METHODS: This international cross-sectional study of oncology physicians in LATAM included a 43-item anonymous online survey to evaluate changes and adaptations to clinical practice. Multivariable logistic regression analyses were used to evaluate the association of caring for patients with COVID-19 and changes to clinical practice. RESULTS: A total of 704 oncology physicians from 19 countries completed the survey. Among respondents, the most common specialty was general oncology (34%) and 56% of physicians had cared for patients with COVID-19. The majority of physicians (70%) noted a decrease in the number of new patients evaluated during the COVID-19 pandemic when compared with prepandemic, and 73% reported adopting the use of telemedicine in their practice. More than half (58%) of physicians reported making changes to the treatments that they offered to patients with cancer. In adjusted models, physicians who had cared for patients with COVID-19 had higher odds of changing the type of chemotherapy or treatments that they offered (adjusted odds ratio 1.81; 95% CI, 1.30 to 2.53) and of delaying chemotherapy start (adjusted odds ratio 2.05; 95% CI, 1.49 to 2.81). Physicians identified significant delays in access to radiation and surgical services, diagnostic tests, and supportive care. CONCLUSION: The COVID-19 pandemic has significantly disrupted global cancer care. Although changes to health care delivery are a necessary response to this global crisis, our study highlights the significant disruption and changes to the treatment plans of patients with cancer in LATAM resulting from the COVID-19 health care crisis. In late 2019, COVID-19, a disease caused by severe acute respiratory coronavirus 2, emerged across the world, leading to a global pandemic with more than 173 million cases and 3.7 million deaths as of June 2021. 1 COVID-19 has disrupted health care globally, overwhelming health care systems, halting nonemergent medical procedures, and leading to scarcity of medical resources. [2] [3] [4] Reports from the United States and Europe show that COVID-19 has led to an alarming decline in cancer screening, delayed diagnostic tests, and treatment modifications, which might have longstanding effects on cancer outcomes. [5] [6] [7] [8] As a result, national and international societies have published guidelines and recommendations to prioritize and adapt the care of patients with cancer during COVID-19. [9] [10] [11] However, changes in physician practice patterns and cancer care in limited-resource settings, such as Latin America (LATAM), have not been thoroughly reported. Studying the impact of COVID-19 on cancer in LATAM is of utmost importance since two of the countries with the highest number of COVID-19 deaths, Brazil and Mexico, are located in the region. 1 The International Agency for Research on Cancer estimated more than 1.4 million new cancer cases in LATAM for 2020, 12 a number projected to increase to more than1.7 million new cases per year by 2030. [13] [14] [15] Patients with cancer in LATAM face numerous barriers for obtaining adequate medical care because of limited resources and fragmented systems that have been disproportionally affected by COVID-19. Given the expected growth in cancer burden in LATAM, we must understand how cancer care in the region has changed during these unprecedented times. Therefore, we sought to evaluate the impact of COVID-19 on oncology practices across LATAM, by assessing the challenges faced by physicians in diagnosing and treating cancer and the clinical practice modifications that they adopted during the pandemic. This cross-sectional study was led by a group of researchers from LATAM and the United States. LATAM is a region consisting of 20 countries and 14 territories stretching from Mexico to Tierra del Fuego (Chile and Argentina) and including the Caribbean (Cuba, Dominican Republic, and Puerto Rico). The HOLA COVID-19 study included oncology physicians practicing in LATAM. We identified local leaders from each country using social media and the ASCO membership directory. An electronic invitation was distributed to physicians from LATAM countries to become study ambassadors. Using snowball sampling, each ambassador recruited participants via a multimodal approach, which included social media, e-mail invitations, professional society directories and mailing lists, and other local physician communication networks. Ambassadors distributed the online survey via a personal link using the SurveyMonkey platform (SurveyMonkey, San Mateo, CA) during August 4-24, 2020. The target population was physicians specialized in hematology and/or oncology, surgical oncology, radiation oncology, or gynecologic oncology. All recruitment efforts and communications were available in Spanish, Portuguese, and English. The survey consisted of 43 questions designed by the research team, who are native bilingual Spanish/English We used binary multivariable logistic regression to evaluate the association of caring for patients with COVID-19 with the primary outcome of change in clinical practice (on the basis of the survey question "Have you changed the type of chemotherapy or treatment that you offer to your cancer patients during the months of February-June 2020?" Yes/ No). On the basis of expert input and significance on univariate regression (not shown), multivariable models were adjusted for physician specialty and age (used as surrogate for years in practice). Secondary exploratory outcomes included change to a less effective regimen with fewer complications or side effects, discontinuation of chemotherapy, and delay of chemotherapy start. We To evaluate the impact of COVID-19 on oncology practices across Latin America. Knowledge Generated Physicians who cared for patients with COVID-19 were more likely to change the chemotherapy regimens that they offered to patients with cancer, to discontinue palliative chemotherapy, and to cancel or delay concurrent chemoradiation. Relevance There were significant disruptions in cancer care delivery, which can worsen outcomes across Latin America in the upcoming years. Our data may serve as a guide to build strategies to rebuild cancer care in the region. performed generalized ordinal logistic regression 16, 17 to explore the association of our secondary outcomes with caring for patients with COVID-19; respondents who selected not applicable were excluded. We used marginal effects to estimate the probability of each secondary outcome. Statistical significance was assumed at a P value , .05. Data were analyzed using Stata version 16 (StataCorp LLC, College Station, TX). Between August 4 and 24, 2020, 913 oncology physicians initiated the survey, of which 704 (77%) completed the survey and were included in the analysis (Fig 1) . Respondents originated from 19 LATAM countries, with the highest number practicing in Mexico (29%, n = 205), Brazil (11%, n = 76), and Chile (9%, n = 61). Most physicians were men (57%, n = 402), 31-40 years old (40%, n = 284), and practiced medical oncology (34%, n = 239). Table 1 shows physician demographics and workplace characteristics. Among respondents, 266 (38%) worked in a practice with more than 10 providers and more than half (58%, n = 410) worked full time. The most common practice settings were private clinics (58%, n = 405), state hospitals (43%, n = 304), and academic/university hospitals (40%, n = 280). At the time of the survey, 56% of physicians had cared for patients with COVID-19 (n = 397). Physicians noted that Currently not working Impact of COVID-19 on Cancer Care in Latin America most of their practices (85%, n = 574) implemented screening questionnaires for COVID-19 symptoms prechemotherapy. Notably, 29% (n = 201) of physicians reported that their practice had implemented COVID-19 testing for all patients before initiating chemotherapy, whereas 32% (n = 228) implemented testing only for symptomatic patients, and 28% (n = 200) had no pre-=chemotherapy testing. Most physicians (70%, n = 491) noted a decrease in the number of new patients evaluated during the pandemic when compared with before COVID-19 (pre-February 2020). The proportion of physicians who reported seeing less than five new patients per day increased from 40% (n = 279) before the pandemic to 73% (n = 513) during the pandemic (P , .001). Most physicians (72%, n = 505) reported fewer follow-up visits when compared with pre-COVID-19. As shown in Table 2 , physicians cared for patients in various settings, including hospitals, outpatient clinics, and telemedicine. Telemedicine was adopted broadly, with 73% (n = 512) of physicians using telemedicine in their oncology practice at the time of the survey, compared with only 14% (n = 98) before COVID-19 (P , .001). Physicians who cared for patients with COVID-19 were more likely to see patients in hospital settings than those who did not (67 v 58%; P = .019). Oncology physicians reported significant changes in access to diagnostic resources (Fig 2) . Eleven percent (n = 77) reported having no access to positron emission tomography-computed tomography (CT) or CT during the pandemic, and 59% (n = 413) noted that the availability of these diagnostic tests decreased somehow or significantly. Lower access to CT and positron emission tomography-CT was reported more frequently by physicians who cared for patients with COVID-19 than those who did not (P = .001). Similar differences were noted in access to biopsies, supportive medications (ie, antiemetics and growth If you are using telemedicine, how much time passed from the closing of your practice to the implementation of telemedicine? Used telemedicine before the pandemic 73 (10) 31 (8) 42 (14) Days to 1 week 150 (21) 86 (22) 64 (21) 2-3 weeks 122 (17) 73 (19) 49 (16) 1 month or more 160 (23) 101 (26) 59 (19) We do not use telemedicine 194 (28) 103 (26) 91 (30) factors), and social work and supportive care staff. Most physicians had access to COVID-19 testing for their patients (72%, n = 504). In a minority of cases, COVID-19 testing was limited to patients who could pay out-of-pocket costs (9%, n = 64). Physicians also noted delays in access to specialty care. Most (65%, n = 456) reported delays in referrals to surgical oncology, irrespective of whether they took care of patients with COVID-19 (P = .051). However, 78% (n = 544) reported that their patients were evaluated by a surgical oncologist within 30 days of referral. Most physicians reported that cancer surgeries had been delayed (61%, n = 429), and 20% (n = 141) noted that surgeries had been canceled; 20% (n = 138) reported surgeries had been delayed for over a month. Regarding access to radiotherapy, that 49% (n = 343) of physicians reported delays in time to evaluation. Physicians who cared for patients with COVID-19 were more likely to report delays in radiotherapy assessments than those who did not care for patients with COVID-19 (55 v 44%; P = .004). Most physicians reported that their patients were evaluated by radiation oncology within 30 days of referral (73%, n = 515). Oncology physicians noted significant changes in their clinical practice (ie, patient management), with 58% (n = 404) reporting that they had changed the type of chemotherapy or treatments they offered to patients, 47% (n = 330) reporting that they held or delayed chemotherapy because of the pandemic, and 38% (n = 269) had delayed or canceled adjuvant chemotherapy. Significant differences were observed in the proportion of physicians who delayed or held chemotherapy for ≥ 8 days between those who took care of patients with COVID-19 and those who did not (48 v 31%; P = .001). As shown in Figure 3 , there are variability and differences in the frequency of self-reported changes to patient management between physicians who cared for patients with COVID-19 and those who did not. For example, physicians who cared for patients with COVID-19 were more likely to change chemotherapy regimens to decrease potential adverse events than physicians who did not care for patients with COVID-19 (57 v 46% changed chemotherapy in some, most, or all cases; P = .006). Similarly, physicians who cared for patients with COVID-19 were more likely to discontinue palliative chemotherapy (49 v 38% discontinued palliative chemotherapy in some, most, or all cases; P = .011) and to cancel or delay concurrent chemoradiation (42 v 31% in some, most, or all cases; P = .007). Overall, physicians reported increasing the use of oral chemotherapy and supportive care medications. Multivariable logistic regression models evaluated the association of caring for patients with COVID-19 and key changes to clinical practice. As shown in Table 3 , after adjusting for age and specialty, physicians who cared for patients with COVID-19 had higher odds of changing the type of chemotherapy or treatments offered to their patients (adjusted odds ratio 1.81; 95% CI, 1.30 to 2.53). We observed significant differences in self-reported changes of type of chemotherapy among specialties, with hematologists Impact of COVID-19 on Cancer Care in Latin America and surgical specialists (surgical oncologists and gynecologic oncologists) having lower odds of changing chemotherapy. Older physician age was associated with lower odds of changing chemotherapy in the adjusted model. In Table 4 , ordinal regression models explore the associations of caring for patients with COVID-19 and secondary outcomes of interest. Physicians who cared for patients with COVID-19 tended to have higher odds of reporting that they had stopped chemotherapy in patients previously on treatment and delayed chemotherapy starts. As shown in Figure 4 , the probability of reporting having stopped or delayed chemotherapy in some or most/all cases was highest among those who cared for patients with COVID-19. The results of HOLA COVID-19 highlight the impact of the COVID-19 pandemic on oncology practices across LATAM. Among a large sample of oncology physicians, we found that a significant proportion directly participated in the care of patients with COVID-19. Interestingly, physicians who took care of patients with COVID-19 were more likely to change their patterns of cancer care and to modify treatments than those who did not. In addition, most physicians adapted Respondents (%) their clinical practice to provide care for patients via telemedicine, demonstrating that this strategy might be useful in resource-limited settings like LATAM. Worryingly, most participants reported seeing a significantly lower volume of new patients and follow-up visits during the pandemic. Patients with cancer have a significantly higher risk of acquiring COVID-19 and worse outcomes, including increased mortality and severe illness requiring intensive care unit admission. 18, 19 Within this vulnerable group, older age, belonging to socially disadvantaged populations (eg, racial/ethnic minorities and people living in poverty), having poor performance status, and having active cancer are associated with worse outcomes, specifically increased mortality. 19, 20 The vulnerability of patients with cancer to COVID-19, compounded with overwhelmed health care systems, has led oncologists to make modifications to their practices on a case-by-case basis, hoping to minimize the risk of exposing patients with cancer to COVID-19. In our study, we observed important modifications in practice patterns, with more than half of the respondents reporting changing treatment regimens offered to patients. Changes in intensity and length of therapy were used to avoid potential adverse events and to decrease patient contact with health care settings, limiting potential exposures to COVID-19. Although in some cases, modifying, omitting, delaying, or shortening treatment regimens may be appropriate, in others, this might have deleterious impacts on survival or quality of life. 21 Although we did not assess the specific changes in chemotherapy dosing or schedules made by oncology physicians in response to the pandemic, the fact that more than a third delayed or canceled adjuvant treatments shows that potentially curative treatments were interrupted, which could affect cancer outcomes in the region. This is also supported by the delays in surgical interventions and/or radiotherapy. Overall, our results provide evidence to the extent to which the global COVID-19 pandemic has created new challenges and amplified pre-existing barriers to the diagnosis, treatment, and supportive care of patients with cancer in LATAM. Our study uniquely builds on previously published data showing changes and delays to cancer care across the world. In response to the COVID-19 pandemic, cancer centers have adopted restrictive visitation policies, mandated the use of personal protective equipment, implemented telemedicine, and separated patients with COVID-19 via established pathways. 22 Survey studies of providers from cancer centers around the world reported significant alterations to care, with 44% of oncologic surgeries, 25% of chemotherapy sessions, and 14% of radiotherapy appointments being canceled or delayed. 23 Medical oncologists reported using less intravenous agents, such as chemotherapy and immunotherapy, and the majority were less likely to recommend second-or third-line therapies to patients with metastatic disease. 24 During the pandemic, oncologists considered factors such as patient's age, performance status, and comorbidities when choosing cancer-directed therapies. 24 Internationally, more than half Age groups 21-30 and 31-40 were collapsed into one group, and groups 61-70 and . 70 were also collapsed into one group because of the sample size. Surgical and gynecologic oncology specialties collapsed because of the small sample size. Impact of COVID-19 on Cancer Care in Latin America of cancer centers had reduced assistance for patients, which not only affected treatment but also led to reduced appointments with support care staff, such as psychologists, nutritionists, social workers, and educators. 25 Our findings highlight that changes and delays in therapy and decreased access to diagnostics and supportive and specialty care are heightened by physicians' direct experience of caring for patients with COVID-19. This finding may reflect physician responses to their personal experience witnessing the effects of COVID-19 in ill patients and/ or their response to working in overwhelmed health care systems. Besides our study, little is known about the impact of COVID-19 on LATAM oncology practices. Data from LATAM radiation oncology practices showed that 80% of the practices described a reduction in patient volume. 26 A survey of breast cancer specialists from LATAM countries reported that 42% of respondents worked in hospitals that were brought to a standstill during the pandemic. 27 Similarly, an online survey of LATAM pediatric hematologist- , (B) Self-reported frequency to changes to clinical practice when asked "Please choose the proportion of your practice that has been affected by the following changes since March 2020 compared to last year." Among the proposed options, the most clinically relevant are shown: (A) change to a less effective regimen, but with fewer complications or side effects, (B) stop giving chemotherapy to the patients who were already on treatment, and (C) delay the start of chemotherapy. Reported frequencies are based on Likert scale options: in all cases, in most cases, in some cases, in the minority of cases, no changes, and not applicable. Because of the small sample size across categories, in all cases and most cases were collapsed into one category. Respondents who selected not applicable are excluded. oncologists found that although ongoing chemotherapies were maintained, a significant proportion of outpatient procedures, surgeries, radiotherapy, and stem-cell transplantations were delayed indefinitely. 28 Furthermore, 60% of respondents reported a significant decrease in workforce availability because of COVID-19 infection or quarantine. 28 Understanding the effects of COVID-19 on cancer care in developing regions of the world, where access to health care is limited, is essential to prepare both for the postpandemic recovery period and for future epidemic events. According to the United Nations Economic Commission for LATAM and the Caribbean, LATAM is the world region with highest income inequality, even prepandemic. 29, 30 These economic challenges are expected to worsen during the pandemic, leading to an increase in poverty, political instability, and long-lasting effects on the care of chronic diseases, such as cancer. 31, 32 Strengths of HOLA COVID-19 include a large sample size with respondents from most LATAM countries, a multimodal recruitment approach, and the fact that, since the link was privately shared, the survey was likely only answered by oncology physicians. Limitations of our study include its cross-sectional nature, which allows us to capture data at a single timepoint and makes us unable to establish longitudinal relationships between exposure and outcomes. In addition, as there is no centralized governing body that guides oncology care and education in LATAM, the total number of oncologists in the region is unknown. Given this limitation, we used snowball sampling via a multimodal approach to increase our recruitment reach. Snowball sampling inherently introduces limitations and bias, which include the inability to estimate the number of individuals reached, unknown probability of selection, which can limit generalizability, and differential recruitment as evidenced by the small number of participants from Brazil when compared with Mexico. Other weaknesses include potential selection bias since physicians who were affected the most by COVID-19 could have been more inclined to answer the survey. However, the fact that almost half of respondents had not directly cared for patients with COVID-19 shows that this might not be the case. In addition, since our recruitment was primarily performed electronically, most participants were young physicians. Finally, we did not capture changes in treatment on a case-by-case basis, and therefore, we cannot say whether modifications led to undertreatment and/or worse outcomes. Despite these limitations, we believe that our findings provide a thorough overview of practice changes in the region and reflect the challenges experienced by LATAM oncologists during COVID-19. During the past year, COVID-19 has affected the care of patients with cancer and oncologic practices throughout the world. Our study provides evidence of the impact and effects of the pandemic on oncology practices in LATAM, where health care systems are fragmented and access to cancer care is limited. Although the reported practice changes may seem like a reasonable response to the health care crisis created by the pandemic, significant disruptions in cancer care delivery and worsening outcomes across the regions could occur in the coming years. We hope that our data can serve as a guide to develop strategies focused on rebuilding cancer care in LATAM and avoiding disruptions during future health care crises.
