New horizons in managing older cancer survivors: complexities and opportunities.

Older adults represent a growing population amongst cancer survivors who require specific consideration given the complex and largely unknown interactions between cancer-related concerns and age-related conditions. The increasing use of geriatric assessment (GA) has enabled oncologists to appropriately assess older patients' overall health status, personalise anti-cancer treatment and improve survival. However, whilst current research and practice focus on improving the management of older adults with cancer in the acute setting, the progress in the field of survivorship research in geriatric oncology is lagging. As cancer survivorship is a continuum, planning for a healthy survivorship should start at the time of cancer diagnosis. GA can play an important role in identifying potential survivorship issues and optimising delivery of survivorship care. A goal-directed, patient-focused geriatric survivorship care plan that involves a multidisciplinary team provides a framework for a personalised delivery of survivorship care in this patient group and there is a need for tailored interventions that support self-management and care integration. Research on the impact of cancer and its treatment on geriatric-specific outcomes needs to be prioritised through global initiatives to encompass a diverse and heterogenous population of adult cancer survivors.

First-in-Human Study for a Selective Rearranged During Transfection Tyrosine Kinase Inhibitor, GSK3352589, to Investigate the Safety, Tolerability, and Pharmacokinetics in Healthy Volunteers.

Rearranged during transfection (RET), a neuronal growth factor receptor tyrosine kinase, regulates the development of sympathetic, parasympathetic, motor, and sensory neurons in the enteric nervous system. The intended site of action for GSK3352589 is intestinal tissues. GSK3352589 is an RET kinase inhibitor that was administered in double-blind, randomized, placebo-controlled single-dose (SD) and repeat-dose (RD) studies in healthy subjects to investigate its safety/tolerability and pharmacokinetics. In the SD study (n = 28), GSK3352589 was dosed from 2 to 400 mg, including a food effect arm (25 mg). In the RD study (n = 40), GSK3352589 was dosed for 14 days with food twice daily from 5 to 200 mg. With single (fed and fasted) and repeat (fed) doses, bioavailability was low and less than dose-proportional. There was a food effect with 25 mg once daily but may not be clinically relevant. Elimination half-life was ≥17 hours at SD ≥ 15 mg. Accumulation ratios for Cmax , AUCt , AUCtau , and AUC24 after twice-daily dosing to steady state ranged from 1.2 to 1.8 for all doses except the 200-mg dose, which had ratios between 1.9 and 2.7. Administration of GSK3352589 after SD and RD was well tolerated with no safety concerns in healthy subjects.

Comprehensive geriatric assessment predicts azacitidine treatment duration and survival in older patients with myelodysplastic syndromes.

BACKGROUND: Treatment of older patients with myelodysplastic syndrome (MDS) is based on disease biology and performance status. Performance status, however, does not reflect increasing co-morbidities, functional dependence or psychosocial issues in older patients. PATIENTS AND METHODS: This prospective study evaluated the burden of geriatric related health issues, assessed feasibility of "tailored" Comprehensive Geriatric Assessment (CGA), and compared treatment duration and survival in older patients with MDS and oligoblastic acute myeloid leukemia with and without deficits in CGA domains (n = 98). RESULTS: Although only 27 (28%) patients had an Eastern Cooperative Oncology Group score ≥2, 78% (n = 77) patients had deficits in at least one CGA domain. Deficits were spread across all CGA domains, including dependence for instrumental activity of daily living (iADL; n = 33, 34%). Importantly, patients who were dependent for iADL (3.7 ±â€¯2.6 vs 12.1 ±â€¯7.9; p = .009), had cognitive impairment (3.5 ±â€¯2.1 vs. 10.9 ±â€¯7.9; p = .034) or impaired mobility (3.8 ±â€¯2.5 vs. 13.2 ±â€¯7.6; p = .001) completed significantly less azacitidine cycles as compared to those without these deficits. Cox-proportional regression showed that iADL dependency (hazard ratio 3.37; p = .008) and higher comorbidities (hazard ratio 4.7; p < .001) were associated with poor prognosis independent of disease related factors. Poor survival of iADL dependent patients was seen in both azacitidine (6 vs 19 months; p < .001) and supportive care cohorts (26 vs 48 months; p = .01). CONCLUSION: CGA detected geriatric related health issues, predicted poor survival and identified patients less likely to continue and benefit from azacitidine. Hence, CGA should be included in the treatment decision algorithm of older patients with MDS.
