GOG 244 - The Lymphedema and Gynecologic cancer (LeG) study: The impact of lower-extremity lymphedema on quality of life, psychological adjustment, physical disability, and function.

OBJECTIVE: To assess quality of life (QOL) in patients who developed lower-extremity lymphedema (LLE) after radical gynecologic cancer surgery on prospective clinical trial GOG 244. METHODS: The prospective, national, cooperative group trial GOG-0244 determined the incidence of LLE and risk factors for LLE development, as well as associated impacts on QOL, in newly diagnosed patients undergoing surgery for endometrial, cervical, or vulvar cancer from 6/4/2012-11/17/2014. Patient-reported outcome (PRO) measures of QOL (by the Functional Assessment of Cancer Therapy [FACT]), body image, sexual and vaginal function, limb function, and cancer distress were recorded at baseline (within 14 days before surgery), and at 6, 12, 18, and 24 months after surgery. Assessments of LLE symptoms and disability were completed at the time of lower limb volume measurement. A linear mixed model was applied to examine the association of PROs/QOL with a Gynecologic Cancer Lymphedema Questionnaire (GCLQ) total score incremental change ≥4 (indicative of increased LLE symptoms) from baseline, a formal diagnosis of LLE (per the GCLQ), and limb volume change (LVC) ≥10%. RESULTS: In 768 evaluable patients, those with a GCLQ score change ≥4 from baseline had significantly worse QOL (p < 0.001), body image (p < 0.001), sexual and vaginal function (p < 0.001), limb function (p < 0.001), and cancer distress (p < 0.001). There were no significant differences in sexual activity rates between those with and without LLE symptoms. CONCLUSIONS: LLE is significantly detrimental to QOL, daily function, and body image. Clinical intervention trials to prevent and manage this chronic condition after gynecologic cancer surgery are needed.

GOG 244-The lymphedema and gynecologic cancer (LEG) study: Incidence and risk factors in newly diagnosed patients.

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 24- months. 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 decreased risk with advanced age (p = 0.0467). An exploratory analysis in the endometrial cohort showed an increased risk with a node count >8 (p = 0.033). CONCLUSIONS: For a gynecologic cancer, LVC decreased with age greater than 65, but increased with a lymph node count greater than 8 in the endometrial cohort. There was no association with radiation or other risk factors.

GOG 244 - The LymphEdema and Gynecologic cancer (LEG) study: The association between the gynecologic cancer lymphedema questionnaire (GCLQ) and lymphedema of the lower extremity (LLE).

OBJECTIVE: To explore whether patient-reported lymphedema-related symptoms, as measured by the Gynecologic Cancer Lymphedema Questionnaire (GCLQ), are associated with a patient-reported diagnosis of lymphedema of the lower extremity (LLE) and limb volume change (LVC) in patients who have undergone radical surgery, including lymphadenectomy, for endometrial, cervical, or vulvar cancer on Gynecologic Oncology Group (GOG) study 244. METHODS: Patients completed the baseline and at least one post-surgery GCLQ and LVC assessment. The 20-item GCLQ measures seven symptom clusters-aching, heaviness, infection-related, numbness, physical functioning, general swelling, and limb swelling. LLE was defined as a patient self-reported LLE diagnosis on the GCLQ. LVC was measured by volume calculations based on circumferential measurements. A linear mixed model was fitted for change in symptom cluster scores and GCLQ total score and adjusted for disease sites and assessment time. RESULTS: Of 987 eligible patients, 894 were evaluable (endometrial, 719; cervical, 136; vulvar, 39). Of these, 14% reported an LLE diagnosis (endometrial, 11%; cervical, 18%; vulvar, 38%). Significantly more patients diagnosed versus not diagnosed with LLE reported ≥4-point increase from baseline on the GCLQ total score (p < 0.001). Changes from baseline were significantly larger on all GCLQ symptom cluster scores in patients with LLE compared to those without LLE. An LVC increment of >10% was significantly associated with reported general swelling (p < 0.001), heaviness (p = 0.005), infection-related symptoms (p = 0.002), and physical function (p = 0.006). CONCLUSIONS: Patient-reported symptoms, as measured by the GCLQ, discerned those with and without a patient-reported LLE diagnosis and demonstrated predictive value. The GCLQ combined with LVC may enhance our ability to identify LLE.

Effects of the WRITE Symptoms Interventions on Symptoms and Quality of Life Among Patients With Recurrent Ovarian Cancers: An NRG Oncology/GOG Study (GOG-0259).

PURPOSE: GOG-259 was a 3-arm randomized controlled trial of two web-based symptom management interventions for patients with recurrent ovarian cancer. Primary aims were to compare the efficacy of the nurse-guided (Nurse-WRITE) and self-directed (SD-WRITE) interventions to Enhanced Usual Care (EUC) in improving symptoms (burden and controllability) and quality of life (QOL). METHODS: Patients with recurrent or persistent ovarian, fallopian, or primary peritoneal cancer with 3+ symptoms were eligible for the study. Participants completed baseline (BL) surveys (symptom burden and controllability and QOL) before random assignment. WRITE interventions lasted 8 weeks to develop symptom management plans for three target symptoms. All women received EUC: monthly online symptom assessment with provider reports; online resources; and every 2-week e-mails. Outcomes were evaluated at 8 and 12 weeks after BL. Repeated-measures modeling with linear contrasts evaluated group by time effects on symptom burden, controllability, and QOL, controlling for key covariates. RESULTS: Participants (N = 497) reported mean age of 59.3 ± 9.2 years. At BL, 84% were receiving chemotherapy and reported a mean of 14.2 ± 4.9 concurrent symptoms, most commonly fatigue, constipation, and peripheral neuropathy. Symptom burden and QOL improved significantly over time (P < .001) for all three groups. A group by time interaction (P < .001) for symptom controllability was noted whereby both WRITE intervention groups had similar improvements from BL to 8 and 12 weeks, whereas EUC did not improve over time. CONCLUSION: Both WRITE Intervention groups showed significantly greater improvements in symptom controllability from BL to 8 and BL to 12 weeks compared with EUC. There were no significant differences between Nurse-WRITE and SD-WRITE. SD-WRITE has potential as a scalable intervention for a future implementation study.

A phase II evaluation of weekly docetaxel in the treatment of recurrent or persistent endometrial carcinoma: a study by the Gynecologic Oncology Group.

OBJECTIVE: A phase II study was conducted to evaluate the anti-tumor activity and adverse effects of weekly docetaxel in patients with previously treated endometrial cancer. METHODS: Eligible patients were to have measurable disease with no more than one prior chemotherapy regimen. Docetaxel 36 mg/m(2) was administered intravenously over 1 h on days 1, 8 and 15. Cycles were repeated every 28 days until progression of disease or adverse effects prohibited further therapy. RESULTS: Twenty-seven patients were entered onto this study, of whom 26 were eligible and evaluable. All patients had received prior platinum with twenty (76.9%) having received prior treatment with paclitaxel. There were two (7.7%) partial responses, eight patients (30.8%) with stable disease, and fourteen patients (53.8%) with increasing disease. The most frequently reported adverse events were leucopenia, neutropenia, gastrointestinal, constitutional and peripheral neuropathy. Grade 3 and 4 adverse events were uncommon. CONCLUSIONS: Docetaxel, at the dose and schedule tested, has modest activity in this patient population.

Nursing research in the Gynecologic Oncology Group.

OBJECTIVES: To review nursing science history within the Gynecology Oncology Group (GOG); to discuss challenges of nursing science in the cooperative group (CG) using a current nurse-led protocol (GOG-0259) as an exemplar; and to propose recommendations to advance nursing science in the CG setting. DATA SOURCES: Indexed citations and personal experience. CONCLUSION: Benefits of CG research include opportunities for inter-disciplinary collaboration and ability to rapidly accrue large national samples. Challenges include limited resources to support non-treatment trials, a burdensome protocol approval process, and lack of experience with nursing/quality-of-life intervention studies. Formal GOG structures need to evolve to encourage nurse scientists to become active members; promote collaboration between experienced GOG advanced practice nurses and nurse scientists to identify nursing research priorities; and consider new funding sources to support pilot intervention studies. IMPLICATIONS FOR NURSING PRACTICE: Understanding the CG research process is critical for nurse scientists. A multi-disciplinary team of CG leaders can help investigators navigate a complex research environment and increase awareness of the value of nursing research.

Optical coherence tomography findings during pegaptanib therapy for neovascular age-related macular degeneration.

BACKGROUND: To evaluate macular thickness measured by optical coherence tomography (OCT) during pegaptanib therapy for neovascular age-related macular degeneration (AMD). METHODS: For this prospective, nonrandomized, observational case series, 41 eyes from 41 patients with neovascular AMD received intravitreous pegaptanib (1 mg) injections repeated every 6 weeks. The primary outcome measure was central foveal thickness measured by OCT. Secondary outcomes were fluorescein angiographic leakage and visual acuity. RESULTS: Mean thickness of the central area on OCT decreased from 340 +/- 24 microm to 299 +/- 14 microm after 12 weeks of pegaptanib injections. This represents a reduction in thickening of 32%. Fluorescein angiograms with definite leakage decreased from 100% to 81%, and mean visual acuity decreased from 20/116 to 20/120. CONCLUSIONS: Intravitreal injections of pegaptanib at 6-week intervals result in a moderate reduction of central foveal thickness in eyes with subfoveal neovascular AMD. This presents a modest effect relative to that reported with other anti-angiogenic agents.

Intravitreal bevacizumab (Avastin) treatment of neovascular age-related macular degeneration.

PURPOSE: To report the change in visual acuity and central retinal thickness by optical coherence tomography (OCT) after intravitreal injections of bevacizumab for the treatment of neovascular age-related macular degeneration (AMD). METHODS: A retrospective case series in a university-based practice evaluated patients with subfoveal choroidal neovascularization (CNV) due to AMD. Patients received intravitreal injections (1.25 mg) of bevacizumab and were monitored monthly with determination of best-corrected ETDRS visual acuity and OCT for persistence of retinal thickening. Eyes were retreated on an "as needed" basis, defined by presence of intraretinal or subretinal fluid. Patients were monitored every 2 months to 3 months for persistence of angiographic leakage. RESULTS: Seventy-nine eyes of 74 consecutive patients received the initial injection of bevacizumab between August 1, 2005, and January 30, 2006. Sixty-eight eyes (86%) of 64 patients had at least 3 months of follow-up. Mean central retinal thickness +/- SD decreased from 304 +/- 83 microm at baseline to 237 +/- 105 microm at 3 months (P = 0.00002). Mean ETDRS visual acuity gained 4 letters from 20/100 at baseline to 20/80-1 at 3 months (P = 0.040). Twenty eyes (25%) appeared to have a sustained response to a single injection and did not require further injections through 3 months. Two patients had a potentially drug-related adverse event (ischemic stroke and myocardial infarction). No serious injection-related adverse events occurred. CONCLUSIONS: Intravitreal bevacizumab injection affects a rapid decrease in retinal thickness to normal or near-normal levels and improvement in visual acuity in eyes with CNV due to AMD. The sustainability of changes in retinal thickness and visual acuity in response to bevacizumab treatment warrant further investigation and long-term follow-up.

A randomized clinical trial of a videotape intervention for women with chemotherapy-induced alopecia: a gynecologic oncology group study.

PURPOSE/OBJECTIVES: To evaluate changes in body image and self-esteem in women with gynecologic malignancies who experience chemotherapy-induced alopecia and to examine the effectiveness of a videotape intervention on body image and self-esteem. DESIGN: A prospective, randomized study. SETTING: Subjects were accrued from 11 Gynecologic Oncology Group (GOG) member institutions participating in 14 GOG treatment protocols. SAMPLE: 136 women with chemotherapy-induced alopecia, a mean age of 57.7 years, and advanced disease at study entry. METHODS: Prior to the first course of chemotherapy, all subjects received standard counseling regarding hair loss. Body image and self-esteem scores were obtained prior to course 1 and 3 and after course 4 of chemotherapy. Prior to course 3, women with grade 2 alopecia were allocated randomly to the videotape intervention or no intervention. MAIN RESEARCH VARIABLES: Total body image and self-esteem as measured by the Body Cathexis/Self-Cathexis Scale (BCSCS). FINDINGS: A small but statistically significant change (p = 0.045) in body image was observed after chemotherapy-induced alopecia, with no change in self-esteem. The videotape did not produce a significant effect on body image score. CONCLUSIONS: The study results support prior studies that have reported changes in body image as a result of chemotherapy-induced alopecia. The intervention employed (a videotape) was not effective. The BCSCS is a simple and quick measurement for use in future studies IMPLICATIONS FOR NURSING: Chemotherapy-induced alopecia has an adverse effect on body image. Novel interventions are needed to assist women in coping with this consequence of treatment.

Phase II evaluation of 3-day topotecan with cyclophosphamide in the treatment of recurrent ovarian cancer.

OBJECTIVE: The aim of this trial was to investigate the toxicity and efficacy of a 3-day topotecan administration schedule in combination with cyclophosphamide in the management of recurrent ovarian cancer. METHODS: Patients with recurrent measurable ovarian cancer who had up to two prior chemotherapy regimens for the management of their disease participating in this phase II trial were to receive topotecan at a dose of 1.25 mg/m(2)/day x 3 days in combination with cyclophosphamide at 600 mg/m(2) on Day 1 every 21 days. Dose escalation and reductions were permitted. RESULTS: A total of 36 patients (median age = 65; range 37-84) were treated with this combination regimen. Seventeen were platinum-sensitive and 19 were platinum-resistant. A total of 169 cycles of chemotherapy was administered (median = 4; range 1-10). Major toxicity included grade 4 neutropenia (68.6%), neutropenic fever (7.1%), grade 3 thrombocytopenia (18.3%), and requirement for blood transfusion (19.5%). Dose escalation was possible in 3 (8.3%), and dose reduction was required in 14 (38.9%) patients. Overall response rate was 25 and 44.5% stable disease. Median progression-free interval and overall survival was 5.4 and 23.5 months, respectively, independent of platinum sensitivity. CONCLUSION: The 3-day topotecan schedule in combination with cyclophosphamide appears to have good activity in recurrent ovarian cancer regardless of platinum sensitivity. Neutropenia was the only severe toxicity and was less prevalent than other reported trials of topotecan. This tolerable regimen offers patients more convenience and appears to have moderate activity.
