Purpose To investigate the role of quantitative pre-treatment dual-energy computed tomography (DECT) for prediction of loco-regional recurrence (LRR) in patients with larynx/hypopharynx squamous cell cancer (L/H SCC). Methods Patients with L/H SCC treated with curative intent loco-regional radiotherapy and that underwent treatment planning with contrast-enhanced DECT of the neck were included. Primary and nodal gross tumor volumes (GTVp and GTVn) were contoured and transferred into a Matlab® workspace. Using a two-material decomposition, GTV iodine concentration (IC) maps were obtained. Quantitative histogram statistics (maximum, mean, standard deviation, kurtosis and skewness) were retrieved from the IC maps. Cox regression analysis was conducted to determine potential predictive factors of LRR. Results Twenty-five patients, including 20 supraglottic and 5 pyriform sinus tumors were analysed. Stage I, II, III, IVa and IVb constituted 4% (1 patient), 24%, 36%, 28% and 8% of patients, respectively; 44% had concurrent chemo-radiotherapy and 28% had neodjuvant chemotherapy. Median follow-up was 21 months. Locoregional control at 1 and 2 years were 75% and 69%, respectively. For the entire cohort, GTVn volume (HR 1.177 [1.001-1.392], p = 0.05), voxel-based maximum IC of GTVp (HR 1.099 [95% CI: 1.001–1.209], p = 0.05) and IC standard deviation of GTVn (HR 9.300 [95% CI: 1.113–77.725] p = 0.04) were predictive of LRR. On subgroup analysis of patients treated with upfront radiotherapy +/- chemotherapy, both voxel-based maximum IC of GTVp (HR 1.127 [95% CI: 1.010–1.258], p = 0.05) and IC kurtosis of GTVp (HR 1.088 [95% CI: 1.014–1.166], p = 0.02) were predictive of LRR. Conclusion This exploratory study suggests that pre-radiotherapy DECT-derived IC quantitative analysis of tumoral volume may help predict LRR in L/H SCC.

Objectives The aims of this study were to assess oncologic and functional outcome in primary total laryngectomy or pharyngolaryngectomy (TL/TL/TPL) for laryngeal or hypopharyngeal cancer with extra-laryngeal extension (T4) and to determine the predictive factors of these results. Material and methods A retrospective analysis was performed on the computerized medical records of all patients undergoing primary TL/TPL for T4 larynx or hypopharynx squamous cell carcinoma between 2000 and 2014 at our institution. Predictive factors of oncologic and functional outcome were investigated on univariate and multivariate analysis. Results Sixty-three patients (58 men, 5 women; mean age, 68.8 ± 9.7 years) were included. Overall and disease-specific survivals were 69% and 80% at 3 years, and 56% and 69% at 5 years, respectively. On multivariate analysis, gender (female, P P = 0.006) and vascular embolism ( P = 0.006) had significant pejorative impact on overall survival. Six months after end of treatment, 90% of patients had recovered independent oral feeding and 83% of those with tracheoesophageal voice prostheses had recovered an intelligible voice. Conclusion Primary TL/TPL remains the gold standard treatment for T4 larynx or hypopharynx cancer. It provides satisfactory oncologic and functional outcomes.

This article reviews the concept of selectivity in peritumoral microscopic disease to be included in the Clinical Target Volume (CTV) for elective treatment for larynx and hypopharynx squamous cell carcinoma (50 Gy or 54-60 Gy for SIB-IMRT), using the local tumoral spread. The objective of the present article is to present the different delineations of the target volumes, required for an appropriate application of 3-DCRT and IMRT (supraglottic larynx, vocal cord, subglottic larynx, pyriform sinus, lateral and posterior pharyngeal wall and postcricoid pharynx). These propositions are for the delineation of microscopic peritumoral target volumes when external beam irradiation is required. CTVs are illustrated on CT sections.

Longtemps la chirurgie radicale et la radiotherapie ont ete les deux seules options du traitement des tumeurs avancees du pharyngo-larynx. Les progres de la chirurgie partielle, endoscopique ou non, et ceux de la radiotherapie exclusive ont permis d’eviter dans un certain nombre de cas la mutilation laryngee. La chimiotherapie a acquis une place de choix dans ces strategies de preservation de la fonction laryngee. Plusieurs sequences sont realisables: chimiotherapie et radiotherapie sequentielles, chimiotherapie et radiotherapie concomitantes ou, plus recemment, radio-chimiotherapie sequentielle. L’apparition de nouveaux agents cyto-toxiques et des therapeutiques ciblees doit egalement etre prise en compte. Plus que jamais une approche pluridisciplinaire s’impose pour adapter le traitement le plus approprie et pour determiner les futures etudes cliniques.

Resume Objectifs. – Le carcinome epidermoide hypopharynge est associe a l’un des pronostics les plus defavorables des cancers de la sphere ORL. L’objectif de ce travail etait d’analyser ses modalites therapeutiques a l’institut Salah-Azaiz (Tunis) et de comparer leurs resultats. Patients et methodes. – Cette etude retrospective porte sur 271 carcinomes epidermoides de l’hypopharynx, colliges au service de chirurgie carcinologique cervicofaciale et ORL de l’institut Salah-Azaiz sur une periode de 25 ans (1977 a 2002). L’âge moyen des patients etait de 56 ans ; le sex-ratio etait en moyenne de 1,2 (homme/femme). L’indication d’un traitement a visee curative a ete initialement retenue pour 149 (55 %) patients, qui ont ete les seuls retenus pour l’analyse des resultats. Resultats. – Nous avons retenu l’indication d’un protocole incluant chirurgie et radiotherapie postoperatoire pour 26,2 % des patients. Le taux de mortalite postoperatoire etait de 5,1 % ; le taux de morbidite operatoire etait de 46,2 %. Pour 13,5 % des patients, la radiotherapie postoperatoire a ete definitivement interrompue en raison d’une alteration progressive de l’etat general en cours de traitement. Nous avons pose l’indication d’une radiotherapie exclusive pour 59,7 % des patients. L’âge moyen etait de 56 ans et le sex-ratio de 1,2. La telecobaltotherapie externe etait delivree en fractionnement et etalement classiques. La radiotherapie a du etre definitivement interrompue en cours de realisation dans 32,6 % des cas devant une aggravation de l’etat general ; le taux de morbidite liee a la radiotherapie etait de 33,3 %. Un protocole de conservation d’organe avec chimiotherapie neoadjuvante a ete propose a 21 patients (14,1 %). L’âge moyen etait de 53 ans (28 a 65 ans) et le sex-ratio (homme/femme) de 0,5. Le taux de survie globale etait de 25,5 % a un an, 18,1 % a deux ans, 11,4 % a trois ans et 7,4 % a cinq ans. Tous les patients a qui a ete proposee une chimiotherapie sont decedes en cours de traitement. Les taux de survie a deux et a cinq ans des patients traites par chirurgie et irradiation et par irradiation exclusive etaient respectivement de 21,5 et 12 %, et 18,3 et 10 %. La difference de survie entre ces deux populations therapeutiques n’etait pas significative (p = 0,08). Conclusion. – Tandis que la chimiotherapie neoadjuvante apparait dans notre serie comme grevee d’une lourde mortalite, l’association chirurgie–radiotherapie et la radiotherapie exclusive semblent d’une efficacite similaire dans le traitement du carcinome hypopharynge.

Resume Objectifs. – Le carcinome epidermoide hypopharynge est associe a un pronostic defavorable, auquel l’envahissement ganglionnaire cervical et les metastases a distance contribuent. L’objectif de cette etude etait d’evaluer la frequence, le mode et la signification pronostique de ses metastases regionales et a distance. Patients et methodes. – Les auteurs rapportent une etude retrospective portant sur 271 carcinomes epidermoides de l’hypopharynx, colliges au service de chirurgie carcinologique cervicofaciale et ORL de l’institut Salah-Azaiz de 1977 a 2002. La frequence et les caracteres histocliniques des metastases regionales et a distance ont ete evalues, ainsi que leur signification pronostique chez les 155 patients traites dans un but curatif. Resultats. – 39,1 % des cancers etaient classes N0, 24,4 % N1, 10,7 % N2 et 25,8 % N3 (UICC 2002). Les adenopathies cervicales etaient significativement plus frequentes pour les tumeurs classees T3T4 que pour les T1T2 (soit, pour les tumeurs des sinus piriformes, celles de la region retrocricoarytenoidienne, celles de la paroi posterieure et celles etendues de l’hypopharynx, respectivement : p = 0,001, p = 0,007, p = 0,047, et p = 0,0005). Trente-deux patients ont beneficie d’un evidement ganglionnaire cervical. Parmi ceux dont le cancer a ete classe N0, il a ete trouve 46,9 % d’atteintes ganglionnaire (N+) ; les frequences de la rupture capsulaire n’etaient pas significativement differentes pour les cancers classes N0N1 et pour ceux qui etaient N2N3 ( p = 0,11). Les taux de survie globale a deux et a cinq ans etaient respectivement de 32,5 et 20,5 % pour les patients dont la tumeur etait classee N0, 10,9 et 0 % si elle etait N3. Les differences de taux de survie a deux et a cinq ans entre les patients dont la tumeur etait N0N1 et ceux dont elle etait N2N3 etaient significatives ( p = 0,04). Un echec ganglionnaire cervical a ete constate chez 18,5 % des patients. Le site tumoral n’influencait pas significativement le taux d’echec ganglionnaire ( p = 0,98), non plus que le statut clinique N ( p = 0,34). La rupture capsulaire etait un facteur significatif de prediction d’un echec ganglionnaire ( p = 0,007). Le taux de dissemination metastatique a distance etait de 2,6 % au premier examen, et secondairement de 12,3 %. Les metastases a distance etaient significativement plus frequentes chez les patients dont le cancer etait initialement classe N2N3 que chez ceux dont il etait N0N1 ( p = 0,03), ainsi qu’en cas de rupture capsulaire ( p = 0,0009). Conclusion. – Le carcinome epidermoide de l’hypopharynx est caracterise par une grande lymphophilie, qui est liee a l’extension locale, et par la grande frequence des metastases ganglionnaires occultes. Le statut clinique ganglionnaire ne semble pas influencer la probabilite de survie ; cependant, la rupture capsulaire constitue un facteur de prediction d’un echec ganglionnaire cervical et de metastases a distance. Les metastases a distance sont frequentes, particulierement en cas de tumeur etendue aux plans local ou regional, et la probabilite de survie est dans ce cas nulle a un an.
