Anti-Interleukin-23 Autoantibodies in Adult-Onset Immunodeficiency.

BACKGROUND: Autoantibodies against interleukin-12 (anti-interleukin-12) are often identified in patients with thymoma, but opportunistic infections develop in only some of these patients. Interleukin-12 (with subunits p40 and p35) shares a common subunit with interleukin-23 (subunits p40 and p19). In a patient with disseminated Burkholderia gladioli infection, the identification of both anti-interleukin-23 and anti-interleukin-12 prompted further investigation. METHODS: Among the patients (most of whom had thymoma) who were known to have anti-interleukin-12, we screened for autoantibodies against interleukin-23 (anti-interleukin-23). To validate the potential role of anti-interleukin-23 with respect to opportunistic infection, we tested a second cohort of patients with thymoma as well as patients without either thymoma or known anti-interleukin-12 who had unusual infections. RESULTS: Among 30 patients with anti-interleukin-12 who had severe mycobacterial, bacterial, or fungal infections, 15 (50%) also had autoantibodies that neutralized interleukin-23. The potency of such neutralization was correlated with the severity of these infections. The neutralizing activity of anti-interleukin-12 alone was not associated with infection. In the validation cohort of 91 patients with thymoma, the presence of anti-interleukin-23 was associated with infection status in 74 patients (81%). Overall, neutralizing anti-interleukin-23 was detected in 30 of 116 patients (26%) with thymoma and in 30 of 36 patients (83%) with disseminated, cerebral, or pulmonary infections. Anti-interleukin-23 was present in 6 of 32 patients (19%) with severe intracellular infections and in 2 of 16 patients (12%) with unusual intracranial infections, including Cladophialophora bantiana and Mycobacterium avium complex. CONCLUSIONS: Among patients with a variety of mycobacterial, bacterial, or fungal infections, the presence of neutralizing anti-interleukin-23 was associated with severe, persistent opportunistic infections.

Breast Health Awareness: Understanding Health-Seeking Behavior in Western Kenya.

INTRODUCTION: In Kenya, patients with breast cancer predominantly present with late-stage disease and experience poor outcomes. To promote early-stage diagnosis, we implemented the Academic Model Providing Access to Healthcare (AMPATH) Breast and Cervical Cancer Control Program (ABCCCP) in Western Kenya. OBJECTIVE: The aim of this study was to assess differences between patients presenting to health facilities and health fairs. METHODS: This was an institutional Review and Ethics Commitee-approved retrospective cohort study of all individuals who underwent clinical breast examination (CBE) via local healthcare workers in Western Kenya. From 2017 to 2021, the program hosted health fairs, and trained healthcare providers at health facilities to complete CBEs. Results were analyzed using the Chi-square and Kruskal-Wallis tests, with an α < 0.05. RESULTS: Over a 5-year period, the ABCCCP completed 61,812 CBEs with 75.9% (n = 46,902) performed at a health facility. Patients presenting to health fairs were older (44 vs. 38 years; p < 0.0001) and had higher risk factor rates including early menarche, family history of breast and ovarian cancer, and use of alcohol or smoking. Only 27.6% of patients with an abnormal CBE underwent core needle biopsy, and only 5.2% underwent repeat CBE over the 5-year period, of whom 90.3% presented to health facilities. CONCLUSIONS: Successful uptake of CBE through the ABCCCP is the first step to introduce breast health awareness (BHA). Benefits of broad advertisements for health fairs in promoting BHA may be limited to a single event. Poor rates of repeat examinations and diagnostic testing of abnormal CBEs indicate additional resources should be allocated to educating patients, including about possible treatment trajectories for breast cancer.

Global oncology research and training at US National Cancer Institute-designated cancer centres: results of the 2021 Global Oncology Survey.

Global oncology research and training are crucial to address the growing global burden of cancer, which largely and increasingly occurs in low-income and middle-income countries. To better understand global oncology activities at the 71 National Cancer Institute (NCI)-designated cancer centres, the US NCI Centre for Global Health regularly surveys cancer centre directors, global oncology leads, and principal investigators in 36 US states and the District of Columbia. The survey results complement internal and publicly available data about global oncology research funded directly by the US National Institutes of Health to provide a comprehensive catalogue of global oncology research, training, and activities led by NCI-designated cancer centres. 91% (61 of 67) of responding cancer centres reported global oncology activities not directly funded by the National Institutes of Health. The survey results indicate that global oncology is an important priority at cancer centres and provide a valuable resource for these centres, researchers, collaborators, trainees, and the NCI and other funders.

Understanding the landscape of immunotherapy in thymic epithelial tumors.

Thymic epithelial tumors (TETs) are a rare group of malignancies arising from the thymus. Surgery remains the foundation of treatment for patients with early-stage disease. Limited treatment options are available for the treatment of unresectable, metastatic, or recurrent TETs and are associated with modest clinical efficacy. The emergence of immunotherapies in the treatment of solid tumors has generated significant interest in understanding their role in TET treatment. However, the high rates of comorbid paraneoplastic autoimmune disorders, particularly in thymoma, have tempered expectations regarding the role of immune-based therapies. Clinical studies of immune checkpoint blockade (ICB) in thymoma and thymic carcinoma have revealed higher frequencies of immune-related adverse events (IRAEs) and limited efficacy. Despite these setbacks, the growing understanding of the thymic tumor microenvironment and systemic immune system has advanced the understanding of these diseases and provided opportunities for novel immunotherapy modalities. Ongoing studies are evaluating numerous immune-based treatments in TETs with the goal of improving clinical efficacy and mitigating IRAE risk. This review will provide insight into the current understanding of the thymic immune microenvironment, outcomes of previous ICB studies, and review treatments currently being explored for the management of TET.

Association of plasma aflatoxin with persistent detection of oncogenic human papillomaviruses in cervical samples from Kenyan women enrolled in a longitudinal study.

BACKGROUND: Cervical cancer is caused by oncogenic human papillomaviruses (HR-HPV) and is common among Kenyan women. Identification of factors that increase HR-HPV persistence is critically important. Kenyan women exposed to aflatoxin have an increased risk of HR-HPV detection in cervical specimens. This analysis was performed to examine associations between aflatoxin and HR-HPV persistence. METHODS: Kenyan women were enrolled in a prospective study. The analytical cohort for this analysis included 67 HIV-uninfected women (mean age 34 years) who completed at least two of three annual study visits and had an available blood sample. Plasma aflatoxin was detected using ultra-high pressure liquid chromatography (UHPLC)-isotope dilution mass spectrometry. Annual cervical swabs were tested for HPV (Roche Linear Array). Ordinal logistic regression models were fitted to examine associations of aflatoxin and HPV persistence. RESULTS: Aflatoxin was detected in 59.7% of women and was associated with higher risk of persistent detection of any HPV type (OR = 3.03, 95%CI = 1.08-8.55, P = 0.036), HR-HPV types (OR = 3.63, 95%CI = 1.30-10.13, P = 0.014), and HR-HPV types not included in the 9-valent HPV vaccine (OR = 4.46, 95%CI = 1.13-17.58, P = 0.032). CONCLUSIONS: Aflatoxin detection was associated with increased risk of HR-HPV persistence in Kenyan women. Further studies, including mechanistic studies are needed to determine if aflatoxin synergistically interacts with HR-HPV to increase cervical cancer risk.

Joint-Predominant Rheumatic Complications of Immune Checkpoint Inhibitor Therapy in Patients with Thymic Epithelial Tumors.

Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of advanced cancers. However, activation of the immune system can occasionally cause life-threatening toxicity involving critical organs. Induction of immune-mediated toxicity is a significant concern for patients with thymic epithelial tumors (TETs) due to defects in immune tolerance. An increased risk of skeletal and cardiac muscle inflammation following treatment with ICIs is well recognized in patients with advanced TETs. However, uncommon musculoskeletal and rheumatic complications can also occur. The cases presented in this report highlight the spectrum of presentation of immune-mediated, joint-predominant musculoskeletal adverse events in patients with advanced TETs treated with ICIs, including polymyalgia rheumatica-like illness and inflammatory arthritis.

Acceptance and commitment therapy for patient fatigue interference and caregiver burden in advanced gastrointestinal cancer: Results of a pilot randomized trial.

BACKGROUND: Fatigue often interferes with functioning in patients with advanced cancer, resulting in increased family caregiver burden. Acceptance and commitment therapy, a promising intervention for cancer-related suffering, has rarely been applied to dyads coping with advanced cancer. AIM: To examine the feasibility, acceptability, and preliminary efficacy of acceptance and commitment therapy for patient-caregiver dyads coping with advanced gastrointestinal cancer. Primary outcomes were patient fatigue interference and caregiver burden. DESIGN: In this pilot trial, dyads were randomized to six weekly sessions of telephone-delivered acceptance and commitment therapy or education/support, an attention control. Outcomes were assessed at baseline and at 2 weeks and 3 months post-intervention. SETTING/PARTICIPANTS: Forty patients with stage III-IV gastrointestinal cancer and fatigue interference and family caregivers with burden or distress were recruited from two oncology clinics and randomized. RESULTS: The eligibility screening rate (54%) and retention rate (81% at 2 weeks post-intervention) demonstrated feasibility. At 2 weeks post-intervention, acceptance and commitment therapy participants reported high intervention helpfulness (mean = 4.25/5.00). Group differences in outcomes were not statistically significant. However, when examining within-group change, acceptance and commitment therapy patients showed moderate decline in fatigue interference at both follow-ups, whereas education/support patients did not show improvement at either follow-up. Acceptance and commitment therapy caregivers showed medium decline in burden at 2 weeks that was not sustained at 3 months, whereas education/support caregivers showed little change in burden. CONCLUSIONS: Acceptance and commitment therapy showed strong feasibility, acceptability, and promise and warrants further testing. TRIAL REGISTRATION: ClinicalTrials.gov NCT04010227.

Status of Cancer Care at Network Sites of the Nation's Academic Cancer Centers.

BACKGROUND: Cancer care coordination across major academic medical centers and their networks is evolving rapidly, but the spectrum of organizational efforts has not been described. We conducted a mixed-methods survey of leading cancer centers and their networks to document care coordination and identify opportunities to improve geographically dispersed care. METHODS: A mixed-methods survey was sent to 91 cancer centers in the United States and Canada. We analyzed the number and locations of network sites; access to electronic medical records (EMRs); clinical research support and participation at networks; use of patient navigators, care paths, and quality measures; and physician workforce. Responses were collected via Qualtrics software between September 2017 and December 2018. RESULTS: Of the 69 responding cancer centers, 74% were NCI-designated. Eighty-seven percent of respondents were part of a matrix health system, and 13% were freestanding. Fifty-six reported having network sites. Forty-three respondents use navigators for disease-specific populations, and 24 use them for all patients. Thirty-five respondents use ≥1 types of care path. Fifty-seven percent of networks had complete, integrated access to their main center's EMRs. Thirty-nine respondents said the main center provides funding for clinical research at networks, with 22 reporting the main center provides all funding. Thirty-five said the main center provided pharmacy support at the networks, with 15 indicating the main center provides 100% pharmacy support. Certification program participation varied extensively across networks. CONCLUSIONS: The data show academic cancer centers have extensive involvement in network cancer care, often extending into rural communities. Coordinating care through improved clinical trial access and greater use of patient navigation, care paths, coordinated EMRs, and quality measures is likely to improve patient outcomes. Although it is premature to draw firm conclusions, the survey results are appropriate for mapping next steps and data queries.

A large microRNA cluster on chromosome 19 is a transcriptional hallmark of WHO type A and AB thymomas.

BACKGROUND: Thymomas are one of the most rarely diagnosed malignancies. To better understand its biology and to identify therapeutic targets, we performed next-generation RNA sequencing. METHODS: The RNA was sequenced from 13 thymic malignancies and 3 normal thymus glands. Validation of microRNA expression was performed on a separate set of 35 thymic malignancies. For cell-based studies, a thymoma cell line was used. RESULTS: Hierarchical clustering revealed 100% concordance between gene expression clusters and WHO subtype. A substantial differentiator was a large microRNA cluster on chr19q13.42 that was significantly overexpressed in all A and AB tumours and whose expression was virtually absent in the other thymomas and normal tissues. Overexpression of this microRNA cluster activates the PI3K/AKT/mTOR pathway. Treatment of a thymoma AB cell line with a panel of PI3K/AKT/mTOR inhibitors resulted in marked reduction of cell viability. CONCLUSIONS: A large microRNA cluster on chr19q13.42 is a transcriptional hallmark of type A and AB thymomas. Furthermore, this cluster activates the PI3K pathway, suggesting the possible exploration of PI3K inhibitors in patients with these subtypes of tumour. This work has led to the initiation of a phase II clinical trial of PI3K inhibition in relapsed or refractory thymomas (http://clinicaltrials.gov/ct2/show/NCT02220855).

Phase I Study of Lenalidomide and Sorafenib in Patients With Advanced Hepatocellular Carcinoma.

LESSONS LEARNED: Combination therapies in patients with hepatocellular carcinoma can be associated with overlapping toxicity and are therefore poorly tolerated.Using sorafenib at the maximum tolerated dose can lead to a higher incidence of toxicities. Consequently, combination studies might evaluate sorafenib at alternative schedules or doses to improve tolerance, recognizing this could affect sorafenib efficacy.Although this combination was poorly tolerated, it does not exclude further evaluation of new-generation immunomodulator drugs or immune checkpoint inhibitors in the hope of optimizing tolerance and safety. BACKGROUND: Sorafenib is the standard treatment for advanced hepatocellular carcinoma (HCC), and to date, no combination therapy has demonstrated superior survival compared with sorafenib alone. The immunosuppressive microenvironment in HCC is a negative predictor for survival. Lenalidomide is an immunomodulator and antiangiogenic agent, with limited single-agent efficacy in HCC. Based on these data, we designed a phase I study of sorafenib plus lenalidomide to determine the safety and preliminary antitumor activity of this combination. METHODS: This was an open-label, phase I study with a 3+3 dose escalation/de-escalation design. The starting dose of sorafenib was 400 mg p.o. b.i.d. and of lenalidomide was 15 mg p.o. daily with a planned dose escalation by 5 mg per cohort up to 25 mg daily. Dose de-escalation was planned to a sorafenib dose of 400 mg p.o. daily combined with two doses of lenalidomide: 10 mg p.o. daily for a 28-day cycle (cohort 1) and 10 mg p.o. daily for a 21- or 28-day cycle (cohort 2). Patients with cirrhosis, a Child-Pugh score of A-B7, and no previous systemic therapy were eligible. RESULTS: Five patients were enrolled. Their median age was 56 years (range 39-61), and the ECOG status was 0-2. Four patients were treated at dose level (DL) 1. Because of the poor tolerance to the combination associated with grade 2 toxicities, one more patient was treated at DL -1. No dose-limiting toxicity was observed as specified per protocol. The most common toxicities were nausea, anorexia, pruritus, elevated liver enzymes, and elevated bilirubin. Three patients experienced one or more of the following grade 3 toxicities: fatigue (DL 1), increased bilirubin (DL 1), skin desquamation (DL -1), and elevated transaminase levels (DL 1). The median duration of therapy was 1 cycle (range 1-3). All patients discontinued the study, 4 because of progressive disease and 1 by patient preference. The best confirmed response was progressive disease. The median progression-free survival was 1.0 month (95% confidence interval 0.9-2.8), and the median overall survival was 5.9 months (95% confidence interval 3.68-23.4). CONCLUSION: In our small study, the combination of lenalidomide and sorafenib was poorly tolerated and showed no clinical activity. Although the study was closed early because of toxicity concerns, future studies assessing combinations of sorafenib with new-generation immunomodulator drugs or other immunomodulatory agents, should consider lower starting doses of sorafenib to avoid excessive toxicity.

Sunitinib in patients with chemotherapy-refractory thymoma and thymic carcinoma: an open-label phase 2 trial.

BACKGROUND: No standard treatments are available for advanced thymic epithelial tumours after failure of platinum-based chemotherapy. We investigated the activity of sunitinib, an orally administered tyrosine kinase inhibitor. METHODS: Between May 15, 2012, and Oct 2, 2013, we did an open-label phase 2 trial in patients with histologically confirmed chemotherapy-refractory thymic epithelial tumours. Patients were eligible if they had disease progression after at least one previous regimen of platinum-containing chemotherapy, an Eastern Cooperative Oncology Group performance status of two or lower, measurable disease, and adequate organ function. Patients received 50 mg of sunitinib orally once a day, in 6-week cycles (ie, 4 weeks of treatment followed by 2 weeks without treatment), until tumour progression or unacceptable toxic effects arose. The primary endpoint was investigator-assessed best tumour response at any point, which we analysed separately in thymoma and thymic carcinoma cohorts. Patients who had received at least one cycle of treatment and had their disease reassessed were included in the analyses of response. The trial was registered with ClinicalTrials.gov, number NCT01621568. FINDINGS: 41 patients were enrolled, 25 with thymic carcinoma and 16 with thymoma. One patient with thymic carcinoma was deemed ineligible after enrolment and did not receive protocol treatment. Of patients who received treatment, one individual with thymic carcinoma was not assessable because she died. Median follow-up on trial was 17 months (IQR 14.0-18.4). Of 23 assessable patients with thymic carcinoma, six (26%, 90% CI 12.1-45.3, 95% CI 10.2-48.4) had partial responses, 15 (65%, 95% CI 42.7-83.6) achieved stable disease, and two (9%, 1.1-28.0) had progressive disease. Of 16 patients with thymoma, one (6%, 95% CI 0.2-30.2) had a partial response, 12 (75%, 47.6-92.7) had stable disease, and three (19%, 4.1-45.7) had progressive disease. The most common grade 3 and 4 treatment-related adverse events were lymphocytopenia (eight [20%] of 40 patients), fatigue (eight [20%]), and oral mucositis (eight [20%]). Five (13%) patients had decreases in left-ventricular ejection fraction, of which three (8%) were grade 3 events. Three (8%) patients died during treatment, including one individual who died of cardiac arrest that was possibly treatment-related. INTERPRETATION: Sunitinib is active in previously treated patients with thymic carcinoma. Further studies are needed to identify potential biomarkers of activity.

Exploring Metabolic Profile Differences between Colorectal Polyp Patients and Controls Using Seemingly Unrelated Regression.

Despite the fact that colorectal cancer (CRC) is one of the most prevalent and deadly cancers in the world, the development of improved and robust biomarkers to enable screening, surveillance, and therapy monitoring of CRC continues to be evasive. In particular, patients with colon polyps are at higher risk of developing colon cancer; however, noninvasive methods to identify these patients suffer from poor performance. In consideration of the challenges involved in identifying metabolite biomarkers in individuals with high risk for colon cancer, we have investigated NMR-based metabolite profiling in combination with numerous demographic parameters to investigate the ability of serum metabolites to differentiate polyp patients from healthy subjects. We also investigated the effect of disease risk on different groups of biologically related metabolites. A powerful statistical approach, seemingly unrelated regression (SUR), was used to model the correlated levels of metabolites in the same biological group. The metabolites were found to be significantly affected by demographic covariates such as gender, BMI, BMI(2), and smoking status. After accounting for the effects of the confounding factors, we then investigated potential of metabolites from serum to differentiate patients with polyps and age matched healthy controls. Our results showed that while only valine was slightly associated, individually, with polyp patients, a number of biologically related groups of metabolites were significantly associated with polyps. These results may explain some of the challenges and promise a novel avenue for future metabolite profiling methodologies.

Micronodular thymic neoplasms: case series and literature review with emphasis on the spectrum of differentiation.

We report nine cases of micronodular thymoma with lymphoid B-cell hyperplasia and one case of micronodular thymic carcinoma with lymphoid hyperplasia from our institution. For a better understanding of these rare tumors, clinical records, and histological features of these cases were reviewed, with detailed review of additional 64 literature cases of micronodular thymic neoplasms. The joint analysis identified 64 cases of micronodular thymoma with lymphoid B-cell hyperplasia and 9 cases of micronodular thymic carcinoma with lymphoid hyperplasia. Both groups revealed slight male predilection, with male:female ratio of 1.3:1 and 5:4, and occurred at >40 years of age, with a mean of 64 (41-83) and 62 (42-78) years, respectively. Myasthenia gravis was noted in 3/64 (5%) and 1/9 (11%) patients, respectively. Other systemic, disimmune, or hematologic disorders were noted in 6/64 (9%) and 1/9 (11%) patients, respectively. Components of conventional thymoma were reported in 11/64 (17%) micronodular thymomas with lymphoid B-cell hyperplasia, with transitional morphology between the two components in most of them. Cellular morphology was predominantly spindle in micronodular thymoma with lymphoid B-cell hyperplasia when specified (30/43), and epithelioid in micronodular thymic carcinoma with lymphoid hyperplasia (6/9), and cytological atypia was more encountered in the latter. Dedifferentiation/transformation from micronodular thymoma with lymphoid B-cell hyperplasia to micronodular thymic carcinoma with lymphoid hyperplasia seems to occur in a small subset of cases. Three cases of micronodular thymomas with lymphoid B-cell hyperplasia were described with co-existent low-grade B-cell lymphomas. Follow-up data were available for 30 micronodular thymomas with lymphoid B-cell hyperplasia and 6 micronodular thymic carcinomas with lymphoid hyperplasia, with a mean of 47 (0.2-180) months and 23 (3-39) months, respectively. Patients were alive without disease, except for five micronodular thymoma with lymphoid B-cell hyperplasia patients (dead from unrelated causes), and one micronodular thymic carcinoma with lymphoid hyperplasia patient (dead of disease).

The prognostic value of architectural patterns in a study of 37 type AB thymomas.

Spindle cell thymomas with prominent amount of lymphocytes are classified as WHO type AB tumors. However, there are architectural pattern differences in these tumors. We investigated the importance of architectural pattern in type AB thymomas in relation to prognostic value. Archival hematoxylin-eosin stained slides of 37 AB type thymomas were reviewed for the presence (type 1) or absence (type 2) of reticular growth pattern. Reticular growth pattern is defined as the presence of a network of elongated bland spindle cells separating nests of tumor cells admixed with lymphoid cells. The architectural patterns were correlated with tumor stage at diagnosis and presence or absence of recurrent disease. The analysis identified 18 cases of type 1 AB thymoma and 19 cases of type 2. Type 2 cases also had greater cytologic atypia within the spindle cells. Patients with type 1 tumors were more likely to have early stage disease. In contrast, type 2 pattern was associated with higher stage at diagnosis (P<0.001) and greater likelihood for recurrence (P<0.05) and metastases. Architectural features are prognostically relevant in classification of WHO AB type thymomas and may constitute a form of personalized medicine. Independent confirmation of the findings is necessary to confirm the association of architectural pattern with outcomes.

NUT midline carcinomas in the thymic region.

NUT midline carcinomas (NMCs) are rare tumors described predominantly in the pediatric age group. We recently reported two cases of these tumors occurring in the thymic region. In order to establish the true incidence of these tumors, we examined a large series of thymic carcinomas for morphological features of NUT tumor and further assessed the expression of NUTM1 (also known as NUT) protein by immunohistochemistry. The histological review of slides from 110 cases of thymic carcinoma was undertaken to identify carcinomas with mixed undifferentiated and squamous features that are typically associated with NUT carcinomas. The presenting symptoms, morphological spectrum of tumors and outcome data of patients with these histologies are presented. Immunohistochemistry for NUTM1 was performed on 35 cases of thymic carcinoma with available blocks (3 with these histological features and 32 without these features) to exclude the possibility of midline carcinoma. Tumors from 10 patients had features of mixed small cell undifferentiated squamous cell carcinoma (M:F, 1.5:1; age range, 22-79). These patients predominantly presented with advanced disease and had respiratory-related symptoms or chest pain; four had paraneoplastic syndromes. The squamous component in all cases was well differentiated with little or no atypia. The undifferentiated component varied in cell size and lacked characteristic features of small cell carcinoma. All but one patients developed metastases or died within 3 years of diagnosis. NUTM1 expression was seen in two of three tumors with these histological features and in none of the 32 cases without. Mixed small cell undifferentiated carcinomas share histological and immunohistochemical similarity with NMCs and have aggressive clinical course. These tumors are not uncommon and should be considered in the differential diagnosis of carcinomas in the thymic region as novel therapies might be available.

What Have We Learned from Molecularly Informed Clinical Trials on Thymomas and Thymic Carcinomas-Current Status and Future Directions?

Thymic epithelial tumors (TETs), which include thymomas and thymic carcinomas, are a rare, heterogeneous group of malignancies that originate from the thymus gland. As an important organ of immune cell development, thymic tumors, particularly thymomas, are often associated with paraneoplastic autoimmune disorders. The advances in targeted therapies for both solid and hematologic malignancies have resulted in improved patient outcomes, including better and more durable efficacy and improved toxicity. Targeted therapies have also been investigated in the treatment of TETs, though the results have largely been modest. These have included somatostatin-receptor-targeting therapies, KIT- and EGFR-directed tyrosine kinase inhibitors, epigenetic modulators, anti-angiogenesis agents, and agents targeting the cell proliferation and survival pathways and cell cycle regulators. Numerous investigated treatments have failed or underperformed due to a lack of a strong biomarker of efficacy. Ongoing trials are attempting to expand on previous experiences, including the exploration of effective drugs in early-stage disease. Novel combination therapy strategies are also undergoing evaluation, with the goal of augmenting efficacy and understanding the toxicity while expanding the biomarkers of efficacy and safety. With advances in technology to improve target identification and drug delivery, old targets may become new opportunities, and the subsequently developed drugs may find their place in the treatment of thymic tumors.

Expanding Myeloma Training and Care in Western Kenya Through the ECHO Model: The Pilot Phase.

PURPOSE: Multiple myeloma (MM) in rural western Kenya is characterized by under and late diagnosis with poor long-term outcomes. Inadequate skilled rural health care teams are partly to blame. The Extension for Community Healthcare Outcomes (ECHO) model attempts to bridge this skills gap by linking rural primary/secondary health care teams (spokes) to myeloma experts in a tertiary care center (hub) in a longitudinal training program. METHODS: A hub team comprising myeloma experts and administrators from Moi Teaching and Referral Hospital/Academic Model Providing Access to Healthcare was assembled and spoke sites were recruited from rural health care facilities across western Kenya. A curriculum was developed by incorporating input from spokes on their perceived skills gaps in myeloma. Participants joined sessions remotely through virtual meeting technology. ECHO sessions consisted of a spoke-led case presentation with guided discussion followed by an expert-led lecture. An end-of-program survey was used to evaluate participant satisfaction, knowledge, and practice patterns. RESULTS: A total of eight sessions were conducted between April and November 2021 with a median of 40 attendees per session drawn from diverse health care disciplines. Twenty-four spoke sites were identified from 15 counties across western Kenya. The majority of attendees reported satisfaction with the ECHO program (25 of 29) and improvement in their myeloma knowledge (24 of 29). There were 74 new myeloma diagnoses made at the hub site in 2021, representing a 35% increase from the previous 3-year average despite the COVID-19 pandemic that suppressed health care access globally. RECOMMENDATIONS: The pilot ECHO model was successfully implemented in myeloma training for rural-based health care teams. Key attributes included collaborative curriculum development, interactive case-based bidirectional learning, and multidisciplinary engagement.

Envisioning Academic Global Oncologists: Proposed Competencies for Global Oncology Training From ASCO.

Recognizing the rising incidence, prevalence, and mortality of cancer in low- and middle-resource settings, as well as the increasingly international profile of its membership, ASCO has committed to expanding its engagement at a global level. In 2017, the ASCO Academic Global Oncology Task Force sought to define the potential role for ASCO in supporting global oncology as an academic field. A set of recommendations to advance the status of global oncology as an academic discipline were created through a consensus-based process involving participation by a diverse group of global oncology and global health practitioners; these recommendations were then published. The recommendations included developing a set of global oncology competencies for trainees and faculty interested in a career in academic global oncology. Here, we describe the global oncology competencies developed by this task force. These competencies consist of knowledge and skills needed in general global health as well as cancer-specific care and research, including understanding global cancer health disparities, defining unique resources and needs in low- and middle-resource settings, and promoting international collaboration. Although the competencies were originally developed for US training programs, they are intended to be widely applicable globally. By formalizing the training of oncologists and supporting career pathways in the field of global oncology, we can make progress in achieving global equity in cancer care and control.
