Background: To retrospectively assess the impact of prognostic nutritional index (PNI) on survival outcomes of patients with locoregionally advanced nasopharyngeal carcinoma (LA-NPC) treated with concurrent chemoradiotherapy (CCRT). Methods: This study incorporated 154 patients with LA-NPC who received exclusive cisplatinum-based CCRT. Receiver operating characteristic (ROC) curve analysis was utilized for accessibility of pretreatment PNI cutoffs influencing survival results. The primary end point was the interaction between the overall survival (OS) and PNI values, while cancer-specific survival (CSS) locoregional progression-free survival (LR-PFS), distant metastasis–free survival (DMFS), and PFS were the secondary end points. Results: A rounded PNI cutoff value of 51 was identified in ROC curve analyses to exhibit significant link with CSS, OS, DMFS, and PFS outcomes, but not LR-PFS. Patients grouping per PNI value (≥51 [N = 95] vs <51 [N = 49]) revealed that PNI < 51 group had significantly shorter median CSS (P <.001), OS (P <.001), DMFS (P <.001), and PFS (P <.001) times than the PNI ≥ 51 group, and the multivariate results confirmed the PNI < 51 as an independent predictor of poor outcomes for each end point (P <.05 for each). The unfavorable impact of the low PNI was also continued at 10-year time point with survival rates of 77.9% versus 42.4%, 73.6% versus 33.9%, 57.9% versus 27.1%, and 52.6% versus 23.7% for CSS, OS, DMFS, and PFS, respectively. Additionally, we found that PNI < 51 was significantly associated with higher rates of weight loss >5% over past 6 months (49.2% versus 11.6%; P =.002) compared to PNI < 51 group. Conclusion: Low pre-CCRT PNI levels were independently associated with significantly reduced CSS, OS, DMFS, and PFS outcomes in patients with LA-NPC treated with definitive CCRT.

Purpose: To investigate the incidence and influence of tumor cavitation (TC) on survival outcomes of locally advanced squamous cell lung cancer (LA-SqCLC) patients treated with concurrent chemoradiation therapy (C-CRT).Methods and Materials: Records of 789 stages IIIA/B squamous cell lung cancer (SqCLC) patients treated with C-CRT who received 1 to 3 cycles of platinum-based doublet chemotherapy during 60 to 66 Gy radiation therapy (RT) were analyzed retrospectively. Primary endpoint was the association between overall survival (OS) and pretreatment TC status. Secondary endpoints included locoregional progression-free survival (LRPFS), progression-free survival (PFS), and incidence of TC and correlated factors.Results: Pretreatment TC occurred in 95 patients (12%), being significantly more common in those patients with ever-smoking history (12.6% vs 3.9%; P < .001), weight loss >5% (20.9% vs 7.1%; P < .001), and hemoptysis (27.1% vs 6.4%; P < .001). Rates of acute and late toxicities were similar in patients who presented with and without TC (P > .05 for each). For the whole cohort, at a median follow-up of 22.9 months (range: 2.4-71.1), the respective median OS, LRPFS, and PFS estimates were 23.7, 14.7, and 10.7 months. In multivariate analysis, stage IIIB disease (P < .001; hazard ratio [HR]: 1.33; 95% CI: 1.21-1.45), weight loss >5% (P < .001; HR: 2.10; 95% CI: 1.85-2.35), anemia (P < .001; HR: 1.82; 95% CI: 1.67-1.97), and presence of TC (P < .001; HR: 1.54; 95% CI: 1.37-1.71) appeared to be independently associated with poorer OS durations, likewise the LRPFS (P < .001 for each of these covariates), and PFS (P < .001 for each of these covariates), respectively.Conclusions: Present results showed that the TC occurred in 12% of LA-SqCLC patients, which was strongly associated with poorer PFS, LRPFS, and OS outcomes after definitive C-CRT.

Nearly half of all cancer patients unavoidably experience brain metastases (BM) somewhere during their disease course. Current treatment approaches include neurosurgery, wholebrain radiotherapy (WBRT), stereotactic radiosurgery (SRS), chemotherapy, and targeted agents which may be utilized either individually or as any combination, depending on the anticipated patient's prognosis. Radiotherapy, directed to whole-brain contents or exclusively the BMs, is the cornerstone of palliative management of patients with BM. This present review manuscript will particularly focus on the use of two well-established effective palliative radiotherapy modalities and their comparative effectiveness, namely the WBRT and SRS.

Bone metastases (BM) are experienced nearly by one of two of all cancer patients either at presentation or during the disease course. As a fundamental rule, because treatment of BM usually aims to palliate, the cardinal objectives of treatment should incorporate the attainment of a rapid and durable pain relief with preserved mobility and functionality without causing significant toxicity. With its favorable toxicity profile and an overall response rate of greater than 80%, radiotherapy (RT) is a wellrecognized as a palliative measure for treatment of BM. The present article will exclusively focus on the role of RT in the management of BM with a specific emphasis on the ongoing debate of fractionation and total dose schemes. [ABSTRACT FROM AUTHOR]
