Malnutrition as a predictor of poor postoperative outcomes in gynecologic cancer patients.

PURPOSE: Poor nutritional status has been associated with increased postoperative morbidity and mortality in surgical patients. The purpose of this study is to evaluate if decreased nutritional parameters correlate with increased postoperative complications regardless of other risk factors in the gynecologic cancer patient. METHODS: A retrospective chart review was performed among women who underwent surgical management for gynecologic malignancies from October 2006 to June 2008. Variables included age, race, medical comorbidities, cancer type/stage, preoperative albumin, absolute lymphocyte count (ALC), and body mass index (BMI), estimated blood loss (EBL), intraoperative blood transfusion (BT), intraoperative or postoperative complications, intensive care unit (ICU) admissions, hospital readmissions, reoperations, and cancer recurrence. RESULTS: Three hundred gynecologic oncology patients with preoperative nutritional parameters were included in the study. Decreased albumin was significantly associated with more postoperative complications (p < 0.001), hospital readmissions (p = 0.01), reoperations (p = 0.03), ICU admissions (p < 0.001), and cancer recurrence (p < 0.001). Decreased ALC and BMI preoperatively was also significantly associated with higher incidence of cancer recurrence (p = 0.01, p = 0.01). Surgical cases involving increased EBL (p = 0.01, p < 0.001) and more BT (p < 0.001, p < 0.001) had significantly more postoperative complications and more ICU admissions. Multivariable logistic regression found preoperative albumin to be an independent predictor of increased postoperative complications. CONCLUSIONS: Decreased albumin is significantly associated with more postoperative complications, hospital readmissions, reoperations, ICU admissions, and cancer recurrence. This nutritional parameter is an important predictor of postoperative morbidity and mortality. Thus, it is important to assess nutritional status preoperatively and offer nutritional support or alternate treatment options if necessary.

Pegfilgrastim dosing on same day as myelosuppressive chemotherapy for ovarian or primary peritoneal cancer.

According to the prescribing information, pegfilgrastim should not be administered within 14 days prior to, or within 24 hours after, the administration of cytotoxic chemotherapy. However, few data exist to support this recommendation. A single-institution retrospective review was conducted of all patients with ovarian or primary peritoneal cancer who received prophylactic pegfilgrastim on the same day as myelosuppressive chemotherapy from May 2003 to June 2006. Forty-six patients were treated for the following malignancies: 35 (76%) epithelial ovarian, 6 (13%) primary peritoneal, and 5 (11.0%) ovarian germ cell or stromal cell carcinoma. All patients met the current guidelines of using colony-stimulating factors for prophylaxis against febrile neutropenia. A total of 269 cycles of chemotherapy were administered. All patients received pegfilgrastim within 1 hour of the completion of chemotherapy administration. Grade 1 or 2 neutropenia developed in 10 cycles (3.7%), and the mean absolute neutrophil count was 4926/uL (range, 1,293-24,300). No patients had febrile neutropenic episodes, hospitalizations, or antibiotic use secondary to neutropenia, nor did they have dose reductions or chemotherapy delays due to neutropenia. Administration of pegfilgrastim on the same day as myelosuppressive chemotherapy in patients with ovarian or primary peritoneal cancer may be determined to be a convenient, safe, and effective approach.
