RESUMEN
OBJECTIVE: The oncological outcome regarding disease-free survival and overall survival after radical vaginal trachelectomy (RVT) is the same as the rates after radical hysterectomy. We aim to analyze predictive and risk factors and death in patients with cervical cancer undergoing fertility preservation by laparoscopic lymphadenectomy and RVT. METHODS: Three hundred twenty patients with cervical cancer underwent RVT between March 1995 and February 2013. In our study, we examined recurrence rates analyzed by risk factors. We classified the presence of lymphovascular space invasion, depth of tumor infiltration, tumor size, and tumor grading as risk factors. The mean follow-up time was 48 months. RESULTS: Ten of the 320 patients had cancer recurrence. Recurrence appeared at a mean time of 26.1 months (3-108 months) after RVT. Five patients died within 8.8 months (4-15 months) after recurrence was diagnosed. Two of these 5 patients had distant metastasis at the time of recurrence. Five patients were treated successfully by surgery, and 4 patients were treated successfully by chemotherapy. The mean follow-up after the recurrence of these 5 patients is 76 months (6-120 months). None of the 10 patients with recurrences in our series showed significant high-risk factors. CONCLUSION: There seems to be no pattern in the recurrence of cancer after RVT. It is strictly mandatory to follow up the patients closely every 3 months after RVT to diagnose recurrence at an early stage so therapeutic options such as chemoradiation are still available. Once distant metastasis occurs, prognosis is not good.

PURPOSE: To determine the rate of unavoidable adjuvant chemoradiation (RCTX) due to histologic results after radical surgery in patients with early cervical cancer. PATIENTS AND METHODS: Between May 2004 and July 2011, 448 consecutive patients diagnosed with invasive cervical cancer stage IA1 L1 to IIA underwent laparoscopic staging at the Department of Gynecology and Gynecologic Oncology at Charité Berlin. Only in patients without lymph node metastases (n = 394) on frozen section, radical operation was continued either by laparoscopic radical hysterectomy (n = 228) or by radical vaginal trachelectomy (n = 166). The decision for adjuvant RCTX was reached among the members of an interdisciplinary tumor board according to the presence of risk factors. The mean age of patients was 39 years. Squamous cell cancer was found in 62.5%, adenocarcinoma in 32.7%, adenosquamous cancer in 3.8% and others in 1% of patients. Adjuvant treatment was indicated if at least one category 1 risk factor (pN1, R1 or RX, parametrial involvement) and/or any combination of category 2 risk factors (lymphovascular space involvement (LVSI), hemovascular space involvement, grading 3, young age, deep stromal invasion, large tumor size) were present. RESULTS: In 39 of 394 patients (9.9%), adjuvant RCTX was recommended due to category 1 risk factors (n = 25/6.4%) and category 2 risk factors (n = 14/3.5%). Tumor-involved (R0) or unclear resection margins (RX) were present in 4 (1%) and 1 (0.3%), parametrial involvement in 12 (3%) and positive lymph nodes in 11 (2.8%) patients, respectively. Hemovascular involvement was found in 14 (3.5%), LVSI in 113 (28.7%) and grading 3 in 122 (31%) patients, respectively. CONCLUSION: Laparoscopic staging is a reliable tool to keep the rate of tri-modal (surgery + chemotherapy + radiotherapy) treatments in patients with cervical cancer stage I and IIA after radical surgery at 10%. This percentage should be used as benchmark for the quality of interdisciplinary treatment of patients diagnosed with cervical cancer.

PURPOSE: To proof feasibility of hydrogel application in patients with advanced cervical cancer undergoing chemo-radiation in order to reduce rectal toxicity from external beam radiation as well as brachytherapy. MATERIAL AND METHODS: Under transrectal sonographic guidance five patients with proven cervical cancer underwent hydro gel (20 cc) instillation into the tip of rectovaginal septum adherent to posterior part of the visible cervical tumor. Five days after this procedure all patients underwent T2 weighted transversal and sagittal MRI for brachytherapy planning. MRI protocol included T2 weighted fast spin echo (FSE) imaging in sagittal, coronal and para-axial orientation using an 1.5 Tesla MRI. Separation of anterior rectal wall and cervix was documented. RESULTS: Hydrogel application was uneventful in all patients and no toxicity was reported. Separation ranged from 7 to 26 mm in width (median 10 mm). The length of the separation varied between 18 and 38 mm (median 32 mm). In all patients displacement was seen in the posterior vaginal fornix, and/or at the deepest part of uterine cervix depending on the extension of the cul-de-sac in correlation to the posterior wall of the uterus. In patients with bulky tumor and/or deep (vaginal) extend of peritoneal cavity tumour was seen mainly cranial from the rectovaginal space and therefore above the hydrogeI application. Only in the extra-peritoneal (lower) part of the cervix a good separation could be achieved between the rectum and cervix. CONCLUSION: Hydrgel instillation in patients with cervial cancer undergoing chemoradiation is safe and feasible. Because of the loose tissue of the cul-de-sac and its intra- and extraperitoneal part, hydrogel instillation of 20 cc did not result in a sufficient separation of the cervix from anterior wall.

To investigate the role of the nerve growth factor (NGF) in the endometriosis-associated innervation in the development of endometriosis-associated symptoms, 41 peritoneal fluid samples (PF) from patients with surgically and histologically proven endometriosis and 20 PF from patients with other gynecologic conditions were analyzed with Western blot and a novel in vitro model using dorsal root ganglia (DRG) to show neuronal outgrowth; endometrial cells also were analyzed. The results suggest that the PF of endometriosis patients and endometriotic lesions have neurotropic properties, because the Western blot analysis and the cell culture stainings showed NGF expression, and the neurite outgrowth of DRG treated with PF of patients with endometriosis was significantly higher than when treated with PF of patients without endometriosis. Furthermore, blocking NGF with both anti-NGF and K252a leads to a significant decrease in neurite outgrowth.

OBJECTIVE: Axis and support of the vagina can be restored by sacrocolporectopexy with preservation of coital function. We developed a new technique of transvaginal sacrocolporectopexy for patients with prolapse of uterus and vagina or prolapse of the vaginal vault. STUDY DESIGN: During a 4-year period, 20 patients with vaginal vault prolapse and 83 patients with uterine and vaginal prolapse underwent transvaginal sacrocolporectopexy. Intra- and postoperative complications were recorded. After a mean follow-up period of 24 months (6-48), the result of surgery with respect to prolapse, incontinence, and sexuality was evaluated by patient interviews. RESULTS: No serious perioperative complications occurred with the exception of one patient with bleeding from a presacral vein. Subjectively, 84 patients (82%) were cured of prolapse symptoms. One patient had recurrent grade II vault prolapse and four patients developed a grade II rectocele. Five patients developed urge incontinence grade I. One patient developed fecal incontinence. No patient had coital problems as a sequelae of sacrocolporectopexy. CONCLUSION: Transvaginal sacrocolporectopexy is a safe procedure with a success rate comparable to sacrospinous fixation.
