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.

Long-term efficacy and safety of CT-P6 versus trastuzumab in patients with HER2-positive early breast cancer: final results from a randomized phase III trial.

PURPOSE: Equivalent efficacy was demonstrated for the biosimilar CT-P6 and trastuzumab following neoadjuvant therapy for patients with human epidermal growth factor receptor-2 (HER2)-positive early breast cancer. Following adjuvant treatment, efficacy and safety were comparable between treatments. We report updated safety and efficacy data after up to 3 years' follow-up. METHODS: Following neoadjuvant chemotherapy with CT-P6/trastuzumab, patients underwent surgery and continued receiving adjuvant CT-P6/trastuzumab. The primary endpoint (previously reported) was pathological complete response. Time-to-event analyses (disease-free survival [DFS], progression-free survival [PFS], and overall survival [OS]), study drug-related and cardiac adverse events, and immunogenicity were assessed during post-treatment follow-up. RESULTS: Most patients entered the follow-up period (CT-P6: 259 [95.6%]; trastuzumab: 269 [96.8%]). After a median follow-up of 38.7 (CT-P6) and 39.6 (trastuzumab) months, medians were not reached for time-to-event parameters; estimated hazard ratios (HRs) and 3-year survival rates were similar between groups. Estimated HRs (95% confidence intervals) for CT-P6 versus trastuzumab were 1.23 (0.78-1.93) for DFS, 1.31 (0.86-2.01) for PFS, and 1.10 (0.57-2.13) for OS (intention-to-treat population). Safety findings were comparable between groups for the overall study and follow-up period, including study drug-related cardiac disorders (CT-P6: 22 [8.1%] patients; trastuzumab: 24 [8.6%] patients [overall]) and decreases in left ventricular ejection fraction. Immunogenicity was similar between groups. CONCLUSION: The similarity of the time-to-event analyses between CT-P6 and trastuzumab supports the equivalence in terms of efficacy established for the primary endpoint. CT-P6 was well tolerated, with comparable safety and immunogenicity to trastuzumab. ClinicalTrials.gov: NCT02162667 (registered June 13, 2014).

Recommendations from the ASCO Academic Global Oncology Task Force.

In recognition of the rising incidence and mortality of cancer in low- and middle-resource settings, as well as the increasingly international profile of its membership, ASCO has prioritized efforts to enhance its engagement at a global level. Among the recommendations included in the 2016 Global Oncology Leadership Task Force report to the ASCO Board of Directors was that ASCO should promote the recognition of global oncology as an academic field. The report suggested that ASCO could serve a role in transitioning global oncology from an informal field of largely voluntary activities to a more formal discipline with strong research and well-defined training components. As a result of this recommendation, in 2017, ASCO formed the Academic Global Oncology Task Force (AGOTF) to guide ASCO's contributions toward formalizing the field of global oncology. The AGOTF was asked to collect and analyze key issues and barriers toward the recognition of global oncology as an academic discipline, with an emphasis on training, research, and career pathways, and produce a set of recommendations for ASCO action. The outcome of the AGOTF was the development of recommendations designed to advance the status of global oncology as an academic discipline.

Cancer Care and Control as a Human Right: Recognizing Global Oncology as an Academic Field.

The global burden of cancer incidence and mortality is on the rise. There are major differences in cancer fatality rates due to profound disparities in the burden and resource allocation for cancer care and control in developed compared with developing countries. The right to cancer care and control should be a human right accessible to all patients with cancer, regardless of geographic or economic region, to avoid unnecessary deaths and suffering from cancer. National cancer planning should include an integrated approach that incorporates a continuum of education, prevention, cancer diagnostics, treatment, survivorship, and palliative care. Global oncology as an academic field should offer the knowledge and skills needed to efficiently assess situations and work on solutions, in close partnership. We need medical oncologists, surgical oncologists, pediatric oncologists, gynecologic oncologists, radiologists, and pathologists trained to think about well-tailored resource-stratified solutions to cancer care in the developing world. Moreover, the multidisciplinary fundamental team approach needed to treat most neoplastic diseases requires coordinated investment in several areas. Current innovative approaches have relied on partnerships between academic institutions in developed countries and local governments and ministries of health in developing countries to provide the expertise needed to implement effective cancer control programs. Global oncology is a viable and necessary field that needs to be emphasized because of its critical role in proposing not only solutions in developing countries, but also solutions that can be applied to similar challenges of access to cancer care and control faced by underserved populations in developed countries.

Treatment of breast cancer in countries with limited resources.

Early and accurate diagnosis of breast cancer is important for optimizing treatment. Local treatment of early stage breast cancer involves either mastectomy or breast-conserving surgery followed by whole-breast irradiation. The pathologic and biologic properties of a woman's breast cancer may be used to estimate her probability for recurrence of and death from breast cancer, as well as the magnitude of benefit she is likely to receive from adjuvant endocrine therapy or cytotoxic chemotherapy. Ovarian ablation or suppression with or without tamoxifen is an effective endocrine therapy in the adjuvant treatment of breast cancer in premenopausal women with estrogen receptor (ER)-positive or ER-unknown breast cancer. In postmenopausal women with ER- and/or progesterone receptor (PR)-positive or PR-unknown breast cancer, the use of tamoxifen or anastrozole is effective adjuvant endocrine therapy. The benefit of tamoxifen is additive to that of chemotherapy. Cytotoxic chemotherapy also improves recurrence rates and survival, with the magnitude of benefit decreasing with increasing age. Substantial support systems are required to optimally and safely use breast-conserving approaches to local therapy or cytotoxic chemotherapy as systemic therapy. Locally advanced breast cancer (LABC) accounts for at least half of all breast cancers in countries with limited resources and has a poor prognosis. Initial treatment of LABC with anthracycline-based chemotherapy is standard and effective. Addition of a sequential, neoadjuvant taxane thereafter increases the rate of pathologic complete responses. Neoadjuvant endocrine therapy may benefit postmenopausal women with hormone receptor-positive LABC. After an initial response to neoadjuvant chemotherapy, the use of local-regional surgery is appropriate. Most women will require a radical or modified radical mastectomy. In those women in whom mastectomy is not possible after neoadjuvant chemotherapy, the use of whole-breast and regional lymph node irradiation alone is appropriate. In those women who cannot receive neoadjuvant chemotherapy because of resource constraints, mastectomy with node dissection, when feasible, may still be considered in an attempt to achieve local-regional control. After local-regional therapy, most women should receive additional systemic chemotherapy. Women with LABC that has a positive or unknown hormone receptor status benefit from endocrine therapy with tamoxifen. The treatment of LABC requires multiple disciplines and is resource intensive. Efforts to reduce the number of breast cancers diagnosed at an advanced stage thus have the potential to improve rates of survival while decreasing the use of limited resources.
