Meta Analysis
Vitamin and multiple-vitamin supplement intake and incidence of colorectal cancer: a meta-analysis of cohort studies.
This paper systematically evaluated the association of intake of different vitamins and multiple-vitamin supplements and the incidence of colorectal cancer. Relevant studies were identified in MEDLINE via PubMed (published up to April 2014). We extracted data from articles on vitamins A, C, D, E, B9 (folate), B2, B3, B6, and B12 and multiple-vitamin supplements. ⋯ Vitamin D was 0.87 (95 % CI 0.77-0.99); vitamin B6, 0.88 (95 % CI 0.79-0.99); vitamin B2, 0.86 (95 % CI, 0.76-0.97); vitamin A, 0.87 (95 % CI, 0.75-1.03); vitamin C, 0.92 (95 % CI, 0.80-1.06); vitamin E, 0.94 (95 % CI, 0.82-1.07); vitamin B12, 1.10 (95 % CI, 0.92-1.32); vitamin B3, 1.18 (95 % CI, 0.76-1.84). Vitamin B9 (folate), D, B6, and B2 intake was inversely associated with risk of colorectal cancer, but further study is needed. Our study featured unacceptable heterogeneity for studies of multiple-vitamin supplements, so findings were inconclusive.

This study aimed to investigate mRNA and protein expressions of SET and MYND domain-containing protein 3 (SMYD3), STAT3, and phosphorylated STAT3 (pSTAT3) in gastric cancer (GC). This study was also conducted to explore the correlations between these proteins and biological behaviors of GC. SMYD3, STAT3, and pSTAT3 expressions were detected in GC tissues and adjacent non-tumor tissues by semiquantitative/quantitative reverse transcription polymerase chain reaction and Western blot analysis. ⋯ SMYD3 expression and STAT3 or pSTAT3 expressions in GC tissues were significantly and positively correlated. Multivariate analysis results demonstrated that primary tumor location, lymph node metastasis, SMYD3 expression, and pSTAT3 expression were independent prognostic indicators of GC. pSTAT3 expression was an optimal prognostic predictor of patients, as identified by Cox regression with Akaike's information criterion value calculation. High SMYD3 and pSTAT3 expressions may indicate poor prognosis of patients with GC.

The aim of the study was to evaluate the efficacy and safety of intratumoral chemotherapy with paclitaxel liposome combined with systemic chemotherapy as induction therapy in clinical stage III unresectable non-small cell lung cancer (NSCLC). Between January 2011 and July 2014, 48 patients, stage III, performance status 0-1, with unresectable clinical stage IIIA or IIIB NSCLC suitable for definitive radiation treatment, were included in the study. Patients with T3N1M0 and T4 (ipsilateral lung nodules) N0-1M0 were not included. ⋯ A median PFS of 16.5 months (95 % CI 13.7-19.2) and median OS of 23.2 months (95 % CI 20.0-26.3) were observed. Eleven stage IIIA patients underwent surgery, for a resection rate of 58 %. Intratumoral chemotherapy with paclitaxel liposome combined with systemic chemotherapy demonstrated a considerable disease response and resection rate, with acceptable toxicity.

We have studied the efficacy of bevacizumab in colorectal cancer with unresectable metastasis patients who had undergone resection of primary tumor. The patients with unresectable metastasis during diagnosis who had undergone resection of primary tumor without chemotherapy and the patients without resection of primary tumor were included. Among patients who had met the inclusion criteria, 46 patients with resection of primary tumor and 47 without resection of primary tumor were included in the study. ⋯ Median OS was 9 months (95 % CI 1.48-16.51) in patients without bevacizumab (P = 0.012). Bevacizumab seems ineffective in mCRC patients with resected primary tumor. An increase in number of retrospective literature data and randomized, prospective studies is required about this subject.

Randomized Controlled Trial Multicenter Study
Intravenous iron alone resolves anemia in patients with functional iron deficiency and lymphoid malignancies undergoing chemotherapy.
This randomized trial evaluated ferric carboxymaltose without erythropoiesis-stimulating agents (ESA) for correction of anemia in cancer patients with functional iron deficiency. Patients on treatment for indolent lymphoid malignancies, who had anemia [hemoglobin (Hb) 8.5-10.5 g/dL] and functional iron deficiency [transferrin saturation (TSAT) ≤ 20%, ferritin >30 ng/mL (women) or >40 ng/mL (men)], were randomized to ferric carboxymaltose (1,000 mg iron) or control. Primary end point was the mean change in Hb from baseline to weeks 4, 6 and 8 without transfusions or ESA. ⋯ All ferric carboxymaltose-treated patients achieved an Hb increase >1 g/dL (control 6/9; p = 0.087), and mean TSAT was >20% from week 2 onwards. No treatment-related adverse events were reported. In conclusion, ferric carboxymaltose without ESA effectively increased Hb and iron status in this small patient population.
