and postoperative radiotherapy. RESULTS The 5-year OS rate of patients with 1 positive node was 93.3%, that for 2 nodes was 77.3%, for 3 nodes it was 33.3%, and for 4 or more it was 13.8%. The OS rate of patients with 1 or 2 LNM sites was significantly better than that for patients with more than 2 LNM sites. The OS rate of patients with adenocarcinoma (Ad) (28.6%) was significantly lower than that for patients with other histologic subtypes (squamous cell carcinoma; 66.7%, adenosquamous carcinoma; 75.0%, p = 0.0003). Multivariate analysis revealed that >2 LNM sites and Ad were independent prognostic factors for survival. The 5-year OS rate of patients with 1 or 2 LNM sites was 86.8%, a more favorable prognosis than the OS rates in other reports. CONCLUSION More than two LNM sites and adenocarcinoma were independent prognostic factors for node-positive patients with cervical cancer.

Abstract
Background: To determine the prognostic factors and treatment outcomes of patients with early-stage adenocarcinoma (AdCa) of uterine cervix who underwent radical hysterectomy (RH). Methods: Patients with early-stage squamous cell carcinoma (SCCa) of the uterine cervix who underwent RH were compared with patients with AdCa by multivariate analysis. Results: A total of 1218 patients were eligible, of which 996 (81.8%) had SCCa and 222 (18.2%) had AdCa. In multivariate analysis, parametrial involvement and lymph node metastasis were significant factors for both recurrence-free survival(RFS) and overall survival (OS) of patients with AdCa, whereas age, tumour size, parametrial involvement and lymph node metastasis were significant factors for both RFS and OS of patients with SCCa. After adjusting for significant prognostic factors, patients with AdCa had significantly poorer RFS (odds ratio (OR)=2.07, 95% confidence interval (CI)=1.37–3.12, P=0.001) and OS (OR=2.56, 95% CI=1.65–3.96, P<0.001) than patients with SCCa. Recurrence outside the pelvis was more frequent in AdCa than in those with SCCa (75 vs 57.8%, P=0.084). Conclusion(s): Although RH is still acceptable for treatment of patients with AdCa, a more effective systemic adjuvant therapy is required.

Abstract
OBJECTIVE To determine the prognostic factors in node-positive patients with early-stage cervical cancer who underwent radical hysterectomy (RH) and to use these factors to stratify patients into risk groups for individualized adjuvant therapy. METHODS Patients with early-stage cervical cancer who had lymph node metastasis after RH were retrospectively analyzed. RESULTS Multivariate analysis showed that non-squamous histology, tumor size and parametrial involvement were significantly associated with recurrence-free survival (RFS) and overall survival (OS). Prognostic scores were generated for these factors, and patients were categorized into low- (score 0; n=74), intermediate- (score 1-2; n=100) and high- (score 3-4; n=14) risk groups. Relative to the low-risk group, the probability of cancer recurrence was significantly higher in the high- (OR=10.87, 95% CI=4.22-28.0, P<.001) and intermediate- (OR=3.01, 95% CI=1.37-6.58, P=.006) risk groups. Moreover, the probability of cancer death was significantly higher in the high- (OR=9.88, 95% CI=3.76-25.94, P<.001) and intermediate- (OR=2.49, 95% CI=1.12-5.55, P=.026) risk groups compared with the low-risk group. The rates of pelvic failure and distant recurrence increased with increasing risk. CONCLUSION(S) Node-positive patients were heterogeneous, with different prognoses and recurrence patterns according to clinicopathologic risk factors. Further clinical trials are warranted to develop adjuvant treatment strategies individualized to each risk group.

Abstract
OBJECTIVE To review the modified (type II) radical hysterectomy procedures performed by 4 general gynecologists at the University Hospital of the West Indies, and to compare the outcomes with those of other published studies. METHODS The case notes of the 58 women who underwent radical hysterectomies between January 1997 and December 2006 were reviewed. Accuracy of staging, duration of the operation, operative blood loss, types and rates of complications, recurrence rates, and 5-year survival rates were assessed. RESULTS Accuracy of clinical staging, duration of the procedure, blood loss, and operative and postoperative complications were comparable to previously published data. The 5-year survival rate of 77.6% was also comparable to results seen in some other publications. CONCLUSION General gynecologists with significant experience in general gynecologic surgery who underwent adequate, but abbreviated, training became competent in performing a radical hysterectomy, with outcomes comparable to those seen in high-resource countries.

Abstract
Lymph node status is not part of the staging system for cervical cancer, but provides important information for prognosis and treatment. This article reviews the incidence and patterns of lymph node metastasis, and the issues surrounding surgical assessment of lymph nodes. The preoperative assessment of lymph nodes by imaging, as well as the intraoperative assessment by sentinel nodes will be discussed. Finally, the prognostic and therapeutic implications of lymphadenectomy in cervical cancer will be reviewed.

Abstract
Lymph node metastasis (LNM), together with parametrial infiltration and positive surgical margins, is an important prognostic factor in cervical cancer. The incidence of LNM increases with International Federation of Gynecology and Obstetrics (FIGO) stage, with rates being 12%-22% in stage Ib, 10%-27% in stage IIa, and 34%-43% in stage IIb. Radical hysterectomy and pelvic lymphadenectomy are widely used treatments for early-stage (Ib to IIa) cervical cancer, as well as for stage IIb disease, in some European and Asian countries. In several types of cancer, the therapeutic significance of systematic lymphadenectomy has been demonstrated by recent reports showing that a larger number of lymph nodes removed relates to better survival. In cervical cancer, a significant relationship between the number of lymph nodes removed and disease-free survival has been reported in node-positive patients. Preoperative evaluation of nodal status with computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET) imaging techniques is not sensitive enough to replace the histological examination of dissected nodes. The sentinel node procedure may be an alternative to systematic lymphadenectomy to reduce treatment-related morbidity, but more work on this is needed. Although the presence of LNM does not change FIGO staging, it will modulate postoperative therapy. Progression-free and overall survivals were significantly improved by the addition of chemotherapy to adjuvant radiotherapy after radical hysterectomy and lymphadenectomy. Adjuvant chemotherapy combined solely with radical hysterectomy and systematic lymphadenectomy may also provide a survival benefit. In conclusion, efforts to establish more tailored surgical strategies, by introducing advanced imaging technologies and molecular diagnostic procedures, are needed for cervical cancer.

Abstract
AIM To evaluate the distribution pattern of lymph node metastasis and to determine the optimal extent of pelvic lymphadenectomy (LA) in FIGO stage IB cervical cancer. METHODS The medical records of 187 patients with FIGO stage IB cervical cancer from March 1996 to December 2002 were reviewed retrospectively. The distribution pattern and risk factors of lymph node metastases were analyzed in 31 patients with lymph node metastases confirmed surgically. One hundred patients, who underwent type III hysterectomy with pelvic LA but did not receive any adjuvant treatment, were analyzed to evaluate whether the extent of LA affected the prognosis of FIGO stage IB cervical cancer. Type I LA included the external iliac nodes, hypogastric nodes, obturator nodes, and parametrial nodes. Type II LA included the pelvic nodes described in type I LA, the common iliac nodes, gluteal nodes, deep inguinal nodes and sometimes the presacral nodes. RESULTS Solitary lymph node metastasis confined to one node group was seen in the obturator, external iliac or hypogastric lymph nodes. All patients with lymph node metastases at multiple sites had metastasis in at least one of these lymph-node groups. There was no significant difference in disease-free survival and overall survival in patients without pathologic high-risk factors according to the type of pelvic LA. CONCLUSION The extent of LA should be adjusted to reduce complications and not to affect adversely the prognosis of FIGO stage IB cervical cancer patients without pathologic high-risk factors.

Abstract
AIM The aim of this study was evaluation of the efficacy of neoadjuvant chemotherapy (NACT) and radical hysterectomy on long-term survival in stage IB-IIA locally advanced cervical cancer as compared with radical surgery alone. METHODS We reviewed all patients with cervical cancer stage IB-IIA who were treated with two treatment modalities, i.e. NACT followed by radical hysterectomy and lymphadenectomy, and radical hysterectomy alone between March 1996 and March 2004. There were 22 patients in the NACT group (group 1) and 160 patients in the immediate radical surgery group (group 2). All patients in group 1 were followed for more than 108months, and long-term survival and factors affecting recurrence were evaluated. RESULTS Nineteen patients in the NACT arm underwent radical surgery. Pelvic lymph node metastasis was found in 8 patients in this group and in 36 in the radical surgery group. Eighteen patients in the NACT group and 96 patients in the radical surgery group were scheduled for adjuvant postoperative chemoradiation. During the 9-year follow-up, recurrence rate was 47.1% and 30.2% in NACT and control groups, respectively. In the NACT group lymph node metastasis was a significant independent risk factor for recurrence. Overall survival in the NACT arm was not statistically significantly lower than the control arm (p=0.06). CONCLUSION NACT did not improve long-term overall survival of bulky early-stage cervical cancer patients compared to primary radical surgery.

Abstract
OBJECTIVE To analyse the fertility rates, complications and recurrences in a group of women who have undergone radical vaginal trachelectomy and pelvic lymphadenectomy for early-stage cervical cancer. DESIGN An observational series. SETTING A Gynaecological Oncology Centre. POPULATION One hundred and twenty-three consecutive women who underwent radical vaginal trachelectomy and pelvic lymphadenectomy for early-stage cervical cancer. METHODS Data were collected prospectively. MAIN OUTCOME MEASURES Complications, recurrences, pregnancies and live births are presented as percentages of the total population. Fertility is presented as a 5-year cumulative rate, with women attempting to conceive as the denominator. RESULTS A total of 123 women were followed up for an average of 45 months. Eleven (8.9%) had completion treatment (two radical hysterectomies and nine chemoradiotherapy) at the time of initial treatment. There were three recurrences (2.7%) among the women who did not have completion treatment and two (18.2%) in those who did. There were 6 perioperative and 26 postoperative complications. Sixty-three women attempted pregnancy. There were 55 pregnancies in 26 women and 28 live births in 19. Three women had continuing pregnancies. The 5-year cumulative pregnancy rate among women trying to conceive was 52.8%. All but two women were delivered by classical caesarean section and seven (25.0%) babies were born at 31+6 weeks or less. CONCLUSIONS For selected women with early-stage cervical cancer, radical vaginal trachelectomy and pelvic lymphadenectomy are fertility-sparing options, with a low incidence of recurrence and acceptable cumulative conception rates. Complications are few, although there is a high premature labour and miscarriage rate among pregnant women.

Abstract
The objective of this study was to assess the role of postoperative radiotherapy (RT) in early-stage cervical carcinoma with risk factors other than positive nodes, parametrial invasion, or positive margins and to compare outcomes using the Leiden University Medical Center (LUMC) modification of the Gynecologic Oncology Group (GOG) system with the GOG prognostic scoring system itself. Between January 1984 and April 2005, 402 patients with early-stage cervical cancer underwent radical hysterectomy. A total of 51 patients (13%) had two of the three risk factors and had pathologic tumor size (> or =40 mm), invasion (> or =15 mm), and capillary lymphatic space involvement, and were identified as the so-called high-risk (HR). We compared 34 patients who received RT based on the LUMC risk profile (67%) with 17 who did not (33%). The GOG score was calculated as well. We compared the GOG scores within the LUMC risk groups: HR+ (two out of three risk factors) and HR- (less than two out of three risk factors). Differences in 5-year cancer-specific survival (CSS) and 5-year disease-free survival (DFS) between the HR group treated with RT (86%, 85%) and without RT (57%; 43%) were statistically significant. The LUMC criteria did not significantly differ from the GOG risk profile, concerning recurrence, CSS, and DFS. HR patients benefit from adjuvant RT. The LUMC modification of the GOG system seems to be simpler and has a slightly higher threshold for the indication for RT but without a difference in outcome.

Abstract
OBJECTIVES To evaluate the association between bcl-2 expression, some pathological factors (lymph-vascular space invasion (LVSI), tumor grade, depth of stromal invasion), and tumor recurrence in cervical cancer. METHODS A matched case-control study was performed in cervical cancer patients who underwent radical hysterectomy and were found to have negative lymph node between January 1992 and June 1998 in Bangkok Metropolitan Administration Medical College and Vajira Hospital and Maharaj Nakorn Chiangmai Hospital, Thailand. Cases were 32 patients who had tumor recurrence within 5 years after surgery. Controls were 63 patients who were disease free for at least 5 years after surgery. Cases and controls were matched for age, stage, histology, and tumor size. All except one case, who had only one matching control, had two controls. Paraffin-embedded cervical cancer tissues of cases and controls were immunohistochemical stained for bcl-2. RESULTS Bcl-2 positive was demonstrated in 43.7% of tumor from recurrent cases, which was not different from 50.8% from non-recurrent controls (P = 0.378). Tumor grade and LVSI had significant association with tumor recurrence. From multivariable analysis, the patients with grade 2-3 tumors had the odds ratio of 6.9 for recurrence compared to patients with grade 1 tumors. The patients whose tumors had LVSI had the recurrent odds ratio of 5.4 compared to those without LVSI. CONCLUSIONS There was no association between bcl-2 expression and tumor recurrence in cervical cancer, while tumor grade and LVSI had significant association with tumor recurrence.

Abstract
BACKGROUND Brachytherapy (BT) is an integral part of cervical carcinoma treatment. There have been no attempts to estimate the optimal proportion of new cervical carcinoma cases that should be treated with BT, that is, the optimal rate of brachytherapy utilization (BTU). METHODS Evidence-based guidelines and primary evidence were used to construct a BTU tree for carcinoma of the uterine cervix. Searches were performed of the epidemiological literature to ascertain the proportion of patients who fulfilled criteria for BT. The robustness of the model was tested by sensitivity analyses and by peer review. A patterns of care study of BT in New South Wales for 2003 was conducted, and actual BTU for cervical carcinoma determined. The differences between optimal and actual rates of BTU were assessed. RESULTS The optimal cervical carcinoma BTU was 49% (range, 42% to 50%). In New South Wales in 2003, actual BTU was only 30% of 256 cervical carcinoma patients. The major discrepancy was for FIGO stage IB-IIA disease, where there was an underutilization of BT, estimated to be 15% actual use compared with 47% optimal use. In Surveillance, Epidemiology, and End Results (SEER) areas, there was underutilization for stage IB-IIA (22% actual BTU versus 47% optimal BTU) and for stage IIB-IVA (54% actual BTU versus 100% optimal BTU). CONCLUSIONS BT for cervical carcinoma is underutilized in New South Wales and in SEER areas. The authors' model of optimal BTU can be used as a quality assurance tool to provide an evidence-based benchmark against which actual patterns of practice can be measured. The model can also be used to help determine adequacy of BT resource allocation.

Abstract
The aim of this study was to determine whether the pelvic lymph nodes would predict the parametrial status in patients with cervical cancer stages IB1-IIA submitted to radical surgery and pelvic lymphadenectomy. To this end, we evaluated the relationship between positive and negative pelvic lymph nodes and their parametria. Our final purpose was to use this information to recommend the tailoring of the parametrial resection according to the status of pelvic lymph nodes to decrease the morbidity related with radical paratrectomy. From January 1996 to December 2001, 107 consecutive patients with cervical cancer stages IB1 and IIA were primarily treated by radical hysterectomy type III with systematic pelvic lymphadenectomy in a prospective study. Parametria were studied in two sections: the first included the tissue adjacent to the cervix, and the second the distal 2/3. Lymph nodes were routinary processed. Twenty-two patients (20.6%) had positive pelvic nodes and 16 patients (14.9%) had parametrial involvement, mostly by direct extension. Eight patients with positive pelvic nodes (36.4%) had parametrial involvement, whereas among 85 patients with negative pelvic nodes only eight patients (9.4%) had parametrial involvement (P < 0.001), most in internal parametria (62.5%). The sensitivity of pelvic lymph nodes for parametrial involvement was 50% and the positive predictive value was 36.4%, whereas the specificity was 84.6%; and the negative predictive value 90.6%. In the group of negative pelvic lymph nodes, only two patients (2.3%) had parametrial involvement beyond internal parametria. The univariated and multivariated analysis of prognostic factors was always significant but without a significant independent factor for positive parametria. Pelvic lymph nodes appear as good predictors of parametrial status, especially in node-negative patients, and could be used to decrease the paratrectomy in radical surgery.

Abstract
BACKGROUND Radiotherapy usage rates exhibit wide variations both within and between countries. Current estimates of the proportion of cancer patients who should optimally receive radiotherapy are based either on expert opinion or on the measurement of actual usage rates rather than on the best available scientific evidence. METHODS With the goal of developing an evidence-based benchmark for radiotherapy use in the treatment of malignancies of the cervix, vagina, vulva, and ovary (endometrial malignancies are covered in a separate article), the authors reviewed international evidence-based treatment guidelines. Optimal radiotherapy usage trees were constructed, and proportions of patients with clinical indications for radiotherapy were obtained from epidemiologic data. These ideal usage rates were compared with actual radiotherapy utilization rates recorded in Australia and elsewhere. RESULTS According to the best available evidence, radiotherapy is indicated at least once for 58% of patients with cervical carcinoma, 4% of patients with ovarian carcinoma, 100% of patients with vaginal carcinoma, and 34% of patients with vulvar carcinoma. A review of the limited data available suggests that actual radiotherapy usage rates for patients with gynecologic malignancies are comparable to optimal usage rates. CONCLUSIONS Actual practice appears to approximate the authors' model of optimal radiotherapy use. This finding reflects the high level of agreement among treatment guidelines as well as the existence of high-quality evidence related to the management of gynecologic malignancies, and it may also be indicative of the fact that a large proportion of patients are treated in specialist units. The management of gynecologic malignancies may serve as a good example in the development of management strategies for other types of cancer.

Abstract
OBJECTIVE To determine whether lymph vascular space involvement (LVSI) in women with early cervical carcinoma is an independent prognostic factor. METHODS The literature was reviewed using Medline and known literature to determine if LVSI is an independent risk factor as determined by multivariant analysis with survival being the end point in patients undergoing radical hysterectomy and pelvic lymphadenopathy. RESULTS A total of 25 articles were identified that satisfied the evaluation criteria. Only three (12%) identified LVSI as an independent risk factor while 88% and 61% of those evaluated, noted lymph node metastasis and tumor size/depth of invasion to be significant risk factors for survival. CONCLUSIONS Using LVSI as the sole determining factor for consideration of post radical hysterectomy radiotherapy appears questionable.

Abstract
Radical hysterectomies for the treatment of cervical carcinoma are being performed laparoscopically by some surgeons. Others combine the laparoscopic lymphadenectomy with a radical vaginal hysterectomy or a radical trachelectomy, like in the Schauta procedure. In this way the procedure resembles the AVRUEL-procedure (Abdominal Vaginal Radical Uterus Extirpation with transperitoneal Lymphadenectomy), as developed in 1957 by Sindram who combined the Wertheim and the Schauta procedure together with abdominal lymphadenectomy in one single operation. Because of the high complication rate in the form of voiding problems and sexual impairment caused by the Schauta part, this operation is no longer performed. In order to pay attention to the morbidity associated in the past with the combined abdomino-vaginal approach compared to the single abdominal approach, we reassembled the data of several large Dutch centers where patients were treated either by the AVRUEL or the abdominal radical hysterectomy. A total of 730 patients underwent an AVRUEL procedure, all carried out between 1957 and 1981. Fistulas occurred in 57 patients (7.8%), long-term urologic complications in 233 patients (32%), and sexual dysfunction in 71 (9.7%) were found. A total of 928 patients underwent an abdominal radical hysterectomy, of whom in 511 cases the complication rates have been described. Twelve fistulas occurred (2%), long-term micturition problems in 55 (10%), and sexual problems in 11 (2%). There was no difference in 5-year survival rates in both groups. From the above-mentioned data it is clear, that returning to the old days in terms of a re-introduction of the Schauta procedure is not to be preferred. In order to conclude if the laparoscopically assisted radical vaginal hysterectomy or the trachelectomy are an improvement, they should be carried out according to clearly defined prospective protocols in which data can be compared to those of other techniques with special attention to late complications including micturition and sexual sequelae.
