Primary laryngeal carcinosarcoma is a rare type of malignancies, and the standard therapeutic protocol for its treatment has yet to be established. This retrospective study analyzed the clinical and pathological characteristics, risk factors, treatment options, and prognosis of 13 patients with primary laryngeal carcinosarcomas. This case series included 11 males and 2 females with an age range from 32 to 78 years at diagnosis. The initial clinical symptoms included hoarseness, dyspnea, and foreign body sensation in the throat. The primary tumor sites were at the glottis, supraglottis, and larynx. All these patients were active or passive smokers, and more than half of them were alcohol addictive. The surgical treatment for laryngeal carcinosarcomas included CO2 laser surgery in seven cases, partial laryngectomy and neck dissection in three cases, and total laryngectomy and neck dissection in three cases. Among them, seven cases received postoperative radiotherapy. After follow-up with a mean of 31.15-month, four cases died. Primary laryngeal carcinosarcoma is a rare but more aggressive malignancy. Contralateral lymph node metastasis can occur at the early stage of this disease. A treatment combining surgery and postoperative radiotherapy is strongly recommended.

Background The prognostic factors and survival difference between inverted papilloma (IP)-associated sinonasal squamous cell carcinoma (SCC) and de novo SCC are unclear. Objective This study aimed to compare the clinical features and oncologic outcomes in patients with IP-associated SCC and de novo SCC; and additionally, to analyze the prognostic factors of the two types of SCCs. Methods Data from 173 SCC patients treated for IP-associated SCC (n = 89) and de novo SCC (n = 84), were reviewed retrospectively for demographic features, tumor characteristics, treatment modality, and clinical outcomes. 5-year overall survival (OS) and disease free survival (DFS) was analyzed using the Kaplan-Meier method, and Cox proportional hazards model was used to analyze factors influencing prognosis. Results A higher proportion of IP-associated SCC occurred in frontal and sphenoid sinus compared to de novo SCC. The two groups demonstrated similar 5-year OS and DFS (5-year OS: 63.3% and 55.4%, DFS: 45.4% and 50.1%, respectively). The metachronous tumor had a relatively better prognosis outcome than synchronous tumor and de novo SCC (5-year OS: 73.1%, 54.5% and 55.4%, respectively). Both groups showed similar loco-regional recurrence rates ( p > 0.05); however, de novo SCC tumors demonstrated an increased incidence of distant metastasis. Multivariate analysis indicated that age >70 years, advanced tumor stage and surgical margin were independent predictive factors for the risk of mortality (HR 2.047, 1.581 and 1.931, respectively). Conclusion IP-associated SCCs have an aggressive loco-regional tendency, whereas de novo SCCs have a higher aggressive distant metastatic propensity. Age, tumor stage and surgical positive margin are key factors for poor prognosis and should be routinely taken into consideration during treatment planning and subsequent surveillance.

Backgroud: Induction chemotherapy, as a larynx preservation treatment, has been available for over 20 years. We conducted a retrospective study to evaluate the efficacy of this protocol with taxene, cisplatin and 5-fluorouracil in Chinese patients with hypopharyngeal cancer that chose preservation strategy.170 patients with locally advanced hypopharyngeal cancer were assigned to receive induction chemotherapy. 107 patients (63%) with complete response or partial response received larynx preservation treatment and 63 non-responders (37%) received radical surgery.Median survival time was 30 months (range: 3-59 months). 63 patients (37%) had local-regional failure and 15 (9%) had distant metastasis. Three-year LFS was 27.8% (95% CI: 23.6-32.0%). The estimated three-year overall survival rate was 44.5% (95% CI: 39.5-49.5%). There was no significant difference in the three-year survival rate between responders (44.8%) and non-responders (43.9%) (p = .237), however patients with a partial response had a significant decrease in survival (32.2%) (p .001).In patients with hypopharyngeal cancer, ICT with TPF regimen followed by RT, as a larynx preservation treatment, may be suitable for complete responders, but not partial responders.

Purpose This study was to investigate clinicopathologic characteristics and prognostic factors in adenoid cystic carcinoma of head and neck minor salivary glands. Materials and methods We conducted a retrospective review of 130 patients with adenoid cystic carcinoma of head and neck minor salivary glands that were evaluated between 2000 and 2013 in Beijng Tongren Hospital. Results Five-year overall survival and disease-free survival rates were 80.8% and 55.6%. Local recurrence rate was 40%, regional recurrence 3.8%, and distant metastasis was 28.5%. On univariate analysis, solid histological subtype, perineural invasion, positive surgical margins and advanced stages were found to be poor prognostic indicators. On multivariate analysis, solid histological subtype and positive surgical margins were significant prognostic factors of worse overall survival. Conclusions Solid histological subtype and positive surgical margins were the most important predictors of poor outcome in adenoid cystic carcinoma of minor salivary glands. Surgery with postoperative radiation were recommended treatment and offered durable local control.

To explore the feasibility and effect of CO2 laser surgery for early glottic carcinoma with anterior commissure involvement.Twenty-seven patients with T1b glottic squamous cell carcinoma who underwent transoral CO2 laser surgery as the primary modality of treatment from January 2008 to August 2013 were reviewed. All patients were males and the age ranged from 46 to 81 years old. The patients did not receive any other treatments. Preoperative enhanced CT scan was performed to assess the status of the tumors and the lamina of thyroid cartilage. All the patients without the lamina of thyroid cartilage involved underwent transoral CO2 laser surgery.Among 27 cases, aside from 1 patient converted to open operation due to inadequate exposure, 26 patients were successfully implemented operation. All the patients were followed-up for 12 to 60 months (median 26 months) and no recurrence. Granulation occurred four to six weeks after operation in all patients. Among them, granulation disappeared automatically three to six months in 22 patients and was resected with local anesthesia in other 4 patients, which the pathological results were inflammatory lesion. All patients did not undergo tracheotomy and nasogastric feeding, with an average stay of three days in hospital after surgery, and had different degree of vocal cord adhesion 6 months later.Transoral CO2 laser surgery is an ideal procedure for early glottic carcinoma with anterior commissure involvement. Better preoperative evaluation, endoscopic technique and satisfied exposure are keys to the success of operation.
