A recent study reports a mean growth rate of proximal aorta of about 0.1 mm/year in hypertensive patients with known aortic dilatation. In addition, those with increased rather than normal aortic z score have slower dilatation over time.

Knee osteoarthritis (OA), whether symptomatic or radiographic, contributes to an increased risk of all-cause mortality, with the risk increase from symptomatic knee OA partially attributed to its effect on disability and quality of life (QoL).

PTCL, NKTCL prognosis bad in seniors

21 Jan 2020

Peripheral T cell (PTCL) and natural killer/T cell (NKTCL) non-Hodgkin lymphoma have poor prognoses in elderly adults, though intensive chemotherapy may yield benefit for some, a recent study has found.

Accessing Taiwan’s nationwide, multicentre registry, researchers identified 127 patients (median age, 69 years) with either PTCL and NKTCL. Outcomes included progression-free survival (PFS), overall survival (OS) and the cumulative incidence of relapse.

Ninety-seven (76 percent) patients received systemic chemotherapy, among which doxorubicin-containing multiagent regimens were the most popular (75.5 percent; n=74). Chemotherapy was delivered after a median of 20 days after diagnosis and ran for a median of 5 cycles over 19 weeks. The median follow-up time was 17.3 months.

Eighty-three deaths were reported. The 2-year PFS was 38.1 percent, while the OS estimate over the same time span was 48.5 percent. Both PFS (p=0.015) and OS (p=0.003) were significantly better in patients <75 vs 75 years of age. Survival rates were comparable, however, between PTCL and NKTCL.

Seventy-seven patients who had undergone intensive chemotherapy were available for evaluation. Both 2-year PFS (p=0.05) and OS (p=0.01) were significantly better in these patients than in those who had received less stringent treatments or the best supportive care. The overall response rate was 59.8 percent, with 50.5 percent showing complete remission. Sixty-three patients saw disease relapse or progression.

Multivariable Cox proportional hazards analysis confirmed that undergoing an intensive regiment of multi-agent chemotherapy increases the likelihood of better PFS and OS. Being older and having poor Eastern Cooperative Oncology Group status, on the other hand, were associated with worse prognosis.
