Conservation laryngeal surgery for selected pyriform sinus cancer

Comparison of Survival Outcomes Between Larynx-Preserving Open Partial Pharyngectomy and Radiotherapy or Chemoradiotherapy in Patients with Hypopharyngeal Squamous Cell Carcinoma: A Single-Center Retrospective Analysis with Inverse Probability of Treatment Weighting Adjustments

BACKGROUND

There is a group of hypopharyngeal squamous cell carcinoma (HPSCC) patients for whom larynx-preserving open partial pharyngectomy (PP) and radiotherapy/chemoradiotherapy (RT/CRT) are indicated. We aimed to retrospectively evaluate the survival difference as there is no evidence directly comparing the two therapies.

METHODS

This study evaluated HPSCC patients who were initially treated by PP or RT/CRT at our institution between January 2007 and October 2019. Overall survival (OS), disease-specific survival (DSS), laryngectomy-free survival (LFS), and local relapse-free survival (LRFS) were evaluated. The main analyses were performed with inverse probability of treatment weighting (IPTW) adjustments. Sensitivity analyses compared hazard ratios (HRs) obtained with three models: unadjusted, multivariate Cox regression, and propensity score-adjusted.

RESULTS

Overall, 198 patients were enrolled; 63 and 135 underwent PP and RT/CRT, respectively. IPTW-adjusted 5-year OS, DSS, LFS, and LRFS rates in the PP and RT/CRT groups were 84.3% and 61.9% (p = 0.019), 84.9% and 75.8% (p = 0.168), 94.8% and 90.0% (p = 0.010), and 75.9% and 74.1% (p = 0.789), respectively. In the IPTW-adjusted regression analysis, PP was associated with a significant benefit regarding OS (HR 0.48, 95% confidence interval [CI] 0.26-0.90) and LFS (HR 0.17, 95% CI 0.04-0.77). The results obtained with the three models in the sensitivity analyses were qualitatively similar to those of the IPTW-adjusted models.

CONCLUSION

Despite the risk of bias related to unadjusted factors, our results suggest that PP is associated with significantly better OS and LFS compared with RT/CRT for HPSCC.

Reconstruction of subtotal pharyngolaryngectomy using a fasciocutaneous free flap with cartilage graft: A case series of 17 patients

INTRODUCTION

Subcricoid-hemilaryngopharyngectomy (SCHLP) with a reconstruction using a fasciocutaneous free flap armed with cartilage graft (FFACG) aims to avoid permanent tracheostomy while still maintaining the laryngopharyngeal functions. The purpose of this study is to report the outcome of this surgical approach.

MATERIALS AND METHODS

Retrospective study including 17 men operated between 2001 and 2019. Specific survival rate included death caused by cancer or SCHLP complications. Complications, functional and oncological outcomes were evaluated retrospectively.

RESULTS

There were no locoregional recurrences. One patient died due to inhalation pneumonia 3 years after surgery. Tracheostomy was closed in 13 patients (76.5%). Mean decannulation time was at six [1-14] months after surgery.

CONCLUSION

SCHPL with FFACG could avoid total pharyngolaryngectomy with good oncologic results. However, tracheotomy is extended and deglutition recovery is long with high risk of aspirations. These complications justify that such surgery should be realized only on selected patients by experienced surgical teams. Expertise of the surgical team is critical.

Therapeutic effect on pyriform sinus carcinoma resection via paraglottic space approach

Objective

To analyse the surgical indications, surgical efficacy and key influencing factors of prognosis of using a novel surgical approach for pyriform sinus carcinoma resection utilising the paraglottic space.

Methods

From 2014 to 2017, 93 patients with squamous cell carcinoma originating in the pyriform sinus were resected through the paraglottic space approach. The postoperative laryngeal function preservation, complications, survival rate and prognostic factors were analysed.

Results

All patients were followed up for more than 5 years. The 2, 3 and 5 year overall survival rates of the patients were 77.2%, 61.6% and 47.4%, respectively. The univariate analysis of survival rate showed that primary tumour T stage and N stage had a statistically significant effect on the survival rate of patients (P = 0.047 and P < 0.001, respectively). Multivariate analysis with the Cox regression model revealed that N stage is an independent risk factor for postoperative survival (P = 0.042). The preservation rate of laryngeal function was 65.6% (61/93). Pharyngeal fistula incidence was 4.3% (4/93). Systemic distant metastasis and second primary cancer were found to be the main causes of death.

Conclusions

As a novel surgical approach for the resection of pyriform sinus carcinoma, the paraglottic space approach can better expose the tumour, effectively improve the retention rate of laryngeal function, reduce the incidence of pharyngeal fistula and result in the better recovery of postoperative swallowing function with satisfactory long-term survival. N stage is an independent risk factor for postoperative survival.

Efficacy of Larynx Preservation Surgery and Multimodal Adjuvant Therapy for Hypopharyngeal Cancer: A Case Series Study

Background: Larynx preservation surgery (LPS) combined with multimodal adjuvant therapy (MAT) is re-emerging as treatment option for hypopharyngeal cancer (HPC). This study aims to explore the survival and functional outcome of this combined approach. Methods: This is a retrospective cohort study. Selected patients with primary HPC treated by LPS and MAT at two large Beijing medical centers between 2005 and 2019 were included. In addition to LPS, patients received one or more of the following treatments: preoperative induction chemotherapy, postoperative intensity-modulated radiotherapy, chemotherapy, or targeted therapy. Results: In total, 64 patients were included (62 were men, and median age was 57.5 years). The disease in most patients was in stage III (28.1%) or IV (56.3%), or in stage T2 (34.4%) or T3 (45.3%), based on the TNM scale. Across all patients, the rate of overall survival (OS) was 60.7% at 3 yr and 47.3% at 5 yr. OS was significantly higher for patients with stage I or II disease than for those with stage III or IV disease (HR 8.64, 95% CI 3.69-20.2, log-rank P = .010). Decannulation was successful in 55 patients (85.9%), and swallowing function was satisfactory (stage 0-III, on Functional Outcome Swallowing Scale) for 50 (78.1%). Median Voice Handicap Index-10 score on voice performance was 19 (range 4-40), and median Functional Assessment of Cancer Therapy-General Questionnaire score for QoL was 75 (range 16-105). Conclusions: LPS and MAT can provide satisfactory oncologic control and good functional outcomes for selected patients with HPC, especially those with stage I or II disease.

Treatment results of 99 patients undergoing open partial hypopharyngectomy with larynx preservation

Objective

Hypopharyngeal cancers frequently go undetected until advanced stages. However, recent advances in endoscopic technology have enabled earlier detection of hypopharyngeal cancer. We evaluated the effectiveness of larynx-preserving surgery for hypopharyngeal cancer.

Methods

We retrospectively analyzed 99 patients with hypopharyngeal squamous cell carcinoma who underwent partial hypopharyngectomy with larynx preservation between September 1992 and December 2009 at the National Cancer Center Hospital East. Of these, 91 patients underwent larynx-preserving surgery as initial treatment; eight patients underwent salvage surgery for recurrent disease after previous radiotherapy. Also, 9 of our patients had undergone previous radiotherapy in the head and neck for a different cancer. Before surgery, the TNM stage and tumor location was recorded. Free-flap reconstruction was performed in 60 patients, while the hypopharyngeal mucosa was closed without a free flap in 39 patients.

Results

The 5-year overall survival rate in our cohort was 66.9%, and 59 patients are currently alive without recurrence. Thirty-three patients died due to primary recurrence (n = 5), regional recurrence (n = 10), distant metastasis (n = 9), postoperative death (n = 1), and unrelated disease (n = 8). Laryngeal function could not be preserved in 19 patients, 2 of whom had undergone previous radiotherapy, and 7 of whom had undergone both previous radiotherapy and other salvage surgeries.

Conclusion

Partial hypopharyngectomy can preserve laryngeal function in patients with pharyngeal cancer with careful patient selection.

Long-term oncological and functional outcomes of induction chemotherapy followed by (chemo)radiotherapy vs definitive chemoradiotherapy vs surgery-based therapy in locally advanced stage III/IV hypopharyngeal cancer: Multicenter review of 266 cases

OBJECTIVE

The aim of this study was to evaluate the treatment outcomes for stage III/IV locally advanced hypopharyngeal squamous cell carcinoma (SCC), comparing induction chemotherapy followed by (chemo)radiotherapy (ICT), definitive chemoradiotherapy (CRT) and surgery-based therapy (SRT).

SUBJECTS AND METHODS

Two hundred sixty-six patients with stage III/IV locally advanced hypopharyngeal squamous cell carcinoma (SCC) who underwent ICT (n = 74), CRT (n = 53) or SRT (n = 139) from 1997 through 2014 at the Seoul National University Hospital (n = 127) and the Hallym University Medical Center (n = 139) were enrolled in the study. All surgical procedures in the SRT group were performed by a single surgeon to eliminate surgeon bias.

RESULTS

The 5-year disease-free survival (DFS) and overall survival (OS) of all patients (n = 266) were 59.4% and 44%, respectively. The 5-year DFS rates after salvage treatment were 52.7% for ICT, 52.8% for CRT and 65.5% for SRT (p = 0.194). The OS rates were 44.6% for ICT, 39.6% for CRT and 45.3% for SRT group (p = 0.106). The salvage rates were 12.5% for ICT, 15.6% for CRT and 3.8% for SRT group. The final laryngeal preservation rate was significantly lower in the SRT group (44.6%) than in the ICT (71.6%) or CRT (71.7%) groups. All major postoperative complications were significantly higher in the salvage surgery group.

CONCLUSION

Treatment outcomes in the ICT and CRT groups were comparable to that of the SRT group for stage III/IV hypopharyngeal SCC. However, the relatively low chance of cure and high risk of complications should be taken into account when considering salvage surgery.

Open-neck organ preservation surgery for hypopharyngeal cancer: indications, techniques, limits, and outcomes

PURPOSE OF REVIEW

To appraise the practice and role of open-neck organ preserving surgery for hypopharyngeal squamous cell carcinoma and to update the current indications, techniques, limits, and outcomes.

RECENT FINDINGS

The role of primary surgery for hypopharyngeal carcinoma has shifted over the past two decades to primary nonsurgical management with the use of induction or concurrent chemoradiotherapy. The preferred and most suitable tumours for open-neck surgery are the small-volume T stage diseases, with small to medium-volume neck metastases, however such patients are exceedingly rare. Nonetheless, more advanced tumours with cartilage invasion, vocal cord paralysis, or located at piriform apex and postcricoid area, previously unsuitable for open-neck organ preserving surgery, can now be excised and repaired, minimizing morbidity and improving quality of patients' life. Much of this surgical progress has been developed by innovative surgeons using free tissue transfer, accurate placement surgery, reconstruction of a neoglottis, and perfecting the pharyngoesophageal anastomosis. Current practice of open-neck organ preserving surgery for hypopharyngeal carcinoma has been mainly reported in Asia: Korea, Taiwan, Japan, and China.

SUMMARY

There are some patients who are deemed unsuitable and/or unwilling for current treatment by nonsurgical approaches, and open-neck organ preserving laryngopharyngeal surgery may be a more suitable alternative than selecting a 'lesser or modified' chemo or bioradiotherapy regimen, resulting in a prolonged quantity and quality of life.

Oncological and Functional Evaluation of Open Conservation Surgery for Hypopharyngeal Cancer with/without Reconstruction

Objectives

Oncological and functional results of open conservation surgery for hypopharyngeal cancer have been desired.

Methods

We performed a chart review of 33 patients with hypopharyngeal cancer who underwent open conservation surgery. Oncological and functional results were evaluated in surgery with primary closure (Group A) and surgery with reconstruction (Group B). Postoperative functions were evaluated by interval to resumption of oral intake, Functional Outcome Swallowing Scale (FOSS) and Communication Scale (CS).

Results

Five-year disease-specific and overall cumulative survival rates by Kaplan-Meier method for all cases were 95.7% and 82.3%, respectively. Duration from surgery to full oral intake was 12 days in Group A and 14 days in Group B. FOSS rates were 83.3 in Group A and 95.5 in Group B. CS was 0 in both groups.

Conclusion

Oncological and functional results of open conservation surgery were comparable to those with transoral surgery and chemo/radiotherapy. Our technique represents a reliable treatment for hypopharyngeal cancer.

Early hypopharyngeal cancer treated with different therapeutic approaches: a single-institution cohort analysis

Purpose

Early hypopharyngeal squamous cell carcinoma (HPSCC) is a rarely diagnosed disease, for which the optimal treatment has not been defined yet. We assessed patterns of failure and outcomes in early HPSCC treated with various therapeutic approaches to identify its optimal treatment.

Materials and Methods

Thirty-six patients with stage I (n = 10) and II (n = 26) treated between January 1992 and March 2014 were reviewed. Patients received definitive radiotherapy (RT) (R group, n = 10), surgery only (S group, n = 19), or postoperative RT (PORT group, n = 7). All patients in both the R and PORT groups received elective bilateral neck irradiation. In the S group, 7 patients had ipsilateral and 8 had bilateral dissection, while 4 patients had no elective dissection.

Results

At a median follow-up of 48 months, the 5-year locoregional control (LRC) rate was 65%. Six patients had local failure, 1 regional failure (RF), 3 combined locoregional failures, and 2 distant failures. There was no difference in 5-year LRC among the R, S, and PORT groups (p = 0.17). The presence with a pyriform sinus apex extension was a prognosticator related to LRC (p = 0.01) in the multivariate analysis. Patients with a bilaterally treated neck showed a trend toward a lower RF rate (p = 0.08).

Conclusion

This study shows that patients with early stage HPSCC involving the pyriform sinus apex might need a tailored approach to improve LRC. Additionally, our study confirms elective neck treatment might have an efficacious role in regional control.

Primary radiotherapy for squamous cell carcinoma of the pyriform sinus

The objective of this study is to report the long-term outcomes of primary radiotherapy (RT) for patients with T1-T2 squamous cell carcinomas (SCC) of the pyriform sinus. Between November 1964 and March 2008, 135 patients with T1-T2 pyriform sinus SCC were treated with primary RT at the University of Florida. Adjuvant chemotherapy was employed in 21 patients (16 %) and 62 patients (46 %) underwent a planned neck dissection. Median follow-up was 3.5 years (range 0.2-24.7 years); median follow-up on living patients was 8.3 years (range 3.8-24.0 years). The 5-year outcomes were as follows: local control, 85 %; regional control, 81 %; local-regional control, 71 %; distant metastasis-free survival, 76 %; cause-specific survival, 62 %; and overall survival, 38 %. The 5-year local control rate was 88 % for T1 cancers and 84 % for those with T2 SCCs (p = 0.5429). Sixteen patients (12 %) experienced severe late complications. Primary RT results in a high probability of cure with a relatively modest risk of severe late complications for patients with T1-T2 SCCs of the pyriform sinus.

Hypopharynx and Larynx Defect Repair after Resection for Pyriform Fossa Cancer with a Platysma Skin Flap

We used a platysma skin flap to repair larynx and hypopharynx defects to improve postoperative laryngeal function in patients with pyriform fossa cancer. Larynx-sparing surgery and postoperative radiotherapy were used in 10 patients with pyriform fossa cancer. The surgical approaches of lymph node dissection of the neck, vertical partial laryngectomy, and pyriform fossa resection were adopted, and a platysma skin flap was used to repair the resulting defects. In this group, the overall 3-year survival rate was 75% according to the Kaplan-Meier analysis, and the local control rate was 90%. Additionally, all patients were able to speak fluently with mild-to-moderate hoarseness. The tracheal tube was removed in all cases. Laryngeal fistulas were observed in 1 patient during radiotherapy. In conclusion, a platysma skin flap can be used to rebuild the larynx and hypopharynx in larynx-sparing resection for pyriform fossa cancer. These patients can obtain good postoperative function in swallowing, breathing, and pronunciation.

Free posterior tibial flap reconstruction for hypopharyngeal squamous cell carcinoma

OBJECTIVES

The aim of this article was to determine outcomes in patients with squamous cell carcinoma of the hypopharynx (SCCHP) in whom the free posterior tibial flap was used for primary reconstruction of hypopharynx defects after cancer resection.

SUBJECTS AND METHODS

Between August 2009 and February 2012, 10 patients with SCCHP underwent posterior tibial flap reconstruction for hypopharynx defects. The corresponding clinical data were retrospectively collected and analyzed.

RESULTS

Despite the multistep and time-consuming procedure, the posterior tibial flap survival rate was 100%. Operation-induced complications did not occur in four patients. Six patients developed postoperative hypoproteinemia, four patients developed postoperative pulmonary infections, and four patients developed pharyngeal fistula. The pharyngeal and laryngeal functions of all patients were preserved.

CONCLUSION

Our experience demonstrates that the posterior tibial flap is a safe and reliable choice for the reconstruction of hypopharynx defects.

Conservation surgery for hypopharyngeal cancer: changing paradigm from open to endoscopic

CONCLUSIONS

Endoscopic laser microsurgery (ELM) provides comparable oncological outcomes, and improved functional recovery and laryngeal preservation compared with open partial laryngopharyngectomy (OPLP) in patients with early squamous cell carcinoma of the hypopharynx (HPSCC). The use of open surgery is declining. The outcome of the study provides evidence-based recommendations for surgical choices in HPSCC treatment. However, it is not conclusive without a larger prospective study.

OBJECTIVES

To compare the functional and oncological results of ELM and OPLP in HPSCC and examine surgical trends.

METHODS

From 1990 to 2008, 53 HPSCC patients undergoing ELM (n = 25) and OPLP (n = 28) were included. Functional recovery, oncological results, and laryngeal preservation rate were analyzed.

RESULTS

Patients who underwent ELM demonstrated a shorter decannulation period (7 vs 11 days, p = 0.010), time using a nasogastric tube (7 vs 16 days, p = 0.043), and hospitalization stay (12 vs 22 days, p = 0.0061) than those who underwent OPLP. The 3-year overall and disease-specific survival rates were comparable between ELM and OPLP (79% vs 64%, p = 0.151, and 83% vs 71%, p = 0.320, respectively). The ELM patients had better laryngeal preservation (92% vs 71%, p = 0.048). The number of OPLPs performed has decreased since 2000 (68% before vs 32% after, p < 0.0001).

Alternative treatment option for hypopharyngeal cancer: clinical outcomes after conservative laryngeal surgery with partial pharyngectomy

CONCLUSION

The oncological and functional outcomes of hypopharyngeal cancer after conservative laryngeal surgery are fairly acceptable, making this a reasonable initial treatment option for selected patients.

OBJECTIVE

The purpose of this study was to assess the clinical outcomes of patients with hypopharyngeal squamous cell carcinoma (SCC) treated with conservative laryngeal surgery with partial pharyngectomy.

METHODS

Fifty-eight patients with hypopharyngeal SCC who underwent laryngeal preservation surgery were enrolled. The tumors were classified as cT1 in 5 (8.6%) patients, cT2 in 35 (60.3%), cT3 in 14 (24.1%), and cT4a in 4 (6.9%) patients.

RESULTS

Surgical outcomes: 5-year overall and disease-specific survival rates were 78% and 77.6%. Recurrent disease developed in 13 patients (22.4%). Multivariate analysis revealed that level VI metastasis confirmed by histopathological analysis, close (< 5 mm) histologic margin, advanced N stage, and posterior pharyngeal wall tumor were independent factors associated with poor disease-specific survival. Functional outcomes: 50 patients (86.2%) could obtain all their nutritional needs orally. Eight patients needed the assistance of a percutaneous endoscopic gastrostomy tube. Oral re-alimentation was achieved within a mean of 26.1 days after surgery. Fifty-one patients (87.9%) could be decannulated after a mean of 43.8 days postoperatively.

Traditional transcutaneous approaches in head and neck surgery

The treatment of laryngeal and hypopharyngeal malignancies remains a challenging task for the head and neck surgeon as the chosen treatment modality often has to bridge the gap between oncologically sound radicality and preservation of function. Due to the increase in transoral laser surgery in early tumor stages and chemoradiation in advanced stages, the usage of traditional transcutaneous approaches has decreased over the recent past. In addition, the need for a function-sparing surgical approach as well as highest possible quality of life has become evident. In view of these facts, rationale and importance of traditional transcutaneous approaches to the treatment of laryngeal and hypopharyngeal malignancies are discussed in a contemporary background. The transcutaneous open partial laryngectomies remain a valuable tool in the surgeon's armamentarium for the treatment of early and advanced laryngeal carcinomas, especially in cases of impossible laryngeal overview using the rigid laryngoscope. Open partial laryngetomies offer superior overview and oncologic safety at the anterior commissure, especially in recurrencies. In select advanced cases and salvage settings, the supracricoid laryngectomy offers a valuable tool for function-preserving but oncologically safe surgical therapy at the cost of high postoperative morbidity and a very demanding rehabilitation of swallowing.In hypopharyngeal malignancies, the increasing use of transoral laser surgery has led to a decline in transcutaneous resections via partial pharyngectomy with partial laryngectomy in early tumor stages. In advanced stages of tumors of the piriform sinus and the postcricoid area with involvement of the larynx, total laryngectomy with partial pharyngectomy is an oncologically safe approach. The radical surgical approach using circumferent laryngopharyngectomy with/without esophagectomy is indicated in salvage cases with advanced recurrences or as a primary surgical approach in patients where chemoradiation does not offer sufficient oncologic control or preservation of function. In cases with impending reconstruction, fasciocutaneous free flaps (anterolateral thigh flap, radial forearm flap) seem to offer superior results to enteric flaps in cases where the cervical esophagus is not involved leading to better voice rehabilitation with fewer complications and postoperative morbidity. In salvage situations, the Gastroomental Free Flap has proven to be a valuable tool.In conclusion, the choice of a surgical treatment modality is influenced by the patient's anatomy, tumor size and location as well as the surgeon's personal expertise.

Partial laryngopharyngectomy in the treatment of squamous cell carcinoma of hypopharynx: analysis of the oncologic results and laryngeal preservation rate

CONCLUSION

Partial laryngopharyngectomy (PLP) provides acceptable oncologic results and laryngeal preservation rate in selected patients with squamous cell carcinoma of the hypopharynx. Even when local recurrence develops, the chance of successful salvage is still high.

OBJECTIVES

To evaluate the oncologic results and laryngeal preservation rate in patients with squamous cell carcinoma of the hypopharynx who underwent PLP.

METHODS

The results of 39 patients who underwent PLP were compared with those of 91 patients who underwent total laryngectomy (TL).

RESULTS

The distribution of the primary T stages were 23 (59%) pT2, 9 (23%) pT3, and 7 (18%) pT4; the pathologic stages were 8 patients (21%) stage II, 9 (23%) stage III, and 22 (56%) stage IV. All of the patients also had ipsilateral or bilateral neck dissections. Eighteen patients (46%) received postoperative adjuvant therapy. After a median follow-up of 39 months, 17 patients (44%) had recurrence, including 12 local, 2 regional, and 3 distant lesions. The 5-year overall and disease-specific survival were 44% and 56%, respectively; functional preservation was 62%. The recurrence rate was similar in patients treated with PLP and TL (44% vs 36%, p = 0.431); the local recurrence rate was higher after PLP than after TL (31% vs 8%, p = 0.001). The salvage surgery was successful in four of the six patients (67%). After salvage treatment, the 5-year overall survival (44% vs 47%) and disease-specific survival (56% vs 62%) were similar in the two groups.

Radiotherapy for stage I or II hypopharyngeal carcinoma

Hypopharyngeal squamous cell carcinoma (HPSCC) is usually diagnosed at an advanced stage, and early-stage HPSCC is relatively rare. Because of the rarity of early-stage HPSCC, few reports have been published on the efficacy of radiotherapy (RT) in its treatment. We retrospectively reviewed the clinical records of 45 consecutive patients with Stage I and II HPSCC from May 1991 to June 2010. Patient characteristics were as follows: median age, 66 years (range, 44-90 years); male/female, 39/6; and T1/T2, 27/18. The irradiation dose ranged from 60 to 72 Gy (median: 70 Gy). Of the 45 patients, 21 underwent concurrent chemotherapy. With a median follow-up period of 62 months, the 5-year overall survival rate was 81%. Local failure occurred in 5 patients, and the 5-year local control rate was 83%. All local recurrences were successfully salvaged by surgery. The 5-year functional larynx preservation rate was 92%. Acute toxicity was manageable. Grade 3 laryngeal edema and Grade 3 hypothyroidism occurred in 1 patient each. No other late adverse events of Grade 3 or greater were observed. Based on these results, RT seemed to be an effective treatment modality for early HPSCC, with favorable organ preservation and acceptable adverse events. Early detection and accurate management of local recurrence and second malignancy was deemed to be critical.

Extended voice-sparing surgery in selected pyriform sinus carcinoma: techniques and outcomes

BACKGROUND

Organ-preservation approaches are frequently favored in the treatment of advanced pyriform sinus carcinoma. In selected cases, use of free flaps allows voice-sparing surgery.

METHODS

Thirteen patients underwent conservative extended laryngopharyngectomy. In 11 patients, the resection included the supraglottic larynx, whereas the whole hemilarynx was resected in 2. Reconstruction was achieved with a radial forearm free flap with the palmaris longus tendon. In hemilarynx resection, a costal graft was also used. Functional results were assessed by nasofibroscopy and swallowing videofluoroscopic tests.

RESULTS

At 12 months, no patient was gastrostomy dependent, whereas 1 patient remained tracheostomy dependent. At 1, 3, and 5 years, the locoregional control was 100%, 100%, and 83%; overall survival was 69.4%, 46.3%, and 30.8%; and disease-specific survival was 81.2%, 54.5%, and 36.4%, respectively.

CONCLUSIONS

In selected patients, extended conservative laryngopharyngectomy challenges the oncologic results of organ-preservation protocols and allows a good quality of life.

Role of larynx-preserving partial hypopharyngectomy with and without postoperative radiotherapy for squamous cell carcinoma of the hypopharynx

The purpose of this study was to examine the treatment outcomes of larynx-preserving partial hypopharyngectomies for hypopharyngeal carcinoma. Forty-three patients underwent partial hypopharyngectomy and reconstruction using faciocutaneous free flaps with and without postoperative radiotherapy between 1998 and 2009. Primary tumor sites were pyriform sinus in 35 and posterior pharyngeal wall in 8 patients. Thirty patients received postoperative radiotherapy. The 5-year overall and disease-specific survival rates were 63% and 67%, respectively. A significant positive correlation was found between pathologic N stage and primary site and disease-specific survival rates (N0/N1 stage; 93% vs. N2/N3 stage; 43%, p<0.001 and pyriform sinus; 80% vs. posterior pharyngeal wall; 29%, p=0.012, respectively). Recurrences occurred in 15 (35%) patients. Among them, two patients were successfully rescued. Primary partial hypopharyngectomy with laryngeal preservation can be achieved with favorable oncologic outcomes. Factors that affected prognosis were advanced stage neck disease and posterior pharyngeal wall carcinoma.

Current trends in initial management of hypopharyngeal cancer: the declining use of open surgery

Squamous cell carcinoma of the hypopharynx represents a distinct clinical entity. Most patients present with significant comorbidities and advanced-stage disease. The overall survival is relatively poor because of high rates of regional and distant metastasis at presentation or early in the course of the disease. A multidisciplinary approach is crucial in the overall management of these patients to achieve the best results and maintain or improve functional results. Traditionally, operable hypopharyngeal cancer has been treated by total (occasionally partial) laryngectomy and partial or circumferential pharyngectomy, followed by reconstruction and postoperative radiotherapy in most cases. Efforts to preserve speech and swallowing function in the surgical treatment of hypopharyngeal (and laryngeal) cancer have resulted in a declining use of total laryngopharyngectomy and improved reconstructive efforts, including microvascular free tissue transfer. There are many surgical, as well as nonsurgical, options available for organ and function preservation, which report equally effective tumor control and survival. The selection of appropriate treatment is of crucial importance in the achievement of optimal results for these patients. In this article, several aspects of surgical and nonsurgical approaches in the treatment of hypopharyngeal cancer are discussed. Future studies must be carefully designed within clearly defined populations and use uniform terminology and standardized functional assessment and declare appropriate patient or disease endpoints. These studies should focus on improvement of results, without increasing patient morbidity. In this respect, technical improvements in radiotherapy such as intensity-modulated radiotherapy, advances in supportive care, and incorporation of newer systemic agents such as targeted therapy, are relevant developments.

Fasciocutaneous free flap reconstruction for squamous cell carcinoma of the hypopharynx

The purpose of this study was to examine functional and surgical outcomes after fasciocutaneous free flap reconstruction of the hypopharynx. A retrospective review of the records of 48 consecutive patients that underwent hypopharyngectomy and reconstruction using fasciocutaneous free flaps between 1996 and 2009 was performed. Flap donor sites included the radial forearm (n = 42), anterolateral thigh (n = 5), and lateral thigh (n = 1). There was no perioperative mortality, and the free flap survival rate was 95.8%. Five (10.4%) patients developed a postoperative pharyngocutaneous fistula. In three (6.3%) patients a stricture developed during the postoperative period. Forty-four (92%) patients were decannulated and maintained their voice. Forty-four (92%) patients were able to take oral nutrition, although 4 (8%) needed additional PEG-tube feeding. Five-year overall and disease-specific survival rates were 56 and 61%, respectively. Functional reconstruction of extensive laryngohypopharyngeal defects can be achieved using fasciocutaneous free flaps with favorable functional and surgical results.

A structured review and theme analysis of papers published on ‘quality of life’ in head and neck cancer: 2000–2005

Over the past 10 years, quality of life (QOL) has been increasingly recognised as an important outcome parameter in head and neck cancer. Validated questionnaires have emerged and there has been an increase in the number of papers published each year. The aim of this article is to review the literature over the past five years (2000-2005 inclusive), to identify papers reporting outcomes using patient self-competed questionnaires and group these into themes. The tabulated summary allows for the areas of health related quality of life research to be identified and to explore issues that are perhaps deficit in the literature. The three authors independently searched the literature published in the English language using the ISI search engine with cross-reference using Pub Med and Ovid. The search terms were; quality of life, questionnaire, and head and neck cancer. Studies were placed in to one of five themes. There were 165 studies identified. The numbers in each theme were predictors of QOL [Hassanein KA, Musgrove BT, Bradbury E. Functional status of patients with oral cancer and its relation to style of coping, social support and psychological status. Br J Oral Maxillofac Surg 2001;39:340-5.], functional outcome [Klug C, Neuburg J, Glaser C, Schwarz B, Kermer C, Millesi W.

The evolving role of surgery in the management of head and neck tumors

PURPOSE OF REVIEW

This paper reviews recent surgical contributions to the multidisciplinary approach to head and neck cancer treatment as well as published data on pertinent questions in the field.

RECENT FINDINGS

The role of surgery in the strategy of organ preservation via chemoradiation, including treatments of complications and locoregional recurrences, such as when N1-N3 necks should be operated on and the role of CT and positron emission tomography (PET) scanning. Also covered are the role of sentinel lymph node biopsy for the detection of occult micrometastases in the N0 neck and the value of fluorodeoxyglucose PET scanning combined with the former. Transoral laser surgery for tumors of the larynx or of the hypopharynx is discussed, as is a new technique of reconstruction involving the anterolateral thigh free flap. Also included are quality of swallowing after resections and reconstruction of the oral cavity and orpharyngeal tumors.

SUMMARY

Surgery must define its role in the multidisciplinary treatment of advanced cancers, which currently often favors (chemo)radiotherapy protocols. Organ sparing by transoral laser surgery for laryngeal and hypopharyngeal cancer has established itself within our armamentarium and its exact role will be further refined. Larger and well-executed studies on sentinel lymph node biopsy in the clinically negative neck are needed before this procedure can be implemented in our routines. The latest addition, the anterolateral thigh flap, to further decrease patients' morbidity is unlikely to completely replace the currently favored radial forearm flap in soft tissue replacement of the head and neck. Outcome analysis, including swallowing, is a major step that surgeons should further investigate.
