Assessment of wound perfusion with near-infrared angiography: A prospective feasibility study.

OBJECTIVE: To assess the feasibility of quantitatively measuring skin perfusion before and after suture or staple skin closure of vertical laparotomies using indocyanine green (ICG) uptake with near-infrared angiography. METHODS: This was a prospective, non-randomized feasibility study of patients undergoing surgery with a gynecologic oncology service from 2/2018-8/2019. Feasibility was defined as the ability to quantitatively measure ICG uptake adjacent to the wound at the time of skin closure in ≥ 80% of patients. Patients were assigned suture or staple skin closure in a sequential, non-randomized fashion. Skin perfusion was recorded using a near-infrared imaging system after ICG injection and measured by video analysis at predefined points before and after skin closure. Clinicodemographic, pre- and intraoperative details, and surgical secondary events were recorded. RESULTS: Of 20 participants, 10 were assigned staple closure and 10 suture closure. Two patients (10%) achieved objective quantification of ICG fluorescence before and after laparotomy closure, failing the predefined feasibility threshold of ≥ 80%. Reasons for failed quantification included overexposure (12), insufficient ICG signal uptake (6), and insufficient video quality (2). Near-infrared angiography wound perfusion was subjectively appreciated intraoperatively in 85% (17/20) of patients before and after wound closure. CONCLUSIONS: Objective assessment of laparotomy skin closure with near-infrared angiography-measured perfusion did not meet the pre-specified feasibility threshold. Adjustments to the protocol to minimize overexposure may be warranted. The ability to subjectively appreciate ICG perfusion with near-infrared angiography suggests a possible role for near-infrared angiography in the real-time intraoperative assessment of wound perfusion, particularly in high-risk patients.

Patient-reported benefit from proposed interventions to reduce financial toxicity during cancer treatment.

INTRODUCTION: Financial toxicity is common and pervasive among cancer patients. Research suggests that gynecologic cancer patients experiencing financial toxicity are at increased risk for engaging in harmful cost-coping strategies, including delaying/skipping treatment because of costs, or forsaking basic needs to pay medical bills. However, little is known about patients' preferences for interventions to address financial toxicity. METHODS: Cross-sectional surveys to assess financial toxicity [Comprehensive Score for Financial Toxicity (COST)], cost-coping strategies, and preferences for intervention were conducted in a gynecologic cancer clinic waiting room. Associations with cost-coping were determined using multivariate modeling. Unadjusted odds ratios (ORs) explored associations between financial toxicity and intervention preferences. RESULTS: Among 89 respondents, median COST score was 31.9 (IQR: 21-38); 35% (N = 30) scored < 26, indicating they were experiencing financial toxicity. Financial toxicity was significantly associated with cost-coping (adjusted OR = 3.32 95% CI: 1.08, 14.34). Intervention preferences included access to transportation vouchers (38%), understanding treatment costs up-front (35%), minimizing wait times (33%), access to free food at appointments (25%), and assistance with minimizing/eliminating insurance deductibles (23%). In unadjusted analyses, respondents experiencing financial toxicity were more likely to select transportation assistance (OR = 2.67, 95% CI: 1.04, 6.90), assistance with co-pays (OR = 9.17, 95% CI: 2.60, 32.26), and assistance with deductibles (OR = 12.20, 95% CI: 3.47, 43.48), than respondents not experiencing financial toxicity. CONCLUSIONS: Our findings confirm the presence of financial toxicity in gynecologic cancer patients, describe how patients attempt to cope with financial hardship, and provide insight into patients' needs for targeted interventions to mitigate the harm of financial toxicity.

Non-exenterative surgical management of recurrent endometrial carcinoma.

OBJECTIVE: To examine the role of non-exenterative secondary cytoreductive surgery (SCS) compared with non-surgical treatments and identify predictors of improved survival for patients with recurrent endometrial cancer (EC). METHODS: All patients undergoing primary surgical management for EC 1/1/2009-12/31/2017 who subsequently developed recurrence were retrospectively identified. Survival was determined from date of diagnosis of first recurrence to last follow-up and estimated using Kaplan-Meier method. Differences in survival were analyzed using Log-rank and Wald tests, based on Cox Proportional Hazards model. RESULTS: Among 376 patients with recurrent EC, median time to recurrence was 14.3 months (range, 0.2-102.2), post-recurrence median survival 29 months, median follow-up 29.2 months (range, 0-116). Sixty-one patients (16.2%) received SCS, 257 (68.4%) medical management (MM) (chemotherapy and/or radiation therapy), 32 (8.5%) hormonal therapy, 26 (6.9%) no further therapy. Patients selected for SCS were younger, had more endometrioid histology, more stage I disease at initial diagnosis, no residual disease after primary surgery, longer interval to first recurrence or progression, and the longest OS (57.6 months) (95% CI, 33.3-not reached). On multivariate analysis SCS was an independent predictor of improved survival. Among the 61 SCS patients, age < 70 at time of initial diagnosis, and endometrioid histology, were associated with improved post-relapse survival univariately (p = 0.008, 0.03, respectively). CONCLUSIONS: While MM was the most common treatment for first recurrence of EC, patients selected for surgery demonstrated the greatest survival benefit even after controlling for tumor size, site, histology, stage, time to recurrence. Careful patient selection and favorable tumor factors likely play a major role in improved outcomes. Surgical management should be considered whenever feasible in medically eligible patients, with additional consideration given to our suggested criteria.

Incidence of pelvic lymph node metastasis using modern FIGO staging and sentinel lymph node mapping with ultrastaging in surgically staged patients with endometrioid and serous endometrial carcinoma.

OBJECTIVE: We report the incidence of occult nodal metastasis in patients who underwent primary surgical staging for apparent early endometrioid or serous endometrial cancer with bilateral SLN mapping and enhanced pathology. Occult ovarian metastasis rates were also reported. METHODS: Patients with clinical stage I serous or endometrioid endometrial cancer who underwent primary staging surgery with successful bilateral SLN mapping from 1/2005-12/2018 were retrospectively evaluated. Rates of isolated tumor cells (ITCs), micro- and macrometastatic nodal disease, and occult ovarian involvement were reported. RESULTS: Of 1044 patients, 959 had endometrioid and 85 serous carcinoma. There were no positive SLNs among 510 patients with noninvasive FIGO grade 1/2 endometrioid carcinoma and < 1%ITCs. Grade 1: 4.5%(9/202) with inner-half and 10%(6/62) with outer-half myoinvasion had positive SLNs. Grade 2: rates were 4%(3/76) and 20%(8/41), respectively. Grade 3: 5%(1/20) with noninvasive, 3%(1/31) with inner-half, and 24%(4/17) with outer-half myoinvasion had positive SLNs. ITC incidence increased with depth of myoinvasion-25% of deeply invasive grade 1/2 and 18% of deeply invasive grade 3 tumors. Four (10%) of 41 patients with noninvasive serous endometrial carcinoma had ITCs or positive SLNs. There were no occult ovarian metastases with grades 1/2 disease, 2/68 (3%) with grade 3 disease, and 2/85 (2%) with serous endometrial carcinoma. CONCLUSION: Ultrastaging SLNs may be unwarranted in low-grade noninvasive endometrioid cancer but valuable in noninvasive serous carcinoma. Occult ovarian metastasis is uncommon in early endometrial carcinoma and occurs in 2-3% of high-risk histologies. Further research is needed to determine ITC significance, particularly with regard to adjuvant treatment.
