Serum iron levels increased by cancer chemotherapy correlate the chemotherapy-induced nausea and vomiting.

Background: The pathogenesis of chemotherapy-induced nausea and vomiting (CINV) is not fully elucidated. We hypothesized that serum iron levels may be associated with CINV because symptoms of iron poisoning resemble the adverse effects of chemotherapy.

Methods: Patients with lung cancer undergoing chemotherapy were included in this retrospective study where serum iron level, unsaturated iron-binding capacity (UIBC), total iron-binding capacity, and ferritin were available prior to and on days 2 and 8 of chemotherapy.

[Nearly Complete Response after Second-Line Therapy with Nab-Paclitaxel Monotherapy in a Patient with Recurrent Advanced Non-Small Cell Lung Cancer].

A 62-year-old woman was diagnosed with stage IV lung adenocarcinoma. After resection of a metastatic brain tumor, she had received first-line chemotherapy consisting of 6 courses of carboplatin and pemetrexed, then 14 courses of maintenance therapy of pemetrexed until disease progression. As second-line treatment, she was administered nanoparticle albuminbound paclitaxel(nab-paclitaxel)monotherapy.

Efficacy of triple antiemetic therapy (palonosetron, dexamethasone, aprepitant) for chemotherapy-induced nausea and vomiting in patients receiving carboplatin-based, moderately emetogenic chemotherapy.

Background: Chemotherapy-induced nausea and vomiting (CINV) is a major adverse toxicity of cancer chemotherapy. Recommended treatments for prevention of CINV vary among published guidelines, and optimal care for CINV caused by moderately emetogenic chemotherapy has not been established. This study assessed the efficacy and safety of triple antiemetic therapy comprising palonosetron, dexamethasone and aprepitant for carboplatin-based chemotherapy.

Nintedanib modulates surfactant protein-D expression in A549 human lung epithelial cells via the c-Jun N-terminal kinase-activator protein-1 pathway.

Idiopathic pulmonary fibrosis (IPF) is a progressive disease with a high mortality rate. Signalling pathways activated by several tyrosine kinase receptors are known to be involved in lung fibrosis, and this knowledge has led to the development of the triple tyrosine kinase inhibitor nintedanib, an inhibitor of vascular endothelial growth factor receptor (VEGFR), platelet-derived growth factor receptor (PDGFR), and fibroblast growth factor receptor (FGFR), for the treatment of IPF. Pulmonary surfactant protein D (SP-D), an important biomarker of IPF, reportedly attenuates bleomycin-induced pulmonary fibrosis in mice.

Delayed elimination of SN-38 in cancer patients with severe renal failure.

This prospective study is designed to examine the effects of severe renal failure on the pharmacokinetics of irinotecan. The pharmacokinetics of irinotecan, 7-ethyl-10-hydroxycamptothecin (SN-38), and SN-38 glucuronide (SN-38G) in three cancer patients with severe renal failure [creatinine clearance (Ccr) ≤ 20 ml/min] who were undergoing dialysis and received 100 mg/m(2) irinotecan as monotherapy were prospectively compared with those in five cancer patients with normal renal function (Ccr ≥ 60 ml/min). To ensure that the subjects had similar genetic backgrounds of UDP-glucuronosyltransferase (UGT) 1A1, patients with UGT1A1*1/*1, *1/*6, or *1/*28 were enrolled.

Phase I/II study of FOLFIRI in Japanese patients with advanced colorectal cancer.

Objective: This phase I/II study determined the recommended dose of FOLFIRI (irinotecan, infusional 5-fluorouracil and leucovorin) for Japanese patients with advanced colorectal cancer, and evaluated safety at the recommended dose in patients without the UDP-glucuronosyltransferase 1A1*28 allele which caused reduced enzyme expression.

Methods: The phase I part assessed the maximum tolerated dose of FOLFIRI to determine the recommended doses of irinotecan and infusional 5-fluorouracil. The doses were escalated from 150 to 180 mg/m(2) (irinotecan) and 2000 to 2400 mg/m(2) (5-fluorouracil).

UGT1A1*1/*28 and *1/*6 genotypes have no effects on the efficacy and toxicity of FOLFIRI in Japanese patients with advanced colorectal cancer.

Purpose: Differences in efficacy and toxicity between UDP-glucuronosyltransferase (UGT) 1A1*1/*1 and *1/*6 or *1/*28 genotypes remain unclear in Japanese patients.

Methods: Patients with advanced colorectal cancer who received irinotecan combined with 5-fluorouracil plus l-leucovorin (FOLFIRI) as first-line therapy were divided into two groups: those with UGT1A1*1/*1 genotype and those with UGT1A1*1/*6 or *1/*28 genotype. Efficacy and toxicity were compared between these groups retrospectively.

Association of UGT2B7 and ABCB1 genotypes with morphine-induced adverse drug reactions in Japanese patients with cancer.

Purpose: To investigate the effects of genetic polymorphisms on morphine-induced adverse events in cancer patients.

Methods: We examined the relation of morphine-related adverse events to polymorphisms in UDP-glucuronosyltransferase (UGT) 2B7, ATP-binding cassette, sub-family B, number 1 (ABCB1), and μ-opioid receptor 1 genes in 32 Japanese cancer patients receiving oral controlled-release morphine sulfate tablets.

Results: The T/T genotype at 1236 or TT/TT diplotype at 2677 and 3435 in ABCB1 was associated with significantly lower frequency of fatigue (grades 1-3) (P = 0.

Association of ATP-binding cassette, sub-family C, number 2 (ABCC2) genotype with pharmacokinetics of irinotecan in Japanese patients with metastatic colorectal cancer treated with irinotecan plus infusional 5-fluorouracil/leucovorin (FOLFIRI).

ATP-binding cassette, sub-family C, number 2 (ABCC2) is involved in the biliary excretion of irinotecan and its metabolites, SN-38 and SN-38 glucuronide. Effects of the ABCC2 genotype on the pharmacokinetics (PK) of irinotecan and the metabolites were examined in Japanese patients with metastatic colorectal cancer receiving irinotecan plus infusional 5-fluorouracil/leucovorin (FOLFIRI). ABCC2 genotypes (-1549G>A, -1023G>A, -1019A>G, -24C>T, 1249G>A and 3972C>T) and haplotypes were analyzed for 67 patients with cancer.

CYP2A6 and the plasma level of 5-chloro-2, 4-dihydroxypyridine are determinants of the pharmacokinetic variability of tegafur and 5-fluorouracil, respectively, in Japanese patients with cancer given S-1.

S-1 is an oral anticancer agent composed of tegafur (FT), 5-chloro-2,4-dihydroxypyridine (CDHP), and potassium oxonate. CDHP is added to prevent degradation of 5-fluorouracil (5-FU) by inhibiting dihydropyrimidine dehydrogenase. CYP2A6 is involved in the biotransformation of FT to 5-FU.

A case of respiratory akathisia in a cancer patient: a case report.

Objective: It has been reported that akathisia is a neurological side effect induced by antiemetic drugs and/or antipsychotics. Akathisia can occur in any area of the body, but respiratory akathisia is an unusual type of akathisia. Cases of respiratory akathisia in cancer patients taking antiemetic drugs have not previously been reported.

Detection and treatment of akathisia in advanced cancer patients during adjuvant analgesic therapy with tricyclic antidepressants: case reports and review of the literature.

Objective: There is substantial evidence that tricyclic antidepressants are effective in the management of chronic pain, including cancer pain. In oncological settings, these agents are used as adjuvant analgesic drugs. However, cases of akathisia due to tricyclic antidepressants used as adjuvant analgesic therapy have not previously been reported.

Genetic linkage of UGT1A7 and UGT1A9 polymorphisms to UGT1A1*6 is associated with reduced activity for SN-38 in Japanese patients with cancer.

Purpose: The phenotypic effects of UGT1A7 and UGT1A9 genetic polymorphisms on the in vivo pharmacokinetics of irinotecan were examined.

Methods: Eighty-four Japanese patients with cancer who received irinotecan-based chemotherapy were enrolled. Polymorphisms present in UGT1A7 (T to G transversion at -57 and UGT1A7*2 to *9), UGT1A9 (9 or 10 repeat of T at -118 [-118(T)9 or 10] and UGT1A9*2 to *5), and UGT1A1 (UGT1A1*6, UGT1A1*27, and UGT1A1*28) were analyzed for all patients.

Pharmacogenetic impact of polymorphisms in the coding region of the UGT1A1 gene on SN-38 glucuronidation in Japanese patients with cancer.

Pharmacogenetic testing for UDP-glucuronosyltransferase (UGT) 1A1*28, a promoter variant of the UGT1A1 gene, is now carried out clinically to estimate the risk of irinotecan-associated toxicity. We studied the clinical significance of UGT1A1*6 and UGT1A1*27, two variants in exon 1 of the UGT1A1 gene that are found mainly in Asians. The study group comprised 46 Japanese patients who received various regimens of chemotherapy including irinotecan at doses from 50 to 180 mg/m(2).

Novel single nucleotide polymorphism of UGT1A9 gene in Japanese.

We sequenced from 5'-franking region to intron 1 (to 337 bp downstream from exon 1) of the UDP-glucuronosyltransferase (UGT) 1A9 gene prepared from 55 Japanese cancer patients. Seven single nucleotide polymorphisms (SNPs) were found. Two of them were UGT1A9 -118(T)n (n=10) and UGT1A9*5, and four were reported SNPs in intron 1 of UGT1A9 gene (89540C>T, 89549G>A, 89616T>A and 89710A>C).

Novel single nucleotide polymorphism of UGT1A7 gene in Japanese.

We sequenced exon 1 of the UDP-glucuronosyltransferase (UGT) 1A7 gene from 52 Japanese cancer patients. Four single nucleotide polymorphisms (SNPs) were found. Three of them caused UGT1A7*2 and UGT1A7*3.

Gefitinib (Iressa) inhibits the CYP3A4-mediated formation of 7-ethyl-10-(4-amino-1-piperidino)carbonyloxycamptothecin but activates that of 7-ethyl-10-[4-N-(5-aminopentanoic acid)-1-piperidino]carbonyloxycamptothecin from irinotecan.

Gefitinib (Iressa) is an anticancer drug that selectively inhibits tyrosine kinases of epidermal growth factor receptor. Gefitinib might affect CYP3A4-mediated metabolism, since the drug is a substrate of human CYP3A. In this study, we evaluated the effects of gefitinib on drug metabolism catalyzed by human CYP3A4.

Prognosis of 6644 resected non-small cell lung cancers in Japan: a Japanese lung cancer registry study.

For the scheduled future revision of the TNM staging system for lung cancer, it is important that the present 1997 version be evaluated in a large population. In 2001, the Japanese Joint Committee of Lung Cancer Registry sent a questionnaire to 320 Japanese institutions regarding the prognosis and clinicopathological profiles of patients who underwent the resection for primary lung neoplasms in 1994. We compiled the data for 7408 patients from 303 institutions (94.
