Combining Melphalan Percutaneous Hepatic Perfusion with Ipilimumab Plus Nivolumab in Advanced Uveal Melanoma: First Safety and Efficacy Data from the Phase Ib Part of the Chopin Trial.

PURPOSE: To define a safe treatment dose of ipilimumab (IPI) and nivolumab (NIVO) when applied in combination with percutaneous hepatic perfusion with melphalan (M-PHP) in metastatic uveal melanoma (mUM) patients (NCT04283890), primary objective was defining a safe treatment dose of IPI/NIVO plus M-PHP. Toxicity was assessed according to Common Terminology Criteria for Adverse Events version 4.03 (CTCAEv4.03). Secondary objective was response rate, PFS and OS. MATERIALS AND METHODS: Patients between 18-75 years with confirmed measurable hepatic mUM according to RECIST 1.1 and WHO performance score 0-1 were included. Intravenous IPI was applied at 1 mg/kg while NIVO dose was increased from 1 mg/kg in cohort 1 to 3 mg/kg in cohort 2. Transarterial melphalan dose for M-PHP was 3 mg/kg (maximum of 220 mg) in both cohorts. Treatment duration was 12 weeks, consisting of four 3-weekly courses IPI/NIVO and two 6-weekly M-PHPs. RESULTS: Seven patients were included with a median age of 63.6 years (range 50-74). Both dose levels were well tolerated without dose-limiting toxicities or deaths. Grade III/IV adverse events (AE) were observed in 2/3 patients in cohort 1 and in 3/4 patients in cohort 2, including Systemic Inflammatory Response Syndrome (SIRS), febrile neutropenia and cholecystitis. Grade I/II immune-related AEs occurred in all patients, including myositis, hypothyroidism, hepatitis and dermatitis. There were no dose-limiting toxicities. The safe IPI/NIVO dose was defined as IPI 1 mg/kg and NIVO 3 mg/kg. There was 1 complete response, 5 partial responses and 1 stable disease (3 ongoing responses with a median FU of 29.1 months). CONCLUSION: Combining M-PHP with IPI/NIVO was safe in this small cohort of patients with mUM at a dose of IPI 1 mg/kg and NIVO 3 mg/kg.

Combining Hepatic Percutaneous Perfusion with Ipilimumab plus Nivolumab in advanced uveal melanoma (CHOPIN): study protocol for a phase Ib/randomized phase II trial.

BACKGROUND: While immune checkpoint inhibition (ICI) has revolutionized the treatment of metastatic cutaneous melanoma, no standard treatments are available for patients with metastatic uveal melanoma (UM). Several locoregional therapies are effective in the treatment of liver metastases, such as percutaneous hepatic perfusion with melphalan (M-PHP). The available literature suggests that treatment with ICI following locoregional treatment of liver UM metastases can result in clinical response. We hypothesize that combining M-PHP with ICI will lead to enhanced antigen presentation and increased immunomodulatory effect, improving control of both hepatic and extrahepatic disease. METHODS: Open-label, single-center, phase Ib/randomized phase II trial, evaluating the safety and efficacy of the combination of M-PHP with ipilimumab (anti-CTLA-4 antibody) and nivolumab (anti-PD-1 antibody) in patients with unresectable hepatic metastases of UM in first-line treatment, with or without the limited extrahepatic disease. The primary objective is to determine the safety, toxicity, and efficacy of the combination regimen, defined by maximum tolerated dose (MTD) and progression-free survival (PFS) at 1 year. Secondary objectives include overall survival (OS) and overall response rate (ORR). A maximum of 88 patients will be treated in phase I and phase II combined. Baseline characteristics will be described with descriptive statistics (t-test, chi-square test). To study the association between risk factors and toxicity, a logistic regression model will be applied. PFS and OS will be summarized using Kaplan-Meier curves. DISCUSSION: This is the first trial to evaluate this treatment combination by establishing the maximum tolerated dose and evaluating the efficacy of the combination treatment. M-PHP has shown to be a safe and effective treatment for UM patients with liver metastases and became the standard treatment option in our center. The combination of ICI with M-PHP is investigated in the currently described trial which might lead to a better treatment response both in and outside the liver. TRIAL REGISTRATION: This trial was registered in the US National Library of Medicine with identifier NCT04283890 . Registered as per February 2020 - Retrospectively registered. EudraCT registration number: 2018-004248-49. Local MREC registration number: NL60508.058.19.

Relation between body composition and severe diarrhea in patients treated with preoperative chemoradiation with capecitabine for rectal cancer: a single-centre cohort study.

BACKGROUND: Chemoradiation with capecitabine followed by surgery is standard care for locally advanced rectal cancer (LARC). Severe diarrhea is considered a dose-limiting toxicity of adding capecitabine to radiation therapy. The aim of this study was to describe the risk factors and the impact of body composition on severe diarrhea in patients with LARC during preoperative chemoradiation with capecitabine. METHODS: A single centre retrospective cohort study was conducted in a tertiary referral centre. All patients treated with preoperative chemoradiation with capecitabine for LARC from 2009 to 2015 were included. Patients with locally recurrent rectal cancer who received chemoradiation for the first time were included as well. Logistic regression analyses were performed to identify risk factors for severe diarrhea. RESULTS: A total of 746 patients were included. Median age was 64 years (interquartile range 57-71) and 477 patients (64%) were male. All patients received a radiation dosage of 25 × 2 Gy during a period of five weeks with either concomitant capecitabine administered on radiation days or continuously during radiotherapy. In this cohort 70 patients (9%) developed severe diarrhea. In multivariable logistic regression analyses female sex (OR: 4.42, 95% CI 2.54-7.91) and age ≥ 65 (OR: 3.25, 95% CI 1.85-5.87) were the only risk factors for severe diarrhea. CONCLUSIONS: Female patients and patients aged sixty-five or older had an increased risk of developing severe diarrhea during preoperative chemoradiation therapy with capecitabine. No relation was found between body composition and severe diarrhea.

The clinical relevance of indeterminate lung nodules in patients with locally recurrent rectal cancer.

AIM: To evaluate the clinical relevance of indeterminate lung nodules (ILN) in patients with locally recurrent rectal cancer (LRRC) treated in a tertiary referral centre. METHODS: All patients with LRRC diagnosed between 2000 and 2017 were retrospectively reviewed. Reports of staging chest CT-scans were evaluated for ILN. Patients with distant metastases including lung metastases at time of LRRC diagnosis were excluded. Overall (OS), progression-free survival (PFS) and the cumulative incidence of lung metastases were compared between patients with and without ILN. RESULTS: In total 556 patients with LRRC were treated during the study period. In the 243 patients eligible for analysis, 68 (28%) had ILN at LRRC diagnosis. Median OS was 37 months for both the patients with and without ILN (p = 0.37). Median PFS was 14 months for the patients with ILN and 16 months for patients without ILN (p = 0.80). After correction for potential confounding, ILN present at LRRC diagnosis was not associated with impaired OS or PFS (adjusted hazards ratio [95% confidence interval]: 0.81 [0.54-1.22] and 1.09 [0.75-1.59]). The 5-year cumulative incidence of lung metastases was 31% in patients with ILN and 28% in patients without ILN (p = 0.19). CONCLUSION: Our study shows that ILN are present in roughly a quarter of patients with LRRC. No differences in OS, PFS, or the cumulative incidence of lung metastases were found between patients with and without ILN at LRRC diagnosis. These results suggest that ILN are of little to no clinical relevance in patients with LRRC.

Locally recurrent rectal cancer; long-term outcome of curative surgical and non-surgical treatment of 447 consecutive patients in a tertiary referral centre.

INTRODUCTION: The majority of patients with locally recurrent rectal cancer (LRRC) present with extensive metastatic disease or an unresectable recurrence, and will be treated palliatively. Only a minority of patients will be eligible for potential cure by surgical treatment. The aim of this study is to evaluate the long-term outcome of surgical treatment and non-surgical treatment of patients with LRRC. METHODS: All patients with LRRC referred to our tertiary institute between 2000 and 2015 were retrospectively analysed. Patients were discussed in a multidisciplinary tumour board (MDT) and eventually received curative surgical or non-surgical treatment. Overall survival (OS) was compared by resection margin status and non-surgical treatment. RESULTS: A total of 447 patients were discussed in our MDT of which 193 patients underwent surgical treatment and 254 patients received non-surgical treatment. Surgically treated patients were significantly younger, received less neoadjuvant therapy for the primary tumour, had less metastasis at diagnosis and more central recurrences. The 5-year OS was 51% for R0-resections and 34% for R1-resections. Although numbers with R2-resections were too small to implicate prognostic significance, there was no difference in 5-year OS between R2-resections and non-surgical treatment (10% vs. 4%, p = 0.282). In a subgroup analysis the OS of R2-patients was even poorer compared to optimal palliative treated patients with combined chemotherapy and radiotherapy (22 vs 29 months, p = 0.413). CONCLUSION: R2-resections do not result in a survival benefit compared to non-surgical treatment in this non-randomized series. Patients with a high chance on a R2-resection could be offered non-surgical treatment, without local resection.

Treatment of Inguinal Lymph Node Metastases in Patients with Rectal Adenocarcinoma.

BACKGROUND: Inguinal lymph node metastases (ILNM) from rectal adenocarcinoma are rare and staged as systemic disease. This study aimed to provide insight into the treatment and prognosis of ILNM from rectal adenocarcinoma. METHODS: All patients with a diagnosis of synchronous or metachronous ILNM from rectal adenocarcinoma between January 2005 and March 2017 were retrospectively reviewed. RESULTS: The study identified 27 patients with ILNM (15 with synchronous and 12 with metachronous disease). After discussion by a multidisciplinary tumor board, 19 patients were treated with curative intent, 17 of whom underwent inguinal lymph node dissection. Of the 17 patients, 12 had locally advanced rectal cancer (LARC) with isolated ILNM, 3 had LARC and metastases elsewhere, and 2 had locally recurrent rectal cancer (LRRC). The median overall survival (OS) for all the patients treated with curative intent was 27 months [95% confidence interval (CI) 11.6-42.4 months], with a 5-year OS rate of 34%. The median OS for the patients with LARC and isolated ILNM (n = 12) was 74 months (95% CI 18.0-130.0 months), with a 5-year OS rate of 52%. All the patients with metastases elsewhere (n = 3) or LRRC (n = 2) experienced recurrent systemic disease. Eight patients were treated with palliative intent. The median OS for this group was 13 months (95% CI 1.9-24.1 months), with a 3-year OS rate of 0%. CONCLUSION: Clinicians should not consider ILNM as an incurable systemic disease. Patients with primary rectal cancer and solitary ILNM who were eligible for curative surgical treatment had a 5-year survival rate of 52%. The prognosis for patients with additional systemic metastases or LRRC is worse, and the benefit of surgery is unclear.

The liver-first approach for locally advanced rectal cancer and synchronous liver metastases.

BACKGROUND: Patients with locally advanced rectal cancer (LARC) and synchronous liver metastases (sRLM) can be treated according to the liver-first approach. This study aimed to evaluate prognostic factors for completing treatment and in how many patients extensive lower pelvic surgery might have been omitted. METHODS: Retrospective analysis of all patients with LARC and sRLM treated at the Erasmus MC Cancer Institute according to the liver-first between 2003 and 2016. RESULTS: In total 129 consecutive patients were included. In 90 patients (70%) the liver-first was completed. Ten patients had a (near) complete response (ypT0-1N0) of their primary tumour. In 36 out of 39 patients not completing the liver-first protocol palliative rectum resection was withheld. Optimal cut-offs for CEA level (53.15 µg/L), size (3.85 cm) and number (4) of RLMs were identified. A preoperative CEA level above 53.15 µg/L was an independent predictor for non-completion of the liver-first protocol (p = 0.005). CONCLUSION: Ten patients had a (near) complete response of their primary tumour and, in retrospect, rectum sparing therapies could have been considered. Together with 36 patient in whom palliative rectum resection was not necessary this entails that nearly 40% patients with LARC and sRLM might be spared major pelvic surgery if the liver-first approach is applied. A predictor (CEA) was found for non-completion of the liver-first protocol. The majority of patients underwent resection of both primary tumour and hepatic metastasis with curative intent. These findings together entail that the liver-first approach may be considered in patients with LARC and sRLM.

Total pelvic exenteration for locally advanced and locally recurrent rectal cancer in the elderly.

BACKGROUND: Total pelvic exenteration (TPE) is a radical approach for locally advanced rectal cancer (LARC) and locally recurrent rectal cancer (LRRC) in case of tumour invasion into the urogenitary tract. The aim of this study is to assess surgical and oncological outcomes of TPE for LARC and LRRC in elderly patients compared to younger patients. METHODS: All patients who underwent TPE for LARC and LRRC between January 1990 and March 2017 were retrospectively analyzed. Patients aged <70 years were classified as younger and ≥70 years as elderly patients. RESULTS: In total 126 patients underwent TPE, of whom 88 younger and 38 elderly patients. Elderly patients had a significantly higher number of ASA > II patients (p = 0.01). Indication for surgery LARC (n = 73) and LRRC (n = 53) did not differ significantly. The 30-day mortality rate was significantly higher (p = 0.01) in elderly (13%) compared to younger patients (3%). Elderly patients experienced more anastomotic leakage (p = 0.02). Median overall survival (OS) was 75 months [95%CI 37.1; 112.9] for elderly and 45 months [95%CI 22.4; 67.8] for younger patients (p = 0.77). The 5-year OS rate was 44% in both groups. Median disease specific survival (DSS) was 78 months [95%CI 69.1; 86.9] for elderly and 60 months [95%CI 36.6; 83.4] for younger patients (p = 0.34). The 5-year DSS rate was 57% and 49%, respectively. CONCLUSION: TPE is an invasive treatment for rectal cancer with high 30-day mortality in elderly patients. Oncological outcomes are similar in elderly and younger patients. Therefore, TPE should not be withheld because of high age only, but careful patient selection is needed.

Feasibility and effectiveness of trifluridine/tipiracil in metastatic colorectal cancer: real-life data from The Netherlands.

BACKGROUND: The RECOURSE trial showed clinical efficacy for trifluridine/tipiracil for refractory metastatic colorectal cancer patients. We assessed the feasibility and effectiveness of trifluridine/tipiracil in daily clinical practice in The Netherlands. METHODS: Medical records of patients from 17 centers treated in the trifluridine/tipiracil compassionate use program were reviewed and checked for RECOURSE eligibility criteria. Baseline characteristics, safety, and survival times were compared, and prespecified baseline characteristics were tested in multivariate analyses for prognostic significance on overall survival (OS). RESULTS: A total of 136 patients with a median age of 62 years were analyzed. Forty-three patients (32%) did not meet the RECOURSE eligibility criteria for not having received all prior standard treatments (n = 35, 26%) and/or ECOG performance status (PS) 2 (n = 12, 9%). The most common grade ≥3 toxicities were neutropenia (n = 44, 32%), leukopenia (n = 8, 6%), anemia (n = 7, 5%), and fatigue (n = 7, 5%). Median progression-free survival (PFS) and median OS were 2.1 (95% CI, 1.8-2.3) and 5.4 months (95% CI, 4.0-6.9), respectively. Patients with ECOG PS 2 had a worse median OS (3.2 months) compared to patients with ECOG PS 0-1 (5.9 months). ECOG PS, KRAS-mutation status, white blood cell count, serum lactate dehydrogenase, and alkaline phosphatase were prognostic factors for OS. CONCLUSIONS: Our data show that treatment with trifluridine/tipiracil in daily clinical practice is feasible and safe. Differences in patient characteristics between our population and the RECOURSE study population should be taken into account in the interpretation of survival data. Our results argue against the use of trifluridine/tipiracil in patients with ECOG PS 2. FUNDING: Johannes J.M. Kwakman received an unrestricted research grant from Servier.

Response to chemotherapy in patients with recurrent rectal cancer in previously irradiated area.

BACKGROUND: Tumor lesions in previously irradiated area may have a less favorable response to chemotherapy compared to tumor sites outside the radiation field. The aim of the present study was to evaluate the response to chemotherapy of locally recurrent rectal cancer (LRRC) within the previous radiation field compared to the response of distant metastases outside the radiation field. PATIENTS AND METHODS: All patients with LRRC referred between 2000 and 2012 to our tertiary university hospital were reviewed. The response to chemotherapy of LRRC within previously irradiated area was compared to the response of synchronous distant metastases outside the radiation field according to the Response Evaluation Criteria in Solid Tumors (RECIST). RESULTS: Out of 363 cases with LRRC, 29 previously irradiated patients with distant metastases were treated with chemotherapy and eligible for analysis. Twenty-six patients (89 %) suffered a first recurrence and three patients (11 %) a second recurrence. These patients were followed with a median of 22 months (IQR, 9-40 months) and had a median survival of 33 months (IQR, 14-42). In 23 patients (79 %), the local recurrence showed stable disease, but the overall response rate of the local recurrences in the previously irradiated area was significantly lower than the response rate of distant metastases outside the radiation field (10 vs. 41 %,p = 0.034). CONCLUSIONS: Previously irradiated patients with LRRC have a lower response rate to chemotherapy of the local recurrence within the radiation field compared to the response rate of distant metastases outside the radiation field. This suggests that chemotherapy for local palliation may not have the desired effect.

The use of neo-adjuvant chemotherapy in patients with resectable colorectal liver metastases: Clinical risk score as possible discriminator.

AIM: The combination of surgery and chemotherapy (CTx) is increasingly accepted as an effective treatment for patients with colorectal liver metastases (CRLM). However, controversy exists whether all patients with resectable CRLM benefit from perioperative CTx. We investigated the impact on overall survival (OS) by neo-adjuvant CTx in patients with resectable CRLM, stratified by the clinical risk score (CRS) described by Fong et al. METHODS: Patients who underwent surgery for CRLM between January 2000 and December 2009 were included. We compared OS of patients with and without neo-adjuvant CTx stratified by the CRS. The CRS includes five prognosticators and defines two risk groups: low CRS (0-2) and high CRS (3-5). RESULTS: 363 patients (64% male) were included, median age 63 years (IQR 57-70). Prior to resection, 219 patients had a low CRS (neo-adjuvant CTx: N = 65) and 144 patients had a high CRS (neo-adjuvant CTx: N = 88). Median follow-up was 47 months (IQR 25-82). In the low CRS group, there was no significant difference in median OS between patients with and without CTx (65 months (95% CI 39-91) vs. 54 months (95% CI 44-64), P = 0.31). In the high CRS group, there was a significant difference in OS between patients with and without CTx (46 months (95% CI 24-68) vs. 33 month (95% CI 29-37), P = 0.004). CONCLUSION: In our series, patients with a high CRS benefit from neo-adjuvant CTx. In patients with a low risk profile, neo-adjuvant CTx might not be beneficial.

Chemoradiation therapy for rectal cancer in the distal rectum followed by organ-sparing transanal endoscopic microsurgery (CARTS study).

BACKGROUND: This prospective multicentre study was performed to quantify the number of patients with minimal residual disease (ypT0-1) after neoadjuvant chemoradiotherapy and transanal endoscopic microsurgery (TEM) for rectal cancer. METHODS: Patients with clinically staged T1-3 N0 distal rectal cancer were treated with long-course chemoradiotherapy. Clinical response was evaluated 6-8 weeks later and TEM performed. Total mesorectal excision was advocated in patients with residual disease (ypT2 or more). RESULTS: The clinical stage was cT1 N0 in ten patients, cT2 N0 in 29 and cT3 N0 in 16 patients. Chemoradiotherapy-related complications of at least grade 3 occurred in 23 of 55 patients, with two deaths from toxicity, and two patients did not have TEM or major surgery. Among 47 patients who had TEM, ypT0-1 disease was found in 30, ypT0 N1 in one, ypT2 in 15 and ypT3 in one. Local recurrence developed in three of the nine patients with ypT2 tumours who declined further surgery. Postoperative complications grade I-IIIb occurred in 13 of 47 patients after TEM and in five of 12 after (completion) surgery. After a median follow-up of 17 months, four local recurrences had developed overall, three in patients with ypT2 and one with ypT1 disease. CONCLUSION: TEM after chemoradiotherapy enabled organ preservation in one-half of the patients with rectal cancer.

Management of isolated nonresectable liver metastases in colorectal cancer patients: a case-control study of isolated hepatic perfusion with melphalan versus systemic chemotherapy.

BACKGROUND: To compare the median overall survival of patients with isolated nonresectable liver metastases in comparable groups of patients treated with either isolated hepatic perfusion (IHP) with melphalan or systemic chemotherapy. PATIENTS AND METHODS: Colorectal cancer patients with isolated liver metastases, who underwent IHP, were included in this study. The control group consisted of a subgroup of colorectal cancer patients with liver metastases only, who were enrolled in the randomized CApecitabine, IRinotecan, Oxaliplatin (CAIRO) phase III study. RESULTS: Ninety-nine patients were treated with IHP, and 111 patients were included in the control group. All patient characteristics were comparable except for age. Median follow-up was 78.1 months for IHP versus 54.7 months in the control group. Median overall survival was 25.0 [95% confidence interval (CI) 19.4-30.6] months for IHP and 21.7 (95% CI 19.6-23.8) months for systemic treatment and did not differ significantly (P = 0.29). Treatment-related mortality was 2% for the systemic treatment and 6% for IHP (P = 0.11). CONCLUSION: Compared with a patient group with comparable characteristics treated with systemic chemotherapy, IHP does not provide a benefit in overall survival in patients with isolated nonresectable colorectal liver metastases. Currently, the use of IHP cannot be advocated outside the scope of clinical studies.

Pathological analysis after neoadjuvant chemoradiotherapy for esophageal carcinoma: the Rotterdam experience.

Multimodality treatment is increasingly used in the treatment for esophageal cancer. We determined the tumor regression grade after preoperative chemoradiation and correlated the effect of specific pathologic and clinical findings to overall survival. For this purpose esophageal biopsies and surgical specimens of 67 patients treated with neoadjuvant paclitaxel and carboplatin concurrent with radiotherapy were reviewed. Neoadjuvant chemoradiotherapy led to a significant downstaging. Complete tumor regression was found in 24% of the patients resulting in a trend towards better survival. It was found more frequently in poorly differentiated tumors. Patients with pre-treatment nodal involvement, assessed by endoscopic ultrasound, had a significantly worse survival compared to patients without. Contrastingly, this was not found for post-treatment nodal involvement, as determined by pathological examination, speculating that survival is more determined by (submicroscopic) distant disease, than by locoregional tumor cells.

[Chemotherapy during clozapine treatment. Increased risk of agranulocytosis?]. / Chemotherapie bij gebruik van clozapine; een verhoogde kans op agranulocytose?

In a 37-year-old female, a combined treatment consisting of chemotherapy and radiation was considered for cervical cancer. However, she was using clozapine for the treatment of schizophrenia. As both clozapine and chemotherapy can induce decrease of white blood cell counts, we had to decide if clozapine and chemotherapy could be safely co-prescribed. Hypotheses concerning the mechanisms underlying clozapine-induced decrease of white blood cell counts and case reports on combining chemotherapy and clozapine are discussed. After cessation of clozapine the psychosis recurred despite treatment with risperidone. The decision was made to administer radiotherapy only and to reinstate the treatment with clozapine. The radiotherapy treatment went according to plan and the psychosis receded.

Isolated hepatic melphalan perfusion of colorectal liver metastases: outcome and prognostic factors in 154 patients.

BACKGROUND: The aim of this study was to identify prognostic factors for local and systemic failure after isolated hepatic perfusion (IHP) with 200 mg melphalan in patients with colorectal liver metastases. PATIENTS AND METHODS: Hundred and fifty-four patients were selected for IHP and underwent laparotomy. Patients were monitored for response, toxicity and survival. Univariate and multivariate analyses were carried out to identify prognostic factors for hepatic response and progression-free and overall survival. RESULTS: Hepatic response rate was 50% with a median progression-free and overall survival of, respectively, 7.4 and 24.8 months. In multivariate analyses, absence of ability to perfuse through the hepatic artery (P = 0.003), severe postoperative complications (P = 0.048) and >10 liver metastases (P = 0.006) adversely influenced overall survival and no adjuvant chemotherapy adversely influenced progression-free survival. CONCLUSION: This is the first study to report prognostic factors for survival after IHP. Possibly, overall and disease-free survival can increase if preoperative screening is improved. In future studies on IHP, adjuvant chemotherapy should be considered.

First-line treatment with oxaliplatin and capecitabine in patients with advanced or metastatic oesophageal cancer: a phase II study.

This phase II study assessed the safety and efficacy of oxaliplatin and capecitabine in patients with advanced oesophageal cancer. Fifty-one eligible patients received oxaliplatin 130 mg m(-2) intravenously on day 1 and capecitabine 1000 mg m(-2) orally twice daily on days 1 to 14 in a 21-day treatment cycle as first-line treatment for advanced oesophageal cancer. Grade 3 neutropenia was seen in one patient and anaemia in another patient. No grade 4 haematological toxicities were observed. Grade 4 non-haematological toxicity (lethargy) occurred in one patient (2%). Grade 3 non-haematological toxicity was seen in 14 (27%) patients (vomiting and polyneuropathy (8%); nausea (6%); lethargy and hand-foot syndrome (4%); and anorexia, diarrhoea, and hyperbilirubinaemia (each in one patient)). In 22% of the patients, toxicity was the reason for stopping the treatment. The overall response rate was 39%. The median overall survival was 8 months; the 1-year survival rate was 26%. In the quality of life (QoL) analysis, the emotional well-being improved during treatment, but the physical functioning scores declined. The fatigue score on the symptom scales increased. Overall, the global QoL score did not change during treatment. In conclusion, the activity of oxaliplatin and capecitabine is comparable with other chemotherapy regimens in advanced oesophageal cancer with a low frequency of grade 3/4 toxicity. Because this treatment can be given on an outpatient basis, it is probably less toxic than cisplatin-based therapy and preserves QoL during treatment, it is a viable treatment option in patients with advanced oesophageal cancer.

Hepatic artery infusion of high-dose melphalan at reduced flow during isolated hepatic perfusion for the treatment of colorectal metastases confined to the liver: a clinical and pharmacologic evaluation.

Isolated hepatic perfusion (IHP) offers the advantage of high local drug exposure with limited systemic toxicity. To increase local drug exposure, we administered melphalan at a reduced flow in the hepatic artery during IHP (hepatic artery infusion, hepatic artery-portal vein perfusion, HI-HPP). Between December 2001 and December 2004, 30 patients with colorectal cancer liver metastases underwent HI-HPP with 200mg melphalan. Samples of the perfusate were taken for pharmacokinetic analysis. Patients were monitored for response, toxicity and survival. Perfusion was aborted prematurely in 2 patients due to leakage. During melphalan administration in the hepatic inflow cannula a mean flow rate of 121.3 mL/min and mean pressure of 62.5mm Hg were achieved. One patient died within 30 days after HI-HPP. Four patients developed veno-occlusive disease (VOD), while 2 patients showed signs of VOD. Twelve patients showed hepatic response, with a median duration of response of 11.5 months, according to WHO criteria. Although HI-HPP results in high perfusate melphalan concentration levels, it is associated with a relatively high level of hepatotoxicity and a limited response rate. We believe that the low flow and pressure rates found in this study can result in reduced drug penetration of the tumour and thus limited tumour response.

Neoadjuvant concurrent chemoradiation with weekly paclitaxel and carboplatin for patients with oesophageal cancer: a phase II study.

This study was performed to assess the efficacy and safety of preoperative chemoradiation consisting of carboplatin and paclitaxel and concurrent radiotherapy for patients with resectable (T2-3N0-1M0) oesophageal cancer. Treatment consisted of paclitaxel 50 mg m(-2) and carboplatin AUC=2 on days 1, 8, 15, 22 and 29 and concurrent radiotherapy (41.4 Gy in 23 fractions, 5 days per week), followed by oesophagectomy. All 54 entered patients completed the chemoradiation without delay or dose-reduction. Grade 3-4 toxicities were: neutropaenia 15%, thrombocytopaenia 2%, and oesophagitis 7.5%. After completion of the chemoradiotherapy 63% had a major endoscopical response. Fifty-two patients (96%) underwent a resection. The postoperative mortality rate was 7.7%. All patients had an R0-resection. The pathological complete response rate was 25%, and an additional 36.5% had less than 10% vital residual tumour cells. At a median follow-up of 23.2 months, the median survival time has not yet been reached. The probability of disease-free survival after 30 months was 60%. In conclusion, weekly neoadjuvant paclitaxel and carboplatin with concurrent radiotherapy is a very tolerable regimen and can be given on an outpatient basis. It achieves considerable down staging and a subsequent 100% radical resection rate in this series. A phase III trial with this regimen is now ongoing.

[Clinical thinking and decision making in practice. A young woman with fever, arthralgia and exanthema]. / Klinisch denken en beslissen in de praktijk. Een jonge vrouw met koorts, artralgie en exantheem.

A 19-year-old woman was admitted because of high fever, rash, arthralgia and sore throat. On physical examination a diffuse skin rash was observed, leaving a facial mask unaffected. C-reactive protein and erythrocyte sedimentation rate were raised (114 mg/l and 26 mm in the first hour, respectively); white blood cell count was normal (6.2 x 10(9)/l) with an increased count of immature forms. An infective, metabolic or haematological cause was excluded. Serum ferritin turned out to be extremely elevated (4318 micrograms/l), so adult-onset Still's disease was diagnosed. The patient fulfilled the criteria of Cush et al. for adult-onset Still's disease. She was first treated with non-steroidal anti-inflammatory drugs (NSAIDs) and, at a later stage in the disease, with corticosteroids. All symptoms disappeared and blood test results normalised.
