RESUMEN
In cases where carcinomatous meningitis leads to hydrocephalus and increases intracranial pressure, patients present with exacerbated pain and several neurological symptoms. It is reported that multidisciplinary therapy, including radiation therapy, drug therapy, and surgery, is performed for patients with carcinomatous meningitis; however, it is rarely successful. Ventriculoperitoneal shunting(V-P shunt)is a surgical intervention that might relieve the pain temporarily and improve the quality of life. VPS should be taken into consideration in line with patients' and their families' intentions since the overall survival is fairly short.

Nodular lymphocyte-predominant Hodgkin lymphoma(NLPHL)is a subtype of Hodgkin lymphoma. It is uncommon in Japan, and only a few cases of NLPHL originating from the mesentery have been reported. Most patients with NLPHL present in the early stage, but some patients have malignancy at initial presentation. We should perform staging laparotomy for the diagnosis and treatment of cases in which a lymph node biopsy is difficult.

A phase-â ¡trial of TAS-102 plus bevacizumab(Bev)combination therapy showed a progression-free survival(PFS)of 3.7-4.6 months. Here, we report 12 cases of unresectable advanced recurrent colorectal cancer treated with TAS-102 plus Bev therapy at our hospital between June 2017 and February 2020. The median PFS was 6 months(2-12). Adverse events greater than Grade 3 were neutropenia(33.3%), febrile neutropenia(8.3%), thrombocytopenia(8.3%), and vomiting (8.3%). The frequency of non-hematotoxicity was low. In conclusion, the TAS-102 plus Bev therapy may be a useful option for the late-line treatment of unresectable advanced recurrent colorectal cancer.

Robot-assisted laparoscopic surgery(RALS)for rectal cancer has been covered by National Health Insurance in Japan since April 2018. We launched RALS in our hospital in October 2019 and now report the short-term results(up to January 2020). Altogether, 15 consecutive patients(12 men, 3 women: median age 70 years)with rectal cancer underwent RALS during that period. For the first 2 cases, we performed RALS under the instruction of an experienced proctor from another institution. Among the 15 patients, 6 underwent high anterior resection and 9 low anterior resection. Median operating time was 358 min, median intraoperative blood loss was 0 mL, and there were no apparent intraoperative complications. Median postoperative length of hospital stay was 13 days, and only 1 patient developed a high-grade complication(Clavien-Dindo Grade â ¢b)postoperatively. Hence, RALS for rectal cancer was launched successfully in our institution.

Nucleoside diphosphate kinases (NDPK) are ubiquitous enzymes that catalyze the reversible phosphotransfer of γ-phosphates between di- and triphosphonucleosides. NDPK-D (Nm23-H4) is the only member of the NDPK family with a mitochondrial targeting sequence. Despite the high expression of NDPK-D in the developing central nervous system, its function remains to be determined. In this study, we show that NDPK-D knockdown induces apoptosis in neuroblastoma cells as well as in mouse cortex, suggesting that NDPK-D is required for neuronal survival. We identified NDPK-D as a binding partner of NAD+-dependent histone deacetylase, SIRT1, by yeast two-hybrid screening. NDPK-D co-localized with SIRT1, and the association of these molecules was confirmed by co-immunoprecipitation. Inhibition of SIRT1 increases the acetylation of NDPK-D. Overexpression of NDPK-D along with SIRT1, or mutation in the acetylated lysine residues in NDPK-D, increases its nuclear accumulation. Furthermore, the NDPK-D acetylation-mimic mutant increased apoptosis in N1E-115 cells. Our data demonstrate that acetylation regulates the shuttling of NDPK-D between nucleus and cytoplasm, and increased acetylation of NDPK-D causes apoptosis.
