Purpose: The addition of pembrolizumab to chemotherapy in high-risk early triple-negative breast cancer (TNBC) improves cancer outcomes. However, pembrolizumab induces varied immune-related adverse events (irAEs) where some can be severe or lifelong. This retrospective study describes real-world patterns of irAEs in patients with TNBC who received pembrolizumab.
Methods: We evaluated irAEs in patients with TNBC from a comprehensive cancer center and a community hospital who received pembrolizumab with chemotherapy between 2021 and 2023, excluding those enrolled in clinical trials. We used national guidelines to grade toxicities. Logistic regression assessed the effect of clinicopathologic variables on irAEs adjusting for covariates.
Results: We identified 233 patients with a median age of 51 years, 62% had stage II TNBC, 35% had stage III TNBC, 25% were Hispanic, 21% were Black, and 42% were White. Eighty patients (34%) developed 100 separate irAEs. The most common irAEs were endocrinopathies (52%) and GI (23%); there were 26 grade ≥3 irAEs, which all resulted in hospitalization, the most common being GI (13 instances); 45 required systemic steroids, 16 required additional immunosuppressive therapy, and 32 patients discontinued pembrolizumab because of irAEs. Two patients who developed colitis eventually died due to complications. Most (67 instances) irAEs were unresolved at the time of last follow-up, but 55% (37/67) had improved to grade 1. No clinicopathologic factors were associated with the development or severity of irAEs.
Conclusion: In this real-world diverse population, we observed rates of irAEs comparable with KEYNOTE-522, where endocrinopathies were the most prevalent, but GI irAEs were also prevalent and severe. This emphasizes a critical issue as pembrolizumab is increasingly being used in early TNBC and could have long-term survivorship implications.
Purpose: To test the generalizability of an electronic health record (EHR) phenotype for patients with advanced solid cancer, which was previously developed in a single cancer center.
Methods: We compared an algorithm to identify patients with advanced solid cancer from a random sample of patients with active cancer in the Veterans Health Administration (VA) and an academic cancer center with a human-coded reference standard between January 1, 2016, and December 31, 2019.
Results: Compared with the human-coded reference standard, the algorithm had high specificity (93%; 95% CI, 87 to 99 and 97%; 95% CI, 93 to 100) and reasonable sensitivity (85%; 95% CI, 76 to 94 and 87%; 95% CI, 77 to 97) in the VA and academic cancer center populations, respectively. Patients with advanced cancer (compared with those with active nonadvanced cancer) had higher mortality at the VA and academic cancer center (29.2% and 17.0% 6-month mortality v 6.8% and 3.5%), respectively.
Conclusion: This EHR phenotype can be used to measure and improve the quality of palliative care for patients with advanced cancer within and across health care settings.
Breast cancer during pregnancy is uncommon; however, it is one of the most common malignancies affecting pregnant women. Pregnancy-associated breast cancer (PABC) is a complex entity characterized by unique risk factors, presentation, and pathology. Furthermore, although management generally aims to mirror that for nonpregnant patients, there are distinct aspects of oncologic care delivery specific to PABC. The focus is on optimizing maternal outcomes while maximizing maternal and fetal safety. A multidisciplinary approach is key, and the timing of various treatment modalities is critical. Postdelivery care and counseling are also imperative to address issues such as contraception, breastfeeding, and future fertility. In the present review, we discuss the current knowledge base and the diagnostic and treatment landscape for PABC, including recent literature and practice pattern updates.
Purpose: Based on the International Duration Evaluation of Adjuvant Chemotherapy analysis, 3 months of adjuvant chemotherapy with capecitabine and oxaliplatin (CAPOX) is an option for stage III colorectal cancer (colorectal cancer [CRC]), with cost and toxicity benefits. We examined the patterns of uptake of CAPOX versus fluorouracil, leucovorin, and oxaliplatin (FOLFOX) and chemotherapy duration in a contemporary real-world cohort of patients in Canada.
Methods: The provincial pharmacy database was used to identify patients with resected stage III CRC receiving adjuvant chemotherapy between January 2021 and December 2022. Demographic, tumor, and treatment information was collected and compared.
Results: Of 452 patients, 234 (52%) and 218 (48%) were planned to receive 3 and 6 months of chemotherapy, respectively. Within the 3-month group, 226 (97%) received CAPOX. Within the 6-month group, there was a 51%-49% split between CAPOX and FOLFOX. Age >70 years (P = .039), well/moderately differentiated (P = .005), and low-risk disease (P < .0001) were significantly associated with 3 months. Performance status, ileostomy, or preexisting neuropathy did not affect treatment choice. Of patients planned for 6 months, 29% had low-risk disease, with 52% of these receiving CAPOX. Patients receiving 6 months were more likely to report neuropathy (68 v 36%, P < .0001) and to stop oxaliplatin early (54 v 31%, P < .0001). The most likely reason for early adjuvant discontinuation was neuropathy in the 6-month group and gastrointestinal toxicity in the 3-month group (P < .0001). Irrespective of duration, mean time from consult to starting chemotherapy was longer for FOLFOX versus CAPOX (24 v 19 days, P = .007).
Conclusion: In this contemporary cohort, 6 months chemotherapy is still being offered to patients with low-risk disease and is associated with more neuropathy. Exploration of patient preferences and resource costs may improve adoption of reduced duration adjuvant CAPOX in stage III CRC.
Purpose: International medical graduates (IMGs) are an essential component of the oncology workforce in the United States, comprising a third of all practicing oncologists and almost half of hematology/oncology fellows. In this article, we discuss the contributions of IMGs in the US oncology workforce, review unique challenges faced by IMGs, and propose potential solutions to overcome these challenges.
Methods: ASCO's IMG Community of Practice was established with the mission to connect, mentor, guide, raise awareness, and overcome the challenges unique to IMGs interested in pursuing medical oncology in the United States. The content of this article is based on discussions at the IMG Community of Practice meetings at ASCO's 2023 and 2024 Annual Meetings.
Results: IMGs bring an inherent diversity of thought and experience to the oncology workforce. They provide high-quality, culture- and language-concordant care to a diverse population of patients with cancer. However, IMGs in oncology face significant hardships throughout their careers, including visa-related restrictions, psychosocial and cultural struggles, as well as differential treatment while applying for residency and fellowship training, and early career positions. Greater awareness of these challenges among the members of the hematology/oncology community, along with institutional and individual efforts to support IMGs, is warranted.
Conclusion: We encourage oncology professionals and institutions to join our efforts in recognizing the unique paths of IMGs and providing support and advocacy to maximize the potential of IMGs in the US oncology workforce.
Purpose: In this study, we describe the geographic distribution of US cancer treatment trials to identify disparities and opportunities for targeted improvements in access to research for people with cancer.
Methods: US-based phase I-III cancer treatment trials registered on ClinicalTrials.gov were tabulated for the years they were open to enrollment (2017-2022), overall and by county, and supplemented with data from the US Census Bureau, National Cancer Institute, Centers for Disease Control and Prevention, and US Department of Agriculture. We evaluated geographic differences in trial availability. We assessed 5-year trends in trials per capita and mapped 1-hour drive time areas around sites.
Results: A total of 6,710 trials were open to enrollment in 2022 across 1,836 sites. Trials increased by 4%, whereas sites decreased by 3% annually per capita from 2017. Seventy percent of US counties had no reported active trials in 2022 (2,211/3,143), representing 19% of people age ≥55 years. Eighty-six percent of nonmetropolitan counties had no trials versus 44% of metropolitan counties. Trial availability varied by county-level cancer mortality and social vulnerability (an index derived from demographic and socioeconomic data from the US Census). Eighteen percent of counties without trials had oncologist care sites (n = 618). Notably, 26% of people age ≥55 years lived beyond an hour drive of a site with ≥100 trials.
Conclusion: Most US counties have limited to no trial offerings, a disparity magnified in counties that are nonmetropolitan, with high social vulnerability, and with high cancer mortality. Effort to facilitate diverse site participation is needed to promote equitable access to trials and to ensure patients participating in trials match the characteristics of patients who will receive interventions once approved. Counties with oncology care sites but no trials provide potential expansion areas.
As is the case with most solid tumors, the heterogeneity of the disease biology of prostate cancer presents clinicians managing this disease with daily challenges. However, in contrast to other common cancers such as breast, lung, and colorectal cancers, there are unique challenges in prostate cancer management, including the variety of clinicians who manage aspects of the disease (urologists, medical oncologist, radiation oncologists) and the striking absence of prospective comparative data to inform the optimal sequence of systemic therapy in patients with metastatic castration-resistant disease. The purpose of this review is to attempt to assist practicing oncologists with sorting through the myriad of prostate cancer disease subsets and the challenges in making therapeutic decisions in multiple data-free zones given the absence of level 1 comparative clinical trials in the metastatic hormone-sensitive and castration-resistant states.
