Breast cancer is the most common cancer among women in India, and adjuvant radiotherapy is an integral part of curative treatment in most patients. The recent decades have witnessed several advances in radiation therapy delivery. Several advances in radiation oncology have been identified which include technological advances, change in fractionation used, use of cardiac-sparing radiotherapy as well as efforts to personalize radiotherapy using accelerated partial breast irradiation or avoidance of radiotherapy in certain subpopulations. ⋯ However, increasing emphasis on research in these areas is needed so that effectiveness and safety in our setting can be established. Advances in breast cancer radiotherapy have resulted in improved outcomes. Data published from India suggest that these improved outcomes can be replicated in patients when appropriate treatment protocols are followed.

Aetiology of cervical cancer (CaCx) is multifactorial. Besides human papillomavirus (HPV) infection, many immunogenetic factors are involved in this complex process. The present study was carried out to investigate one such factor, interleukin-6 (IL-6), a central pro-inflammatory cytokine and a polymorphism at its promoter region -174 G/C (rs1800795) with CaCx. ⋯ Our results suggested a possible association of IL-6-174 GG with CaCx, which was also associated with high IL-6 levels. Decreased levels of IL-6 following treatment indicate its possible prognostic use in CaCx cases.

Cervical cancer is the fourth most common cancer in women in the world. To eliminate cervical cancer by 2030, the World Health Organization has given the target of 70 per cent coverage of twice lifetime screening. A multitude of screening methods are available, including cytology, human papillomavirus (HPV) DNA testing and visual inspection tests. ⋯ Worldwide HPV DNA testing with or without cytology is used as a screening method of choice, while in resource-poor settings, visual inspection tests are recommended. The major hurdle is a uniform and systematic implementation with a recall method in the population. Besides, controversies still exist regarding strategies to manage HPV-positive women and developing guidelines to screen the vaccinated population.

Review
Contribution of Tata Memorial Centre, India, to cervical cancer care: Journey of two decades.
Cervical cancer continues to be a major public health concern in India and other low- and middle-income countries. Tata Memorial Centre, India, has been at the forefront in providing treatment, developing best practice guidelines for low-cost efficacious interventions, conducting practice-changing randomized trials and engaging in regional and international collaborations for education and research in cervical cancer. This review summarizes how cervical cancer research and clinical care has evolved over the past two decades at the Tata Memorial Centre, right from testing low-cost public health screening of cervical cancers to the incorporation of the latest technological advancements and providing high-quality evidence for therapeutic management of cervical cancer. The various ongoing strategies for improving survival, toxicity reduction, translational research studies, educational activities and teaching programmes initiated by the Tata Memorial Centre at both national and international levels are discussed.

Chemoradiation is the standard therapy for locally advanced invasive cervical cancer and response to treatment determines the outcome. Cancer stem cells (CSCs) and epithelial-mesenchymal transition (EMT) play a role in response to treatment and hence the aim of this study was to evaluate if their levels in pre-treatment biopsies by immunohistochemistry (IHC) could predict response to treatment and outcome. ⋯ Determination of ALDH1 levels in pre-treatment cervical biopsies of invasive cervical carcinoma may be useful for prediction of response to chemoradiation, with high levels predicting for a poor response.
