Pattern of Malignant Tumors in Najran, Saudi Arabia: A 5-year Retrospective Study

Background: The relative frequency of malignant tumors has been reported to have an association with age, gender, and location. The current study is a retrospective study to assess the pattern and relative frequency of different malignant tumors in Najran, Saudi Arabia. Methods and Results: All patients from both genders were included in the study from June 2014 to May 2019, and data were retrieved from the records of confirmed cancer cases at the departments of pathology. For 5 years, a total of 763 cases [325(42.6%) men and 438(57.4%) women] and 37 types of malignant tumors were diagnosed in Najran. According to the histopathological diagnosis, carcinomas were the most frequent tumors (n=564, 73.9%). According to the affected organ/body system, tumors of the gastrointestinal system were the commonest malignancy, observed in 156 (20.4%) of the patients (91 men and 65 women). Finally, the chi-square test revealed that the frequency of malignant tumors climbed as age increased (P=0.0005). Conclusion: The relative frequency of several cancers in Najran showed that the most common cancers in both genders are in the following order: gastrointestinal, thyroid, breast, skin and soft tissue cancers, and lymphoma. In addition, women are more affected than men, and increasing age is a risk factor to develop a malignancy.

(E)US-Elastografie: Heutiger Stand und Perspektiven

(Endo)sonographic real-time elastography is a new method to describe the mechanical properties of tissue. Similar to colour flow Doppler ultrasonography, a region of interest is defined. The relative stiffness of the tissues within this area is described by colours superimposing on the B-mode image. Real-time elastography can be performed with linear scanners for transcutaneous use, rigid endocavitary probes and with flexible echoendoscopes. The probes can be used to compress the tissue. The elasticity modulus is calculated from the resulting deformation of the tissue. In endoscopic ultrasound, arterial and cardiac pulsations or respiratory movements cause the deformation of the tissue that is used for the calculation. Several studies have demonstrated that real-time elastography is feasible and improves the diagnostic accuracy for tumours of the breast, the prostate, the cervix, and the thyroid gland. Endosonographic elastography has been employed in the examination of lymph nodes and the pancreas. For the differentation between benign and malignant lymph nodes, the accuracy is reported to be 85 % to 90 %. Therefore, the method seems to be useful to select lymph nodes suitable for biopsy. The elastographic pattern of malignant tumours of the pancreas is different from that of the normal pancreas, but similar to that of chronic pancreatitis due to the same biomechanical architecture. Therefore, the early diagnosis of cancer within chronic pancreatitis will probably not be improved by elastography. In summary, (endo)sonographic real-time elastography is a promising new method. Nevertheless, prospective studies are needed to define useful applications and the clinical significance of the method.

Mortality from Malignant Diseases in a Saudi Population in the Asir Region: A Four-Year Review

The aim of this study was to determine the causes of mortality from different malignancies in the Asir region of Saudi Arabia. The Asir region is an area of about 80,000 km 2 , with a population of about 1.2 million people. 1 Asir Central Hospital is the main referral hospital, and serves as the teaching hospital of the medical school in the region. All complicated and terminal cases from the 17 hospitals in the region are routinely referred to this hospital. As such, deaths from malignant conditions at the hospital provide a fair reflection of such deaths in this area. We decided, therefore, to study the causes of death from malignant conditions in a four-year period so as to identify the main malignant killers in the region.

Cancer at King Khalid University Hospital, Riyadh

This study is based on data collected from a total of 1196 patients (725 males and 471 females) with histologically confirmed cancer seen in King Khalid University Hospital over a 5-year period between September 1985 to August 1990. Four hundred forty-five patients were non-Saudi (37.20%). The relative frequency and rank of order are determined for various cancers in Saudi patients and total group and compared with the results of the other published studies on cancer epidemiology in Saudi Arabia. The most common cancers among Saudi males were liver, non-Hodgkin's lymphomas, stomach, lung, central nervous system, prostate, lymphoid, leukemias, myeloid leukemias, urinary bladder and Hodgkin's lymphomas, central nervous cancers among Saudi females were breast, thyroid, non-Hodgkin's lymphomas, central nervous system, stomach, myeloid leukemias, esophagus, lymphoid leukemias, liver and ovary. Rank order and relative frequency for liver cancer in both sexes is the highest among any study previously published on the epidemiology of cancer in Saudi Arabia.

Pattern of Cancer at Asir Central Hospital, Abha, Saudi Arabia

Six hundred ninety-seven histologically confirmed cases of cancer were seen in the three-year period, 1987 to 1989, at Asir Central Hospital in Abha, Saudi Arabia. Percentage (crude relative) frequencies of cancer at various sites were determined. The most common cancer sites among males were skin, liver, lymphoid tissue (i.e., non-Hodgkin's lymphomas), bladder,, blood (leukemias), stomach, colon, esophagus, central nervous system, and prostate. Skin cancer was also the most common cancer among females, followed by breast, lymphoid tissue (non-Hodgkin's lymphomas), blood (leukemias), thyroid, stomach, colon, oral cavity, esophagus, and cervix.
