Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease resulting from infection of oligodendrocytes in the central nervous system with John Cunningham virus. Although PML is commonly diagnosed in immunocompromised patients with human immunodeficiency virus, it can also arise in other immunodeficient states. In this report, we present an unusual case of PML occurring 40years after chemoradiation therapy for Hodgkin lymphoma in a patient with normal total lymphocyte counts on annual surveillance...

Recurrent respiratory papillomatosis (RRP) is a disease of the respiratory tract caused by infection with the human papillomavirus (HPV) and is characterized by multiple recurring papillomas throughout the respiratory tract. Although rare, extra laryngeal involvement carries the risk of malignant transformation in 3-7% of adults. We report the case of a patient with unmonitored juvenile onset RRP with pulmonary involvement found to have malignant transformation to squamous cell carcinoma (SCC). Incidentally found on chest radiography for mild chest wall trauma, she was found to have a large left lower lobe mass with pathology consistent with SCC...

BACKGROUND: Glioblastoma multiforme (GBM) is the most common malignant primary brain tumor, with an incidence of 3.19 cases per 100,000 person years and remarkably poor prognosis showing a 5-year survival rate of 4-5%, and only a 26-33% survival rate at 2 years in clinical trials. OBJECTIVE: In this paper, we review the different types of treatment modalities based on the relevant databases. Methods of diagnosis will be described briefly. METHOD: Systemic compilation of the relevant literature...

BACKGROUND: Advances in cancer immunotherapy have generated encouraging results in multiple malignancies refractory to standard chemotherapies. As the use of immune checkpoint inhibitors (ICI) proliferates, the incidence of autoimmune side effects associated with these agents, termed immune related adverse events (irAE), is expected to increase. The frequency of significant irAE in ICI treated patients is about 10-20% and early recognition is critical to prevent serious morbidity and even mortality...

Many patients with pancreatic cancer are not candidates for surgical resection due to involvement of critical mesenteric vascular structures. We compare and contrast the commonly used classification systems for borderline resectable and locally advanced pancreatic cancer. We describe the current strategies in managing venous and arterial involvement, as well as the role of neoadjuvant chemotherapy and chemoradiation, before explanding on a novel clinical trial in this patient population.

The treatment of gastric cancer requires a multimodal approach to decrease the risk of locoregional and distant recurrence. The optimal timing of chemotherapy, surgery, and radiation therapy continues to be explored in ongoing trials. In the United States, surgical resection is often followed by adjuvant chemoradiation therapy or by a combination of neoadjuvant and adjuvant chemotherapy. Here we report on 4 patients with resected gastric adenocarcinoma who were treated with a combination of these 2 approaches, receiving neoadjuvant chemotherapy followed by adjuvant chemoradiation therapy...

Anal squamous cell carcinomas (ASCC) are increasing in frequency across the developed world, and 70-90% of all cases originate from infection with human papilloma viruses (HPV). Primary chemoradiotherapy (CRT) is the standard treatment for ASCC, but local and/or distant failure still occurs in up to 30% of patients. HPV-associated ASCC and tumors with a higher density of tumor infiltrating lymphocytes (TIL) carry a better prognosis. Furthermore, HPV can render tumors more immunogenic, whereas it correlates with elevated TIL densities...

The outcome of patients with locally advanced, resectable gastric cancer, or adenocarcinoma of the gastroesophageal junction is poor. In clinical trials, multimodality therapy, such as perioperative chemotherapy, preoperative or postoperative chemoradiation, or adjuvant chemotherapy led to significant increments in survival. Therefore, experts agree that patients with stage II or III disease should be offered a multidisciplinary treatment approach. However, patients are treated somewhat differently in the different regions of the world and survival rates remain far from being satisfactory...

OBJECTIVES: The purpose of this study was to determine the optimal timing of surgical resection of oesophageal adenocarcinoma following neoadjuvant chemoradiotherapy (nCRT). METHODS: nCRT before resection of oesophageal adenocarcinoma yields improved overall and progression-free survival. Despite the wide acceptance of tri-modal therapy, the optimal timing of surgical resection after nCRT is not well defined and existing studies are limited. Adults with Stage II/III oesophageal adenocarcinoma undergoing nCRT before surgery were identified from the National Cancer Database...

OBJECTIVE: Radical trachelectomy is a valid alternative for the treatment of early-stage cervical cancer in young women who wish to preserve fertility potential. Recent data indicate that even less radical surgery could be performed in low-risk cases. The objective of our study was to evaluate the safety of simple vaginal trachelectomy and node assessment in patients with low-risk, early-stage cervical cancer (<2 cm). METHODS: From May 2007 to July 2016, 35 women underwent a simple vaginal trachelectomy with laparoscopic sentinel lymph node mapping + pelvic node dissection...

Diffuse WHO grade II gliomas are histologically and genetically heterogeneous. The 2016 WHO classification redefines grade II gliomas with respect to morphological and molecular tumour alterations: grade II oligodendrogliomas are defined by the presence of whole-arm codeletion in chromosomal arms 1p/19q, whereas isocitrate dehydrogenase (IDH) mutations define subclasses of astrocytoma. Although histological grade remains useful, the prognoses of patients with glioma are more tightly associated with molecular alterations than with grade, and chromosomal and gene array technologies are becoming increasingly beneficial in understanding tumour genetic heterogeneity...

BACKGROUND: Further optimisation of present standard chemoradiation is needed in patients with locally advanced rectal cancer. Veliparib, an oral poly(ADP-ribose) polymerase inhibitor, has been shown to enhance the antitumour activity of chemotherapy and radiotherapy in preclinical models. We aimed to establish the maximum tolerated dose and establish the recommended phase 2 dose of veliparib combined with neoadjuvant capecitabine and radiotherapy. METHODS: This phase 1b, open-label, multicentre, dose-escalation study was done at six hospitals (one in Australia and five in the USA)...

Esophageal cancer is an aggressive malignancy with increasing incidence, and the prognosis of patients treated by surgery alone remains dismal. Preoperative treatment can modestly prolong overall survival. Preoperative chemotherapy or chemoradiation is the standard of care for resectable esophageal cancer (greater than clinical stage I and less than clinical stage IV). One of the challenges is to predict complete response in the surgical specimen from preoperative therapy and to avoid surgery in some patients but also predict ineffectiveness of preoperative therapy if the tumor is resistant and avoid such therapies altogether...
