RESUMO

BACKGROUND: In older patients, esophageal squamous cell carcinoma (ESCC) is difficult to treat using standard therapies, including surgery and cisplatin-based chemoradiotherapy. Paclitaxel (PTX) has radiosensitizing activity. We conducted a phase I trial of PTX combined with radiotherapy to establish a standard therapy for locally advanced ESCC in older patients. METHODS: Enrollment was conducted at six centers in Japan from April 2016 to September 2019. The participants were aged ≥ 70 years, had locally advanced ESCC, and were intolerant to surgery or unwilling. A fixed 60-Gy radiation dose was administered in 30 fractions. PTX dosing levels started at 30 mg/m2 weekly for 6 weeks. Depending on the number of DLTs, the dose was set to be increased by 10 mg/m2 or switched to biweekly. A geriatric assessment was performed before treatment using the Geriatric-8 screening tool. The primary endpoint was dose-limiting toxicity (DLT). RESULTS: We enrolled 24 patients (6 per group); DLT was observed in one (grade 4 hypokalemia), one (grade 3 aspiration), two (grade 3 radiodermatitis, grade 3 esophageal hemorrhage), and two (grade 3 anorexia, grade 5 pneumonitis) patients in the weekly PTX 30, 40, 50, and 60 mg/m2 groups, respectively. All adverse events, except death in the 60 mg/m2 group, showed reversible improvement, and the safety profile was considered acceptable. The 2-year survival and complete response rates were 40.0% and 54.2%, respectively. There was a significant difference in survival between favorable and unfavorable Geriatric-8 scores. CONCLUSIONS: The recommended PTX dose with concomitant radiation was determined to be 50 mg/m2 weekly. Phase II trials at this dose are underway.

RESUMO

BACKGROUND: The Japan Society of Clinical Oncology Clinical Practice Guidelines for Antiemesis 2023 was extensively revised to reflect the latest advances in antineoplastic agents, antiemetics, and antineoplastic regimens. This update provides new evidence on the efficacy of antiemetic regimens. METHODS: Guided by the Minds Clinical Practice Guideline Development Manual of 2017, a rigorous approach was used to update the guidelines; a thorough literature search was conducted from January 1, 1990, to December 31, 2020. RESULTS: Comprehensive process resulted in the creation of 13 background questions (BQs), 12 clinical questions (CQs), and three future research questions (FQs). Moreover, the emetic risk classification was also updated. CONCLUSIONS: The primary goal of the present guidelines is to provide comprehensive information and facilitate informed decision-making, regarding antiemetic therapy, for both patients and healthcare providers.

RESUMO

BACKGROUND: Anticipatory chemotherapy-induced nausea and vomiting (CINV) is a conditioned response influenced by the severity and duration of previous emetic responses to chemotherapy. We aimed to evaluate the efficacy of non-pharmacologic interventions for anticipatory CINV among patients with cancer. METHODS: We conducted a systematic search in databases, including PubMed, the Cochrane Library, CINAHL, and Ichushi-Web, from January 1, 1990, to December 31, 2020. Randomized controlled trials, non-randomized designs, observational studies, or case-control studies that utilized non-pharmacological therapies were included. The primary outcomes were anticipatory CINV, with an additional investigation into adverse events and the costs of therapies. The risk-of-bias for each study was assessed using the Cochrane risk-of-bias tool, and meta-analysis was performed using Revman 5.4 software. RESULTS: Of the 107 studies identified, six met the inclusion criteria. Three types of non-pharmacological treatments were identified: systematic desensitization (n = 2), hypnotherapy (n = 2), and yoga therapy (n = 2). Among them, systematic desensitization significantly improved anticipatory CINV as compared to that in the control group (nausea: risk ratio [RR] = 0.60, 95% confidence interval [CI] = 0.49-0.72, p < 0.00001; vomiting: RR = 0.54, 95% CI = 0.32-0.91, p = 0.02). However, heterogeneity in outcome measures precluded meta-analysis for hypnotherapy and yoga. Additionally, most selected studies had a high or unclear risk of bias, and adverse events were not consistently reported. CONCLUSIONS: Our findings suggest that systematic desensitization may effectively reduce anticipatory CINV. However, further research is warranted before implementation in clinical settings.
