A 52-year-old homemaker from Nashik has regained her strength just days after undergoing one of the rarest and most demanding cancer operations, providing new hope for patients diagnosed with tumours in the body's largest vein. Doctors at HCG Manavata Cancer Centre (HCGMCC), Nashik, successfully removed a large cancer growing from the inferior vena cava (IVC), the major vein that carries blood from the lower half of the body back to the heart. The woman was able to walk within three days of surgery and was discharged on the fifth day.

The patient had initially dismissed persistent abdominal pain as a dietary problem. When the pain gradually spread to her legs, she sought medical advice. An ultrasound detected a mass measuring about 9 cm in the upper abdomen. A CT scan raised suspicion of cancer involving the IVC, while a PET-CT scan and biopsy later confirmed a rare soft tissue cancer arising from the wall of the vein itself.

Such tumours, known as IVC leiomyosarcomas, account for only a tiny fraction of all soft tissue sarcomas and are considered among the rarest cancers seen by surgical oncologists. According to the National Cancer Institute, European Society for Medical Oncology (ESMO) and studies published in The Lancet Oncology, complete surgical removal remains the best chance for long-term survival because chemotherapy and radiotherapy alone have limited effectiveness against these tumours.

"During the operation, surgeons successfully removed the tumour along with an approximately 12 cm segment of the affected IVC. The procedure also involved complex vascular reconstruction to restore normal blood flow. Despite the extensive nature of the surgery, the patient's recovery was remarkable. She was able to walk comfortably within days and was discharged home on the fifth post-operative day. In over 15 years of practice, this is only the second such rare surgery that we have performed," said Prof. Dr Raj Nagarkar, Chief of Surgical Oncology & Robotic Services and Managing Director, KIMS Manavata Hospitals, HCG Manavata Cancer Centre and Six Sigma, Nashik.

Removing a tumour from the IVC is particularly challenging because the vein lies deep inside the abdomen and is closely surrounded by vital organs and major blood vessels. Surgeons must temporarily control blood flow, remove the diseased section and rebuild the vein so that circulation can safely continue. International cancer guidelines stress the importance of conducting these procedures exclusively by experienced multidisciplinary teams in specialised centres.

"What makes stories like these truly special is not just the complexity of the surgery but the courage shown by patients and their families. The operation was a high-risk procedure with significant technical challenges, but their faith in our team never wavered. Witnessing her leave the hospital with a smile just five days later serves as a powerful reminder of the importance of advancing cancer care. Such surgeries are possible only with the right expertise, infrastructure, teamwork, and experience," Dr Nagarkar concluded.
