A total of 7251 histologically confirmed new cases of cancer (4117 males and 3134 females) were seen in the 6-year period 1979 to 1984 at the King Faisal Specialist Hospital and Research Centre in Riyadh, Saudi Arabia. The crude relative frequencies of cancer at various primary sites have been determined with reference to sex, age, geographic origin, and year of diagnosis. The most common cancer sites among males were non-Hodgkin's lymphomas, esophagus, lung, liver, stomach, and nasopharynx. Breast cancer was the most common tumor among the females, followed by non-Hodgkin's lymphomas and cancers of the thyroid, esophagus, cervix, and ovary. The most marked deviations were found in the Southern Region for cancers of the oral cavity (2.4 times higher), bladder (1.8 times higher), and lung (4.3 times lower). Known etiologic factors, such as local chewing, smoking habits, and schistosomiasis are likely to be responsible for these differences. Upward trends in cancers of lung, breast, colon and rectum, and the downward trend in esophageal cancer may reflect the rapid pace of modernization.

Based on own experience and on published data we report about indications and efficacy of endoscopic ultrasonography (EUS) in esophageal and gastric diseases. At the present time the following conclusions can be drawn: Submucous tumors can be clearly demonstrated and unequivocally distinguished from extramural compressions. Although the EUS aspect does not allow to differentiate benign from malignant lesions, EUS findings can give hints as to the nature of a submucous tumor (leiomyoma, lipoma, cyst). The main indication for EUS ist local tumor staging. The pT stage of esophageal carcinoma can be assessed correctly in 84% (73 to 92%) and that of gastric carcinoma in 80% (69 to 92%) of the cases by EUS. Especially in early tumor stages, EUS is superior to computed tomography. Regional lymph node metastases can be visualized in 70 to 90% of the cases. EUS is also helpful in the follow-up of patients with operative resection of esophageal cancer and in patients with gastric non-Hodgkin lymphoma during radio-/chemotherapy.

Esophageal cancer induced by radiation is uncommon. Irradiation of the head, the neck, the chest and the abdomen may cause an esophageal cancer several years later. Therefore, regular gastroscopy and biopsy of esophageal mucosa are strongly recommended in symptomatic patients. Surgery combined or not with radiotherapy seems to be the most effective treatment for this kind of cancer. We report a case of squamous cell carcinoma of the esophagus diagnosed 13 years after chemotherapy and radiotherapy for Hodgkin disease stade IIIb.

Mitoguazone (methylglyoxal bisguanylhydrazone, methyl-GAG or MGBG) is a synthetic polycarbonyl derivative with activity in patients with Hodgkin's and non-Hodgkin's lymphoma, head and neck cancer, prostate cancer, and esophageal cancer. Mitoguazone has also recently been documented to have activity in patients with AIDS-related lymphoma. Among anticancer drugs, mitoguazone has a unique mechanism of action via interference with the polyamine biosynthetic pathway. Polyamines stabilize DNA structure by non-covalent cross-bridging between phosphate groups on opposite strands. In addition, mitoguazone causes uncoupling of oxidative phosphorylation. In this study, the ability of mitoguazone to induce apoptosis by inhibiting the polyamine pathway was assessed in three Burkitt's lymphoma cell lines (Raji, Ramos and Daudi) and one prostate carcinoma cell line (MPC 3). Additional evaluations were performed in two human breast cancer cell lines (MCF7 with wild-type p53 and VM4K with mutated p53) to determine whether the p53 tumor suppressor gene was required for efficient apoptosis induction. The present study demonstrated that mitoguazone induces apoptosis in all the different human cancer cell lines tested in a concentration- and time-dependent way, and triggers a p53-independent programmed cell death in the human breast cancer MCF7 cell line.

The Epstein-Barr virus is an agent that causes African Burkitt's lymphoma, infectious mononucleosis, and Hodgkin's disease. It is also related to nasopharyngeal carcinoma and gastric carcinoma. The aim of this study was to evaluate the prevalence of the Epstein-Barr virus in esophageal cancer. Polymerase chain reaction and in situ hybridization were used to detect the Epstein-Barr virus. We detected 103 Epstein-Barr virus positive cells out of 107 of KYSE 273 cells using first standard-PCR. Epstein-Barr virus DNA could not be detected in 30 of the esophageal squamous cell carcinoma cell lines and 2 of the Barrett's esophageal adenocarcinoma cell lines. Out of 77 esophageal cancer patients, 3 cases were found positive for Epstein-Barr virus DNA using polymerase chain reaction. However, by in situ hybridization we found signals in only 1 of the 3 cases, the signal was located in the infiltrating lymphocytes. The Epstein-Barr virus is rarely associated with esophageal cancer.

Radiation therapy (RT) is commonly used to treat malignant tumors, but it leads to side effects and complications. Postradiation sarcomas developing from a previously irradiated area are especially vicious to deal with, though their occurrence is rare. This article focuses on the clinical manifestations, pathological characteristics, and therapeutic effects concerning postradiation soft tissue sarcomas (PRSTSs). A series of 14 PRSTSs treated between 1979 and 2000 in five hospitals in Japan were analyzed. Their histological types were malignant fibrous histiocytoma (eight cases), extraskeletal osteosarcoma (four cases), fibrosarcoma (one case), and leiomyosarcoma (one case). The primary diagnoses, RT history, latent period, and outcome of treatment were studied retrospectively. The original tumors included uterine cancer (seven cases), breast cancer (four cases), synovial sarcoma (one case), squamous cell carcinoma (one case), and Hodgkin's disease (one case). There were 13 women and 1 man, with ages ranging from 23 to 77 years (mean 58 years) at the time of the appearance of the PRSTS. RT doses ranged from 48 to 91 Gy (mean 62 Gy). The latent period from RT to the occurrence of the PRSTS varied from 4 to 27 years (mean 12.6 years). Altogether, 4 of 13 patients (31%) had recurrence of the sarcoma after resection. Of the 10 patients whose tumors were removed with a wide margin, one had a local recurrence; 3 cases were performed with a marginal margin and all 3 had a local recurrence. One of three who underwent RT and one of five who underwent chemotherapy (CT) responded. Of the 14 patients, 6 (42.9 %) survived continuously disease free, 2 (14.3%) died from other causes, 2 (14.3%) has an unknown outcome, and 4 (28.6 %) died of the disease during the follow-up period of 16-36 months (mean 24 months). The deaths due to other causes included an esophageal cancer and a wound infection. The prognosis of the PRSTS patients was not poor if the tumor could be removed with a wide surgical margin. Because adjuvant therapies including RT and CT had a poor effect on PRSTSs, the primary treatment of PRSTSs should be radical resection with a wide margin.

U.S. studies have reported an increased risk of esophageal and some other cancers in dry cleaners exposed to tetrachloroethylene. We investigated whether the U.S. findings could be reproduced in the Nordic countries using a series of case-control studies nested in cohorts of laundry and dry-cleaning workers identified from the 1970 censuses in Denmark, Norway, Sweden, and Finland. Dry-cleaning work in the Nordic countries during the period when tetrachloroethylene was the dominant solvent was not associated with an increased risk of esophageal cancer [rate ratio (RR) = 0.76; 95% confidence interval (CI), 0.34-1.69], but our study was hampered by some unclassifiable cases. The risks of cancer of the gastric cardia, liver, pancreas, and kidney and non-Hodgkin lymphoma were not significantly increased. Assistants in dry-cleaning shops had a borderline significant excess risk of cervical cancer not found in women directly involved in dry cleaning. We found an excess risk of bladder cancer (RR = 1.44; 95% CI, 1.07-1.93) not associated with length of employment. The finding of no excess risk of esophageal cancer in Nordic dry cleaners differs from U.S. findings. Chance, differences in level of exposure to tetrachloroethylene, and confounding may explain the findings. The overall evidence on bladder cancer in dry cleaners is equivocal.

Cervical cancer is caused by a combination of environmental and genetic risk factors. Infection by oncogenic types of human papillomavirus is recognized as the major environmental risk factor and epidemiological studies indicate that host genetic factors predispose to disease development. A number of genetic susceptibility factors have been proposed, but with exception of the human leukocyte antigen CHLA, class II, have not shown consistent results among studies. We have performed the first genomewide linkage scan using 278 affected sib-pairs to identify loci involved in susceptibility to cervical cancer. A two-step qualitative non-parametric linkage analysis using 387 microsatellites with an average spacing of 10.5 cM revealed excess allelic sharing at nine regions on eight chromosomes. These regions were further analysed with 125 markers to increase the map density to 1.28 cM. Nominal significant linkage was found for three of the nine loci [9q32 (maximum lod-score, MLS) =1.95, P<0.002), 12q24 (MLS=1.25, P<0.015) and 16q24 (MLS=1.35, P<0.012)]. These three regions have previously been connected to human cancers that share characteristics with cervical carcinoma, such as esophageal cancer and Hodgkin's lymphoma. A number of candidate genes involved in defence against viral infections, immune response and tumour suppression are found in these regions. One such gene is the thymic stromal co-transporter (TSCOT). Analyses of TSCOT single nucleotide polymorphisms further strengthen the linkage to this region (MLS=2.40, P<0.001). We propose that the 9q32 region contains susceptibility locus for cervical cancer and that TSCOT is a candidate gene potentially involved in the genetic predisposition to this disease.

Chemoradiotherapy improves therapeutic outcome in many different types of cancer. However, there is concern about the occurrence of delayed complications, as patients are surviving longer. Because patients with esophageal cancer receive a wide range of irradiation field to the mediastinum and the heart, they may have delayed complications of heart and lung functions as previously reported in Hodgkin's disease. We presented a case of death related to uncontrollable pleural and pericardial effusions in a patient with advanced cancers of the esophagus and stomach who achieved a complete remission following chemoradiotherapy and salvage gastric resection, focusing on detailed pathophysiological conditions related to concurrent chemoradiotherapy.

The main aim of this study was to assess the burden of cancer disease in residents of Vercelli (northern Italy), by analysing mortality data and hospital discharge forms. This was done in order to verify whether, as widely suspected among the city's population, an increased risk of cancer exists in the area, due to the large number of existing agricultural and industrial activities. Tumour mortality rates were compared with mortality data from the tumour registries of the province of Biella and of the city of Turin to identify a possible excess number of cases in Vercelli.An increased mortality rate was observed with respect to reference values (mortality registry of the city of Turin) for several tumours; more specifically results revealed a significantly increased mortality rate due to colorectal tumours, leukemias and nervous system tumours in both genders. Excess mortality was detected in males but not in females for esophageal cancer, non melanoma skin cancers, pancreatic, laryngeal, prostatic, renal and bone cancers. Conversely, in females, the standard mortality ratios (SMR) were found to be statistically significant for renal and laryngeal cancers and for Hodgkin's lymphoma.
