The Prognostic Significance of IGF-1R and the Predictive Risk Value of Circulating IGF-1 in Tunisian Patients with Laryngeal Carcinoma.

The aim was to evaluate the clinical impact of IGF-1/IGF-1R in Tunisian laryngeal carcinoma. A high IGF-1R immunohistochemical expression was found in our series (81.43%). A tendency toward an association between IGF-1R expression and lymph node metastasis was found (p = 0.068). Patients with positive IGF-1R expression showed a short disease free survival (p = 0.053) and a high recurrence rate. Furthermore, circulating IGF-1 levels sera, detected by ELISA, were higher among patients compared to controls (p < 0.001). IGF-1R might have a prognostic significance and could be a factor of tumor recurrence. However, high levels of IGF-1 increase the risk of developing of LSCC disease.

Lip reconstruction after cancer resection : clinical study of 70 cases.

BACKGROUND: By virtue of their multiple functions, lips are essential organs. Thus, lip cancers represent a distinct entity in head and neck surgery. Their treatment is fundamentally surgical. We aimed, in this study, to define modalities of repairing techniques of lip defects after surgical resection and post-operative complications. METHODS: We conducted a 4 years retrospective descriptive study including 70 adult patients admitted with lip cancers. RESULTS: Suture, local and regional flaps were the performed techniques for repairing defects (respectively n=28, 35 and 7). The most common postoperative complications were wound dehiscence (n=4), and surgical site necrosis (n=2) and infection (9 patients). Functional sequelae were dominated by microstomia (n=26), (food leakage) (n=9) and gingival exposure (n=11). Aesthetic results were good, fair or poor respectively in 54.3%; 32.9% and 12.8% of patients. CONCLUSION: Lip cancers surgery is relatively well-codified. However, it may be difficult to choose the best repairing technique, especially in case of large lip defect considering functional and aesthetic prejudices.

Risk factor of pharyngocutaneous fistula.

INTRODUCTION: Pharyngocutaneous fistula is the most frequent complication of primary and secondary laryngectomy and pharyngolaryngectomy. It has an important impact on the patient, his entourage and the healthcare team. The risk factors for pharyngostoma are multiple and its treatment is not codified. AIM: To identify the various factors that may predispose to this complication and to describe the different therapeutic means to control it. METHODS: This retrospective study examined 68 cases of laryngeal cancer treated by total laryngectomy or pharyngolaryngectomy at Salah Azaїez's head and neck oncologic surgery department between 2015 and 2017. RESULTS: Most of our patients were male (97%) who were major consumer of tobacco and alcohol. The most common stage were T4aN0M0 (34%) and T4aN1M0 (22%). Regarding treatment, we found that 73.5% of patients were operated on by total laryngectomy, 17.7% of patients were operated on by total pharyngolaryngectomy and 8.8% of patients were operated on by square laryngectomy. Pharyngostoma was diagnosed in 20.5% of cases within an average of 15 days. Among the risk factors studied, those that were statistically correlated with the occurrence of CPF in univariate studies were pre-laryngeal infiltration (p = 0.006), postoperative CRP level (p= 0.017), extension to piriform recess (p = 0.009), TNM stage (p=0.039), an associated thyroid surgery (p = 0.020) and pharyngeal closure under tension (p=0.000). In multivariate studies, five of the risk factors identified in the univariate analysis were found. This testifies to their major role as a risk factor for pharyngostoma. These factors were pre-laryngeal infiltration (p=0.001), postoperative CRP level (p=0.000), piriform recess involvement (p=0.004) Associated thyroid surgery (p=0.012) and pharyngeal closure under tension (p = 0.000). CONCLUSION: By identifying predictive factors for pharyngostoma, we can identify patients in which this complication may occur and manage the medical care means to prevent it more efficiently.

Bilateral external laryngocele: a case report.

Laryngocele is a rare benign lesion of the larynx caused by an abnormal dilatation of the laryngeal saccule. We report the case of a 78-year-old man presenting bilateral cervical painless soft mass. Bilateral external laryngocele diagnosis was confirmed by CT scan and the patient underwent a surgical resection.
