Objective:
Minimally invasive radical hysterectomy has a worse prognosis than open surgery, but the reasons for the poor prognosis remain unclear. Tumor spillage occurs when the tumor is exposed to the surgical field and has been suggested to be related to a poor prognosis. This study aimed to compare the prognostic value of tumor spillage in laparoscopic radical hysterectomy and evaluate whether tumor spillage prevention improves oncological safety.
Methods:
We compared the prognosis of patients who underwent laparoscopic radical hysterectomy between December 2014 and November 2021 with or without tumor spillage prevention, including surgeries without prevention and those with failed prevention.Prevention consisted of vaginal cuff formation or closure of the vaginal canal with clips to prevent tumor exposure at the time of colpotomy. The primary endpoint was disease-free survival, which was adjusted using propensity scores to compare patients.
Results:
In total, 165 patients received tumor spillage prevention, and 61 did not or failed to receive such prevention. The median follow-up was 4.4 years. Patients who did not undergo prevention or failed prevention had significantly shorter disease-free survival than those who did (hazard ratio [HR]=3.54; 95% confidence interval [CI]=1.23–10.23). The same trend was observed after adjusting for propensity score matching. Patients who did not or failed to receive prevention were more likely to experience local recurrence (HR=4.01; 95% CI=1.13–14.24).
Conclusion
Tumor spillage prevention was associated with longer disease-free survival in laparoscopic radical hysterectomy.

Objective:
In advanced ovarian cancer, achieving R0 resection is a critical strategy for improving prognosis. However, even with R0 resection, the prognosis of patients with a high tumor burden remains poor. This study aimed to assess whether the introduction of poly(ADP-ribose) polymerase inhibitors (PARPi) has enhanced outcomes in such cases.
Methods:
We retrospectively analyzed patients with International Federation of Gynecology and Obstetrics (FIGO) stage III–IV ovarian cancer treated between January 2015 and December 2021. Patients were classified into Group A (pre-PARPi introduction) and Group B (post-PARPi introduction). Complete macroscopic resection was defined as R0. Progressionfree survival (PFS), stratified by the Aletti Surgical Complexity Score (Aletti_SCS), was the primary endpoint and was evaluated using Cox regression models.
Results:
A total of 434 patients were included. In Group A, among those who achieved R0, the median PFS was 23.5 months for patients with high Aletti_SCS (95% confidence interval [CI]=14–30) and not reached for those with low Aletti_SCS (95% CI=30–not reached; adjusted hazard ratio [HR]=0.36, 95% CI=0.20–0.62). In Group B, the median PFS was not reached in both patients with high Aletti_SCS (95% CI=not reached–not reached) and low Aletti_SCS (95% CI=22–not reached; adjusted HR=4.98, 95% CI=1.14–21.78).
Conclusion
Following the introduction of PARPi, there was a trend toward improved PFS in patients with a higher Aletti_SCS who underwent R0 resection. These findings suggest that R0 resection may improve prognosis even in cases with a high tumor burden in the PARPi era.

Objective:
To describe anatomic patterns of the superficial uterine vein (sUV) and assess their association with aspects of the dissection procedure of the anterior layer of the vesicouterine ligament (aVUL) by retrospectively reviewing surgical videos.
Methods:
We analyzed patients who underwent laparoscopic radical hysterectomy for early-stage cervical cancer from 2014 to 2019. The primary endpoint was the time required for aVUL dissection. Multiple linear regression analyses were performed to identify factors influencing the time required for aVUL dissection.
Results:
Fifty-three Japanese patients were included. Two sUV configurations were observed:type 1 (the vein ran ventral to the ureter along the uterine artery) and type 2 (the vein did not run along the usual ventral course; it ran dorsal to the ureter or was absent). Approximately 30% of the sUVs were type 2. The total time for dissection of both sides of the aVUL was significantly shorter for type 2 sUVs than for type 1 sUVs. The number of hemostatic interventions during dissection of each side of the aVUL was significantly lower for type 2 sUVs than for type 1 sUVs. In the multivariate analysis, the sUV configuration was the factor significantly influencing the duration of aVUL dissection on each side (right side: β=−143.4;left side, β=−160.4).
Conclusion
We demonstrated that the sUV had 2 types of courses, ventral and others, and its course affected the time required for dissection and the number of hemostatic interventions.Our results provide information supportive of improved radical hysterectomy outcomes.

Objective:
The combination of cancer and hypercoagulable states is often called Trousseau syndrome. In particular, cerebral infarction caused by Trousseau syndrome is reported to have a poor prognosis. In gynecology, there are many reports of ovarian cancer and a few of uterine cancer. Since there has been no comprehensive report of Trousseau syndrome in cervical cancer, we aimed to summarize Trousseau syndrome in cervical cancer.
Methods:
Cerebral infarction caused by cancer-related arterial thrombosis was defined as Trousseau syndrome. Patients with cervical cancer diagnosed at our hospital between January 2014 and December 2021 were retrospectively reviewed using the hospital’s medical records.
Results:
A total of 1,432 patients were included in the study. Trousseau syndrome occurred in 6 patients (0.4%). The mean age of patients with Trousseau syndrome was 63 years (range:53–78 years). Of the 6 patients who developed Trousseau’s syndrome, 4 patients had it before or during initial treatment, and 2 during recurrent/relapsed disease treatment. The 4 patients who developed the syndrome before or during initial treatment had advanced disease: 1 in stage IIIC and 3 in stage IVB. In all cases, the disease was associated with progressive distant metastasis. The median survival time from the onset of Trousseau syndrome was 1 month (range: 0–6 months).
Conclusion
Cervical cancer causes Trousseau syndrome in cases of advanced disease with a short time between the onset of the syndrome and mortality.
