Objective The aim of the present study was to evaluate the prognostic value of radiologic extranodal extension (rENE) in patients with nasopharyngeal cancer. Study Design Retrospective review. Setting Tertiary university hospital. Methods We identified patients with nasopharyngeal cancer and lymph node metastasis who underwent pretreatment neck computed tomography or magnetic resonance imaging and evaluated rENE from the involved lymph node. Univariate Kaplan-Meier and multivariate Cox regression analyses were used to compare rENE+ and rENE– groups for local regional relapse–free survival, distant metastasis–free survival, and overall survival. Results Of 61 cases, 24 (39.3%) were rENE+ and 37 (60.7%) were rENE–. The median follow-up was 65.5 months. The 5-year distant metastasis–free survival and overall survival rates were lower in the rENE+ group than the rENE– group (70.8% vs 89.2%, P = .016; 66.7% vs 89.2%, P = .01, respectively). Differences in locoregional control between the groups were not significant ( P = .18). The 5-year rates for local regional relapse–free survival were 87.5% for rENE+ and 91.9% for rENE–. In multivariate analysis, the presence of rENE was a significant independent adverse prognostic factor for distant metastasis–free survival and overall survival. Conclusions We showed that rENE is an independent prognostic factor for poor distant control and survival in patients with nasopharyngeal cancer.

ObjectiveThe association between the prognosis of thymoma and MG remains controversial. Differences in clinical characteristics and treatments between patients with and without MG may affect the findings of those studies. We designed this propensity score matching trial to investigate whether MG is an independent prognostic predictor in thymoma.MethodsPatients with pathologically diagnosed thymoma and MG were enrolled in the MG group. Moreover, the propensity score matching method was used to select patients who were diagnosed with thymoma without MG from the database of two participating centers. Matched factors included sex, age, Masaoka stage, pathological subtypes, and treatments. Matched patients were enrolled in the non-MG group. Chi-squared test was used to compare the characteristics of the two groups. Overall survival, local-regional relapse-free survival, distant metastasis-free survival, progression-free survival, and cancer-specific survival were calculated from the diagnosis of thymoma using the Kaplan–Meier method.ResultsBetween April 1992 and October 2018, 235 patients each were enrolled in the MG and non-MG groups (1:1 ratio). The median ages of patients in the MG and non-MG groups were 46 years old. The World Health Organization pathological subtypes were well balanced between the two groups (B2 + B3: MG vs. non-MG group, 63.0 vs. 63.4%, p = 0.924). Most patients in both groups had Masaoka stages I–III (MG vs. non-MG group, 90.2 vs. 91.5%, p = 0.631). R0 resections were performed in 86.8 and 90.2% of the MG and non-MG groups, respectively (p = 0.247). The median follow-up time of the two groups was 70.00 months (MG vs. non-MG group, 73.63 months vs. 68.00 months). Five-year overall survivals were 92.5 and 90.3%, 8-year overall survivals were 84.2 and 84.2%, and 10-year overall survivals were 80.2 and 81.4% (p = 0.632) in the MG and non-MG groups, respectively. No differences were found in the progression-free survival, distant metastasis-free survival, and local-regional relapse-free survival between the two groups.ConclusionMG is not an independent or direct prognostic factor of thymoma, although it might be helpful in diagnosis thymoma at an early stage, leading indirectly to better prognosis.

Background.To evaluate the outcomes of nasopharyngeal carcinoma (NPC) patients treated with helical tomotherapy (HT).Methods.Between September 2007 and August 2012, 190 newly diagnosed NPC patients were treated with HT. Thirty-one patients were treated with radiation therapy as single modality, 129 with additional cisplatin-based chemotherapy with or without anti-EGFR monoclonal antibody therapy, and 30 with concurrent anti-EGFR monoclonal antibody therapy.Results.Acute radiation related side effects were mainly grade 1 or 2. Grade 3 and greater toxicities were rarely noted. The median followup was 32 (3–38) months. The local relapse-free survival (LRFS), nodal relapse-free survival (NRFS), distant metastasis-free survival (DMFS), and overall survival (OS) were 96.1%, 98.2%, 92.0%, and 86.3%, respectively, at 3 years. Cox multivariate regression analysis showed that age and T stage were independent predictors for 3-year OS.Conclusions.Helical tomotherapy for NPC patients achieved excellent 3-year locoregional control, distant metastasis-free survival, and overall survival, with relatively minor acute and late toxicities. Age and T stage were the main prognosis factors.

AbstractEarly prediction of treatment response in nasopharyngeal carcinoma is clinically relevant for optimizing treatment strategies. This meta-analysis was performed to evaluate whether apparent diffusion coefficient (ADC) from diffusion-weighted imaging (DWI) can predict treatment response of patients with nasopharyngeal carcinoma. A systematic search of PubMed-MEDLINE and Embase was performed to identify relevant original articles until July 22, 2021. We included studies which performed DWI for predicting locoregional treatment response in nasopharyngeal carcinoma treated with neoadjuvant chemotherapy, definitive chemoradiation, or radiation therapy. Hazard ratios were meta-analytically pooled using a random-effects model for the pooled estimates of overall survival, local relapse-free survival, distant metastasis-free survival and their 95% CIs. ADC showed a pooled sensitivity of 87% (95% CI 72–94%) and specificity of 70% (95% CI 56–80%) for predicting treatment response. Significant between-study heterogeneity was observed for both pooled sensitivity (I2 = 68.5%) and specificity (I2 = 92.2%) (P < 0.01). The pooled hazard ratios of low pretreatment ADC for assessing overall survival, local relapse-free survival, and distant metastasis-free survival were 1.42 (95% CI 1.09–1.85), 2.31 (95% CI 1.42–3.74), and 1.35 (95% CI 1.05–1.74), respectively. In patients with nasopharyngeal carcinoma, pretreatment ADC demonstrated good predictive performance for treatment response.

Purpose To evaluate the efficacy, safety, tolerability, and quality of life (QoL) in patients receiving intravenous, intermittent high-dose interferon alfa-2b (IFN-α-2b [iHDI]) compared with standard high-dose IFN-α-2b (HDI). Patient and Methods Patients with stage III resected lymph node or in-transit metastasis from cutaneous malignant melanoma were randomly assigned to receive either a standard HDI regimen or three courses of IFN-α-2b 20 MIU/m2 administered intravenously 5 days a week for 4 weeks then repeated every 4 months. Distant metastasis-free survival was the primary end point for efficacy analysis. In addition, relapse-free survival, overall survival, safety as determined by Common Terminology Criteria for Adverse Events criteria, and QoL were secondary end points. Results Of 649 patients enrolled, 22 patients were excluded from the intent-to-treat analysis. The remaining 627 patients were well balanced between the arms according to sex, age, and stage. After a median follow-up of 55 months, a multivariable Cox model revealed no significant differences for distant metastasis-free survival (hazard ratio [HR], 1.21; P = .12) or overall survival (HR, 1.01; P = .85). In contrast, the difference for relapse-free survival was significant (HR, 1.27; P = .03), favoring standard HDI. Early termination of treatment because of adverse events or QoL occurred significantly more often with HDI than with iHDI (26.0% v 14.8%; P < .001). Conclusion Although the safety and QoL profiles for the intermittent regimen were favorable, no significant difference was observed for survival while the HR for relapse with iHDI was increased. Therefore, an iHDI regimen, as tested here, cannot be recommended as adjuvant treatment for high-risk melanoma.

Mitochondrial DNA (mtDNA) mutations are highly associated with cancer progression. The poor prognosis of hepatocellular carcinoma (HCC) is largely due to high rates of tumor metastasis. This emphasizes the urgency of identifying these patients in advance and developing new therapeutic targets for successful intervention. However, the issue of whether mtDNA influences tumor metastasis in hepatoma remains unclear. In the current study, multiple mutations in mtDNA were identified by sequencing HCC samples. Among these mutations, mitochondrially encoded 12S rRNA (MT-RNR1) G709A was identified as a novel potential candidate. The MT-RNR1 G709A polymorphism was an independent risk factor for overall survival and distant metastasis-free survival. Subgroup analysis showed that in patients with cirrhosis, HBV-related HCC, α-fetoprotein ≥ 400 ng/mL, aspartate transaminase ≥ 31 IU/L, tumor number > 1, tumor size ≥ 5 cm, and histology grade 3-4, MT-RNR1 G709A was associated with both shorter overall survival and distant metastasis-free survival. Mechanistically, MT-RNR1 G709A was clearly associated with hexokinase 2 (HK2) expression and unfavorable prognosis in HCC patients. Our data collectively highlight that novel associations among MT-RNR1 G709A and HK2 are an important risk factor in HCC patients.

Abstract Objectives The value of using PET/CT for staging of stage I–II NPC remains unclear. Hence, we aimed to investigate the survival benefit of PET/CT for staging of early-stage NPC before radical therapy. Methods A total of 1003 patients with pathologically confirmed NPC of stages I–II were consecutively enrolled. Among them, 218 patients underwent both PET/CT and conventional workup ([CWU], head-and-neck MRI, chest radiograph, liver ultrasound, bone scintigraphy) before treatment. The remaining 785 patients only underwent CWU. The standard of truth (SOT) for lymph node metastasis was defined by the change of size according to follow-up MRI. The diagnostic efficacies were compared in 218 patients who underwent both PET/CT and CWU. After covariate adjustment using propensity scoring, a cohort of 872 patients (218 with and 654 without pre-treatment PET/CT) was included. The primary outcome was overall survival based on intention to treat. Results Retropharyngeal lymph nodes were metastatic based on follow-up MRI in 79 cases. PET/CT was significantly less sensitive than MRI in detecting retropharyngeal lymph node lesions (72.2% [62.3–82.1] vs. 91.1% [84.8–97.4], p = 0.004). Neck lymph nodes were metastatic in 89 cases and PET/CT was more sensitive than MRI (96.6% [92.8–100.0] vs. 76.4% [67.6–85.2], p < 0.001). In the survival analyses, there was no association between pre-treatment PET/CT use and improved overall survival, progression-free survival, local relapse-free survival, regional relapse-free survival, and distant metastasis-free survival. Conclusions This study showed PET/CT is of little value for staging of stage I–II NPC patients at initial imaging. Key Points • PET/CT was more sensitive than MRI in detecting neck lymph node lesions whereas it was significantly less sensitive than MRI in detecting retropharyngeal lymph node lesions. • No association existed between pre-treatment PET/CT use and improved survival in stage I–II NPC patients.

Abstract PurposeTo investigate the survival difference between limited axillary surgery and full axillary lymph node dissection (ALND) in patients with 1-3 positive sentinel lymph node biopsies (SLNBs) after neoadjuvant chemotherapy (NAC).MethodWe retrospectively analyzed data from 676 patients who underwent surgery between 2007 and 2017 with cT1-4, cN0-3, cM0 breast cancer at the time of diagnosis and 1-3 positive SLNBs after NAC. The patients received either SLNB only or completed level I or II ALND based on SLNB results. After propensity score matching, 483 patients who had undergone SLNB only (n=188) and ALND (n=295) were included. We examined overall survival, axillary recurrence-free survival, regional recurrence-free survival, and distant metastasis-free survival and compared them between the subgroups.ResultAt a median follow-up of 59.4 months, no significant statistical difference was observed in overall survival, axillary recurrence-free survival, regional recurrence-free survival, and distant metastasis-free survival between SLNB only and ALND. No significant differences were observed in the 5-year axillary recurrence-free survival (93.1% vs. 94.0%, hazard ratio [HR]=0.94, 95% confidence interval [CI]=0.43-2.05, p=0.876) and 5-year overall survival (97.7% vs. 97.3%, HR=1.65, 95% CI=0.58-4.65, p=0.347) between the two groups.ConclusionOur analysis suggests that SLNB alone may be a possible option for patients with 1-3 sentinel node-positive breast cancer following NAC without significant compromise of recurrence or overall survival.

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.
