Metachronous Rectum Metastases from Gastric Adenocarcinoma: A Case Report

Introduction. Hepatic metastases of gastric adenocarcinomas are frequently observed due to the drainage into portal vein. Intestinal metastases disseminate from gastrocolic and mesenteric ligaments but they are seen very rarely and in most cases detected in postmortem studies. Case Report. A 74-year-old female patient with no known history of disease. Her complaints on application were epigastric pain, burning, and constipation. Gastroscopy showed a submucosal mass in the greater curvature of fundus and in colonoscopy, a mass with polypoid appearance that narrows the lumen at the rectum was detected. No far metastases or pathology were detected. Pathology report from gastric biopsy material demonstrated well-differentiated adenocarcinoma. Cytokeratin 7 (CK7) was found to be extensively strongly positive, Cytokeratin 20 (CK20) was negative in the immunohistochemical staining of the biopsy obtained from rectosigmoid area. Conclusion. Gastric cancer is among the frequent cancers today, most of which are adenocarcinomas. Although most of the metastases are observed in the liver, lungs, lymph nodes, and peritoneum, it should be remembered that intestinal metastases may be seen without the presence of any other metastatic focus. Our case is the first in literature reporting a rectum metastasis without any other organ metastasis

A comparison of patient characteristics, prognosis, treatment modalities, and survival according to age group in gastric cancer patients

Abstract Background The aim of this study was to investigate age-specific incidence rates and to compare disease stage, treatment, and survival according to age group in patients with gastric adenocarcinoma. Methods Gastric cancer patients treated at our hospital between 1999 and 2010 were retrospectively evaluated. We divided the cases into two subgroups: group 1 consisted of patients older than 70 years at the time of treatment, and group 2 included patients aged 70 years or younger. In all, 151 patients over 70 years of age and 715 patients age 70 years or younger were analyzed. Categorical and continuous variables were summarized using descriptive statistics and compared using statistical software. Overall survival rates were estimated via the Kaplan-Meier method. Results Median age at diagnosis was 58 years (range: 22 to 90 years). Between 1999 and 2002 the annual median age for patients aged older than70 years was 9.8%, which increased to 20% between 2007 and 2010. The one-year survival rate for patients with metastatic disease (stage IV) was 10.9% (95% CI: 8.9% to 12.9%) and 27.8% (95% CI: 17.3% to 38.2%) in groups 1 and 2, respectively (P = 0.015). The five-year survival rate for patients with non-metastatic disease (in whom curative surgery was performed) was 15.5% (95% CI = 12% to 19%) and 26.9% (95% CI = 25.9% to 27.9%) in groups 1 and 2, respectively (P = 0.03). There were no significant differences in gender, tumor localization in the stomach, tumor histology, perineural invasion (PNI), lymphovascular invasion (LVI), tumor stage, or type of surgery between the two groups. However, fewer of the patients in group 1 underwent adjuvant treatment (P = 0.02) and palliative chemotherapy (P = 0.007) than group 2 patients that were non-metastatic and metastatic at presentation, respectively. Conclusions Groups 1 and 2 were similar in terms of histopathological features and surgical modality; however, the survival rate was lower in group 1 than in group 2. The incidence of gastric cancer was higher in the patients older than 70 years of age. Additional randomized studies are needed to further assess the safety and clinical benefit of chemotherapy in gastric cancer patients older than70 years of age.</p

Gastric cancer: A case study in Turkey

Objective: The aim of this study was to determine age-specific incidence ratios, gastric cancer localization trend, histologic subtype and cancer related survival that whether have changed during the period from 1999 to 2010. Materials and Methods: A total of 866 gastric cancer patients treated at the hospital were retrospectively evaluated. Categorical and continuous variables were summarized using descriptive statistics and were compared using the Chi-square and Mann-Whitney U-tests, respectively. Cancer related survival rates were estimated by the Kaplan-Meier method. Results: The median age at diagnosis was 58 years. Trends concerning the median ages of the patients were increased (from 57 years to 59 years). The proportion of diffuse histological subtype gastric adenocarcinoma increased during the period from 1999 to 2010, and it was 27% between 1999 and 2002 and 32% between 2007 and 2010 (P = 0.04). The proportion of gastric adenocarcinoma localized in cardia increased during the period from 1999 to 2010, and was 7.2% between 1999 and 2002; and 22.5% in 2007 and 2010 (P = 0.004). For stage I that was diagnosed between 1999 and 2002, the relative survival was 67% and in patients diagnosed between 2007 and 2010 the rate was 85%. For stage II that was diagnosed between 1999 and 2002, the relative survival was 35% and in patients diagnosed between 2007 and 2010, the rate was 65%. Cox regression analysis was conducted based on age subgroup, diagnosis time, and gastric localization (proximal/distal) and for adenocarcinoma subtypes. Hazard ratio was 31.6 for stage IV (confidence interval [CI] = 10-42), 1.3 for cardia localization (CI = 1.04-1.6) and 1.37 for patients who had been diagnosed between 1999 and 2002 (1.14-1.78). Conclusions: The ratio of median age at diagnosis and proximal gastric adenocarcinoma, diffuse histologic subtype increased between 1999 and 2010. Cancer related survival significantly improved for stage I and stage II. Cardia localization and time of diagnosis between 1999 and 2002 had significantly poor outcome on relative survival

What is the optimal treatment in clinical stage T3N0M0 rectal cancer?

WOS: 000334153000014PubMed ID: 24659649Purpose: Some previous studies suggested that certain rectal cancer patients with stage T3N0 and favorable features may be adequately treated with surgery and adjuvant chemotherapy. However, the optimal management of clinical (c) T3N0 rectal adenocarcinoma based on preoperative imaging is unclear. In this study, we aimed to determine the frequency of lymph node metastases in patients clinically staged as T3N0 rectal adenocarcinoma following preoperative chemoradiotherapy (CTR). Methods: The medical records of 105 patients with clinico-imaging stage T3N0M0 rectal cancer who received preoperative CRT between 2004-2011 were retrospectively analyzed. Chemotherapy used concurrently with preoperative radiotherapy (RT) was protracted 5-fluorouracil (5FU) infusion. Results: Twenty-seven percent of the patients clinically staged as T3N0 before preoperative CRT had pathological (p) lymph node involvement on surgical material. The rate of pathological lymph node involvement was 0% in pT1, 20% in pT2, 35% in pT3 and 34% in pT4 patients. A significant association was demonstrated between pT stages and pN status (p=-0.03). Conclusion: Our study demonstrated that the accuracy of preoperative imaging for staging rectal cancer is limited because at least 27% of the patients may have undetected lymph node involvement after preoperative CRT in surgical material

Preoperative versus postoperative chemoradiotherapy in stage T3, N0 rectal cancer

WOS: 000343887400016PubMed ID: 24218281The study populations of previous preoperative chemoradiotherapy (pre-CRT) studies have consisted of mixed clinical stages, such as cT3-cT4 and/or cN positive. For this reason, it has not been possible to demonstrate whether pre-CRT is of benefit for individual subgroups. The medical records of 137 rectal cancer patients with clinical stage T3, N0 disease who received either pre-CRT or postoperative chemoradiotherapy (post-CRT) between 2002 and 2011 were retrospectively analyzed. The regimen of pre-CRT consisted of slow fluorouracil (5FU) infusion and that of post-CRT consisted of bolus 5FU and leucovorin concurrent with radiation. Following pre-CRT, significant downstaging was achieved. However, administration of pre-CRT did not influence the type of surgical resection in tumours a parts per thousand currency sign5 cm distant from the anal verge (p = 0.14). Pathological complete response was achieved in 16 % of the patients in the pre-CRT group. The local recurrence rate (LRR) at 5 years was 5.7 % in the pre-CRT and 11.1 % in the post-CRT groups (p = 0.04). The distant recurrence rate (DRR) at 5 years was 76 % and 77 % in the pre-CRT and post-CRT groups, respectively (p = 0.1). Overall survival was similar in two groups (74.8 % vs. 75.3 %, p = 0.3). The treatment of stage T3, N0 rectal cancer patients with pre-CRT followed by surgery decreased LRR, but did not improve DRR or OS as compared with surgery followed by post-CRT in our patient cohort

Paraneoplastic pemphigus associated with fludarabine use

Paraneoplastic pemphigus is a severe mucocutaneous disease associated with B-cell lymphoproliferative disorders. A 51-yr-old man presented to the oncology clinic with mucocutaneous skin lesions after six cycles of fludarabine for non-Hodgkin's lymphoma. A punch biopsy from the skin showed suprabasal acantholysis and blister formation in the epidermis and upper dermis. Direct immunofluorescence demonstrated intercellular IgG deposition in all epidermal layers and complement (C3) at the basement membrane. The indirect immunofluorescence on rat bladder showed intercellular binding of IgG. These findings were consistent with paraneoplastic pemphigus associated with fludarabine use. The temporal association between fludarabine use and paraneoplastic pemphigus suggests there is an etiopathological link between these two entities

Male Breast Cancer: 37-Year Data Study at a Single Experience Center in Turkey

PURPOSE: The aim of this study is to evaluate the effects of prognostic factors on the overall survival (OS) and locoregional control (LC) among male breast cancer (MBC) patients treated at Cerrahpasa Medical School Hospital, along with a review of the related literature. METHODS: The data of 86 patients treated for MBC from 1973 to 2010 are retrospectively reviewed. Patient demographics and clinical information, including the date of diagnosis, treatment, clinical course, and the date and causes of death are routinely recorded. RESULTS: Median follow-up was 66 months. Isolated local-regional recurrence and distant metastases were observed in 15 (17.4%) and 24 (34.1%) of the cases, respectively. The 5-year OS rate was 65.8%; the disease-free survival rate was 72.4%, and the LC rate was 89.7%. The prognostic factors influencing local relapse were the T stage (p=0.002) and the chest wall muscular invasion (p=0.027) in the univariate analysis. The prognostic factors influencing OS were the presence of a positive axillary lymph node (p=0.001) and the T stage (p=0.001) in the univariate analysis. The T stage (p=0.008) and node (N) stage (p=0.038) were significant prognostic factors for OS in the multivariate analyses. Also, the T stage (p=0.034) was found to be significant for LC. CONCLUSION: We found that only the tumor size and lymph node status were independent prognostic factors for survival. In addition, only the tumor size was an independent prognostic factor for locoregional relapse. Modified radical mastectomy and conservative surgical procedures had similar outcomes for LC
