Objectives: To evaluate the incidence and risk factors for lymphedema associated with surgery for gynecologic malignancies on GOG study 244.Methods: Women undergoing a lymph node dissection for endometrial, cervical, or vulvar cancer were eligible for enrollment. Leg volume was calculated from measurements at 10-cm intervals starting 10 cm above the bottom of the heel to the inguinal crease. Measurements were obtained preoperatively and postoperatively at 4-6 weeks, and at 3-, 6-, 9-, 12-, 18-, and 24months. Lymphedema was defined as a limb volume change (LVC) ≥10% from baseline and categorized as mild: 10-19% LVC; moderate: 20-40% LVC; or severe: >40% LVC. Risk factors associated with lymphedema were also analyzed.
Results:Of 1054 women enrolled on study, 140 were inevaluable due to inadequate measurements or eligibility criteria. This left 734 endometrial, 138 cervical, and 42 vulvar patients evaluable for LVC assessment. Median age was 61 years (range, 28-91) in the endometrial, 44 years (range, 25-83) in the cervical, and 58 years (range, 35-88) in the vulvar group. The incidence of LVC ≥10% was 34% (n=247), 35% (n=48), and 43% (n=18), respectively. The peak incidence of lymphedema was at the 4-6 week assessment. Logistic regression analysis showed a Carlson et al.
The Gynecologic Oncology Group performed a Phase II study to determine the response rate of pyrazoloacridine (PZA) in patients with platinum-resistant ovarian cancer. PZA was administered at a dose of 750 mg/m2 intravenously over 3 hours every 3 weeks. Among 24 evaluable patients, there was 1 (4.2%) complete and 1 (4.2%) partial response. The major toxicities were hematologic. With the dose and schedule used, PZA had only modest activity in this population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
