RESUMEN
BACKGROUND: Breast-conserving surgery (BCS) followed by adjuvant radiotherapy (RT) is a standard treatment for ductal carcinoma in situ (DCIS). A low-risk patient subset that does not benefit from RT has not yet been clearly identified. The DCISionRT test provides a clinically validated decision score (DS), which is prognostic of 10-year in-breast recurrence rates (invasive and non-invasive) and is also predictive of RT benefit. This analysis presents final outcomes from the PREDICT prospective registry trial aiming to determine how often the DCISionRT test changes radiation treatment recommendations. METHODS: Overall, 2496 patients were enrolled from February 2018 to January 2022 at 63 academic and community practice sites and received DCISionRT as part of their care plan. Treating physicians reported their treatment recommendations pre- and post-test as well as the patient's preference. The primary endpoint was to identify the percentage of patients where testing led to a change in RT recommendation. The impact of the test on RT treatment recommendation was physician specialty, treatment settings, individual clinical/pathological features and RTOG 9804 like criteria. Multivariate logisitc regression analysis was used to estimate the odds ratio (ORs) for factors associated with the post-test RT recommendations. RESULTS: RT recommendation changed 38% of women, resulting in a 20% decrease in the overall recommendation of RT (p < 0.001). Of those women initially recommended no RT (n = 583), 31% were recommended RT post-test. The recommendation for RT post-test increased with increasing DS, from 29% to 66% to 91% for DS <2, DS 2-4, and DS >4, respectively. On multivariable analysis, DS had the strongest influence on final RT recommendation (odds ratio 22.2, 95% confidence interval 16.3-30.7), which was eightfold greater than clinicopathologic features. Furthermore, there was an overall change in the recommendation to receive RT in 42% of those patients meeting RTOG 9804-like low-risk criteria. CONCLUSIONS: The test results provided information that changes treatment recommendations both for and against RT use in large population of women with DCIS treated in a variety of clinical settings. Overall, clinicians changed their recommendations to include or omit RT for 38% of women based on the test results. Based on published clinical validations and the results from current study, DCISionRT may aid in preventing the over- and undertreatment of clinicopathological 'low-risk' and 'high-risk' DCIS patients.

OBJECTIVE: To investigate whether performing a lymph node dissection during hysterectomy improves overall survival in patients with clinical stage III endometrial cancer who received neoadjuvant chemotherapy. METHODS: The National Cancer Database was queried to identify all patients with clinical stage III endometrial cancer who had undergone pre-operative chemotherapy as first course of treatment followed by hysterectomy with or without lymph node dissection between the years 2004 and 2020. Univariable and multivariable models were performed to investigate prognostic factors on overall survival. RESULTS: This study analyzed 2882 patients with clinical stage III endometrial cancer who received upfront chemotherapy. Among those who underwent lymph node dissection, 38% had positive lymph nodes. Factors found to be independently associated with improved survival included lymph node dissection (p<0.001), adjuvant radiation (p<0.001), histology (p<0.001), tumor grade (p<0.001), pathologic node status (p<0.001), age (p<0.001), type of insurance (p=0.027), and race (p<0.001). Patients who underwent lymph node dissection at time of hysterectomy had a significantly better overall survival (107 vs 85 months; p<0.001). Multivariate and propensity score analyses robustly demonstrated that lymph node dissection significantly improved overall survival (HR 0.69, 95% CI 0.57 to 0.84, p<0.001), even among patients with pathologically negative lymph nodes. CONCLUSION: Our study suggests that performing lymph node dissection at the time of hysterectomy is associated with improved overall survival in all patients with stage III endometrial cancer who receive upfront chemotherapy, regardless of age, race, insurance status, histologic subtype, tumor grade, pathologic node status, adjuvant radiation or chemotherapy. Notably, patients with high-risk disease may particularly benefit from this approach.
RESUMEN
Vulvar cancer is rare, and unresectable disease provides a therapeutic conundrum. Although definitive surgery remains the mainstay for curative treatment of vulvar cancer, a minority of patients present with advanced disease for which surgical resection would be extraordinarily morbid. Pre-operative and definitive radiation with radiosensitizing systemic therapy allows such patients an opportunity for cure. In this review, we explore the origins of pre-operative radiation, current treatment standards for pre-operative and definitive chemoradiation, and future directions.

Freehand needles can be used with multichannel vaginal cylinders (MCVC) to cover vaginal cancer >7 mm thick or with supra-vaginal extension. We report our institutional outcomes using this novel hybrid technique. Patients with vaginal malignancies treated with HDR BT using MCVC plus freehand needles from 2014-2021 at our institution were identified. Clinical characteristics, details of brachytherapy, initial response, and overall local control (LC) outcomes were recorded. LC was analyzed via Kaplan-Meier method. 34 patients were identified with median follow-up 1.9 years. 19 patients had primary endometrial cancer with vaginal recurrence/disease, and remaining had primary vaginal cancer or other primaries. 7 patients had recurrence after previous RT course. 25 patients received EBRT with median dose 45 Gy in 25 fractions, and rest received BT alone. Median HR-CTV D90 for patients treated with EBRT plus BT was 77.4 Gy. 30 patients had complete local response to BT on initial examination and/or follow-up imaging. 1 and 2-year LC rates in patients without prior RT treated with EBRT + BT were 94.1% and 94.1%, respectively. 1 and 2-year LC rates for those without prior RT were 88.1% and 76.4%, respectively. 1 and 2-year LC rates for those with prior RT were 68.6% and 34.3%, respectively. 1 patient had vaginal laceration requiring surgical repair, and 1 patient developed small bowel obstruction 1 month after BT, with no additional acute grade 3+ toxicities identified. Our approach with MCVC plus freehand needles with MRI-based planning was feasible and safe, with excellent initial local response and low rate of serious toxicities.

Purpose: An initiative to advocate for those underrepresented in radiation oncology. Methods and Materials: Inspired by the success of the #ILookLikeAnEngineer and #ILookLikeASurgeon campaigns, this initiative aimed to break down stereotypes in traditionally male-dominated fields. In honor of Marie Curie's birthday, on November 7, 2018, the Society for Women in Radiation Oncology launched a social media campaign called #WomenWhoCurie day. However, as the popularity of the social media campaign increased, it become evident that members of the wider radiation community, in particular women of color, nonbinary and transgender people did not feel supported by the #WomenWhoCurie movement. In November 2021, after consultation with diversity and inclusion leaders and members of other national radiation oncology organizations, Society for Women in Radiation Oncology launched #WeWhoCurie alongside the #WomenWhoCurie campaign for women and gender minorities in radiation oncology. Radiation oncologists, physicists, dosimetrist, therapists, nurses, and other professionals from around the world gathered and shared photos and social media posts throughout the day on multiple platforms including Facebook, Instagram, and Twitter. Results: In the year #WeWhoCurie, #WomenWhoCurie, #_______ WhoCurie campaign launched, we saw an increase in participation across the globe from 9 countries: the United States, Canada, Mexico, Brazil, Italy, Spain, China, New Zealand, and Australia. There were over 720 tweets contributing to the campaign with over 2000 messages, representing 3,365,444 "potential impacts", or the number of times someone saw the hashtag. Conclusions: Through this campaign we aim to celebrate the incredible women, gender minorities, and allies who are "Curie-ing" patients with cancer and conducting cutting edge research to improve cancer care across the globe. As an organization we believe adding our voices to the masses will foster a culture of inclusion for everyone. Afterall, what good is the practice of radiation oncology if all are not equally welcome?
RESUMEN
Women and historically excluded minorities are underrepresented in clinical research. At the ASTRO 2021 annual meeting, the authors reviewed several strategies to improve on this issue. Implementation of such strategies should not only improve their visibility but also provide increased opportunities for their advancement and work in clinical research.
RESUMEN
Importance: Pathologic complete response (pCR) may be associated with prognosis in patients with soft tissue sarcoma (STS). Objective: We sought to determine the prognostic significance of pCR on survival outcomes in STS for patients receiving neoadjuvant chemoradiotherapy (CT-RT) (Radiation Therapy Oncology Group [RTOG] 9514) or preoperative image-guided radiotherapy alone (RT, RTOG 0630) and provide a long-term update of RTOG 0630. Design, Setting, and Participants: RTOG has completed 2 multi-institutional, nonrandomized phase 2 clinical trials for patients with localized STS. One hundred forty-three eligible patients from RTOG 0630 (n = 79) and RTOG 9514 (n = 64) were included in this ancillary analysis of pCR and 79 patients from RTOG 0630 were evaluated for long-term outcomes. Intervention: Patients in trial 9514 received CT interdigitated with RT, whereas those in trial 0630 received preoperative RT alone. Main Outcomes and Measures: Overall and disease-free survival (OS and DFS) rates were estimated by the Kaplan-Meier method. Hazard ratios (HRs) and P values were estimated by multivariable Cox model stratified by study, where possible; otherwise, P values were calculated by stratified log-rank test. Analysis took place between December 14, 2016, to April 13, 2017. Results: Overall there were 42 (53.2%) men; 68 (86.1%) were white; with a mean (SD) age of 59.6 (14.5) years. For RTOG 0630, at median follow-up of 6.0 years, there was 1 new in-field recurrence and 1 new distant failure since the initial report. From both studies, 123 patients were evaluable for pCR: 14 of 51 (27.5%) in trial 9514 and 14 of 72 (19.4%) in trial 0630 had pCR. Five-year OS was 100% for patients with pCR vs 76.5% (95% CI, 62.3%-90.8%) and 56.4% (95% CI, 43.3%-69.5%) for patients with less than pCR in trials 9514 and 0630, respectively. Overall, pCR was associated with improved OS (P = .01) and DFS (HR, 4.91; 95% CI, 1.51-15.93; P = .008) relative to less than pCR. Five-year local failure rate was 0% in patients with pCR vs 11.7% (95% CI, 3.6%-25.1%) and 9.1% (95% CI, 3.3%-18.5%) for patients with less than pCR in 9514 and 0630, respectively. Histologic types other than leiomyosarcoma, liposarcoma, and myxofibrosarcoma were associated with worse OS (HR, 2.24; 95% CI, 1.12-4.45). Conclusions and Relevance: This ancillary analysis of 2 nonrandomized clinical trials found that pCR was associated with improved survival in patients with STS and should be considered as a prognostic factor of clinical outcomes for future studies. Trial Registration: ClinicalTrials.gov Identifiers: RTOG 0630 (NCT00589121); RTOG 9514 (NCT00002791).

Partial breast irradiation (PBI) has been increasingly accepted as a suitable component of breast conservation in the management of patients with early stage breast cancer, however the majority of existing studies have focused on the use of adjuvant or intra-operative techniques. Several early stage studies have more recently shown that PBI can be safely used in the pre-operative setting. Early data show similar local control without evidence of increased toxicity or worsening cosmesis, as compared to postoperative PBI or standard whole breast irradiation. While long term data are still maturing, pre-operative accelerated PBI (PAPBI) offers a number of possible clinical advantages including reducing the treatment field and increasing the number of patients eligible for PBI, identifying biomarkers of response to radiation, and improving the rates of breast conservation and treatment compliance. This review discusses key concepts and controversies surrounding PBI as it has increasingly been adopted in the US, Canada, and Europe, and introduces the concepts and early studies of PAPBI. In addition, we summarize ongoing clinical trials investigating PAPBI, review clinical benefits and challenges associated with PAPBI versus postoperative PBI, and discuss ongoing limitations as well as next generation technologies important to the implementation of PAPBI in the management of patients with early-stage localized breast cancer.
RESUMEN
PURPOSE: The High-Dose-Rate (HDR) vaginal cylinder treatment is typically designed using the initial CT, while the subsequent implants are verified using rudimentary methods (i.e., visual inspection, ruler measurements, etc.) and/or X-ray imaging. We are proposing the use of a 3D-printed individualized template that could provide simple and reproducible vaginal cylinder insertion. MATERIAL AND METHODS: Six patients were included in the study with prescriptions of 6 Gy/fraction for 2 to 5 fractions (total 27 treatments). The first 1 to 2 treatments were delivered without the template and the rest with the CT-based 3D-printed templates. Cone beam CTs (CBCTs) were acquired to verify the cylinder placement for all treatments. D2cc of the bladder and rectum are recorded on both planning CT and the following on-treatment CBCTs. RESULTS: By using the templates, the tip position variation on average (±1 SD) reduced from 0.8±0.5 cm to 0.6±0.4 cm, and angular difference decreased from 5.3±3.5° to 4.7±2.4°. The pitch and yaw deviation are reduced from 0.9 ± 5.8° and 0.4±2.9° to 0.0±3.9° and -0.2±3.0°, respectively. The deviation of D2cc to bladder from the plan reduced from 6±4% to 5±3%, and rectum from 5±2% to 4±4%. CONCLUSION: The 3D-printed patient-specific cylinder templates could potentially improve the geometrical reproducibility of cylinder treatments at no cost of additional imaging. The D2cc for the bladder and rectum are determined by the treatment length rather than their respective volumes.

Age is one of the most important risk factors for the development of breast cancer. Nearly a third of all breast cancer cases occur in older women (aged ≥70 years), with most cases being oestrogen receptor-positive (ER+). Such tumours are often indolent and unlikely to be the ultimate cause of death for older women, particularly when considering other comorbidities. This Review focuses on unique clinical considerations for screening, detection, and treatment regimens for older women who develop ER+ breast cancers-specifically, we focus on recent trends for de-implementation of screening, staging, surgery, and adjuvant therapies along the continuum of care. Additionally, we also review emerging basic and translational research that will further uncover the unique underlying biology of these tumours, which develop in the context of systemic age-related inflammation and changing hormone profiles. With prevailing trends of clinical de-implementation, new insights into mechanistic biology might provide an opportunity for precision medicine approaches to treat patients with well tolerated, low-toxicity agents to extend patients' lives with a higher quality of life, prevent tumour recurrences, and reduce cancer-related burdens.

Vaginal oligometastatic disease of colorectal primary is a rare malignancy with few reported cases in the literature and no standardized treatment paradigm. We report on the definitive management of an unusual case of an elderly woman with the aforementioned disease. A 78-year-old African-American woman presented with vaginal spotting and was found to have a vaginal lesion. Final pathology was consistent with moderately differentiated adenocarcinoma of colorectal primary. Extensive work up, which included endoscopies, pathologic analyzes, and imaging workup, did not reveal a primary gastrointestinal malignancy. The patient underwent partial vaginectomy and final pathology once again confirmed moderately differentiated adenocarcinoma of colorectal primary (CDX 2 and CEA positive, ER/PR, and CK 7 negative) with negative margins. She went on to receive adjuvant concurrent chemoradiation with 5-FU based chemotherapy. She received 45 Gy in 25 fractions to the whole pelvis followed by an HDR brachytherapy boost to 12 Gy in two fractions. Unfortunately, 10 months after completing radiation, she was found to have adenocarcinoma arising from a hepatic flexure colon polyp on colonoscopy. She required definitive surgical resection and was staged as mpT3N0M1. She received 12 cycles of 5-FU and at 2-year follow-up was found to be disease free with no evidence of locoregional recurrence or distant metastatic disease. Continued long-term follow up is warranted.
RESUMEN
Secretory carcinoma is a rare and indolent breast cancer with a lack of established treatment paradigms. We describe a case of a woman who underwent breast conservative therapy in the modern era. A 48 year old woman with a screen-detected left breast cancer was found to have early-stage secretory carcinoma after definitive breast conservation surgery. Further management with adjuvant radiation was recommended. After definitive breast conservative surgery, final pathology was notable for secretory breast carcinoma due to the immunohistologic characteristics of the tumor, ETV6-NTRK3 gene fusion, and histologic findings. After multi-disciplinary discussion, it was recommended that the patient proceed with adjuvant radiation. She was treated using a modestly hypofractionated regimen of 4256 cGy in 16 fractions. She tolerated the treatment well, developing only grade 1 radiation dermatitis. At 1 year follow-up she was clinically and radiographically free of disease. With a shift in management toward breast conservative therapy, defining the role of adjuvant radiation for secretory carcinomas in the modern era is of increasing importance. Modestly hypofractionated radiation is well-tolerated. Oncologic outcomes will be assessed with continued long-term follow-up.
RESUMEN
Implicit bias is one of the most insidious and least recognizable mechanisms that can cause inequity and disparities. There is increasing evidence that both implicit and explicit biases have a negative effect on patient outcomes and patient-physician relationships. Given the impact of Implicit bias, a joint session between ASTROs Committee on Health Equity, Diversity, and Inclusion and the National Cancer Institute (the ASTRO-National Cancer Institute Diversity Symposium) was held during the American Society of Radiation Oncology (ASTRO) 2020 Annual Meeting, to address the effect of implicit bias in radiation oncology through real life and synthesized hypothetical scenario discussions. Given the value of this session to the radiation oncology community, the scenarios and discussion are summarized in this manuscript. Our goal is to heighten awareness of the multiple settings in which implicit bias can occur as well as discuss resources to address bias.
RESUMEN
PURPOSE: American Brachytherapy Society (ABS) guidelines recommend using a 3-5 cm active length (AL) when treating vaginal cuff (VC) in adjuvant setting of endometrial cancer (EC). The purpose of this study was to evaluate local control and toxicity, using an AL of 1 or 2 cm and immobilization with a traditional table-mounted (stand) or patient-mounted (suspenders) device. MATERIAL AND METHODS: Between 2005 and 2019, 247 patients with EC were treated with adjuvant high-dose-rate vaginal cuff (HDR-VC) brachytherapy with or without external beam radiation (EBRT). Treatment was prescribed to a 0.5 cm depth, with an AL of 1 or 2 cm, using stand or suspenders. VC boost after EBRT was typically administered with 2 fractions of 5.5 Gy, while VC brachytherapy alone was typically applied with 3 fractions of 7 Gy or 5 fractions of 5.5 Gy. RESULTS: The combination of suspender immobilization and an AL of 2 cm (n = 126, 51%) resulted in 5-year local control of 100%. An AL of 2 cm compared to 1 cm correlated with better local control (99.1% vs. 88.5%, p = 0.0479). Regarding immobilization, suspenders correlated with improved local control compared to stand (100% vs. 86.7%, p = 0.0038). Immobilization technique was significantly correlated with AL (p < 0.0001). Only 5 (2.0%) patients experienced grade ≥ 3 toxicity, all of whom received EBRT. CONCLUSIONS: In the present series, an AL of 2 cm provided excellent local control, while 1 cm was inadequate. Suspender immobilization was a practical alternative to stand immobilization in HDR brachytherapy of the vaginal cuff.
RESUMEN
The proportion of female trainees in radiation oncology has generally declined despite increasing numbers of female medical students; as a result, radiation oncology is among the bottom 5 specialties in terms of the percentage of female applicants. Recently, social media has been harnessed as a tool to bring recognition to underrepresented groups within medicine and other fields. Inspired by the wide-reaching social media campaign of #ILookLikeASurgeon to promote female physicians, members of the Society for Women in Radiation Oncology penned a new hashtag and launched the #WomenWhoCurie social media campaign on Marie Curie's birthday November 7th, as part of their strategy to raise public awareness. From November 6, 2018 until November 10, 2018, the #WomenWhoCurie hashtag delivered 1,135,000 impressions, including 408 photos from all over the world including United States, Spain, Canada, France, Australia, Ireland, the United Kingdom, Mexico, Japan, the Netherlands, India, Ecuador, Panama, Brazil, and Nigeria. Alongside continued gender disparity research, social media should continue to be used as a tool to engage the community and spur conversations to formulate solutions for gender inequity.
RESUMEN
PURPOSE: Palbociclib is a selective cyclin-dependent kinase 4/6 inhibitor approved for metastatic ER+/HER2- breast cancer. Preclinical evidence suggests a possible synergistic effect of palbociclib when combined with radiation therapy (RT); however, the toxicity of this pairing is unknown. We report preliminary results on the use of this combination. METHODS AND MATERIALS: Records of patients treated with palbociclib at our institution from 2015 to 2018 were retrospectively reviewed. Patients who received RT for symptomatic metastases concurrently or within 14 days of palbociclib were included. Local treatment effect was assessed by clinical examination and subsequent computed tomography/magnetic resonance imaging. Toxicity was graded based on Common Terminology Criteria for Adverse Events version 5.0. RESULTS: A total of 16 women received palliative RT in close temporal proximity to palbociclib administration. Four patients received palbociclib before RT (25.0%), 5 concurrently (31.3%), and 7 after RT (43.8%). The median interval from closest palbociclib use to RT was 5 days (range, 0-14). The following sites were irradiated in decreasing order of frequency: bone (11 axial skeleton [9 vertebra and 2 other]; 4 pelvis; 3 extremity), brain (4: 3 whole brain RT and 1 stereotactic radiosurgery), and mediastinum (1). The median and mean follow-up time is 14.7 and 17.6 months (range, 1.7-38.2). Pain relief was achieved in all patients. No radiographic local failure was noted in the 13 patients with evaluable follow-up imaging. Leukopenia, neutropenia, and thrombocytopenia were seen in 4 (25.0%), 5 (31.3%), and 1 (6.3%) patient before RT. After RT, 5 (31.3%), 1 (6.3%), and 3 (18.8%) patients were leukopenic, neutropenic, and thrombocytopenic, respectively. All but 2 (grade 2) hematologic toxicities were grade 1. No acute or late grade 2+ cutaneous, neurologic, or gastrointestinal toxicities were noted. Toxicity results did not differ based on disease site, palbociclib-RT temporal association, or irradiated site. CONCLUSIONS: The use of RT in patients receiving palbociclib resulted in minimal grade 2 and no grade 3+ toxicities. This preliminary work suggests that symptomatic patients receiving palbociclib may be safely irradiated.
RESUMEN
PURPOSE: To examine the role of radiation oncology (RO) graduates' application patterns and personal preferences in current labor concerns. METHODS AND MATERIALS: An anonymous, voluntary survey was distributed to 665 domestic RO graduates from 2013 to 2017. Questions assessed graduates' regional (Northeast [NE]; Midwest [MW]; South [SO]; West [WT]) job type and population size preferences. Top regional choice was compared across other categorical and numerical variables using the χ2 test and analysis of variance, respectively. RESULTS: Complete responses were obtained from 299 (45.0% response rate) participants: 82 (27.4%), 74 (24.7%), 85 (28.4%), and 58 (19.4%) graduated from NE, MW, SO, and WT programs. The most to least commonly applied regions were SO (69.2%), MW (55.9%), and then NE/WT (55.2% each). The first and last regional choices were the WT (29.4%) and MW (15.7%), respectively. The most and least common application and top choice preferences were consistent in terms of city size: >500,000 (86.0% and 64.5%, respectively) and <100,001 (26.1% and 7.0%, respectively). The majority of applicants applied to both academic and nonacademic positions (60.9%), with top job type choice being equally split. The majority of respondents independently received a job offer in their preferred region (75.3%), city population size (72.6%) or job type (81.9%). Additionally, 52.5% received a job offer that included all three preferences. Those who underwent residency training (44.3% vs 62.0%-83.6%, P < .001) or medical schooling (50.7% vs 56.3%-75.6%, P < .001) or grew up in the MW (60.8% vs 70.0%-74.7%, P < .001) were least likely to choose this region as their top regional choice compared with other regions. CONCLUSIONS: The MW and jobs in smaller cities are less appealing to RO graduates, even if they receive training in the MW, which may contribute to current job market concerns. Nonetheless, the majority of respondents received a job offer in the region, population size, and job type of their top choice. Assessing prospective candidates' city size and geographic preferences and prioritizing applicants who are compatible with positions may help address potential job market discrepancies.
