Introduction Studies have shown that body composition, age, gender, changes in monocyte count and repeated dosing alter pharmacokinetic properties of PEGylated liposomal doxorubicin (PLD). However, limited information exists regarding the clinical risk factors of ovarian cancer patients who develop palmar plantar erythrodysesthesia (PPE) while receiving PLD for cancer recurrence. Methods We conducted a retrospective cohort analysis of consecutive patients with recurrent ovarian and primary peritoneal cancer who were treated with PLD from 2005 to 2009. Clinical and pathologic data were abstracted from electronic medical records. Statistical analyses were performed using univariate and bivariate analyses, logistic regression, and log rank-tests. Results Twenty-three percent (31/133) of patients developed PPE. Age, body mass index (BMI), race, stage, and histology did not significantly differ between PPE and non-PPE patients. There was a possible trend for decreasing PPE with increasing body mass index (BMI) (24.5% of normal weight, 27.5% of overweight; 23.8% of obese class I; 13.3% of obese class II; and 0% of obese class III), though not statistically significant. The number of chemotherapy regimens prior to PLD, and the mean cycles of PLD received did not differ between patients with and without PPE. 77.4% of PPE cases occurred within the first 3 infusion cycles. PPE was not associated with time to progression. Conclusion Nearly one-quarter of ovarian cancer patients receiving PLD will develop PPE. Further investigation of factors such as BMI associated with PPE may aid in patient selection for PLD, and future development of other nanoparticle and liposomal agents. © 2013 Elsevier Inc.

Introduction Studies demonstrate that patient factors such as race, body composition, medical co-morbidities, and medications may be associated with cancer related outcomes independent of the patient's malignancy and related therapies for the cancer. The goal of this study is to determine demographic and prognostic factors affecting disease recurrence in women with early stage ovarian granulosa cell tumors (GCT). Materials and Methods This study used a dual-institution retrospective analysis of women diagnosed with GCT between 1995 and 2010. Demographics including age, race, body mass index (BMI), stage, diabetes (DM), adjuvant treatment, and progression-free survival (PFS) were extracted. Hazard ratios for recurrence were estimated by univariate and multivariate Cox regression models. Results One hundred and four women were identified with a median age of 50 years (range 12-87 years). Fifty-five (58.5%) were Caucasian, 29 (30.9%) African American, and 10 (10.2%) others. Median BMI was 29 kg/m2 (range 12-57 kg/m2). Twenty-one patients had DM. The majority of women had clinical stage I disease (95.0%), 5 (6.4%) had stage II/III disease, and 5 were unstaged. In univariate analysis among early stage disease, DM showed the strongest association with recurrence (HR = 3.37, 95% CI = 1.38-8.20). In multivariate analysis, DM was associated with an HR of 3.19 for recurrence (95% CI = 1.08-9.44). Conclusions Our results emphasize that diabetes is one of the strongest predictors of recurrent disease in patients with ovarian GCTs. As this disease is characterized by long disease-free intervals prior to recurrence, this may serve as a potential chemopreventive strategy in patients felt to be at higher risk for recurrence. © 2013 Elsevier Inc.
