PURPOSE/OBJECTIVE: Chemo-radiotherapy is an established primary curative treatment for anal cancer, but clinically equal rationale for different target doses exists. If joint preferences (physician and patient) are used to determine acceptable tradeoffs in radiotherapy treatment planning, multiple dose plans must be simultaneously explored. We quantified the degree to which different toxicity priorities might be incorporated into treatment plan selection, to elucidate the feasible decision space for shared decision making in anal cancer radiotherapy...

BACKGROUND: Gene electrotrotransfer describes the use of electric pulses to transfer DNA to cells. Particularly skeletal muscle has potential for systemic secretion of therapeutic proteins. Gene electrotransfer to muscle using the integrin inhibitor plasmid AMEP (Antiangiogenic MEtargidin Peptide) was investigated in a phase I dose escalation study. Primary objective was safety. MATERIAL AND METHODS: Patients with metastatic or locally advanced solid tumors, without further standard treatments available, were treated with once-only gene electrotransfer of plasmid AMEP to the femoral muscle...

BACKGROUND: The European Organization for Research and Treatment of Cancer (EORTC) 62012 study was a Phase III trial of doxorubicin versus doxorubicin-ifosfamide chemotherapy in 455 patients with advanced soft tissue sarcoma (STS). Analysis of the main study showed that combination chemotherapy improved tumor response and progression-free survival, but differences in overall survival (OS) were not statistically significant. We analyzed factors prognostic for tumor response and OS, and assessed histological subgroup and tumor grade as predictive factors to identify patients more likely to benefit from combination chemotherapy...

BACKGROUND: For tumours near organs at risk, there is concern about unintended increase in biological dose from elevated linear energy transfer (LET) at the distal end of treatment fields. The objective of this study was therefore to investigate how different paediatric posterior fossa tumour locations impact LET and biological dose to the brainstem during intensity-modulated proton therapy (IMPT). MATERIAL AND METHODS: Multiple IMPT plans were generated for four different simulated tumour locations relative to the brainstem for a five-year-old male patient...

BACKGROUND: In patients with prostate cancer (PCa), the lack of clear guidelines on the use of radiotherapy after radical prostatectomy (RP) invites unwanted variation of this treatment. We describe the hazard ratios and probabilities related to the use of post-RP radiotherapy. MATERIAL AND METHODS: Data were collected from the Cancer Registry of Norway and nine radiotherapy units. All patients were diagnosed with a non-metastatic PCa from January 2004 through June 2011...

BACKGROUND: The Nordic countries are similar in terms of demographics and health care organization. Yet there are marked differences in lung cancer mortality, for which Denmark historically has had the poorest outcome. One of several possible reasons for these differences could have to do with how lung cancer is diagnosed and treated in the different Nordic countries. However, among the four most populous Nordic countries: Sweden, Denmark, Norway and Finland, there is a paucity of knowledge about differences and similarities in recommendations in the national guidelines for non-small cell lung cancer (NSCLC) and the methodology by which the guidelines are developed...

BACKGROUND: Inter-fractional variation in urinary bladder volumes during the course of radiotherapy (RT) for prostate cancer causes deviations between planned and delivered doses. This study compared planned versus daily cone-beam CT (CBCT)-based spatial bladder dose distributions, for prostate cancer patients receiving local prostate treatment (local treatment) versus prostate including pelvic lymph node irradiation (pelvic treatment). MATERIAL AND METHODS: Twenty-seven patients (N = 15 local treatment; N = 12 pelvic treatment) were treated using daily image-guided RT (1...

INTRODUCTION: Geometrical uncertainties can result in a delivered dose to the tumor different from that estimated in the static treatment plan. The purpose of this project was to investigate the accuracy of the dose calculated to the clinical target volume (CTV) with the dose-shift approximation, in stereotactic body radiation therapy (SBRT) of lung tumors considering setup errors and breathing motion. The dose-shift method was compared with a beam-shift method with dose recalculation...

BACKGROUND: Despite the negative impacts of several cancer treatments on fertility, many patients do not recall having fertility-related discussions with their physicians. This study was conducted to identify those factors related to physicians' discussing the treatment impacts on fertility with cancer patients of reproductive age. MATERIAL AND METHODS: In this nationwide survey of cancer care physicians (n = 329, response rate 55%), oncologists and hematologists (mainly) completed a questionnaire on practice behavior, barriers, attitudes and confidence in knowledge regarding treatment-related fertility risks...

BACKGROUND: Patients with cancer are often treated by many healthcare providers, receive complex and potentially toxic treatments that can increase the risk for iatrogenic harm. The aim of this study is to investigate whether hospitalised cancer patients are at higher risk of adverse events (AEs) compared to a general hospital population. MATERIAL AND METHODS: A total of 6720 patient records were retrospectively reviewed comparing AEs in hospitalised cancer patients to a general hospital population in Norway, using the IHI Global Trigger Tool method...

BACKGROUND: The worldwide incidence of esophageal cancer has greatly increased over the past few decades making it the sixth deadliest cancer. The disease is often detected in advanced stages when surgery is no longer an option. The standard treatment in these situations is combined chemoradiotherapy, by employing drug cocktails that lead to optimal treatment outcomes both from the perspective of tumor control and normal tissue toxicity. METHODS: The aim of this work was to collate the existing trials and clinical studies reported on non-operable esophageal cancer and to analyze the results based on treatment outcomes after various drug combinations...

PURPOSE: To assess the effect of additional magnetic resonance imaging (MRI) alongside the planning computed tomography (CT) scan on target volume delineation in pancreatic cancer patients. MATERIAL AND METHODS: Eight observers (radiation oncologists) from six institutions delineated the gross tumor volume (GTV) on 3DCT, and internal GTV (iGTV) on 4DCT of four pancreatic cancer patients, while MRI was available in a second window (CT + MRI). Variations in volume, generalized conformity index (CIgen), and overall observer variation, expressed as standard deviation (SD) of the distances between delineated surfaces, were analyzed...

BACKGROUND: Oral carcinomas (OCs) make up a significant proportion of head and neck carcinomas (HNCs) and are an important cause of morbidity and mortality globally. The purpose of this population-based study was to determine trends in incidence and survival in OC in the Danish population from 1980 to 2014. MATERIAL AND METHODS: This study covered all patients registered in the nationwide Danish cancer registry (DCR) in the period 1980-2014. Age-adjusted incidence rate (AAIR) per 100,000 and annual percentage change (APC) were evaluated...

BACKGROUND: It is unknown whether smoking; age at time of radiotherapy or time since radiotherapy influence the intensity of late radiation-induced bowel syndromes. MATERIAL AND METHODS: We have previously identified 28 symptoms decreasing bowel health among 623 gynecological-cancer survivors (three to twelve years after radiotherapy) and 344 matched population-based controls. The 28 symptoms were grouped into five separate late bowel syndromes through factor analysis...

BACKGROUND: Long-term survival rates for most types of childhood cancers have improved dramatically over the past decades. However, because of advances in multimodality treatments, cancer survivors nowadays more often face long-term complications, including diminished gonadal and reproductive function. The aim of this study was to identify whether the use of fertility treatments among early onset (0-34 years) cancer survivors giving birth differed from that among siblings giving birth and to identify the subgroups of cancer survivors that were most likely to require fertility treatments...
