Objective: Recent data indicated that concurrent chemoradiotherapy (CCRT) using high dose cisplatin (CDDP) is the most useful treatment for advanced head and neck squamous cell carcinoma (SCC). Regarding the dose of CDDP, 100mg/m is most recommended in Western countries. However, in terms of a balance of efficacy and adverse events, appropriate dose of cytotoxic drugs such as CDDP may be different among the different ethnic groups. In this multicenter phase I/II study, we aimed to identify the optimal dose of CDDP in CCRT for patients with advanced head and neck SCC in the Japanese.
Methods: Patients were eligible for inclusion if they had head and neck SCC that was treated with radical CCRT comprising whole-neck irradiation of the primary lesion and level II-IV lymph nodes on both sides. For the phase I study, a CDDP dose was 70mg/m for level 0, 80mg/m for level 1, and 100mg/m for level 2. Maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) were examined by phase I trial, by which CDDP dose for phase II was determined. The primary endpoint for the phase II was CCRT completion rate, and the secondary endpoint was full-dose-CCRT completion rate, the percentage of patients receiving a total CDDP dose of ≥200mg/m, response rate, and incidences of adverse events.
Results: A CDDP dose of 100mg/m was the MTD for phase I, and the recommended dose for phase II was 80 mg/m. Forty-seven patients were evaluated in the phase II trial. CCRT completion rate, full-dose-CCRT rate, and the percentage of patients receiving a total CDDP dose of ≥200mg/m, were 93.6%, 78.7%, and 93.6%, respectively. One patient (2.1%) developed grade 2 renal dysfunction, and no patient developed febrile neutropenia or a grade 4 adverse event.
Conclusion: The present phase I study indicated that a CDDP dose of 80mg/m is the optimal dose in terms of safety. The phase II study revealed that CCRT completion rate, response rate, and rates of adverse events were not inferior for a CDDP dose of 80mg/m as compared with a dose of 100mg/m, and a dose of 80mg/m is therefore recommended in CCRT for the Japanese. This study was registered with the University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR; identification No. UMIN000010369).

Advanced ovarian cancer often presents with multiple lesions exhibiting varying responses to chemotherapy, highlighting the critical influence of the tumor microenvironment (TME). This study investigates the phenomenon of chemotherapeutic hormesis, wherein low doses of chemotherapeutic agents, such as cisplatin (CDDP) and paclitaxel (PTX), paradoxically stimulate rather than inhibit cancer cell proliferation. Our findings indicate that NOS3 ovarian cancer cells, particularly drug-resistant variants, exhibit enhanced proliferation when exposed to low concentrations of these drugs.

Background: Chinese yam polysaccharide (SYDT) has been reported to protect renal function and mitigate renal fibrosis in mice with diabetic nephropathy. Based on a multi-omics analysis, the objectives of this study were to determine the effect of SYDT on cisplatin (CDDP)-induced chronic renal interstitial fibrosis (RIF) and the underlying molecular mechanisms using an in vivo model.
Methods: Rats were intraperitoneally injected with a single dose of CDDP and then treated with SYDT or amifostine (AMF).

Background: Gemcitabine (GEM) and cisplatin (CDDP) combination therapy (GC therapy) is the standard 1st-line regimen for incurable biliary tract cancers (BTCs). However, the correlation between dynamic changes in renal function and the outcomes of GC therapy remains unclear. This study aimed to clarify the association between renal function alterations and treatment outcomes after GC therapy.

Background/aim: The therapeutic efficacy of the paclitaxel (PTX) + cetuximab (Cmab) combination regimen was investigated in patients with recurrence or metastasis after superselective intraarterial chemoradiotherapy (SSIACRT) for oral cancer, and the safety was retrospectively examined.
Patients And Methods: All enrolled patients with advanced oral cancer or who had refused surgery over 10 years from December 2012 to December 2022 underwent SSIACRT for 6 to 9 weeks [cisplatin (CDDP): total 160-630 mg/m and radiotherapy: total 50-70 Gy]. Nine cases (tongue cancer, maxillary gingival cancer, and mandibular gingival cancer; three cases each) were subjected to PTX + Cmab therapy.
