- Background: Radical hysterectomy with pelvic lymphadenectomy represents the standard treatment for early-stage cervical cancer. Results from a recent randomized controlled trial demonstrate that minimally invasive surgery is inferior to laparotomy with regards to disease-free and overall survival.Primary Objective: To investigate the oncologic safety of robot-assisted surgery for early-stage cervical cancer as compared with standard laparotomy.Study Hypothesis: Robot-assisted laparoscopic radical hysterectomy is non-inferior to laparotomy in regards to recurrence-free survival with the advantage of fewer post-operative complications and superior patient-reported outcomes.Trial Design: Prospective, multi-institutional, international, open-label randomized clinical trial. Consecutive women with early-stage cervical cancer will be assessed for eligibility and subsequently randomized 1:1 to either robot-assisted laparoscopic surgery or laparotomy. Institutional review board approval will be required from all participating institutions. The trial is coordinated from Karolinska University Hospital, Sweden.Major Inclusion/Exclusion Criteria: Women over 18 with cervical cancer FIGO (2018) stages IB1, IB2, and IIA1 squamous, adenocarcinoma, or adenosquamous will be included. Women are not eligible if they have evidence of metastatic disease, serious co-morbidity, or a secondary invasive neoplasm in the past 5 years.Primary Endpoint: Recurrence-free survival at 5 years between women who underwent robot-assisted laparoscopic surgery versus laparotomy for early-stage cervical cancer.Sample Size: The clinical non-inferiority margin in this study is defined as a 5-year recurrence-free survival not worsened by >7.5%. With an expected recurrence-free survival of 85%, the study needs to observe 127 events with a one-sided level of significance (alpha) of 5% and a power (1-beta) of 80%. With 5 years of recruitment and 3 years of follow-up, the necessary number of events will be reached if the study can recruit a total of 768 patients.Estimated Dates for Completing Accrual and Presenting Results: Trial launch is estimated to be May 2019 and the trial is estimated to close in May 2027 with presentation of data shortly thereafter.

Increasingly better diagnosis and treatment of endometrial cancer : Allt bättre diagnostik och behandling vid endometriecancer
- 2015

In: Läkartidningen. - 0023-7205. ; 112
-
Journal article (peer-reviewed)abstract
- Endometrial cancer is the most common gynecological cancer in developed countries and the observed rise in incidence is mainly caused by life style factors including obesity and diabetes. The management of the disease has undergone major changes in the past 5-10 years. Morphological and genetic studies constitute the basis for the new classification of the disease, and data emerging from the Cancer Genome Atlas suggest that genomic patterns differ within the two types of endometrial cancer. The prognosis seems to be related to occult lymphatic spread but the role of lymphadenectomy is heavily debated. Development of novel biomarkers, sentinel lymph node technique and refined radiological methods may reduce the need of comprehensive staging in the future. The results from the Cancer Genome Atlas suggest that women with endometrial cancer may benefit from »targeted therapies« in the evolving era of personalised medicine.

Pelvic sentinel lymph node biopsy in endometrial cancer- A simplified algorithm based on histology and lymphatic anatomy
- 2020
-
In: International Journal of Gynecological Cancer. - : BMJ. - 1048-891X .- 1525-1438. ; 30:3, s. 339-345
-
Journal article (peer-reviewed)abstract
- Objective: To achieve the full potential of sentinel lymph node (SLN) detection in endometrial cancer, both presumed low- A nd high-risk groups should be included. Perioperative resource use and complications should be minimized. Knowledge on distribution and common anatomical sites for metastatic SLNs may contribute to optimizing the concept while maintaining sensitivity. Proceeding from previous studies, simplified algorithms based on histology and lymphatic anatomy are proposed. Methods: Data on mapping rates and locations of pelvic SLNs (metastatic and non-metastatic) from two previous prospective SLN studies in women with endometrial cancer were retrieved. Cervically injected indocyanine green was used as a tracer and an ipsilateral re-injection was performed in case of non-display of the upper and/or lower paracervical pathways. A systematic surgical algorithm was followed with clearly defined SLNs depicted on an anatomical chart. In high-risk endometrial cancer patients, removal of SLNs was followed by a pelvic and para-aortic lymphadenectomy. Results: 423 study records were analyzed. The bilateral mapping rates of the upper and lower paracervical pathways were 88.9% and 39.7%, respectively. 72% of all SLNs were typically positioned along the upper paracervical pathway (interiliac and/or proximal obturator fossa) and 71 of 75 (94.6%) of pelvic node positive women had at least one metastatic SLN at either of these positions. Women with grade 1-2 endometroid cancers (n=275) had no isolated metastases along the lower paracervical pathway compared with two women with high-risk histologies (n=148). Conclusion: SLNs along the upper paracervical pathway should be identified in all endometrial cancer histological subtypes; removal of nodes at defined typical positions along the upper paracervical pathway may replace a site-specific lymphadenectomy in case of non-mapping despite tracer re-injection. Detection of SLNs along the lower paracervical pathway can be restricted to high-risk histologies and a full pre-sacral lymphadenectomy should be performed in case of non-display.

Oncologic outcomes after Total Mesometrial Resection (TMMR) or treatment according to current international guidelines in FIGO (2009) stages IB1-IIB cervical cancer : an observational cohort study.
- 2024

In: eClinicalMedicine. - 2589-5370. ; 73

Journal article (peer-reviewed)abstract
- BACKGROUND: According to international guidelines, standard treatment (ST) with curative intent in cervical cancer (CC) comprises radical hysterectomy and pelvic lymphadenectomy in early stages (International Federation of Gynecology and Obstetrics (FIGO) 2009 IB1, IIA1), adjuvant chemoradiation is recommended based on risk factors upon final pathology. Definitive chemoradiation is recommended in locally advanced stages (FIGO 2009 IB2, IIA2, IIB). Total mesometrial resection (TMMR) with therapeutic lymph node dissection (tLND) without adjuvant radiation has emerged as a promising treatment. Here we compare oncologic outcome by TMMR + tLND or ST.METHODS: In this observational cohort study, women treated according to international guidelines were identified in the population-based registries from Sweden and women treated with TMMR were identified in the Leipzig Mesometrial Resection (MMR) Study Database (DRKS 0001517) 2011-2020. Relevant clinical and tumour related variables were extracted. Recurrence-free survival (RFS) and overall survival (OS) by ST or TMMR was analysed with log-rank test, cumulative incidence function and proportional hazard regression yielding hazard ratios (HR) with 95% confidence intervals (CI), adjusted for relevant confounders.FINDINGS: Between 2011 and 2020, 1007 women were included in the final analysis. 733 women were treated according to ST and 274 with TMMR. RFS at five years was 77.9% (95% CI 74.3-81.1) and 82.6% (95% CI 77.2-86.9) for the ST and TMMR cohorts respectively (p = 0.053). In early-stage CC, RFS was higher after TMMR as compared to ST, 91.2% vs 81.8% (p = 0.002). In the adjusted analysis, TMMR was associated with a lower hazard of recurrence (HR 0.39; 95% CI 0.22-0.69) and death (HR 0.42; 95% CI 0.21-0.86) compared to ST. The absolute difference in risk of recurrence at 5 years was 9.4% (95% CI 3.2-15.7) in favor of TMMR. In locally advanced CC, no significant differences in RFS or OS was observed.INTERPRETATION: Compared to ST, TMMR without radiation therapy was associated with superior oncologic outcomes in women with early-stage cervical cancer whereas no difference was observed in locally advanced disease. Our findings together with previous evidence suggest that TMMR may be considered the primary option for both early-stage and locally advanced cervical cancer confined to the Müllerian compartment.FUNDING: This study was supported by grants from Centre for Clinical Research Sörmland (Sweden) and Region Stockholm (Sweden).

Journal article (peer-reviewed)abstract
- Advanced-stage ovarian cancer has a poor prognosis; surgical resection with the intent to leave no residual tumour followed by adjuvant chemotherapy is the standard treatment. Local anaesthetics (LA) have anti-inflammatory and analgesic effects. We hypothesised that intraperitoneal LA (IPLA) would lead to improved postoperative recovery, better pain relief, and earlier start of chemotherapy.This was a prospective, randomised, double-blind, placebo-controlled pilot study in 40 women undergoing open abdominal cytoreductive surgery. Patients were randomised to receive either intraperitoneal ropivacaine (Group IPLA) or saline (Group Placebo) perioperatively. Except for study drug, patients were treated similarly. Intraoperatively, ropivacaine 2 mg ml-1 or 0.9% saline was injected thrice intraperitoneally, and after operation via a catheter and analgesic pump into the peritoneal cavity for 72 h. Postoperative pain, time to recovery, home discharge, time to start of chemotherapy, and postoperative complications were recorded.No complications from LA administration were recorded. Pain intensity and rescue analgesic consumption were similar between groups. Time to initiation of chemotherapy was significantly shorter in Group IPLA (median 21 [inter-quartile range 21-29] vs 29 [inter-quartile range 21-40] days; P=0.021). Other parameters including time to home readiness, home discharge and incidence, and complexity of postoperative complications were similar between the groups.Intraperitoneal ropivacaine during and for 72 h after operation after cytoreductive surgery for ovarian cancer is safe and reduces the time interval to initiation of chemotherapy. Larger studies are warranted to confirm these initial findings.NCT02256228.

Pelvic Sentinel lymph node detection in High-Risk Endometrial Cancer (SHREC-trial)—the final step towards a paradigm shift in surgical staging
- 2019
-
In: European Journal of Cancer. - : Elsevier BV. - 0959-8049 .- 1879-0852. ; 116, s. 77-85
-
Journal article (peer-reviewed)abstract
- Study aims: To prospectively assess the diagnostic accuracy of a pelvic sentinel lymph node (SLN) algorithm in high-risk endometrial cancer (HREC). Patients and methods: Consecutive women with presumed FIGO stage I-II HREC underwent robotic surgery at two academic centres by five accredited surgeons. An anatomically based algorithm was adhered to, following cervical injection of indocyanine green (ICG), with reinjection of tracer in case of non-display of predefined lymphatic pathways. After removal of SLNs, a pelvic and infrarenal para-aortic lymphadenectomy was performed. Primary end-point was sensitivity of the SLN-ICG algorithm. Secondary end-points were sensitivity of the overall SLN algorithm (including macroscopically suspect nodes as SLNs), SLN mapping rates and morbidity of the SLN procedure. Results: Two hundred fifty-seven women were analysed; 54 had pelvic lymph node metastases (LNMs), and 52 of those were correctly identified by the SLN-ICG algorithm. In two women (one with false-negative ICG-SLNs and one non-mapped woman), the pelvic LNMs were identified by the overall SLN algorithm. The SLN-ICG algorithm had a sensitivity of 98% (95% confidence interval [CI] 89–100) and a negative predictive value of 99.5% (95% CI 97–100). The sensitivity of the overall SLN algorithm was 100% (95% CI 92–100) and the negative predictive value was 100% (95% CI 98–100). The bilateral mapping rate was 95%. Two women (1%) had isolated para-aortic metastases. No adverse events occurred during the SLN procedure. Conclusion: With a complete sensitivity to detect pelvic LNMs, the described pelvic SLN algorithm can, in the hands of experienced surgeons, exclude overall nodal involvement in 99% and thereby safely replace a full lymphadenectomy in HREC.

Cardiophrenic lymph node resection in advanced ovarian cancer : surgical outcomes, pre- and postoperative imaging
- 2018
-
In: Acta Oncologica. - 0284-186X. ; 57:6, s. 820-824
-
Journal article (peer-reviewed)abstract
- Objective: To evaluate the accuracy of preoperative imaging in the diagnosis of cardiophrenic lymph node (CPLN) metastases and to report perioperative outcomes after resection of CPLN at the time of cytoreductive surgery for advanced epithelial ovarian cancer (EOC). Furthermore, to assess clearance of CPLN by postoperative imaging. Methods: All women with stage IIIC/IV EOC subjected to surgery at our institution from January 2014 to October 2016 were retrospectively identified from a database. Among these, women subjected to CPLN resection during surgery were identified. Pre- and postoperative computed tomography (CT) scans, pathology reports, surgical approach and outcomes were reviewed. Results: One hundred and eighty women with stage IIIC/IV EOC subjected to surgery with curative intent were identified. Twenty-four (13%) of these women underwent CPLN resection. All had CT imaging suggestive of CPLN metastases. 20/24 (83%) had confirmed metastases upon final pathology. CPLN resection was associated with longer operation time, more often advanced upper abdominal surgery and more postoperative complications but there was no difference in days from surgery to initiation of chemotherapy. Postoperative CT was still indicative of CPLN metastases in 13/22 (59%) women despite resection with confirmative pathology. Conclusions: Resection of CPLN metastases is highly feasible without considerable added morbidity. Concern regarding surgical clearance is raised since postoperative imaging was indicative of metastases in the majority of women. The prognostic significance of stage IV disease based exclusively on CPLN metastases is unclear and any survival benefit from the procedure is yet to be determined.

Long-term quality of life after comprehensive surgical staging of high-risk endometrial cancer - results from the RASHEC trial
- 2018
-
In: Acta Oncologica. - : TAYLOR & FRANCIS LTD. - 0284-186X .- 1651-226X. ; 57:12, s. 1671-1676
-
Journal article (peer-reviewed)abstract
- Purpose: The health-related quality of life (HRQoL) outcomes after comprehensive surgical staging including infrarenal paraaortic lymphadenectomy in women with high-risk endometrial cancer (EC) are unknown. Our aim was to investigate the long-term HRQoL between robot-assisted laparoscopic surgery (RALS) and laparotomy (LT). Patients and Methods: A total of 120 women with high-risk stage I-II EC were randomised to RALS or LT for hysterectomy, bilateral salpingoophorectomy, pelvic and infrarenal paraaortic lymphadenectomy in the previously reported Robot-Assisted Surgery for High-Risk Endometrial Cancer trial. The HRQoL was measured with the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-30) and its supplementary questionnaire module for endometrial cancer (QLQ-EN24) questionnaire. Women were assessed before and 12 months after surgery. In addition, the EuroQol Eq5D non-disease specific questionnaire was used for descriptive analysis. Results: There was no difference in the functional scales (including global health status) in the intention to treat analysis, though LT conferred a small clinically important difference (CID) over RALS in cognitive functioning albeit not statistically significant -6 (95% CI-14 to 0, p = .06). LT conferred a significantly better outcome for the nausea and vomiting item though it did not reach a CID, 4 (95% CI 1 to 7, p = .01). In the EORTC-QLQ/QLQ-EN24, no significant differences were observed. Eq5D-3L questionnaire demonstrated a higher proportion of women reporting any extent of mobility impairment 12 months after surgery in the LT arm (p = .03). Conclusion: Overall, laparotomy and robot-assisted surgery conferred similar HRQoL 12 months after comprehensive staging for high-risk EC.

Robot-assisted laparoscopy versus laparotomy for infrarenal paraaortic lymphadenectomy in women with high-risk endometrial cancer: A randomised controlled trial
- 2017
-
In: European Journal of Cancer. - : ELSEVIER SCI LTD. - 0959-8049 .- 1879-0852. ; 79, s. 81-89

Journal article (peer-reviewed)abstract
- Purpose: To investigate if robot-assisted laparoscopic surgery (RALS) was non-inferior to laparotomy (LT) in harvesting infrarenal paraaortic lymph nodes in patients with presumed stage IeII high-risk endometrial cancer. Patients and methods: Patients with histologically proven endometrial cancer, presumed stage IeII with high-risk tumour features, were randomised to hysterectomy, bilateral salpingo-oophorectomy, pelvic and paraaortic lymphadenectomy by either RALS or LT. Primary outcome was paraaortic lymph node count. Secondary outcomes were perioperative events, postoperative complications and total health care cost. Results: Overall 120 patients were randomised and 96 patients were included in the per protocol analysis. Demographic, clinical and tumour characteristics were evenly distributed between groups. Mean (+/- SD) paraaortic lymph node count was 20.9 (+/- 9.6) for RALS and 22 (+/- 11, p = 0.45) for LT. The difference of means was within the non-inferiority margin (-1.6, 95% CI -5.78, 2.57). Mean pelvic node count was lower after RALS (28 +/- 10 versus 22 +/- 8, p amp;lt; 0.001). There was no difference in perioperative complications or readmissions between the groups. Operation time was longer (p amp;lt; 0.001) but total blood loss less (amp;lt;0.001) and hospital stay shorter (amp;lt;0.001) in RALS group than LT group. Health care costs for RALS was significantly lower (mean difference $1568 USD/(sic)1225 Euro, p amp;lt; 0.05). Conclusion: Our results demonstrate non-inferiority in paraaortic lymph node count, comparable complication rates, shorter hospital length and lower total cost for RALS over laparotomy. Generalisability of the latter finding requires a high-volume setting and high surgical proficiency. In women with high-risk endometrial cancer confined to the uterus, RALS is a valid treatment modality. Clinical trials registrations: ClinicalTrials.gov NCT01847703. (C) 2017 Elsevier Ltd.
