What You Need to Know Before You Apply

What is the purpose of this trial?

This trial examines how different doses of the chemotherapy drug cisplatin, combined with radiotherapy, affect head and neck cancer. Researchers aim to determine whether a high dose or a low dose of cisplatin is more effective for these cancers. The trial includes participants with specific types of head and neck cancer, such as those in the mouth or throat, who have not received cancer treatments in the past five years. Participants should be able to tolerate the treatments and plan to complete a full course of radiotherapy. As an unphased trial, this study provides patients the opportunity to contribute to important research that could enhance future cancer treatments.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that both high-dose and low-dose cisplatin treat head and neck cancer, each with different safety profiles. High-dose cisplatin often causes significant side effects, with more than 75% of patients experiencing serious issues, especially with a three-week dosing schedule. Despite these challenges, the treatment remains effective.

In contrast, low-dose weekly cisplatin is less harmful, typically causing fewer severe side effects than the high-dose regimen. This makes it a popular choice for those concerned about the stronger effects of high-dose treatments.

While both treatments are effective, considering potential side effects and discussing them with a healthcare provider is important.¹ ² ³ ⁴ ⁵

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments because they explore different dosing strategies of cisplatin combined with radiotherapy for head and neck cancer. Unlike the standard high-dose approach, the study is comparing both high-dose and low-dose regimens. The low-dose option, given weekly, could potentially reduce side effects and improve patient tolerance without compromising effectiveness. This investigation aims to find a more manageable and equally effective treatment option for patients, offering a new angle on how to balance efficacy with quality of life.

What evidence suggests that this trial's treatments could be effective for head and neck cancer?

This trial will compare the effectiveness of high-dose versus low-dose cisplatin combined with radiotherapy for treating head and neck cancer. Research has shown that both high-dose and low-dose cisplatin, when paired with radiotherapy, effectively treat this cancer type. Participants in one arm of the trial will receive high-dose cisplatin, a common treatment that works well with radiotherapy, improving survival rates for patients with advanced cancer in this area. Participants in another arm will receive low-dose cisplatin, administered more frequently, which also leads to good survival outcomes and generally causes fewer side effects, such as less hearing loss, compared to high-dose treatments. Both options offer similar benefits, but low-dose cisplatin might be preferable for those concerned about side effects.¹ ² ³ ⁶ ⁷

Published Research Related to This Trial

The addition of low-dose cisplatin (CDDP) to hyperfractionated radiation therapy (Hfx RT) significantly improved survival rates in patients with locally advanced squamous cell carcinoma of the head and neck, with 68% survival at 2 years compared to 49% with Hfx RT alone.

Despite the survival benefits, the combination treatment did not increase the incidence of severe radiation-induced toxicity compared to Hfx RT alone, although higher rates of hematologic toxicity were observed in patients receiving CDDP.

Hyperfractionated radiation therapy with or without concurrent low-dose daily cisplatin in locally advanced squamous cell carcinoma of the head and neck: a prospective randomized trial.Jeremic, B., Shibamoto, Y., Milicic, B., et al.[2022]

In a study involving 225 patients with locally advanced head and neck squamous cell cancer, both high-dose cisplatin and a weekly cisplatin-paclitaxel regimen showed similar complete response rates of 88%.

The weekly cisplatin-paclitaxel regimen resulted in significantly lower acute and chronic toxicities compared to high-dose cisplatin, making it a safer alternative for patients who cannot tolerate cisplatin.

Comparing high-dose cisplatin with cisplatin-based combination chemotherapy in definitive concurrent chemoradiation setting for locally advanced head and neck squamous cell carcinoma (LAHNSCC).Furqan, M., Snyders, TP., Saqlain, MU., et al.[2021]

In a randomized trial involving 64 patients with advanced head and neck squamous carcinoma, both high-dose (120 mg/m2) and low-dose (60 mg/m2) cisplatin showed similar response rates of 16.1% and 17.8%, respectively.

The study found no significant difference in survival rates between the two dosage groups, indicating that increasing the dose of cisplatin did not enhance its effectiveness in treating this type of cancer.
