ABSTRACT
Peritoneal surface malignancies (PSM) are aggressive and associated with poor prognosis. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) have been used to treat PSM since 1990. In Saudi Arabia, the first HIPEC and pressurized intraperitoneal aerosol chemotherapy (PIPAC) were performed in 2008 and 2019, respectively. With increasing incidences of PSM in Saudi Arabia, the demand for such procedures has grown. This article outlines the status of PSM management in Saudi Arabia and its prospects.
ABSTRACT
In Saudi Arabia, gastric cancer is a major health burden, ranking as the thirteenth most common cancer type. Situs inversus totalis (SIT), which is a very rare congenital anomaly, refers to a completely reversed location of the abdominal and thoracic organs (mirror image of the normal). Here, we present the first reported case of gastric cancer in an SIT patient in Saudi Arabia and the Gulf Cooperation Council (GCC) countries, and highlight the challenges faced by the surgical team in the removal of such cancer in this patient population.
ABSTRACT
BACKGROUND: There is paucity in the literature regarding gallbladder cancer in Saudi Arabia, possibly because it is not among the top 10 cancers diagnosed nationwide according to the Saudi Cancer Registry. Moreover, national or regional data on gallbladder cancer in Saudi Arabia have not been analyzed. The purpose of this study was to describe the presentation, disease stage, histology, and survival rates for gallbladder cancer in Saudi patients at a single institution between January 1, 2010 and December 31, 2017. MATERIALS AND METHODS: This was a retrospective study of 76 patients who presented to our hospital between January 1, 2010 and December 31, 2017, with established diagnosis of gallbladder carcinoma. The diagnosis was made either histopathologically following simple laparoscopic cholecystectomy or biopsy from metastatic liver lesion in patients with gallbladder mass, or the high suspicion of gallbladder carcinoma based on incidental radiological findings. Presentation, disease stage, histology, and treatment modalities were analyzed using descriptive statistics and frequency distributions. Survival rates were analyzed and presented using Kaplan-Meier curves. RESULTS: Based on initial analyses the disease was more frequent among women (62.0%) than men (39.0%). Surgical resection was attempted in 40.8% patients. The average age at presentation and diagnosis of gallbladder carcinoma was 62.4 years. The disease had two peaks, one at 51.0 years and the other between 66.0 and 70.0 years. The median survival time for the overall at-risk patients was only 1.0 year, while for stage IVB patients was 7.2 months. Adenocarcinoma not otherwise specified (NOS) was the most common histopathology type (75.0%), with most patients presenting with stage IVB disease (75.0%). Gallbladder carcinoma was incidentally detected in 42.1%, including three cases (3.9%) diagnosed at our hospital. CONCLUSIONS: Gallbladder cancer is a rare type of cancer in Saudi Arabia, and most patients are treated surgically, despite being mostly diagnosed at the advanced stage of the disease.
ABSTRACT
Mucinous cystic neoplasms (MCN) of the pancreas can vary from benign to premalignant and malignant. Preoperative diagnosis is essential to offer the patient appropriate treatment. Occasionally these cases may harbor anaplastic carcinoma while clinically masquerade as a pseudocyst. Here in, we report an unusual case of a 37-year old female presented with recurrent abdominal pain that was suspected clinically and by imaging studies to have a pseudocyst. EUS-FNA with internal drainage of the cyst was performed. Cytological evaluation of the cyst fluid showed numerous inflammatory cells composed mainly of many neutrophils admixed with macrophages reminiscent of the usual pseudocyst content but there were scattered rare dyscohesive malignant cells which were highly pleomorphic with multinucleation. Immunostains on the cell block showed immunoreactivity of these cells including the multinucleated cells for Cam 5.2 and AE1/AE3 and focally for Ber-Ep4, Moc -31, and CA19-9. The subsequent resection confirmed the presence of anaplastic (undifferentiated) carcinoma (AC) arising in a MCN of the pancreas. Diagn. Cytopathol. 2016;44:538-542. © 2016 Wiley Periodicals, Inc.
