Radiotherapy and newly approved cancer drugs - A quantitative analysis of registered protocols for drugs approved for the treatment of solid tumors.

Background/purpose: To evaluate the usage of RT in trial protocols for anti-cancer drugs approved by the US Food and Drug Administration (FDA).

Methods: Drugs which had been granted an FDA approval between 2010 and 2017 for the treatment of solid tumors in adults were identified. Use of RT in relation to each drug's approval date was reviewed on ClinicalTrials.

Liquid profiling of circulating tumor DNA in colorectal cancer: steps needed to achieve its full clinical value as standard care.

The analysis of circulating tumor DNA (ctDNA) is at the threshold of implementation into standard care for colorectal cancer (CRC) patients. However, data about the clinical utility of liquid profiling (LP), its acceptance by clinicians, and its integration into clinical workflows in real-world settings remain limited. Here, LP tests requested as part of routine care since 2016 were retrospectively evaluated.

Gender aspects in cardiooncology.

Background: Cardiooncology is a relatively new subspeciality, investigating the side effects of cytoreductive therapies on the cardiovascular (CV) system. Gender differences are well known in oncological and CV diseases, but are less elucidated in cardiooncological collectives.

Methods: Five hundred and fifty-one patients (278 male, 273 female) with diagnosed cancer who underwent regular cardiological surveillance were enrolled in the 'MAnnheim Registry for CardioOncology' and followed over a median of 41 (95% confidence interval: 40-43) months.

Blood Cholesterol and Outcome of Patients with Cancer under Regular Cardiological Surveillance.

Cardiovascular (CV) diseases and cancer share several similarities, including common risk factors. In the present investigation we assessed the relationship between cholesterol levels and mortality in a cardiooncological collective. In total, 551 patients receiving anticancer treatment were followed over a median of 41 (95% CI 40, 43) months and underwent regular cardiological surveillance.

Prognostic Impact of Pretherapeutic Hemoglobin Levels on All-cause Mortality in Cardiooncology.

Background/aim: We investigated the prognostic impact of hemoglobin (Hb) levels in tumour patients receiving routine cardiological surveillance during anticancer treatment. The aim of the study was to identify independent predictors of all-cause mortality in a cardio-oncological collective.

Patients And Methods: A total of 551 patients (273 males, 278 females) were enrolled in the Mannheim Registry for Cardiooncology and were included in the present analysis.

Unfinished business: Terminated cancer trials and the relevance of treatment intent, sponsors and intervention types.

The aim of the study was to report on the association of trial sponsors with intervention type, treatment intent, recruitment success and reasons to terminate cancer trials. The ClinicalTrials database was searched for interventional Phase 3 cancer trials (01/2006-05/2017). Noncancer studies and ongoing studies were excluded, permanently suspended studies were counted as terminated.

Coprevalence and Incidence of Lung Cancer in Patients Screened for Abdominal Aortic Aneurysm.

Background/aim: Lung diseases are common in patients with abdominal aortic aneurysms (AAA). This study evaluates the prevalence of lung cancer (LC) in high-risk patients screened for AAA.

Patients And Methods: Six hundred and one male patients (≥65 years of age, cardiovascular high-risk profile) were enrolled and followed prospectively over a median of 16.

Disease-free survival as a surrogate for overall survival in neoadjuvant trials of gastroesophageal adenocarcinoma: Pooled analysis of individual patient data from randomised controlled trials.

Introduction: Disease-free survival (DFS) is increasingly being used as surrogate end-point for overall survival (OS) in cancer trials. So far, there has been no validation of the surrogacy of DFS for OS for neoadjuvant treatment of gastroesophageal adenocarcinoma.

Methods: The study uses individual patient data (IPD) from eight randomised controlled trials (RCTs) (n = 1126 patients) comparing neoadjuvant therapy followed by surgery with surgery alone for gastroesophageal adenocarcinoma.

Open-Label Phase II Evaluation of Imatinib in Primary Inoperable or Incompletely Resected and Recurrent Glioblastoma.

Purpose: Preclinical studies indicated that imatinib may have single-agent activity in glioblastoma through inhibition of tyrosine kinase activity and also that it might enhance the efficacy of radiotherapy. We therefore sought to investigate clinical efficacy in patients with newly diagnosed and recurrent glioblastoma in combination with radiotherapy.

Methods: We conducted a nonrandomized, 2-arm, open-label phase II trial including patients aged 18 years or older with an ECOG performance status of 0-2 that were either newly diagnosed (arm A) with a measurable tumor (i.

Therapeutic drug monitoring (TDM) of 5-fluorouracil (5-FU): new preanalytic aspects.

Background 5-Fluorouracil (5-FU) is frequently used for the treatment of gastrointestinal tumors. The pharmacological effect of 5-FU is influenced by genetic polymorphisms as well as differently dosed regimens. Currently, 5-FU is generally administered as a continuous infusion via an implanted port system using a body surface area (BSA)-based dose calculation.

Mass spectrometry based analytical quality assessment of serum and plasma specimens with patterns of endo- and exogenous peptides.

Background Inappropriate preanalytical sample handling is a major threat for any biomarker discovery approach. Blood specimens have a genuine proteolytic activity that leads to a time dependent decay of peptidic quality control markers (QCMs). The aim of this study was to identify QCMs for direct assessment of sample quality (DASQ) of serum and plasma specimens.

Influence of complete administration of adjuvant chemotherapy cycles on overall and disease-free survival in locally advanced rectal cancer: post hoc analysis of a randomized, multicenter, non-inferiority, phase 3 trial.

Background: A randomized trial demonstrated that capecitabine is at least as effective as fluorouracil in the adjuvant treatment of patients with locally advanced rectal cancer. However, not all patients receive all planned cycles of chemotherapy. Therefore it is of interest how complete or partial administration of chemotherapy influences oncological outcome.

Strengthening health data on a rare and heterogeneous disease: sarcoma incidence and histological subtypes in Germany.

Background: The population-based incidence of sarcoma and its histological subtypes in Germany is unknown. Up-to-date information on a disease with an incidence comparable to other cancer entities is of high public health relevance. The aim of this study was to determine this incidence and to detect significant changes in incidence trends using data from German epidemiological cancer registries.

Predictors of overall and recurrence-free survival after neoadjuvant chemotherapy for gastroesophageal adenocarcinoma: Pooled analysis of individual patient data (IPD) from randomized controlled trials (RCTs).

Background: Neoadjuvant chemotherapy improves prognosis of patients with locally advanced gastroesophageal adenocarcinoma. The aim of this study was to identify predictors for postoperative survival following neoadjuvant therapy. These could be useful in deciding about postoperative continuation of chemotherapy.

Effectiveness of regional hyperthermia with chemotherapy for high-risk retroperitoneal and abdominal soft-tissue sarcoma after complete surgical resection: a subgroup analysis of a randomized phase-III multicenter study.

Objective: To determine whether regional hyperthermia (RHT) in addition to chemotherapy improves local tumor control after macroscopically complete resection of abdominal or retroperitoneal high-risk sarcomas.

Background: Within the prospectively randomized EORTC 62961 phase-III trial, RHT and systemic chemotherapy significantly improved local progression-free survival (LPFS) and disease-free survival (DFS) in patients with abdominal and extremity sarcomas. That trial included macroscopically complete and R2 resections.

Positron emission tomography as a surrogate marker for evaluation of treatment response in patients with desmoid tumors under therapy with imatinib.

We used 2-deoxy-2-[(18)F] fluoro-D-glucose (FDG) positron emission tomography (PET) to evaluate patients with desmoid tumors undergoing therapy with imatinib. The study included 22 patients with progressive disease (PD) of a biopsy proven desmoid tumor treated orally with imatinib 800 mg daily. Patients were examined using PET prior to onset of therapy and during treatment.

Positron emission tomography in patients with aggressive fibromatosis/desmoid tumours undergoing therapy with imatinib.

Purpose: We used (18)F-FDG PET to evaluate the FDG uptake in patients with aggressive fibromatosis (AF, also known as desmoid tumours) undergoing therapy with imatinib (imatinib mesylate, Glivec).

Methods: The pilot study included nine patients with progressive AF receiving oral treatment with imatinib at a daily dose of 800 mg. Patients were examined using PET prior to the start of therapy and during imatinib treatment.

The use of fluorine-18 fluorodesoxyglycose-positron emission tomography for treatment monitoring in patients with soft tissue sarcomas.

Positron emission tomography (PET) using 2-deoxy-2-[(18)F] fluoro-D-glucose ((18)F-FDG) has been used with increased frequency in the care of patients with soft tissue sarcomas to predict malignant potential of tumours, prognosis of survival and response to chemotherapy. Although there are several other PET tracers, which have found limited use in sarcomas, this review focuses on the use of (18)F-FDG, which is the most common used tracer. Recent literature and developments covering major aspects of PET imaging in the management of patients with soft tissue sarcomas will be discussed in this review with focus on treatment monitoring.
