Treatment of neuroendocrine neoplasms of the larynx.

The best treatment for carcinoid tumor is surgical excision. The mainstay of treatment for atypical carcinoid tumor is wide surgical resection, often with elective neck dissection. Although it is not effective in the management of paragangliomas and carcinoid tumors, primary radiation therapy with adjuvant chemotherapy is the treatment of choice for small cell neuroendocrine carcinoma of the larynx. Management of laryngeal paraganglioma is surgical and may often be accomplished by partial laryngectomy. Most tumors are supraglottic and may be resected via modified lateral pharyngotomy. Preoperative angiography and embolization are occasionally useful.     

Results of treatment of 584 laryngeal cancers at the Ear-Nose-Throat Clinic of Marburg University

The results in the management of 460 vocal cord carcinomas and 124 supraglottic carcinomas are reported. Of the vocal cord carcinomas, 63.3% were diagnosed in the early Tis and T1 stage. Seventy-six tumors were resected endoscopically, 128 by laryngofissure and chordectomy. Not one of these patients has lost his life, larynx or voice. In bilateral tumors of the T1b category, 2 patients developed local recurrences and lost their larynx. Sixty-two carcinomas of the Tis, T1a and T1b categories were irradiated primarily. Two of these patients died and 14 underwent laryngectomy for local recurrence. In T2 carcinomas a 5-year cure rate of 87.5% was achieved by vertical partial resection. The 5-year cure rate after laryngectomy or laryngectomy with neck dissection for T2N0 and T2N+ carcinoma was 86.2% and 75.0% respectively. Most treatment failures were due to late metastases which could not be controlled. In T3 carcinomas with a 5-year cure rate of 71.4% (N0) and 70.0% (N+) respectively, treatment failures were also mainly seen in patients with N0 necks where we did not carry out a prophylactic neck dissection. Five-year survival rates for primary surgery in supraglottic T1-T4 carcinomas were 100%, 82.4%, 84% and 58.3%. The widely hel opinion that laryngeal carcinoma should only be subjected to surgery for irradiation failure can no longer be sustained. More patients lose their larynx or their life after irradiation of small carcinomas than after primary surgery. Furthermore, too many patients have to undergo two major cancer treatments (irradiation and salvage surgery). In larger carcinomas radiotherapy produces a lower survival rate and too many patients require two stressful cancer therapies. The number of retained larynges is not substantially higher than with primary surgery. Primary irradiation for selected cases should be part of every therapy concept that aims at an adequate and individual treatment of every patient.     

Salvage surgery after failure of nonsurgical therapy for carcinoma of the larynx and hypopharynx

BACKGROUND: For larynx preservation, radiotherapy is gaining popularity for primary treatment of laryngeal and hypopharyngeal cancer, reserving surgery for salvage. OBJECTIVE: To analyze the outcome of salvage surgery after failure of primary radiotherapy. DESIGN: Nine-year retrospective outcome analysis. SETTING: University referral center. PATIENTS: Fifty-four patients with squamous cell carcinoma of the larynx (n = 39) or hypopharynx (n = 15). RESULTS: For laryngeal cancer, mean interval from radiation to detection of recurrence was 14.5 months (range, 2-66 months). Twenty-three patients (59%) presented with a more advanced tumor stage after radiation than at the initial evaluation. Total laryngectomy was needed in 36 patients (92%). Disease-specific 5-year survival rate was 63%. Survival of patients with small recurrent tumors was statistically significantly better than those with advanced tumors (P =.004). For hypopharyngeal cancer, mean interval from radiation to detection of the recurrence was 10.6 months (range, 3-40 months). Total laryngopharyngectomy was needed in 8 of 9 patients with local recurrrence; neck dissection, in 6 patients with regional recurrence. Disease-specific 5-year survival rate was only 20%. Recurrent tumor and node stages did not influence the outcome. Patients with regional recurrences did no better than those with local ones. CONCLUSIONS: Salvage surgery in laryngeal cancer achieves good results, especially for small recurrences. Because of tumor progression, larynx preservation is seldom possible at the time of salvage. Salvage surgery in hypopharyngeal cancer shows poor survival regardless of tumor stage and despite radical surgical procedures, and can be recommended only for carefully selected patients.

The submandibular triangle in squamous cell carcinoma of the larynx and hypopharynx

A 15-year retrospective analysis was carried out at the University of Illinois College of Medicine, Chicago, reviewing the tumor staging and pathology data of 239 patients treated for carcinoma of the larynx and hypopharynx requiring laryngectomy alone, laryngectomy with neck dissection, or laryngopharyngectomy and neck dissection. Surgery was the primary treatment modality in 205 of the 239 cases, with the remaining 34 having surgery to treat radiation therapy failure. Primary tumors were located within the supraglottic region, the glottic region and, less commonly, the pyriform sinus. Ninety-five of the 239 patients either presented with or developed nodal metastases following initial treatment. Of these, only two had tumors within the lymph nodes of the submandibular triangle. This data corroborates impressions that tumors of the larynx and hypopharynx rarely metastasize to the submandibular triangle and that sparing this area during neck dissection for lesions of the larynx would seem justified.     

Elective neck dissection during salvage laryngectomy

PURPOSE: To evaluate the rate of occult metastases detected with elective neck dissection during salvage laryngectomy for radiation failures. METHODS AND MATERIALS: Retrospective review of 63 patients failing radiation therapy treated with salvage surgery between 1970 and 1999. Charts were reviewed for tumor stage, neck treatment, complications, surgical time, and survival. Median follow-up for patients with glottic and supraglottic cancers was 7.8 and 4.5 years, respectively. RESULTS: Thirty-one of 41 glottic cancer patients received elective neck dissections. Three (10%) of 31 had occult metastases. Recurrent staged rT3 and greater tumors showed a 20% rate of occult metastases. No survival advantage was noted between patients treated with elective neck dissection and those followed expectantly (P = .87). Cartilage invasion and perineural invasion in the larynx were associated with a higher risk of occult metastases (P < .05). Ten of 22 supraglottic cancer patients received elective neck dissections. Two (20%) of 10 had occult metastases, and a statistically significant survival advantage was not noted (P = .49). CONCLUSIONS: We recommend bilateral neck dissection at the time of laryngectomy for recurrent staged rT3/4 tumors and all patients with recurrent supraglottic cancers because of the higher rate of occult metastases.

Transoral CO<Subscript>2</Subscript> laser management for selected supraglottic tumors and neck dissection

This study aimed to evaluate transoral laser resection as a method of choice for conservation surgery for supraglottic laryngeal carcinoma in carefully selected patients. Between 1987 and 2006, 55 patients with early supraglottic carcinoma were selected for transoral laser surgery. The outcome of the endoscopic CO₂ laser resection and larynx-sparing functional results without tracheotomy was evaluated. Fifty-five patients with T1, T2 supraglottic carcinomas underwent transoral CO₂ laser resection and seven patients with manifest neck metastasis required a neck dissection at one session with additional postoperative radiation therapy. There was no need for tracheotomy; deglutition was moderately disturbed. Forty of the 55 (73%) patients had no signs of recurrence to date. Fifteen patients with local recurrences underwent salvage therapies: six repeated laser excisions, three radiotherapies, four supraglottic laryngectomies and two total laryngectomies. Laser-specific survival is 84% and larynx preservation is 96%. The overall 5-year-survival after salvage treatment is 98%. Development of late metastasis required five radical neck dissections (RND) and radiation therapy. The results indicated that transoral laser resection can control early supraglottic cancer in selected patients and can be combined with simultaneous neck dissection with less morbidity than “open surgery”.     

Is routine bilateral neck dissection absolutely necessary in the management of N0 neck in patients with supraglottic carcinoma?

The supraglottic larynx has a rich lymphatic network that places patients with supraglottic laryngeal carcinomas at high risk for early dissemination of the disease into the cervical lymphatics. Therefore, elective neck treatment of clinically N0 neck in patients with supraglottic carcinomas is widely accepted as a standard approach. However, the issue whether elective neck treatment should routinely be directed on both sides of the neck is still controversial. The present study is aimed at determining whether T2–T4 stage supraglottic carcinomas require bilateral neck dissection in the management of N0 necks. We designed a prospective study on 72 patients with N0 supraglottic laryngeal carcinoma. Patients were divided into three groups according to the site and extension of the primary tumors. Group I consisted of 21 patients with lateralized (clear lateral) lesion reaching but not crossing the midline. Group II comprised 25 patients with cancer largely involving one side and crossing to the midline. Group III included 26 patients with carcinoma equally involving both sides of the larynx or growth into the midline larynx. All patients underwent bilateral lateral neck dissection in conjunction with various types of laryngectomies selected to the status of the primary. Of the 72 patients, 16 were found to have occult regional metastases in pathologic examination (9 pN1, 4 pN2b, 3 pN2c). The prevalence of occult metastases proportionally increased with T stage from 8.3 to 22.7 and 31.2%, respectively, for T2, T3 and T4. Bilateral neck metastases were found in 2 of 26 patients (7.7%) with central lesions. There was only one patient (4%) with both ipsilateral and contralateral lymph node metastasis in group II. None of the 21 patients with lateral lesion (group I) had contralateral neck metastasis. Routine bilateral elective neck dissection may not be a part of the surgical procedure in all supraglottic laryngeal carcinoma patients. Bilateral neck dissection should be preferred for cases with central tumors and lateral tumors with positive nodes in the ipsilateral side of the neck.     

Analysis of multicentricity in supraglottic laryngeal carcinoma treated with partial laryngeal surgery

A clinicopathological analysis of multicentricity in patients treated with either supraglottic horizontal laryngectomy or supracricoid partial laryngectomy for supraglottic squamous cell carcinoma of the larynx was conducted. This study included 63 patients who underwent supracricoid partial laryngectomy or supraglottic horizontal laryngectomy for T2 or T3 supraglottic laryngeal squamous cell carcinoma. The patients were divided into two groups: Group 1 included patients with one focus of the tumor (monocentric), and Group 2 included patients who had more than one focus of the tumor (multicentric) diagnosed after pathology examination. Forty-eight (76.2 %) of the patients had one focus of the tumor (Group 1) and 15 (23.8 %) of the patients had more than one focus of the tumor (Group 2). The rates of lymph node metastasis in Group 1 and Group 2 were 12.5 and 60 %, respectively. The second focus was invasive in seven (46.6 %) of the patients, carcinoma in situ in six (40 %) of the patients, and both invasive and carcinoma in situ in two (13.3 %) patients. The overall 3- and 5-year survival rates of Groups 1 and 2 were 77.1–66.7 % and 56.2–46.7 %, respectively. With regard to survival rates, no statistically significant difference was observed between Group 1 and Group 2 (p = 0.576). The lack of statistical significance might have been associated with the low sample size. Although multicentric tumors of the supraglottic larynx have high incidence of nodal metastasis, no significant increase in the rate of recurrence was determined.     

Laryngeal long-term morbidity after supraglottic laryngectomy and postoperative radiation therapy

PURPOSE: This study was performed to investigate factors associated with laryngeal morbidity when postoperative radiation therapy (RT) is added to supraglottic laryngectomy. MATERIALS AND METHODS: From 1980 to 1994, 56 patients affected with T1 to 4 N0 to 2c supraglottic squamous cell carcinoma selected for standard (59%) or extended (41%) supraglottic laryngectomy at 2 different institutions were retrospectively analyzed. Most of the patients (91%) also underwent neck dissection. Approximately 80% of the patients had stage T4 primary lesions or N2 neck disease. Postoperative RT was added for presumed microscopic disease at the primary site (13 patients), regional nodes (23 patients), or both (20 patients). Median delivered doses to the larynx and to the neck were 50 Gy (range, 40 to 64 Gy) and 46 Gy (range, 40 to 64 Gy), respectively. Median follow-up for living patients is 11 years (range, 2.8 to 16.9 years). Laryngeal complication was defined as the appearance of grade 2 or higher toxicity according to the European Organization for Research and Treatment of Cancer (EORTC) and the Radiation Therapy Oncology Group (RTOG) scoring systems. RESULTS: Two- and 5-year actuarial locoregional control rates were 85+/-5% and 83+/-5%, respectively. Thirty patients (54%) developed laryngeal complications. However, just one patient experienced grade 4 laryngeal oedema requiring permanent tracheostomy. Estimated actuarial survival without laryngeal complications were 50+/-7%, 43+/-7%, and 39+/-7% at 2, 5, and 10 years, respectively. At univariate analysis, treated volumes (P = .03) and total dose to the larynx (P = .03) were significantly associated with local toxicity. A trend was observed also for the maximum dose to the neck (P = .06) and dose per fraction (P = .09). A multivariate Cox proportional hazards model showed total dose to the larynx to be the only independent predictor of toxicity (P = .03). The hazard ratio of laryngeal toxicity was 2.2 (95% confidence interval: 1.1/4.6), for a total dose to the larynx greater than 50 Gy. CONCLUSION: After supraglottic laryngectomy, postoperative RT to the neck does not affect local morbidity, but careful RT treatment planning is necessary to avoid delivering a total dose to the larynx greater than 50 Gy.

Transoral carbon dioxide laser supraglottic laryngectomy and irradiation in stage I, II, and III squamous cell carcinoma of the supraglottic larynx: report of Southwest Oncology Group Phase 2 Trial S9709

OBJECTIVE: To evaluate feasibility, functional outcome, and disease control of endoscopic surgery and irradiation in patients with squamous cell carcinoma of the supraglottic larynx. DESIGN: Prospective, single-arm, phase 2 multi-institutional trial. SETTING: Southwest Oncology Group trial S9709. PATIENTS: Thirty-four patients diagnosed as having stage I, stage II, or selected stage III (T1-2N1M0) supraglottic laryngeal carcinoma enrolled from September 15, 1997, to December 1, 2001. INTERVENTIONS: Transoral supraglottic laryngectomy by carbon dioxide laser followed by planned postoperative radiotherapy. MAIN OUTCOME MEASURES: Three-year progression-free survival, proportion of patients requiring tracheostomy as a result of surgery, and time to adequate oral intake. RESULTS: All 34 patients underwent surgery without major protocol deviation. Thirty-two patients (94%) completed planned postoperative radiotherapy without major deviation. At the time of analysis, only 1 patient (3%) had documented local disease recurrence at the primary disease site and required salvage total laryngectomy, and 2 patients (6%) had documented regional recurrence and required salvage neck dissection. Estimated 3-year progression-free survival and overall survival were 79% and 88%, respectively. No subjects required tracheostomy as a direct consequence of endoscopic resection. Patients who required tracheostomy before endoscopic resection due to either obstructive tumor bulk or unfavorable anatomy that precluded safe intubation (4 patients [12%]) were all decannulated in the early postoperative period (相似文献   

Partial laryngeal surgery in recurrent carcinoma

With the growing acceptance of nonsurgical therapies for laryngeal squamous cell carcinomas (LSCCs), it has become important to delineate surgical salvage strategies for disease recurrences. Total laryngectomy is often recommended, but appropriately selected laryngeal recurrences may be treated successfully with partial laryngeal surgery: laryngeal function can be preserved with oncological efficacy. The main available studies dealing with partial laryngeal surgery in recurrent carcinoma were critically reviewed. The most appealing feature of salvage transoral laser surgery (TLS) is the opportunity to make tumor-tailored excisions without any reconstructive limitations and retaining the option to switch to open partial laryngectomy. A recent detailed review of 11 series found a pooled local control rate of 57% after a first TLS procedure. Supracricoid laryngectomy (SCL) seems to achieve good local control rates in selected cases of recurrent supraglottic-glottic carcinoma: one review considering seven series calculated that 85% of the patients treated with salvage SCL after radiotherapy experienced no local recurrence; and total laryngectomy after failure of salvage SCL afforded an overall local control rate of 65%. Neck dissection is mandatory in all cases of local LSCC recurrence with evidence of neck metastases, and routine elective neck dissection is recommended for recurrent supraglottic and transglottic cancers.     

Results of conservation surgery for cancers of the supraglottis and pyriform sinus

A retrospective review of patients treated by surgery and/or radiation for carcinoma of the supraglottic larynx and the pyriform sinus was accomplished for the period 1964-1974. This patient population reflects the 10-year period following earlier experience with conservation surgery at this institution, and, thus, updates the current status of treatment for these cancers. Endpoints examined included survival, control, pattern of failure, the influence of nodal metastasis, and voice preservation. Of 160 patients treated for supraglottic laryngeal carcinoma, 119 received conservation surgery (subtotal supraglottic laryngectomy, SSL, or partial laryngopharyngectomy, PLP); 21 patients received total laryngectomy; and 20 others received palliative radiation. The 3-year actuarial survivals for these groups were 67%, 43% and 30%, respectively. Voice was preserved in 85% of the patients treated by conservation surgery, in 70% of those treated by radiation alone, and, of course, in none of the patients receiving total laryngectomy. There were 175 patients treated for carcinoma of the pyriform sinus; 85 received PLP; 57, total laryngopharyngectomy (TLP); and 33, palliative radiation. Actuarial 3-year survival was 59% for the PLP-treated group, 36% for the TLP-treated group and 11% for the palliation group. Voice was preserved in 52% of the patients treated by conservation surgery, in 6% of those treated by radiation alone, and in none of those patients treated by total laryngectomy. Comparison of this data with that in other published reports indicates that, for selected patients, conservation surgery is as effective in controlling disease as is radical surgery. Furthermore, it is possible to preserve speaking ability in a significant number of patients having carcinoma of the supraglottic larynx or pyriform sinus.     

The role of laser microsurgery in the treatment of laryngeal cancer

PURPOSE OF REVIEW: Transoral laser microsurgery has developed in recent years into a surgical method that combines a minimally invasive approach with the surgical precision of laser and microscope. The outcomes of laser microsurgical treatment of laryngeal carcinomas are reviewed and compared with the results of competitive standard procedures. RECENT FINDINGS: Laser microsurgery is widely acknowledged to have advantages in the treatment of early glottic carcinoma. In the treatment of glottic carcinoma causing impaired mobility or fixation of the vocal cord the role of laser surgery has not yet been definitively assessed. Based on published results, primary laser therapy can achieve local tumor control with a functional residual larynx in approximately 70-80% of cases. In patients with early or moderately advanced supraglottic carcinoma, laser microsurgery is comparable to open supraglottic laryngectomy in terms of local control and survival. With regard to organ preservation, laser microsurgery is comparable to open supraglottic laryngectomy but superior to radiotherapy. Microsurgery can preserve functionally important structures, allowing for early swallowing rehabilitation while avoiding tracheotomy. SUMMARY: This review elucidates the role of laser microsurgical partial resections of the larynx in comparison with other treatment modalities.     

Glandular carcinoma of the larynx: the UCLA experience.

Glandular carcinomas of the larynx are rare tumors that constitute less than 1% of all laryngeal malignancies. A retrospective case review of 12 patients with glandular carcinomas of the larynx is presented to identify patient and tumor characteristics, therapeutic modalities, and treatment outcomes. Ten patients underwent surgical excision of the primary tumor, by either supraglottic laryngectomy, vertical partial laryngectomy, or total laryngectomy. Seven of these patients also received postoperative radiotherapy. After a median follow-up period of 23 months, 7 of the 12 patients (58.3%) died as a result of uncontrolled locoregional disease or distant metastases. The 5-year survival rate was 57% in patients who underwent combination therapy versus 50% for those patients who received surgery alone. Surgical resection is the primary treatment modality used in the majority of cases. Neck dissection is reserved for patients with clinically apparent adenopathy, adenocarcinoma, or high-grade mucoepidermoid carcinoma. Combination therapy with surgical resection and radiotherapy may be more effective in achieving tumor remission than is surgical resection alone.     

Glottic cancer. Surgical salvage for radiation failure

Radiation therapy is a well-established treatment for early squamous cell carcinoma of the glottic larynx. However, the management of patients suspected to have persistent or recurrent disease may present both diagnostic and therapeutic dilemmas, particularly when laryngeal edema persists months after conclusion of radiation therapy. We reviewed the outcome of 212 patients with T1s, T1, and T2NOMO carcinoma of the glottic larynx who had been treated for cure with radiation therapy, with surgical salvage reserved for radiation failures. Twenty-four patients (11%) had recurrences after radiation therapy, 13 (59%) of whom had successful salvage by surgery. The five-year, recurrence-free survival in this series was 92% for T1s and T1 and 69% for T2. We conclude that T1s, T1, T2NOMO carcinoma of the glottic larynx is effectively managed by radiation therapy and surgical salvage for radiation failure. Total laryngectomy usually was necessary for surgical salvage.     

Partial laryngectomy for recurrent laryngeal carcinoma

From July 1975 to January 1998, 33 patients underwent partial laryngeal resection for residual or recurrent tumour after primary radical radiotherapy. Sixteen patients had T1 tumours on presentation, 14 were T2 and three were T3. Six patients underwent a supraglottic (horizontal) laryngectomy, 24 had a vertical partial laryngectomy, two had an endoscopic laser resection and one had an endoscopic laser resection followed by a vertical partial laryngectomy. The median time interval between radiotherapy and salvage surgery was 10 months (range 2-188 months). The median follow-up period was 41 months (range 12-185 months). There were five major postoperative complications (15%); two patients developed a pharyngeal fistula and three required further surgery for laryngo-tracheal stenosis. Twenty-five patients (76%) retained their larynx with satisfactory speech and swallowing. Eight patients (24%) had to be converted to a total laryngectomy, seven for recurrent disease and one for laryngeal stenosis. Of the eight patents converted, seven had normal swallowing and six developed good tracheo-oesophageal speech. Seven patients (21%) developed recurrent tumour after partial laryngectomy and were subjected to total laryngectomy; six of these seven were salvaged. Only one of the 33 patients died with recurrent tumour, giving an ultimate disease-related survival of 97%. Conservation laryngeal surgery for salvage of selected patients who fail radical radiation therapy is safe, effective, and results in reasonable preservation of laryngeal function.     

Laryngeal preservation by treatment with induction chemotherapy and radiotherapy protocol for stage III & IV carcinoma larynx--results of a pilot study.

Total laryngectomy for advanced carcinoma of the larynx is effective but functionally disabling. In an effort at laryngeal preservation, 33 patients of stage III/IV carcinoma larynx were treated between 1987 and 1991 with induction chemotherapy followed by definitive radiation. Two chemotherapy protocols were administered. Group I patients received one to three cycles of cisplatin 100 mg/m2 (day 1), bleomycin 15 U/m2 (day 1), and 5-fluorouracil 1000 mg/m2/day (day 2 to 5) at three weekly intervals. This was then followed by radiotherapy. Group II received one to six weekly injections of single agent methotrexate 50 mg/m2 with or without leucocovorin rescue followed by radiotherapy. Any recurrence was salvaged by surgery. Midway through the study, Group II protocol was discontinued as the initial results were not comparable with Group I or standard treatment. The Group I protocol, however, yielded an initial locoregional control rate of 83.3 per cent With the addition of surgical salvage the locoregional control rate was 94.4 per cent and the control rate with laryngeal preservation was 88.8 per cent. The Kaplan-Meier probability of two years and five years disease-free survival was 81.9 per cent and 61.4 per cent respectively. For disease-free survival with laryngeal preservation the corresponding figures for two years and five years were 58.3 per cent and 41.7 per cent. The control group of 51 patients treated with radical surgery followed by radiotherapy yielded survival figures at two years and five years of 64.3 per cent and 57.2 per cent. The difference in the survival of Group I and the control group was not statistically significant (p value = 0.280). These initial results indicate that for stage III and for surgically resectable stage IV laryngeal carcinomas, a protocol of induction combination chemotherapy consisting of cisplatin, bleomycin and 5-fluorouracil followed by radiotherapy and combined with surgical salvage whenever required, can lead to comparable cure rates. In addition, a large proportion of patients are spared the morbidity of a total laryngectomy.
