Determinants and prognostic implications of malignant ascites in metastatic papillary renal cancer.

ABSTRACT: OBJECTIVE:To describe the incidence of ascites in metastatic papillary renal cell cancer (pRCC), identify the factors associated with its development and evaluate its prognostic effect on the survival of these patients. METHODS:A retrospective evaluation of the medical records of patients with metastatic pRCC seen at National Cancer Institute (2000-2014) was undertaken. Logistic regression to identify predictors of the development of malignant ascites and Kaplan-Meier analysis to estimate survival was done. RESULTS:Overall, 106 consecutive patients with metastatic pRCC were identified; sufficient data were available in 100 patients to enable assessment of ascites. Further, 20% had evidence of malignant ascites. Median age at diagnosis of ascites was 48.0 years (26.1-76.6 years) and median time to development of ascites from initial diagnosis of metastatic disease was 16.0 (0-73.3) months. There was no significant difference in the incidence of ascites between patients with hereditary and sporadic pRCC (P = 0.803) or among patients with different subtypes of pRCC (P = 0.456). Elevated platelet-lymphocyte ratio predicted development of malignant ascites in our cohort (P = 0.009). Median overall survival was shorter for patients who developed ascites [25.0 (10.2-39.8) months] compared with patients who did not develop this complication [42.5 (30.5-54.4) months, P = 0.041]. CONCLUSION:To our knowledge, this is the first systematic evaluation of the incidence, predictors, and prognostic effect of ascites in metastatic pRCC. Malignant ascites is a common manifestation of metastatic pRCC and is associated with a shorter overall survival. An elevated platelet-lymphocyte ratio predicts a higher risk of developing malignant ascites.

Project description:BackgroundAscites is the accumulation of fluid within the abdominal cavity. Most women with advanced ovarian cancer and some women with advanced endometrial cancer need repeated drainage for ascites. Guidelines to advise those involved in the drainage of ascites are usually produced locally and are generally not evidence-based. Managing drains that improve the efficacy and quality of the procedure is key in making recommendations that could improve the quality of life (QoL) for women at this critical period of their lives.ObjectivesTo evaluate the effectiveness and adverse events of different interventions for the management of malignant ascites drainage in the palliative care of women with gynaecological cancer.Search methodsWe searched CENTRAL, MEDLINE, and Embase to 4 November 2019. We checked clinical trial registries, grey literature, reports of conferences, citation lists of included studies, and key textbooks for potentially relevant studies.Selection criteriaWe included randomised controlled trials (RCTs) of women with malignant ascites with gynaecological cancer. If studies also included women with non-gynaecological cancer, we planned to extract data specifically for women with gynaecological cancers or request the data from trial authors. If this was not possible, we planned to include the study only if at least 50% of participants were diagnosed with gynaecological cancer.Data collection and analysisTwo review authors independently selected studies, extracted data, evaluated the quality of the included studies, compared results, and assessed the certainty of the evidence using Cochrane methodology.Main resultsIn the original 2010 review, we identified no relevant studies. This updated review included one RCT involving 245 participants that compared abdominal paracentesis and intraperitoneal infusion of catumaxomab versus abdominal paracentesis alone. The study was at high risk of bias in almost all domains. The data were not suitable for analysis. The median time to the first deterioration of QoL ranged from 19 to 26 days in participants receiving paracentesis alone compared to 47 to 49 days among participants receiving paracentesis with catumaxomab infusion (very low-certainty evidence). Adverse events were only reported among participants receiving catumaxomab infusion. The most common severe adverse events were abdominal pain and lymphopenia (157 participants; very low-certainty evidence). There were no data on the improvement of symptoms, satisfaction of participants and caregivers, and cost-effectiveness.Authors' conclusionsCurrently, there is insufficient evidence to recommend the most appropriate management of drainage for malignant ascites among women with gynaecological cancer, as there was only very low-certainty evidence from one small RCT at overall high risk of bias.

Project description:The purpose of the study was to identify a comprehensive prognostic system of pretreatment clinical parameters in 425 patients (pts) with metastatic renal-cell carcinoma treated with different subcutaneous (s.c.) recombinant cytokine-based home therapies in consecutive trials. Treatment consisted of (A) s.c. interferon-alpha 2a (INF-alpha), s.c. interleukin-2 (IL-2) (n=102 pts), (B) s.c. IFN-alpha 2a, s.c. IL-2, and i.v. 5-fluorouracil (5-FU) (n=235 pts) or (C) s.c. IFN-alpha 2a, s.c. IL-2, and i.v. 5-FU combined with p.o. 13-cis-retinoic acid (13cRA) (n=88 pts). Kaplan-Meier survival analysis, log-rank statistics, and Cox regression analysis were employed to identify risk factors and to create a multiple risk factor model. The following pretreatment risk factors were identified by univariate analysis: (1) three and more metastatic sites, (2) presence of liver, lymph node or bone metastases, (3) neutrophil count > or = 6500 cells microl(-1), (4) serum lactate dehydrogenase level (LDH) > or = 220 U l(-1), and (5) serum C-reactive protein level (CRP) > or = 11 mg l(-1). Cox regression analysis with forward stepwise variable selection identified neutrophil count as the major prognostic factor (hazard ratio=1.9, P<0.001), while serum levels of LDH and CRP, time between diagnosis of tumour and onset of metastatic disease, number of metastatic sites, and bone metastases were significant but somewhat less important prognostic variables within the multiple risk factor model (hazard ratio < or = 1.5). Patients were assigned to one of the three risk groups according to cumulative risk defined as the sum of simplified risk s.c.ores for six pretreatment variables. Low-, intermediate-, and high-risk patients achieved a median overall survival of 32+ months (95% CI 24, 43; 5-year survival of 27%), 18+ months (95% CI 15, 20; 5-year survival of 11%), and 8+ months (95% CI 6, 10; 5-year survival of 5%), respectively. These prognostic categories are helpful both in individual patient care and in the assessment of patients entering prospective clinical trials.
