Combining multimodal diffusion-weighted imaging and morphological parameters for detecting lymph node metastasis in cervical cancer. Abdom Radiol (NY) 2024:10.1007/s00261-024-04494-3. [PMID: 38990301 DOI: 10.1007/s00261-024-04494-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2024] [Revised: 07/05/2024] [Accepted: 07/06/2024] [Indexed: 07/12/2024]
Abstract
BACKGROUND Accurate detection of lymph node metastasis (LNM) is crucial for determining the tumor stage, selecting optimal treatment, and estimating the prognosis for cervical cancer. This study aimed to assess the diagnostic efficacy of multimodal diffusion-weighted imaging (DWI) and morphological parameters alone or in combination, for detecting LNM in cervical cancer. METHODS In this prospective study, we enrolled consecutive cervical cancer patients who received multimodal DWI (conventional DWI, intravoxel incoherent motion DWI, and diffusion kurtosis imaging) before treatment from June 2022 to June 2023. The largest lymph node (LN) observed on each side on imaging was matched with that detected on pathology to improve the accuracy of LN matching. Comparison of the diffusion and morphological parameters of LNs and the primary tumor between the positive and negative LN groups. A combined diagnostic model was constructed using multivariate logistic regression, and the diagnostic performance was evaluated using receiver operating characteristic curves. RESULTS A total of 93 cervical cancer patients were enrolled: 35 with LNM (48 positive LNs were collected), and 58 without LNM (116 negative LNs were collected). The area under the curve (AUC) values for the apparent diffusion coefficient, diffusion coefficient, mean diffusivity, mean kurtosis, long-axis diameter, short-axis diameter of LNs, and the largest primary tumor diameter were 0.716, 0.720, 0.716, 0.723, 0.726, 0.798, and 0.744, respectively. Independent risk factors included the diffusion coefficient, mean kurtosis, short-axis diameter of LNs, and the largest primary tumor diameter. The AUC value of the combined model based on the independent risk factors was 0.920, superior to the AUC values of all the parameters mentioned above. CONCLUSION Combining multimodal DWI and morphological parameters improved the diagnostic efficacy for detecting cervical cancer LNM than using either alone.

Vascular clips for preventing lymphocele and symptomatic lymphocele in patients with gynecologic malignancies after laparoscopic pelvic lymphadenectomy. J Minim Invasive Gynecol 2024:S1553-4650(24)00276-0. [PMID: 38944337 DOI: 10.1016/j.jmig.2024.06.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Revised: 06/04/2024] [Accepted: 06/24/2024] [Indexed: 07/01/2024]
Abstract
STUDY OBJECTIVE To evaluate the effectiveness of using vascular clips to seal targeted lymphatics in gynecological malignancies for the prevention of postoperative pelvic lymphocele and symptomatic lymphocele after laparoscopic pelvic lymphadenectomy. DESIGN Retrospective analysis. SETTING Single-center academic hospital. PATIENTS In total, 217 patients with gynecological malignancies were included. INTERVENTIONS Patients were classified into two groups: group 1 (vascular clips were used to seal the targeted lymphatics) and group 2 (electrothermal instruments were used to seal the targeted lymphatics). The patients were followed up 4-6 weeks after surgery to evaluate the incidence of lymphoceles by ultrasound or CT. Symptomatic lymphoceles are defined as those that cause infection, deep vein thrombosis with or without swelling of the extremities, edema (swelling) of the extremities or perineum, hydronephrosis and/or moderate to severe pain. MEASUREMENT AND MAIN RESULTS One hundred and thirteen patients were enrolled in group 1, and 104 patients were enrolled in group 2. Lymphoceles were observed in 46 (21.2%) patients. Fewer lymphoceles occurred in group 1 than in group 2 [8 (7.1%) vs. 38 (36.5%), p < 0.001]. The percentage of significantly sized lymphoceles was lower in group 1 than that in group 2 [4 (3.5%) vs. 30 (28.8%), p < 0.001]. Symptomatic lymphoceles occurred in 18 patients (8.3%), and only one (1.0%) occurred in group 1, while 17 (16.3%) occurred in group 2 (p < 0.001). A multivariate analysis revealed that vascular clips were the only independent factor for preventing lymphocele (OR = 7.65, 95% CI = [3.30, 17.13], p < 0.001) and symptomatic lymphocele (OR = 22.03, 95% CI = [2.84, 170.63], p = 0.003). CONCLUSIONS The results indicate that the use of vascular clips may be useful for the prevention of the development of lymphocele and symptomatic lymphocele secondary to pelvic lymphadenectomy performed via laparoscopy.

Abstract
PURPOSE OF REVIEW Sentinel lymph node biopsy (SLNB) is a widely used technique in other gynaecological tumours but has not yet been implemented as the gold standard technique for nodal staging in cervical cancer. Since the majority of evidence is derived from retrospective studies, this review aims to summarize the most recent evidence on this relevant topic. RECENT FINDINGS SLNB has demonstrated to be a well tolerated technique for lymph node staging in early-stage cervical cancer patients with promising future as exclusive lymph node assessment method avoiding full lymphadenectomy. Moreover, it allows ultrastaging and unfrequent drainage identification, which enables the detection of patients at a high risk of recurrence who would otherwise remain unnoticed. When compared with pelvic lymphadenectomy, SLNB is also associated with less intraoperative and postoperative complications, especially in terms of lymphedema formation. SUMMARY The available evidence suggests that SLNB offers numerous advantages over the standard pelvic lymphadenectomy reducing morbidity rates and increasing diagnostic accuracy. Three ongoing prospective trials will likely answer the controversies over these questions.

Abstract
Background Lymphadenectomy plays an essential role in the staging protocols for gynecologic cancers, as recommended by International Federation of Gynecology and Obstetrics (FIGO). While its benefits vary, complications may arise during intra-operative, acute post-operative, or long-term periods. Notably, lymphadenectomy-associated systemic morbidity and specific complications such as lymphocele and lymphedema have been reported. Methods This retrospective study involved 399 patients with cervical, endometrial, and ovarian cancers who underwent pelvic and para-aortic lymphadenectomy. The follow-up period was at least 3 months. Intra-operative complications encompassed adjacent organ injury and significant blood loss, while acute post-operative complications occurred within 29 days. Post-30-day complications included lymphocele and lymphedema. Logistic regression analysis identified predictors for complications. Results The overall complication rate was 42.4%, with intra-operative, acute post-operative, and long-term rates of 26.1%, 11.0%, and 14.0%, respectively. Predictors for overall complications included laparotomy, positive lymph nodes, and operative time > 240 min. For intra-operative complications, age > 60 years, laparotomy, positive lymph nodes, and operative time > 240 min were significant predictors. Symptomatic lymphocele and lymphedema occurred in 6.0% and 2.0% of patients, respectively, mainly in the long-term period. Conclusion Although the overall complication rate after gynecologic surgery was found to be almost half of all cases, the rate of severe complications was low. Additionally, the rates of symptomatic lymphocele and lymphedema were low. Lymphadenectomy in gynecologic cancer surgery can be performed safely.

Abstract
Objective The purpose of this retrospective study was to establish a combined model based on ultrasound (US)-radiomics and clinical factors to predict patients with stage I cervical cancer (CC) before surgery. Materials and methods A total of 209 CC patients who had cervical lesions found by transvaginal sonography (TVS) from the First Affiliated Hospital of Anhui Medical University were retrospectively reviewed, patients were divided into the training set (n = 146) and internal validation set (n = 63), and 52 CC patients from Anhui Provincial Maternity and Child Health Hospital and Nanchong Central Hospital were taken as the external validation set. The clinical independent predictors were selected by univariate and multivariate logistic regression analyses. US-radiomics features were extracted from US images. After selecting the most significant features by univariate analysis, Spearman's correlation analysis, and the least absolute shrinkage and selection operator (LASSO) algorithm, six machine learning (ML) algorithms were used to build the radiomics model. Next, the ability of the clinical, US-radiomics, and clinical US-radiomics combined model was compared to diagnose stage I CC. Finally, the Shapley additive explanations (SHAP) method was used to explain the contribution of each feature. Results Long diameter of the cervical lesion (L) and squamous cell carcinoma-associated antigen (SCCa) were independent clinical predictors of stage I CC. The eXtreme Gradient Boosting (Xgboost) model performed the best among the six ML radiomics models, with area under the curve (AUC) values in the training, internal validation, and external validation sets being 0.778, 0.751, and 0.751, respectively. In the final three models, the combined model based on clinical features and rad-score showed good discriminative power, with AUC values in the training, internal validation, and external validation sets being 0.837, 0.828, and 0.839, respectively. The decision curve analysis validated the clinical utility of the combined nomogram. The SHAP algorithm illustrates the contribution of each feature in the combined model. Conclusion We established an interpretable combined model to predict stage I CC. This non-invasive prediction method may be used for the preoperative identification of patients with stage I CC.

Abstract
PURPOSE A systematic review investigated the effectiveness of physical activity in alleviating lower limb lymphedema among patients with gynecological cancer after surgery. METHODS A systematic review of randomized controlled trials and quasi-experimental designs was conducted. Six databases, Cinahl, Cochrane, Embase, Medline, Scopus, and Web of Science, were searched for relevant publications from inception to October 2022 and updated in January 2024. RevMan software was used to perform meta-analysis using a random-effects model. RESULTS Seven studies (5 randomized controlled trials) containing 261 subjects were synthesized. The risk of bias was low in the included studies. The exercise interventions for lower limb lymphedema included active, aerobic, aquatic, and weight-lifting exercises. Meta-analyses showed that active exercise had no effect on lymphedema symptoms of limb volume, pain, and heaviness. However, the effectiveness of exercise on limb volume had subthreshold borderline significance in 2 studies (standardized mean difference = 0.43, 95% confidence interval - 0.01, 0.88; I2 = 0%, p = 0.06). Three studies found that lymphedema symptoms were significantly improved after exercise interventions. The adherence rate of the exercise was 77-100%, with the only complication being cellulitis. CONCLUSIONS Although the meta-analysis does not reveal a significant effect, the systematic review study demonstrated that exercise is feasible, safe, and has a clinical effect on alleviating lymphedema-related symptoms of women following gynecological cancer surgery.

Abstract
BACKGROUND Sentinel lymph node biopsy represents an alternative to pelvic lymphadenectomy for lymph node staging of early-stage cervical carcinoma, but prospective evidence on long-term oncological safety of sentinel lymph node biopsy alone versus pelvic lymphadenectomy is missing. OBJECTIVE To investigate, with this meta-analysis, the impact of sentinel lymph node biopsy alone versus pelvic lymphadenectomy on survival for patients with early-stage cervical cancer. METHODS A systematic literature review was performed. We excluded studies in which pelvic lymphadenectomy was systematically performed after every sentinel lymph node biopsy, including only articles where pelvic lymphadenectomy was performed because sentinel lymph node biopsy was not conclusive. A meta-analysis was carried out combining 5-year disease-free survival and overall survival rates with a random and fixed effect model. Heterogeneity was tested using the Cochran Χ2 test and quantified with Higgins information I2. RESULTS The search of databases and registers found 927 items and six articles (two retrospective and four prospective). The median time of follow-up was 34.8 months (range 13-53). Overall common effect disease-free survival was 98% while random effect disease-free survival was 94%. Overall heterogeneity was 77%. A subgroup analysis was applied, dividing studies into one group including sentinel lymph node biopsy negative data only (common effect disease-free survival 91%; random effect disease-free survival 90%), and one group with a negative and positive sentinel lymph node biopsy (common effect disease-free survival 98%; random effect disease-free survival 96%). In the analysis of overall survival, positive and negative sentinel lymph node biopsy cases were examined together (common and random effect overall survival 99%). Ultrastaging did not affect disease-free survival (common and random effect disease-free survival 92% in the ultrastaging group vs common effect disease-free survival 99% and random effect disease-free survival 96% in the non-ultrastaging group). CONCLUSIONS Both 5-year disease-free survival and overall survival rate after sentinel lymph node biopsy alone are higher than 90% and do not differ from pelvic lymphadenectomy survival data. Ultrastaging did not impact survival.

Abstract
BACKGROUNDS Gynaecological cancer survivors may develop lower limb lymphoedema after surgery, which negatively impacts quality of life. The purposes of this study were (1) to assess the levels of symptom distress, depression, body image, and health-related quality of life (HRQoL); (2) to recognize factors associated with HRQoL related in gynaecologic cancer survivors with lower limb lymphoedema. METHODS A cross-sectional study was conducted with convenience sampling of gynaecologic cancer survivors with lower limb lymphoedema. Gynaecologic cancer survivors were assessed for symptom distress, depression, body image, and HRQoL. Multiple regression analysis was conducted to recognize the factors associated with HRQoL. Independent-samples t-test was used to compare symptom distress, depression, body image, and HRQoL by grade of lymphoedema. RESULTS The most common distressing symptoms of lower limb lymphoedema were lower extremity oedema, lower extremity tightness, and lower extremity stiffness. Worse HRQoL was associated with more symptom distress, less satisfaction with body image, a high grade of lymphoedema, and a longer duration of lower limb lymphoedema. These factors explained 76.5% of the variance in HRQoL. Gynaecologic cancer survivors with late grade lymphoedema experienced lower HRQoL and higher levels of symptom distress, depression, and greater dissatisfaction with body image than those who had early grade lymphoedema. CONCLUSIONS Symptom distress had the strongest association with overall HRQoL and with all individual domains of HRQoL, except mental function. These results suggest that educating gynaecologic cancer survivors to assess lower limb lymphoedema-related problems, providing symptom management, and guiding survivors in physical activity to relieve lower extremity discomfort can improve HRQoL.

Abstract
BACKGROUND Noninvasive and accurate prediction of lymph node metastasis (LNM) is very important for patients with early-stage cervical cancer (ECC). Our study aimed to investigate the accuracy and sensitivity of radiomics models with features extracted from both intra- and peritumoral regions in magnetic resonance imaging (MRI) with T2 weighted imaging (T2WI) and diffusion weighted imaging (DWI) for predicting LNM. METHODS A total of 247 ECC patients with confirmed lymph node status were enrolled retrospectively and randomly divided into training (n = 172) and testing sets (n = 75). Radiomics features were extracted from both intra- and peritumoral regions with different expansion dimensions (3, 5, and 7 mm) in T2WI and DWI. Radiomics signature and combined radiomics models were constructed with selected features. A nomogram was also constructed by combining radiomics model with clinical factors for predicting LNM. RESULTS The area under curves (AUCs) of radiomics signature with features from tumors in T2WI and DWI were 0.841 vs. 0.791 and 0.820 vs. 0.771 in the training and testing sets, respectively. Combining radiomics features from tumors in the T2WI, DWI and peritumoral 3 mm expansion in T2WI achieved the best performance with an AUC of 0.868 and 0.846 in the training and testing sets, respectively. A nomogram combining age and maximum tumor diameter (MTD) with radiomics signature achieved a C-index of 0.884 in the prediction of LNM for ECC. CONCLUSIONS Radiomics features extracted from both intra- and peritumoral regions in T2WI and DWI are feasible and promising for the preoperative prediction of LNM for patients with ECC.

Abstract
PURPOSE Lymph node involvement in cancer of the uterine cervix is a major independent prognostic factor for overall survival. The aim of our study was to examine the lymphatic drainage regions of the different parts of the uterine cervix. METHODS An anatomical study of fresh cadavers was conducted by injecting patent blue in the anterior or posterior lip of the uterine cervix and dissecting drainage regions. Furthermore, a retrospective radiological and pathological studies were conducted on patients who were treated for early-stage cancer of the uterine cervix with lymph node involvement. Radiological analysis of pre-therapeutic MRIs and/or pathological analysis of surgical specimens showed the precise location of the tumour. A correlation between the anatomy of the primary lesion site and the lymphatic area involved was established. RESULTS We administered 15 cadaveric injections: 8 in the anterior lip of the uterine cervix and 7 in the posterior one. For 100% of the anterior lip injections, lymphatic drainage was bilateral ileo-obturator (n = 8/8) combined with bilateral parametrial drainage. For the posterior injections, there was never any ileo-obturator drainage, and 6 of the 7 (75%) posterior injections drained in the posterior uterine serosa. Concerning the clinical study, we included 21 patients. We observed a non-significant tendency towards bilateral lymph node involvement when the tumour of the anterior lip. CONCLUSION Physiological lymphatic drainage of the uterine cervix presents anatomical specificities, depending on the structure studied, anterior or posterior lip of the cervix. Better knowledge of these specificities should allow personalized surgery for each patient.

Abstract
OBJECTIVE To compare the value of whole-lesion apparent diffusion coefficient (ADC) histogram analysis derived from readout-segmented echo-planar imaging (RS-EPI) and single-shot echo-planar imaging (SS-EPI) diffusion-weighted imaging (DWI) in evaluating normal-sized lymph node metastasis (LNM) in cervical cancer. METHODS Seventy-six pathologically confirmed cervical cancer patients (stages IB and IIA) were enrolled, including 61 patients with non-LNM (group A) and 15 patients with normal-sized LNM (group B). The recorded tumor volume on T2-weighted imaging was the reference against which both DWIs were evaluated. Each ADC histogram parameter (including ADCmax, ADC90, ADCmedian, ADCmean, ADC10, ADCmin, ADCskewness, ADCkurtosis, and ADCentropy) was compared between SS-EPI and RS-EPI and between the 2 groups. RESULTS There was no significant difference in tumor volume between the 2 DWIs and T2-weighted imaging (both P > 0.05). Higher ADCmax and ADCentropy but lower ADC10, ADCmin and ADCskewness were found in SS-EPI than those in RS-EPI (all P < 0.05). For SS-EPI, lower ADC90 and higher ADCkurtosis were found in group B than those in group A (both P < 0.05). For RS-EPI, lower ADC90 and higher ADCkurtosis and ADCentropy were found in group B than those in group A (all P < 0.05). Readout-segmented echo-planar imaging ADCkurtosis showed the highest area under the curve of 0.792 in the differentiation of the 2 groups (sensitivity, 80%; specificity, 73.77%). CONCLUSIONS Compared with SS-EPI, the ADC histogram parameters derived from RS-EPI were more accurate, and ADCkurtosis held great potential in differentiating normal-sized LNM in cervical cancer.

Abstract
Current clinical treatments on lymphedema provide promising results, but also result in donor site morbidities. The establishment of a microenvironment optimized for lymphangiogenesis can be an alternative way to enhance lymphatic tissue formation. Hemodynamic flow stimuli have been confirmed to have an influential effect on angiogenesis in tissue engineering, but not on lymphatic vessel formation. Here, the three in vivo scaffolds generated from different blood stimuli in the subcutaneous layer, in the flow through pedicle, and in an arterio-venous (AV) loop model, were created to investigate potential of lymphangiogenesis of scaffolds containing lymphatic endothelial cells (LECs). Our results indicated that AV loop model displayed better lymphangiogenesis in comparison to the other two models with slower flow or no stimuli. Other than hemodynamic force, the supplement of LECs is required for lymphatic vessel regeneration. The in vivo scaffold generated from AV loop model provides an effective approach for engineering lymphatic tissue in the clinical treatment of lymphedema.

Abstract
INTRODUCTION This retrospective study aims to investigate the feasibility of using carbon nanoparticles to detect sentinel lymph nodes (SLNs) in cervical cancer. METHODS This study involved 174 patients with cervical cancer. Cervix tissues adjacent to the cancer were injected with 1 mL of carbon nanoparticles (CNPs) at the 3 and 9 o'clock positions according to the instructions. The pelvic lymph nodes were then dissected, and the black-stained sentinel lymph nodes were sectioned for pathological examination. RESULTS Of 174 cases, 88.5% of patients (154/174) had at least 1 sentinel lymph node, and 131 patients (75.29%) had bilateral pelvic sentinel lymph nodes. The left pelvic lymph node was the most common sentinel lymph node (34.16%). At least 1 sentinel lymph node was observed in 285 out of 348 hemipelvises, with a detection rate of a side-specific sentinel lymph node of 81.89%. In total, 47 hemipelvises had metastasis of the lymph node, and 33 involved the sentinel lymph node, with a sensitivity of 70.21% and a false-negative rate of 29.79%. There were 238 hemipelvises with no metastasis of the lymph node, as well as negative sentinel lymph nodes, with a specificity of 100% and a negative predictive value of 94.44%. The univariate analysis demonstrated that risk factors included tumor size (OR .598, 95% CI: .369-.970) and deep stromal invasion (OR .381, 95% CI: .187-.779). The deep stromal invasion was the only variable for the false-negative detection of a sentinel lymph node. CONCLUSION Sentinel lymph node mapping with carbon nanoparticles might be applied to predict the metastasis of pelvic lymph nodes in cervical cancer. However, tumor size and deep stromal invasion might negative influence the detection rate of SLN.

Abstract
BACKGROUND It is difficult to predict normal-sized lymph node metastasis (LNM) in cervical cancer clinically. We aimed to investigate the feasibility of using deep learning (DL) nomogram based on readout segmentation of long variable echo-trains diffusion weighted imaging (RESOLVE-DWI) and related patient information to preoperatively predict normal-sized LNM in patients with cervical cancer. METHODS A dataset of MR images [RESOLVE-DWI and apparent diffusion coefficient (ADC)] and patient information (age, tumor size, International Federation of Gynecology and Obstetrics stage, ADC value and squamous cell carcinoma antigen level) of 169 patients with cervical cancer between November 2013 and January 2022 were retrospectively collected. The LNM status was determined by final histopathology. The collected studies were randomly divided into a development cohort (n = 126) and a test cohort (n = 43). A single-channel convolutional neural network (CNN) and a multi-channel CNN based on ResNeSt architectures were proposed for predicting normal-sized LNM from single or multi modalities of MR images, respectively. A DL nomogram was constructed by incorporating the clinical information and the multi-channel CNN. These models' performance was analyzed by the receiver operating characteristic analysis in the test cohort. RESULTS Compared to the single-channel CNN model using RESOLVE-DWI and ADC respectively, the multi-channel CNN model that integrating both two MR modalities showed improved performance in development cohort [AUC 0.848; 95% confidence interval (CI) 0.774-0.906] and test cohort (AUC 0.767; 95% CI 0.613-0.882). The DL nomogram showed the best performance in development cohort (AUC 0.890; 95% CI 0.821-0.938) and test cohort (AUC 0.844; 95% CI 0.701-0.936). CONCLUSION The DL nomogram incorporating RESOLVE-DWI and clinical information has the potential to preoperatively predict normal-sized LNM of cervical cancer.

Abstract
Millions of people worldwide suffer from lymphedema. In developed nations, lymphedema most commonly stems secondarily from oncologic treatment, but may also result from trauma. More recently, lymphedema has been identified in patients after gender-affirmation phalloplasty reconstruction. Regardless of the etiology, the underlying pathophysiology involves blockage of lymphatic flow, resulting in lymph stasis, thus triggering a cascade of inflammation culminating in fibrosis and adipose deposition. Recent technical advances led to the refinement of physiologic and reductive surgeries-including lymphovenous anastomosis and free functional lymphatic transfer, which collectively encompass a variety of flap procedures including lymph node transfer, lymph channel transfer, and lymphatic system transfer. This article provides a summary of our approach in the assessment and management of the lymphedema patient, including detailed intraoperative photography and imaging, in addition to advanced technical considerations in physiologic reconstruction.

Abstract
Objective We aimed to investigate the association of examined lymph node (ELN) number with lymph node status and long-term survival in FIGO stage IB-IIA cervical squamous cell carcinoma(CSCC) and to determine the minimum number of ELN associated with survival improvement. Method Data from the Surveillance, Epidemiology, and End Results Program (SEER) database of FIGO stage IB-IIA CSCC patients undergoing hysterectomy and pelvic lymphadenectomy in 2004-2016 were analyzed to explore the relationship between ELN number and lymph node status and overall survival (OS) by using the multivariable approach. The estimated probability of falsely identifying a patient as node-negative and the hazard ratios (HRs) for each ELN was fitted with a LOWESS smoother, and the structural breakpoints were determined. X-tile software was used to determine the optimal cutoff value for ELNs. Results A total of 2627 patients were analyzed. The optimal cutoff value of the ELN number was identified as 7 based on the results of X-tile software. The structural breakpoints according to the associations between the number of ELNs and the estimated risk of false-negative lymph node dissection and HRs for overall survival were 9 and 8, respectively. The multivariate analysis indicated that ELN number was an independent prognostic factor for OS, both as a continuous or categorical variable. To further explore the effect of more ELNs on survival, another cutoff value of 17 was chosen to compare the survival curves of patients. The multivariate-adjusted COX model showed that patients with ELN<8 had a significantly higher risk of death than those with ELN8-17 (HR=1.447, 95% CI =1.075-1.947, p=0.015), but there was no significant difference in overall survival between patients with ELN>17 and patients with ELN8-17 (HR=0.822, 95%CI =0.665-1.016, p=0.070). Conclusion A sufficient number of ELNs was associated with better long-term survival in FIGO stage IB-IIA CSCC. At least 8 ELNs need to be examined for prognostic stratification. Excessive lymph node dissection (ELN>17) may not confer additional survival benefits.

Abstract
Objective Cervical cancer (CC) is one of the main causes of death among gynecological malignancies. Patients with CC with lymph node metastasis (LNM) have poor prognoses. We investigated the risk factors and prognosis of LNM in patients with CC patients using data from the SEER database. Methods We collected the information of cervical cancer patients registered in SEER database from 2010 to 2015. The dataset was divided into a training set and a validation set at a 7:3 ratio. LASSO regression analysis was used to evaluate risk factors for LNM in patients with CC. Using the results, we established a nomogram prediction model. C-index, ROC curves, calibration curves, decision curve analysis, and clinical impact curves were used to evaluate the prediction performance of the model. Results We included 14,356 patients with CC in the analysis. Among these, 3997 patients were diagnosed with LNM. A training set (10,050 cases) and a validation set (4306 cases) were used for the following analysis. We established nomogram LNM prediction models for the patients with T1-2-stage CC. The C-indices for the internal and external validations of the prediction models were 0.758 and 0.744, respectively. In addition, we established a prognostic nomogram for all CC patients with LNM, and the internal and external validation C-indices were 0.763 and 0.737. Conclusion We constructed a quantitative and visual predictive nomogram that predicted prognosis of patients with LNM in CC to provide clinicians with a reference for diagnosis and treatment.

Abstract
OBJECTIVE The goal of this study was to assess the feasibility and safety of a retrograde extraperitoneal trans-inguinal novel approach to pelvic lymphadenectomy in vulvar cancer patients. The secondary objectives were to assess complications (early and late) and oncological outcomes. METHODS In this pilot study, all patients referred to our institution from November 2019 to May 2021 were evaluated. The inclusion criteria were patients diagnosed with primary/recurrent vulvar cancer and who were candidates for concomitant groin and pelvic lymph node dissection. A consecutive sampling was planned during the study period. After conventional inguino-femoral lymph nodal dissection, ipsilateral extraperitoneal trans-inguinal pelvic lymphadenectomy (TRIPLE) was performed through a groin incision. Clinical data, type of treatment, perioperative complications, and follow-up were evaluated. RESULTS 13 patients (8 primary, 5 recurrent vulvar cancer) underwent 16 TRIPLE procedures (10 unilateral, 3 bilateral). The median age was 69 years (range 58-93 years); 8 patients had comorbidities (61.5%). Up front locoregional radiotherapy was previously performed in two cases (15.4%). The pathology report showed metastatic lymph nodes in 20 (87%) groins and 11 (68.8%) pelvic sites; the mean number of removed and metastatic pelvic lymph nodes was 12.1 (range 5-33) and 2.9 (range 0-18), respectively. No intra-operative site-specific complications occurred. One (5.9%) post-operative site-specific complication was reported (pelvic abscess, grade 2), which was treated with antibiotics. One patient died due to concomitant pneumonia. No unilateral pelvic lymph node recurrence occurred during follow-up (median 13 months, range 2-43 months); 3 patients (23.1%) had distant site recurrence (median disease-free survival 9 months). CONCLUSIONS TRIPLE seems to be a feasible and safe technique, providing adequate lymph node dissection. Despite being a high-risk and fragile population, morbidity was similar to previously reported data for conventional mini-invasive approaches. Prospective larger comparative series are necessary.

Current Standards in the Management of Early and Locally Advanced Cervical Cancer: Update on the Benefit of Neoadjuvant/Adjuvant Strategies. Cancers (Basel) 2022; 14:cancers14102449. [PMID: 35626051 PMCID: PMC9139662 DOI: 10.3390/cancers14102449] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 05/13/2022] [Accepted: 05/14/2022] [Indexed: 12/04/2022] Open
Abstract
Simple Summary Cervical cancers is a human papillomavirus infection-induced gynecologic cancer. Due to the uneven access to prevention measures in the world, it is still a leading cause of cancer death in women in low- and middle-income countries. The mainstay of treatment for early-stage cervical cancers is upfront surgery. Clinical trials confirmed the place of adjuvant radiotherapy to improve disease control, but also highlighted the need for a careful selection of patients prior to surgery, in order to avoid the cumulative morbidities of each treatment. In locally advanced cervical cancers, the standard of care remains concurrent pelvic chemoradiotherapy followed by an image-guided adaptive brachytherapy boost allowing for dose escalation and leading to a very high probability of local control. Systemic failures remain a major concern, and neoadjuvant or adjuvant approaches in this context are discussed in the light of recent literature. Abstract Globally, cervical cancers continue to be one of the leading causes of cancer-related deaths. The primary treatment of patients with early-stage disease includes surgery or radiation therapy with or without chemotherapy. The main challenge in treating these patients is to maintain a curative approach and limit treatment-related morbidity. Traditionally, inoperable patients are treated with radiation therapy solely and operable patients undergo upfront surgery followed by adjuvant (chemo) radiotherapy in cases with poor histopathological prognostic features. Patients with locally advanced cervical cancers are treated with concurrent chemoradiotherapy followed by an image-guided brachytherapy boost. In these patients, the main pattern of failure is distant relapse, encouraging intensification of systemic treatments to improve disease control. Ongoing trials are evaluating immunotherapy in locally advanced tumours following its encouraging efficacy reported in the recurrent and metastatic settings. In this article, clinical evidence of neoadjuvant and adjuvant treatments in cervical cancer patients is reviewed, with a focus on potential strategies to improve patients’ outcome and minimize treatment-related morbidity.

Abstract
Background Uterine sarcomas are rare subtypes of primary urogenital tumours and need tailored treatment. This study aimed to examine the impact of diagnosis and treatment on health-related quality of life (HRQoL) in patients with uterine sarcoma and measures available to assess HRQoL in this group. Methods Thirteen patients with uterine sarcoma and 23 health care professionals were purposively sampled from sarcoma reference centers and participated in a semi-structured interview exploring HRQoL. Patients were also asked to review the EORTC QLQ-C30 and EORTC QLQ-EN24 for relevance. Data were analysed using thematic analysis and descriptive statistics. Results The most commonly reported physical health issues were related to sexual dysfunction and urological symptoms. Hormone-related issues and gastrointestinal symptoms were also identified. Cancer-generic issues such as functional problems, fatigue, pain, and treatment-related adverse effects were also reported. Regarding mental health, fears (about having sex, of recurrence, or of death), altered body-image, and dealing with lacking knowledge regarding sarcoma had an impact on HRQoL. Social health issues were related to the impact on relationships with others, limitations in undertaking activities, loss of independence, changes in work or study capacity, and financial difficulties. Most of the items of the EORTC QLQ-C30 and EORTC QLQ-EN24 questionnaires were rated as relevant. Questions about lack of knowledge about sarcoma, shock of diagnosis, and menopausal symptoms were lacking from existing measures. Conclusions Uterine sarcoma patients experience a variety of concerns covering the physical, mental, and social domains of HRQoL that are in the main EORTC instruments, but not all of them. Combining cancer-generic, location- and sarcoma-specific items is recommended to assess HRQoL in this patient group. Trial registration NCT04071704.

Abstract
Vascularized lymph node transplantation (VLNT) has shown inspiring results for the treatment of lymphedema. Nevertheless, it remains unclear how VLNT restores lymphatic drainage and whether or not immunity recovers after surgery. Hindlimb lymphedema model was created using rats with extensive groin and popliteal lymph node removable following with radiotherapy, and the lymphedema was confirmed using indocyanine green (ICG) lymphangiography and micro‐computer tomography for volume measurement. VLNT was performed 1 month later. Volume measurement, ICG lymphangiography, histology, and immune reaction were done 1 month after surgery. VLNT successfully reduced the volume of the lymphedema hindlimb, restored lymphatic drainage function with proven lymphatic channel, and reduced lymphedema‐related inflammation and fibrosis. It promotes lymphangiogenesis shown from ICG lymphangiography, histology, and enhanced lymphangiogenesis gene expression. Dendritic cell trafficking via the regenerated lymphatic channels was successfully restored, and maintained systemic immune response was proved using dinitrofluorobenzene sensitization and challenge. VLNT effectively reduces lymphedema and promotes lymphatic regeneration in the capillary lymphatic but not the collecting lymphatic vessels. Along with the re‐established lymphatic system was the restoration of immune function locally and systemically. This correlated to clinical experience regarding the reduction of swelling and infection episodes after VLNT in lymphedema patients.

Abstract
Introduction Early endometrial cancer is primarily treated surgically via hysterectomy, adenectomy and, depending on tumor stage and subtype, lymphadenectomy. Systematic lymph node dissection is known to cause surgical complications. The aim of the present study was to investigate morbidity and mortality rates associated with lymphadenectomy in patients with endometrial cancer who underwent surgery in a routine clinical setting.
Methods We collected data from 232 patients who were operated for endometrial carcinoma between 2006 and 2018 at the University of Lubeck, Germany. Surgical complications were viewed in relation to surgical risk factors. Additionally, a questionnaire concerning long-term lymphatic complications and survival was completed. Survival was compared between patients who underwent lymphadenectomy (group I) and those who did not (group II).
Results Patients in group I needed revision surgery significantly more often due to postoperative complications (such as lymphoceles) compared to those in group II (p = 0.01). The results indicate more serious complications in patients who underwent a systematic lymphadenectomy and in those with lymph node metastases. 15% of patients who underwent a systematic lymphadenectomy had lymph node metastases. Recurrences occurred in 12.5% of cases and were significantly more frequent in patients who had undergone a lymphadenectomy, even if the lymph nodes were negative (p = 0.02). A comparison of survival data during the follow-up period revealed no significant difference. The study highlighted the need for a better preoperative risk stratification and the avoidance of lymphadenectomy for surgical staging alone.

Abstract
Cervical cancer is the fourth most common malignant tumor globally in terms of morbidity and mortality. The presence of lymph node metastasis (LNM) is an independent prognostic factor for progression-free survival (PFS) and overall survival (OS) in cervical cancer patients. The International Federation of Gynecology and Obstetrics (FIGO) staging system was revised in 2018. An important revision designates patients with regional LNM as stage IIIC, pelvic LNM only as stage IIIC1, and para-aortic LNM as stage IIIC2. However, the current staging system is only based on the anatomical location of metastatic lymph nodes (LNs). It does not consider other LN status parameters, which may limit its prognostic significance to a certain extent and needs further exploration and confirmation in the future. The purpose of this review is to summarize the choice of treatment for stage IIIC cervical cancer and the effect of different LN status parameters on prognosis.

Abstract
OBJECTIVE To evaluate patient-reported incidence and severity of early lymphedema and its impact on quality of life (QoL) after sentinel lymph node (SLN) mapping only and after SLN and pelvic lymphadenectomy (PL) in women undergoing surgery for early-stage cervical cancer. METHODS In a national prospective multicenter study, we included women with early-stage cervical cancer from March 2017-January 2021 to undergo radical surgery including SLN mapping. Women with tumors >20 mm underwent completion PL. The incidence and severity of early lymphedema and its influence on QoL were evaluated using validated patient-reported outcome measures before surgery and three months postoperative. We investigated changes over time using linear regression. RESULTS Two hundred of 245 (81.6%) included women completed questionnaires at baseline and three months postoperatively. The incidence of early lymphedema was 5.6% (95% CI 2.1-11.8%) and 32.3% (95% CI 22.9-42.7%) in women who underwent SLN mapping only and SLN + PL, respectively. Lymphedema symptoms in the legs, genitals, and groins increased in both groups postoperatively but three times more in women who underwent PL. Lymphedema symptoms after SLN + PL significantly impaired physical performance (p = 0.001) and appearance (p = 0.007). Reporting lymphedema was significantly associated with impaired body image, physical-, role-, and social functioning, and a high level of fatigue. CONCLUSIONS SLN mapping alone carries a low risk of lymphedema in women undergoing surgery for early-stage cervical cancer. In contrast, completion PL is associated with a high incidence of early lymphedema. Reporting lymphedema is associated with significant impairment of several physical, psychological, and social aspects of QoL.

Abstract
OBJECTIVE Lower limb lymphedema (LLL) is a common postoperative complication among gynecological oncology patients following lymph node resection. In the absence of a screening strategy, LLL is frequently diagnosed only through patient's self-reported symptoms. This study investigated the prevalence of undiagnosed postoperative LLL among gynecological oncology patients and identified the associated risk factors. MATERIALS AND METHODS This was a cross-sectional postal questionnaire survey at a tertiary gynecological oncology center. Women with gynecological malignancies who underwent lymph node (inguinal/pelvic/para-aortic) resection between 2010 and 2017 were eligible. The Gynecological Cancer Lymphedema Questionnaire (GCLQ) was used and those with a score of ≥4 were referred to a lymphedema specialist for clinical confirmation. RESULTS Among 376 eligible women, postoperative LLL was already diagnosed in 45/376 (12%) women. In the remaining women, 117/331 (35.3%) completed the GCLQ, of which 67/117 (57.3%) scored ≥4. Fifty-five women (55/67, 82.1%) were assessed by a lymphedema specialist and eight cases of postoperative LLL were confirmed. In the 12/67 who declined a clinical assessment, they reported no evidence of LLL. The prevalence of undiagnosed postoperative LLL in our study was 8/117 (6.8%, 95% C.I. 2.3-11.4). On univariate analysis, older women were more likely to have undiagnosed postoperative LLL. CONCLUSIONS Undiagnosed postoperative LLL is not uncommon among gynecological oncology patients, especially in older patients. No vulvar cancer patient had undiagnosed LLL. Increased awareness and improved strategies for lymphedema screening are required after lymph node surgery in gynecological oncology.

Abstract
Background Cervical cancer shows great differences in depth of invasion, metastasis, and other biological behaviors. The location of the lesion is special, so it is usually difficult to determine the clinical stage. This study aimed to explore the clinical value of magnetic resonance imaging (MRI) and tumor serum markers for the preoperative diagnosis of cervical cancer lymph node metastasis and para-uterine invasion. Methods A total of 200 patients with cervical cancer admitted to our hospital from January 2019 to January 2020 were collected as the research subjects. Comparing the diagnosis results of preoperative MRI scan, serum tumor markers, and postoperative pathological examination using single factor comparison, we determined the MRI scan results, the comprehensive matching rate between serum tumor markers (squamous cell carcinoma antigen (SCCA), carbohydrate antigen 125 (CA125)) and postoperative pathological results, and the differences of sensitivity, specificity, and accuracy in the prediction of lymph node metastasis and para-uterine infiltration of cervical cancer. Results The levels of SCCA and CA125 in patients with para-uterine invasion and lymph node metastasis were higher than those of patients without invasion and metastasis. Among them, the level of SCCA was significantly different (P<0.05). The level of CA125 was not statistically significant (P>0.05), so MRI combined with serum SCCA was selected for combined diagnosis in the later period. The sensitivity, specificity, and accuracy of MRI diagnosis of cervical cancer and para-uterine infiltrating lymph node metastasis and metastasis were 55.2, 91.6, and 89.5% and 55.2, 91.6, and 89.5%, respectively. These data in MRI combined with serum SCCA were 76.3, 95.3, and 94.3% and 63.2, 96.0, and 95.1%, respectively. The accuracy of tumor markers combined with MRI in the diagnosis of cervical cancer lymph node metastasis and para-uterine invasion was higher than that of MRI. Conclusions MRI combined with serum SCCA can more accurately identify cervical cancer lymph node metastasis and para-uterine invasion compared with MRI alone. Tumor marker combined with MRI diagnosis is an important auxiliary method for cervical cancer treatment and can provide comprehensive and reliable clinical evidence for evaluation before cervical cancer surgery.

Development of Surgical and Visualization Procedures to Analyze Vasculatures by Mouse Tail Edema Model. Biol Proced Online 2021; 23:21. [PMID: 34758723 PMCID: PMC8582144 DOI: 10.1186/s12575-021-00159-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Accepted: 10/26/2021] [Indexed: 12/02/2022] Open
Abstract
Background Because of the high frequency of chronic edema formation in the current “aged” society, analyses and detailed observation of post-surgical edema are getting more required. Post-surgical examination of the dynamic vasculature including L.V. (Lymphatic Vasculature) to monitor edema formation has not been efficiently performed. Hence, procedures for investigating such vasculature are essential. By inserting transparent sheet into the cutaneous layer of mouse tails as a novel surgery model (theTailEdema bySilicone sheet mediatedTransparency protocol; TEST), the novel procedures are introduced and analyzed by series of histological analyses including video-based L.V. observation and 3D histological reconstruction of vasculatures in mouse tails. Results The dynamic generation of post-surgical main and fine (neo) L.V. connective structure during the edematous recovery process was visualized by series of studies with a novel surgery model. Snapshot images taken from live binocular image recording for TEST samples suggested the presence of main and elongating fine (neo) L.V. structure. After the ligation of L.V., the enlargement of main L.V. was confirmed. In the case of light sheet fluorescence microscopy (LSFM) observation, such L.V. connections were also suggested by using transparent 3D samples. Finally, the generation of neo blood vessels particularly in the region adjacent to the silicone sheet and the operated boundary region was suggested in 3D reconstruction images. However, direct detection of elongating fine (neo) L.V. was not suitable for analysis by such LSFM and 3D reconstruction procedures. Thus, such methods utilizing fixed tissues are appropriate for general observation for the operated region including of L.V. Conclusions The current surgical procedures and analysis on the post-surgical status are the first case to observe vasculatures in vivo with a transparent sheet. Systematic analyses including the FITC-dextran mediated snap shot images observation suggest the elongation of fine (neo) lymphatic vasculature. Post-surgical analyses including LSFM and 3D histological structural reconstruction, are suitable to reveal the fixed structures of blood and lymphatic vessels formation.

Abstract
BACKGROUND Lower limb lymphoedema (LLL) is the most disabling adverse effect of surgical staging of pelvic lymph nodes. However, the lack of standardisation of volumetric LLL assessment hinders direct comparison between the studies and makes LLL reporting unreliable. The aim of our study is to report outcomes from a prospective trial that have implications for LLL assessment standardisation. METHODS In the prospective international multicentre trial SENTIX, a group of 150 patients with stage IA1-IB2 cervical cancer treated by uterine surgery with bilateral sentinel lymph node biopsy was prospectively evaluated by objective LLL assessment, based on limb volume change (LVC) using circumferrential limb measurements and subjective patient-reported swelling. The assessments were conducted in six-month periods over 24 months post-surgery. RESULTS Patient LVC substantially fluctuated in both positive and negative directions, which were comparable in frequency up to ±14% change. Thirty-eight patients experienced persistent LVC increase >10% classified as LLL, with nine months median time to onset. Some 34.2% of cases experienced onset later than one year after the surgery. Thirty-three patients (22%) experienced transient oedema characterised as LVC >10%, which resolved without intervention between two consequent follow-up visits. No significant correlation between LVC >10% and a patient-reported swelling was observed. CONCLUSIONS Given that we observed comparable fluctuations of the the lower-limb volumes after surgical treatment of cervical cancer in both positive and negative direction up to ±14%, the diagnostic threshold for LLL diagnosis based on LVC should be increased to >15% LVC. The distinction of transient oedema from persistent LLL requires repeated measurements. Also, as one-third of LLL cases are diagnosed >1-year post-surgery, a sufficient follow-up duration needs to be ensured. Patient-reported swelling correlated poorly with LVC and should only be used as an adjunct to objective LLL assessment. TRIAL REGISTRATION ClinicalTrials.gov: NCT02494063.

Creation of a rat lymphedema model using extensive lymph node dissection and circumferential soft tissue resection: Is this a reliable model? Microsurgery 2021; 41:762-771. [PMID: 34617323 DOI: 10.1002/micr.30817] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 09/14/2021] [Accepted: 09/20/2021] [Indexed: 12/24/2022]
Abstract
INTRODUCTION The medical demand for lymphedema treatment is huge since the disease mechanism remains unclear, and management are difficult. Our purpose was to develop a reliable lymphedema model mimicking the clinical scenario and allows a microsurgical approach. MATERIALS AND METHODS Male Lewis rats weighing 400 to 450 g were used to create lymphedema with groin and popliteal lymph node dissection and creation of 5 mm circumferential skin defect (n = 6). A skin incision was made and closed primarily for control group (n = 5). Evaluation included indocyanine green (ICG) lymphangiography 1 and 2 months postoperatively, volume difference between bilateral hindlimbs measured using micro-CT, and the skin was harvested for histological evaluation 2 months postoperatively. RESULTS Larger volume differences present in the lymphedema group (17.50 ± 7.76 vs. 3.73 ± 2.66%, p < .05). ICG lymphangiography indicated dermal backflow only in the lymphedema group. Increased thickness of the epidermis was noted in lymphedema group (28.50 ± 12.61 μm vs. 15.10 ± 5.41 μm, p < .0001). More CD45+ (35.6 ± 26.68 vs. 2.8 ± 4.23 cells/high power field [HPF], p < .0001), CD3+ (38.39 ± 20.17 vs. 9.73 ± 8.62 cells/HPF, p < .0001), and CD4+ cell infiltration (11.7 ± 7.71 vs. 2.0 ± 2.67 cells/HPF, p < .0001) were observed in the lymphedema group. Collagen type I deposition was more in the lymphedema group (0.15 ± 0.06 vs. 0.07 ± 0.03, p < .0005). CONCLUSIONS A rat lymphedema model was successfully established. The model can be applied in lymphedema related research.

J Vasc Surg Venous Lymphat Disord 2021; 10:728-737.e3.

Abstract
OBJECTIVE Indocyanine green (ICG) fluorescent lymphography might be useful for assessing patients undergoing lymphatic surgery for secondary lymphedema. The present clinical trial aimed to confirm whether ICG fluorescent lymphography would be useful in evaluating lymphedema, identifying lymphatic vessels suitable for anastomosis, and confirming patency of lymphaticovenular anastomosis in patients with secondary lymphedema. METHODS The present phase III, multicenter, single-arm, open-label, clinical trial (HAMAMATSU-ICG study) investigated the accuracy of lymphedema diagnosis via ICG fluorescent lymphography compared with lymphoscintigraphy, rate of identification of lymphatic vessels at the incision site, and efficacy for confirming patency of lymphaticovenular anastomosis. The external diameter of the identified lymphatic vessels and the distance from the skin surface to the lymphatic vessels using preoperative ICG fluorescent lymphography were measured intraoperatively under surgical microscopy. RESULTS When the clinical decision for surgery at each research site was made, the standard diagnosis of lymphedema was considered correct. For the 26 upper extremities, a central judgment committee who was unaware of the clinical presentation confirmed the imaging diagnosis was accurate for 100.0% of cases, whether the assessments had been performed via lymphoscintigraphy or ICG lymphography. In contrast, for the 88 lower extremities, the accuracy of the diagnosis compared with the diagnosis by the central judgment committee was 70.5% and 88.2% for lymphoscintigraphy and ICG lymphography, respectively. The external diameter of the identified lymphatic vessels was significantly greater in the lower extremities than in the upper extremities (0.54 ± 0.21 mm vs 0.42 ± 0.14 mm; P < .0001). Also, the distance from the skin surface to the lymphatic vessels was significantly longer in the lower extremities than in the upper extremities (5.8 ± 3.5 mm vs 4.4 ± 2.6 mm; P = .01). For 263 skin incisions, with the site placement determined using ICG fluorescent lymphography, the rate of identification of lymphatics vessels suitable for anastomosis was 97.7% (95% confidence interval, 95.1%-99.2%). A total of 267 lymphaticovenular anastomoses were performed. ICG fluorescent lymphography was judged as "useful" for confirming patency after the anastomosis in 95.1% of the cases. CONCLUSIONS ICG fluorescent lymphography could be useful for improving the treatment of patients with secondary lymphedema from the outpatient setting to surgery.

Ultrasound-guided fine needle aspiration cytology of Para-aortic lymph node metastasis in uterine cervical cancer: diagnostic accuracy and impact on clinical decision making. BMC Cancer 2021; 21:964. [PMID: 34452609 PMCID: PMC8393715 DOI: 10.1186/s12885-021-08492-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2021] [Accepted: 06/14/2021] [Indexed: 11/10/2022] Open
Abstract
OBJECTIVE The main aim of this study was to ascertain the effectiveness of ultrasound-guided fine needle aspiration cytology (US-FNAC) in the diagnosis of para-aortic lymph node (PALN) metastasis in uterine cervical cancer and to establish its potential impact on clinical therapeutic decision making. METHODS We retrospectively reviewed clinical data from 92 patients diagnosed with cervical cancer with PALN enlargement between 2010 and 2018. Cytological results obtained with US-FNAC were classified by the same experienced cellular pathologists. Diagnostic indicators were determined on the basis of biopsy, imaging and clinical follow-up results. Univariate and multivariate analyses were used to assess the differences of influencing factors. The effect of US-FNAC on clinical decision making was evaluated. RESULTS Cytological results of US-FNAC were categorized as malignancy (n = 62; 67.4%), suspicious malignancy (n = 11; 12.0%), undetermined (n = 5; 5.4%), benign (n = 10; 10.9%), and inadequate (n = 4; 4.3%). Satisfactory biopsy samples were obtained from 95.7% of PALNs sampled (88/92). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of FNAC in distinguishing benign from malignant cases were 90.1% (95% CI: 0.809-0.953), 100% (95% CI: 0.561-1), 100% (95% CI: 0.938-1), 46.7% (95% CI: 0.223-0.726) and 90.9% (95% CI: 0.848-0.970), respectively. Univariate analysis indicated significant differences in experience of puncture physicians (radiologists) between the correct and wrong diagnosis groups (P < 0.05), which was further confirmed as an independent predictor of diagnostic accuracy in multivariate analysis (p = 0.031, OR = 0.077, 95% CI: 0.354-0.919). All patients tolerated the US-FNAC procedure well and only nine presented slight abdominal discomfort. The therapeutic strategies for 74 patients (80.4%) were influenced by US-FNAC findings. CONCLUSIONS US-FNAC was a relatively safe and effective technique for examination of enlarged para-aortic lymph nodes and may therefore serve as a routine diagnostic tool to guide clinical decision making for management of cervical cancer.

Abstract
Background Cervical cancer is the second most common female malignant tumor in the world. According to a study in 2018, the incidence of cervical cancer in Yunnan Province of China was 11.42 per 100,000, the mortality rate was 3.77 per 100,000, and higher than the national average. Health-related quality of life (HRQoL) can be used not only in the selection and effect evaluation of clinical treatment plans of cervical cancer, but also in the evaluation of prognosis and long-term survival status. In this study, 288 cervical cancer patients admitted to the Yunnan Cancer Hospital in Southwest China from 2018 to 2020 were used as the survey objects to understand the HRQoL of cervical cancer patients and explore the related factors that affect HRQoL. Methods The Chinese version of the functional assessment of cancer therapy-cervix (functional assessment of cancer therapy-cervix v4.0, FACT-Cx V4) was used to investigate 288 patients with cervical cancer in Yunnan Province. Statistical analysis was performed using t-test, analysis of variance, multiple linear regression and other methods. Results The total FACT-Cx score of cervical cancer patients was (130.16 ± 14.20), the physical well-being (PWB) score was (22.02 ± 4.47), the social/family well-being (SWB) score was (25.66 ± 3.59), the emotional well-being (EWB) score was (19.75 ± 3.54), the functional well-being (FWB) score was (16.91 ± 5.01) and the additional focus area (cervical cancer subscale, CxS) score was (45.78 ± 4.61). From the multi-factor analysis results, the scores of PWB, FWB, Cxs and the total FACT-Cx were related to the choice of different treatment methods, the PWB scores of patients with concurrent chemoradiotherapy was low(β = − 1.67, P = 0.003), the FWB scores of patients with concurrent chemoradiotherapy was low(β = − 2.02, P = 0.001), the CxS scores of patients with concurrent chemoradiotherapy was low(β = − 1.61, P = 0.006), the total score of FACT-Cx of patients with concurrent chemoradiotherapy was low(β = − 5.91, P = 0.001). SWB score was affected by marital status, married patients had high PWB scores(β = 5.44, P = 0.006). The patients with heavy disease expenditures as aproportion of family disposable income(β = − 3.82, P = 0.002) and aged 60 and above(β = − 3.29, P = 0.003) had lower FWB scores. The total score FACT-Cx of patients participating in cervical cancer screening was higher(β = 7.61, P = 0.001). Conclusion The choice of treatment method is the common influencing factor of PWB, FWB, Cxs and the total FACT-Cx. Disease expenditures as a proportion of family disposable income, the treatment method, the marital status and whether to participate in cervical cancer screening affect the patient’s evaluation of their own HRQoL. Medical staff should pay special attention to the choice of different treatment methods, popularize vaccination knowledge and cervical cancer screening, give more humanistic care and health education to cervical cancer patients who have low education level, poor economic conditions, divorced or separated, and encourage patients to participate in active treatment to improve the health-related quality of life.

Abstract
Sentinel lymph node (SLN) biopsy has emerged as an alternative staging approach in women with assumed early-stage endometrial carcinoma. Through image-guided surgery and pathologic ultrastaging, the SLN approach is introducing “precision medicine” to the surgical management of gynecologic cancers, providing a comprehensive evaluation of high-yield lymph nodes. This approach improves the surgeons’ ability to detect small-volume metastatic disease while reducing intraoperative and postoperative morbidity associated with lymphadenectomy. Although the majority of clinicians in Europe and the USA have recognized the value of SLN biopsy in endometrial carcinoma and introduced this as part of clinical practice, there is ongoing debate regarding its role in very low-risk patients as well as in patients at high risk of nodal metastasis. The significance of low-volume metastasis is not fully understood, and there is no consensus in regard to how the presence of isolated tumor cells should guide adjuvant therapy. Standardized protocols for histopathologic evaluation of SLNs are lacking. In this review article we aim to provide a framework for the introduction of SLN biopsy in endometrial cancer, give an updated overview of the existing literature, as well as discuss potential controversies and unanswered questions regarding this approach and future directions.

Abstract
Background We aimed this investigation to screen and analyze the risk factors of postoperative lymphatic leakage of gynecological malignant tumors that contribute to the treatment of the diseases. Material/Methods According to the occurrence of lymphatic leakage after an operation, 655 patients with pelvic lymph node and/or abdominal para-aortic lymph node dissection for gynecological malignant tumor were retrospectively analyzed and divided into a case group and a control group. Univariate and multivariate logistic regression analysis were used to screen the effective independent risk factors and establish a clinical prediction model. The differentiation and calibration of the clinical prediction model were evaluated, and we performed internal and external validation of the model with 207 cases. Results The surgeons, the number of removed lymph nodes, the field and range of lymph nodes to be removed, the method of drainage, and postoperative infection are the independent risk factors of lymphatic leakage after lymph node dissection for gynecological malignant tumors. The area under the ROC curve of the clinical prediction model was 0.839 (P<0.001), the calibration Hosmer-Lemeshow test shows χ2=4.381, P=0.821. Through 10-fold cross-validation, the average correct rate of the prediction model was 0.899, the area under the ROC curve of the external verification group was 0.741, and the calibration Hosmer-Lemeshow test showed χ2=12.728, P=0.122. Conclusions The new logistic prediction model showed a good degree of differentiation and calibration in both the modeling and verification groups, and it can be used for early warning of the occurrence of lymphatic leakage after lymph node dissection.

Abstract
OBJECTIVES Sentinel lymph node (SLN) mapping may replace staging radical pelvic lymphadenectomy in women with early-stage cervical cancer. In a national multicenter setting, we evaluated SLN mapping in women with early-stage cervical cancer and investigated the accuracy of SLN mapping and FDG-PET/CT in tumors >20 mm. METHODS We prospectively included women with early-stage cervical cancer from March 2017-January 2021 to undergo SLN mapping. Women with tumors >20 mm underwent completion pelvic lymphadenectomy and removal of FDG-PET/CT positive nodes. We determined SLN detection rates, incidence of nodal disease, sensitivity and negative predictive value (NPV) of SLN mapping, and the sensitivity, specificity, NPV, and positive predictive value (PPV) of FDG-PET/CT. RESULTS We included 245 women, and 38 (15.5%) had nodal metastasis. The SLN detection rate was 96.3% (236/245), with 82.0% (201/245) bilateral detection. In a stratified analysis of 103 women with tumors >20 mm, 27 (26.2%) had nodal metastases. The sensitivity of SLN mapping adhering to the algorithm was 96.3% (95% CI 81.0-99.9%) and the NPV 98.7% (95% CI 93.0-100%). For FDG-PET/CT imaging the sensitivity was 14.8% (95% CI 4.2-33.7%), the specificity 85.5% (95% CI 75.6-92.5%), the NPV 73.9% (95% CI 63.4-82.7%), and the PPV 26.7% (95% CI 7.8-55.1%). CONCLUSIONS SLN mapping seems to be an adequate staging procedure in early-stage cervical cancer tumors ≤20 mm. In tumors >20 mm, SLN mapping is highly sensitive but demands full adherence to the SLN algorithm. We recommend completion pelvic lymphadenectomy in tumors >20 mm until the oncological safety is established. FDG-PET/CT for nodal staging of women with early-stage cervical cancer seems limited.

Sentinel lymph node biopsy and morbidity outcomes in early cervical cancer: Results of a multicentre randomised trial (SENTICOL-2). Eur J Cancer 2021; 148:307-315.

Abstract
INTRODUCTION Pelvic lymph node dissection has been the standard of care for patients with early cervical cancer. Sentinel node (SN) mapping is safe and feasible and may increase the detection of metastatic disease, but benefits of omitting pelvic lymph node dissection in terms of decreased morbidity have not been demonstrated. MATERIALS AND METHODS In an open-label study, patients with early cervical carcinoma (FIGO 2009 stage IA2 to IIA1) were randomly assigned to SN resection alone (SN arm) or SN and pelvic lymph node dissection (SN + PLND arm). SN resection was followed by radical surgery of the tumour (radical hysterectomy or radical trachelectomy). The primary end-point was morbidity related to the lymph node dissection; 3-year recurrence-free survival was a secondary end-point. RESULTS A total of 206 patients were eligible and randomly assigned to the SN arm (105 patients) or SN + PLND arm (101 patients). Most patients had stage IB1 lesion (87.4%). No false-negative case was observed in SN + PLND arm. Lymphatic morbidity was significantly lower in the SN arm (31.4%) than in the SN + PLND arm (51.5%; p = 0.0046), as was the rate of postoperative neurological symptoms (7.8% vs. 20.6%, p = 0.01, respectively). However, there was no significant difference in the proportion of patients with significant lymphoedema between the two groups. During the 6-month postoperative period, the difference in morbidity decreased over time. The 3-year recurrence-free survival was not significantly different (92.0% in SN arm and 94.4% in SN + PLND arm). CONCLUSION SN resection alone is associated with early decreased lymphatic morbidity when compared with SN + PLND in early cervical cancer.

Abstract
Objectives: We aimed to identify the risk factors associated with pelvic lymph node metastasis (LNM) at each anatomic location in patients with stage IB1 cervical cancer. Methods: A primary cohort of 728 patients with stage IB1 cervical cancer who underwent radical hysterectomy and systematic pelvic lymphadenectomy were retrospectively studied. All removed pelvic nodes (N=20,134) were pathologically examined. The risk factors for LNM in different anatomic regions (obturator, internal iliac, external iliac, and common iliac) were evaluated by multivariate logistic regression analyses. Nomograms were generated from the primary cohort and validated in another external cohort (N=242). The performance of the nomogram was assessed by its calibration and discrimination. Overall survival and progression-free survival in patients with different LNM patterns were compared. Results: LNM was found in 266 (1.3%) removed nodes and 106 (14.6%) patients. The incidences of LNM at the obturator, internal iliac, external iliac, common iliac, and parametrial regions were 8.5%, 5.4%, 4.7%, 1.9% and 1.8%, respectively. Among others, tumour size and lymph-vascular space invasion (LVSI), which are preoperatively assessable, were identified as independent risk factors of LNM in the common iliac region and the lower pelvis, respectively, and age was an additional independent risk factor of obturator LNM. The negative predictive values of tumour size <2 cm for common iliac LNM and negative LVSI combined with older age (> 50 years) for obturator LNM were 100% and 98.7%, respectively. A nomogram of these two factors showed good calibration and discrimination (concordance index, 0.761 in the primary cohort and 0.830 in validation cohort). The patients with common iliac LNM had poorer survival than those with LNM confined to the lower pelvis, while the differences in survival between patients with LNM confined to one node, one region or single side and those with more widely spreading LNM were not statistically significant. Conclusions: Tumour size, LVSI and age are region-specific risk factors for pelvic LNM in IB1 cervical cancer, which could be used to allocate the appropriate extent of pelvic lymphadenectomy.

Abstract
OBJECTIVE Lymph node (LN) metastasis is among the important prognostic factors for survival in endometrial cancer (EC). This study aimed to evaluate the occurrence of lymphatic complications following lymphadenectomy in patients with EC. MATERIALS AND METHODS EC patients were retrospectively evaluated. Lower extremity lymphedema (LEL) and pelvic lymphocele (PL) were evaluated according to the International Society of Lymphology guidelines and the National Cancer Institute Common Terminology Criteria for Adverse Events, respectively. RESULTS A total of 289 patients were enrolled. Surgery was performed via laparotomy and laparoscopy in 200 (69.2%) and 89 (30.8%) patients, respectively. LEL and PL occurred in 43 (14.9%) and 33 (11.4%) patients, respectively. In multivariate logistic regression analysis, circumflex iliac node (CIN) removal (odds ratio [OR]: 3.22; 95% CI: 1.43-7.98; P = 0.004) was an independent risk factor for LEL, while the surgical approach (OR: 4.46; 95% CI: 1.13-29.9; P = 0.004) was an independent risk factor for PL. CONCLUSION CIN dissection was a significant risk factor for LEL, while laparotomy was an independent risk factor for PL compared to laparoscopy in EC patients. This suggests that laparoscopic surgery combined with sentinel lymph node navigation surgery will prevent lymphatic complications in low-risk EC patients.

Abstract
OBJECTIVE To assess the cost-effectiveness of sentinel lymph node mapping compared to risk factor assessment and routine full lymph node dissection for the assessment of lymph nodes in patients with low- and intermediate-risk endometrioid endometrial cancer. METHODS A decision-analytic model was designed to compare three lymph node assessment strategies in terms of costs and effects: 1) sentinel lymph node mapping; 2) post-operative risk factor assessment (adjuvant therapy based on clinical and histological risk factors); 3) full lymph node dissection. Input data were derived from systematic literature searches and expert opinion. QALYs were used as measure of effectiveness. The model was built from a healthcare perspective and the impact of uncertainty was assessed with sensitivity analyses. RESULTS Base-case analysis showed that sentinel lymph node mapping was the most effective strategy for lymph node assessment in patients with low- and intermediate-risk endometrial cancer. Compared to risk factor assessment it was more costly, but the incremental cost effectiveness ratio stayed below a willingness-to-pay threshold of €20,000 with a maximum of €9637/QALY. Sentinel lymph node mapping was dominant compared to lymph node dissection since it was more effective and less costly. Sensitivity analyses showed that the outcome of the model was robust to changes in input values. With a willingness-to-pay threshold of €20,000 sentinel lymph node mapping remained cost-effective in at least 74.3% of the iterations. CONCLUSION Sentinel lymph node mapping is the most cost-effective strategy to guide the need for adjuvant therapy in patients with low and intermediate risk endometrioid endometrial cancer.

Abstract
BACKGROUND The aim of this study was to investigate the effect of maintaining opened distal lymphatic vessels of external iliac lymph nodes on lymphedema and lymphocyst formation of lower limbs after pelvic lymphadenectomy. METHODS Prospective single center observational study was carried out in 83 patients with gynecological malignancies who underwent pelvic lymphadenectomy. During the operation, the distal lymphatic vessels of the external iliac lymph nodes were cut off by an ultrasound scalpel or scissors, and the proximal end was closed by bipolar coagulation. The patients were re-examined by a physical examination, ultrasound examination and inquiry of the symptoms within 2 years after the operation to check whether they had lower limb lymphedema and to analyze the presence of lymphedema and lymphocyst of lower limbs and the risk. RESULTS The incidence of lower limb lymphedema (LLL) was 21.6% (18/83). Among the patients with LLL, 5.5% (1/18) was diagnosed with stage 0 according to the criteria of International Society of Lymphology, 83.3% (15/18) with stage 1, and 11.1% (2/18) with stage 2. Presently, there was no lymphedema diagnosed at stage 3. The incidence of lymphocyst was 7.2% (6/83). Among the patients with lymphocyst, 3.6% (3/83) occurred 1 month after operation, 2.4% (2/83) occurred 3 months after operation and 1.2% (1/83) occurred 6 months after operation. Patients with radiotherapy and abdominal infection were more likely to suffer from LLL (P<0.05). CONCLUSIONS Maintaining opened distal lymphatic vessels of external iliac lymph nodes during pelvic lymphadenectomy is feasible, safe and with a 21.6% and 7.2% of potential lymphedema and lymphocists, respectively.

Abstract
BACKGROUND Although microsurgical treatment for lower extremity lymphedema (LEL) can improve lower abdominal morphology, methods to evaluate the volume change of the lower abdomen have yet to be established. This study aimed to determine the accuracy and reproducibility of three-dimensional stereophotogrammetry (3DSM) in measuring the volume change in the lower abdomen. METHODS The perioperative volume changes in the lower abdomen were estimated using tape measurement (TM) and 3DSM in 26 patients with LEL. Thirteen patients with suprapubic lymphedema underwent abdominoplasty simultaneously. Each of them underwent multiple lymphaticovenular anastomoses (LVAs), and five of them underwent vascularized lymph node transfer, simultaneously. Thirteen patients with pelvic lymphatic fluid underwent multiple LVAs. Two patients underwent this surgery twice. When assessed on the Internal Society of Lymphology scale, eight patients were Stage I, 10 patients were Stage II, four patients were late Stage II, and four patients were Stage III. The difference between the two measurement methods and reproducibility of each method were analyzed. RESULTS During a mean follow-up period of 6 months, all patients had no postoperative complications and their chief complaint improved. The calculated reduction volume between TM and 3DSM showed a high correlation (p < .0001, r = .84). The reduction volume based on TM was significantly larger than 3DSM (991.1 ± 460.3 ml vs. 862.3 ± 333.5 ml, p = .02). The interrater ICC was 0.94 and 0.98 based on TM and 3DSM, respectively. CONCLUSION 3DSM may be a useful method for assessment of the lower abdominal morphology due to its high accuracy and reproducibility.

Abstract
AIM To clarify the incidence of lymphatic drainage disorders (LLD) after treatment for cervical cancer (CC) and to establish univariate models for their occurrence. METHODS A total of 263 eligible patients with CC were identified between 2010 and 2019. We conducted a case-control study and divided the study population into two subsamples of 12 and 251 CC survivors based on the presence/absence of LLD, respectively. The cumulative incidence was evaluated using the Kaplan-Meier method. Univariate models based on Pearson correlation coefficient were used to evaluate associations between explanatory variables and LLD. RESULTS The cumulative incidence of LLD began at 3.3% after the 7-month follow-up, reaching a plateau of 21.2% between 130 and 250 months of follow-up. We detected correlation between LLD and number of removed para-aortic lymph nodes (r = -0.39), number of pelvic lymphadenopathies (r = 0.16), pelvic lymphadenectomy (PL) (r = 0.16), age at diagnosis of CC (r = -0.1) and primary surgery (r = 0.1). CONCLUSION We observed a cumulative incidence of LLD of 21.2%, which is in accord with other retrospective studies. Number of removed para-aortic lymph nodes, number of pelvic lymphadenopathies, PL, age at diagnosis of CC and primary surgery were the most influential clinical factors associated with the occurrence of LLD in CC survivors.

Abstract
OBJECTIVE Due to the growing evidence of sentinel lymph node (SLN) mapping in endometrial cancer (EC), our aim was to evaluate the impact of SLN mapping and other clinical-pathological variables in the risk of developing lymphocele. METHODS We retrospectively analyzed a series of patients with ECs who underwent lymph node staging with SLN mapping with or without systematic pelvic ± para-aortic lymphadenectomy from November 2012 to January 2020. The lymphocele diagnosis was performed by computed tomography or magnetic resonance imaging. RESULTS Of 348 patients included, 178 underwent SLN mapping only and 170 underwent SLN mapping and systematic lymphadenectomy (46.5% pelvic only; 53.5% pelvic and para-aortic). Seventy-three (21%) patients had open surgery and 275 (79%) had a minimally invasive approach. After a median follow-up of 25.4 months, the overall prevalence of lymphocele was 8.6% (n = 30), with 29 cases in a pelvic location. Lymphocele was found in 3.4% (n = 6/178) of patients submitted to SLN mapping only, compared with 14.1% (n = 24/170) among those who underwent SLN with lymphadenectomy (p = 0.009). Among those patients with lymphocele, seven (23.3%) were symptomatic and five (16.6%) required drainage. All symptomatic cases occurred in lymphoceles larger than 4 cm (p = 0.001). Neither resected lymph node count nor the type of systematic lymphadenectomy were related to the presence of lymphocele. Systematic lymphadenectomy was the only factor that emerged as a risk factor for the presence of lymphocele in multivariate analysis (odds ratio 3.68, 95% confidence interval 1.39-9.79; p = 0.009). CONCLUSIONS Our data suggest that SLN mapping independently decreases the risk of lymphocele formation compared with full lymphadenectomy in EC.

Comparison of different lymph node staging systems in patients with node-positive cervical squamous cell carcinoma following radical surgery. J Cancer 2020; 11:7339-7347. [PMID: 33193898 PMCID: PMC7646177 DOI: 10.7150/jca.48085] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Accepted: 10/12/2020] [Indexed: 01/02/2023] Open
Abstract
Objective: We compared the prognostic accuracy of four lymph node (LN) staging systems - the 2018 International Federation of Gynecology and Obstetrics (FIGO) stage, number of positive lymph node (PLN), metastatic lymph node ratio (LNR), and log odds of positive lymph nodes (LODDS) systems - in patients with node-positive cervical squamous cell carcinoma (CSCC) following radical surgery and explored the optimal choice for clinical applications. Materials and methods: Data were retrospectively collected from 928 node-positive CSCC patients who underwent radical surgery between 2006 and 2014 in our center. Tree-based recursive partitioning was applied to split variables (PLN, LNR, and LODDS) into low-risk and high-risk groups. The log-rank test was used to compare survival curves, and Cox regression analysis was performed to identify prognostic factors. The relative discriminative abilities of the different staging systems were assessed using Harrell's concordance index (C index) and the Akaike information criterion (AIC). Results: The mean number of PLNs was 3.8 (range: 1-44 nodes). According to the 2018 FIGO staging system, 831 patients had stage IIIC1, and 97 had stage IIIC2. For the PLN system, 761 patients were included in the low-risk group, and 167 were included in the high-risk group. For the LNR system, 658 patients were included in the low-risk group, and 270 were included in the high-risk group. The low-risk LODDS group included 694 patients, while the high-risk LODDS group included 234 patients. All four staging systems had a significant influence on patients' progression-free survival (PFS, P < 0.001) and overall survival (OS, P < 0.001). Univariate analysis and multivariate Cox analysis adjusted for significant factors indicated that the four staging systems were significant prognostic factors for PFS and OS. Among them, the PLN system was noted to have the best prognostic performance for both PFS (C index: 0.582; AIC: 8213.33) and OS (C index: 0.624; AIC: 8433.80). Conclusion: The PLN system seemed to be the most accurate LN staging method for predicting node-positive CSCC following radical surgery.

Comparison of Postoperative Benign Pelvic Cysts Occurred after Gynecologic or Gyne-oncologic Surgery Treated with Percutaneous Transcatheteric Sclerosant Alcohol Therapy. Gynecol Minim Invasive Ther 2020; 9:198-203.

Abstract
Objectives: Here, we compare the success of percutaneous transcatheter sclerosant alcohol therapy (PTSAT) for the postoperative treatment of benign pelvic cysts that occurred after gynecologic surgery. Materials and Methods: The study is a retrospective case–control trial. Gynecological patients who had symptoms due to postoperative pelvic cysts and received PTSAT after gynecologic surgery, between October 2008 and January 2018, were examined in a single training and research hospital in Turkey. Some factors were investigated for associations with postoperative pelvic cyst formation in patients who underwent gynecologic operations for malignancies or benign conditions. Statistical analysis used: The association between two independent and nonnormally distributed continuous variables was analyzed with the Mann–Whitney U-test. Spearman's rho correlation analysis was conducted to determine the correlation of two nonnormally distributed variables. Chi-square (or Fisher's exact test, when more suitable) was used to examine the correlation between categorical variables. Results: Statistically significant differences were found in terms of the average age was higher in patients with malignancies, and the average postoperative pelvic cyst detection time was higher in patients with benign pelvic cysts. While all patients were treated with PTSAT, repetitive PTSAT was required for seven benign and ten malign cases. Conclusion: Patients with pelvic cysts that occurred after gynecologic surgery for malignant conditions, large volume pelvic cysts and patients with benign cysts who underwent more than one surgery required recurrent PTSAT.

Influence of 99m-Tc-Nanocolloid Activity Concentration on Sentinel Lymph Node Detection in Endometrial Cancer: A Quantitative SPECT/CT Study. Diagnostics (Basel) 2020; 10:diagnostics10090700. [PMID: 32947918 PMCID: PMC7555748 DOI: 10.3390/diagnostics10090700] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Revised: 09/14/2020] [Accepted: 09/15/2020] [Indexed: 12/13/2022] Open
Abstract
This study evaluates quantitative combined single photon emission tomography/computed x-ray tomography (SPECT/CT) to assess the influence of radiotracer concentration on detection of sentinel lymph nodes (SLN) in endometrial cancer (EC). Eighty EC patients underwent pericervical 99m-Tc-nanocolloid injection followed by SPECT/CT. The subgroup of patients with failed SLN detection in SPECT/CT (n = 20) was compared to match-paired patients showing at least two SLNs. Results of intraoperative gamma probe measurements and quantitative SPECT/CT were used for comparison. In patients with detection failure, the percentage of injected dose, absolute activity, and volume of the injection site were significantly lower (30 ± 24% vs. 55 ± 19%; p = 0.01, 43 ± 36 MBq vs. 73 ± 33 MBq; p = 0.04, and 183 ± 164 mL vs. 266 ± 164 mL; p = 0.03) while mean activity concentration in liver, spleen, and bone marrow was significantly higher (p = 0.02). Activity concentration (>33 KBq/mL) and absolute activity (>73 MBq) of injection areas correlated with successful intraoperative SLN detection. In a subgroup of 19 SLNs, a correlation between SPECT/CT-derived uptake and intraoperative count rate was found (R2 = 0.8; p < 0.001). SLN detection in EC patients depended on high radiotracer activity at the cervical injection site. Quantitative SPECT/CT could predict successful intraoperative SLN detection and may help to optimize injection technique.
