Challenges and Opportunities in Breast Cancer Care in Low-Resourced Countries, Jordan as An Example.

Jordan is a relatively small country with a rapidly growing population and a challenged economy. Breast cancer is the most diagnosed cancer among women worldwide and also in Jordan. Though the age-standardized rate (ASR) of breast cancer incidence is still lower than that in Western societies, the number of newly diagnosed cases continues to increase, involving younger women, and new cases are usually detected at more advanced stages. Improvements in breast cancer care across the health care continuum, including early detection, prevention, treatment, and survivorship and palliative care, have become very visible, but may not match the magnitude of the problem. More organized, goal-oriented work is urgently needed to downstage the disease and improve awareness of, access to, and participation in early detection programs. The cost of recently introduced anti-cancer therapies poses a great challenge, but the impact of these therapies on treatment outcomes, including overall survival, is becoming very noticeable. Though the concept of a multidisciplinary approach to breast cancer treatment is often used at most health care facilities, its implementation in real practice varies significantly. The availability of breast reconstruction procedures, survivorship programs, germline genetic testing, counselling, and palliative care is improving, but these are not widely practiced. In this manuscript, we review the status of breast cancer in Jordan and highlight some of the existing challenges and opportunities.

The Application of Existing Risk Assessment Models (RAMS) to Predict the Occurrence of Venous Thromboembolic Events among Patients with Classic Hodgkin Lymphoma.

Background: A majority of patients included in risk assessment models (RAMs) developed to predict venous thromboembolic events (VTE) in lymphoma were non-Hodgkin lymphoma. Our study aims to evaluate the incidence and predictors of VTE, utilizing different RAMs, in patients with classic Hodgkin lymphoma (cHL) treated with adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD). Methods: Adult patients with cHL, treated and followed at our center, were included. Correlations between different variables, Khorana score, and thrombosis in lymphoma (ThroLy) RAMs with VTE were examined using Fisher's exact test and logistic regression analysis. Results: A total of 321 patients were included, with a median age of 29 (range: 18-83) years. Of them, 169 (52.6%) had advanced-stage disease. Combined modality treatment was given to 169 (52.6%) patients. A total of 52 (16.2%) patients had relapsed or refractory disease. VTE were reported in 15 (4.7%) patients and were mostly during the administration of first-line (n = 8, 53.3%), or salvage chemotherapy (n = 6, 40.0%). There was no correlation between a Khorana score > 2 (p = 0.689) or ThroLy score > 3 (p = 0.335) and VTE. Older age (p = 0.014) and relapsed or refractory disease (p = 0.003) significantly correlated with VTE. Conclusions: VTE are uncommon in cHL. The commonly used RAMs failed to predict VTE. However, older age and relapsed or refractory disease significantly increased this risk.

COMPASS-CAT versus Khorana risk assessment model for predicting venous thromboembolic events in patients with non-small cell lung cancer on active treatment with chemotherapy and/or immunotherapy, the CK-RAM study.

Cancer patients are at higher risk for venous thromboembolism (VTE). Several risk assessment models (RAM), including the Khorana and COMPASS-CAT, were developed to help predict the occurrence of VTE in cancer patients on active anti-cancer therapy. We aim to study the prevalence and predictors of VTE among patients with non-small cell lung cancer (NSCLC) and compare both RAMs in predicting VTE in patients with NSCLC were retrospectively reviewed. Variables known to increase the risk of VTE were collected and risk of VTE was assessed using both Khorana and COMPASS-CAT RAM. A total of 508 patients (mean age ± SD, 58.4 ± 12.2 years) were enrolled. Most (n = 357, 70.3%) patients had adenocarcinoma, and 333 (65.6%) patients had metastatic disease. VTE were confirmed in 76 (15.0%) patients. Rates were higher among patients with metastatic disease (19.8%, p < 0.001), adenocarcinoma (17.4%, p = 0.01) and those treated with immunotherapy (23.5%, p = 0.014). VTE rates were 21.2%, 14.1% and 13.9% among those with high (n = 66), intermediate (n = 341) and low (n = 101) Khorana risk scores, respectively (p = 0.126). On the other hand, 190 (37.4%) were classified as high risk by the COMPASS-CAT RAM; 52 (27.4%) of them had VTE compared to 24 (7.5%) of the remaining 318 (62.6%) classified as Low/Intermediate risk level, p < 0.001. In conclusion, patients with NSCLC are at high risk for VTE, especially those with adenocarcinoma, metastatic disease and when treated with immunotherapy. Compared to Khorana RAM, COMPASS-CAT RAM was better in identifying more patients in high-risk group, with higher VTE rate.

Comparative Assessment of the Kinetics of Cellular and Humoral Immune Responses to COVID-19 Vaccination in Cancer Patients.

OBJECTIVE: The kinetics of immune responses to various SARS-CoV-2 vaccines in cancer patients were investigated. METHODS: In total, 57 cancer patients who received BNT162b2-RNA or BBIBP-CorV vaccines were enrolled. Cellular and humoral immunity were assessed at three-time points, before the first vaccine dose and 14-21 days after the first and second doses. Chemiluminescent microparticle immunoassay was used to evaluate SARS-CoV-2 anti-spike IgG response, and QuantiFERON® SARS-CoV-2 kit assessed T-cell response. RESULTS: Data showed that cancer patients' CD4+ and CD8+ T cell-median IFN-γ secretion of SARS-CoV-2 antigens increased after the first and second vaccine doses (p = 0.027 and p = 0.042). BNT162b2 vaccinees had significantly higher IFN-γ levels to CD4+ and CD8+ T cell epitopes than BBIBP-CorV vaccinees (p = 0.028). There was a positive correlation between IgG antibody titer and T cell response regardless of vaccine type (p < 0.05). CONCLUSIONS: This study is one of the first to investigate cellular and humoral immune responses to SARS-CoV-2 immunization in cancer patients on active therapy after each vaccine dose. COVID-19 immunizations helped cancer patients develop an effective immune response. Understanding the cellular and humoral immune response to COVID-19 in cancer patients undergoing active treatment is necessary to improve vaccines and avoid future SARS pandemics.

Supportive Care Needs Assessment for Cancer Survivors at a Comprehensive Cancer Center in the Middle East: Mending the Gap.

BACKGROUND: Cancer survivors are often underprepared for what to expect post-treatment, and there are knowledge gaps regarding cancer survivors' supportive care needs in Jordan and neighboring Arab countries. This study aimed to identify gaps in supportive care needs among adult cancer survivors seen at King Hussein Cancer Center in Amman, Jordan, and explore predictors of unmet needs. METHODS: This was an observational cross-sectional study using a modified version of the Supportive Care Needs Survey 34 item short form (SCNS-SF34). RESULTS: Two hundred and forty adult cancer survivors completed the study questionnaire. The assessed needs were highest in the financial domain, including covering living expenses, managing cancer treatment adverse effects and co-morbidities. The least prevalent reported needs were in sexuality and reproductive consultations. Late-stage diagnosis was independently associated with higher physical, psychological, health system/information, financial and overall need scores, with p-values of 0.032, 0.027, 0.052, 0.002 and 0.024, respectively. The overall quality of life score was independently and inversely associated with physical, psychological, health system/information, financial and overall need domains, with p-values of 0.015, <0.0001, 0.015, 0.004 and 0.0003, respectively. CONCLUSIONS: This needs assessment identified problem areas for targeting interventions across the Jordanian cancer survivor population, and understanding these findings highlights opportunities for intervention to address gaps in care.

The Application of the ThroLy Risk Assessment Model to Predict Venous Thromboembolism in Patients with Diffuse Large B-Cell Lymphoma.

BACKGROUND: Patients with aggressive lymphomas are at higher risk for venous thromboembolism (VTE). ThroLy is a risk assessment model (RAM) derived to predict the occurrence of VTE in various types of lymphomas. In this study, we assess the clinical application of ThroLy RAM in a unified group of patients with diffuse large B-cell lymphoma (DLBCL). METHODS: Hospital databases were searched for patients with DLBCL and radiologically-confirmed VTE. Items in the ThroLy RAM, including prior VTE, reduced mobility, obesity, extranodal disease, mediastinal involvement, neutropenia and hemoglobin < 10.0 g/dL, were retrospectively reviewed. RESULTS: A total of 524 patients, median age 49 (range: 18-90) years were included. Patients had high disease burden; 57.3% with stage III/IV and 34.0% with bulky disease. All were treated on unified guidelines; 63 (12.0%) had primary refractory disease. Venous thromboembolic events were reported in 71 (13.5%) patients. Among 121 patients with high (> 3) ThroLy score, 22.3% developed VTE compared to 8.4% and 12.4% in those with low and intermediate risk scores, respectively (P = .014). Simplifying the ThroLy model into two risk groups; high-risk (score ≥ 3) and low risk (score < 3) can still segregate patients; VTE developed in 44 (17.2%) high-risk patients (n = 256) compared to 27 (10.1%) in the low-risk group (n = 268), P = .038. Neutropenia, a component of the ThroLy, was encountered in only 14 (2.7%) patients. CONCLUSIONS: ThroLy RAM can identify patients with DLBCL at high risk for VTE. Model can be modified by dividing patients into two, rather than three risk groups, and further simplified by omitting neutropenia.

Gaining Palliative Medicine Subspecialty Recognition and Fellowship Accreditation in Jordan.

CONTEXT: Palliative medicine (PM) has gained subspecialty recognition in many countries during the past two decades. Jordan is one of the first Arab countries to gain accreditation for the specialty. OBJECTIVES: To outline the process undertaken by leaders in palliative care in Jordan to have PM recognized as a subspecialty and the development of a two-year fellowship training program. To contextualize the Jordanian experience with the experience from other countries and assess the need for PM specialty programs in Jordan. METHODS: A thorough review of all documentations, letters, correspondence, and proposals exchanged between the palliative care department at King Hussein Cancer Center and the Jordanian Medical Council from 2011 to 2017. An assessment of the number of certified physicians and fellowship posts required to meet the current palliative care needs in Jordan, using population-based need for palliative care. RESULTS: The process of gaining subspecialty status for PM in Jordan was complex, lengthy, and dependent on the collaboration of many officials and health sector organizations working together on a national strategy to achieve it. Ultimately, PM was recognized as a subspecialty in 2017, a two-year fellowship program was accredited by the Jordanian Medical Council in 2018, with a recognized subspecialty board examination, which can be accessed by many medical and surgical specialties. It is estimated that 185-235 full-time equivalent palliative care specialist physicians are needed to meet the demand of patients in Jordan. CONCLUSION: Key factors enabling accreditation to happen in Jordan were strong leadership, persistence, collaboration with major stakeholders, and seeking out opportunities to promote the specialty. Our experience and lessons learnt are transferable to other countries and may prove beneficial to others aiming to gain subspecialty recognition for PM.

Cancer care for adolescents and young adults in Jordan.

BACKGROUND: Adolescents and young adults with cancer have special characteristics and needs. AIMS: This study highlighted psychosocial challenges, fertility issues and secondary diseases encountered in adolescents and young adults with cancer. This work is meant to be a platform for future interventions for cancer in this demographic. METHODS: We investigated the latest edition of the Jordan Cancer Registry (JCR) and our more comprehensive institutional database during 2000-2012. Smoking, obesity and fertility preservation were addressed briefly as important issues among AYA patients. RESULTS: Cancer among adolescents and young adults represents 16.3% of all new cancer cases and has increased by 25% over the past 12 years. Women are more likely to be involved (female: male ratio of 1.44: 1) because of thyroid and breast cancers. Five-year survival rate for the AYA group was 72.4%, which was significantly better than for adults aged ≥ 40 years (59.8%) but worse than for paediatric patients aged < 15 years (79.2%) (P < 0.0001). CONCLUSIONS: Cancer in adolescents and young adults represents a substantial and growing proportion of oncological diagnoses. Due to their special needs and treatment complications, a dedicated service is urgently needed.

The Application of Current Proposed Venous Thromboembolism Risk Assessment Model for Ambulatory Patients With Cancer.

Venous thromboembolism (VTE) is a commonly encountered problem in patients with cancer. In recent years, cancer treatment paradigm has shifted with most therapy offered in ambulatory outpatient settings. Excess of half VTEs in patients with cancer occur in outpatient settings without prior hospitalization, where current practice guidelines do not recommend routine prophylaxis. Risk assessment models (RAMs) for VTE in such patients were recently introduced. This study aims to assess the practical application of one of these models in clinical practice. Medical records and hospital electronic database were searched for patients with cancer having VTE. Known risk factors were collected, and risk assessment was done using the Khorana RAM. Over a 10-year period, 346 patients developed VTE in ambulatory settings. Median age was 57 and 59.0% were females. Lower extremities were involved in 196 (56.6%), while 96 (27.7%) had pulmonary embolism. Most (76.6%) patients had stage IV disease, only 9.0% had stage I or II disease. Only 156 (45.1%) patients were on active chemotherapy, for whom Khorana risk assessment score was calculated. In these patients, high risk was identified in 31 (19.9%) patients, while 81 (51.9%) had intermediate risk and 44 (28.2%) had low risk. No patients were on prophylaxis prior to VTE. Most ambulatory patients with cancer who developed VTE were not on chemotherapy, and many of those who were on active treatment had low Khorana risk scores. This illustrates the need to modify the model or develop a new one that takes into consideration this group of patients.
