Analysis of outcomes of microinvasive adenocarcinoma of the uterine cervix by treatment type

OBJECTIVE: To estimate the risk of metastatic disease in microinvasive adenocarcinoma of the cervix in a large cohort. METHODS: Thirty-six cases were identified from the Mayo Clinic health information database, and 30 cases were identified using the University of Southern California gynecologic oncology patient database. Histopathology was reviewed by a single pathologist at each institution to confirm histologic subtype and grade of tumor, depth of invasion, linear extent of the tumor, the presence or absence of lymphovascular space invasion, margin status, parametrial involvement, and the presence of nodal metastasis. RESULTS: Fifty-two patients had stage IA1 cancers and 14 had stage IA2 cancers. Therapy ranged from cold knife conization to radical hysterectomy with lymphadenectomy. No parametrial involvement was noted in any of the patients who underwent parametrial resection. One patient with stage IA1 cancer had micrometastasis to a pelvic lymph node. No recurrences were noted with an average follow-up of 80 months. CONCLUSION: The management of microinvasive adenocarcinoma remains controversial, and radical therapy is applied more frequently to microinvasive adenocarcinoma than microinvasive squamous cell carcinoma of the cervix. The risk of extracervical disease is low and the risk of recurrence is not affected by the radicality of resection. Our data suggest that microinvasive adenocarcinoma is amenable to treatment with nonradical surgery. LEVEL OF EVIDENCE: III

Time interval between endometrial biopsy and surgical staging for type I endometrial cancer: association between tumor characteristics and survival outcome.

OBJECTIVE: To examine whether wait time between endometrial biopsy and surgical staging correlates with tumor characteristics and affects survival outcomes in patients with type I endometrial cancer. METHODS: A retrospective study was conducted to examine patients with grade 1 and 2 endometrioid adenocarcinoma diagnosed by preoperative endometrial biopsy who subsequently underwent hysterectomy-based surgical staging between 2000 and 2013. Patients who received neoadjuvant chemotherapy or hormonal treatment were excluded. Time interval and grade change between endometrial biopsy and hysterectomy were correlated to demographics and survival outcomes. RESULTS: Median wait time was 57 days (range 1–177 days) among 435 patients. Upgrading of the tumor to grade 3 in the hysterectomy specimen was seen in 4.7% of 321 tumors classified as grade 1 and 18.4% of 114 tumors classified as grade 2 on the endometrial biopsy, respectively. Wait time was not associated with grade change (P>.05). Controlling for age, ethnicity, body habitus, medical comorbidities, CA 125 level, and stage, multivariable analysis revealed that wait time was not associated with survival outcomes (5-year overall survival rates, wait time 1–14, 15–42, 43–84, and 85 days or more; 62.5%, 93.6%, 95.2%, and 100%, respectively, P>.05); however, grade 1 to 3 on the hysterectomy specimen remained as an independent prognosticator associated with decreased survival (5-year overall survival rates, grade 1 to 3 compared with grade change 1 to 1, 82.1% compared with 98.5%, P=.01). Among grade 1 preoperative biopsies, grade 1 to 3 was significantly associated with nonobesity (P=.039) and advanced stage (P=.019). CONCLUSION: Wait time for surgical staging was not associated with decreased survival outcome in patients with type I endometrial cancer. LEVEL OF EVIDENCE: II

Significance of perioperative infection in survival of patients with ovarian cancer.

Objectives Perioperative infectious diseases comprise some of the most common causes of surgical mortality in women with ovarian cancer. This study was aimed to evaluate the significance of perioperative infections in survival of patients with ovarian cancer. Methods Patients who underwent primary cytoreductive surgery were included in the analysis (n = 276). The enumeration and speciation of pathogens, antimicrobial agents used, and sensitivity assay results were culled from medical records and correlated to clinicopathologic demographics and survival outcomes. Perioperative infection was determined as a positive microbiology result obtained within a 6-week postoperative period. Results The incidence of perioperative infection was 15.9% (common sites: urinary tract, 57.3%, and surgical wound, 21.4%). Commonly isolated pathogens were Enterococcus species (22.4%) and Escherichia coli (19.4%) in urinary tract infection, and Bacteroides fragilis, E. coli, and Klebsiella pneumoniae (all, 16%) in surgical wound infection. Imipenem represents one of the least resistant antimicrobial agents commonly seen in urinary tract and surgical wound infections in our institution. Perioperative infection was associated with diabetes, serous histology, lymph node metastasis, bowel resection, decreased bicarbonate, and elevated serum urea nitrogen in multivariate analysis. Perioperative infections were associated with increased surgical mortality, delay in chemotherapy treatment, decreased chemotherapy response, shorter progression-free survival (median time, 8.4 vs 17.6 months; P < 0.001), and decreased overall survival (29.0 vs 51.8 months; P = 0.011). Multivariate analysis showed that perioperative infections other than urinary tract infection remained a significant risk factor for decreased survival (progression-free survival, P = 0.02; and overall survival, P = 0.019). Conclusion Perioperative infectious disease comprises an independent risk factor for survival of patients with ovarian cancer.

Fetoscopic Laser Photocoagulation of Feeding Vessels to a Large Placental Chorioangioma following Fetal Deterioration after Amnioreduction

Large placental chorioangiomas (>4 cm) can precipitate severe polyhydramnios, fetal anemia, growth restriction, high-output cardiac failure, hydrops, and fetal demise. We report a case of a large chorioangioma that was treated in a stepwise fashion with amnioreduction to ameliorate maternal discomfort, followed by fetoscopic laser ablation of the feeding vessels after rapid evolution of heart failure. Although amnioreduction was helpful in improving maternal symptoms, we suspect that the drop in intrauterine pressure from the amniotic fluid decompression may have resulted in increased tumor perfusion, thereby promoting fetal deterioration due to a ‘steal’ phenomenon. Close scrutiny of the fetal status via ultrasound is required, particularly if amnioreduction is necessary, and definitive treatment should be considered once early signs of heart failure develop. Fetoscopic laser ablation of the feeding vessels is a feasible definitive treatment of a large chorioangioma in cases in which perfusion of the tumor is via a superficial nonterminus umbilical artery. Future reports should describe the anatomy of the blood supply to the chorioangioma, in the hopes that further guidelines for surgical candidacy may be established.

Abdominal aortic resection and Y-graft placement to achieve complete cytoreduction in stage IIIc ovarian carcinoma.

BACKGROUND: Major vascular resection with reconstruction in patients with gynecologic malignancy is rarely performed and infrequently reported. CASE: A 40-year-old woman undergoing surgery for stage IIIc ovarian papillary serous adenocarcinoma was left with a 7-cm aortic metastasis not separable from the infrarenal abdominal aorta. An aortic resection with prosthetic graft placement was performed to achieve complete tumor resection. She remains disease-free in excess of 10 years with no evidence of graft complication. CONCLUSION: Major vascular reconstructive procedures for the management of malignancy need not be precluded in properly selected circumstances.

Novel application of a fecal management system for vaginal use in radiotherapy-associated rectovaginal fistula.

While highly effective for treating certain gynecologic malignancies, radiotherapy carries known risks, including fistula formation. We report a 75-year-old female with advanced cervical carcinoma who was provided a vaginally placed fecal management system after developing a rectovaginal fistula following primary treatment with chemoradiation. This report presents and discusses a novel method to palliate symptomatic RVFs in advanced-stage cancer.

Significance of Monocyte Counts at Recurrence on Survival Outcome of Women With Endometrial Cancer.

Objective Tumor-associated macrophages (TAMs) are known to have adverse effects on the survival of women with endometrial cancer. Because monocytes function as progenitors of macrophages, this study examined the association between monocyte count at the first recurrence/progression of endometrial cancer and survival time after recurrence/progression (SAR). Methods This is a retrospective study evaluating 141 consecutive cases of recurrent endometrial cancer after surgical staging (n = 114) and progression after nonsurgical management (n = 27). Complete blood cell counts with cell differentiation at the time of the first recurrence/progression were correlated to SAR. Results Median time of SAR was 7.8 months, and there were 97 (68.8%) patients who died from endometrial cancer with 1-, 2-, and 5-year SAR rates being 51.0%, 32.9%, and 14.2%, respectively. Median monocyte counts at recurrence/progression were 0.5 × 109/L. The strongest correlation to monocyte counts was seen in neutrophil counts (r = 0.57, P < 0.01) followed by platelet counts (r = 0.43, P < 0.01). An elevated monocyte count at recurrence/progression was significantly associated with decreased SAR (hazard ratio per unit, 3.97; 95% confidence interval, 2.00–7.90; P < 0.01). On multivariate analysis controlling for patient demographics, complete blood cell counts, tumor factors, and treatment types for recurrent/progressed disease, higher monocyte counts at recurrence/progression remained an independent predictor for decreased SAR (hazard ratio per unit, 3.12; 95% confidence interval, 1.52–6.67; P < 0.01). Conclusions Our study demonstrated that the increased monocyte counts at recurrence/progression may be a useful biomarker for predicting decreased survival outcome of women with endometrial cancer.
