Objective: The assessment of prognostic nutritional index (PNI) before and during radiotherapy is an important parameter for the prognosis in patients with cancer. In this study, enteral tube feeding (ETF) was used during radiotherapy in patients with EC. Dynamic changes of various nutritional indicators (including PNI) were monitored.
Methods: Patients with EC who underwent radiotherapy between June 2016 and July 2017 were enrolled. ETF was performing with the energy of 25 kcal × kg/d. Nutritional status were evaluated. Least significant difference (LSD) was used for multiple comparisons between groups.
Results: A total of 148 patients were admitted, including 51 patients fed via ETF. For patients who were not scheduled to nutritional support, significant difference were observed in albumin (ALB) (P < 0.001), prealbimnin (PA) (P = 0.05) and PNI (P < 0.001) compared to levels before radiotherapy. In the patients fed via enteral tube, no significant difference were found in weight, BMI, ALB, retinol binding protein (RBP) and PA before and after radiotherapy, while PNI significantly decreased (P < 0.001).
Conclusion: After preforming ETF with the energy of 25 kcal × kg/d in patients with EC during radiotherapy, PNI, the key nutritional index reflecting prognosis, significantly decreased.

Revealing the Enigma: A Deep Dive Into Submandibular Adenoid Cystic Carcinoma and Its Management.
Cureus
November 2024
Radiation Oncology, Faculty of Medicine and Pharmacy - Mohammed First University, oujda, MAR.
Adenoid cystic carcinoma (ACC) of the submandibular gland is a rare and highly aggressive malignancy, distinguished by its tendency for perineural invasion and distant metastasis, particularly to the lungs and bones. The management of ACC is challenging due to its biological variability and the absence of specific randomized controlled trials to guide treatment. This report aims to encapsulate the clinical features, histological profile, diagnostic workup, and management options for submandibular gland ACC, with an emphasis on recent advancements in understanding and treatment.

This study aims to assess the predictive value of certain markers of inflammation in patients with locally advanced or recurrent/metastatic cervical cancer who are undergoing treatment with anti-programmed death 1 (PD-1) therapy. A total of 105 patients with cervical cancer, who received treatment involving immunocheckpoint inhibitors (ICIs), were included in this retrospective study. We collected information on various peripheral blood indices, including the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), and prognostic nutritional index (PNI).

Medical University Heidelberg, Heidelberg, Baden-Württemberg, Germany.
This study sought to comprehensively evaluate the diagnosis, therapeutic interventions, and outcomes of individuals afflicted with malignant parotid tumors at a tertiary care otolaryngology department in Heilbronn, Germany, spanning the years 2010-2018. The primary objective was to juxtapose this dataset with findings from analogous single and multicenter investigations. We conducted a meticulous analysis of electronic medical records pertaining to 45 patients subjected to primary parotid cancer treatment.

Materials And Methods: This was a longitudinal retrospective observational study on 470 head and neck cancer inpatients who were to undergo radiotherapy from a grade-A tertiary hospital in Hunan Province between July 2022 and October 2023. The latent class growth model and growth mixed model were used to identify PNI trajectory categories.
The impact of worst patterns of invasion on survival outcomes in oral cavity cancer: implications for adjuvant therapy and prognostic stratification.

Purpose: To examine the impact of the worst patterns of invasion (WPOI) on survival outcomes and possible implications for adjuvant treatment decisions in squamous cell oral cavity cancer patients.
Methods: The loco-regional progression-free survival (LRPFS) and the distant metastasis-free survival (DMFS) were calculated for 162 patients. Univariate and multivariate analyses were done according to prognostic predictors of stage (early/T1-2 or N0; locally advanced /T3-4 or N +), grade, depth of invasion, WPOI, perineural (PNI), and lymphovascular (LVI) invasion and margin status.
