Feasibility and Safety of Video Endoscopic Inguinal Lymphadenectomy in Vulvar Cancer: A Systematic Review.

ABSTRACT: OBJECTIVE:To systematically review previous studies and to evaluate the feasibility and safety of video endoscopic inguinal lymphadenectomy (VEIL) in vulvar cancer. METHODS:We conducted a comprehensive review of studies published through September 2014 to retrieve all relevant articles. The PubMed, EMBASE, Web of Science, Cochrane Library, Wan Fang Data and Chinese National Knowledge Infrastructure databases were systematically searched for all relevant studies published in English or Chinese through September 2014. Data were abstracted independently by two reviewers, and any differences were resolved by consensus. RESULTS:A total of 9 studies containing 249 VEIL procedures involving 138 patients were reviewed. Of the 249 VEIL procedures, only 1 (0.4%) was converted to an open procedure for suturing because of injury to the femoral vein. The range of operative time was 62 to 110 minutes, and the range of estimated blood loss was 5.5 to 22 ml. The range of the number of harvested lymph nodes was 7.3 to 16. The length of hospital stay varied from 7 to 13.6 days across reports. The incidence of lymph node metastasis was 19.7% (27/138), and the recurrence rate was 4.3% (3/70) within 3 to 41 months of follow-up. One or more short-term complications were documented in 18 of 138 (13.0%) patients. Complications after VEIL were observed in 14 (10.13%) patients and in 15 (6.0%) of the VEIL cases, including major lymphocyst formation in 9 (3.6%), lymphorrhea in 2 (0.8%), inguinal wound infection without wound breakdown in 3 (1.2%) and lymphedema in 1 (0.4%). CONCLUSIONS:VEIL appears to be a feasible procedure in the management of vulvar cancer. There may be potential benefits that result in lower morbidity compared to traditional methods, but this has yet to be objectively proven.

Project description:Accurate mediastinal lymph node dissection during thoracotomy is mandatory for staging and for adjuvant therapy in lung cancer. Pre-therapeutic staging for neoadjuvant therapy or for video assisted thoracoscopic resection of lung cancer is achieved usually by CT-scan and mediastinoscopy. However, these methods do not reach the accuracy of open nodal dissection. Therefore we developed a technique of radical video-assisted mediastinoscopic lymphadenectomy (VAMLA). This study was designed to show that VAMLA is feasible and that radicality of lymphadenectomy is comparable to the open procedure.In a prospective study all VAMLA procedures were registered and followed up in a database. Specimens of VAMLA were analysed by a single pathologist. Lymph nodes were counted and compared to open lymphadenectomy. The weight of the dissected tissue was documented. In patients receiving tumour resection subsequently to VAMLA, radicality of the previous mediastinoscopic dissection was controlled during thoracotomy.37 patients underwent video-assisted mediastinoscopy from June 1999 to April 2000. Mean duration of anaesthesia was 84.6 (SD 35.8) minutes.In 7 patients radical lymphadenectomy was not intended because of bulky nodal disease or benign disease. The remaining 30 patients underwent complete systematic nodal dissection as VAMLA.18 patients received tumour resection subsequently (12 right- and 6 left-sided thoracotomies). These thoracotomies allowed open re-dissection of 12 paratracheal regions, 10 of which were found free of lymphatic tissue. In two patients, 1 and 2 left over paratracheal nodes were counted respectively. 10/18 re-dissected subcarinal regions were found to be radically dissected by VAMLA. In 6 patients one single node and in the remaining 2 cases 5 and 8 nodes were found, respectively. However these counts also included nodes from the ipsilateral main bronchus. None of these nodes was positive for tumour.Average weight of the tissue that was harvested by VAMLA was 10.1 g (2.2-23.7, SD 6.3). An average number of 20.5 (6-60, SD 12.5) nodes per patient were counted in the specimens. This is comparable to our historical data from open lymphadenectomy.One palsy of the recurrent nerve in a patient with extensive preparation of the nerve and resection of 11 left-sided enlarged nodes was the only severe complication in this series.VAMLA seems to accomplish mediastinal nodal dissection comparable to open lymphadenectomy and supports video assisted surgery for lung cancer. In neoadjuvant setting a correct mediastinal N-staging is achieved.

Project description:Simple Summary Currently, around 30% of vulvar cancer cases at first diagnosis are spread to the inguinal lymph nodes. Preoperative staging of patients affected by vulvar carcinoma is still a hot topic. To date, MRI has shown a great diagnostic accuracy on defining disease extension to soft tissue and deep organs. At present, regarding the study of inguinal nodes, the PET/CT scan has shown a high negative predictive value, although in the presence of a suspicious/positive report it should be taken with caution. We report the results of a study aimed to investigate the role of groin ultrasound in the assessment of lymph nodal status in vulvar cancer. Furthermore, this review represents the most accurate collection of papers available in the literature. This work demonstrates that groin ultrasound can be considered a valuable tool for risk assessment of the presence of groin lymph node metastases. Achieving a high diagnostic accuracy would allow tailored surgical planning with access to minimally invasive surgery techniques for an increasing number of patients. Abstract Objective. To determine the efficacy of ultrasound in assessing the inguinal lymph nodes in patients with vulvar cancer. Methods. A systematic review of published research up to October 2020 that compares the results of ultrasound to determine groin node status with histology was conducted. All study types that reported primary data on the role of ultrasound in the evaluation of groin lymph nodes in vulvar cancer were included in the systematic review. Data retrieved from the included studies were pooled in random-effects meta-analyses. Results. After the screening and selection process, eight articles were deemed pertinent for inclusion in the systematic review and meta-analysis. The random-effects model showed a pooled Se of 0.85 (95% CI: 0.81–0.89), Sp of 0.86 (95% CI: 0.81–0.91), PPV of 0.65 (95% CI: 0.54–0.79) and NPV of 0.92 (95% CI: 0.91–0.94). There was a pooled LR+ and LR− of 6.44 (95% CI: 3.72–11.4) and 0.20 (95% CI: 0.14–0.27), respectively. The pooled accuracy was 0.85 (95% CI: 0.80–0.91). Conclusions. Although the studies had small sample sizes, this review represents the best summary of the data so far. Ultrasound has revealed high sensitivity and high negative predictive value in the assessment of nodal status in vulvar cancer.

Project description:OBJECTIVE:The current study was prospectively designed to explore the application of video-assisted thoracoscopic surgery (VATS) radical treatment for patients with stage IIIA lung cancer, with the primary endpoints being the safety and feasibility of this operation and the second endpoints being the survival and complications after the surgery. METHODS:A total of 51 patients with radiologically or mediastinoscopically confirmed stage IIIA lung cancer underwent VATS radical treatment, during which the standard pulmonary lobectomy and mediastinal lymph node dissection were performed after pre-operative assessment. The operative time, intraoperative blood loss/complications, postoperative recovery, postoperative complications, and lymph node dissection were recorded and analyzed. This study was regarded as successful if the surgical success rate reached 90% or higher. RESULTS:A total of 51 patients with non-small cell lung cancer (NSCLC) were enrolled in this study from March 2009 to February 2010. The median post-operative follow-up duration was 50.5 months. Of these 51 patients, 41 (80.4%) had N2 lymph node metastases. All patients underwent the thoracoscopic surgeries, among whom 50 (98%) received pulmonary lobectomy and mediastinal lymph node dissection completely under the thoracoscope, 6 had their incisions extended to about 6 cm due to larger tumor sizes, and 1 had his surgery performed using a 12 cm small incision for handling the adhesions between lymph nodes and blood vessels. No patient was converted to conventional open thoracotomy. No perioperative death was noted. One patient received a second surgery on the second post-operative day due to large drainage (>1,000 mL), and the postoperative recovery was satisfactory. Up to 45 patients (88.2%) did not suffer from any perioperative complication, and 6 (11.8%) experienced one or more complications. CONCLUSIONS:VATS radical treatment is a safe and feasible treatment for stage IIIA lung cancer.
