RESUMO

PURPOSE: Serial longitudinal enumeration of circulating tumor cells (CTCs) has shown its prognostic value on progression-free survival and overall survival (OS) in patients with stage IV breast cancer. This study prospectively evaluated the role of CTCs as a prognostic marker during further progression of metastatic breast cancer (MBC). METHODS: Among 476 MBC patients recruited between 2010 and 2015, the 103 patients with a known CTC status at baseline (CTCBL) and within 4 weeks of tumor progression (CTCPD) were included. Progressive disease (PD) was defined according to the Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1). Using the CellSearch method, < 5 and ≥ 5 CTCs per 7.5 ml blood were determined as negative and positive, respectively. A shift in CTC status from baseline to progression ([Formula: see text] to [Formula: see text] and vice versa) was considered as alternating KineticsBL-PD. RESULTS: Median follow-up was 29.9 [21.2, 40.0] months. CTCPD positivity (37%, n = 38) was associated with a significantly shorter OS than CTCPD negativity (8.0 [5.1, 10.9] vs 22.6 [15.3, 39.8] months; P < 0.001). Alternating KineticsBL-PD was observed in 24% of the patients. This significantly changed the OS prediction of [Formula: see text] patients ([Formula: see text] vs [Formula: see text], 11.4 [9.7, not available (NA)] vs. 7.6 [4.4, 11.5] months; P = 0.044) and [Formula: see text] patients ([Formula: see text] vs. [Formula: see text], 8.4 [4.0, NA] vs. 22.6 [18.9, NA] months, respectively; P < 0.001). Prediction of survival was significantly improved (P = 0.002) by adding CTCPD status to clinicopathological characteristics and CTCBL status. CONCLUSIONS: CTC status upon further disease progression is a prognostic factor that could significantly improve well-established models. Thus, it represents a potential additional instrument supporting treatment decision.

RESUMO

Hepatitis B core antibody (HBcAb) seropositivity has been associated with a higher rate of hepatitis B virus (HBV) reactivation after chemotherapy, even in patients who are hepatitis B surface antigen (HBsAg) negative. However, little is known about the risk of HBV reactivation after autologous hematopoietic stem cell transplantation (auto-HCT). We evaluated the incidence of HBV reactivation, liver toxicity, and survival in patients with multiple myeloma (MM) who received auto-HCT at our institution. We retrospectively identified 107 MM patients with resolved HBV infection (HBcAb positive, HBsAg negative) and 125 patients with negative HBV serology (control subjects) who were matched for age, timing of auto-HCT from diagnosis, cytogenetics, disease status at transplant, induction therapy, and preparative regimen. All patients underwent auto-HCT between 1991 and 2013. Primary endpoints were HBV reactivation, defined as HBsAg positivity or ≥10-fold increase in HBV DNA, and hepatotoxicity, as defined in the U.S. National Cancer Institute Common Terminology Criteria for Adverse Events v3.0. In the resolved HBV infection group, 52 patients (49%) were HBsAb positive and 24 (22%) had detectable HBV DNA before auto-HCT. Only 1 patient with resolved HBV infection received pre-emptive antiviral therapy with lamivudine, whereas 4 patients received lamivudine (n = 3) or tenofovir (n = 1) at reactivation after auto-HCT for a median duration of 12 months. HBV reactivation occurred in 7 of 107 patients (6.5%) in the resolved HBV group. Median time to HBV reactivation from auto-HCT was 16 months. The cumulative incidence of grade 2 or greater hepatotoxicity was 30% in the resolved HBV infection group and 22% in the control group (hazard ratio, 1.3; 95% confidence interval, .7 to 2.3; P = .4). Nonrelapse mortality for the 2 groups was not statistically different at 2 years (P = .06), although it trended higher in the control group than in the resolved HBV infection group (8% versus 1%). The median progression-free survival (PFS) and overall survival (OS) durations in the resolved HBV infection and control groups were 21 versus 18 months (P = .5) and 53 versus 67 months (P = .2), respectively. Our data suggest that resolved HBV infection in patients undergoing auto-HCT for MM is associated with a low risk of HBV reactivation and hepatotoxicity; these complications were reversible and did not adversely affect the PFS or OS.

RESUMO

Pancreatic acinar cell carcinoma is an uncommon neoplasm of the exocrine pancreas associated with a poor prognosis, especially when found to be metastatic. Since there are a lack of large studies and prospective, randomized data, no consensus treatment guidelines are available. Here, we report a case of a patient with recurrent metastatic acinar cell carcinoma involving the liver who had presented initially with pancreatic panniculitis. She received chemotherapy with capecitabine and oxaliplatin prior to resection of her primary tumor and liver metastases, after which she experienced a 30 months recurrence-free survival. Upon relapse, she was treated with a combination of capecitabine and oxaliplatin followed by maintenance capecitabine. Now, more than seven years after initial diagnosis, the patient remains stable without evidence of active disease. This case highlights the possibility of therapeutic success even for a patient initially deemed unresectable due to a poor performance status who responded to fluoropyrimidine-based therapy.

RESUMO

Triple-negative breast cancer (TNBC) is a group of very aggressive breast tumours, characterised by lack of expression of oestrogen receptor (ER), progesterone receptor (PR) and erb-b2 receptor tyrosine kinase 2 (ERBB2/HER2). Nevertheless, TNBCs show different clinical characteristics and are very diverse regarding prognostic outcome. So far, only a few prognostic markers for TNBC have been reported that could be helpful for therapeutic stratification. Here we have analysed the expression of S100P and HYAL2 using immunohistochemistry (IHC) in a TNBC cohort of 98 patients with a follow-up for recurrence and death. TNBC patients with high expression of both proteins showed significantly shorter progression-free survival (PFS) (mean PFS=35.9months, P=0.001) compared to TNBC patients with high expression levels of only one of the proteins (mean PFS=69.4months) and to TNBC patients with low expression of both proteins (mean PFS=83.3months). Moreover, multivariate Cox-regression model showed the combined expression of S100P and HYAL2 as independent prognostic factor for PFS (P=0.001). The expression of S100P and HYAL2 indicated similar prognostic effect to the overall survival (OS) of TNBC patients. In addition, high expression levels of both S100P and HYAL2 showed significant association with different clinicopathological characteristics, such as more recurrence events (P=0.004), and higher occurrence of metastasis (P=0.002). Our study proposes S100P and HYAL2 as potential prognostic markers for TNBC.
