Case Report: Multidisciplinary approach for complete resection of primary advanced low-grade serous ovarian carcinoma involving the iliac vessels and paraspinal region.

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
Background: Low-grade serous ovarian carcinoma (LGSC) is characterized by indolent progression and relative resistance to cytotoxic chemotherapy, making complete cytoreduction the key prognostic determinant. However, extra-pelvic invasion presents significant surgical and functional challenges requiring coordinated multidisciplinary management. Case presentation: A 62-year-old woman with FIGO stage IVB LGSC presented with right inguinal swelling infiltrating the femoral vein and abdominal wall. MRI and PET-CT revealed bilateral ovarian tumors and multiple lymph node metastases. A multidisciplinary operation involving gynecologic, orthopedic, plastic, and gastrointestinal surgeons was conducted. The procedures included total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, pelvic and para-aortic lymphadenectomy, en bloc resection of the right inguinal lesion, femoral vein repair, and anterolateral thigh flap reconstruction. Complete resection (R0) was achieved. Postoperative recovery was favorable, with transient leg edema resolving within 4 months. The patient remains disease-free at 13 months after surgery. Discussion: Strategic multidisciplinary collaboration enabled complete resection and functional preservation in this chemotherapy-resistant LGSC case. We propose the "Four Surgical Limits" framework-anatomical, oncological, functional, and interdisciplinary-as a structured concept guiding operative decision-making beyond conventional boundaries. Conclusion: Multidisciplinary collaboration can overcome traditional surgical and oncologic barriers, achieving both radicality and quality-of-life preservation in advanced LGSC.
