Inner Mongolia International Mongolian Hospital reported on 23 October that a 51-year-old woman from Mongolia had undergone cytoreductive surgery for primary peritoneal cancer following diagnosis and chemotherapy at the hospital. The operation took place on 21 September 2026. At the time of publication, the hospital described stable vital signs, steadily improving test results and good postoperative recovery.

From an uncertain diagnosis to treatment in China

In June 2026, the patient was admitted to a hospital in Mongolia with lower abdominal pain. Pathology after an appendectomy identified a malignancy of uncertain origin. She then sought care in the Chinese hospital's gynaecology department.

After multidisciplinary consultation, she underwent an initial operation under general anaesthesia: partial omentectomy, removal of peritoneal tumour and adhesiolysis in the pelvis and abdomen. Frozen-section examination of the removed mass was consistent with invasive adenocarcinoma. Postoperative pathology consultation established a diagnosis of stage IIIC primary peritoneal malignancy. She received three chemotherapy treatments before being admitted again.

Planning around adhesions and other medical conditions

The subsequent operation presented additional risks. Multiple previous abdominal operations had left extensive, dense adhesions and distorted anatomy in the pelvis and abdomen. The patient also had hypertension, heart valve regurgitation, a renal hamartoma, a liver haemangioma and gallbladder polyps. The hospital said these factors created a high risk of major bleeding and injury to the bowel or ureters during surgery.

Specialists from gynaecology, general surgery, anaesthesiology and imaging jointly assessed her condition through a multidisciplinary team. They considered adhesions, bleeding and organ injury risks, then developed an individualised surgical plan and a perioperative management plan after repeated discussions.

On 21 September, the team led by Cen Yao performed abdominal and pelvic adhesiolysis, omentectomy, total hysterectomy and tumour debulking involving both adnexa. These were the procedures described in the hospital's account; the operative milestone was in September, while the hospital published the report in October.

Monitoring after surgery

The team followed the integrated multidisciplinary plan after the operation. It closely monitored vital signs, drainage and laboratory results, while taking measures to prevent infection, thrombosis and electrolyte disturbances during the perioperative period.

The hospital's reported outcome was stable vital signs, improving indicators and good recovery at that stage. The case documents a cross-border sequence from an initially uncertain malignancy to pathology-based diagnosis, chemotherapy and a further high-risk operation, with the patient's prior surgery and accompanying conditions shaping the treatment plan. The results described concern postoperative recovery, rather than an established long-term cancer outcome.
