RESUMEN
BACKGROUND: Immunotherapy has transformed the endometrial cancer treatment landscape, particularly for those exhibiting mismatch repair deficiency [MMRd/microsatellite instability-hypermutated (MSI-H)]. A growing body of evidence supports the integration of immunotherapy with chemotherapy as a first-line treatment strategy. Recently, findings from ongoing trials such as RUBY (NCT03981796), NRG-GY018 (NCT03914612), AtTEnd (NCT03603184), and DUO-E (NCT04269200) have been disclosed. MATERIALS AND METHODS: This paper constitutes a review and meta-analysis of phase III trials investigating the role of immunotherapy in the first-line setting for advanced or recurrent endometrial cancer. RESULTS: The pooled data from 2320 patients across these trials substantiate the adoption of chemotherapy alongside immunotherapy, revealing a significant improvement in progression-free survival compared to chemotherapy alone [hazard ratio (HR) 0.70, 95% confidence interval (CI) 0.62-0.79] across all patient groups. Progression-free survival benefits are more pronounced in MMRd/MSI-H tumors (n = 563; HR 0.33, 95% CI 0.23-0.43). This benefit, albeit less robust, persists in the MMR-proficient/microsatellite stable group (n = 1757; HR 0.74, 95% CI 0.60-0.91). Pooled data further indicate that chemotherapy plus immunotherapy enhances overall survival compared to chemotherapy alone in all patients (HR 0.75, 95% CI 0.63-0.89). However, overall survival data maturity remains low. CONCLUSIONS: The incorporation of immunotherapy into the initial treatment for advanced and metastatic endometrial cancer brings about a substantial improvement in oncologic outcomes, especially within the MMRd/MSI-H subset. This specific subgroup is currently a focal point of investigation for evaluating the potential of chemotherapy-free regimens. Ongoing exploratory analyses aim to identify non-responding patients eligible for inclusion in clinical trials.

OBJECTIVES: The primary aim of this study was to develop and validate radiomics models, applied to ultrasound images, capable of differentiating from other cancers high-risk endometrial cancer, as defined jointly by the European Society for Medical Oncology, European Society of Gynaecological Oncology and European Society for Radiotherapy & Oncology (ESMO-ESGO-ESTRO) in 2016. The secondary aim was to develop and validate radiomics models for differentiating low-risk endometrial cancer from other endometrial cancers. METHODS: This was a multicenter, retrospective, observational study. From two participating centers, we identified consecutive patients with histologically confirmed diagnosis of endometrial cancer who had undergone preoperative ultrasound examination by an experienced examiner between 2016 and 2019. Patients recruited in Center 1 (Rome) were included as the training set and patients enrolled in Center 2 (Milan) formed the external validation set. Radiomics analysis (extraction of a high number of quantitative features from medical images) was applied to the ultrasound images. Clinical (including preoperative biopsy), ultrasound and radiomics features that were statistically significantly different in the high-risk group vs the other groups and in the low-risk group vs the other groups on univariate analysis in the training set were considered for multivariate analysis and for developing ultrasound-based machine-learning risk-prediction models. For discriminating between the high-risk group and the other groups, a random forest model from the radiomics features (radiomics model), a binary logistic regression model from clinical and ultrasound features (clinical-ultrasound model) and another binary logistic regression model from clinical, ultrasound and previously selected radiomics features (mixed model) were created. Similar models were created for discriminating between the low-risk group and the other groups. The models developed in the training set were tested in the validation set. The performance of the models in discriminating between the high-risk group and the other groups, and between the low-risk group and the other risk groups for both validation and training sets was compared. RESULTS: The training set comprised 396 patients and the validation set 102 patients. In the validation set, for predicting high-risk endometrial cancer, the radiomics model had an area under the receiver-operating-characteristics curve (AUC) of 0.80, sensitivity of 58.7% and specificity of 85.7% (using the optimal risk cut-off of 0.41); the clinical-ultrasound model had an AUC of 0.90, sensitivity of 80.4% and specificity of 83.9% (using the optimal cut-off of 0.32); and the mixed model had an AUC of 0.88, sensitivity of 67.3% and specificity of 91.0% (using the optimal cut-off of 0.42). For the prediction of low-risk endometrial cancer, the radiomics model had an AUC of 0.71, sensitivity of 65.0% and specificity of 64.5% (using the optimal cut-off of 0.38); the clinical-ultrasound model had an AUC of 0.85, sensitivity of 70.0% and specificity of 80.6% (using the optimal cut-off of 0.46); and the mixed model had an AUC of 0.85, sensitivity of 87.5% and specificity of 72.5% (using the optimal cut-off of 0.36). CONCLUSIONS: Radiomics seems to have some ability to discriminate between low-risk endometrial cancer and other endometrial cancers and better ability to discriminate between high-risk endometrial cancer and other endometrial cancers. However, the addition of radiomics features to the clinical-ultrasound models did not result in any notable increase in performance. Other efficacy studies and further effectiveness studies are needed to validate the performance of the models. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

OBJECTIVE: To develop and evaluate the performance of a radiomics and machine learning model applied to ultrasound (US) images in predicting the risk of malignancy of a uterine mesenchymal lesion. METHODS: Single-center retrospective evaluation of consecutive patients who underwent surgery for a malignant uterine mesenchymal lesion (sarcoma) and a control group of patients operated on for a benign uterine mesenchymal lesion (myoma). Radiomics was applied to US preoperative images according to the International Biomarker Standardization Initiative guidelines to create, validate and test a classification model for the differential diagnosis of myometrial tumors. The TRACE4 radiomic platform was used thus obtaining a full-automatic radiomic workflow. Definitive histology was considered as gold standard. Accuracy, sensitivity, specificity, AUC and standard deviation of the created classification model were defined. RESULTS: A total of 70 women with uterine mesenchymal lesions were recruited (20 with histological diagnosis of sarcoma and 50 myomas). Three hundred and nineteen radiomics IBSI-compliant features were extracted and 308 radiomics features were found stable. Different machine learning classifiers were created and the best classification system showed Accuracy 0.85 ± 0.01, Sensitivity 0.80 ± 0.01, Specificity 0.87 ± 0.01, AUC 0.86 ± 0.03. CONCLUSIONS: Radiomics applied to US images shows a great potential in differential diagnosis of mesenchymal tumors, thus representing an interesting decision support tool for the gynecologist oncologist in an area often characterized by uncertainty.

OBJECTIVE: The aim of this study was to investigate the correlation between BRCA mutational status and response to bevacizumab in a large advanced ovarian cancer (AOC) series. METHODS: This is a multicenter, retrospective case-control study including upfront AOC treated between January 2015 and June 2019. The main inclusion criteria were: having received three weekly carboplatin-paclitaxel as first-line treatment, with or without Bevacizumab maintenance, knowledge of the BRCA mutational status. RESULTS: Overall, 441 patients were included; 183 (41.5%) patients received bevacizumab (Cases), and 258 (58.5%) did not receive it (Controls). The BRCA mutated patients (BRCAmut) were 58 (39%) in the Cases group and 90 (34.9%) in the Controls group (p = .77). Patients who received bevacizumab had a significant 4-months increase in median progression free survival (mPFS: 21 vs. 17 months, p = .033). Concerning BRCAmut patients, no differences were shown between those who received bevacizumab or not in terms of mPFS (24 vs. 22 months, p = .3). Conversely, in BRCA wild-type (BRCAwt) population bevacizumab administration significantly prolonged mPFS (20 vs 15 months, p = .019). At multivariate analysis, independent factors of prolonged PFS were BRCA status (OR = 0.60), having received PDS (OR = 0.69), and complete cytoreduction (OR = 0.50), but not the bevacizumab administration (OR = 0.83, p = .22). CONCLUSIONS: No evidence of oncological benefit in terms of PFS and OS related to bevacizumab maintenance therapy was found in BRCAmut patients. Differently, BRCAwt patients seem to benefit from antiangiogenic treatment in terms of mPFS.

OBJECTIVE: To assess predictors of recurrence following laparoscopic radical hysterectomy (LRH) for apparent early stage cervical cancer (CC). METHODS: This is a retrospective multi-institutional study reviewing data of consecutive patients who underwent LRH for FIGO 2009 stage IA1 (with lymphovascular space invasion (LVSI)), IA2 and IB1(≤4 cm) CC, between January 2006 and December 2017. The following histotypes were included: squamous, adenosquamous, and adenocarcinoma. Multivariable models were used to estimate adjusted odds ratio (OR) and corresponding 95% CI. Factors influencing disease-free survival (DFS) and disease-specific survival (DSS) were also explored. RESULTS: 428 patients were included in the analysis. With a median follow-up of 56 months (1-162) 54 patients recurred (12.6%). At multivariable analysis, tumor size (OR:1.04, 95%CI:1.01-1.09, p = .02), and presence of cervical residual tumor at final pathology (OR: 5.29, 95%CI:1.34-20.76, p = .02) were found as predictors of recurrence; conversely preoperative conization reduced the risk (OR:0.32, 95%CI:0.11-0.90, p = .03). These predictors remained significant also in the IB1 subgroup: tumor size: OR:1.05, 95%CI:1.01-1.09, p = .01; residual tumor at final pathology: OR: 6.26, 95%CI:1.58-24.83, p = .01; preoperative conization: OR:0.33, 95%CI:0.12-0.95, p = .04. Preoperative conization (HR: 0.29, 95%CI: 0.13-0.91; p = .03) and the presence of residual tumor on the cervix at the time of surgery (HR: 8.89; 95%CI: 1.39-17.23; p = .01) independently correlated with DFS. No independent factors were associated with DSS. CONCLUSIONS: In women with early stage CC the presence of high-volume disease at time of surgery represent an independent predictor of recurrence after LRH. Conversely, preoperative conization and the absence of residual disease at the time of surgery might play a protective role.

BACKGROUND: Advanced recurrent ovarian cancer (ROC) is the leading cause of gynecologic cancer-related death in developed countries and new treatments are needed. Previous studies of immune checkpoint blockade showed low objective response rates (ORR) in ROC with no identified predictive biomarker. PATIENTS AND METHODS: This phase II study of pembrolizumab (NCT02674061) examined two patient cohorts with ROC: cohort A received one to three prior lines of treatment with a platinum-free interval (PFI) or treatment-free interval (TFI) between 3 and 12 months and cohort B received four to six prior lines with a PFI/TFI of ≥3 months. Pembrolizumab 200 mg was administered intravenously every 3 weeks until cancer progression, toxicity, or completion of 2 years. Primary end points were ORR by Response Evaluation Criteria in Solid Tumors version 1.1 per blinded independent central review by cohort and by PD-L1 expression measured as combined positive score (CPS). Secondary end points included duration of response (DOR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety. RESULTS: Cohort A enrolled 285 patients; the first 100 served as the training set for PD-L1 biomarker analysis. Cohort B enrolled 91 patients. ORR was 7.4% for cohort A and 9.9% for cohort B. Median DOR was 8.2 months for cohort A and not reached for cohort B. DCR was 37.2% and 37.4%, respectively, in cohorts A and B. Based on the training set analysis, CPS 1 and 10 were selected for evaluation in the confirmation set. In the confirmation set, ORR was 4.1% for CPS <1, 5.7% CPS ≥1, and 10.0% for CPS ≥10. PFS was 2.1 months for both cohorts. Median OS was not reached for cohort A and was 17.6 months for cohort B. Toxicities were consistent with other single-agent pembrolizumab trials. CONCLUSIONS: Single-agent pembrolizumab showed modest activity in patients with ROC. Higher PD-L1 expression was correlated with higher response.

OBJECTIVE: About 30% of Adult type granulosa cell tumors of the ovary (AGCTs) are diagnosed in fertile age. In stage I, conservative surgery (fertility-sparing surgery, FSS), either unilateral salpingo-oophorectomy (USO) or cystectomy are possible options. The aim of this study is to compare oncological outcomes of FSS and radical surgery (RS) in apparently stage I AGCTs treated within the MITO group (Multicenter Italian Trials in Ovarian cancer). METHODS: Survival curves were calculated using the Kaplan-Meier method and compared with log-rank test. The role of clinicopathological variables as prognostic factors for survival was assessed using Cox's regression. RESULTS: Two-hundred and twenty-nine patients were included; 32.6% received FSS, 67.4% RS. In the FSS group, 62.8% underwent USO, 16.7% cystectomy, 20.5% cystectomy followed by USO. After a median follow up of 84â¯months, median DFS was significantly worse in the FSS-group (10â¯yr DFS 50% vs 74%, in FSS and RS group, pâ¯=â¯0.006). No significant difference was detected between RS and USO (10â¯yr DFS 75% vs 70%, pâ¯=â¯0.5).Cystectomy-group showed a significantly worse DFS compared to USO (10â¯yr DFS 16% vs 70%, pâ¯<â¯0.001). Patients receiving cystectomy and subsequent USO showed a better prognosis, even though significantly worse compared to USO (10â¯yr DFS 41% vs 70%, pâ¯=â¯0.05). Between FSS and RS, no difference in OS was detected. At multivariate analysis, FIGO stage IC and cystectomy retained significant predictive value for worse survival. CONCLUSIONS: This study supports the oncological safety of FSS in stage I AGCTs, provided that cystectomy is avoided; USO should be the preferred approach.

Background: MITO-8 showed that prolonging platinum-free interval by introducing non-platinum-based chemotherapy (NPBC) does not improve prognosis of patients with partially platinum-sensitive recurrent ovarian cancer. Quality of life (QoL) was a secondary outcome. Patients and methods: Ovarian cancer patients recurring or progressing 6-12 months after previous platinum-based chemotherapy (PBC) were randomized to receive PBC or NPBC as first treatment. QoL was assessed at baseline, third and sixth cycles, with the EORTC C-30 and OV-28 questionnaires. Mean changes and best response were analysed. Progression-free survival, response rate, and toxicity are also reported for proper interpretation of data. All analyses were based on intention-to-treat. Results: Out of the 215 patients, 151 (70.2%) completed baseline questionnaire, balanced between the arms; thereafter, missing rate was higher in the NPBC arm. At mean change analysis, C30 scores were prevalently worse in the NPBC than PBC arm, statistical significance being attained for emotional functioning, global health status/QoL, fatigue, and dyspnoea (effect sizes ranging from 0.30 to 0.51). Conversely, as for OV28 scale, the other chemotherapy side-effects item was significantly worse with PBC at three and six cycles, with a larger effect size (0.70 and 0.54, respectively). At best response analysis, improvement of emotional functioning and pain and worsening of peripheral neuropathy and other chemotherapy side-effects were significantly more frequent in the PBC arm. Progression-free survival (median 9 versus 5 months, P = 0.001) and objective response rate (51.6% versus 19.4%, P = 0.0001) were significantly better with PBC. Allergy, blood cell count, alopecia, nausea, musculoskeletal, and neurological side-effects were more frequent and severe with PBC; hand-foot skin reaction, rash/desquamation, mucositis, and vascular events were more frequent with NPBC. Conclusion: MITO-8 QoL analysis shows that deterioration of some functioning and symptom scales is lower with PBC, with improvement of emotional functioning and pain, despite worsening of toxicity-related items.

BACKGROUND: To evaluate the influence of treatment on health-related quality of life (HRQoL) in 919 women with recurrent ovarian cancer enrolled in the TRINOVA-1 study, a randomized, placebo-controlled phase III study that demonstrated that trebananib 15 mg/kg QW plus weekly paclitaxel significantly improved progression-free survival (PFS) compared with placebo plus weekly paclitaxel (7.2 versus 5.4 months; hazard ratio, 0.66; 95% confidence interval 0.57-0.77; P < 0.001). PATIENTS AND METHODS: HRQoL was assessed with the Functional Assessment of Cancer Therapy-Ovary [FACT-O; comprising FACT-G and the ovarian cancer-specific subscale (OCS)] and EuroQOL EQ-5D instruments before treatment on day 1 of weeks 1, 5, 9, 13, 17, and every 8 weeks thereafter and at the safety follow-up visit. A pattern-mixture model was used to evaluate the influence of patient dropout on FACT-O and OCS scores over time. RESULTS: Of 919 randomized patients, 834 (91%) had a baseline and ≥1 post-baseline HRQoL assessment. At baseline, scores for all instruments were similar for both arms. At 25 weeks, mean ± SD changes from baseline were negligible, with mean ± SD changes typically <1 unit from baseline: -2.4 ± 16.6 in the trebananib arm and -1.6 ± 15.2 in the placebo arm for FACT-O, -0.71 ± 5.5 in the trebananib arm and -0.86 ± 4.9 in the placebo arm for OCS, and -0.02 ± 0.22 in the trebananib arm and 0.02 ± 0.19 in the placebo arm for EQ-5D. Distribution of scores was similar between treatment arms at baseline and over the course of the study. In pattern-mixture models, there was no evidence that patient dropout affected differences in mean FACT-O or OCS scores. Edema had limited effect on either FACT-O or OCS scores in patients with grade ≥2 edema or those with grade 1 or no edema. CONCLUSIONS: Our results demonstrate that the improvement in PFS among patients in the trebananib arm in the TRINOVA-1 study was achieved without compromising HRQoL.

BACKGROUND: Current evidence suggest that trabectedin is particularly effective in cells lacking functional homologous recombination repair mechanisms. A prospective phase II trial was designed to evaluate the activity of trabectedin in the treatment of recurrent ovarian cancer patients presenting BRCA mutation and/or BRCAness phenotype. PATIENTS AND METHODS: A total of 100 patients with recurrent BRCA-mutated ovarian cancer and/or BRCAness phenotype (≥2 previous responses to platinum) were treated with trabectedin 1.3 mg/mq i.v. q 3 weeks. The activity of the drug with respect to BRCA mutational status and to a series of polymorphisms [single-nucleotide polymorphisms (SNPs)] involved in DNA gene repair was analyzed. RESULTS: Ninety-four were evaluable for response; in the whole population, 4 complete and 33 partial responses were registered for an overall response rate (ORR) of 39.4. In the platinum-resistant (PR) and -sensitive (PS) population, an ORR of 31.2% and 47.8%, and an overall clinical benefit of 54.2% and 73.9%, respectively, were registered. In the whole series, the median progression-free survival (PFS) was 18 weeks and the median overall survival (OS) was 72 weeks; PS patients showed a more favorable PFS and OS compared with PR patients. BRCA gene mutational status was available in 69 patients. There was no difference in ORR, PFS and OS according to BRCA 1-2 status nor any association between SNPs of genes involved in DNA repair and NER machinery and response to trabectedin was reported. CONCLUSIONS: Our data prospectively confirmed that the signature of 'repeated platinum sensitivity' identifies patients highly responsive to trabectedin. In this setting, the activity of trabectedin seems comparable to what could be obtained using platinum compounds and the drug may represent a valuable alternative option in patients who present contraindication to receive platinum.

BACKGROUND: Data on CA-125 as a predictor of disease progression (PD) in ovarian cancer come predominantly from patients with platinum-sensitive disease receiving chemotherapy alone. We assessed concordance between CA-125-defined and RECIST-defined PD using data from the Gynecologic Cancer InterGroup (GCIG) randomized phase III AURELIA trial in platinum-resistant ovarian cancer (PROC). PATIENTS AND METHODS: Patients with PROC were randomized to receive single-agent chemotherapy with or without bevacizumab. PD by CA-125 was defined according to GCIG criteria (except that confirmatory CA-125 measurement was not required). This exploratory analysis included patients with RECIST PD and a CA-125 reading ≤28 days before and ≤21 days after RECIST-defined PD. RESULTS: Of 218 eligible patients, only 94 (43%, 95% confidence interval 36% to 50%) had concordant RECIST and CA-125 PD status (42% in the chemotherapy-alone arm; 45% in the bevacizumab combination arm, P = 0.6). There was no evidence of CA-125-defined PD in the remaining 124 patients despite PD according to imaging. There were no significant differences in baseline characteristics between patients with PD defined by both RECIST and CA-125 and those with RECIST-only PD. CA-125 was even less sensitive in detecting PD in patients with early (<8 weeks after randomization) compared with later RECIST-defined PD (69% versus 53%, respectively, not meeting CA-125 criteria; P = 0.053). There was no significant difference in survival after PD in patients with concordant PD by RECIST and CA-125 versus those with PD only by RECIST. We validated our findings in an independent study population of PROC. CONCLUSIONS: In this platinum-resistant population, PD was typically detected earlier by imaging than by CA-125, irrespective of bevacizumab treatment. Disease status by CA-125 at the time of PD was not prognostic for overall survival. Regular radiologic assessment as well as symptom benefit assessment should be considered during PROC follow-up.

OBJECTIVES: The objective of this study was to examine whether the oncologic outcomes of BRCA1-associated and BRCA2-associated ovarian cancers correlate differently. METHODS: Genetic data and clinical characteristics were correlated with progression-free survival (PFS) and overall survival (OS). RESULTS: Data from 147 BRCA-mutated patients (119 BRCA1-positive and 28 BRCA2-positive) were analyzed. At a median follow-up of 69 months, the median PFS was 27.2 and 45.46 months for BRCA1 and BRCA2 patients, respectively (p = 0.03). Median OS was 77.23 and 111.47 months for BRCA1 and BRCA2 patients, respectively (p = 0.08). CONCLUSION: BRCA2 mutations confer PFS and a trend to OS advantage compared with the BRCA1 mutation in BRCA-mutated epithelial ovarian cancer patients.

OBJECTIVES: This study was designed to investigate the response to chemotherapy of supradiaphragmatic disease diagnosed by preoperative imaging. As secondary objectives, oncologic outcomes of patients affected by supradiaphragmatic disease and their pattern of recurrence were also evaluated. METHODS: Data of consecutive patients with newly diagnosed FIGO stage IV (for supradiaphragmatic disease) epithelial ovarian cancer undergoing either primary debulking surgery or neoadjuvant chemotherapy plus interval debulking surgery between 2004 and 2021, were retrospectively collected. All patients were preoperatively evaluated by chest/abdominal CT scan or 18F-FDG PET/CT preoperatively and at follow-up to evaluate response to chemotherapy. At follow-up visits, site of recurrence diagnosed by imaging techniques was systematically recorded as it occurred. Progression-free and overall survival were measured by using Kaplan-Meier and Cox models. RESULTS: A total of 130 patients was included in this study with a median (range) follow-up of 32.9 (12.8-176.7) months. Complete or partial response was achieved in most of the patients after 3 cycles (77.7%) and 6 cycles (85.4%) of chemotherapy. At follow-up, recurrence occurred in 96 (73.8%) patients and the main site of recurrence was abdomen only in 64 (66.7%) patients. At multivariate analysis, residual disease after surgery was the only variable influencing survival outcomes. CONCLUSIONS: Supradiaphragmatic disease respond to chemotherapy in most patients affected by advanced EOC and recurrence mainly occurs in the abdomen. Results from this study confirms that abdominal optimal cytoreduction is the main surgical goal in the treatment of women affected by FIGO stage IV EOC.

BACKGROUND: Gatipotuzumab is a humanized monoclonal antibody recognizing the carbohydrate-induced epitope of the tumor-associated mucin-1 (TA-MUC1). This study aimed to evaluate the efficacy and safety of switch maintenance therapy with gatipotuzumab in patients with TA-MUC1-positive recurrent ovarian, fallopian tube, or primary high-grade serous peritoneal cancer. PATIENTS AND METHODS: In this double-blind, randomized, placebo-controlled, phase II trial, patients with at least stable disease (SD) following chemotherapy were randomized 2:1 to receive intravenous gatipotuzumab (500 mg followed by 1700 mg 1 week later) or placebo every 3 weeks until tumor progression or unacceptable toxicity occurred. Stratification factors were the number of prior chemotherapy lines (2 versus 3-5), response versus SD after the most recent chemotherapy, and progression-free survival (PFS) <6 versus 6-12 months following the prior therapy. Primary endpoint was PFS according to modified immune-related RECIST 1.1 response criteria. Secondary endpoints were PFS at 6 months, safety, overall response rate, CA-125 progression, overall survival, quality of life, and pharmacokinetics. RESULTS: Overall, 216 patients were randomized to gatipotuzumab (n = 151) or placebo (n = 65). Median PFS with gatipotuzumab was 3.5 months as compared with 3.5 months with placebo (hazard ratio 0.96, 95% confidence interval 0.69-1.33, P = 0.80). No advantage for gatipotuzumab over placebo was seen in the secondary efficacy endpoints or in any stratified subgroups. Gatipotuzumab was well tolerated, with mild to moderate infusion-related reactions being the most common adverse events. CONCLUSIONS: Gatipotuzumab switch maintenance therapy does not improve outcome in TA-MUC1-positive ovarian cancer patients.

BACKGROUND: The phase I GATTO study (NCT03360734) explored the feasibility, tolerability and preliminary activity of combining gatipotuzumab, a novel humanized monoclonal antibody binding to the tumor-associated epitope of mucin 1 (TA-MUC1) and an anti-epidermal growth factor receptor (anti-EGFR) antibody in refractory solid tumors. PATIENTS AND METHODS: Initially the study enrolled primary phase (PP) patients with EGFR-positive metastatic solid tumors, for whom no standard treatment was available. Patients received gatipotuzumab administered at 1400 mg every 2 weeks, 6 weeks after the start of the glyco-optimized anti-EGFR antibody tomuzotuximab at 1200 mg every 2 weeks. As this regimen was proven safe, enrollment continued in an expansion phase (EP) of patients with refractory metastatic colorectal cancer, non-small-cell lung cancer, head and neck cancer and breast cancer. Tomuzotuximab and gatipotuzumab were given at the same doses and gatipotuzumab treatment started 1 week after the first dose of the anti-EGFR antibody. Additionally, investigators could use a commercial anti-EGFR antibody in place of tomuzotuximab. RESULTS: A total of 52 patients were enrolled, 20 in the PP and 32 in the EP. The combined treatment was well tolerated and no dose-limiting toxicity was observed in the whole study, nor related serious adverse event or death. Preliminary activity of the combination was observed, with one and four RECIST partial responses in the PP and EP, all in colorectal cancer patients. The trial was accompanied by a comprehensive translational research program for identification of biomarkers, including soluble TA-MUC1 (sTA-MUC1) in serum. In the EP, patients with baseline sTA-MUC1 levels above the median appeared to have improved progression-free survival and overall survival. CONCLUSIONS: Combination of a TA-MUC1-targeting antibody and an EGFR-targeting antibody is safe and feasible. Interesting antitumor activity was observed in heavily pretreated patients. Future studies should test this combination together with chemotherapy and explore the potential of sTA-MUC1 as a companion biomarker for further development of the combination.

OBJECTIVE: The international acceptance of a universal classification system for radical hysterectomy is one of the important challenges in gynecologic oncology. The recently published classification system by Querleu and Morrow is a relevant proposal that has been well received by the professional community. However, it does not include a description of parametrial resection in three dimensions, which mostly determines post-operative morbidity. METHODS: The intention of this follow-up paper was to further develop the classification system based on the four proposed types of radical hysterectomy (A-D) into a three-dimensional model using standard anatomical landmarks for definition of resection margins in longitudinal and transverse dimensions and demonstrate it on pictures. RESULTS: Resection margins were defined in longitudinal and transverse dimensions for each suggested type of radical hysterectomy on all three parts of the parametria. Besides precise description using stable anatomical landmarks, all resection lines have been shown on intra-operative photographs. CONCLUSION: Four types of radical hysteretomy can be precisely defined on a three-dimensional anatomical template, including nerve sparing procedure. Our paper should contribute to better standardization (including nomenclature) of the radical hysterectomy, enhancing harmonization of clinical practice in gynecological oncology.

BACKGROUND: The management of cervical cancer patients with intraoperative detection of lymph node involvement remains controversial. Since all these patients are referred for (chemo)radiation after the surgery, the key decision is whether radical hysterectomy should be completed as originally planned, taking into account an additional morbidity associated with extensive surgical dissection prior to adjuvant treatment. The ABRAX study investigated whether completing a radical uterine procedure is associated with an improved oncological outcome of such patients. PATIENTS AND METHODS: We performed retrospective analyses of 515 cervical cancer patients (51 institutions, 19 countries) who were referred for primary curative surgery between 2005 and 2015 (stage IA-IIB, common tumour types) in whom lymph node involvement was detected intraoperatively. Patients were stratified according to whether the planned uterine surgery was completed (COMPL group, N = 361) or abandoned (ABAND group, N = 154) to compare progression-free survival. Definitive chemoradiation was given to 92.9% patients in the ABAND group and adjuvant (chemo)radiation or chemotherapy to 91.4% of patients in the COMPL group. RESULTS: The risks of recurrence (hazard ratio [HR] 1.154, 95% confidence intervals [CI] 0.799-1.666, P = 0.45), pelvic recurrence (HR 0.836, 95% CI 0.458-1.523, P = 0.56), or death (HR 1.064, 95% CI 0.690-1.641, P = 0.78) were not significantly different between the two groups. No subgroup showed a survival benefit from completing radical hysterectomy. Disease-free survival reached 74% (381/515), with a median follow-up of 58 months. Prognostic factors were balanced between the two groups. FIGO stage and number of pelvic lymph nodes involved were significant prognostic factors in the whole study cohort. CONCLUSION: We showed that the completion of radical hysterectomy does not improve survival in patients with intraoperatively detected lymph node involvement, regardless of tumour size or histological type. If lymph node involvement is confirmed intraoperatively, abandoning uterine radical procedure should be considered, and the patient should be referred for definitive chemoradiation.

OBJECTIVE: Surgery represents the mainstay of treatment of stage I adult type granulosa cell tumors of the ovary (AGCTs). Because of the rarity and indolent course of the disease, no prospective trials are available. Open surgery has long been considered the traditional approach; oncological safety of laparoscopy is only supported by small series or case reports. The aim of this study was to compare the oncological outcomes between laparoscopic and open surgery in stage I AGCTs treated within the MITO (Multicenter Italian Trials in Ovarian cancer) Group. METHODS: Data from patients with stage I AGCTs were retrospectively collected. Clinicopathological features were evaluated for association with relapse and death. Survival curves were calculated using the Kaplan-Meier method and compared with the log-rank test. The role of clinicopathological variables as prognostic factors for survival was evaluated using Cox's regression model. RESULTS: 223 patients were identified. Stage 1A, 1B and 1C were 61.5%, 1.3% and 29.6% respectively. 7.6% were apparently stage I. Surgical approach was laparoscopic for 93 patients (41.7%) and open for 130 (58.3%). 5-years DFS was 84% and 82%, 10-years DFS was 68% and 64% for the laparoscopic and open-group (p = 0.6).5-years OS was 100% and 99%, 10 years OS was 98% and 97% for the laparoscopic and open-surgery group (p = 0.8). At multivariate analyses stage IC, incomplete staging, site of primary surgery retained significant prognostic value. CONCLUSION: The present study suggests that surgical route does not affect the oncological safety of patients with stage I AGCTs, with comparable outcomes between laparoscopic and open approach.
