RESUMO
BACKGROUND AND OBJECTIVES: To compare the immediate operating room (OR), inpatient, and overall costs between three surgical modalities among women with endometrial cancer (EC) and Class III obesity or higher. METHODS: A multicentre prospective observational study examined outcomes of women, with early stage EC, treated surgically. Resource use was collected for OR costs including OR time, equipment, and inpatient costs. Median OR, inpatient, and overall costs across surgical modalities were analyzed using an Independent-Samples Kruskal-Wallis Test among patients with BMI ≥ 40. RESULTS: Out of 520 women, 103 had a BMI ≥ 40. Among women with BMI ≥ 40: median OR costs were $4197.02 for laparotomy, $5524.63 for non-robotic assisted laparoscopy, and $7225.16 for robotic-assisted laparoscopy (p < 0.001) and median inpatient costs were $5584.28 for laparotomy, $3042.07 for non-robotic assisted laparoscopy, and $1794.51 for robotic-assisted laparoscopy (p < 0.001). There were no statistically significant differences in the median overall costs: $10 291.50 for laparotomy, $8412.63 for non-robotic assisted laparoscopy, and $9002.48 for robotic-assisted laparoscopy (p = 0.185). CONCLUSION: There was no difference in overall costs between the three surgical modalities in patient with BMI ≥ 40. Given the similar costs, any form of minimally invasive surgery should be promoted in this population.

Guidelines for the treatment of tubo-ovarian cancer patients beyond third line are lacking. We aimed to evaluate the effect of response in each line on patient's outcome as well as identify variables that predict response for additional line of chemotherapy. A cohort study was performed including all patients with advanced high-grade ovarian cancer. Survival analysis was performed using Kaplan-Meier curves and log-rank tests. Odds ratios and hazard ratios were calculated using multilevel, mixed-effects logistic regression and Cox regression, adjusting for repeated measures within individual patients. Two-hundred thirty-eight patients were included and underwent up to 10 lines of chemotherapy. The median progression-free survival was 15.6 and overall survival (OS) was 55.6 months. Response rates dropped with each additional line and by line 5, most patients (61%) became refractory and only 16% had any type of response (complete 4% or partial 12%). By line 2, whether a patient had partial disease (PR), stable disease (SD) or progressive disease (PD) did not have an effect on the OS. From line 2, whether a patient had PR, SD or PD did not have an effect on chemotherapy-free interval. Number of previous lines and time from previous line were the only variables that significantly correlated with both outcome of patients and response to the next line. In conclusion, time interval from the previous line of chemotherapy is the major clinical factor that predicts beneficial effect of another line of treatment in patients with ovarian cancer.

INTRODUCTION: We compared oncologic and clinical outcomes in patients with advanced ovarian cancer who received dose-dense weekly paclitaxel with 3-weekly carboplatin with those who received standard 3-weekly chemotherapy. MATERIAL AND METHODS: Comparison of all consecutive patients with advanced (International Federation of Gynecology and Obstetrics stages III-IV) ovarian cancer who received a dose-dense protocol between 2010 and 2016 with an immediate historical cohort of consecutive patients who received standard chemotherapy. Patients who received less than three cycles of treatment were excluded. RESULTS: In all, 246 patients were included in the study, of whom 128 received the dose-dense protocol and 118 were treated with the standard Q3-week protocol. Patients in the dose-dense group had significantly better progression-free survival than those receiving the standard protocol (median progression-free survival 22 vs 15 months; log rank = 0.026). The overall survival of patients in the dose-dense group was also better than that of the patients in the standard protocol group; however, this difference was not statistically significant (median overall survival 66 vs 54 months; log rank = 0.185). The dose-dense protocol remained significantly associated with favorable survival outcome in multivariable analysis adjusted for stage, histologic type, cytoreductive results and neoadjuvant chemotherapy. The use of the dose-dense protocol was associated with higher rates of gastrointestinal, dermatologic, neurologic and hematologic side effects. CONCLUSION: Despite the limitations associated with the comparison to a historical cohort, a dose-dense chemotherapy protocol resulted in a significantly improved progression-free survival and the overall survival tended to be better, but this difference did not reach statistical significance compared with the standard chemotherapy protocol, and may be considered as a treatment alternative, albeit with some increased side effects.

OBJECTIVE: To evaluate long-term oncological outcomes and the added value of sentinel lymph node sampling (SLN) compared to pelvic lymph node dissection (LND) in patients with endometrial cancer (EC). METHODS: During the evaluation phase of SLN for EC, we performed LND and SLN and retrospectively compared the oncologic outcome with the immediate non-overlapping historical era during which patients underwent LND. RESULTS: From 2007 to 2010, 193 patients underwent LND and from December 2010 to 2014, 250 patients had SLN mapping with completion LND. Both groups had similar clinical characteristics. During a median follow-up period of 6.9 years, addition of SLN was associated with more favorable oncological outcomes compared to LND with 6-year overall survival (OS) of 90% compared to 81% (p = 0.009), and progression free survival (PFS) of 85% compared to 75% (p = 0.01) respectively. SLN was associated with improved OS (HR 0.5, 95% CI 0.3-0.8, p = 0.004), and PFS (HR 0.6, 95% CI 0.4-0.9, p = 0.03) in a multivariable analysis, adjusted for age, ASA score, stage, grade, non-endometrioid histology, and LVSI. Patients who were staged with SLN were less likely to have a recurrence in the pelvis or lymph node basins compared to patients who underwent LND only (6-year recurrence-free survival 95% vs 90%, p = 0.04). CONCLUSION: Addition of SLN to LND was ultimately associated with improved clinical outcomes compared to LND alone in patients with endometrial cancer undergoing surgical staging, suggesting that the data provided by the analysis of the SLN added relevant clinical information, and improved the decision on adjuvant therapy.

OBJECTIVE: To evaluate the impact of surgical wait times on outcome of patients with grade 3 endometrial cancer. METHODS: All consecutive patients surgically treated for grade 3 endometrial cancer between 2007 and 2015 were included. Patients were divided into two groups based on the time interval between endometrial biopsy and surgery: wait time from biopsy to surgery ≤12 weeks (84 days) vs more than 12 weeks. Survival analyses were conducted using log-rank tests and Cox proportional hazards models. RESULTS: A total of 136 patients with grade 3 endometrial cancer were followed for a median of 5.6 years. Fifty-one women (37.5%) waited more than 12 weeks for surgery. Prolonged surgical wait times were not associated with advanced stage at surgery, positive lymph nodes, increased lymphovascular space invasion, and tumor size (P = .8, P = 1.0, P = .2, P = .9, respectively). In multivariable analysis adjusted for clinical and pathological factors, wait times did not significantly affect disease-specific survival (adjusted hazard ratio [HR]: 1.2, 95% confidence interval [CI], 0.6-2.5, P = .6), overall survival (HR: 1.1, 95% CI, 0.6-2.1, P = .7), or progression-free survival (HR: 0.9, 95% CI, 0.5-1.7, P = .8). CONCLUSION: Prolonged surgical wait time for poorly differentiated endometrial cancer seemed to have a limited impact on clinical outcomes compared to biological factors.

INTRODUCTION: The objective was to assess whether an early response to neoadjuvant chemotherapy in women with advanced ovarian cancer may predict short- and long-term clinical outcome. MATERIAL AND METHODS: This is a retrospective study of all women with stage III-IV tubo-ovarian cancer treated with neoadjuvant chemotherapy at a single center in Montreal between 2003 and 2014. Logistic regression models were used to evaluate the association between cancer antigen 125 (CA-125) levels during neoadjuvant chemotherapy and debulking success. Cox proportional hazard models were used to estimate hazard ratios and their respective 95% CI for death and recurrence. Harrell's concordance indices were calculated to evaluate which variables best predicted the chemotherapy-free interval and overall survival in our population. RESULTS: In all, 105 women were included. Following the first, second, and third cycles of neoadjuvant chemotherapy, CA-125 levels had a median reduction of 43.2%, 85.4%, and 92.9%, respectively, compared with CA-125 levels at diagnosis. As early as the second cycle, CA-125 was associated with overall survival (hazard ratio 1.03, 95% CI 1.01-1.05, per 50 U/mL increment). By the third cycle, CA-125 did not only predict overall survival (hazard ratio 1.04, 95% CI 1.01-1.08), but it predicted overall survival better than the success of debulking surgery (Harrell's concordance index 0.646 vs 0.616). Both absolute CA-125 levels and relative reduction in CA-125 levels after 2 and 3 cycles predicted the chance to achieve complete debulking (P < .05). CONCLUSIONS: Reduction of CA-125 levels during neoadjuvant chemotherapy provides an early predictive tool that strongly correlates with successful cytoreductive surgery and long-term clinical outcome in women with advanced high-grade serous and endometrioid ovarian cancer.

OBJECTIVE: To perform a hypothesis-generating evaluation of patient outcomes following neoadjuvant chemotherapy (NACT) compared with those following primary debulking surgery (PDS) in patients over age 75 with high-grade ovarian cancer. METHODS: This was a retrospective cohort study of consecutive patients aged 75 years and older, with high-grade ovarian cancer. Data were analyzed in SPSS 25.0 using descriptive statistics to characterize groups based on primary treatment modality, Kaplan-Meier survival curves to estimate overall and progression-free survival, and Cox proportional hazards to analyze confounders. RESULTS: Of 429 patients with stages III and IV high-grade ovarian cancer (endometrioid and serous), 71 were aged older than 75 years and met our criteria for inclusion; 58 were treated with NACT while 13 underwent primary debulking. Sixteen patients did not undergo interval debulking following NACT. There were no significant differences in demographic characteristics between the groups. Following NACT, more patients were completely debulked-36.2% versus 21% (P = 0.000)-and had a shorter length of stay (5 vs. 7 d; P = 0.018). Overall survival was similar between the NACT and PDS groups (58.7 vs. 59.7 mo; LR -0.836; P = 0.361) despite lower progression-free survival in the NACT group (25.9 vs. 47.1 mo; P = 0.042; LR 4.31). Both progression-free and overall survival were significantly higher when patients undergoing NACT achieved complete debulking (21.7 and 102.3 mo, respectively) compared with suboptimal debulking (12.03 and 14.2 mo, respectively). CONCLUSION: In this select group older patients with stage III and IV high-grade ovarian cancers, neoadjuvant chemotherapy may be considered without compromising outcomes and contributes to complete debulking.

OBJECTIVE: To assess risk factors for lymph node involvement in patients with endometrial cancer and a body-mass index (BMI) ≥30â¯kg/m2. MATERIALS AND METHODS: A retrospective analysis was performed of obese patients diagnosed with endometrial carcinoma between 2007 and 2015, treated in a single center in Montreal. Preoperative variables evaluated were age, BMI, parity, and preoperative ASA score, grade, CA-125 and histology. Odds ratios (OR) and hazard ratios (HR) and their respective 95% confidence intervals (95%CI) were calculated using multivariable logistic regression and Cox proportional hazard models. RESULTS: The study included 230 women with BMI ≥30, 223 (97.0%) had complete staging. Pelvic lymph node involvement was detected in 26 patients (11.3%). Sentinel node detection and pelvic lymph node dissection decreased with increasing BMI (adjusted OR 0.86, 95%CI 0.76-0.97 and 0.76, 95%CI 0.59-0.96, respectively, per 1â¯kg/m2 increment). Pelvic lymph node involvement was inversely correlated with BMI (adjusted OR 0.88, 95%CI 0.79-0.99) and present in 16/85 (18.8%), 6/56 (10.7%), and 4/82 (4.9%) of patients with a BMI of 30.0-34.9, 35.0-39.9, and ≥40.0â¯kg/m2, respectively. Preoperative CA-125 was associated with lymph node involvement (adjusted OR 2.77, 95%CI 1.62-4.73, per quartile increment). CONCLUSION: Pelvic lymph node dissection might be omitted in selected cases of morbidly obese patients with failed sentinel nodes mapping and a low CA-125.

OBJECTIVE: Sentinel lymph node (SLN) mapping is increasingly being used in the treatment of apparent early-stage endometrial cancer. The aim of this study was to evaluate whether three tracers (blue dye, indocyanine green (ICG), and technetium-99 (Tc99)) performed better than two (ICG and Tc99). STUDY DESIGN: Prospective study of all consecutive patients (n=163) diagnosed with clinical early-stage endometrial cancer from 2015 to 2017. All patients were randomly assigned to receive a mixture of ICG and Tc99 with or without blue dye. Subgroup analysis for detection rates was performed for each group (double versus triple tracer). RESULTS: One hundred and fifty-seven patients met the inclusion criteria. Eighty patients received ICG and Tc99 with unilateral and bilateral SLN detection rates of 97.5% and 81.3%, respectively. Seventy-seven patients received all three tracers with unilateral and bilateral detection rates of 93.5% and 80.5%, respectively. Only one patient in the triple tracer group was detected by blue dye alone. No significant differences were noticed in unilateral or bilateral detection rates between the two groups, nor in the detection of lymph node metastasis. CONCLUSION: The addition of blue dye to ICG and Tc99 did not demonstrate any improvement in SLN detection.

INTRODUCTION: With the rapid uptake of robotic surgery in surgical oncology, its use in the treatment of epithelial ovarian cancers is being evaluated. Complete cytoreduction represents the goal of surgery either at primary cytoreduction or after neoadjuvant chemotherapy in the setting of interval cytoreduction. In selected patients, the extent of disease would enable minimally invasive surgery. The objective of this study was to evaluate the impact of introducing robotic surgery for interval cytoreduction of selected patients with stage III-IV ovarian cancer. METHODS: All patients who underwent surgery from November 2008 to 2014 (concurrent time period when robotic and open surgery were used simultaneously) after receiving neoadjuvant chemotherapy for advanced ovarian cancer (stage III-IV) were compared with all consecutive patients who underwent cytoreductive surgery by laparotomy after neoadjuvant chemotherapy between January 2006 and November 2008. Inclusion criteria included an interval cytoreductive surgery by laparotomy or robotic assistance for stage III-IV non-mucinous epithelial ovarian, fallopian tube, or primary peritoneal cancer. Exclusion criteria included patients treated concurrently for a non-gynecologic cancer, as well as secondary cytoreductive surgeries and diagnostic surgeries without an attempt at tumor reduction. Overall survival, progression-free survival, and peri-operative outcomes were compared for the entire patient cohort with those with advanced ovarian cancer who received neoadjuvant chemotherapy immediately before and after the introduction of robotic surgery. RESULTS: A total of 91 patients were selected to undergo interval cytoreduction either via robotic surgery (n=57) or laparotomy (n=34) after the administration of neoadjuvant chemotherapy. The median age of the cohort was 65 years (range 24-88), 78% had stage III disease, and the median follow-up time was 37 months (5.6-91.4 months). The median survival was 42.8±3.1 months in the period where both robotic surgery and laparotomy were offered compared with 37.9±9.8 months in the time period preceding when only laparotomy was performed (p=0.6). All patients selected to undergo interval robotic cytoreduction following neoadjuvant chemotherapy had a reduction of cancer antigen 125 by at least 80%, resolution of ascites, and CT findings suggesting the potential to achieve optimal interval cytoreduction. All these patients achieved optimal cytoreduction with <1 cm residual disease, including 82% with no residual disease. The median blood loss was 100 mL (mean 135 mL, range 10-1250 mL), and the median hospital stay was 1 day. CONCLUSION: Robotic interval cytoreductive surgery is feasible in well-selected patients. Future studies should aim to define ideal patients for minimally invasive cytoreductive surgery.

OBJECTIVE: In view of the recent controversy concerning the use of minimally invasive radical hysterectomy as primary treatment for early stage cervical cancer, this study compared the survival and perioperative outcomes in a cohort of patients who underwent radical hysterectomy either by laparotomy or by robotics. METHODS: This retrospective study compared all consecutive patients with early stage cervical cancer since the beginning of the Division of Gynecologic Oncology at the Jewish General Hospital in 2003, who underwent robotic radical hysterectomy (nâ¯=â¯74) with a cohort of all consecutive patients from the immediate past who underwent open radical hysterectomy (nâ¯=â¯24) for early stage cervical cancer. All patients were treated at the Jewish General Hospital in Montréal (Canadian Task Force Classification II-2). RESULTS: The median follow-up time for the robotic group was 46 months. During that time, 7% and 17% of patients in the robotic group and the laparotomy group had disease recurrence, respectively (Pâ¯=â¯0.12). Cox multivariate regression showed no statistically significant effect of surgical approach on overall survival (hazard ratio 1.50, Pâ¯=â¯0.63) or on progression-free survival (hazard ratio 0.29, Pâ¯=â¯0.07). Patients in the robotic cohort had significantly shorter median hospital stays (1 day vs. 7 days, P < 0.001), and their overall incidence of postoperative complications was lower (13% vs. 50%, P < 0.001). Median estimated blood loss for robotics was also significantly lower (82 mL vs. 528 mL, P < 0.001). CONCLUSION: Based on the data on a limited number of patients in a Canadian context, robotic radical hysterectomy did not lead to worse oncologic outcomes and was associated with improved short-term surgical outcomes. One might consider the evaluation of more personalized surgical decision making.

OBJECTIVE: This study sought to evaluate the incidence, risk factors, and estimated cost associated with venous thromboembolism (VTE) following robotic surgery for endometrial cancer. METHODS: The study included all consecutive patients with newly diagnosed endometrial cancer who underwent robotic surgery, excluding patients with a previous history of VTE (3%), those taking long-term warfarin (3%), and patients with conversions to laparotomy (3%). The incidence of postoperative symptomatic VTE within 90 days was analyzed. Direct and indirect medical costs were estimated using a linked billing database for standardized, inflation-adjusted costs. RESULTS: A total of 558 cases were identified. Median BMI was 29 kg/m2 (range, 17-85 kg/m2), median operative time was 227 minutes (range, 75-419 minutes), and median blood loss was 30 mL (range, 3-400 mL). All patients received thromboprophylaxis with intraoperative subcutaneous heparin and sequential pneumatic compression devices. Extended postoperative prophylaxis for 28 days was administered to 88 (17.2%) patients with high-risk factors. A total of eight patients (1.6%) developed symptomatic VTE, and all eight were in the group that did not receive extended prophylaxis. The number needed to treat to prevent one VTE was 52.8, with an absolute risk reduction 1.89% (95% CI 0.59% to 3.19%). The average cost for treatment of a VTE was $7653 (range, $4396-$12 211), equivalent to the cost of treating 21 patients with extended prophylaxis ($356 per patient). CONCLUSION: The incidence of VTE in patients with endometrial cancer who underwent robotic-assisted surgery was low (1.6%), and none of the VTEs occurred in the cohort of high-risk patients who received extended thromboprophylaxis.

OBJECTIVE: To evaluate clinical outcome in patients selected to receive neoadjuvant chemotherapy (NACT) compared to primary debulking surgery (PDS). METHODS: Retrospective study including all consecutive patients diagnosed and treated for advanced (stages III-IV) ovarian cancers between the years 2003-2015. RESULTS: 263 women were included in the study, of these, 127 patients were selected to receive NACT and 136 were treated with PDS followed by adjuvant chemotherapy. PDS was associated with longer OS in stage IIIc disease (median OS: 60.2 vs. 48.8months; p-value 0.039) compared with NACT. Patients achieved higher rates of complete cytoreduction in the NACT group compared to the PDS group (65.9% vs. 40.2%; p=0.001). Patients attaining complete cytoreduction after PDS had the best survival, (median OS 106months) followed by those with complete cytoreduction after NACT (median OS 71months), followed by those with residual disease after PDS (median OS 55months). Patients with residual disease following interval debulking after NACT had the worst outcome (median OS 36months). Platinum sensitivity following first line and second line chemotherapy was similar whether patients received neoadjuvant chemotherapy or not. CONCLUSION: PDS was associated with improved outcome. NACT appears to improve survival outcome in patients that would have had residual disease after PDS, and attain complete cytoreduction at the time of interval cytoreduction. This treatment option can be used in selected patients that are not candidates for complete cytoreduction at PDS.

INTRODUCTION: Minimally invasive surgery (MIS) has been associated with diminished postoperative pain and analgesia requirements. The objective of the current study was to evaluate the use of analgesia in the post-operative period following robotic surgery for endometrial cancer. METHODS: All consecutive patients who underwent robotic surgery for the treatment of endometrial cancer were included in this study. The timing, dose, and type of analgesics administered postoperatively were recorded from patients' electronic medical record. Data was compared to a matched historical cohort of patients who underwent laparotomy before the introduction of the robotic program. RESULTS: Only eight patients (2.4%, 5 during the first 25 cases and 3 following mini-laparotomy) received patient-controlled analgesia (PCA) following robotic surgery. Most patients' pain was alleviated by over-the-counter analgesics (acetaminophen, non-steroidal anti-inflammatories). In comparison to laparotomy, patients who underwent robotic surgery required significantly less opioids (71mg vs. 12mg IV morphine, p<0.0001) and non-opioids (4810mg vs. 2151mg acetaminophen, 1892 vs. 377mg ibuprofen, and 1470mg vs. 393mg naproxen; all p<0.0001). CONCLUSION: Patients require less analgesics (opioids and non-opioids) following robotic surgery in comparison to conventional laparotomy, including the elderly and the obese. The diminished pain medication use is associated with some cost savings.

OBJECTIVE: Pilot study to assess the value of weekly paclitaxel plus carboplatin every 3weeks (dose dense regimen, DD) compared to the standard 3-weekly protocol in the adjuvant setting for endometrial cancer. METHODS: Retrospective cohort study comparing consecutive patients with high and intermediate-high risk endometrial cancer, undergoing DD protocol (from 2011 to 2015) to a non-overlapping historical cohort with similar characteristics who received treatment every three weeks (2008-2011). RESULTS: 122 patients with endometrial cancer were included in the study, of these, 61 patients received the dose dense protocol and 61 were treated with the standard 3-weekly protocol. After a median follow-up of 61.6months in the 3-weekly cohort, compared with 41.6months in the DD cohort, 40 progressions were recorded. 29 progressions were observed in women treated in the standard protocol, with a three years progression free survival (PFS) of 57.4%, compared to 11 progressions observed in patients in the DD schedule, with a three years PFS of 79.5% (P=0.03). Patients who were treated with the DD protocol were less likely to have progression events compared to the standard cohort with a hazard ratio of 0.4 on multivariate analysis (CI 95%, 0.2-0.8, P=0.01), had significantly less distant metastases (P=0.01), and had improved overall survival when diagnosed with advanced stage disease (P=0.02). Complaints of musculoskeletal pain were more frequent in the standard cohort (n=17, 27.9%) compared to the dose dense cohort (n=4, 6.6%), P=0.005. CONCLUSION: Preliminary data suggests that dose dense chemotherapy might be a reasonable and superior option for adjuvant treatment of endometrial cancer, compared to standard chemotherapy.

INTRODUCTION: To evaluate the anatomical location of sentinel lymph nodes (SLN) following intra-operative cervical injection in endometrial cancer. METHODS: All consecutive patients with endometrial cancer undergoing sentinel lymph node mapping were included in this prospective study following intra-operative cervical injection of tracers. Areas of SLN detection distribution were mapped. RESULTS: Among 436 patients undergoing SLN mapping, there were 1095 SLNs removed, and 7.9% of these SLNs found in 13.1% of patients, were detected in areas not routinely harvested during a standard lymph node dissection. These included the internal iliac vein, parametrial, and pre-sacral areas. The SLN was the only positive node in 46.1% (15/36) of cases with successful mapping and completion lymphadenectomy, including 3 cases where the sentinel node in the atypical location was the only node with metastatic disease. CONCLUSION: SLN mapping using intra-operative cervical injection is capable to map out areas not typically included in a standard lymphadenectomy. The sentinel node is the most relevant lymph node to analyze and may enable to discover metastatic disease in unusual areas.

OBJECTIVE: To analyze the changes in the composition of the gynecologic oncology inpatient ward following the implementation of a robotic surgery program and its impact on inpatient resource utilization and costs. METHODS: Retrospective review of the medical charts of patients admitted onto the gynecologic oncology ward the year prior to and five years after the implementation of robotics. The following variables were collected: patient characteristics, hospitalization details (reason for admission and length of hospital stay), and resource utilization (number of hospitalization days, consultations, and imaging). RESULTS: Following the introduction of robotic surgery, there were more admissions for elective surgery yet these accounted for only 21% of the inpatient ward in terms of number of hospital days, compared to 36% prior to the robotic program. This coincided with a sharp increase in the overall number of patients operated on by a minimally invasive approach (15% to 76%, p<0.0001). The cost per surgical admission on the inpatient ward decreased by 59% ($9827 vs. $4058) in the robotics era. The robotics program contributed to a ward with higher proportion of patients with complex comorbidities (Charlson≥5: RR 1.06), Stage IV disease (RR 1.30), and recurrent disease (RR 1.99). CONCLUSION: Introduction of robotic surgery allowed for more patients to be treated surgically while simultaneously decreasing inpatient resource use. With more patients with non-surgical oncological issues and greater medical complexity, the gynecologic oncology ward functions more like a medical rather than surgical ward after the introduction of robotics, which has implications for hospital-wide resource planning.

BACKGROUND: Sentinel lymph node (SLN) mapping has emerged as a promising solution to the ongoing debate regarding lymphadenectomy in the initial surgical management of endometrial cancer. Currently, little is known about its possible impact on location of disease recurrence compared to systematic lymphadenectomy. METHODS: In this retrospective study, 472 consecutive patients with endometrial cancer who underwent either SLN mapping (SLN cohort, n=275) or systematic lymphadenectomy (LND cohort, n=197) from sequential, non-overlapping historical time points were compared. Clinical characteristics were extracted from a prospectively gathered electronic database. Both overall and pelvic sidewall recurrence free survival (RFS) were evaluated at 48-month post-operative follow-up. RESULTS: No significant difference in overall RFS could be identified between the cohorts at 48months (HR 0.74, 95% CI 0.43-1.28, p=0.29). However, the SLN cohort had improved pelvic sidewall RFS compared to the LND cohort (HR 0.32, 95% CI 0.14-0.74, p=0.007). The pelvic sidewall recurrences accounted for 30% of recurrences in the SLN cohort (8 out of 26 recurrences) compared to 71.4% in the LND cohort (20 out of 28 recurrences). CONCLUSIONS: SLN mapping may enable more efficient detection of the LNs at greatest risk of metastasis and help to guide adjuvant therapy, which in turn seems to decrease the risk of pelvic sidewall recurrences.

OBJECTIVE: This study aimed to evaluate and compare robot-assisted surgical staging on clinical outcomes, including quality of life and survival, as a function of patient age. METHODS: Evaluation and comparison of perioperative morbidity, survival, and postoperative quality of life after prospective accumulation of clinical information including outcome measures for patients with endometrial cancer during the first 5 years of a robotic program, based on the following 3 age categories: women older than 80 years, women between 70 and 80 years, and women younger than 70 years. RESULTS: All consecutive patients with endometrial cancer undergoing robotic surgery (n = 303) were included, with 197 women younger than 70 years, 75 women between 70 and 80 years, and 31 women older than 80 years. There were significantly more patients with advanced stage (stage II to IV in 17%, 34%, and 35%, P = 0.02) and grade 3 disease (26%, 43%, and 58%, P = 0.002) with increasing age. The perioperative data showed similar grade I or II complications (Clavien-Dindo classification) between the groups, but significantly more grade III and IV complications for women older than 80 years compared with women 80 years or younger (10% vs 1%, P = 0.004). The time needed to resume chore activities was significantly shorter for patients 70 years or older than patients younger than 70 years [8.9 (8.7) vs 18.8 (25.5) days, P = 0.048]. Overall, all patients irrespective of age were highly satisfied with the procedure. There was no difference between young and elderly patients for disease-free survival (P = 0.99). CONCLUSIONS: Patient's age did not influence minor postoperative morbidity or overall satisfaction after robotic assisted surgery for endometrial cancer. Elderly patients had more major postoperative morbidity but resumed activities quicker than younger patients.

OBJECTIVE: Inherent in the care provided to patients with cancer is an important psychosocial element which has been explored scientifically through qualitative research. The purpose of our study was to evaluate the availability of qualitative research in gynaecologic oncology and to measure its integration in gynaecologic oncology practice guidelines. METHODS: We searched Medline, CINHAL, Scopus, and Web of Science databases to identify the availability of qualitative research conducted in the past 20 years on the three most prevalent gynaecologic cancers: endometrial, ovarian, and cervical cancer. National and international practice guidelines on management of gynaecologic cancers were selected using the National Guideline Clearinghouse website, the Society of Obstetricians and Gynaecologists of Canada website, and the Standards and Guidelines Evidence directory of cancer guidelines. Bibliometric analysis was used to determine the frequency of qualitative references cited in these guidelines. RESULTS: One hundred thirteen qualitative research papers on gynaecologic cancers were identified focusing on psychological impacts, social dynamics, and doctor-patient interactions during cancer treatment and recovery. Among the 15 national and international clinical practice guidelines identified on management of gynaecologic cancer, there were a total of 2272 references, and of these only three references citing qualitative research were identified (0.1%) in only one of the 15 practice guidelines. CONCLUSION: Although qualitative research is being carried out in gynaecologic oncology, its integration into clinical practice guidelines is essentially absent. Efforts to narrow the gap between qualitative research and clinical practice are essential in ensuring a comprehensive approach to the treatment of patients with gynaecologic cancer.
Objectif : Les soins offerts aux patientes atteintes d'un cancer comptent une importante composante psychosociale, laquelle a été explorée de façon scientifique par l'intermédiaire de la recherche qualitative. Notre étude avait pour objectif d'évaluer la disponibilité de la recherche qualitative en gynéco-oncologie et d'en mesurer l'intégration aux directives cliniques relevant du domaine de la gynéco-oncologie. Méthodes : Nous avons mené des recherches dans diverses bases de données (Medline, CINHAL, Scopus et Web of Science) en vue de cerner la disponibilité de la recherche qualitative menée au cours des 20 dernières années au sujet des trois cancers gynécologiques les plus prévalents : les cancers de l'endomètre, de l'ovaire et du col utérin. Des directives cliniques nationales et internationales portant sur la prise en charge des cancers gynécologiques ont été sélectionnées au moyen du site Web National Guideline Clearinghouse, du site Web de la Société des obstétriciens et gynécologues du Canada, et du répertoire Standards and Guidelines Evidence de lignes directrices sur le cancer. Une analyse bibliométrique a été utilisée pour déterminer la fréquence des références qualitatives citées dans les directives cliniques en question. Résultats : Nous avons identifié 113 mémoires de recherche qualitative portant sur des cancers gynécologiques qui se centraient sur les effets psychologiques, sur la dynamique sociale et sur les interactions médecin-patiente dans le cadre du traitement anticancéreux et de la récupération. Au sein des 15 directives cliniques nationales et internationales portant sur la prise en charge des cancers gynécologiques que nous avons identifiées, nous avons dénombré un total de 2 272 références; parmi ces dernières, seules trois références citant une recherche qualitative ont été identifiées (0,1 %), et ce, au sein d'une seule directive clinique parmi les 15 qui ont été analysées. Conclusion : Bien que des efforts de recherche qualitative soient menés dans le domaine de la gynéco-oncologie, l'intégration de leurs résultats aux directives cliniques est essentiellement inexistante. La mise en Åuvre de mesures visant à combler l'écart entre la recherche qualitative et la pratique clinique s'avère essentielle pour assurer l'utilisation d'une approche exhaustive envers le traitement des patientes qui présentent un cancer gynécologique.
