RESUMO
PURPOSE: Large cell neuroendocrine carcinoma (LCNEC) is a high-grade neuroendocrine malignancy that, like small cell lung cancer (SCLC), is associated with an absence of druggable oncogenic drivers and dismal prognosis. In contrast to SCLC, however, there is little evidence to guide optimal treatment strategies which are often adapted from SCLC and non-small cell lung cancer (NSCLC) approaches. EXPERIMENTAL DESIGN: To better define the biology of LCNEC, we analyzed cell line and patient genomic data and performed immunohistochemistry and single-cell (sc)RNAseq of core needle biopsies from LCNEC patients and preclinical models. RESULTS: Here, we demonstrate that the presence or absence of YAP1 distinguishes two subsets of LCNEC. The YAP1-high subset is mesenchymal and inflamed and characterized, alongside TP53 mutations, by co-occurring alterations in CDKN2A/B and SMARCA4. Therapeutically, the YAP1-high subset demonstrates vulnerability to MEK and AXL targeting strategies, including a novel preclinical AXL CAR-T cell. Meanwhile, the YAP1-low subset is epithelial and immune-cold and more commonly features TP53 and RB1 co-mutations, similar to those observed in pure SCLC. Notably, the YAP1-low subset is also characterized by expression of SCLC subtype-defining transcription factors - especially ASCL1 and NEUROD1 - and, as expected given its transcriptional similarities to SCLC, exhibits putative vulnerabilities reminiscent of SCLC, including Delta-like ligand 3 (DLL3) and CD56 targeting, as with novel preclinical DLL3 and CD56 CAR T-cells, and DNA damage repair (DDR) inhibition. CONCLUSION: YAP1 defines distinct subsets of LCNEC with unique biology. These findings highlight the potential for YAP1 to guide personalized treatment strategies for LCNEC.
RESUMO
Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.The aim of this study was to compare overall survival between open and minimally invasive radical hysterectomy with participants followed for 4.5 years. The primary objective was to evaluate whether minimally invasive surgery was noninferior in disease-free survival (DFS) to abdominal radical hysterectomy. Secondary outcomes included overall survival. Sample size was based on DFS of 90% at 4.5 years and 7.2% noninferiority margin for minimally invasive surgery. A total of 631 patients were enrolled: 319 assigned to minimally invasive and 312 to open surgery. Of these, 289 (90.6%) patients underwent minimally invasive surgery and 274 (87.8%) patients open surgery. At 4.5 years, DFS was 85.0% in the minimally invasive group and 96% in the open group (difference of -11.1; 95% CI, -15.8 to -6.3; P = .95 for noninferiority). Minimally invasive surgery was associated with lower rate of DFS compared with open surgery (hazard ratio [HR], 3.91 [95% CI, 2.02 to 7.58]; P < .001). Rate of overall survival at 4.5 years was 90.6% versus 96.2% for the minimally invasive and open surgery groups, respectively (HR for death of any cause = 2.71 [95% CI, 1.32 to 5.59]; P = .007). Given higher recurrence rate and worse overall survival with minimally invasive surgery, an open approach should be standard of care.

OBJECTIVE: The purpose of this study was to establish a consensus on the surgical technique for sentinel lymph node (SLN) dissection in cervical cancer. METHODS: A 26 question survey was emailed to international expert gynecological oncology surgeons. A two-step modified Delphi method was used to establish consensus. After a first round of online survey, the questions were amended and a second round, along with semistructured interviews was performed. Consensus was defined using a 70% cut-off for agreement. RESULTS: Twenty-five of 38 (65.8%) experts responded to the first and second rounds of the online survey. Agreement ≥70% was reached for 13 (50.0%) questions in the first round and for 15 (57.7%) in the final round. Consensus agreement identified 15 recommended, three optional, and five not recommended steps. Experts agreed on the following recommended procedures: use of indocyanine green as a tracer; superficial (with or without deep) injection at 3 and 9 o'clock; injection at the margins of uninvolved mucosa avoiding vaginal fornices; grasping the cervix with forceps only in part of the cervix is free of tumor; use of a minimally invasive approach for SLN biopsy in the case of simple trachelectomy/conization; identification of the ureter, obliterated umbilical artery, and external iliac vessels before SLN excision; commencing the dissection at the level of the uterine artery and continuing laterally; and completing dissection in one hemi-pelvis before proceeding to the contralateral side. Consensus was also reached in recommending against injection at 6 and 12 o'clock, and injection directly into the tumor in cases of the tumor completely replacing the cervix; against removal of nodes through port without protective maneuvers; absence of an ultrastaging protocol; and against modifying tracer concentration at the time of re-injection after mapping failure. CONCLUSION: Recommended, optional, and not recommended steps of SLN dissection in cervical cancer have been identified based on consensus among international experts. These represent a surgical guide that may be used by surgeons in clinical trials and for quality assurance in routine practice.

PURPOSE: The aim of this review is to give an overview of the current status of molecular image-guided surgery in gynaecological malignancies, from both clinical and technological points of view. METHODS: A narrative approach was taken to describe the relevant literature, focusing on clinical applications of molecular image-guided surgery in gynaecology, preoperative imaging as surgical roadmap, and intraoperative devices. RESULTS: The most common clinical application in gynaecology is sentinel node biopsy (SNB). Other promising approaches are receptor-target modalities and occult lesion localisation. Preoperative SPECT/CT and PET/CT permit a roadmap for adequate surgical planning. Intraoperative detection modalities span from 1D probes to 2D portable cameras and 3D freehand imaging. CONCLUSION: After successful application of radio-guided SNB and SPECT, innovation is leaning towards hybrid modalities, such as hybrid tracer and fusion of imaging approaches including SPECT/CT and PET/CT. Robotic surgery, as well as augmented reality and virtual reality techniques, is leading to application of these innovative technologies to the clinical setting, guiding surgeons towards a precise, personalised, and minimally invasive approach.

BACKGROUND: Few studies have evaluated the role of cytoreductive surgery in patients with recurrent adult granulosa cell tumors of the ovary. Despite a multitude of treatment modalities in the recurrent setting, the optimal management strategy is not known. Cytoreductive surgery offers an attractive option for disease confined to the abdomen/pelvis. However, few studies have evaluated the role of surgery compared with systemic therapy alone following the first recurrence and subsequent disease progressions. OBJECTIVE: This study aimed to determine the impact of secondary, tertiary, and quaternary cytoreductive surgery on survival outcomes in recurrent adult granulosa cell tumors of the ovary. STUDY DESIGN: This is a multicenter, retrospective cohort study evaluating patients with recurrent adult granulosa cell tumors of the ovary enrolled in the MD Anderson Rare Gynecologic Malignancy Registry from 1970 to 2022. Study inclusion criteria consisted of histology-proven recurrent disease, at least 1 documented recurrence, and treatment/treatment planning at the MD Anderson Cancer Center or Lyndon B. Johnson General Hospital. The primary exposure was cytoreductive surgery, and the outcomes of interest were progression-free survival and overall survival. Survival analyses were restricted to eligible patients with resectable disease without medical barriers to surgery at each progression episode. Demographic and clinicopathologic characteristics were summarized using descriptive statistics. Progression-free survival (after first, second, and third progression) and overall survival were estimated with methods of Kaplan and Meier, and were modeled via Cox proportional hazards regression. Multivariable analyses were performed for progression-free survival after first progression and overall survival. RESULTS: Among the 369 patients with adult granulosa cell tumors of the ovary in the registry, 149 patients met the study inclusion criteria. Secondary cytoreductive surgery was associated with a significant improvement in progression-free survival on univariable (hazard ratio, 0.37; 95% confidence interval, 0.17-0.81, P=.01) and multivariable analyses (hazard ratio, 0.42; 95% confidence interval, 0.19-0.92; P=.03). Those who underwent secondary cytoreductive surgery had a significantly improved median overall survival compared with those who did not undergo cytoreductive surgery (181.92 vs 61.56 months, respectively; P=.002). Overall survival benefit remained statistically significant on multivariable analysis (hazard ratio, 0.28; 95% confidence interval, 0.11-0.67; P=.004). Tertiary cytoreductive surgery was similarly associated with a significant improvement in progression-free survival (hazard ratio, 0.43; 95% confidence interval, 0.26-0.70; P=.001). Despite a similar trend, quaternary cytoreductive surgery was not associated with a significant improvement in progression-free survival (hazard ratio, 0.74; 95% confidence interval, 0.42-1.26; P=.27). CONCLUSION: Among those with resectable disease and no medical contraindications to surgery, cytoreductive surgery may have a beneficial impact on progression-free survival and overall survival in patients with recurrent adult granulosa cell tumors of the ovary.

OBJECTIVE: To describe the clinicopathological characteristics and survival outcomes of ovarian neuroendocrine neoplasms from a curated registry. METHODS: This is a retrospective cross-sectional study of patients in our registry with confirmed ovarian neuroendocrine neoplasms. We excluded patients with small cell carcinoma not otherwise specified, small cell hypercalcemic type, and those with neuroendocrine 'features' or 'differentiation.' Clinicopathological characteristics were described in two separate groups: patients with carcinoid tumors and patients with neuroendocrine carcinomas. Progression-free and overall survival were estimated with the Kaplan-Meier product-limit estimator in these two groups, and multivariable analysis was done to identify predictors of survival for neuroendocrine carcinomas only. RESULTS: A total of 63 patients met inclusion criteria, 13 (21%) with carcinoid tumors and 50 (79%) with neuroendocrine carcinomas. In the carcinoid tumor group, one patient (8%) was misdiagnosed. Two patients (15%) had a recurrence and the 5-year overall survival rate was 80% (95% CI 45% to 100%), with a lower bound of the median survival of 4.8 years (95% CI). In the neuroendocrine carcinoma group, 23 patients (46%) were misdiagnosed, 16 of whom (69%) received therapy with the presumption of a non-neuroendocrine carcinoma diagnosis. Thirty patients (60%) had a recurrence, and the 5-year overall survival rate was 24% (10%, 38%), with a median survival of 1.6 years (1.3, 3.3). Patients with carcinomas stage III or IV had an increased risk of progression/recurrence (HR=5.6; 95% CI 1.9 to 17.0) and death (HR=8.1; 95% CI 2.2 to 29.7) compared with those with stage I or II. Pure histology was associated with an increased risk of progression/recurrence (HR=2.3; 95% CI 1.0 to 5.2) compared with admixed histology. CONCLUSION: Most patients had neuroendocrine carcinomas, which were associated with a higher recurrence rate and worse survival than carcinoid tumors. A high proportion of patients in both groups were initially misdiagnosed, and a new association with endometrial hyperplasia was observed. Neuroendocrine admixed histology is associated with a higher risk of progression.

INTRODUCTION: The objective of this study was to assess differences in long-term sexual and menopausal side effects after uterine cancer treatment among treatment modalities. METHODS AND MATERIALS: This is a cross-sectional study that examined women treated for uterine cancer from 2006-2018. Eligible women included those who underwent a hysterectomy/bilateral salpino-oophorectemy alone (HS), with brachytherapy (BT), or with external beam radiation therapy (EBRT). A noncancer cohort of women who underwent a hysterectomy/BSO for benign indications were also identified (non-CA). To compare outcomes, we utilized a shortened form of the female sexual function index (FSFI) and the menopause survey, which consists of 3 subscales: hot flashes, vaginal symptoms, and urinary symptoms. Demographic, comorbidity, and other treatment variables were collected. Survey totals were compared across cohorts using ANOVA tests and logistic regression. RESULTS: A total of 284 women completed the Menopause Survey (Non-CA 64, HS 60, BT 69, EBRT 91); 116 women reported sexual activity in the last 4 weeks and completed the FSFI (NC 32, HS 21, BT 31, EBRT 32). The mean FSFI score for the entire cohort was 11.4 (SD 4.16), which indicates poor sexual function. There was no significant difference between any cohort in the overall FSFI score (pâ¯=â¯0.708) or in any of the FSFI subscales (all p > 0.05). On univariate analysis, BT was associated with fewer menopausal hot flashes and vaginal symptoms compared to the non-CA cohort (p < 0.05), which did not persist on multivariable analysis. CONCLUSION: There was no significant difference in sexual dysfunction or menopausal symptoms in those treated for uterine cancer with or without adjuvant radiation. Most patients reported poor sexual function.

OBJECTIVE: The impact of adjuvant pelvic radiation therapy on the rate and location of recurrences was evaluated in patients with early-stage (IA1-IB2) neuroendocrine cervical carcinoma who underwent prior conization or polypectomy with no residual disease and negative nodes in the subsequent upfront radical hysterectomy specimen. As a secondary objective, disease-free and overall survival were analyzed. METHODS: We searched the Neuroendocrine Cervical Tumor Registry (NeCTuR) to identify patients with clinical early-stage neuroendocrine cervical carcinoma with no residual disease in the specimen from upfront radical surgery and negative nodes. Patients who received pelvic radiation therapy were compared with those who did not, regardless of whether they received adjuvant chemotherapy. RESULTS: Twenty-seven patients met the inclusion criteria, representing 17% of all patients with clinical early-stage disease who underwent upfront radical hysterectomy included in the NeCTuR registry. The median age was 36.0 years (range 26.0-51.0). Six (22%) patients had stage IA, 20 (74%) had stage IB1, and one (4%) had stage IB2 disease. Seven (26%) patients received adjuvant radiation therapy and 20 (74%) did not. All seven patients in the radiation group and 14 (70%) in the no-radiation group received adjuvant chemotherapy (p=0.16). Fifteen percent (4/27) of patients had a recurrence, 14% (1/7) in the radiation group and 15% (3/20) in the no-radiation group (p=0.99). In the radiation group the recurrence was outside the pelvis, and in the no-radiation group, 67% (2/3) recurred outside the pelvis and 33% (1/3) recurred both inside and outside the pelvis (p=0.99). In the radiation group the 5-year disease-free and overall survival rates were 100% while, in the no-radiation group, the 5-year disease-free and overall survival rates were 81% (95% CI 61% to 100%) (p=0.99) and 80% (95% CI 58% to 100%) (p=0.95), respectively. CONCLUSIONS: For patients with no residual disease and negative nodes in the upfront radical hysterectomy specimen, our study did not find that pelvic radiation therapy improves survival.
RESUMO
OBJECTIVE: To evaluate the detection rate of at least one sentinel lymph node (SLN) in patients with early cervical cancer who underwent open radical hysterectomy or trachelectomy using indocyanine green (ICG) with the SPY Portable Handler Imager (SPY-PHI) system. METHODS: We retrospectively reviewed patients with cervical cancer FIGO 2018 stage IA1 with lymphovascular invasion up to stage IIIC1p who underwent SLN mapping and open radical hysterectomy or trachelectomy from March 2018 through August 2022 at The University of Texas MD Anderson Cancer Center. ICG was the only tracer used with the SPY-PHI system. Patient demographics, surgical approach, and tumor factors were analyzed. Overall detection, bilateral detection, and empty lymph node packet rates were determined. RESULTS: A total of 106 patients were included. Ninety-four (88.7%) patients underwent open radical hysterectomy and 12 (11.3%) open radical trachelectomy. Median age was 40 years (range, 23-71). Median body mass index was 28.8 kg/m2 (range, 17.6-48.4). The most common FIGO 2018 stages were IB1 (35%) and IB2 (30%). The most common histologic subtypes were squamous cell carcinoma (45%) and adenocarcinoma (45%). Most patients had grade 2 disease (61%) and no lymphovascular invasion (58%). Median tumor size was 1.8 cm (range, 0.3-4). Median number of detected SLN was 4 (range, 0-12). An SLN was identified during surgery in 104 patients (98%), with bilateral mapping in 94 (89%) and unilateral mapping in 10 (9%). The empty lymph node packet rate was 4 (3.8%). The external iliac (73%) was the most common site of SLN detection. Fourteen patients had positive lymph nodes (13.5%); 3 (21.4%) had macrometastases, 9 (64.3%) had micrometastases, and 2 (14.3%) had isolated tumor cells. CONCLUSION: SLN mapping using ICG with the SPY-PHI system in open radical hysterectomy or trachelectomy is reliable and results in high overall and bilateral detection rates in patients with early cervical cancer.
RESUMO
OBJECTIVE: To determine the optimal imaging modality for women with high-grade neuroendocrine carcinoma of the cervix. METHODS: Women with high-grade neuroendocrine carcinoma of the cervix who had undergone a computed tomography (CT) scan and combined positron emission tomography with computed tomography (PET/CT) scan within 4 weeks of each other were identified from the NeCTuR Cervical Tumor Registry. One radiologist reviewed all CT scans, and another radiologist reviewed all PET/CT scans. The radiologists denoted the presence or absence of disease at multiple sites. Each radiologist was blinded to prior reports, patient outcomes, and the readings of the other radiologist. With findings on PET/CT used as the gold standard, sensitivity, specificity, and accuracy were calculated for CT scans. RESULTS: Fifty matched CT and PET/CT scans were performed in 41 patients. For detecting primary disease in the cervix, CT scan had a sensitivity of 85%, a specificity of 46%, and an accuracy of 74%. For detecting disease spread to the liver, CT scan had a sensitivity of 80%, a specificity of 89%, and an accuracy of 86%. For detecting disease spread to the lung, CT had a sensitivity of 89%, a specificity of 68%, and an accuracy of 77%. Of the 14 patients who had scans for primary disease work-up, 4 (29%) had a change in their treatment plan due to the PET/CT scan. Had treatment been prescribed on the basis of the CT scan alone, 2 patients would have been undertreated, and 2 would have been overtreated. CONCLUSION: A CT scan is inferior to a PET/CT scan in assessment of metastatic disease in women with high-grade neuroendocrine carcinoma of the cervix. Almost one-third of patients with newly diagnosed high-grade neuroendocrine cervical cancer would have received incorrect therapy had treatment planning been based solely on a CT scan. We recommend a PET/CT scan for both initial work-up and surveillance in women with high-grade neuroendocrine carcinoma of the cervix.

Mucosal melanoma remains a rare cancer with high mortality and a paucity of therapeutic options. This is due in significant part to its low incidence leading to limited patient access to expert care and downstream clinical/basic science data for research interrogation. Clinical challenges such as delayed and at times inaccurate diagnoses, and lack of consensus tumor staging have added to the suboptimal outcomes for these patients. Clinical trials, while promising, have been difficult to activate and accrue. While individual institutions and investigators have attempted to seek solutions to such problems, international, national, and local partnership may provide the keys to more efficient and innovative paths forward. Furthermore, a mucosal melanoma coalition would provide a potential network for patients and caregivers to seek expert opinion and advice. The Melanoma Research Foundation Mucosal Melanoma Meeting (December 16, 2022, New York, USA) highlighted the current clinical challenges faced by patients, providers, and scientists, identified current and future clinical trial investigations in this rare disease space, and aimed to increase national and international collaboration among the mucosal melanoma community in an effort to improve patient outcomes. The included proceedings highlight the clinical challenges of mucosal melanoma, global clinical trial experience, basic science advances in mucosal melanoma, and future directions, including the creation of shared rare tumor registries and enhanced collaborations.

OBJECTIVE: Neuroendocrine cervical carcinoma (NECC) is rare. Educational resources are limited for NECC patients, leading many to seek information online through patient-led social networks. We sought to characterize the relationships between anxiety and depression levels and social media use among NECC patients. METHODS: Seven surveys assessing social media use, anxiety, and depression were distributed to living NECC patients enrolled in our NECC registry. The primary outcomes were associations between Social Network Time Use Scale (SONTUS) global score and Generalized Anxiety Disorder (GAD-7) and Center for Epidemiologic Studies Depression Scale (CESD) total scores. RESULTS: Eighty-eight patients enrolled; 81 who completed at least 1 survey were included. Ninety-seven percent (70/72) of patients completing SONTUS were low-to-average social media users. Seventy-four percent (53/72) of patients visited a patient-led NECC support-group page on Facebook within the past 4 weeks, and of those, 79% (42/53) reported receiving useful information. Among the patients who did not visit the page, 47% (9/19) reported that the page elicited anxiety and/or sadness. The mean GAD-7 and CES-D scores for the entire cohort were 7.3 and 18.1, respectively. The Spearman correlations between social media use and these scores were significant (GAD-7: 0.23 [p = 0.05]; CESD: 0.25 [p = 0.04]). The estimated odds ratios for moderate/severe anxiety and depression as a function of SONTUS global score were 1.26 (95% CI 1.03-1.55; p = 0.03) and 1.23 (95% CI 1.01-1.49; p = 0.04), respectively. CONCLUSIONS: NECC patients demonstrated low-to-average social media use and relatively high anxiety and depression. Increased social media use was associated with elevated anxiety and depression.
RESUMO
OBJECTIVE: To evaluate clinicopathologic features and oncologic outcomes of patients with neuroendocrine cervical carcinoma in an institutional neuroendocrine cervical tumor registry. METHODS: Retrospective study including patients with neuroendocrine cervical carcinomas diagnosed between 1986 and 2022. Patients were categorized into International Federation of Gynecology and Obstetrics 2018 stage groups: early-stage (IA1-IB2, IIA1); locally advanced (IB3, IIA2-IVA); and advanced (IVB). Clinicopathologic characteristics and oncologic outcomes were evaluated by stage. Survival was compared between patients diagnosed in 1986-2003 and those diagnosed in 2004-2016. Progression-free and overall survival were estimated using the Kaplan-Meier product-limit estimator. RESULTS: A total of 453 patients was included, 133 (29%) with early-stage, 226 (50%) with locally advanced, and 94 (21%) with advanced disease. Median age was 38 years (range 21-93). Sixty-nine percent (306/453) had pure and 32% (146/453) had mixed histology. The node positivity rate (surgical or radiological detection) was 19% (21/108) for tumors ≤2 cm, 37% (39/105) for tumors >2 to ≤4 cm, and 61% (138/226) for tumors >4 cm (p<0.0001). After primary treatment, rates of complete response were 86% (115/133) for early-stage, 65% (147/226) for locally advanced, and 19% (18/94) for advanced disease (p<0.0001). The recurrence/progression rate was 43% for early-stage, 69% for locally advanced, and 80% for advanced disease (p<0.0001). Five-year progression-free and overall survival rates were 59% (95% CI 50% to 68%) and 71% (95% CI 62% to 80%), respectively, for early-stage, 28% (95% CI 22% to 35%) and 36% (95% CI 29% to 43%), respectively, for locally advanced, and 6% (95% CI 0% to 11%) and 12% (95% CI 5% to 19%), respectively, for advanced disease. For early-stage disease, the 5-year progression-free survival rate was 68% for tumors ≤2 cm and 43% for tumors >2 to ≤4 cm (p=0.0013). Receiving cisplatin/carboplatin plus etoposide (HR=0.33, 95% CI 0.17 to 0.63, p=0.0008) and receiving curative radiotherapy (HR=0.32, 95% CI 0.17 to 0.6, p=0.0004) were positive predictors of survival for patients with advanced disease. CONCLUSION: Among patients with neuroendocrine cervical carcinomas, overall survival is favorable for patients with early-stage disease. However, most patients present with locally advanced disease, and overall survival remains poor in this subgroup. For patients with advanced disease, receiving cisplatin/carboplatin plus etoposide and curative radiation therapy is associated with improved overall survival.

High-grade neuroendocrine neoplasms are a rare disease entity and account for approximately 10% of all neuroendocrine neoplasms. Because of their rarity, there is an overall lack of prospectively collected data available to advise practitioners as to how best to manage these patients. As a result, best practices are largely based on expert opinion. Recently, a distinction was made between well-differentiated high-grade (G3) neuroendocrine tumors and poorly differentiated neuroendocrine carcinomas, and with this, pathologic details, appropriate imaging practices and treatment have become more complex. In an effort to provide practitioners with the best guidance for the management of patients with high-grade neuroendocrine neoplasms of the gastrointestinal tract, pancreas, and gynecologic system, the North American Neuroendocrine Tumor Society convened a panel of experts to develop a set of recommendations and a treatment algorithm that may be used by practitioners for the care of these patients. Here, we provide consensus recommendations from the panel on pathology, imaging practices, management of localized disease, management of metastatic disease and surveillance and draw key distinctions as to the approach that should be utilized in patients with well-differentiated G3 neuroendocrine tumors vs poorly differentiated neuroendocrine carcinomas.

Extrauterine mesonephric-like carcinoma (ExUMLC) shares histologic, immunohistochemical (IHC), and molecular (MOL) features with endometrial mesonephric-like carcinoma (EnMLC). Its rarity and histologic overlap with Mullerian carcinomas contribute to underrecognition of ExUMLC. Aggressive behavior of EnMLC is well-documented; behavior of ExUMLC is yet to be characterized. This study presents the clinicopathologic, IHC, and MOL features of 33 ExUMLC identified over a 20-year time period (2002-2022) and compares the behavior of this cohort to more common upper gynecologic Mullerian carcinomas (low-grade endometrioid, LGEC; clear cell, CCC; high-grade serous, HGSC) and EnMLC diagnosed over the same time period. ExUMLC patients ranged from 37 to 74 years old (median=59 y); 13 presented with advanced stage (FIGO III/IV) disease. Most ExUMLC had the characteristic mixture of architectural patterns and cytologic features, as previously described. Two ExUMLC had sarcomatous differentiation, 1 with heterologous rhabdomyosarcoma. Twenty-one ExUMLC (63%) had associated endometriosis, and 7 (21%) arose in a borderline tumor. In 14 (42%) cases, ExUMLC was part of a mixed carcinoma representing >50% of the tumor in 12. Twenty-six cases (79%) were incorrectly classified as follows: LGEC or HGEC (12); adenocarcinoma, not otherwise specified (3); HGSC (3); LGSC (2); mixed carcinoma (1); carcinosarcoma, Mullerian type (2); seromucinous carcinoma (1); transitional pattern of HGSC (1); and female adnexal tumor of probable Wolffian origin (1). Three patients had occult synchronous endometrial LGEC. IHC facilitated diagnosis in all cases with an expression of GATA-3 and/or TTF-1 in conjunction with decreased hormone receptor expression in most tumors. MOL testing (n=20) identified a variety of mutations, most frequently: KRAS (15); TP53 (4); SPOP (4); and PIK3CA (4). ExUMLC and CCC were more likely to be associated with endometriosis ( P <0.0001). ExUMLC and HGSC had more recurrences compared with CCC and LGEC ( P <0.0001). Histologic subtype was associated with longer disease-free survival for LGEC and CCC versus HGSC and ExUMLC ( P <0.001). ExUMLC trended towards a similar poor overall survival as HGSC compared with LGEC and CCC, and EnMLC trended to shorter survival compared with ExUMLC. Neither finding reached significance. No differences were seen between EnMLC and ExUMLC with respect to presenting stage or recurrence. Staging, histotype, and endometriosis were associated with disease-free survival, but on multivariate analysis, only stage remained as an independent predictor of outcome. The tendency of ExUMLC to present at an advanced stage and have distant recurrence points to more aggressive behavior compared with LGEC with which it is most frequently confused, underscoring the importance of an accurate diagnosis.

BACKGROUND: Advanced or recurrent primary mucinous ovarian cancer is typically incurable and associated with short progression-free and overall survival when treated with standard chemotherapy. Novel approaches are desperately needed for women with this disease. CASES: Two patients with advanced or recurrent primary mucinous ovarian cancer were treated with secondary cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC). No additional chemotherapy was administered postoperatively. Both patients achieved a complete and durable response, with no evidence of recurrence at 21 and 27 months, respectively, after CRS with HIPEC. CONCLUSION: Secondary CRS with HIPEC represents a potential therapeutic option for women with recurrent primary mucinous ovarian cancer.

BACKGROUND: Human papillomavirus (HPV) types 16/18 drive oncogenesis for most patients with cervical, anal, and penile cancers. MEDI0457, a therapeutic DNA vaccine containing plasmids for E6 and E7 HPV-16/18 viral oncogenes and IL-12 adjuvant, is safe and provokes an immune response against E6/E7. We tested MEDI0457 with the anti-PD-L1 antibody durvalumab for patients with HPV-associated cancers. METHODS: Patients with recurrent/metastatic, treatment-refractory HPV-16/18 cervical cancer, or rare HPV-associated (anal and penile) cancers were eligible. Prior immune checkpoint inhibition was not permitted. Patients received MEDI0457 7 mg intramuscularly (weeks 1, 3, 7, 12, and every 8 weeks thereafter) and durvalumab 1500 mg intravenously every 4 weeks. The primary endpoint was overall response (RECIST 1.1). In this Simon two-stage phase 2 trial (Ho: pâ <â 0.15; Ha: pâ ≥â 0.35), ≥2 responses were needed in both cervical and non-cervical cohorts during the first stage for the trial to proceed to stage 2 with an additional 25 patients (34 total) enrolled. RESULTS: Twenty-one patients (12 cervical, 7 anal, and 2 penile) were evaluable for toxicity and 19 for response Overall response rate was 21% (95% CI, 6%-46%) among evaluable patients. Disease control rate was 37% (95% CI, 16%-62%). Median duration of response among responders was 21.8 months (95% CI, 9.7%-not estimable). Median progression-free survival was 4.6 months (95% CI, 2.8%-7.2%). Median overall survival was 17.7 months (95% CI, 7.6%-not estimable). Grades 3-4 treatment-related adverse events occurred in 6 (23%) participants. CONCLUSIONS: The combination of MEDI0457 and durvalumab demonstrated acceptable safety and tolerability in patients with advanced HPV-16/18 cancers. The low ORR among patients with cervical cancer led to study discontinuation despite a clinically meaningful disease control rate.

BACKGROUND: The optimal treatment of recurrent ovarian granulosa cell tumors is not known. Preclinical studies and small case series have suggested direct antitumor activity of gonadotropin-releasing hormone agonists in the treatment of this disease, but little is known about the efficacy and safety of this approach. OBJECTIVE: This study aimed to describe patterns of use and clinical outcomes of leuprolide acetate in a cohort of patients with recurrent granulosa cell tumors. STUDY DESIGN: This was a retrospective cohort study of patients enrolled in the Rare Gynecologic Malignancy Registry at a large cancer referral center and affiliated county hospital. Patients meeting inclusion criteria had a diagnosis of recurrent granulosa cell tumor and received either leuprolide acetate or traditional chemotherapy as cancer treatment. Outcomes were separately examined for leuprolide acetate used as adjuvant treatment, maintenance therapy, and the treatment of gross disease. Demographic and clinical data were summarized using descriptive statistics. Progression-free survival was calculated from the initiation of treatment to the date of disease progression or death, and compared between groups with the log-rank test. The 6-month clinical benefit rate was defined as the percentage of patients without disease progression 6 months after starting therapy. RESULTS: Sixty-two patients received a total of 78 leuprolide acetate-containing therapy courses, owing to 16 instances of retreatment. Of these 78 courses, 57 (73%) were for treatment of gross disease, 10 (13%) were adjuvant to tumor reductive surgery, and 11 (14%) were for maintenance therapy. Patients had received a median of 2 (interquartile range, 1-3) systemic therapy regimens before their first leuprolide acetate treatment. Tumor reductive surgery (100% [62/62]) and platinum-based chemotherapy (81% [50/62]) were common before first leuprolide acetate exposure. The median duration of leuprolide acetate therapy was 9.6 months (interquartile range, 4.8-16.5). Nearly half of the therapy courses were single-agent leuprolide acetate (49% [38/78]). Combination regimens most often included an aromatase inhibitor (23% [18/78]). Disease progression was the most common cause of discontinuation (77% [60/78]); only 1 patient (1%) discontinued leuprolide acetate because of adverse events. In the treatment of gross disease, the 6-month clinical benefit rate for first use of leuprolide acetate was 66% (95% confidence interval, 54-82). Median progression-free survival was not statistically different compared with that which followed chemotherapy (10.3 months [95% confidence interval, 8.0-16.0] vs 8.0 months [95% confidence interval, 5.0-15.3]; P=.3). CONCLUSION: In a large cohort of patients with recurrent granulosa cell tumors, the 6-month clinical benefit rate of first-time leuprolide acetate treatment of gross disease was 66% and progression-free survival was comparable to patients treated with chemotherapy. Leuprolide acetate regimens were heterogeneous, but significant toxicity was rare. These results support leuprolide acetate as safe and effective for the treatment of relapsed adult granulosa cell tumors in the second line and beyond.

INTRODUCTION: Neuroendocrine carcinoma of the cervix (NECC) is an aggressive disease with high rates of nodal disease spread even in seemingly cervix-confined disease. Many providers routinely prescribe postoperative radiation therapy in an effort to reduce recurrences despite a lack of supporting studies. The objective of this study was to determine recurrence and mortality in patients with early-stage NECC who had pelvic radiation after radical hysterectomy compared to those who did not receive radiation. METHODS: We performed a meta-analysis of 13 unique studies that reported recurrence and/or mortality for patients with early-stage NECC who underwent radical hysterectomy with or without adjuvant radiation therapy. RESULTS: In 5 studies that reported overall recurrence rates, 63 (52.5%) of 120 patients who received postoperative radiation recurred compared to 70 (37.8%) of 185 patients who did not (RR 1.21, 95% CI: 0.85-1.70, p = 0.29). In 5 studies that reported pelvic recurrence rates, there were 15 pelvic recurrences (12.5%) in the 120 patients who received postoperative radiation compared to 45 pelvic recurrences (24.3%) in the 185 patients who did not (RR 0.60, 95% CI: 0.34-1.08, p = 0.09). In 13 studies that reported mortality rate, there were 138 deaths (34.8%) in 396 patients who received postoperative radiation therapy compared to 223 (35.2%) in 632 patients who did not (RR 1.08, 95% CI: 0.75-1.56, p = 0.66). CONCLUSIONS: The addition of routine postoperative radiation therapy in all patients with early-stage NECC after radical hysterectomy may reduce pelvic recurrences but does not appear to decrease overall recurrence or death. However, there may still be a role for postoperative radiation therapy in patients with additional high-risk pathologic factors.
