SPARE-1st: Surgery Alone vs Surgery Plus Postoperative Radiotherapy for Sinonasal Adenoid Cystic Carcinoma

Background: Sinonasal adenoid cystic carcinoma (ACC) is a rare type of cancer that starts in the nasal cavity or sinuses. Although surgery can remove the tumor, doctors often recommend radiation therapy after surgery to reduce the chance of the cancer coming back. However, radiation can cause long-term side effects such as bone damage, dry mouth, or difficulty opening the mouth. For patients whose tumor has been completely removed (called R0 resection) and who have early-stage disease (T1-T3) without spread to lymph nodes or other organs, it is not clear whether routine radiation therapy is always needed. Study Objective: This study aims to find out whether simply watching and waiting (surgery alone) is not worse than adding radiation therapy (surgery plus radiation) in terms of keeping patients free from cancer for at least 3 years. If surgery alone is shown to be as good as surgery plus radiation, some patients may be able to avoid the side effects of radiation. Study Design: This is a prospective, multicenter, real-world study. It is not a randomized trial - patients and their doctors will decide together whether to have radiation after surgery. We will follow about 200 patients from many hospitals across China. About half will receive surgery alone, and the other half will receive surgery followed by radiation therapy. All patients will be followed for at least 3 years. Hypothesis: We hypothesize that surgery alone is not inferior to surgery plus radiation therapy for 3-year disease-free survival, with a non-inferiority margin of a hazard ratio of 1.35. In other words, even if surgery alone has a slightly higher risk of cancer returning, the difference is small enough that avoiding radiation side effects may still be worthwhile. Main Outcome: The main outcome is the percentage of patients who are alive and free from cancer recurrence (local, regional, or distant) or death from any cause at 3 years after treatment. Potential Impact: If our hypothesis is confirmed, this study could change current practice. Many patients with completely resected, early-stage sinonasal ACC might safely avoid postoperative radiation and its long-term side effects, improving their quality of life without compromising cancer control.

Surgery Plus Postoperative Radiotherapy for T4 Sinonasal Adenoid Cystic Carcinoma

This observational study follows patients with T4 stage sinonasal adenoid cystic carcinoma (a rare cancer of the nasal cavity/sinuses) who receive standard treatment: surgery followed by postoperative radiotherapy. The main goal is to measure the 3-year progression-free survival rate (the percentage of patients alive without cancer growth or spread). We will also assess overall survival, recurrence, side effects, and quality of life. This multicenter, prospective study will provide much-needed real-world data to improve patient counseling and guide future research.

Pembrolizumab Combined With Cetuximab for Treatment of Recurrent/Metastatic Head & Neck Squamous Cell Carcinoma

This is a prospective, multi-center, open-label, non-randomized, multi-arm phase II trial to evaluate the efficacy of combination therapy with pembrolizumab and cetuximab for patients with recurrent/metastatic HNSCC. There will be four patient cohorts, including a PD-1/PD-L1 inhibitor-naïve, cetuximab-naïve arm (Cohort 1), a PD-1/PD-L1 inhibitor-refractory, cetuximab-naïve arm (Cohort 2), a PD-1/PD-L1 inhibitor-refractory, cetuximab-refractory arm (Cohort 3), and a cutaneous HNSCC arm (Cohort 4). A total of 83 patients (33 in Cohort 1, 25 in Cohort 2, 15 in Cohort 3, and 10 in Cohort 4) will be eligible to enroll. Patients will be enrolled at 4 sites: UC San Diego Moores Cancer Center, UC Los Angeles Jonsson Comprehensive Cancer Center, University of Michigan Comprehensive Cancer Center, and University of Washington Siteman Cancer Center.

A Study of Becotatug Vedotin (MRG003) Combined With Epirubicin as Neoadjuvant Therapy for EGFR-Positive, Unresectable Recurrent Sinonasal Adenoid Cystic Carcinoma

This prospective, multicenter clinical study aims to evaluate the efficacy and safety of neoadjuvant therapy with MRG003 (Becotatug vedotin) combined with epirubicin in patients with EGFR-positive, unresectable recurrent sinonasal adenoid cystic carcinoma (SNACC). The primary question is whether this combination can achieve a sufficient objective response rate (ORR) to enable subsequent radical surgery or improve disease control.

Tazemetostat Expanded Access Program for Adults With Solid Tumors

Patients with a diagnosis listed under "conditions" below are eligible to be considered for the EAP. These conditions must be serious or life-threatening at the time of enrollment and appropriate, comparable, or satisfactory alternative treatments must have been tried without clinical success. Patients with conditions not listed under "conditions" below are not eligible for the tazemetostat EAP.

Epirubicin Interventional Chemotherapy for Sinonasal Adenoid Cystic Carcinoma (SNACC): A Prospective Study

This study is for patients with locally advanced sinonasal adenoid cystic carcinoma (SNACC), a rare and challenging cancer that tends to invade nerves and the skull base. The research aims to test a new precise treatment strategy. First, all participants will receive three sessions of "interventional chemotherapy" (transarterial chemoembolization) with the drug Epirubicin, which delivers high-dose chemotherapy directly to the tumor to shrink it as much as possible. About 4-6 weeks after the third session, doctors will use MRI scans to evaluate how well the tumor responded. Based on this response, patients will follow one of two personalized treatment paths: those whose tumors did not completely disappear will undergo surgery followed by radiotherapy; those whose tumors show complete disappearance on imaging will receive precise radiotherapy alone, potentially avoiding major surgery. This is a prospective, multicenter study. The main goals are to evaluate the safety and effectiveness of this response-adapted strategy and to see if it can improve outcomes for patients with this difficult-to-treat cancer.

Prospective Sinonasal Cancer Multi-institution Study

This is a multi-institution prospective study of patients with sinonasal malignancies. The goal of this study is to learn more about the course of sinonasal cancer, treatment outcomes, and patient quality of life. In addition, central mutational and genomic analysis of tumor tissue will be evaluated.

Induction Chemotherapy and Tazemetostat for Locally Advanced SMARCB1-deficient Sinonasal Carcinoma

SMARCB1-deficient sinonasal carcinoma is very locally advanced malignancy at diagnosis which often precluded upfront radical resection. The investigators are now proposing a phase II single-arm study on tazemetostat in combination with docetaxel, cisplatin and 5-FU (known as TPF regimen) as preoperative therapy for locally advanced non-metastatic SMARCB1 (INI-1)-deficient sinonasal carcinoma, followed by radical resection and/or post-operative radiation therapy (with or without concurrent chemotherapy), and tazemetostat for another 6 months. It is hypothesized that addition of tazemetostat will improve objective response rate, resectability rate, orbit preservation rate after surgery, and hopefully survival outcomes with manageable safety profiles.
