CONTEXT Synchronous malignancies affecting both the major and minor papilla are rare and are usually of endocrine origin. CASE REPORT A 60-year-old female presented with a two-week history of progressive jaundice and pruritus. Evaluation revealed features of a periampullary malignancy. A Whipple pancreaticoduodenectomy was done. There was a growth in the ampulla of Vater and another in the re...
Nivolumab is an immune checkpoint inhibitor with demonstrated efficacy against several malignant tumors. Alterations in driver oncogenes such as EGFR and ALK are a poor prognostic factor in nivolumab therapy for non-small cell lung cancer (NSCLC), whereas a smoking history is a well-known, favorable prognostic factor. However, an efficacy of nivolumab therapy for multiple primary malignant tumo...
BACKGROUND A new entity of patients with recurrent prostate cancer limited to a small number of active metastatic lesions is having growing interest: the oligometastatic patients. Patients with oligometastatic disease could eventually be managed by treating all the active lesions with local therapy, i.e. either surgery or ablative stereotactic body radiotherapy. This study aims to assess the im...
Synchronous primary neoplasms detected on 18F-FDG PET in staging of patients with esophageal cancer.
UNLABELLED Because of improvements in diagnostic technology, the incidental detection of synchronous primary tumors during the preoperative work-up of patients with esophageal cancer has increased. The aim of this study was to determine the rate and clinical relevance of synchronous neoplasms seen on (18)F-FDG PET in staging of esophageal cancer. METHODS From January 1996 to July 2004, 366 pa...
This study was conducted to investigate the clinicopathological features of synchronous cancers and treatment options according to their locations.Records of 8368 patients with colorectal cancer treated at our center between July 2003 and December 2010 were analyzed retrospectively. All synchronous colorectal cancer patients who underwent surgical treatment were included.Synchronous cancers wer...
BACKGROUND Malignant pleural mesothelioma (MPM) is an uncommon malignant tumor, and its synchronous occurrence with primary lung cancer is extremely rare. Here, we report the first surgical case of synchronous MPM and contralateral lung adenocarcinoma. Extrapleural pneumonectomy (EPP) combined with surgery for contralateral lung cancer may not be tolerated, and a lung-sparing procedure includin...
A case of synchronous metastasis of breast cancer to the stomach and colon is reported. A 38-year-old woman with a history of bilateral breast cancer was admitted for endoscopic examination because of occult blood. Endoscopic examination showed elevated lesions on the mucosal surface of the stomach and cecum. Histopathological examination of the biopsy specimens obtained from both sites showed ...
Spindle cell carcinoma (SpCC) is referred to as a variant of oral squamous cell carcinoma. It is also known as "sarcomatoid squamous cell carcinoma" because it consists of normal squamous carcinoma cells with spindle-shaped cells that appear similar to a sarcoma. The term, "second primary tumor" (SPT) or "double primary tumor", is proposed for a second tumor that develops independently from the...
Distant metastasis in patients with rectal cancer remains a problem influencing prognosis. Prediction of synchronous distant metastasis is important for the choice of personalized treatment strategies and postoperative follow-up protocol. So far, there are few studies about the predictive value of MRI features combined with clinical characteristics for synchronous distant metastasis in rectal c...
