Prophylactic Negative Pressure Wound Therapy After Laparotomy for Gynecologic Surgery: A Randomized Controlled Trial.

OBJECTIVE: To estimate the effectiveness of prophylactic negative pressure wound therapy in patients undergoing laparotomy for gynecologic surgery. METHODS: We conducted a randomized controlled trial. Eligible, consenting patients, regardless of body mass index (BMI), who were undergoing laparotomy for presumed gynecologic malignancy were randomly allocated to standard gauze or negative pressure wound therapy. Patients with BMIs of 40 or greater and benign disease also were eligible. Randomization, stratified by BMI, occurred after skin closure. The primary outcome was wound complication within 30 (±5) days of surgery. A sample size of 343 per group (N=686) was planned. RESULTS: From March 1, 2016, to August 20, 2019, we identified 663 potential patients; 289 were randomized to negative pressure wound therapy (254 evaluable participants) and 294 to standard gauze (251 evaluable participants), for a total of 505 evaluable patients. The median age of the entire cohort was 61 years (range 20-87). Four hundred ninety-five patients (98%) underwent laparotomy for malignancy. The trial was eventually stopped for futility after an interim analysis of 444 patients. The rate of wound complications was 17.3% in the negative pressure wound therapy (NPWT) group and 16.3% in the gauze group, absolute risk difference 1% (90% CI -4.5 to 6.5%; P=.77). Adjusted odds ratio controlling for estimated blood loss and diabetes was 0.99 (90% CI 0.62-1.60). Skin blistering occurred in 33 patients (13%) in the NPWT group and in three patients (1.2%) in the gauze group (P\u3c.001). CONCLUSION: Negative pressure wound therapy after laparotomy for gynecologic surgery did not lower the wound complication rate but did increase skin blistering.

Olaparib tablets as maintenance therapy in patients with platinum-sensitive, relapsed ovarian cancer and a BRCA1/2 mutation (SOLO2/ENGOT-Ov21): a double-blind, randomised, placebo-controlled, phase 3 trial

Background Olaparib, a poly(ADP-ribose) polymerase (PARP) inhibitor, has previously shown efficacy in a phase 2 study when given in capsule formulation to all-comer patients with platinum-sensitive, relapsed high-grade serous ovarian cancer. We aimed to confirm these findings in patients with a BRCA1 or BRCA2 (BRCA1/2) mutation using a tablet formulation of olaparib. Methods This international, multicentre, double-blind, randomised, placebo-controlled, phase 3 trial evaluated olaparib tablet maintenance treatment in platinum-sensitive, relapsed ovarian cancer patients with a BRCA1/2 mutation who had received at least two lines of previous chemotherapy. Eligible patients were aged 18 years or older with an Eastern Cooperative Oncology Group performance status at baseline of 0\ue2\u80\u931 and histologically confirmed, relapsed, high-grade serous ovarian cancer or high-grade endometrioid cancer, including primary peritoneal or fallopian tube cancer. Patients were randomly assigned 2:1 to olaparib (300 mg in two 150 mg tablets, twice daily) or matching placebo tablets using an interactive voice and web response system. Randomisation was stratified by response to previous platinum chemotherapy (complete vs partial) and length of platinum-free interval (6\ue2\u80\u9312 months vs \ue2\u89\ua512 months) and treatment assignment was masked for patients, those giving the interventions, data collectors, and data analysers. The primary endpoint was investigator-assessed progression-free survival and we report the primary analysis from this ongoing study. The efficacy analyses were done on the intention-to-treat population; safety analyses included patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov, number NCT01874353, and is ongoing and no longer recruiting patients. Findings Between Sept 3, 2013, and Nov 21, 2014, we enrolled 295 eligible patients who were randomly assigned to receive olaparib (n=196) or placebo (n=99). One patient in the olaparib group was randomised in error and did not receive study treatment. Investigator-assessed median progression-free survival was significantly longer with olaparib (19\uc2\ub71 months [95% CI 16\uc2\ub73\ue2\u80\u9325\uc2\ub77]) than with placebo (5\uc2\ub75 months [5\uc2\ub72\ue2\u80\u935\uc2\ub78]; hazard ratio [HR] 0\uc2\ub730 [95% CI 0\uc2\ub722\ue2\u80\u930\uc2\ub741], p<0\uc2\ub70001). The most common adverse events of grade 3 or worse severity were anaemia (38 [19%] of 195 patients in the olaparib group vs two [2%] of 99 patients in the placebo group), fatigue or asthenia (eight [4%] vs two [2%]), and neutropenia (ten [5%] vs four [4%]). Serious adverse events were experienced by 35 (18%) patients in the olaparib group and eight (8%) patients in the placebo group. The most common in the olaparib group were anaemia (seven [4%] patients), abdominal pain (three [2%] patients), and intestinal obstruction (three [2%] patients). The most common in the placebo group were constipation (two [2%] patients) and intestinal obstruction (two [2%] patients). One (1%) patient in the olaparib group had a treatment-related adverse event (acute myeloid leukaemia) with an outcome of death. Interpretation Olaparib tablet maintenance treatment provided a significant progression-free survival improvement with no detrimental effect on quality of life in patients with platinum-sensitive, relapsed ovarian cancer and a BRCA1/2 mutation. Apart from anaemia, toxicities with olaparib were low grade and manageable. Funding AstraZeneca
