Isatuximab, Carfilzomib, Lenalidomide, and Dexamethasone for the Treatment of High-Risk Newly Diagnosed Multiple Myeloma. J Clin Oncol 2024; 42:26-37. [PMID: 37753960 PMCID: PMC10730063 DOI: 10.1200/jco.23.01696] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 08/24/2023] [Accepted: 08/31/2023] [Indexed: 09/28/2023] Open
Abstract
PURPOSE The GMMG-CONCEPT trial investigated isatuximab, carfilzomib, lenalidomide, and dexamethasone (Isa-KRd) in transplant-eligible (TE) and transplant-noneligible (TNE) patients with newly diagnosed multiple myeloma (NDMM) with exclusively high-risk disease for whom prospective trials are limited, aiming to induce minimal residual disease (MRD) negativity. METHODS This academic, investigator-initiated, multicenter, phase II trial enrolled patients with high-risk NDMM (HRNDMM) defined by mandatory International Staging System stage II/III combined with del17p, t(4;14), t(14;16), or more than three 1q21 copies as high-risk cytogenetic aberrations (HRCAs). Patients received Isa-KRd induction/consolidation and Isa-KR maintenance. TE patients received high-dose melphalan. TNE patients received two additional Isa-KRd cycles postinduction. This prespecified interim analysis (IA) reports the primary end point, MRD negativity (<10-5, next-generation flow), at the end of consolidation. The secondary end point was progression-free survival (PFS). RESULTS Among 125 patients with HRNDMM (TE-intention-to-treat [ITT]-IA, 99; TNE-ITT, 26) of the IA population for the primary end point, the median age was 58 (TE-ITT-IA) and 74 (TNE-ITT) years. Del17p was the most common HRCA (TE, 44.4%; TNE, 42.3%); about one third of evaluable TE/TNE patients presented two or more HRCAs, respectively. The trial met its primary end point with MRD negativity rates after consolidation of 67.7% (TE) and 54.2% (TNE) of patients. Eighty-one of 99 TE-ITT-IA patients reached MRD negativity at any time point (81.8%). MRD negativity was sustained for ≥1 year in 62.6% of patients. With a median follow-up of 44 (TE) and 33 (TNE) months, median PFS was not reached in either arm. CONCLUSION Isa-KRd effectively induces high rates of sustainable MRD negativity in the difficult-to-treat HRNDMM population, regardless of transplant status, translating into a median PFS that was not yet reached after 44/33 months.

Single-dose carboplatin followed by involved-node radiotherapy for stage IIA and stage IIB seminoma (SAKK 01/10): a single-arm, multicentre, phase 2 trial. Lancet Oncol 2022; 23:1441-1450. [PMID: 36228644 DOI: 10.1016/s1470-2045(22)00564-2] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 09/06/2022] [Accepted: 09/07/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND Standard treatment options for patients with stage IIA or stage IIB seminoma include either para-aortic and pelvic radiotherapy or three to four cycles of cisplatin-based combination chemotherapy. These options result in 3-year progression free survival rates of at least 90%, but bear risks for acute and late toxic effects, including secondary malignancies. We tested a novel approach combining de-escalated chemotherapy with de-escalated involved node radiotherapy, with the aim of reducing toxicity while preserving efficacy. METHODS In the single-arm, multicentre, phase 2 SAKK 01/10 trial, patients with stage IIA or IIB classic seminoma (either at primary diagnosis or at relapse during active surveillance for stage I) were enrolled at ten centres of the Swiss Group for Clinical Cancer Research and ten centres of the German Testicular Cancer Study Group. WHO performance status 0-2, age 18 years or older, and adequate bone marrow and kidney function were required for eligibility. Treatment comprised one cycle of carboplatin (area under the curve 7) followed by involved-node radiotherapy (30 Gy in 15 fractions for stage IIA disease and 36 Gy in 18 fractions for stage IIB disease). The primary endpoint was 3-year progression-free survival. Efficacy analyses were done on the full analysis set, which comprised all patients who signed the informed consent, were registered in the trial, initiated trial treatment, and met all medically relevant inclusion or exclusion criteria. Safety was assessed in all patients who were treated at least once with one of the trial treatments. The study is ongoing but no longer recruiting, and is registered with Clinicaltrials.gov, NCT01593241. FINDINGS Between Oct 18, 2012, and June 22, 2018, 120 patients were registered in the study. 116 patients were eligible and started treatment according to the study protocol (46 patients with stage IIA disease and 70 with stage IIB disease). After a median follow-up of 4·5 years (IQR 3·9-6·0), 3-year progression-free survival was 93·7% (90% CI 88·5-96·6). With a target progression-free survival of 95% at 3 years, the primary endpoint was not met. Acute treatment-related adverse events of any grade were noted in 58 (48%) of 116 patients, and grade 3 or 4 treatment-related adverse events occurred in the form of neutropenia in five (4%) patients, thrombocytopenia in three (3%) patients, and vomiting in one (1%) patient. No treatment-related deaths and no late treatment-related adverse events were reported. Serious adverse events were reported in five (4%) of 116 patients (one transient creatinine increase and four second primary tumours). INTERPRETATION Despite the fact that the primary endpoint was not met, we observed favourable 3-year progression-free survival with single-dose carboplatin area under the curve 7 and involved-node radiotherapy, with minimal toxic effects. Our findings might warrant discussion with patients about the SAKK 01/10 regimen as an alternative to standard-of-care treatment, but more research on this strategy is needed.

Outcomes of men with HIV and germ cell cancer: Results from an international collaborative study. Cancer 2021; 128:260-268. [PMID: 34592009 DOI: 10.1002/cncr.33928] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2021] [Revised: 08/08/2021] [Accepted: 08/09/2021] [Indexed: 11/08/2022]
Abstract
BACKGROUND Previous studies have shown that men with HIV and germ cell cancer (HIV-GCC) have inferior overall survival (OS) in comparison with their HIV-negative counterparts. However, little information is available on treatments and outcomes of HIV-GCC in the era of combination antiretroviral therapy (cART). METHODS This study examined men living with HIV who were 18 years old or older and had a diagnosis of histologically proven germ cell cancer (GCC). The primary outcomes were OS and progression-free survival (PFS). RESULTS Data for 89 men with a total of 92 HIV-GCCs (2 synchronous GCCs and 1 metachronous bilateral GCC) were analyzed; among them were 64 seminomas (70%) and 28 nonseminomas (30%). The median age was 36 years, the median CD4 T-cell count at GCC diagnosis was 420 cells/µL, and 77% of the patients on cART had an HIV RNA load < 500 copies/mL. Stage I disease was found in 44 of 79 gonadal GCCs (56%). Among 45 cases with primary disseminated GCC, 78%, 18%, and 4% were assigned to the good-, intermediate-, and poor-prognosis groups, respectively, of the International Germ Cell Cancer Collaborative Group. Relapses occurred in 14 patients. Overall, 12 of 89 patients (13%) died. The causes of death were refractory GCC (n = 5), an AIDS-defining illness (n = 3), and other causes (n = 4). After a median follow-up of 6.5 years, the 5- and 10-year PFS rates were 81% and 73%, respectively, and the 5- and 10-year OS rates were 91% and 85%, respectively. CONCLUSIONS The 5- and 10-year PFS and OS rates of men with HIV-GCC were similar to those reported for men with HIV-negative GCC. Patients with HIV-GCC should be managed identically to HIV-negative patients. LAY SUMMARY Men living with HIV are at increased risk for germ cell cancer (GCC). Previous studies have shown that the survival of men with HIV-associated germ cell cancer (HIV-GCC) is poorer than the survival of their HIV-negative counterparts. This study examined the characteristics, treatments, and outcomes of 89 men with HIV-GCC in the era of effective combination antiretroviral therapies. The long-term outcomes of men with HIV-GCC were similar to those reported for men with HIV-negative GCC. Patients with HIV-GCC should be managed identically to HIV-negative patients.

Abstract
5053 Background: Previous studies showed that men with HIV-associated germ cell cancer (HIV-GCC) have a similar cancer-free outcome compared with their HIV-negative counterparts. However, the overall survival (OS) was inferior and little data is available on treatment and outcome of HIV-GCC in the era of combined antiretroviral therapy (cART). Methods: Men living with HIV aged ≥ 18 years (yrs) with a diagnosis of histologically proven GCC made from 01/1996 to 07/2018 were included. Primary outcomes were OS and progression-free survival (PFS). Secondary outcomes included characteristics of GCC and HIV-infection, treatment and causes of death. Results: Data of 89 men from 23 institutions and 6 countries with a total of 92 HIV-GCC (2 synchronous and 1 metachronous bilateral GCC) were analysed, among them 64 (70%) seminomas and 28 (30%) nonseminomas. 10/89 (11%) cases were primary extragonadal GCC. Median age was 36 yrs (range, 22-52) and median time from HIV to GCC diagnosis was 5 yrs (range, 0-29). Median CD4 count at GCC diagnosis was 420 cells/µl (range, 3-1503) and 83% of pts were on cART. Stage I disease was found in 44/80 (55%) gonadal GCC (metachronous bilateral case included). Of 46 cases with stage II/III/extragonadal GCC 78%, 17% and 4% were assigned to the IGCCCG good, intermediate and poor prognosis group, respectively. Of the 44 stage I cases, 22 (50%) were followed by active surveillance, and 11 (25%) received adjuvant chemotherapy (CT) or radiotherapy. Relapses occurred in 14 pts (6 from stage I, 8 in pts primary disseminated GCC) and CT was applied to 13/14 pts, of which 3 received high-dose CT. Overall, 12/89 (13%) pts have died. Causes of death were refractory GCC (n = 5), an AIDS-defining illness (n = 3) and other (n = 4). After a median follow-up of 6.5 yrs (range, 0.3-20.9), the 5- and 10-year PFS rate was 81% and 73%, and the 5- and 10-year OS rate was 91% and 85%, respectively. There were no significant differences between the good and intermediate prognosis group or between pts with CD4 counts < 200/µl or ≥ 200/µl. Conclusions: The 5- and 10-year PFS and OS rates of men with HIV-GCC are similar to those reported for HIV-negative GCC. Pts with HIV-GCC should remain on cART and be managed in an identical fashion to HIV-negative pts.

Abstract
405 Background: Standard treatment options for stage IIA/B seminoma include either extensive paraaortal/pelvic radiotherapy or intensive chemotherapy with 3x BEP or 4x EP. Both treatment modalities are associated with excellent efficacy but also a high rate of acute and late toxicities. Therefore, de-escalation strategies appear warranted for this patient group aiming to minimize acute and long-term toxicities while maintaining efficacy. SAKK 01/10 is a joint project of the Swiss Group for Clinical Cancer Research and the German Testicular Cancer Study Group. Methods: Patients with stage IIA/B seminoma (de novo or relapse on active surveillance) were eligible for participation in this single arm phase II trial. A repeat scan was advised in patients with equivocal lymph node enlargement. Treatment consisted of one cycle carboplatin AUC7 followed by involved-node radiotherapy with 30 Gy in stage IIA and 36 Gy in stage IIB disease. The primary endpoint of the trial is 3-year progression free survival. We report on treatment compliance and early toxicity during treatment and within 30 days. Results: 120 patients with stage IIA/B seminoma were recruited from 10/12 until 06/18 in 20 study centers in Switzerland and Germany. 116 patients were eligible and initiated treatment per protocol (40% stage IIA, 60% stage IIB). All patients received chemotherapy (CT) with a median applied dose of 984 mg (range: 560-1920 mg). The median planning target volume (PTV) for radiotherapy (RT) was 297 cm3 (range: 24-1047 cm3). RT was delayed/interrupted in two patients due to adverse events. During CT, grade 2 and grade 3 adverse events were seen in 21% and 2% of all patients respectively (most common grade 2 events: neutropenia 6%, nausea 5%). During RT, grade 2 and grade 3 adverse events were seen in 26% and 6% of all patients respectively (most common grade 2 events: neutropenia 15%, nausea 6%). One case of transient creatinine increase was reported as a severe adverse event, resolving without sequelae. Conclusions: Treatment with one cycle carboplatin AUC7 and 30-36 Gy involved-node radiotherapy for stage IIA/B seminoma is feasible and demonstrates a very favorable early toxicity profile. Clinical trial information: NCT01593241.

Abstract
Standard of care for patients with symptomatic, advanced‐stage follicular lymphoma (FL) is rituximab‐containing chemoimmunotherapy followed by rituximab maintenance. This prospective, multicenter, noninterventional study analyzed how efficacy and safety data from randomized controlled trials translate into clinical practice in Germany. Both treatment‐naïve and relapsed/refractory patients with FL, who responded to rituximab‐containing induction and were scheduled for rituximab maintenance, were observed for 24 months. Effectiveness was measured by response and Kaplan‐Meier survival analysis. In addition, treatment patterns of induction and maintenance, as well as adverse events, were documented. The evaluable study population consisted of 310 first‐line patients and 173 relapsed/refractory patients, including 116 patients with initial Ann‐Arbor stage I/II and 20 patients with FL grade 3B. Regarding first‐line induction, a shift from R‐CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) to R‐bendamustine was observed over time, as well as a decline in radiotherapy. 2‐year progression‐free survival rates were 88.3% (95% confidence interval [CI] 84.0‐92.6) for first‐line patients and 76.0% (95% CI: 68.8‐83.3) for relapsed/refractory patients. Conversion from partial to complete remission (PR, CR) occurred in 53.4% of analyzed first‐line patients with PR, resulting in 69.4% CRs at study end (relapsed/refractory: conversion in 42.9%, final CRs 57.9%). Safety results were consistent with the known safety profile of rituximab in this setting. Both treatment‐naïve and relapsed/refractory patients with FL show favorable 2‐year PFS rates and improvements in the remission status with postinduction rituximab monotherapy as maintenance and consolidation therapy.

Efficacy and safety of gemcitabine, oxaliplatin, and paclitaxel in cisplatin-refractory germ cell cancer in routine care--Registry data from an outcomes research project of the German Testicular Cancer Study Group. Urol Oncol 2015; 34:167.e21-8. [PMID: 26699830 DOI: 10.1016/j.urolonc.2015.11.007] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2015] [Revised: 10/20/2015] [Accepted: 11/11/2015] [Indexed: 10/22/2022]
Abstract
BACKGROUND Chemotherapy (CTX) with gemcitabine, oxaliplatin, and paclitaxel (GOP) has demonstrated efficacy with an overall response rate (ORR) of approximately 50% in patients with multiply relapsed or cisplatin-refractory germ cell cancer (GCC) or both within a phase II study. We analyzed the efficacy and safety of GOP in routine clinical practice within a registry of the German Testicular Cancer Study Group. METHODS Overall, 63 patients with refractory GCC, who received GOP because of progression under cisplatin-based treatment or relapse after high-dose CTX, were included in this database. Patient characteristics, response rate, toxicity, progression-free and overall survival (OS) were analyzed. For further risk stratification, univariate and multivariate analyses were performed. RESULTS GOP was applied as second to eighth treatment line (median fourth) after cisplatin-based CTX. The ORR was 44% with complete remissions achieved in 8 patients (4 patients with CTX plus additional residual tumor resections and 4 patients with CTX alone) and partial remissions achieved in 19 of all for best response evaluable patients. The median progression-free survival and OS were 4.0 months (95% CI: 3.08-4.94) and 13.3 months (95% CI: 9.50-17.06), respectively. Long-term OS of>2 years was achieved in 13 (21%), and grade III and IV toxicities, mainly thrombocytopenia and leukopenia, occurred in 29 patients. CONCLUSION Our results were similar compared with the previous results from the phase II study with a distinct activity with an ORR of 44%, and a long-term OS in 21% of the patients. Our data support the recommendation to use GOP ± secondary surgery in patients with multiply refractory metastatic GCC.

Abstract
BACKGROUND Despite advances in the first- and secondline treatment of advanced breast cancer, optimal therapy thereafter remains controversial. Treatment of heavily pretreated patients is not standardized, often of low efficacy, and limited by comorbidity. In these patients, an effective treatment with low toxicity is needed. PATIENTS AND METHODS We retrospectively analyzed all metastatic breast cancer patients treated with 5-fluorouracil as continuous infusion (CI-5FU) with daily doses of 150-300 mg/m(2). RESULTS 43 patients were treated with CI-5FU until disease progression. The median number of metastatic sites was 3. Most patients were heavily pretreated with a median of 3 palliative chemotherapies (range 1-11). 42 patients were evaluable for objective response; among them 5 (12%) showed a partial response (PR) and 6 (15%) showed stable disease (SD) lasting at least 6 months, leading to a clinical benefit (CB) rate (complete response + PR + SD ≥ 6 months) of 27%. The median time to progression of patients with CB was 10 months (range 3-22). Overall survival of all patients from the start of CI-5FU was 8 months (range 1-75) and from the time of first metastases 42 months (range 9-281). Toxicity was low even in patients with hepatic insufficiency. CONCLUSION CI-5FU showed a positive efficacy/toxicity ratio. Taking into account the high number of previous treatments, it results in a remarkable CB rate of 27%.

Abstract
BACKGROUND Survival after high-dose chemotherapy (HDCT) as second-salvage treatment (SST) in multiple relapsed germ-cell tumors (GCTs). PATIENTS AND METHODS Existing databases in Berlin and Marburg of HDCT trials from 1989 to 2008 were retrospectively screened. Among 534 patients, 71 of 534 (13%) patients were scheduled for HDCT having failed previous conventional-dose first-line and first-salvage chemotherapy regimens; those 49 patients who had received at least cisplatin plus etoposide first-line as well as conventional-dose cisplatin-based first-salvage regimens and were diagnosed after 1 January 1990 were further analyzed. RESULTS Median age at SST was 32 years (range 19-52 years). Median follow-up for surviving patients was 4 years (range 1.7-8.5 years). Three of 49 (6%) patients either progressed or died before scheduled HDCT; the remaining 46 of 49 (94%) received either single or sequential HDCT. The rate of favorable responses to HDCT was 27 of 49 (55%). Nine patients remain alive and free of progression. One additional patient was lost to follow without progression at 4 years. The projected overall survival rate at 5 years was 17% (95% confidence intervals 7% to 30%). CONCLUSION HDCT can induce remissions in patients with multiple relapsed GCTs with a long-term survival rate of approximately 17%.

Abstract
5082 Background: To determine the activity of high-dose chemotherapy (HDCT) as intensification of second salvage treatment (SST) in patients with multiple relapsed germ-cell tumors (GCT). Methods: Databases in Berlin and Marburg (Germany) on patients treated with HDCT between 1989 and 2008 for germ-cell tumors were screened. Among 534 patients overall, 71/534 (13%) patients were identified as scheduled for HDCT having failed at least one previous conventional-dose first-line and first-salvage chemotherapy regimen. Forty-nine patients who had received at least cisplatin- and etoposide as first-line as well as conventional-dose cisplatin as first-salvage treatment and were diagnosed after January 1, 1990, were further analyzed. Results: Median age at SST was 32 years (range 19 to 52 years). Median follow-up for surviving patients was 4 years (range 1,7 to 8,5 years). Histology was pure seminoma in 5/49 (10%) patients and non-seminoma or mixed histologies in 44/49 (90%). The median number of cisplatin-based treatment cycles prior to SST was 7 (range 5 to 11 cycles). Three of forty-nine (6%) patients either progressed or died prior to scheduled HDCT, the remaining 46/49 (94%) received either single or sequential HDCT. The rate of favorable responses to HDCT as intensification of SST was 27/49 (55%). Ten patients are alive without progression. One additional patient is lost-to-follow at four years without progression. The projected overall survival rate at five years after initiation of SST was 17%. Conclusions: HDCT can induce long term remissions even in patients with multiple relapsed GCT. No significant financial relationships to disclose.

Abstract
e14625 TKI258 (4-amino-5-fluor-3-[5-(4-metylpiperazin-1-yl)-1H-benzimidazol-2-yl]quinolin-2(1H)-one, formerly known as CHIR258) is an ATP-competitive inhibitor with activities against class III or IV receptor kinases, which include FGFR, VEGFR, PDGFR, FLT3, and KIT. It has been demonstrated to possess strong anti-tumor and anti-angiogenetic activities in different tumor models, and, therefore, this compound is currently being clinically assessed for the treatment of diverse malignancies. In this study, we chose the breast cancer cell line MDA-MB-231, a cell line with high invasive capacities, as an in vitro model to analyze the effect and functional mechanism of TKI258 on the breast cancer invasiveness. Treatment of MDA-MB-231 cells with TKI258 resulted in reduced invasive capacities in a dose-dependent manner. In association with this effect, we observed that TKI258 down-regulated the phosphorylation of ERK1/2 and STAT3 and inhibited the VEGF production in the cell supernatants. Most interestingly, we found TKI258 had influence on the inflammatory chemokines CCL5 and CCL2 level if MDA-MB-231 cells were co-cultured with breast cancer stroma cells. We found that CCL5/CCL2 mRNA level in MDA-MB-231 cells, in stroma cells, or in co-culture of MDA-MB-231/breast cancer stroma was strongly inhibited by TKI258 as detected with real-time PCR. Parallel to this result, the dramatically elevated CCL2/CCL5 level in the media supernatants from co-cultured MDA-MB-231/stroma cells was reduced by TKI258 effectively. Furthermore, we demonstrated that the invasion-promoting effect of the tumor stroma cells was antagonized by TKI258 significantly. CCL5 stimulated invasion of MDA-MB-231 cells could be partially abrogated by TKI58 and/or by CCL5-neutralizing antibody. Therefore, it is most likely that the inhibitory effect of TKI258 on invasion of MDA-MB-231 cells in the presence of stroma cells is achieved, at least in part, by antagonizing the invasion-promoting effect of CCL5. Overall, our data show that TKI258 inhibited invasive capacities of aggressive breast cancer cell line MDA-MB-231, either in the absence or presence of tumor stroma cells in vitro.

Abstract
BACKGROUND: Leptomeningeal metastasis (LM) is a devastating complication of advanced cancer. Despite aggressive therapy survival is very poor. METHODS: Data of all breast cancer patients with LM were retrospectively analyzed (n = 27). RESULTS: Median survival was 9 weeks. Patients with contrast-enhancing meningeal lesions (n = 11) detected by MRI had a median survival of 33 weeks versus 8 weeks for patients without contrast-enhancing lesions (n = 9; p = 0.0407). Patients who received systemic chemotherapy (n = 18) had a median survival of 15 weeks versus 7 weeks (n = 9; p = 0.0106). Patients undergoing radiotherapy (n = 8) had a median survival of 17 weeks as compared to 5 weeks for patients without radiotherapy (n = 18; p = 0.0188). In a multiple Cox regression analysis, lack of systemic therapy (hazard ratio, HR 89.5; p = 0.002) and negative hormone receptor status (HR 4.2; p = 0.027) emerged as significant main risk factors, together with contrast-enhancing lesion as effect modifier for systemic therapy (p = 0.03). CONCLUSION: Contrast-enhancing meningeal lesions, systemic therapy, and radiotherapy were significantly associated with longer survival. Patients with contrast-enhancing lesions who were treated systemically had the longest survival. Evidence is increasing that systemic therapy plays an important role and should be applied in breast cancer patients with LM.

Abstract
Therapeutical hyperthermia has been considered for cancer therapy since William Coley observed tumour remission after induction of fever by bacterial toxins at the end of the 19th century. Because fever is associated with a variety of immunological reactions, it has been suspected, that therapeutical hyperthermia might also activate the immune system in a reproducible manner and thereby positively influence the course of the disease. During the last decade, new insight has been gained regarding the immunological changes taking place during therapeutic hyperthermia. In this chapter, we review the most relevant data known about the effect of hyperthermia on the immune system with special focus on alterations induced by therapeutical whole-body hyperthermia (WBH) in cancer patients.

Abstract
8632 Background: Increased proinflammatory cytokines (IL-6) and decreased brain-derived neurotrophic factor (BDNF) levels have been implicated in the pathophysiology of depression. Depression has been shown to be associated with cognitive dysfunction. The objective of this study was to assess the correlations between cognitive dysfunction, IL-6 and BDNF in cancer patients (pts) with depression. Methods: Depression was assessed in 55 patients with metastatic cancer by the Hospital Anxiety and Depression Scale (HADS) and diagnosis was established according to DSM-IV criteria. Cognitive function was assessed by the Auditory Verbal Learning Test (AVLT). Plasma concentrations of Interleukin-6 and BDNF were measured at 8 AM the same day. In the statistical analysis the Mann-Whitney test and the Pearson correlation were applied. Results: Pts characteristics (n=55): median age 60 y (25–85); 76.9% Females, 23.1% males. 52% of pts had depression. There were no significant differences in mean age or Karnofsky-index between pts with and without depression. Depression was associated with a significant higher median IL-6 level (14.8 vs. 3.7 pg/ml; p<0,001). For Cognitive function only the longterm memory was significantly reduced in depression (p=0.01). However, there was no difference in BDNF levels between both groups (p=0.164). There were correlations between HADS-D score and IL6 (r=4.11; p=0.002), IL-6 and BDNF (r= −0.42; p=0.001), BDNF and longterm memory (r=0.48; p=0.02). No correlations were found for level of depression (HADS-D score) and BDNF levels (r= −0.20; P=0.14). Conclusions: Depression and increased plasma IL-6 concentrations are strongly associated in pts with cancer. There seems to be no association between BDNF and depression in cancer pts. However there is a positive correlation between the cognitive function, at least for longterm memory, with BDNF. No significant financial relationships to disclose.

Abstract
Extreme acute physical stress leads to transient impairment of T-lymphocytes, which are essential for tumor defence and prevention of infectious diseases. Radiant whole body hyperthermia (WBH) at 41.8-42.2 degrees C may enhance the efficacy of systemic chemotherapy in patients with advanced malignancies, but is associated with marked physical stress. Aim of this study was to demonstrate stress induced short-time effects on lymphocyte subpopulations and associated cytokines during WBH. Total leukocyte count, white blood cell differential blood count, lymphocyte subpopulations (T-helper-/T4-cells, T-suppressor-/T8-cells, natural-killer-/NK-cells, gammadelta-T-cells) as well as plasma levels of Interleukin(IL)-10, IL-12 and Interferon-gamma (IFN-gamma) were measured in ten patients treated with WBH and additional cytostatic chemotherapy. Blood samples were drawn before treatment, at three temperature points during WBH, and 24 h after start of treatment. Results were compared with those obtained from a control group consisting of six patients receiving chemotherapy alone. Numbers of T4-cells decreased significantly during WBH, while numbers of NK-cells and gammadelta-T-cells increased, resulting in transient impairments of total lymphocyte counts and T4/T8-ratio. IL-12 plasma levels as well as IFN-gamma/IL-10-ratio also decreased during WBH. No significant changes were found in T8-cells of WBH patients. Changes were reversible within 24 h and could not been found in control patients. Our results support the hypothesis that WBH combined with chemo therapy induces a strong but reversible anti-inflammatory stress response in cancer patients during therapy. Further studies are necessary to examine the pathophysiological details and to evaluate the meaning of these transient immunological changes for patient's outcome.

Abstract
BACKGROUND Combinations of anthracyclines, taxanes and gemcitabine have shown high activity in breast cancer. This trial was designed to evaluate a modified combination regimen as primary chemotherapy. Non-pegylated liposomal doxorubicin (NPLD) was used instead of conventional doxorubicin to improve cardiac safety. Gemcitabine was given 72 h after NPLD and docetaxel as a prolonged infusion over 4 h in order to optimize synergistic effects and accumulation of active metabolites. PATIENTS AND METHODS Forty-four patients with histologically confirmed stage II or III breast cancer were treated with NPLD (60 mg/m(2)) and docetaxel (75 mg/m(2)) on day 1 and gemcitabine as 4-h infusion (350 mg/m(2)) on day 4. Treatment was repeated every 3 weeks for a maximum of six cycles. All patients received prophylactically recombinant granulocyte colony-stimulating factor. Patients with axillary lymph node involvement after primary chemotherapy received adjuvant treatment with cyclophosphamide, methotrexate and fluorouracil. RESULTS The clinical response rate was 80%, and complete remissions of the primary tumor occurred in 10 patients (25%). Breast conservation surgery was performed in 19 out of 20 patients (95%) with an initial tumor size of less than 3 cm and in 14 patients (70%) with a tumor size <or=3 cm. Seven patients had histologically confirmed complete responses accounting for a pCR rate of 17.5%. Expression of Ki--67 was the most important predictive parameter for response with high 38.9% breast pCR rate in patients with elevated Ki--67 expression. Although the predominant toxicity was myelosuppression with grade 3/4 neutropenia in 61% of patients few neutropenic complications resulted. Non-hematological toxicity was generally moderate with grade 3 or 4 toxicity in 10.0% of cycles. Most common non-hematologic toxicities were nausea, vomiting, alopecia, mucositis, asthenia and elevation of liver enzymes. CONCLUSION The evaluated schedule provides a safe and highly effective combination treatment for patients with early breast cancer, which is suitable for phase III studies.

Abstract
BACKGROUND Gemcitabine and vinorelbine are active agents for the treatment of metastatic breast cancer. Prolonged infusion of gemcitabine can result in higher levels of active metabolites compared to shorter administration. This phase II trial was initiated to evaluate the efficacy and tolerability of gemcitabine as prolonged infusion in combination with vinorelbine in anthracycline and/or taxane pretreated patients with metastatic breast cancer. PATIENTS AND METHODS Patients who had received one prior line of chemotherapy for metastatic disease were treated with gemcitabine (350 mg/m2 as 4 h infusion) and vinorelbine (25 mg/m2 on days 1 and 8. Treatment was repeated every 3 weeks for a maximum of six cycles. RESULTS Of 26 patients enrolled, 84% had received prior anthracycline treatment and 50% prior taxane therapy. In total, one complete and six partial responses were achieved, accounting for an overall response rate of 30.4%. The clinical benefit rate was 47.8%. Median duration of response and median time to progression were 7.3 months and 4.6 months, respectively. Median overall survival was 14.5 months. Although the predominant toxicity was myelosuppression with grade 3/4 neutropenia in 42% of patients, few neutropenic complications resulted. Non-hematological toxicity was generally moderate. Most common non-hematologic toxicities were nausea, vomiting, alopecia, peripheral neuropathy and elevation of liver enzymes. CONCLUSION Gemcitabine as prolonged infusion and vinorelbine are a safe and effective combination treatment in anthracycline and/or taxane pretreated patients. Approximately 47.8% of patients derived clinical benefit from treatment. This regimen represents a therapeutic option for patients receiving second-line therapy for metastatic breast cancer.

Abstract
The primary objective was to determine the optimal doses for gemcitabine (prolonged infusion), liposomal doxorubicin (Myocet) and docetaxel as primary (neoadjuvant) chemotherapy for locally advanced breast cancer. Secondary objectives included evaluation of the safety and efficacy of the regimen. Patients (n=19) with histologically confirmed stage II or III breast cancer were treated with liposomal doxorubicin (50-60 mg/m2) and docetaxel (60-75 mg/m2) on day 1, and gemcitabine as 4-h infusion (350-400 mg/m2) on day 4. Treatment was repeated every 3 weeks for a maximum of 6 cycles. The maximum tolerated doses were gemcitabine 350 mg/m2, liposomal doxorubicin 60 mg/m2 and docetaxel 75 mg/m2. Dose-limiting toxicities were stomatitis, diarrhea and infection. The predominant hematologic toxicity was mild-to-moderate myelosuppression with grade 3/4 neutropenia in 20% of cycles. Non-hematologic toxicity was generally mild, with no grade 4 toxicities being observed. Predominant non-hematologic toxicity was stomatitis, which occurred in 95% of patients. Grade 3 toxicities were reported for stomatitis, nausea, diarrhea, infection and constipation. No cases of cardiac, renal, pulmonary or neurotoxicity were observed. The clinical response rate was 83% and histologically confirmed, clinically complete remissions occurred in two patients (11%). We conclude that the combination of gemcitabine (prolonged infusion), liposomal doxorubicin and docetaxel is safe and highly effective in patients with locally advanced breast cancer as defined by maximum tolerated doses. The evaluated schedule is suitable for phase II studies.

Abstract
PURPOSE Intraorbital metastases of solid tumors are a rarely diagnosed clinical condition, even though pathological reports suggest an incidence of up to 30% in cancer patients. We report two cases of intraorbital, extraocular metastases in breast cancer. The first patient was a 45-year-old man who presented with diplopia, upward divergence of the left bulb, and local pain. METHODS In the standard cerebral magnetic resonance imaging (MRI) no cerebral or ocular tumor was detectable. A subsequent T1-weighted, contrast-enhanced orbital MRI with fat suppression revealed an infrabulbar mass of 18 x 13 mm in size. The second patient, a 59-year-old woman, complained of slight diplopia when looking to the left. Cerebral MRI with fat suppression showed a retrobulbar mass with 17x13 mm. In both patients metastatic breast cancer was known for several years, and both had been in a stable disease situation. Both patients were treated with stereotactic radiation, applying a cumulative dose of 35 and 45 Gy, respectively, which resulted in marked improvement of local symptoms. Most eye metastases of breast cancer are located in the choroidea, while an extrabulbar localization within the orbit is rare, with only 3-10% of all ocular metastases. Autopsy reports reveal that an estimated 10-30% of breast cancer patients develop this form of metastasis. This is in strong contrast to rare clinical case reports, suggesting frequently absent to mild clinical signs and difficult diagnosis. CONCLUSION If breast cancer patients complain of ophthalmological symptoms such as local pain, impaired vision, or diplopia, it is important to consider ocular or orbital metastatic disease.

Abstract
Whole Body Hyperthermia (WBH) has been shown to induce alterations of lymphocyte subpopulations in peripheral blood: T-cells decrease and NK-cells increase in number in the course of this therapy. As elevated temperature induces programmed cell death in healthy lymphocytes in vitro, we intended to determine the role of lymphocyte apoptosis in WBH by measuring the rate of apoptosis in blood lymphocytes in the course of this treatment. Blood was taken from cancer patients, treated with whole body hyperthermia and chemotherapy, before, during and the day after treatment. Apoptosis rates of the whole lymphocyte population, as well as, of B-, T-, CD4 + -T-, CD8 + -T-, and Natural-Killer (NK)-cell-subpopulations were determined by staining with AnnexinV-FITC and FACS flow analysis. A significant rise of apoptosis in the whole lymphocyte population, in CD4 + -T- and in CD8 + -T-cells occurred during treatment. In contrast, an elevated rate of apoptosis in NK-cells was observed 20 hours after termination of WBH. These differences were similar when the cells were incubated at 37 degrees C for 24 hours. Our results suggest, that apoptosis is one reason for the previously described decrease of T-cells during WBH and of NK-cells after WBH, and that the hyperthermia-related apoptosis-inducing mechanism is different in T-cells and NK-cells.

Abstract
In oncology, the term 'hyperthermia' refers to the treatment of malignant diseases by administering heat in various ways. Hyperthermia is usually applied as an adjunct to an already established treatment modality (especially radiotherapy and chemotherapy), where tumor temperatures in the range of 40-43 degrees C are aspired. In several clinical phase-III trials, an improvement of both local control and survival rates have been demonstrated by adding local/regional hyperthermia to radiotherapy in patients with locally advanced or recurrent superficial and pelvic tumors. In addition, interstitial hyperthermia, hyperthermic chemoperfusion, and whole-body hyperthermia (WBH) are under clinical investigation, and some positive comparative trials have already been completed. In parallel to clinical research, several aspects of heat action have been examined in numerous pre-clinical studies since the 1970s. However, an unequivocal identification of the mechanisms leading to favorable clinical results of hyperthermia have not yet been identified for various reasons. This manuscript deals with discussions concerning the direct cytotoxic effect of heat, heat-induced alterations of the tumor microenvironment, synergism of heat in conjunction with radiation and drugs, as well as, the presumed cellular effects of hyperthermia including the expression of heat-shock proteins (HSP), induction and regulation of apoptosis, signal transduction, and modulation of drug resistance by hyperthermia.

Abstract
BACKGROUND For monitoring of arterial blood pressure (ABP) during whole body hyperthermia (WBH) different methods have been recommended. This investigation was performed to evaluate the agreement of invasive measurements at various sites, and to compare invasive and non-invasive methods of ABP monitoring under conditions of a heat-induced extreme vasodilation. METHODS In 19 patients, 48 treatments with WBH were performed. Measurements of ABP in the radial and femoral artery by oscillometry and by sphygmomanometry were taken at four temperature levels during WBH (37, 40, 41.8 and 39 degrees C). RESULTS Significant differences were observed between invasive and non-invasive methods for systolic ABP, with higher values for non-invasive measurements. When compared with both invasive measurements for diastolic blood pressures, sphygmomanometry gave higher values and oscillometry gave lower values. Sphygmomanometry also showed higher values for mean ABP compared with all other techniques, while measurements in radial and femoral artery and by oscillometry only differed by approximately 5 mmHg. CONCLUSION The mean arterial pressure and not the systolic and/or diastolic pressure should guide hemodynamic management during WBH. The sphygmomanometric technique is not recommended for use during hyperthermia.
