Prospective assessment of urinary and bowel symptoms, and sexual function between laparoscopic assisted vaginal radical trachelectomy and radical hysterectomy.

OBJECTIVE: Radical trachelectomy is a valid alternative to radical hysterectomy in women with a desire to retain their fertility. Data regarding the oncological outcomes of radical trachelectomy are comparable with those of radical hysterectomy but information regarding urinary and sexual function is limited. The aim of this study was to prospectively evaluate and compare quality of life, urinary and bowel symptoms, and sexual dysfunction between patients who underwent laparoscopic assisted vaginal radical trachelectomy versus radical hysterectomy for early-stage cervical cancer. METHODS: Patients who underwent laparoscopic assisted vaginal radical trachelectomy or radical hysterectomy along with sentinel or systemic pelvic lymphadenectomy were included between May 2015 and January 2017. Patients were asked to complete a validated questionnaire (German pelvic symptom questionnaire) on bladder, bowel, prolapse, and sexual function, and total pelvic score, at least 48 hours before surgery and 6 months after surgery. RESULTS: A total of 51 patients were included. Of these, 26 patients (50.9%) underwent laparoscopic assisted vaginal radical trachelectomy and 25 (49.1%) underwent radical hysterectomy. No patient was converted to laparotomy. The majority of patients (76%) were diagnosed with International Federation of Gynecology and Obstetrics (FIGO 2018) stage 1B1 disease, with squamous cell carcinoma (54%) and grade II tumors (52%). Four patients (7.8 %) experienced perioperative complications (two grade II and two grade III complications according to the Clavien-Dindo classification). In the preoperative evaluation, the median scores for the four items of the questionnaire (bladder, bowel, prolapse, and sexual items) and total pelvic score were comparable between the two groups. The mean scores for radical hysterectomy and radical trachelectomy at the beginning of the study for bladder, bowel, prolapse, and sexual function were 0.93 versus 0.71, 0.71 versus 1.01, 0.12 versus 0.1, and 1.06 versus 1.0, respectively. On preoperative testing, the median scores for all four items of the questionnaire (pbladder=0.821, pbowel=0.126, pprolapse=0.449, psexual=0.965) and the total pelvic score (p=0.756) were comparable between the two groups. The radical hysterectomy group had worse total pelvic scores at the 6 month postoperative survey compared with baseline (p=0.03). There was no difference in bladder (p=0.07) or bowel symptoms (p=0.07) in the radical hysterectomy group comparing baseline with the 6 month assessment. Women undergoing radical hysterectomy experienced more urinary morbidity than women undergoing vaginal trachelectomy at 6 weeks (p=0.025). However, the mean bladder and pelvic scores in the 6 month control were comparable between patients who had and those who had not experienced urinary morbidity (pbladder=0.127, ptotal pelvic score=0.480). CONCLUSION: Patients undergoing laparoscopic assisted vaginal radical trachelectomy had similar pelvic scores in both the preoperative and postoperative periods. However, patients undergoing radical hysterectomy showed worse total pelvic scores on the postoperative assessment compared with the baseline evaluation. Urinary dysfunction in the early postoperative phase was more common in the radical hysterectomy group than in trachelectomy group.

Oncologic Safety of Laparoscopy in the Surgical Treatment of Type II Endometrial Cancer.

BACKGROUND: Laparoscopy is considered the method of choice in the operative treatment of type I endometrial carcinoma (EC). However, there is a paucity of data regarding the safety of endoscopy for type II EC because these malignancies have several biological similarities with ovarian cancer. OBJECTIVES: This study aimed to evaluate the feasibility, operative outcomes, and oncologic safety of laparoscopic surgery in patients with type II EC. METHODS: A retrospective study with histologically confirmed serous or clear-cell EC without peritoneal carcinomatosis treated by laparoscopy (G1) or laparotomy (G2) was conducted. Procedures included hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and pelvic and para-aortic lymphadenectomy. RESULTS: From 2009 to 2015, 89 patients were included; 53 women underwent laparoscopy and 36 underwent laparotomy. No relevant epidemiological or oncologic difference between groups was observed. The mean number of removed pelvic nodes was 16 [±10] and 12 [±13] in group 1 (G1) and group 2 (G2), respectively (P = 0.127). The mean number of dissected para-aortic nodes was significantly greater in the laparoscopic group (11 [±9] vs 6 [±9], P = 0.006). Para-aortic metastasis was significantly more often observed in the endoscopy group (26% vs 13%, P = 0.04). Adjuvant therapies were given to 86% of the patients in the study and 75% in the control group (P = 0.157). No excessive blood loss, casualty related to surgery, intraoperative complication, or conversion to laparotomy occurred in G1. Ten (18%) women from G1 and 36% (13/36) in G2 developed relevant postoperative complications (P = 0.03). The median duration of follow-up was 38 months for the laparoscopy and 47 months for the open surgery (P = 0.12). The 5-year overall and disease-free survival were similar, 86% versus 78% and 58% versus 51% for G1 and G2, respectively (P = 0.312). CONCLUSIONS: Laparoscopy is oncologically at least not inferior to laparotomy for the surgical treatment of type II EC. Endoscopic techniques are feasible, effective, result in significantly less morbidity, and improved quality staging. Although statistical significance was not reached, laparoscopy was associated with superior oncologic results.

Potential Surgical and Oncologic Consequences Related to Skin Tattoos in the Treatment of Cervical Cancer.

STUDY OBJECTIVE: Skin tattoos on the feet, legs, and lower abdominal wall are progressively gaining popularity. Consequently, the number of tattooed women with cervical cancer has significantly increased in the last decade. However, pigments of tattoo ink can be transported to regional lymph nodes and potentially clog lymphatic pathways that might also be used by sentinel labeling substances. Therefore, here we report whether the presence of tattoo ink affected pelvic lymph nodes in women with early cervical cancer and discuss its potential oncologic and surgical consequences. DESIGN: Prospective observational study. SETTING: University Hospital in Hamburg, Germany (Canadian Task Force classification II2). PATIENTS: Women affected by cervical cancer. INTERVENTIONS: Between January 2014 and May 2016, 267 laparoscopic oncologic operations, including at least a pelvic sentinel or complete lymphadenectomy, were performed in the Department of Advanced Surgical and Oncologic Gynecology, Asklepios Hospital, Hamburg, Germany. Among these, 191 patients were affected by cervical cancer. MEASUREMENTS AND MAIN RESULTS: Data of patients in whom dyed lymph nodes without the use of patent blue as a sentinel marker or different from blue-colored pelvic lymph nodes in the case of sentinel procedure were identified and prospectively collected. RESULTS: In 9 patients, skin tattoos localized in the lower extremities caused discoloration of at least 1 pelvic lymph node. This effect was observed in 40% of women (9/23) with tattoos in this area of the body. Mean patient age was 34 years (range, 27-56). All women had cutaneous tattoos on their feet or legs, and in 1 woman an additional tattoo situated on the inferior abdominal wall was observed. The stage of cervical cancer was FIGO IB1 in all cases. One woman was at the 16th week of gestation at the time of cancer diagnosis. On average, 26 pelvic lymph nodes (range, 11-51) were harvested from both pelvic basin sides. None of the removed lymph nodes was tumor involved. Three patients (33%) developed postoperatively infected lymphoceles on the side of the tattooed lymph nodes, and 1 woman had multiple episodes of fever without a clear origin. CONCLUSION: In women affected by cervical cancer with skin tattoos located in the lower limbs, the pelvic lymph nodes can be partially or totally occupied by the ink. This must be taken into consideration, especially for women scheduled exclusively for sentinel node biopsy. Infectious complications related to nodal dissection, in particular infected lymphoceles, may be more frequent in this population.

Molecular Diagnosis for Nodal Metastasis in Endoscopically Managed Cervical Cancer: The Accuracy of the APTIMA Test to Detect High-risk Human Papillomavirus Messenger RNA in Sentinel Lymph Nodes.

STUDY OBJECTIVE: To evaluate the feasibility and accuracy of a commercially available test to detect E6/E7 mRNA of 14 subtypes of high-risk HPVs (APTIMA; Hologic, Bedford, MA) in the sentinel lymph nodes of CC patients laparoscopically operated. DESIGN: Prospective pilot study. SETTING: The study was conducted in the Department of Advanced Operative and Oncologic Gynecology, Asklepios Hospital, Hamburg, Germany. PATIENTS: 54 women with HPV-positive CC submitted to laparoscopic sentinel node biopsy alone or sentinel node biopsy followed by systematic pelvic and/or para-aortic endoscopic lymphadenectomy. INTERVENTIONS: All removed sentinel lymph nodes (SLNs) underwent sample collection by cytobrush for the APTIMA assay before frozen section. MEASUREMENTS: Results obtained with the HPV mRNA test were compared with the definitive histopathological analysis of the SLNs and additional lymph nodes removed. RESULTS: A total of 125 SLNs (119 pelvic and 6 paraaortic) were excised with a mean number of 2.3 SLNs per patient. Final histopathologic analysis confirmed nodal metastases in 10 SLNs from 10 different patients (18%). All the histologically confirmed metastatic lymph nodes were also HPV E6/E7 mRNA positive, resulting in a sensitivity of 100%. Four histologically free sentinel nodes were positive for HPV E6/E7 mRNA, resulting in a specificity of 96.4%. CONCLUSION: The HPV E6/E7 mRNA assay in the SLNs of patients with CC is feasible and highly accurate. The detection of HPV mRNA in 4 women with negative SLNs might denote a shift from microscopic identification of metastasis to the molecular level. The prognostic value of this findings awaits further verification.

Symptomatic Lymphocele Formation After Sentinel Lymph Node Biopsy for Early Stage Cervical Cancer.

In early stage cervical cancer, nodal status is the most important prognostic factor, and execution of retroperitoneal lymphadenectomy is currently an integral part of surgical therapy. Sentinel lymph node biopsy has been progressively incorporated with surgical therapy and could reduce morbidity. However, the current incidence of complications exclusively related to the procedure is unknown. We report on a 29-year-old woman affected by cervical cancer (Fédération Internationale de Gynécologie et d'Obstétrique Stage 1b1), who underwent sentinel lymph node biopsy in combination with radical vaginal trachelectomy, and who later developed a symptomatic pelvic lymphocele that required surgical therapy. Conservative procedures in the pelvic lymph nodes are not free of complications, especially with regard to the formation of symptomatic lymphoceles. This report brings to light an important discussion about the exact magnitude of the complications associated with the procedure.

Oncologic Concerns regarding Laparoscopic Cytoreductive Surgery in Patients with Advanced Ovarian Cancer Submitted to Neoadjuvant Chemotherapy.

BACKGROUND: Presently, the use of laparoscopy in advanced ovarian cancer (AOC) is extremely controversial. In the era of neoadjuvant chemotherapy (NACT), endoscopic debulking surgery could be a reasonable alternative for selected patients with primarily unresectable disease. OBJECTIVES: To evaluate the feasibility as well as the operative and oncologic safety of laparoscopic debulking surgery in patients with AOC submitted to NACT. METHODS: This is a pilot observational study on initially unresectable, high-grade serous ovarian cancer treated with a sequence of 6 cycles of carboplatin and paclitaxel followed by debulking surgery performed by laparoscopy (group 1) or laparotomy (group 2). The inclusion criteria were clinical complete response, CA-125 normalization, imaging without disease in critical areas, and optimal cytoreduction. RESULTS: From January 2011 to March 2014, 21 patients were included. Ten women underwent laparoscopy and 11 laparotomy. No epidemiological or oncologic differences were observed between the groups. No surgery-related casualties, intraoperative complications, conversion to laparotomy, or excessive blood loss or transfusion was detected in the laparoscopic procedures. The mean time of operation was 292 min. The length of hospital stay averaged 3.6 days. Two women in group 1 developed relevant complications. After a mean follow-up of 20 months, the recurrence rates were similar, i.e. 80% in group 1 versus 88% in group 2. Although statistical significance was not reached, the mortality related to cancer was considerably higher (20 vs. 0%; p = 0.086) and the mean chemotherapy-free interval was markedly shorter in group 1 (13.3 vs. 20.5 months; p = 0.288). CONCLUSION: Laparoscopic optimal debulking surgery after NACT is feasible and effective in selected patients. Nevertheless, laparoscopy was substantially associated with inferior oncologic results. Endoscopic cytoreduction in AOC should be cautiously suggested until larger prospective trials confirm the observed results.

Laparoscopic Fertility-preserving Treatment of a Pure Nongestational Choriocarcinoma of the Ovary: Case Report and Review of Current Literature.

This case report demonstrates the feasibility of laparoscopic and fertility-preserving approach in nongestational choriocarcinoma of the ovary (NGCO). Pure NGCO is a rare malignant condition. In the last decade, only 14 cases have been reported in the literature. The use of laparoscopy and fertility-preserving procedures in nonepithelial ovarian malignancies is extremely controversial. A 23-year-old woman underwent emergency laparoscopy due to acute abdominal pain associated with an 8-cm large adnexal mass. The initial procedure consisted only of a left oophoroplasty, and histology revealed a tumor of high malignant potential compatible with a primary NGCO. Approximately 3 weeks after initial surgery, she was submitted to a laparoscopic staging surgery, including left adnexectomy, omentectomy, peritoneal biopsies, and retroperitoneal lymphadenectomy. Final pathology confirmed an International Federation of Gynecology and Obstetrics stage IIB NGCO. Before initiation of adjuvant chemotherapy based on 3 courses of bleomycin, etoposide, and cisplatin, the patient received goserelin for ovarian suppression. Nine months after therapy, the patient presented no signs of recurrence and reassumed normal menstruation cycles with normal levels of gonadotropins and tumor markers. The current report brings new insights into the possibility of using use minimally invasive surgery and a combination of fertility-preserving methods for the treatment of NGCO.

Vaginal Morcellation Inside Protective Pouch: A Safe Strategy for Uterine Extration in Cases of Bulky Endometrial Cancers: Operative and Oncological Safety of the Method.

OBJECTIVE: To evaluate the operative and oncologic outcomes of an innovative technique for organ morcellation in patients scheduled for laparoscopic treatment of uterine malignancies. BACKGROUND: Endoscopy is currently considered the standard of care for the operative treatment of endometrial cancer; however, the use of minimal invasive surgery (MIS) is restricted in patients with a bulky uterus or narrow vagina. Conventional unprotected intraperitoneal uterine fragmentation is indeed contraindicated in these cases. Consequently, oncologically safe methods to render these patients eligible for MIS are urgently needed. INTERVENTION: Prospective study of women with histologically proven endometrial cancer in which uterus removal was a realistic concern owing to both organ size and proportionality. The patients underwent laparoscopic staging, including retroperitoneal lymphadenectomy, total hysterectomy, and bilateral salpingo-oophorectomy, followed by vaginal morcellation of the uterus inside a protective pouch (LapSac). RESULTS: In our series of 30 cases, we achieved successful completion in all patients, without conversion to laparotomy. No surgery-related casualty or intraoperative morbidity was observed. The mean organ size was 246 g (range, 148-420 g), and the average additional operative time related to vaginal morcellation was 16 minutes (range, 9-28 minutes). Proper histopathological staging according to 2009 FIGO staging guidelines could be performed in all specimens. Two patients (6%) presented with significant postoperative complications, 1 each with vesicovaginal fistula and vaginal vault dehiscence. Fourteen patients (46%) needed adjuvant therapy. After a median follow-up of 20 months (range, 6-38 months), the 12-month and 24-month overall survival was 100% and 73.4% (95% confidence interval, 51%-96%), respectively. Four patients with positive lymph nodes died of distant metastasis. No case of pelvic or local relapse was observed. CONCLUSION: Vaginal morcellation following oncologic principles is a feasible method that permits rapid uterine extraction and potentially avoids unnecessary laparotomies. This series suggests that the technique may be oncologically safe and also can be used in cases of uterine pathology of uncertain malignancy.

Laparoscopic sentinel lymph node detection after hysteroscopic injection of technetium-99 in patients with endometrial cancer.

BACKGROUND AND OBJECTIVES: Endometrial cancer (EC) has an increasing incidence worldwide. Despite the unequivocal prognostic importance of nodal status, systematic lymphadenectomy is associated to elevated morbidity. Sentinel lymph node (SLN) biopsy is designed to avoid extensive nodal dissection and provide crucial oncologic information. The goal of this prospective study was to determine the feasibility, safety, and accuracy of laparoscopic SLN biopsy in EC obtained through hysteroscopic injection of technetium-99 (Tc-99). METHODS: From January 2008 to December 2012, a total of 42 women with EC were included in the study. We injected 20 mBq of Tc-99 hysteroscopically underneath the tumor minutes before definitive surgery. Thereafter, laparoscopic SLN identification /biopsy followed by pelvic and para-aortic lymphadenectomy, hysterectomy, and bilateral salpingo-oophorectomy were executed. RESULTS: The total number of removed nodes was 970. The detection rate of the method was 73% (31/42). Among the 70 isolated SLNs, 35% (24) were exclusively identified in the para-aortic area. Fourteen patients (45%) had SLN only in the pelvic region, whereas 11 (35%) had SLN in both pelvic and para-aortic areas and 6 women (20%) had isolated para-aortic SNL. Nodal metastases were histologically confirmed in 9 patients (22%), and SLN was identified in 7 of 9 patients (78%). Although the obtained specificity was 100% and the negative predictive value was 89%, the sensitivity was only 58% (false-negative rate of 42%). CONCLUSIONS: We could demonstrate that endoscopic SLN biopsy obtained through hysteroscopic injection of Tc-99 is a feasible and safe method. Despite the restricted number of included patients in this series, the obtained sensitivity and false-negative rates raise some questions about the real accuracy of the procedure in EC. Larger validation trials requiring quality pelvic and para-aortic lymphadenectomy are essential to correctly evaluate the method.

Uncommon synchronous association between ovarian carcinoma and gastrointestinal stromal tumor: a case study and literature review.

BACKGROUND: The association of gastrointestinal stromal tumors (GIST) and other cancers is well known, but its synchronous occurrence with gynecological malignancies is very uncommon. Usually, the diagnosis is accidentally established. We describe a patient with GIST and concurrent ovarian cancer and discuss the clinical implications of this finding. CASE REPORT: A 64-year-old woman with a prior diagnosis of ovarian cancer developed a second recurrence after having undergone two operations and adjuvant chemotherapy. While tumor debulking was performed, a small, nonsuspicious lesion was removed from the greater curvature of the stomach. Histology revealed a GIST. CONCLUSION: The association of GIST and ovarian cancer is a rarity and its synchronicity may alter the oncological prognosis and therapy of the patient.
