Adjuvant chemotherapy is a crucial part of treatment for patients with locally advanced colon cancer. This study was conducted to investigate the actual practice in the use of adjuvant chemotherapy for patients with high-risk stage II or stage III colon cancer in South Korea. ⋯ In South Korea, FOLFOX was the most commonly used regimen for adjuvant chemotherapy and its efficacy was the main cause for selecting this regimen. Patients receiving 5-FU/LV, capecitabine, or UFT/LV had older age, worse PS and lower disease stage (stage II) than patients receiving FOLFOX or CAPOX.

We attempted to systematically determine the association between dietary intake of vitamin C and risk of prostate cancer. PubMed and Embase were searched to obtain eligible studies published before February 2015. Cohort or case-control studies that reported the relative risk (RR)/odds ratio (OR) estimates with 95% confidence intervals (CIs) for the association between vitamin C intake and prostate cancer risk were included. ⋯ Stratifying the overall study according to study design yielded pooled RRs of 0.92 (95%CI: 0.86-0.99, p = 0.027) among cohort studies and 0.80 (95%CI: 0.71-0.89, p = 0.000) among case-control studies, with no heterogeneity in either subgroup. In the dose-response analysis, an inverse linear relationship between dietary vitamin C intake and prostate cancer risk was established, with a 150 mg/day dietary vitamin C intake conferred RRs of 0.91 (95%CI: 0.84-0.98, p = 0.018) in the overall studies, 0.95 (95%CI: 0.90-0.99, p = 0.039) in cohort studies, and 0.79 (95%CI: 0.69-0.91, p = 0.001) in case-control studies. In conclusion, intake of vitamin C from food was inversely associated with prostate cancer risk in this meta-analysis.

We have scrutinized a previously analyzed cohort of classical Hodgkin lymphoma patients for evidence of a CD20 over-expression. This was pursued in order to determine whether all the 24 (12.6%) CD20+++ patients had clinical and/or biological profiles which would warrant a separate consideration and treatment or would carry a different outcome from our 166 CD20 (-) classical Hodgkin lymphoma patients. ⋯ We suggest that the generally accepted view to the contrary be revised. In addition, we propose alternative interpretations for the low expression of CD20 found in a majority of Hodgkin-Reed-Sternberg cells in classical Hodgkin lymphoma.

Information on outcome of breast cancer patients treated in the community is scarce. Data on outcome of patients treated in real-life clinical practice may provide useful information for performance improvement. ⋯ Patients treated outside clinical trials in a multidisciplinary fashion according to guidelines have comparable, and at times better, survival compared to data from trials or population statistics. Locally generated outcome data could be valuable for evaluating results of treatment at individual practices for the purpose of quality assessment and improvement. Our data also provides report of increased rate of breast conserving surgery from Middle East.

Little information is available on the long-term outcomes of patients with localised prostate cancer. ⋯ Patients with stage I+II localised prostate gland carcinoma have improved survival compared with the normal male population. This finding cannot be explained solely by the administration of prostate carcinoma treatments, suggesting that men who participate in PSA screening may have better overall health behaviors and care than men who do not participate in screening. Future research should examine how treatment choice, especially an "active surveillance" approach to care, affects survival in these patients more than ten years after diagnosis.
