Value of postoperative radiation therapy for regional control after dissection in head and neck squamous cell carcinoma cases.

OBJECTIVE: We aimed to define clinicopathologic risk factors associated with regional recurrence (RR) and thus the effectiveness of postoperative radiotherapy (PORT) for neck control for head and neck squamous cell carcinomas (HNSCCs) with differing cervical lymph node status. METHODS: A retrospective study was performed in 196 HNSCC patients with pathologically positive neck node (N+) to evaluate the high-risk factors for RR and to define the role of PORT in control after neck dissection and postoperative radiotherapy (PORT). RESULTS: Overall, the RR rate after neck dissection and PORT was 29%. Extracapsular spread (ECS) was confirmed to be the only independent risk factor for RR. There were no significant risk factors associated with RR in the ECS- group. The 5-year disease-specific survival rate was 45%, which descended to 10% with the emergence of RR. CONCLUSIONS: ECS remains a determined risk factor for RR after neck dissection and PORT in patients with N+. PORT alone is not adequate for preventing RR in the neck with ECS after neck dissection. More intensive postoperative adjuvant therapies, especially combined chemotherapy and radiotherapy, are needed to prevent regional failure in HNSCC patients with ECS.

[Preliminary report of laryngeal preservation in the surgical salvage of recurrent laryngeal cancer].

OBJECTIVE: To explore the plausibility of laryngeal preservation in salvage surgery of recurrent laryngeal carcinoma. METHODS: Comprehensive clinical and radiological assessments on a specific group of patients with recurrent laryngeal cancer and their relapsed tumors were carried out to determine the methods and indications of salvage surgery for preservation of laryngeal functions. Salvage surgery with preservation of larynx was performed in a selective of 36 laryngeal cancer patients with relapsed tumors in their larynges after radiotherapy or partial laryngectomies. All patients were regularly followed up after discharge from the hospital. Postoperative survival was calculated by Kaplan-Meier's method. RESULTS: Among various laryngeal preservation regimens given, a second transoral laser surgery was carried out in 4 cases, horizontal hemilaryngectomy in 4 cases, vertical hemilaryngectomy in 13 cases and Majer-Piquet's operation in 15 cases, respectively. Simultaneous neck dissection was conducted in 18 cases. Postoperative complications were encountered in 6 cases, most common of which were local infection and laryngeal fistula with no hospital mortality and other major morbidities. Five cases with immediate postoperative complications were cured with proper management. The remained one case undergone vertical partial laryngectomy for recurrence after tumor resection via laryngeal fissure received postoperative radiation due to positive surgical margin, and complicated laryngeal atresia and obstruction with loss of his laryngeal functions. Local recurrence was observed in 5 cases and simultaneous locoregional recurrence was seen in 1 case, with the resulting local control rate of 83.3% (30/36). The 3-year postoperative survival rate was 80.6%. The cause of death was tumor recurrence in 3 cases, distant metastasis in 3 cases and non-tumor-associated disease (heart attack) in 1 case, respectively. CONCLUSIONS: Salvage surgery with laryngeal preservation can be carried out in the selected cases with early or locally-confined recurrent lesions within the larynx, on the condition that the recurrent tumors be assessed thoroughly and indications for associated surgical techniques be evaluated properly.

[Outcomes of salvage laryngectomy after initial radiation failure in laryngeal squamous cell carcinoma].

OBJECTIVE: To investigate survival outcomes of salvage surgery preformed for laryngeal squamous cell carcinoma that recurred or progressed after radiotherapy alone. METHODS: A review of 72 patients who underwent salvage laryngectomy for laryngeal cancer failed in initial radiation therapy between 1996 and 2005 was performed. The tumor persistence occurred in 50 cases and recurrence in 22 cases. All patients received salvage total laryngectomy and radical neck dissection. Survival analysis was performed by using Kaplan-Meier method, Log-rank test and Cox proportional hazard model. RESULTS: Thirty patients developed a postoperative complication after salvage surgery. Pharyngocutaneous fistula occurred in 15(20.8%) patients. During 5 years after salvage surgery, the rates of tumor recurrence, distant metastasis and second malignancy were 34.7%, 22.2% and 6.9%, respectively. Kaplan-Meier analysis showed that overall 3 year and 5 year survival rates of those patients after operation were 45.8% and 36.1%, respectively. Univariate analysis indicated that N restage, tumor persistence/recurrences after radiotherapy, surgical margin status, level of tumor invasion, pathologic N stage, extracapsular nodal spread and invasion of nonlymphotic structures were significantly associated with overall survival. Multivariate analysis showed the most significant prognostic factors were tumor persistence or recurrence after radiotherapy, surgical margin status and level of tumor invasion. CONCLUSIONS: Surgical salvage remains the gold standard for management after failure of initial radiation therapy. The extent of tumor invasion must be assessed sufficiently before operation, and the surgical margin status must be identified in operation by using a frozen sectioning approach, especially in patients with tumor invasion to muscle/cartilage and tumor persistence after radiotherapy.

[Investigations on salvage surgery-related problems for stomal recurrence after total laryngectomy].

OBJECTIVE: To explore the related issues concerning salvage surgery for stomal recurrence (SR) after total laryngectomy. METHODS: A retrospective study was conducted to analyse the clinical data from 36 patients suffering from SR after total laryngectomy, who were treated by salvage surgery from January 1990 to January 2006. Some related issues concerning salvage surgery for SR were studied and analysed, which include preoperative evaluations, surgical approaches and techniques, management of perioperative complications and outcomes of treatment. RESULTS: After careful preoperative evaluations and predictions, a complete resection of tumor was achieved in 33 out of 36 SR patients. Two patients sacrificed because of ruptures of major vessels including the common carotid eaters and the innominate artery 3 weeks and 2 months after the operation. The overall 1-year, 2-year and 3-year survival of this group of patients were 68.8%, 42.8% and 12.5%, respectively. Besides, postoperative complications comprise 23 cases of hypothyroidisms, 6 cases of wound infection and saliva leakage, 8 cases of donor site complications (including dehiscence of wound in 3 cases, chest wall hematomas in 4 cases, and tumor seeding in 1 case), and hypopharyngeal stenosis in 4 cases, all of which were properly and promptly managed with uneventful outcomes. CONCLUSIONS: SR after total laryngectomy is a dangerous and complicated status with poor prognosis. For the purpose of saving or elongating the patients's lives, the salvage surgery needs to be done on the condition that indicated candidates are properly selected, preoperative evaluations carefully conducted, and perioperative abnormal conditions unerroneously delt with.

[Multi-modalities for reconstruction of circumferential defects in the pharyngoesophageal region].

OBJECTIVE: To investigate the feasibility of multi-modalities in the reconstruction of circumferential defects after resection of cancers in pharyngoesophageal regions, and to compare the pros and cons between different surgical procedures. METHODS: According to the nature and extend of defects, five different methods including pectoralis major myocutaneous flap, laryngeal tube replacement, free jejunum, free forearm flap and gastric pull-up were used to reconstruct the circumferential pharyngoesophageal defects in 72 patients. Function of deglutition and restoration of swallowing was regularly followed up and objectively evaluated. RESULTS: A total of 35 cases of pectoralis major myocutaneous (PM) flaps, 8 cases of laryngeal tube replacement, 12 cases of free jejunum, 12 cases of free forearm flaps and 16 cases of gastric pull-up were performed. Different complications including wound infection, pharyngeal fistula, partial necrosis of PM flap, partial necrosis of gastric wall, stricture of anastomotic site were encountered in 15 cases. All patients survived the operation except one due to partial necrosis of the gastric wall. Two of 4 patients who developed anastomotic stricture can ingest half-liquid food, the remaining cases regained normal deglutition function. The mean postoperative follow-up time was 1. 6 years with 2-year survival rate of 45.3%. CONCLUSIONS: Circumferential defects resulting from resection of carcinomas in pharyngoesophageal region can be reconstructed with different operative techniques depending on the nature and extend of the defects. Once the operative indications are properly selected, the good reconstructive results are to be achieved.

[Long-term results of one stage tracheoesophageal end-side anastomosis voice restoration after total laryngectomy].

OBJECTIVE: The purpose of this study is to discuss long-term results of one different kind of voice restoration after total laryngectomy with 10 years experience. METHOD: One stage tracheoesophageal end-side anastomosis after total laryngectomy was performed in 36 patients from 1991-1996. The key technique of this operation is to make a tongue-ship flap(1.5 cm x 1.5 cm-1.8 cm x 1.5 cm) with tracheal membranous part and dissect it from the esophagus to 1 cm below the upper incisal margin of trachea. Then a 0.8 cm middle vertical incision was made on the lowest anterior wall of the separated esophagus. Folding the tongue-ship flap posteriorly to approximate the esophagus incision and make an end-side anastomosis. Close the upper incisal margin of trachea with left to right direction suture. The follow up time is 5 - 10 year. One lost follow 2.5 years later and was judged as dead. RESULT: The short-term and long-term success rate were 69% (25/36) and 83% (30/36) respectively. The 3-, 5- and 10 year survival rate are 72%, 69%, 69%, respectively. CONCLUSION: This technique does not change the pattern of total laryngectomy and various neck dissections do not affect voice rehabilitation. Advantages of the operation: easy to operate and learn; the special form of tracheoesophageal shunt (high in the tracheal side and low in esophageal side) prevents the aspiration; high successful rate, excellent speech, fluent language, good acceptability and lower aspiration.
