Adjuvant chemotherapy is recommended for patients with resected high-risk adult granulosa cell tumors (GCT), although strong data to support this are lacking. The objective of this study was to assess the outcomes of GCT patients, with the specific focus on patients that received adjuvant chemotherapy with curative intent (stage I-III), reported in a large national cancer registry. Data from the Surveillance, Epidemiology, and End Results (SEER) database between 2000 and 2013 were used for analysis. Patient and disease characteristics were extracted and analyzed for association with administration of chemotherapy...

OBJECTIVE: To report the clinical characteristics of 12 patients with limbic encephalitis (LE) who were antibody-negative after a comprehensive immunological study. METHODS: Review of clinical records of 163 patients with LE. Immunohistochemistry on rat brain, cultured neurons, and cell-based assays were used to identify neuronal autoantibodies. Patients were included if 1) there was adequate clinical, CSF, and MRI information to classify the syndrome as LE, 2) MRI images were accesible for central review, and 3) serum and CSF were available and confirmed negative for neuronal antibodies...

BACKGROUND: Operative management of pancreatic ductal adenocarcinoma (PDAC) is complicated by several key decisions during the procedure. Identification of metastatic disease at the outset and, when none is found, complete (R0) resection of primary tumor are key to optimizing clinical outcomes. The use of tumor-targeted molecular imaging, based on photoacoustic and fluorescence optical imaging, can provide crucial information to the surgeon. The first-in-human use of multimodality molecular imaging for intraoperative detection of pancreatic cancer is reported using cetuximab-IRDye800, a near-infrared fluorescent agent that binds to epidermal growth factor receptor...

To investigate the epidemiology, demographics and survival of mucinous adenocarcinomas (MACs), we identified 80,758 MAC patients in the Surveillance, Epidemiology and End Results (SEER) database. The reported incidence of MACs ebbed and flowed over time; however, a significant increase in reported annual age-adjusted incidences of MACs in the appendix, lung and bronchus was observed from 1981 to 2014. The demographics and outcomes of MACs differed by anatomic sites. MACs of the stomach had the largest percentage of poorly differentiated or undifferentiated tumors (41...

Sarcomas are a heterogeneous group of malignancies that arise from cells of a mesenchymal origin. Surgery forms the mainstay of the treatment of most patients with localized sarcoma and might be followed or preceded by chemotherapy and/or radiotherapy. In the metastatic setting, systemic treatments tend to improve survival and control symptoms. However, the adverse events and sometimes disappointing outcomes associated with these empirical approaches to treatment indicate a need for new approaches. The advent of next-generation sequencing (NGS) has enabled more targeted treatment of many malignancies based on the presence of specific alterations...

Recent studies are discovering TP53 mutations with gain of function (GOF) properties that promote tumorigenesis via a variety of mechanisms. To our knowledge, all reported compound mutations are allelic. We identified two patients with biallelic GOF TP53 mutations in their tumors and a third with allelic compound variants. The correlation with p53 expression was also examined. Genomic DNA was extracted from formalin-fixed, paraffin-embedded tissue and mutational analysis was performed using Ion AmpliSeq™Cancer HotSpot Panel V2...

The aim of this prospective registry-based population study was to investigate the association between QoL 3 years after surgery for rectal cancer and intrusive thoughts and to assess the association with the type of surgery (i.e., APE or ELAPE) in a population-based national cohort. ELAPE has been proposed as a superior surgical technique for distal rectal cancer, but long-term effects on QoL are not known. There are also no studies on the association of negative intrusive thoughts on patients' self-reported Quality of Life following surgery for distal rectal cancer...

FBXW7 is well characterized as a tumor suppressor in many human cancers including melanoma; however, the mechanisms of tumor suppressive function have not been fully elucidated. We leveraged two distinct RNA sequencing datasets: human melanoma cell lines (n=10) with control versus silenced FBXW7 and a cohort of human melanoma tumor samples (n=51) in order to define the transcriptomic fingerprint regulated by FBXW7. Here, we report that loss of FBXW7 enhances a mitochondrial gene transcriptional program that is dependent on MITF in human melanoma and confers poor patient outcomes...

OBJECTIVE: Randomized studies have not demonstrated a survival benefit of routine lymph node dissection in early-stage endometrial cancer. Many surgeons nevertheless perform lymph node dissection in all patients with early-stage endometrial cancer. This study aimed to ascertain the survival outcomes of very low-risk endometrial cancer patients (by the Korean Gynecologic Oncology Group [KGOG] criteria) who did not undergo lymph node dissection. MATERIALS AND METHODS: Medical records of 156 consecutive patients who underwent surgical staging without lymph node dissection were collected from 10 institutions...

BACKGROUND: Methadone is an attractive medication for treating children with advanced cancer with pain as it is the only long-acting opioid available as a liquid. However, it is not frequently used due to concerns about potential toxicities and side effects. OBJECTIVE: Evaluate the efficacy and safety of methadone as the first long-acting opioid in children with advanced cancer. DESIGN: Retrospective chart review of 52 consecutive patients referred to Pediatric Supportive Care for pain management started on methadone as their first long-acting opioid...

BACKGROUND: The aim of this study was to review the oncological and functional outcomes of new and established primary focal treatments (FT) for localized prostate cancer (PCa). METHODS: We performed a systematic search of published studies on FT for localized PCa using electronic databases (Medline and Embase). These studies included reports on hemiablation, focal ablation and target-ablation. We excluded salvage focal therapy studies and limited the search to those with a minimum of 12 months of follow-up...

Immunotherapy prolongs survival in only a subset of melanoma patients, highlighting the need to better understand the driver tumor microenvironment. We conducted bioinformatic analyses of 703 transcriptomes to probe the immune landscape of primary cutaneous melanomas in a population-ascertained cohort. We identified and validated 6 immunologically distinct subgroups, with the largest having the lowest immune scores and the poorest survival. This poor-prognosis subgroup exhibited expression profiles consistent with β-catenin-mediated failure to recruit CD141+ DCs...

The pressing need for improved therapeutic outcomes provides a good rationale for identifying effective strategies for alimentary tract (AT) cancer treatment. The potential re-sensitivity property to chemo- and immunotherapy of low-dose decitabine has been evident both preclinically and in previous phase I trials. We conducted a phase Ib/II trial evaluating low-dose decitabine primed chemo-immunotherapy in patients with drug-resistant relapsed/refractory esophageal, gastric or colorectal cancers. Forty-five patients received either the 5-day decitabine treatment with subsequent re-administration of the previously resistant chemotherapy (decitabine primed chemotherapy, D-C cohort) or the aforementioned regimen followed by cytokine-induced killer cells therapy (decitabine primed chemotherapy and CIK treatment, D-C+CIK cohort) based on their treatment history...

BACKGROUND: Management of low rectal cancer continues to be a challenge, and decision making regarding the need for an abdominoperineal resection (APR) in patients with low-lying tumors is complicated. Furthermore, choices need to be made regarding need for modification of the surgical approach based on tumor anatomy and patient goals. DISCUSSION: In this article, we address patient selection, preoperative planning, and intraoperative technique required to perform the three types of abdominoperineal resections for rectal cancer: extrasphincteric, extralevator, and intersphincteric...

Initially reported in tropical regions, Cryptococcus gattii infection is now diagnosed globally. METHODS: case report; Literature review. Although initial reports described outbreaks of pulmonary and central nervous system (CNS) disease in tropical regions such as Australia and New Guinea, it is now clear that Cryptococcus gattii is a global, neurotropic pathogen. In contrast with C. neoformans, C. gattii patients are more likely to present with cryptococcomas in the brain and lungs and are often HIV negative...

PURPOSE: Although computed tomography (CT) is the imaging modality of choice for diagnosing colonic diverticulitis today, there remains a risk of colorectal cancer mimicking diverticulitis due to overlapping imaging features. Current practice guidelines recommend interval colonoscopy after diverticulitis to exclude occult malignancy. Some authors have suggested that this may be unnecessary in patients with uncomplicated diverticulitis. The aim of our study was to examine the prevalence of occult colorectal cancer in patients with CT-proven acute uncomplicated diverticulitis in an Asian population...

Background: Laparoscopic liver resection has been gaining momentum, and it has become an accepted practice after the two international consensus conferences where experts worked up guidelines to standardize this approach and improve its safety. However, most laparoscopic hepatectomies were performed in patients with liver metastases. The concurrent presence of liver cirrhosis with hepatocellular carcinoma (HCC) poses a great challenge to clinicians trying to establish a routine use of laparoscopic liver resection for HCC...
