Mucinous adenocarcinoma of the bladder is rare. The most common symptoms are hematuria, suprapubic pain and dysuria. The patient in the present case was a 59-year-old female who presented with a tumor sized ~5.0×3.4 cm, located in the anterior bladder wall, which was pathologically diagnosed as mucinous bladder adenocarcinoma. The stage at presentation was considered to be advanced and inoperable, due to extensive local invasion. For this type of cancer, early diagnosis is crucial. If the cancer is limited to the bladder, the survival rate may exceed 75%...

The prognosis of recurrent and disseminated glioblastoma is very poor. Bevacizumab is an effective established therapy for recurrent glioblastoma following treatment with radiotherapy plus temozolomide. However, the efficacy of bevacizumab is limited to prolonging progression-free survival, without significant prolongation of the overall survival. We herein report a case of glioblastoma in a 32-year-old female patient with encephalocraniocutaneous lipomatosis (ECCL) that had disseminated following surgical resection and subsequent treatment with temozolomide and radiation therapy...

Non-Hodgkin lymphoma (NHL) is a primary tumor arising in lymph nodes and lymphoid tissue. The incidence of NHL is increasing at an annual rate of 3%. The human Jun activation domain-binding protein 1/COP9 signalosome subunit 5 (Jab1/CSN5) is a negative regulator of the cell cycle inhibitor p27(Kip1) and abnormal expression of Jab1 is correlated with reduced p27 expression and associated with advanced tumor stage and poor prognosis in several human cancers. F-box protein S-phase kinase-interacting protein-2 (Skp2), the substrate recognition subunit of the Skp1-Cul1-F-box protein ubiquitin protein ligase complex, is required for the ubiquitination and consequent degradation of p27...

The significance of diet for disease prevention has long been recognised. Dietary recommendations have therefore been integrated in health promotion messages. Gastrointestinal functioning is essential for the digestion of nutrients. Oxidative stress has been observed in patients with constipation, as well as in those with colorectal cancer, cardiovascular disease and other chronic illnesses associated with constipation. The coexistence of colorectal neoplasia and coronary artery disease has been incriminated for exposure to common risk factors associated with increased oxidative stress...

Insulinoma is a rare neuroendocrine tumor. Hypersomnia as the first presentation in a patient with insulinoma is even more rare and may be easy to misdiagnose. We are herein reporting a case of insulinoma initially presenting with prolonged sleep time and extreme difficulty in waking. The abovementioned symptoms occurred every 2-3 months. Over the last 2 months, the attacks had become more frequent and severe. On computed tomography examination, a 12×9-mm cystic nodule was detected in the uncinate process of the pancreas, which was pathologically diagnosed as insulinoma...

Breast and gynecological cancers and their treatment may cause lymphedema of the upper and lower extremities, respectively. We herein report the cases of two patients with lung adenocarcinoma who developed lymphedema of the lower extremities. One patient harbored an epidermal growth factor receptor mutation and the other patient harbored an anaplastic lymphoma kinase fusion gene. The patients had developed intra-abdominal lymph node metastases and received several lines of chemotherapy. In both patients, lymphedema in the lower extremities developed >30 months after the initiation of first-line chemotherapy...

In the present study, a case of acute cerebral infarction with radiation-induced carotid artery dissection is reported. Carotid artery dissection is generally asymptomatic at the early stages. Due to the non-specific clinical manifestations of carotid artery dissection, a detailed inquiry of the past history of a patient has a critical role in making a diagnosis of radiation-induced common carotid artery dissection. Onset of acute ischemic stroke is the predominant manifestation, and for patients with a history of head-and-neck radiotherapy, dissection should be considered...

Retroperitoneal inflammatory myofibroblastic tumor (IMT) is a rare lesion of unknown etiology. The management of IMT may be challenging due to its intermediate malignant potential, the possibility of local recurrence after surgical resection and its unique anatomic location, which makes radical resection impossible due to its proximity to vital structures. Thus, treatment for recurrence and metastasis mainly relies on chemotherapy. We herein report a case of a 60-year-old man with an IMT sized 6.7×5.1 cm, located in the left adrenal area, which was identified by a computed tomography (CT) scan of the abdomen...

We herein report the case of a 74 year-old woman with a diffuse large B-cell lymphoma and bilateral renal masses identified on computed tomography scans during the initial staging process. Following partial bilateral nephrectomy, histopathological examination revealed renal cell carcinoma (RCC) and oncocytoma in the left and the right kidneys, respectively. Shortly afterwards, lymphoma of the left palatine tonsil was diagnosed and the patient received chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP regimen), followed by radiotherapy...

Transanal excision (TAE) for rectal tumors is increasingly applied and it is generally recommended that the defect following full-thickness excision should be closed. The aim of this study was to compare the complications and anal function following TAE between cases where the defect was closed and those where it was not. A total of 43 consecutive rectal malignant tumor patients eligible for TAE were investigated. Regarding anorectal function, incontinence was assessed using the Wexner score. The defect of the rectum was closed in 21 of the 43 patients...

Glioblastoma multiforme is the most common primary malignant brain tumor. The clinical outcome following diagnosis remains extremely poor. The treatment of choice is wide surgical resection of the visible tumor, frequently followed by adjuvant combined radiochemotherapy (RCTx) with temozolomide as the chemotherapeutic agent. Extracranial metastases are extremely rare, with <200 cases of extracranial metastases from glioblastoma multiforme reported in the literature to date. We herein present a case of a patient suffering from a fast-growing metastasis to the oral cavity, completely filling the buccal cavity within 2 weeks, as the only manifestation of recurrent glioblastoma multiforme following initial surgical resection and adjuvant RCTx...

In breast cancer with >4 positive axillary lymph nodes, it is common practice to deliver radiotherapy to the affected site following mastectomy. However, less is known regarding the benefits this may confer on women with 1-3 positive lymph nodes. In this meta-analysis, we aimed to assess whether post-mastectomy radiotherapy (PMRT) was beneficial for such patients. A literature review was conducted using the PubMed and Ovid databases. Selected studies were analysed and data regarding overall survival (OS) and locoregional recurrence (LRR) rates were extracted...

The role of trefoil factor 3 (intestinal) (TFF3) has been analyzed in numerous cancers, such as breast and gastrointestinal cancer, and has been associated with poor prognosis. However, the role of TFF3 in ovarian cancers is not clear. Expression analysis of TFF3 in 91 ovarian cancer patients was performed by immunohistochemistry of primary paraffin-embedded tumor samples. The results were scored according to staining intensity and percentage of positive tumor cells resulting in an immune-reactive score (IRS) of 0-12...

The average age when cervical cancer is diagnosed is decreasing, resulting in a larger proportion of patients seeking fertility preservation. Therefore, a less radical approach that aims to preserve the potential for fertility during the treatment of cervical carcinoma is crucial. The present study reported a case of a patient with stage IB2 cervical cancer who exhibited pathological complete regression to neoadjuvant chemotherapy (NACT). This patient underwent deep cervical conization and laparoscopic lymphadenectomy to preserve her fertility...

A 23-year-old man presented to our hospital with membranous nephropathy and received a detailed examination, including pleural biopsy, due to a feeling of chest oppression. The result of the pleural biopsy was malignant pleural mesothelioma. However, the patient did not have a history of asbestos or tobacco exposure. A review of the English literature identified only 7 reported cases of concomitant malignant mesothelioma and nephrotic syndrome. Furthermore, among the 7 cases reviewed, 6 had a history of asbestos exposure, 1 had a history of prolonged tobacco exposure and in only 1 case the renal pathology results revealed the presence of membranous nephropathy...
