Spots Global Cancer Trial Database for Definitive Concurrent Hypofractionated Rth With Weekly Cisplatin in Locally Advanced SCCHN

Study Description

Brief Summary: The primary endpoint will be acute toxicity. Secondary endpoints included: late toxicity and quality of life; loco-regional control, disease free survival and overall survival.

Detailed Description: Head and neck cancer is considered the 6th most common cancer all over the world, with 890,000 new cases and 450,000 deaths in 2018 (1). The histologic type in more than 90% of head and neck cancer is squamous cell carcinoma (SCC) (2). The incidence of SCC in head and neck (SCCHN) continues to rise and is expected to increase by 30% in 2030, which means about 1.08 million new cases annually (3). Hospital-based studies in Egypt showed that SCCHN represents about 20% of all malignancies. The overall incidence of SCCHN in Egypt from 1999 to 2006 was approximately twice among males (476,000) than in females (273,000) (4). Males are affected significantly more than females, with a ratio ranging from 2:1 to 4:1 (5). Tobacco and alcohol consumption are the high-risk factors of SCCHN (6). Human papilloma virus (HPV), especially subtypes 16 and 18 are implicated risk factors in oropharyngeal cancer (7). Some studies found an association between HPV and P53 gene mutation, as HPV expresses two viral proteins (E6 and E7 proteins) that inactivates P53 and pRB genes, causing genomic instability and malignant transformation ((8)). SCCHN arises from the mucosal epithelium of the oral cavity, nasopharynx, oropharynx, hypopharynx, and larynx. HPV associated SCCHN arises primarily from the palatine and lingual tonsils of the oropharynx, whereas tobacco associated SCCHN arises primarily in the oral cavity, hypopharynx, and larynx. SCCHN is being increasingly treated by multimodality approaches combining surgery, radiotherapy (RT), and chemotherapy (CTH). Randomized controlled trials have demonstrated major improvements in loco-regional tumor control (LRC) from altered fractionation RT with CTH as compared with conventional fractionated RT (CFRT) (9). Altered fractionation schedules reduces tumor repopulation effect and seek to improve the therapeutic ratio between tumor cell killing and normal tissue damage. Additionally, some data showed that cancer patients are at higher risk of COVID-19 infection comparing with the general population due to many treatment visits, so hypo-RT schedules are better for these patients. hypo-RT utilizes a small number of fractions with a larger dose per fraction (\> 2Gy per fraction), shortening overall treatment time compared to a CFRT (9). Although a shorter treatment time can be obtained by applying a higher dose per fraction, it might also result in an increase in the incidence of late complications. The aim of this study was to investigate hypo fractionated intensity modulated RT (hypo-IMRT) with 62.5 Gy in 25 daily fractions over five weeks (2.5 Gy per fraction with weekly cisplatin 40mg/m2 in patients with high-risk stage II (T2N0, excluding glottic laryngeal) disease, stage III (T1-3 N1 or T3N0) and stage IV (T1-4N2 orN3). The primary endpoint will be assessment of acute toxicity. Secondary endpoints included: late toxicity and quality of life; LRC, disease free survival (DFS) and overall survival (OS).
