Prostate-specific membrane antigen (PSMA) positron emission tomography (PET) scans have higher sensitivity and specificity for detecting lymph nodes or metastatic disease relative to conventional imaging in prostate cancer staging. Since its FDA approval and incorporation into treatment guidelines, the use of PSMA PET has increased in patients undergoing initial staging, those with recurrence after initial definitive treatment, and patients with metastatic disease. Although the early detection of metastatic lesions is changing disease management, it is unclear whether this impact on management translates into clinical benefit. This review will summarize evidence pertaining to the change in patient management due to PSMA PET use and will discuss the implications of PSMA PET on treatment decisions in prostate cancer, particularly in the settings of biochemical recurrence and metachronous oligometastatic disease.

Objective

Given that cervical cancer incidence rates do not decline in women >65, there is generally limited screening, and these women have a poor prognosis, it is imperative to better understand this population. We aim to describe the characteristics, treatment, and survival of women >65 diagnosed with cervical cancer.

Methods

SEER-Medicare 2004-2013 data was used to describe 2274 patients >65 diagnosed with cervical cancer. Five-year cancer-specific survival was estimated using the Kaplan-Meier method. Multivariable Poisson and Cox regression analyses identified characteristics associated with treatment and mortality.

Results

The median age was 76.1 years, with nearly one-third of cases occurring in women >80 years. Most patients were non-Hispanic White (64.8%), had comorbidity scores ≥ 1 (53.9%) and squamous histology (66.3%). Most women were diagnosed at stage II or higher (62.7%), including nearly one-quarter at Stage IV (23.1%). Nearly 15% of patients were not treated (14.6%). Lack of treatment was associated with oldest age (>80), comorbidity scores ≥3, and stage IV disease. Five-year cancer-specific survival was 50%. Increasing age and stage at diagnosis were significantly associated with lower cancer-specific survival whereas treatment was strongly associated with increased survival.

Conclusion

Most women >65 with cervical cancer are diagnosed with locally advanced or metastatic disease and many do not receive treatment. Survival is improved with early-stage diagnosis and treatment. These findings, coupled with the fact that women >65 constitute an increasing proportion of the population, highlight the need to re-evaluate screening and treatment practices in this population to detect cervical cancer at earlier stages and increase survival.

Novelty and impact statement

In SEER-Medicare linked data from 2004 to 2013, most women >65 with cervical cancer were diagnosed with locally advanced or metastatic disease. Both receipt of treatment and survival decreased with increasing age. These findings, coupled with the fact that women aged >65 constitute an increasing proportion of the population, highlight the need to re-evaluate screening and treatment practices in older women to detect cervical cancer at earlier stages and increase survival.

A disproportionate burden of gynecologic malignancies occurs in low- and middle-income countries. Radiation therapy is an integral component of treatment for gynecologic malignancies both from a curative (locally advanced cervical cancer) and palliative (bleeding cervical or pelvic mass) standpoint. Critical to understanding how better to serve patients in this regard is understanding both the extent of disease epidemiology and the radiotherapy infrastructure to treat these diseases. In this review, we explore various geographic regions and how they address a unique set of challenges specific to the peoples and culture of the region. We identify common threads across regions, including sparse distribution of radiation equipment, geographic access, and specialized training. We also highlight examples of success in the use of telemedicine and cross-cultural partnerships to help bolster access to training to ensure increased access to adequate and appropriate treatment of gynecologic malignancies.

The COVID-19 pandemic has forever affected healthcare and posed an incredible challenge to our society to care for our sick. Patients with cancer were found early on to have higher rates of complications with COVID-19. Radiation therapy is an integral part of treatment for many types of gynecologic cancer and adaptation on its utilization during the pandemic varied across the globe. In this review, we detail certain guidelines for the use of radiation in gynecologic cancers during the pandemic as well as real world accounts of how different countries adapted to these guidelines or created their own based on individualized resources, staffing, government restrictions, and societal norms. Critically, this review demonstrates the breadth of fractionation schemes and technologies used when resources were limited but highlights the importance of long term follow-up for many of our patients during this time.

PURPOSE: The effect of climate-driven events, such as wildfires, on health care delivery and cancer care is a growing concern. Patients with cancer undergoing radiation therapy are particularly vulnerable to treatment interruptions, which have a direct effect on survival. We report the results of a study characterizing the effect of wildfires on radiation oncology clinics and their patients. METHODS AND MATERIALS: A survey of California radiation oncologists was used to evaluate emergency preparedness and the effect of wildfires on the delivery of radiation therapy services between 2017 and 2022. Descriptive statistics and Pearsons χ2 tests were performed to investigate potential relationships between provider characteristics, practice settings, and perceptions of the effect of wildfire events. California Department of Forestry and Fire Protection data were employed to map the geographic distribution of wildfires to clinic locations. RESULTS: Response rate was 12.3% (51/415 radiation oncologists), representing 25% of clinics (43/176) in 41% (24/58) of California counties. Sixty-one percent (31/51) of respondents reported being affected by a wildfire, 2 of which are rural clinics (100%, 2/2) and 29 are (59%, 29/49) metropolitan practices. Of these, 18% (9/51) reported a clinic closure, and 29% (15/51) reported staffing shortages. Respondents reported effects on patients, including having to evacuate (55%, 28/51), cancel/reschedule treatments (53%, 27/51), and experiencing physical, mental, or financial hardship due to wildfires (45%, 23/51). Respondents described effects on clinical operations, including being forced to transfer patients (24%, 12/51), transportation interruptions (37%, 19/51), regional/community evacuations (35%, 18/51), and physical/mental health effects (27%, 14/51) on clinic personnel. Less than half of the respondents (47%, 24/51) reported their workplace had a wildfire emergency preparedness plan. Additionally, geographic analysis revealed that 100% (176/176) of clinics were located within 25 miles of a wildfire. CONCLUSIONS: This study highlights the effects of wildfires on radiation oncology clinics and patients and underscores the need for emergency preparedness planning to minimize the consequences of such disasters.

Purpose

Recruitment to radiation oncology training programs has recently declined, and gender inequities persist in radiation oncology. Policies that promote inclusivity, such as the updated American College of Graduate Medical Education parental leave policy establishing minimum parental leave requirements, may support recruitment to radiation oncology.

Methods and materials

We surveyed 2021-2022 radiation oncology residency applicants and program directors (PDs) about program-specific parental leave policies, transparency of parental leave information during the residency application and interview process, and perceptions of the effect of parenthood on residency training, career advancement, and well-being.

Results

Of 89 radiation oncology PDs, 29 (33%) completed the survey. Of 154 residency applicants (current fourth-year medical students, international applicants, or postdoctoral fellows) surveyed, 62 (40%) completed the survey. Most applicants planned to start a family during residency (53%) and reported perceived flexibility to start a family influenced their decision to pursue radiation oncology over other career specialties (55%). Many applicants viewed time in residency (nonresearch, 22%), in research (33%), and as early career faculty (24%) as the best time to start a family. A small number of applicants used program-specific parental leave policy information in determining their rank list (11%), and many applicants sought information regarding fertility health care benefits (55%). Many applicants obtained parental leave information verbally, despite expressing a preference for objective means (slide deck, 63%; website, 50%; or handout, 42%) of information sharing. PDs were all supportive of a 6-week maternity leave policy (100% agree or strongly agree with the policy) and did not feel parental leave would negatively affect a resident's ability to pursue an academic (100%) or private practice career (100%).

Conclusions

Many radiation oncology residency applicants plan to start families during training, seek and value program-specific parental leave information and health benefits, and prefer objective means of information sharing. These findings likely reflect those who have strong views of parental leave policies.

Introduction

Brachytherapy is an essential component of the cervical cancer treatment paradigm as it contributes to improved clinical outcomes and overall survival. Yet brachytherapy remains globally underutilized, with disparities in access at both national and international levels.

Areas covered

The review explores current brachytherapy utilization practices and efforts being undertaken to address barriers to implementation in low-, middle-, and high-income countries, and how these efforts are projected to impact future brachytherapy access. The content presented is based on a review of published literature and the authors' collective clinical experiences.

Expert opinion

There exists a tremendous opportunity to expand access to essential brachytherapy services for women with cervical cancer. Many national and international brachytherapy efforts exist; yet it remains imperative that such focused efforts continue to grow and provide further access to this critical treatment modality for women in need worldwide.

PURPOSE: We aimed to examine the impact of different conference formats (in-person, virtual, and hybrid) of the ASCO conference on greenhouse gas (GHG) emissions and to recommend sustainable options for future conferences. MATERIALS AND METHODS: This study used data on the number of attendees, their departure locations, and the type of attendance (in-person v virtual) provided by ASCO between 2019 and 2022. The GHG emissions resulting from air and ground travel, remote connectivity, conference space utilization, hotel stays, distributed conference materials, and electricity use were estimated for each year. Emissions were stratified by attendee country of origin, type of attendance, and year. Simulations were conducted to evaluate how changes in conference size, location, and format impact emissions, as well as estimate the resulting mitigations from adopting the proposed changes. RESULTS: The highest estimated GHG emissions, calculated in carbon dioxide equivalents (CO2e), were associated with the 2019 in-person conference (37,251 metric tons of CO2e). Although international attendees had the largest contribution to emissions in all years (>50%), location optimization models, which selected conference locations that most minimized GHG emissions, yielded only minimal reductions (approximately 3%). Simulations examining changes to the conference format, location, and attendance percentage suggested that hub-and-spoke, where multiple conference locations are selected by global region, or hybrid models, with both in-person and virtual components, are likely to cause the largest drops in emissions (up to 86%). CONCLUSION: Using historical conference data, this study identifies key aspects that can be modified to reduce emissions and consequently promote more sustainable and equitable conference attendance. Hybrid conferences may be the best solution to maintain the networking opportunities provided by conferences while balancing out their environmental footprint.

PURPOSE: Although recent technological advances in radiation therapy have significantly improved treatment outcomes, the global distribution of radiation therapy is unbalanced, making access especially challenging for patients in rural or low-resource settings because of travel burden. This systematic review aimed to explore the impact of geographic distance to treatment facilities on survival, as well as other treatment outcomes, among patients undergoing radiation therapy. METHODS AND MATERIALS: A search of four databases (PubMed, Embase, CINAHL, and Web of Science) was performed. Studies were included if they were primary literature, published between May 2000 and May 2023, and reported the travel distances for patients undergoing radiation therapy for malignant conditions and its influence on survival outcomes. Studies were excluded if they did not report primary outcomes, were published before 2000, or were non-English. RESULTS: After review, 23 studies were included. Most studies were conducted in the United States, with cervical cancer being the most frequently studied disease site. Data suggested that travel distances vary significantly, with patients often traveling a median distance of 20 miles to radiation therapy. Among the studies, 5 reported a negative impact on overall survival, often associating greater travel with nonadherence to recommended care. Other survival metrics, including progression-free survival and all-cause mortality, were also assessed, demonstrating similar variability in relation to travel distance. Conversely, seven studies found no significant impact on overall survival, and four suggested a positive impact on overall survival, with improved outcomes at centers with higher case volumes. Some data also revealed an inverse correlation between travel distance and the likelihood of receiving guideline-concordant radiation therapy. CONCLUSIONS: The impact of travel distance on radiation therapy outcomes is varied. Our findings underscore the challenges posed by travel in accessing radiation therapy and the disparities affecting particular patient demographic groups. Additional studies are needed to thoroughly assess the impacts of geographic disparities and to identify effective measures to address these challenges.

Objective

To present the stage distribution, patterns of care, and outcomes of patients from Botswana with invasive cervical cancer, living with or without HIV.

Methods

Between 2013 and 2020, women with cervical cancer were prospectively enrolled in an observational cohort study.

Results

A total of 1,043 patients were enrolled; 69% were women living with HIV. The median age of the cohort was 47 years (interquartile range [IQR] 40-58 years), with women living with HIV presenting at a younger age compared to women without HIV (44 versus 61 years, p < 0.001). Among women living with HIV, the median CD4 count at the time of cancer diagnosis was 429.5 cells/μL (IQR 240-619.5 cells/μL), 13% had a detectable viral load, and 95% were on antiretroviral therapy. In regard to treatment, 6% (n = 58) underwent surgery, 33% (n = 341) received radiation therapy, 51% (n = 531) received chemoradiation, and 7% (n = 76) did not receive treatment. Stage distribution in the cohort was as follows: I 17% (n = 173), II 37% (n = 388), III 35% (n = 368), and IV 8% (n = 88). For all patients, 2-year OS was 67%. In multivariable Cox regression, worse OS was associated with stage: II (HR 1.91, p = 0.007), III (HR 3.99, p < 0.001), and IV (HR 5.06, p < 0.001) compared to stage I. Improved OS was associated with hemoglobin > 10 g/dL (HR 0.51, p < 0.001) compared to Hb ≤ 10 g/dL.

Conclusions

Among women in Botswana with cervical cancer, most patients presented with stage II or III disease warranting radiation therapy or chemoradiation. While two-thirds of cervical cancer patients were women living with HIV, HIV did not impact OS.
