OBJECTIVETo investigate the prognostic factors of small cell lung cancer (SCLC) and establish a reliable model of clinical prognostic index.

METHODSKaplan-Meier and Cox regression were used to analyze the relationship between survival time and prognostic factors in 60 cases of SCLC. The prognostic factors included clinical and laboratory parameters, serum cytokeratin fragment 19 (CYFRA21-1), carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), CA125, interleukin-2 (IL-2) and soluble interleukin-2 receptors (sIL-2R).

RESULTSKaplan-Meier analysis showed that poor prognosis was in patients with KPS < 80 or extensive disease and unrelated to other clinical parameters such as age, sex and smoking index, and in patients with serum NSE > 30 micro g/L, CEA > 5.0 micro g/L, CA125 > 37 KU/L and sIL-2R > 500 KU/L. Serum IL-2 and CYFRA21-1 were also elevated, but had no significant prognostic value. Multivariate analysis indicated that serum NSE, stage and treatment of disease were independent prognostic factors. The three prognostic factors enabled establishment of a prognostic index (PI) based on a simple algorithm: PI = NSE (0 if < or = 30 micro g/L, 1 if > 30 microg/L) + stage (0 = LD, 1 = ED) + CEA (0 if < or = 5.0 microg/L, 1 if > 5.0 microg/L).

CONCLUSIONThe stage of disease, systemic treatment and the level of serum NSE are independent prognostic factors. Without considering the influence of treatment-related factors on survival, the levels of serum CEA, NSE and stage of disease before treatment are significant independent prognostic factors. PI calculated on the basis of CEA, NSE and stage is recommended to predict the survival of SCLC.

Pretransplant alpha-fetoprotein (AFP) is a useful tumor marker predicting recurrence of hepatocellular carcinoma (HCC). Little is known, however, about the relationship between changes in AFP concentration and prognosis. This study investigated the clinical significance of change in peri-transplant AFP level as a predictor of HCC recurrence. Data from 125 HCC patients with elevated pretransplant AFP level who underwent liver transplantation (LT) between February 2000 and December 2010 were retrospectively reviewed. Patients with AFP normalization within 1 month after LT were classified into the rapid normalization group (n = 97), with all other patients classified into the non-rapid normalization group (n = 28). Tumor recurrence was observed in 17 of the 97 patients (17.5%) with rapid normalization; of these, 11 patients had high AFP levels and six had normal levels at recurrence. In contrast, tumor recurrence was observed in 24 of the 28 patients (85.7%) without rapid normalization, with all 24 having high AFP levels at recurrence. Multivariate analysis showed that non-rapid normalization (harzard ratio [HR], 4.41, P < 0.001), sex (HR, 3.26, P = 0.03), tumor size (HR, 1.15, P = 0.001), and microvascular invasion (HR, 2.65, P = 0.005) were independent risk factors for recurrence. In conclusion, rapid normalization of post-LT AFP level at 1 month is a useful clinical marker for HCC recurrence. Therefore, an adjuvant strategy and/or intensive screening are needed for patients who do not show rapid normalization.

BACKGROUNDHepatic arterial infusion chemotherapy for liver metastases is under evaluation because of the high target dose and low general toxicity. To investigate the efficacy and safety of a Folfox4 regimen administered through a combined hepatic arterial and systemic infusion for the first-line treatment of colorectal cancer (CRC) with unresectable liver metastases.

METHODSTwenty-seven CRC patients with unresectable hepatic metastases and no prior chemotherapy were enrolled into the study. They received a Folfox4 regimen; 1st day: HAI of oxaliplatin 85 mg/m(2) and L-folinic acid 200 mg/m(2), followed by a bolus hepatic arterial injection of 5-fluorouracil 400 mg/m(2), then continuous HAI of 5-FU 600 mg/m(2); 2nd day: infusion of L-folinic acid 200 mg/m(2) i.v. followed by an intravenous bolus injection of 5-Fluorouracil 400 mg/m(2), then continuous infusion of 5-fluorouracil 600 mg/m(2) i.v. The patients received HAI during the odd cycles, and the intravenous administration of the same Folfox4 regimen during the even cycles.

RESULTSA total of 236 treatment cycles were given with a median of 10 cycles. The therapy generated the following results after six treatment cycles: complete response (CR) 1/27 (3.7%), partial response (PR) 17/27 (63.0%), stable disease (SD) 6/27 (22.2%), and progress disease (PD) 3/27 (11.1%). Five patients had hepatectomy. The serum levels of both carcinoembryonic antigen (CEA) and CA19-9 were significantly reduced (P < 0.05). A median time to progression of 11 months and a median overall survival of 24 months were documented. The major adverse events included grade 1/2 nausea/vomiting, upper abdominal pain, peripheral neuropathy, and neutropenia/thrombocytopenia.

CONCLUSIONSThe Folfox4 regimen administered through combined hepatic arterial and systemic infusions is efficacious and safe for the treatment of CRC with unresectable liver metastases, and it facilitates the control of local lesions.
