Abstract
OBJECTIVE Obesity represents an exponentially growing preventable disease leading to different health complications, particularly when associated with cancer. In recent years, however, an 'obesity paradox' has been hypothesized where obese individuals affected by cancer counterintuitively show better survival rates. The aim of this systematic review and meta-analysis is to assess whether the prognosis in gynecological malignancies is positively influenced by obesity. METHODS This study adheres to PRISMA guidelines and is registered with PROSPERO. Studies reporting the impact of a body mass index (BMI) of >30 kg/m2 compared with <30 kg/m2 in patients with gynecological cancers listed in PubMed, Google Scholar and ClinicalTrials.gov were included in the analysis. The Quality Assessment of Diagnostic Accuracy Studies 2 tool (QUADAS-2) was used for quality assessment of the selected articles. RESULTS Twenty-one studies were identified for the meta-analysis, including 14 108 patients with cervical, ovarian, or endometrial cancer. There was no benefit in 5-year overall survival for obese patients compared with non-obese patients (OR 1.2, 95% CI 1.00 to 1.44, p=0.05; I2=71%). When pooling for cancer sub-groups, there were no statistically significant differences in 5-year overall survival in patients with cervical cancer and 5-year overall survival and progression-free survival in patients with ovarian cancer. For obese women diagnosed with endometrial cancer, a significant decrease of 44% in 5-year overall survival (p=0.01) was found, with no significant difference in 5-year disease-free survival (p=0.78). CONCLUSION According to the results of the present meta-analysis, a BMI of ≥30 kg/m2 does not have a positive prognostic effect on survival compared with a BMI of <30 kg/m2 in women diagnosed with gynecological cancers. The existence of the 'obesity paradox' in other fields, however, suggests the importance of further investigations with prospective studies.

Abstract
The effect of obesity on wound-related outcomes in post-ovarian cancer patients is not clear. A number of studies on the association of fat with post-operation injury in ovarian carcinoma have produced contradictory findings. This study aims to conduct a study of the available data to assess the association of obese individuals with significant surgery results in ovarian cancer. We looked up Cochrane Library, Embase, and PubMed for qualifying research on ovarian cancer operations to determine the primary evidence for evaluating the association of obesity with post-surgical wound injury in ovarian cancer. The odds ratio (OR) was analysed with a fixed effect model if the variability of the study was small; otherwise, the analysis of the data was done with a random effect model. Out of 1259 related trials which were reviewed for eligibility, 6 publications were chosen from 2009 to 2019, 3076 patients who had had an operation for ovarian cancer. Obesity has been linked to an increased rate of wound-related complications in ovarian cancer operations compared to those without obesity (OR, 0.50; 95% CI, 0.37, 0.69 p < 0.0001). Non-obesity was significantly less likely to occur with respect to operation time compared to those with obesity (MD, -48.00; 95% CI, -55.33, -40.68 p < 0.00001). There were no statistically significant differences in the rate of haemorrhage after the operation (OR, 0.26; 95% CI, 0.04, 1.57, p = 0.14). Because of the limited number of trials in this meta-analysis, caution should be exercised in their treatment. More high-quality research with a large sample is required in order to confirm the findings.

Association between Energy Balance-Related Factors and Clinical Outcomes in Patients with Ovarian Cancer: A Systematic Review and Meta-Analysis. Cancers (Basel) 2022; 14:cancers14194567. [PMID: 36230490 PMCID: PMC9559499 DOI: 10.3390/cancers14194567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Revised: 09/01/2022] [Accepted: 09/04/2022] [Indexed: 12/04/2022] Open
Abstract
Background: This systematic review and meta-analysis synthesized evidence in patients with ovarian cancer at diagnosis and/or during first-line treatment on; (i) the association of body weight, body composition, diet, exercise, sedentary behavior, or physical fitness with clinical outcomes; and (ii) the effect of exercise and/or dietary interventions. Methods: Risk of bias assessments and best-evidence syntheses were completed. Meta-analyses were performed when ≥3 papers presented point estimates and variability measures of associations or effects. Results: Body mass index (BMI) at diagnosis was not significantly associated with survival. Although the following trends were not supported by the best-evidence syntheses, the meta-analyses revealed that a higher BMI was associated with a higher risk of post-surgical complications (n = 5, HR: 1.63, 95% CI: 1.06−2.51, p = 0.030), a higher muscle mass was associated with a better progression-free survival (n = 3, HR: 1.41, 95% CI: 1.04−1.91, p = 0.030) and a higher muscle density was associated with a better overall survival (n = 3, HR: 2.12, 95% CI: 1.62−2.79, p < 0.001). Muscle measures were not significantly associated with surgical or chemotherapy-related outcomes. Conclusions: The prognostic value of baseline BMI for clinical outcomes is limited, but muscle mass and density may have more prognostic potential. High-quality studies with comprehensive reporting of results are required to improve our understanding of the prognostic value of body composition measures for clinical outcomes. Systematic review registration number: PROSPERO identifier CRD42020163058.

Abstract
Granulocyte-colony stimulating factor (G-CSF) stimulates bone marrow progenitor cell proliferation and enhances neutrophil production. Exogenous G-CSF administration is indicated for chemotherapy-induced neutropenia management. However, there is a paucity of basic research examining the effects of the concomitant use of G-CSF and chemotherapy on myeloid cells in vivo. Whether concomitant G-CSF and chemotherapy adversely affect myeloid cell proliferation have not been determined. Herein, we examined the effects of the concomitant use of pegfilgrastim and 5-fluorouracil on myeloid cells and peripheral blood cells in mouse models. Balb/c mice were treated intraperitoneally with 5-fluorouracil (20 μg/g b.w.) or a vehicle as a control for 5 days, and pegfilgrastim was administered subcutaneously at 1 μg/g b.w. on day 3. As a result, we demonstrated that the concomitant use of pegfilgrastim suppressed the 5-fluorouracil-induced decrease of granulocytic cells in both bone marrow and peripheral blood in mice. To assess the clinical efficacy of early administration of pegfilgrastim during docetaxel, cisplatin, and 5-fluorouracil therapy in patients with esophageal cancer, we retrospectively identified 42 consecutive patients treated with this regimen. The incidence of both febrile neutropenia and grade 4 neutropenia was significantly lower in patients who received pegfilgrastim than in those who did not receive it (P = 0.002 and P = 0.002, respectively). These results suggest that the concomitant use of pegfilgrastim and chemotherapy, consisting of continuous infusions of 5-fluorouracil, improved chemotherapy-induced neutropenia without detrimental effects on proliferating myeloid granulocytic cells.

Abstract
BACKGROUND The impact of obesity on the surgical outcomes in patients after primary ovarian cancer surgery is unclear. We aimed at conducting a meta-analysis to evaluate the associations between obesity and major surgical outcomes in ovarian cancer patients. METHOD Embase, PubMed and Web of Science databases were searched for eligible studies. Study-specific relative risks (RR) were pooled using fixed effect model when little evidence of heterogeneity was detected, otherwise random effect model was employed. RESULTS Twelve eligible studies were identified. The pooled incidence rates of all complications were 38% (95% CI: 29%, 47%) for obese patients and 27% (95% CI: 18%, 36%) for non-obese patients. Compared with the non-obese patients, there was a significantly increased risk of all complications in obese patients after ovarian cancer surgery, with a pooled RR of 1.75 (95% CI: 1.26, 2.43). For advanced (stages III-IV) ovarian cancer, the pooled RR of all complications was 1.55 (95% CI: 1.07, 2.24). Obese patients after ovarian cancer surgery were at higher risks of wound complication (pooled RR: 7.06, 95% CI: 3.23, 15.40) and infection (pooled RR: 1.94, 95% CI: 1.47, 2.55) compared with non-obese patients. Such increased risk was not observed for other major complications, namely, venous thromboembolism, ileus and organ failure. Hospital stay days between obese patients and non-obese patients were similar (Standardized Mean Difference: -0.28, 95% CI: -0.75, 0.19). The rates of optimal debulking (pooled RR: 0.96, 95% CI: 0.90, 1.03), readmission/return to operation room (pooled RR: 1.20, 95% CI: 0.56, 2.57) and 30-day mortality (pooled RR: 0.95, 95% CI: 0.54, 1.66) were also comparable between obese patients and non-obese patients. CONCLUSION Obesity is associated with an increased risk of postoperative complications, especially wound complications and infection after primary ovarian cancer surgery. Obesity may not affect their optimal debulking rates and 30-day mortality in patients undergoing ovarian cancer surgery. Besides, to improve surgical outcomes, an advanced minimally invasive robotic approach seems to be feasible for the treatment of obese patients with ovarian cancer.

Abstract
One-fifth of cancer deaths are associated with obesity. Because the molecular mechanisms by which obesity affects the progression of ovarian cancer (OC) are poorly understood, we investigated if obesity could promote the progression of OC cells using the postmenopausal ob/ob mouse model and peritoneal dissemination of mouse ID8 OC cells. Compared to lean mice, obese mice had earlier OC occurrence, greater metastasis throughout the peritoneal cavity, a trend toward shorter survival, and higher circulating glucose and proinflammatory chemokine CXCL1 levels. Ascites in obese mice had higher levels of macrophages (Mφ) and chemokines including CCL2, CXCL12, CXCL13, G-CSF and M-CSF. Omental tumor tissues in obese mice had more adipocytes than lean mice. Our data suggest that obesity may accelerate the peritoneal dissemination of OC through higher production of pro-inflammatory chemokines and Mφ recruitment.

Abstract
Measures of body weight and anthropometrics such as body mass index (BMI) are commonly used to assess nutritional status in clinical conditions including cancer. Extensive research has evaluated associations between body weight and prognosis in ovarian cancer patients, yet little is known about the potential impact of body composition (fat mass (FM) and fat-free mass (FFM)) in these patients. Thus, the purpose of this publication was to review the literature (using PubMed and EMBASE) evaluating the impact of body weight and particularly body composition on surgical complications, morbidity, chemotherapy dosing and toxicity (as predictors of prognosis), and survival in ovarian cancer patients. Body weight is rarely associated with intra-operative complications, but obesity predicts higher rates of venous thromboembolism and wound complications post-operatively in ovarian cancer patients. Low levels of FM and FFM are superior predictors of length of hospital stay compared to measures of body weight alone, but the role of body composition on other surgical morbidities is unknown. Obesity complicates chemotherapy dosing due to altered pharmacokinetics, imprecise dosing strategies, and wide variability in FM and FFM. Measurement of body composition has the potential to reduce toxicity if the results are incorporated into chemotherapy dosing calculations. Some findings suggest that excess body weight adversely affects survival, while others find no such association. Limited studies indicate that FM is a better predictor of survival than body weight in ovarian cancer patients, but the direction of this relationship has not been determined. In conclusion, body composition as an indicator of nutritional status is a better prognostic tool than body weight or BMI alone in ovarian cancer patients.

Abstract
Malnutrition and underweight status pose an unfavorable prognosis for cancer patients. Several studies have addressed the impact of a low body mass index (BMI) (<18.5 kg/m(2)) on ovarian cancer progression. However, their results seem to be conflicting. The present meta-analysis investigates whether the underweight status negatively affects the progress of ovarian cancer. We conducted a systematic review searching the Medline (1966-2014), Scopus (2004-2014), Popline (1974-2014), ClinicalTrials.gov (2008-2014), and Cochrane Central Register of Controlled Trials (CENTRAL) (1999-2014) databases together with reference lists from included studies. All prospective and retrospective observational cohort studies were included. Statistical meta-analysis was performed using the RevMan 5.1 software. Current evidence suggests that the stage of the disease does not differ between underweight and normal-weight patients [odds ratio (OR) 0.80, 95% confidence interval (CI) 0.46-1.39 for stage I; OR 1.27, 95% CI 0.71-2.27 for stage II; OR 1.03, 95% CI 0.71-1.51 for stage III; and OR 1.05, 95% CI 0.63-1.76 for stage IV disease]. Concurrently, the risk of residual disease after surgery (OR 1.03, 95% CI 0.69-1.52) and the risk of dying due to ovarian cancer (OR 1.08, 95% CI 0.64-1.85) seem to be similar. According to the findings of our systematic review, the underweight status does not seem to have a detrimental impact on ovarian cancer prognosis. However, the methodological limitations of published studies and the small number of enrolled underweight patients preclude firm results. Thus, future research in this field is necessary.

Abstract
OBJECTIVE To evaluate the effect of body mass index on the surgical outcomes in ovarian cancer patients. In addition, we performed a systematic review to compare our outcomes with the current literature. DESIGN Retrospective cohort study and a systematic review of the literature. SETTING Gynaecology department at the Royal Cornwall Hospital Trust. POPULATION Surgically managed stage I-IV ovarian cancer patients between September 2006 and September 2014. METHODS Primary and secondary outcome measures were evaluated across BMI categories; BMI <25 kg/m², BMI 25–29.9 kg/m², BMI ≥30 kg/m² and BMI ≥40 kg/m². A systematic review was performed according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. MAIN OUTCOME MEASURES The primary outcome measure was surgical complications. Secondary outcome measures were other intra- and postoperative outcomes. RESULTS Two hundred twenty-eight women were included in the study, of which 84 had a BMI <25 kg/m², 84 women had a BMI 25–29.9 kg/m², and 60 women were obese (BMI ≥30 kg/m²), 13 of whom were morbidly obese. Morbid obesity was associated with increased rates of wound complications. However, BMI did not show an association with other outcomes. In the review, an increasing BMI was associated with increased rates of wound complications and prolonged hospital stay, but did not impact other surgical outcomes. CONCLUSION Obesity is associated with increased rates of wound complications and a prolonged hospital stay, but does not appear to affect other operative outcomes including cytoreduction status and 30-day mortality. Therefore, operative management and postoperative care require a multifactorial approach to minimise adverse outcomes.

Abstract
OBJECTIVE To describe the effects of obesity on the pharmacokinetics and dosing of chemotherapies and provide recommendations for chemotherapy management in obese women with gynecologic malignancies. METHODS PubMEd and MEDLINE databases were searched for articles published before June 2014. Only English-language articles were considered. 84 manuscripts were reviewed and 66 were included. Search terms included: obesity, overweight, body mass index, body surface area, glomerular filtration rate, chemotherapy, ovarian cancer, endometrial cancer, inflammation, and pharmacokinetics, RESULTS Obese cancer patients have worse clinical outcomes, compared with non-obese patients. This may be because of differences in pharmacokinetics, metabolic dysregulation, or physicians' decisions to reduce chemotherapy dose-intensity during treatment to minimize toxicities. A 2012 American Society of Clinical Oncology Clinical Practice Guideline recommends using actual body weight for chemotherapy dosing in all patients treated with curative intent, irrespective of obesity, to avoid compromising clinical outcomes, including progression free survival (PFS) and overall survival (OS). In women with gynecologic cancers most studies demonstrate no difference in PFS or OS when obese patients receive the same chemotherapy dose intensity as non-obese patients, except perhaps with bevacizumab. CONCLUSIONS Chemotherapy dose-intensity is a critical determinant of cancer outcomes and should be maintained in all patients, irrespective of obesity. Future studies should prospectively examine the impact of obesity on clinical outcomes (adverse events, survival) to improve the care of this growing population of patients who are at risk for inferior clinical outcomes.

Abstract
OBJECTIVE The objective of this study was to evaluate prognostic risk factors for survival in women with low-grade serous epithelial ovarian cancer (LGSC). METHODS A multicenter retrospective analysis of patients with LGSC was conducted. Potential epidemiologic risk factors evaluated included obesity, age, parity, race, smoking, oral contraceptive pill and/or hormonal replacement therapy use, and previous hysterectomy or surgery on fallopian tubes and/or ovaries. Additional factors included stage, extent of debulking, residual disease, and disease status. RESULTS Eighty-one patients were identified, and pathologic diagnosis was independently confirmed. Median age at diagnosis was 56 years (range, 21-86 years). Thirty-four percent were obese, and 80% had optimally debulked disease. Forty-six percent were alive, 14% with disease, whereas 25% were dead of disease, 2% died of intercurrent disease, and 27% had an unknown status. In a univariate analysis, optimal surgical debulking was associated with improved progression-free survival (P = 0.01), disease-specific survival (P = 0.03), and overall survival (OS) (P < 0.001) and body mass index with worse OS (P = 0.05). On multivariate analysis, obesity (hazard ratio, 2.8; 95% confidence interval, 1.05-7.3; P = 0.04) and optimal tumor debulking (hazard ratio, 0.05; 95% confidence interval, 0.008-0.29; P = 0.001) were a significant predictor of OS. CONCLUSIONS In a multivariate analysis, obesity and optimal tumor cytoreduction were significant predictors of OS. However, obesity was not associated with worse disease-specific survival, suggesting that mortality of obese patients with LGSC may result from other comorbidities. Interventions addressing obesity may improve survival for women diagnosed with LGSC, and further study is warranted to address the role of obesity in LGSC.

Abstract
Controversy remains regarding the effect of obesity on the survival of patients with ovarian cancer in Asia. This study examined the impact of obesity on the survival outcomes in advanced epithelial ovarian cancer (EOC) using Asian body mass index (BMI) criteria. The medical records of patients undergoing surgery for advanced (stage III and IV) EOC were reviewed. Statistical analyses included ANOVA, chi-square test, Kaplan-Meier survival and Cox regression analysis. Among all 236 patients, there were no differences in overall survival according to BMI except in underweight patients. In a multivariate Cox analysis, surgical optimality and underweight status were independent and significant prognostic factors for survival (HR, 2.302; 95% CI, 1.326-3.995; P=0.003 and HR, 8.622; 95% CI, 1.871-39.737; P = 0.006, respectively). In the subgroup of serous histology and optimal surgery, overweight and obese I patients showed better survival than normal weight patients (P = 0.012). We found that underweight BMI and surgical optimality are independent risk factors for the survival of patients with advanced ovarian cancer. High BMI groups (overweight, obese I and II) are not associated with the survival of advanced EOC patient. However, in the subgroup of EOC patients with serous histology and after optimal operation, overweight and obese I group patients show better survival than the normal weight group patients.

Abstract
BACKGROUND Ovarian cancer is often diagnosed at late stages and consequently the 5-year survival rate is only 44%. However, there is limited knowledge of the association of modifiable lifestyle factors, such as physical activity and obesity on mortality among women diagnosed with ovarian cancer. The purpose of our study was to prospectively investigate the association of (1) measured body mass index (BMI), and (2) self-reported physical activity with ovarian cancer-specific and all-cause mortality in postmenopausal women enrolled in the Women's Health Initiative (WHI). METHODS Participants were 600 women diagnosed with primary ovarian cancer subsequent to enrollment in WHI. Exposure data, including measured height and weight and reported physical activity from recreation and walking, used in this analysis were ascertained at the baseline visit for the WHI. Cox proportional hazard regression was used to examine the associations between BMI, physical activity and mortality endpoints. RESULTS Vigorous-intensity physical activity was associated with a 26% lower risk of ovarian cancer specific-mortality (HR=0.74; 95% CI: 0.56-0.98) and a 24% lower risk of all-cause mortality (HR=0.76; 95% CI: 0.58-0.98) compared to no vigorous-intensity physical activity. BMI was not associated with mortality. CONCLUSIONS Participating in vigorous-intensity physical activity, assessed prior to ovarian cancer diagnosis, appears to be associated with a lower risk of ovarian cancer mortality.

Abstract
OBJECTIVE The purpose of this study was to compare primary debulking surgery (PDS) vs neoadjuvant chemotherapy with interval debulking surgery (NACT-IDS) among obese patients. STUDY DESIGN Medical records of patients with a body mass index (BMI) of ≥30 kg/m(2) with ovarian/fallopian tube/primary peritoneal carcinoma between January 2005 and December 2010 were reviewed. Patients were separated by PDS or NACT-IDS. Preoperative characteristics, surgical procedures, and postoperative and oncologic outcomes were compared. RESULTS Of 117 patients, 95 women (81.2%) underwent PDS, and 22 women (18.8%) underwent NACT-IDS. Patients who underwent NACT-IDS were more likely to have stage IV disease (63.6% vs 26.3%; P = .001) and a low surgical complexity score (n = 14; 63.6%). There were no other differences between groups with respect to preoperative characteristics or postoperative morbidity. Compared with the NACT-IDS group, the PDS group had an improved progression-free survival (PFS; 15 vs 11 months; P = .006) and overall survival (OS; 53 vs 32 months; P = .036). Seventy-eight patients (66.7%) had a BMI of 30-34.9 kg/m(2). Within this subset of obese patients, the PDS group had an improved PFS (15 vs 10 months; P = .011) and OS (58 vs 32 months; P = .033), compared with the NACT-IDS group. Among patients with a BMI of ≥35 kg/m(2), there was no difference in PFS (14 vs 12 months; P = .316) or OS (38 vs 32 months; P = .640) when the PDS and NACT-IDS groups were compared. CONCLUSION Patients with a BMI of 30-34.9 kg/m(2) who undergo PDS have improved oncologic outcomes, compared with those women who undergo NACT-IDS. Patients with a BMI of ≥35 kg/m(2) who undergo PDS have similar oncologic outcomes to those who undergo NACT-IDS. Complication rates were similar at all BMIs, regardless of treatment approach.

Abstract
Studies that have examined the association between obesity and ovarian cancer survival have provided conflicting results. We reviewed and quantitatively summarized existing evidence, exploring potentially important sources of variability, such as the timing of body mass index (BMI) assessment and different cutpoints used to categorize BMI. A systematic search of MEDLINE and EMBASE was conducted to identify original data evaluating the association between obesity and survival in women with ovarian cancer. Adjusted hazard ratios (HR) from studies were pooled using a random-effects model. The meta-analysis of 14 studies showed slightly poorer survival among obese than in non-obese women [pooled HR, 1.17; 95% confidence interval (CI), 1.03-1.34]. This estimate did not vary appreciably when BMI was measured before diagnosis (1.13; 0.95-1.35), at the time of diagnosis (1.13; 0.81-1.57) or at the commencement of chemotherapy (1.12; 0.96-1.31). We found a slightly stronger association in studies that only included women with a BMI ≥ 30 in their "obese" group (1.20) than in studies that also included overweight women (BMI ≥ 25; 1.14). Women with ovarian cancer who are obese appear to have slightly worse survival than non-obese women. However, there is a large amount of inter-study variation, which means that no solid conclusions can be drawn.

Abstract
OBJECTIVE Although obesity is shown to be a risk factor for epithelial ovarian cancer, its role as a prognostic factor has been remained inconclusive. In this study, available evidences on this matter to date have been assembled for a meta-analysis to determine the effect of obesity on the survival of patients with epithelial ovarian cancer. MATERIALS AND METHODS Eligible studies published up to December 2010 were searched using MEDLINE (PubMed), EMBASE, and Cochrane Central Register of Controlled Trials, and manual review of relevant bibliography to look for additional studies was done. Adjusted hazard ratios (HRs) from individual studies were pooled using a random-effects model. RESULTS Ten cohort studies of 331 screened articles were included in the final analysis. The meta-analysis showed overweight or obesity at early adulthood to be associated with higher mortality among patients with ovarian cancer (HR, 1.60; 95% confidence interval, 1.10-2.34). Among patients with advanced ovarian cancer, premorbid obesity was associated with worse prognosis (HR, 1.45; 95% confidence interval, 1.09-1.93). However, there was no significant relationship between prognosis and obesity around the time of diagnosis. CONCLUSIONS This study suggests a possible relationship between obesity at early adulthood and higher mortality among patients with ovarian cancer. Further studies are needed to elucidate the harmful effect of obesity on the survival of patients with ovarian cancer.

Abstract
BACKGROUND Obesity is a known risk factor and poor prognostic factor for many comorbidities including cancer. However, the influence of body mass index (BMI) on ovarian cancer outcomes is inconclusive. Therefore, the objective of this study was to evaluate the impact of BMI and weight changes on survival in patients with advanced ovarian cancer after primary treatment. METHODS All patients with a diagnosis of advanced epithelial ovarian cancer from January 2000 to December 2007 undergoing primary cytoreductive surgery and adjuvant chemotherapy were identified. Patients were divided into 3 categories: underweight/normal weight (BMI, <25 kg/m), overweight (BMI, 25-30 kg/m), and obese (BMI, >30 kg/m). Adjusted hazard ratios for progression-free survival (PFS) and overall survival (OS) were calculated via Cox proportional hazards models. RESULTS One hundred ninety-eight patients met the inclusion criteria. For all patients, the mean BMI was 26 kg/m (range, 16.4-49.1 kg/m), with 43% of patients being classified as normal weight, 29% overweight, and 28% as obese. Median 5-year OS was 48.2 months (95% confidence interval, 16.4-49.1 months), and no differences in OS were noted between BMI groups. Unadjusted median PFS for patients with normal weight was 13.7 months, compared with 15.5 and 17.9 months for the overweight and obese groups. Adjusted analysis of BMI over time indicates a trend of increased risk for patients who gain weight in the 6 months after primary therapy on disease progression (hazard ratio, 1.68; 95% confidence interval, 0.87-3.26). CONCLUSIONS After adjustment for confounders, such as stage, grade, histology, age, and debulking status, data suggest a trend toward a shorter PFS in patients with a normal BMI. However, OS was not significantly related to BMI, and weight change in the 6 months after completion of treatment had no effect on PFS or OS. Further research should be directed at elucidating relationships between weight and cancer biology.

Abstract
OBJECTIVE The purpose of this study was (1) to investigate the association between BMI self-reported at three time points (during their 20s, 5 years before diagnosis, and post-diagnosis) and mortality among 388 women with newly diagnosed epithelial ovarian cancer and (2) weight change between these 3 time points and mortality. METHODS Women completed interview-administered questionnaires on average 9 months post-diagnosis. Women were followed 5 years after diagnosis or until death, whichever came first. Cox proportional hazard regression was used to estimate associations between BMI during the 20s, BMI 5 years prior to diagnosis, BMI post-diagnosis (i.e., at the time of interview) and weight changes between these time points and mortality. RESULTS The 5-year survival rate was 54% (178 deaths, 146 from ovarian cancer). BMI measured continuously at all three time points was associated with a higher risk of ovarian cancer mortality (P≤0.05). The strongest association was observed with BMI in the 20s and all-cause mortality comparing women with BMI≥25 kg/m(2) to BMI<25 kg/m(2) (HR=1.82; 95% CI, 1.02-3.27; P for trend=0.045). For weight change from the 20s to 5 years prior to diagnosis and ovarian cancer specific mortality, we observed a 68% higher risk of ovarian cancer mortality (HR=1.68; 95% CI, 1.11-2.55; P for trend=0.015, comparing women with <10 lbs weight gain to women with ≥10 lbs weight gain). CONCLUSION BMI prior to and after diagnosis and weight gain throughout adulthood is associated with ovarian cancer mortality.

Abstract
BACKGROUND High body mass index (BMI), a prevalent condition in the United States, is associated with esophageal adenocarcinoma (EAC). Its influence on a patient's outcome remains unclear. In the current study, the authors examined the impact of BMI on survival and complications in patients with esophageal cancer (EC) who underwent surgery as their primary therapy. METHODS The authors retrospectively reviewed 301 consecutive EC patients who underwent surgery but received no adjunctive therapy. Patients were segregated into 2 subgroups based on their baseline BMI: normal/low (<25 kg/m(2) ) and high (≥25 kg/m(2) ). RESULTS Seventy-six (25%) patients had a BMI <25 kg/m(2) and 225 (75%) patients had a BMI ≥25 kg/m(2) . In the high BMI group, there were more men (P < .001), fewer upper ECs (P = .021), a lower baseline clinical stage (P = .006), and frequent EAC (P < .001). Postoperative morbidity was similar in both groups, with the exception of gastrointestinal complications (P = .016). The 5-year overall survival (OS) rates were 44% in the normal/low BMI group and 60% in the high BMI group (P = .017). The 5-year disease-free survival (DFS) rates were 41% in the normal/low BMI group and 60% in the high BMI group (P = .005). On multivariable analysis, age, weight loss, peripheral vascular disease (PVD), and both clinical and pathological stage of disease were found to be independent prognosticators for OS. Older age (hazard ratio [HR], 1.029; 95% confidence interval [95% CI], 1.009-1.049 [P = .004]), weight loss (HR, 1.525; 95% CI, 1.034-2.248 [P = .033]), and PVD (HR, 2.325; 95% CI, 1.039-5.204 [P = .040]) were found to be associated with poor OS. CONCLUSIONS High BMI is common in EC patients and the better OS/DFS noted in patients with a high BMI is because of the diagnosis of a low baseline clinical stage. Confirmation of these findings is warranted.

Abstract
Diet, physical activity, and weight may affect prognosis among women who are diagnosed with breast or gynecologic cancer. Observational studies show associations between being overweight or obese and weight gain with several measures of reduced prognosis in women with breast cancer and some suggestion of poor prognosis in underweight women. Observational studies have shown an association between higher levels of physical activity and improved breast cancer-specific and all-cause mortality, although a dose-response relationship has not been established. One large randomized controlled trial reported increased disease-free survival after a mean of 5 years in patients with breast cancer randomly assigned to a low-fat diet versus control. However, another trial of similar size found no effect from a high vegetable/fruit, low-fat diet on breast cancer prognosis. The few reported studies suggest that obesity negatively affects endometrial cancer survival, while the limited data are mixed for associations of weight with ovarian cancer prognosis. Insufficient data exist for assessing associations of weight, physical activity, or diet with prognosis in other gynecologic cancers. Associations of particular micronutrient intake and alcohol use with prognosis are not defined for any of these cancers. The effects of dietary weight loss and increase in physical activity on survival or recurrence in breast and gynecologic cancers are not yet established, and randomized controlled trials are needed for definitive data.
