Radiotherapy of brain metastasis from lung cancer in limited resource settings

Radiotherapy is one of the most commonly used treatment modality for brain metastases from lung cancer. Its use has evolved from conventional whole brain radiation therapy (WBRT) to more sophisticated stereotactic radiosurgery (SRS) and hippocampal sparing radiotherapy. Indications of cranial radiotherapy are also evolving with the advent of targeted therapies directed against molecular markers like epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK). Prognostic criteria such as recursive partitioning analyses and graded prognostic score helps in prognostication of brain metastases patients. Majority of the prospective and randomized studies of brain metastases from lung cancer have come from the developed countries with adequate resources. Efforts have been made to replicate or validate the data in developing countries. In this overview, we intend to discuss the role of radiotherapy for brain metastases in limited resource settings of developing countries. The aim should be to generate a good quality data which is applicable for routine clinical practice in a resource friendly manner. SRS is indicated in guidelines for limited brain metastases, however, it requires a more sophisticated treatment delivery and quality assurance machines which are not available at many centres in majority of the developing countries. Similarly, clinical research should be undertaken considering the demographic, clinical and genetic differences among different populations. Currently, tyrosine kinase inhibitors have dramatically changed the outcomes of metastatic non-small cell lung cancer including brain metastases. The role of WBRT is being questioned in driver mutated patients in developed countries. However, the applicability of this approach should be examined in resource constrained settings as availability of these drugs is limited, its higher cost and frequent use of surveillance brain imaging are the practical challenges.

Humanism in global oncology curricula: an emerging priority

Introduction

Training in humanism provides skills important for improving the quality of care received by patients, achieving shared decision-making with patients, and navigating systems-level challenges. However, because of the dominance of the biomedical model, there is potentially a lack of attention to humanistic competencies in global oncology curricula. In the present study, we aimed to explore the incorporation of humanistic competencies into global oncology curricula.

Methods

This analysis considered 17 global oncology curricula. A curricular item was coded as either humanistic (as defined by the iecares framework) or non-humanistic. If identified as humanistic, the item was coded using an aspect of humanism, such as Altruism, from the iecares framework. All items, humanistic and not, were coded under the canmeds framework using 1 of the 7 canmeds competency domains: Medical Expert, Communicator, Collaborator, Leader, Scholar, Professional, or Health Advocate.

Results

Of 7792 identified curricular items in 17 curricula, 780 (10%) aligned with the iecares humanism framework. The proportion of humanistic items in individual curricula ranged from 2% to 26%, and the proportion increased from 3% in the oldest curricula to 11% in the most recent curricula. Of the humanistic items, 35% were coded under Respect, 31% under Compassion, 24% under Empathy, 5% under Integrity, 2% under Excellence, 1% under Altruism, and 1% under Service. Within the canmeds domains, the humanistic items aligned mostly with Professional (35%), Medical Expert (31%), or Communicator (25%).

Conclusions

The proportion of humanistic competencies has been increasing in global oncology curricula over time, but the overall proportion remains low and represents a largely Western perspective on what constitutes humanism in health care. The representation of humanism focuses primarily on the iecares attributes of Respect, Compassion, and Empathy.
