Background: Malignant pleural effusion is common in patients with advanced malignant tumor. The aim of this study is to analyze the characteristics of pleural metastasis of renal clear cell carcinoma, pleural effusion under medical thoracoscopy and the diagnostic value of interventional thoracoscopy-guided biopsy, and to improve the understanding of pleural metastasis of renal clear cell carcin...

conclusion the technical performance of pet scan is significantly higher than similar technologies for staging and treatment of nsclc. in addition, it might slightly improve the treatment process and lead to a small level of increase in the quality adjusted life year (qaly) gained by these patients making it cost-effective for the treatment of nsclc. results the total annual running cost of a p...

the coexistence of two malignancies is rarely seen. a little association between hematologic malignancies especially multiple myeloma and renal cell carcinoma has been reported in the recent past. several case series revealed a bidirectional association between these two malignancies which may be due to the common risk factors, similar cytokine growth requirements and clinical presentation. her...

we present a rare case with history of neurological symptoms due to multiple brain metastases and no urological symptoms. during patient evaluation for primary tumor, transitional cell carcinoma (tcc) of left renal pelvis was found. the patient underwent gamma knife stereotactic radio-surgery for the metastatic brain lesions. radical nephroureterectomy was performed, and a 4-cycle course of pac...

there is an impression that basal cell carcinomas (bcc) occurring in younger population may be of more invasive behavior in comparison to those arising in older patients. the purpose of this study was to investigate this hypothesis by comparing the histological types of bcc in a large cohort of young and old patients. a total of 287 histological reports and clinical records were evaluated. a co...

introduction: esophageal squamous-cell carcinoma (scc) is one of the most common malignancies in iran. to reduce the incidence of esophageal scc, it is important to recognize the controllable risk factors and prevent them. celiac disease is widely known as a possible risk factor for esophageal scc.  thus, we decided to assess the frequency of celiac disease in esophageal scc patients in north e...

conclusions primary scec is a rare and highly aggressive tumor. however, prognosis is poor and long-term survival is exceptional. crt could be an appropriate alternative to operation. patients and methods this brief report was carried out by reviewing the medical records of 22 patients with newly histologically proven scec that were treated between 2000 and 2010 at 2 tertiary academic hospitals...

it has been argued that oral lichen planus (olp) may increase the risk of oral cancer. patients with olp may be at an increased risk for developing of oscc (oral squamous cell carcinoma). here, the author reports a case of olp initially presenting with a clearly benign olp lesion that transformed into oscc over a course of 18 months. this report may provide a clear evidence for olp lesion as a ...

esophageal squamous cell carcinoma is a rather common cancer in northern iran. incidence of adenocarcinoma of esophagus has an increasing trend in iran. co-existence of both cancers in one patient is very rare. we report a middle age woman from northern iran with a typical presentation of esophageal cancer, who was found to have a dual esophageal cancer. the disease was found in the advanced st...

esophageal cancer (ec) is the eighth most common cancer and sixth most frequent cause of cancer mortality worldwide. esophageal squamous cell carcinoma (escc) is the most common type of ec. escc develops by progression from premalignant lesions, which are called esophageal squamous dysplasia (esd). prevention is the most effective strategy for controlling this disease. generally, two methods ma...
