Background: In the last decade, a series of analyses failed to identify predictive biomarkers of resistance/susceptibility for anti-angiogenic drugs in metastatic colorectal cancer (mCRC). We conducted an exploratory preplanned analysis of serum pro-angiogenic factors (SErum aNgiogenesis-cenTRAL) in 72 mCRC patients enrolled in the phase II CENTRAL (ColorEctalavastiNTRiAlLdh) trial, with the aim to identify potential predictive factors for sensitivity/resistance to first line folinic acid-fluorouracil-irinotecan regimen (FOLFIRI) plus bevacizumab.

Methods: First-line FOLFIRI/bevacizumab patients were prospectively assessed for the following circulating pro-angiogenic factors, evaluated with ELISA (enzyme-linked immunosorbent assay)-based technique at baseline and at every cycle: Vascular endothelial growth factor A (VEGF-A), hepatocyte growth factor (HGF), stromal derived factor-1 (SDF-1), placental derived growth factor (PlGF), fibroblast growth factor-2 (FGF-2), monocyte chemotactic protein-3 (MCP-3), interleukin-8 (IL-8).

Polymorphisms contribute to inter-individual differences and show a promising predictive role for chemotherapy-related toxicity in colon cancer (CC). TOSCA is a multicentre, randomized, non-inferiority, phase III study conducted in high-risk stage II/stage III CC patients treated with 6 vs 3 months of FOLFOX-4 or XELOX adjuvant chemotherapy. During this post-hoc analysis, 218 women and 294 men were genotyped for 17 polymorphisms: TYMS (rs34743033, rs2853542, rs11280056), MTHFR (rs1801133, rs1801131), ERCC1 (rs11615), XRCC1 (rs25487), XRCC3 (rs861539), XPD (rs1799793, rs13181), GSTP1 (rs1695), GSTT1/GSTM1 (deletion +/-), ABCC1 (rs2074087), and ABCC2 (rs3740066, rs1885301, rs4148386).

Background: Dihydropyrimidine dehydrogenase (DPD) catabolises ∼85% of the administered dose of fluoropyrimidines. Functional DPYD gene variants cause reduced/abrogated DPD activity. DPYD variants analysis may help for defining individual patients' risk of fluoropyrimidine-related severe toxicity.

Article Synopsis
  • Previous research indicated that high levels of lactic dehydrogenase (LDH) in colorectal cancer patients may enhance the effectiveness of bevacizumab treatment.
  • A phase II trial with 81 patients aimed to examine the effects of combining bevacizumab with FOLFIRI on response rates, overall survival, and progression-free survival based on LDH levels.
  • The trial results showed no significant difference in response rates or progression-free survival between patients with high and low LDH levels, although those with low LDH had better overall survival, leading to the conclusion that LDH levels should not be considered a predictive factor for treatment effectiveness in this context.

Background: Colorectal cancer is the third most common and the third most lethal cancer in both men and women in developed countries. About 75% of cases are first diagnosed when the disease is classified as localized or regional, undergo potentially curative treatment and enter a post-treatment surveillance program. Although such programs drain significant resources from health systems, empirical evidence of their efficacy is scanty.

We investigated 17 polymorphisms in 11 genes (TS, MTHFR, ERCC1, XRCC1, XRCC3, XPD, GSTT1, GSTP1, GSTM1, ABCC1, ABCC2) for their association with the toxicity of fluoropyrimidines and oxaliplatin in colorectal cancer patients enrolled in a prospective randomized trial of adjuvant chemotherapy. The TOSCA Italian adjuvant trial was conducted in high-risk stage II-III colorectal cancer patients treated with 6 or 3 months of either FOLFOX-4 or XELOX adjuvant chemotherapy. In the concomitant ancillary pharmacogenetic study, the primary endpoint was the association of polymorphisms with grade 3-4 CTCAE toxicity events (grade 2-4 for neurotoxicity).

Haematological toxicity characterized by delayed and reversible neutropenia and/or thrombocytopenia is an adverse effect observed in 40% of patients receiving fotemustine. We report the case of a 66-year-old man with metastatic malignant melanoma treated with fotemustine as monotherapy. A severe persistent and prolonged thrombocytopenia occurred, so that chemotherapy was discontinued.

The aim of the study was to evaluate the activity of cisplatin (CDDP) plus vinorelbine (VNR) in patients with advanced non-small cell lung cancer (NSCLC) progressing after paclitaxel plus gemcitabine. Treatment consisted of CDDP 80 mg/m(2) administered on day 1 and VNR 25 mg/m(2) administered on day 1 and 8, repeated every 3 weeks. Nine patients who relapsed after partial response and eight patients refractory to prior CT received a minimum of two treatment cycles: three patients achieved a PR (18%; 95% CI: 4-43%), four had stable disease and 10 had disease progression.

Background And Methods: Infections are the main cause of death in most haematologic malignancies. We studied 95 autopsies of patients who died from haematologic neoplasms in the period 1980-1989 at Niguarda Cà Granda Hospital.

Results And Conclusions: Infections were the cause of death in 63% of patients.
