ver, larger studies are required to further prove the specificity and sensitivity.
Real-life data analysis of anti-PD1 use for solid cancers highlights that baseline NLR, PLR, NER, and LMR have a significant role as immunotherapy biomarkers. However, larger studies are required to further prove the specificity and sensitivity.
Malignant peripheral nerve sheath tumor (MPNST) is a rare and aggressive soft-tissue sarcoma.

The aim of this study was to analyze various prognostic factors and treatment outcome of patients with MPNST.

This was a retrospective study.

Ninety-two patients, who presented with MPNST at a tertiary care cancer center from 2011 to 2018, were included in this study. The median follow-up of all living patients was 33 months. Ivacaftor molecular weight Neurofibromatosis 1 (NF1) was seen in 12 (13%) patients. Sixty (65.2%) patients received curative-intent treatment.

Kaplan-Meier method was used for survival analysis. Log-rank test was used for univariate analysis, and multivariate analysis was done by Cox proportional hazard ratio method.

The 5-year overall survival (OS) of all patients was 47.2% and the 5-year disease-free survival (DFS) of operated patients was 41.5%. On univariate analysis, association with NF1 (P = 0.009), grade (P = 0.017), and margin status (P = 0.002) had a significant effect on DFS, whereas association withors associated with poor survival for the patients with MPNST. Wide local excision with negative resection margin is the highly recommended treatment.
Radiotherapy may have side effects on the brain, such as radiation necrosis, cognitive impairment, and a high chance of tumor recurrence, which has been considered the most common cause of treatment failure.

Using intensity-modulated radiotherapy (IMRT) and volumetric-modulated arc therapy (VMAT) techniques, we aimed to test the potential outcome of sparing the contralateral hippocampus (CLH) in radiotherapy for brain tumors by comparing dosimetric parameters.

A prospective clinical comparative study.

Using IMRT and VMAT, sparing CLH in radiotherapy of brain tumors was tested in ten patients, and various dosimetric parameters were compared. The treatment plans were accepted only if they met the set of planning objectives defined in the protocol.

The dose delivered to 95% of the CLH volume (CLH D95), and the mean (CLH Dmean) and max (CLH Dmax) doses were found to be significantly highest in the standard IMRT (P = 0.002, <0.001, and < 0.001, respectively). The lowest CLH D95, CLH Dmean and CLH Dmax for the hippocampus were detected in sparing VMAT planning than in the other plans (P < 0.05). None of the post hoc comparisons for CLH D95 was different among any of the plans, whereas the mean dose to CLH was statistically different among all paired comparisons (P < 0.008). The maximum dose to CLH was also statistically different among all paired plans (P < 0.008), except the dose difference between standard VMAT and IMRT plans.

Although VMAT planning is troublesome and time-consuming, the advantage of sparing the hippocampus is beneficial, preserving the hippocampus and cognitive functions during radiotherapy.

Acute esophagitis (AE) is a commonly encountered side effect of curative thoracic radiotherapy (CTRT) for lung cancer patients. Nevertheless, its identification for widely used scoring systems depends on patients' statements. It is aimed to evaluate the correlation between the esophagus doses during CTRT and Grade 1-2 AE, weight change, and change in serum albumin (Alb) levels.

The data collected from 124 lung cancer patients treated with ≥60 Gy CTRT were evaluated retrospectively. Weight and serum Alb level difference of each patient, throughout CTRT, were calculated. The percentage of the esophagus volume receiving ≥5 Gy (V5), V10, V35, V50, and V60; the absolute esophagus volume receiving ≥60 Gy (V60(cc)); the length of esophagus receiving ≥60 Gy (L60); the average esophagus dose (D
); and the maximum esophagus dose (D
) were the dose parameters calculated. The correlations were performed by Spearman's rank correlation coefficient.

Grade 1 and Grade 2 AE were reported in 62 and 25 patients, respectively. All of the dose parameters were correlated with Grade 1-2 AE (P < 0.001) and weight loss (P < 0.001 for all, except D
P = 0.018). Decrease in serum Alb level was significantly correlated with all the parameters, but V5 and V10. Receiver operating characteristic curve analysis was performed for five parameters with the highest correlation coefficient (V35, V50, V60(%), V60(cc), and D
), and the cutoff values were 39.5%, 28.17%, 2.21%, 0.5cc, and 26.04 Gy, respectively.

The correlation of the dose parameters that might be effective on Grade 1-2 AE with the weight loss and Alb loss was investigated, and the cutoff values corresponding to the best sensitivity and specificity were identified.

Relevance of aggressive treatment in advanced head neck squamous cell cancers(HNSCC) is debatable in view of expected poor outcome. Long treatment duration only adds up to the cost of treatment without any improvements in outcomes.

To assess the outcomes of hypofractionated "Christie" palliative radiotherapy regimen in advanced HNSCC.

Patients of advanced HNSCC registered from June 2015 to June 2019 were treated by parallel pair field technique on Cobalt60 machine (Theatron 780E) to total dose of 50 Gray/16 fractions over 3.2 weeks. Toxicity was scored using Radiation Therapy Oncology Group (RTOG) criteria and response was evaluated as per WHO criteria.

Records of 110 patients of HNSCC with mean age of 56.19 years were analysed. Evaluation at 4-8 weeks after radiotherapy resulted in a complete response (CR) in 19.1%, partial response (PR) in 32.7%, stable disease (SD) in 29.1% and progressive disease (PD) in 3.6%, while 15.5% patients did not report for post treatment evaluation. Median progression free survival was 9.
