The capsule-associated gene of Cryptococcus neoformans, CAP64, is actually linked to pH homeostasis.
This study clarified the predictive impact of serum biomarkers on therapeutic sensitivity to nivolumab in patients with gastric cancer (GC).

The outcomes of 27 patients who received nivolumab to treat postoperative recurrent or unresectable advanced GC were reviewed. Blood testing was performed immediately before and after two courses of nivolumab. We also focused on the rate of change of each blood variable.

The decrease in albumin (Alb) levels (p=0.035) and increase in lactate dehydrogenase (LDH) levels (p=0.012) after two courses of nivolumab were significantly larger in patients with disease progression. Furthermore, therapeutic resistance was significantly associated with an elevated LDH-to-Alb ratio (LAR) after two courses of nivolumab.

Decreased Alb or increased LDH levels after two courses of nivolumab predicted nivolumab sensitivity in patients with GC. An increased LAR was a meaningful predictor of nivolumab resistance.

Side effects of zolendronic acid (ZA) and RANKL inhibitors (RANKL-I) include impaired wound healing and osteonecrosis of the jaw. Platelet rich fibrin (PRF) enhances wound healing and bone remodelling in vivo and in vitro. However, the topical use PRF in the surgical treatment of patients with medicament-related osteonecrosis of the jaw is relatively new and not thoroughly investigated. Furthermore, the potential attenuation of the PRF effect following antiresorptive treatment remains unclear. Therefore, we investigated the concentration of growth factors within the PRF in healthy volunteers and in patients with antiresorptive treatment.

Blood samples from healthy volunteers and patients were used to produce PRF. The levels of EGF, VEGF, PDGF-BB, TGF-β1, BMP-2, and CD31 in the PRF was investigated by ELISA.

ZA treatment induced a significant decrease in EGF and TGF-β1 levels, whereas RANKL-I caused lower TGF-β1 levels.

Reduced EGF levels in PRF after ZA treatment may explain the delayed wound healing and question the positive effect of PRF in these patients. PRF use in patients undergoing RANKL-I treatment seems to be more justified.

Primary tumor location and RAS and BRAF V600E mutations are predictors of the efficacy of epidermal growth factor receptor (EGFR) inhibitors. However, there are limited reports on their effects on the outcomes of third-line chemotherapy with EGFR inhibitors in metastatic colorectal cancer (mCRC) patients.

We retrospectively collected the clinical data of KRAS exon 2 wild type (WT) mCRC patients treated with EGFR inhibitor monotherapy or EGFR inhibitor plus irinotecan as third-line chemotherapy. The association between primary tumor location, RAS (KRAS exon 3, 4 or NRAS), BRAF V600E, and PIK3CA mutational status, and treatment outcome was evaluated.

A total of 72 patients were included in this study. In multivariate analysis, RAS (p=0.004) and BRAF mutations (p=0.00008) were independent factors for shorter PFS. Poor performance status (p=0.01) and BRAF mutation (p=0.00002) were independent factors for shorter OS, whereas primary tumor location and PIK3CA mutation did not influence survival.

Additional analysis of RAS and BRAF mutations could contribute to the selection of patients who are likely to benefit from third-line EGFR inhibitors, regardless of primary tumor location.

This phase II trial evaluated the efficacy and safety of neoadjuvant nab-paclitaxel plus cyclophosphamide (CPA) plus trastuzumab (AbraC-HER) in patients with early HER2-positive breast cancer.

This was a single-arm, open-label, single-center prospective phase II study. The primary endpoint was pathological complete response rate (pCR rate). The secondary endpoints were clinical antitumor efficacy and the frequency and severity of adverse events.

Fifty-nine patients were enrolled in this study. pCR (ypT0/is ypN0) was achieved in 29 patients (49%). The overall response rate was 88.1% (52/59) in all patients. Dose reductions because of adverse events occurred in 3 patients (5.1%) and relative dose intensity was 98%. Compared to Abra-HER, AbraC-HER induced fewer adverse effects.

Treatment with nab-paclitaxel plus CPA plus trastuzumab was tolerable and effective with a high pCR rate. This AbraC-HER neoadjuvant therapy may be a feasible new treatment option for patients with early HER2-positive breast cancer.

Matrix metalloproteinases (MMPs) degrade extracellular matrix and process regulatory proteins. this website Recently, a membrane-bound 82kDa variant of proMMP-9 identified on myeloid blasts was shown to be associated with prognosis.

To investigate the role of 82kDa proMMP-9 with acute lymphoblastic leukemia (ALL) and chronic lymphoid leukemia (CLL), we performed flow-cytometry analysis of expression on ALL blasts (n=18) and CLL lymphocytes (n=21) from blood and correlated data with clinical parameters.

In ALL, mature B-linear blasts expressed higher levels of 82kDa proMMP-9 compared to T-linear blasts. Elevated levels of 82kDa proMMP-9 were found in elderly patients and at patients with relapse. No correlation was observed on blood cells and extramedullary disease. In CLL, the 82kDa proMMP-9 expression did not correlate with any of the clinical parameters.

Our findings suggest that higher levels of 82kDa proMMP-9 expression on blast cells may correlate with a more unfavorable ALL-subtype. Further studies are required to clarify the prognostic role of the 82kDa pro-MMP-9 expression.
