A prospective comparison of costs between robotics, laparoscopy, and laparotomy in endometrial cancer among women with Class III obesity or higher.

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.

Prospective cohort study comparing quality of life and sexual health outcomes between women undergoing robotic, laparoscopic and open surgery for endometrial cancer.

OBJECTIVE: To evaluate patient-reported outcomes (PROs) between women treated by laparoscopic, robotic and open approaches for endometrial cancer. METHODS: Prospective cohort study comparing PRO at baseline, short- (1 and 3 weeks) and long-term (12 and 24 weeks) follow-up postoperatively. Quality of life (QOL) measures were the Functional Assessment of Cancer Therapy (FACT-G), EuroQol Five Dimensions (EQ-5D), and Brief Pain Inventory (BPI). Sexual health measures were the Female Sexual Function Index (FSFI) and the Sexual Adjustment and Body Image Scale for Gynecologic Cancer (SABIS-G). RESULTS: 468 eligible patients (laparotomy = 92, laparoscopy = 152, robotic = 224) were recruited. There were no significant differences between the laparoscopy and robotic groups for any PRO (P > 0.05). At short-term follow-up, patients who underwent minimally invasive surgery (robotic or laparoscopy) had significantly higher FACT-G (P < 0.0001) and EQ-5D (P < 0.0001) scores, with less pain (P = 0.02) and improved pain interference (P = 0.0008), than patients undergoing laparotomy. At long-term follow-up, there were sustained improvements in the FACT-G (P = 0.035) and the health state EQ-5D visual analogue scale (P = 0.022). Surgical approach had no impact on sexual health (P > 0.05); however the mean FSFI score for the entire cohort met clinical cut-offs for sexual dysfunction. CONCLUSION: Minimally invasive approaches result in improved QOL beyond the short-term postoperative period, with benefits noted up to 12 weeks after surgery. This prolonged QOL advantage provides further evidence that MIS should be the standard surgical approach for women with early stage endometrial cancer.

No. 230-Initial Evaluation and Referral Guidelines for Management of Pelvic/Ovarian Masses.

OBJECTIVES: To optimize the management of adnexal masses and to assist primary care physicians and gynaecologists determine which patients presenting with an ovarian mass with a significant risk of malignancy should be considered for gynaecologic oncology referral and management. OPTIONS: Laparoscopic evaluation, comprehensive surgical staging for early ovarian cancer, or tumour debulking for advanced stage ovarian cancer. OUTCOMES: To optimize conservative versus operative management of women with possible ovarian malignancy and to optimize the involvement of gynaecologic oncologists in planning and delivery of treatment. EVIDENCE: Published literature was retrieved through searches of PubMed or MEDLINE, CINAHL, and the Cochrane Library, using appropriate controlled vocabulary and key words. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. Grey (unpublished) literature was identified by searching the web sites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies.

No. 344-Opportunistic Salpingectomy and Other Methods of Risk Reduction for Ovarian/Fallopian Tube/Peritoneal Cancer in the General Population.

OBJECTIVE: This guideline reviews the potential benefits of opportunistic salpingectomy to prevent the development of high grade serous cancers (HGSC) of the ovary/fallopian tube/peritoneum based on current evidence supporting the fallopian tube origin of disease. INTENDED USERS: Gynaecologists, obstetricians, family doctors, registered nurses, nurse practitioners, residents, and health care providers. TARGET POPULATION: Adult women (18 and older): OPTIONS: Women considering hysterectomy who wish to retain their ovaries in situ have traditionally also retained their fallopian tubes. In addition, women undergoing permanent surgical sterilization have usually undergone tubal ligation using various methods rather than undergoing surgical removal of the entire fallopian tube. EVIDENCE: For the sections "Evidence Supporting the Hypothesis That HGSC Originates in the Fallopian Tube" and "Current Literature on the Effects and Safety of Opportunistic Salpingectomy," relevant studies were searched in PubMed, Medline, and the Cochrane Systematic Reviews using the following terms, either alone or in combination, with the search limited to English language materials: "high grade serous cancers ovary," "fallopian tube," "peritoneum," "opportunistic salpingectomy," "epithelial ovarian cancers," "origin," "tubal carcinoma in situ," "BRCA mutation," "prophylactic salpingectomy," "inflammation," "clear cell," and "endometrioid." The initial search was performed in March 2015 with a final literature search in March 2016. Relevant evidence was selected for inclusion in the following order: meta-analyses, systematic reviews, guidelines, randomized controlled trials, prospective cohort studies, observational studies, non-systematic reviews, case series, and reports. The total number of studies identified was 458, and 56 studies were included in this review. For the section "Other Factors Influencing the Risk of Developing "Ovarian" Cancers" a general Medline search was carried out using the terms "ovarian neoplasm" and "prevention." The search included papers published from December 2005 to March 2016. Meta-analyses were preferentially selected except where no such review was found. Additional searches for each subheading were also conducted (e.g., "ovarian neoplasm" and "tubal ligation.") Additional significant articles were identified through cross-referencing the identified reviews. For the search for "ovarian neoplasm" and "prevention," 10 meta-analyses were identified. For the search for "ovarian neoplasm" and "tubal ligation," an additional 4 meta-analyses were identified. VALIDATION METHODS: The content and recommendations were drafted and agreed on by the principal authors. The Executive and Board of the Society of Gynecologic Oncology of Canada reviewed the content and submitted comments for consideration, and the Board of the SOGC approved the final draft for publication. The quality of evidence was rated using the criteria described in the Grading of Recommendations Assessment, Development and Evaluation methodology framework (Table 1). The interpretation of strong and weak recommendations is described in Table 2. The summary of findings is available on request. BENEFITS, HARMS, AND/OR COSTS: The addition of opportunistic salpingectomy to a planned hysterectomy or permanent sterilization did not increase rates of hospital readmission (OR 0.91, 95% CI 0.75 to 1.10 and OR 0.8, 95% CI 0.56 to 1.21, respectively) or blood transfusions (OR 0.86, 95% CI 0.67 to 1.10 and OR 0.75, 95% CI 0.32 to 1.73, respectively) but did increase the overall operating time (by 16 minutes and 10 minutes, respectively) in a retrospective review of 43 931 women. The risk of repeat surgery for tubal pathology among women with retained fallopian tubes after hysterectomy was at least doubled (OR 2.13, 95% CI 1.88 to 2.42 in a population-based study of 170 000 women). If general gynaecologists were to consider removal of fallopian tubes at the time of every hysterectomy and sterilization procedure with referral of all patients with HGSC for hereditary cancer counselling and genetic testing, experts project a potential reduction in the rate of HGSC by 40% over the next 20 years. GUIDELINE UPDATE: Evidence will be reviewed 5 years after publication to decide whether all or part of the guideline should be updated. However, if important new evidence is published prior to the 5-year cycle, the review process may be accelerated for a more rapid update of some recommendations. SPONSORS: This guideline was developed with resources funded by the Society of Gynecologic Oncology of Canada and SOGC. SUMMARY STATEMENTS: RECOMMENDATIONS.

No 344-Salpingectomie opportuniste et autres méthodes pour réduire le risque de cancer de l'ovaire, de la trompe de Fallope et du péritoine dans la population générale.

OBJECTIF: La présente directive clinique examine les avantages potentiels de la salpingectomie opportuniste pour prévenir le développement du cancer séreux de grade élevé de l'ovaire, de la trompe de Fallope et du péritoine à la lumière de données probantes actuelles selon lesquelles ce type de cancer prendrait naissance dans la trompe de Fallope. UTILISATEURS CIBLES: Gynécologues, obstétriciens, médecins de famille, infirmières autorisées, infirmières praticiennes, résidents et fournisseurs de soins de santé. POPULATION CIBLE: Femmes adultes (18 ans et plus) : OPTIONS: Les femmes envisageant une hystérectomie et souhaitant conserver leurs ovaires conservent généralement aussi leurs trompes de Fallope. De plus, celles qui subissent une chirurgie de stérilisation permanente subissent habituellement aussi une ligature des trompes selon des méthodes variées plutôt qu'un retrait chirurgical complet des trompes. RéSULTATS: Les sections « Données probantes appuyant l'hypothèse selon laquelle les CSGE prendraient naissance dans la trompe de Fallope ¼ et « Articles récents sur les répercussions et la sûreté de la salpingectomie opportuniste ¼ reposent sur des études pertinentes rédigées en anglais, qui ont été repérées dans PubMed, Medline et la Cochrane Database of Systematic Reviews à l'aide des termes suivants, seuls ou combinés : high grade serous cancers ovary, fallopian tube, peritoneum, opportunistic salpingectomy, epithelial ovarian cancers, origin, tubal carcinoma in situ, BRCA mutation, prophylactic salpingectomy, inflammation, clear cell et endometrioid. La recherche initiale a été menée en mars 2015, et une dernière recherche a été effectuée en mars 2016. Dans l'ordre, les données probantes pertinentes ont été tirées de méta-analyses, de revues de la littérature, de directives, d'essais cliniques randomisés, d'études de cohorte prospectives, d'études d'observation, de revues non systématiques, d'études de série de cas ainsi que de rapports. Au total, 458 études ont été repérées, et 56 ont été retenues pour la présente directive. Pour la section « Autres facteurs influant sur le risque de développer un cancer de ″l'ovaire″ ¼, une recherche générale a été effectuée dans Medline à partir des termes ovarian neoplasm et prevention. Ont été inclus dans cette recherche des articles rédigés entre décembre 2005 et mars 2016. Les méta-analyses ont été privilégiées lorsque possible. Des recherches supplémentaires ont également été menées pour chaque sous-descripteurs (p. ex., ovarian neoplasm et tubal ligation). D'autres articles pertinents ont été ciblés au moyen d'une vérification des références des revues de la littérature retenues. Les termes ovarian neoplasm et prevention ont permis de repérer 10 méta-analyses; les termes ovarian neoplasm et tubal ligation, 4 méta-analyses. MéTHODES DE VALIDATION: Le contenu et les recommandations ont été rédigés et acceptés par les auteurs principaux. La direction et le conseil de la Société de gynéco-oncologie du Canada ont examiné le contenu et soumis des commentaires, puis le Conseil d'administration de la SOGC a approuvé la version finale avant publication. La qualité des données probantes a été évaluée à partir des critères de l'approche GRADE (Grading of Recommendations Assessment, Development and Evaluation) (tableau 1). L'interprétation des recommandations solides et conditionnelles est décrite dans le tableau 2. Le résumé des conclusions peut être fourni sur demande. AVANTAGES, INCONVéNIENTS ET COûTS: L'ajout d'une salpingectomie opportuniste à une hystérectomie ou à une procédure de stérilisation permanente prévue n'a pas entraîné une augmentation des taux de réadmission à l'hôpital (RC : 0,91; IC à 95 % : 0,75-1, 10 et RC : 0,8; IC à 95 % : 0,56-1,21, respectivement) ou de transfusion sanguine (RC : 0,86; IC à 95 % : 0,67-1,10 et RC : 0,75; IC à 95 % : 0,32-1,73, respectivement), mais il a entraîné une hausse de la durée des opérations (de 16 minutes et de 10 minutes, respectivement) selon une étude rétrospective portant sur 43 931 femmes. Le risque de subir des interventions répétées pour une pathologie tubaire chez les femmes ayant conservé leurs trompes de Fallope après une hystérectomie était au moins deux fois plus élevé (RC : 2,13; IC à 95 % : 1,88-2,42, selon une étude fondée sur une population de 170 000 femmes). Selon des experts, si les gynécologues généralistes envisageaient systématiquement de retirer les trompes de Fallope lors d'une hystérectomie ou d'une procédure de stérilisation et d'aiguiller toutes les patientes aux prises avec un CSGE vers une consultation en oncologie génétique et un dépistage génétique, le taux de CSGE pourrait diminuer de 40 % au cours des 20 prochaines années. MISE à JOUR DE DIRECTIVES CLINIQUES: Une revue des données probantes sera menée cinq ans après la publication de la présente directive clinique afin de déterminer si une mise à jour complète ou partielle s'impose. Cependant, si de nouvelles données probantes importantes sont publiées avant la fin du cycle de cinq ans, le processus pourrait être accéléré afin que certaines recommandations soient mises à jour rapidement. PARRAINS: La présente directive clinique a été élaborée à l'aide de ressources financées par la Société de gynéco-oncologie du Canada et la SOGC. DéCLARATIONS SOMMAIRES: RECOMMANDATIONS.

Sentinel lymph node procedure in endometrial cancer: A systematic review and proposal for standardization of future research.

OBJECTIVES: Sentinel lymph node (SLN) procedure could be an attractive solution to the debate on lymphadenectomy in endometrial cancer; however challenges to interpreting the literature include marked heterogeneity across studies, a wide variety of injection techniques and a lack of uniformly accepted definitions for important outcomes. We aim to critically appraise the published literature and streamline terminology and methodology for future studies in this field. METHODS: We conducted a PubMed search and included all original research of endometrial cancer patients having undergone SLN procedure with an n>30. Data collected included injection technique, unilateral, bilateral, and para-aortic detection rates, and ultrastaging results. When different definitions were used for reporting outcomes, we recalculated the original study results according to our proposed definitions. Data was analyzed using descriptive statistics. RESULTS: Seventeen studies met our inclusion criteria. Injection sites were categorized into cervical versus corporeal. Overall detection rates ranged from 60 to 100%; studies with n>100 all had overall detection rates of >80%. Bilateral detection rates were higher with a combination of two injection agents. Para-aortic mapping was most frequent after corporeal injection techniques (39%), and was higher after deep vs. standard cervical injection (17% vs. 2%). The proportion of metastatic lymph nodes diagnosed through ultrastaging was high (around 40%) and ultrastaging of SLN upstaged approximately 5% of patients. Retrospectively applying a surgical algorithm revealed a sensitivity of 95%, a negative predictive value of 99%, and a false negative rate of 5% (with only 9 false negative cases remaining in total). CONCLUSION: Results of SLN research for endometrial cancer are promising. We believe that in future studies, uniform reporting is needed to improve our understanding of the safety and feasibility of SLN in EC. We propose 2 strategies: a checklist of elements to include in future reports and the standardization of key definitions.

Aptima HPV E6/E7 mRNA test is as sensitive as Hybrid Capture 2 Assay but more specific at detecting cervical precancer and cancer.

Detection of human papillomavirus (HPV) E6/E7 oncogene expression may be more predictive of cervical cancer risk than testing for HPV DNA. The Aptima HPV test (Gen-Probe) detects E6/E7 mRNA of 14 oncogenic types. Its clinical performance was compared with that of the Hybrid Capture 2 DNA test (HC2; Qiagen) in women referred for colposcopy and those routinely screened. Aptima was also compared with the PreTect HPV-Proofer E6/E7 mRNA assay (Proofer; Norchip) in the referral population. Cervical specimens collected in PreservCyt (Hologic Inc.) were processed for HPV detection and genotyping with the Linear Array (LA) method (Roche Molecular Diagnostics, Laval, Quebec, Canada). Histology-confirmed high-grade cervical intraepithelial neoplasia (CIN 2) or worse (CIN 2+) served as the disease endpoint. On the basis of 1,418 referral cases (CIN 2+, n = 401), the sensitivity of Aptima was 96.3% (95% confidence interval [CI], 94.4, 98.2), whereas it was 94.3% (95% CI, 92.0, 96.6) for HC2. The specificities were 43.2% (95% CI, 40.2, 46.2) and 38.7% (95% CI, 35.7, 41.7), respectively (P < 0.05). In 1,373 women undergoing routine screening (CIN 2+, n = 7), both Aptima and HC2 showed 100% sensitivity, and the specificities were 88.3% (95% CI, 86.6, 90.0) and 85.3% (95% CI, 83.5, 87.3), respectively (P < 0.05); for women ≥ 30 years of age (n = 845), the specificities were 93.9% (95% CI, 92.3, 95.5) and 92.1% (95% CI, 90.3, 93.9), respectively (P < 0.05). On the basis of 818 referral cases (CIN 2+, n = 235), the sensitivity of Aptima was 94.9% (95% CI, 92.1, 97.7) and that of Proofer was 79.1% (95% CI, 73.9, 84.3), and the specificities were 45.8% (95% CI, 41.8, 49.8) and 75.1% (95% CI, 71.6, 78.6), respectively (P < 0.05). Both Aptima and Proofer showed a higher degree of agreement with LA genotyping than HC2. In conclusion, the Aptima test is as sensitive as HC2 but more specific for detecting CIN 2+ and can serve as a reliable test for both primary cervical cancer screening and the triage of borderline cytological abnormalities.

The acceptability of HPV vaccination among women attending the University of Saskatchewan Student Health Services.

OBJECTIVE: Women attending the University of Saskatchewan Student Health Services are being offered human papillomavirus (HPV) vaccination but are not filling their prescriptions. We sought to identify gaps in knowledge of the link between HPV infection, cervical dysplasia, and cervical cancer among women attending the Student Health Services, and to identify barriers to HPV vaccination among this cohort of women. METHODS: Women attending the University of Saskatchewan Student Health Services for any reason were invited to complete an 18-question survey. The survey included questions regarding knowledge of the purpose of Pap smears, the role of HPV infection in cervical dysplasia and cancer, and HPV vaccination. The questions were designed to elicit both quantitative and qualitative data. Data analysis included basic descriptive analysis and summarization of qualitative data. RESULTS: Four hundred surveys were distributed, and 371 (91%) were returned. Eighty-two percent of participants were aware of the HPV vaccine, and 40% ranked their knowledge of HPV as good or very good; however, only 6% correctly answered questions about methods of preventing HPV infection. Participants identified cost (62%), concerns over adverse effects (43%), and lack of knowledge (36%) as barriers to undergoing vaccination. Comments about the HPV vaccine reflected frustration with cost and concerns about adverse effects. When participants were asked if they would undergo vaccination if it were free, 60% responded "yes," 31% responded "maybe," and 8% responded "no." CONCLUSION: The young women in our survey had significant gaps in knowledge of HPV infection and prevention, and educational programs must be structured to address these deficits. Institutions promoting vaccination must deal with the barriers of cost and fear of adverse effects.

Clinical performance of the PreTect HPV-Proofer E6/E7 mRNA assay in comparison with that of the Hybrid Capture 2 test for identification of women at risk of cervical cancer.

Human papillomavirus (HPV) DNA testing has a higher clinical sensitivity than cytology for the detection of high-grade cervical intraepithelial neoplasia or worse (CIN 2+). However, an improvement in specificity would be desirable. As malignant transformation is induced by HPV E6/E7 oncogenes, detection of E6/E7 oncogene activity may improve specificity and be more predictive of cervical cancer risk. The PreTect HPV-Proofer assay (Proofer; Norchip) detects E6/E7 mRNA transcripts from HPV types 16, 18, 31, 33, and 45 with simultaneous genotype-specific identification. The clinical performance of this assay was assessed in a cross-sectional study of women referred for colposcopy in comparison with the Hybrid Capture 2 (HC2; Qiagen) test, which detects DNA of 13 high-risk oncogenic HPV types collectively. Cervical specimens were collected in PreservCyt, and cytology was performed using the ThinPrep method (Hologic). The samples were processed for HPV detection with Proofer and HC2 and genotyping with the Linear Array method (Roche Molecular Systems). Histology-confirmed CIN 2+ served as the disease endpoint to assess the clinical performance of the tests. A total of 1,551 women were studied, and of these, 402 (25.9%) were diagnosed with CIN 2+ on histology. The Proofer assay showed a sensitivity of 78.1% (95% confidence interval [CI], 74.1 to 82.1) versus 95.8% (95% CI, 93.8 to 97.8) for HC2 (P < 0.05) and a specificity of 75.5% (95% CI, 73.0 to 78.0) versus 39.6% (95% CI, 36.8 to 42.4), respectively (P < 0.05). The lower sensitivity and higher specificity of Proofer for detection of CIN 2+ can be attributed to the fact that this test detects the expression of E6/E7 genes beyond a threshold from a limited number of oncogenic HPV types. In conclusion, Proofer is more specific than HC2 in identifying women with CIN 2+ but has a lower sensitivity.

Teaching cervical cancer surgery in low- or middle-resource countries.

BACKGROUND: With the widespread implementation of screening programs internationally, there will be an increase in early stage cervical cancer cases. In response to this, the Ministry of Health in each country will need to plan strategies to provide care such as radical surgery or radiation for this potentially curable group of women. METHODS: The Gynaecologic Oncologists of Canada created a teaching module to intensively train a small number of locally identified gynecologists to perform radical hysterectomy and pelvic lymphadenectomy. The process was based on adult learning principles; it involved a Canadian gynecologic oncologist working in the low- or middle-resource country with the gynecologists and problem-solving local issues in health care delivery. RESULTS: The teaching process included a pretest and a posttest on the basis of the objectives of the module. There were 7 modules including preoperative evaluation of the patient, cone biopsy, radical hysterectomy, pelvic lymphadenectomy, ureteric injury, vascular injury, and follow-up after surgery. Each module was divided into background information, techniques, and complications. There were video clips imbedded in the modules. After the educational modules had been reviewed, the learners were walked through the surgical procedures repeatedly including a detailed assessment of performance after each case. Participants had the opportunity to provide feedback on the training program. The module was reviewed in Mongolia and implemented in Kenya. CONCLUSIONS: In low- and middle-resource countries where there is an urgent need to provide a curative surgical option for the management of early cervical cancer, a focused high-intensity curriculum delivered by a trained surgeon can translate into immediate change in clinical and surgical practice.

Initial evaluation and referral guidelines for management of pelvic/ovarian masses.

OBJECTIVES: To optimize the management of adnexal masses and to assist primary care physicians and gynaecologists determine which patients presenting with an ovarian mass with a significant risk of malignancy should be considered for gynaecologic oncology referral and management. OPTIONS: Laparoscopic evaluation, comprehensive surgical staging for early ovarian cancer, or tumour debulking for advanced stage ovarian cancer. OUTCOMES: To optimize conservative versus operative management of women with possible ovarian malignancy and to optimize the involvement of gynaecologic oncologists in planning and delivery of treatment. EVIDENCE: Published literature was retrieved through searches of PubMed or MEDLINE, CINAHL, and the Cochrane Library, using appropriate controlled vocabulary and key words. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. Grey (unpublished) literature was identified by searching the web sites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. RECOMMENDATIONS: 1. Primary care physicians and gynaecologists should always consider the possibility of an underlying ovarian cancer in patients in any age group who present with an adnexal or ovarian mass. (II-2B) 2. Appropriate workup of a perimenopausal or postmenopausal woman presenting with an adnexal mass should include evaluation of symptoms and signs suggestive of malignancy, such as persistent pelvic/abdominal pain, urinary urgency/frequency, increased abdominal size/bloating, and difficulty eating. In addition, CA125 measurement should be considered. (II-2B) 3. Transvaginal or transabdominal ultrasound examination is recommended as part of the initial workup of a complex adnexal/ovarian mass. (II-2B) 4. Ultrasound reports should be standardized to include size and unilateral/bilateral location of the adnexal mass and its possible origin, thickness of septations, presence of excrescences and internal solid components, vascular flow distribution pattern, and presence or absence of ascites. This information is essential for calculating the risk of malignancy index II score to identify pelvic mass with high malignant potential. (IIIC) 5. Patients deemed to have a high risk of an underlying malignancy should be reviewed in consultation with a gynaecologic oncologist for assessment and optimal surgical management. (II-2B).

The use of transrectal ultrasound to biopsy pelvic masses in women.

OBJECTIVES: The goal of this study was to review our experience with transrectal ultrasound (TRUS)-guided biopsies in women with a pelvic mass, with respect to obtaining an adequate sample, the influence of biopsy results on patient management, and patient tolerance. STUDY METHODS: We conducted a chart review of all women at the Princess Margaret Hospital (PMH) that had been clinically referred for TRUS-guided biopsies of a pelvic mass. Data collected included patient age, previous type of malignancy, size and location of lesion being biopsied, postbiopsy diagnosis, and subsequent management. Statistics were purely descriptive. RESULTS: Eight women have had this procedure at PMH. The smallest size of lesion biopsied was 1.7 x 1.4 x 2.3 cm. In all eight women, the tissue obtained was adequate for the determination of a histological diagnosis and subsequently influenced patient management. The procedure was well tolerated and there were no complications. CONCLUSION: TRUS-guided biopsy of a pelvic mass is a feasible method of establishing a pathological diagnosis. In this small series of patients, it was found to be accurate, well tolerated, and useful in guiding patient management. In selected patients, the TRUS biopsy provides a useful alternative to transabdominal and transvaginal biopsy.
