Larynx Preservation Strategy Research Articles

Is precision medicine the solution to improve organ preservation in laryngeal/hypopharyngeal cancer? A position paper by the Preserve Research Group.

In locally advanced (LA) laryngeal/hypopharyngeal squamous cell carcinoma (LHSCC), larynx preservation (LP) strategies aim at the cure of the disease while preserving a functional larynx, thus avoiding total laryngectomy and the associated impact on the quality of life. In the last decades, apart from transoral and open-neck organ preservation approaches, several non-surgical regimens have been investigated: radiotherapy alone, alternate, concurrent or sequential chemoradiation, and bioradiotherapy. Despite major progress, the identification of reliable and effective predictors for treatment response remains a clinical challenge. This review examines the current state of LP in LA-LHSCC and the need for predictive factors, highlighting the importance of the PRESERVE trial in addressing this gap. The PRESERVE trial represents a pivotal initiative aimed at finding the optimal therapy for laryngeal preservation specific to each patient through a retrospective analysis of data from previous LP trials and prospectively validating findings. The goal of the PRESERVE trial is to develop a comprehensive predictive classifier that integrates clinical, molecular, and multi-omics data, thereby enhancing the precision and efficacy of patient selection for LP protocols.

Comparison of the efficacy of carelizumab combined with chemotherapy and chemotherapy alone in the induction therapy of locally advanced hypopharyngeal carcinoma

Objective: To compare the efficacy and safety of carrelizumab combined with the modified TPF regimen (docetaxel, cisplatinand capecitabine) and TPF regimen alone in larynx preservation strategy for locally advanced resectable hypopharyngeal squamous cell carcinoma. Methods: A cohort study was conducted. Patients with locally advanced resectable hypopharyngeal carcinoma (cT3-4aN0-3bM0) who were treated at the Eye & ENT Hospital of Fudan University from January 2017 to April 2023 were enrolled in the study. One group was treated with a modified TPF regimen (TPF group) for 2-3 cycles (retrospective data), and the other group was a prospective phase Ⅱ trial with a modified TPF regimen combined with carrelizumab (TPFC group) for three cycles. The patients with complete or partial remission of the primary focus were treated with sequential radical radiotherapy and/or drug therapy. The patients in the TPFC group were treated with carrelizumab at the end of radiotherapy with a maximum of up to 18 doses. The patients with stable or progressive disease were given radical surgery, and those who refused the surgery were given radical chemoradiotherapy. Objective response rate (ORR), overall survival rate, progression-free survival (PFS) rate, larynx preservation rate (LPR), and adverse reactions were compared between the two groups. Results: There were 51 male patients in the TPFC group, with an median age of 57 (35, 69) years. Meanwhile, 44 patients were in the TPF group, among which 43 were male and one was female, with an median age of 62 (46, 70) years. The ORR of the TPFC group was higher than that of the TPF group [82.4% (42/51) vs 63.6% (28/44), P=0.039]. During a median follow-up of 24.4 (18.5, 31.4) months, the TPFC group showed a higher 2-year survival rate (84.8% vs 64.6%, P=0.013) and 2-year LPR (66.6% vs 48.6%, P=0.045) than those in the TPF group. In patients with poor effect of induction therapy for hypopharyngeal carcinoma, surgical combination therapy significantly prolonged the 2-year PFS rate (77.9% vs 18.2%, P<0.001) and 2-year survival rate (76.9% vs 45.5%, P=0.005)than those of non-surgical combination therapy. The incidences of nausea and/or vomiting, reactive cutaneous capillary endothelial proliferation, thyroid dysfunction, and rash were increased in the TPFC group (all P<0.05). There was no treatment-related death. Conclusion: Carrelizumab combined with a modified TPF regimen has good efficacy and safety and can improve the LPR of locally advanced hypopharyngeal carcinoma.

Comparison of different laryngeal preservation strategies based on chemoradiotherapy in locally advanced hypopharyngeal carcinoma

Objective:This study aimed to evaluate the clinical features and treatment outcomes of the value of response-adapted treatment following radiotherapy and induction chemotherapy follwing subsequent comprehensive therapy in patients with resectable locally advanced hypopharyngeal carcinoma. Methods:This cohort study was conducted from September 2010 to September 2020 in our hospital, 231 patients pathologically confirmed stage Ⅲ and ⅣB resectable locally advanced hypopharyngeal carcinoma included. For the IC-directed ART strategy, IC is used to select good candidates to receive radical RT or CCRT, and others undergo surgery. He response-adapted strategy was determined based on the primary tumor response, which was evaluated at a dose of 50 Gy. If the response reached complete response or partial response（more than 80% tumor regression）, patients received radical RT or CCRT; otherwise, they received surgery, if possible, at 4 to 6 weeks after RT. The end points of the study were OS（overall survival）, progression free survival（PFS）, locoregional recurrence-free survival（LRRFS） and LDFS. Results:In IC-directed group, 75.0%（57/76） patients reached PR after 2 cycles of induction chemotherapy. While in RT-directed group, 70.3%（109/155） patients reached large PR at dose of 50 Gy. The median interquartile range follow-up period of the whole cohort was 63.8 months. The 5-year OS, PFS, LRRFS and SFL of the whole cohort were 47.9%、39.6%、44.3% and 36.2%, respectively. In evaluations based on the different treatment strategies, the 5-year OS and SFL were 51.3% versus 37.0%（HR 0.67; 95%CI 0.43-1.05; P=0.07） and 27.8% versus 39.8%（HR 0.68; 95%CI 0.46-0.99; P=0.04） between IC-directed and RT-directed groups. In additional, surgery complications did not significantly differ between these two groups. Conclusion:In this cohort study, the response-adapted strategy based on an early RT response facilitated better treatment tailoring, and higher laryngeal preservation compared with IC-directed strategies. This approach could provide a feasible laryngeal preservation strategy in patients with resectable locally advanced hypopharyngeal carcinoma.

Response-Adapted Treatment Following Radiotherapy in Patients With Resectable Locally Advanced Hypopharyngeal Carcinoma

Laryngeal preservation strategies for resectable locally advanced hypopharyngeal carcinoma (LAHPC) have been explored. However, the optimal strategy remains unclear. To evaluate a response-adapted strategy based on an early response to radiotherapy (RT) in patients with resectable LAHPC. This cohort study was conducted from May 2009 to October 2019 with a median (IQR) follow-up period of 66.5 (44.7-97.0) months. The study was conducted at a tertiary academic medical center and included 423 patients pathologically confirmed stage III and IVB LAHPC. A total of 250 patients with previous cancer history, synchronous primary cancer, stage I or II, or with unresectable hypopharyngeal carcinoma were excluded. Patients who reached 80% or greater tumor regression when evaluated endoscopically and by imaging methods at 50 Gy received definitive RT or concurrent chemoradiotherapy, and those with less than 80% regression underwent surgery 4 to 6 weeks after RT. Five-year overall survival and survival with a functional larynx. Overall, 423 patients were included in the study (median [IQR] age, 55 [50-63] years; 408 [96.5%] men and 15 [3.5%] women). The response-adapted and primary surgery groups had significantly better survival than the primary RT group (52.7% and 54.4% vs 27.7%, respectively; P < .001). The response-adapted and primary surgery groups had similar 5-year overall survival of 52.7% vs 54.4%, respectively (hazard ratio [HR], 1.02; 95% CI, 0.75 to 1.39; P = .89). The response-adapted group had better 5-year survival with functional larynx than the primary surgery group (40.6% vs 33.9%; HR, 0.64; 95% CI, 0.49 to 0.84, P = .001). Surgery complications did not significantly differ between the 2 groups. Among patients in the response-adapted group who required total laryngectomy (n = 186) as indicated by pretreatment evaluation, the 5-year cumulative Kaplan-Meier survival with functional larynx was 39.8%. In this cohort study, the response-adapted strategy based on an early RT response facilitated better treatment tailoring, maximum tumor control, and higher laryngeal preservation compared with primary surgery and primary RT strategies. This approach could provide a feasible laryngeal preservation strategy in patients with LAHPC.

A 10-Year Study on Larynx Preservation Compared With Surgical Resection in Patients With Locally Advanced Laryngeal and Hypopharyngeal Cancers.

BackgroundFew reports from China provide confirmed evidence of the effectiveness of the larynx preservation strategy compared with surgery on the treatment of laryngeal and hypopharyngeal cancers. This study assessed the clinical outcomes of patients with locally advanced laryngeal and hypopharyngeal cancers treated with larynx preservation and determined the optimal larynx preservation procedure.MethodsData of 1,494 patients treated with total laryngectomy or larynx preservation between 2006 and 2014 were retrieved from the database of Sun-Yat Sen University Cancer Center in Guangzhou, China, and 366 eligible patients were selected for final analysis. The clinical outcomes of 228 patients received total laryngectomy and 138 patients received larynx preservation treatments, which comprises induction followed by radiotherapy and concurrent radio-chemotherapy, were compared.ResultsThere was no statistical difference in the 3-, 5-, and 10-year PFS and OS in patients received larynx preservation compared with patients treated with laryngectomy. With respect to T stage, a better overall OS in T2-stage disease (P = 0.036) but poorer PFS (P = 0.005) in T3-stage disease was observed in the larynx preservation group compared with the surgery group in Univariate analysis. T3-stage disease had poorer PFS in multivariable analysis (P = 0.022). With larynx preservation intent, induction chemotherapy followed by radiotherapy showed no advantage in the control of disease progression and survival compared with concurrent chemoradiotherapy. The patient subpopulations who received efficacy assessment after induction chemotherapy exhibited significantly longer PFS and OS compared with those without efficacy assessment.ConclusionsThis is the largest sample size study on larynx preservation treatment for laryngeal and hypopharyngeal cancers in China. Our results indicated that larynx preservation treatments did not jeopardize the survival of patients with advanced resectable laryngeal or hypopharyngeal cancers. Efficacy assessment should be emphasized in induction chemotherapy.

Neoadjuvant Chemoradiotherapy and Larynx-Preserving Surgery for Cervical Esophageal Cancer.

Neoadjuvant concurrent chemoradiotherapy (CCRT) followed by surgery is widely used for treating locally advanced esophageal cancer in the thorax. This study evaluated the feasibility of neoadjuvant CCRT as a larynx preservation strategy for treating cervical esophageal squamous cell carcinoma (SCC) by a multidisciplinary team. Fifteen patients with cervical esophageal SCC who received neoadjuvant CCRT and radical surgery at our institution were reviewed. All patients received CCRT using the intensity-modulated radiation therapy with 48 Gy to gross tumor and 43.2 Gy to regional lymphatic basin in 24 fractions. Side effects, clinical tumor responses, pathological responses, and surgical margin status were analyzed. Pathological T down-staging was noted in seven patients (46.7%); pathological complete response was achieved in three patients (20%). Fourteen patients (93.3%) had larynx preservation; eight patients (53.3%) achieved negative surgical margins. The 2-year overall survival, local relapse-free survival, and regional relapse-free survival were 50.6%, 62.2%, and 47.5%, respectively. Neoadjuvant CCRT and larynx-sparing surgery are feasible and tolerable in patients with cervical esophageal SCC. Prospectively designed studies for large patient groups and long-term follow-up results are needed for validating this multimodality therapy.

Outcomes of Tumour Control from Primary Treatment of Hypopharyngeal Cancer.

Hypopharynx cancer continues to pose a clinically challenging head and neck subsite, driven not only by the unique set of patient, anatomic and disease factors but also by the paucity of robust clinical data to guide clinical decision making. The standard of care of radical surgery (pharyngolaryngectomy) in combination with postoperative radiotherapy was the previously accepted norm in the setting of advanced hypopharynx cancer, but this was often at the expense of significant morbidity. In the absence of survival benefit for advanced staged disease with radical surgical approaches, over the last 2 decades, the philosophy of quality of life in survivors has driven the agenda for new therapeutic approaches. The adoption of functional larynx preservation strategies has seen a paradigm shift in the treatment of this subsite since the 1990s with the advent of chemoradiation and intensity-modulated radiotherapy, thereby introducing a reducing trend for radical surgery. However, radical surgery (pharyngolaryngectomy) has a role in the non-functioning larynx (either pre- or post-treatment), in advanced volume disease and the more technically challenging salvage setting because of residual or recurrent disease. In earlier stage disease, transoral laser microsurgery and robotic surgery have shown good oncological benefits. Crucially, determining appropriate personalised treatment decisions in this challenging cohort of patients requires discussion within a multidisciplinary team framework.

Comparison of Treatment Outcomes for T3 Glottic Squamous Cell Carcinoma: A Meta-Analysis.

Objectives This study compared the survival outcomes, local control rate, and laryngeal preservation rate of various treatment strategies in the treatment of T3 squamous cell carcinoma of the glottis using proportional meta-analyses.Methods Twenty-five retrospective case-series studies were included in these analyses. Treatment strategies were classified as total laryngectomy (TL), open partial laryngectomy (PL), transoral laser microsurgery (TLM), chemo-radiation therapy (CRT), and radiation therapy (RT) alone.Results The overall survival rate and disease-specific survival rate among laryngeal preservation treatments did not differ from the overall survival rate of TL. However, the local control rate was lower with RT than TL and PL, and laryngeal preservation rates of TLM and CRT were higher than RT alone.Conclusion Consideration of preservation of laryngeal function is necessary when treating T3 glottic squamous cell carcinoma. PL, TLM, and, CRT are considered more appropriate initial laryngeal preservation strategies if available.

Three-dimensional imaging assessment of anatomic invasion and volumetric considerations for chemo/radiotherapy-based laryngeal preservation in T3 larynx cancer

ObjectivesTo investigate the impact of 3-Diminsional (3D) tumor volume (TV) and extent of involvement of primary tumor on treatment outcomes in a large uniform cohort of T3 laryngeal carcinoma patients treated with nonsurgical laryngeal preservation strategies. Materials and MethodsThe pretreatment contrast-enhanced computed tomography images of 90 patients with T3 laryngeal carcinoma were reviewed. Primary gross tumor volume (GTVp) was delineated to calculate the 3D TV and define the extent of invasion. Cartilage and soft tissue involvement was coded. The extent of invasion was dichotomized into non/limited invasion versus multiple invasion extension (MIE), and was subsequently correlated with survival outcomes. ResultsThe median TV was 6.6 cm3. Sixty-five patients had non/limited invasion, and 25 had MIE. Median follow-up for surviving patients was 52 months. The 5-year local control and overall survival rates for the whole cohort were 88% and 68%, respectively. There was no correlation between TV and survival outcomes. However, patients with non/limited invasion had better 5-year local control (LC) than those with MIE (95% vs 72%, p = .009) but did not have a significantly higher rate of overall survival (OS) (74% vs 67%, p = .327). In multivariate correlates of LC, MIE maintained statistical significance whereas baseline airway status showed a statistically significance trend with poor LC (p = .0087 and 0.06, respectively). Baseline good performance status was an independent predictor of improved OS (p = .03) in multivariate analysis. ConclusionThe extent of primary tumor invasion is an independent prognostic factor of LC of the disease after definitive radiotherapy in T3 larynx cancer.

Use of Larynx-Preservation Strategies in the Treatment of Laryngeal Cancer: American Society of Clinical Oncology Clinical Practice Guideline Update Summary.

Use of Larynx-Preservation Strategies in the Treatment of Laryngeal Cancer: American Society of Clinical Oncology Clinical Practice Guideline Update.

Purpose To update the guideline recommendations on the use of larynx-preservation strategies in the treatment of laryngeal cancer. Methods An Expert Panel updated the systematic review of the literature for the period from January 2005 to May 2017. Results The panel confirmed that the use of a larynx-preservation approach for appropriately selected patients does not compromise survival. No larynx-preservation approach offered a survival advantage compared with total laryngectomy and adjuvant therapy as indicated. Changes were supported for the use of endoscopic surgical resection in patients with limited disease (T1, T2) and for initial total laryngectomy in patients with T4a disease or with severe pretreatment laryngeal dysfunction. New recommendations for positron emission tomography imaging for the evaluation of regional nodes after treatment and best measures for evaluating voice and swallowing function were added. Recommendations Patients with T1, T2 laryngeal cancer should be treated initially with intent to preserve the larynx by using endoscopic resection or radiation therapy, with either leading to similar outcomes. For patients with locally advanced (T3, T4) disease, organ-preservation surgery, combined chemotherapy and radiation, or radiation alone offer the potential for larynx preservation without compromising overall survival. For selected patients with extensive T3 or large T4a lesions and/or poor pretreatment laryngeal function, better survival rates and quality of life may be achieved with total laryngectomy. Patients with clinically involved regional cervical nodes (N+) who have a complete clinical and radiologic imaging response after chemoradiation do not require elective neck dissection. All patients should undergo a pretreatment baseline assessment of voice and swallowing function and receive counseling with regard to the potential impact of treatment options on voice, swallowing, and quality of life.

Place de la chimiothérapie d’induction dans le traitement des carcinomes épidermoïdes des voies aérodigestives supérieures : contre

The treatment of locally advanced head and neck squamous cell carcinoma is based on concomitant chemoradiotherapy. A sequential treatment combining induction chemotherapy with docetaxel, cisplatin and 5-fluorouracil (TPF), followed by (chemo)radiotherapy is frequently used as part of laryngeal preservation strategies. Apart from this particular situation, the benefit in terms of survival of induction chemotherapy has been much discussed in recent years. In five recent randomized trials, chemoradiotherapy was compared with TPF induction chemotherapy followed by chemoradiotherapy. Of these five trials, four concluded that these treatments were similar. A single trial reports a benefit for induction chemotherapy but its methodology is highly debatable. After TPF chemotherapy, chemoradiotherapy is less well tolerated. In patients with significant lymph node invasion (N2b-c-N3), induction chemotherapy reduces the occurrence of distant metastasis. The HPV status should not influence the therapeutic decision.

Locally advanced laryngeal cancer. Larynx preservation strategies

Larynx preservation in locally advanced laryngeal cancer is intended to obtain cancer control and, if possible, the preservation of laryngeal anatomy and functions (speech, swallowing and airway patency). Eligibility criteria for larynx preservation strategies are medical and surgical. Medical factors include age, performance status, nutrition status and visceral functions. Surgical factors are local factors on which depends tumor resectability and post-treatment larynx functionality. Larynx preservation strategies include radiotherapy as local treatment associated with concomitant or sequential chemotherapy. Concomitant cisplatin-fluorouracil (CDDP-FU or PF) chemoradiation and docetaxel-cisplatin-fluorouracil (TPF) induction chemotherapy followed by radiation therapy increased larynx preservation and are evidence-based validated options. After TFP (docetaxel-CDDP-FU) induction chemotherapy, cetuximab-based immunotherapy with concomitant irradiation showed no superiority to concurrent cisplatin-based chemo-radiotherapy and, consequently, this combination should not be used, except for unfit patients to platinum-based regimen.

A comparison of overall survival for patients with T4 larynx cancer treated with surgical versus organ-preservation approaches: A National Cancer Data Base analysis.

Although laryngectomy is the treatment of choice for patients with T4 larynx cancer, many patients are unable or unwilling to undergo laryngectomy and instead pursue larynx-preservation strategies combining radiotherapy (RT) and chemotherapy. Herein, the authors analyzed the National Cancer Data Base to evaluate overall survival (OS) between patients treated with surgical and organ-preserving modalities. The National Cancer Data Base was queried for patients diagnosed from 2004 through 2012 with T4M0 laryngeal cancer who underwent either laryngectomy (surgery) with adjuvant RT (SRT), chemotherapy starting concurrently within 7 days of RT (CCRT), or multiagent induction chemotherapy starting 43 to 98 days before RT (ICRT). Multivariate analysis and propensity score matching were used to explore the association between the intervention and OS. Recursive partitioning analysis was performed to identify groups benefiting from particular modalities. A total of 1559 patients who underwent SRT, 1597 patients who underwent CCRT, and 386 patients who underwent ICRT were included. Adjusting for covariates, CCRT was found to be associated with inferior OS compared with SRT (hazard ratio [HR], 1.55; 95% confidence interval [95% CI], 1.41-1.70 [P<.01]) and with ICRT (HR, 1.25; 95% CI, 1.07-1.45 [P<.01]). OS among the patients treated with SRT did not appear to differ significantly from that of the ICRT cohort (HR, 0.87; 95% CI, 0.73-1.03 [P = 0.10]), a finding confirmed with propensity score matching. Recursive partitioning analysis identified no subset of patients that derived an OS benefit from either approach over the other. OS among patients undergoing SRT was found to be superior to that of patients treated with CCRT but did not significantly differ from that of those undergoing ICRT. Because these intriguing findings require validation, SRT should remain the standard of care for patients with this disease. However, organ preservation with ICRT may be a reasonable alternative in certain patients. Cancer 2017;123:600-608. © 2016 American Cancer Society.

Therapeutic strategies for locally advanced laryngeal cancer. Part 1: Radical treatment

According to the Union for International Cancer Control (UICC)/ American Joint Committee on Cancer (AJCC), staging system for the locally advanced laryngeal cancer generally denotes stage III or IV, stage III being represented by T3 or N1 tumors and the non-metastatic stage IV including N2-N3 or T4 tumors. The main therapeutic goals are local control and survival, but also the functional organ preservation (speech, swallowing and airway patency), if possible. To achieve these objectives, the management should be established by a multidisciplinary tumor board, based on the analysis of patient-specific factors (age, performance status, comorbidities, and psychosocial support), cancer topography and staging, but also the physician expertise and the availability of rehabilitation services. Regarding the larynx preservation, there are two major therapeutic strategies: total laryngectomy (associated with adjuvant radio- and chemotherapy) and larynx preservation strategy, which includes neoadjuvant chemotherapy followed by exclusive radiotherapy or concurrent radio-chemotherapy or radio-biotherapy. Total laryngectomy can be performed by open surgery or, in order to avoid a wide surgical field and reduce the local morbidity, by transoral techniques. After laryngectomy, the recurrence can be local, at the resection site, nodal, at cervical lymph nodes, or distal, the lung being the most common site of recurrence as a distant metastasis. To improve locoregional control and survival, adjuvant treatments are proposed, including radiotherapy, chemo- and biotherapy.

Laryngeal Preservation in Glottic Cancer: A Comparison of Hospital Charges and Morbidity among Treatment Options.

When total laryngectomy is not required, organ preservation surgery or radiotherapy is considered the standard of care for primary glottic cancer. These accepted treatment options are available for early and advanced glottic cancers due to equivalent locoregional control and survival rates. However, in today's climate of accountable care, the financial burden of treatment choices continues to increase in significance. We therefore compared hospital charges and treatment-related morbidity between organ-preserving surgery and radiation with or without chemotherapy-herein, (chemo)radiation-in the primary treatment of glottic cancer. Nationwide Inpatient Sample Database was analyzed to assess clinical and financial information. Population-based analysis. Patients (N = 5499) with primary glottic cancer undergoing treatment with laryngeal preservation strategies. Patients were subdivided by ICD-9 codes into 3 treatment groups: endoscopic resection, open partial laryngectomy, and (chemo)radiation. Treatment-related outcomes, charges, and length of hospitalization were analyzed among treatment groups. When adjusting for sex, age, race, comorbidity, and primary payer, (chemo)radiotherapy was associated with increased direct charges (P < .001; coefficient, $23,658.99; 95% confidence interval [95% CI]: $10,227.15-$37,090.84) and length of hospitalization (P < .001; hazard ratio, 0.593; 95% CI: 0.502-0.702) when compared with endoscopic surgery. As compared with open surgery, endoscopic surgery was associated with reduced hospital charges (P = .012; coefficient, $11,967.01; 95% CI: $2,784.17-$21,249.85) and duration of hospitalization (P < .001; hazard ratio, 0.749; 95% CI: 0.641-0.876). This analysis suggests that increased utilization of endoscopic surgery in patients with primary glottic cancer not requiring total laryngectomy may lead to reduced financial burden and duration of hospitalization when compared with open surgery or (chemo)radiation therapy.

Combined modality therapy for thoracic and head and neck cancers: a review of updated literature based on a consensus meeting.

Combined modality therapy is a mainstay option for thoracic malignancies and head and neck cancers. The integration of different strategies is based on the multidisciplinary approach of modern clinical oncology. Radiation oncologists have to be educated, trained, and updated to provide state-of-the-art care to cancer patients and thus educational meetings are crucial. The Italian Association of Radiation Oncology Young Members Working Group (AIRO Giovani) organized its 8th national meeting, focused on combination therapy in lung, esophageal, and head and neck cancer (with a specific focus on larynx-preservation strategies for larynx/hypopharynx tumors), involving young professionals working in Italy. The meeting was addressed to young radiation oncologists, presenting state-of-the-art knowledge, based on the latest evidence in this field. We performed a review of the current literature based on the highlights of the Congress. The multimodality approach of head and neck and thoracic malignancies includes surgery, chemotherapy, and radiotherapy, but also has to take into account new information and data coming from basic and translational research and including molecular biology, genetics, and immunology. All these aspects are crucial for the treatment of non-small-cell lung cancer and esophageal, esophagogastric junction, and larynx/hypopharynx malignancies. The integration of different treatments in the clinical decision-making process to combine therapies is crucial. Combination therapy has proved to be a consolidated approach in these specific oncologic settings, highlighting the importance of multimodality management in modern clinical oncology. Dedicated meetings on specific topics are helpful to improve knowledge and skills of young professionals in radiation oncology.

Retrospective analysis of the clinical efficacy of definitive chemoradiotherapy for patients with hypopharyngeal cancer.

A retrospective analysis was performed to evaluate the clinical efficacy of definitive chemoradiotherapy including intensity-modulated radiotherapy for patients with hypopharyngeal cancer. Previously untreated 204 patients with hypopharyngeal cancer were treated with definitive chemoradiotherapy. Of note, 66-70 Gy was delivered to the primary and involved nodes and 36-54 Gy was delivered to the prophylactic lymph node using standard fractionated radiotherapy. One hundred and forty-six patients received induction chemotherapy as a larynx preservation strategy, followed by definitive radiotherapy with or without concurrent chemotherapy. Intensity-modulated radiotherapy was also performed after 2006. The median follow-up time of this cohort was 43.4 months (range; 6.9-151.0). The 3-year overall survival, progression-free survival and larynx preservation survival rates were 78.8% (95% confidence interval; 73.0-85.0), 58.4% (95% confidence interval; 51.8-65.9) and 67.5% (95% confidence interval; 61.0-74.7), respectively. Multivariate analyses identified the following significant prognostic factors: an advanced age, the T category and N category for overall survival, the T category and N category for progression-free survival and the T category for larynx preservation survival. Acute toxicities of Grade 3 or higher were observed in 47 patients (23.0%). Two patients (1.0%) had Grade 4 pharyngeal edema. Suspicious treatment-related death due to lethal pharyngeal hemorrhage occurred in 1 (0.4%) patient. The rates of Grade 2 xerostomia in patients treated with intensity-modulated radiotherapy were 28.1, 17.4 and 9.5% at 6 months, 1 and 2 years after the completion of radiotherapy, respectively. The efficacy and safety of definitive chemoradiotherapy are considered feasible with sufficient laryngeal preservation.
