The Saudi Cancer Registry reported in 2007 the 5-year observed survival for the most common cancer sites for the years 1994–2004. In this report we looked at the cancer survival in the period 2005–2009 and evaluated the trend over the 15 years period from 1994 to 2009. Cases of the top 14 cancer sites reported by the population based Saudi Cancer Registry from 1 January 2005 to December 31, 2009, were submitted for survival analysis. The vital status of those patients was collected. Analysis of survival for the above period was compared with the prior reported 2 periods (1994–1999, 2000–2004). In addition, analysis was done according to age, sex, disease stage and the province. Data of 25,969 patients of the commonest cancer sites were submitted. Of those 14,146 patients (54%) had complete demographic data available and vital status was reported. Thyroid cancer had the highest 5- year observed survival of 94% (95% confidence interval (CI) 93–95%)), followed by Breast (72%, 95% CI 71–74%). In hematological malignancies, Hodgkin’s Lymphoma had the highest 5-year survival of 86% (95% CI 84–88%). Survival rates has improved in most of the cancers sites for the studied periods except for lung, uterine and Hodgkin’s lymphoma which plateaued. Our study confirms a steady improvement in the 5-year observed survival over time for the majority of cancers. Our survival data were comparable to western countries. This data should be used by policy makers to improve on cancer care in the kingdom.
Pseudomyogenic hemangioendothelioma (PHE) also known as epithelioid sarcoma-like hemangioendothelioma (ES-H) is a vascular lesion of intermediate grade biologically behaving between benign hemangioma and malignant angiosarcoma. We present a 35-year-old male with an unremarkable medical history, who was referred to a sarcoma clinic complaining of right heel pain with equinus deformity and a mass in his right lower limb for 6 months. Biopsy was performed and reported as Pseudomyogenic Hemangioendothelioma. The patient was started on pazopanib with a favorable clinical and radiological response. Long-term follow-up is still needed, however further studies are vital to clarify the role of Tyrosine Kinase Inhibitor therapy.
e16277 Background: Small bowel adenocarcinoma (SBA) is a rare disease. We aim to describe patient's characteristics and clinical outcomes among Saudi patients. Methods: All patients with SBA diagnosed between 2007 - 2020 were reviewed. Logistic regression was used to assess variables associated with metastasis at diagnosis, and a log-rank test was used to compare factors associated with survival. Results: Forty-three patients were eligible for analysis, and (76.7%) were males. The median age at diagnosis was 53 years. History was significant for colon cancer in two patients, celiac disease in three patients, Lynch syndrome, Familial adenomatous polyposis (FAP), Non-APC in one patient, and cholecystectomy in seven patients. The common initial presenting symptoms were abdominal pain (58.8%), bowel obstruction (30.2%), Overt gastrointestinal bleeding (9.3%). Tumor markers were elevated in 21 patients. EGD was used for diagnosis in 60.5%, while CT scan in 23.3%. The most common primary site was duodenum 60.5%, jejunum 27.9%, ilium 7%. Stage IV was (41.9%). The most common site for metastases was the liver in 10 patients. Patients' ECOG performance status was 0/1 in 51% at diagnosis. Univariate analysis did not reveal that patients with high Neutrophil-lymphocyte Ratio (NLR) (≥0.85) are more likely to be metastatic; P = 009. There was no association of sex, presenting complaints, tumor markers with the stage at diagnosis. Surgery was performed for 53.4% of patients (RO, 73%), and the median DFS was 49 vs. 8 months in R0 vs. R1 group, respectively (p = 0.01). FOLFOX Chemotherapy regimen was given for 10 patients as adjuvant treatment and for 8 patients for metastatic sitting. The median duration of follow-up was 12 months. The median overall survival (OS) for localized stages was not reached, and for the metastatic stage was 10 months. The 3 years OS based on stages were 100% (I), 85% (II), 53% (III) and 35% for (IV), p = 0.001. Other factors associated with survival were ECOG Performance status (p < 0.001), NLR ( < 0.001), CA19-9 (p = 0.04), and receiving chemotherapy in a metastatic setting (p = 0.02). Conclusions: SBA is diagnosed at a younger age in Saudi patients and more in males. The advanced stage, lower performance status score, high CA19-9, and high NLR at diagnosis are associated with poor OS. NLR could be a prognostic factor for a metastatic stage at diagnosis.
Background Gastroenteropancreatic Neuroendocrine tumors (GEP-NET) are rare neoplasms with limited reported data from the Middle East. Our study aims to report the clinicopathological feature, treatment patterns, and survival outcomes of patients with GEP-NET from our part of the world. Methods Medical records of patients diagnosed with GEP-NET between January 2011 and December 2016 at a single center in Saudi Arabia were reviewed retrospectively, and complete clinicopathological and treatment data were collected. Patients’ survival was estimated by the Kaplan–Meier method. Results A total of 72 patients were identified with a median age of 51 years (range 27–82) and male-to-female ratio of (1.1). The most common tumor location was the pancreas (29.1%), followed by small bowel (25%), stomach (12.5%), rectum (8.3%), colon (8.3%), and appendix (6.9%). Forty-one patients (57%) had well-differentiated grade (G)1, 21 (29%) had G2, and 4 (6%) had G3. In five patients, the pathology was neuroendocrine carcinoma and in one it could not be classified. 54.2% of the patients were metastatic at diagnosis. Forty-two patients underwent surgical resection as primary management while 26 underwent systemic therapy, three patients were put on active surveillance, and one was treated endoscopically with polypectomy. The 5-year overall survival and progression-free survivals were 77.2% and 49%, respectively, for the whole group. Patients with G1 and 2 disease, lower Ki-67 index, and surgically treated as primary management had significantly better survival outcomes. Conclusion Our study suggests that the most common tumor locations are similar to western reported data. However, there seems to be a higher incidence of metastatic disease at presentation than in the rest of the world.
Background: The relationship between cancers and thromboembolic events is well established. In our study we aim to determine the burden of thromboembolic events in patients with solid tumors and identify the risk factors related to their development.Methods: Data on patients with solid tumors and thromboembolism between January 2013 and September 2014 were collected and analyzed. Results: During the studied period 174 patients were identified, 172 (98.9%) of which had venous thrombus embolism. 137 (79%) were diagnosed with deep vein thromboses and 67 (38.5%) with pulmonary embolisms. 84 (48.3%) were symptomatic and 90 (51.7) were incidental at diagnosis. The most common risk factors were female sex, high Body mass index, metastatic stage, colorectal and breast primaries, and anti-neoplastic therapy.Conclusion: Our study confirmed the high burden of thromboembolic events in cancer patients and the relevant risk factors associated with its development.
