ABSTRACT
BACKGROUND: Standard treatment for locally advanced cervical cancer is chemoradiotherapy, but many patients relapse and die of metastatic disease. We aimed to determine the effects on survival of adjuvant chemotherapy after chemoradiotherapy. METHODS: The OUTBACK trial was a multicentre, open-label, randomised, phase 3 trial done in 157 hospitals in Australia, China, Canada, New Zealand, Saudi Arabia, Singapore, and the USA. Eligible participants were aged 18 year or older with histologically confirmed squamous cell carcinoma, adenosquamous cell carcinoma, or adenocarcinoma of the cervix (FIGO 2008 stage IB1 disease with nodal involvement, or stage IB2, II, IIIB, or IVA disease), Eastern Cooperative Oncology Group performance status 0-2, and adequate bone marrow and organ function. Participants were randomly assigned centrally (1:1) using a minimisation approach and stratified by pelvic or common iliac nodal involvement, requirement for extended-field radiotherapy, FIGO 2008 stage, age, and site to receive standard cisplatin-based chemoradiotherapy (40 mg/m2 cisplatin intravenously once-a-week for 5 weeks, during radiotherapy with 45·0-50·4 Gy external beam radiotherapy delivered in fractions of 1·8 Gy to the whole pelvis plus brachytherapy; chemoradiotherapy only group) or standard cisplatin-based chemoradiotherapy followed by adjuvant chemotherapy with four cycles of carboplatin (area under the receiver operator curve 5) and paclitaxel (155 mg/m2) given intravenously on day 1 of a 21 day cycle (adjuvant chemotherapy group). The primary endpoint was overall survival at 5 years, analysed in the intention-to-treat population (ie, all eligible patients who were randomly assigned). Safety was assessed in all patients in the chemoradiotherapy only group who started chemoradiotherapy and all patients in the adjuvant chemotherapy group who received at least one dose of adjuvant chemotherapy. The OUTBACK trial is registered with ClinicalTrials.gov, NCT01414608, and the Australia New Zealand Clinical Trial Registry, ACTRN12610000732088. FINDINGS: Between April 15, 2011, and June 26, 2017, 926 patients were enrolled and randomly assigned to the chemoradiotherapy only group (n=461) or the adjuvant chemotherapy group (n=465), of whom 919 were eligible (456 in the chemoradiotherapy only group and 463 in the adjuvant chemotherapy group; median age 46 years [IQR 37 to 55]; 663 [72%] were White, 121 [13%] were Black or African American, 53 [6%] were Asian, 24 [3%] were Aboriginal or Pacific islander, and 57 [6%] were other races) and included in the analysis. As of data cutoff (April 12, 2021), median follow-up was 60 months (IQR 45 to 65). 5-year overall survival was 72% (95% CI 67 to 76) in the adjuvant chemotherapy group (105 deaths) and 71% (66 to 75) in the chemoradiotherapy only group (116 deaths; difference 1% [95% CI -6 to 7]; hazard ratio 0·90 [95% CI 0·70 to 1·17]; p=0·81). In the safety population, the most common clinically significant grade 3-4 adverse events were decreased neutrophils (71 [20%] in the adjuvant chemotherapy group vs 34 [8%] in the chemoradiotherapy only group), and anaemia (66 [18%] vs 34 [8%]). Serious adverse events occurred in 107 (30%) in the adjuvant chemotherapy group versus 98 (22%) in the chemoradiotherapy only group, most commonly due to infectious complications. There were no treatment-related deaths. INTERPRETATION: Adjuvant carboplatin and paclitaxel chemotherapy given after standard cisplatin-based chemoradiotherapy for unselected locally advanced cervical cancer increased short-term toxicity and did not improve overall survival; therefore, it should not be given in this setting.

OBJECTIVE: Detection of lymph node metastases in cervical cancer patients is important for guiding treatment decisions, however accuracies of current detection methods are limited. We evaluated associations of abnormal glycosylation, represented by Tn and STn antigens on mucin (MUC) proteins, in primary tumor specimens with lymph node metastasis or recurrence of cervical cancer patients. METHODS: Surgical specimens were prospectively collected from 139 patients with locally-advanced cervical cancer undergoing lymphadenectomy enrolled in a nation-wide clinical trial (NCT00460356). Of these patients, 133 had primary cervix tumor, 67 had pelvic lymph node (PLN) and 28 had para-aortic lymph node (PALN) specimens. Fixed tissue serial sections were immunohistochemically stained for Tn, STn, MUC1 or MUC4. Neuraminidase was used to validate Tn versus STn antibody specificity. Stain scores were compared with clinical characteristics. RESULTS: Primary tumor STn expression above the median was associated with negative PLN status (p-value: 0.0387; odds ratio 0.439, 95% CI: 0.206 to 0.935). PLN had higher STn compared to primary tumor, while primary tumor had higher MUC1 compared to PALN, and MUC4 compared to PALN or PLN (p = 0.017, p = 0.011, p = 0.016 and p < 0.001, respectively). Tn and STn expression correlated in primary tumor, PALN, and PLN, Tn and MUC1 expression correlated in primary tumors only (Spearman correlation coefficient [r] = 0.301, r = 0.686, r = 0.603 and r = 0.249, respectively). CONCLUSIONS: STn antigen expression in primary cervical tumors is a candidate biomarker for guiding treatment decisions and for mechanistic involvement in PLN metastases.

OBJECTIVE: To evaluate how women with epithelial ovarian cancer (EOC), dichotomized by BRCA status, tolerate intravenous (IV) or intraperitoneal (IP) chemotherapy given with veliparib and bevacizumab (bev) on a GOG phase I study (GOG 9923, NCT00989651). METHODS: This is an unplanned, post hoc analysis of an IRB approved, multi-institutional, prospective study (GOG 9923). Clinical characteristics and toxicity data based on BRCA status were evaluated and descriptive statistics were used to summarize baseline patient characteristics and toxicities. The Kaplan Meier method was used to generate survival estimates. RESULTS: Four hundred twenty-four patients were evaluable. Patients were treated with IV carboplatin, paclitaxel, and bev every 21 days (regimen 1), weekly IV paclitaxel with carboplatin and bev (regimen 2) or IV paclitaxel and bev with IP cisplatin (regimen 3). Bev was continued as maintenance in all arms. Within each of these regimens, veliparib was given either twice daily for the entirety of each cycle (continuous) or on days -2 to 5 (intermittent). Ten percent of patients treated on regimen 1, 12% on regimen 2, and 19.8% on regimen 3 had BRCA-associated tumors. Patients with BRCA-associated tumors, when compared to wild type, experienced similar rates of anemia, febrile neutropenia (, abdominal pain, colonic perforation, nausea, vomiting, and peripheral sensory neuropathy. Median progression free survival (PFS) was not significantly different between BRCA-associated and wild type cancers (HR 0.96, CI 0.65-1.42), though this study's primary aim was not to evaluate outcomes. CONCLUSIONS: Germline BRCA mutations positively affect chemosensitivity in EOC, but whether differences in toxicities among BRCA-associated and BRCA wild type tumors existed was previously not reported. In this population with newly diagnosed ovarian cancer no differences in reported toxicity between the two groups was observed.

BACKGROUND: Improvements in disease free survival for epithelial ovarian, peritoneal or fallopian tube cancer (EOC) will only come with improved primary therapy. Incorporation of poly-ADP-ribose inhibitors (PARPi) in the frontline setting may represent one strategy. This study sought to determine the maximum tolerated and feasible doses of the PARPi veliparib in combination with chemotherapy for EOC. METHODS: A phase I, 3 + 3 dose escalation evaluated dose-limiting toxicities (DLTs) in cycles 1-2. Once <2/6 patients experienced a DLT, that dose level expanded to evaluate feasibility over 4 cycles. This study opened 10/2009 and closed 8/2016. Eligible patients had untreated, stage II-IV EOC. Veliparib was added either continuous (day 1-21) or intermittent (day - 2 to 5) during 6 cycles of chemotherapy. Three chemotherapy backbones were evaluated (2 intravenous (q3week and weekly) and 1 intraperitoneal (IP)) all inclusive of bevacizumab with and as maintenance to 22 cycles. FINDINGS: Dose evaluations for 424 treated patients were available. Regimen 1 (q3 week), continuous (Reg1c) the maximum tolerated dose (MTD) was 250 mg veliparib BID and feasible dose was 150 mg BID. For regimen 1, intermittent (Reg1i) the MTD and feasible dose were 400 and 250 mg BID. For Reg2c (weekly paclitaxel) the MTD and feasible dose were 150 mg BID. For Reg2i the MTD and feasible dose were 250 and 150 mg BID. For Reg3c (IP) the MTD and feasible dose were 150 mg BID and for Reg3i (IP), the MTD and feasible dose were 400 mg and 300 mg BID. INTERPRETATION: The feasible dose for Reg1c, 2c, 2i and 3c was 150 mg po BID. For Reg1i and 3i the dose was pushed to 250 and 300 mg po BID respectively. There is no apparent difference in efficacy between continuous and intermittent dosing indicating that the higher doses achieved in intermittent dosing may not be needed. (NCT00989651).

OBJECTIVE: We sought to determine safety and efficacy of the AKT inhibitor, GSK2141795, combined with the MEK inhibitor, trametinib, in endometrial cancer. METHODS: Patients with measurable recurrent endometrial cancer were eligible. One to two prior cytotoxic regimens were allowed; prior use of a MEK or PI3K pathway inhibitor was excluded. Initial trial design consisted of a KRAS mutation stratified randomized phase II with a safety lead-in evaluating the combination. For the safety lead in, the previously recommended phase 2 dose (RP2D; trametinib 1.5 mg, GSK2141795 50 mg) was chosen for Dose Level 1 (DL1). RESULTS: Of 26 enrolled patients, 14 were treated on DL1 and 12 were treated on DL-1 (trametinib 1.5 mg, GSK2141795 25 mg). Most common histologies were endometrioid (58%) and serous (27%). Four of 25 (16%) patients were KRAS mutant. Dose limiting toxicities (DLTs) were assessed during cycle 1. DL1 had 8 DLTs (hypertension (n = 2), mucositis (2), rash (2), dehydration, stroke/acute kidney injury). DL1 was deemed non-tolerable so DL-1 was explored. DL-1 had no DLTs. Sixty-five percent of patients had ≥ grade 3 toxicity. There were no responses in DL1 (0%, 90%CI 0-15%) and 1 response in DL-1 (8.3%, 90%CI 0.4-33.9%). Proportion PFS at 6 months for DL1 is 14%, and 25% for DL-1. CONCLUSION: The combination of trametinib and GSK2141795 had high levels of toxicity in endometrial cancer at the previously RP2D but was tolerable at a reduced dose. Due to insufficient preliminary efficacy at a tolerable dose, the Phase II study was not initiated.

Ovary is one of the extrapancreatic sites of origin of solid pseudopapillary neoplasm (SPN). Only 9 cases of primary ovarian SPN, 1 with CTNNB1 mutation similar to pancreatic SPN, have been reported in the English literature. We describe the second case of ovarian SPN with confirmed CTNNB1 mutation. A 49-year-old postmenopausal woman presented with a 4.5 cm right ovarian mass. Ovarian mass showed histologic and immunohistochemical features of pancreatic SPN. The ovarian surface was intact and uninvolved. Ki-67 index was low (1%-5%). DNA sequencing of CTNNB1 exon 3 revealed c.98C>G (p.S33C), a well-characterized activating mutation. Our case adds to the growing body of evidence that primary ovarian SPN are phenotypically and genotypically similar to pancreatic SPN.

BACKGROUND: Synuclein-γ (SNCG) is highly expressed in advanced solid tumors, including uterine serous carcinoma (USC). The objective of the current study was to determine whether SNCG protein was associated with survival and clinical covariates using the largest existing collection of USCs from the Gynecologic Oncology Group (GOG-8023). METHODS: High-density tissue microarrays (TMAs) of tumor tissues from 313 patients with USC were stained by immunohistochemistry for SNCG, p53, p16, FOLR1, pERK, pAKT, ER, PR, and HER2/neu. Associations of SNCG and other tumor markers with overall and progression-free survival were assessed using log-rank tests and Cox proportional-hazards models, which also were adjusted for age, race, and stage. RESULTS: The overall survival at 5 years was 46% for women with high SNCG expression and 62% for those with low SNCG expression (log-rank P = .021; hazard ratio [HR], 1.31; 95% confidence interval [CI], 0.91-1.9 in adjusted Cox model). The progression-free survival rate at 5 years was worse for women who had high SNCG expression, at 40%, compared with 56% for those who had low SNCG expression (log-rank P = .0081; HR, 1.36; 95% CI, 0.96-1.92 in adjusted Cox model). High levels of both p53 and p16 were significantly associated with worse overall survival (p53: HR, 4.20 [95% CI, 1.54-11.45]; p16: HR, 1.95 [95% CI, 1.01-3.75]) and progression-free survival (p53: HR, 2.16 [95% CI, 1.09-4.27]; p16: HR, 1.53 [95% CI, 0.87-2.69]) compared with low levels. CONCLUSIONS: This largest collection of USCs to date demonstrates that SNCG was associated with poor survival in univariate analyses. SNCG does not predict survival outcome independent of p53 and p16 in models that jointly consider multiple markers. Cancer 2017;123:1144-1155. © 2016 American Cancer Society.

OBJECTIVE: This two-stage Phase II study assessed the activity of single agent alisertib in patients with recurrent/persistent uterine leiomyosarcoma (uLMS). METHODS: Eligibility criteria included histologically-confirmed, recurrent or persistent uLMS, age≥18, 1-2 prior cytotoxic regimens, and RECIST version 1.1 measurable disease. The primary objective of the study was to evaluate the efficacy of alisertib through the frequency of patients with objective tumor responses and the frequency who survived event-free for at least 6months (EFS6). The endpoints for EFS were RECIST progression, death, or beginning a subsequent therapy. The null hypothesis jointly specified the probability of a patient experiencing a tumor response to less than or equal to 5% and the probability of a patient surviving event-free for at least 6months to less than or equal to 20%. A two-stage design was used with a target accrual of 23 patients for stage 1 and 47 pts. cumulative for stage 2. Confidence intervals do not correct for multiplicity. RESULTS: Twenty-three patients were enrolled with two patients excluded on central histology review, yielding 21 eligible patients. Median age was 61years. Prior treatment was either 1 cytotoxic regimen (71.4%) or 2 (28.6%). The most common treatment related AEs (grade 3 or worse) were anemia Hensley et al. (2008a) , leukopenia Hensley et al. (2008b) , neutropenia Maki et al. (2007) , thrombocytopenia Huang et al. (2012) , mucositis Hensley et al. (2008a) , diarrhea Huang et al. (2012) , and palmer-planter syndrome Zivanovic et al. (2012) . There were no objective responses (0%; 90% CI: 0-10.4%). Best response was stable disease (38.1%); 12 patients had progressive disease (57.1%). EFS6 was 0% (90% CI: 0-10.4%). Median PFS and OS were 1.7 (90% CI: 1.4-3.2) and 14.5months (90% CI: 7.6 - NA), respectively. CONCLUSION: Alisertib did not demonstrate clinically meaningful single agent activity in previously treated uLMS.

The American Society for Colposcopy and Cervical Pathology (ASCCP) Colposcopy Standards recommendations address the role of colposcopy and directed biopsy for cervical cancer prevention in the United States (US). The recommendations were developed by an expert working group appointed by ASCCP's Board of Directors. An extensive literature review was conducted and supplemented by a systematic review and meta-analysis of unpublished data. In addition, a survey of practicing colposcopists was conducted to assess current colposcopy practice in the US. Recommendations were approved by the working group members, and the final revisions were made based on comments received from the public. The recommendations cover terminology, risk-based colposcopy, colposcopy procedures, and colposcopy adjuncts. The ASCCP Colposcopy Standards recommendations are an important step toward raising the standard of colposcopy services delivered to women in the US. Because cervical cancer screening programs are currently undergoing important changes that may affect colposcopy performance, updates to some of the current recommendations may be necessary in the future.

Mesonephric-like adenocarcinoma (MLA) of the endometrium shows a variety of morphologic appearances, including small glands, tubules with eosinophilic materials in the lumen, prominent papillary patterns, spindled cells, solid formations, and corded and hyalinized patterns. Unique morphology, characteristic immunohistochemical staining patterns, molecular alterations, and awareness of the pathologists make it possible to identify this tumor accurately. This report of two additional morphologic patterns, intestinal goblet cells mimicking intestinal-type mucinous carcinoma and squamous differentiation with spindle and epithelioid cells mimicking carcinosarcoma of the endometrium will expand the literature on MLA.
ABSTRACT
PURPOSE: The interleukin-6/Janus kinase (JAK)/signal transducers and activators of transcription 3 axis is a reported driver of chemotherapy resistance. We hypothesized that adding the JAK1/2 inhibitor ruxolitinib to standard chemotherapy would be tolerable and improve progression-free survival (PFS) in patients with ovarian cancer in the upfront setting. MATERIALS AND METHODS: Patients with ovarian/fallopian tube/primary peritoneal carcinoma recommended for neoadjuvant chemotherapy were eligible. In phase I, treatment was initiated with dose-dense paclitaxel (P) 70 mg/m2 once daily on days 1, 8, and 15; carboplatin AUC 5 intravenously day 1; and ruxolitinib 15 mg orally (PO) twice a day, every 21 days (dose level 1). Interval debulking surgery (IDS) was required after cycle 3. Patients then received three additional cycles of chemotherapy/ruxolitinib, followed by maintenance ruxolitinib. In the randomized phase II, patients were randomly assigned to paclitaxel/carboplatin with or without ruxolitinib at 15 mg PO twice a day for three cycles, IDS, followed by another three cycles of chemotherapy/ruxolitinib, without further maintenance ruxolitinib. The primary phase II end point was PFS. RESULTS: Seventeen patients were enrolled in phase I. The maximum tolerated dose and recommended phase II dose were established to be dose level 1. One hundred thirty patients were enrolled in phase II with a median follow-up of 24 months. The regimen was well tolerated, with a trend toward higher grade 3 to 4 anemia (64% v 27%), grade 3 to 4 neutropenia (53% v 37%), and thromboembolic events (12.6% v 2.4%) in the experimental arm. In the randomized phase II, the median PFS in the reference arm was 11.6 versus 14.6 in the experimental, hazard ratio (HR) for PFS was 0.702 (log-rank P = .059). The overall survival HR was 0.785 (P = .24). CONCLUSION: Ruxolitinib 15 mg PO twice a day was well tolerated with acceptable toxicity in combination with paclitaxel/carboplatin chemotherapy. The primary end point of prolongation of PFS was achieved in the experimental arm, warranting further investigation.

OBJECTIVES: To determine prognostic factors for survival in ovarian cancer patients treated with intraperitoneal (IP) chemotherapy using ancillary data from cooperative group clinical trials. METHODS: Data were collected from 428 patients with stage III ovarian cancer who underwent optimal surgical cytoreduction (<1 cm) followed by IP paclitaxel/platinum chemotherapy. Primary endpoints were progression free survival (PFS) and overall survival (OS). Potential prognostic variables were included in Cox proportional hazard regression models. Multivariate analysis was conducted to identify independent prognostic factors. RESULTS: Median PFS was 24.9 months (95% CI, 23.0-29.2) and median OS was 61.8 months (95% CI, 55.5-69.8). Predictors for PFS were histology, surgical stage and residual disease. Age, histology, and residual disease were prognostic for OS. There were no differences in the hazard ratio for death or progression between patients with positive, negative, or unknown lymph node status. For patients receiving IP chemotherapy (n=428), 36% of patients had no residual disease with median PFS of 43.2 months (95% CI 32.5-60.4) and median OS of 110 months (95% CI, 60.0-161.3). CONCLUSIONS: Age, histology, and extent of residual disease were predictors of OS in stage III patients treated with IP chemotherapy following optimal cytoreduction. Patients with no residual disease following primary surgery that are treated with adjuvant platinum based IP chemotherapy have survival measures that exceed any rates previously seen in this population.

OBJECTIVE: Complete bilateral salpingectomy (CBS) can decrease the risk of developing ovarian cancer, although adoption of CBS at cesarean delivery (CD) for permanent contraception has been low. The primary objective was to measure the annual rates of CBS at CD before and after an educational initiative. The secondary objective was to assess rates of providers who offer CBS at CD and their comfort level with the procedure. METHODS: We performed an observational study of OBGYN physicians who perform CD at a single institution. We compared the annual rates of CBS among CD with permanent contraception procedures from the year before and the year after an in-person OBGYN Grand Rounds presentation on December 5, 2019 reviewing the latest research on opportunistic CBS at the time of CD. To evaluate the secondary objectives, anonymous surveys were administered to physicians in-person the month before the presentation. The statistical analysis included chi-square, Fisher's exact test, T-test, ANOVA, and the Cochran-Armitage trend test. RESULTS: After our educational intervention, annual rates of CBS at CD increased from 5.1% [12/05/2018-12/04/2019] to 31.8% [12/5/2019-12/4/2020] (p<0.001), and up to 52% in the last study quarter (p<0.001). Surgical outcomes were similar between tubal ligation and CBS, except for a 5-minute increased total operative time for CBS (p=0.005). Fifty physicians completed the survey prior to the presentation (93% response rate). All physicians offered CBS at time of hysterectomy and interval sterilization, while only 36% offered CBS at time of CD. More physicians felt comfortable performing a CBS with bipolar electrocautery (90%) than suture ligation (56%). CONCLUSION: Our presentation-based educational initiative was associated with a significant increase in performance of CBS at the time of CD.

PURPOSE: Tissue factor is highly expressed in cervical carcinoma and can be targeted by tisotumab vedotin (TV), an antibody-drug conjugate. This phase Ib/II study evaluated TV in combination with bevacizumab, pembrolizumab, or carboplatin for recurrent or metastatic cervical cancer (r/mCC). METHODS: This open-label, multicenter study (ClinicalTrials.gov identifier: NCT03786081) included dose-escalation arms that assessed dose-limiting toxicities (DLTs) and identified the recommended phase II dose (RP2D) of TV in combination with bevacizumab (arm A), pembrolizumab (arm B), or carboplatin (arm C). The dose-expansion arms evaluated TV antitumor activity and safety at RP2D in combination with carboplatin as first-line (1L) treatment (arm D) or with pembrolizumab as 1L (arm E) or second-/third-line (2L/3L) treatment (arm F). The primary end point of dose expansion was objective response rate (ORR). RESULTS: A total of 142 patients were enrolled. In dose escalation (n = 41), no DLTs were observed; the RP2D was TV 2 mg/kg plus bevacizumab 15 mg/kg on day 1 once every 3 weeks, pembrolizumab 200 mg on day 1 once every 3 weeks, or carboplatin AUC 5 on day 1 once every 3 weeks. In dose expansion (n = 101), the ORR was 54.5% (n/N, 18/33; 95% CI, 36.4 to 71.9) with 1L TV + carboplatin (arm D), 40.6% (n/N, 13/32; 95% CI, 23.7 to 59.4) with 1L TV + pembrolizumab (arm E), and 35.3% (12/34; 19.7 to 53.5) with 2L/3L TV + pembrolizumab (arm F). The median duration of response was 8.6 months, not reached, and 14.1 months, in arms D, E, and F, respectively. Grade ≥3 adverse events (≥15%) were anemia, diarrhea, nausea, and thrombocytopenia in arm D and anemia in arm F (none ≥15%, arm E). CONCLUSION: TV in combination with bevacizumab, carboplatin, or pembrolizumab demonstrated manageable safety and encouraging antitumor activity in treatment-naive and previously treated r/mCC.

Women with high-grade cervical intraepithelial neoplasia (HGCIN) frequently present with multiple cervical lesions and multiple concomitant Human papillomavirus (HPV) genotype infections. To elucidate HPV genotype attribution in different regions on the cervix, we performed molecular mapping of cervical disease in women with HGCIN. Thirteen subjects referred to colposcopy for abnormal cervical cancer screening results were included. A cervical smear and biopsies from 4 different areas on the cervix were collected. HPV genotyping using Linear Array (for cytology) or SPF(10) LiPA(25) (for histology) were performed in 13 smears, 52 whole sections from biopsies and 138 tissue regions isolated with laser capture microdissection (LCM). Twelve subjects had a diagnosis of CIN3 and one subject had a diagnosis of CIN2 based on the worst histology found in 4 biopsies. Eight of the 13 smears (62%) showed multiple genotype infections. Four of 13 women (31%) had multiple HPV infections in their biopsies. After performing LCM-PCR, only one woman (8%) had two different carcinogenic HPV types in morphologically distinct, but colliding HGCIN lesions. HPV16 was identified as the causal type in all women with HPV16 in cytology. A large proportion of other HPV types found in cervical smears were not detected at the tissue level. Using tissue-based genotyping and LCM-PCR analysis, we were able to attribute an individual HPV type to each area of CIN lesions. We demonstrate that HPV16 is even more etiologically dominant than previously thought, based on various genotype attribution models.

OBJECTIVE: Infrequent Pap screening is an important risk factor for cervical cancer. We studied the association between contraceptive methods, screening frequency, and cancer. METHODS: Women (n=2004) enrolled in the cross-sectional Study to Understand Cervical Cancer Endpoints and Determinants (SUCCEED) underwent colposcopy to evaluate an abnormal Pap test. Questionnaire data were compared between those with cervical intraepithelial neoplasia (CIN) 3/adenocarcinoma in situ (AIS) and those with invasive cancer to identify factors associated with cancer. Logistic regression was used to calculate age-stratified measures of association between contraceptive method and Pap frequency as well as tubal ligation (TL) and cancer risk. RESULTS: In all age groups, women with TL were more likely to have had no Pap screening in the previous 5 years compared to women using other contraception: 26-35 years (OR 4.6, 95% CI 2.4-8.6; p<0.001), 36-45 years (OR 3.8, 95% CI 2.1-7.0; p<0.001), and 46-55 years (OR 2.2, 95% CI 1.0-4.9; p=0.050). Subjects with cancer (n=163) were more likely to have had a TL (41% vs. 21%, p<0.001) than those with CIN 3/AIS (n=370). Age-stratified analyses showed increased odds of tubal ligation in women with cancer versus those with CIN 3/AIS between 25 and 45 years, with a significant increase in women 26 to 35 years old (OR 3.3, 95% CI 1.4-8.1; p=0.009). Adjusting for Pap frequency changed the effect only slightly, suggesting that increased risk was not fully mediated by lack of screening. CONCLUSION: Contraceptive type is associated with Pap screening. Women with TLs obtain less frequent Pap testing and may be at an increased risk for cervical cancer.

ABSTRACT
PURPOSE: NRG Oncology conducted a phase II trial to assess the antitumor activity and tolerability of copanlisib, a selective inhibitor of PIK3CA, in persistent or recurrent endometrial carcinoma harboring hotspot PIK3CA mutations. PATIENTS AND METHODS: Eligible patients had endometrial cancer with endometrioid, serous or mixed histology, a somatic PIK3CA gene mutation, measurable disease, and GOG performance status ≤2. Treatment consisted of IV copanlisib (60â¯mg weekly, day 1, 8 and 15 of 28-day cycle) until disease progression or prohibitive toxicity. The primary endpoints of the study were objective tumor response as assessed by RECIST 1.1 and to determine the nature and degree of toxicity of copanlisib as assessed by CTCAE version 4. The study used a 2-stage group sequential design. RESULTS: Eleven patients were enrolled onto stage I of the treatment trial. Five patients had endometrioid, four serous and two had a tumor of mixed histology. The most common PIK3CA mutation was Q546X (nâ¯=â¯3) in exon 9. The most common grade 3 or 4 AE was hyperglycemia. No grade 5 adverse events were reported. No clinical responses were detected. Six patients had a best overall response of stable disease. Of 11 who initiated treatment, 10 progressed on treatment. One patient with stable disease on copanlisib withdrew from treatment secondary to relocation. The median progression-free survival (PFS) was 2.8â¯months; at 6â¯months 27% were alive, progression-free. The median overall survival (OS) was 15.2â¯months. Due to the lack of CR/PR continuation of accrual to the second stage of accrual was not warranted. CONCLUSION: Copanlisib is well tolerated but has limited activity as a single agent in this population.
ABSTRACT
PURPOSE: In SOLO1, maintenance olaparib (300 mg twice daily) significantly improved progression-free survival (PFS) for patients with newly diagnosed BRCA1- and/or BRCA2-mutated advanced ovarian cancer compared with placebo (hazard ratio [HR], 0.30; 95% CI, 0.23 to 0.41; median not reached v 13.8 months). We investigated PFS in SOLO1 for subgroups of patients based on preselected baseline factors. PATIENTS AND METHODS: Investigator-assessed PFS subgroup analyses of SOLO1 included clinical response after platinum-based chemotherapy (complete [CR] or partial response [PR]), surgery type (upfront or interval surgery), disease status after surgery (residual or no gross residual disease), and BRCA mutation status (BRCA1 or BRCA2). Additionally, we evaluated PFS in patients with stage III disease who underwent upfront surgery and had no gross residual disease. We also report objective response rate. RESULTS: The risk of disease progression or death was reduced with olaparib compared with placebo by 69% (HR, 0.31; 95% CI, 0.21 to 0.46) and 63% (HR, 0.37; 95% CI, 0.24 to 0.58) in patients undergoing upfront or interval surgery; 56% (HR, 0.44; 95% CI, 0.25 to 0.77) and 67% (HR, 0.33; 95% CI, 0.23 to 0.46) in patients with residual or no residual disease after surgery; 66% (HR, 0.34; 95% CI, 0.24 to 0.47) and 69% in women with clinical CR or PR at baseline (HR, 0.31; 95% CI, 0.18 to 0.52); and 59% (HR, 0.41; 95% CI, 0.30 to 0.56) and 80% (HR 0.20; 95% CI, 0.10 to 0.37) in patients with a BRCA1 or BRCA2 mutation, respectively. CONCLUSION: Patients with newly diagnosed advanced ovarian cancer achieve substantial benefit from maintenance olaparib treatment regardless of baseline surgery outcome, response to chemotherapy, or BRCA mutation type.

With the goal of identifying diagnostic and prognostic biomarkers in endometrial cancer, miRNA-profiling was carried out with formalin-fixed paraffin embedded (FFPE) tissue samples from 49 endometrial cancer patients. Results using an 84-cancer specific miRNA panel identified the upregulation of miR-141-3p and miR-96-5p along with a downregulation of miR-26, miR-126-3p, miR-23b, miR-195-5p, miR-374a and let-7 family of miRNAs in endometrial cancer. We validated the dysregulated expression of the identified miRNAs in a panel of endometrial cancer cell-lines. Immunohistochemical analysis of the tissue micro array derived from these patients established the functional correlation between the decreased expression of tumor suppressive miRNAs and their target oncogenes: ERBB2, EGFR, EPHA2, BAX, GNA12, GNA13, and JUN. Comparative analysis of the samples from the patients with extended progression-free survival (PFS) ( > 21 months) versus the patients with the PFS of < 21 months indicated increased expression of tumor suppressive miR-142-3p, miR-142-5p, and miR-15a-5p in samples from extended PFS patients. In addition to defining a specific set of miRNAs and their target genes as potential diagnostic biomarkers, our studies have identified tumor suppressive miR-142 cluster and miR-15a as predictors of favorable prognosis for therapy response in endometrial cancer.
