INOVATYON/ ENGOT-ov5 study: Randomized phase III international study comparing trabectedin/pegylated liposomal doxorubicin (PLD) followed by platinum at progression vs carboplatin/PLD in patients with recurrent ovarian cancer progressing within 6-12 months after last platinum line.

BACKGROUND: This trial investigated the hypothesis that the treatment with trabectedin/PLD (TP) to extend the platinum-free interval (TFIp) can improve overall survival (OS) in patients with recurrent ovarian cancer (OC). METHODS: Patients with OC (up to two previous platinum-based lines), with a TFIp of 6-12 months, were randomised to receive carboplatin/PLD (CP) or TP followed by platinum therapy at relapse. The primary endpoint was OS (HR: 0.75). RESULTS: The study enrolled 617 patients. The median TFIp was 8.3 months and 30.3% of patients had received two previous platinum lines. 74% and 73.9% of patients, respectively, received a subsequent therapy (ST) in the CP and TP arm; in the latter TP arm 87.2% of ST was platinum-based, as per protocol. The median OS was 21.4 for CP and 21.9 months for TP (HR 1.13; 95% CI: 0.94-1.35; p = 0.197). Grade 3-5 adverse reactions occurred in 37.1% of patients in the CP arm and 69.7% of patients in the TP arm, and the most frequent were neutropenia (22.8% CP, 39.5% TP), gastrointestinal (7.1% CP, 17.4% TP), hepatic (0.7% CP, 19.1% TP). CONCLUSIONS: This study did not meet the primary endpoint. CP combination remains the standard for patients with recurrent OC and a 6-12 months TFIp; TP is an effective treatment in patients suffering from persistent platinum toxicities. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, number NCT01379989.

Efficacy and safety of durvalumab with olaparib in metastatic or recurrent endometrial cancer (phase II DOMEC trial).

BACKGROUND: Patients with advanced endometrial cancer have a poor prognosis, and treatment options are limited. The investigator-initiated, multicenter, phase II DOMEC trial (NCT03951415) is the first trial to report data on efficacy and safety of combined treatment with PD-L1 and PARP inhibition for advanced endometrial cancer. PATIENTS AND METHODS: Patients with metastatic or recurrent endometrial cancer were enrolled. Patients received durvalumab 1500 mg intravenously q4w and olaparib 300 mg 2dd until disease progression, unacceptable toxicity, or patient withdrawal. Patients with at least 4 weeks of treatment were evaluable for analysis. The primary endpoint was progression-free survival at 6 months. Evidence for efficacy was defined as progression-free survival at 6 months in ≥50% of patients. Secondary endpoints included safety, objective response and overall survival. RESULTS: From July 2019, through November 2020, 55 patients were enrolled. At data cut-off (September 2021), 4 of the 50 evaluable patients were still on treatment. Seventeen patients (34%) were progression-free at 6 months. Objective response rate was 16% (95% CI, 8.3 to 28.5) with 1 complete and 7 partial responses. With a median follow-up of 17.6 months, median progression-free survival was 3.4 months (95% CI, 2.8 to 6.2) and median overall survival was 8.0 months (95% CI, 7.5 to 14.3). Grade 3 treatment-related adverse events occurred in 8 patients (16%), predominantly anemia. There were no grade 4 or 5 treatment-related adverse events. CONCLUSION: The combination of durvalumab and olaparib was well tolerated, but did not meet the prespecified 50% 6-month progression-free survival in this heterogeneous patient population with advanced endometrial cancer.

Intraperitoneal treatment for advanced ovarian cancer, the Dutch experience. What did we learn?

BACKGROUND: Combined administration of intravenous (iv) and intraperitoneal (ip) (iv/ip) chemotherapy is an effective adjuvant treatment option after primary debulking surgery (PDS) for advanced ovarian cancer (OC). Increased toxicityand patient burden limit its use in daily practice. OBJECTIVE: To assess toxicity and survival outcomes of iv/ip chemotherapy in daily practice in the Netherlands. METHODS: This retrospective cohort study included 81 women who underwent at least an optimal PDS for FIGO stage III OC followed by iv/ip chemotherapy according to the Armstrong regimen, in four hospitals in the Netherlands between January 2007 and May 2016. We collected information on surgical procedure, abdominal port implantation, toxicity, and recurrence-free and overall survival. RESULTS: All participants underwent PDS, of whom 60 (74%) had their ip catheter implanted during PDS. Most frequently reported all grade toxicity was haematological n = 44 (54%). Forty-four patients (54%) completed all six cycles of iv/ip chemotherapy. The most frequent causes of discontinuation of iv/ip administration were renal dysfunction (12/37 = 32%) and catheter problems (7/37 = 19%). Median recurrence-free survival and overall survival were 24 months (range 0 - 108) and 80 months (range 4-115), respectively. Surgical outcome, completion of more than three courses of treatment and intra-abdominal localisation of recurrent disease were associated with better survival outcomes. CONCLUSION: In daily practice, 54% of patients with advanced OC could complete all scheduled cycles of iv/ ip chemotherapy with acceptable morbidity and toxicity, leading to outcomes comparable with the results of published trials on iv/ip chemotherapy.

MetaMap: an atlas of metatranscriptomic reads in human disease-related RNA-seq data.

Background: With the advent of the age of big data in bioinformatics, large volumes of data and high-performance computing power enable researchers to perform re-analyses of publicly available datasets at an unprecedented scale. Ever more studies imply the microbiome in both normal human physiology and a wide range of diseases. RNA sequencing technology (RNA-seq) is commonly used to infer global eukaryotic gene expression patterns under defined conditions, including human disease-related contexts; however, its generic nature also enables the detection of microbial and viral transcripts. Findings: We developed a bioinformatic pipeline to screen existing human RNA-seq datasets for the presence of microbial and viral reads by re-inspecting the non-human-mapping read fraction. We validated this approach by recapitulating outcomes from six independent, controlled infection experiments of cell line models and compared them with an alternative metatranscriptomic mapping strategy. We then applied the pipeline to close to 150 terabytes of publicly available raw RNA-seq data from more than 17,000 samples from more than 400 studies relevant to human disease using state-of-the-art high-performance computing systems. The resulting data from this large-scale re-analysis are made available in the presented MetaMap resource. Conclusions: Our results demonstrate that common human RNA-seq data, including those archived in public repositories, might contain valuable information to correlate microbial and viral detection patterns with diverse diseases. The presented MetaMap database thus provides a rich resource for hypothesis generation toward the role of the microbiome in human disease. Additionally, codes to process new datasets and perform statistical analyses are made available.

[Making better use of the clinical geneticist's expertise; treating physician could request a DNA test for most cancer patients]. / Expertise van klinisch geneticus beter benutten.

Eight university medical centres in the Netherlands have established clinical genetic services. Patients receive intensive, and therefore costly, genetic counselling before genetic testing takes place. In recent years the number of patients referred to clinical genetic services has risen dramatically, creating waiting-list backlogs. Knowing your carrier status in hereditary cancers, for instance for a BRCA1/2 mutation, can have consequences for surveillance, treatment, and prevention; however, 90% of patients with breast cancer do not have a mutation. We, therefore, argue that the pathway to genetic testing should be reconstructed in order to safeguard timely and adequate genetic testing for an increasing number of patients. The treating physician should be able to request a DNA test in carefully-selected patient-populations, and only refer patients for genetic counselling after a positive finding. Prerequisites for this 'mainstream pathway' are adequate training for medical specialists, good communication with genetics' departments, and guaranteed referral in uncertain or complex cases.

The effect of hearing loss on source-distance dependent speech intelligibility in rooms.

Westermann and Buchholz [(2015). J. Acoust. Soc. Am. 137(2), 757-767] found substantial improvements in speech reception thresholds (SRTs) for normal hearing listeners in a reverberant auditorium when the target talker was separated in distance from a two-talker masker. This study applied similar methodology, but tested listeners with a hearing impairment. On average, the participants received a 7 dB benefit in SRTs when the target was fixed at 0.5 m and the masker was moved from 0.5 to 10 m. But when the target was moved away, the SRTs increased by 5 dB. This indicates that hearing impaired listeners have difficulties suppressing nearby maskers while focusing attention on a far target.

Fifth Ovarian Cancer Consensus Conference of the Gynecologic Cancer InterGroup (GCIG): clinical trial design for rare ovarian tumours.

This manuscript reports the consensus statements on designing clinical trials in rare ovarian tumours reached at the fifth Ovarian Cancer Consensus Conference (OCCC) held in Tokyo, November 2015. Three important questions were identified concerning rare ovarian tumours (rare epithelial ovarian cancers (eOC), sex-cord stromal tumours (SCST) and germ cell tumours (GCT)): (i) What are the research and trial issues that are unique to rare ovarian tumours? There is a lack of randomised phase III data defining standards of care which makes it difficult to define control arms, but identifies unmet needs that merit investigation. Internationally agreed upon diagnostic criteria, expert pathological review and translational research are crucial. (ii) What should be investigated in rare eOC, GCT and SCST? Trials dedicated to each rare ovarian tumour should be encouraged. Nonetheless, where the question is relevant, rare eOC can be included in eOC trials but with rigorous stratification. Although there is emerging evidence suggesting that rare eOC have different molecular profiles, trials are needed to define new type-specific standards for each rare eOC (clear cell, low grade serous and mucinous). For GCTs, a priority is reducing toxicities from treatment while maintaining cure rates. Both a robust prognostic scoring system and more effective treatments for de novo poor prognosis and relapsed GCTs are needed. For SCSTs, validated prognostic markers as well as alternatives to the current standard of bleomycin/etoposide/cisplatin (BEP) should be identified. (iii) Are randomised trials feasible? Randomised controlled trials (RCT) should be feasible in any of the rare tumours through international collaboration. Ongoing trials have already demonstrated the feasibility of RCT in rare eOC and SCST. Mucinous OC may be considered for inclusion, stratified, into RCTs of non-gynaecological mucinous tumours, while RCTs in high risk or relapsed GCT may be carried out as a subset of male and/or paediatric germ cell studies.

An impressive response to pazopanib in a patient with metastatic endometrial carcinoma.

The incidence of endometrial carcinoma is rising and the patients with distant metastases have a poor prognosis, especially when progression of disease occurs after systemic treatment with hormonal therapy or chemotherapy. Pazopanib, a multi-targeted inhibitor of several oncogenic receptor tyrosine kinases, has been investigated in patients with chemotherapy-resistant endometrial carcinoma or patients for whom chemotherapy is contraindicated. In this report we will describe a spectacular response to pazopanib in a patient with recurrent metastatic endometrial carcinoma.

[Effects of Reactive Jump Training in Handball Players Regarding Jump Height and Power Development in the Triceps Surae Muscle]. / Trainingseffekte eines reaktiven Sprungkrafttrainings bei Handballern in Bezug auf die Sprunghöhe und die Kraftentfaltung des Musculus triceps surae.

BACKGROUND: Studies have shown changes in the technical and physical demands in modern handball. The game has increased considerably in speed, power and dynamics. Jump training has, therefore, become ever more important in the training of the athletes. These developments contribute to the fact that handball is now one of the most injury-prone types of sport, with the lower extremities being most frequently affected. Reactive jump training is not only used in training by now, but also increasingly in injury prevention. The aim of this study was to investigate the effectiveness of reactive jump training with handball players. MATERIAL AND METHODS: 21 regional league handball players were randomly divided into an intervention group (n = 12) and a control group (n = 9). The intervention group completed a six-week reactive jump training programme while the control group went through a non-specific training programme. Jump height (squat and counter movement jump), isokinetic and isometric maximum power as well as muscle activity served as measuring parameters. RESULTS: A comparison of the intervention and control groups revealed that the reactive jump training led to significant improvements in jump height. The isometric and isokinetic maximum power measurements and the electromyographic activities of the triceps surae muscle demonstrated an improvement in the values within the intervention group. However, this improvement was not significant compared with the control group. Likewise both jumps correlated with the muscle activity of the soleus muscle as shown by electromyography. A moderate correlation was noticed between the isokinetic maximum power measurement and the electromyographic activity of the soleus and gastrocnemius medialis muscles. Furthermore, the correlations of the isometric and isokinetic maximum power meas-urements resulted in a strong correlation coefficient. CONCLUSION: This study revealed a significant increase in jump height after reactive jump training. There was no significant difference in power development between the two groups. However, we were able to demonstrate correlations which would make it seem reasonable and interesting to investigate the question more closely. An interesting field of research could be the question of the effectiveness of reactive jump training in the areas of rehabilitation and injury prevention.

[Tinea barbae profunda by Arthroderma benhamiae. A diagnostic challenge]. / Tinea barbae profunda durch Arthroderma benhamiae. Eine diagnostische Herausforderung.

Dermatomycoses due to pets and farm animals are often a clinical and diagnostic challenge for dermatologists. A 24-year-old man presented with inflammatory skin changes on his cheeks and chin. Because of negative fungal culture and the clinical appearance of a highly inflammatory process, our first diagnosis was a bacterial pyoderma. Polymerase chain reaction (PCR) identified Arthroderma benhamiae in both the patient and his guinea pig. A. benhamiae is a zoophilic dermatophyte which belongs to the Trichophyton mentagrophytes-complex. The fungus is acquired from guinea pigs and causes highly inflammatory forms of tinea. PCR-based diagnostics are quick and simple tools to identify this pathogen, so that suitable antimycotic therapy can be initiated quickly.

Comparing cisplatin-based combination chemotherapy with EMA/CO chemotherapy for the treatment of high risk gestational trophoblastic neoplasia.

BACKGROUND: Cisplatin-based chemotherapy (etoposide 100 mg/m(2) days 1-5, methotrexate 300 mg/m(2) day 1, cyclophosphamide 600 mg/m(2) day 1, actinomycin D 0.6 mg/m(2) day 2 and cisplatin 60 mg/m(2) day 4, EMACP) was compared to EMA/CO (etoposide 100 mg/m(2) days 1-2, methotrexate 300 mg/m(2) day 1 and actinomycin D 0.5 mg i.v. bolus day 1 and 0.5 mg/m(2) day 2, alternating with cyclophosphamide 600 mg/m(2) day 8 and vincristine 1 mg/m(2) day 8) for the treatment of high-risk gestational trophoblastic neoplasia (GTN). PATIENTS AND METHODS: In the Netherlands, 83 patients were treated with EMACP and 103 patients with EMA/CO. Outcome measures were remission rate, median number of courses to achieve normal human chorionic gonadotrophin (hCG) concentrations, toxicity, recurrent disease rate and disease specific survival. RESULTS: Remission rates were similar (EMACP 91.6%, EMA/CO 85.4%). The median number of courses of EMA/CO to reach hCG normalisation for single-agent resistant disease and primary high-risk disease was three and five courses, respectively, compared to 1.5 (p=0.001) and three (p<0.001) courses of EMACP. Patients treated with EMACP more often developed fever, renal toxicity, nausea and diarrhoea compared to patients treated with EMA/CO. Patients treated with EMA/CO more often had anaemia, neuropathy and hepatotoxicity. CONCLUSION: EMACP combination chemotherapy is an effective treatment for high-risk GTN, with a remission rate comparable to EMA/CO. However, the difference in duration of treatment is only slightly shorter with EMACP. Cisplatin-based chemotherapy in the form of EMACP in this study was not proven more effective than EMA/CO.

Addition of rituximab to fludarabine and cyclophosphamide in patients with chronic lymphocytic leukaemia: a randomised, open-label, phase 3 trial.

BACKGROUND: On the basis of promising results that were reported in several phase 2 trials, we investigated whether the addition of the monoclonal antibody rituximab to first-line chemotherapy with fludarabine and cyclophosphamide would improve the outcome of patients with chronic lymphocytic leukaemia. METHODS: Treatment-naive, physically fit patients (aged 30-81 years) with CD20-positive chronic lymphocytic leukaemia were randomly assigned in a one-to-one ratio to receive six courses of intravenous fludarabine (25 mg/m(2) per day) and cyclophosphamide (250 mg/m(2) per day) for the first 3 days of each 28-day treatment course with or without rituximab (375 mg/m(2) on day 0 of first course, and 500 mg/m(2) on day 1 of second to sixth courses) in 190 centres in 11 countries. Investigators and patients were not masked to the computer-generated treatment assignment. The primary endpoint was progression-free survival (PFS). Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00281918. FINDINGS: 408 patients were assigned to fludarabine, cyclophosphamide, and rituximab (chemoimmunotherapy group) and 409 to fludarabine and cyclophosphamide (chemotherapy group); all patients were analysed. At 3 years after randomisation, 65% of patients in the chemoimmunotherapy group were free of progression compared with 45% in the chemotherapy group (hazard ratio 0·56 [95% CI 0·46-0·69], p<0·0001); 87% were alive versus 83%, respectively (0·67 [0·48-0·92]; p=0·01). Chemoimmunotherapy was more frequently associated with grade 3 and 4 neutropenia (136 [34%] of 404 vs 83 [21%] of 396; p<0·0001) and leucocytopenia (97 [24%] vs 48 [12%]; p<0·0001). Other side-effects, including severe infections, were not increased. There were eight (2%) treatment-related deaths in the chemoimmunotherapy group compared with ten (3%) in the chemotherapy group. INTERPRETATION: Chemoimmunotherapy with fludarabine, cyclophosphamide, and rituximab improves progression-free survival and overall survival in patients with chronic lymphocytic leukaemia. Moreover, the results suggest that the choice of a specific first-line treatment changes the natural course of chronic lymphocytic leukaemia. FUNDING: F Hoffmann-La Roche.

Phase II randomized study of trabectedin given as two different every 3 weeks dose schedules (1.5 mg/m2 24 h or 1.3 mg/m2 3 h) to patients with relapsed, platinum-sensitive, advanced ovarian cancer.

BACKGROUND: This randomized, open-label, phase II clinical trial evaluated the optimal regimen of trabectedin administered every 3 weeks in patients with platinum-sensitive, relapsed, advanced ovarian cancer (AOC). PATIENTS AND METHODS: Patients previously treated with less than two or two previous chemotherapy lines were randomized to receive trabectedin 1.5 mg/m(2) 24 h (arm A, n = 54) or 1.3 mg/m(2) 3 h (arm B, n = 53). Objective response rate (ORR) per RECIST was the primary efficacy end point. Toxic effects were graded according to the National Cancer Institute-Common Toxicity Criteria v. 2.0. RESULTS: ORR was 38.9% [95% confidence interval (CI) 25.9% to 53.1%; arm A] and 35.8% (95% CI 23.1% to 50.2%; arm B) (intention-to-treat primary analysis). Median time to progression was 6.2 months (95% CI 5.3-8.6 months; arm A) and 6.8 months (95% CI 4.6-7.4 months; arm B). Frequent severe adverse events were nausea/vomiting (24%, arm A; 15%, arm B) and fatigue (15%, arm A; 10%, arm B). Common severe laboratory abnormalities were transient, noncumulative neutropenia (55%, arm A; 37%, arm B) and transaminase increases (alanine aminotransferase, 55%, arm A; 59%, arm B). CONCLUSIONS: Both every-3-weeks trabectedin regimes, 1.5 mg/m(2) 24 h and 1.3 mg/m(2) 3 h, were active and reasonably well tolerated in AOC platinum-sensitive patients. Trabectedin every-3-weeks has promising activity and deserves to be further evaluated in relapsed AOC.

Embolization for hemorrhage of liver metastases from choriocarcinoma.

BACKGROUND: Because gestational trophoblastic disease (GTD) is highly sensitive to chemotherapy, life-threatening hemorrhage from metastases can occur especially early after starting therapy. CASES: Two cases of post-term choriocarcinoma with liver metastases complicated by profuse life-threatening hemorrhage are reported. Emergency treatment with transcatheter angiographic embolization of the hepatic artery was performed to control bleeding. DISCUSSION: Although embolization of the iliac vessels for gynecologic malignancies, including GTD, have been described, this is the first time that embolization of the hepatic artery to control bleeding from liver metastases in GTD is reported. The use and indications for embolization are expanding, and also in acute hemorrhagic complications in GTD, this intervention should be considered.

Phase II study of carboplatin and whole body hyperthermia (WBH) in recurrent and metastatic cervical cancer.

OBJECTIVE: Hyperthermia enhances carboplatin cytotoxicity preclinically, and clinical studies have shown radiant heat Whole Body Hyperthermia (WBH) to be safe. In this study, the efficacy and toxicity of the combination of 41.8 degrees C WBH and carboplatin in recurrent and/or metastatic cervical cancer were explored. METHODS: Recurrent and/or metastatic cervical cancer patients were treated with 41.8 degrees C WBH and concurrent carboplatin, cycled every 28 days (max. 6 cycles). RESULTS: Twenty-one of 25 participants were evaluable for response: one complete remission, six partial responses, stable disease in nine patients and progression in five, leading to a response rate of 33%. Three of four evaluable chemotherapy pre-treated patients progressed, while this was seen in only 2 of 17 chemotherapy-naive patients. The median survival is 7.8 months (range 1.3 to 43+) and no patients were lost to follow up. Grades 3/4 toxicities were common: leukopenia in 35%, thrombopenia in 61% and anemia in 22% of all treatments. Excessive, partly reversible renal toxicity was seen in two patients (grades 3 and 4). CONCLUSION: The efficacy of WBH and carboplatin in recurrent and/or metastatic cervical cancer seems comparable to that of other palliative chemotherapy regimens in this disease. The considerable toxicity, though largely manageable, includes unexpected and severe unacceptable renal toxicity. This regimen seems less suitable for palliative care.

[Severe toxicity after treatment with capecitabine and fluorouracil due to partial dihydropyrimidine dehydrogenase deficiency]. / Ernstige toxiciteit na behandeling met capecitabine en fluorouracil ten gevolge van een partiële dihydropyrimidine-dehydrogenasedeficiëntie.

Two female patients, aged 48 and 52 years, developed severe bone marrow suppression and (gastrointestinal) mucositis following administration of capecitabine. Analysis of the dihydropyrimidine dehydrogenase (DPD) activity in peripheral blood mononuclear cells revealed the presence of DPD deficiency. Both patients recovered in 3-4 weeks, and both had a (partial) remission of their tumours. Capecitabine is metabolised to 5-fluorouracil (5-FU) in the body. DPD-deficiency leads to impaired breakdown of 5-FU and hence to severe cytotoxicity following treatment with capecitabine or 5-FU. The most common mutation, IVS14 + 1G > A, is found in approximately 2% of the Dutch population. In case of unexpected severe toxicity during 5-FU or capecitabine treatment, DPD deficiency should be considered. Screening could be considered in view of the widespread use of capecitabine and 5-FU, the severe toxicity that may develop in patients with low DPD activity and the prevalence of the mutation.
