A fertility-preserving option in early cervical carcinoma: laparoscopy-assisted vaginal radical trachelectomy and pelvic lymphadenectomy

OBJECTIVE: Laparoscopic vaginal radical trachelectomy is a fertility-preserving alternative to radical hysterectomy or chemoradiation in young women with stage IA2 to IB cervical cancers. The aim of this study is to describe the feasibility and outcome of laparoscopic radical vaginal trachelectomy and pelvic lymphadenectomy in women treated with early cervical cancers who wish to maintain fertility. STUDY DESIGN: From August 2000 through December 2004, 16 patients were offered this procedure. Patients were selected for this treatment on the basis of favorable cervical tumors and a desire to maintain fertility. Laparoscopic pelvic lymphadenectomies were performed in all patients. Vaginal radical trachelectomy was performed immediately if removed lymph nodes were negative. Obstetrical and oncological outcomes were evaluated. RESULTS: Sixteen women underwent this procedure. The mean operative time was 142 min (115-178 min), with a mean blood loss of 180 ml (120-230 ml), and the average hospital stay was 6.7 days. No intraoperative or postoperative complications occurred. With an average follow-up of 28.2 months, there have been no recurrences. Five pregnancies have subsequently occurred, with two third-trimester deliveries, two miscarriages at 24 and 26 weeks' gestation, and one patient is currently 18 weeks' pregnant. CONCLUSIONS: Laparoscopy-assisted radical vaginal trachelectomy is an adequate treatment, with its minimally invasive procedure and shorter recovery time, for early-stage cervical cancer in women who wish to preserve fertility. However, fertility issues remain the largest unanswered problem with this technique.     

Isolated recurrence at the residual uterine cervix after abdominal radical trachelectomy for early cervical cancer

BACKGROUND: We report an isolated recurrence at the residual cervix shortly after abdominal radical trachelectomy for cervical cancer. CASE: A 34-year-old woman underwent radical abdominal trachelectomy and pelvic lymphadenectomy for FIGO stage IB1 squamous cell cervical cancer. The tumor measured 10 mm in maximum diameter with 4 mm of invasion. Histology showed lymph vascular space involvement with no infiltration of adjacent structures and no pelvic lymph node metastases. Tumor-free resection margins exceeded 15 mm. At the 6-month follow-up examination, cervical cytology showed cells suspicious for recurrent cervical cancer. Abdominal hysterectomy was performed and histology showed an isolated 3-mm recurrence in the residual cervix. The patient is free of disease 8 months after hysterectomy. CONCLUSION: Recurrence at the residual cervix is a potential risk of abdominal trachelectomy for early cervical cancer. Patients should be counseled accordingly and followed closely.     

Radical vaginal trachelectomy after supracervical hysterectomy

BACKGROUND: Radical vaginal trachelectomy (RVT) is an acceptable approach when applied toward a select group of patients with early stage cervical carcinoma. It is less invasive, can maintain fertility, and can be ideal in patients with significant comorbid factors compared to abdominal approaches. A small subset of patients with a previous supracervical hysterectomy can pose a surgical dilemma. CASE: An 81-year-old woman with a history of severe cardiac disease on routine gynecological examination was found to have adenocarcinoma in situ with a focus suspicious for invasion of the cervical stump diagnosed by cone biopsy. She previously had a supracervical hysterectomy for benign disease of the uterus. A RVT was performed as definitive treatment and the patient recovered without complications. CONCLUSION: In the rare case that presents with a history of supracervical hysterectomy, RVT with some technical modifications can still be considered as a therapeutic option for early stage cervical carcinoma.     

Systematic comparison of radical vaginal trachelectomy and radical hysterectomy in the treatment of early-stage cervical cancer

Objective

To review the effects of radical vaginal trachelectomy (RVT) and radical hysterectomy (RH) on overall progression-free survival rate, and intraoperative and postoperative complications in patients with cervical cancer (FIGO stage IA-IB1).

Methods

Electronic searches for studies of RVT and RH in the treatment of cervical cancer between 1994 and January 2010 were made on MEDLINE, the Cochrane Library, the China National Knowledge Infrastructure, and the Wan Fang dissertation database.

Results

No significant differences were found between RVT and RH in 5-year overall survival rate (relative risk [RR] 0.97; 95% confidence interval [CI], 0.93-1.02); 5-year progression-free survival rate (RR 0.99; 95% CI, 0.95-1.02); intraoperative complications (RR 1.99; 95% CI, 0.61-6.52)]; and postoperative complications (RR 0.36; 95% CI, 0.10-1.27). There were fewer blood transfusions (RR 0.33; 95% CI, 0.12-0.90), less blood loss, and shorter hospital stays in patients undergoing RVT.

Conclusion

Radical vaginal trachelectomy should be considered as a viable treatment option for young patients with early cervical cancer (FIGO stage IA-IB1) who wish to preserve their fertility.     

First case of a centropelvic recurrence after radical trachelectomy: literature review and implications for the preoperative selection of patients

BACKGROUND: To report the first case of a centropelvic recurrence in a patient who underwent a radical trachelectomy (RT) for a stage IB1 cervical carcinoma. CASE: A 32-year-old woman presented with a stage IB1 adenocarcinoma that was treated by radical trachelectomy. The tumor measured 21 x 20 mm. Minimal lymphatic space involvement was observed close to the tumor associated with 30 negative nodes and free margins. The upper free margin measured only 5 mm. Twenty-six months after the surgical procedure, the patient became pregnant. Clinical examination and pap smears were normal 2 months prior. During the first trimester, ultrasonography depicted a suspicious lesion in the bladder. Abdomino-pelvic magnetic resonance imaging (MRI) demonstrated a suspicious 20-mm tumor in the bladder associated with suspicious common iliac nodes. Cystoscopy and biopsies were carried out which confirmed recurrent disease. The patient received external radiation therapy combined with concomitant chemotherapy. CONCLUSIONS: More data are required to establish what is the safety distance between the tumor and the uterine transection. A distance of 5 mm or less is likely to be too limited for radical trachelectomy to be accepted as treatment for cervical cancer.

Prevalence of lymph nodes in the parametrium of radical vaginal trachelectomy (RVT) specimen

Objective

In order to evaluate radicality in fertility preserving surgery in women with early invasive cervical cancer we analyzed the parametrium of specimens of patients treated by radical vaginal trachelectomy for the presence of lymph nodes. We tried to identify morphologic factors associated with the presence of parametrial lymph nodes.

Methods

We analyzed surgical specimens of 112 patients who underwent radical trachelectomy between June 2004 and April 2009 at the Department of Gynecologic Oncology at Charité Campus Benjamin Franklin and Campus Mitte. All parametrial tissue was step sectioned and a total of 1878H&;E stained histological sections were analyzed.

Results

In 8 patients (7.1%) a total of 13 lymph nodes were detected. Five lymph nodes in four patients had been primarily detected by routine histological examination. In one of these patients (0.9%) a 2 mm lymph node metastasis was found. Serial sectioning revealed additional seven lymph nodes in four patients. The thickness of parametrium correlated significantly with the presence of lymph nodes in the parametrium.

Conclusion

The presence of small lymph nodes in the parametrium of specimens of radical trachelectomy is low. In patients with early-stage cervical cancer, the incidence of metastasis is less than 1%. Preoperative assessment of the volume of the parametrium may indicate which patients need parametrial resection.     

Ovarian recurrence after radical trachelectomy for adenocarcinoma of the cervix

Radical trachelectomy is an effective fertility-sparing treatment for women with early-stage cervical cancer. We describe the first reported ovarian recurrence after radical trachelectomy for stage IB1 adenocarcinoma cervical cancer.     

Pregnancies after radical vaginal trachelectomy for early-stage cervical cancer

Objective: The purpose of this study was to evaluate the role of fertility-preserving surgery in the treatment of early-stage cervical cancer. Study Design: We retrospectively reviewed our first 30 patients treated by laparoscopic pelvic lymphadenectomy, followed by radical vaginal trachelectomy, from October 1991 to April 1998. Results: The median age of the patients was 32 years (range 22-42 years); 15 were nulligravid and 19 nulliparous. Twenty cancers were at stage IB, 1 was at stage IA₁ , 7 were at stage IA₂ , and 2 were at stage IIA. The majority (18/30) were squamous. Two lesions were >2 cm in size, and only 4 had vascular space invasion. The median operative time was 285 minutes (range 155-455 minutes), median blood loss 200 mL (range 50-1200 mL), and median hospital stay 4 days (range 2-9 days). There were 4 intraoperative complications—2 attributed to the trachelectomy and 2 resulting from the lymphadenectomy. The current median follow-up time is 25 months (range 1-79 months). One patient had a recurrence in the left parametrium 18 months after vaginal radical trachelectomy and died of metastatic disease. The only 6 patients attempting pregnancy so far have succeeded: 4 have had healthy babies delivered by cesarean section at 39, 38, 34, and 25 weeks of gestation. Two are currently 33 and 8 weeks pregnant. Conclusion: Radical vaginal trachelectomy appears to be a valuable procedure in well-selected patients with early-stage cervical cancer. Successful pregnancies are definitely possible after this procedure. This new surgical technique warrants further careful evaluation to determine precise indications.

Successful twin pregnancy after vaginal radical trachelectomy using transabdominal cervicoisthmic cerclage

The outcome of vaginal radical trachelectomy (VRT) for the management of early cervical cancer is comparable to that achieved with radical hysterectomy. Although VRT preserves the potential for pregnancy, the outcome of twin pregnancies following VRT is poor. We report a successful twin pregnancy after VRT using transabdominal cervicoisthmic cerclage.     

Surgical morbidity associated with radical trachelectomy and radical hysterectomy

OBJECTIVES: To examine intra-operative, short and longer term morbidity associated with Radical Trachelectomy (RT) within our cohort of patients, compared with conventional Radical Hysterectomy (RH). METHODS: A retrospective case note review comprising 29 RT and 50 RH patients. Patients who required adjuvant treatment were excluded. Operative data, short-term and long-term complications were recorded. Long-term problems were included only if they had been of persistent nature. RESULTS: The median age and follow up period for the RH group were 40 years and 60 months and for RT group 30.5 years and 25 months. There were significant differences between RH and RT groups in median operative time (260 versus 187 min), blood loss (1000 versus 400 ml), transfusion requirement (75% versus 12%), analgesic requirement (8 versus 3.5 days) and hospital stay (11 versus 6 days). Bladder hypotonia requiring prolonged catheterisation was more frequent in RH group (P = 0.004). There was no apparent difference in psychosexual problems between the two groups (17 versus 16%). Complications of deep dyspareunia (P = 0.009), excessive vaginal discharge (P = 0.01), and upper thigh parasthesia (P = 0.05) were noted to be significantly higher in the RT group. Specific problems encountered in the RT group included; dysmenorrhea (24%), irregular menstruation (17%), recurrent candidiasis (14%), cervical suture problems (14%), isthmic stenosis (10%) and prolonged amenorrhea (7%). CONCLUSION: RT is associated with less operative and short-term morbidity compared with conventional RH. In addition to specific complications associated with RT, in our experience, there are long-term morbidities that are not as commonly observed in RH.     

The vaginal radical trachelectomy: an update of a series of 125 cases and 106 pregnancies

Objective

To review our first consecutive 125 vaginal radical trachelectomies (VRT) to assess the oncologic, fertility and obstetrical outcomes.

Methods

Data from our prospective database was used to identify all VRT planned between October 1991 to March 2010 in patients with early-stage cervical cancer (stages IA, IB and IIA). Chi-square test, Fisher's exact test and Student t-test were used to compare baseline characteristics and Kaplan-Meier survival curves were constructed and compared with the use of the log-rank test.

Results

During the study period, 140 VRT were planned and 125 were performed. The median age of the patients was 31 and 75% were nulliparous. The majority of the lesions were stage IA2 (21%) or IB1 (69%) and 41% were grade 1. In terms of histology, 56% were squamous and 37% were adenocarcinomas. Vascular space invasion was present in 29% of cases, and 88.5% of the lesions measured ≤ 2 cm. The mean follow-up was 93 months (range: 4-225 months). There were 6 recurrences (4.8%) and 2 deaths (1.6%) following VRT. The actuarial 5-year recurrence-free survival was 95.8% [95% CI: 0.90-0.98], whereas it was 79% [95% CI: 0.49-0.93] in the group where the VRT was abandoned (p = 0.001). Higher tumor grade, LVSI and size > 2 cm appeared to be predictive of the risk of abandoning VRT (p = 0.001, p = 0.025 and p = 0.03 respectively). Tumor size > 2 cm was statistically significantly associated with a higher risk of recurrence (p = 0.001). In terms of obstetrical outcome, 58 women conceived a total of 106 pregnancies. The first and second trimester miscarriage rates were 20% and 3% respectively, and 77 (73%) of the pregnancies reached the third trimester, of which 58 (75%) delivered at term. Overall, 15 (13.5%) patients experienced fertility problems, 40% of which were due to cervical factor. Twelve (80%) were able to conceive, the majority with assisted reproductive technologies.

Conclusion

VRT is an oncologically safe procedure in well-selected patients with early-stage disease. Lesion size > 2 cm appears to be associated with a higher risk of recurrence and a higher risk of abandoning the planned VRT. Fertility and obstetrical outcomes post VRT are excellent.     

Reproductive outcomes of patients undergoing radical trachelectomy for early-stage cervical cancer

Objective

To report the reproductive outcomes of patients undergoing fertility-preserving radical trachelectomy (RT) for the treatment of early-stage cervical cancer.

Methods

We analyzed data from our institution's first 105 patients who underwent attempted fertility-sparing surgery with radical trachelectomy, pelvic lymphadenectomy, and cerclage from November 2001 to October 2010.

Results

Of the 105 patients who underwent attempted RT, 77 (73%) did not require a conversion to radical hysterectomy or postoperative treatment. The median age was 32 (range, 25-38 years). Most patients (75%) had stage IB1 disease. Sixty-six patients (63%) were nulliparous. Thirty-five women were actively attempting conception 6 months after surgery, and 23 (66%) women were successful in conceiving: there were 20 live births, 3 elective terminations, and 4 spontaneous miscarriages. Four patients had 2 pregnancies each; all delivered their second pregnancy between 32 and 36 weeks. Cerclage erosion through the vaginal wall occurred in 6 cases and was treated by transvaginal removal of protruding suture material. One of these patients experienced a second trimester miscarriage.

Conclusions

The majority of women who attempted to conceive after radical trachelectomy were successful, and most of their pregnancies resulted in full-term births. Assisted reproduction played an important role in select women. Cerclage likely contributed to a post-trachelectomy uterine ability to carry a pregnancy to the third trimester. The second post-trachelectomy pregnancy appears to be at higher risk for preterm delivery than the first pregnancy.     

Pregnancy outcomes in patients after radical trachelectomy

OBJECTIVES: This study was undertaken to review and analyze the fertility and pregnancy outcomes in patients who have undergone radical trachelectomy as the method of management of invasive carcinoma of the cervix. STUDY DESIGN: All preoperative, operative, and follow-up data were collected prospectively. Perinatal information was completed by chart reviews and patient questionnaires. RESULTS: Of 80 patients having undergone the above procedure, 39 have attempted to conceive for a median of 11 months (range 1-85). There have been a total of 22 pregnancies in 18 patients (4 patients pregnant twice). Of the 22 pregnancies, 18 were viable, with 12 progressing to term and delivering by caesarean section. Preterm premature rupture of membranes was the primary cause of preterm delivery. CONCLUSION: This series confirms that pregnancy is a safe and realistic outcome for women undergoing radical trachelectomy for invasive carcinoma of the cervix. Given the apparently high incidence of preterm premature rupture of membranes, these pregnancies should be managed as high risk.
