Cervical cancer is one of the most common cancers in developing nations. It has had a tremendous impact on the lifetime of millions of women over the last century and continues to do so. In this collaborative clinicians' review, we highlight the incidence, treatment and clinical outcomes of cervical cancer in low-income (LICs) and low- and middle-income countries (LMICs) across Asia, South America, South Africa and Eastern Europe. With the cervical cancer burden and locally advanced cancers bein...

Purpose null To test effects of positron emission tomography (PET)-based bone marrow-sparing (BMS) image-guided intensity modulated radiation therapy (IMRT) on efficacy and toxicity for patients with locoregionally advanced cervical cancer. null Methods and materials null In an international phase II/III trial, patients with stage IB-IVA cervical carcinoma were treated with either PET-based BMS-IG-IMRT (PET-BMS-IMRT group) or standard image-guided IMRT (IMRT group), with concurrent cisplatin (40...

Summary Background The COVID-19 pandemic has disrupted health-care systems, leading to concerns about its subsequent impact on non-COVID disease conditions. The diagnosis and management of cancer is time sensitive and is likely to be substantially affected by these disruptions. We aimed to assess the impact of the COVID-19 pandemic on cancer care in India. Methods We did an ambidirectional cohort study at 41 cancer centres across India that were members of the National Cancer Grid of India to co...

Abstract null null Introduction null In 2020, the ESTRO course on image-guided radiotherapy and chemotherapy in gynaecological cancer was converted into an online version due to the COVID-19 pandemic. This paper describes the change process and evaluates the impact on participants compared with previous live courses. null null null Methods and Materials null The 2019 live course contained 41 hours of educational content, comprising 33 hours of synchronous activities (lectures, interactive activi...

SUMMARY null null The manuscript is based on the dosimetric and clinical outcome of a prospective phase II study in locally advanced cervical cancer patients to evaluate the feasibility and safety to deliver HDR brachytherapy in a single application and multiple fractions delivering >84 Gy EQD2 to the adaptive target while achieving strict dose constraints to organs at risk. We believe that this is the first prospective study evaluating feasibility of delivering brachytherapy over 2 days in sing...

PURPOSE Chemoradiation remains a challenge in women living with HIV (WLWH) and cervical cancer primarily because of concerns regarding immune status. With limited literature available to help guide the management of these patients, clinical practices among oncologists are variable across India. Hence, we conducted a survey among radiation oncologists in India to assess the patterns of current practices of treating cervical cancer with chemoradiation in WLWH. MATERIALS AND METHODS A questionnaire...

Abstract MR Imaging is regarded as the gold standard for Image Gudied Adaptive Brachytherapy (IGABT) for cervical cancer. However, its wide applicability is limited by its availability, logistics and financial implications. Use of alternative imaging like CTand Ultrasound (US) for IGABT has been attempted. In order to arrive at a systematic, uniform and international approach for CT based definition and contouring of target structures, GEC ESTRO, IBS and ABS agreed to jointly develop such recomm...
