Background For selected early stage small cell lung cancer (SCLC), curative intent surgery is often performed. Previous studies, predominantly from East Asia, reported that high neutrophil to lymphocyte ratio (NLR), and platelet–lymphocyte ratio (PLR) correlate with poor prognosis in several types of tumors including SCLC. Our aim was to investigate the prognostic value of NLR and PLR in Caucasian patients with resected SCLC, as potential tool to select patients for multimodal treatment including surgery. Methods Consecutive patients evaluated at three centers between 2000 and 2013 with histologically confirmed and surgically resected SCLC were retrospectively analyzed. NLR and PLR at diagnosis was used to categorize patients into “high” and “low” groups based on receiver operating curve analysis. Univariate and multivariate analyses were used to evaluate the impact of clinical and pathological characteristics on outcome. Results There were a total of 189 patients with a median age of 58 years, and the majority had stage I or II disease. We found a significant correlation between NLR and tumor stage (p = 0.007) and age (p = 0.038). Low NLR (LNLR) was associated with significantly longer overall survival, while PLR had no prognostic impact. There were significant associations between NLR and PLR but not with gender, vascular involvement, tumor necrosis, peritumoral inflammation, or tumor grade. Conclusion Pre-operative LNLR may be a favorable prognostic factor in stage I–II SCLCs. PLR is not prognostic in this population. LNLR is easy to assess and can be integrated into routine clinical practice. Further prospective studies are needed to confirm these observations.

Oral mucositis (OM) is a common and potentially dangerous complication of anticancer treatment. Since there are only few therapeutic options for OM, there is a need to identify novel approaches to its management and prevention. The aim of the present study was to evaluate the efficacy of Oncoxin (ONCX), a nutritional supplement that contains microelements, vitamins, amino acids and certain biologically active substances of natural origin, in cancer patients who receive chemotherapy, radiotherapy or a combination of the two. A total of 15 male and female patients (aged 45–75 years) with malignant neoplasms, who had been prescribed radiotherapy, chemotherapy or a combination of the two, with an Eastern Cooperative Oncology Group performance status score ≤3, and grade 2–3 OM based on the World Health Organization (WHO) Oral Toxicity Scale, were enrolled in a 20-day study; 10 patients were in the ONCX group and 5 served as controls. The patients were allowed to use any anticancer treatment and any type of OM care. In addition to their current treatment, patients in the ONCX group used 25 ml of the ONCX nutritional supplement twice daily for 20 days. The mean WHO Oral Toxicity Scale grade decreased by 41% in the ONCX group after ~7 days from the beginning of the study compared with minimal change in the control group. At the end of the study, the difference was even more prominent, with a 73 and 20% decrease from baseline in the ONCX and control groups, respectively (P<0.001). During the entire trial period, patients in the ONCX group were able to eat normally during 65% of the time, in contrast to only 29% in the control group (P=0.04). There were no statistically significant changes in absolute body mass, or in the number of days with normal appetite. This was a pilot study aiming to show the benefits of the ONCX nutritional supplement in OM, and the results demonstrated that ONCX rapidly improved the symptoms of OM and helped to maintain normal eating habits in patients undergoing cancer treatment.

Treatment of cancer often requires the use of adjuvant chemotherapy (ACT). In real clinical practice, numerous patients suffer from severe toxicity and reduced quality of life (QoL). Hence, there is a need to maintain QoL and to reduce therapy toxicity to comply with recommended chemotherapy (CT) regimens. The present study focused on the effects of the multi-component nutritional supplement Oncoxin (ONCX) on QoL and CT-induced toxicity in patients undergoing ACT. A total of 133 patients aged 50–70 years with gastric cancer IIB-IIIC or non-small cell lung cancer IIB-IIIA were enrolled in the present study: 84 received ONCX, and 49 were included in the control arm and received CT only. It was identified that after 2 weeks of treatment the patients receiving ONCX exhibited clinically meaningful improvement of QoL (measured by Edmonton Symptom Assessment System Questionnaire) compared with those in the control group (odds ratio, 2.07; 95% CI, 1.00–4.29). By the end of a 3 week-period, the albumin level was higher in patients of the ONCX group compared with those in the control group (mean, 38.1; 95% CI, 37.1–39.1 g/l; vs. mean, 35.5; 95% CI, 33.9–37.0; P=0.03; respectively). Furthermore, the use of ONCX substantively reduced the hepatic toxicity of ACT. The present prospective real clinical setting study revealed positive effects of ONCX on QoL and ACT toxicity. The present study was retrospectively registered under the study registration number NCT03550482 at (June 8, 2018).

Введение. Лечение злокачественных новообразований часто требует применения адъювантной химиотерапии (АХТ). В реальной клинической практике доля пациентов, имеющих серьёзные проявления токсичности противоопухолевого лечения, достаточно высока. Таким образом, необходимость снижения токсичности терапии и сохранение интенсивности дозы химиопрепаратов являются актуальной задачей онкологии. Данная статья посвящена результатам исследования влияния многокомпонентного нутрицевтика Онкоксин на переносимость АХТ. Материалы и методы. В исследование было включено 133 больных раком желудка IIВ-IIIС или немелкоклеточным раком лёгких IIВ-IIIА в возрасте 50-70 лет; 84 получали Онкоксин, 49 составили контрольную группу.
