RESUMEN

BACKGROUND: Ovarian cancer is a challenging disease to diagnose and treat effectively with five-year survival rates below 50%. Previous patient experience research in high-income countries highlighted common challenges and opportunities to improve survival and quality of life for women affected by ovarian cancer. However, no comparable data exist for low-and middle-income countries, where 70% of women with the disease live. This study aims to address this evidence gap. METHODS: This is an observational multi-country study set in low- and middle-income countries. We aim to recruit over 2000 women diagnosed with ovarian cancer across multiple hospitals in 24 countries in Asia, Africa and South America. Country sample sizes have been calculated (n = 70-96 participants /country), taking account of varying national five-year disease prevalence rates. Women within five years of their diagnosis, who are in contact with participating hospitals, are invited to take part in the study. A questionnaire has been adapted from a tool previously used in high-income countries. It comprises 57 multiple choice and two open-ended questions designed to collect information on demographics, women's knowledge of ovarian cancer, route to diagnosis, access to treatments, surgery and genetic testing, support needs, the impact of the disease on women and their families, and their priorities for action. The questionnaire has been designed in English, translated into local languages and tested according to local ethics requirements. Questionnaires will be administered by a trained member of the clinical team. CONCLUSION: This study will inform further research, advocacy, and action in low- and middle-income countries based on tailored approaches to the national, regional and global challenges and opportunities. In addition, participating countries can choose to repeat the study to track progress and the protocol can be adapted for other countries and other diseases.

RESUMEN

OBJECTIVE: To assess the incidence of peritoneal carcinomatosis in patients undergoing minimally invasive or open radical hysterectomy for cervical cancer. METHODS: The MEDLINE (accessed through Ovid), Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Clinical Trials, and Scopus databases were searched for articles published from inception up to April 2022. Articles published in English were considered. The included studies reported on patients with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IA-IIA squamous cell carcinoma, adenocarcinoma, and/or adenosquamous carcinoma of the cervix who underwent primary surgery. Studies had to report at least one case of peritoneal carcinomatosis as a recurrence pattern, and only studies comparing recurrence after minimally invasive surgery versus open surgery were considered. Variables of interest were manually extracted into a standardized electronic database. This study was registered in PROSPERO (CRD42022325068). RESULTS: The initial search identified 518 articles. After the removal of the duplicate entries from the initial search, two authors independently reviewed the titles and abstracts of the remaining 453 articles. Finally, 78 articles were selected for full-text evaluation; 22 articles (a total of 7626 patients) were included in the analysis-one randomized controlled trial and 21 observational retrospective studies. The most common histology was squamous cell carcinoma in 60.9%, and the tumor size was <4 cm in 92.8% of patients. Peritoneal carcinomatosis pattern represented 22.2% of recurrences in the minimally invasive surgery approach versus 8.8% in open surgery, accounting for 15.5% of all recurrences. The meta-analysis of observational studies revealed a statistically significant higher risk of peritoneal carcinomatosis after minimally invasive surgery (OR 1.90, 95% CI 1.32 to 2.74, p<0.05). CONCLUSION: Minimally invasive surgery is associated with a statistically significant higher risk of peritoneal carcinomatosis after radical hysterectomy for cervical cancer compared with open surgery.

RESUMEN

BACKGROUND: Minimally invasive radical trachelectomy has emerged as an alternative to open radical hysterectomy for patients with early-stage cervical cancer desiring future fertility. Recent data suggest worse oncologic outcomes after minimally invasive radical hysterectomy than after open radical hysterectomy in stage I cervical cancer. OBJECTIVE: We aimed to compare 4.5-year disease-free survival after open vs minimally invasive radical trachelectomy. STUDY DESIGN: This was a collaborative, international retrospective study (International Radical Trachelectomy Assessment Study) of patients treated during 2005-2017 at 18 centers in 12 countries. Eligible patients had squamous carcinoma, adenocarcinoma, or adenosquamous carcinoma; had a preoperative tumor size of ≤2 cm; and underwent open or minimally invasive (robotic or laparoscopic) radical trachelectomy with nodal assessment (pelvic lymphadenectomy and/or sentinel lymph node biopsy). The exclusion criteria included neoadjuvant chemotherapy or preoperative pelvic radiotherapy, previous lymphadenectomy or pelvic retroperitoneal surgery, pregnancy, stage IA1 disease with lymphovascular space invasion, aborted trachelectomy (conversion to radical hysterectomy), or vaginal approach. Surgical approach, indication, and adjuvant therapy regimen were at the discretion of the treating institution. A total of 715 patients were entered into the study database. However, 69 patients were excluded, leaving 646 in the analysis. Endpoints were the 4.5-year disease-free survival rate (primary), 4.5-year overall survival rate (secondary), and recurrence rate (secondary). Kaplan-Meier methods were used to estimate disease-free survival and overall survival. A post hoc weighted analysis was performed, comparing the recurrence rates between surgical approaches, with open surgery being considered as standard and minimally invasive surgery as experimental. RESULTS: Of 646 patients, 358 underwent open surgery, and 288 underwent minimally invasive surgery. The median (range) patient age was 32 (20-42) years for open surgery vs 31 (18-45) years for minimally invasive surgery (P=.11). Median (range) pathologic tumor size was 15 (0-31) mm for open surgery and 12 (0.8-40) mm for minimally invasive surgery (P=.33). The rates of pelvic nodal involvement were 5.3% (19 of 358 patients) for open surgery and 4.9% (14 of 288 patients) for minimally invasive surgery (P=.81). Median (range) follow-up time was 5.5 (0.20-16.70) years for open surgery and 3.1 years (0.02-11.10) years for minimally invasive surgery (P<.001). At 4.5 years, 17 of 358 patients (4.7%) with open surgery and 18 of 288 patients (6.2%) with minimally invasive surgery had recurrence (P=.40). The 4.5-year disease-free survival rates were 94.3% (95% confidence interval, 91.6-97.0) for open surgery and 91.5% (95% confidence interval, 87.6-95.6) for minimally invasive surgery (log-rank P=.37). Post hoc propensity score analysis of recurrence risk showed no difference between surgical approaches (P=.42). At 4.5 years, there were 6 disease-related deaths (open surgery, 3; minimally invasive surgery, 3) (log-rank P=.49). The 4.5-year overall survival rates were 99.2% (95% confidence interval, 97.6-99.7) for open surgery and 99.0% (95% confidence interval, 79.0-99.8) for minimally invasive surgery. CONCLUSION: The 4.5-year disease-free survival rates did not differ between open radical trachelectomy and minimally invasive radical trachelectomy. However, recurrence rates in each group were low. Ongoing prospective studies of conservative management of early-stage cervical cancer may help guide future management.

RESUMEN

OBJECTIVES: Twitter is the most frequently used social media platform by healthcare practitioners, at medical conferences. This study aimed to analyze Twitter conversations during the virtual International Gynecological Cancer Society 2020 conference to understand the interactions between Twitter users related to the conference. METHODS: Tweets using the hashtag '#IGCS2020' were searched using the Twitter Search Application Programming Interface (API) during the period 10-13 September 2020. NodeXL Pro was used to retrieve data. The Clauset-Newman-Moore cluster algorithm clustered users into different groups or 'clusters' based on how users interacted. RESULTS: There were 2009 registrants for the virtual IGCS 2020 conference. The total number of users within the network was 168, and there were 880 edges connecting users. Five types of edges were identified as follows: 'replies to' (n=18), 'mentions' (n=221), 'mentions in retweets' (n=375), retweets (n=198), and tweets (n=68). The most influential account was that of the IGCS account itself (@IGCSociety). The overall network shape resembled a community where distinct groups formed within the network. Our current analyses demonstrated that less than 10% of the total members interacted on Twitter. CONCLUSION: This study identified the most influential Twitter users within the '#IGCS2020' community. he results also confirmed the community network shape of the #IGCS2020 hashtag and found that the most frequent co-related words were 'ovarian' and 'cancer' (n=39).

RESUMEN

BACKGROUND: Vulvar cancer is a rare disease and despite broad adoption of sentinel lymph node mapping to assess groin metastases, inguino-femoral lymph node dissection still plays a role in the management of this disease. Inguino-femoral lymph node dissection is associated with high morbidity, and limited research exists to guide the best surgical approach. OBJECTIVE: To determine international practice patterns in key aspects of the inguino-femoral lymph node dissection technique and provide data to guide future research. METHODS: A survey addressing six key domains of practice patterns in performing inguino-femoral lymph node dissection was distributed internationally to gynecologic oncology surgeons between April and October 2020. The survey was distributed using the British Gynecological Cancer Society, the Society of Gynecologic Oncology, authors' direct links, the UK Audit and Research in Gynecology Oncology group, and Twitter. RESULTS: A total of 259 responses were received from 18 countries. The majority (236/259, 91.1%) of respondents reported performing a modified oblique incision, routinely dissecting the superficial and deep inguino-femoral lymph nodes (137/185, 74.1%) with sparing of the saphenous vein (227/258, 88%). Most respondents did not routinely use compression dressings/underwear (169/252 (67.1%), used prophylactic antibiotics at the time of surgery only (167/257, 65%), and closed the skin with sutures (192 74.4%). Also, a drain is placed at the time of surgery by 243/259 (93.8%) surgeons, with most practitioners (144/243, 59.3%) waiting for drainage to be less than 30-50 mL in 24 hours before removal; most respondents (66.3%) routinely discharge patients with drain(s) in situ. CONCLUSION: Our study showed that most surgeons perform a modified oblique incision, dissect the superficial and deep inguino-femoral lymph nodes, and spare the saphenous vein when performing groin lymphadenectomy. This survey has demonstrated significant variability in inguino-femoral lymph node dissection in cases of vulvar cancer among gynecologic oncology surgeons internationally.

RESUMEN

BACKGROUND: Neoadjuvant chemotherapy before fertility-sparing surgery is an accepted option for patients with cervical tumors between 2 cm and 4 cm. There is a paucity of data regarding its role in patients with tumors <2 cm. Our objective was to compare the oncological and obstetrical outcomes between patients who underwent neoadjuvant chemotherapy before cervical conization versus upfront cervical conization in patients with cervical cancer with tumors <2 cm. METHODS: We conducted a systematic literature review and searched MEDLINE, EMBASE, and CINAHL (from 1995 to March 2020) using the terms: uterine cervix neoplasms, cervical cancer, fertility-sparing surgery, fertility preservation, conization, cone biopsy, and neoadjuvant chemotherapy. We included manuscripts with information on patients with tumor size <2 cm, lymph node status, follow-up, oncological and obstetrical outcome, and toxicity related to neoadjuvant chemotherapy. We excluded review articles or articles with duplicated patient information. RESULTS: We identified 12 articles, including 579 patients. For final analysis, 261 patients met inclusion criteria. The most common histology was non-squamous cell carcinoma (62%). Median follow-up time was 63.5 (range 7-122) months for the neoadjuvant chemotherapy group and 48 (range 12-184) months for the upfront cervical conization group. There was no difference in either overall survival (neoadjuvant chemotherapy group 100% vs upfront cervical conization 99.7%, p=0.79) or disease-free survival (neoadjuvant chemotherapy 100% vs upfront cervical conization 98.9%, p=0.59) between the groups. Fertility preservation rate was 81.4% versus 99.1% (p<0.001) favoring upfront cervical conization. No statistically significant differences were seen in live birth rate or pregnancy loss. Also, we found that all neoadjuvant chemotherapy patients reported chemotherapy-related toxicity (30.7% grade 3 and 69.2% grade 1-2). CONCLUSIONS: There was no difference in disease-free survival or overall survival between patients who underwent neoadjuvant chemotherapy followed by conization and upfront cervical conization. Patients who underwent upfront cervical conization had a higher fertility preservation rate.

RESUMEN

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.

RESUMEN

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.

RESUMEN

OBJECTIVE: To determine the acceptance rate of treatment alternatives for women with either preinvasive conditions or gynecologic cancers during the COVID-19 pandemic among Latin American gynecological cancer specialists. METHODS: Twelve experts in gynecological cancer designed an electronic survey, according to recommendations from international societies, using an online platform. The survey included 22 questions on five topics: consultation care, preinvasive cervical pathology, and cervical, ovarian, and endometrial cancer. The questionnaire was distributed to 1052 specialists in 14 Latin American countries. A descriptive analysis was carried out using statistical software. RESULTS: A total of 610 responses were received, for an overall response rate of 58.0%. Respondents favored offering teleconsultation as triage for post-cancer treatment follow-up (94.6%), neoadjuvant chemotherapy in advanced stage epithelial ovarian cancer (95.6%), and total hysterectomy with bilateral salpingo-oophorectomy and defining adjuvant treatment with histopathological features in early stage endometrial cancer (85.4%). Other questions showed agreement rates of over 64%, except for review of pathology results in person and use of upfront concurrent chemoradiation for early stage cervical cancer (disagreement 56.4% and 58.9%, respectively). CONCLUSION: Latin American specialists accepted some alternative management strategies for gynecological cancer care during the COVID-19 pandemic, which may reflect the region's particularities. The COVID-19 pandemic led Latin American specialists to accept alternative management strategies for gynecological cancer care, especially regarding surgical decisions.

RESUMEN

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.

RESUMEN

BACKGROUND: Radical trachelectomy is considered a viable option for fertility preservation in patients with low-risk, early-stage cervical cancer. Standard approaches include laparotomy or minimally invasive surgery when performing radical trachelectomy. PRIMARY OBJECTIVE: To compare disease-free survival between patients with FIGO (2009) stage IA2 or IB1 (≤2cm) cervical cancer who underwent open versus minimally invasive (laparoscopic or robotic) radical trachelectomy. STUDY HYPOTHESIS: We hypothesize that minimally invasive radical trachelectomy has similar oncologic outcomes to those of the open approach. STUDY DESIGN: This is a collaborative, multi-institutional, international, retrospective study. Patients who underwent a radical trachelectomy and lymphadenectomy between January 1, 2005 and December 31, 2017 will be included. Institutional review board approval will be required. Each institution will be provided access to a study-specific REDCap (Research Electronic Data Capture) database maintained by MD Anderson Cancer Center and will be responsible for entering patient data. INCLUSION CRITERIA: Patients with squamous, adenocarcinoma, or adenosquamous cervical cancer FIGO (2009) stages IA2 and IB1 (≤2 cm) will be included. Surgery performed by the open approach or minimally invasive approach (laparoscopy or robotics). Tumor size ≤2 cm, by physical examination, ultrasound, MRI, CT, or positron emission tomography (at least one should confirm a tumor size ≤2 cm). Centers must contribute at least 15 cases of radical trachelectomy (open, minimally invasive, or both). EXCLUSION CRITERIA: Prior neoadjuvant chemotherapy or radiotherapy to the pelvis for cervical cancer at any time, prior lymphadenectomy, or pelvic retroperitoneal surgery, pregnant patients, aborted trachelectomy (intra-operative conversion to radical hysterectomy), or vaginal approach. PRIMARY ENDPOINT: The primary endpoint is disease-free survival measured as the time from surgery until recurrence or death due to disease. To evaluate the primary objective, we will compare disease-free survival among patients with FIGO (2009) stage IA2 or IB1 (≤2cm) cervical cancer who underwent open versus minimally invasive radical trachelectomy. SAMPLE SIZE: An estimated 535 patients will be included; 256 open and 279 minimally invasive radical trachelectomy. Previous studies have shown that recurrence rates in the open group range from 3.8% to 7.6%. Assuming that the 4.5-year disease-free survival rate for patients who underwent open surgery is 95.0%, we have 80% power to detect a 0.44 HR using α level 0.10. This corresponds to an 89.0% disease-free survival rate at 4.5 years in the minimally invasive group.
