The 2018 revised International Federation of Gynaecology and Obstetrics (FIGO) staging of cervical cancer has brought about a paradigm shift by offering the option of adding imaging and pathology to clinical staging. This makes it applicable to all types of resource situations across geographies with implications for all stakeholders, including gynaecologists, gynaecologic oncologists, radiologists, pathologists and radiation and medical oncologists. The new staging classification has more granularity, with three sub-stages of stage IB and a new category of stage IIIC for all cases with lymph node (LN) involvement. ⋯ Although any imaging modality can be used, magnetic resonance imaging appears to be the best imaging modality for early-stage disease owing to its better soft-tissue resolution. However, the use of contrast-enhanced computed tomography or ultrasonography are also feasible options, depending on the availability and resources. But wherever pathological evaluation is possible, it supersedes clinical and radiological findings.

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.

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.

Globally, cervical cancer has the fourth highest cancer incidence and mortality in women. Cervical cancer is unique because it has effective prevention, screening, and treatment options. ⋯ Topics discussed include diagnostic imaging principles, surgical management with adjuvant therapy and definitive concurrent chemoradiotherapy. Emphasis is given on current advances and future research directions in radiation therapy (RT) with an emphasis on three-dimensional brachytherapy, intensity-modulated RT, image-guided RT, proton RT and hyperthermia.

Locally advanced cervical cancer with the involvement of para-aortic lymph nodes (PALN) is a common occurrence in low-income and low-middle-income countries. With the incorporation of PALN in the recent FIGO staging, therapeutic management becomes crucial. ⋯ With recent advances in radiation therapy, its application to treat bulky nodal metastases and the role of prophylactic irradiation have been reported. In this review, the available evidence and the scope of further interventions is presented.
