Tumor interferon signaling and suppressive myeloid cells are associated with CAR T-cell failure in large B-cell lymphoma.

Axicabtagene ciloleucel (axi-cel) is a chimeric antigen receptor (CAR) T-cell therapy for relapsed or refractory large B-cell lymphoma (LBCL). This study evaluated whether immune dysregulation, present before CAR T-cell therapy, was associated with treatment failure. Tumor expression of interferon (IFN) signaling, high blood levels of monocytic myeloid-derived suppressor cells (M-MDSCs), and high blood interleukin-6 and ferritin levels were each associated with a lack of durable response. Similar to other cancers, we found that in LBCL tumors, IFN signaling is associated with the expression of multiple checkpoint ligands, including programmed cell death-ligand 1, and these were higher in patients who lacked durable responses to CAR-T therapy. Moreover, tumor IFN signaling and blood M-MDSCs associated with decreased axi-cel expansion. Finally, patients with high tumor burden had higher immune dysregulation with increased serum inflammatory markers and tumor IFN signaling. These data support that immune dysregulation in LBCL promotes axi-cel resistance via multiple mechanistic programs: insufficient axi-cel expansion associated with both circulating M-MDSC and tumor IFN signaling, which also gives rise to expression of immune checkpoint ligands.

The Risk of Postoperative Infectious Complications Following Massive Intraoperative Blood Loss During Gynaecologic Laparotomy: Retrospective Cohort Study.

PURPOSE: To determine whether massive intraoperative blood loss (MIBL) was independently associated with postoperative infectious complications after gynaecologic laparotomy. METHODS: We conducted a retrospective cohort study of patients undergoing gynaecologic laparotomy who were exposed or not exposed to MIBL. The outcome of interest was composite postoperative febrile morbidity. Multiple logistic regression was used to determine the association between exposure and outcome while controlling for measured covariates. RESULTS: The primary outcome was identified to have occurred in 48% (144 of 298) of surgeries with MIBL compared with 12% (51 of 413) of surgeries without MIBL (P < 0.0001). MIBL was found to be strongly and independently associated with primary outcome (adjusted odds ratio 7.04; 95% confidence interval 4.62-10.74; P < 0.0001) after adjusting for age, body mass index, diabetes, immunosuppression, type of procedure, incision type, drains left in situ, and bowel complications. CONCLUSION: MIBL is strongly and independently associated with postoperative febrile morbidity after gynaecologic laparotomy.

Guideline No. 408: Management of Gestational Trophoblastic Diseases.

OBJECTIVE: This guideline reviews the clinical evaluation and management of gestational trophoblastic diseases, including surgical and medical management of benign, premalignant, and malignant entities. The objective of this guideline is to assist health care providers in promptly diagnosing gestational trophoblastic diseases, to standardize treatment and follow-up, and to ensure early specialized care of patients with malignant or metastatic disease. INTENDED USERS: General gynaecologists, obstetricians, family physicians, midwives, emergency department physicians, anaesthesiologists, radiologists, pathologists, registered nurses, nurse practitioners, residents, gynaecologic oncologists, medical oncologists, radiation oncologists, surgeons, general practitioners in oncology, oncology nurses, pharmacists, physician assistants, and other health care providers who treat patients with gestational trophoblastic diseases. This guideline is also intended to provide information for interested parties who provide follow-up care for these patients following treatment. TARGET POPULATION: Women of reproductive age with gestational trophoblastic diseases. OPTIONS: Women diagnosed with a gestational trophoblastic disease should be referred to a gynaecologist for initial evaluation and consideration for primary surgery (uterine evacuation or hysterectomy) and follow-up. Women diagnosed with gestational trophoblastic neoplasia should be referred to a gynaecologic oncologist for staging, risk scoring, and consideration for primary surgery or systemic therapy (single- or multi-agent chemotherapy) with the potential need for additional therapies. All cases of gestational trophoblastic neoplasia should be discussed at a multidisciplinary cancer case conference and registered in a centralized (regional and/or national) database. EVIDENCE: Relevant studies from 2002 onwards were searched in Embase, MEDLINE, the Cochrane Central Register of Controlled Trials, and Cochrane Systematic Reviews using the following terms, either alone or in combination: trophoblastic neoplasms, choriocarcinoma, trophoblastic tumor, placental site, gestational trophoblastic disease, hydatidiform mole, drug therapy, surgical therapy, radiotherapy, cure, complications, recurrence, survival, prognosis, pregnancy outcome, disease outcome, treatment outcome, and remission. The initial search was performed in April 2017 and updated in May 2019. 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. Additional significant articles were identified through cross-referencing the identified reviews. The total number of studies identified was 673, with 79 studies cited in this review. VALIDATION METHODS: The content and recommendations were drafted and agreed upon by the authors. The Executive and Board of Directors of the Society of Gynecologic Oncology of Canada reviewed the content and submitted comments for consideration, and the Board of Directors for the Society of Obstetricians and Gynaecologists of Canada 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 (GRADE) methodology framework. See the online appendix tables for key to grading and interpretation of recommendations. BENEFITS: These guidelines will assist physicians in promptly diagnosing gestational trophoblastic diseases and urgently referring patients diagnosed with gestational trophoblastic neoplasia to gynaecologic oncology for specialized management. Treating gestational trophoblastic neoplasia in specialized centres with the use of centralized databases allows for capturing and comparing data on treatment outcomes of patients with these rare tumours and for optimizing patient care.

Response to Multi-Line Chemotherapy in Non-Serous Epithelial Ovarian Cancer.

OBJECTIVES: To describe the response rate to chemotherapy, rates of recurrence, and overall survival in patients with non-serous epithelial ovarian cancers. METHODS: This retrospective cohort study used the Manitoba Cancer Registry to identify all women with non-serous epithelial ovarian, fallopian, or peritoneal cancer treated between 1995 and 2010. Chart review entailed extracting information regarding therapy and outcomes. All patients with recurrence were identified and response to chemotherapy was assessed. RESULTS: We identified 392 patients with non-serous ovarian cancers, 192 of whom received chemotherapy in the first-line setting. Optimal debulking resulted in improvements in rates of recurrence and overall survival (P < 0.001). Histology did not have an effect on recurrence or overall survival. Forty-eight patients (25%) had a recurrence and received second-line therapy, and 21 (11%) received third-line therapy. Response rates were similar regardless of histology. In the second-line setting, 40.9%-83.3% of patients (other > mucinous > clear cell > endometrioid) and in the third-line setting, 33.3%-75.0% of patients (other > mucinous > clear cell > endometrioid) received >6 lines of chemotherapy. Twenty-three percent of patients experienced a recurrence within 2 years of first-line therapy. Two-year survival was 79.4% after first-line treatment, 27.6% after second-line treatment, and 19.5% after third-line treatment. CONCLUSION: Patients with clear cell ovarian cancer had chemotherapy continuation rates similar to those of previously reported studies. This is one of the first studies reporting response rates for mucinous and endometrioid subtypes. Recurrent disease responds to treatment with second- and third-line therapy, emphasizing the importance of offering patients subsequent lines of chemotherapy for disease management. Further studies are needed to determine the optimal regimen.

Guideline No. 403: Initial Investigation and Management of Adnexal Masses.

OBJECTIVES: To aid primary care physicians, emergency medicine physicians, and gynaecologists in the initial investigation of adnexal masses, defined as lumps that appear near the uterus or in or around ovaries, fallopian tubes, or surrounding connective tissue, and to outline recommendations for identifying women who would benefit from a referral to a gynaecologic oncologist for further management. INTENDED USERS: Gynaecologists, obstetricians, family physicians, general surgeons, emergency medicine specialists, radiologists, sonographers, nurses, medical learners, residents, and fellows. TARGET POPULATION: Adult women 18 years of age and older presenting for the evaluation of an adnexal mass. OPTIONS: Women with adnexal masses should be assessed for personal risk factors, history, and physical findings. Initial evaluation should also include imaging and laboratory testing to triage women for management of their care either by a gynaecologic oncologist or as per SOGC guideline no. 404 on the initial investigation and management of benign ovarian masses. EVIDENCE: A search of PubMed, Cochrane Wiley, and the Cochrane systematic reviews was conducted in January 2018 for English-language materials involving human subjects published since 2000 using three sets of terms: (i) ovarian cancer, ovarian carcinoma, adnexal disease, ovarian neoplasm, adnexal mass, fallopian tube disease, fallopian tube neoplasm, ovarian cyst, and ovarian tumour; (ii) the above terms in combination with predict neoplasm staging, follow-up, and staging; and (iii) the above two sets of terms in combination with ultrasound, tumour marker, CA 125, CEA, CA19-9, HE4, multivariable-index-assay, risk-of-ovarian-malignancy-algorithm, risk-of-malignancy-index, diagnostic imaging, CT, MRI, and PET. Relevant evidence was selected for inclusion in descending order of quality of evidence as follows: meta-analyses, systematic reviews, guidelines, randomized controlled trials, prospective cohort studies, observational studies, non-systematic reviews, case series, and reports. Additional articles were identified through cross-referencing the identified reviews. The total number of studies identified was 2350, with 59 being included in this review. VALIDATION METHODS: The content and recommendations were drafted and agreed upon by the authors. The Executive and Board of the Society of Gynecologic Oncology of Canada reviewed the content and submitted comments for consideration. The Board of Directors of the Society of Obstetricians and Gynaecologists of Canada 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 (GRADE) methodology framework (Table A1 of Online Appendix A). See Table A2 of Online Appendix A for the interpretation of strong and weak recommendations. The summary of findings is available upon request. BENEFITS, HARMS, COSTS: Adnexal masses are common, and guidelines on how to triage them and manage the care of patients presenting with adnexal masses will continue to guide the practice of primary care providers and gynaecologists. Ovarian cancer outcomes are improved when initial surgery is performed by a gynaecologic oncologist, likely as a result of complete surgical staging and optimal cytoreduction. Given these superior outcomes, guidelines to assist in the triage of adnexal masses and the referral and management of the care of patients with an adnexal mass are critical. SUMMARY STATEMENTS (GRADE RATINGS IN PARENTHESES): RECOMMENDATIONS (GRADE RATINGS IN PARENTHESES).

No. 370-Management of Squamous Cell Cancer of the Vulva.

OBJECTIVE: This guideline reviews the clinical evaluation and management of squamous cell cancer (SCC) of the vulva with respect to diagnosis, primary surgical, radiation, or chemotherapy management and need for adjuvant treatment with chemotherapy and/or radiation therapy. Other vulvar cancer pathologic diagnoses are not included in the guideline. INTENDED USERS: The first part of this document which includes recommendations 1 through 3 is for general gynaecologists, obstetricians, family doctors, registered nurses, nurse practitioners, residents, and health care providers with a focus on the presentation, diagnosis, and updated information about surgical procedures performed by subspecialists. The surgical management and treatment of advanced vulvar cancer are intended for gynaecologic oncologists, radiation oncologists, and medical oncologists who treat these complex patients. This guideline is intended to provide information for interested parties who may follow these patients once treatment is complete. TARGET POPULATION: Adult women (18 years and older) with SCC of the vulva. Excluded from these guidelines are women with preinvasive disease. OPTIONS: Women diagnosed with SCC of the vulva should be referred to a gynaecologic oncologist for initial evaluation, consideration for primary surgery and inguinal lymph node assessment, and potentially adjuvant radiation and/or chemotherapy. All cases of vulvar cancer should have access to discussion at a multidisciplinary cancer case conference. Women who would otherwise require radical surgery such as abdominal-perineal resection or exenterative procedures may be considered for primary treatment with radiation and/or chemotherapy. EVIDENCE: For this guideline, 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: vulva, vulvar cancer, inguinofemoral lymph node dissection, sentinel nodes, systemic chemotherapy, radiotherapy, neoadjuvant, adjuvant, primary, exenteration, survival, follow up. The initial search was performed in September 2016 with a final literature search in May 2017. 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. Additional significant articles were identified through cross-referencing the identified reviews. The total number of studies identified was 286, and 78 studies were included in this review. VALIDATION METHODS: The content and recommendations were drafted and agreed upon 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 Society of Obstetricians and Gynaecologists of Canada 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 (GRADE) methodology framework (Table 1). The interpretation of strong and weak recommendations is described in Table 2. The Summary of Findings is available upon request.

The committee also promotes the centralization of treatment of vulvar cancer in specialized treatment centres. 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 the Society of Obstetricians and Gynaecologists of Canada. SUMMARY STATEMENTS: RECOMMENDATIONS.

Low-Risk Gestational Trophoblastic Neoplasia in Manitoba: Experience With Alternating Methotrexate and Dactinomycin.

OBJECTIVES: The aim of this study was to review the treatment and outcomes of low-risk gestational trophoblastic neoplasia (GTN) in Manitoba over more than 3 decades, with a focus on those treated with alternating methotrexate and dactinomycin, a protocol that has only rarely been described. MATERIALS AND METHODS: We retrospectively reviewed all patients with GTN referred to CancerCare Manitoba from January 1977 to December 2012. Cases were classified as low risk as per the modified WHO-FIGO prognostic scoring system (score, ≤6). Demographic, treatment, and outcomes data were abstracted, and descriptive statistics and time-to-event analysis were performed. The low-risk protocol used at CancerCare Manitoba consists of alternating single-agent use of methotrexate and dactinomycin, each for 5 days, on a 14-day cycle. RESULTS: Sixty-seven cases of GTN were identified, of which 52 were low risk. Thirty-nine patients were initiated on alternating methotrexate and dactinomycin. Thirty-four (87.2%) achieved primary cure on this regimen, with a median of 4.4 cycles administered (range, 2-7). Median time to response was 56 days. One patient achieved cure after receiving a repeat course of methotrexate as their final cycle. Second-line multiagent chemotherapy was required by 4 patients. Two patients experienced grade 3 toxicities, and none greater than grade 3. There were no recurrences. CONCLUSIONS: Alternating methotrexate and dactinomycin is an effective treatment protocol for low-risk GTN, with high rates of primary cure and acceptable toxicity.

Rate of Appendiceal Metastasis with Non-Serous Epithelial Ovarian Cancer in Manitoba.

OBJECTIVE: This study sought to evaluate the rate of appendiceal involvement in non-serous mucinous and endometrioid-associated epithelial ovarian cancers. METHODS: The Manitoba Cancer Registry and CancerCare database were used to find all women with non-serous epithelial ovarian, fallopian tube, or primary peritoneal cancer between 1995 and 2011. All patients with an appendectomy were then identified, and their final pathology findings were reviewed. Women who did not receive treatment or lacked follow-up were excluded. RESULTS: We identified 338 patients from 1995-2011 with no prior appendectomy. Of these, 16.6% received an appendectomy, and 22.8% were clinically evaluated. Most cases within this cohort were mucinous (62%) and stage 1 (63%). Four appendiceal metastases were identified (7.2%), and one half appeared clinically normal at the time of surgery (3.6%). Within the mucinous histologic type, 32.7% of patients received an appendectomy, with a metastatic rate of 5.7%. Of the 127 endometrioid cases, only 10 patients received an appendectomy, and 2 were found to have metastases. No metastases were found in the 85 patients in the clear cell cohort, only 5 of whom received an appendectomy. CONCLUSION: Routine appendectomy or clinical assessment of the appendix is valuable for all non-serous ovarian cancers. The rate of involvement for endometriosis-associated ovarian cancers may be significantly higher than expected, and further studies need to be conducted.

Examining the Selection Criteria of Neoadjuvant Chemotherapy Patients.

OBJECTIVES: To identify predictors of neoadjuvant chemotherapy (NAC) and to examine toxicities, dose reduction, interruptions, and second-line chemotherapy MATERIALS AND METHODS: A retrospective chart review of 391 patients with late-stage ovarian cancer diagnosed between January 1, 2004 and December 31, 2010 was conducted. Logistic regression was used to predict chemotherapy type. Cumulative incidence of toxicities, dose reduction, and treatment interruption were calculated using the Kaplan-Meier method. Overall survival was analyzed using time-varying Cox regression models. A competing risk model was used to predict second-line chemotherapy with death as a competing risk. RESULTS: Older patients were less likely to receive primary debulking (OR 0.710; 95% CI 0.55-0.92, P = 0.0108), as were patients with longer diagnostic intervals. Clear-cell, endometrioid, and mucinous carcinoma were more likely to receive adjuvant treatment than unclassified epithelial (OR 6.964; 95% CI 2.02-24.03, P = 0.0021). Adjuvant patients experienced higher incidence of chemotherapy toxicities (P <0.0001) and treatment interruption (P = 0.016) at 3 months. There was no statistically significant difference in the incidence of chemotherapy dose reduction of >20% in the NAC and adjuvant populations (P = 0.142). Neoadjuvant patients were more likely to require more than one line of chemotherapy ([Subhazard Ratio] = 4.334; 95% CI 2.51-7.50, P <0.0001). CONCLUSION: Our study found that patients with shorter diagnostic intervals, more advanced age, and unclassified epithelial histotype were more likely to receive NAC. NAC patients did not experience a higher incidence of chemotherapy toxicities, treatment interruption, or dose reduction. There is treatment selection bias for sicker patients being treated with NAC.

Examining the Effects of Time to Diagnosis, Income, Symptoms, and Incidental Detection on Overall Survival in Epithelial Ovarian Cancer: Manitoba Ovarian Cancer Outcomes (MOCO) Study Group.

OBJECTIVE: The primary objectives of this study were to analyze data on time to diagnosis and correlate this with overall survival. We secondarily analyzed the effects of emergency room visits, symptoms, incidental findings, residence, socioeconomic status, and residual disease on overall survival. METHODS: This retrospective population-based descriptive cohort study examined all invasive ovarian cancer cases in Manitoba, Canada, between 2004 and 2010. Clinicopathologic, socioeconomic, and outcome data were collected. Analysis was performed with Cox and logistic regression stratified by early and late stage. RESULTS: Six hundred eighty-seven ovarian cancer patients were identified, with a final cohort of 601 patients: 210 with early-stage (1/2) and 391 with late-stage (3/4) disease. No presenting symptoms were associated with survival outcome. Poorer survival was associated with increasing age (P = 0.0016) and neoadjuvant chemotherapy (P = 0.0037). Higher income within the urban setting was also associated with a survival advantage (P = 0.0037), whereas initial presentation to the emergency room (P = 0.0399) was associated with decreased survival. Finally, for advanced-stage disease, incidental diagnosis had a significantly improved overall survival (hazard ratio, 0.424; 95% confidence interval, 0.27-0.67; P = 0.0003), even when accounting for confounding factors. Time from first presentation to diagnosis was associated with survival (P = 0.0309). CONCLUSIONS: This study found that time to diagnosis did not negatively impact overall survival, although there was an association. Age, morphology, treatment type, residual disease, medical comorbidities, and income were significant prognostic factors. This is the first study to show a survival advantage to incidentally finding an ovarian cancer. Further research is needed on the outcomes of pelvic examination.
