RESUMO
OBJECTIVE: To describe the long-term outcomes of patients with stage IVA cervical cancer, a rare and deadly disease for which long-term toxicity data are scarce, to guide clinician counseling and survivorship support. METHODS: In a retrospective review of a prospectively maintained database, we identified 76 patients with stage IVA cervical cancer with biopsy- or MRI-proven bladder mucosal involvement who received definitive radiotherapy (external beam radiotherapy [EBRT] alone or EBRT plus brachytherapy) with or without chemotherapy at our institution between 2000 and 2020. We used Kaplan-Meier modeling to estimate recurrence-free survival (RFS) and overall survival (OS) and used proportional hazard modeling to identify clinical variables associated with recurrence or survival. We performed actuarial competing risk modeling for severe late toxicity (grades 3 to 5, occurring >6 months of follow-up) and vesicovaginal fistulae (VVF), censoring for pelvic recurrence and death, and made comparisons between potential predictors using Gray's test and binary logistic regression. RESULTS: The median follow-up time was 76 months (interquartile range 58-91). The median OS duration was 35 months (range, 18-not reached), and the 2- and 5-year OS rates were 53.6% and 40.9%, respectively. OS and RFS did not differ significantly between patients who received EBRT alone (N = 18) or EBRT plus brachytherapy (N = 49). Current smoking was a strong predictor of severe late toxicity, whose incidence was 14% at 2 years and 17% at 10 years. The VVF incidence was 24% at 2 years and 32% at 10 years. CONCLUSION: Patients with stage IVA cervical cancer, even those who receive EBRT alone, can have long-term survival. These patients should be followed closely for late radiation-related toxicity.

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.

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 compare clinical and pathologic characteristics of women with surgical stage I endometrial carcinoma by location of first recurrence and describe characteristics of isolated vaginal recurrence. METHODS: Patients with 2009 International Federation of Obstetrics and Gynecology (FIGO) stage I endometrial carcinoma treated at two large cancer centers from 1/1/2009-12/31/2017 were identified. Sarcoma histology was excluded. Recurrences were grouped into isolated vaginal or extravaginal. Isolated vaginal recurrences were localized by anatomic location within the vaginal vault. Clinical and pathologic variables were compared with chi-square analysis, and Kaplan-Meier curves with log-rank tests. RESULTS: Of 2815 women identified, 278 (10%) experienced a recurrence. Sixty-one patients (2%) had an isolated vaginal recurrence, including 42 (69%) at the vaginal apex; 217 (8%) had an extravaginal recurrence, including 18 with a vaginal component. Median time to recurrence was 11 months (range, 1-68) for isolated vaginal recurrence and 20 months (range, 1-98) for extravaginal recurrence (P < .004). Of 960 patients (34%) treated with adjuvant vaginal brachytherapy (VBT), 156 (16%) recurred; 19 (2%) had an isolated vaginal recurrence, including 16 (84%) at the vaginal apex. Three-year PFS rates for isolated vaginal recurrence were 97.6% (SE ± 0.4%) with minimally invasive surgery (MIS) versus 96.9% (SE ± 1.1%) with open (P = .8), and for extravaginal recurrence were 91.8% (SE ± 0.7%) with MIS versus 90.8% (SE ± 1.8%) with open (P = .8). CONCLUSIONS: Isolated vaginal recurrences in stage I endometrial cancer are detected earlier than non-vaginal recurrences. Surgical approach does not appear to impact recurrence. Adjuvant VBT after primary surgery carries a 1%-2% risk of isolated vaginal apex recurrence.

BACKGROUND: Recurrent high-grade neuroendocrine cervical cancer has a very poor prognosis and limited active treatment options. OBJECTIVE: This study aimed to evaluate the efficacy of the 3-drug regimen of topotecan, paclitaxel, and bevacizumab in women with recurrent high-grade neuroendocrine cervical cancer. STUDY DESIGN: This retrospective cohort study used data from the Neuroendocrine Cervical Tumor Registry (NeCTuR), which include data abstracted directly from medical records of women diagnosed with high-grade neuroendocrine carcinoma of the cervix from English- and Spanish-speaking countries. The study compared women with recurrent high-grade neuroendocrine cervical cancer who received the topotecan, paclitaxel, and bevacizumab regimen as first- or second-line therapy for recurrence and women with recurrent high-grade neuroendocrine cervical cancer who received chemotherapy but not the topotecan, paclitaxel, and bevacizumab regimen. Patients continued chemotherapy until disease progression or the development of unacceptable toxic effects. Progression-free survival from the start of therapy for recurrence to the next recurrence or death, overall survival from the first recurrence, and response rates were evaluated. RESULTS: The study included 62 patients who received the topotecan, paclitaxel, and bevacizumab regimen as first- or second-line therapy for recurrence and 56 patients who received chemotherapy but not the topotecan, paclitaxel, and bevacizumab regimen for recurrence. The median progression-free survival rates were 8.7 months in the topotecan, paclitaxel, and bevacizumab regimen group and 3.7 months in the non-topotecan, paclitaxel, and bevacizumab regimen group, with a hazard ratio for disease progression of 0.27 (95% confidence interval, 0.17-0.48; P<.0001). In the topotecan, paclitaxel, and bevacizumab regimen group, 15% of patients had stable disease, 39% of patients had a partial response, and 18% of patients had a complete response. Compared with patients in the non-topotecan, paclitaxel, and bevacizumab regimen group, significantly more patients in the topotecan, paclitaxel, and bevacizumab regimen group remained on treatment at 6 months (31% vs 67%, respectively; P=.0004) and 1 year (9% vs 24%, respectively; P=.02). The median overall survival rates were 16.8 months in the topotecan, paclitaxel, and bevacizumab regimen group and 14.0 months in the non-topotecan, paclitaxel, and bevacizumab regimen group, with a hazard ratio for death of 0.87 (95% confidence interval, 0.55-1.37). CONCLUSION: Combination therapy with topotecan, paclitaxel, and bevacizumab was an active regimen in women with recurrent high-grade neuroendocrine cervical cancer and improved progression-free survival while decreasing the hazard ratio for disease progression.

Answer questions and earn CME/CNE Sexual concerns are prevalent in women with cancer or cancer history and are a factor in patient decision making about cancer treatment and risk-reduction options. Physical examination of the female cancer patient with sexual concerns, regardless of the type or site of her cancer, is an essential and early component of a comprehensive evaluation and effective treatment plan. Specialized practices are emerging that focus specifically on evaluation and treatment of women with cancer and sexual function problems. As part of a specialized evaluation, oncologists and their patients should expect a thorough physical examination to identify or rule out physical causes of sexual problems or dysfunction. This review provides oncology professionals with a description of the physical examination of the female cancer patient with sexual function concerns. This description aims to inform anticipatory guidance for the patient and to assist in interpreting specialists' findings and recommendations. In centers or regions where specialized care is not yet available, this review can also be used by oncology practices to educate and support health care providers interested in expanding their practices to treat women with cancer and sexual function concerns.

OBJECTIVE: The objective of this systematic review was to assess the oncologic outcomes of patients with International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IVB cervical cancer receiving definitive pelvic radiotherapy compared with systemic chemotherapy (with or without palliative pelvic radiotherapy). METHODS: This study was registered in PROSPERO (registration number CRD42022333433). A systematic literature review was conducted following the MOOSE checklist. MEDLINE (through Ovid), Embase, and Cochrane Central Register of Controlled Trials were searched from inception until August 2022. The inclusion criteria were patients with metastatic FIGO 2018 stage IVB cervical cancer, a histologic subtype of squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma that received definitive pelvic radiotherapy (≥45 Gy) as part of management compared with systemic chemotherapy with or without palliative (30 Gy) pelvic radiotherapy. Randomized controlled trials and observational studies with two arms of comparison were considered. RESULTS: The search identified 4653 articles; 26 studies were considered potentially eligible after removing duplicates, and 8 met the selection criteria. In total, 2424 patients were included. There were 1357 and 1067 patients in the definitive radiotherapy and chemotherapy groups, respectively. All included studies were retrospective cohort studies, and two were database population studies. The median overall survival reported in seven studies for the definitive radiotherapy arm versus systemic chemotherapy groups were 63.7 months versus 18.4 months (p<0.01), 14 months versus 16 months (p value not reported), 17.6 months versus 10.6 months (p<0.01), 32 months versus 24 months (p<0.01), 17.3 months versus 10 months (p<0.01), and 41.6 months versus 17.6 months (p<0.01), and not reached versus 19 months (p=0.13) respectively, favoring the groups that received definitive pelvic radiotherapy. The high clinical heterogeneity precluded the performance of meta-analysis, and all studies were at serious risk of bias. CONCLUSIONS: Definitive pelvic radiotherapy as part of treatment in patients with stage IVB cervical cancer may improve oncologic outcomes compared with systemic chemotherapy (with or without palliative radiotherapy); however, this is based on low-quality data. Prospective evaluation would be ideal before the adoption of this intervention in standard clinical practice.

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.

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.

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
PURPOSE: Two-dimensional radiotherapy is often used to treat cervical cancer in low- and middle-income countries, but treatment planning can be challenging and time-consuming. Neural networks offer the potential to greatly decrease planning time through automation, but the impact of the wide range of hyperparameters to be set during training on model accuracy has not been exhaustively investigated. In the current study, we evaluated the effect of several convolutional neural network architectures and hyperparameters on 2D radiotherapy treatment field delineation. METHODS: Six commonly used deep learning architectures were trained to delineate four-field box apertures on digitally reconstructed radiographs for cervical cancer radiotherapy. A comprehensive search of optimal hyperparameters for all models was conducted by varying the initial learning rate, image normalization methods, and (when appropriate) convolutional kernel size, the number of learnable parameters via network depth and the number of feature maps per convolution, and nonlinear activation functions. This yielded over 1700 unique models, which were all trained until performance converged and then tested on a separate dataset. RESULTS: Of all hyperparameters, the choice of initial learning rate was most consistently significant for improved performance on the test set, with all top-performing models using learning rates of 0.0001. The optimal image normalization was not consistent across architectures. High overlap (mean Dice similarity coefficient = 0.98) and surface distance agreement (mean surface distance < 2 mm) were achieved between the treatment field apertures for all architectures using the identified best hyperparameters. Overlap Dice similarity coefficient (DSC) and distance metrics (mean surface distance and Hausdorff distance) indicated that DeepLabv3+ and D-LinkNet architectures were least sensitive to initial hyperparameter selection. CONCLUSION: DeepLabv3+ and D-LinkNet are most robust to initial hyperparameter selection. Learning rate, nonlinear activation function, and kernel size are also important hyperparameters for improving performance.

BACKGROUND: Gut microbiome community composition differs between cervical cancer (CC) patients and healthy controls, and increased gut diversity is associated with improved outcomes after treatment. We proposed that functions of specific microbial species adjoining the mucus layer may directly impact the biology of CC. METHOD: Metagenomes of rectal swabs in 41 CC patients were examined by whole-genome shotgun sequencing to link taxonomic structures, molecular functions, and metabolic pathway to patient's clinical characteristics. RESULTS: Significant association of molecular functions encoded by the metagenomes was found with initial tumor size and stage. Profiling of the molecular function abundances and their distributions identified 2 microbial communities co-existing in each metagenome but having distinct metabolism and taxonomic structures. Community A (Clostridia and Proteobacteria predominant) was characterized by high activity of pathways involved in stress response, mucus glycan degradation and utilization of degradation byproducts. This community was prevalent in patients with larger, advanced stage tumors. Conversely, community B (Bacteroidia predominant) was characterized by fast growth, active oxidative phosphorylation, and production of vitamins. This community was prevalent in patients with smaller, early-stage tumors. CONCLUSIONS: In this study, enrichment of mucus degrading microbial communities in rectal metagenomes of CC patients was associated with larger, more advanced stage tumors.

OBJECTIVE: To evaluate the survival impact of adding definitive pelvic radiation therapy (RT) to chemotherapy among patients with stage IVB neuroendocrine cervical carcinoma (NECC). METHODS: We retrospectively studied patients with FIGO 2018 stage IVB NECC diagnosed during 1998-2020 who received chemotherapy with or without definitive whole pelvic RT (concurrent or sequential). Demographic, oncologic, and treatment characteristics were summarized. Progression-free (PFS) and overall survival (OS) were plotted using the Kaplan-Meier method, and hazard ratios (HRs) were calculated using Cox regression. RESULTS: The study included 71 patients. Median age was 43 years (range, 24-75). Fifty-nine patients (83%) had pure neuroendocrine histology, and 57 (80%) had pretreatment tumor size >4 cm. Fifty-six patients (79%) received chemotherapy alone with (n = 15) or without (n = 41) palliative pelvic RT, and 15 (21%) received chemotherapy and definitive pelvic RT (chemo+RT). Median follow-up time was 20.1 months (range, 11.3-170.3) for the chemo+RT group and 13.5 months (range, 0.9-73.6) for the chemotherapy-alone group. Median PFS was 10.3 months (95% CI, 7.5-∞) for the chemo+RT group vs 6.6 months (95% CI, 6.1-8.7) for the chemotherapy-alone group (p = 0.0097). At 24 months, the PFS rate was 24% for chemo+RT vs 7.8% for chemotherapy alone. Median OS was 20.3 months (95% CI, 18.5-∞) for the chemo+RT group vs 13.6 months (95% CI, 11.3-19.2) for the chemotherapy-alone group (p = 0.0013). At 24 months, the OS rate was 49.2% for chemo+RT vs 21.5% for chemotherapy alone. In a Cox regression model, definitive RT was associated with improved PFS (HR, 0.44; 95% CI, 0.23-0.83; p = 0.0119) and OS (HR, 0.31; 95% CI, 0.14-0.65; p = 0.0022). CONCLUSIONS: Addition of definitive pelvic RT to chemotherapy may improve survival in patients with stage IVB NECC.

OBJECTIVE: Radiation therapy (RT) may improve outcomes for patients with oligometastatic cancer. We sought to determine if there are long-term survivors treated with definitive RT for recurrent or oligometastatic gynecological cancer (ROMGC), and to evaluate the clinical and disease characteristics of these patients. METHODS: We performed a landmark analysis in 48 patients with ROMGC who survived for ≥5 years following definitive RT of their metastasis. Patient characteristics were extracted from the medical record. DFS was modeled using the Kaplan-Meier method. RESULTS: This cohort included 20 patients (42%) with ovarian cancer, 16 (33%) with endometrial cancer, 11 (23%) with cervical cancer, and one (2%) with vaginal cancer. The sites of ROMGC were the pelvic (46%), para-aortic (44%), supraclavicular (7%), mediastinal (4%), axillary (4%) lymph nodes and the lung (5.5%). Median total RT dose and fractionation were 62.1 Gy and 2.1 Gy/fraction; one patient was treated with SBRT. 32 patients (67%) received chemoradiation; these patients had higher rates of median DFS than those treated with RT alone (93 vs. 34 months, P = 0.05). At median follow-up of 11.7 years, 11 (23%) patients had progression of disease. 20 (42%) patients had died, 9 (19%) died from non-gynecologic cancer and 8 (17%) from gynecologic cancer (three were unknown). 25 (52%) patients were alive and disease-free (10 initially had endometrial cancer [63% of these patients], eight had cervical cancer [73%], six had ovarian cancer [30%], one had vaginal cancer [100%]). CONCLUSIONS: Long-term survival is possible for patients treated with definitive RT for ROMG, however randomized data are needed to identify which patients derive the most benefit.

OBJECTIVE: Uterine serous carcinoma is a rare but aggressive subtype of endometrial adenocarcinoma. Our objective was to compare adjuvant treatment strategies for patients with early stage uterine serous carcinoma. METHODS: This multi-institutional, retrospective cohort study evaluated patients with early stage uterine serous carcinoma. Patients with FIGO Stage IA-II disease after surgery, whose tumors had serous or any mixed serous/non-serous histology were included. Patients with carcinosarcoma were excluded. Clinical data were abstracted from local medical records. Summary statistics, Fisher's exact, and Kruskal-Wallis tests were used to analyze demographic and clinical characteristics. Univariable and multivariable analyses were performed for recurrence-free and overall survival. RESULTS: There were 737 patients included. Most patients had Stage IA disease (75%), 49% of which had no myometrial invasion. Only 164 (24%) tumors had lymphatic/vascular space invasion. Adjuvant treatment varied: 22% received no adjuvant therapy, 17% had chemotherapy alone, 19% had cuff brachytherapy, 35% had cuff brachytherapy with chemotherapy, and 6% underwent pelvic radiation. Adjuvant treatment was significantly associated with a decreased risk of recurrence (p = 0.04). Compared with no adjuvant therapy, patients who received brachytherapy or brachytherapy/chemotherapy had improved recurrence-free survival (HR 0.59, 95% CI 0.40-0.86; HR 0.65, 95% CI 0.49-0.88, respectively) and overall survival (HR 0.53, 95% CI 0.35-0.79; HR 0.49, 95% CI 0.35-0.69, respectively). Improved survival with brachytherapy and brachytherapy/chemotherapy persisted on multivariable analyses. Chemotherapy alone was also associated with improved overall survival compared with no adjuvant treatment (HR 0.55, 95% CI 0.37-0.81). CONCLUSIONS: Adjuvant therapy was associated with a decreased risk of recurrence relative to observation alone. Adjuvant cuff brachytherapy with and without chemotherapy was associated with improved survival outcomes in patients with early stage uterine serous carcinoma.

BACKGROUND: Gynecologic tract melanoma (GTM) is a rare malignancy with historically poor outcomes. The current study examines patterns of care and oncologic outcomes in a large single-institution cohort from the contemporary therapeutic era. METHODS: Patterns of care and predictors of outcomes were evaluated for all GTM patients without metastatic disease at diagnosis who were treated at our institution between 2009 and 2020 with >6 months of follow-up. RESULTS: Of the 124 patients included, anatomic subsites were vulvar (n = 82, 66%), vaginal (n = 34, 27%), or cervical (n = 8, 6%). Primary tumor was resected for 85% (n = 106) with surgical nodal evaluation for 60% (n = 75). Systemic therapy, most commonly immune checkpoint inhibitors (ICI, 58% systemic therapy), was used to treat all except one unresectable patient (17/18) and 33% (35/106) of resectable patients. Seven patients received neoadjuvant ICI. Fourteen patients received adjuvant radiation therapy to the pelvis (RT, 13% of those undergoing resection). With a median follow-up of 45 months, 100 patients (81%) recurred. Four-year actuarial outcomes were: 46% local control, 53% nodal control, 36% distant metastasis-free survival, 17% disease-free survival, 49% melanoma-specific survival and 48% overall survival. Mitotic rate > 10/mm2, nodal involvement and non-vulvar anatomic subsite were associated with poor outcomes. Patients treated after 2016 did not have significantly better outcomes than those treated earlier. CONCLUSIONS: Patients with GTM continue to have poor outcomes in the contemporary therapeutic era with particularly notable poor local disease control relative to other mucosal melanoma subtypes. More effective oncologic therapy is needed.

OBJECTIVE: To optimize the use of confirmatory endoscopic exams (cystoscopy/proctoscopy) in the staging of locally advanced cervical cancer (LACC), the present study evaluates the predictive value of radiological exams (CT and MRI) to detect bladder/rectum invasion. METHODS: A systematic search of databases (PubMed and EMBASE) was performed (CRD42021270329). The inclusion criteria were: a) cervix cancer diagnosis; b) staging CT and/or MRI (index test); c) staging cystoscopy and/or proctoscopy (standard test); and d) numbers of true positives (TP), true negatives (TN), false positives (FP), and false negatives (FN) provided. A random-effects bivariate meta-analysis of positive predictive value (PPV) and negative predictive value (NPV) was performed with moderator analyses by imaging modality (CT and MRI) and prevalence. RESULTS: Nineteen studies met the inclusion criteria, totaling 3480 and 1641 patients for bladder and rectum analyses, respectively. For bladder invasion (prevalence ranged from 0.9% to 34.5%), the overall PPV was 45% (95% confidence interval, 33%-57%, based on 19 studies). Per subgroup, the PPV was 31% for MRI/prevalence ≤6%, 33% for CT/prevalence ≤6%, and 69% for CT/prevalence >6%. For rectal invasion (prevalence ranged from 0.4% to 20.0%), the overall PPV was 30% (95% confidence interval, 17%-47%, based on 8 studies). Per subgroup, the PPV was 36% for MRI/prevalence ≤1%, 17% for MRI/prevalence >1%, and 38% for CT/prevalence >1%. The overall NPV for bladder invasion and rectal invasion were 98% (95% confidence interval, 97%-99%) and 100% (95% confidence interval, 99%-100%), respectively. Considering prevalence and radiological modality, the point estimate of NPV varied from 95% to 100% for bladder invasion and from 99% to 100% for rectum invasion. CONCLUSIONS: Due to low PPV (<50%) of radiological staging, endoscopic exams may be necessary to correctly assess radiological stage IVA LACC. However, they are not necessary after negative radiological exam (NPV ≥95%).

Vaginal cancer is a rare cancer. A lot of the data used in the treatment of this cancer are extrapolated from cervical cancer data. Radiation therapy plays a significant role in the treatment of vaginal cancer. The advances in radiation therapy in both external beam and brachytherapy have improved local control, survival, and toxicity. Brachytherapy plays an important role in treating vaginal cancer, but treatment should be individualized to each tumor. Imaging, particularly magnetic resonance imaging, plays an essential role in the management of patients with vaginal cancer, from diagnosis to staging to treatment management to surveillance.

OBJECTIVE: Pelvic floor dysfunction is a common adverse effect of uterine cancer treatment. In this study we compared patient-reported outcomes regarding pelvic floor dysfunction among uterine cancer survivors after hysterectomy and bilateral salpingo-oophorectomy, surgery and brachytherapy, or surgery and external beam radiotherapy with or without brachytherapy versus women who had a hysterectomy for benign indications. METHODS: We used the validated 20-item Pelvic Floor Distress Inventory to assess lower urinary distress, colorectal distress, and pelvic organ prolapse dysfunction in each treatment group. Pelvic floor dysfunction-related quality of life in these domains was compared across treatment modalities using the Pelvic Floor Impact Questionnaire-7. Treatment type, body mass index, comorbidities, and number of vaginal births were obtained from medical records. A zero-inflated negative binomial regression model was used to assess the association of treatment regimens and covariates relative to the non-cancer cohort. RESULTS: A total of 309 surveys were analyzed. The median age of the patients at surgery was 58 years (range 20-87) and the median age at survey completion was 66 years (range 34-92). Most participants reported experiencing at least one symptom of pelvic floor dysfunction (76% by Pelvic Floor Distress Inventory-2). The type of treatment had no effect on overall pelvic floor dysfunction on multivariate analysis (all p>0.05). Worse urinary-related symptoms were associated with higher body mass index at surgery (OR 1.41), higher age at time of survey (OR 1.07), and higher numbers of vaginal births (OR 1.43) (all p<0.05). CONCLUSIONS: Overall, pelvic floor dysfunction did not significantly vary by treatment modality. Our findings suggest complex interactions among age, body mass index, and parity as to how uterine cancer treatment affects pelvic floor quality of life, which should be considered in the choice of treatment strategy and patient counseling.
RESUMO
BACKGROUND: Uterine clear cell and serous carcinomas have a high propensity for locoregional and distant spread, tend to be more advanced at presentation, and carry a higher risk of recurrence and death than endometrioid cancers. Limited prospective data exist to guide evidence-based management of these rare malignancies. OBJECTIVE: The American Radium Society sought to summarize evidence-based guidelines developed by a multidisciplinary expert panel that help to guide the management of uterine clear cell and serous carcinomas. METHODS: The American Radium Society Appropriate Use Criteria presented in this manuscript were developed by a multidisciplinary expert panel using an extensive analysis of current published literature from peer-reviewed journals. A well-established methodology (modified Delphi) was used to rate the appropriate use of diagnostic and therapeutic procedures for the management of uterine clear cell and serous carcinomas. RESULTS: The primary treatment for non-metastatic uterine clear cell and serous carcinomas is complete surgical staging, with total hysterectomy, salpingo-oophorectomy, omentectomy, and lymph node staging. Even in early-stage disease, patients with uterine clear cell and serous carcinomas have a worse prognosis than those with type I endometrial cancers, warranting consideration for adjuvant therapy regardless of the stage. Given the aggressive nature of these malignancies, and until further research determines the most appropriate adjuvant therapy, it may be reasonable to counsel patients about combined-modality treatment with systemic chemotherapy and radiotherapy. CONCLUSION: Patients diagnosed with uterine clear cell and serous carcinomas should undergo complete surgical staging. Multimodal adjuvant therapies should be considered in the treatment of both early-stage and advanced-stage disease. Further prospective studies or multi-institutional retrospective studies are warranted to determine optimal sequencing of therapy and appropriate management of patients based on their unique risk factors. Long-term surveillance is indicated due to the high risk of locoregional and distant recurrence.
