New Delhi: Gallbladder cancer is a challenge because of its subtle progression and its tendency to escape early detection. Although it is a relatively rare form of cancer, it is often not diagnosed until it reaches an advanced stage, which has a significant effect on survival rates. The absence of a set of early symptoms, as is the case with other cancers, makes it a challenge to treat and is a major factor in its high mortality rate.
Dr Amanjeet Singh, Senior Director, GI Surgery, GI Oncology and Bariatric Surgery, Gastrosciences, Medanta, Gurugram, answered this for News9Live.
Although relatively uncommon worldwide, India carries a disproportionate burden, accounting for almost 10 percent of global cases. In northern India, especially among women, incidence can reach as high as 21.5 per 100,000 individuals. Important to note, most of these cases in India are often diagnosed at an advanced stage, when treatment options are limited and survival rates are poor.
The Hidden Nature of Gallbladder Cancer
The primary challenge in early detection of the cancers comes from the gall bladder’s location in the body, which is under the liver, which is not easily accessible to palpation, and the fact that initial symptoms in this case are almost vague, hardly causing any pain or discomfort. Even if the symptoms do occur, they are non-specific and include mild abdominal pain, nausea, or bloating. These symptoms can easily be attributed to common, benign problems.
Diagnosis typically occurs only when the tumor has considerably grown, invaded surrounding tissues, or caused obstruction, leading to visible signs like jaundice, significant weight loss, or severe abdominal pain. By this point, the cancer has frequently spread, making treatment far more complex.
The Critical Role of Targeted Screening
A major challenge here is the lack of awareness about gallbladder cancer and its risk factors. Although screening is not recommended for the general population due to the low prevalence rate, screening in high-risk populations appears promising. Those with chronic gallstones, which are hardened formations within the gallbladder that can cause chronic irritation if they are large or multiple, have a higher risk. Another risk factor is the “porcelain gallbladder,” a complication in which the gallbladder wall becomes calcified or hardened with calcium deposits, making it more susceptible to cancer.
In certain people, an abnormally positioned pancreaticobiliary junction permits the reverse flow of pancreatic juices into the gallbladder, causing chronic irritation to the lining of the gallbladder over time and making it more susceptible to cancer.
The good news is that there are advanced diagnostic tools available today that are helping in early detection. Non-invasive imaging, such as ultrasound, can pick up suspicious changes, while CT scans, MRI, and endoscopic ultrasound can give a clear view of the gallbladder and surrounding areas. Blood tests for tumor markers such as CA 19-9 can also provide a clue, although they are not conclusive.
Early Detection: A Path to Curative Treatment
Detecting gallbladder cancer early significantly improves outcomes. Patients diagnosed at an early stage have a 5-year survival rate of 30–40%, compared to only around 10% for those with locally advanced disease. In its initial stages, gallbladder cancer can often be cured through surgery (cholecystectomy), sometimes combined with the removal of adjacent liver tissue and lymph nodes. For advanced cases, chemotherapy and radiation are used mainly to control symptoms, as curative options become limited.
Conclusion
Gallbladder cancer’s silent progression makes it one of the most challenging cancers to treat. In India, where many cases are diagnosed late, raising awareness and promoting targeted screening in high-risk groups is vital. With the availability of advanced imaging and diagnostic tools, there is now real hope of catching this cancer earlier, where curative treatment is possible. Continued improvements in detection and therapy remain central to saving lives from this aggressive disease.
