Tumor response to irinotecan is associated with CYP3A5 expression in colorectal cancer.

Tumor response to irinotecan is associated with CYP3A5 expression in colorectal cancer. Oncol Lett. 2019 Apr;17(4):3890-3898 Authors: Buck E, Sprick M, Gaida MM, Grüllich C, Weber TF, Herpel E, Bruckner T, Koschny R Abstract Recently, a tumor-autonomous cytochrome P450 (CYP)-3A5-mediated resistance to cancer therapy has been demonstrated in pancreatic ductal adenocarcinoma. Expression of CYP3A5, which is involved in the degradation of irinotecan, has also been reported in colorectal cancer (CRC). The aim of the present study was to analyze CYP3A5 expression in the normal colon, colon adenoma, CRC and normal tissues, as well as to examine whether CYP3A5 expression in CRC has an impact on tumor response to irinotecan treatment. Immunohistochemistry was used to assess 85 tissue samples from 65 patients with CRC, along with 15 samples of normal colon and 45 samples of colon adenoma (including tubular, tubulovillous, and sessile serrated adenomas), and a tissue microarray (TMA) comprised of 26 different normal tissue types. Expression of CYP3A5 was evaluated with a semi-quantitative score. Tumor response to irinotecan therapy was assessed according to the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 guidelines. In normal tissues, CYP3A5 was expressed in epithelial cells of the colon, gallbladder, kidney, liver, small intestine, stomach, thyroid gland and tonsil, as well as in nerves. Expression in colon mucosa was heterogeneous, with only wea...

Background: The circadian timing system or circadian clock plays a crucial role in many biological processes, such as the sleep-wake cycle, hormone secretion, cardiovascular health, glucose homeostasis, and body temperature regulation. Energy balance is also one of the most important cornerstones of metabolic processes, whereas energy imbalance is associated with many diseases (i.e., obesity, diabetes, cardiovascular disease). Circadian clock is the main regulator of metabolism, and this analysis provides an overview of the bidirectional effect of circadian rhythm on metabolic processes and energy balance.Summary: The circ...

In conclusion, the present study suggests that the preoperative CONUT score was associated with an increased risk of mortality and complications in GI and HPB surgical oncology. Patients with higher CONUT score as compared with those having a lower score had approximately a fivefold mortality risk and an increased risk up to 55% on major and overall complications after GI and HPB surgery. Our analysis indicates that the appropriate cutoff value of the CONUT score to predict postoperative major complications would be between 4 and 5. The preoperative evaluation of the CONUT score would be helpful for predicting the risk of ...

We report an extremely rare case of a right ventricular outflow tract mass identified to be an intracardiac MC in a 4-month-old male infant. Pathology revealed an EWS-KLF15 translocation. Treatment included gross total resection and intensive chemotherapy. Recurrent cardiac mass with brain metastasis was seen 16 months after primary diagnosis. We describe the rarity of intracardiac MC in pediatric patients and the challenges encountered in the multimodal management of this patient.

Successful use of immune checkpoint inhibitors in a variety of cancers has generated interest in using this approach in pediatric brain tumors. We performed a retrospective review of 10 consecutive children (6 boys, 4 girls; ages, 2 to 17 y), with recurrent or refractory pediatric brain tumors (5 high-grade glioma, 1 low-grade glioma, pineoblastoma, medulloblastoma, ependymoma, and CNS embryonal tumor, NOS) treated at Rady Children’s Hospital San Diego from 2015 to 2017 with the immune checkpoint inhibitor nivolumab (3 mg/kg every 2 wk). Eight of 10 patients received prior chemotherapy and 9 radi...

We report 2 cases of intravenous immunoglobulin refractory ITP in children receiving chemotherapy for high-risk neuroblastoma. ITP was successfully treated with the thrombopoietin-receptor-agonist romiplostim, allowing safe and timely continuation of antineuroblastoma therapies in these high-risk patients.
