Oxaliplatin given systemically is associated with pneumonitis in less than 1% of cases. This case report describes acute respiratory failure, due to bronchiolitis organising pneumonia, in a patient with colorectal carcinoma being treated with hyperthermic intraperitoneal chemotherapy which included oxaliplatin and CPT-11 (irinotecan). The clinical course, the lack of an identifiable infectious agent and the complete response to corticosteroids suggested a drug-induced cause. After ruling out CPT-11, oxaliplatin was considered to be the causal agent...

First degree relatives (FDRs) of colorectal cancer (CRC) patients are at higher risks of developing the disease, but screening rates amongst this group remains dismal. We undertook a systematic review of qualitative studies to identify the barriers surrounding CRC screening among FDRs from both the FDRs' and the healthcare professionals' perspectives. A comprehensive search of major bibliographic databases from January 2000 till February 2017 was performed to answer the above research questions. Pre-determined inclusion and exclusion criteria were applied...

Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal neoplasm of the gastrointestinal tract. The stomach is most commonly affected. Advances in immunopathology have identified a mutation in the c-KIT proto-oncogene, leading to the development of the tyrosine-kinase inhibitor Imatinib as targeted therapy for advanced disease. Surgery, however, remains the only curative treatment of resectable primary GIST. This review article aims at reviewing the management of primary GISTs, investigating recurrences, exploring the role of surgery in metastatic disease and looking into combined surgery and molecular therapy for GISTs...

The multidisciplinary management of locoregional esophagogastric cancers (GCs) has evolved significantly over the past two decades. While perioperative chemotherapy, adjuvant chemotherapy, and postoperative chemotherapy with chemoradiation (CRT) have demonstrated improved survival when compared to surgery alone, there is no universal standard for resectable gastroesophageal cancer. Current global management patterns vary by geographic region, partly related to phase III data originating from each global region...

Familial adenomatous polyposis (FAP) is an autosomal dominant genetic condition, caused by mutations in the adenomatous polyposis coli ( APC ) tumor suppressor gene. Desmoid tumors (DTs) are seen in 15% to 20% of FAP patients. Specific location of mutation serves as a guide to predict colonic and extra colonic manifestations and their aggressiveness. A severe FAP-phenotypic family was registered in a genetic counselling high-risk Uruguayan hereditary cancer clinic. Proband's DNA was analysed by NGS, detecting a pathogenic mutation in APC gene...

Background: Surgical resection is the standard of care for intrahepatic cholangiocarcinoma (ICC), but only a minority of patients are managed surgically. Other modalities, including external beam radiation (XRT), radiofrequency ablation (RFA), and radioactive implants (RIs) have been employed with significant heterogeneity of prognosis reported in the literature. The aim of this study was to evaluate the demographics of patients with ICC managed non-surgically and compare prognosis in patients managed surgically to those that underwent XRT, RFA, or RI...

Background: Current guidelines recommend chemotherapy (CT) with or without radiotherapy (RT) for unresected intrahepatic cholangiocarcinoma (IC). Although there is currently lack of consensus, previous smaller studies have illustrated the efficacy of local therapy for this population. This investigation evaluated outcomes of chemoradiotherapy (CRT) versus CT alone in unresected IC using a large, contemporary national database. Methods: The National Cancer Data Base (NCDB) was queried for primary IC cases (2004-2013) receiving CT alone or CRT...

Background: Palliative care has been associated with improved survival and quality of life, with lower rate of end-of-life health care utilization and cost. We examined trends in palliative care utilization in older pancreatic cancer patients. Methods: Pancreatic cancer patients with and without palliative care consults were identified using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database between 2000 and 2009. Trend of palliative care use was studied...

Background: The cancer micro-environment is recognized as having an increasing importance in cancer progression. Immune cells originating from the peripheral blood are important elements of this environment. Thrombocytosis, neutrophilia and lymphocytopenia have been found to be negative prognostic indicators in many cancers. This study aims to evaluate the potential of the use of a novel hematological marker, the platelet-neutrophil to lymphocyte ratio (PNLR) as a practical, reliable, and inexpensive prognostic tool in metastatic colorectal adenocarcinomas...

Background: Chemoradiotherapy for anal cancer (AC) can incur substantial treatment-related toxicities. Whereas radiotherapy (RT) for AC has historically been delivered with two- or three-dimensional conformal RT (2D/3DCRT) techniques, intensity-modulated RT (IMRT) is associated with improved target conformality and lower doses to organs-at-risk (OARs). This is the first investigation to date evaluating trends of IMRT utilization in the United States. Methods: The National Cancer Data Base (NCDB) was queried [2004-2015] for AC patients receiving definitive chemoradiotherapy with a defined RT technique (3DCRT versus IMRT)...

Background: Genetic determinants are considered as driving forces in development colorectal cancer (CRC), a malignancy that ranks as the second cause of cancer death in the world. Single nucleotide polymorphisms (SNPs), are considered as the main genetic factor in cancers susceptibility. MicroRNAs are critical players in posttranslational gene regulation by binding to their specific recognition sequences located at 3' untranslated region (UTR) of mRNAs. In present study we have elucidated the role of 9,850 A > G (rs4648298), in development of sporadic CRC in Iranian population...

Background: Management of rectal cancer with involved lateral pelvic lymph nodes (LPLNs) at the time of diagnosis-the stage we refer institutionally to as Stage 3.5-is controversial. The American Joint Committee on Cancer's 7th edition classifies internal iliac lymph nodes (LNs) as regional (Stage III), but both external and common iliac LNs as metastatic (Stage IV). However, in many Asian countries all LPLNs are considered regional and patients are treated with curative intent, with literature supporting improved outcomes with LPLN dissection...

Background: Accurate staging is crucial for management of patients with newly diagnosed rectal cancer. Endorectal ultrasound (EUS) has been the standard modality in the United States for decades, with magnetic resonance imaging (MRI) now preferred by national guidelines. Positron emission tomography (PET), conversely, is not recommended. The current utilization of imaging modalities by American radiation oncologists in staging newly diagnosed rectal cancer is unknown. Methods: American radiation oncologists completed an anonymous institutional review board-approved online survey probing their imaging preferences for initial staging of rectal cancer patients...

Background: Adjuvant chemotherapy at concurrent time with radiation therapy (RT) or at adjuvant time alone in locally advanced rectal cancer (LARC) is used with several regimens. The cost-utility analysis was conducted to compare administration of two 5-FU regimens and capecitabine in the aspect of provider and societal viewpoint. Methods: Stage II or III rectal cancer patients who received pre-operative or post-operative concurrent chemoradiotherapy and adjuvant chemotherapy were compared by using decision tree model between (I) 5-FU plus leucovorin (LV) for 5 days per cycle (Mayo Clinic regimen); (II) 5-FU continuous infusion (CI) for 120-h per cycle (CAO/ARO/AIO-94 protocol); (III) standard regimen of capecitabine...

Background: The correlation between DPYD*9A (c.85T>C) genotype and dihydropyrimidine dehydrogenase (DPD) deficiency clinical phenotype is controversial. Reference laboratories either did not perform DPYD*9A genotyping or have stopped DPYD*9A genotyping and limited genotyping to high-risk variants (DPYD*2A, DPYD*13 and DPYD*9B) only. This study explored DPYD*9A genotype and clinical phenotype correlation in patients with gastrointestinal (GI) malignancies treated with fluoropyrimidines...
