Treatment of the adenocarcinoma of the esophagogastric junction at a single institution in Mexico.
ABSTRACT Adenocarcinoma of the esophagogastric junction (EGJ) is rapidly increasing in the west. Our aim is to define the prognostic factors and treatment of EGJ carcinoma in Mexico, particularly the location after the Siewert's classification.
A retrospective cohort of patients suffering from EGJ adenocarcinoma treated from 1987 to 2000. The Kaplan-Meier and the Cox's models were used to define prognostic factors.
Two hundred and thirty-four patients were included, 90 females and 144 males. Surgical resection was possible in 68 cases only (29%). Significant prognostic factors were tumor node metastasis (TNM) stage [stages I-II: risk ratio (RR) is 1; stage III RR is 1.3, 95% confidence interval (CI) 0.75-2.4; stage IV RR, 2.04, 95% CI 1.1-3.7], gender (male RR = 1.47, 95% CI 1.05-2.05), metastatic lymph node ratio (no resection: RR = 1; ratio 0.2-1 RR=0.67, 95% CI 0.39-1.14; ratio 0-0.19 RR = 0.42, 95% CI 0.23-0.76) and seralbumin (3 mg/dL or less RR = 2.05 95% CI 1.3-3.2; 3.1-3.4 mg/dL RR = 1.9 95% CI 1.2-3.03; 3.5-3.8 mg/dL RR = 1.3 95% CI 0.8-1.9; 3.9 mg/dL or more: RR = 1) (model P = 0.0001).
EGJ adenocarcinoma is a highly lethal neoplasia and the location after the Siewert' classification is not a prognostic factor. In Mexico, TNM clinical stage, serum albumin, gender, surgical resection and metastatic lymph node ratio are significant prognostic factors. Curative treatment is infrequent but radical resection is associated to longer survival. Consequently, the management must consider quality of life and surgical morbidity.

ABSTRACT: Accurate outcome prediction in gastroesophageal malignancies is challenging. Acute-phase response proteins (APRPs) have been claimed to be independent prognosticators, although the basis for their association with prognosis remains unexplained. We hypothesized that, similarly to pancreatic and lung cancers, changes in APRPs in gastroesophageal malignancies are associated with cachexia and accelerated angiogenesis. C-reactive protein (CRP), albumin and transferrin serum levels were evaluated and the Glasgow Prognostic Score (GPS) calculated. These data were compared with concentrations of circulating interleukin (IL)-1, IL-6 and IL-8, tumor necrosis factor-alpha (TNF-alpha), vascular endothelial growth factor (VEGF)-A, VEGF-C and midkine in 96 gastroesophageal cancer patients (49 with cachexia) and 42 healthy subjects. Results: Albumin and CRP levels were altered in the cancer patients, with further CRP elevation in those with cachexia. Transferrin was decreased only in the cachectic patients. The interrelationships between the APRPs were strengthened in cachexia and only then were APRPs correlated with the cytokines elevated in gastroesophageal cancer-related cachexia: IL-6, IL-8, VEGF-A and midkine. GPS corresponded well to transferrin, IL-1, IL-6, IL-8, TNF-alpha, VEGF-A and midkine concentrations. Cachexia in gastroesophageal cancers is associated with changes in APRP concentrations. This, together with a direct relationship of APRPs with accelerated angiogenesis, may constitute a foundation for the association of APRPs and GPS with outcome in these malignancies.Clinical Chemistry and Laboratory Medicine 02/2008; 46(3):359-64. · 3.01 Impact Factor

ABSTRACT: Quality of life questionnaires (QLQ) QLQ-STO22 and QLQ-OES18 are currently available to measure Health-related quality of life (HRQL) in patients with Esophageal (EC) or Gastric cancer (GC). The QLQ-OG25 integrates questions from both questionnaires to be useful for EC, Esophagogastric junction carcinoma (EGJC), and GC. Our aim was to validate the Mexican-Spanish version. The translation procedure followed European Organization for Research and Treatment of Cancer (EORTC) guidelines. QLQ-C30 and QLQ-OG25 instruments were completed by patients with EC, EGJC, and GC. Patients were divided into three groups: (1) palliative treatment; (2) treatment with curative intent, and (3) survivors. Reliability and validity tests were performed. One-hundred sixty-three patients were included: 62 women and 101 men (mean age, 54.9 years; range, 22-82 years). Sixty-nine, seventy-three, and twenty-one patients were allocated into groups 1, 2, and 3, respectively. Questionnaire compliance rates were high and were well accepted. Group 3 patients reported better functional HRQL scores and lower symptom scores than patients in groups 2 and 1. Scales in the QLQ-C30 and QLQ-OG25 distinguished among other clinically distinct groups of patients. Cronbach's α coefficients of all multi-item scales of the QLQ-OG25 instrument were >0.7 (range, 0.7-0.83). Multitrait scaling analysis demonstrated good convergent and discriminant validity, even adjusting by location. Test-retest scores were consistent. The Mexican-Spanish version of the EORTC QLQ-OG25 questionnaire is reliable and valid for HRQL measurement in patients with esophagogastric cancer and can be used in clinical trials in the Mexican community.Psycho-Oncology 05/2011; 21(7):745-53. · 3.51 Impact Factor

ABSTRACT: The incidence of adenocarcinoma of the esophagogastric junction (AEG) has been increasing in Western countries. It is unclear, however, whether similar changes are occurring in Asia. We therefore investigated the incidence of AEG in Korea, and assessed the clinical characteristics of three types of AEG based on Siewert's classification. We retrospectively reviewed the medical records of 16 811 patients diagnosed with esophageal squamous cell carcinoma (ESC, n= 1450) or gastric noncardiac adenocarcinoma (GNCA, n= 14 751) between 1992 and 2006. The patients were divided into three 5-year cohorts (cohort A [1992-1996], n= 2734, cohort B [1997-2001], n= 5727, and cohort C [2002-2006], n= 8350), and the ratios of AEG (n= 610) to non-AEG (ESC and GNCA) in each cohort were compared. Using Siewert's classification, the tumors were categorized into one of three types, and patient demographic features and 5-year survival rates were compared. The ratio of AEG to non-AEG cases did not change over time (0.037, 0.034, and 0.039 for cohorts A, B, and C, respectively; P= 0.40). Of the 610 patients with AEG, 23 (3.7%) had type 1 tumors, 47 (7.7%) had type 2, and 540 (88.5%) had type 3. The 5-year survival rate of patients with type 1 AEG was much lower (4.8 +/- 4.7%) than that of those with type 2 (47.9 +/- 7.8%) and type 3 (47.4 +/- 2.5%) tumors. Unlike in Western countries, the ratio of AEG to non-AEG cases has not increased over time in Korea. Type 1 AEG was rarer and associated with a more unfavorable prognosis in Korea than in Western countries.Diseases of the Esophagus 03/2009; 22(8):676-81. · 1.64 Impact Factor
