Abstract
Chronic Myeloid Leukemia (CML) is characterized by chromosomal aberrations involving the fusion of the BCR and ABL genes on chromosome 22, resulting from a reciprocal translocation between chromosomes 9 and 22. This fusion gives rise to the oncogenic BCR-ABL, an aberrant tyrosine kinase identified as Abl protein. The Abl protein intricately regulates the cell cycle by phosphorylating protein tyrosine residues through diverse signaling pathways. In CML, the BCR-ABL fusion protein disrupts the first exon of Abl, leading to sustained activation of tyrosine kinase and resistance to deactivation mechanisms. Pharmacological interventions, such as imatinib, effectively target BCR-ABL's tyrosine kinase activity by binding near the active site, disrupting ATP binding, and inhibiting downstream protein phosphorylation. Nevertheless, the emergence of resistance, often attributed to cap structure mutations, poses a challenge to imatinib efficacy. Current research endeavours are directed towards overcoming resistance and investigating innovative therapeutic strategies. This article offers a comprehensive analysis of the structural attributes of BCR-ABL, emphasizing its pivotal role as a biomarker and therapeutic target in CML. It underscores the imperative for ongoing research to refine treatment modalities and enhance overall outcomes in managing CML.

Abstract
Background and Objectives: Prognostic biomarkers in prostate cancer (PCa) include PTEN, ERG, SPINK1, and TFF3. Their relationships and patterns of expression in PCa in developing countries, including Jordan, have not yet been investigated. Materials and Methods: A tissue microarray (TMA) of PCa patients was taken from paraffin-embedded tissue blocks for 130 patients. PTEN, ERG, SPINK1, and TFF3 expression profiles were examined using immunohistochemistry (IHC) and correlated with each other and other clinicopathological factors. Results: PTEN loss of any degree was observed in 42.9% of PCa cases. ERG and TFF3 were expressed in 59.3% and 46.5% of PCa cases, respectively. SPINK1 expression was observed in 6 out of 104 PCa cases (5.4%). Among all PCa cases (n = 104), 3.8% (n = 4) showed SPINK1+/ERG+ phenotype, 1.9% (n = 2) showed SPINK1+/ERG- phenotype, 56.7% (n = 59) showed SPINK1-/ERG+ phenotype, and 37.5% showed SPINK1-/ERG- phenotype (n = 39). Among ERG positive cases (n = 63), 6.3% were SPINK1 positive. Among SPINK1 positive cases (n = 6), 66.7% were ERG positive. SPINK1 expression was predominantly observed in a subgroup of cancers that expressed TFF3 (6/6). Additionally, a statistically significant loss of PTEN expression was observed from Gleason Score 6 (GS6) (Grade Group 1 (GG1)) to GS9-10 (GG5); (p-value 0.019). Conclusions: This is the first study to look at the status of the PTEN, ERG, SPINK1, and TFF3 genes in a Jordanian Arab population. Loss of PTEN has been linked to more aggressive prostate cancer with high GSs/GGs. SPINK1 expression was predominantly observed in a subgroup of cancers that expressed TFF3. Our results call for screening these biomarkers for grading and molecular subtyping of the disease.

Abstract
PURPOSE Existing prognostic biomarkers are inadequate for stratifying breast cancer patients with the highest risk of tumor progression at the time of diagnosis. Here, we demonstrate that the small GTPase Ran has predictive value for breast cancer (BC) patients as a whole, and for specific BC subtypes. PATIENTS AND METHODS Ran expression was quantified by immunohistochemistry in 263 patients with primary breast cancer diagnosed at the Breast Unit, Royal Liverpool Hospital. Additionally as an independent validation, we also analyzed the mRNA expressions of Ran, ER, PR, and Cerb-2, the triple-negative endocrine receptors, and their associations with patient survival in a combined patient cohorts of multiple public datasets (n = 1079). We analyzed the data with Spearman's rank correlation and Kaplan-Meier plots coupled with Wilcoxon-Gehan tests, respectively. All statistical tests were two-sided. RESULTS Ran nuclear, cytoplasmic, and total staining are substantially associated with poor survival, independent of conventional prognostic markers such as estrogen receptor (ER), human epidermal growth factor receptor 2 (HER2), and lymph node status. According to the datasets, Ran was significantly correlated with distant metastasis-free survival (DMFS) and relapse-free survival (RFS). CONCLUSION We found that Ran expression is a unique predictive biomarker for patient survival, metastasis, and tumor relapse. This biomarker could be used for diagnostic purposes, using formalin-fixed, paraffin-embedded tumor biopsy samples from breast cancer patients in the early stages.

Abstract
Malignancies rarely occur in somatic parts of mature cystic teratoma of the ovary. Squamous cell carcinoma is the most common form of cancer that can develop in mature cystic teratoma. Other less frequent malignancies include melanoma, sarcoma, carcinoid, and germ cell neoplasms. Only three cases have been reported as papillary thyroid carcinoma arising in struma ovarii. We present a unique case of a 31-year-old female patient who presented with a left ovarian cyst and underwent conservative surgical management in the form of cystectomy. Histopathological examination confirmed the diagnosis of a tall cell subtype of papillary thyroid carcinoma arising from a small focus of thyroid tissue in a mature cystic teratoma of the ovary. The patient was followed up for 60 months with an uneventful clinical course. For a better understanding of such rare cancers, collaborative retrospective studies on large databases with other medical centers are required.

Abstract
Pancreatic cancer, one of the most aggressive tumors, has a dismal prognosis because of the low rates of early identification, fast progression, difficulties following surgery, and the ineffectiveness of current oncologic therapies. There are no imaging techniques or biomarkers that can accurately identify, categorize, or predict the biological behavior of this tumor. Exosomes are extracellular vesicles that play a crucial rule in the progression, metastasis, and chemoresistance of pancreatic cancer. They have been verified to be potential biomarkers for pancreatic cancer management. Studying the role of exosomes in pancreatic cancer is substantial. Exosomes are secreted by most eukaryotic cells and participated in intercellular communication. The components of exosomes, including proteins, DNA, mRNA, microRNA, long non-coding RNA, circular RNA, etc., play a crucial role in regulating tumor growth, metastasis, and angiogenesis in the process of cancer development, and can be used as a prognostic marker and/or grading basis for tumor patients. Hereby, in this concise review, we intend to summarize exosomes components and isolation, exosome secretion, function, importance of exosomes in the progression of pancreatic cancer and exosomal miRNAs as possible pancreatic cancer biomarkers. Finally, the application potential of exosomes in the treatment of pancreatic cancer, which provides theoretical supports for using exosomes to serve precise tumor treatment in the clinic, will be discussed.

Abstract
Stomach (gastric) cancer is one of the most prevalent and deadly cancers worldwide and most gastric cancers are adenocarcinomas. Based on prior research, there is an association between Helicobacter pylori (H. pylori) infection together with the frequency of duodenal ulcer, distal gastric adenocarcinoma, mucosa-associated lymphoid tissue (MALT) lymphoma, and antral gastritis. Helicobacter pylori virulence and toxicity factors have been identified before that significantly influence the clinical outcomes of H. pylori infection and gastric adenocarcinoma. However, it remains unclear exactly how different strains of H. pylori affect gastric adenocarcinoma. Current research suggests this involves tumor suppressor genes, like p27 but also H. pylori toxic virulence proteins. Therefore, we quantified known H. pylori genotypes within adenocarcinoma patients to establish the prevalence of known toxins that include cytotoxin-associated gene A (cagA) as well as vacuolating cytotoxin A (vacA) within patients of variable adenocarcinoma diagnosis. This analysis used gastrectomy samples validated for DNA viability. The incidence of H. pylori in adenocarcinoma patients in Jordan was established to be 54.5% positive (ureA gene positive) with cagA genotype occurrence at 57.1%, but also in this population study vacA gene ratios found to be 24.7%:22.1%:14.3%:14.3%. (vacAs1:vacAs2:vacAm1:vacAm2). Using immunohistochemistry (IHC), we confirmed with statistical significance that p27 was dysregulated and suppressed, within nearly all H. pylori vacA genotypes. In addition, within 24.6% of H. pylori samples analyzed was a different bacterial genotype, and curiously that p27 protein expression was retained in 12% of tested adenocarcinoma H. pylori samples. This is suggestive that p27 could be used as a prognostic indicator but also that an unknown genotype could be contributing to the regulatory effects of p27 protein within this bacterial and cellular environment that may include other virulence factors and unknown immune system regulatory changes.

Abstract
Background and Objectives: Sarcomas are rare malignant tumors of mesenchymal origin. Their low prevalence and histological heterogeneity make their diagnosis a challenging task. To the best of our knowledge, the epidemiology of soft tissue sarcomas (STSs) was not well studied in Jordan. This study thus aimed to determine STS epidemiologic trends at King Abdullah University Hospital (KAUH); a tertiary hospital that provides cancer healthcare for 70% of the population in Irbid Governorate, North Jordan. The findings of this study will provide a good reference point of the burden of STSs in Jordan and the Middle East region. Materials and Methods: All cases with confirmed STS diagnoses who attended KAUH from January 2003 until December 2018 were included in the initial analysis. Bone sarcomas, gastrointestinal stromal tumors and uterine sarcomas were not included in the study. Information collected from the pathology reports and electronic medical records was used to determine STS prevalence, incidence rate, age and gender distributions, histological types and anatomic location. Cases were reviewed by three pathologists with interest in soft tissue tumors. The findings were compared with literature. Results: In total, 157 STS cases were reported (1.9% of cancers diagnosed at KAUH during the 16-year study period). Crude annual incidence rate (IR) per 100,000 person-years ranged from 0.48 in 2015 to 1.83 in 2011 (average = 1.04). Age-standardized IR (ASR)(World WHO 2000–2025) was 1.37. Male:female ratio was 1.3:1. Median age was 39 years. Age ranged from <1 year to 90 years. Overall STS rates increased with age. The most common histological types were liposarcoma (19%), rhabdomyosarcoma (17%) and leiomyosarcoma (10%). The most common anatomic location was the extremity (40.1%), followed by the trunk (14.7%), then head and neck (10.8%). Conclusion: STSs are rare in North Jordan. A slight increase in their incidence was identified during the study period similar to global trends. The collection of relevant data on established risk factors along with a broader scale evaluation of the epidemiology of STS in the Middle East region is recommended to better evaluate disease burden and trends.

Abstract
PURPOSE To investigate the association between obesity and breast cancer clinicopathologic characteristics at presentation along with prognostic impact among Jordanian breast cancer patients. Such data are lacking in Arabian countries. METHODS In this retrospective study, 348 breast cancer patients were included. Analyses were conducted for associations between body mass index (BMI) and age at diagnosis, tumor clinicopathologic characteristics, and molecular subtypes. Eight prognostic factors were considered, and total prognostic scores were calculated. The analysis was stratified by menopausal status. Multivariate logistic stepwise regression analysis was conducted to identify predictors for breast cancer recurrence and death. RESULTS Mean age at diagnosis was 50.98 ± 10.96 years. Mean BMI at diagnosis was 29.52 ± 5.32 kg/m2. Mean age at diagnosis was significantly higher for overweight and obese patients compared to underweight/normal patients (P < 0.001). A significant positive correlation was observed between patient age and BMI at diagnosis (r = 0.251, P < 0.001). Grade of carcinoma was significantly correlated with BMI in the whole population examined (P=0.003). Obese breast cancer patients had significantly higher prognostic scores compared to nonobese cases, indicating worse prognostic features at presentation (P=0.034). Stratification of data analysis based on menopausal status revealed significant associations between obesity and each of tumor stage and grade among postmenopausal but not premenopausal patients (P=0.019 and P=0.031, respectively). Similarly, postmenopausal obese patients had significantly higher prognostic scores compared to nonobese counterparts (P=0.007), indicating worse prognosis, a finding which was also absent among premenopausal breast cancer patients. No significant association between BMI with expression status of hormone receptors, HER2, lymphovascular invasion, and molecular subtypes was found among patients. BMI was a significant predictor for disease recurrence in which obese breast cancer patients had greater odds (2-fold) to develop locoregional and distant recurrence compared to nonobese cases (P=0.011). CONCLUSIONS Obesity was associated with advanced stage and grade of breast carcinoma at diagnosis. The impact of BMI on clinicopathologic characteristics and prognosis was confined to postmenopausal cases. Jordanian obese breast cancer patients are at greater risk of breast cancer recurrence and reduced survival compared to their nonobese counterparts.

Abstract
AIMS One of the main reliable histological features to suggest the diagnosis of inflammatory bowel disease is the presence of significant distortion of the crypt architecture indicating the chronic nature of the disease resulting in mucosal damage. This feature has a considerable intra-observer and inter-observer variability leading to significant subjectivity in colonic biopsy assessment. In this paper, we present a novel automated system to assess mucosal damage and architectural distortion in inflammatory bowel disease (IBD). METHODS The proposed system relies on advanced image understating and processing techniques to segment digitally acquired images of microscopic biopsies, then, to extract key features to quantify the crypts irregularities in shape and distribution. These features were used as inputs to an artificial intelligent classifier that, after a training phase, can carry out the assessment automatically. RESULTS The developed system was evaluated using 118 IBD biopsies. 116 out of 118 biopsies were correctly classified as compared to the consensus of three expert pathologists, achieving an overall precision of 98.31%. CONCLUSIONS An automated intelligent system to quantitatively assess inflammatory bowel disease was developed. The proposed system utilized advanced image understanding techniques together with an intelligent classifier to conduct the assessment. The developed system proved to be reliable, robust, and minimizes subjectivity and inter- and intra-observer variability.

Abstract
L-arginine is a semi-essential amino acid that found naturally in food. It has been shown that administration of large doses of L-arginine can induce acute pancreatitis. In the present study, we evaluated if simvastatin, a 3-hydroxy-methylglutaryl coenzyme A reductase (HMG-CoA reductase) inhibitor, might prevent acute pancreatitis induced by L-arginine. Thirty male Wistar rats were randomly allocated to five groups. Groups were: DMSO, saline, simvastatin, L-arginine, and simvastatin with L-arginine. Twenty four hours after the last dose, rats were sacrificed and their blood was collected from heart for biochemical analysis. Pancreatic tissues were obtained for analysis of glutathione peroxidase (GPx), glutathione s-transferase (GST), lipid peroxide levels (MDA) and histology analysis was examined for pancreas. Results indicated that treatment with simvastatin significantly enhanced levels of GPx and GST and decreased lipid peroxide levels induced by L-arginine compared to the vehicle. Moreover, histopathological analysis further confirmed that administration of simvastatin relatively prevented pancreatic acinar cell damage compared to those animals received L-arginine alone. These findings pointed out the protective role of simvastatin against acute pancreatitis induced by high doses of L-arginine.

Abstract
To assess the immuno-histochemical expression of various markers in, endometrial biopsies of patients with endometrial cancer, and to correlate their expression with the final pathologic findings. Sixty-two patients with primary endometrial cancer who underwent surgical treatment were included in this study. Immuno-histochemical expression of estrogen receptor (ER), progesterone receptor (PR), p53, bcl-2, Her-2/neu and Ki-67 were assessed in curettage specimens, and review of the final pathology report from hysterectomy specimens was carried out. The expression of these markers in curettage was correlated with the final tumor characteristics obtained on hysterectomy specimens. Both ER and PR were significantly more expressed in endometrioid type (EC) than non- endometrioid type (NEC) (P value of 0.004 and 0.012). On the contrary, P53, Her-2 and Ki-67 showed higher positivity in NEC than EC (P value of 0.005, 0.025 and 0.002). Positive expression of ER and PR was significantly associated with low grade tumors and superficial myometrial invasion, whereas positive expression of Her-2 and Ki-67 was significantly associated with higher grade lesions, and deep myometrial invasion. Moreover, a statistically significant inverse relationship was observed between the positivity of P53, Her-2 and Ki-67 and the positivity of ER, PR. We found that determination of immuno-histochemical markers in curettage specimens might be helpful in predicting the final pathologic findings in patients with endometrial cancer. This might be helpful in planning the extensivity of the surgery.

Abstract
Background The human multi-drug resistance gene (MDR1), which encodes the major trans-membrane transporter P-glycoprotein (P-gp), was found to be associated with susceptibility to cancer and response to chemotherapy. The C3435T Polymorphism of MDR1 gene was correlated with expression levels and functions of P-gp. Here, we studied the association between MDR1 C3435T polymorphism and susceptibility to Hodgkin lymphoma (HL) and patient's response to ABVD chemotherapy regimen. Methods a total of 130 paraffin embedded tissue samples collected from HL patients were analyzed to identify the C3435T polymorphism. As a control group, 120 healthy subjects were enrolled in the study. The C3435T Polymorphism was genotyped by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) method. Data analysis was carried out using the statistical package SPSS version 17 to compute all descriptive statistics. Chi-square and Fisher exact tests were used to evaluate the genotype distribution and allele frequencies of the studied polymorphism. Results these studies revealed that the frequency of T allele was significantly higher in HL patients compared to the controls (P < 0.05). In addition, the frequency of CT and TT genotypes were also significantly higher in HL patients compared to the controls (P < 0.05). No association between C3435T polymorphism and response to ABVD was detected among HL patients (P > 0.05). Conclusions these results suggest that MDR1 C3435T polymorphism might play a role in HL occurrence; however this polymorphism is not correlated with the clinical response to ABVD.

Abstract
AimsTo build an automated decision support system to assist pathologists in grading gastric atrophy according to the updated Sydney system.MethodsA database of 143 biopsies was used to train and examine the proposed system. A panel of three experienced pathologists reached a consensus regarding the grading of the studied biopsies using the visual scale of the updated Sydney system. Digital imaging techniques were utilised to extract a set of discriminating morphological features that describe each atrophy grade sufficiently and uniquely. A probabilistic neural networks structure was used to build a grading system. To evaluate the performance of the proposed system, 66% of the biopsies (94 biopsy images) were used for training purposes and 34% (49 biopsy images) were used for testing and validation purposes.ResultsDuring the training phase, a 98.9% precision was achieved, whereas during testing, a precision of 95.9% was achieved. The overall precision achieved was 97.9%.ConclusionsA fully automated decision support system to grade gastric atrophy according to the updated Sydney system is proposed. The system utilises advanced image processing techniques and probabilistic neural networks in conducting the assessment. The proposed system eliminates inter- and intra-observer variations with high reproducibility.

Abstract
OBJECTIVE To demonstrate the immunohistochemical and epidemiological characteristics of gastrointestinal stromal tumors (GIST) in a Middle Eastern population. METHODS This is a retrospective analysis of all intra-abdominal mesenchymal tumors (excluding childhood embryonal rhabdomyosarcoma and small round blue cell tumors) collected from the archives of the Pathology Departments of King Hussein Cancer Center, Amman, and King Abdullah University Hospital, Irbid, Jordan between 2001 and 2008. The immunohistochemical profile of all cases was studied at King Hussein Cancer Center, Amman, Jordan, between January and August 2009. RESULTS Gastrointestinal stromal tumors comprised 45% of the intra-abdominal mesenchymal tumors (42 out of 93 cases), with the most common site being the stomach (n=17, 40.5%). Twenty-seven GIST cases (64.3%) were classified as high risk, 4 (9.5%) as intermediate risk, 6 (14.3%) as low risk, and 2 (4.8%) as very low risk. Immunohistochemistry showed diffuse and strong positivity (+3) for CD117 in 85.7% of GIST cases, and for CD34 in 65% of cases. The high-risk tumors were more common in male patients (M:F=1.7:1), while the non-high risk tumors were more common in female patients. CONCLUSION The immunohistochemical profile of GIST in Jordanian patients is similar to previously published data from other populations, with a slight male preponderance for high-risk GISTs.

Abstract
BACKGROUND Semiquantitative staging of liver fibrosis is a highly subjective procedure and may lead to an uncertainty in judgment regarding the degree of severity and hence the progression of the disease. AIM In this work, we present an automated quantification system (AQS) for evaluating the degree of severity of fibrosis in liver biopsies based on Ishak et al.'s classification. Accordingly, liver fibrosis is classified into six classes depending on its severity and progression. The described system is of special value in accurately assessing the prognosis of chronic liver disease. METHODS In our method, we tried to approximate the architecture of the fibrosis in the subject sample using texture features and shape representation of the fibrosis structural expansion with an overall accuracy of about 98%. RESULTS AND CONCLUSION The presented AQS is considered to be a novel approach in the domain of automatic liver fibrosis quantification. It is a true quantification and intelligent approach that attempts to utilize the current semiquantitative methods of liver fibrosis assessment to turn them into real quantitative ones with significant reduction in variability and subjectivity. We propose that our method can be adopted by a panel of expert liver pathologists and software to be developed and used on a wide scale.

Abstract
The aim of this study was to examine the clinicopathological features and epidemiology of primary gastric lymphoma in Jordan as a model for Middle East countries where such data is scarce. From 1991--2002, 219 patients with primary gastric malignancy were managed at our hospitals. Among these there were 19 patients with primary gastric lymphoma. Pertinent data for these patients were analyzed. Primary gastric lymphoma constituted 65.5% of all gastrointestinal lymphoma and 8.7% of all gastric malignancies. Male-to-female ratio was 2.8:1. The mean age was 56 years (range 39--82). The incidence was 0.6/100,000. The proximal third was the most common localisation. Abdominal pain was the commonest presentation. Low-grade MALT lymphomas, high-grade MALT lymphomas, diffuse large cell B lymphomas and T cell lymphoma were found in 21.1, 26.3, 47.4 and 5.3%, respectively. Nine patients had gastrectomy followed by chemotherapy, 6 patients had palliative resection, 3 patients had chemotherapy only and the remaining patient was treated with Helicobacter pylori eradication. The mean follow-up for all patients was 42.2 months. The 5-year survival rates for stages IE (n=5), IIE (n=4), IIIE (n=6) and IVE (n=4) were 100, 67, 27 and 0%, respectively (p=0.0003). The overall 5 years survival was 48.2%. Primary gastric lymphoma in Jordan shares some epidemiological features with western disease. Jordanian patients are detected and treated after a relatively long delay. Advanced stage at diagnosis correlated with poor outcome. There is a need of an earlier diagnosis and subsequent better care.

Abstract
OBJECTIVE To present our experience with tuberculous mastitis to increase the awareness of surgeons, pathologists and radiologists about this rare disease. PATIENTS AND METHODS Records of nine patients with tuberculous mastitis were retrospectively reviewed. RESULTS Tuberculous mastitis was seen in 0.6% of our patients with surgically treated mammary disease. There were eight females (mean age 32.9 years) and one male. All female patients were parous, two were lactating and one was pregnant. A unilateral breast mass mimicking breast cancer and breast abscess were the presenting feature in seven and two patients, respectively. Two patients had previous pulmonary tuberculosis. Radiological findings were not specific. Fine needle aspiration was performed for seven patients, and excisional biopsy for all patients. The final diagnosis was based on demonstration of acid-fast bacilli in biopsy specimens in two patients, and histopathology aided by polymerase chain reaction in the remaining seven patients. Mastectomy was performed for one patient due to severe breast destruction. All patients had satisfactory results on antituberculosis treatment. CONCLUSION Tuberculous mastitis is a rare entity in patients with mammary disease. A high index of suspicion is the cornerstone for diagnosis. Conservative surgery and anti-tuberculosis drugs seem to be adequate treatment.

Abstract
Idiopathic granulomatous mastitis is a rare disease of the breast. Clinically and radiologically it may mimic breast carcinoma. Awareness of surgeons, pathologists, and radiologists is essential to avoid unnecessary mastectomies. Data regarding 24 patients with histologically confirmed idiopathic granulomatous mastitis treated at our center over 8 years were analyzed. The mean age of patients was 34.3 years. Breast lump was the most common presentation. The right breast was affected in 16 cases. Four patients were pregnant at the time of presentation. Lactation within 6 months of presentation was documented in four patients. Two patients used contraceptives pills. A clinical suspicion of malignancy was present in 17 cases. Mammography was performed in 16 patients and showed focal asymmetrical dense lesions in 9, well-circumscribed opacity in 4, spiculated lesion in 1, and was normal in 2. Fine-needle aspiration was performed in 17 patients, of which 2 were reported as malignant. Wide local excision was the mainstay of treatment. One patient underwent mastectomy upon clinical, mammographic, and repeated cytologic findings consistent with malignancy, and the final histology confirmed idiopathic granulomatous mastitis with no evidence of malignancy. Four patients developed recurrence after a mean follow-up of 31.2 months. A greater awareness of the rare entity of idiopathic granulomatous mastitis is mandatory to avoid unnecessary mastectomies. Clinical, radiologic, and even cytologic findings are sometimes confused with malignancy. To the best of our knowledge, our patient who developed the disease at the age of 11 years is the youngest reported case.

Abstract
AIM The relationship of tumour T-lymphocytic subset infiltration and recurrence in patients undergoing potentially curative resection for colorectal cancer has not been clearly defined. METHODS Tumour sections from patients who had undergone potentially curative resection for colorectal cancer were stained and counted for CD4+ and CD8+ T-lymphocytes. RESULTS Twenty-three patients developed recurrence during the follow-up period. Patients were grouped according to whether or not they developed recurrence. The groups were similar in age, sex, site of tumour, Dukes stage and the numbers of patients receiving adjuvant therapy. The total percentage volume of labelled CD4+ T-lymphocytes in the tumour was significantly lower in the patients who recurred (p<0.05). CONCLUSIONS The results of the present pilot study suggest that a reduction in tumour T-lymphocyte infiltration, in particular CD4+ T-lymphocyte infiltration, is associated with recurrence in patients following potentially curative resection for colorectal cancer.

Abstract
BACKGROUND AND AIM To highlight the epidemiological, clinical, and pathological features of gallbladder cancer in Jordan as a model for the Middle East. Only scattered reports are available from this region. METHODS The histopathological reports and the hospital records for all cholecystectomies performed at Princess Basma Teaching Hospital between 1994-2000 were retrospectively reviewed to identify all patients with gallbladder carcinoma. All the histological slides for the cancer group were reviewed and reclassified by a single pathologist. RESULTS Of 4502 cholecystectomies performed, 33 cases (0.73%) of gallbladder carcinoma were found. The mean age was 61.4 years (range 39-80 years). The male : female ratio was 1 : 3.7. Biliary colic and/or acute cholecystitis were the main presentations. Gallstones were present in 88% (29/33) of the patients. The spectrum of histological subtypes was similar to other series. Only three cases were diagnosed preoperatively, making the incidence of incidental gallbladder cancer 0.66% (30/4502). Simple cholecystectomy was performed for 13 patients. The remaining 20 patients underwent cholecystectomy and portal lymphadenectomy with (five cases) or without (15 cases) extrahepatic resection of the bile ducts. The mean follow up was 22 months (SD +/- 18.95 months; range 1-96 months). The 2-year survival rates for stages I, II, III, and IV were 100%, 42.9%, 10.8%, and 0%, respectively (P = 0.0013). CONCLUSIONS The importance of a high index of suspicion when dealing with cholelithiasis in elderly patients, particularly with large sized stones, cannot be over-emphasized. Proper gross inspection in the theater should be a routine procedure performed by all surgeons. Routine ultrasound for suspected gallbladder stones should always be performed under the supervision of senior radiologists.
