Pulmonary Pleomorphic Carcinoma Mimicking Primary Sarcoma of the Neck: A Case Report and Literature Review.

We describe our challenge in diagnosing an unusual and rapidly progressing case of pulmonary pleomorphic carcinoma (PPC)-a rare, poorly differentiated, or undifferentiated non-small-cell carcinoma that can metastasize locally or distantly and has a poor prognosis. Our patient was an elderly man with a one-month history of abdominal pain, anorexia, and weight loss, diagnosed with atrophic gastritis via endoscopy, and treated medically without improvement. A week later, this patient developed pain in the head, neck, and shoulder area, and further examination revealed a thickening of his left neck and shoulder, with no palpable lymph nodes.

Successful multimodal treatment of intraoral salivary duct carcinoma in a patient with multiple lymph node metastases: a case report.

Background: Salivary duct carcinoma (SDC) is a high-grade salivary gland malignancy that is associated with an aggressive clinical behavior and poor prognosis. Herein, we report on a long surviving case of SDC of the minor salivary gland with multiple lymph node metastases (LNMs).

Case Presentation: An 83-year-old woman presented with a history of lymphadenopathy in the right side of the neck and recent onset and rapid growth of a mass in the right buccal region.

Neutrophil/lymphocyte ratio as a prognostic indicator of hepatic arterial infusion chemotherapy with arterial cisplatin plus continuous 5-fluorouracil.

Aim: Hepatic arterial infusion (HAIC) therapy may be a therapeutic option for advanced hepatocellular carcinoma (HCC) in addition to administration of sorafenib, which is the only currently established standard regimen for this disease. Survival benefit of HAIC has been reported in patients positive for antitumor response. Therefore, the prediction of antitumor response is important in decision-making for HAIC treatment.

Predictive value of optimal morphologic response to first-line chemotherapy in patients with colorectal liver metastases.

Background: It has been reported that morphologic response to preoperative chemotherapy is an independent prognostic factor in patients who undergo hepatic resection of colorectal liver metastases (CLM). The aim of this study was to evaluate the predictive value of morphologic response to first-line chemotherapy in patients with CLM.

Methods: We assessed 41 patients with CLM who received fluorouracil-based chemotherapy with or without bevacizumab as the first-line chemotherapy between April 2006 and June 2012.

Response to intra-arterial cisplatin and concurrent radiotherapy in a patient with primary mucosal malignant melanoma of the nasal cavity.

Background: The prognosis for patients with mucosal malignant melanoma (MMM) of the nasal cavity is very poor because of the radioresistance of melanoma cells.

Methods: We present the first case report of the efficacy of superselective intra-arterial cisplatin (CDDP) infusion concurrent with hypofractionated radiotherapy (RT) for MMM of the nasal cavity.

Results: A pink, polypoid mass, histopathologically diagnosed as an amelanostic melanoma, occupied the right nasal cavity.

An essential dose of cisplatin for super-selective intra-arterial infusion concomitant with radiotherapy in patient with maxillary squamous cell carcinoma.

The present study investigated the efficacy and safety of using a lower dose of cisplatin (CDDP) in super-selective intra-arterial concurrent chemoradiotherapy (SSIACRT) to treat maxillary squamous cell carcinoma. 10 patients with maxillary squamous cell carcinoma (T3 n = 6, T4a n = 4) without regional or distant metastasis were treated by SSIACRT. The CDDP dose per course was 100 mg/body, i.

Flow-sensitive alternating inversion recovery (fair) imaging for retrograde cortical venous drainage related to intracranial dural arteriovenous fistula.

Introduction: To evaluate the hypothesis that flow-sensitive alternating inversion recovery (FAIR) magnetic resonance (MR) imaging can detect retrograde cortical venous drainage (RCVD) in patients with intracranial dural arteriovenous fistula (DAVF).

Methods: Seven patients with angiographically confirmed DAVF with RCVD and two DAVF patients without RCVD underwent examinations with conventional MR imaging and FAIR, five of these seven patients with RCVD also underwent examination with dynamic susceptibility contrast (DSC) MR imaging. The ability of FAIR to depict prominent cerebral veins was evaluated, and FAIR was compared with the relative cerebral blood volume (rCBV) maps created with DSC.

Dural arteriovenous fistula involving the transverse sigmoid sinus after treatment: assessment with magnetic resonance digital subtraction angiography.

Introduction: The purpose of this study was to evaluate the utility of magnetic resonance digital subtraction angiography (MRDSA) in showing the presence or absence of retrograde venous drainage (RVD) in patients with intracranial dural arteriovenous fistula (DAVF) involving the transverse sigmoid sinus (TSS) after treatment.

Methods: Of 16 patients with DAVF involving the TSS, 13 underwent digital subtraction angiography (DSA) and MRDSA before and after treatment, and 3 underwent DSA before treatment and DSA and MRDSA after treatment. Five patients underwent these procedures twice after treatment.

The radiotoxicity of 131I therapy of thyroid cancer: assessment by micronucleus assay of B lymphocytes.

Unlabelled: We investigated cytologic radiation damage in thyroid cancer after (131)I therapy using micronucleus assay (MNA) of B lymphocytes exclusively, as opposed to our previous study in which MNA of all lymphocyte subsets was used.

Methods: We studied 22 thyroid cancer patients treated with 3.7 GBq of (131)I.
