Management of ovarian cancer in patients older than 80 years of Age

Ovarian cancer in the older patient: where are we now? What to do next?

In recent years, major advances have been made toward the individualization of epithelial ovarian cancer care, leading to an overall improvement of patient outcomes. However, real-life data indicate that the oldest populations do not benefit from this, due to aspects related to cancer (more aggressive histopathological features), treatment (i.e. frequently suboptimal), and the host (increased toxicities in patients with lower physiological reserve). A specific risk-benefit perspective should therefore be taken when considering surgery, chemotherapy, and maintenance treatments: the decision for cytoreductive surgery should include geriatric vulnerability and surgical complexity, neo-adjuvant chemotherapy being an option when primary surgery appears at high risk; carboplatin paclitaxel association remains the standard even in vulnerable older patients; and bevacizumab and poly(ADP-ribose) polymerase inhibitors maintenance are interesting options provided they are prescribed according to their indications with a close monitoring of their toxicities. Future studies should aim to individualize care without limiting access of older patients to innovation. A specific focus is needed on age-specific translational analyses (focusing on tumor mutational burden and impaired biological pathways), a better patient stratification according to geriatric parameters, an adaptation of both oncological treatment and geriatric interventions, and treatment adaptations not a priori but according to formal pharmacokinetic data.

Multi-Disciplinary Care Planning of Ovarian Cancer in Older Patients: General Statement-A Position Paper from SOFOG-GINECO-FRANCOGYN-SFPO

Simple Summary

This position paper aims to provide practitioners a proposal for multidisciplinary care planning for older patients with ovarian cancer from the time of suspected diagnosis. The first-line treatment of advanced ovarian cancer involves several interdependent sequences: cytoreductive surgery, (neo)adjuvant chemotherapy and maintenance targeted treatments. In older patients, care planning must be adapted to their geriatric parameters and consider the geriatric impact of each treatment sequence to allow treatment completion. Care planning should be centered on patient motivation and imply multidisciplinarity. Each step of treatment plan should be reconsidered in light of a geriatric assessment and follow-up. Studies are needed to prospectively evaluate the impact of geriatric vulnerability parameters at each step of the treatment agenda and the impact of geriatric interventions on patient outcomes.

Abstract

In this position paper the Société Francophone d’OncoGériatrie (SOFOG; French-speaking oncogeriatric society), the Société Française de Pharmacie Oncologique (SFPO, French society for oncology pharmacy), the Groupe d’Investigateurs Nationaux pour l’Étude des Cancers de l’Ovaire et du sein (GINECO, National Investigators’ Group for Studies in Ovarian and Breast Cancer) and the Groupe Français de chirurgie Oncologique et Gynécologique (FRANCOGYN) propose a multi-disciplinary care planning of ovarian cancer in older patients. The treatment pathway is based on four successive decisional nodes (diagnosis, resectability assessment, operability assessment, adjuvant, and maintenance treatment decision) implying multidisciplinarity and adaptation of the treatment plan according to the patient’s geriatric covariates and her motivation towards treatment. Specific attention must be paid to geriatric intervention, supportive care and pharmaceutical conciliation. Studies are needed to prospectively evaluate the impact of geriatric vulnerability parameters at each step of the treatment agenda and the impact of geriatric interventions on patient outcomes.

Management and Survival of Elderly and Very Elderly Patients with Ovarian Cancer: An Age-Stratified Study of 1123 Women from the FRANCOGYN Group

Elderly women with ovarian cancer are often undertreated due to a perception of frailty. We aimed to evaluate the management of young, elderly and very elderly patients and its impact on survival in a retrospective multicenter study of women with ovarian cancer between 2007 to 2015. We included 979 women: 615 women (62.8%) <65 years, 225 (22.6%) 65–74 years, and 139 (14.2%) ≥75 years. Women in the 65–74 years age group were more likely to have serous ovarian cancer (p = 0.048). Patients >65 years had more >IIa FIGO stage: 76% for <65 years, 84% for 65–74 years and 80% for ≥75 years (p = 0.033). Women ≥75 years had less standard procedures (40% (34/84) vs. 59% (104/177) for 65–74 years and 72% (384/530) for <65 years (p < 0.001). Only 9% (13/139) of women ≥75 years had an Aletti score >8 compared with 16% and 22% for the other groups (p < 0.001). More residual disease was found in the two older groups (30%, respectively) than the younger group (20%) (p < 0.05). Women ≥75 years had fewer neoadjuvant/adjuvant cycles than the young and elderly women: 23% ≥75 years received <6 cycles vs. 10% (p = 0.003). Univariate analysis for 3-year Overall Survival showed that age >65 years, FIGO III (HR = 3.702, 95%CI: 2.30–5.95) and IV (HR = 6.318, 95%CI: 3.70–10.77) (p < 0.001), residual disease (HR = 3.226, 95%CI: 2.51–4.15; p < 0.001) and lymph node metastasis (HR = 2.81, 95%CI: 1.91–4.12; p < 0.001) were associated with lower OS. Women >65 years are more likely to have incomplete surgery and more residual disease despite more advanced ovarian cancer. These elements are prognostic factors for women’s survival regardless of age. Specific trials in the elderly would produce evidence-based medicine and guidelines for ovarian cancer management in this population.

Factors associated with surgical morbidity of primary debulking in epithelial ovarian cancer

Objective

Epithelial ovarian cancer (EOC) requires an aggressive surgical approach. The important part of literature on ovarian cancer surgery emphasize residual tumor and survival analyses. Morbidity issue keeps in background. Therefore, we aimed to report on morbidity of cytoreductive surgery for EOC in this study.

Methods

EOC patients who underwent primary debulking were evaluated. Intraoperative and postoperative complications that occurred within 30 days after the surgery and factors that affect morbidity were considered.

Results

The study involved 359 patients. Forty-six intraoperative complications occurred in 42 (11.6%) patients. Advanced stage and cancer antigen level of 125 were independently and significantly associated with operative complications (hazard ratio [HR], 1.66; 95% confidence interval [CI], 1.01–2,73; P=0.044, and HR, 1.47; 95% CI, 1.05–2.06; P=0.025, respectively). The need for intensive care unit admission was significantly higher in patients with intraoperative complications (28.6% vs. 8.8%, P=0.001). Intraoperative and postoperative complication rates were significantly higher in extended surgery than in standard surgery (18.9%vs. 8.5%, P=0.005 and 38.7% vs. 10.9%, P<0.001, respectively). Intraoperative and postoperative transfusion need, hospital stay duration, and chemotherapy start day were also significantly higher in extended surgery than in standard surgery. Hundred postoperative complications occurred in 70 patients. Age, extended surgery, presence of ascites, and presence of operative complications were independently and significantly associated with postoperative complications.

Conclusion

Morbidity of extensive surgical approach should be kept in mind in ovarian cancer surgery aimed at leaving no residual tumor. Patient-based management with an appropriate preoperative evaluation may avoid morbidity of extended/extensive surgical approaches.

[Epithelial ovarian cancer and elderly patients. Article drafted from the French Guidelines in oncology entitled "Initial management of patients with epithelial ovarian cancer" developed by FRANCOGYN, CNGOF, SFOG, GINECO-ARCAGY under the aegis of CNGOF and endorsed by INCa]

In ovarian, tubal and primary peritoneal cancers, older adults have an over-mortality due to more aggressive disease (NP4), surgical and chemotherapy under treatment (NP4) and co-morbidities (NP4). Older age is at higher risk for postoperative morbidity and mortality (NP4). Surgery is more often incomplete in this elderly population (NP4). Older age is a risk factor for lower dose intensity in adjuvant chemotherapy (NP4) and incomplete chemotherapy (NP4). Nevertheless, the benefit of a complete surgery remains identical to that of the younger population (NP2). Preoperative functional assessment identifies patients at risk for postoperative complications (NP4). The perioperative risk depends on three variables, the ASA score, the age and the complexity score of the surgery (NP4). It is recommended to perform cytoreduction surgery in an expert centre (grade C) and on the basis of geriatric expertise analysing functional and physical performance (grade C). The benefit/risk balance of surgery should be assessed on a case-by-case basis for the most at-risk (NP4) populations defined by: (i) age≥80 years, especially if albuminemia≤37g/L; (ii) age≥75 years and FIGO stage IV; (iii) age≥75 years, stage FIGO III and≥1 comorbidity. A comprehensive geriatric assessment is recommended prior to the management of an elderly person with primary ovarian, tubal or peritoneal cancer (grade C). The GVS (Geriatric Vulnerability Score) is used to identify vulnerable elderly patients (NP2). In fit elderly patients, it is recommended to perform intravenous chemotherapy identical to that of younger patients (ie platinum-based dual therapy) (grade B). In vulnerable elderly patients, various adapted chemotherapy regimens have been prospectively evaluated in non-comparative trials, and seem feasible considering specific and nonspecific toxicities: carboplatin monotherapy (NP2), carboplatin AUC2+paclitaxel 60mg/m² 3 weeks/4 (NP2), carboplatin AUC 4-5+paclitaxel 135mg/m²/3 weeks (NP2), carboplatin AUC5/3 weeks+paclitaxel 60mg/m²/week (NP3). In the absence of comparative data, no recommendation can be made in this population. Primary chemotherapy decreases the complexity of the surgical procedure and perioperative morbidity and mortality during interval surgery (NP1). It should be considered after 70 years in cases of comorbidities and/or peritoneal carcinomatosis sufficient for complex initial surgery (NP4).

Management of endometrial, ovarian and cervical cancer in the elderly: current approach to a challenging condition

PURPOSE

Gynaecological cancer management in older people represents a current challenge. Therefore, in the present paper, we aimed to gather all the evidence reported in the literature concerning gynecological cancers in the elderly, illustrating the state of art and the future perspectives.

METHODS

We searched MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials, IBECS, BIOSIS, Web of Science, SCOPUS and Grey literature (Google Scholar; British Library) from January 1952 to May 2017, using the terms "ovarian cancer", "endometrial cancer", "cervical cancer", "gynecological cancers" combined with 'elderly', 'cancer', 'clinical trial' and 'geriatric assessment'.

RESULTS

The search identified 81 citations, of which 65 were potentially relevant after initial evaluation and met the criteria for inclusion and were analyzed. We divided all included studies into three different issue: "Endometrial cancer", "Ovarian cancer" and "Cervical cancer".

CONCLUSIONS

The present literature review shows that, in spite of the higher burden of comorbidities, elderly patients can also benefit from standard treatment to manage their gynecological cancers. It is important to overcome the common habit of undertreating the elderly patients because they are more fragile and with a lower life expectancy than their younger counterpart. Further trials with elderly women are warranted.

Prognostic value of preoperative lymphocyte-monocyte ratio in elderly patients with advanced epithelial ovarian cancer

Objective

To investigate the prognostic significance of preoperative lymphocyte-monocyte ratio (LMR) in elderly patients with advanced epithelial ovarian cancer (EOC) receiving primary cytoreductive surgery and adjuvant platinum-based chemotherapy.

Methods

A total of 42 elderly patients (≥65 years) diagnosed with EOC who are receiving primary cytoreductive surgery and adjuvant platinum-based chemotherapy from 2009 to 2012 was included. LMR was calculated from complete blood cell count sampled before operation. Receiver operating characteristic (ROC) curves were used to calculate optimal cut-off values for LMR. Prognostic significance with respect to overall survival (OS) and progression-free survival (PFS) were determined using log-rank test and Cox regression analysis.

Results

The optimized LMR cut-off value determined by ROC curve analysis was 3.63 for PFS and OS. The high LMR group (LMR ≥3.63) was found to be significantly more associated with optimal debulking (P=0.045) and platinum response (P=0.018) than the low LMR group. In addition, Kaplan-Meier analysis revealed the LMR-high group was significantly more associated with high PFS and OS rates (P=0.023 and P=0.033, respectively), and univariate analysis revealed that a high LMR, histology type, and optimal debulking and platinum responses were significantly associated with prolonged PFS and OS. However, subsequent Cox multivariate analysis showed only optimal debulking and platinum response were independent prognostic factors of PFS or OS.

Conclusion

This study suggests that LMR might be associated with treatment and survival outcomes in elderly patients with EOC receiving standard oncology treatment.

Evaluation of the efficacy and toxicity profile associated with intraperitoneal chemotherapy use in older women

OBJECTIVE

Intraperitoneal (IP) chemotherapy (CT) for treatment of epithelial ovarian cancer (EOC) has been shown to provide a substantial OS advantage. This study aims to compare the toxicity and benefits of IP CT in patients ≥70 with those <70.

METHODS

We performed a single institution retrospective review of patients diagnosed with Stage IIA-IIIC EOC from 2000 to 2013 who received IP CT. Clinicopathologic characteristics were extracted, and survival was calculated.

RESULTS

133 patients were included with 100 pts. <70years old and 33 pts. ≥70years old. Clinical trial enrollment was similar despite age. In trial enrolled patients, older patients received statistically fewer cycles of therapy (6.4 vs 5.8, p=0.002) but had similar dose delays (0.9 vs 0.7, p=0.72), and modifications (0.9 vs 0.36, p=0.11). Median PFS (27 vs 31months) and OS (71 and 62months) were not statistically different. Grade 3/4 neutropenia was significantly worse in the older patients (82% vs 100%, p=0.04). Neuropathy grade ≥2 and other non-hematologic toxicities were not different between age groups.

CONCLUSIONS

Despite completing fewer cycles of IP CT, older EOC patients had comparable survival to younger patients. The population of older patients receiving IP CT in this study were on clinical trial and likely to be heartier than the general older population. IP CT appears well tolerated and effective among select older patients and is likely under-utilized outside of clinical trials.

Prediction of Optimal Cytoreductive Surgery of Serous Ovarian Cancer With Gene Expression Data

OBJECTIVES

Cytoreductive surgery is the cornerstone of ovarian cancer (OVCA) treatment. Detractors of initial maximal surgical effort argue that aggressive tumor biology will dictate survival, not the surgical effort. We investigated the role of biology in achieving optimal cytoreduction in serous OVCA using microarray gene expression analysis.

METHODS

For the initial model, we used a gene expression signature from a microarray expression analysis of 124 women with serous OVCA, defining optimal cytoreduction as removal of all disease greater than 1 cm (with 64 women having optimal and 60 suboptimal cytoreduction). We then applied this model to 2 independent data sets: the Australian Ovarian Cancer Study (AOCS; 190 samples) and The Cancer Genome Atlas (TCGA; 468 samples). We performed a second analysis, defining optimal cytoreduction as removal of all disease to microscopic residual, using data from AOCS to create the gene signature and validating results in TCGA data set.

RESULTS

Of the 12,718 genes included in the initial analysis, 58 predicted accuracy of cytoreductive surgery 69% of the time (P = 0.005). The performance of this classifier, measured by the area under the receiver operating characteristic curve, was 73%. When applied to TCGA and AOCS, accuracy was 56% (P = 0.16) and 62% (P = 0.01), respectively, with performance at 57% and 65%, respectively. In the second analysis, 220 genes predicted accuracy of cytoreductive surgery in the AOCS set 74% of the time, with performance of 73%. When these results were validated in TCGA set, accuracy was 57% (P = 0.31) and performance was at 62%.

CONCLUSION

Gene expression data, used as a proxy of tumor biology, do not predict accurately nor consistently the ability to perform optimal cytoreductive surgery. Other factors, including surgical effort, may also explain part of the model. Additional studies integrating more biological and clinical data may improve the prediction model.

The Application and Outcome of Standard of Care Treatment in Elderly Women with Ovarian Cancer: A Literature Review over the Last 10 Years

The rising number and increasing longevity of the elderly population calls for improvements and potentially a more personalized approach to the treatment of cancer in this group. Elderly patients frequently present with a number of comorbidities, complicating surgery and chemotherapy tolerability. In the case of ovarian cancer, elderly women present with more advanced disease, making the issue of providing adequate treatment without significant morbidity critical. Most studies support the application of standard of care treatment to elderly women with ovarian cancer, yet it seems to be offered less frequently in the elderly. The objective of this review is to examine the application and outcome of standard of care treatment in elderly women with ovarian cancer. The aim is to ultimately improve the approach to treatment in this group.

Treating gynecologic malignancies in elderly patients

AIM

To determine the relative benefits of full and partial treatment for gynecologic malignancies in elderly patients.

METHODS

A retrospective cohort study of all consecutive patients (n=169) aged 79 and older (median age 82 y; range, 79 to 94 y), diagnosed between 1971 and 2007 with various types of gynecologic malignancies (endometrial, 52%; ovarian, 26%; vulvar, 11%; cervical, 5%; other, 6%) was conducted. Stages were I to II (47%), III to IV (35.5%), and unknown (17.5%). Major comorbidities were hypertension (51%), diabetes (17%), cardiac diseases (34%), and other malignancy (12%). Regardless of age or chronic illnesses, patients were grouped on the basis of having been treated optimally (100 patients; 59.2%), defined as the accepted standard for each diagnosis and stage including surgery and adjuvant radiation or chemotherapy as indicated; or suboptimally (69 patients; 40.8%), that is, no or only partial treatment. Kaplan-Meier survival analysis and Cox proportional hazard models, univariate and multivariable were conducted.

RESULTS

For all patients with suboptimal treatment, the age-and-stage-adjusted hazard ratio for death was 1.76 (95% CI, 1.203-2.570; P=0.004) compared with optimal treatment. Age-adjusted hazard ratio was 2.15 (95% CI, 1.127-4.114; P=0.02) and 2.3 (95% CI, 1.415-3.779; P=0.001) for ovarian and endometrial cancer patients, respectively. Age-adjusted and stage-adjusted hazard ratio was 2.8 (95% CI, 1.099-5.157; P=0.028) and 1.53 (95% CI, 0.867-2.702; P=0.1420) for ovarian and endometrial cancer patients, respectively.

CONCLUSIONS

Optimal treatment in patients with gynecologic malignancies evidently improves survival in elderly patients at any age, and in patients with ovarian cancer at any stage. Regardless of chronological age, the aim should be to deliver optimal treatment.

Hypofractionated radiation therapy for treatment of bladder carcinoma in patients aged 90 years and more: A new paradigm to be explored?

INTRODUCTION

There are only scarce data on the optimal management of patients who present with a bladder carcinoma and who are aged 90 years and older.

PATIENTS AND METHODS

We retrospectively reviewed records from radiotherapy departments from two university hospitals, two private centers and one public center to identify patients who underwent radiotherapy for bladder cancer over the past decade and who were aged 90 years or older. From 2003 to 2013, 14 patients aged 90 years or older receiving RT for bladder malignant tumors were identified.

RESULTS

Mean age was 92.7 years. Ten patients (71 %) had a general health status altered (PS 2-3) at the beginning of RT. A total of 14 RT courses were delivered, including six treatments (43 %) with curative intent and eight treatments (57 %) with palliative intent. Palliative intent mainly encompassed hemostatic RT (36 %). At last follow-up, two patients (14 %) experienced complete response, one patient (7 %) experienced partial response, three patients (21 %) had their disease stable, and three patients (21 %) experienced tumor progression, of whom two patients with the progression of symptoms. There was no reported high-grade acute local toxicity in 14 patients (100 %). One patient experienced delayed grade 2 toxicity with pain and lower urinary tract symptoms. At last follow-up, seven patients (50 %) were deceased. Cancer was the cause of death for five patients.

CONCLUSION

Hypofractionated radiotherapy remains feasible for nonagenarians with bladder cancer. Further investigations including analysis of geriatric comorbidities and impact of treatments on quality of life should be conducted.

Breast and ovarian cancer in the older woman

Nearly half of all women diagnosed with breast or ovarian cancer are age 65 years or older with the number of women diagnosed expected to increase as the population ages and life expectancy improves. Older women are less likely to be offered standard cancer treatments, are more likely to develop higher toxicity, and have higher mortality. Chronologic age should not be the only factor used for making treatment decisions. Functional dependence, organ function, comorbidity, polypharmacy, social support, cognitive and/or psychosocial factors, overall life expectancy, and patient's goals of care are equally vital and should be assessed before and during treatment. In this review, current evidence and treatment guidelines for older women with breast or ovarian cancer are outlined.

Portrait, treatment choices and management of breast cancer in nonagenarians: an ongoing challenge

There are only scarce data on the management of nonagenarians with breast cancer, and more particularly on the place of radiation therapy (RT). We report a retrospective study on patients aged 90 years old or older, with breast cancer, receiving RT. Records from RT departments from five institutions were reviewed to identify patients 90 years old of age and older undergoing RT over past decade for breast cancer. Tumors' characteristics were examined, as well treatment specificities and treatment intent. 44 patients receiving RT courses were identified, mean age 92 years. Treatment was given with curative and palliative intent in 72.7% and 27.3% respectively. Factors associated with a curative treatment were performance status (PS), place of life, previous surgery, and tumor stage. Median total prescribed dose was 40 Gy (23-66). Hypo fractionation was used in 77%. Most toxicities were mild to moderate. RT could not be completed in 1 patient (2.3%). No long-term toxicity was reported. Among 31 patients analyzable for effectiveness, 24 patients (77.4%) had their diseased controlled until last follow-up, including 17 patients (54.8%) experiencing complete response. At last follow-up, 4 patients (12.9%) were deceased, cancer being cause of death for two of them. The study shows that breast/chest RT is feasible in nonagenarians. Although the definitive benefit of RT could not be addressed here, hypofractionated therapy allowed a good local control with acceptable side effects.

Risk-scoring model for prediction of non-home discharge in epithelial ovarian cancer patients

BACKGROUND

Identification of preoperative factors predictive of non-home discharge after surgery for epithelial ovarian cancer (EOC) may aid counseling and optimize discharge planning. We aimed to determine the association between preoperative risk factors and non-home discharge.

STUDY DESIGN

Patients who underwent primary surgery for EOC at Mayo Clinic between January 2, 2003 and December 29, 2008 were included. Demographic, preoperative, and intraoperative factors were retrospectively abstracted. Logistic regression models were fit to identify preoperative factors associated with non-home discharge. Multivariable models were developed using stepwise and backward variable selection. A risk-scoring system was developed for use in preoperative counseling.

RESULTS

Within our cohort of 587 EOC patients, 12.8% were not discharged home (61 went to a skilled nursing facility, 1 to a rehabilitation facility, 1 to hospice, and there were 12 in-hospital deaths). Median length of stay was 7 days (interquartile range [IQR] 5, 10 days) for patients dismissed home compared with 11 days (IQR 7, 17 days) for those with non-home dismissals (p < 0.001). In multivariable analyses, patients with advanced age (odds ratio [OR] 3.75 95% CI [2.57, 5.48], p < 0.001), worse Eastern Cooperative Oncology Group (ECOG) performance status (OR 0.92 [95% CI 0.43, 1.97] for ECOG performance status 1 vs 0 and OR 5.40 (95% CI 2.42, 12.03) for score of 2+ vs 0; p < 0.001), greater American Society of Anesthesiologists (ASA) score (OR 2.03 [95% CI 1.02, 4.04] for score ≥3 vs < 3, p = 0.04), and higher CA-125 (OR 1.28 [95% CI 1.12, 1.46], p < 0.001) were less likely to be discharged home. The unbiased estimate of the c-index was excellent at 0.88, and the model had excellent calibration.

CONCLUSIONS

Identification of preoperative factors associated with non-home discharge can assist patient counseling and postoperative disposition planning.

Effect of radical cytoreductive surgery on omission and delay of chemotherapy for advanced-stage ovarian cancer

OBJECTIVE

Cytoreductive surgery is associated with extensive morbidity and may delay chemotherapy. We examined the associations among cytoreduction, perioperative complications, and delay or omission of chemotherapy.

METHODS

Women aged 65 years or older with stage III-IV ovarian cancer who were treated with surgery from 1991-2005 and recorded in the Surveillance, Epidemiology, and End Results-Medicare database were examined. We estimated the influence of extended cytoreduction as well as the occurrence of major perioperative complications on receipt and timing of chemotherapy and survival.

RESULTS

Among 3,991 patients, 479 (12%) failed to receive chemotherapy. Of those treated with chemotherapy, 2,527 (72%) initiated treatment within 6 weeks of surgery, 838 (24%) within 6-12 weeks, and 147 (4%) more than 12 weeks after surgery. In a multivariable model, older patients, those with comorbidities, mucinous tumors, and stage IV neoplasms were more likely not to receive chemotherapy (P<.05). Extended cytoreduction and the occurrence of postoperative complications were not associated with omission of chemotherapy but were associated with chemotherapy delay. For every 14 patients who underwent one extended procedure and for every 13 who had two extended procedures, one patient had a delay in receipt of chemotherapy. For every 14 patients who had one complication and for every four who had two complications, one patient had a delay in receipt of chemotherapy. The occurrence of more than two perioperative complications (hazard ratio 1.31, 95% confidence interval [CI] 1.15-1.49) and initiation of chemotherapy more than 12 weeks after surgery (hazard ratio 1.32, 95% CI 1.07-1.64) were associated with decreased survival.

CONCLUSION

Extended cytoreductive surgery and perioperative complications significantly delay initiation but do not increase the chance of omission of chemotherapy for women with ovarian cancer.

Elderly and very elderly advanced ovarian cancer patients: does the age influence the surgical management?

BACKGROUND

To examine the surgical treatment and clinical outcome of elderly and very elderly advanced epithelial ovarian cancer patients.

METHODS

We retrospectively analyzed FIGO stage IIIC-IV ovarian cancer patients, divided in elderly (Group A, >65 and <75 years) and very elderly patients (Group B, ≥ 75 years) treated by primary debulking surgery (PDS) or by interval debulking surgery (IDS) at the Catholic University at Rome and Campobasso, Italy.

RESULTS

164 patients were included: 123 (Group A) and 41 (Group B). Complete cytoreduction was achieved in 60 patients (60.6%) in Group A and in 20 patients (62.5%) in Group B (p = 0.75). In the remaining cases, optimal cytoreduction was performed (39 cases (39.4%) in Group A and 12 (37.5%) in Group B; p = 0.75). In Group A complete/optimal debulking was achieved in 53 patients (53.5%) at PDS and in 46 patients (46.5%) at IDS (p = 0.55). In the Group B a higher rate of patients was debulked at IDS with respect to PDS (10 (31.3%) vs. 22 patients (68.7%); p = 0.02). In Group A patients debulked at PDS showed better DFS (p = 0.007) and OS (p = 0.003) with respect to patients submitted to successful IDS, whereas in group B we did not observed any survival difference according to time of cytoreduction.

CONCLUSIONS

Our data suggest that elderly and very elderly patients may tolerate radical and ultra-radical surgery. These patients should be managed in a gynecologic oncology unit, with prudent but complete approach.

Evaluation of prevalent and incident ovarian cancer co-morbidity

BACKGROUND

The peak in incidence of ovarian cancer occurs around 65 years and concurrent increasing risk by age for a number of diseases strongly influence treatment and prognosis. The aim was to explore prevalence and incidence of co-morbidity in ovarian cancer patients compared with the general population.

METHODS

The study population was patients with ovarian cancer in Sweden 1993-2006 (n=11 139) and five controls per case (n=55 687). Co-morbidity from 1987 to 2006 was obtained from the Swedish Patient Register. Prevalent data were analysed with logistic regression and incident data with Cox proportional hazards models.

RESULTS

Women developing ovarian cancer did not have higher overall morbidity than other women earlier than 3 months preceding cancer diagnosis. However, at time of diagnosis 11 of 13 prevalent diagnosis groups were more common among ovarian cancer patients compared with controls. The incidence of many common diagnoses was increased several years following the ovarian cancer and the most common diagnoses during the follow-up period were thromboembolism, haematologic and gastrointestinal complications.

CONCLUSION

Women developing ovarian cancer do not have higher overall morbidity the years preceding cancer diagnosis. The incidence of many common diagnoses was increased several years following the ovarian cancer. It is crucial to consider time between co-morbidity and cancer diagnosis to understand and interpret associations.

Management of the Elderly Patient With Gynecologic Cancer: Report of the 2011 Workshop in Geriatric Gynecologic Oncology

Abstract

Reflecting the worldwide aging trend and close association of aging with cancer, geriatric oncology is now growing beyond its pioneer years. Nevertheless, geriatric oncology in the gynecologic field is in the beginning stage; indeed, there is no geriatric specialist who is trained in this particular field of gynecologic oncology. Therefore, we held the first workshop in geriatric gynecologic oncology. In this review, we summarize what we discussed at the workshop and provide evidence-based recommendations for the diagnosis and treatment of gynecologic cancer in elderly individuals.

Defining the limits of radical cytoreductive surgery for ovarian cancer

OBJECTIVE

Despite significant morbidity, surgical cytoreduction is the standard of care for ovarian cancer. We examined the outcomes of cytoreductive surgery to determine if there are groups of patients in which the morbidity is so substantial that alternate treatment strategies are warranted.

METHODS

The Nationwide Inpatient Sample was used to identify women who underwent surgery for ovarian cancer from 1998 to 2007. The effect of age, number of radical procedures performed, and clinical characteristics on morbidity and mortality were examined.

RESULTS

A total of 28,651 women were identified. The complication rates increased with age from 17.1% in those <50 years of age to 29.7% in women age 70-79 and to 31.5% in those ≥ 80 (p<0.05). The number of extended procedures performed was also a predictor of morbidity; complications increased from 20.4% for women with 0 procedures to 34.0% for 1 and 44.0% for ≥ 2 procedures (p<0.0001). In multivariable analysis age, comorbidity, and the number of procedures performed were the strongest predictors of outcome. The morbidity associated with additional procedures was greatest in the elderly. Medical complications in women <50 years of age occurred in 10.2% of those who underwent 0 radical procedures vs. 23.7% in those who underwent 2 or more procedures. For women ≥ 80 years, complications were noted in 18.3% for 0 procedures, and 33.3% for 2 or more procedures.

CONCLUSION

The morbidity of cytoreduction is greatest in elderly women where the effects of age and the number of radical procedures performed have an additive effect on complication rates.

Bilateral ovarian teratoma complicated with carcinosarcoma in a 68 year old woman: a case report

Background

Composing of less than 1% of all ovarian cancers, immature teratoma is a malignancy that mainly affects the young, and they present with advanced disease. The treatment of immature teratoma is conservative primary surgery usually involving unilateral salpingo-oophorectomy followed by combination chemotherapy.

Case presentation

Here we present a case of a 68 year old woman with bilateral ovarian teratoma complicated with carcinosarcoma. The patient was diagnosed as FIGO stage IIIC. She underwent neoadjuvant chemotherapy and interval cytoreduction followed by optimal cytoreduction. The post operative management strategies and gynaecological follow up studies revealed no evidence of regional or distant metastasis.

Conclusion

Thus the choice of initial treatment should be decided in a selective fashion depending on various prognostic factors in order to increase the survival of the patients.

Clinical Trials and Treatment of the Elderly Diagnosed With Ovarian Cancer

Elderly patients are more commonly diagnosed with advanced ovarian cancer and represent a growing proportion of all ovarian cancer cases. Despite this, the elderly have historically been underrepresented in clinical trials. Because clinical trials form the basis for most treatment guidelines and the elderly have been, to date, largely excluded from this process, little is known about the appropriate assessment and treatment of elderly ovarian cancer patients. Recognizing this knowledge deficit and the pressing need to correct it, this article aimed to summarize existing data and identify future areas of research focus.

Feasibility and safety of extensive upper abdominal surgery in elderly patients with advanced epithelial ovarian cancer

We performed a retrospective study to evaluate the feasibility and safety of extensive upper abdominal surgery (EUAS) in elderly (>/=65 yr) patients with advanced ovarian cancer. Records of patients with advanced epithelial ovarian cancer who received surgery at our institution between January 2001 and June 2005 were reviewed. A total of 137 patients including 32 (20.9%) elderly patients were identified. Co-morbidities were present in 37.5% of the elderly patients. Optimal cytoreduction was feasible in 87.5% of the elderly while 95.2% of young patients were optimally debulked (P=0.237). Among 77 patients who received one or more EUAS procedures, 16 (20.8%) were elderly. Within the cohort, the complication profile was not significantly different between the young and the elderly, except for pleural effusion and pneumothorax (P=0.028). Elderly patients who received 2 or more EUAS procedures, when compared to those 1 or less EUAS procedure, had significantly longer operation times (P=0.009), greater blood loss (P=0.002) and more intraoperative transfusions (P=0.030). EUAS procedures are feasible in elderly patients with good general condition. However, cautious peri-operative care should be given to this group because of their vulnerability to pulmonary complications and multiple EUAS procedures.

Primary chemotherapy patterns for ovarian cancer treatment in Japan

AIMS

Evidence-based clinical practices can improve patient outcomes, especially in the area of chemotherapy. In Japan, it is not known how well physicians adhere to evidence-based chemotherapy guidelines. This study aimed to assess physician compliance with national guidelines for ovarian cancer primary chemotherapy in Japan.

METHODS

Using an administrative database, we analyzed 209 cases of surgical laparotomy without neoadjuvant chemotherapy as the primary intervention for adnexal cancer. Cases were identified across seven teaching hospitals between 2003 and 2006.

RESULTS

Of the 136 patients receiving inpatient chemotherapy, 101 cases (74%) were treated with platinum-taxane therapy. In five hospitals, platinum-taxane therapy was used in more than 75% of patients, compared to 56% and 32% in the other two hospitals, respectively. The proportion of patients receiving paclitaxel and carboplatin concomitant therapy (TC therapy) was 67%, although significant variation was noted between hospitals (range 32% to 94%, P < 0.001). Of the 91 patients receiving TC therapy, 59 (65%) were given full-dose monthly regimens, while 32 cases (35%) were treated with divided doses weekly. Weekly TC therapy was more frequently provided in hospitals with a low volume of patients receiving TC therapy. Patients under the age of 65 receiving inpatient chemotherapy were more likely to receive full-dose regimens than patients 65 or older (68% vs 43%, P = 0.005). Publication of national treatment guidelines did not appear to substantially impact chemotherapy practice patterns.

CONCLUSIONS

Adherence to standardized chemotherapy was comparable to rates in European countries, although rates among hospitals differed significantly. Elderly patients were more likely to receive divided-dose regimens.

Ovarian cancer in the elderly: outcomes with neoadjuvant chemotherapy or primary cytoreduction

BACKGROUND

Recent studies have suggested inferior outcomes for elderly women with ovarian cancer. Our goal was to evaluate neoadjuvant chemotherapy versus primary cytoreduction in elderly women.

METHODS

A retrospective chart review was performed for women aged 65+ diagnosed with ovarian cancer at our institution between 1997 and 2007. Univariate and multivariate logistic regression models were used to evaluate complication rates. Survival was evaluated with Cox regression and the Kaplan-Meier method.

RESULTS

One hundred seventy-five patients were identified, 34 (19%) of whom were aged 80+. Those aged 65-79 and those 80+ received neoadjuvant chemotherapy with equal frequency (19% vs. 21%, p=0.92). Treatment with neoadjuvant chemotherapy was associated with odds ratios of 0.80 (95% CI 0.37-1.75) for surgical complications and 0.79 (95% CI 0.33-1.90) for chemotherapeutic complications. In those aged 80+, the frequency of surgical complications (OR 1.01, p=0.62) and chemotherapeutic complications (OR 1.04, p=0.78) did not differ compared to younger patients. Overall survival did not differ based on initial treatment regimen, with 34 months in the primary surgery group and 29 months in the neoadjuvant chemotherapy group (p=0.65). The median disease specific survival for those aged 65-79 was 35 months, and 24 months in those aged 80+ (p=0.15). Post-operative mortality for patients aged 80+ was zero.

CONCLUSIONS

In our patient population, those aged 80+ have similar surgical and chemotherapy-related complication rates and comparable survival to those aged 65-79. The choice of initial treatment modality does not appear to impact survival when the decision is made in a selective fashion.

Prediction of 30-day morbidity after primary cytoreductive surgery for advanced stage ovarian cancer

OBJECTIVE

Treatment in advanced stage epithelial ovarian cancer (EOC) is based on primary cytoreductive surgery followed by platinum-based chemotherapy. Successful cytoreduction to minimal residual tumour burden is the most important determinant of prognosis. However, extensive surgical procedures to achieve maximal debulking are inevitably associated with postoperative morbidity and mortality. The objective of this study is to determine predictors of 30-day morbidity after primary cytoreductive surgery for advanced stage EOC.

METHODS

All patients in the South Western part of the Netherlands who underwent primary cytoreductive surgery for advanced stage EOC between January 2004 and December 2007 were identified from the Rotterdam Cancer Registry database. All peri- and postoperative complications within 30 days after surgery were registered and classified according to the definitions of the National Surgical Quality Improvement Programme (NSQIP). To investigate independent predictors of 30-day morbidity, a Cox proportional hazards model with backward stepwise elimination was utilised. The identified predictors were entered into a nomogram.

RESULTS

Two hundred and ninety-three patients entered the study protocol. Optimal cytoreduction was achieved in 136 (46%) patients. 30-day morbidity was seen in 99 (34%) patients. Postoperative morbidity could be predicted by age (P=0.007; odds ratio [OR] 1.034), WHO performance status (P=0.046; OR 1.757), extent of surgery (P=0.1308; OR=2.101), and operative time (P=0.017; OR 1.007) with an optimism corrected c-statistic of 0.68.

CONCLUSION

30-day morbidity could be predicted by age, WHO performance status, operative time and extent of surgery. The generated nomogram could be valuable for predicting operative risk in the individual patient.

Postoperative mortality after primary cytoreductive surgery for advanced stage epithelial ovarian cancer: a systematic review

OBJECTIVE

Accurate estimation of the risk of postoperative mortality (POM) is essential for the decision whether or not to perform cytoreductive surgery in a patient with advanced stage ovarian cancer. To ascertain modern reference figures, a systematic review of studies reporting POM after primary cytoreductive surgery for advanced stage epithelial ovarian cancer (EOC) was performed.

MATERIALS AND METHODS

A Medline search was performed to retrieve papers on primary cytoreductive surgery for advanced stage EOC. Twenty-three papers met the inclusion criteria and were reviewed.

RESULTS

According to population-based studies, POM after primary cytoreductive surgery for EOC is 3.7% on average. Single centre studies report an average rate of 2.5%. The overall mean POM is 2.8%. POM is more frequent for elderly women and after extensive procedures. Accurate information on age-specific and procedure-specific rates could not be obtained.

CONCLUSION

POM rates after surgery for EOC are satisfactorily low. There is a clear need for reliable reference figures for mortality after debulking surgery in the elderly.

Relationship among surgical complexity, short-term morbidity, and overall survival in primary surgery for advanced ovarian cancer

BACKGROUND

Advanced ovarian cancer (OC) is associated with impaired performance status and comorbidities for many patients. These factors have an impact on the decision to perform extended surgical cytoreduction. However, the trade-off between short-term morbidity and overall survival is complex, and few data are available analyzing the combined effects of these variables.

PURPOSE

The purpose of the study was to evaluate the impact of patients' age and American Society of Anesthesiologists (ASA) and surgical complexity score (SCS) on short-term morbidity and overall survival.

STUDY DESIGN

Presurgical patient characteristics, surgical procedures performed, and outcomes were assessed in a cohort of consecutive primary OC patients. An SCS from 1 to 3 was developed to adjust for the extent of surgery (simple to complex, respectively). Primary outcomes were 30 day major morbidity (sepsis, thromboembolic, cardiac, or reoperation), 3 month mortality, and overall survival (OS).

RESULTS

Two hundred nineteen consecutive patients with stage IIIC-IV OC were included. We observed a correlation between ASA and both short-term morbidity (P = .006) and 3 month mortality (P = .006). Age was independently associated with both short-term morbidity (P = .010) and 3 month mortality (P = .005). SCS correlated directly with morbidity (P < .001) but was not correlated with mortality (P = .266). The independent predictors of morbidity (ASA, age, and SCS) were used to develop risk prediction categories: risk of expected complications ranged from 2.5% to 67.6%, depending on category. Despite the increased risk of complications, however, more complex surgery carried a survival benefit in all the risk groups, owing to the observation that residual disease (RD) and SCS held a prognostic significance independent of age and ASA (P < .001 and P = .001, respectively).

CONCLUSION

Because of the survival benefit from lower RD, a less aggressive surgical effort results in poorer OS. However, the risk of complications are substantial for complex surgeries in the highest-risk patients: risk stratification should be used to help plan perioperative care and consider optimal treatment planning.

Predictors of extended intensive care unit resource utilization following surgery for ovarian cancer

OBJECTIVE

To identify perioperative variables associated with length of stay in the surgical intensive care unit (SICU), and overall cost of hospitalization in order to optimize resource utilization among patients undergoing surgery for ovarian cancer.

METHODS

A retrospective analysis of patients admitted to the SICU immediately after surgery for ovarian cancer between 1/1/94 and 6/30/04 was performed. Patients admitted to the SICU were categorized in two groups. Those admitted for < 48 h were compared patients requiring a SICU stay > or = 48 h. Perioperative variables were compared across the two groups by univariate and multivariate logistic regression analysis.

RESULTS

A total of 95 patients were admitted to the SICU immediately after surgical management for ovarian cancer, with 57% requiring a stay > or = 48 h. Patient age = 63 years was associated with an increase risk of admission to the SICU for > or = 48 h (OR: 5.9, 95% CI: 1.72-20.50, p=0.005). Patients with administration of > or = 5 l of crystalloid solution during surgery were 8 times more likely to have prolonged admission to the SICU (95% CI: 2.34-27.57, p=0.001). Furthermore, a preoperative serum albumin level > or = 3.5 g/dl was associated with a reduction in the risk of prolonged admission to the SICU (OR: 0.23, 95% CI: 0.07-0.77, p=0.02). The average cost of hospitalization per patient was $33,086. Cost of hospital care was strongly associated with SICU length of stay (p=0.005).

CONCLUSION

Extensive fluid resuscitation during surgery, poor nutritional status, and > or = 63 years are associated with a prolonged postoperative SICU stay. These data may facilitate a reduction in unnecessary ICU admissions for patients without these risk factors and thereby optimize resource utilization following surgery for ovarian cancer.

Pathologic findings and outcomes for octogenarians presenting with uterine malignancy

OBJECTIVE

We evaluated prognostic, demographic and outcome data for patients>80 years old with uterine cancer (UC).

METHODS

A retrospective review of clinical records was performed. Categorical data were compared using Fisher's exact test and Kaplan-Meier for survival data.

RESULTS

Sixty-five patients were identified with a mean age of 84 and BMI 27. Sixty-five percent of patients had medical co-morbidities. Forty-two (65%) were Stage I; 10 (15%) were Stage II; 8 (12%) were Stage III; and 5 (8%) were Stage IV. Stage I patients included those identified via hysterectomy with lymph nodes (LND) (30) or clinical impression (12). Comparing clinically Stage I UC to those with LND, the clinical group was older (86 vs. 83; p=0.01) and tended to have more medical co-morbidity (89% vs. 63%; p=0.14). Two-year overall survival (OS) among unstaged vs. staged patients was 62% vs. 77%; p=0.11. Among staged patients with Stage I UC, 21 (70%) met high intermediate risk (HIR) criteria per GOG 99 and 90% received no adjuvant therapy. Three patients (16%) recurred with 1 (5%) locoregional recurrence. Two-year OS is 77%.

CONCLUSION

Elderly patients with UC have features associated with extrauterine spread. Both clinically and surgically staged Stage I patients had excellent OS at 2 years despite no adjuvant therapy. Prevalent medical co-morbidities may impact survival more than recurrence risk. The 23% recurrence rate among HIR patients in GOG 99 was not observed in our data, suggesting that observation for elderly Stage I patients is acceptable.

Feasibility, toxicity and quality of life of first-line chemotherapy with platinum/paclitaxel in elderly patients aged >or=70 years with advanced ovarian cancer--a study by the AGO OVAR Germany

BACKGROUND

The purpose of the study was to evaluate first-line platinum/paclitaxel (Taxol) under phase III trial conditions in ovarian cancer (OC) patients aged >or=70 years.

PATIENTS AND METHODS

Phase III results of 779 patients with OC International Federation of Gynecology and Obstetrics (FIGO) stage IIB/IV treated with cisplatin/paclitaxel versus carboplatin/paclitaxel were retrospectively analyzed according to feasibility, toxicity (National Cancer Institute Common Toxicity Criteria) and quality of life (QoL) [European Organization for Research and Treatment of Cancer QoL questionnaire (EORTC QLQ-C30)] in patients aged <70 or >or=70 years.

RESULTS

One hundred and three (13%) patients were aged >or=70 years. Patient characteristics (<70 versus >or=70 years) showed significant differences with regard to Eastern Cooperative Oncology Group performance status, residual disease and constitutional factors but not to FIGO stage, histology or grading. Elderly patients received 98%, 100% and 96% of the recommended paclitaxel, carboplatin and cisplatin dose, respectively, per cycle. Early discontinuation was more frequent in elderly, although QoL, nonhematological and hematological toxicity were comparable between elderly and younger patients, except for febrile neutropenia (5% versus <1%, P = 0.005). There were no significant differences with regard to cycle delays, dose reductions or the use of granulocyte colony-stimulating factor and antibiotics.

CONCLUSION

Platinum/paclitaxel appeared to be feasible and tolerable in elderly patients under clinical trial conditions, but there seems to be a different investigators' estimation of toxicity and less intention to maintain trial treatment in elderly.

Predictors of surgical outcome and survival among elderly women diagnosed with ovarian and primary peritoneal cancer

OBJECTIVE

To identify perioperative variables that will predict surgical outcome and survival among elderly women diagnosed with ovarian and primary peritoneal cancer.

METHODS

A retrospective review of 78 women>or=75 years treated for ovarian and primary peritoneal cancer from 1/1/90 to 06/30/04 was performed. Patients were categorized in two groups based on optimal versus suboptimal cytoreductive surgery. Perioperative variables were compared across the two groups by univariate and multivariate logistic regression analysis to evaluate the impact on survival.

RESULTS

The median age at the time of diagnosis was 79.3 years. Overall, 50% of the patients underwent optimal cytoreductive surgery. Patients with low perioperative serum albumin levels were associated with a 2.4-fold increased risk of suboptimal cytoreductive surgery (95% CI 1.02-5.88, p=0.04). Median survival of patients that underwent cytoreductive surgery was 19 months. As expected, survival analysis showed that patients with suboptimal cytoreductive surgery had a lower survival (median=17 months) than patients with optimal surgery (median=62 months, p=0.00). Patients>or=80 years were associated with a nearly 2-fold increase in the risk of mortality (95% CI 1.05-3.54, p=0.03), while albumin levels of >or=3.7 g/dl were associated with a 40% reduction in risk of mortality (95% CI 0.41-0.89, p=0.01).

CONCLUSIONS

Optimal cytoreductive surgery is feasible in many elderly patients. Women>or=80 years and with poor nutritional status are associated with a poor survival outcome. Perioperative variables such as these can be used to identify the elderly patients that are most likely to be suboptimally cytoreduced and thus have a dismal survival outcome.

Surgical care of elderly women with ovarian cancer: A population-based perspective

OBJECTIVE

To characterize the primary surgical care and short-term outcomes for ovarian cancer in women aged 80 years and older compared to women younger than 80 years.

METHODS

A statewide hospital discharge database was used to identify women undergoing primary surgery for ovarian cancer from 1990 to 2000. Logistic regression models were used to evaluate for significant differences in demographic characteristics and short-term outcomes comparing women aged > or = 80 years with those aged <80 years.

RESULTS

A total of 2417 women were identified; women aged > or = 80 years comprised 7.0% (n = 168) of cases. Compared to younger women, those aged > or = 80 years were significantly more likely to be admitted under emergent conditions (25.6% vs. 14.9%, P < 0.0003) and less likely to undergo surgery at a university hospital (6.6% vs. 18.6%, P = 0.001). Ovarian cancer patients aged > or = 80 years were significantly more likely to have a longer hospital stay (median 10 days vs. 7 days, P < 0.0001) and a higher adjusted cost of hospital related care (median dollar 76,760 vs. dollar 52,649, P < 0.0001). The 30-day mortality rate was 2.3-fold higher for women aged > or = 80 years (5.4% vs. 2.4%, P = 0.036). For women aged > or = 80 years, there was a trend toward a higher risk of peri-operative death among low-volume hospitals (8.8%) compared to high-volume hospitals (3.0%, P = 0.16).

CONCLUSION

Primary surgical care for ovarian cancer in women aged > or = 80 years is associated with utilization of significant health care resources and worse short-term outcomes compared to younger women. Additional research is needed to identify opportunities for improving the cost-effectiveness of care in this population.
