OBJECTIVE: To determine overall survival (OS) and factors associated with OS after pelvic exenteration for uterine cancer. METHODS: Women with uterine cancer who underwent exenteration (n=1160) were identified from the 1998-2011 National Cancer Data Base. Kaplan-Meier and multivariate Cox proportional-hazards survival analyses were performed to test for associations of potential explanatory variables with OS. Analyzed confounders included age, comorbidity score, insurance status, income, distance from home to treatment center, stage, distant and nodal metastasis, tumor size, surgical margin status, exenteration type, and treatment with radiation and/or chemotherapy...

BACKGROUND: Pathological stage and grade have limited ability to predict the outcomes of superficial urothelial bladder carcinoma at initial transurethral resection (TUR). AT-motif binding factor 1 (ATBF1) is a tumor suppressive transcription factor that is normally localized to the nucleus but has been detected in the cytoplasm in several cancers. Here, we examined the diagnostic value of the intracellular localization of ATBF1 as a marker for the identification of high risk urothelial bladder carcinoma...

Angiosarcomas are one of the rarest subtypes of sarcomas; those are malignant vascular tumors arising from vascular endothelial cells. Occurrence of intra-oral angiosarcoma is extremely rare (0.0077% of all cancers in Europe). We present here, to our knowledge, the first case of a 83-year-old man with gingival and both palatine tonsils localization of a grade-two angiosarcoma discovered after a two months history of a painful lesion followed by hematoma and spontaneous bleeding. Chemotherapy with paclitaxel and hemostatic radiotherapy were inefficient and he died seven months after the first symptoms...

Paratesticular malignant mesothelioma is an extremely rare type of mesothelioma with only a limited number of reported cases. Its clinical differentiation is challenging, and its diagnosis is almost exclusively accidental. The major risk factor is exposure to asbestos, typically with a long latency between exposure and diagnosis. The current study presents the clinical data of two patients diagnosed with paratesticular malignant mesothelioma. We evaluated a large spectrum of risk factors in the patients histories...

Basal cell carcinoma (BCC) typically occurs in sun-exposed sites. Only 16 individuals with umbilical BCC have been described in the literature, and the characteristics of patients with umbilical BCC are summarized. PubMed was used to search the following terms: abdomen, basal cell carcinoma, basal cell nevus syndrome, and umbilicus. Papers with these terms and references cited within these papers were reviewed. BCC of the umbilicus has been reported in five men and 11 women; one man had two tumors. Two patients had basal cell nevus syndrome (BCNS)...

Targeting pro-survival cell signaling components has been promising in cancer therapy, but the benefit of targeting with single agents is limited. For malignancies such as triple-negative breast cancer, there is a paucity of targets that are amenable to existing interventions as they are devoid of the human epidermal growth factor receptor 2 (HER2), progesterone receptor (PR), and estrogen receptor (ER). Concurrent targeting of cell signaling entities other than HER2, PR and ER with multiple agents may be more effective...

BACKGROUND: Small cell bladder cancer (SCBC) is an aggressive subtype accounting for less than 1 % of all bladder malignancies associated with rapid progression, early metastases formation and high mortality rates. CASE PRESENTATION: We present an unusual long term disease free survival of a 60 year-old man who was diagnosed with SCBC two and a half years ago. He underwent four cycles of cisplatin/etoposide chemotherapy as well as a prophylactic whole-brain radiotherapy followed by a radical cystoprostatectomy and ileal neobladder with extended pelvic lymphadenectomy...

BACKGROUND: In promoting tumour malignancy IL-6 signalling is considered to have an important role. However, the biological roles of IL-6 on radiosensitivity in oral squamous cell carcinoma (OSCC) remain largely unclear. The objective of this study is to determine the effects and molecular mechanisms of IL-6 on radiosensitivity in OSCC. METHODS: Two OSCC cell lines, and OSCC tissue samples with radioresistant cells were used. We examined the effects of IL-6, or tocilizumab, a humanised anti-human IL-6 receptor antibody, or both on radiosensitivity and DNA damage after X-ray irradiation in vitro...

Glioblastoma is the most-common cancer in the brain and with an increasing incidence. Despite major advances in the field, there is no curative therapy for GB to date. Many solid tumors, including GB, experienced metabolic reprogramming in order to sustain uncontrolled proliferation, hypoxic conditions and angiogenesis. PPARs, member of the steroid hormone receptor superfamily, are particularly involved in the control of energetic metabolism, particularly lipid metabolism, which has been reported deregulated in gliomas...

Malignant salivary gland tumours of the larynx are very rare, with limited reports of clinical outcomes. We present the decade-long experience of a single institution. A 10-year retrospective chart review of a tertiary head and neck cancer centre was performed. Index patients were identified from a review of a pathology database, and reviewed by a head and neck pathologist. Patient demographics, presenting signs and symptoms, treatment modalities and clinical outcomes were extracted from electronic medical records...

Non-small cell lung cancer (NSCLC) is the second most common solid malignancy in the United States of America, and the leading cause of cancer-related mortality. Nearly 15% of patients present with early-stage disease, for which the standard of care is lobectomy. However, the median age at diagnosis ranges from 65 to 74 years, and many patients have significant comorbidities that preclude surgical treatment. Previously, the standard of care for these patients was definitive radiotherapy (RT) with conventional fractionation (i...

BACKGROUND: Nephroblastoma (Wilms' tumor [WT]) is the most common malignant renal cancer in children. Although the outcome of WT has significantly improved as a result of the combination of surgery, chemotherapy, and radiotherapy; in some cases WT results in severe complications. Thus, novel strategies that would decrease treatment burden are required. The aim of the current study was to investigate the synergistic antitumor effect of andrographolide (AND) in combination with vincristine (VCR) on WT cells...

PURPOSE : Non-melanotic skin cancers remain the most commonly diagnosed cancers. Radiotherapy and surgery are the most common treatment options. Radiotherapy has a recurrence rate of up to 20% for basal or squamous cell cancers. One of the difficulties is to determine the extent of disease for poorly demarcated tumors. This study utilizes protoporphyrin (PpIX) fluorescence to provide information on the extent of subclinical disease for poorly demarcated tumors treated with radiotherapy...

We report on a 72-year-old male patient who developed sarcoidosis of the mediastinal lymph nodes, the liver, and the prostate 11 years ago. Seven years later, he underwent transurethral resection of the prostate by laser due to hematuria. Pathology of the resected chips showed a 'granulomatous prostatitis with epitheloid cells'. Malignancy was histologically excluded at that time. Four years later, he was diagnosed with an undifferentiated prostate carcinoma, with a Gleason score of 5 + 4 = 9. After initiation of antihormonal therapy, he underwent radical prostatectomy and pelvic lymphadenectomy, which revealed a pT3b pN1 carcinoma with infiltrated resection margins...

PURPOSE: Neuroendocrine cervical cancer is a rare malignancy with a poor prognosis, yet there is a paucity of data to guide treatment decisions when managing patients with this diagnosis. Specifically, there are little data to aid practitioners in deciding if there is added value to brachytherapy given the additional time, cost, discomfort, and toxicity to patients. METHODS AND MATERIALS: We used the National Cancer Data Base to identify women with locally advanced neuroendocrine cervical cancer treated with definitive chemoradiotherapy to determine if the addition of brachytherapy improves outcomes in this disease...
