Objective To evaluate disease-free survival of cervical conization prior to radical hysterectomy in patients with stage IB1 cervical cancer (International Federation of Gynecology and Obstetrics (FIGO) 2009). Methods A multicenter retrospective observational cohort study was conducted including patients from the Surgery in Cervical Cancer Comparing Different Surgical Aproaches in Stage IB1 Cervical Cancer (SUCCOR) database with FIGO 2009 IB1 cervical carcinoma treated with radical hysterectomy between January 1, 2013, and December 31, 2014. We used propensity score matching to minimize the potential allocation biases arising from the retrospective design. Patients who underwent conization but were similar for other measured characteristics were matched 1:1 to patients from the non-cone group using a caliper width <= 0.2 standard deviations of the logit odds of the estimated propensity score. Results We obtained a weighted cohort of 374 patients (187 patients with prior conization and 187 non-conization patients). We found a 65% reduction in the risk of relapse for patients who had cervical conization prior to radical hysterectomy (hazard ratio (HR) 0.35, 95% confidence interval (CI) 0.16 to 0.75, p=0.007) and a 75% reduction in the risk of death for the same sample (HR 0.25, 95% CI 0.07 to 0.90, p=0.033). In addition, patients who underwent minimally invasive surgery without prior conization had a 5.63 times higher chance of relapse compared with those who had an open approach and previous conization (HR 5.63, 95% CI 1.64 to 19.3, p=0.006). Patients who underwent minimally invasive surgery with prior conization and those who underwent open surgery without prior conization showed no differences in relapse rates compared with those who underwent open surgery with prior cone biopsy (reference) (HR 1.94, 95% CI 0.49 to 7.76, p=0.349 and HR 2.94, 95% CI 0.80 to 10.86, p=0.106 respectively). Conclusions In this retrospective study, patients undergoing cervical conization before radical hysterectomy had a significantly lower risk of relapse and death.

Objective Based on the SUCCOR study database, our primary objective was to identify the independent clinical pathological variables associated with the risk of relapse in patients with stage IB1 cervical cancer who underwent a radical hysterectomy. Our secondary goal was to design and validate a risk predictive index (RPI) for classifying patients depending on the risk of recurrence. Methods Overall, 1116 women were included from January 2013 to December 2014. We randomly divided our sample into two cohorts: discovery and validation cohorts. The test group was used to identify the independent variables associated with relapse, and with these variables, we designed our RPI. The index was applied to calculate a relapse risk score for each participant in the validation group. Results A previous cone biopsy was the most significant independent variable that lowered the rate of relapse (odds ratio [OR] 0.31, 95% confidence interval [CI] 0.17-0.60). Additionally, patients with a tumor diameter >2 cm on preoperative imaging assessment (OR 2.15, 95% CI 1.33-3.5) and operated by the minimally invasive approach (OR 1.61, 95% CI 1.00-2.57) were more likely to have a recurrence. Based on these findings, patients in the validation cohort were classified according to the RPI of low, medium, or high risk of relapse, with rates of 3.4%, 9.8%, and 21.3% observed in each group, respectively. With a median follow-up of 58 months, the 5-year disease-free survival rates were 97.2% for the low-risk group, 88.0% for the medium-risk group, and 80.5% for the high-risk group (p < 0.001). Conclusion Previous conization to radical hysterectomy was the most powerful protective variable of relapse. Our risk predictor index was validated to identify patients at risk of recurrence.

Background Pelvic recurrences from previously irradiated gynecological cancer lack solid evidence for recommendation on salvage. Methods A total of 58 patients were included in this clinical analysis. Salvage surgery was performed for locoregional relapse within previously irradiated pelvic area after initial surgery and adjuvant radiotherapy or radical external beam radiotherapy. The primary tumor diagnosis included cervical cancer (n = 47, 81%), uterine cancer (n = 4, 7%), and other types (n = 7, 12%). Thirty-three patients received adjuvant IOERT (1984-2000) at a median dose of 15 Gy (range 10-20 Gy) and 25 patients received adjuvant PHDRB (2001-2016) at a median dose of 32 Gy (range 24-40 Gy) in 6, 8, or 10 b.i.d. fractions. Results The median follow-up was 5.6 years (range 0.5-14.2 years). Twenty-nine (50.0%) patients had positive surgical margins. Grade >= 3 toxic events were recorded in 34 (58.6%) patients. The local control rate at 2 years was 51% and remained stable up to 14 years. Disease-free survival rates at 2, 5, and 10 years were 17.2, 15.5, and 15.5%, respectively. Overall survival rates at 2, 5, and 10 years were 58.1, 17.8, and 17.8%, respectively. Conclusions IOERT and PHDRB account for an effective salvage in oligorecurrent gynecological tumors. Patients with previous pelvic radiation suitable for salvage surgery and at risk of inadequate margins could benefit from adjuvant reirradiation in form of IOERT or PHDRB. However, the rate of severe grade >= 3 toxicity associated with the entire treatment program is relevant and needs to be closely counterbalanced against the expected therapeutic gain.

Introduction Comprehensive updated information on cervical cancer surgical treatment in Europe is scarce. Objective To evaluate baseline characteristics of women with early cervical cancer and to analyze the outcomes of the ESGO quality indicators after radical hysterectomy in the SUCCOR database. Methods The SUCCOR database consisted of 1272 patients who underwent radical hysterectomy for stage IB1 cervical cancer (FIGO 2009) between January 2013 and December 2014. After exclusion criteria, the final sample included 1156 patients. This study first described the clinical, surgical, pathological, and follow-up variables of this population and then analyzed the outcomes (disease-free survival and overall survival) after radical hysterectomy. Surgical-related ESGO quality indicators were assessed and the accomplishment of the stated recommendations was verified. Results The mean age of the patients was 47.1 years (SD 10.8), with a mean body mass index of 25.4 kg/m(2) (SD 4.9). A total of 423 (36.6%) patients had a previous cone biopsy. Tumor size (clinical examination) <2 cm was observed in 667 (57.7%) patients. The most frequent histology type was squamous carcinoma (794 (68.7%) patients), and positive lymph nodes were found in 143 (12.4%) patients. A total of 633 (54.8%) patients were operated by open abdominal surgery. Intra-operative complications occurred in 108 (9.3%) patients, and post-operative complications during the first month occurred in 249 (21.5%) patients, with bladder dysfunction as the most frequent event (119 (10.3%) patients). Clavien-Dindo grade III or higher complication occurred in 56 (4.8%) patients. A total of 510 (44.1%) patients received adjuvant therapy. After a median follow-up of 58 months (range 0-84), the 5-year disease-free survival was 88.3%, and the overall survival was 94.9%. In our population, 10 of the 11 surgical-related quality indicators currently recommended by ESGO were fully fulfilled 5 years before its implementation. Conclusions In this European cohort, the rate of adjuvant therapy after radical hysterectomy is higher than for most similar patients reported in the literature. The majority of centers were already following the European recommendations even 5 years prior to the ESGO quality indicator implementations.

Background Adoptive immunotherapy with tumour-infiltrating lymphocytes (TIL) may benefit from the use of selective markers, such as PD-1, for tumour-specific T-cell enrichment, and the identification of predictive factors that help identify those patients capable of rendering tumour-reactive TILs. We have investigated this in ovarian cancer (OC) patients as candidates for TIL therapy implementation. Methods PD-1(-) and PD-1(+) CD8 TILs were isolated from ovarian tumours and expanded cells were tested against autologous tumour cells. Baseline tumour samples were examined using flow cytometry, multiplexed immunofluorescence and Nanostring technology, for gene expression analyses, as well as a next-generation sequencing gene panel, for tumour mutational burden (TMB) calculation. Results Tumour-reactive TILs were detected in half of patients and were exclusively present in cells derived from the PD-1(+) fraction. Importantly, a high TIL density in the fresh tumour, the presence of CD137(+) cells within the PD-1(+)CD8(+) TIL subset and their location in the tumour epithelium, together with a baseline T-cell-inflamed genetic signature and/or a high TMB, are features that identify patients rendering tumour-reactive TIL products. Conclusion We have demonstrated that PD-1 identifies ovarian tumour-specific CD8 TILs and has uncovered predictive factors that identify OC patients who are likely to render tumour-specific cells from PD-1(+) TILs.

Introduction: We aimed to analyze the outcome in a series of women with primary advanced ovarian cancer in an Intermediate Volume Hospital where new surgical and chemotherapy treatments were implemented over a period of 14 years. Material and Methods: One hundred and twenty-seven women with stage IIIB-IV disease underwent primary (76.4%) or interval debulking surgery (23.6%). Fifty-seven were operated on from 2000 to 2005 (Group 1) and 70 from 2006 to 2014 (Group 2). Results: No gross residual disease was achieved in 51.5% and 43.3% of women who underwent primary and interval surgery, respectively. For no gross and < 1cm residual disease, median overall and progression-free survival were 94.7 vs. 60.6 months (p = 0.001) and 25.3 vs. 20.0 months, respectively (p = 0.02). The rate of no gross residual (36.8 to 60.0%) and 5-yr median overall survival (56.3 to 73.7 months) increased between 2000-2005 (Group 1) and from 2006 to 2014 (Group 2). On multivariate analysis, interval surgery, multiple peritoneal implants and residual disease were predictive of overall and progression-free survival. Conclusions: Survival after primary and interval debulking surgery progressively correlates with decrease in residual disease. Increasing rates of successful primary surgery are possible through standardization and adoption of best practices without increasing morbidity.

Objective: "En-bloc" resection of pelvic tumor in ovarian cancer (OC) is still controversial. The aim was to analyze results in an OC series from a single center, all of whom underwent "en-bloc" resection as part of cytoreductive surgery. Material and Methods: Clinical and surgical records from sixty patients with ovarian carcinoma who underwent "en-bloc" resection surgery were retrospectively analyzed. Results: Patients' mean age was 56 years; 36 patients had primary disease and 24 had recurrent disease. Carcinomatosis was present in 46.7% of patients. Primary surgery was performed in 49 and interval debulking surgery in eleven. Complete cytoreduction was achieved in 55.0% and optimal in 38.3% of patients. Carcinomatosis significantly decreased the probability of complete cytoreduction [odds ratio (OR): 0.22; p=0.021]. Mesorectal infiltration occurred in 83% of patients. Risk of death was non-significantly higher (hazard ratio: 1.9) in women with mesorectal infiltration. Median overall survival was longer for patients without infiltration (46.1 vs 79.1 months; p=0.15). Eighty-five percent suffered from mild to moderate complications and colorectal anastomosis (CRA) leak occurred in two patients (3.6%) with CRA below 6 cm. Diaphragm resection had >5 times the risk for major complications (OR: 5.35; p=0.014). There was no three month mortality. Conclusion: When contiguous gross extension of disease to pelvic peritoneum and sigmoid colon is found, in patients with advanced OC, microscopic involvement of the mesorectum and intestinal wall is present in most cases making "en-bloc" resection necessary if complete cytoreduction is to be achieved. The associated morbidity is acceptable.

Background Minimally invasive surgery in cervical cancer has demonstrated in recent publications worse outcomes than open surgery. The primary objective of the SUCCOR study, a European, multicenter, retrospective, observational cohort study was to evaluate disease-free survival in patients with stage IB1 (FIGO 2009) cervical cancer undergoing open vs minimally invasive radical hysterectomy. As a secondary objective, we aimed to investigate the association between protective surgical maneuvers and the risk of relapse. Methods We obtained data from 1272 patients that underwent a radical hysterectomy by open or minimally invasive surgery for stage IB1 cervical cancer (FIGO 2009) from January 2013 to December 2014. After applying all the inclusion-exclusion criteria, we used an inverse probability weighting to construct a weighted cohort of 693 patients to compare outcomes (minimally invasive surgery vs open). The first endpoint compared disease-free survival at 4.5 years in both groups. Secondary endpoints compared overall survival among groups and the impact of the use of a uterine manipulator and protective closure of the colpotomy over the tumor in the minimally invasive surgery group. Results Mean age was 48.3 years (range; 23-83) while the mean BMI was 25.7 kg/m(2)(range; 15-49). The risk of recurrence for patients who underwent minimally invasive surgery was twice as high as that in the open surgery group (HR, 2.07; 95% CI, 1.35 to 3.15; P=0.001). Similarly, the risk of death was 2.42-times higher than in the open surgery group (HR, 2.45; 95% CI, 1.30 to 4.60, P=0.005). Patients that underwent minimally invasive surgery using a uterine manipulator had a 2.76-times higher hazard of relapse (HR, 2.76; 95% CI, 1.75 to 4.33; P<0.001) and those without the use of a uterine manipulator had similar disease-free-survival to the open surgery group (HR, 1.58; 95% CI, 0.79 to 3.15; P=0.20). Moreover, patients that underwent minimally invasive surgery with protective vaginal closure had similar rates of relapse to those who underwent open surgery (HR, 0.63; 95% CI, 0.15 to 2.59; P<0.52). Conclusions Minimally invasive surgery in cervical cancer increased the risk of relapse and death compared with open surgery. In this study, avoiding the uterine manipulator and using maneuvers to avoid tumor spread at the time of colpotomy in minimally invasive surgery was associated with similar outcomes to open surgery. Further prospective studies are warranted.

Objective: Analyze the effect on survival of secondary cytoreduction surgery (SCS) in treatment of first recurrence platinum-sensitive epithelial ovarian cancer (REOC). Methods: Retrospective analysis of patients with first REOC who had platinum time-free interval (TFIp) > 6 months and were treated either with SCS followed by chemotherapy or chemotherapy only (CT). Clinical data such as patient's performance status and number of sites with metastases were specifically assessed. The primary endpoint was overall survival (OS). Results: Seventy-one patients were treated either by SCS (n = 37) or CT (n = 34). Complete resection after SCS was achieved in 89% of patients. After a median follow-up of 51.2 months, median OS, and progression-free survival (PFS) were 68.2 and 21.6 months, respectively, for the whole series of the SCS patients had better survival and disease progression survival than the CT only patients (HR: 0.33, 95% CI: 0.17-0.6; p= 0.001) and (HR: 0.28, 95% CI: 0.15-0.5; p= 0.001), respectively. TFIp < 12 months and multiple metastases were most important prognostic factors for risk of death (HR: 7.7 and 6.2, respectively) and recurrence (HR: 5.8 and 3.8, respectively). Probability to undergo successful SCS is related to oligometastatic disease and no residual disease after first surgery (OR: 30.0 and 5.9, respectively). Conclusions: In women with REOC oligometastatic disease and no residual disease at first surgery are associated with successful SCS. In these patients oligometastatic disease and long platinum TFI are associated with improved probability of survival.

Objectives To assess the feasibility of gastrointestinal endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) for histologic confirmation of cancer recurrence in women with gynecologic cancer. Methods This work was a retrospective cohort study comprising 46 consecutive women treated for gynecologic cancer and suspected of having a deep pelvic or abdominal recurrence on ultrasound imaging, computed tomography, positron emission tomography-computed tomography, or magnetic resonance imaging, evaluated at our institution from January 2010 to December 2017. Primary cancer was ovarian (n = 22), cervical (n = 13), endometrial (n = 4), sarcoma (n = 4), and other (n = 3). All women underwent EUS examinations for locating the lesion and guiding FNA. The results of FNA (benign/malignant) were assessed. Procedure-related complications were recorded. Results The patients' mean age was 57.8 years. A total of 66 procedures were performed. Eleven women underwent 2 procedures; 2 women underwent 3 procedures; and 1 woman underwent 6 procedures at different times during the study period. In 1 case, no lesion was detected on the EUS assessment, and in 2 cases, FNA was not successful. Most lesions were located in the retroperitoneum or involved the intestine. Fine-needle aspiration could be performed in 63 cases (94.5%). Cytologic samples were adequate in 62 of 63 (98.4%). Recurrence was confirmed in 56 cases (90.3%) and ruled out in 6 (9.7%). No patient had any complication related to the procedure. Conclusions Endoscopic ultrasound-guided FNA is a minimally invasive, feasible, and safe technique for confirming pelvic/abdominal recurrence of gynecologic cancer.

Aims: Abdominal hypopressive technique (AHT) is gaining popularity as an alternative to pelvic floor muscle training (PFMT) during postpartum. Although, there is no solid evidence for its recommendation. Methods: We conducted a prospective observational cohort study in a university hospital with 105 primiparae who performed a two-month PFMT or AHT program. The aim was to compare the effectiveness of both treatments in terms of morphofunctional changes in 3D transperineal ultrasound, manometry, dynamometry, and differences in urinary incontinence symptoms (ICIQ-IU-SF) and satisfaction. Results: The average change in levator ani muscle was 1.2 mm higher in AHT group vs PFMT (95% confidence interval [CI], -2.2 to -0.2; P = .017). No statistically significant differences were shown in maximal strength changes between groups. After AHT, basal tone change was 63.0 g/cm(2) higher than PFMT (95% CI, -129 to 2.9; P = .06). A statistically significant reduction in ICIQ-IU-SF was observed after both treatments [(PFMT, -0.8 points; 95% CI, -1.4 to -0.1; P = .015), (AHT, -0.7 points; 95% CI, -1.3 to -0.1; P = .018]. AHT showed a higher median satisfaction score than PFMT (P = .004). Conclusions: This preliminary study is the first that analyses the effect of AHT vs PFMT during postpartum. The results suggest a higher improve for AHT in levator muscle thickness and satisfaction compared to PFMT. These must be considered with caution due to the limitations of the study. Further randomized clinical trials about both techniques during postpartum are required.

Objective: To compare the diagnostic performance of ultrasound and computed tomography (CT) for detecting pelvic and abdominal tumor spread in women with epithelial ovarian cancer. Methods: An observational cohort study of 93 patients (mean age 57.6 years) with an ultrasound diagnosis of adnexal mass suspected of malignancy and confirmed histologically as epithelial ovarian cancer was undertaken. In all cases, transvaginal and transabdominal ultrasound as well as CT scans were performed to assess the extent of the disease within the pelvis and abdomen prior to surgery. The exploration was systematic, analyzing 12 anatomical areas. All patients underwent surgical staging and/or cytoreductive surgery with an initial laparoscopy for assessing resectability. The surgical and pathological findings were considered as the 'reference standard'. Sensitivity and specificity of ultrasound and CT scanning were calculated for the different anatomical areas and compared using the McNemar test. Agreement between ultrasound and CT staging and the surgical stage was estimated using the weighted kappa index. Results: The tumorous stage was International Federation of Gynecology and Obstetrics (FIGO) stage I in 26 cases, stage II in 11 cases, stage III in 47 cases, and stage IV in nine cases. Excluding stages I and IIA cases (n=30), R0 (no macroscopic residual disease) was achieved in 36 women (62.2%), R1 (macroscopic residual disease <1cm) was achieved in 13 women (25.0%), and R2 (macroscopic residual disease >1cm) debulking surgery occurred in three women (5.8%). Eleven patients (11.8%) were considered not suitable for optimal debulking surgery during laparoscopic assessment. Overall sensitivity of ultrasound and CT for detecting disease was 70.3% and 60.1%, respectively, and specificity was 97.8% and 93.7%, respectively. The agreement between radiological stage and surgical stage for ultrasound (kappa index 0.69) and CT (kappa index 0.70) was good for both techniques. Overall accuracy to determine tumor stage was 71% for ultrasound and 75% for CT. Conclusion: Detailed ultrasound examination renders a similar diagnostic performance to CT for assessing pelvic/abdominal tumor spread in women with epithelial ovarian cancer.

PURPOSE: To determine the long-term results of a Phase II trial of perioperative high-dose-rate brachytherapy (PHDRB) in primary advanced or recurrent gynecological cancer. METHODS AND MATERIALS: Fifty patients with locally advanced and recurrent gynecological cancer suitable for salvage surgery were included. Unirradiated patients (n = 25) received preoperative chemoradiation followed by surgery and PHDRB (16-24 Gy). Previously irradiated patients (n = 25) received surgery and PHDRB alone (32-40 Gy). RESULTS: Median followup was 11.5 years. Eight unirradiated patients (32%) developed Grade >= 3 toxic events including two fatal events. Local and locoregional control rates at 16 years were 87.3% and 78.9%, respectively. Sixteen-year disease-free and overall survival rates were 42.9% and 46.4%, respectively. Ten previously irradiated patients (40.0%) developed Grade >= 3 adverse events, including four fatal events. Local and locoregional control rates at 14 years were 59.6% and 42.6%, respectively. Fourteen-year disease-free and overall survival rates were 16.0% and 19.2%, respectively. CONCLUSIONS: PHDRB allows effective salvage of a subset of unfavorable gynecological tumors with high-risk surgical margins. Toxicity was unacceptable at the initial dose levels but deescalation resulted in the absence of severe toxicity without a negative impact on locoregional control. A substantial percentage of patients remain alive and controlled at >10 years including a few previously irradiated cases with positive margins. (C) 2018 American Brachytherapy Society.

OBJECTIVE:
To compare diagnostic performance of preoperative transvaginal ultrasound (TVS) and intraoperative macroscopic examination for determining myometrial infiltration in women with low-risk endometrial cancer, and to estimate the agreement between the two methods.
METHODS:
This was a single-center observational study comprising women with preoperative diagnosis of well- or moderately differentiated endometrioid carcinoma of the endometrium. All women underwent preoperative TVS by a single examiner. According to the examiner's subjective impression, myometrial infiltration was stated as¿¿¿50% or¿<¿50%. Surgical staging was performed in all cases. Intraoperative macroscopic examination of the removed uterus was performed by pathologists who were unaware of the ultrasound findings, and myometrial infiltration was stated as¿¿¿50% or¿<¿50%. Definitive histological diagnosis of myometrial infiltration was made by frozen section analysis and was used as the gold standard. Sensitivity and specificity with 95% CIs were calculated for TVS and intraoperative macroscopic inspection and compared using McNemar's test. Agreement between TVS and intraoperative macroscopic inspection was estimated using Cohen's kappa index (¿) and percentage of agreement.
RESULTS:
Of 209 eligible women, 152 were ultimately included. Mean (±¿SD) age was 60.9¿±¿10.2¿years, with a range of 32-91¿years. Definitive histological diagnosis revealed that myometrial infiltration was <¿50% in 114 women and ¿¿50% in 38 women. Sensitivity and specificity of TVS for detecting deep myometrial infiltration were 81.6% and 89.5%, respectively, whereas the respective values for intraoperative macroscopic examination were 78.9% and 90.4% (McNemar's test, P¿>¿0.05 when comparing TVS and intraoperative macroscopic examination). Agreement between methods was moderate with ¿¿=¿0.54 (95%¿CI, 0.39-0.69) and percentage of agreement of 82%.
CONCLUSIONS:
Although the agreement between preoperative TVS and intraoperative macroscopic examination for detecting deep myometrial infiltration was only moderate, both methods had similar accuracy when compared with frozen section histology. Preoperative TVS might reasonably be proposed as a method for assessing myometrial infiltration as an alternative to intraoperative macroscopic examination, especially when performed by an experienced examiner and image quality is not poor.

Objectives-To evaluate the agreement of clinical examination, 2-dimensional (2D) sonography, and 3-dimensional (3D) sonography with magnetic resonance imaging (MRI) for local staging of cervical cancer.
Methods-We conducted a prospective study including women with a diagnosis of carcinoma of the cervix. All women were staged clinically and underwent 2D and 3D transvaginal sonography and MRI before treatment for assessing tumor size and parametrial, bladder, and rectal involvement using the examiner's subjective impression. Agreement between sonography and MRI was assessed by calculating the. index and percentage of agreement.
Results-Forty women were included (mean age +/- SD, 46.6 +/- 11.4 years). Eleven had early-stage (IA and IB1) disease, and 29 had advanced-stage (IB2-IVB) disease. A significant correlation for tumor size estimation was found between MRI and pelvic examination (r = 0.754; P < .001), MRI and 2D sonography (r = 0.649; P < .001), and MRI and 3D sonography (r = 0.657; P<.001). Agreement for parametrial infiltration between MRI and pelvic examination was fair (kappa = 0.26; 95% confidence interval [CI], 0.10-0.54; 62.5% agreement), between MRI and 2D sonography was moderate (kappa = 0.41; 95% CI, 0.15-0.66; 70.0% agreement), and between MRI and 3D sonography was good (kappa = 0.60; 95% CI, 0.35-0.85; 80.0% agreement). Agreement for bladder involvement between MRI and pelvic examination was moderate (kappa = 0.48; 95% CI, 0.10-0.99; 95.0% agreement), between MRI and 2D sonography was moderate (kappa = 0.48; 95% CI, 0.10-0.99; 95.0% agreement), and between MRI and 3D sonography was very good (kappa = 0.84; 95% CI, 0.55-1.0; 97.5% agreement). Agreement for rectal involvement was not calculated because of the very small number of cases.
Conclusions-Three-dimensional sonography showed good agreement with MRI for assessing parametrial infiltration and bladder involvement in cervical cancer.

ObjectiveTo evaluate the contribution of three-dimensional (3D) power Doppler angiography (3D-PDA) to the differential diagnosis of adnexal masses.
MethodsThis was a prospective study in women diagnosed with a persistent adnexal mass and subsequently scheduled for surgery in a tertiary university hospital. All women were evaluated by transvaginal/transrectal ultrasound according to a predetermined three-step protocol, with transabdominal ultrasound being performed in some cases. First, morphological evaluation of the mass was performed using gray-scale pattern recognition' (first step). Lesions diagnosed as having a benign pattern were considered as being at low risk of malignancy whereas tumors with solid components, ascites and/or signs of carcinomatosis were considered as being at high risk of malignancy. In both cases no further test was performed and a decision regarding clinical management, either for follow-up or surgery, was taken. Tumors with solid components but without signs of ascites or carcinomatosis were considered as being at intermediate risk of malignancy. These lesions were assessed by two-dimensional (2D) PDA to evaluate tumor vascularity (color score) (second step). Solid tumors with a color score of 1 or 2 were considered as benign and no further test was performed, while tumors with a color score of 2, 3 or 4 within solid components or a color score of 3 or 4 in the case of a solid tumor were considered as malignant. The latter group underwent 3D-PDA a

Objective To assess the correlation between intratumoral vascularization using three-dimensional power Doppler angiography (3D-PDA) and several histological tumor characteristics in a series of patients with endometrial carcinoma.
Methods Ninety-nine women (mean age, 61.7 (range, 31-84) years) diagnosed as having endometrial cancer were assessed by transvaginal 3D-PDA before surgical staging. Endometrial volume (E V,) and 3D-PDA vascular indices (vascularization index (VI), flow index (FI) and vascularization flow index (VFI)) were calculated using the Virtual Organ Computer-aided AnaLysis (VOCAL (TM)) method. All patients were surgically staged. Individual tumor features such as histological type, tumor grade, myometrial infiltration depth, lymph-vascular space involvement, cervical involvement, lymph node metastases and tumor stage were considered for analysis. Multivariate logistic regression (MLR) analysis was used to determine which 3D-PDA parameters were independently associated with each histological characteristic.
Results MLR analysis showed that only EV and VI were independently associated with myometrial infiltration (EV: odds ratio (OR), 1.119 (95% CI, 1.025-1.221), P = 0.012; VI: OR, 1.127 (95% CI, 1.063-1.195), P = 0.001) and tumor stage (EV: OR, 1.103 (95% CI, 1.012-1.202), P = 0.025; VI: OR, 1.120 (95% CI, 1.057-1.187), P = 0.001), only VI was independently associated with tumor grade (OR, 1.056 (95% CI, 1.023-1.091), P = 0.001) and only EV was independently associated with lymph node metastases (OR, 1.086 (95% CI, 1.017-1.161), P = 0.001).
Conclusion 3D-PDA analysis of tumor vascularization in endometrial cancer correlates with some prognostic histological characteristics.
