e18042 Background: The median over survival (OS) of resected head and neck mucosal melanoma (HNMM) is 49.0 months. About 65% of patients experience local recurrence or distant metastasis after surgery. Therefore, adjuvant therapy is critical to improve the poor prognosis. Methods: Data regarding HNMMs with radical surgery (stage III-IVa, AJCC HNMM 8th version) between September 1, 2006 and February 28, 2020 at Peking University Cancer Hospital was collected retrospectively. Postoperative radiotherapy was usually prescribed as GTV 60-70Gy/CTV 60Gy/30f. Patients were divided into four groups by the adjuvant regimens: radiotherapy+chemotherapy (RC), chemotherapy (C), radiotherapy (R) and observation (O). Results: In total, 368 patients were enrolled, including 104 RC,114 C, 53 R, 97 O, respectively. After median follow-up of 63.9 mo (range: 0.9-146.7), the median local relapse-free survival (LRFS) was 10.1 mo (95%CI: 6.7-13.6) in the O group, as compared with 65.9 mo (95%CI: 31.7-100.1, P＜0.001) in the R group, 75.6 mo (95%CI: 50.1-101.0, P＜0.001) in the C group, and 84.6 mo (95%CI: 48.5-120.8, P＜0.001) in the RC group. The median distant metastasis-free survival (DMFS) was 13.7 mo (95%CI: 8.0-19.5) in the O group, 15.3 mo (95%CI: 8.7-21.9, P = 0.898) in the R group, as compared with 25.7 mo (95%CI: 14.6-36.8, P = 0.001) in the C group, 49.3 mo (95%CI: 32.6-66.0, P＜0.001) in the RC group. Estimated OS was 36.4 mo (95%CI: 24.0-48.8) in the O group, as compared with 30.8 mo (95%CI: 23.0-38.6, P = 0.733) in the R group, 40.8 mo (95%CI: 34.8-46.8, P = 0.289) in the C group, 58.2 mp (95%CI: 36.4-79.9, P = 0.002) in the RC group. Primary location, age, gender, UICC staging and adjuvant regimens were included for multivariate Cox analysis. With regard to OS, UICC stage and RC were the prognostic factors. With regard to DMFS, UICC stage, RC and C were the prognostic factors. With regard to LRFS, UICC stage, RC, R, C were the prognostic factors. Conclusions: It is the largest study on the role of adjuvant radiotherapy and chemotherapy on HNMM till now. The results demonstrate that postoperative radiotherapy improves LRFS but has no impact on DMFS, while adjuvant radiotherapy plus chemotherapy prolongs OS. It further validates the clinical practice of UICC stage of HNMM, which might shed lights on the study of the whole mucosal melanoma.

Abstract Objectives The study aims to analyze the clinical characteristics of head and neck mucosal melanoma (MMHN) and the effects of multiple treatment modalities on distant metastasis, recurrence and survival rates to provide a reference for the individualized treatment of MMHN. Methods We retrospectively reviewed 262 patients with stage III–IVb MMHN treated from March 1986 to November 2018 at our cancer center. Results The median follow-up time was 34.0 months (range 1–262 months). The 5-year overall survival (OS), distant metastasis-free survival (DMFS) and disease-free survival (DFS) probabilities were 37.7%, 30.2%, and 20.3%, respectively. The 5-year OS rates for patients with stage III, stage IVA, and stage IVB MMHN were 67.0%, 24.1% and 8.3%, respectively (P < 0.001). A total of 246 (93.9%) patients received surgery, 149 (56.9%) patients received chemotherapy, and 69 (26.3%) patients received immunologic/targeted therapy. A total of 106 (40.5%) patients were treated with radiotherapy: 9 were treated with preoperative radiotherapy, 93 were treated with postoperative radiotherapy, and 4 were treated with radiotherapy alone. In the multivariate Cox regression analysis, primary tumor site, T stage, and immunologic/targeted therapy were independent factors for OS (all P < 0.05). Irradiation technique, T stage, and N stage were independent prognostic factors for DMFS (all P < 0.05). T stage, N stage, and surgery were independent prognostic factors for DFS (all P < 0.05). Distant metastasis was observed in 107 of 262 patients (40.8%), followed by local [74 (28.2%)] and regional [52 (19.8%)] recurrence. Conclusions The main reason for treatment failure in MMHN is distant metastasis. Immunologic/targeted therapy and surgery are recommended to improve the survival of MMHN. The American Joint Committee on Cancer (AJCC) 8th edition staging system for MMHN does stage this disease effectively.

Abstract Background Primary mucosal melanoma of the head and neck (MMHN) is a rare, aggressive tumor of neural-crest origin. Despite universal progress in cancer care, the prognosis of MMHN continues to remain dismal. Aims To analyze and report the outcomes of primary head and neck mucosal melanomas treated at Tata Memorial Hospital. Methods Retrospective chart review of all patients with a diagnosis of nonocular MMHN presenting to the institute between 1995 to 2003. Locoregional control and disease-free survival were used as outcome measures. Results 42 patients presenting within the study period with nonocular MMHN (oral-55%, sinonasal-40%, and pharyngeal-5%) at a median age of 53 years constituted the demographic cohort. 11 (26%) patients not amenable to any active anticancer treatment were treated with best supportive care alone and excluded from outcome analysis. 26 patients underwent surgery with complete resection of tumor. Seven (27%) also received adjuvant radiotherapy due to the adverse histopathologic features. Two patients were treated with radical radiotherapy due to unresectability, two patients received palliative chemotherapy, while one patient was treated with definitive chemoradiotherapy. With a mean follow-up of 11 months (range 1-58 months), the 3-year locoregional control and disease-free survival was 41% and 12% respectively. Age, sex, site of primary, tumor stage, surgical resection, margin status, depth of infiltration, and adjuvant radiotherapy did not affect outcome significantly. Conclusion Primary mucosal melanoma of the head and neck is a rare, but, aggressive tumor with a dismal prognosis. Surgical resection with clear margins offers the best chance of cure for early localized disease. The high incidence of locoregional as well as distant failures after surgical resection supports the use of adjuvant therapy. Deeper insights into the pathobiology of disease can help develop more specific and effective treatment strategies to improve long-term outcomes.

Abstract Background and purpose Concurrent chemoradiotherapy is the established treatment for locally advanced nasopharyngeal carcinoma (NPC). However, there is no evidence supporting routine adjuvant chemotherapy. We aimed to demonstrate the effect of adjuvant chemotherapy on survival and distant metastasis in high-risk N3 NPC patients. Materials and methods We linked the Taiwan Cancer Registry and Cause of Death database to obtain data. Clinical N3 NPC patients were divided as those receiving definitive concurrent chemoradiotherapy (CCRT) with adjuvant 5-fluorouracil and platinum (PF) chemotherapy and those receiving no chemotherapy after CCRT. Patients receiving neoadjuvant chemotherapy were excluded. We compared overall survival, disease-free survival, local control, and distant metastasis in both groups using Cox proportional hazards regression analysis. Results We included 431 patients (152 and 279 patients in the adjuvant PF and observation groups, respectively). Median follow-up was 4.3 years. The 5-year overall survival were 69.1% and 57.4% in the adjuvant PF chemotherapy and observation groups, respectively (p = 0.02). Adjuvant PF chemotherapy was associated with a lower risk of death (hazard ratio [HR] = 0.61, 95% confidence interval [CI]: 0.43–0.84; p = 0.003), even after adjusting for baseline prognostic factors (HR = 0.61, 95% CI: 0.43–0.86; p = 0.005). Distant metastasis-free survival at 12 months was higher in the adjuvant PF chemotherapy group than in the observation group (98% vs 84.8%; p < 0.001). After adjusting for baseline prognostic factors, adjuvant PF chemotherapy was associated with freedom from distant metastasis (HR = 0.11, 95% CI: 0.02–0.46; p = 0.003). Conclusion Prospective evaluation of adjuvant PF chemotherapy in N3 NPC patients treated with definitive CCRT is warranted because adjuvant PF chemotherapy was associated with improved overall survival and decreased risk of distant metastasis.

Objectives. To investigate the prognostic factors and treatment outcomes of primary parotid carcinoma treated with surgery and postoperative radiotherapy (PORT).Methods. We reviewed retrospectively 57 patients with primary parotid carcinoma who were treated with surgery and PORT between 2005 and 2014. Superficial parotidectomy was performed in 19 patients, total parotidectomy in 10 patients, and total parotidectomy with lymph node dissection in 28 patients PORT on the tumor bed was performed in 41 patients, while PORT on tumor bed and ipsilateral cervical lymph nodes was performed in 16 patients.Results. With a median follow-up of 66 months, the 5-year overall survival, disease-free survival, locoregional control, and distant control rates were 77.0%, 60.2%, 77.6%, and 72.8%, respectively. The 5-year overall survival by stage was 100%, 100%, 80.0%, and 46.4% in stage I, II, III, and IV, respectively. Recurrences at primary lesions were found in seven patients, while at cervical nodes in six patients. Distant recurrences were developed in 12 patients. No patient with the low and intermediate histologic grade developed distant failure. As prognostic factors, the histologic grade for overall survival (P=0.005), pathological T-stage (P=0.009) and differentiation grade (P=0.009) for disease-free survival, pathological T-stage for locoregional control (P=0.007), and lympho-vascular invasion (P=0.023) for distant recurrence were significant on multivariate analysis.Conclusion. This study revealed that differentiation grade, histologic grade, pathological T-stage, and lympho-vascular invasion were significant independent prognostic factors on clinical outcomes.

ObjectiveTo analyze the prognostic factors and treatment outcomes in endometrial cancer patients with paraaortic lymph node metastasis.MethodsData from four centers were collected retrospectively for 92 patients with endometrial cancer treated with combined radiotherapy and chemotherapy or adjuvant radiotherapy alone postoperatively, delivered by either the sandwich or sequential method. Prognostic factors affecting overall survival and progression-free survival were analyzed.ResultsThe 5-year overall survival and progression-free survival rates were 35 % and 33 %, respectively, after a median follow-up time of 33 months. The 5-year overall survival and progression-free survival rates were significantly higher in patients receiving radiotherapy and chemotherapy postoperatively compared with patients treated with adjuvant radiotherapy alone (P < 0.001 and P < 0.001, respectively). In a subgroup analysis of patients treated with adjuvant combined chemotherapy and radiotherapy, the 5-year overall survival and progression-free survival rates were significantly higher in patients receiving chemotherapy and radiotherapy via the sandwich method compared with patients treated with sequential chemotherapy and radiotherapy (P = 0.02 and P = 0.03, respectively). In the univariate analysis, in addition to treatment strategy, pathology, depth of myometrial invasion, and tumor grade were significant prognostic factors for both overall survival and progression-free survival. In the multivariate analysis, grade III disease, myometrial invasion greater than or equal to 50%, and adjuvant radiotherapy alone were negative predictors for both overall survival and progression-free survival.ConclusionWe demonstrated that adjuvant combined treatment including radiotherapyand chemotherapy significantly increases overall survival and progression-free survival rates compared with postoperative pelvic and paraaortic radiotherapy.

AbstractAims:To investigate prognostic factors for survival and locoregional control in patients with stage I–IVA hypopharyngeal cancer treated with laryngeal preservation radiotherapy.Methods:This study was a retrospective analysis of 108 patients with stage I–IVA squamous cell carcinoma of the hypopharynx, treated with laryngeal preservation radiotherapy. Actuarial survival, disease-specific survival and local relapse-free survival were calculated, and multivariate analyses were performed using Cox's proportional hazards model.Results:After a median follow-up duration of 39 months, the five-year local relapse-free survival rate was 35 per cent for all patients, 66 per cent for those with stage I–II disease, 46 per cent for those with stage III disease and 20 per cent for those with stage IVA disease (p = 0.004). Multivariate analyses showed that tumour and node stages were independent prognostic factors.Conclusions:Patients with stage I–II disease were suitable for laryngeal preservation radiotherapy. For most patients with stage III–IVA disease, other than those who were T1 N1 or T2 N1, the treatment results were poor.

Atypical Meningiomas

Object The role of postoperative radiation therapy after surgery for atypical meningiomas remains controversial. In this retrospective cohort study, the authors examine the recurrence rates for atypical meningiomas after resection (with or without adjuvant radiotherapy) and identify which factors were associated with recurrence. Methods Of 90 patients with atypical meningiomas who underwent surgery between 1999 and 2009, 71 (79%) underwent gross-total resection (GTR) and 19 (21%) underwent subtotal resection (STR); 31 patients received adjuvant radiotherapy. All tumors were pathology-confirmed WHO Grade II atypical meningiomas. Univariate and multivariate analyses were performed to identify factors associated with recurrence-free survival. Results Among 90 patients, 17 developed tumor recurrence (81% recurrence-free survival at 5 years). In the overall group, adjuvant radiotherapy reduced the recurrence rate to 9% from 19% at 5 years (p = 0.048). After STR, adjuvant radiotherapy significantly reduced recurrence from 91% to 20% (p = 0.0016). However, after GTR, adjuvant radiotherapy did not significantly reduce the recurrence rate (16.7% without radiation therapy vs 11.8% with radiation therapy) (p = 1.00). Five factors independently predictive of tumor recurrence included mitotic index, sheeting, necrosis, nonuse of radiation therapy, and STR. Further recursive partitioning analysis showed significant increases in risk for patients older than 55 years with mitoses and sheeting. Conclusions Adjuvant radiotherapy was effective at lowering recurrence rates in patients after STR but delivered no significant improvement in patients after GTR. Given that rates after GTR were similar with or without adjuvant radiotherapy, close observation without postoperative radiation therapy may be a viable option for these patients. Patients older than 55 years and those with mitoses noted during pathological examination had a significant risk of recurrence after GTR; for these patients, postoperative radiotherapy is recommended.

AbstractBackgroundThe beneficial effect of postoperative radiotherapy (PORT) on completely resected pathological IIIA-N2 (pIIIA-N2) non-small cell lung cancer (NSCLC) has been a subject of interest with controversy. The aim of the study was to distinguish the clinical efficacy of PORT on lung adenocarcinoma (LADC) and lung squamous cell carcinoma (LSCC) among pIIIA-N2 NSCLC.Patients and methodsBetween October 2010 and September 2016, 288 consecutive patients with completely resected pIIIA-N2 NSCLC at Beijing Chest Hospital were retrospectively analyzed, which consisted of 194 cases of LADC and 85 cases of LSCC. There were 42 (21.6%) patients treated with PORT in LADC cases and 19 (22.3%) patients treated with PORT in LSCC cases. The 5-year overall survival (OS), loco-regional recurrence-free survival (LRFS), distant metastasis-free survival (DMFS) were calculated using the Kaplan-Meier method. The prognostic factors were determined using Cox’s regression model.ResultsAmong 194 cases of LADC, the 1-, 3-, and 5-year OS in the PORT group were 95.2%, 61.9% and 40.0%, respectively, while in the non-PORT group were 90.1%, 63.3% and 45.0% (p = 0.948). The use of postoperative chemotherapy (POCT) and smoking index ≥ 400 were both prognostic factors of 5-year rates of OS, LRFS and DMFS. On the other hand, among 85 cases of LSCC, the 1-, 3-, and 5-year OS in the PORT group were 94.7%, 63.2% and 63.2%, respectively, whereas in the non-PORT group were 86.4%, 48.5% and 37.1% (p = 0.026). In this group, only the use of PORT was a favorable prognostic factor for 5-year OS, LRFS and DMFS.ConclusionsDue to clinicopathological differences among completely resected pIIIA-N2 NSCLC, PORT may not be suitable to all patients. Our study distinguishes pIIIA-N2 LSCC from LADC by their positive responses to PORT.
