An 84-year-old man was referred to our hospital with swollen right cervical lymph nodes. Computed tomography showed right supraclavicular and mediastinal lymph node enlargement, and fluorodeoxyglucose positronemissiontomography showed multiple areas of abnormally increased radioactivity inthe right supraclavicular and mediastinal lymph nodes, right ninth rib, and left fifth and seventh ribs. Biopsy of the right supraclavicular lymph node revealed metastatic adenocarcinoma with partial immunohistochemical staining for prostate specific antigen (PSA)...

Presacral myelolipomas are rare, benign, asymptomatic tumors composed of mature adipose tissue and hematopoietic elements. Presacral myelolipomas can occur in patients with a medical history of malignancy, steroid use, and/or endocrine disorders including diabetes mellitus. A 65-year-old man with no specific medical history experienced temporal abdominal pain without bowel symptoms that lasted a few hours. By the time he visited a hospital, the pain had diminished. Computed tomography failed to detect any abnormality in the abdominal or pelvic organs that would have caused the abdominal pain but revealed a lesion 4 cm in diameter in the frontal sacrum...

Purpose: To report the efficacy and late side effects(LSEs) of CT-based image-guided brachytherapy for the treatment of cervical cancer. Materials: Between 2008 and 2014, 100 patients with FIGO stage IIB-IVA cervical carcinoma were analyzed. The patients received pelvic irradiation (45-50 Gy in 25 fractions) with concurrent chemotherapy, whereas the mean prescribed EBRT dose, including initial and boost doses to positive lymph nodes, ranged from 54 to 64 Gy. Afterwards, intracavitary(IC) or combined intracavitary/interstitial(IC/IS) brachytherapy was performed using a CT-based procedure with prescribed doses of 6 or 8 Gy in 3-7 fractions...

BACKGROUND: It is not clear whether all patients with rectal cancer need chemoradiotherapy. A restrictive use of neoadjuvant chemoradiotherapy (nCRT) based on MRI findings for rectal cancer was investigated in this study. METHODS: This prospective multicentre observational study included patients with stage cT2-4 rectal cancer, with any cN and cM0 status. Carcinomas in the middle and lower third that were 1 mm or less from the mesorectal fascia, all cT4 tumours, and all cT3 tumours of the lower third were classified as high risk, and these patients received nCRT followed by total mesorectal excision (TME)...

Ketamine, lidocaine, and mexiletine are potential nonopioid adjuvant medications for the use of refractory cancer-related pain, particularly when opioids are demonstrating limited objective benefit. This is a case report of a single patient admitted to a large academic medical center in the United States. The patient is a 43-year-old woman with a history of Crohn's disease complicated by rectal squamous cell carcinoma and complex, progressive, and intractable pelvic and rectal pain. Over the course of hospitalization, her pain demonstrated limited opioid responsiveness despite marked fluctuations of her oral morphine equivalent doses...

MicroRNAs (miRNAs) are post-transcriptional regulators of gene expression that target mRNAs for translational repression or cleavage. The present study was conducted to identify differentially expressed miRNAs in primary tumor tissues of rectal carcinoma (RC) that may be associated with heterochrony hepatic metastasis (HHM). Samples were collected exclusively from patients with RC but not colon cancer (CC); Next-generation high-throughput sequencing technology and bioinformatics tools were used to profile and analyze small RNAs and their corresponding targets in primary tumor tissues with HHM (n=2) or without metastases (non-metastatic, NM; n=2)...

BACKGROUND There is now evidence to support that some cases of high-grade serous papillary carcinoma arise from the fallopian tubes rather than the ovaries. Common symptoms at presentation include abdominal pain and swelling, vomiting, altered bowel habit and urinary symptoms. To our knowledge, this is the first case of serous papillary carcinoma presenting as a vaginal mass lesion. CASE REPORT A 41-year-old woman was referred to the Bnai-Zion Medical Center with the main complaint of irregular vaginal bleeding, vaginal mucous discharge, and suspected pelvic mass...

INTRODUCTION: Extramural vascular invasion (EMVI) is associated with a poor prognosis in patients with rectal carcinoma. Patients with proven vascular invasion have a shorter progression-free survival and overall survival. Until recently, vascular invasion had been identified primarily by pathologists. Currently, EMVI can be detected preoperatively by magnetic resonance imaging used for rectal cancer staging. Our study aimed at verifying the effect of pre-operative EMVI detection on PFS after resection and comparing this interval (PFS) to the group of patients with vascular invasion identified and confirmed by pathologists...

The incidence and mortality of colorectal carcinoma are rising in young adults. This population-based propensity matching study aimed to compare long-term oncological outcomes of local excision with radical resection for early localized colorectal cancer (CRC) in young patients without preoperative chemoradiotherapy. Patients under 45 years old with T1 colon or rectal adenocarcinoma who underwent local excision or radical resection were included from the Surveillance, Epidemiology, and End Results (SEER) database between 1998 and 2014...

Metastatic disease to the stomach or duodenum is an infrequent diagnosis, and head and neck squamous cell carcinoma (HNSCC) is one of the least common primary malignancies that lead to gastric or duodenal metastases. We report the case of a 65-year-old man with human immunodeficiency virus infection and previously diagnosed HNSCC who presented with melena. The patient had a percutaneous endoscopic gastrostomy tube placed 3 months prior to his presentation. Laboratory testing was significant for normocytic anemia and a digital rectal examination was positive for melena...

BACKGROUND: Colorectal cancer (CRC) is a leading cause of cancer-related death. The biologic response of CRC to standard of care adjuvant therapies such as chemotherapy and radiation are poorly understood. MicroRNAs (miRs) have been shown to affect CRC progression and metastasis. Therefore, we hypothesized that specific miRs modulate CRC response to chemoradiation. METHODS: In this study, we used miR expression profiling and discovered a set of microRNAs upregulated rapidly in response to either a single 2 Gy dose fraction or a 10 Gy dose of γ-radiation in mouse colorectal carcinoma models...

INTRODUCTION: The demographic trend will lead to an increase of elderly persons in Germany in the future. The population is becoming smaller and older because of the deficiency in childbirths. This results in demographic ageing of the population in Germany. Studies addressing patients ≥ 85 years, the oldest old, are becoming more and more important. MATERIALS AND METHODS: The prospectively collected data of 141 patients ≥ 85 years with colorectal carcinoma treated between 1995 and 2014 were analysed retrospectively...

BACKGROUND: Surrogate endpoints in rectal cancer after preoperative chemoradiation are lacking as their statistical validation poses major challenges, including confirmation based on large phase 3 trials. We examined the prognostic role and individual-level surrogacy of neoadjuvant rectal (NAR) score that incorporates weighted cT, ypT and ypN categories for disease-free survival (DFS) in 1191 patients with rectal carcinoma treated within the CAO/ARO/AIO-04 phase 3 trial. PATIENTS AND METHODS: Cox regression models adjusted for treatment arm, resection status, and NAR score were used in multivariable analysis...

Gut microbiota, a group of 1014 bacteria, eukaryotes and virus living in gastrointestinal tract, is crucial for many physiological processes in particular plays an important role in inflammatory and immune reactions. Several internal and external factors can influence this population, and shifts in their composition, have been demonstrated to contribute and affect different diseases. During dysbiosis several bacteria related to inflammation, one of the most necessary factors in carcinogenesis; it has been shown that some bacterial strains through deregulation of different signals/pathways may affect tumor development through the production of many factors...

BACKGROUND: Mucinous rectal carcinoma has been reported to have a lower survival rate and a poorer histologic response to chemoradiotherapy(CRT). Magnetic resonance imaging (MRI) can accurately evaluate the amount of mucin pools (MP) in primary cancer tissue. We compared the degree of MP on MRI before and after CRT with the histologic findings of resected specimens to investigate the predictors of response to CRT. METHODS: The study group comprised 205 patients with rectal adenocarcinoma who received preoperative CRT...

We investigated the anti-metastatic action of nicotine- and tar-removed cigarette smoke extract (CSE) on highly metastatic mouse Colon-26 cells using syngeneic BALB/c mice. Colon-26 cells were injected into the spleen of mice, cells were grown in the spleen as the primary lesion, and some metastasized from the spleen to liver and established a metastatic lesion. CSE (10, 30, and 100%) was intraperitoneally administered daily to the mice for 14 days after tumor inoculation. As a result, the relative spleen weights of CSE-administered mice did not differ significantly from those of the control mice...
