| Objective : To analyze and explore the characteristics of follow-up of recurrence of laryngeal cancer after surgery,so as to provide basis for early clinical diagnosis and treatment of patients with recurrence of laryngeal cancer after surgery.Results : Among 105 patients who were admitted to the hospital for re-examination with the diagnosis of "laryngocarcinoma after surgery",81 were diagnosed with recurrence of laryngocarcinoma through pathological biopsy,and the number of benign cases was 24;among 81 cases of tumor recurrence,CT diagnosis of recurrence of laryngeal cancer was positive.The number was 73 cases,specificity(0.625),sensitivity(0.901),positive predictive value(0.890),negative predictive value(0.652),and the diagnostic accuracy rate was(90.1%).Among 24 cases of benign lesions,CT diagnosis was correct 15 cases,the diagnosis accuracy rate was(62.5%),the CT and pathological consistency Kappa value was 0.534;the number of positive cases of recurrence of laryngeal cancer diagnosed by electronic laryngoscope was 47,specificity(0.875),sensitivity(0.580),negative predictive value(0.375),positive predictive value(0.940),diagnosis accuracy rate(58.0%),21 cases of electronic laryngoscope diagnosis in the benign lesion group,diagnosis accuracy rate(87.5%),and the coefficient of consistency Kappa value was 0.313.The accuracy(0.838),sensitivity(0.901),and negative predictive value(0.652)of CT in diagnosing postoperative recurrence of laryngeal cancer are all higher than the accuracy(0.648),sensitivity(0.580)and negative predictive value of electronic laryngoscope(0.375)and statistically significant(P<0.005).The first operation is the support laryngoscope laryngeal cancer surgery group and the first operation is the laryngeal dehiscence laryngeal cancer surgery group,the first surgery is the total laryngectomy group and the first surgery is the laryngeal partial laryngectomy group,and the first surgery is the staging of laryngeal cancer There was no statistically significant difference in the diagnosis rate of recurrent laryngeal cancer between the Laryngeal Cancer Surgery Group under the T1 Supporting Laryngoscope and the Laryngeal Cancer Surgery under the Supporting Laryngoscope Surgery Group with the First Surgery Laryngeal Cancer Stage of T2 Compared with the Recurrent Laryngeal Cancer(P>0.05).The probability of preserving laryngeal function in patients with recurrent laryngeal cancer found within six months after surgery is greater than that in six months to one year.There is a statistical difference in the probability of retaining laryngeal function in patients with recurrence found within one year(p<0.05);the recurrence treatment is the surgical treatment group with preserving laryngeal function and the recurrence treatment is the whole The median interval between diagnosis and recurrence in the laryngectomy treatment group was 6.00 months and 14.00 months respectively(p=0.00<0.05).Conclusion:1.Patients with laryngeal cancer in the first year after surgery,especially in the first half of the year,should be followed up more closely,and patients in the first half of the year after surgery should be followed up once a month,in order to detect recurrence earlier to save the patient’s life and preserve the patient’s laryngeal function as much as possible.2.Regardless of the first operation method,due to the change and destruction of the local anatomical structure from the operation,the recurrent laryngeal cancer and the initial laryngeal cancer show a completely different growth pattern.The growth of recurrent laryngeal cancer may be more inclined to infiltrate the laryngeal cavity.3.The detection rate and diagnostic efficiency of CT for tumor recurrence after surgical treatment of laryngeal cancer are better than those of electronic laryngoscopy.In clinical follow-up,more attention should be paid to CT examination or CT combined with electronic laryngoscopy,in order to detect the recurrence earlier and more accurately patient. |
