The relationship between deprivation, tumour stage and the systemic inflammatory response in patients with primary operable breast cancer

Preoperative Glasgow prognostic score as a predictor of primary bladder cancer recurrence

The correlation between systemic inflammatory markers and malignancies has been assessed by a number of recent studies. The aim of this study was to prospectively assess preoperative inflammation markers and Glasgow prognostic scores (GPS) in patients who underwent surgery for primary bladder cancer (BC), and evaluate the predictive value of GPS for disease recurrence and progression. A total of 38 patients (mean age, 60.16±9.71 years; range, 33-76 years) who were treated in our department between May, 2014 and August, 2015 were enrolled in the present study. Preoperatively, patient information regarding gender, body mass index, serum C-reactive protein (CRP) and albumin levels, GPS and comorbidities, were collected and recorded. Transurethral resection of the bladder was performed, followed by histopathological evaluation of the resected material. The tumor size, stage and grade and the presence of necrosis were determined. According to the international TNM classification, the results of the histopathological analysis were as follows: Ta low- (n=24) and high-grade (n=4); and T1 low- (n=2) and high-grade (n=8). The median follow-up period was 10.1 months (range, 6-12 months). During this period, recurrence was observed in 10 cases and disease progression was detected in 1 patient. Hypoalbuminemia was encountered in 40% of the cases with recurrence, which was significantly higher compared with that in patients without recurrence (7.1%; P=0.031). In patients who had recurrence, a GPS of 1-2 points and tumor necrosis were more frequently detected compared with those without recurrence (60 vs. 7.1%, P=0.002; and 80 vs. 7.1%, P=0.001, respectively). Excluding a cystectomized case with a diagnosis of muscle-invasive BC, disease progression was not detected in any of the cases with recurrence during follow-up. Therefore, we consider that GPS and serum markers of systemic inflammatory response may be used as predictors of recurrence in patients with transitional cell BC.

Preoperative serum albumin as a prognostic factor in patients with upper urinary tract urothelial carcinoma

PURPOSE

The study evaluated whether preoperative measures of the C-reactive protein-systemic inflammatory response may predict cancer survival independent of tumor stage in patients with upper urinary tract urothelial carcinoma (UTUC).

MATERIALS AND METHODS

Between September 1999 and October 2010, 181 patients submitted to radical nephroureterectomy were available for evaluation. Multivariate survival analyses were performed using Cox's proportional hazards model and the coefficient for each factor was divided by the highest coefficient, multiplied by 4, and rounded to the nearest integer.

RESULTS

Multivariate analyses showed that tumor location, pathologic T stage, lymphovascular invasion, margin status, and albumin level were independent contributors. The bootstrap-corrected C statistics of the model were 0.813 for disease-specific survival and 0.755 for overall survival, respectively. For time to disease-specific and overall mortality for patients, integrated area under the curve values were 0.792 and 0.739, respectively. When patients were clustered into three groups according to their model-predicted survival, the 5-year disease-specific survival in the low-, intermediate- and high-risk group was 95.4%, 76.2%, and 36.9%, respectively (p<0.001), and were 87.8%, 54.4%, and 31.8%, respectively, for overall survival (p<0.001). Decision curve analysis revealed that the use of model was associated with net benefit gains relative to the treat-all strategy.

CONCLUSIONS

Pretreatment albumin is a simple biomarker based on routinely available well-standardized measures, and is not an expensive and time-consuming process. Hypoalbuminemia is an independent marker of poor prognosis in patients with upper urinary tract urothelial carcinoma.

p53 mutation, deprivation and poor prognosis in primary breast cancer

BACKGROUND

The deprivation gap for breast cancer survival remains unexplained by stage at presentation, treatment, or co-morbidities. We hypothesised that p53 mutation might contribute to the impaired outcome observed in patients from deprived communities.

METHODS

p53 mutation status was determined using the Roche Amplichip research test in 246 women with primary breast cancer attending a single cancer centre and related to deprivation, pathology, overall, and disease-free survival.

RESULTS

p53 mutation, identified in 64/246 (26%) of cancers, was most common in 10 out of 17 (58.8%) of the lowest (10th) deprivation decile. Those patients with p53 mutation in the 10th decile had a significantly worse disease-free survival of only 20% at 5 years (Kaplan-Meier logrank chi(2)=6.050, P=0.014) and worse overall survival of 24% at 5 years (Kaplan-Meier logrank chi(2)=6.791, P=0.009) than women of deciles 1-9 with p53 mutation (c.f. 56% and 72%, respectively) or patients in the 10th decile with wild-type p53 (no disease relapse or deaths).

CONCLUSION

p53 mutation in breast cancer is associated with socio-economic deprivation and may provide a molecular basis, with therapeutic implications, for the poorer outcome in women from deprived communities.
