RATIONALE: Less than 1% of breast carcinomas metastasize to the gastrointestinal tract. The diagnosis is frequently not recognized especially when the history of breast carcinoma is remote. PATIENT CONCERNS: A 61-year-old female with a remote history of breast carcinoma presented with a 3-month history of change in bowel habits. Colonoscopy showed a circumferential rectal mass with initial impression of primary rectal cancer. MRI of the rectum showed findings that are atypical for primary rectal cancer...

A 78-year-old man was treated with laparoscopic partial nephrectomy for a 4 cm tumour in the lower pole of the left kidney. The patient was discharged 2 days postoperatively. Preoperatively there was no sign of metastasis; the pathology indicated complete removal of the tumour, a renal cell carcinoma. 53 days postoperatively the patient had acute onset of rectal bleeding. A colonoscopy revealed necrosis and three clips on the wall of the colon corresponding to where the descending colon passes over the left kidney...

INTRODUCTION: Low anterior resection (LAR) with total mesorectal excision (TME) represents the gold standard for patients with low rectal carcinoma. Protective ileostomy (PI) is commonly performed during LAR in an effort to protect low rectal anastomosis. The aim of this study is to analyse outcomes in our own patient population, focusing on morbidity associated with PI. METHOD: A retrospective clinical study of patients operated on between 2013 and 2015 was conducted in University Hospital Ostrava...

INTRODUCTION: The introduction of total mesorectal excision (TME) in the 1980s was pivotal in the surgical treatment for rectal carcinoma (RC). Routinely applied TME led to a significant reduction in the incidence of local recurrences. The purpose of our paper is to present the results of our non-randomized study comparing prospectively acquired data from radical resection / rectal extirpation using classic open access, laparoscopy and da Vinci robotic system. METHOD: The study group included 116 patients with RC who underwent radical surgical treatment between 1/2014-12/2016, after which the collected resection specimens were assessed in pathology laboratories of the referring hospital using the Quirkes protocol...

Some case reports of neuroendocrine tumors (NETs) and neuroendocrine carcinoma (NEC) associated with ulcerative colitis (UC) have been published. Most NET cases are small lesions corresponding to microcarcinoids (MCs). However, published case reports have presented findings of MCs as single-case reports. Thus, the frequency of MCs is still unclear. In this study, we described the clinical and morphological features of 14 cases of UC-associated MC and estimated the frequency of MC. Consecutive patients with UC who underwent complete removal of the large intestine were assessed, and 135 patients were selected...

BACKGROUND AND AIM: Colorectal endoscopic submucosal dissection (ESD) is recommended to be carried out only by endoscopists with sufficient experience in gastric ESD. However, early gastric carcinoma is less common in Western countries than in Japan, and endoscopic maneuverability differs between the stomach and colorectum. We assessed the feasibility of colorectal ESD carried out by endoscopists with no or little experience in gastric ESD. METHODS: We analyzed en bloc resection, R0 resection and perforation rates in 180 consecutive colorectal ESD carried out by three endoscopists who had no or <5 cases of experience in gastric ESD...

AIMS: The clinical outcome of patients with locally advanced rectal cancer submitted to neo-adjuvant chemo-radiotherapy (CRT) is influenced by tumour response to treatment, which is reflected by tumour regression grade (TRG) and post-treatment (y) TNM stage. Little is known on the prognostic value of pre-treatment histopathological features of the tumour which may be useful to discriminate potential non-responders and to design tailored therapeutic strategies. In this study, we aimed to investigate the prognostic role of poorly differentiated clusters (PDC) of neoplastic cells in pre-treatment biopsies of rectal cancer submitted to neo-adjuvant CRT...

Preoperative neoadjuvant chemoradiotherapy (nCRT) is the gold standard in locally advanced rectal cancer, only 10-30% of patients achieving benefits. Currently, there is a need of a reliable selection of markers for the identification of poor or non-responders prior to therapy. In this work, we compared protein profiles before therapy of patients differing in their responses to nCRT to find novel predictive markers of response to therapy. Patients were grouped into 3 groups according to their tumor regression grading (TRG) after surgery: 'TRG 1-2', good responders, 'TRG 3' and 'TRG 4', poor responders...

We report two cases of bacteremia due to Clostridium difficile from two French hospitals. The first patient with previously diagnosed rectal carcinoma underwent courses of chemotherapy, and antimicrobial treatment, and survived the C. difficile bacteremia. The second patient with colon perforation and newly diagnosed lung cancer underwent antimicrobial treatment in an ICU but died shortly after the episode of C. difficile bacteremia. A review of the literature allowed the identification of 137 cases of bacteremia between July 1962 and November 2016...

BACKGROUND: Localized rectal carcinoma is invasive, with surgical resection the standard treatment. The aim of this study was to determine the feasibility of a supervised presurgical exercise intervention in patients with rectal cancer prior to rectal resection. PATIENTS AND METHODS: Twelve patients volunteered to undertake twice-weekly aerobic and resistance exercise for ∼16 weeks prior to surgery. At baseline, presurgery, and ∼8 weeks postsurgery, muscle strength and physical performance, body composition, quality of life, and fatigue were assessed...

Purpose Blockade of the programmed cell death 1 (PDCD1, PD-1) immune checkpoint pathway can improve clinical outcomes in various malignancies. Evidence suggests that aspirin (a widely used nonsteroidal anti-inflammatory drug) not only prolongs colorectal cancer survival, but can also activate T cell-mediated antitumor immunity and synergize with immunotherapy through inhibition of prostaglandin E2 production. We hypothesized that the survival benefit associated with aspirin might be stronger in colorectal carcinoma with a lower CD274 (PDCD1 ligand 1, PD-L1) expression level that resulted in lower signaling of the immune checkpoint pathway...

Evidence suggests that activation of autophagy in neoplastic cells potentiates antitumor immunity through cross-presentation of tumor-associated antigens to T cells and release of immune mediators. The SQSTM1 (sequestosome 1, p62) protein is degraded by activated autophagy, and might enhance immune response to tumor cells. We hypothesized that tumor SQSTM1 expression level might be inversely associated with T-cell densities in colorectal carcinoma tissue. We evaluated tumor SQSTM1 expression by immunohistochemistry in 601 rectal and colon cancer cases within the Nurses' Health Study and Health Professionals Follow-up Study...

BACKGROUND: Anastomotic leak is the most dreaded septic complication of colorectal surgical procedures. Death is proportional to the time between occurrence and diagnosis of the leakage. Biomarkers, which may help to predict anastomotic leakage before appearance of its clinical features, may be beneficial in preventing adverse outcomes. This study investigates a biomarker that might be useful to predict rectal anastomotic leakage before its clinical presentation. PATIENTS AND METHODS: Serum procalcitonin and C-reactive protein (CRP) levels, bacterial proliferation, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels of drain fluid were evaluated in 50 consecutive patients who underwent low anterior resection without diverting ostomy for rectal carcinoma...

BACKGROUND: No standard chemotherapy regimen for advanced urothelial cancer has been established, except for cisplatin-based regimens. We report the case of a patient with double primary cancer, urothelial carcinoma of the upper urinary tract and colorectal cancer, who underwent oxaliplatin-based chemotherapies. CASE PRESENTATION: A 56-year-old Japanese man presented to our hospital with the diagnosis of a left renal pelvic tumor and rectal cancer. Several examinations including ureteroscopic biopsy and computed tomography-guided biopsy were performed; however, the diagnosis of renal pelvic cancer could not be made...

Actinomycosis is a rare chronic disease caused by a group of anaerobic Gram positive bacteria. It may mimic a neoplasia at various anatomical levels. A pelvic localization is exceptional but has an increasing incidence since the use of intrauterine devices. In such cases, pelvic actinomycosis may present as a gynecological or a lower colonic malignancy. For all atypical clinical, with a prominent infectious or inflammatory context, the diagnosis of actinomycosis must be suggested and discussed with the pathologist to whom the biopsy will be submitted...

PURPOSE: Preoperative short-course radiotherapy (SCRT) followed by surgery has shown advantage over surgery alone in patients with resectable rectal carcinoma (RC); however, the importance of the timing of surgery after SCRT has not been well defined. This study aimed to investigate the effect of this duration on treatment outcomes. METHODS: Patients who underwent surgery after SCRT (25 Gy/500 cGy/daily/5fr, monday-friday) for resectable and infraperitoneal rectal adenocarcinoma (T3N0/(+)) were included into the study...

BACKGROUND/AIMS: The local excision of early colorectal cancer is limited by the presence of lymph node metastasis (LNM). Signet-ring cell carcinomas (SRC) and mucinous adenocarcinomas (MAC) are two relatively infrequent histological subtypes. However, little is known about the predictors of LNM and prognosis to support the feasibility of local excision in early-stage SRC and MAC. METHODS: The Surveillance Epidemiology and End Results Database were used to identify all patients with pT1 adenocarcinomas, including conventional adenocarcinoma (AC), MAC, and SRC...

PURPOSE: A 23-year-old lady had an incompletely excised perianal sarcoma. Brachytherapy as the sole treatment, rather than further surgery or external beam radiotherapy, was considered to be the best option with the least morbidity. METHODS AND MATERIALS: Although brachytherapy techniques with iridium-192 for anal and rectal carcinoma are well described using a perianal template, the size of the template was not suitable for a two-plane implant that needed to be in situ for about 4 days...
