Cervical Cancer Survivorship: Long-term Quality of Life and Social Support

PURPOSE: Surgery, radiotherapy and chemotherapy are the mainstays of cervical cancer treatment. Many patients receive multiple treatment modalities, each with its own long-term effects. Given the high 5 year survival rate for cervical cancer patients, evaluation and improvement of long-term quality of life are essential. METHODS: Pertinent articles were identified through searches of PubMed for literature published from 1993-2014. We summarize quality of life data from long-term follow up studies of cervical cancer patients. We additionally summarize small group interviews of Hispanic and non-Hispanic cervical cancer survivors regarding social support and coping. FINDINGS: Data is varied in terms of the long term impact of treatment on quality of life but consistent in suggesting that patients who receive radiotherapy as part of their treatment have the highest risk of increased long term dysfunction of bladder and bowel, as well as sexual dysfunction and psychosocial consequences. Rigorous investigations regarding long-term consequences of treatment modalities are lacking. IMPLICATIONS: Continued work to improve treatment outcomes and survival should also include a focus on reducing adverse long-term side effects. Providing supportive care during treatment, and evaluating the effects of supportive care, may reduce the prevalence and magnitude of long-term sequelae of cervical cancer, which will in turn improve quality of life and quality of care

Disparities in Adherence to National Comprehensive Cancer Network Treatment Guidelines and Survival for Stage IB–IIA Cervical Cancer in California

ObjectiveTo evaluate the association of sociodemographic and hospital characteristics with adherence to National Comprehensive Cancer Network treatment guidelines for stage IB-IIA cervical cancer and to analyze the relationship between adherent care and survival.MethodsThis is a retrospective population-based cohort study of patients with stage IB-IIA invasive cervical cancer reported to the California Cancer Registry from January 1, 1995, through December 31, 2009. Adherence to National Comprehensive Cancer Network guideline care was defined by year- and stage-appropriate surgical procedures, radiation, and chemotherapy. Multivariate logistic regression, Kaplan-Meier estimate, and Cox proportional hazard models were used to examine associations between patient, tumor, and treatment characteristics and National Comprehensive Cancer Network guideline adherence and cervical cancer-specific 5-year survival.ResultsA total of 6,063 patients were identified. Forty-seven percent received National Comprehensive Cancer Network guideline-adherent care, and 18.8% were treated in high-volume centers (20 or more patients/year). On multivariate analysis, lowest socioeconomic status (adjusted odds ratio [OR] 0.69, 95% CI 0.57-0.84), low-middle socioeconomic status (adjusted OR 0.76, 95% CI 0.64-0.92), and Charlson-Deyo comorbidity score 1 or higher (adjusted OR 0.78, 95% CI 0.69-0.89) were patient characteristics associated with receipt of nonguideline care. Receiving adherent care was less common in low-volume centers (45.9%) than in high-volume centers (50.9%) (effect size 0.90, 95% CI 0.84-0.96). Death from cervical cancer was more common in the nonadherent group (13.3%) than in the adherent group (8.6%) (effect size 1.55, 95% CI 1.34-1.80). Black race (adjusted hazard ratio 1.56, 95% CI 1.08-2.27), Medicaid payer status (adjusted hazard ratio 1.47, 95% CI 1.15-1.87), and Charlson-Deyo comorbidity score 1 or higher (adjusted hazard ratio 2.07, 95% CI 1.68-2.56) were all associated with increased risk of dying from cervical cancer.ConclusionAmong patients with early-stage cervical cancer, National Comprehensive Cancer Network guideline-nonadherent care was independently associated with increased cervical cancer-specific mortality along with black race and Medicaid payer status. Nonadherence was more prevalent in patients with older age, lower socioeconomic status, and receipt of care in low-volume centers. Attention should be paid to increase guideline adherence

Clinical outcomes in ovarian cancer patients receiving three versus more cycles of chemotherapy after neoadjuvant treatment and interval cytoreductive surgery

ObjectivesTo compare clinical outcomes for stage IIIC and IV ovarian cancer patients receiving neoadjuvant chemotherapy and interval cytoreductive surgery followed by up to three versus more cycles of post-operative chemotherapy.MethodsWe conducted a multi-institution retrospective cohort study of patients treated from January 2005 to February 2016 with neoadjuvant platinum-based therapy followed by interval surgery and post-operative chemotherapy. The following were exclusion criteria: more than four cycles of neoadjuvant chemotherapy, bevacizumab with neoadjuvant chemotherapy, non-platinum therapy, prior chemotherapy, and elevated CA125 values after three post-operative chemotherapy cycles. Progression-free and overall survival and toxicity profiles were compared between groups receiving up to three cycles versus more that three cycles post-operatively.ResultsA total of 100 patients met inclusion criteria: 41 received up to three cycles and 59 received more than three cycles. The groups were similar in terms of age, body mass index, performance status, tumor histology, optimal cytoreduction rates, and median number of neoadjuvant chemotherapy cycles. Median progression-free survival was 14 vs 16.6 months in those receiving up to three cycles versus more than three cycles, respectively (HR 0.99, 95% CI 0.58 to 1.68, p=0.97). Similarly, median overall survival was not different at 47.1 vs 69.4 months, respectively (HR 1.96, 95% CI 0.87 to 4.42, p=0.10). There were no differences in grade 2 or higher chemotherapy-related toxicities.ConclusionsExtending post-operative chemotherapy beyond three cycles in patients receiving neoadjuvant chemotherapy and interval cytoreductive surgery with normalization of CA125 levels was not associated with improved survival or greater toxicity. Future study in a larger cohort is warranted to define optimal length of cytotoxic treatment

Platinum resistance in gynecologic malignancies: Response, disease free and overall survival are predicted by biochemical signature: A metabolomic analysis.

OBJECTIVE: Platinum resistance, defined as the lack of response or relapse within six months of platinum-based chemotherapy, is an important determinant of survival in gynecologic cancer. We used quantitative Mass Spectrometry to identify metabolic signatures that predict platinum resistance in patients receiving chemotherapy for gynecologic cancers. METHODS: In this study 47 patients with adenocarcinoma of the ovary or uterus who were candidates for carboplatin plus paclitaxel submitted blood for quantitation of metabolites and surgical specimens for the isolation 3-dimensional organoids used to measure individual patient platinum resistance, ex vivo. Results were correlated with response, time to progression and survival. RESULTS: Of 47 patients, 27 (64.3%) achieved complete remission with a mean time to progression of 1.9 years (± 1.5), disease-free survival of 1.7 years (± 1.4) and overall survival of 2.6 years (± 1.6) and a mean cisplatin lethal concentration 50% (LC50) = 1.15 μg/ml (range 0.4-3.1). Cisplatin LC50\u27s correlated with a non-significant decrease in complete remission (RR [95% CI] =0.76 [0.46-1.27]), diminished disease-free survival (median: 1.15 vs. 2.99 years, p = 0.038) and with biochemical signatures of 186 metabolites. Receiver operating curves (ROC) of lipid ratios, branched chain amino acids and the tryptophan to kynurenine ratio identified patients at the highest risk of relapse and death (AUC = 0.933) with a sensitivity of 92.0% and specificity of 86.0% (p \u3c 0.001). CONCLUSIONS: Metabolic signatures in gynecologic cancer identify patients at the highest risk of relapse and death offering new diagnostic and prognostic tools for management of the advanced gynecologic tumors
