RESUMEN
MYC amplifications have been frequently detected in radiation (RT)-associated angiosarcomas (ASs) by low-resolution molecular methods. However, large-scale next-generation sequencing (NGS) studies to investigate the genomic landscape of RT-AS are scarce, particularly compared with other RT-associated sarcomas. We performed a detailed comparative genomic investigation of RT-AS versus other RT-associated histotypes, as well as sporadic sarcomas with similar histologies. Our institutional targeted DNA-NGS assay database was searched for RT-associated sarcomas. Clinical outcome data, pathologic diagnosis, and the types and frequencies of genomic alterations, including single nucleotide variants (SNVs) and copy number alterations (CNAs), were analyzed. The cohort consisted of 82 patients, 68 (83%) females and 14 (17%) males, aged 37-88 (mean 64) years. Forty-four RT-ASs (38 from breast) and 38 RT sarcomas of other histologies, including 12 malignant peripheral nerve sheath tumors (RT-MPNSTs), 14 undifferentiated pleomorphic sarcomas (RT-UPSs), and 12 osteosarcomas (RT-OSs), were included. Median time intervals from radiation to initial diagnosis in RT-AS (8.0 years) were significantly lower than those in RT-MPNST and RT-UPS (12.5 and 18.5 years), respectively. Each RT-sarcoma histotype harbored distinct mutations and CNAs. RT-associated AS had more frequent MYC, FLT4, CRKL, HRAS, and KMT2D alterations than sporadic AS (enriched in TP53, KDR, ATM, ATRX), whereas the mutational landscapes of MPNST, UPS, and OS were similar in both RT and non-RT settings. CDKN2A/B deletions and TP53 alterations were infrequent in RT-AS compared with other RT sarcomas. Among RT sarcomas, RT-AS harbored the lowest fraction of genome altered (FGA), while RT-MPNST showed the highest FGA. RT-AS had the lowest insertion:SNV and deletion:SNV ratios, while RT-UPS had the highest. The predominant mutational signatures were associated with errors in DNA repair and replication. In conclusion, RT-AS has a distinct genomic landscape compared with other RT sarcomas and sporadic AS. Potential molecular targets for precision medicine may be histotype-dependent. © 2023 The Pathological Society of Great Britain and Ireland.

OBJECTIVE: We assessed the prognosis and molecular subtypes of early stage endometrioid endometrial cancer with isolated tumor cells within sentinel lymph nodes (SLNs) compared with node negative disease. METHODS: Patients diagnosed with stage IA, IB, or II endometrioid endometrial cancer and primary surgical management were identified from January 1, 2007 to December 31, 2019. All SLNs underwent ultrastaging according to the institutional protocol. Patients with cytokeratin positive cells, micrometastases, and macrometastases were excluded. Clinical, pathology, and molecular subtype data were reviewed. RESULTS: Overall, 1214 patients with early stage endometrioid endometrial cancer met the inclusion criteria, of whom 1089 (90%) had node negative disease and 125 (10%) had isolated tumor cells. Compared with node negative disease, the presence of isolated tumor cells had a greater association with deep myometrial invasion, lymphovascular space invasion, receipt of adjuvant therapy, and adjuvant chemotherapy with or without radiation (p<0.01). There was no significant difference in survival rates between patients with isolated tumor cells and node negative disease (3 year progression free survival rate 94% vs 91%, respectively, p=0.21; 3 year overall survival rate 98% vs 96%, respectively, p=0.45). Progression free survival did not significantly differ among patients with isolated tumor cells who received no adjuvant therapy or chemotherapy with or without radiation (p=0.31). There was no difference in the distribution of molecular subtypes between patients with isolated tumor cells (n=28) and node negative disease (n=194; p=0.26). Three year overall survival rates differed significantly when stratifying the entire cohort by molecular subtype (p=0.04). CONCLUSIONS: Patients with isolated tumor cells demonstrated less favorable uterine pathologic features and received more adjuvant treatment with similar survival compared with patients with nodenegative disease. Among the available data, molecular classification did not have a significant association with the presence of isolated tumor cells, although copy number-high status was a poor prognostic indicator in early stage endometrioid endometrial cancer.
RESUMEN
OBJECTIVES: To compare outcomes of patients with premalignant endometrial pathology undergoing hysterectomy with or without sentinel lymph node (SLN) removal. Outcomes of interest included surgical adverse events (AEs), cancer status on final pathology, postoperative treatment, and The Cancer Genome Atlas (TCGA) molecular risk profiles. METHODS: We retrospectively identified patients with premalignant pathology on preoperative endometrial biopsy who underwent hysterectomy with or without SLN mapping/excision at our institution from 01/01/2017-12/31/2021. Clinical, pathologic, surgical, and TCGA profiling data were abstracted. Appropriate statistical tests were used. RESULTS: Of 221 patients identified, 161 (73%) underwent hysterectomy with SLN excision and 60 (27%) underwent hysterectomy without SLN excision. Median age and body mass index were similar between groups. Median operative time was 130 min for those who underwent SLN mapping/excision versus 136 min for those who did not (p = 0.6). Thirty-day postoperative AE rates were 9% (n = 15/161) and 13% (n = 8/60), respectively (p = 0.9). Ninety-eight (44%) of 221 patients had grade 1-2 endometrioid endometrial cancer on final pathology (4 [4%] were stage IB or higher). Ten (10%) of 98 patients, all within the SLN group, received adjuvant treatment. Among all patients, of 33 (15%) with TCGA molecular classification data, 27 (82%) had copy number-low, 3 (9%) microsatellite instability-high, 2 (6%) POLE-ultramutated, and 1 (3%) copy number-high disease. CONCLUSIONS: SLN assessment appears safe, detects a small number of occult nodal metastases for those upstaged, and provides additional staging information that can guide adjuvant treatment. SLN mapping should be discussed in preoperative counseling and offered using a shared decision-making approach.

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.

PURPOSE: Using next generation sequencing (NGS), The Cancer Genome Atlas (TCGA) found that endometrial carcinomas (ECs) fall under one of four molecular subtypes, and a POLE mutation status, mismatch repair (MMR) and p53 immunohistochemistry (IHC)-based surrogate has been developed. We sought to retrospectively classify and characterize a large series of unselected ECs that were prospectively subjected to clinical sequencing by utilizing clinical molecular and IHC data. EXPERIMENTAL DESIGN: All patients with EC with clinical tumor-normal MSK-IMPACT NGS from 2014 to 2020 (n = 2115) were classified by integrating molecular data (i.e., POLE mutation, TP53 mutation, MSIsensor score) and MMR and p53 IHC results. Survival analysis was performed for primary EC patients with upfront surgery at our institution. RESULTS: Utilizing our integrated approach, significantly more ECs were molecularly classified (1834/2115, 87%) as compared to the surrogate (1387/2115, 66%, p < 0.001), with an almost perfect agreement for classifiable cases (Kappa 0.962, 95% CI 0.949-0.975). Discrepancies were primarily due to TP53 mutations in p53-IHC-normal ECs. Of the 1834 ECs, most were of copy number (CN)-high molecular subtype (40%), followed by CN-low (32%), MSI-high (23%) and POLE (5%). Histologic and genomic variability was present amongst all molecular subtypes. Molecular classification was prognostic in early- and advanced-stage disease, including early-stage endometrioid EC. CONCLUSIONS: The integration of clinical NGS and IHC data allows for an algorithmic approach to molecularly classifying newly diagnosed EC, while overcoming issues of IHC-based genetic alteration detection. Such integrated approach will be important moving forward given the prognostic and potentially predictive information afforded by this classification.

OBJECTIVE: To assess survival among patients diagnosed with uterine carcinosarcoma (CS) who underwent sentinel lymph node (SLN) biopsy alone vs. systematic lymph node dissection (LND). METHODS: We identified newly diagnosed CS patients who underwent primary surgical management from January 1996-December 2019. The SLN cohort underwent SLN biopsy alone with bilateral SLNs identified. The systematic LND cohort did not undergo SLN biopsy. RESULTS: Ninety-nine patients underwent SLN biopsy, and 100 patients underwent systematic LND. There was no difference by age, stage, body mass index, myoinvasion (<50%, ≥50%), lymphovascular space invasion, or positive washings. Eighty-five SLN (85.9%) and 15 LND (15%) underwent minimally invasive surgery (P < 0.001). The median total node count was four (range, 1-13) for SLN and 19 (range, 2-50) for LND (P < 0.001). Nodal metastasis occurred in 23 (23.2%) SLN and in 22 (22%) LND (P = 0.4). Postoperative therapy was administered to 85 (85.9%) SLN and 71 (71%) LND (P = 0.02). Median follow-up was 33 months (range, 1-205) for SLN and 55.3 months (range, 1-269) for LND (P = 0.001). The three-year progression-free survival (PFS) was 62.9% (SE 5.2%) for SLN and 52.3% (SE 5.3%) for LND (P = 0.13). The three-year overall survival (OS) was 72.1% (SE 5.1%) for SLN and 71.6% (SE 4.6%) for LND (P = 0.68). An isolated nodal recurrence occurred in two (2%) SLN and four (4%) LND (P = 0.26). CONCLUSIONS: There is no difference in PFS or OS among CS patients who undergo SLN biopsy vs. systematic LND. SLN biopsy detects nodal metastasis without compromising oncologic outcomes.

OBJECTIVES: Gastric-type endocervical adenocarcinoma (GEA) is a rare form of cervical cancer not associated with human papilloma virus (HPV) infection. We summarize our experience with GEA at a large cancer center. METHODS: Clinical and demographic information on all patients diagnosed with GEA between June 1, 2002 and July 1, 2019 was obtained retrospectively from clinical charts. Kaplan-Meier survival analysis was performed to describe progression-free survival (PFS) and overall survival (OS). Tumors from a subset of patients underwent next generation sequencing (NGS) analysis. RESULTS: A total of 70 women with GEA were identified, including 43 who received initial treatment at our institution: of these 4 (9%) underwent surgery alone, 15 (35%) underwent surgery followed by adjuvant therapy, 10 (23%) were treated with definitive concurrent chemoradiation (CCRT), 7 (16%) with chemotherapy alone, and 3 (7%) with neoadjuvant CCRT and hysterectomy with or without chemotherapy. One-third (n = 14) of patients experienced disease progression, of whom 86% (n = 12) had prior CCRT. The median PFS and OS for patients with stage I GEA were 107 months (95% CI 14.8-199.2 months) and 111 months (95% CI 17-205.1 months) respectively, compared to 17 months (95% CI 5.6-28.4 months) and 33 months (95% CI 28.2-37.8 months) for patients with stages II-IV, respectively. On NGS, 4 patients (14%) had ERBB2 alterations, including 2 patients who received trastuzumab. CONCLUSIONS: GEA is an aggressive form of cervical cancer with poor PFS and OS when diagnosed at stage II or later. Further investigation is needed to identify the optimal management approach for this rare subtype.

OBJECTIVE: To assess potential predictive variables for nodal metastasis and survival outcomes in patients with newly diagnosed, low-grade endometrial stromal sarcoma. METHODS: We performed a single-institution, retrospective analysis of consecutive patients with newly diagnosed, low-grade endometrial stromal sarcoma who presented between January 1, 1980 and December 31, 2019 and underwent hysterectomy at our institution or presented within 3 months of primary surgery elsewhere before recurrence. Patients who presented to our institution only at recurrence were excluded. Patients with <3 months of follow-up were excluded from survival analyses. RESULTS: We identified 127 consecutive patients for analysis. Median age at diagnosis was 48 years (range 19-88 years); 91 (74.6%) of 127 were pre-menopausal; and 74 (58.3%) of 127 had uterine-confined, stage I tumors. Of 56 patients (44.1%) who underwent lymph node sampling, 10 (17.9%) had nodal metastasis. Of the 10 with nodal metastasis, 1 (10%) did not have lymphadenopathy or extra-uterine disease, 4 (40%) had lymphadenopathy only, 1 (10%) had extra-uterine disease only, and 4 (40%) had both. Among the 29 patients without apparent extra-uterine disease or gross lymphadenopathy, there was one occult lymph node metastasis (3.4%). Gross lymphadenopathy at time of surgery was predictive for lymph node metastasis (p<0.001). Median follow-up was 69 months (range 4-336) for the 95 patients included in the survival analyses. The 5-year progression-free survival and disease-specific survival rates were 79.8% and 90.8%, respectively. Patients with stage I tumors had longer progression-free survival than those with stage II-IV disease (p<0.001); there was no difference in disease-specific survival (p=0.63). Post-operative observation versus adjuvant therapy with hormone blockade or radiation therapy did not result in progression-free survival differences for stage I or completely resected stage II-IV disease (p=0.50 and p=0.81, respectively). Similarly, there was no disease-specific survival difference for completely resected stage II-IV disease (p=0.3). CONCLUSIONS: Lymph node dissection in patients with low-grade endometrial stromal sarcoma should be reserved for those with clinically suspicious lymphadenopathy. Disease stage correlated with progression-free survival but not disease-specific survival. Post-operative therapy did not improve progression-free survival or disease-specific survival.

BACKGROUND: We previously reported that the cumulative risk of femoral fracture in patients treated with intensity-modulated radiation therapy (IMRT) for thigh and groin soft tissue sarcoma (STS) is low. In the current study, we sought to evaluate the effect of radiation dose constraints on the rate of femoral fracture in a more contemporary cohort. METHODS: All patients treated with IMRT for STS of the thigh or groin from 2004 to 2016 were included (n = 145). Beginning in 2011, radiation dose was constrained to a mean dose of < 37 Gy, volume of bone receiving ≥ 40 Gy (V40Gy) < 64%, and maximum dose < 59 Gy to limit the dose to the femur. RESULTS: Sixty-one patients were treated before dose constraints were implemented, and 84 patients were treated after. Median follow-up for patients treated before and after constraints were implemented was 6.1 and 5.7 years, respectively, and the two groups were demographically and clinically similar. On univariate analysis, the 5-year cumulative incidence of femoral fracture among patients treated with and without dose constraints was 1.8% (95% confidence interval [CI] 0.3-12.2%) versus 7.4% (95% CI 3.1-17.6%) [p = 0.11, p = non-significant, respectively]. On multivariable analysis, only age ≥ 60 years was significantly associated with increased risk of fracture. CONCLUSIONS: The risk of femoral fracture after IMRT for STS of the thigh/groin is low, and with the implementation of radiation dose constraints, the risk is < 2%. Although longer follow-up is needed, our results support the utilization of extremity sarcoma IMRT-specific dose constraints for fracture prevention.

OBJECTIVE: Gaps in access to appropriate cancer care, and associated cancer mortality, have widened across socioeconomic groups. We examined whether demographic and socioeconomic factors influenced receipt of adjuvant radiation therapy (RT) in patients with high-risk, early-stage endometrial cancer. METHODS: A retrospective study cohort was selected from 349,404 endometrial carcinoma patients from the National Cancer Database in whom adjuvant RT would be recommended per national guidelines. The study included surgically treated patients with endometrioid endometrial cancer with one of the following criteria: 1) FIGO 2009 stage IB, grade 1/2 disease, age ≥ 60 years; 2) stage IB, grade 3 disease; or 3) stage II disease. Logistic regression analysis was performed to identify factors associated with omission of adjuvant RT. Association between adjuvant RT, covariables, and overall survival (OS) was assessed with multivariable Cox proportional hazards models. RESULTS: 19,594 patients were eligible for analysis; 47% did not receive adjuvant RT. Omission of adjuvant RT was more prevalent among African-American, Hispanic, and Asian compared to non-Hispanic white patients (OR 0.79, 95%CI: 0.69-0.91; OR 0.75, 95%CI: 0.64-0.87; OR 0.75, 95%CI: 0.60-0.94, respectively). Lower median household income of patient's area of residence, lack of health insurance, treatment at non-academic hospitals, farther distance to treatment facilities, and residence in metropolitan counties were associated with omission of adjuvant RT. Such omission was independently associated with worse OS (HR1.43, p < 0.001). CONCLUSION: Adjuvant RT is omitted in 47% of patients with early-stage, high-risk endometrial cancer, which is associated with poor access to appropriate, high-quality care and worse outcome.

OBJECTIVE: To examine the role of non-exenterative secondary cytoreductive surgery (SCS) compared with non-surgical treatments and identify predictors of improved survival for patients with recurrent endometrial cancer (EC). METHODS: All patients undergoing primary surgical management for EC 1/1/2009-12/31/2017 who subsequently developed recurrence were retrospectively identified. Survival was determined from date of diagnosis of first recurrence to last follow-up and estimated using Kaplan-Meier method. Differences in survival were analyzed using Log-rank and Wald tests, based on Cox Proportional Hazards model. RESULTS: Among 376 patients with recurrent EC, median time to recurrence was 14.3 months (range, 0.2-102.2), post-recurrence median survival 29 months, median follow-up 29.2 months (range, 0-116). Sixty-one patients (16.2%) received SCS, 257 (68.4%) medical management (MM) (chemotherapy and/or radiation therapy), 32 (8.5%) hormonal therapy, 26 (6.9%) no further therapy. Patients selected for SCS were younger, had more endometrioid histology, more stage I disease at initial diagnosis, no residual disease after primary surgery, longer interval to first recurrence or progression, and the longest OS (57.6 months) (95% CI, 33.3-not reached). On multivariate analysis SCS was an independent predictor of improved survival. Among the 61 SCS patients, age < 70 at time of initial diagnosis, and endometrioid histology, were associated with improved post-relapse survival univariately (p = 0.008, 0.03, respectively). CONCLUSIONS: While MM was the most common treatment for first recurrence of EC, patients selected for surgery demonstrated the greatest survival benefit even after controlling for tumor size, site, histology, stage, time to recurrence. Careful patient selection and favorable tumor factors likely play a major role in improved outcomes. Surgical management should be considered whenever feasible in medically eligible patients, with additional consideration given to our suggested criteria.

PURPOSE: To assess the feasibility and efficacy of a non-hormonal hyaluronic acid (HLA) vaginal gel in improving vulvovaginal estrogen-deprivation symptoms in postmenopausal women with a history of hormone receptor-positive (HR+) cancer. METHODS: For this single-arm, prospective longitudinal trial, we identified disease-free patients with a history of HR+ breast cancer treated with aromatase inhibitors or HR+ endometrial cancer treated with surgery and postoperative radiation. Participants used HLA daily for the first 2 weeks, and then 3×/week until weeks 12-14; dosage was then increased to 5×/week for non-responders. Vulvovaginal symptoms and pH were assessed at 4 time points (baseline [T1], 4-6 weeks [T2], 12-14 weeks [T3], 22-24 weeks [T4]) with clinical evaluation, the Vaginal Assessment Scale (VAS), Vulvar Assessment Scale (VuAS), Female Sexual Function Index (FSFI), and Menopausal Symptom Checklist (MSCL). RESULTS: Of 101 patients, mean age was 55 years (range, 31-78), 68% (n = 69) were partnered, and 60% (n = 61) were sexually active. In linear mixed models, VAS/VuAS scores significantly improved at all assessment points (all p < 0.001). MSCL scores similarly improved (all p < 0.001). FSFI scores significantly improved from T1 to T2 (p < 0.03), T3 (p < 0.001), and T4 (p < 0.001). Severe vaginal pH (> 6.5) decreased from 26% at T1 to 19% at T4 (p = 0.18). CONCLUSIONS: HLA moisturization improved vulvovaginal health/sexual function of cancer survivors. While HLA administration 1-2×/week is recommended for women in natural menopause, a 3-5×/week schedule appears to be more effective for symptom relief in cancer survivors.

OBJECTIVE: We report the incidence of occult nodal metastasis in patients who underwent primary surgical staging for apparent early endometrioid or serous endometrial cancer with bilateral SLN mapping and enhanced pathology. Occult ovarian metastasis rates were also reported. METHODS: Patients with clinical stage I serous or endometrioid endometrial cancer who underwent primary staging surgery with successful bilateral SLN mapping from 1/2005-12/2018 were retrospectively evaluated. Rates of isolated tumor cells (ITCs), micro- and macrometastatic nodal disease, and occult ovarian involvement were reported. RESULTS: Of 1044 patients, 959 had endometrioid and 85 serous carcinoma. There were no positive SLNs among 510 patients with noninvasive FIGO grade 1/2 endometrioid carcinoma and < 1%ITCs. Grade 1: 4.5%(9/202) with inner-half and 10%(6/62) with outer-half myoinvasion had positive SLNs. Grade 2: rates were 4%(3/76) and 20%(8/41), respectively. Grade 3: 5%(1/20) with noninvasive, 3%(1/31) with inner-half, and 24%(4/17) with outer-half myoinvasion had positive SLNs. ITC incidence increased with depth of myoinvasion-25% of deeply invasive grade 1/2 and 18% of deeply invasive grade 3 tumors. Four (10%) of 41 patients with noninvasive serous endometrial carcinoma had ITCs or positive SLNs. There were no occult ovarian metastases with grades 1/2 disease, 2/68 (3%) with grade 3 disease, and 2/85 (2%) with serous endometrial carcinoma. CONCLUSION: Ultrastaging SLNs may be unwarranted in low-grade noninvasive endometrioid cancer but valuable in noninvasive serous carcinoma. Occult ovarian metastasis is uncommon in early endometrial carcinoma and occurs in 2-3% of high-risk histologies. Further research is needed to determine ITC significance, particularly with regard to adjuvant treatment.

OBJECTIVES: The objective of our study was to assess survival among patients with uterine serous carcinoma (USC) undergoing sentinel lymph node (SLN) mapping alone versus patients undergoing systematic lymphadenectomy (LND). METHODS: We retrospectively reviewed patients undergoing primary surgical treatment for newly diagnosed USC at our institution from 1/1/1996-12/31/2017. Patients were assigned to either SLN mapping alone (SLN cohort) or systematic LND without SLN mapping (LND cohort). Progression-free (PFS) and overall survival (OS) were estimated using Kaplan-Meier method, compared using Logrank test. RESULTS: 245 patients were available for analysis: 79 (32.2%) underwent SLN, 166 (67.7%) LND. 132 (79.5%) in the LND cohort had paraaortic LND (PALND) versus none in the SLN cohort. Median age: 66 and 68 years in the SLN and LND cohorts, respectively (p>0.05). Proportion of stage I/II disease: 67.1% (n = 53) and 64.5% (n = 107) in the SLN and LND cohorts, respectively (p>0.05). Median follow-up: 23 (range, 1-96) and 66 months (range, 4-265) in the SLN and LND cohorts, respectively (p < 0.001). Two-year OS in stage I/II disease (n = 160, 60.1%): 96.6% (SE ± 3.4) and 89.6% (SE ± 2.2) in the SLN and LND cohorts, respectively (p = 0.8). Two-year OS in stage III disease (n = 77): 73.6% (SE ± 10.2) and 77.3% (SE ± 5.8) in the SLN and LND cohorts, respectively (p = 0.8). CONCLUSIONS: SLN mapping alone and systematic LND yielded similar survival outcomes in stage I-III USC. In our practice, the SLN algorithm has replaced systematic LND as the primary staging modality in this setting.

OBJECTIVE: To assess the efficacy of non-hormonal, hyaluronic acid (HLA)-based vaginal gel in improving vulvovaginal estrogen-deprivation symptoms in women with a history of endometrial cancer. METHODS: For this single-arm, prospective, longitudinal trial, we enrolled disease-free women with a history of endometrial cancer who underwent surgery (total hysterectomy) and postoperative radiation. Participants used HLA daily for the first 2 weeks, and then 3×/week until weeks 12-14; dosage was then increased to 5×/week for non-responders. Vulvovaginal symptoms and pH were assessed at 4 time points (baseline [T1]; 4-6 weeks [T2]; 12-14 weeks [T3]; 22-24 weeks [T4]) with clinical evaluation, the Vaginal Assessment Scale (VAS), Vulvar Assessment Scale (VuAS), Female Sexual Function Index (FSFI), and Menopausal Symptom Checklist (MSCL). RESULTS: Of 43 patients, mean age was 59 years (range, 38-78); 54% (23/43) were partnered; and 49% (21/43) were sexually active. VAS, VuAS, MSCL, and SAQ (Sexual Activity Questionnaire) scores significantly improved from baseline to each assessment point (all p < .002). FSFI total mean scores significantly increased from T1 to T2 (p < .05) and from T1 to T4 (p < .03). At T1, 41% (16/39) felt confident about future sexual activity compared to 68% (17/25) at T4 (p = .096). Severely elevated vaginal pH (>6.5) decreased from 30% (13/43) at T1 to 19% (5/26) at T4 (p = .41). CONCLUSION: The HLA-based gel improved vulvovaginal health and sexual function of endometrial cancer survivors in perceived symptoms and clinical exam outcomes. HLA administration 1-2×/week is recommended for women in natural menopause; a 3-5×/week schedule appears more effective for symptom relief in cancer survivors.

OBJECTIVES: Assess outcomes of a clinical cohort of patients with endometrioid endometrial cancer (EEC) harboring somatic POLE exonuclease domain mutations (EDMs). METHODS: Patients were consented to a protocol of tumor-normal massively parallel sequencing of 410-468 cancer related genes. EECs subjected to sequencing from 2014 to 2018 were reviewed. Tumors with somatic POLE EDMs were identified. EECs were assessed for microsatellite instability (MSI) using MSIsensor and immunohistochemical analysis for mismatch repair (MMR) proteins. RESULTS: Of the 451 EECs sequenced, 23 had a POLE EDM (5%): 20 primary and 3 recurrent tumors sequenced. Nineteen cases (83%) were stage I/II and 4 (17%) were stages III/IV. Thirteen EECs (57%) were of FIGO grades 1/2, 10 (43%) grade 3. All patients were treated with surgery and 17 (89%) received adjuvant therapy. Five (22%) demonstrated loss of DNA MMR protein expression, none were due to Lynch syndrome. MSIsensor scores were conclusive for 21 samples: 19 were microsatellite stable and 2 MSI-high. After median follow-up of 30 months, 4/23 (17%) developed recurrences: 3 with initial grade 3 stage I and 1 with grade 1 stage III disease. One patient with grade 2 stage IV EEC had progressive disease after treatment. CONCLUSIONS: Patients with POLE EDM EEC have been shown to have a favorable prognosis. In this real-world cohort of patients, de novo metastatic disease and recurrences in initially uterine-confined cases were observed. Further research is warranted before incorporating the presence of POLE EDM into decision-making regarding adjuvant therapy.

OBJECTIVE: The aim of this study was to compare perioperative and oncologic outcomes between minimally invasive and open surgery in the treatment of endometrial carcinosarcoma. METHODS: We retrospectively identified all patients with newly diagnosed endometrial carcinosarcoma who underwent primary surgery via any approach at our institution from January 2009 to January 2018. Patients with known bulky disease identified on preoperative imaging were excluded. The χ2 and Mann-Whitney U tests were used to compare categorical and continuous variables, respectively. Kaplan-Meier curves were used to estimate survival, and compared using the log rank test. RESULTS: We identified 147 eligible patients, of whom 37 (25%) underwent an open approach and 110 (75%) underwent minimally invasive surgery. Within the minimally invasive group, 92 (84%) of 110 patients underwent a robotic procedure and 14 (13%) underwent a laparoscopic procedure. Four minimally invasive cases (4%) were converted to open procedures. Median age, body mass index, operative time, stage, complication grade, and use of adjuvant treatment were clinically and statistically similar between groups. Median length of hospital stay in the open group was 4 days (range 3-21) compared with 1 day (range 0-6) in the minimally invasive group (p<0.001). The rates of any 30-day complication were 46% in the open and 8% in the minimally invasive group (p<0.001). The rates of grade 3 or higher complications were 5.4% and 1.8%, respectively (p=0.53). Median follow-up for the entire cohort was 30 months (range 0.4-121). Two-year progression-free survival rates were 52.8% (SE±8.4) in the open group and 58.5% (SE±5.1) in the minimally invasive group (p=0.7). Two-year disease-specific survival rates were 66.1% (SE±8.0) and 81.4% (SE±4.1), respectively (p=0.8). CONCLUSIONS: In patients with clinical stage I endometrial carcinosarcoma, minimally invasive compared with open surgery was not associated with poor oncologic outcomes, but with a shorter length of hospital stay and a lower rate of overall complications.

PURPOSE: This study was designed to compare the observed risk of femoral fracture in primary soft-tissue sarcoma (STS) of the thigh/groin treated with intensity-modulated radiation therapy (IMRT) to expected risk calculated using the Princess Margaret Hospital (PMH) nomogram. METHODS: Expected femoral fracture risk was calculated by using the PMH nomogram. Cumulative risk of fracture was estimated by using Kaplan-Meier statistics. Prognostic factors were assessed with univariate and multivariate analysis using Cox's stepwise regression. RESULTS: Between February 2002 and December 2010, 92 consecutive eligible patients were assessed. Median follow-up was 73 months (106 months in surviving patients). IMRT was delivered preoperatively (50 Gy) in 13 (14%) patients and postoperatively in 79 (86%) patients (median dose, 63 Gy; range, 59.4-66.6 Gy). The observed crude risk of fractures was 6.5% compared with 25.6% expected risk from the nomogram; the cumulative risk of fracture using IMRT at 5 years was 6.7% (95% CI 2.8-16.0%). The median time to fracture was 23 months (range, 6.9-88.6). Significant predictors of fracture on univariate analysis were age ≥ 60 years (p = 0.03), tumor location in the anterior thigh (p = 0.008), and periosteal stripping to > 20 cm (p < 0.0001). On multivariate analysis, age ≥ 60 years and periosteal stripping > 20 cm retained significance (p = 0.04 and p = 0.009, respectively). CONCLUSIONS: In this study, the cumulative risk of femur fracture in patients treated with IMRT (6.7%) is less than the expected risk using the PMH nomogram (25.6%). Established predictors of femur fracture, such as gender, tumor size, and dose of RT, seem to have less impact on fracture risk when using IMRT.

OBJECTIVES: To assess outcomes after secondary surgical resection in patients with recurrent uterine leiomyosarcoma (uLMS). METHODS: We retrospectively identified all patients who had no evidence of disease after initial surgery for uLMS, who underwent surgery for a first recurrence at our institution between 1/1991 and 10/2013. We excluded patients who received any therapy for recurrence prior to secondary resection, and patients who underwent surgery soon after morcellation [of presumed benign fibroids] showed widespread disease. Overall survival (OS) was determined from time of first recurrence to death or last follow-up. RESULTS: We identified 62 patients: 29 with abdominal/pelvic recurrence only, 30 with lung recurrence only, 3 with both. Median time to first recurrence was 18â¯months (95% CI: 13.3-23.3): 15.8â¯months (95% CI: 13.0-18.6) abdominal/pelvic recurrence; 24.1â¯months (95% CI: 14.5-33.7) lung-only recurrence (pâ¯=â¯0.03). Median OS was 37.7â¯months (95% CI: 25.9-49.6) abdominal/pelvic recurrence; 78.1â¯months (95% CI: 44.8-11.4) lung recurrence (pâ¯=â¯0.02). Complete gross resection (CGR) was achieved in 58 cases (93%), with gross residual ≤1â¯cm in 2 (3.5%) and >1â¯cm in 2 (3.5%). Median OS based on residual disease was 54.1â¯months (95% CI: 24.9-83.3), 38.7â¯months (95% CI: NE), 1.7â¯months (95% CI: NE), respectively (pâ¯<â¯0.001). In cases with CGR, neither adjuvant radiation (Nâ¯=â¯9), chemotherapy (Nâ¯=â¯8) nor hormonal therapy (Nâ¯=â¯10) was associated with improved OS. CONCLUSIONS: Secondary surgical resection of recurrent uLMS is reasonable in patients with a high probability of achieving CGR. Lung-only recurrences were associated with more favorable outcome. Following CGR, additional therapy may not offer benefit.

OBJECTIVE: To evaluate clinical outcomes of patients with BRCA-associated ovarian cancer who developed brain metastases (BM). METHODS: Patients with epithelial ovarian, fallopian tube, and primary peritoneal cancer (EOC) and BM, treated at a single institution from 1/1/2008-7/1/2018, were identified from two institutional databases. Charts and medical records were retrospectively reviewed for clinical characteristics and germline BRCA mutation status. Appropriate statistics were used. RESULTS: Of 3649 patients with EOC, 91 had BM (2.5%). Germline mutation status was available for 63 (69%) cases; 21 (35%) of these harbored a BRCA1/2 mutation (15 BRCA1, 6 BRCA2). Clinical characteristics were similar between groups. BM were diagnosed at a median of 31â¯months (95% CI, 22.6-39.4) in BRCA-mutated (mBRCA) and 32â¯months (95% CI, 23.7-40.3) in wild-type BRCA (wtBRCA) (pâ¯=â¯0.78) patients. Brain metastases were the only evidence of disease at time of BM diagnoses in 48% (nâ¯=â¯10) mBRCA and 19% (nâ¯=â¯8) wtBRCA (pâ¯=â¯0.02) patients. There was no difference in treatment of BM by mutation status (pâ¯=â¯0.84). Survival from time of BM diagnosis was 29â¯months (95%CI, 15.5-42.5) in mBRCA and 9â¯months (95% CI, 5.5-12.5) in wtBRCA patients, with an adjusted hazard ratio (HR) of 0.53, pâ¯=â¯0.09; 95% CI, 0.25-1.11. HR was adjusted for presence of systemic disease at time of BM diagnosis. CONCLUSION: This is the largest study to date comparing outcomes in patients with EOC and BM by mutation status. mBRCA patients were more likely to have isolated BM, which may be a factor in their long survival. This supports the pursuit of aggressive treatment for mBRCA EOC patients with BM. Additional studies examining the correlation of BRCA mutational status with BM are warranted.
