Risk for Pelvic Metastasis and Role of Pelvic Lymphadenectomy in Node-Positive Vulvar Cancer-Results from the AGO-VOP.2 QS Vulva Study

The need for pelvic treatment in patients with node-positive vulvar cancer (VSCC) and the value of pelvic lymphadenectomy (LAE) as a staging procedure to plan adjuvant radiotherapy (RT) is controversial. In this retrospective, multicenter analysis, 306 patients with primary node-positive VSCC treated at 33 gynecologic oncology centers in Germany between 2017 and 2019 were analyzed. All patients received surgical staging of the groins; nodal status was as follows: 23.9% (73/306) pN1a, 23.5% (72/306) pN1b, 20.4% (62/306) pN2a/b, and 31.9% (97/306) pN2c/pN3. A total of 35.6% (109/306) received pelvic LAE; pelvic nodal involvement was observed in 18.5%. None of the patients with nodal status pN1a or pN1b and pelvic LAE showed pelvic nodal involvement. Taking only patients with nodal status ≥pN2a into account, the rate of pelvic involvement was 25%. In total, adjuvant RT was applied in 64.4% (197/306). Only half of the pelvic node-positive (N+) patients received adjuvant RT to the pelvis (50%, 10/20 patients); 41.9% (122/291 patients) experienced recurrent disease or died. In patients with histologically-confirmed pelvic metastases after LAE, distant recurrences were most frequently observed (7/20 recurrences). Conclusions: A relevant risk regarding pelvic nodal involvement was observed from nodal status pN2a and higher. Our data support the omission of pelvic treatment in patients with nodal status pN1a and pN1b.

ABSTRACT OUTCOMES OF INVASIVE BLADDER CANCER TREATED BY PROSTATE SPARING RADICAL CYSTECTOMY WITH EXTENDED PELVIC LYMPHADENECTOMY AND ORTHOTOPIC ILEAL NEOBLADDER Background: Radical cystectomy is considered a “gold standard” procedure to treat invasive bladder cancer. Orthotopic ileal neobladder after cystectomy as well as lymphadenectomy, which avoids metastasis and enhances postoperative 5 - years survival rate are important. Moreover, the quality of life after this kind of surgery is a great concern. Purpose: Evaluating results of treatment of invasive bladder cancer by prostate sparing radical cystectomy with extended pelvic lymphadenectomy and orthotopic ileal neobladder. Material and Method: Prospective and descriptive clinical study without a control group in 43 males who were diagnosed with invasive bladder cancer (cT2a - T4aN0M0), they underwent prostate sparing radical cystectomy with extended pelvic lymphadenectomy and orthotopic ileal neobladder, from 1/2015 to12/2020 at Department of General Surgery, Hue Central Hospital. Results: The operative time: 213,5 ± 29,7 min. The estimated blood loss: 130 ± 90 ml. The mean number of lympho nodes which is conducted lymphadenectomy: 11,5 ± 4,5. The length of hospital stay: 17,12 ± 6,45 days. Early complication rate: 32,6%. The majority of patients who were discharged from the hospital passed urine with urinary incontinence, weak urine stream and voided volume < 150ml. The volume of the neobladder increased with statistical significance through follow - up examinations (p < 0,05). The daytime continence rate was 97,2% after 6 months. 1/43 case recured at cystourethral anastomosis after 4 months. 7 cases dead due to cancer progression. Conclusion: Prostate sparing radical cystectomy with extended pelvic lymphadenectomy and Hautmann - Studer orthotopic ileal neobladderstill thoroughly solve oncologic issues, reduce the possibility of lymph node metastasis recurrence. The patient still has the sexual ability and urinary continence after this procedure. Keywords: Extended pelvis lymphadenectomy; invasive bladder cancer; radical cystectomy; orthotopic ileal neobladder.

Radical Vaginal Trachelectomy

Recently, radical vaginal hysterectomy (RVH) has developed into laparoscopically assisted radical vaginal hysterectomy (LARVH), which is associated with the laparoscopical procedure, and it is applied as radical vaginal trachelectomy and semi-radical vaginal hysterectomy. LARVH is indicated for patients with stage IB1 and IIA1 cervical carcinoma, especially those with a tumor size of less than 2 cm, because the cardinal ligaments cannot be resected widely. Although RVH that is associated with laparoscopic pelvic lymphadenectomy is the most used surgical procedure, radical trachelectomy may be performed either abdominally or vaginally (laparoscopic or robotic). One report found that the pregnancy rate was higher in patients who underwent minimally invasive or radical vaginal trachelectomy than in those who underwent radical abdominal trachelectomy.

Nerve-Sparing Radical Hysterectomy Using the Okabayashi–Kobayashi Method

Radical hysterectomy (RH) is a standard treatment for early-stage cervical cancer. This surgery extirpates the uterus along with the paracervical tissues, vagina, and the paracolpium to achieve local control. Pelvic lymphadenectomy is a critical component of RH performed for regional control. A clear understanding of pelvic anatomy is critical to safely performing a RH and achieving optimal oncological and functional outcomes. The various surgical steps can damage the pelvic autonomic nerves, and a systematic nerve-sparing technique is used for the preservation of autonomic nerves. There is an intricate vascular network in the lateral paracervix (cardinal ligament) and the pelvic sidewall. We need to comprehend the three-dimensional structure of the vascular and nerve anatomy in the pelvis to perform RH effectively and safely. We can create six spaces around the uterine cervix, including the paravesical spaces, pararectal spaces, a vesicovaginal space, and a rectovaginal space to reveal the target of extirpation. It is critical to find the proper tissue plane separated by the layers of membranous connective tissue (fascia), in order to minimize intraoperative bleeding.

Risk Factors of Pelvic Lymph Node Metastasis and Recurrence in Patients with Early Cervical Cancer

Background: Pelvic lymph node metastasis (PLNM) is one of the critical factors affecting the postoperative prognosis of patients with cervical cancer. Preoperative identification of risk factors for PLNM can optimize preoperative treatment plans and prognostic assessments.The purpose of this study was to investigate the risk factors for PLNM and its recurrence in patients undergoing radical hysterectomy for cervical cancer.Methods: Medical records of 245 patients who underwent radical hysterectomy and bilateral pelvic lymphadenectomy as primary treatment for the International Federation of Gynaecology and Obstetrics (FIGO,2009) stage IA-IIA cervical cancer between January 2010 and December 2015 were reviewed. Clinicopathological risk factors were retrospectively analyzed. All patients were followed up for 5–10 years. Multivariate analysis was performed using a logistic regression model for the analysis of risk factors for PLNM.Results: Preoperative hemoglobin level, FIGO stage, LVSI, parametrial infiltration, and tumor diameter differed significantly between the two groups (P<0.05).Multivariate analysis revealed preoperative hemoglobin <110 g/L, FIGO stage II, LVSI, parametrial infiltration, and tumor diameter ≥4 cm as significant risk factors for PLNM and recurrence of cervical cancer after surgery (P<0.05). PLNM was identified as the independent risk factor for recurrence in patients with cervical cancer after surgery (P<0.05).Conclusions: Patients with PLNM have a high recurrence rate, and postoperative follow-up should be closely followed to ensure timely detection of recurrence and treatment. For patients at high risk of PLNM, intraoperative careful and comprehensive pelvic lymph node resection should be performed to avoid missing metastatic lymph nodes and affecting the prognosis. Given the many complications of pelvic lymph node dissection for the low-risk population, further research is needed to determine whether pelvic lymphadenectomy should be attempted only in high-risk individuals.

Lymphatic leakage after pelvic lymphadenectomy for cervical cancer: a retrospective case-control study

Background The study aims to evaluate the clinical features and management of postoperative lymphatic leakage (PLL) in patients with cervical cancer who received pelvic lymphadenectomy. Methods This retrospective study screened consecutive patients with cervical cancer (stage Ia2-IIb). Results Among 3427 cases screened, 63 patients (1.8%) were diagnosed with PLL, which manifested as persistent abdominal drainage (42/63, 66.7%), chylous ascites (12/63, 19.0%) or vaginal drainage (9/63, 14.3%). Median time from surgery to onset of PLL was 6 days (range, 4–21 days). All cases resolved in a median 10 days (range, 3–56 days) after conservative treatment; although one case experienced recurrence of vaginal drainage after 26 days, this also resolved after conservative therapy. Multivariate analysis showed that two cycles of neoadjuvant chemotherapy (odds ratio [OR], 3.283; 95% confidence interval [95%CI], 1.289–8.360; P = 0.013), a decrease in hemoglobin level of ≥20 and < 30 g/L (OR, 6.175; 95%CI, 1.033–10.919; P = 0.046) or ≥ 30 g/L (OR, 8.467; 95%CI, 1.248–17.426; P = 0.029), and postoperative albumin level ≥ 30 and < 35 g/L (OR, 2.552; 95%CI, 1.112–5.857; P = 0.027) or < 30 g/L (OR, 5.517; 95%CI, 2.047–18.148; P = 0.012) were associated with PLL. Conclusion Neoadjuvant chemotherapy, postoperative anemia and postoperative hypoproteinemia are risk factors for PLL.

Laparoscopic or Minimally Invasive Surgery in the Treatment of Cervical Cancer

Cervical cancer is the most common cause of death in female patients over 45 years of age. Surgical treatment (laparoscopic total hysterectomy and radical hysterectomy plus laparoscopic pelvic lymphadenectomy) is the most curative therapeutic resource in the initial stages (Ia1, Ia2 and Ib1). The treatment adopted in the development of this pathology is fundamental as the technique used to determine the prognosis of cervical cancer and obtain information on lymphatic involvement. Imaging techniques have advanced in recent years, but the only reliable way to detect lymph node involvement is the pathological study of the extracted pieces. The goal of laparoscopic staging is to assess bladder, bowel, and lymph node involvement and intra-abdominal disease. Laparoscopic pelvic and lumboaortic lymphadenectomy is effective in staging and treating gynecologic cancers. Laparoscopic lumboaortic lymphadenectomy has few complications, rescues an acceptable number of lymph nodes, and requires a shorter hospital stay. In addition, it identifies cervical cancers that require extended-field radiation therapy.
