SYNCHRONOUS DIAGNOSIS OF TESTICULAR AND THYROID CANCER IN A YOUNG MALE.

Testicular cancer is the most common neoplasm in young males. The early diagnosis and the appropriate treatment make it a curable malignancy in over 90% of the patients, but 6% of the patients with testicular cancer develop a second, mostly treatment-related, malignancy in another primary site many years after the first diagnosis. The simultaneous appearance of a testicular tumor with another primary neoplasm is rarely described in the literature. Here is presented an interesting case of a coexisting non-seminomatous germ cell testicular tumor with a papillary thyroid carcinoma, which was detected early during post-treatment restaging of the testicular tumor. The synchronous presence of these two neoplasms might indicate a probable common pathogenetic background. As treatment-related oncogenesis is highly improbable in this case and the common environmental factors are not known yet, the interest is focused on genetic predisposition. Recent discoveries in molecular genetics show that the two neoplasms share common genetic alterations in the RAS and BRAF genes, which affect the significant signaling pathways. Interestingly, BRAF-V600E was positive in both primary malignancies in our individual.

Vaccine third dose and cancer patients: necessity or luxury?

The current state of the SARS-CoV-2 pandemic is an equilibrium between expanding vaccine coverage on the one hand, and emergence of variants of concern which compromise vaccine effectiveness and enhance viral transmission on the other. Inequity in vaccine distribution, primarily an ethical issue, challenges this equilibrium, as industrialized countries prepare to administer a third booster dose to their population. Solid tumor cancer patients typically respond well to initial full vaccination and someone could argue that they should not be prioritized for an adjuvant third dose, since protection from severe disease has largely been achieved with the two-dose regimen. Nevertheless, their immune status is dynamic and not all of them exhibit an adequate immune response. A booster third dose is necessary for the inadequate responders, while it will result in better protection of all patients from mild disease as well, which if presented could have ominous consequences due to their overall frailty, and their need to adhere to strict therapeutic schemes. International scientific and public health communities should develop approaches that allow for wide immediate vaccination coverage of the developing world, in parallel with administration of adjuvant doses to solid tumor cancer patients (and other at-risk categories) of the developed nations, in order to avoid prolonging the pandemic, which will be prospectively against cancer patients' best interest.

A Holistic Approach to Assessment of Population Exposure to Radiation: Challenges and Initiatives of a Regulatory Authority.

A regulatory authority for radiation safety should continuously evaluate and improve the national safety framework, in line with current requirements and standards. In this context, the Greek Atomic Energy Commission initiated a series of concerted actions. The radiation dose to the population due to public and medical exposures was assessed. The assessment of dose due to public exposure was based on measurements of radon concentrations in dwellings, radionuclide concentrations in environmental samples, and air dose rates; the assessment of dose due to medical exposure was based on dose measurements for typical examinations or procedures and data on their frequency. The mean effective dose to a member of the population was found to be 4.5 mSv (1.8 mSv and 2.7 mSv from medical and public exposures, respectively). Regarding occupational exposure, aircrew dose assessment, eye lens monitoring, and the national dose registry were significantly improved. With respect to artificial tanning (sun beds), the ultraviolet radiation produced was assessed and the practices followed were observed. Results demonstrated exceedance of the 0.3 W m erythema effective irradiance limit set in European Union standards by 63.5% of the sun beds measured, along with general noncompliance with standards. An overarching activity was the upgrade of the Greek Atomic Energy Commission information system in order to collect and disseminate radiation data electronically, launch a networking strategy for interaction with stakeholders, and facilitate the process of regulatory control. In response to the above findings, regulatory actions have been initiated.

Metastatic soft tissue sarcoma: current treatment landscape and future perspectives.

INTRODUCTION: The therapeutic armamentarium for advanced soft tissue sarcoma (STS) has increased over the last few years. Doxorubicin monotherapy or in combination is now the established first line treatment. Beyond first line treatment, no standard therapy has been established. Novel drugs have reached the late-clinical stage development demonstrating to be effective in controlled studies. While these novel treatments can be beneficial to a subset of patients, even producing long lasting remissions, a significant fraction of the STS population derives limited benefit. This is due to the fact that STS is a very heterogeneous disease with different histopathologic features, biological characteristics and clinical behaviour. Areas covered: The primary aim of this review is to summarize data from recent phase III clinical trials in unselected STS population, and to discuss their impact on the current clinical practice. Phase I-II trials of special interest are discussed as well. Expert commentary: Although our efforts in this research task are ongoing, the integration of biological therapies, the anti-angiogenesis targeted treatments as well as immunotherapy that may further improve the long term control of advanced STS are of special clinical interest. Clinical management of advanced STS should be tailored to each patient in order to optimize therapy.

Microwave endometrial ablation after endometrial curettage for the management of heavy menstrual bleeding.

OBJECTIVES: The aim of the present study was to evaluate the eticacy of microwave endometrial ablation after endometrial curettage, in selected patients with heavy menstrual bleeding. MATERIAL AND METHODS: Thirty-two premenopausal women with heavy menstrual bleeding underwent microwave endometrial ablation at the Department of Obstetrics and Gynecology of the University of Patras Medical School. All patients did not respond to previous medical treatment, had completed their childbearing, and did not desire future fertility. The authors chose endometrial curettage rather than hormonal pretreatment (GnRH analogs, danazol) for endometrial preparation. Posttreatment follow up protocol included physical and ultrasonographic evaluation at three, six, nine, and 12 months for the first year and yearly after. RESULTS: The authors had no cases of uterine perforation, thermal injury to adjacent organs, and infection or sepsis. During follow up, there was a gradual decrease in amenorrhea rate (90.6% - 68.8%) and in satisfaction rate (90.6% - 71.9%). Moreover during follow up, eight women underwent to total abdominal hysterectomy. Among them, seven women had uterine myomas and one woman had adenomyosis. CONCLUSIONS: Endometrial preparation with endometrial curettage seems to be a good alternative to hormonal pretreatment. It has the advantage of avoiding delays, side effects, and cost of hormonal pretreatment. Moreover, microwave endometrial ablation after endometrial curettage is successful and highly acceptable.

Transvaginal ultrasound-guided aspiration of benign ovarian cysts.

In our study, we evaluate the diagnostic and therapeutic efficacy of transvaginal ultrasound-guided aspiration of benign ovarian cysts in selected patients. A total of 46 women with benign ovarian cysts were referred to our outpatient clinic. The aspirated fluid was collected and sent for cytological analysis. All women were re-evaluated at 1, 3 and 6 months after the procedure. The cytological analysis was negative for malignancy in all cases. Our study showed an overall recurrence rate for ovarian cysts of 39.1%. Women with endometriotic ovarian cysts have an increased incidence of recurrence, 62.5% (n = 5), in comparison with serous cysts, 35.2% (n = 12) and serous-haemorrhagic cysts, 15% (n = 1), χ(2) = 9.913, df = 2, p = 0.007. The results of our study reveal that transvaginal ultrasound-guided aspiration of benign ovarian cysts is a simple, safe and effective procedure.

Storage stability studies for tributyltin determination in human urine samples using headspace solid-phase microextraction and gas chromatography mass spectrometry.

A headspace solid-phase micro-extraction (HS-SPME) method was employed in order to study the effect of storage conditions of human urine samples spiked with tributyltin (TBT) using gas chromatography and mass spectrometry. To render the analyte more volatile, the derivatization (ethylation) was made in situ by sodium tetraethylborate (NaBEt(4) ), which was added directly to dilute unpreserved urine samples and in buffers of similar acidity. The stability of TBT in human urine matrix was compared with the stability of TBT in buffer solutions of similar pH value. Critical parameters of storage conditions such as temperature and time, which affect the stability of TBT in this kind of matrix, were examined extensively. The tests showed that the stability of TBT remains practically satisfactory for a maximum of 2 days of storage either at +4 or 20°C. Greater variations were observed in the concentration of TBT in human urine samples at +4°C and lower ones at -20°C over a month's storage. The freeze-thaw cycles have negative effect on the stability and should be kept to a minimum. The results from spiked urine samples are also discussed in comparison to those acquired from buffer solutions of equal TBT concentration.

Association of soluble apoptotic markers with impaired left ventricular deformation in patients with rheumatoid arthritis. Effects of inhibition of interleukin-1 activity by anakinra.

Myocardial function is impaired in rheumatoid arthritis (RA). Inhibition of interleukin (IL)-1 activity reduces experimental myocardial infarction by limiting apoptosis. We investigated whether a) soluble apoptotic markers are related with impaired left ventricular (LV) performance and b) treatment with anakinra, an IL-1 receptor antagonist, reduces apoptotic markers leading to improved LV performance in RA. We studied 46 RA patients. In an acute, double-blind cross-over trial, 23 patients were randomised to a single injection of anakinra or placebo and after 48 hours (h) to the alternative treatment. In a chronic trial, 23 patients who received anakinra for 30 days were compared with 23 patients who received prednisolone. At baseline, 3 h and 30 days after treatment, we measured circulating IL-1ß, tumour necrosis factor (TNF)-α, Fas, Fas-ligand and caspase-9 to assess apoptosis. At baseline and 30 days after treatment, we assessed LV longitudinal strain, strain rate and E/Em ratio using 2D-speckle tracking and tissue Doppler echocardiography. At baseline, increased apoptotic markers were related with reduced LongSRS and increased E/Em (p<0.05). After 3 h and 30 days of anakinra, there was a reduction in Fas (median 481 vs. 364 vs. 301 pg/ml), Fas-ligand (median 289 vs. 221 vs. 190 pg/ml), caspase-9 (median 1.90 vs. 1.40 vs. 1.07 ng/ml), TNF-α and IL-1ß (p<0.05 for all comparisons). E/Em, LongS and LongSRS were improved after anakinra (p<0.01) and their percent changes were related with the corresponding changes of Fas and caspase-9 (p<0.05). No changes of the examined parameters were observed after prednisolone. In conclusion, inhibition of IL-1 activity by anakinra reduces apoptotic markers leading to improved LV performance in RA.

A comparison of pain and anxiety associated with the administration of maxillary local analgesia with Wand and conventional technique.

AIM: This was to compare the sensation of pain when injections were given using the Wand computer controlled local analgesia (LA) system and a conventional technique in children of pre-school and school age. METHODS: 38 children were randomly assigned to either a treatment or control group. The treatment (Wand) group consisted of 20 children, while the control group (conventional LA technique) consisted of 18 children. The children were aged between 39.0 and 120.0 months with a mean age of 81.9 months (SD- 23.2). One operator carried out all local analgesia administrations. Pain sensation was rated using the VAS scale by the operator, each child and their parent. Anxiety was rated using the Venham scale. RESULTS: No statistical difference in pain sensation and anxiety was found when the Wand was used, compared with the conventional technique (P=0.710, P=0.976). The results also showed no significant difference in anxiety change between males and females in the two groups (P=0.714). CONCLUSION: There was no difference in the pain or anxiety experienced by the children in the conventional and Wand group.

Lowering interleukin-1 activity with anakinra improves myocardial deformation in rheumatoid arthritis.

OBJECTIVE: Inhibition of interleukin-1 activity improves nitro-oxidative stress, endothelial and coronary function. The authors investigated (a) the association of nitro-oxidative stress and endothelial function with myocardial deformation, (b) the effects of anakinra, an interleukin-1a receptor antagonist on myocardial deformation in patients with rheumatoid arthritis (RA). METHODS: The authors compared 46 RA patients to 23 normal controls. 23 patients received anakinra (150 mg subcutaneously once daily) and 23 patients a 5-mg increase of prednisolone dose for 30 days. At baseline and post-treatment this study assessed (a) the left ventricular (LV) longitudinal, circumferential and radial strain and strain rate, using speckle tracking echocardiography, (b) the coronary flow reserve (CFR), (c) the flow-mediated endothelial-dependent dilation of the brachial artery (FMD) and (d) nitrotyrosine (NT) and malondialdehyde blood levels. RESULTS: Patients had impaired baseline myocardial deformation indices compared to controls (p<0.05). CFR and NT levels were related to longitudinal strain, systolic and diastolic strain rate, circumferential strain and systolic strain rate (p<0.05). FMD was related to longitudinal and circumferential diastolic strain rate (p<0.01). Compared to baseline, anakinra-treated patients increased the longitudinal strain (-17.8% (3.7%) vs -22.1% (3.5%)), systolic (-1.02 (0.23) l/s vs -1.25 (0.23) l/s) and diastolic (0.96 (0.37) l/s vs 1.20 (0.39) l/s) longitudinal strain rate, circumferential strain and strain rate (p<0.05 for all comparisons). No significant changes were observed among prednisolone-treated patients CONCLUSIONS: Myocardial deformation is impaired in RA patients and is related to nitro-oxidative stress and endothelial dysfunction. Chronic inhibition of IL-1 improves LV deformation in parallel with endothelial function and nitro-oxidative stress.

Analysis of 7 immunohistochemical markers in male germ cell tumors demonstrates the prognostic significance of p53 and MIB-1.

BACKGROUND: Various prognostic factors have been investigated in order to predict the minority of male germ cell tumor (GCT) patients who will develop resistant disease. However, no prognostic system has been proven accurate. MATERIALS AND METHODS: Paraffin-embedded tissue specimens, obtained from primary lesions during the initial diagnosis of 83 advanced chemotherapy-treated GCT male patients, were stained for 7 immunohistochemical markers: p53, bax, bcl-2, MIB-1, topoisomerase IIa, c-kit and COX-2. The percentage of positive cells for each marker was measured for each patient. Cox regression was used for the prognostic factor analysis. RESULTS: All patients were followed for a median of 4 years. Nineteen patients had seminoma and 64 non-seminomatous GCT. In univariate analysis, only p53 (hazard ratio (HR) = 4.01, 95% confidence interval (CI) = 1.25-12.84, p = 0.019) and MIB-1 (HR = 3.16, 95% CI = 1.06-9.45, p = 0.039) were found to be prognostic for disease-specific survival. The best prognostic cut-off values of p53 and MIB-1 were 10% and 30% respectively. In multivariate analysis, these two markers obtained independent significance only when considered in combination (HR = 6.63, 95% CI = 1.40-31.41, p = 0.017, for patients with one or both markers above their cut-off), while the International Germ Cell Consensus Cancer Group (IGCCCG) risk was the most significant (HR = 7.99, 95% CI = 1.96-32.52, p = 0.004, for the high-risk group). However, the expression of these markers seemed to be significantly correlated with known prognostic factors. Nevertheless, we identified 34 patients of low IGCCCG risk expressing both markers below their cut-off with excellent survival. CONCLUSION: Among 7 immunohistochemical markers, p53 and MIB-1 demonstrated prognostic significance. Their combination may contribute to improvement of the accuracy of the currently approved prognostic system (IGCCCG).

Complete response after imatinib mesylate administration in a patient with chemoresistant stage IV seminoma.

The case of a young man with stage IV chemoresistant pure seminoma overexpressing KIT, who achieved complete remission (CR) after the administration of imatinib mesylate (400 mg once daily), along with a third-line chemotherapy regimen, consisting of paclitaxel (150 mg/m2), oxaliplatin (100 mg/m2) and gemcitabine (800 mg/m2) every 2 weeks with granulocyte colony-stimulating factor (G-CSF) support is reported. The patient had received first- and second-line regimens consisting of ifosfamide, bleomycin, etoposide cisplatin (5 cycles, every 3 weeks) and methotrexate, vinblastine, actinomycin D, cyclophosphamide, cisplatin (3 cycles, every 3 weeks) respectively, without having normalized beta-human chorionic gonadotrophin (beta-HCG) levels. Following treatment with imatinib plus third-line chemotherapy (paclitaxel, oxaliplatin, gemcitabine), the levels of beta-HCG were reduced to within the normal limits during the first month of treatment. Therefore, the patient underwent surgical resection of the residual disease from the retroperitoneum and liver, which proved to be only necrotic tissue. The patient is under close follow-up, with no evidence of disease, 36 months after the completion of chemotherapy and 32 months post surgery.

Cellular immune responses in hepatitis B virus e antigen negative chronic hepatitis B.

The immunopathogenesis of hepatitis B e antigen (HBeAg) negative chronic hepatitis B (CHB) virus (HBV) infection has not been adequately investigated. We studied the cellular immune responses of peripheral lymphocytes using proliferating assays, intracellular cytokine staining (ICS) and ELISPOT interferon-gamma (IFN-gamma) assays after non-specific and specific stimulation with whole HBV proteins and synthetic peptides. Thirty patients with HBeAg negative CHB, eleven HBsAg inactive carriers, nine patients with acute hepatitis B and 22 healthy controls were included in the study. Patients with HBeAg negative CHB demonstrated an increased number of peripheral CD8+ T cells while their peripheral blood mononuclear cells showed increased proliferation after in vitro stimulation with overlapping hepatitis B core derived peptides and an envelope derived epitope (HBs 182-191 aa), similar to those observed in acute hepatitis B. Using ICS, we found an expanded population of IFN-gamma producing T lymphocytes, CD4+ and CD8+, after non-specific stimulation, in HBeAg negative CHB compared to all other groups. HBeAg negative CHB and acute hepatitis B patients had a similarly increased number of core specific T cells measured by the IFN-gamma assays. Inactive HBsAg carriers showed minimal proliferative responses overall while they exhibited an increased number of envelope specific effector T cells (measured by ICS). In conclusion, we showed that overall CD4+ T cell responses from patients with HBeAg negative CHB were comparable to those of acute hepatitis B, while inactive HBsAg carriers despite their limited proliferative capacity the effector activity of their peripheral T cells was maintained.

Clinical and prognostic implications of self-rating depression scales and plasma B-type natriuretic peptide in hospitalised patients with chronic heart failure.

BACKGROUND: Depression is common among patients with chronic heart failure (CHF) and has been independently associated with a poorer prognosis. PURPOSE: This study evaluated the clinical and prognostic value of depression scales (Beck Depression Inventory (BDI), Zung Self-rating Depression Scale (Zung SDS)) along with plasma B-type natriuretic peptide (BNP) in CHF. METHODS: 155 hospitalised CHF patients (ejection fraction 26.9% (SD 6.4%)) were studied by depression (BDI, Zung SDS) and functional questionnaires (Kansas City Cardiomyopathy Questionnaire (KCCQ), Duke Activity Status Index (DASI)), BNP and 6-minute walk test (6MWT). Patients were followed for 6 months for cardiovascular events, including death from any cause or rehospitalisation for CHF decompensation. RESULTS: Seventy-six (49%) patients with depressive symptoms, as estimated by both scales, had significantly lower DASI and KCCQ scores (13.2 (SD 9.9) vs 23.6 (SD 13.0) and 26.6 (SD 15.0) vs 45.0 (SD 17.0), respectively; p<0.001), higher BNP (921 (SD 889) vs 439 (SD 267) pg/ml, p = 0.001) and reduced 6MWT (270 (SD 130) vs 337 (SD 133); p<0.001). According to logistic regression analysis, Zung SDS and BNP were independently associated with adverse clinical outcomes; values of Zung SDS >or=40 and of BNP >or=290 pg/ml predicted future events with a sensitivity of 82% and 94% and a specificity of 45% and 46%, respectively. The combination of Zung SDS plus BNP had an additive prognostic value, predicting events with a sensitivity of 77% and a specificity of 70% (event-free survival: Zung <40 and BNP <290 pg/ml; 170 (SD 9) days; Zung >or=40 and BNP <290 pg/ml, 159 (SD 14) days; Zung <40 and BNP >or=290 pg/ml, 118 (SD 15) days; Zung >or=40 and BNP >or=290 pg/ml, 73 (SD 8) days, p<0.001). CONCLUSIONS: CHF patients with depressive symptoms have impaired physical activity, associated with excessive neurohormonal activation. Among the studied scales, Zung SDS seemed to independently predict clinical outcome, especially in patients with increased plasma BNP concentration. Hence, the combination of those two modalities provides a practical means for risk stratification in CHF.

Kit expression in male germ cell tumors.

OBJECTIVE: KIT functions as the receptor for stem cell factor (SCF) and this interaction is essential for regulation of proliferation and survival, particularly for germ cells since it regulates oogenesis, folliculogenesis and spermatogenesis. Up-regulation of KIT signalling has been associated with oncogenic transformation in cells expressing the molecule. Our objective was to investigate the expression of KIT in germ cell tumor patients and correlate it with the patients' clinical characteristics. PATIENTS AND METHODS: One hundred and seventy-three archival blocks of formalin fixed, paraffin-embedded tumor samples from histologically confirmed germ cell tumor (GCT) patients were included in the study. Immunohistochemical staining for KIT was performed and the percentage of positive cells was calculated by an independent pathologist. KIT expression was considered as positive if > 10% of tumor cells displayed membranous or cytoplasmic staining. RESULTS: Sixty-one patients with seminomatous (49 pure, 11 anaplastic, 1 spermocytic) and 112 with non-seminomatous GCTs (36 malignant teratoma undifferentiated (MTU), 15 malignant teratoma trophoblastic (MTT), 20 malignant teratoma intermediate (MTI), 35 malignant teratoma combined (MTC) and six others) were identified. Among pure seminoma patients, 38 (77.5%) revealed a positive staining for KIT, while only two out of eleven (18.2%) anaplastic seminoma patients were identified as positive. This difference was statistically significant (p < 0.001). Among 35 patients with an MTC, 48.6% had a positive KIT staining while only two of the remaining patients with a non-seminomatous GCT had a positive staining. Although KIT was strongly correlated with seminomatous histology (p < 0.001), it failed to correlate with stage (p = 0.19) or treatment response (p = 0.11) in these patients. Overall, four (one seminoma, three MTC) out of 22 chemoresistant patients showed a positive staining for KIT. CONCLUSION: KIT is expressed in the majority of seminomas and in seminomatous components of the combined tumors, but only in a minority of anaplastic seminomas and rarely in non-seminomatous GCTs. The recent development of tyrosine kinase inhibitors may offer a possibility of cure in chemoresistant patients overexpressing KIT.

Comparison of docetaxel and docetaxel-irinotecan combination as second-line chemotherapy in advanced non-small-cell lung cancer: a randomized phase II trial.

BACKGROUND: The aim of this study was to evaluate whether docetaxel (taxotere) treatment with or without irinotecan improved patient outcomes with similar toxicity in recurrent non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Patients with recurrent platinum-refractory NSCLC with Eastern Cooperative Oncology Group performance status of 0-2 were randomized to either docetaxel 30 mg/m(2) and irinotecan 60 mg/m(2) (days 1 and 8) or docetaxel 75 mg/m(2) (day 1), both administered every 3 weeks. RESULTS: A total of 130 patients were randomized. The response rate (RR) (20% versus 14%), overall survival (6.5 months versus 6.4 months) and 1-year survival (37% versus 34%) were similar in the combination and docetaxel arms, respectively. The combination arm demonstrated a longer time to tumor progression (TTP) (5.6 versus 4.8 months; P=0.065). Grade 3-4 neutropenia and anemia were similar in the combination and docetaxel arms. Grades 3-4 non-hematological toxicity (except diarrhea) was mild and was similar in the two groups. Grade 3-4 thrombocytopenia (17% versus 6%; P=0.04) and diarrhea (12% versus 3%; P=0.05) occurred more frequently in the combination arm. CONCLUSIONS: The administration of irinotecan with docetaxel in platinum-refractory NSCLC prolonged TTP, but did not improve significantly RR, median survival or 1-year survival. Second-line docetaxel monotherapy offers significant and reproducible efficacy in platinum-refractory NSCLC.

Gemcitabine and oxaliplatin (GEMOX) in patients with cisplatin-refractory germ cell tumors: a phase II study.

BACKGROUND: To investigate the efficacy and toxicity of the combination of gemcitabine and oxaliplatin (GEMOX) in patients with relapsed or cisplatin-refractory non-seminomatous germ cell tumors (NSGCT). PATIENTS AND METHODS: Twenty-nine patients with relapsed or cisplatin-refractory NSGCT were treated with gemcitabine 1000 mg/m2 on days 1 and 8 followed by oxaliplatin 130 mg/m2 on day 1 every 3 weeks for a maximum of six cycles. Twenty-four patients (83%) were considered refractory and five (17%) absolutely refractory to cisplatin. RESULTS: Twenty-eight patients were assessable for response. Overall, nine patients (32%) achieved a favourable response (complete response, four; partial response, five). One of the complete responders relapsed after 7 months and went into disease-free status lasting for 11+ months after resection of lung metastases. The rest of the complete responders are continuously disease-free at 14+, 19+ and 28+ months with the study regimen plus or minus surgery. One of the complete responders had absolutely cisplatin-refractory disease and another one presented with a late relapse. Toxicity was primarily hematological and generally manageable: 62% of patients experienced grade 3/4 neutropenia, 10% neutropenic fever and 41% grade 3/4 thrombocytopenia. Non-hematological toxicity consisted mainly of nausea/vomiting. Three patients (10%) developed grade 3 neurotoxicity and discontinued treatment. CONCLUSIONS: The combination of GEMOX is an active, moderately toxic and easily administered regimen in patients with relapsed or cisplatin-refractory NSGCT. The 14% long-term disease-free status accomplished in this heavily pretreated patient population is quite encouraging.
