The baseline recurrence risk of patients with intermediate-risk cervical cancer.
Objective:This study aimed to investigate the prognosis of patients with intermediate-risk cervical cancer and to evaluate the necessity of adjuvant therapy.Methods:We conducted a retrospective chart review of patients with stage IB-II cervical cancer who underwent type III radical hysterectomy with pelvic lymphadenectomy between 2008 and 2017. In our institution, radical hysterectomy is performed as an open surgery and not as a minimally invasive surgery, and adjuvant therapy is not administered to patients with intermediate-risk cervical cancer. The intermediate-risk group included patients with 2 or more of the following factors: tumor size >4 cm, stromal invasion >1/2, and lymphovascular stromal invasion. Intermediaterisk patients with squamous cell carcinoma were included in the I-SCC group, whereas those with endocervical adenocarcinoma, usual type, or adenosquamous carcinoma were included in the I-Adeno group.Results:There were 34 and 18 patients in the I-SCC and I-Adeno groups, respectively. The 5-year recurrence-free survival (RFS) and overall survival rates in the I-SCC group were 90.5% (95% confidence interval [CI], 85.3-95.7%) and 100% (95% CI, 100%), respectively, whereas those in the I-Adeno group were 54.9% (95% CI, 42.0-67.9%) and 76.1% (95% CI, 63.7-88.4%), respectively. Multivariate analysis revealed that endocervical adenocarcinoma, usual type, or adenosquamous carcinoma, and tumor size >4 cm had worse RFS.Conclusion:The I-SCC group had good prognosis without adjuvant therapy; therefore, adjuvant therapy may be omitted in these patients. In contrast, the I-Adeno group had poor prognosis without adjuvant therapy; therefore, adjuvant therapy should be considered in their treatment

Spontaneous ureteral rupture during concurrent chemoradiotherapy in a woman with uterine cervical cancer
Spontaneous rupture of the renal pelvis and ureter is associated with obstruction of the urinary collecting system, but is rarely caused by tumors. We describe our experience with a patient who had uterine cervical cancer with mild hydroureter in whom spontaneous ureteral rupture occurred during concurrent chemoradiotherapy. The patient was a 66-year-old woman with stage IIIB uterine cervical cancer and mild hydroureter who received concurrent chemoradiotherapy. The patient felt uncontrolled right-side abdominal pain caused by ureteral rupture after she was given hydration and an intravenous bolus injection of furosemide during the first week of chemoradiotherapy. Contrast-enhanced computed tomography was more useful than ultrasonography for diagnosis of the ureteral rupture. The ureteral rupture in our patient was attributed to a rapid rise in the pressure of the urinary collecting system caused by hydration and the bolus injection of furosemide. Placement of a double-J stent before starting concurrent chemoradiotherapy may help to prevent ureteral rupture in patients who have uterine cervical cancer with mild hydroureter

Prognostic impact of intraoperative peritoneal cytology in interval debulking surgery for pelvic high‐grade serous carcinoma
Abstract Background and Objectives The aim of this study was to determine whether peritoneal washing cytology (PWC) during interval debulking surgery (IDS) could predict the prognosis of patients with pelvic high‐grade serous carcinoma (HGSC) achieving R0 status. Methods Between January 2007 and May 2018, 110 patients with ovarian/tubal/primary peritoneal HGSC received platinum‐based neo‐adjuvant chemotherapy, followed by IDS at National Cancer Center Hospital, Japan. All the patients achieved R0 debulking status, defined as no macroscopic residual tumor in the peritoneal cavity at the completion of IDS. PWC was performed before debulking during IDS. The survival outcomes were compared between the PWC‐positive and PWC‐negative groups. Results The median progression free survival (PFS) for the entire cohort was 17 months (range, 5‐133 months). The median PFS for the PWC‐positive group was significantly shorter than that of the PWC‐negative group (16 vs 19 months, HR 2.04, 95% CI 1.22‐3.41, P‐value < 0.01). Increased risk of progression was observed on both univariate and multivariate analyses, including age and FIGO stage (HR 2.28; 95% CI 1.35‐3.84, P < 0.01). Conclusions The positive PWC during IDS was found to predict earlier disease recurrence in patients with pelvic HGSC achieving R0 status. As performing PWC during IDS becomes standard practice, prospective validation should be conducted in the future
