CO2激光手术治疗声门型喉癌疗效分析

OBJECTIVE: To evaluate the curative effect of CO2 laser in treatment of glottic carcinoma. METHODS: Retrospective analysis of 217 cases of early glottic laryngeal carcinoma treated with laser surgery were carried out. Among these cases, Tis were 22 cases, T1a 108 cases, T1b 38 cases, T2 46 cases, T3 3 cases. 1 case being applied vocal cord excision due to failure of tumor exposure. The follow-up period was 3 to 9 years. RESULTS: Relapse were detected in 21 out of 217 cases of glottic laryngeal carcinoma after CO2 laser surgery under self-retaining laryngoscope. The recurrent rate was 9.7% (21/217). Recurrent ratio of T1a, T1b, T2, T3 were 5.6% (6/108), 21% (8/38), 13.0% (6/46), 1/3 respectively, with significant differences among groups (chi 2 = 6.102, P < 0.01). The recurrent rate was 21.6% of tumors offended the anterior commissure, versus 5.1%(8/157) with no involvement of anterior commissure (chi 2 = 13.64, P < 0.01). 217 cases received laser surgery as the only treatment, 201 cases were still alive. 4 failed to be followed-up(taken into dead number), 12 cases were dead. 3 year survival rate was 97.2%(211/217), 5 year survival rate was 89.4%(118/132). CONCLUSION: It was reliable to use laser surgery in treatment of early glottic laryngeal cancer. The advantages of it included lower complication rate and vocal function was well retained.

Management of T3N0M0 Glottic Carcinoma: Therapeutic Outcomes

Background The best therapeutic approach for the treatment of T₃N₀M₀ (stage III) glottic carcinoma is controversial. Method A retrospective study of Tumor Research Project data were performed using patients with T₃N_OM_O glottic squamous cell carcinoma treated with curative intent by seven different treatment modalities from January 1950 to December 1996 at Washington University School of Medicine/Barnes‐Jewish Hospital. Results Two hundred patients with T₃N_OM_O glottic carcinoma were treated using seven modalities: total laryngectomy (TL, n = 30), TL with neck dissection (TL/ND, n = 40), conservation surgery alone (CS, n = 22), radiation therapy alone (RT, n = 29), TL combined with RT (TL/RT, n = 31), TL and ND combined with RT (TL/ND/RT, n = 36), and CS combined with RT (CS/RT, n = 12). The overall 5‐year observed survival rate (OS) was 54% and the 5‐year disease‐specific survival rate (DSS) was 67%. The 5‐year DSS for the individual treatment modalities included TL, 65.4%; TL/ND, 76.5%; CS, 71.4%; RT, 56.5%, TL/RT, 51.9%; TL/ND/RT, 71.4%; and CS/RT, 80%. There was no significant difference in DSS for any individual treatment modality (P = .375). The overall local and regional control rate was 74% (148 of 200). The overall recurrence rate was 37.5% with recurrence at the primary site and in the neck of 19.5% and 11%, respectively. Recurrence was not related to treatment modality. The 5‐year DSS after treatment of recurrent cancer (salvage rate) was 35.8%. The incidence of distant metastasis was 11% and for second primary cancers it was 19.5%. There was no statistically significant difference in survival between necks initially treated (72%, 5‐y DSS) versus necks observed and later treated if necessary (70%, 5‐y DSS) (P = .797). Conclusions The seven treatment modalities had statistically similar recurrence, complication, and survival rates. Patients with clear surgical margins have a significant survival advantage compared with patients with close and involved margins. Because postoperative radiation therapy in patients with positive margins did not improve survival, formal re‐resection of the site of the positive margin should be considered. In patients whose N0 neck was not treated electively, close follow‐up observation with meticulous examinations combined with appropriate treatment for subsequent neck disease resulted in a similar survival rate compared with those patients whose N0 necks were treated initially. Six‐year minimum follow‐up is recommended for early identification of primary and neck recurrence and for discovering expected second primary cancers. Patients treated with RT and CS had statistically similar rates of survival, maintenance of voice, and acquired permanent tracheal stoma. CS is a valid alternative to RT in treating highly selected patients with T₃N_O glottic carcinoma.     

Voice quality after endoscopic laser surgery and radiotherapy for early glottic cancer: objective measurements emphasizing the Voice Handicap Index

We analyzed the functional outcome and self-evaluation of the voice of patients with T1 glottic carcinoma treated with endoscopic laser surgery and radiotherapy. We performed an objective voice evaluation, as well as a physical, emotional and functional well being assessment of 19 patients treated with laser surgery and 18 patients treated with radiotherapy. Voice quality is affected both by surgery and radiotherapy. Voice parameters only show differences in the maximum phonation time between both treatments. Results in the Voice Handicap Index show that radiotherapy has less effect on patient voice quality perception. There is a reduced impact on the patient’s perception of voice quality after radiotherapy, despite there being no significant differences in vocal quality between radiotherapy and laser cordectomy.     

Voice quality after laser surgery or radiotherapy for T1a glottic carcinoma

OBJECTIVE: To compare the effect on phonation of radiotherapy and endoscopic laser surgery for stage T1a glottic squamous cell carcinoma. STUDY DESIGN: Retrospective. METHODS: Patients treated for stage T1a glottic carcinoma from August 1994 to March 2000 and who had been followed for at least 1 year were candidates. Eight patients who underwent radiotherapy and 22 who underwent laser surgery were enrolled. Indirect laryngoscopy and stroboscopic examination were performed, and voice quality was analyzed using standard parameters. RESULTS: Maximum phonation time, average airflow rate, sound pressure level, and average fundamental frequency during unconditional phonation were similar after laser surgery and radiotherapy. However, compared with normal men who were 50 years of age or older, the average fundamental frequency was higher after laser surgery. CONCLUSIONS: Contrary to some reports, the voice quality is minimally affected by laser surgery for T1a glottic carcinoma, and outcome is similar to radiotherapy. The average fundamental frequency is higher than normal after laser surgery, but the effect on the quality of life was trivial.     

Long‐Term Results of Radiotherapy for T1a and T1bN0M0 Glottic Carcinoma

Objective/Hypothesis: The purpose of this study is to determine the prognostic factors for local control and significance of total radiation dose in T1 glottic cancer. Study Design: Retrospective study. Methods: Data from 163 patients with T1 N0 M0 Stage I glottic squamous cell carcinoma (T1a: 115, T1b: 48) who were treated with radiotherapy alone during 1976 to 2002 were analyzed retrospectively. Age, source, total dose, field size, overall treatment time, and average fraction size were set as variables in multivariate analysis. Results: The 5‐year local control rates (LCR) were 92.3% and 85.0% for patients with T1a and T1b glottic carcinoma, respectively. Only total radiation dose (P = .048) was a significant prognostic factor for local control in multivariate analysis of T1b glottic carcinoma. Local control in the higher total dose group was better than that in the lower total dose group (5 year LCRs were 100% and 76% for the group of >66 Gy and the group of ≤66 Gy, respectively. P = .024, logrank test). None of the treatment parameters were shown to be significant prognostic factors in multivariate analysis of T1a glottic carcinoma. Conclusions: Radiotherapy with a total dose of 67 to 70 Gy seemed to be required for local control in T1b glottic carcinoma. No significant benefit of total radiation dose >64 Gy was shown in the analysis of T1a glottic carcinoma.     

How often is total laryngectomy necessary for the treatment of T1 failures after radiotherapy or cordectomy?

Between 1992 and 1998, 547 patients (pts) with laryngeal SCC were diagnosed and treated in our department, 145 (27%) of whom presented with glottic tumors T₁N₀M₀ (125 T_1a and 20 T_1b). Seventy-eight (54%) were treated surgically with cordectomy and 67 (46%) with radiotherapy. After a median follow-up time of 43 months, 22 (15.2%) of the 145 pts presented with recurrent disease. In more detail, 16 (13%) of the 125 T_1a pts and 6 (30%) of the 20 T_1b pts had recurrences. Among the 78 surgically treated patients only 4 (5%) had recurrence, while 18 (27%) of the radiotherapy group relapsed. The difference is statistically significant (log rank test, P = 0.0001 < 0.05). After salvage treatment, of the 67 pts of the radiotherapy group 57 (85%) remain disease-free, 49 (73%) retaining their larynx intact and 1 only having undergone cordectomy. Among the cordectomy group 75 (96%) pts remain disease-free with only 1 having had a total laryngectomy. Using the Kaplan-Meier method and calculating the disease-free survival regardless of salvage treatment, there is no doubt that surgical treatment statistically is more successful than radiotherapy (log rank test, P = 0.01 < 0.05). Analysis of parameters such as tumor differentiation and T_1a or T_1b staging, which indeed influence the overall recurrence rate, did not alter the favorable outcome after surgical treatment.
