Hematologic malignancies of the gastrointestinal luminal tract

AbstractHematologic malignancies include several lymphoproliferative and myeloproliferative disorders, many of which are frequently encountered in current health care settings. These malignancies frequently affect the gastrointestinal (GI) tract, either by secondary extranodal or extramedullary extension to the GI tract, or as a primary process arising in the GI tract. In fact, the GI tract may represent the most common extranodal site of involvement in many of them, such as lymphoma. Furthermore, in the current era of improved cancer treatment and advanced transplant procedures with increased survival, it has been quite common to encounter GI involvement by these malignancies through the disease course. Post-transplant lymphoproliferative disorder following kidney transplantation, for example, very commonly involves the GI tract. Other conditions that can involve the GI tract include multiple myeloma, plasmacytoma, myeloid sarcoma, mastocytosis, and Castleman disease. Imaging diagnosis of these malignancies can be challenging, since they are much less common than primary GI cancers and both share many common imaging features as well. However, certain imaging features, particularly in combination with a matching clinical scenario, play a pivotal role in diagnosing these conditions and directing further evaluation. In this article, we review common and rare hematologic malignancies of the GI tract and discuss their pathophysiologic, clinical, and imaging features.

Publication date: Available online 28 January 2020Source: Urology Case ReportsAuthor(s): Shinro Hata, Satoki AbeAbstractIn the Checkmate-025 trial, nivolumab treatment prolonged overall survival among patients with previously treated advanced renal cell carcinoma (RCC) compared with treatment with everolimus. Although effective, nivolumab is associated with immune-related adverse events (irAEs). However, the occurrence of hematological irAEs is rare. Some studies have reported on nivolumab-induced thrombocytopenia. Nivolumab associated thrombocytopenia in almost all patients improved with administration of various drugs. H...

We present the case of pre-operative pelvic lymph node sampling with the use of MRI/TRUS fusion-guided biopsy at the time of prostate biopsy. Lymph node pathology revealed metastatic, poorly differentiated prostate cancer, concurrent with Gleason 4+5 disease showing perineural invasion. The use of MRI fusion guided biopsy for nodal sampling may be an effective method pre-operative staging and treatment planning for prostate adenocarcinoma.

ConclusionsThese voting results from a panel of prostate cancer experts can help clinicians and patients navigate controversial areas of advanced prostate management for which high-level evidence is sparse. However, diagnostic and treatment decisions should always be individualised based on patient-specific factors, such as disease extent and location, prior lines of therapy, comorbidities, and treatment preferences, together with current and emerging clinical evidence and logistic and economic constraints. Clinical trial enrolment for men with advanced prostate cancer should be strongly encouraged. Importantly, APCCC 2019...

KobrinAbstractSymptom awareness may improve cancer outcomes by prompting timely help-seeking and diagnosis. Research in the UK has shown lower symptom awareness among sociodemographic groups at higher risk of poor cancer outcomes; however, no population-based surveys in the US have assessed whether cancer symptom awareness varies across sociodemographic groups. We therefore examined associations between sociodemographic factors and recognition of 11 cancer symptoms using a novel populati...

The purpose of this study was to assess the cost-utility of available screening modalities starting at 40 years in the general population compared to standard screening at 50 years old. A decision tree modeling average-risk of the CRC in the United States population was constructed for the cost per quality-adjusted life year (QALY) of the five most common and ef...

In view of the stress on the body by surgery and recovery, it makes sense if patients are prepared before appropriately so that they can recover earlier and better. Prehabilitation prior to major surgery has attracted the attention of clinicians recently, and this review highlights the steps that need to be taken to implement a multidisciplinary...

CONCLUSIONS: Based on the available evidence, there is no increased risk of complications for elective hand surgery in patients with prior breast cancer treatment. Breast cancer patients with preexisting ipsilateral lymphedema carry slightly increased risk of postoperative infection and worsening lymphedema. It is the authors' opinion and recommendation that elective hand surgery with a tourniquet is not a contradiction in patients who have received previous breast cancer treatments.
