Regorafenib in previously treated advanced hepatocellular carcinoma: Impact of prior immunotherapy and adverse events.

BACKGROUND & AIMS: Regorafenib demonstrated a clinical benefit for patients with unresectable hepatocellular carcinoma (uHCC) in the phase III RESORCE trial. Considering the heterogeneity of uHCC and discrepancies in its characteristics between prospective trials and daily practice, real-life evidence is necessary. METHODS: This multicentre, retrospective analysis was performed by the Korean Cancer Study Group. In total, 440 patients who received regorafenib between January 2017 and November 2019 were identified in nine tertiary referral hospitals in Korea. RESULTS: All patients received prior sorafenib, and the median time-to-progression (TTP) on sorafenib was 3.9 months (range, 0.2-71.6). Regorafenib was used as the second, third and fourth to seventh lines of therapy in 305 (69.3%), 115 (26.1%) and 20 (4.5%) patients respectively. According to the RECIST v1.1, the overall response rate was 7.7% (n = 34), and the median progression-free survival (PFS) and overall survival (OS) were 3.2 (95% CI, 2.8-3.5) and 12.1 (95% CI, 9.7-14.5) months respectively. Immune checkpoint inhibitors (ICIs) were given in 115 patients (26.1%) prior to regorafenib. There were no differences in PFS and OS with regorafenib according to the prior use of ICIs (PFS, P = .61; OS, P = .63). The occurrence of hand-foot skin reaction (HFSR) was associated with a better OS (P < .001). CONCLUSIONS: The real-life clinical outcomes of regorafenib for patients who progressed on prior systemic therapy including ICIs were consistent with the phase III trial results. HFSR was significantly associated with better OS with regorafenib.

Posttraumatic hemidystonia treated with unilateral globus pallidus interna stimulation: Long-term follow-up and radiologic features.

OBJECTIVE: Hemidystonia is a unilateral clinical presentation of dystonia, and it is usually refractory to current methods of medical treatment. Recently, deep brain stimulation has given some hope of recovery to dystonic patients. MATERIALS AND METHODS: A 30-year-old right-handed man with no abnormal perinatal history or family history of movement disorders was admitted to our institution. The patient had suffered right-sided dystonia for more than three years after severe head trauma sustained four years prior. RESULTS: We performed a stereotactic implantation of an electrode into the left globus pallidus internus (GPi) and he showed excellent response to pallidal stimulation during long-term follow-up. CONCLUSIONS: We present a unique case of secondary posttraumatic hemidystonia treated with contralateral GPi stimulation with an excellent outcome. Pallidal stimulation can be a good treatment option for posttraumatic hemidystonia in selected cases.

Clinical features and treatment outcomes of angioimmunoblastic T-cell lymphoma.

The objective of this retrospective study was to investigate clinical features and treatment outcomes in patients with angioimmunoblastic T-cell lymphoma (AITL), data of which were collected over a 15-year period. Sixty-five patients diagnosed with AITL were included in the study. About half of the patients (46.2%) presented with poor performance status (ECOG > or = 2); 72.3% of patients belonged to high intermediate or high-risk of IPI and same proportion belonged to Class 2 of PIT (Prognostic index for PTCL-U), and most patients (95.4%) were diagnosed at an advanced stage. At diagnosis, 27 patients (41.5%) presented with malignant pleural effusion, and 22 patients (33.8%) had skin involvement. Most of the initial chemotherapy regimens were anthracycline-based (88.2%). Overall response rate to initial chemotherapy was 86.2% (64.7% of complete response, 21.5% of partial response). The median progression-free survival and overall survival of all patients was 7.1 months (95% CI, 2.8 - 11.4) and 15.1 months (95% CI, 6.7 - 23.5), respectively. Age, performance status, and PIT scores were predictive prognostic factors for survival. In conclusion, although AITLs showed a good response to the initial chemotherapy, their response durations were short; therefore, chemotherapy for AITL should be modified or intensified as in high-dose chemotherapy.
