Metastatic extent-specific prognosis of women with stage IVB cervical cancer: multiple versus single distant organ involvement.

PURPOSE: Despite the heterogeneity of anatomical sites that metastases may affect, within the current cancer staging schematic, stage IVB encompasses all distant metastasis. This study examined survival outcomes based on the extent of distant organ metastasis in stage IVB cervical cancer. METHODS: This retrospective cohort study utilized the National Cancer Institute's Surveillance, Epidemiology, and End Result Program from 2010 to 2018. The study population included 1772 women with stage IVB cervical cancer who had tumor metastasis to one or more of the following four organs: bone, brain, liver, or lung. Overall survival was assessed based on the metastatic extent in multivariable analysis. RESULTS: The most common metastatic site was lung (68.3%) followed by bone (35.2%), liver (30.0%), and brain (1.2%). Multiple organ metastases were seen in 26.5% of study population, with lung / liver metastases being the most frequent combination pattern (9.6%) followed by lung / bone (9.4%), and lung / bone / liver (6.4%). A total of 1442 (81.4%) deaths occurred during the follow-up. The cohort-level median overall survival was 7 months, ranging from 3 months in all four organ metastases to 11 months in bone metastasis alone when stratified (absolute difference 8 months, P < 0.001). Multiple organ metastases were independently associated with nearly 50% increased all-cause mortality risk compared to single organ metastasis (adjusted-hazard ratio 1.51, 95% CI 1.34-1.70). CONCLUSION: Survival outcomes in those with stage IVB cervical cancer with distant organ involvement can vary based on the extent of metastasis. Incorporation of single versus multiple distant organ metastasis into the cancer staging schema may be valuable (IVB1 versus IVB2).

Trends and characteristics of ovarian conservation at hysterectomy for young women with cervical cancer.

OBJECTIVE: The association between early surgical menopause and increased mortality has been well demonstrated. Prior studies have also demonstrated that ovarian conservation is not associated with worse oncologic outcomes in early-stage cervical cancer. This study examined the contemporary trends and characteristics of ovarian conservation at time of hysterectomy in young women with cervical cancer. METHODS: This is a retrospective cohort study examining the National Inpatient Sample. The study population was 4900 women aged ≤50 years with cervical cancer who had hysterectomy-based surgical treatment from 10/2015 to 12/2018. The exposure allocation was the adnexal procedure status (ovarian conservation versus oophorectomy). The main outcome measures were temporal trends of ovarian conservation over time and per patient age. Multivariable binary logistic regression model was fitted to identify independent characteristics associated with ovarian conservation. A classification-tree was constructed by recursive partitioning analysis to examine the utilization patterns of ovarian conservation. RESULTS: A total of 2,940 (60.0%) women underwent ovarian conservation at hysterectomy. Ovarian conservation rates remained stable until age 37 years, ranging from 82.5% to 77.9% (P = 0.502), after which time the rate sharply and significantly decreased by 7.4% (95% confidence interval 5.4-9.3, P < 0.001) in one-year age increments from 77.9% at age 37 years to 28.7% at age 50 years. The rate of ovarian conservation increased from 54.7% in Q4/2015 to 64.4% in Q4/2018 (P = 0.002). In multivariable analysis, recent surgery remained an independent factor for ovarian conservation (adjusted-odds ratio per year-quarter 1.04, 95% confidence interval 1.03-1.06). A classification-tree model identified 24 unique patterns of ovarian conservation based on patient factor (age, race/ethnicity, primary expected payer, and year of surgery), surgical factor (minimally invasive hysterectomy), and facility factor (hospital bed capacity and region), ranging from <20% to 90% (absolute percentage difference, >80%). CONCLUSION: Increasing rates of ovarian conservation at the time of hysterectomy in women undergoing surgical management of cervical cancer is encouraging; however, the marked decrease noted in patients in their mid-30s as well as substantial variability in ovarian conservation based on patient, surgical, and hospital factors are striking and warrant further consideration in clinical practice guidelines.

Outpatient ocular brachytherapy: The USC Experience.

PURPOSE: Ocular brachytherapy is a standard-of-care surgical procedure for globe salvage in the treatment of uveal melanoma. The procedure involves the placement and subsequent removal of a radioactive plaque several days later. At many locations, patients are admitted on an inpatient basis until plaque removal due to radiation safety concerns. However, patients may be discharged to home after plaque insertion, and subsequently return to the medical facility for plaque removal. This study aimed to evaluate the safety and systematic financial benefit of the outpatient ocular brachytherapy program at "?>the University of Southern California (USC) Roski Eye Institute for 30 years. METHODS AND MATERIALS: A single-institution retrospective record review was performed on all 275 patients who underwent brachytherapy for ocular tumors between January 1, 1989 and December 31, 2019 to assess for occurrences of reportable radiation and/or patients safety events. The treatment protocols at our institution are described. Data on hospital-adjusted expenses per inpatient day from the American Hospital Association's 2018 Annual Survey were used as a proxy for costs to patients and the health care system to perform a cost-benefit analysis comparing outpatient versus inpatient brachytherapy. RESULTS: Of the 275 plaque procedures over a 30-year period that were reviewed, there were no internally or externally reportable patient or radiation safety events. There were no adverse events related to patient transportation to the hospital, the patient not returning for plaque removal, operative issues in removing the plaque on time due to cancelled or delayed cases, or loss of radioactive material. Additionally, our cost-benefit analysis estimates that outpatient brachytherapy reduced costs for USC's patients in 2018 by an average of $24,722 per patient treated with ocular brachytherapy. CONCLUSIONS: With appropriate measures, outpatient ocular brachytherapy allows patients to safely return home with the added benefit of decreased financial burden for both patients and the broader health care system.
