A 78-year old man underwent low anterior resection for Stage IIIb rectal cancer(Ra). After surgery, he underwent the Roswell Park Memorial Institute(RPMI)regimen for 6 months followed by oral UFT for 8 months. Since liver metastasis(S6)recurred 2 years and 2 months after surgery, he underwent S6 subsegmentectomy. Four years and 4 months later, he developed multiple lymph node metastases(the Virchow, paraaortic, and intrapelvic lymph nodes), for which FOLFIRI therapy was started, but converted to the RPMI regimen because of strong gastrointestinal side effects. After 3 courses of this regimen, tumor markers returned to normal, and imaging studies showed that the metastases had disappeared. This was interpreted as a complete response(CR). The patient has maintained the complete response for 1 year and 4 months since the start of the RPMI regimen.

Central nervous system tuberculosis (CNS-TB) is a severe form of extra-pulmonary tuberculosis with high mortality and morbidity rates. The standard treatment regimen for CNS-TB parallels that of pulmonary TB, despite the challenge posed by the blood-brain barrier (BBB), which limits the efficacy of first-line anti-TB drugs (ATDs). Nose-to-brain (N2B) drug delivery offers a promising solution for achieving high ATD concentrations directly at infection sites in the brain while bypassing the BBB.

Correlative studies of clinical studies for hematological malignancies have implicated that less differentiated, CD8+-dominant CAR T cell products have greater antitumor activity. Here, we have investigated whether the differentiation status of CAR T cell products affects their antitumor activity in preclinical models of solid tumors. We explored if different activation/expansion protocols, as well as different co-stimulatory domains in the CAR construct, influence the short- and long-term efficacy of CAR T cells against HER2-positive tumors.

HDAC inhibitors (HDACis) have been intensively studied for their roles and potential as drug targets in T-cell lymphomas and other hematologic malignancies. Bisthianostat is a novel bisthiazole-based pan-HDACi evolved from natural HDACi largazole. Here, we report the preclinical study of bisthianostat alone and in combination with bortezomib in the treatment of multiple myeloma (MM), as well as preliminary first-in-human findings from an ongoing phase 1a study.

The monocyte-derived dendritic cells (moDCs) are a subset of dendritic cells widely used in immunological studies as a convenient and easy approach after isolation of mononuclear cells directly from peripheral blood mononuclear cells (PBMC). Both the purification and cell culture of monocytes impact on the differentiation of monocytes into moDCs. The methodology to isolate and differentiate monocytes into moDCs is still controversial.
