Role of neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, lymphocyte-monocyte ratio and platelets in prognosis of patients with prostate cancer.

The aim of the present analysis was to evaluate the platelet-lymphocyte ratio (PLR), neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), platelets (PLT) and neutrophil level for their prognostic values in patients with prostate cancer who had been treated with radiotherapy. A retrospective analysis of 152 patients who were treated in the Radiotherapy Department at Maria Sklodowska-Curie National Research Institute of Oncology (Gliwice, Poland) between January 2012 and December 2014 was performed. The prognostic value (overall survival; OS) of the pre-treatment PLR, NLR, LMR, PLT, neutrophil level and other laboratory factors such as: leukocyte, lymphocyte, monocyte, hemoglobin, RBC, prostate-specific antigen level (PSA), Gleason score, age, smoking and comorbid condition were assessed using univariate analysis. The cut-off point was determined for NLR as 'elevated' at >4.66, LMR >3.26 and the PLR was considered 'elevated' at >89.6. Median follow-up was 4.9 years. The 5 and 7-year OS rates were 81.5 and 72.2%, respectively. In univariate analysis higher NLR (P=0.007), higher level of PLT (P=0.004), higher level of neutrophils (P=0.013), elevated level of leukocyte (P=0.043) and lymphocyte (P=0.043) were factors significantly associated with decreased OS. No difference was found for PLR (P=0.308) and LMR (P=0.109). The other factor associated with decreased OS were: higher Gleason score (>7; P=0.005), higher PSA level (>20 ng/dl; P=0.0001), smoking (P=0.003) and older age (>70 years; P=0.018). In multivariate analysis, NLR, LMR, leukocyte and RBC were independently associated with prognosis in patients with prostate cancer. Elevated pre-treatment NLR [hazard ratio (HR)=10.83; P=0.001), LMR (HR=3.14; P=0.007) and higher leukocyte level (HR=3.14; P=0.007) were independently associated with increased mortality risk. Overall, pre-treatment NLR, PLR, leukocyte and RBC levels were revealed to be independent prognostic factors.

Tandem autologous hematopoietic cell transplantation with sequential use of total marrow irradiation and high-dose melphalan in multiple myeloma.

The goal of this phase II trial was to evaluate safety and efficacy of a tandem autologous hematopoietic cell transplantation (auto-HCT) using sequentially total marrow irradiation (TMI) at the dose of 12 Gy (4 Gy on days -3, -2, and -1) and melphalan 200 mg/m2 for patients with multiple myeloma (MM). TMI was performed using helical tomotherapy. Additional "boosts" (total 24 Gy) were applied for patients with active lesions as revealed by PET-FDG. Fifty patients with median age 58 years (41-64 years) were included and received tandem auto-HCT. TMI resulted in absolute neutropenia in all patients. Grade 3 infections were reported in 30% patients. Other toxicities were rare. Proportion of patients who achieved at least very good partial response increased from 46% before the first auto-HCT to 82% after tandem transplantation. Complete remission rates changed from 10% to 42%, respectively. The probabilities of overall and progression-free survival at 5 years were 74% and 55%, respectively. No patient died without progression. We conclude that conditioning with TMI ± PET-guided "boosts" represents personalized treatment approach in MM and is characterized by very good toxicity profile. Tandem auto-HCT using TMI in sequence with high-dose melphalan appears safe with encouraging early efficacy.

The results of 394 consecutive cases of knee joint radiation synovectomy (radiosynoviorthesis) using 90Y.

OBJECTIVE: The aim of this study was to assess the treatment results of 90Y radiation synovectomy for chronic exudative synovitis of knee joints. METHODS: The retrospective data consist of 394 consecutive knee radiation synovectomies performed using 6 mCi (222 MBq) of 90Y. The assessment included 3-point custom pain and joint mobility scale, evaluation of joint's circumference, binary joint's temperature evaluation, patellar ballottement test, indications for puncture and its volume in applicable cases. 21 cases had to be forfeited due to missing data regarding follow-up. RESULTS: The final analysis of 373 treatment procedures performed in 253 patients yielded following results-at 6 months after treatment, 80.9% of the patients reported at least partial pain relief (including 33.3% with complete pain relief), which increased to 86.7% at one year. The pain intensity decreased over time, however, the outcomes were worse in older patients. The probability of pain recurrence was 15% at 6 months, and 28% at one year. It was highest in post-traumatic synovitis, and lowest in pigmented villonodular synovitis. The circumference of the treated knee joints decreased over the course of follow-up, however, the decrease was significantly lower in older patients. The fraction of patients with full knee joint mobility increased from 34.6 to 40.6% at 6 months and 49.2% at one year. The percentage of patients that required articular puncture decreased from 62.8% at baseline to about 35.6% at 6 months, and 32.8% at one year. Positive patellar ballottement was found in 68.5% before treatment and remained at about 40-50% during the course of follow-up. The increased temperature of the joint was reported in 51.2% at baseline and decreased to 33% at 6 months and 28.3% at one year. CONCLUSIONS: (1) Radiation synovectomy is a safe and effective method of treatment in patients with exudative synovitis, however, the pain recurrence rate is significantly higher in post-traumatic exudative synovitis compared to pigmented villonodular, undifferentiated, and rheumatoid arthritis. (2) Our results suggest that older patients have worse treatment results with radiation synovectomy compared to younger patients.

Blood serum proteins as biomarkers for prediction of survival, locoregional control and distant metastasis rate in radiotherapy and radio-chemotherapy for non-small cell lung cancer.

BACKGROUND: Several studies have documented that blood biomarkers can improve basic prognostic models in radiotherapy and radio-chemotherapy for non-small cell lung cancer. The current study evaluated the prognostic impact of six markers focusing on their utility in homogenous subsets, compared to the significance in a large heterogeneous group. METHODS: Blood samples of 337 patients who were referred for curative or palliative external beam thoracic radiotherapy for non-small cell lung cancer were collected. The concentration of osteopontin (OPN), vascular endothelial growth factor (VEGF), erythropoetin (EPO), high mobility group box 1 protein (HMGB1), insulin-like growth factor 1 (IGF-1) and platelet-derived growth factor (PDGF) in serum were measured by ELISA assay and the prognostic potential was assessed using univariable and multivariable survival models. RESULTS: Multivariable analysis revealed that out of several variables studied six dichotomized features: namely: cigarette smoking, lack of chemotherapy, palliative doses of radiotherapy, high OPN concentration, advanced T stage and high VEGF concentration had a highly significant (p < 0.005) and independent influence on overall survival in the group of 337 patients. In a subset of patients treated with curative radio-chemotherapy or radiotherapy (N = 148) tumor pathology, EPO concentration and VEGF concentration, significantly and independently influenced overall survival. In a subset of patients with squamous cell cancer (N = 206) OPN had a highly significant impact on overall survival. In contrast, in a subset of patients with nonsquamous histology (N = 131) only VEGF had a significant influence on survival. CONCLUSIONS: Blood serum proteins appear to be clinically useful prognosticators of overall survival in radio-chemotherapy and radiotherapy for non-small cell lung cancer. In unselected heterogeneous groups, dichotomized concentrations of OPN and VEGF emerged among the strongest independent prognosticators of overall survival. VEGF and EPO concentration (dichotomized) were found to be independent prognostic factors among the patients treated with curative doses of radiotherapy. The utility of OPN as a prognostic marker appeared restricted to the patients with squamous histology.

The pharmacological and hormonal therapy of hot flushes in breast cancer survivors.

The side effects of oncological treatment, which appear during or after therapy, are sometimes very annoying for patients and are not adequately treated by physicians. Among the symptoms experienced by breast cancer patients are hot flushes, which result from a natural or cancer therapy-induced menopause. The intensity of hot flushes in breast cancer patients may be more severe than those experienced by women undergoing a natural menopause. Taking into account the incidence of breast cancer and long-lasting hormone-suppression therapies, the problem of hot flushes will affect many women. Hormonal replacement therapy, the most effective therapeutic means for alleviating hot flushes, is usually contraindicated for breast cancer patients. For intense and severe hot flushes, pharmacological treatment using agents from a group of selective serotonin reuptake inhibitors and serotonin and norepinephrine reuptake inhibitors such as venlafaxine or citalopram may be introduced. Other agents from different pharmacological groups, such as clonidine, gabapentin, or pregabalin, have also proved to be effective in treating hot flushes. The efficacy of phytoestrogens has not been proven in randomized clinical trials. The importance of the placebo effect in decreasing vasomotor symptoms has also been reported in many research papers. Educating breast cancer patients in lifestyle changes which decrease the frequency and intensity of vasomotor symptoms can offer significant help too. This paper reviews the current state of research in order to assess the options for the treatment of hot flushes in breast cancer survivors.

[Radiosynovectomy of the knee--experience thereof]. / Radiosynowektomia stawu kolanowego --doswiadczenia wlasne.

The aim of the study was the evaluation of 90Y radiosynovectomy performed in chronic exudative knee synovitis. The analyzed material comprised 81 90Y injections made between 2004 and 2008. The circumference of a knee, the volume of removed exudate, the knee mobility, the presence of pain, the temperature of a knee and the presence of floating patella (exudate) were evaluated. The percentage of pain-free patients increased from 12% to 50% after 1 year; an additional 10% of patients reported pain relief. The patient percentage with an increased knee temperature fell from 42% to 31% and the patients percentage with exudates decreased from 76% to 27. No improvement was found with respect to knee circumference. The knee mobility improvement (the patients percentage with full mobility) increased from 25% to 59% one month after the treatment) and exudate volume reduction was found only in the subgroup of patients suffering from pigmented villonodular synovitis. The obtained results permit the conclusion that 90Y radiosynovectomy for chronic exudative knee synovitis is an effective treatment modality; it relieves pain and reduces the patients percentage with exudate and increased knee temperature, and in the subgroup of patients suffering from the pigmented villonodular synovitis improves the knee mobility and reduces the volume of evacuated exudate.

Half-body irradiation: a safe and acceptable treatment.

BACKGROUND: The aim of this study was an evaluation of the acute toxicity of single-fraction half-body irradiation (HBI). MATERIAL/METHODS: The material comprised 92 patients. Upper, lower, and middle HBI (UHBI, LHBI, MHBI) were performed in 34, 49, and 9 cases, respectively, with 6 Gy delivered for UHBI, 8 Gy for LHBI, and 6 or 8 Gy for MHBI. The patients' weights were measured on the HBI day. Two weeks later their weights and blood parameters were checked and diarrhea, skin toxicity (scale: 0-4), and nausea and vomiting intensity (scale: 0-3) were evaluated using WHO Toxicity Criteria. Items of all the evaluated symptoms were summarized and the means of the sums were calculated. RESULTS: Mean weight loss after HBI was 0.7 kg. One patient had grade 4 toxicity (thrombopenia). Grade 3 toxicity appeared in 9 cases (nausea and vomiting in 5, leukopenia in 1, and thrombopenia in 3). None had radiation pneumonitis. The means of the summarized items were 1.9 for UHBI than 1.4 for LHBI. The means of the summarized items were 1.6 for 8 Gy and 1.8 for 6 Gy. UHBI provoked a higher incidence and intensity of nausea and vomiting and LHBI caused a higher incidence and intensity of diarrhea. The remaining evaluated symptoms of toxicity were similar for irradiations of both halves of the body. CONCLUSIONS: From these results one can conclude that single-dose (6-8 Gy) HBI is a safe treatment, causing a low percentage of low-level, patient-acceptable adverse radiation sequels.

[Effectiveness evaluation of knee joint 90Y radiosynovectomy]. / Ocena skutecznosci radiosynowektomii stawu kolanowego przy uzyciu 90Y.

INTRODUCTION: Chronic knee synovitis with effusion, because of the special role of knee joint is an important therapeutic problem. This leads to searching for new treatment modalities. One of them is radiosynovectomy based on anti-proliferative and anti-inflammatory activity of ionizing radiation. It is made using 90Y mainly (high energy of beta [electrons] radiation [2.2 MeV], large average penetration in soft tissues [3.6 mm] and long physical half-life [2.7 days]). MATERIAL AND METHOD: Analyzed material is comprised of 30 patients (33 treatments) suffering from proliferative synovitis of knee joint treated by radiosynovectomy using intra-articular injection of 6 mCi 90Y. In 20 cases the reason of disease was non-specific reactive arthritis, in 5 rheumatoid arthritis, in 3 villonodular synovitis, in 3 psoriasis and in 2 ulcerative colitis. Symptoms duration varied from 3 to 144 months (mean 43). A knee circumference at the treatment day varied from 33.5 cm to 49 cm (mean 41). The operation was based on knee biopsy, evacuation of exudate and delivery of 6 mCi of colloid 90Y. Follow up ranged up to 14 months (mean 4.4). Patients were examined 2 weeks, 1, 3, 6 and 12 months after treatment. During examination a knee circumference was measured, a knee mobility, temperature and patella floating symptom were examined. Pain in treated region was assessed and amount of exudate was measured. RESULTS: A knee circumference and exudate amount enlarged during following controls, and compared between the treatment day and the last control did not differ significantly (41 vs. 41.6 cm and 43 vs. 42.5 ml respectively) but number of biopsies decreased. A percentage of patients with impaired knee mobility also did not change (59% vs. 58%). Probably, it was caused by resignation from control examination when symptoms disappeared. A percentage of patients without pain relief decreased from 43.5% 2 weeks after treatment to 20% one year later and a patient percentage with complete pain relief increased from 8.5% to 60%. A patient percentage with increased knee temperature and with floating patella decreased significantly (54 vs. 25% and 83 vs. 48% respectively). CONCLUSIONS: Obtained results do not allow to form univocal conclusions regarding effectiveness of 90Y radiosynovectomy. The decreasing biopsies number, decreasing percentage of patient with increased knee temperature and with floating patella; increased percentage of patients with analgetic effect and with total pain relief show a necessity of renewed evaluation of this treatment modality on the base of bigger patients number and longer and more precise observation.

[Evaluation of the effectiveness of the calcaneal spurs radiotherapy]. / Ocena skutecznosci radioterapii bolesnych ostróg kosci pietowych.

The radiotherapy results of 46 calcaneal spurs were analysed. Patients were irradiated using fraction dose of 1.0 Gy, 1.5 Gy or 2.0 Gy up to total dose of 2.0-22.5 Gy. All patients previously had chronic pain in the plantar region influencing possibility of walking and not reacting for conventional treatment. Whole group was periodically controlled after the treatment completion. The mean follow-up period was 12.5 months. The complete pain relief was observed in 9% cases one month after treatment and in 52% during the last control. The lack of analgetic effect was noted only in 3% cases as well one month after the treatment as during the last examination. Performed statistical analysis showed only inverse significant correlation between degree of pain relief six months after the treatment and duration of symptoms. Obtained results allow to form conclusion that radiotherapy of calcaneal spurs is easy, effective and safe way of analgetic treatment giving good results after low fraction and total delivered doses and that its efficacy depends on symptoms duration what is correlated to disease stage.
