Chemotherapy and Chemoradiotherapy Studies in Oesophageal Cancer
The aim of this thesis was, first, to explore the
use of preoperative chemoradiotherapy and palliative chemotherapy in
the treatment of oesophageal cancer. Furthermore, the effects of a
chemoradiotherapy regimen on histopathological and psychological and
social level were studied.
Chapter 2 provides a review of the literature on systemic treatment
for oesophageal cancer. An overview is given for preoperative and
postoperative chemotherapy, preoperative chemoradiotherapy, definitive
chemoradiotherapy, and palliative chemotherapy.
In Chapter 3 the efficacy and safety of preoperative chemoradiotherapy
consisting of carboplatin and paclitaxel and concurrent radiotherapy
for patients with resectable oesophageal cancer is studied.
Chapter 4 describes the histopathological effects of the above
mentioned chemoradiotherapy regimen and correlates the effect of
specific pathologic and clinical findings to overall survival.
In Chapter 5 the health related quality of life up to one year after
surgery, in patients with oesophageal cancer treated with curative
intent with neoadjuvant chemoradiotherapy consisting of the above
mentioned regimen followed by oesophagectomy is evaluated.
Finally, in Chapter 6 the analysis of a phase II study evaluating the
safety and efficacy of the combination of oxaliplatin and capecitabine
in patients with metastatic or local-regional unresectable carcinoma
of the oesophagus, oesophagogastric junction, and cardia is given. In
addition, the effect of this regimen of the patients’ well-being is
evaluated by performing a quality of life analysis on these patients
during the treatment.
The studies described in this thesis are summarized in Chapter 7.
Furthermore, potential directions for future studies are addressed
The views of cancer patients of Turkish, Moroccan, Surinamese, and Dutch-Caribbean descent on diagnosis, treatment and prognosis:A systematic literature review
Background: The number of international migrants is increasing worldwide. The four major non-western ethnic groups in the Netherlands are Turkish, Moroccan, Surinamese, and Dutch-Caribbean. This review examined the scientific literature on the views of cancer patients from these four ethnic groups on cancer diagnosis, treatment, and prognosis. Methods: A systematic literature review was conducted using the databases EMBASE, Medline Web of Science, and Cochrane Central Register. Studies with patients who were of Turkish, Moroccan, Surinamese, and Dutch-Caribbean descent were included. Both qualitative and quantitative studies were included, and thematic analysis was performed. The methodological quality was assessed using the Mixed Methods Appraisal Tool. Results: Thirteen studies were conducted in Turkey on Turkish cancer patients, while three were conducted in the Netherlands on Turkish and Moroccan cancer patients. Four themes emerged from the included studies: disclosure of diagnosis, communication, information provision, and decision-making. The majority of cancer patients in Turkey wanted information regarding their diagnosis and treatment. However, disclosure of a cancer diagnosis was rarely discussed with cancer patients in Turkey, whereas in the Netherlands it was provided directly. Family members in both the host and native countries had a strong influence on communication and decision-making. No literature on this topic for Surinamese or Dutch-Caribbean cancer patients was found. Conclusion: Although major ethnic groups live in host countries, there is a lack of knowledge on optimal communication and information disclosure on cancer to patients and their families. Policy summary: Further research into the views of ethnic groups on how to communicate about cancer is essential to ensuring that every patient receives optimal care and treatment.</p
Irinotecan-Induced Toxicity:A Pharmacogenetic Study Beyond UGT1A1
Background and objective: Side effects of irinotecan treatment can be dose limiting and may impair quality of life. In this study, we investigated the correlation between single nucleotide polymorphisms (SNPs) in genes encoding enzymes involved in the irinotecan metabolism and transport, outside UGT1A1, and irinotecan-related toxicity. We focused on carboxylesterases, which are involved in formation of the active metabolite SN-38 and on drug transporters. Methods: Patients who provided written informed consent at the Erasmus Medical Center Cancer Institute to the Code Geno study (local protocol: MEC02-1002) or the IRI28-study (NTR-6612) were enrolled in the study and were genotyped for 15 SNPs in the genes CES1, CES2, SLCO1B1, ABCB1, ABCC2, and ABCG2. Results: From 299 evaluable patients, 86 patients (28.8%) developed severe irinotecan-related toxicity. A significantly higher risk of toxicity was seen in ABCG2 c.421C>A variant allele carriers (P = 0.030, OR 1.88, 95% CI 1.06–3.34). Higher age was associated with all grade diarrhea (P = 0.041, OR 1.03, 95% CI 1.00–1.06). In addition, CES1 c.1165-41C>T and CES1 n.95346T>C variant allele carriers had a lower risk of all-grade thrombocytopenia (P = 0.024, OR 0.42, 95% CI 0.20–0.90 and P = 0.018, OR 0.23, 95% CI 0.08–0.79, respectively). Conclusion: Our study indicates that ABCG2 and CES1 SNPs might be used as predictive markers for irinotecan-induced toxicity.</p
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.
Result
Survival of patients with head and neck cancer with metachronous multiple primary tumors is surprisingly favorable
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
Concomitant intraperitoneal and systemic chemotherapy for extensive peritoneal metastases of colorectal origin: protocol of the multicentre, open-label, phase I, dose-escalation INTERACT trial
INTRODUCTION: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) has become standard of care for patients with peritoneal metastases of colorectal origin with a low/moderate abdominal disease load. In case of a peritoneal cancer index (PCI) score >20, CRS-HIPEC is not considered to be beneficial. Patients with a PCI >20 are currently offered palliative systemic chemotherapy. Previous studies have shown that systemic chemotherapy is less effective against peritoneal metastases than it is against haematogenous spread of colorectal cancer. It is suggested that patients with peritoneal metastases may benefit from the addition of intraperitoneal chemotherapy to systemic chemotherapy. Aim of this study is to establish the maximum tolerated dose of intraperitoneal irinotecan, added to standard of care systemic therapy for colorectal cancer. Secondary endpoints are to determine the safety and feasibility of this treatment and to establish the pharmacokinetic profile of intraperitoneally administered irinotecan. METHODS AND ANALYSIS: This phase I, '3+3' dose-escalation, study is performed in two Dutch tertiary referral centres. The study population consists of adult pa
Chemoradiation for advanced hypopharyngeal carcinoma: a retrospective study on efficacy, morbidity and quality of life
Chemoradiation (CRT) is a valuable treatment option for advanced hypopharyngeal squamous cell cancer (HSCC). However, long-term toxicity and quality of life (QOL) is scarcely reported. Therefore, efficacy, acute and long-term toxic effects, and long-term QOL of CRT for advanced HSCC were evaluated,using retrospective study and post-treatment quality of life questionnaires. in a tertiary hospital setting. Analysis was performed of 73 patients that had been treated with CRT. Toxicity was rated using the CTCAE score list. QOL questionnaires EORTC QLQ-C30, QLQ-H&N35, and VHI were analyzed. The most common acute toxic effects were dysphagia and mucositis. Dysphagia and xerostomia remained problematic during long-term follow-up. After 3Â years, the disease-specific survival was 41%, local disease control was 71%, and regional disease control was 97%. The results indicated that CRT for advanced HSCC is associated with high locoregional control and disease-specific survival. However, significant acute and long-term toxic effects occur, and organ preservation appears not necessarily equivalent to preservation of function and better QOL
