RESUMEN
BACKGROUND: Thymic carcinoma (TC) is a rare subtype of thymic epithelial malignancy. Surgical resection is a mainstay in the treatment of TC, while radiotherapy and chemotherapy are modalities used in adjuvant or palliative setting. Immune checkpoint inhibitors (ICI) including anti-PD-1 (programmed cell death 1) antibodies represent an emerging treatment modality in TC; however, their administration could be associated with life-threatening toxicity. CASE: We present a case of a 59-year-old female with grade III TC, who had received neoadjuvant chemotherapy followed by surgery and subsequent adjuvant radio-immunotherapy with an ICI, nivolumab. We provide our experience with the toxicity of an administered treatment. RESULTS: Fourteen days after the first dose of nivolumab and on 21st day after starting of radiotherapy (total dose of 40 Gy), the patient developed fulminant myocarditis with subsequent heart failure. Despite immunosuppressive therapy with high-dose glucocorticoids and mycophenolate mofetil and intensive support, the patient died within 6 days after the onset of first symptoms. CONCLUSION: Physicians should be aware of these extremely rare, but potentially fatal complications of immunotherapy.

BACKGROUND: Monoclonal immunoglobulins (paraproteins) are produced by B lymphocytes in lymphoproliferative disorders. A single monoclonal immunoglobulin is homogeneous in terms of its structure, and it can occur in human serum at high concentration and cause significant interference in laboratory assays. CASE: We present a case of an 84-year-old man who was admitted to the hospital for progression of dyspnea. Basic laboratory tests showed a serum concentration of conjugated bilirubin, measured using the diazo spectrophotometric method, which was much higher than that of total bilirubin. The cause of the discrepancy was attributed to analytical interference by monoclonal immunoglobulins, which helped establish a diagnosis of lymphoproliferative disorder. CONCLUSION: Monoclonal immunoglobulins are relatively rare in serum but are an important cause of analytical interference. Monoclonal immunoglobulins should always be considered a source of interference when unexpectedly high, low, or contradictory data are encountered, and appropriate confirmatory tests (electrophoresis, imunofixation) should be performed in such circumstances. Failure to do so can result in errors in diagnosis and inadequate treatment. Conversely, when samples contain abnormal and especially high monoclonal immunoglobulin levels, the biochemical data should be carefully examined for any discrepancies, such as paraprotein interference, and the results should be taken into consideration in patient management.Key words: paraproteins - lymphoproliferative disorders - bilirubin - interferenceThe authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study.The Editorial Board declares that the manuscript met the ICMJE recommendation for biomedical papers.Submitted: 22. 1. 2016Accepted: 1. 12. 2016.

BACKGROUND: The aim of the study is to compare measured glomerular filtration rate by technetium radiolabled diethylene tiamine pentaacetic acid (mGFR DTPA) to estimated GFR (eGFR). Glomerular filtration rate (GFR) is estimated from serum creatinine (eGFRcreatinine), serum cystatin C (eGFRcystatin C) and by combined equation (eGFRcreatinine+cystatin C). This study focuses on oncology patients considered for treatment with cisdiamminedichloroplatinum (cisplatin). We evaluated the impact of different GFR methods on the reduction of cisplatin dose. PATIENTS AND METHODS: The study population consisted of 112 consecutive oncology patients from oncology center treated in the town of Zlin in the Czech Republic, who were considered for cisplatin treatment. mGFR DTPA was performed by dynamic renal 99mTc scintigraphy method using diethyltriaminepentaacetic acid. Creatinine and cystatin C were determined by newly standardized tests. Estimation of GFR was calculated using The Chronic Kidney Disease Epidemiology (CKDâEPI) equations which were established in 2009 and 2012. RESULTS: The median (interquartile range) of mGFR DTPA was 1.335 ml/s/1.73 m2 (1.070-1.725). The median of eGFRcystatin C 1.195 ml/s/1.73 m2 (0.885-1.625) was lower than mGFR DTPA (p<0.05). The median of eGFRcreatinine 1.460 ml/s/1.73 m2 (1.210-1.660) was higher than mGFR DTPA (p<0.05). Correlation analysis and BlandâAltman plots show high individual differences between mGFR DTPA and all eGFRs. CONCLUSIONS: Oncology patients are a very special group of patients who dif-fer from general population. There are significant individual differences between mGFR DTPA and all eGFRs, impacting detection rate of CKD and potential drug dosage adjustment.

BACKGROUND: Cyproterone acetate is associated with hepatotoxicity during prostate cancer treatment. The information about its toxic mechanism and risk factors is limited, based on pharmacovigilance reports and published case reports only. CASE: We describe a case of a patient treated with cyproterone acetate (200 mg/day for 9 months) for adenocarcinoma of the prostate. The 75-year-old patient was admitted for the development of jaundice and loss of appetite to the T. Bata Regional Hospital in Zlin, Czech Republic. Laboratory values ALT 994 U/l, AST 1,046 U/l, ALP 193 U/l, GGT 1,128 U/l, bilirubin 177 µmol/l, conjugated bilirubin 138 µmol/l, albumin 26 g/l, Quick time INR 1.23. The concomitant medication included atorvastatin 10 mg daily. Clinical and laboratory outcomes showed acute fulminant liver failure caused pre-dominantly by hepatocellular damage. Hepatotoxicity induced by cyproteron acetate was diagnosed after exclusion of other causes, with a gradual improvement after discontinuation of the respective drug treatment. CONCLUSION: All patients treated with cyproteron acetate for prostate cancer are in risk for the development of liver failure and therefore should be monitored and well educated. More information is needed to sufficiently identify risk factors and explain mechanism of damage.

The aim of the study was to define prognostic factors of overall and event- free survival in patients with germ cell tumors progressing after platinum-based induction chemotherapy with or without surgery. A total of 98 progressing patients were identified out of 700 patients with germ cell tumors treated with platinum-based induction chemotherapy in National Cancer Institute in Bratislava with or without surgery. 98 progressing patients received first salvage chemotherapy from October 1986 to November 2007 due to progression after a previous partial or complete response to induction chemotherapy as well as patients who failed to achieve favourable response to primary therapy. Prognostic factors of survival and event-free survival after first salvage chemotherapy were assessed by univariate analysis. For all 98 progressing patients the median time from the start of induction chemotherapy to progression was 10,2 months (range: 0-256,7 months). 24 (24 %) patients relapsed after 2 years. Median overall survival time following progression was 25,4 months. Estimated 2- and 5- year overall survival rate for all progressing patients was 46 % (95 % CI 41-61%) and 24 % (95% CI 31-51%) respectively. Survival after first salvage chemotherapy was significantly enhanced for patients with age more than 40 years at primary diagnosis, nonvisceral metastasis at the time of induction chemotherapy, prior CR to induction chemotherapy, progression-free interval > 2 years, serum human chorionic gonadotropin level at relapse above or bellow 100 IU/l, a normal serum lactate dehydrogenase level at relapse, one site of metastasis at relapse, treatment with cisplatin-based first salvage chemotherapy, first regimen VIP and favourable response to salvage chemotherapy. Estimated 2- and 5-year event-free survival rate for all patients was 30% (95% CI 24-43% ) and 16%(95% CI 19-37% ) respectively. As a significant favourable prognostic factors of event-free survival were identified: prior CR to induction chemotherapy, progression-free interval > 2 years, one site of metastasis at relapse, treatment with cisplatin-based first salvage chemotherapy, first line salvage regimen VIP and favourable response to salvage chemotherapy. Identification of prognostic features in patients with germ cell tumors progressing after platinum-based induction chemotherapy may direct salvage therapy and requires further investigation of new combination of salvage therapy for those with poor prognosis. Our study showed the indispensable revaluating of chemosenzitivity in patients with late relapses and therapeutic value of additive surgical approach after salvage chemotherapy in patients with reccurent germ cell tumors.

BACKGROUNDS: Cancer metastasis to skeletal muscle is very rare. Lung cancer, renal cell carcinoma and malignant melanoma have been reported as the most frequent primary tumours. Diagnosis of muscle metastasis from other primary cancer sites is more than problematic. CASE: In this paper we report a case of metastasis of colorectal cancer in a 44-year-old man who underwent left-sided hemicolectomy due to the tumour mass in his left colic flexure followed by liver metastasectomy and cryocautery of the non-resectable metastasis in the VII segment. Subsequently, the patient was treated with two lines of chemotherapy. However, shortly after initiation of the second chemotherapy line he started to suffer from unbearable pain in the lumbosacral region. Neither a whole spinal cord MRI nor abdominal CT scan and scintigraphy explained the origin of the pain. Finally, PET/CT examination clarified the origin of the pain and showed massive hypermetabolic metastatic lesions in the muscles, further confirmed by autopsy. CONCLUSION: Thus, among the different imaging techniques, FDG PET/CT enables the detection of metabolically highly active tumour cells, undetectable by other conventional imaging means.

In a randomised phase 3 trial, panitumumab significantly improved progression-free survival (PFS) in patients with refractory metastatic colorectal cancer (mCRC). This analysis characterises the association of PFS with CRC symptoms, health-related quality of life (HRQoL), and overall survival (OS). CRC symptoms (NCCN/FACT CRC symptom index, FCSI) and HRQoL (EQ-5D) were assessed for 207 panitumumab patients and 184 best supportive care (BSC) patients who had at least one post-baseline patient-reported outcome (PRO) assessment. Patients alive at week 8 were included in the PRO and OS analyses and categorised by their week 8 progression status as follows: no progressive disease (no PD; best response of at least stable disease) vs progressive disease (PD). Standard imputation methods were used to assign missing values. Significantly more patients were progression free at weeks 8-24 with panitumumab vs BSC. After excluding responders, a significant difference in PFS remained favouring panitumumab (HR=0.63, 95% CI=0.52-0.77; P<0.0001). At week 8, lack of disease progression was associated with significantly and clinically meaningful lower CRC symptomatology for both treatment groups and higher HRQoL for panitumumab patients only. Overall survival favoured no PD patients vs PD patients alive at week 8. Lack of disease progression was associated with better symptom control, HRQoL, and OS.

First line treatment of patients pts with poor-prognosis GCT, using BEP, is unsatisfactory. T-BEP (paclitaxel followed by BEP) demonstrated promising efficacy in the group of pts with intermediate and poor prognosis GCT. We present the results achieved with 1st line T-BEP in pts with poor-prognosis CGT. Twenty-four pts received T-BEP as initial therapy. Three pts (12.5%) had primary mediastinal GCT. Four cycles of T-BEP were given 21 days apart. Paclitaxel 175 mg/m2 was administered on day 1 before administration of BEP. The administration of G-CSF was not scheduled. Surgical resection of all radiographic residua was considered. All pts were assessable for response. Complete or partial response with negative tumor markers was achieved in 13 pts (54.2%; CI 95%: 34.3-74.1%). Median follow-up is 35.6 months. Median survival was not achieved and median time-to-progression is 9.5 months. Myelosuppression was the major toxicity with Gr3-4 granulocytopenia experienced in 52.1% of all courses. There were two treatment-related deaths due to sepsis. Patients treated with 1st line T-BEP didn't achieve higher response rate or time to progression. However, the overall survival observed in our study is surprisingly long. We do not recommend using this regimen without G-CSF support due to substantial toxicity.

The aim of this study was to determine efficacy and toxicity of TIP combination (paclitaxel, ifosfamid, cisplatin) as first salvage treatment in patients with relapsed germ cell tumours (GCTs). Excellent results were achieved from TIP combination with a dose 250 mg/m(2) of paclitaxel [5]. Our hypothesis was that comparable efficacy with less toxicity could be achieved even with a lower dose of 175 mg/m(2) paclitaxel in TIP. In 17 consecutive patients with failed standard 1st line treatment, we used four to six courses of paclitaxel 175 mg/m(2) on day 1 and ifosfamide 1,200 mg/m(2) plus cisplatin 20 mg/m(2), both on day 1 through 5, every 3 weeks. Eleven patients achieved favorable response (65%; 95% confidence interval, 42 to 87%) with 7 complete responses (41%). Estimated 2-year disease free survival is 47% (95% CI, 23-71%). Treatment combination was well tolerated and myelosupression was major toxicity. Granulocytopenia Gr3-4 was observed in 8% and febrile neutropenia in 7% of the courses. No case of severe neurotoxicity or treatment-related death was observed. In our study, TIP combination had good toxicity profile. The results however, did not show expected treatment efficacy and we raise the idea of paclitaxel dosage relevance in TIP.

The aim of the study was to determine the efficacy and toxicity of gemcitabine, cisplatin and paclitaxel (GCP) combination as a first salvage treatment of patients with relapsed GCT. Four courses of paclitaxel 175 mg/m(2) and cisplatin 50 mg/m(2), both on day 1, and gemcitabine 1000 mg/m(2), on days 1 and 8, every 3 weeks, were given to 12 consecutive patients who had failed standard 1st line treatment. Six patients (50%; 95% CI 21-79%) achieved favourable response and two of them are maintained 38+ and 29+ months. Median survival time was 16 months (range, 0.77-38+). All, but two patients had hematological toxicity Gr3-4 with infectious complication seen only in 6 courses of therapy. GCP is an active second-line combination regimen for relapsed GCTs with acceptable toxicity profile. However the results of this study did not show expected treatment efficacy and we raise the idea of cisplatin dosage relevance in this combination.

BACKGROUND: Oxaliplatin and raltitrexed both are active anticancer agents in the treatment of patients with advanced colorectal carcinoma: They have different mechanisms of action and toxicity profiles and have shown at least additive effects in experimental and preliminary clinical studies. The aim of this disease oriented Phase I-II study was to determine the maximum tolerated dose (MTD), the dose-limiting toxicities (DLT), and the objective response rate of this combination in patients with advanced colorectal carcinoma. METHODS: Between April 1998 and March 1999, 69 patients with measurable metastatic colorectal carcinoma who previously were unexposed to palliative chemotherapy were enrolled. In the Phase I part of the study, 27 patients were treated with 3-weekly courses of a fixed dose of raltitrexed (3 mg/m(2) given as a 15-minute intravenous infusion) followed by a 2-hour infusion of oxaliplatin, which was escalated in consecutive cohorts of three to six patients from 85 mg/m(2) to 100 mg/m(2), 120 mg/m(2), 130 mg/m(2), and 140 mg/m(2). After having defined the toxic dose, 42 additional patients were entered at one dose level below to define the therapeutic index of this combination more precisely. RESULTS: In the Phase I part of the study, during the first three dose levels, only one patient each experienced DLT (Grade 3 increase in transaminases, diarrhea, and stomatitis); at level 4, two of the first six patients entered had Grade 3 neutropenic infection or peripheral neurotoxicity, whereas dose level 5 (oxaliplatin 140 mg/m(2)) constituted the toxic dose with three of three patients experiencing DLT (Grade 3 asthenia, transient amaurosis, and diarrhea with Grade 4 neutropenia). Externally reviewed objective responses were noted in 9 of these 27 patients (33%), and stable disease occurred in 12 patients (44.4%). Among the 42 patients who were treated subsequently at the MTD level (Phase II portion), 20 patients (47.6%) responded (95% confidence interval, 32-62.6%), and 21 patients (50%) had stable disease. Their median progression free survival was 9.0 months, and the median overall survival, with 42 patients (67%) currently alive, is > 14.5 months. Treatment tolerance at the MTD was acceptable, with only 9 of 42 patients (21%) experiencing Grade 3-4 neutropenia; Grade 3 nonhematologic adverse reactions included increase in serum transaminases in 6 patients, peripheral neuropathy in 3 patients, diarrhea in 3 patients, and both stomatitis and emesis in only 1 patient each. CONCLUSIONS: The described objective response and toxicity data, which are in agreement with preliminary results of other Phase I-II studies, support the promising therapeutic potential of this combination in the treatment of patients with advanced colorectal carcinoma. Due to its substantial antitumor activity, tolerance (at the recommended MTD level), and convenient 3-weekly outpatient administration schedule, further evaluation of this regimen seems warranted.

Intermediate high dose VIP (etoposide, ifosfamide, cisplatin) achieved comparable efficacy and improved tolerance in comparison with high-dose chemotherapy plus PBSC in poor risk germ cell tumors. The aim of this study was to confirm the effectivity and tolerance of this regimen in clinical practice. Twenty-five consecutive patients, 9 previously untreated with poor prognosis and 16 relapsed, were treated with 1.6 VIP or 1.9 VIP+PBSC. A relative dose intensity of 1.6 VIP was used in 14 patients and 11 patients received the intensity of 1.9 VIP. Clinical response was achieved in 56% of patients. Fifty-eight percent of patients have survived more than 1 year and 44% more than 2 years. No significant difference was noted between previously treated and untreated patients, as well as between the patients on 1.6 VIP and 1.9 VIP, with the exception of improved 1-year survival of patients on 1.9 VIP. One of four cisplatin-refractory patients achieved durable partial remission with a normal level of tumor markers. Serious non-hematological toxicity was rare. Myelotoxicity of 1.9 VIP was less serious in comparison with 1.6 VIP regimen, but the difference was not significant. Sequential intermediate high-dose therapy is an effective and tolerable regimen for patients with poor risk germ cell tumor as well as for relapsed patients.

Cisplatin-based chemotherapy is highly effective in advanced seminoma, but at the cost of a considerable toxicity. The response rate of carboplatin is comparable with cisplatin combinations but the relapse rate is higher. Our study assesses the efficacy and the toxicity of the combination of carboplatin and cyclophosphamide in patients with advanced seminoma. Nineteen consecutive patients received 6 cycles of intravenous cyclophosphamide 750 mg/m2 and carboplatin 350 mg/m2, repeated every 21 days. The overall objective response rate was 100%, 11 patients (58%) achieved a complete response and 8 patients (42%) showed a partial response. At median follow up of 4.2 years 3 patients (15%) relapsed. The 2-year disease-free survival and the overall survival are 72 and 94%, respectively. This outpatient treatment was well tolerated and the toxicity was mild. One patient had granulocytopenic fever and one patient had grade 3 cystitis. The combination therapy with carboplatin and cyclophosphamide is an effective and tolerable regimen in advanced seminoma.

Between March 1990 and May 1993 seventy three patients with previously untreated breast cancer, Stage III or IV without osseal metastases were randomized to sodium clodronate 1600 mg daily p.o.(arm A = 37 patients) or placebo (arm B = 36 patients) over 2 years, additionally to standard therapy. Ten patients were not evaluable for response because of short duration of therapy (less than 2 months). Bone metastases developed in 30% of patients in arm A and 23% patients in arm B. Median time to appearance of bone metastases was 13 months in arm A and 28 months in arm B. Non-bone metastases appeared in 48% patients in arm A and in 48% patients in arm B. Time to development of non-bone metastases was 20 months in arm A and 16 months in arm B. Five-year survival was 41% in arm A and 39% in arm B. There were no significant differences between the treated and control arms.

The paper presents an analysis of fungemia cases which were caused by C. parapsilosis in a cancer center within 10 years, with the aim to compare risk factors and the outcome with fungemias caused by C. albicans and other non-albicans Candida spp. fungemias. Before 1990 (1988-1989) in our institutes C. parapsilosis fungemias were not observed at all. During 1990-1997, the proportion of C. parapsilosis among fungemias increased, in 1990-1993 from 0% to 7.1% in 1996-1997 to 14.2-15%. It represents 25% out of non-albicans Candida spp. fungemias and 7.9% out of all fungemias and is the third commonest pathogen after C. albicans (50.5%) and C. krusei (9.9%). Two from eight (25%) C. parapsilosis fungemias were breakthroughs, one appeared during prophylaxis with ketoconazol and one with fluconazol. Considering the proportion of C. parapsilosis among blood cultures, 13 of 170 blood cultures contained C. parapsilosis (6.6% among all yeasts from blood cultures). C. parapsilosis was the second commonest fungal organism isolated from blood cultures (after C. albicans) in our cancer center. Infected vascular catheters were surprisingly not the major risk factor: central venous catheters were documented as a source in two cases only. The commonest risk factors were similar to those occurring with other fungemias--such as preceding antimicrobial therapy (62.5%), neutropenia (50%) and prior prophylaxis with azoles.

One hundred and twenty-three breakthrough bacteraemias (BB) were defined during a 5-year period in a National Cancer Centre, among 9986 admissions and a total of 979 bacteraemic episodes analysed. Of 123 bacteraemias in 103 patients, 77 were polymicrobial and 116 of the 323 organisms isolated were resistant to currently administered antimicrobial agents. Sixty-seven of the bacteraemic episodes were catheter-associated, as confirmed by the isolation of the same organisms from both blood and catheter tip. The strains isolated most frequently were coagulase-negative staphylococci (30.5%), corynebacteria (10%), Pseudomonas aeruginosa (10%), Enterococcus faecalis (9%) and viridans streptococci (8.5%). Gram-positive aerobes accounted for two-thirds of all micro-organisms isolated during breakthrough bacteraemic and fungaemic episodes. Polymicrobial episodes were associated more frequently with vascular catheters and neutropenia, and had a less favourable outcome than monomicrobial infections. Relapse was associated more frequently with catheter-related episodes, but the overall mortality rate was similar and independent of catheter insertion. Breakthrough bacteraemic and fungaemic episodes were associated more frequently with acute leukaemia. Catheter removal, as an independent variable, and modification of antimicrobial therapy were essential for better outcome.

One hundred twenty three breakthrough bacteraemias (BB) during 5 years in a National Cancer Institute, among 9986 admissions and 979 bacteraemic episodes were analysed. 123 BB were caused by 323 microbes, only 116 were resistant (31.5%) to currently administered antimicrobials. Sixty seven of 123 bacteraemic episodes were catheter associated confirmed by isolation of the same organisms from the blood and catheter tip. 77/123 BE were polymicrobial. The most frequently isolated strains were coagulase negative staphylococci (30.5%), Corynebacteria (10%), Ps. aeruginosa (10%), Str. faecalis (9%) and Viridans streptococci (8.5%). Gram-positive aerobes accounted for two-thirds of all organisms isolated during breakthrough bacteraemic and fungaemic episodes. Mixed polymicrobial breakthrough bacteraemic and fungaemic episodes were more frequently associated with vascular catheter insertion and neutropenia, and had a less favourable outcome in comparison to monomicrobial infections. The relapse was associated more frequently with catheter related bacteraemic and fungaemic episodes, but the overall mortality rate was similar independently from catheter insertion. Breakthrough bacteraemic and fungaemic episodes were associated more frequently with acute leukaemia. Polymicrobial breakthrough bacteraemic and fungaemic episodes were associated more frequently in neutropenic episodes and in venous catheters. Regarding the outcome, an extraction of the catheter with no dependence on variable and modification of antimicrobial therapy were essential for the improvement in the prognosis. (Tab. 5, Ref. 20.).

In a comparative randomized trial, teicoplanin 5 mg/kg plus either netilmicin 5 mg/kg or pefloxacine 10 mg/kg was administered in a once daily empiric therapy to 40 cancer patients with fever and neutropenia after cytotoxic chemotherapy. Both regimens were analyzed with respect to the localisation of the underlying disease, catheter presence and agents isolated from blood culture. The cure and improvement rate were 80% (teicoplanin plus netilmicin) and 85% (teicoplanin plus pefloxacin), with no statistically significant difference between the groups. Teicoplanin with either an aminoglycoside or a quinolone administered once daily seems to be a suitable approach in empiric therapy for fever in neutropenia and may prevent catheter insertion in cancer patients.
