RESUMO

BACKGROUND: In cervical cancer, presence of lymph-node macrometastases (MAC) is a major prognostic factor and an indication for adjuvant treatment. However, since clinical impact of micrometastases (MIC) and isolated tumor-cells (ITC) remains controversial, we sought to identify a cut-off value for the metastasis size not associated with negative prognosis. METHODS: We analyzed data from 967 cervical cancer patients (T1a1L1-T2b) registered in the SCCAN (Surveillance in Cervical CANcer) database, who underwent primary surgical treatment, including sentinel lymph-node (SLN) biopsy with pathological ultrastaging. The size of SLN metastasis was considered a continuous variable and multiple testing was performed for cut-off values of 0.01-1.0 mm. Disease-free survival (DFS) was compared between N0 and subgroups of N1 patients defined by cut-off ranges. RESULTS: LN metastases were found in 172 (18%) patients, classified as MAC, MIC, and ITC in 79, 54, and 39 patients, respectively. DFS was shorter in patients with MAC (HR 2.20, P = 0.003) and MIC (HR 2.87, P < 0.001), while not differing between MAC/MIC (P = 0.484). DFS in the ITC subgroup was neither different from N0 (P = 0.127) nor from MIC/MAC subgroups (P = 0.449). Cut-off analysis revealed significantly shorter DFS compared to N0 in all subgroups with metastases ≥0.4 mm (HR 2.311, P = 0.04). The significance of metastases <0.4 mm could not be assessed due to limited statistical power (<80%). We did not identify any cut-off for the size of metastasis with significantly better prognosis than the rest of N1 group. CONCLUSIONS: In cervical cancer patients, the presence of LN metastases ≥0.4 mm was associated with a significant negative impact on DFS and no cut-off value for the size of metastasis with better prognosis than N1 was found. Traditional metastasis stratification based on size has no clinical implication.

RESUMO

OBJECTIVE: The "intermediate-risk" (IR) group of early-stage cervical cancer patients is characterized by negative pelvic lymph nodes and a combination of tumor-related prognostic risk factors such as tumor size ≥2 cm, lymphovascular space invasion (LVSI), and deep stromal invasion. However, the role of adjuvant treatment in these patients remains controversial. We investigated whether adjuvant (chemo)radiation is associated with a survival benefit after radical surgery in patients with IR cervical cancer. METHODS: We analyzed data from patients with IR cervical cancer (tumor size 2-4 cm plus LVSI OR tumor size >4 cm; N0; no parametrial invasion; clear surgical margins) who underwent primary curative-intent surgery between 2007 and 2016 and were retrospectively registered in the international multicenter Surveillance in Cervical CANcer (SCCAN) study. RESULTS: Of 692 analyzed patients, 274 (39.6%) received no adjuvant treatment (AT-) and 418 (60.4%) received radiotherapy or chemoradiotherapy (AT+). The 5-year disease-free survival (83.2% and 80.3%; PDFS = 0.365) and overall survival (88.7% and 89.0%; POS = 0.281) were not significantly different between the AT- and AT+ groups, respectively. Adjuvant (chemo)radiotherapy was not associated with a survival benefit after adjusting for confounding factors by case-control propensity score matching or in subgroup analyses of patients with tumor size ≥4 cm and <4 cm. In univariable analysis, adjuvant (chemo)radiotherapy was not identified as a prognostic factor in any of the subgroups (full cohort: PDFS = 0.365; POS = 0.282). CONCLUSION: Among patients with IR early-stage cervical cancer, radical surgery alone achieved equal disease-free and overall survival rates to those achieved by combining radical surgery with adjuvant (chemo)radiotherapy.

RESUMO

BACKGROUND: International guidelines recommend tailoring the radicality of hysterectomy according to the known preoperative tumor characteristics in patients with early-stage cervical cancer. OBJECTIVE: This study aimed to assess whether increased radicality had an effect on 5-year disease-free survival in patients with early-stage cervical cancer undergoing radical hysterectomy. The secondary aims were 5-year overall survival and pattern of recurrence. STUDY DESIGN: This was an international, multicenter, retrospective study from the Surveillance in Cervical CANcer (SCCAN) collaborative cohort. Patients with the International Federation of Gynecology and Obstetrics 2009 stage IB1 and IIA1 who underwent open type B/C1/C2 radical hysterectomy according to Querleu-Morrow classification between January 2007 and December 2016, who did not undergo neoadjuvant chemotherapy and who had negative lymph nodes and free surgical margins at final histology, were included. Descriptive statistics and survival analyses were performed. Patients were stratified according to pathologic tumor diameter. Propensity score match analysis was performed to balance baseline characteristics in patients undergoing nerve-sparing and non-nerve-sparing radical hysterectomy. RESULTS: A total of 1257 patients were included. Of note, 883 patients (70.2%) underwent nerve-sparing radical hysterectomy, and 374 patients (29.8%) underwent non-nerve-sparing radical hysterectomy. Baseline differences between the study groups were found for tumor stage and diameter (higher use of non-nerve-sparing radical hysterectomy for tumors >2 cm or with vaginal involvement; P<.0001). The use of adjuvant therapy in patients undergoing nerve-sparing and non-nerve-sparing radical hysterectomy was 27.3% vs 28.6%, respectively (P=.63). Five-year disease-free survival in patients undergoing nerve-sparing vs non-nerve-sparing radical hysterectomy was 90.1% (95% confidence interval, 87.9-92.2) vs 93.8% (95% confidence interval, 91.1-96.5), respectively (P=.047). Non-nerve-sparing radical hysterectomy was independently associated with better disease-free survival at multivariable analysis performed on the entire cohort (hazard ratio, 0.50; 95% confidence interval, 0.31-0.81; P=.004). Furthermore, 5-year overall survival in patients undergoing nerve-sparing vs non-nerve-sparing radical hysterectomy was 95.7% (95% confidence interval, 94.1-97.2) vs non-nerve-sparing 96.5% (95% confidence interval, 94.3-98.7), respectively (P=.78). In patients with a tumor diameter ≤20 mm, 5-year disease-free survival was 94.7% in nerve-sparing radical hysterectomy vs 96.2% in non-nerve-sparing radical hysterectomy (P=.22). In patients with tumors between 21 and 40 mm, 5-year disease-free survival was 90.3% in non-nerve-sparing radical hysterectomy vs 83.1% in nerve-sparing radical hysterectomy (P=.016) (no significant difference in the rate of adjuvant treatment in this subgroup, P=.47). This was confirmed after propensity match score analysis (balancing the 2 study groups). The pattern of recurrence in the propensity-matched population did not demonstrate any difference (P=.70). CONCLUSION: For tumors ≤20 mm, no survival difference was found with more radical hysterectomy. For tumors between 21 and 40 mm, a more radical hysterectomy was associated with improved 5-year disease-free survival. No difference in the pattern of recurrence according to the extent of radicality was observed. Non-nerve-sparing radical hysterectomy was associated with better 5-year disease-free survival than nerve-sparing radical hysterectomy after propensity score match analysis.

RESUMO

BACKGROUND: Up to 26% of patients with early-stage cervical cancer experience relapse after primary surgery. However, little is known about which factors influence prognosis following disease recurrence. Therefore, our aims were to determine post-recurrence disease-specific survival (PR-DSS) and to identify respective prognostic factors for PR-DSS. METHODS: Data from 528 patients with early-stage cervical cancer who relapsed after primary surgery performed between 2007 and 2016 were obtained from the SCANN study (Surveillance in Cervical CANcer). Factors related to the primary disease and recurrence were combined in a multivariable Cox proportional hazards model to predict PR-DSS. RESULTS: The 5-year PR-DSS was 39.1% (95% confidence interval [CI] 22.7%-44.5%), median disease-free interval between primary surgery and recurrence (DFI1) was 1.5 years, and median survival after recurrence was 2.5 years. Six significant variables were identified in the multivariable analysis and were used to construct the prognostic model. Two were related to primary treatment (largest tumour size and lymphovascular space invasion) and four to recurrence (DFI1, age at recurrence, presence of symptoms, and recurrence type). The C-statistic after 10-fold cross-validation of prognostic model reached 0.701 (95% CI 0.675-0.727). Three risk-groups with significantly differing prognoses were identified, with 5-year PR-DSS rates of 81.8%, 44.6%, and 12.7%. CONCLUSIONS: We developed the robust model of PR-DSS to stratify patients with relapsed cervical cancer according to risk profiles using six routinely recorded prognostic markers. The model can be utilised in clinical practice to aid decision-making on the strategy of recurrence management, and to better inform the patients.

RESUMO

INTRODUCTION: Recent evidence has shown adverse oncological outcomes when minimally invasive surgery is used in early-stage cervical cancer. The objective of this study was to compare disease-free survival in patients that had undergone radical hysterectomy and pelvic lymphadenectomy, either by laparoscopy or laparotomy. METHODS: We performed a multicenter, retrospective cohort study of patients with cervical cancer stage IA1 with lymph-vascular invasion, IA2, and IB1 (FIGO 2009 classification), between January 1, 2006 to December 31, 2017, at seven cancer centers from six countries. We included squamous, adenocarcinoma, and adenosquamous histologies. We used an inverse probability of treatment weighting based on propensity score to construct a weighted cohort of women, including predictor variables selected a priori with the possibility of confounding the relationship between the surgical approach and survival. We estimated the HR for all-cause mortality after radical hysterectomy with weighted Cox proportional hazard models. RESULTS: A total of 1379 patients were included in the final analysis, with 681 (49.4%) operated by laparoscopy and 698 (50.6%) by laparotomy. There were no differences regarding the surgical approach in the rates of positive vaginal margins, deep stromal invasion, and lymphovascular space invasion. Median follow-up was 52.1 months (range, 0.8-201.2) in the laparoscopic group and 52.6 months (range, 0.4-166.6) in the laparotomy group. Women who underwent laparoscopic radical hysterectomy had a lower rate of disease-free survival compared with the laparotomy group (4-year rate, 88.7% vs 93.0%; HR for recurrence or death from cervical cancer 1.64; 95% CI 1.09-2.46; P=0.02). In sensitivity analyzes, after adjustment for adjuvant treatment, radical hysterectomy by laparoscopy compared with laparotomy was associated with increased hazards of recurrence or death from cervical cancer (HR 1.7; 95% CI 1.13 to 2.57; P=0.01) and death for any cause (HR 2.14; 95% CI 1.05-4.37; P=0.03). CONCLUSION: In this retrospective multicenter study, laparoscopy was associated with worse disease-free survival, compared to laparotomy.

RESUMO

Recently the revised 2018 International Federation of Gynecology and Obstetrics (FIGO) staging system for cervical cancer was published. In this most recent classification, imaging modalities and pathologic information have been added as tools to determine the final stage of the disease. Although there are many merits to this new staging for cervical cancer, including more detailed categorization of early-stage disease as well as information on nodal distribution, the classification falls short in clarifying areas of controversy in the staging system. Many unanswered questions remain and, as such, a number of gaps lead to further debate in the interpretation of relevant clinical data. Factors such as measurement of tumor size, definition of parametrial involvement, ovarian metastases, lower uterine segment extension, lymph node metastasis, and imaging modalities are explored in this review. The goal is to focus on items that deserve further discussion and clarification in the most recent FIGO staging for cervical cancer.

RESUMO

A case study of a 38-year-old woman with a diagnosis of placental site trophoblastic tumor is presented. The patient had a 22-month history of amenorrhea since her last pregnancy, and a dilation and curettage procedure was performed after a 3.1×2.4×2.8 cm endometrial echogenic lesion was visualized on a pelvic ultrasound. When the diagnosis of placental site trophoblastic tumor was made by histopathologic and immunohistochemical analysis, complementary examinations including including pelvic magnetic resonance imaging (MRI) and a chest computed tomography (CT) were done. There was no evidence of disease outside the uterus, and a laparoscopic hysterectomy with bilateral salpingectomy was performed. After a surveillance period of 12 months, no disease recurrence was identified. Best imaging studies, treatment options, and proper surveillance for these type of tumors are discussed alongside the case study.

RESUMO

The major tenets in accurately assessing tumor size in patients with early stage cervical cancer currently include physical examination, imaging studies, and pathologic evaluation. It is estimated that when comparing clinical stage based on physical examination and final pathology, the concordance diminishes as stage increases: 85.4%, 77.4%, 35.3%, and 20.5% for stage IB1, IB2, IIA, and IIB, respectively. Vaginal involvement and larger tumor diameter are considered the main causes of stage inaccuracy. When considering imaging studies, magnetic resonance imaging (MRI) provides the highest level of accuracy in the assessment of cervical tumor size. Its accuracy in determining tumor location within the cervix is approximately 91% and in predicting tumor size 93%. MRI imaging is also significantly more accurate in measuring tumor size, delineating cervical tumor boundaries, and local tumor extension when compared with computed tomography (CT) scan. When comparing with pelvic ultrasound, the accuracy of both imaging techniques (MRI and pelvic ultrasound) in the assessment of tumor size in small versus large tumors is comparable. Pertaining to pathology, the depth of invasion should be measured by convention from the nearest surface epithelium, which equates to tumor thickness. In the setting where tumor is found both in the conization and hysterectomy specimen, the horizontal extent should be measured by summing the maximum horizontal measurement in the different specimens and the depth of invasion measured as the maximum depth in either specimen. A new pattern-based classification for endocervical adenocarcinomas recommends the description of patterns of invasion for human papillomavirus (HPV)-related adenocarcinomas as this is associated with differing risks of lymph node involvement.

RESUMO

BACKGROUND: The Laparoscopic Approach to Cervical Cancer (LACC) trial demonstrated a higher rate of disease recurrence and worse disease-free survival in patients who underwent minimally invasive radical hysterectomy. OBJECTIVES: To evaluate surgical and oncological outcome of laparoscopic radical hysterectomy performed at Hospital Italiano in Buenos Aires, Argentina. METHODS: This retrospective study included all patients with cervical cancer, 2009 FIGO stage IA1, with lymphovascular invasion to IB1 (<4 cm) who underwent a laparoscopic radical hysterectomy between June 2010 and June 2015. Patients were eligible if they had squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma, and no lymph node involvement by imaging. Patients must have undergone a type C1 radical hysterectomy. Only patients who were treated by a laparoscopic approach were included. Patients were excluded if histopathology showed a component of neuroendocrine carcinoma before or after surgery; if they had synchronous primary tumors, history of abdominal or pelvic radiotherapy, or were operated on at an outside institution; and if they had only surgery and no follow-up in our institution. Relapse rate and disease-free survival were evaluated using the Kaplan-Meier method. RESULTS: A total of 108 patients were evaluated. The median age was 41 years (range 27-70). Distribution of histologic sub-types was squamous carcinoma in 77 patients (71%), adenocarcinoma in 27 patients (25%), and adenosquamous carcinoma in four patients (4%). Ninety-nine patients (92%) had stage IB1 tumors and 58 (54%) patients had tumors ≤2 cm. The median surgical time was 240 min (range 190-290), the median estimated blood loss was 140 mL (range 50-500) and the transfusion rate was 3.7%. The median length of hospital stay was 2 days (range 1-11). The median follow-up time was 39 months (range 11-83). The global recurrence rate after laparoscopic radical hysterectomy was 15% (16/108). According to tumor size, the recurrence rate was 12% in patients with tumors ≤2 cm (7/58) and 18% in patients with tumors >2 cm (9/50) (OR=0.76; 95% CI 0.26 to 2.22; p=0.62) The 3- and 5-year relapse rate was 17% (95% CI 11% to 27%). The 3- and 5-year disease-free survival was 81% (95% CI 71% to 88%) and 70% (95% CI 43% to 86%), respectively. Overall survival at 3 years was 87% (95% CI 76% to 93%). CONCLUSION: The recurrence rate after laparoscopic radical hysterectomy was 15%, and in tumors ≤2 cm it was 12%. The 3-year disease-free survival was 81%. Given these results our hospital has changed the approach to open radical hysterectomy.

RESUMO

Objective: Real-world data for patients with endometrial cancer (EC) are limited, particularly in Latin America. We present treatment pattern findings from ECHOS-A - Endometrial Cancer Health Outcomes Study in Argentina. Materials and methods: A retrospective study using clinical data from privately insured patients with EC diagnosed from 2010 to 2019. Index (diagnosis proxy) was first date of an EC-related health term or treatment. Demographics, clinical characteristics, and FIGO staging were described. Disease progression and survival were assessed until study end, loss to follow-up, or death. Results: Of 805 patients with EC, 77.4 % (n = 623/805) received any treatment and 22.6 % (n = 182/805) received none. Among those treated, 31.8 % (n = 198/623) had first-line (1L) systemic therapy, and 45.5 % (n = 90/198) proceeded to second-line (2L) therapy. Mean follow-up was 33.6 (SD 31.8) months. Of those receiving any treatment, 87.3 % (n = 544/623) had FIGO stage data (I, 62.9 %; II, 18.6 %; III, 13.6 %; IV, 5.0 %). Treatment by class in 1L and 2L, respectively, were platinum chemotherapy, 73.7 %, 36.7 %; non-platinum chemotherapy, 73.7 %, 62.2 %; immunotherapy, 1.0 %, 11.1 %; hormone therapy, 17.7 %, 26.7 %. Carboplatin/paclitaxel was the most frequent 1L (52.5 %) and 2L (14.4 %) regimen. Mean time to progression was 14.1 (SD 16.3) and 8.8 (SD 8.3) months in 1L and 2L, respectively. Adjusted 1- to 5-year risk of progression/death was 46.5-77.5 % and 65.0-86.2 % in 1L and 2L, respectively. Conclusions: Approximately one-quarter of patients with EC received no treatment, and approximately two-thirds were not treated with 1L systemic therapy. Efforts to better understand the reasons for these treatment patterns are crucial for improving patient outcomes.

RESUMO

AIM: The aim of this study was to assess whether the use of sentinel lymph node (SLN) in addition to lymphadenectomy was associated with survival benefit in patients with early-stage cervical cancer. METHODS: International, multicenter, retrospective study. INCLUSION CRITERIA: cervical cancer treated between 01/2007 and 12/2016 by surgery only; squamous cell carcinoma, adenocarcinoma, adenosquamous carcinoma, FIGO 2009 stage IB1-IIA2, negative surgical margins, and laparotomy approach. Patients undergoing neo-adjuvant and/or adjuvant treatment and/or with positive para-aortic lymph nodes, were excluded. Women with positive pelvic nodes who refused adjuvant treatment, were included. Lymph node assessment was performed by SLN (with ultrastaging protocol) plus pelvic lymphadenectomy ('SLN' group) or pelvic lymphadenectomy alone ('non-SLN' group). RESULTS: 1083 patients were included: 300 (27.7 %) in SLN and 783 (72.3 %) in non-SLN group. 77 (7.1 %) patients had recurrence (N = 11, 3.7 % SLN versus N = 66, 8.4 % non-SLN, p = 0.005) and 34 (3.1 %) (N = 4, 1.3 % SLN versus N = 30, 3.8 % non-SLN, p = 0.033) died. SLN group had better 5-year disease-free survival (DFS) (96.0 %,95 %CI:93.5-98.5 versus 92.0 %,95 %CI:90.0-94.0; p = 0.024). No 5-year overall survival (OS) difference was shown (98.4 %,95 %CI:96.8-99.9 versus 96.8 %,95 %CI:95.4-98.2; p = 0.160). SLN biopsy and lower stage were independent factors associated with improved DFS (HR:0.505,95 %CI:0.266-0.959, p = 0.037 and HR:2.703,95 %CI:1.389-5.261, p = 0.003, respectively). Incidence of pelvic central recurrences was higher in the non-SLN group (1.7 % versus 4.5 %, p = 0.039). CONCLUSION: Adding SLN biopsy to pelvic lymphadenectomy was associated with lower recurrence and death rate and improved 5-year DFS. This might be explained by the lower rate of missed nodal metastasis thanks to the use of SLN ultrastaging. SLN biopsy should be recommended in patients with early-stage cervical cancer.

RESUMO

OBJECTIVE: Trocar site herniation is a recognized complication of minimally invasive surgery, but published data on trocar site herniation after robotic surgery are scarce. We sought to determine the incidence of trocar site herniation in women undergoing robotic surgery for gynecologic disease. METHODS: A retrospective review of robotic surgeries performed from January 1, 2006, through December 31, 2012, was conducted. Postoperative trocar site herniations were identified, along with time to presentation, location of herniation, and management. Patients were excluded if surgery was converted to laparotomy or traditional laparoscopy. The Wilcoxon rank-sum test was used to compare patients with and without herniation with respect to continuous variables, and Fisher's exact test was used to compare these 2 groups with respect to categorical variables. RESULTS: The study included 500 patients, 3 of whom experienced herniation at a single trocar site. The patients with and without herniation did not differ with respect to age, body mass index, smoking status, medical comorbidities, operating time, or estimated blood loss. All 3 herniations occurred at 12-mm trocar sites. Two herniations occurred at assistant port sites, and 1 occurred at the umbilical camera port site. The median time to herniation was 21 days (range, 8-38 days). One patient required immediate surgical intervention; the other 2 patients had conservative management. CONCLUSIONS: Trocar site herniation is a rare complication following robotic surgery. The most important risk factor for trocar site herniation appears to be larger trocar size, as all herniations occurred at 12-mm port sites.

RESUMO

INTRODUCTION: The removal of the uterus, (hysterectomy), is the most frequent surgery in gynecology. In Argentina there are few publications on the perioperative results of this type of procedure, and even less on minimally invasive hysterectomy. The objective of this study was to determine the rate of perioperative complications in patients with total laparoscopic hysterectomy performed at Hospital Italiano de Buenos Aires, from January 7, 2010 to December 22, 2020. METHODS: retrospective cohort study where electronic medical records were reviewed. Intrasurgical and postoperative complications were evaluated using the validated Clavien-Dindo's classification. RESULTS: 1014 patients were included. The rate of intra-surgical complications was 4.5%. In respect to postoperative complications, there was found a rate of 16.6% (n=168), being 12.3% (n=125) Clavien-Dindo = 2, and 4.2% (n=43) Clavien-Dindo = 3. In a multivariable analysis that adjusted for uterine weight > 170g, age, body mass index, and more than two previous abdominal surgeries, an association was found between uterine weight >170g and postoperative complications OR 1.49, 95% CI 1.04- 2.14, p=0.03. DISCUSSION: When evaluating the percentage of minor and major complications, our findings are within the acceptable parameters for performing this type of surgery, even though the evaluation was carried out in an educational setting.


Introducción: La extirpación del útero, (histerectomía) es la cirugía más frecuente en ginecología. En Argentina existen pocas publicaciones sobre los resultados perioperatorios de este tipo de procedimiento, y menos aún sobre histerectomía mínimamente invasiva. El objetivo de este estudio fue determinar la tasa de complicaciones perioperatorias en pacientes con histerectomía total laparoscópica realizada en el Hospital Italiano de Buenos Aires, desde el 7 de enero de 2010 al 22 de diciembre de 2020. Métodos: estudio de cohorte retrospectivo donde se revisaron las historias clínicas electrónicas de pacientes sometidas a una histerectomía laparoscópica en el período mencionado. Se evaluaron las complicaciones intraquirúrgicas y postoperatorias utilizando la clasificación validada de Clavien-Dindo. Resultados: Se incluyeron 1014 pacientes. La tasa de complicaciones intraquirúrgicas fue de 4.5%. Se halló una tasa de complicaciones postoperatorias de 16.6% (n=168), siendo 12.3% (n=125) Clavien-Dindo = 2, y 4.2% (n=43) Clavien-Dindo = 3. En el análisis multivariable que se ajustó por peso uterino >170g, edad, índice de masa corporal y más de dos cirugías abdominales previas, se encontró asociación entre peso uterino > 170 g y complicaciones postoperatorias, OR 1.49, IC 95% 1.04-2.14, p = 0.03. Discusión: Al evaluar el porcentaje de complicaciones menores y mayores, nuestros números se encuentran dentro de los parámetros aceptables para realizar este tipo de cirugía, más aún, considerando que la evaluación se realizó en un ámbito educativo.

RESUMO

Objective: To report the surgical, oncological, and obstetrical outcomes of the different surgical techniques used for the fertility-sparing treatment of patients with early-stage cervical cancer. Methods: We retrospectively analyzed all fertility-sparing procedures performed between 2004 and 2020. The study included patients desiring to preserve fertility who had squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinoma histology, all grades, and FIGO 2009 stage IA2-IB1 tumors. Results: 48 patients met the inclusion criteria. Eight patients (16.7%) had stage IA2, and 40 (83.3%) had stage IB1 tumors. Conization with pelvic lymph node assessment was performed in 5 (10.4%) patients, an open radical trachelectomy in 21 (43.8%), and a laparoscopic radical trachelectomy in 22 (45.8%). No major intraoperative complications were registered. Two patients required surgery due to an early postoperative complication. Late postoperative complications were seen in 15 patients (31.2%), with cervical stenosis being the most frequent (60%). The rate of DFS at 2 and 5 years was 89% (95% CI, 76-95%), and the 5- year OS was 96% (95% CI, 83-98%). Univariate analysis demonstrated a relationship between tumor size and recurrence, but not for other prognostic tumor factors or surgical approach. One patient (4.8%) developed recurrent disease in the open radical trachelectomy group, and five (22.7%) in the laparoscopic radical trachelectomy group. The pregnancy rate was 41.4%, and the live birth rate 88.2%. Conclusion: Fertility-sparing treatment for patients with early-stage cervical cancer is ever-evolving. This study adds information to the literature about the outcomes of these quite uncommon procedures, and allows a critical analysis of many of the topics which are under discussion.
