Objectives: To address controversies regarding target volume delineation for adjuvant intensity-modulated radiation therapy for oral cavity squamous cell carcinoma with pedicled flap reconstruction and elective nodal irradiation (ENI).
Materials And Methods: During target volume delineation, the primary tumor bed was the pre-surgical gross tumor volume with an additional isotropic margin of 5-10 mm. Additionally, the flap and body tissue junction were given a margin of 5-10 mm (if not already given).
Background: The aim of this study was to document the incidence, spectrum and outcomes of Second Primary Malignancy (SPM) in a prospectively followed-up population of Head and Neck Squamous carcinoma (HNSCC) patients accrued in six prospective trials and treated with definitive radiotherapy.
Materials And Methods: Patients were prospectively followed up over time and data on SPM collected after IRB approval after establishing the diagnosis of SPM based on clinical criteria. Descriptive statistics to determine clinic demographic characteristics and spectrum of SPM encountered, time to event outcomes (SPM-DFS - Disease-free survival after diagnosis of second primary, SPM-OS - Overall survival after diagnosis of second primary) and univariate analysis of factors of likely prognostic significance were performed.
Background: This study reports the psychometric properties of OUTPASAT-35RT questionnaire from a large Indian cancer cohort treated with ambulatory radiotherapy (RT) at a tertiary-care comprehensive cancer center.
Materials And Methods: Adults with a pathologically proven diagnosis of cancer undergoing fractionated RT (≥10 fractions) with the ability to read and understand English, Hindi, or Marathi were accrued after written informed consent. Patients were administered a language-appropriate version of OUTPATSAT-35RT along with European Organization for Research and Treatment of Cancer (EORTC) generic quality-of-life questionnaire (QLQ-C30) at conclusion of RT (±3 days).
Background: Virtual surgical planning (VSG), also known as computer-assisted reconstruction, has started to become the norm for more complex patients in many centers in recent times.
Aim: This study was conducted to evaluate the VSG in maxillofacial reconstruction surgery.
Methods And Materials: This study included 20 patients who underwent surgery for maxillofacial reconstruction.
Background: The care of adolescents and young adults (AYAs) with bone sarcomas involves unique challenges. The objectives of this study were to identify challenges and evaluate long-term outcomes of these patients from India who received treatment with novel protocols.
Methods: This prospective cohort study included AYA patients (aged 15-39 years) with osteosarcoma and Ewing sarcoma (ES), who were treated uniformly at the authors' institute using unique protocols (OGS-12 and EFT-2001) from 2011 to 2021 and from 2013 to 2018, respectively.

Aims: Over the past two decades, significant progress has been made in the development of quality indicators (QIs) within the field of radiotherapy (RT). However, most of the literature has predominantly focused on process and outcome-related QIs, with limited attention given to structural QIs. This review aims to address this gap by providing insights into structural QIs in RT and examining the complexities and considerations involved in establishing universal standards for these indicators across RT facilities globally.

Previous studies have identified inconsistencies in endpoint definitions across oncological clinical trials. Here, the Head and Neck Cancer International Group assessed endpoint definitions from phase 3 trials or trials considered practice-changing for patients with recurrent or metastatic mucosal head and neck squamous cell carcinoma, published between 2008 and 2021.

Objective: To evaluate the imaging features and diagnostic accuracy of computed tomography (CT) in liver tumors in children under 2 years.
Purpose: Desmoid fibromatosis (DF) is a locally aggressive tumor with low mortality but significant morbidity. There is a lack of standard of care, and existing therapies are associated with significant barriers including access, cost, and toxicities. This study aimed to explore the efficacy and safety of the metronomic therapy (MT) in DF in a large, homogenous cohort from India.

The study developed Artificial Neural Network (ANN) models to predict proton beam spot size and relative positional errors using 9000 proton spot data. The irradiation log files as input variables and corresponding scintillation detector measurements as the label values.

This non-toxic leaf-component regressed cancerous murine tumors (melanoma, carcinoma, sarcoma) recurrently in different experimental circumstances by boosting prime antitumor immune attributes. Such antitumor immunomodulation, aid cytotoxic T cell (T)-based annihilation of tumor cells.

This study was undertaken to assess the clinical outcomes in terms of event free survival, local failure free survival and overall survival in individuals with advanced HL treated with chemotherapy and CRT.
Methods: A retrospective review was conducted to study the long-term clinical outcomes in individuals diagnosed with HL and treated with chemotherapy and CRT from 2012 to 2016 at a tertiary cancer care hospital in India.
Background: The efficacy of extracorporeal membrane oxygenation (ECMO) as a bridge to left ventricular assist device (LVAD) remains unclear, and recipients of the more contemporary HeartMate 3 (HM3) LVAD are not well represented in previous studies. We therefore undertook a multicenter, retrospective study of this population.
Methods And Results: INTERMACS 1 LVAD recipients from five U.
It is of interest to compare conventional lateral window technique, trans-alveolar technique with minimally invasive technique like modified trephine technique and antral membrane balloon elevation technique for sinus floor elevation in placement of dental implants. The current study included 140 participants (191 dental implants) who had maxillary posterior edentulous regions and had low sinuses and insufficient alveolar ridges but had chosen an implant-retained prosthesis. The minimally invasive techniques of sinus augmentation can be suitable alternative to conventional traumatic techniques due to low incidence of pain, gingival swelling.

Materials And Methods: A retrospective observational study of 44 patients with 51 lesions was carried out from year 2005 to 2020. MR images were reviewed for characteristics of carotid body tumor, and a score was given that was correlated with intra- and postoperative findings.
Background: Neoadjuvant chemotherapy (NACT) with TPF (docetaxel, cisplatin, and 5FU) is one of the treatment options in very locally advanced oral cancer with a survival advantage over PF (cisplatin and 5FU). TP (docetaxel and cisplatin) has shown promising results with a lower rate of adverse events but has never been compared to TPF.
Methods: In this phase 3 randomized superiority study, adult patients with borderline resectable locally advanced oral cancers were randomized in a 1:1 fashion to either TP or TPF.
Purpose: This study aimed to evaluate the volumetric and geometric changes in the parotid glands and target volume during image-guided radiotherapy (IGRT) for locally advanced oropharyngeal cancers.
Materials And Methods: Twenty patients receiving radiotherapy using IGRT at a dose of 70 Gy/35 fractions/7 weeks for locally advanced oropharyngeal cancers were accrued. Radiotherapy planning computed tomography (CT) scans were performed at pre-radiotherapy (RT), 20, 40, and 60 Gy for each patient.
This study's objective was to compare detection rates of radiograph, computed tomography (CT), and positron emission tomography-contrast-enhanced computed tomography (PET-CECT) for pulmonary metastasis/synchronous primary lung tumors in head and neck squamous cell cancer (HNSCC) and its association with clinico-radio-pathological factors. Our retrospective study included 837 HNSCC patients from January 2012 to December 2017. Lung nodules were characterized on CT as benign, indeterminate, and metastatic.

A shortfall in specialised workforce has been identified as the most significant barrier to expanding radiotherapy capacity. Artificial intelligence (AI)-based software has been developed to automate both the delineation of anatomical target structures and the definition of the position, size and shape of the radiation beams.

The 3-drug NACT regimen (Docetaxel-Cisplatin-5-FU) has shown improvement in overall survival over 2-drug regimen (Docetaxel-Cisplatin) in a phase-3 randomised study. We have analysed the 10-year outcomes with this treatment algorithm.
