AIMS AND BACKGROUND Esophageal cancer patients with pathologic lymph node involvement generally have a poor prognosis. Many randomized controlled trials have not achieved consistent results similar to those of the RTOG8501 trial, and the long-term survival rate has not increased. The present study aimed to compare the efficacy and toxic side effects of concurrent chemoradiotherapy and radiother...
OBJECTIVE To determine the incidence of minor and major complications in patients with squamous cell carcinoma of the upper aerodigestive tract who require surgical salvage or planned neck dissection after an initial treatment regimen with radiotherapy or concurrent chemoradiotherapy for organ preservation. DESIGN The medical records of 100 patients treated in a phase 3 trial comparing radiot...
BACKGROUND Surgical resection is the preferred treatment of potentially curable esophageal cancer. To improve long term patient outcome, many institutes apply neoadjuvant chemoradiotherapy. In a large proportion of patients no response to chemoradiotherapy is achieved. These patients suffer from toxic and ineffective neoadjuvant treatment, while appropriate surgical therapy is delayed. For this...
BACKGROUND The benefit of neoadjuvant chemoradiotherapy in oesophageal cancer has been extensively studied but data on survival are still equivocal. OBJECTIVE To assess the effectiveness of chemoradiotherapy followed by surgery in the reduction of mortality in patients with resectable oesophageal cancer. METHODS Computerised bibliographic searches of MEDLINE and CANCERLIT (1970-2002) were s...
AIMS AND BACKGROUND Little is known about chemoradiotherapy in elderly patients with locally advanced esophageal cancer. We compared the efficacy and toxicity of chemoradiotherapy in elderly and non-elderly patients with locally advanced esophageal cancer and determined the variables affecting the treatment outcome in the elderly patients with locally advanced esophageal cancer who had received...
BACKGROUND Hematological markers of the systemic inflammatory response (SIR) including the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and the combination of NLR with PLR (CNP) are associated with prognosis of patients with esophageal squamous cell carcinoma (ESCC). However, their value in predicting the sensitivity to chemoradiotherapy in patients with ESCC is unc...
BACKGROUND It has become increasingly common to incorporate adjuvant chemotherapy with radiotherapy in the treatment of resected anaplastic astrocytoma based on results from recent phase II/III randomized trials. However, whether or not combined chemoradiotherapy is associated with improved survival outcome in patients who undergo "biopsy only" is less clear. METHODS The US National Cancer Da...
Platinum-based chemotherapy is considered a standard treatment option for patients with metastatic esophageal carcinoma. However, the overall survival of patients receiving such treatment is <1 year. A common presenting symptom of esophageal cancer is dysphagia, which has a substantial impact on quality of life. We have now retrospectively evaluated the efficacy and safety of palliative chemora...
Neoadjuvant chemoradiotherapy has been introduced in patients with surgically resected rectal cancer and reduced the local recurrence. Heterogeneity exists in rectal cancer, and we hypothesized that there are subclones resistant to chemoradiotherapy within the cancer mass. We performed DNA-targeted sequencing of pre- and post-treatment tumor tissues obtained from 20 rectal cancer patients who r...
Background. Little data on directly comparing chemoradiotherapy with observation has yet been published in the setting of adjuvant therapy for resected gastric cancer who underwent D2 lymphadenectomy. The present indirect comparison aims to provide more evidence on comparing the two approaches. Methods. We conducted a systematic review of randomized controlled trials, extracted time-to-event da...
