An Analysis of Radiotherapy Machine Requirements in India: Impact of the Pandemic and Regional Disparities.

Aim: This article examines India's present radiotherapy (RT) machine status and requirements, geographical distribution, and infrastructure need in six regional areas, which include 31 member states and union territories (UTs). It also considers the influence of the COVID-19 pandemic on India's teletherapy sector.

Materials And Methods: Data from reliable resources, including Atomic Energy Regulatory Board, Global Cancer Observatory, and Directory of Radiotherapy Centres databases, were used to analyze the current status of RT machine (RTM) density, regional disparity, and COVID-19 impact on infrastructure growth-rate.

Analyzing Global Cancer Control: Progress of National Cancer Control Programs through Composite Indicators and Regression Modeling.

Aim: Cancer is a significant public health concern, and National Cancer Control Programs (NCCPs) are crucial for reducing its burden. However, assessing the progress of NCCPs is challenging due to the complexity of cancer control outcomes and the various factors that influence them. Composite indicators can provide a comprehensive and accurate assessment of NCCP progress.

A comparative dose-escalation analysis for reirradiated cancer patients with and without appropriate dose mapping.

This study aims to compare dose escalation between two groups of reirradiated cancer patients, one with the previous contour and radiotherapy plan available on the treatment planning system and the other without. First group is identified as DICOM-group, while the other one is called non-DICOM group. The current study included 89 patients, 57 in the DICOM, and 32 in the non-DICOM group, who received reirradiation for recurrent or second primary tumours between 2019 and 2021.

Customizing Treatment Scheduling Windows with a Time Margin Recipe: A Single-institutional Study.

Purpose: Rising cancer incidences, complex treatment techniques, and workflows have all impacted the radiotherapy scheduling process. Intelligent appointment scheduling is needed to help radiotherapy users adapt to new practices.

Efficient and Reliable Data Extraction in Radiation Oncology using Python Programming Language: A Pilot Study.

Background And Purpose: In recent years, data science approaches have entered health-care systems such as radiology, pathology, and radiation oncology. In our pilot study, we developed an automated data mining approach to extract data from a treatment planning system (TPS) with high speed, maximum accuracy, and little human interaction. We compared the amount of time required for manual data extraction versus the automated data mining technique.

Calculation of set-up margin in frameless stereotactic radiotherapy accounting for translational and rotational patient positing error.

Context: Rotation corrected set-up margins in stereotactic radiotherapy (SRT).

Settings And Design: 6D setup errors for the steriotactic radiotherapy patients were converted to 3D translational only error mathematically.

Peer reviewers from low- and middle-income countries(LMIC) for open access journals in oncology can improve the equity in cancer research and clinical trials.

Open access journals (OAJ) in biomedicine are promoted to improve the reach and distribution of global health research (GHR). However, in the last 20 years, article publishing charge (APC) is attracting and publishing the vast majority of papers from high-income countries (HIC) in "oncology" journals under OAJ. This paper outlines the impediments for cancer research and publication from low-and middle-income countries (LMIC): (a) existing disparities in cancer care facilities and survival outcomes between HIC and LMIC, (b) more than 70 % of OAJ in 'oncology' subject levy APC, becoming unaffordable for scientists and clinicians from LMIC, (c) impactful OAJ in oncology engage less than 10 % of members from LMIC in editorial board or as peer reviewer, whereas two-third of cancer diagnosis and management occur in these countries.

Clinical management of stage III non-small cell lung cancer in India: An expert consensus statement.

Non-small cell lung cancer (NSCLC) is considered the most common type of lung cancer (>80% of all lung cancers); patients are often diagnosed at advanced stages of the disease. The management of NSCLC is considered challenging owing to variations in size, an extension of the tumors, involvement patterns, and classification. Although adequate literature and guidelines are available on the management of NSCLC in several countries, an Indian perspective on stage III NSCLC management is lacking.

Audit of radiation oncology practice: Lessons from a new private hospital in Delhi, India.

Aims: The objective of this audit was to analyze the radiotherapy (RT) practice in a newly established tertiary private hospital. With increasing radiation oncology (RO) facilities in private sector, this report is the first audit from a private health organization in India.

Subjects And Methods: The audit of all consecutively registered patients in RO has focused to extract data from the time of RT simulation planning till the completion of RT course.

Ensuring quality in contextualised cancer management guidelines for resource-constraint settings: using a systematic approach.

To address the wide variation in access to cancer care in India requires strengthening of infrastructure, trained oncology workforce, and minimisation of out-of-pocket expenditures. However, even with major investments, it is unlikely to achieve the same level of infrastructure and expertise across the country. Therefore, a resource stratified approach driven by evidence-based and contextualised clinical guidelines is the need of the hour.

An audit of Grade III or more skin reactions in consecutively assessed patients at a modern radiation oncology center.

Purpose: Radiation dermatitis is most common and debilitating side effects of radiotherapy leading to treatment interruption, thereby compromising the local control, and effecting quality of life. With the invent of modern imaging and recent advances in megavoltage radiotherapy, radiation-related side effects have reduced. In this audit, we report the risk factors associated with Grade III dermatitis in modern centers.

Relevance of multi-disciplinary team approach in diagnosis and management of Stage III NSCLC.

Lung cancer is reported as the leading cause of cancer-related mortality worldwide. Non-small cell lung cancer (NSCLC) constitutes 80%-85% of all lung cancers. Diagnosis of NSCLC is a complex multistep process.

Challenges faced by female radiation oncologists (FRO) in South Asia.

Aim: This study was designed to evaluate the personal challenges, work environment, and financial satisfaction of female radiation oncologists (FRO) in South Asia.

Collusion: The Facade and its Implications on Total Pain Management in Palliative Care.

Collusion is an unharmonious bond between the doctor and a patient or between patients and caregivers. This case report exemplifies one such experience and highlights the hurdles we face when dealing with collusion. A 31-year-old woman was diagnosed with rectal carcinoma during her pregnancy and underwent diversion colostomy (for intestinal obstruction) followed by neoadjuvant chemoradiation after delivery.

Rotational positional error-corrected linear set-up margin calculation technique for lung stereotactic body radiotherapy in a dual imaging environment of 4-D cone beam CT and ExacTrac stereoscopic imaging.

Objective: Accurate calculation of set-up margin is a prerequisite to arrive at the most optimal clinical to planning target volume margin. The aim of this study was to evaluate the compatibility of different on-board and in-room stereoscopic imaging modalities by calculating the set-up margins (SM) in stereotactic body radiotherapy technique accounting and unaccounting for rotational positional errors (PE). Further, we calculated separate SMs one based on residual positional errors and another based on residual + intrafraction positional errors from the imaging data obtained in a dual imaging environment.

Integrating psycho-oncology services in cancer care in India.

Psychological distress is often an under-diagnosed problem in cancer care. Addressing psychosocial issues would enhance treatment compliance, physician-patient relationship, treatment efficacy and quality of life. This article emphasizes the importance of integrating psycho-oncology services in cancer care and attempts to define the various roles that a psycho-oncologist can play across the entire trajectory.
