Long-term survival of a patient with colorectal cancer with peritoneal carcinomatosis and low completeness of cytoreduction score: A case report.
Article in World journal of gastrointestinal oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPeritoneal metastasis occurs in about 20% of patients with colorectal cancer (CRC) and is associated with a 5-year survival rate of only 6%. Cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy reportedly improves survival in selected patients. Achieving complete cytoreduction, indicated by a low completeness of cytoreduction (CCR) score, is a key factor in extending survival. Here, we present a case in which multimodal therapy yielded long-term survival in a patient, even though she had a CCR score of 3. CASE SUMMARY: A 61-year-old female with CRC and extensive peritoneal metastases presented with abdominal distention. Cytoreductive surgery was not completed due to the extent of the disease (CCR score: 3). The patient underwent palliative omentectomy, followed by hyperthermic intraperitoneal chemotherapy with mitomycin C, and early postoperative intraperitoneal chemotherapy. She subsequently received systemic chemotherapy, which was terminated after 19 cycles and two dose reductions due to side effects. She was in good health without distant metastases or peritoneal recurrence at the 6-year follow-up.
conclusionAggressive multimodal treatment may yield long-term survival and quality of life improvement in patients with advanced disease, even with high CCR scores.
