Abstract:
Objective: To analyze the effectiveness, safety and factors influencing the clinical prognosis of patients with hypopharyngeal carcinoma in T4b by nonsurgical treatments. Methods: The clinical data of 77 patients with T4b hypopharyngeal cancer treated in the College of Otolaryngology Head and Neck Surgery of the Chinese People's Liberation Army General Hospital from January 2010 to June 2021 were analyzed retrospectively. All were males, aged(57.0±8.0)years old. Patients were treated with induction chemotherapy plus concurrent chemoradiotherapy. Kaplan Meier survival analysis was used to compare the effects of different factors on prognosis. Adverse reactions during treatments and the causes of death were analyzed. Results: 98.7% of 77 patients with T4b hypopharyngeal cancer completed the chemotherapy plan and 94.8% completed the radiotherapy plan. The most common adverse reactions were grade 2 radiation oral mucositis (50/77, 64.9%) and grade 2 leukopenia (50/77, 64.9%). The incidence of grade 3 severe hoarseness was 7.8% (6/77), one patient (1.3%) underwent gastrostomy due to dysphagia, and pronunciation and swallowing function were effectively preserved in other patients. The overall survival rate was 71.9% at 1 year, 45.6% at 3 years and 29.7% at 5 years. The location of tumor, the presence of liquefaction necrosis in tumor, the use of molecular targeted drugs and the approach of radiotherapy were independent factors,each of which that affected the prognosis of T4b patients with advanced hypopharyngeal cancer [HR (95%CI) were 1.867(1.085-3.213), 3.018 (1.437-6.335), 0.372 (0.181-0.764) and 2.158 (1.015-4.588), respectively, P<0.05]. The two leading causes of death with high incidence were disease recurrence (12/32, 37.5%) and cervical large vessel rupture and hemorrhage (11/32, 34.4%). Conclusions: Non-surgical comprehensive treatment offers a high laryngeal preservation rate in patients with T4b hypopharyngeal cancer. The location of tumor, the liquefaction necrosis within tumor, the use of molecular targeted drugs, and the approach of radiotherapy are independent prognostic factors.
