The benefit for radiotherapy at specialised sarcoma centres: A systematic review and clinical practice guidelines from the Australia and New Zealand Sarcoma Association

Patients with sarcoma are best managed at specialised sarcoma centres as supported by published literature. Optimal management requires multidisciplinary team input to formulate the diagnosis and treatment sequencing taking into consideration multiple clinical and pathologic factors. This systematic review aimed to evaluate the impact on outcomes of radiotherapy at specialised sarcoma centres. A systematic review was conducted using the population, intervention, comparison and outcome model. A literature search was performed using Medline, Embase, Cochrane Central databases for publications from 1990 to February 2022 that evaluated the local control, survival and toxicity of radiotherapy at specialised sarcoma centres. A total of 21 studies were included (17 cancer registry studies, four retrospective comparative studies). Four studies reported the local recurrence endpoint when radiotherapy was part of limb conservation treatment and showed better conformity to clinical practice guidelines and an improved local recurrence free rate when radiotherapy treatment is supported through, but may not be necessarily delivered at a specialised sarcoma centres. Only one retrospective study analysed toxicity specifically and demonstrated that patients who received preoperative radiotherapy at community centres compared to radiotherapy at a specialised sarcoma centre were more likely to develop a major wound complication. Fourteen studies reported overall survival, and 12 of these showed significantly better 5-year overall survival for patients managed at specialised sarcoma centres, however the specific impact of radiotherapy delivered at sarcoma centres could not be determined. In conclusion, patients with sarcoma should be managed through specialised sarcoma centres for better oncological outcomes. Radiotherapy in specialised sarcoma centre is associated with a lower rate of wound complications and may contribute to improved oncological outcomes as part of the limb conservation treatment at a specialised sarcoma centre.

Advances in training of the specialized human resources for health in Tanzania: the case of Muhimbili University of Health and Allied Sciences

BACKGROUND

Increasing the number of specialized human resources for health is paramount to attainment of the United Nations sustainable development goals. Higher learning institutions in low-and middle-income countries must address this necessity. Here, we describe the 5-years trends in accreditation of the clinical and non-clinical postgraduate (PG) programmes, student admission and graduation at the Muhimbili University of Health and Allied Sciences (MUHAS) in Tanzania, highlighting successes, challenges and opportunities for improvement.

METHODS

This was a retrospective longitudinal study describing trends in PG training at MUHAS between 2015 and 2016 and 2019-2020. Major interventions in the reporting period included university-wide short course training programme to faculty on curricula development and initiation of online application system. Data were collected through a review of secondary data from various university records and was analyzed descriptively. Primary outcomes were the number of accredited PG programmes, number of PG applicants as well as proportions of applicants selected, applicants registered (enrolled) and students graduated, with a focus on gender and internationalization (students who are not from Tanzania).

RESULTS

The number of PG programmes increased from 60 in 2015-2016 to 77 in 2019-2020, including programmes in rare fields such as cardiothoracic surgery, cardiothoracic anesthesia and critical care. The number of PG applications, selected applicants, registered applicants and PG students graduating at the university over the past five academic years had steadily increased by 79, 81, 50 and 79%, respectively. The average proportions of PG students who applied, were selected and registered as well as graduated at the university over the past five years by gender and internationalization has remained stably at 60% vs. 40% (male vs. female) and 90% vs. 10% (Tanzanian vs. international), respectively. In total, the university graduated 1348 specialized healthcare workers in the five years period, including 45 super-specialists in critical fields, through a steady increase from 200 graduates in 2015-2016 to 357 graduates in 2019-2020. Major challenges encountered include inadequate sponsorship, limited number of academic staff and limited physical infrastructure for teaching.

CONCLUSION

Despite challenges encountered, MUHAS has made significant advances over the past five years in training of specialized and super-specialized healthcare workforce by increasing the number of programmes, enrollment and graduates whilst maintaining a narrow gender gap and international relevance. MUHAS will continue to be the pillar in training of the specialized human resources for health and is thus poised to contribute to timely attainment of the health-related United Nations sustainable development goals in Tanzania and beyond, particularly within the Sub-Saharan Africa region.
