OBJECTIVE: This study aimed to investigate clinicopathological responses and oncological outcome in patients receiving short- or long-course chemoradiotherapy (CRT) and to assess the predictive factor for recurrence in each treatment. METHODS: A total of 118 rectal cancer patients receiving preoperative CRT were enrolled. Clinicopathological responses and oncological outcome in patients receiving short- or long-course CRT were investigated. RESULTS: Despite there being no significant differences in the prognosis of disease-free survival (DFS) based on TNM stage classification in patients receiving long-course CRT, patients with advanced stage demonstrated poor DFS after short-course CRT...

Decision making is one of the most complex skills required of an oncologist and is affected by a broad range of parameters. For example, the wide variety of treatment options, with various outcomes, side-effects and costs present challenges in selecting the most appropriate treatment. Many treatment choices are affected by limited scientific evidence, availability of therapies or patient-specific factors. In the decision making process, standardized approaches can be useful, but a multitude of criteria are relevant to this process...

OBJECTIVE: Factors that predict rectal cancer metastasis to the lungs remain undefined. We investigated whether the lateral pelvic lymph node (LPN) sizes before and after chemoradiotherapy (CRT) correlate with lung metastasis after surgery for lower rectal cancer. METHODS: Two hundred and forty patients with lower rectal cancer who received preoperative CRT and curative surgery between 2003 and 2017 were examined. Computed tomography-measured LPN sizes before and after CRT were retrospectively determined by 1 colorectal surgeon who was blinded to the patients' clinical and pathological outcomes...

People with intellectual disabilities (PWIDs) are now living longer; thus, the incidence of cancer within this population is increasing. Available data indicate an excess of digestive tract cancers in PWIDs, but colorectal cancer has rarely been specifically studied and has not been extensively reviewed. This is despite risk factors such as being overweight, obesity, and lack of exercise being more frequent in PWIDs. In this article, we examine the literature on the frequency, screening, and treatment of colorectal cancer in PWIDs by as sessing 4 databases, Medline, EBSCO-CINHL, ASSIA, and PsychLIT, from 1970 to February 2017...

OBJECTIVE: Neoadjuvant therapy followed by surgery has been the standard treatment for advanced esophageal cancer. Severe toxicities may influence body composition, including skeletal muscle mass, and increase postoperative complications. The purpose of this study was to evaluate the influence of sarcopenia, changes in body composition, and adverse events during neoadjuvant chemotherapy (NACT) on postoperative complications in esophageal cancer patients. METHODS: A total of 83 patients with esophageal cancer undergoing NACT followed by esophagectomy were included...

OBJECTIVE: Pancreatic cancers are characterized by dense stroma. To estimate the degree of interference by coexisting noncancer cells in molecular analyses, we aimed to develop a DNA methylation marker that assesses a cancer cell fraction in DNA samples. METHODS: The microarray data of 22 pancreatic cancer tissues from the The Cancer Genome Atlas database and 9 noncancer tissues were used for genome-wide screening. Thirty-one surgical tumor samples (10 intraductal papillary mucinous neoplasms [IPMNs] and 21 pancreatic cancers), 4 normal, and 26 nontumor samples were used for validation...

OBJECTIVE: We previously reported that the largest diameter of retrieved lymph nodes (LNs) correlates with the number of LNs and is a prognostic factor in stage II colon cancer. We examine whether T, B, and natural killer (NK) cells in LNs are related to the number of LNs and survival. METHODS: The subjects comprised 320 patients with stage II colon cancer. An LN with the largest diameter was selected in each patient. The positive area ratios of cells that stained for CD3 and CD20, and the numbers of CD56-positive cells were measured...

OBJECTIVE: Esophageal cancer is one of the deadliest cancers in the world, and the main subtype is esophageal squamous cell carcinoma (ESCC), which comprises 90% of cases. Expression of tryptophan 2,3-dioxygenase (TDO2), an enzyme involved in tryptophan catabolism, has been linked with tumor survival and poor prognosis of brain and breast cancer. However, no studies have investigated the potential role of TDO2 in esophageal cancer. Here we explored the expression and biological significance of TDO2 in ESCC...

Progressive multifocal leukoencephalopathy (PML) is a fatal demyelinating disease associated with immunocompromised states. We describe a case of PML, which developed after prolonged ibrutinib use and a low burden of chronic lymphocytic leukemia disease. The delay in diagnosis of the patient despite multiple presentations to medical providers across different facilities suggests that there is a lack of awareness of PML as a potential complication of ibrutinib. Treatments with postulated anti-John Cunningham polyomavirus agents and IL-2 were ineffective, likely due to the advanced state of the patient's disease...

OBJECTIVE: The serum albumin-globulin ratio (AGR) is associated with malignancy outcomes. However, among patients with rectal cancer (RC) who undergo neoadjuvant chemoradiotherapy (nCRT), the clinical and prognostic significance of the pretreatment AGR is unclear. METHODS: We investigated whether the pre-nCRT AGR can help predict oncological outcomes in patients with RC receiving nCRT. We analyzed 114 patients with RC who received nCRT followed by total mesorectal excision at our institution...

Well-balanced levels of tyrosine phosphorylation, maintained by the reversible and coordinated actions of protein tyrosine kinases (PTKs) and protein tyrosine phosphatases (PTPs), are critical for a wide range of cellular processes including growth, differentiation, metabolism, migration, and survival. Aberrant tyrosine phosphorylation, as a result of a perturbed balance between the activities of PTKs and PTPs, is linked to the pathogenesis of numerous human diseases, including cancer, suggesting that PTPs may be innovative molecular targets for cancer treatment...

Liver metastases are very common in metastatic breast cancer (MBC); current treatments for these lesions are based on systemic chemotherapy, endocrine- or human epidermal growth factor receptor 2 (HER2)-targeted therapy, and palliative therapy. However, no standard approach has been clearly identified for second and further chemotherapy lines in MBC patients. In the phase III clinical trial EMBRACE, eribulin was particularly effective in reducing liver lesions and improving both overall survival and progression-free survival in liver MBC patients...

OBJECTIVES: Predictive factors of response to eribulin are lacking. We aimed to investigate the activity and safety of eribulin in a real-world population of metastatic breast cancer (MBC) patients and to identify possible predictive factors of progression-free survival (PFS) and objective response. METHODS: We retrospectively analyzed 71 eribulin-treated MBC patients. Best response rate, PFS, and adverse events (AEs) were evaluated. The impact of different clinical-pathological factors on PFS was evaluated using the Cox proportional hazards model...
