Background: Self-expanding metallic stents (SEMS) insertion is an alternative to emergency surgery in malignant colonic obstruction. However, the long-term oncological outcome of stents as a bridge to surgery is limited and controversial.

Objectives: To determine the long-term oncological outcome of stents as a bridge to surgery.

Methods: Data of patients who underwent emergency surgery and endoscopic stent insertion as a bridge to surgery due to obstructing colon cancer at Soroka Medical Center during a 14 year period were collected retrospectively. Preoperative data, tumor staging, and oncological outcomes in terms of local recurrence, metastatic spread, and overall survival of the patients were compared.

Results: Sixty-four patients (56% female, mean age 72 years) were included in the study: 43 (67%) following emergency surgery, 21 stent inserted prior to surgery. A stent was inserted within 24–48 hours of hospital admission. The mean time between SEMS insertion and surgery was 15 days (range 0–30). Most of the patients had stage II (41%) and stage III (34%) colonic cancer. There was no difference in tumor staging and localization between groups. There was no significant difference in disease recurrence between SEMS and surgery groups, 24% and 32%, respectively. Disease-free survival rates were similar between the SEMS group (23.8%) and surgery group (22%). Four year and overall survival rates were 52.4% vs. 47.6%, 33.3% vs. 39.5%, respectively.

Conclusions: SEMS as a bridge to surgery in patients with obstructing colon cancer provide an equivalent long-term oncological outcome to surgery alone.

Autoinflammatory and autoimmune disorders are characterized by chronic activation of the immune system, which leads to systemic self-directed inflammation in genetically predisposed individuals. Mutations in inflammasome-related proteins have been associated with autoinflammatory disorders, and the link between inflammasome and autoimmune disorders is becoming increasingly clear. As researchers learn more about these two areas, other disorders that were once thought to be autoimmune are now being considered autoinflammatory, or as having at least an autoinflammatory component. This review depicts the role of interleukin-1 as “Ariadne’s thread” on the path through the labyrinth of autoinflammatory and autoimmune disorders and emphasizes the blurred boundary between innate and adaptive immune systems.

Background: Hodgkin’s lymphoma is a distinct primary solid tumor of the immune system that shows wide variation in incidence among different geographic regions and among various races. It was previously suggested that susceptible people living in certain parts of Israel had a higher risk of HL[1] because of exposure to unidentified environmental factors in these regions. Compared with other parts of Israel, these regions were characterized by a higher proportion of Israeli-born Jews.

Objectives: To study time trends in the incidence rate of HL in Israeli-born Jews of all age groups during the years 1960–2005.

Results: A total of 4812 Jewish cases of HL were reported to the Israel Cancer Registry during the study period 1960–2005. There has been a persistent increase in the age-standardized incidence rate of HL, all subtypes pooled, in Israeli-born Jews in both men and women. The age distribution pattern in both genders was bimodal in all periods. The highest incidence was observed in the 20–24 year age group: for women (9.13 per 100,000 per year) during the period 1988–1996, and for men (6.60 per 100,000 per year) during the period 1997–2005.

Conclusions: The reported incidence level of HL in Israeli-born young adult Jews in Israel has increased in recent years to high levels compared with other western countries. Our findings suggest a cohort effect to unidentified factors affecting Israeli-born young adult Jews in Israel.

Background: Disseminated intravascular coagulation associated with malignant bone marrow involvement has been described as a rare complication of gastric carcinoma and most patients die within 1–4 weeks. Effective chemotherapy of the underlying malignancy may be the only way to control acute DIC[1].

Objectives: To assess the benefit of infusional 5-fluorouracil as the primary treatment of metastatic gastric carcinoma and DIC at diagnosis.

Methods: From February 2001 to January 2005, six women (median age 48 years) with gastric carcinoma who presented with diffuse bone metastases and acute DIC were treated in our department. Diagnosis was based on primary gastric and bone marrow biopsies. DIC was confirmed by laboratory findings. Initial treatment consisted of infusional 5FU[2] 200 mg/m2/day. When the bleeding tendency stopped, cisplatin 60 mg/m2 and epirubicin 50 mg/m2 given every 3 weeks were added.

Results: Within one week of starting the treatment, the clinical and laboratory signs of acute DIC were resolved in five of six patients. Upon clinical improvement, five patients subsequently received epirubicin and cisplatin. Survival, however, was short (mean 15 weeks). All patients died with symptoms of bleeding, showing clinical and laboratory signs of DIC.

Conclusions: Based on our experience, infusional 5FU is an effective regimen with negligible myelosuppression; thus, it may be a good choice as initial therapy for this group of patients. The response induced by protracted 5FU was usually short and lasted for a few weeks only. Therefore, once DIC symptoms are controlled, the addition of newer cytotoxic drugs may be necessary to consolidate the remission.

 Background: Exposure to asbestos is the main established cause of mesothelioma; the incidence of this tumor is thus often interpreted as an index of past exposure. Asbestos has been widely used in Israel in industry and building, exposing certain population groups to the risk of developing mesothelioma.

Objectives: To analyze the incidence of mesothelioma in Israel during the years 1960-96, and to project its trend for the following years.

Methods: We conducted a population-based study of the incidence of mesothelioma reported to the Israel Cancer Registry during 1960-96. Time trends were analyzed from data on the annual import of asbestos to Israel, which may indicate the magnitude of past exposure. Based on these findings, trends in the incidence of mesothelioma in Israel were projected for the subsequent years.

Results: A total of 327 cases of mesothelioma were reported to the Israel Cancer Registry during the study period. The incidence in Jews was higher than in Arabs (age-standardized incidence rate 2.64 vs. 1.35 per million/year, respectively). Among the Jewish population, Israeli-born males and males born in Europe and America showed the highest incidence (ASR 4.23 and 4.15 per million/year, respectively). Israeli-born males were 20 years younger than Jewish males born elsewhere. The incidence was twice as high among males than females and increased sevenfold from its nadir (1.17 per million/year) in 1978--80 to its peak (8.5 per million/year) in 1993-96. During a similar period the incidence among females increased from 0.33 to 2.56 per million/year. The incidence in both sexes does not appear to level off. The large wave of immigration from the former Soviet Union that began in 1989 only partly accounts for the increased incidence in 1993-96. The time trend in the incidence of mesothelioma in both sexes parallels the use of asbestos in Israel, which peaked in the years 1976-78.

Conclusions: The incidence of mesothelioma in Israel has increased sharply in recent years, unrelated to a wave of immigration from East Europe, and is predicted to continue to rise for another 10-15 years.

Background: A previous study on Hodgkin's lymphoma in southern Israel found that Bedouin patients had an increased rate of Epstein-Barr virus expression in their tumor cells.

Objectives: To determine the influence of the patients' communities on the pattern of disease in HL.

Methods: We compared the clinical features, demographic data, stage at diagnosis, treatment modality and outcome, as well as laboratory findings, in four community-based subgroups. These groups comprised kibbutz residents (n=11), Bedouin (n=19), new immigrants from the former USSR (n=22), and town-dwellers (n=82).

Results: The Bedouin patients differed significantly from the new immigrants and town-dwellers, particularly regarding the rate of EBV sequences in the tumor tissues, and a poorer response to treatment. The kibbutz patients did not differ significantly from the other populations regarding most of the parameters studied, but showed an intermediate expression of EBV antigens compared to Bedouin patients and the rest of the cohort.

Conclusions: This study indicates that HL may behave differently in different population groups in a given geographic area. Notably, the Bedouin patients showed markedly different clinical and biological patterns of this malignancy.
