How much platinum passes the placental barrier? Analysis of platinum applications in 21 patients with cervical cancer during pregnancy.

OBJECTIVE: Cervical cancer is the most common solid cancer diagnosed in pregnancy. Platinum is an active drug in the treatment of patients with cervical cancer. In the second and third trimesters, platinum is used to prevent cancer progression until fetal maturity is reached. However, knowledge about the transplacental passage of platinum is very limited. STUDY DESIGN: Between May 2008 and June 2014, platinum-based neoadjuvant chemotherapy was applied to 21 consecutive patients with cervical cancer diagnosed in their second trimester. At the time of delivery by cesarean delivery, synchronous samples from maternal blood, umbilical cord blood, and amniotic fluid were taken and analyzed for platinum concentrations. RESULTS: The mean week of gestation at cancer diagnosis was 17 (13-23). On average 3 (range, 2-4) cycles of chemotherapy were applied. Cesarean deliveries were carried out between 30.4 and 36.5 weeks of gestation. Twenty-two healthy babies without renal, hepatic, auditory, or hematopoietic impairment were delivered. Platinum concentrations in umbilical cord blood and amniotic fluid were 23-65% and 11-42% of the maternal blood, respectively. CONCLUSION: This series on in vivo measurement of platinum concentrations in the fetomaternal compartment observed that because of consistently lower platinum values in the fetoplacental unit, a placental filtration mechanism of platinum may be assumed.

Recurrence patterns and impact of brain metastases in synchronous single organ oligometastatic lung cancer following local ablative treatment - A multicenter analysis.

INTRODUCTION: Local ablative therapy (LAT) improves survival in oligometastatic lung cancer (OMD), but there is limited information on recurrence patterns, re-treatments and in particular the role of brain metastases during the course of disease. We therefore conducted a retrospective multicenter analysis to evaluate course of disease, sequence of therapies and predictors for long-term disease-control in the brain and survival endpoints. PATIENTS AND METHODS: Clinical data of patients with synchronous, single organ OMD with ≤4 metastases were collected from 5 certified German lung cancer centers. All patients underwent thorough initial staging including a 18FDG-PET/CT scan, brain imaging and mediastinal staging, if necessary, and received LAT to all sites of disease. RESULTS: In total, 164 patients were included (median age 62 years [range 41-84], non-squamous histology 80%, N0-1 64%, single metastasis 84%), 103 had brain (cohort A), 61 extracranial metastases (cohort B). With a median follow-up of 66 months, 115 patients (70%) experienced recurrent disease with a different distribution of sites: In cohort A vs. B, brain relapses occurred in 56% vs. 18% and new distant metastases in 5% vs. 40%. In total, LAT for every relapse was possible for 25% (29/115) of the patients. Patients with initial and secondary onset brain metastases experienced long-term disease-control in the brain and subsequently favorable survival with the application of repeated LAT (disease in the brain controlled vs. not-controlled, HR 0.21, p < 0.001). Comparable long-term overall survival was observed in patients with no or isolated brain relapses (5-years OS 74% and 92%) in contrast to patients with extracranial relapses (5-years OS 19.6%, p < 0.001). CONCLUSIONS: Repeated LAT for recurrent synchronous single organ OMD results in a long-term favorable outcome. Disease control in the brain appears crucial and likely determines survival.

Diagnosis, Therapy and Follow-up of Cervical Cancer. Guideline of the DGGG, DKG and DKH (S3-Level, AWMF Registry No. 032/033OL, May 2021) - Part 2 with Recommendations on Psycho-oncology, Rehabilitation, Follow-up, Recurrence, Palliative Therapy and Healthcare Facilities.

Aim This is an update of the interdisciplinary S3-guideline on the Diagnosis, Therapy and Follow-up of Cervical Cancer (AWMF Registry No. 032/033OL), published in March 2021. The work on the updated guideline was funded by German Cancer Aid (Deutsche Krebshilfe) as part of the German Guideline Program in Oncology. The guideline was coordinated by the German Society of Gynecology and Obstetrics ( Deutsche Gesellschaft für Gynäkologie und Geburtshilfe , DGGG) and the Working Group on Gynecological Oncology ( Arbeitsgemeinschaft Gynäkologische Onkologie , AGO) of the German Cancer Society ( Deutsche Krebsgesellschaft , DKG). Method The process used to update the 2014 S3-guideline was based on an appraisal of the available evidence using the criteria of evidence-based medicine, adaptations of existing evidence-based national and international guidelines or - if evidence was lacking - on the consensus of the specialists involved in compiling the update. After an initial review of the current literature was carried out according to a prescribed algorithm, several areas were identified which, in contrast to the predecessor version from September 2014, required new recommendations or statements which would take account of more recently published literature and the recent appraisal of new evidence. Recommendations The short version of this guideline consists of recommendations and statements on palliative therapy and follow-up of patients with cervical cancer. The most important aspects included in this updated guideline are the new FIGO classification published in 2018, the radical open surgery approach used to treat cervical cancer up to FIGO stage IB1, and the use of the sentinel lymph node technique for tumors ≤ 2 cm. Other changes include the use of PET-CT, new options in radiotherapy (e.g., intensity-modulated radiotherapy, image-guided adaptive brachytherapy), and drug therapies to treat recurrence or metastasis.

Negative enrichment by immunomagnetic nanobeads for unbiased characterization of circulating tumor cells from peripheral blood of cancer patients.

BACKGROUND: A limitation of positive selection strategies to enrich for circulating tumor cells (CTCs) is that there might be CTCs with insufficient expression of the surface target marker which may be missed by the procedure. We optimized a method for enrichment, subsequent detection and characterization of CTCs based on depletion of the leukocyte fraction. METHODS: The 2-step protocol was developed for processing 20 mL blood and based on red blood cell lysis followed by leukocyte depletion. The remaining material was stained with the epithelial markers EpCAM and cytokeratin (CK) 7/8 or for the melanoma marker HMW-MAA/MCSP. CTCs were detected by flow cytometry. CTCs enriched from blood of patients with carcinoma were defined as EpCAM+CK+CD45-. CTCs enriched from blood of patients with melanoma were defined as MCSP+CD45-. One-hundred-sixteen consecutive blood samples from 70 patients with metastatic carcinomas (n = 48) or metastatic melanoma (n = 22) were analyzed. RESULTS: CTCs were detected in 47 of 84 blood samples (56%) drawn from carcinoma patients, and in 17 of 32 samples (53%) from melanoma patients. CD45-EpCAM-CK+ was detected in pleural effusion specimens, as well as in peripheral blood samples of patients with NSCLC. EpCAM-CK+ cells have been successfully cultured and passaged longer than six months suggesting their neoplastic origin. This was confirmed by CGH. By defining CTCs in carcinoma patients as CD45-CK+ and/or EpCAM+, the detection rate increased to 73% (61/84). CONCLUSION: Enriching CTCs using CD45 depletion allowed for detection of epithelial cancer cells not displaying the classical phenotype. This potentially leads to a more accurate estimation of the number of CTCs. If detection of CTCs without a classical epithelial phenotype has clinical relevance need to be determined.

Addressing concerns about cisplatin application during pregnancy.

INTRODUCTION: Cervical cancer in second trimester of pregnancy is an oncologic challenge. Cisplatin is recommended to prevent cancer progression. This is a series correlating in vivo cisplatin concentration in the fetomaternal compartment and in breast milk with child development. METHODS: Eight consecutive patients with cervical cancer diagnosed during the second trimester underwent conization/biopsy and/or pelvic laparoscopic lymphadenectomy (LAE). Delay of pregnancy in combination with neoadjuvant monochemotherapy was performed. After 2-4 cycles of cisplatin monochemotherapy cesarean section followed by radical hysterectomy was performed above 31 weeks of gestation. Synchronous samples from maternal blood, umbilical cord blood, and amniotic fluid were taken and analyzed. A probe of breast milk was taken from three patients. Pediatric aftercare was done every three months postpartum. RESULTS: Laparoscopic LAE was uncomplicated in all patients. In seven out of eight patients lymph nodes were tumor free. Nine healthy babies were delivered. Pediatric follow-up showed normal development. Cisplatin concentrations in the umbilical cord and amniotic fluid were 31-65% and 13-42% of the amount in maternal blood, respectively. In breast milk, cisplatin was detectable in 1-10% of maternal blood concentration. CONCLUSION: Knowledge of significant lower cisplatin concentrations in fetal compartment and normal child growth provides additional security to apply cisplatin in pregnancy. Breastfeeding cannot be recommended.

The trifunctional antibody catumaxomab for the treatment of malignant ascites due to epithelial cancer: Results of a prospective randomized phase II/III trial.

Malignant ascites is a common manifestation of advanced cancers, and treatment options are limited. The trifunctional antibody catumaxomab (anti-epithelial cell-adhesion molecule x anti-CD3) represents a targeted immunotherapy for the intraperitoneal (i.p.) treatment of malignant ascites secondary to epithelial cancers. In this phase II/III trial (EudraCT 2004-000723-15; NCT00836654), cancer patients (n = 258) with recurrent symptomatic malignant ascites resistant to conventional chemotherapy were randomized to paracentesis plus catumaxomab (catumaxomab) or paracentesis alone (control) and stratified by cancer type (129 ovarian and 129 nonovarian). Catumaxomab was administered as an i.p. infusion on Days 0, 3, 7 and 10 at doses of 10, 20, 50 and 150 mug, respectively. The primary efficacy endpoint was puncture-free survival. Secondary efficacy parameters included time to next paracentesis, ascites signs and symptoms and overall survival (OS). Puncture-free survival was significantly longer in the catumaxomab group (median 46 days) than the control group (median 11 days) (hazard ratio = 0.254: p < 0.0001) as was median time to next paracentesis (77 versus 13 days; p < 0.0001). In addition, catumaxomab patients had fewer signs and symptoms of ascites than control patients. OS showed a positive trend for the catumaxomab group and, in a prospectively planned analysis, was significantly prolonged in patients with gastric cancer (n = 66; 71 versus 44 days; p = 0.0313). Although adverse events associated with catumaxomab were frequent, they were manageable, generally reversible and mainly related to its immunologic mode of action. Catumaxomab showed a clear clinical benefit in patients with malignant ascites secondary to epithelial cancers, especially gastric cancer, with an acceptable safety profile.

Cisplatin application in pregnancy: first in vivo analysis of 7 patients.

Cervical cancer in pregnancy is an oncologic challenge. Empirical cisplatin is recommended to prevent cancer progression until fetal maturity. Seven patients with cervical cancer in the second trimester decided to delay delivery together with neoadjuvant chemotherapy. After 2-4 cycles, caesarean section and radical hysterectomy were performed above 32 weeks of gestation. Synchronous samples from maternal blood, umbilical cord blood and amniotic fluid were taken. All patients delivered healthy babies. Cisplatin concentrations in umbilical cord and amniotic fluid were 31-65 and 13-42% of the maternal blood, respectively. This is the first series on in vivo cisplatin concentration in the fetomaternal compartment.

Remission of extensive intrahepatic metastasis by C-arm computed tomography guided chemoembolization in uveal melanoma.

As soon as uveal melanoma has metastasized to the liver, response rates to systemic chemotherapy are low. It can be improved by development of special locoregional procedures. A 24-year-old woman suffered from inoperable hepatic metastases which grew to life-endangering size despite both systemic chemotherapy with gemcitabine/treosulfan and conventional intrahepatic chemoembolization with fotemustine and starch particles. We subsequently performed two angiographic C-arm CT-guided, superselective chemoembolizations of the hepatic arteries feeding the tumor, using cisplatin, starch microspheres and ethiodized oil. Following this treatment, no vital tumor tissue was detectable by MRI. This remission lasted for more than 6 months and the patient's quality of life was good. A subsequent local relapse could not be treated with chemoembolization because of thrombosis of the portal vein due to tumor compression. And the patient died 20 months after first detection of metastases. However, the selective angiographic C-arm CT-guided chemoembolization resulted in prolongation of life with good quality despite the advanced stage of the disease.

Controversies in the treatment of advanced stages of small cell lung cancer.

Small cell lung cancer is a highly proliferative tumor with the potential of early hematogeneous spread. At the time of first diagnosis more than 80% of patients present with distant metastases. Although response rate to chemotherapy is high with > 50% confirmed objective responses, the majority of patients relapse within several months after first-line chemotherapy. The combination of cisplatin plus etoposide has become standard chemotherapy. In contrast to early stages, equal efficacy of cisplatin and carboplatin in combination with etoposide has been suggested in advanced disease in two randomized trials in the 1990s. Newer agents like the topoisomerase I inhibitors topotecan and irinotecan have been investigated for first line treatment. Two phase III studies demonstrated similar efficacy of topotecan when compared to etoposide. Results of first line therapy with irinotecan are more contradictory. A first trial demonstrated superiority of irinotecan/cisplatin over etoposide/cisplatin in a Japanese population. However, two subsequent North American phase III trials showed equivalent efficacy. Recently a Scandinavian phase III trial found superiority of irinotecan/carboplatin over etoposide/carboplatin. Prophylactic cranial irradiation (PCI) after first line chemotherapy has become standard of care in advanced stages, because a randomized phase III trial of the EORTC demonstrated a survival benefit. Second-line therapy in relapsed disease improves survival. A randomized trial showed similar efficacy of topotecan when compared to anthracyline containing chemotherapy, with an improvement of cancer related symptoms in the topotecan arm.

Should irinotecan or etoposide be used in combination with carboplatin for small cell lung cancer?

Little progress has been made in the treatment of small cell lung cancer over the past two decades. Superiority of combined irinotecan-cisplatin over standard etoposide-cisplatin in a Japanese phase III trial was not confirmed in two subsequent US studies. In this Practice Point we discuss a randomized, phase III trial by Hermes and colleagues, which included 220 patients with extensive-disease small cell lung cancer and showed superiority of carboplatin-irinotecan versus carboplatin-oral etoposide. In this trial, 47% of patients had a performance status > or = 3 and 35% were older than 70 years, which represents a typical clinical practice population of patients; however, oral administration of etoposide and an arbitrary dose reduction in elderly and unfit patients represent limitations of the study. A European trial of irinotecan-carboplatin versus intravenous etoposide-carboplatin has completed accrual and results will be analyzed in 2009. Although the results of the study by Hermes et al. are of interest, substitution of etoposide by irinotecan can not be recommended.

Bowel perforation in non-small cell lung cancer after bevacizumab therapy.

BACKGROUND: Bevacizumab is increasingly used in combination with chemotherapy for treatment of unresectable non-small cell lung cancer. The aim of this report is to underline possible risks associated with this otherwise well-tolerated drug. PATIENT: A 69-year-old patient with metastatic non-small cell lung cancer was started on a palliative chemotherapy regimen containing carboplatin, paclitaxel, and bevacizumab. RESULTS: After the second cycle of chemotherapy, the patient developed abdominal pain. On emergency laparotomy, there was diffuse perforation of the colonic wall, so the patient underwent a Hartmann's procedure with subtotal colectomy. Histopathological examination confirmed the diagnosis of ischemic colitis. CONCLUSION: Gastrointestinal perforation is a known adverse event of bevacizumab therapy which so far has occurred only in patients with predisposing risk factors. Our patient illustrates that there must always remain a high index of suspicion regarding bowel perforation in patients developing acute abdominal pain under bevacizumab therapy, even if they have no apparent risk factors.

Sunitinib treatment for patients with advanced clear-cell renal-cell carcinoma after progression on sorafenib.

BACKGROUND: Sorafenib and sunitinib are tyrosine kinase inhibitors with largely overlapping specificities, approved for the treatment of metastatic renal-cell carcinoma (RCC). It was unclear whether the similarities of the two drugs would lead to complete cross-resistance, or whether sequential application would be efficacious. METHODS: Patients with metastatic RCC and progression on sorafenib treatment were treated with repeated cycles of sunitinib, 50 mg for 4 weeks, followed by a 2-week break. Response (Response Evaluation Criteria in Solid Tumors, RECIST) was assessed every second cycle. RESULTS: A total of 22 patients with progression on sorafenib were accrued. Initially, sorafenib treatment was efficacious in all patients, with 7 showing partial response (PR) and 15 stable disease (SD), and subsequent disease progression. With 4 PRs (18%) and 12 SD (55%) a disease control rate of 73% was achieved. The median progression-free survival (PFS) on sunitinib was 21.5 weeks; median overall survival (OS) was not reached. Estimated 1-year PFS and OS were 31 and 60%, respectively. There was no apparent relationship between response to sorafenib and outcome on sunitinib. CONCLUSION: In our cohort of patients with RCC and progression after initial efficacy of sorafenib, the efficacy data of second-line sunitinib were close to published results of first-line treatment, suggesting limited clinically relevant cross-resistance.

Phase II study of plitidepsin in pretreated patients with locally advanced or metastatic non-small cell lung cancer.

OBJECTIVE: To evaluate the progression-free rate (PFR) at 3 months (13+/-1 weeks), antitumor response, time-to-event efficacy endpoints, and toxicity profile of plitidepsin administered as a 3-h continuous i.v. infusion at a dose of 5mg/m(2), every 2 weeks, to patients with chemotherapy pretreated advanced non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: This was a multicenter, non-randomized, exploratory, phase II study. Treatment lasted until disease progression, unacceptable toxicity, patient refusal or treatment delay for >2 weeks. PFR (primary efficacy endpoint) and objective response rate (secondary efficacy endpoint) were evaluated according to RECIST, while the toxic profile of plitidepsin was assessed using the NCI-CTC, version 2.0. RESULTS: A total of 21 patients with a median age of 61 years and with locally advanced or metastatic non-resectable NSCLC, who had previously received only one line of chemotherapy in an advanced setting, received a total of 54 cycles of treatment (median of two cycles per patient; range: 1-8). Antitumor activity was seen in 3 (1 PR, 2 SD) out of 17 evaluable patients according to RECIST. One patient was responder for the primary (PFR at 13+/-1 weeks) and secondary efficacy endpoint (stable disease according to RECIST). Other two patients were non-responders for the primary efficacy endpoint, but had stable disease (not confirmed at weeks 13+/-1 due to previous withdrawal due to adverse events). With a median follow-up of 12.3 months, the median time to progression (TTP) and the median overall survival (OS) were 1.2 months and 4.3 months, respectively. The incidence of plitidepsin-related toxicities was low and most of them were mild-to-moderate in severity. The most common side effects were anemia, and asymptomatic and non-cumulative increases of gamma-glutamyltransferase (GGT) and liver transaminase levels. CONCLUSION: This study shows that plitidepsin 3-h continuous i.v. infusion (5mg/m(2)) every 2 weeks, was feasible and well tolerated in patients with pretreated NSCLC. The lack of evidence of antitumor activity precludes further studies with this plitidepsin schedule in this tumor setting.

Circulating tumor cells as prognostic factor for distant metastases and survival in patients with primary uveal melanoma.

PURPOSE: The aim of this study was to determine in patients with high-risk primary uveal melanoma whether the detection of circulating tumor cells by quantitative reverse transcription-PCR (RT-PCR) is of prognostic relevance. EXPERIMENTAL DESIGN: Blood samples from 110 patients with high-risk nonmetastatic uveal melanoma were collected on the occasion of primary treatment or follow-up visit. mRNA expression of tyrosinase and MelanA/MART1 were analyzed by real-time RT-PCR and compared with clinical data at presentation and follow-up by univariate and multivariate analyses. RESULTS: The RT-PCR assay yielded a positive result in 11 of 110 patients, with five positive findings for tyrosinase and five for MelanA/MART1, and one sample positive for both markers. At a median follow-up of 22 months, 25% of patients had developed metastases and 15% had died. Univariate statistical analysis revealed RT-PCR and the largest tumor diameter as important prognostic factors for the development of metastases and for survival. In a Cox proportional hazard model, RT-PCR result and largest tumor diameter predicted metastases (hazard ratios 7.3 and 2.6, respectively), whereas PCR result, largest tumor diameter, and Karnofsky performance status were significant variables for disease-specific survival (hazard ratios 22.6, 4.7, and 6.0, respectively). Analysis of individual RT-PCR results revealed both tyrosinase and MelanA/MART1 transcripts as independent prognostic factors. CONCLUSION: The presence of tyrosinase or MelanA/MART1 transcripts is an independent prognostic factor in patients with high-risk primary uveal melanoma for subsequent development of metastases and for survival and can be used to select patients for adjuvant treatment studies.

CabaGast: multicentre, Phase II study with cabazitaxel in previously treated patients with advanced or metastatic adenocarcinoma of the esophagogastric junction and stomach.

INTRODUCTION: This is a single-arm study (NCT01956149) to determine the prolonged (≥ 4 months) disease control rate with cabazitaxel administered in second-(or later) setting for patients with advanced or metastatic adenocarcinoma of the esophagogastric junction (EGJ) and stomach. METHODS: 65 patients with advanced EGJ and stomach cancer were treated with 20 mg/m2 cabazitaxel every 3 weeks for a maximum of six cycles. The main objective of the study is a prolonged disease control rate (pDCR: CR, PR or SD lasting at least 4 months). Secondary outcome measures were overall survival, progression-free survival, response rate by subgroup (with vs without previous treatment with a taxane) and toxicity. Patients were assessed for tumor response every 6 weeks during therapy and during the follow-up (up to 12 months). RESULTS: 65 patients (median age: 63, range 31-86 years) were assigned to treatment. Median no. of prior therapies that had received prior taxane therapy was 2. 80%. Patients received a median of two cycles of cabazitaxel. Efficacy results are for the ITT population. The mDCR in n = 65 patients was 10.8% (95% CI 4.4-20.9%). There was a control of disease (CR + PR + SD) in n = 26 patients of n = 65, corresponding to a DCR of 40.0% (95% CI 28.0-52.9%). In patients without prior taxane use, it was 46.2% (95% CI 25.1-80.8%) and in patients with only one prior therapy, DCR was 50.0% (95% CI 31.3-68.7%). The median overall survival was 4.6 months (95% CI 3.16, 5.59) in the whole ITT population. In patients with only one prior therapy, median OS was 5.4 months (95% CI 2.60, 7.43) and in patients without taxane pretreatment, it was 6.4 months (95% CI 1.38, 14.17). The median progression-free survival time was 1.5 months (95% CI 1.32, 2.27) in the whole ITT population, 2.9 months (95% CI 0.72, 4.67) without prior taxane therapy and was 1.7 (95% CI 1.28, 3.35) months in patients with only one prior therapy median. CONCLUSIONS: Cabazitaxel is active in heavily pretreated patients with metastatic and advanced esophagogastric junction and gastric adenocarcinoma. Efficacy results in a classic second-line population are comparable to other second-line studies, therefore, under the limitations of this trial, (single arm, Phase II design) cabazitaxel might be an option especially in patients without prior taxane therapy, in second line and even further line therapy of metastatic and advanced esophagogastric junction and gastric adenocarcinoma.

Local ablative treatment for synchronous single organ oligometastatic lung cancer-A propensity score analysis of 180 patients.

INTRODUCTION: Local ablative treatment (LAT) improves outcome in lung cancer with oligometastatic disease (OMD) and potentially leads to long term survival. The aim of this retrospective study was to evaluate and quantify the additional benefit of LAT in synchronous OMD and to further identify prognostic factors for survival. PATIENTS AND METHODS: A propensity score-matched pairs analysis was performed on a set of patient and disease variables in 180 patients, treated for synchronous single organ OMD including non small-cell and neuroendocrine lung cancer with ≤4 metastases between 2000 and 2016 in 3 lung cancer centers in Berlin, Germany. Patients either received LAT for all sites of disease (intervention group) by means of surgery or stereotactic radiotherapy, or standard chemotherapy, if necessary combined with a local treatment with palliative intent (control group). RESULTS: Median follow-up time was 32.2 and 18.8 months for the intervention and control group, respectively. Substantial benefits in median progression-free survival (PFS, 25.1 vs. 8.2 months; HR, 0.30; 95% CI, 0.21-0.43; p < 0.001) and overall survival (OS, 60.4 vs. 22.5 months; HR, 0.42; 95% CI, 0.28-0.62; p < 0.001) were associated with LAT. Histology of adenocarcinoma and T1a primaries also predicted a favorable prognosis concerning PFS and OS. More favorable nodal stage (N0-2 vs. 3) and solitary metastases were associated with an extended PFS, whereas initial ECOG-PS (0-1 vs. 2) predicted OS. CONCLUSIONS: LAT was the strongest predictor for PFS and OS in OMD with ≤4 metastases. Survival in the control group identifies OMD as a subset of lung cancer with a generally more favorable prognosis.

Phase II trial of second-line bendamustine chemotherapy in relapsed small cell lung cancer patients.

PURPOSE: The efficacy and toxicity of bendamustine chemotherapy in relapsed small cell lung cancer (SCLC) was determined in this phase II trial. PATIENTS AND METHODS: Patients with cytologically or histologically proven SCLC, who had a sensitive relapse, which was defined as a relapse>or=2 months after completion of primary therapy, were eligible for this study. After informed consent patients received 120 mg/m2 of bendamustine on Days 1 and 2 every 3 weeks. A maximum of six cycles was administered. Primary endpoint was response rate, secondary endpoints included toxicity, progression free survival and overall survival (OS). RESULTS: Twenty-one patients with a median age of 59 years (range 47-76) were accrued to this trial. Six (29%) of 21 patients achieved a confirmed partial remission, 6 (29%) had stable disease and 9 (42%) patients progressed according to RECIST criteria. Median progression free survival was 4 months (95% CI 0-8, 3), median overall survival was 7 months (95% CI 5, 8-8, 2). One- and 2-year survival was 16% and 8%, respectively. Grade III/IV neutropenia occurred in 3 (15%) of 21 patients, 1 patient had a lethal Gram-negative sepsis in neutropenia. Two additional patients had pneumonia in the absence of neutropenia. Two patients (10%) had a grade III anemia, no grade III or IV thrombocytopenia was observed. CONCLUSION: This trial demonstrates efficacy of bendamustine in relapsed SCLC and a favourable toxicity profile. Therefore, single-agent bendamustine is a treatment option for patients with SCLC, who have responded to initial platinum containing chemotherapy and should further be investigated in randomized trials.

A phase I/IIa clinical trial of CLAOP21 and CLAOP14 in patients with high grade non-Hodgkins lymphoma.

This study was performed to investigate hematotoxicity and occurrence of PPE in patients with high-grade non-Hodgkins lymphoma treated with a modified CHOP regimen (CLAOP), where doxorubicin had been substituted by a noncardiotoxic pegliposomal doxorubicin. An open-label phase I/IIa study was performed evaluating CLAOP21/20 with 20 mg/m(2) of pegliposomal doxorubicin every 21 days (12 patients), and a dose-dense filgrastim supported CLAOP14 regimen every 14 days with escalating doses of pegliposomal doxorubicin (24 patients) in elderly high-grade lymphoma patients or patients with comorbidity interfering with cardiac function. CLAOP21/20 was well tolerated. Hematotoxicity was similar to that reported with regular CHOP. In the CLAOP14 cohort, a pegliposomal doxorubicin dose of 25 mg/m(2) was associated with dose-limiting hematotoxicity, febrile episodes, and PPE. Both regimens were active with an overall response rate of 60% and 77%, respectively. The recommended dose of pegliposomal doxorubicin in the biweekly regimen for Phase II/III testing is 20 mg/m(2).

A Patient with Non-Hodgkin Lymphoma and Nonspecific Interstitial Pneumonia during Ibrutinib Therapy.

We present a 74-year-old male with nonspecific interstitial pneumonia (NSIP) during treatment with ibrutinib for mantle cell lymphoma. Previously, the patient had received six cycles of bendamustine and rituximab and six cycles of R-CHOP, followed by rituximab maintenance therapy. Respiratory tract complications of ibrutinib other than infectious pneumonia have not been mentioned in larger trials, but individual case reports hinted to a possible association with the development of pneumonitis. In our patient, the onset of alveolitis that progressed towards NSIP together with the onset of ibrutinib treatment suggests causality. One week after ibrutinib was discontinued, nasal symptoms resolved first. A follow-up CT showed a reduction in the reticular hyperdensities and ground-glass opacities, suggestive of restitution of the lung disease. To our knowledge, this is the first case showing a strong link between ibrutinib and interstitial lung disease, strengthening a previous report on subacute pneumonitis. Our findings have clinical implications because pulmonary side effects were reversible at this early stage. We, therefore, suggest close monitoring for respiratory side effects in patients receiving ibrutinib.
