BACKGROUND: Peripheral T-cell lymphoma (PTCL) is a rare form of non-Hodgkin's lymphoma (NHL), and it is usually associated with poor outcome. Here, we report our experience in treating this disease over 19 years, with the aim of helping to establish better treatment methods.METHODS: We retrospectively investigated 18 non-anaplastic PTCL cases that were diagnosed at a medical center in Seoul between October 1995 and October 2014. The clinical characteristics, treatments, and outcomes were reviewed.RESULTS: According to the World Health Organization (WHO) classifications for PTCL, 11 patients had PTCL, not otherwise specified (PTCL-NOS), 6 patients had extranodal natural killer/T-cell lymphoma, nasal type (ENKL), and 1 patient had subcutaneous panniculitis-like T-cell lymphoma. Patients were treated with various chemotherapeutic regimens. Of these 18 patients, 5 (27.7%) relapsed and 7 (38.9%) died from disease progression. Two relapsed patients received high-dose chemotherapy with autologous hematopoietic stem cell transplantation (HDCT-ASCT). The 5-year event-free and overall survival rates were 43.2% and 66.7% in all cases, 45.5% and 54.5% in PTCL-NOS, and, 25.0% and 83.3% in ENKL, respectively.CONCLUSION: PTCL-NOS showed a suboptimal outcome. Among 6 ENKL patients, 3 relapsed, but 2 of 3 relapsed patients were salvaged. For better prognosis, HDCT-ASCT in relapsing and refractory PTCL and chemo-radiotherapy in ENKL could be considered as a salvage treatment. Larger studies are needed to confirm the outcome. Furthermore, an effort should be made to develop more efficient initial therapies through collaborative research.

Purpose: This study aimed to evaluate the use of active surgical co-management (SCM) by medical hospitalists for urology inpatient care. Materials and Methods: Since March 2019, a hospitalist-SCM program was implemented at a tertiary-care medical center, and a retrospective cohort study was conducted among co-managed urology inpatients. We assessed the clinical outcomes of urology inpatients who received SCM and compared passive SCM (co-management of patients by hospitalists only on request; March 2019 to June 2020) with active SCM (co-management of patients based on active screening by hospitalists; July 2020 to October 2021). We also evaluated the perceptions of patients who received SCM toward inpatient care quality, safety, and subjective satisfaction with inpatient care at discharge or when transferred to other wards. Results: We assessed 525 patients. Compared with the passive SCM group (n=205), patients in the active SCM group (n=320) required co-management for a significantly shorter duration (p=0.012) and tended to have a shorter length of stay at the urology ward (p=0.062) and less frequent unplanned readmissions within 30 days of discharge (p=0.095) while triggering significantly fewer events of rapid response team activation (p=0.002). No differences were found in the proportion of patients transferred to the intensive care unit, in-hospital mortality rates, or inpatient care questionnaire scores. Conclusion Active surveillance and co-management of urology inpatients by medical hospitalists can improve the quality and efficacy of inpatient care without compromising subjective inpatient satisfaction.
