ABSTRACT
Although carboplatin (CBDCA) is classified as a moderately emetogenic agent, the majority of guidelines recommend the use of a neurokinin-1 receptor antagonist in addition to a 5-hydroxytryptamine type 3 receptor antagonist with dexamethasone (DEX) for CBDCA-containing chemotherapy because of its higher emetogenic risk. However, the additional efficacy of aprepitant (APR) in CBDCA-containing treatment remains controversial, and data on multiple-day treatments are limited. Etoposide (ETP) was administered on days 1-3 in the CBDCA + ETP regimen, and it is important to evaluate suitable antiemetic therapy for the regimen. Therefore, we evaluated the efficacy of additional APR in CBDCA + ETP. Patients were divided into two groups and retrospectively evaluated. One was the control group, which was prophylactically administered palonosetron (PALO) and DEX, and the other was the APR group, which received APR orally with PALO and DEX. The primary endpoint was complete response (CR) between the groups. The overall CR rates were 75.0 and 76.4% in the control and APR groups, respectively, with no significant difference (p = 1.00). In the acute phase, it was 88.9 and 97.2%, respectively, and 86.1 and 79.2% in the delayed phase, respectively, without significant differences (p = 0.10 and 0.38, respectively). The incidence and severity of nausea, vomiting, and anorexia were not significantly different between the two groups in the acute and delayed phases. Our findings suggest that combining APR with PALO and DEX does not improve the CR rate in CBDCA + ETP therapy.

Background: Olfactory neuroblastoma (ONB) is a rare malignant tumor arising from the olfactory neuroepithelium. The standard of care for ONB is surgical resection; however, detailed treatment protocols vary by institution. Our treatment protocol consists of endoscopic skull base surgery (ESBS) for endoscopically resectable cases and induction chemotherapy followed by craniotomy combined with ESBS for locally advanced cases, with postoperative radiotherapy performed for all cases. Chemoradiotherapy (CRT) is performed in unresectable cases. In this study, we evaluate our treatment protocol and outcomes for ONB. Methods: A retrospective review of patients with ONB was conducted. Outcomes included survival outcomes and perioperative data. Results: Fifteen patients (53.6%) underwent ESBS, 12 (42.9%) underwent craniotomy combined with ESBS, and 1 (3.6%) received CRT. The 5- and 10-year overall survival rates for all patients were 92.9% and 82.5%, respectively, with a median follow-up period of 81 months. The 5- and 10-year disease-free survival rates were 77.3% and 70.3%, respectively, and the 5- and 10-year local control rates were 88.2% and 80.2%, respectively. Patients undergoing ESBS demonstrated a significantly shorter operating time, period from operation to ambulation, hospitalization period, and less blood loss than those undergoing craniotomy combined with ESBS. Conclusion: Our treatment protocol was found to afford favorable outcomes. Patients who underwent endoscopic resection showed lower complication rates and better perioperative data than those who underwent craniotomy combined with ESBS. With appropriate case selection, ESBS is considered a useful approach for ONB.
ABSTRACT
OBJECTIVE: Irinotecan (IRI) is an anticancer drug that is frequently used to treat colorectal, gastric, and pancreatic cancers. Its side effects include cholinergic symptoms, such as diarrhea, abdominal pain, nausea, and hyperhidrosis. Anticholinergic medicines are frequently used for treatment or prophylaxis; however, the risk factors for the failure of a single prophylactic anticholinergic administration remain unclear. Moreover, an appropriate anticholinergic drug for prophylaxis remains unknown. Thus, we aimed to identify the risk factors associated with the failure of a single prophylactic dose of anticholinergic drugs for IRI-induced cholinergic symptoms and to evaluate the usefulness of multiple prophylactic doses of anticholinergic drugs. MATERIALS AND METHODS: Patients who underwent IRI treatment for colorectal, gastric, or pancreatic cancer and received prophylactic anticholinergic drugs for IRI-induced cholinergic symptoms (n = 135) were retrospectively evaluated. Univariate and multivariate logistic regression analyses were performed to identify the risk factors for failure of a single prophylactic dose of anticholinergic drugs. We also evaluated the efficacy of multiple prophylactic anticholinergic drug administration. RESULTS: Based on univariate and multivariate analyses, colorectal cancer, female sex, and prophylactic use of scopolamine butyl bromide were identified as risk factors for failure of a single prophylactic dose of anticholinergic drugs. The efficacy of multiple prophylactic doses was confirmed to be 95% of the patients who had a single prophylactic failure due to temporary effect but symptom appearance after a certain period of time (wearing-off). CONCLUSION: We determined that colorectal cancer, female sex, and prophylactic use of scopolamine butyl bromide were risk factors associated with the failure of a single prophylactic dose of anticholinergic drugs, and that multiple prophylactic doses for wearing-off can be a promising method.

BACKGROUND/AIM: Cisplatin-induced nephrotoxicity (CIN) is one of the most attention-requiring adverse effects. We have reported that diabetes mellitus significantly increases the incidence of CIN in a short hydration method in real-world lung cancer treatment. However, the effect of prediabetes on CIN development remains unclear. This study investigated whether patients with prediabetes exhibit CIN at a greater rate during real-world cisplatin-including treatments as a subgroup analysis. PATIENTS AND METHODS: This retrospective observational study enrolled patients with lung cancer receiving cisplatin treatment (≥75 mg/m2) from May 2014 to January 2021 (n=169). Patients were divided into a prediabetes group (baseline HbA1c 5.7-6.4%) and a control group (baseline HbA1c <5.7%). The primary endpoint of this study was the incidence of CIN in all treatment cycles between the two groups. We also assessed variations in serum creatinine (SCr) levels and creatinine clearance (CCr). RESULTS: CIN occurred in 4.7% of controls and 8.3% of patients with prediabetes in all cycles, with no significant difference (p=0.37). In contrast, variation of SCr levels and CCr was significantly worse in the prediabetes group [median variation level (range) 0.11 mg/dl (-0.11-0.46 mg/dl) and 0.12 mg/dl (-0.02-1.08 mg/d) in controls and prediabetes, p=0.04 for SCr; -12.9 ml/min (-54.1-4.9 ml/min) and -16.3 ml/min (-49.4-3.0 ml/min), p=0.02 for CCr, respectively]. These results were also confirmed during the first cycle of treatment. CONCLUSION: Patients with prediabetes did not develop problematic CIN, although they exhibited significant increases in SCr and decreases in CCr.

Background: BRAF V600 mutations are common in melanoma, thyroid, and non-small-cell lung cancers. Despite dabrafenib and trametinib being standard treatments for certain cancers, their efficacy across various solid tumours remains unelucidated. The BELIEVE trial assessed the efficacy of dabrafenib and trametinib in solid tumours with BRAF V600E/R or non-V600 BRAF mutations. Methods: Between October 1, 2019, and June 2022, at least 50 patients with measurable and seven without measurable diseases examined were enrolled in a subcohort of the BELIEVE trial (NCCH1901, jRCTs031190104). BRAF mutated solid tumour cases other than BRAF V600E mutated colorectal cancer, melanoma, and non-small cell lung cancer cases were included. Patients with solid tumours received dabrafenib (150 mg) twice daily and trametinib (2 mg) once daily until disease progression or intolerable toxicity was observed. The primary endpoint was overall response rate (ORR), and secondary endpoints included progression-free survival (PFS), 6-month PFS, and overall survival (OS). Bayesian analysis was performed using a prior distribution with a 30% expected response rate [Beta (0.6, 1.4)]. Findings: Fourty-seven patients with measurable disease, mainly with the BRAF V600E mutation (94%), and three others with non-V600E BRAF mutations (V600R, G466A, and N486_P490del) were enrolled. The primary sites included the thyroid gland, central nervous system, liver, bile ducts, colorectum, and pancreas. The confirmed ORR was 28.0%; the expected value of posterior distribution [Beta (14.6, 37.4)] was 28.1%, although the primary endpoint was achieved, not exceeding an unexpectedly high response rate of 60% obtained using Bayesian analysis. The disease control rate (DCR) was 84.0%. The median PFS was 6.5 months (95% confidence interval [CI]; 4.2-7.2 months, 87.8% at 6 months). Responses were observed across seven tumour types. Median OS was 9.7 months (95% CI, 7.5-12.2 months). Additional patients without measurable diseases had a median PFS of 4.5 months. Adverse events (AEs) were consistent with previous reports, with 45.6% of patients experiencing grade ≥3 AEs. Interpretation: This study reported promising efficacy against BRAF V600-mutant tumours. Dabrafenib and trametinib would offer a new therapeutic option for rare cancers, such as high-grade gliomas, biliary tract cancer, and thyroid cancer. Funding: This study was funded by the Japan Agency for Medical Research and Development (22ck0106622h0003) and a Health and Labour Sciences Research Grant (19EA1008).
ABSTRACT
BACKGROUND: HER2-expressing salivary gland carcinoma (SGC) is associated with poor prognosis. Trastuzumab deruxtecan (T-DXd, DS-8201) has shown evidence of antitumor activity for several HER2-expressing solid tumors in multiple studies. This study aimed to present the efficacy and safety of T-DXd in patients with HER2-expressing SGC from a pooled analysis. METHODS: Patients with HER2-expressing SGC were pooled from two phase I, open-label studies of T-DXd: a two-phase, multiple-dose, first-in-human study (NCT02564900) and a single-sequence crossover drug-drug interaction study (NCT03383692). Endpoints included efficacy (objective response rate [ORR], duration of response [DoR] and progression-free survival [PFS]) and safety. RESULTS: This pooled analysis included 17 patients with SGC (median age: 57 years; male: 88.2%); median (range) follow-up duration was 12.0 (2.3-|34.8) months. Among these patients, 14 had received prior HER2-targeted agents and 13 had undergone prior radiotherapy. The investigator-assessed confirmed ORR was 58.8% (95% confidence interval [CI], 32.9-|81.6). The median (95% CI) DoR and PFS were 17.6 months (4.0 to not evaluable [NE]) and 20.5 months (11.1-NE), respectively. All 17 patients reported treatment-emergent adverse events (TEAEs); 76.5% reported TEAEs of grade ≥3. The most common TEAEs were decreased appetite (94.1%), nausea (88.2%) and neutrophil count decreased (76.5%). Of the 17 patients, five (29.4%) reported adjudicated drug-related interstitial lung disease (grade 1, n = 3; grade 2, n =1; grade 3, n = 1). CONCLUSION: The results of this pooled analysis provide evidence that clinical benefit is achievable with T-DXd in patients with HER2-expressing SGC.

Recent results show that polymorphisms of programmed death ligand 1 (PD-L1, also known as CD274 or B7-H1) might be used as a possible marker for effectiveness of chemotherapy and cancer risk. However, the effect of PD-L1 gene variations on PD-L1 expression remain unclear. Given the post-transcriptional machinery in tumor PD-L1 expression, we investigated single nucleotide polymorphisms (SNPs) in the 3'-untranslated region (3'-UTR) of the PD-L1 gene, rs4143815 and rs4742098, using formalin-fixed paraffin-embedded sections of 154 patients with non-small cell lung cancers (NSCLCs). In rs4143815, the GG genotype showed significant association with PD-L1 expression (P = 0.032). In rs4742098, the AA genotype was significantly associated with histology and PD-L1 expression (P = 0.022 and P = 0.008, respectively). In multivariate logistic regression analysis, the AA genotype in rs4742098 was correlated with PD-L1 expression (odds ratio 0.408, P = 0.048). Interestingly, approximately 10% of the NSCLC cases showed somatic mutation when we compared genotypes of these SNPs between NSCLC tissues and non-tumor tissues from the same patients. In addition, cases with somatic mutation showed higher levels of PD-L1 expression than cases with germline mutation in rs4143815 GG. In conclusion, we demonstrated that the rs4143815 and rs4742098 SNPs in the 3'-UTR of PD-L1 were associated with tumor PD-L1 expression in NSCLCs.

A 26-year-old man presented with a tumor in the left soleus muscle. The tumor was diagnosed as a locally advanced leiomyosarcoma. The patient was treated with irradiation followed by wide resection. One year after surgery, the patient presented with multiple lung metastases. Despite aggressive sequential chemotherapy, systemic metastatic tumors continued to develop. To explore therapeutic options for the patient, we performed DNA-based CGP with FoundationOne® CDx (F1). F1 identified an out-of-strand rearrangement of the NOS1AP::NTRK1 gene, which has not been previously reported. In contrast, RNA sequencing revealed an in-frame LMNA::NTRK1 gene, which is an oncogenic fusion gene.
