New guidelines aim to reduce bowel cancer risk, offer framework for Indian healthcare adaptation

By A Representative

A new set of clinical guidelines has been released to improve monitoring and early detection of bowel cancer among patients with Inflammatory Bowel Disease (IBD), including Crohn’s disease and ulcerative colitis. The guidelines, developed for the British Society of Gastroenterology, are the result of a multi-institutional effort involving Newcastle University, Oxford University, the University of Central Lancashire, and others. The research is published in the UK journal Gut and was supported by the NIHR Biomedical Research Centres in Newcastle and Oxford.

Despite advancements in treatment and regular health monitoring, people with IBD continue to face significantly higher risks of developing and dying from colorectal cancer compared to the general population. The new guidelines provide evidence-based recommendations for risk assessment, colonoscopy timing, and surveillance protocols. Key among the recommendations is that all IBD patients undergo a colonoscopy around eight years after the onset of symptoms. Those with primary sclerosing cholangitis—a rare liver and bile duct condition often co-occurring with IBD—are advised to have a colonoscopy at the time of diagnosis.

The guidelines were shaped through an extensive review of over 7,500 scientific publications, resulting in 73 statements intended to guide clinicians in delivering effective surveillance services. Contributors included gastroenterologists, endoscopists, surgeons, specialist nurses, and patient representatives.

Professor Chris Lamb, Professor of Gastroenterology at Newcastle University and a co-author of the study, emphasized the patient-centered nature of the initiative. “Working in partnership with patients and clinicians, we’ve created a framework that combines the latest evidence, technology, and expert opinion to deliver personalized risk prediction and care,” he said.

Co-lead author Professor James East from Oxford University Hospitals NHS Foundation Trust noted that the guidelines offer clinicians comprehensive tools for tailoring care to individual patient needs. “They help clinicians determine when to begin or stop surveillance, how often to conduct it, and how to effectively communicate cancer risks with patients,” he said.

Professor Morris Gordon of the University of Central Lancashire, also a co-lead author, described the guidelines as a “significant shift in approach” due to their rigorous and transparent methodology in assessing clinical evidence.

Catherine Winsor, Director of Services and Evidence at Crohn's & Colitis UK, welcomed the guidelines, stating, “While most people with IBD will not develop colorectal cancer, early detection is crucial. These guidelines provide a clear path for timely diagnosis and improved outcomes.”

India is currently experiencing a sharp rise in IBD cases, especially in urban areas—a trend linked to factors such as changing diets, urbanisation, and improved sanitation. However, the country lacks standardized national guidelines for IBD management. Indian clinicians often rely on international frameworks, including those from the European Crohn’s and Colitis Organisation (ECCO). The newly released UK guidelines present an important opportunity for India to localize global best practices. Adoption and adaptation of these evidence-based recommendations could enhance early cancer detection, standardize IBD care, and ultimately improve outcomes for thousands of Indian patients.

Three foundational research papers have already been published to support the new guidelines: Low-coverage whole genome sequencing of low-grade dysplasia strongly predicts advanced neoplasia risk in ulcerative colitis; Comparative Efficacy and Safety of Endoscopic Modalities for Colorectal Cancer Screening in Inflammatory Bowel Disease; and Protocol for the 2024 British Society of Gastroenterology Guidelines on Colorectal Surveillance in IBD.

Newcastle University, a member of the UK’s Russell Group of research-intensive universities, is home to over 28,000 students from 130+ countries. The institution is recognized globally for its research excellence and is ranked 110th in the QS World University Rankings 2024 and 139th in the Times Higher Education World University Rankings 2023.

Was Netaji forced to alter face, die in obscurity in USSR in 1975? Was he so meek?

By Rajiv Shah This should sound almost hilarious. Not only did Subhas Chandra Bose not die in a plane crash in Taipei, nor was he the mysterious Gumnami Baba who reportedly passed away on 16 September 1985 in Ayodhya, but we are now told that he actually died in 1975—date unknown—“in oblivion” somewhere in the former Soviet Union. Which city? Moscow? No one seems to know.

Swami Vivekananda's views on caste and sexuality were 'painfully' regressive

By Bhaskar Sur* Swami Vivekananda now belongs more to the modern Hindu mythology than reality. It makes a daunting job to discover the real human being who knew unemployment, humiliation of losing a teaching job for 'incompetence', longed in vain for the bliss of a happy conjugal life only to suffer the consequent frustration.

Love letters in a lifelong war: Babusha Kohli’s resistance in verse

By Ravi Ranjan* “War does not determine who is right—only who is left.” Bertrand Russell’s words echo hauntingly in our times, and few contemporary Hindi poets embody this truth as profoundly as Babusha Kohli. Emerging from Jabalpur, Madhya Pradesh, Kohli has carved a unique space in literature by weaving together tenderness, protest, and philosophy across poetry, prose, and cinema. Her work is not merely artistic expression—it is resistance, refuge, and a call for peace.

Buddhist shrines were 'massively destroyed' by Brahmanical rulers: Historian DN Jha

Nalanda mahavihara By Rajiv Shah Prominent historian DN Jha, an expert in India's ancient and medieval past, in his new book , "Against the Grain: Notes on Identity, Intolerance and History", in a sharp critique of "Hindutva ideologues", who look at the ancient period of Indian history as "a golden age marked by social harmony, devoid of any religious violence", has said, "Demolition and desecration of rival religious establishments, and the appropriation of their idols, was not uncommon in India before the advent of Islam".

Asbestos contamination in children’s products highlights global oversight gaps

By A Representative A commentary published by the International Ban Asbestos Secretariat (IBAS) has drawn attention to the challenges governments face in responding effectively to global public-health risks. In an article written by Laurie Kazan-Allen and published on March 5, 2026, the author examines how the discovery of asbestos contamination in children’s play products has raised questions about regulatory oversight and international product safety. The article opens by reflecting on lessons from the COVID-19 pandemic, noting that governments in several countries were slow to respond to early warning signs of the crisis. Referring to the experience of the United Kingdom, the author writes that delays in implementing protective measures contributed to “232,112 recorded deaths and over a million people suffering from long Covid.” The commentary uses this example to illustrate what it describes as the dangers of underestimating emerging threats. Attention then turns...

India’s green energy push faces talent crunch amidst record growth at 16% CAGR

By Jag Jivan* A new study by a top consulting firm has found that India’s cleantech sector is entering a decisive growth phase, with strong policy backing, record capacity additions and surging investor interest, but facing mounting pressure on talent supply and rising compensation costs .

The kitchen as prison: A feminist elegy for domestic slavery

By Garima Srivastava* Kumar Ambuj stands as one of the most incisive voices in contemporary Hindi poetry. His work, stripped of ornamentation, speaks directly to the lived realities of India’s marginalized—women, the rural poor, and those crushed under invisible forms of violence. His celebrated poem “Women Who Cook” (Khānā Banātī Striyāṃ) is not merely about food preparation; it is a searing indictment of patriarchal domestic structures that reduce women’s existence to endless, unpaid labour.

The price of silence: Why Modi won’t follow Shastri, appeal for sacrifice

By Arundhati Dhuru, Sandeep Pandey* In 1965, as India grappled with war and a crippling food crisis, Prime Minister Lal Bahadur Shastri faced a United States that used wheat shipments under the PL-480 agreement as a lever to dictate Indian foreign policy. Shastri’s response remains legendary: he appealed to the nation to skip one meal a day. Millions of middle-class households complied, choosing temporary hunger over the sacrifice of national dignity. Today, India faces a modern equivalent in the energy sector, yet the leadership’s response stands in stark contrast to that era of self-reliance.

Beyond sattvik: Purity, caste and the politics of the Indian kitchen

By Rajiv Shah A few week ago, I was forwarded an article that appeared in the British weekly The Economist . Titled “Caste and cuisine: From honeycomb curry to blood fry: India’s ‘untouchable’ cooking”, it took me back to what I had blogged about what was called a “ sattvik food festival”, an annual event organised by former Indian Institute of Management-Ahmedabad professor Anil Gupta.
