Abstract
Background The aggregation of clonal plasma cells causes plasma cell neoplasms, which vary in severity and clinical outcomes. The present research focused on the epidemiological, clinical, immunologic, and cytogenetic characteristics of plasma cell neoplasms. Methods In this five-year retrospective cross-sectional study, demographic information such as age and sex, calcium elevation, renal insufficiency, anemia, and bone lesion (CRAB) characteristics, as well as laboratory data including bone marrow and peripheral blood film results, immunohistochemistry, flow cytometry, and cytogenetic study outcomes were collected at Shiraz University of Medical Sciences, Shiraz, Iran. The collected data were analyzed using SPSS Statistics software (version 20.0). Descriptive statistics were reported as numbers, percentages, and mean±SD. Results 417 newly diagnosed plasma cell neoplasm patients were confirmed by bone marrow or other tissue biopsy tests. 279 patients were men (66.9%). The most prevalent age group was 60-64 years old (18.46%). Plasma cell myeloma (PCM) affected 355 (85.13%) patients, while monoclonal gammopathy of undetermined significance (MGUS) affected 6 (1.43%) patients. Solitary plasmacytoma was seen in 56 (13.42%) patients. At the time of diagnosis, 119 (33.52%) of 355 PCM patients were asymptomatic, whereas 236 (66.47%) patients had at least one CRAB symptom, 55 (15.49%) had two or more, and 14 (3.94%) had three or more. There were 7 (1.97%) cases of amyloidosis. Cytogenetic abnormalities were found in 51.28% (40/78) of the patients. Twenty-one individuals (52.5%) were hyperdiploid with multiple trisomy, while 19 (47.50%) were not. Conclusion When diagnosed, Iranian PCM patients might have more advanced disease. PCM was more prevalent in young adults, and hyperdiploid was the most common cytogenetic finding in this investigation.

Abstract
BACKGROUND The effect of vaccination on the SARS-CoV-2 baseline viral load and clearance during COVID-19 infection is debatable. This study aimed to assess the effects of demographic and vaccination characteristics on the viral load of SARS-CoV-2. METHODS We included the patients referred for outpatient SARS-CoV-2 qRT-PCR (reverse transcriptase quantitative polymerase chain reaction) test between July and September 2022. Cycle threshold (Ct) data were compared based on the demographic and vaccination characteristics. A generalized linear model was used to determine the factors associated with the SARS-CoV-2 PCR Ct value. RESULTS Of 657 participants, 390 (59.4%) were symptomatic and 308 (47.1%) were COVID-19 positive. Among 590 individuals with known vaccination status, 358 (60.6%) were booster vaccinated, 193 (32.6%) were fully vaccinated, 13 (2.2%) were partially vaccinated, and 26 (4.4%) were unvaccinated. Most vaccinated patients received inactivated vaccines (70.5%). The median Ct value was 20 [IQR: 18-23.75] with no significant difference between individuals with different vaccination statuses (P value = 0.182). There were significant differences in Ct value in terms of both symptom presence and onset (both P values < 0.001). Our regression model showed that inactivated vaccines (P value = 0.027), mRNA vaccines (P value = 0.037), and the presence and onset of symptoms (both P values < 0.001) were independent factors significantly associated with the viral load. CONCLUSION The SARS-CoV-2 baseline viral load is unaffected by vaccination status, yet vaccination might accelerate viral clearance. Furthermore, we demonstrated that the presence and onset of symptoms are independent variables substantially associated with the patient's viral load.

Abstract
Pulmonary Lymphangioleiomyomatosis (LAM) is a rare disease of the lung and lymphatic system that primarily affects women of childbearing age. LAM is a progressive disease with a terrible prognosis, which worsens over time and is extremely difficult to treat. In this study, we discuss the case of a 31-year-old woman with LAM who was initially misdiagnosed with leiomyoma and the way that led to a true diagnosis and effective treatment. Following a precise diagnosis based on comprehensive clinical data and particular immunohistochemical tests, sirolimus treatment was initiated, and the patient entirely responded to the treatment. This case report demonstrated that LAM is an uncommon condition that is challenging to diagnose, which causes its treatment to be delayed.

Abstract
Background & Objective Brain tumors are the most frequent solid tumors in children. High-grade tumors are more challenging in diagnosis. Atypical teratoid rhabdoid tumor (ATRT) may be mistaken for other high-grade brain tumors. Molecular genetic analysis of ATRT has shown deletion and mutation in the hSNF5/INI1 gene in most of the cases. The INI1 protein expression can be helpful for the accurate diagnosis. Methods In this study, immunohistochemical staining (IHC) using INI1 antibody was performed to determine the possibility of ATRT misdiagnosis. Totally, 147 tumors including 6 ATRTs, 81 medulloblastomas, and 60 other CNS tumors were examined in children between 0 and 17 years old. Results No nuclear staining was found in the six ATRT cases, while most of other CNS tumors demonstrated nuclear staining. Five cases were previously diagnosed with medulloblastoma, primitive neuroectodermal tumor (PNET), and anaplastic oligodendroglioma, while the diagnoses were changed to ATRT based on the re-evaluation of the H&E slides and INI1 study. Additionally, two cases were recurrent tumors whose features were consistent with those of ATRT. The INI1 immunostaining was negative in these cases. Conclusion INI1 was very helpful in distinguishing ATRT from its mimickers in challenging cases. All known ATRT cases in this study were immunonegative for INI1. Thus, INI1 is recommended to be used in the initial IHC panel for the high-grade brain tumors, especially in children under the age of three years, so that they can benefit from intensified therapeutic regimens.

Abstract
INTRODUCTION Myeloproliferative neoplasms (MPNs) are divided into BCR-ABL positive Chronic myeloid leukemia (CML) and BCR-ABL negative MPNs including Polycythemia vera (PV), Essential Thrombocythemia (ET) and Primary myelofibrosis (PMF). Evaluation of the Philadelphia chromosome in MPNs is a diagnostic requirement for classic CML. CASE REPORT In 2020, a 37-year-old woman with negative cytogenetic testing for Janus kinase2 (JAK2), Calreticulin (CALR), myeloproliferative leukemia virus oncogene (MPL), and positive for BCR-ABL1 mutation with reticular fibrosis in bone marrow was diagnosed as CML. Some years ago, the patient had been diagnosed with PMF with evidence of histiocytic necrotizing lymphadenitis or Kikuchi-Fujimoto disease (KFD). The BCR-ABL fusion gene was initially evaluated which was negative. Then, Cutaneous squamous cell carcinoma (cSCC) was confirmed by Dermatopathologist with palpable splenomegaly and high white blood cell (WBC) count with basophilia. Finally, BCR-ABL was detected positive by the fluorescence in situ hybridization (FISH) and quantitative real-time polymerase chain reaction (qRT-PCR). In fact, the co-occurrence of PMF with CML was identified. CONCLUSION This case study highlighted the importance of some cytogenetic methods in the detection and classification of MPNs. It is recommended that physicians pay more attention to it and be aware of the planning treatment.

Abstract
BACKGROUND The concept of critical value is not evident in surgical pathology, and there is no established protocol for determining, reporting, and documenting these results. MATERIALS AND METHODS A questionnaire was designed regarding critical value in surgical pathology, and all pathologists and some clinicians from five laboratories were asked to participate through an invitation link. The most important items were selected, and all pathologists were instructed to follow a standard operating procedure to deal with critical results for a year. RESULTS A total of 43 pathologists and 44 non-pathologists participated in the study. Some critical or unexpected items were selected. Most participants agreed that the optimal time to announce critical reports is within 24 h of establishing the final diagnosis, and a phone call was the most dependable communication option. In addition, the most qualified recipients were the attending physicians. Therefore, a written policy was implemented for a year. One hundred seventy-seven critical or unexpected cases (0.5%) were detected. Mucormycosis and cytomegalovirus (CMV) were the most frequent critical cases. CONCLUSION There are no set criteria for critical items or the reporting process in surgical pathology. It is possible to establish more uniform norms for reporting these cases by boosting pertinent research efforts and recruiting more pathologists and physicians. Additionally, it is advised that each medical facility compile its own unique critical or unexpected diagnosis list.

Abstract
INTRODUCTION Malignant serous effusions are common in metastatic carcinomas. Although cytomorphology is recognized as the gold standard diagnostic method, it exhibits moderate sensitivity. This study aimed to assess the diagnostic value of immunophenotyping with a single epithelial marker, known as the epithelial cell adhesion molecule (EpCAM, CD326), in discriminating malignant metastatic carcinomas of serous fluids. METHODS This prospective study was conducted on suspicious or confirmed cases of malignant tumors from September 16, 2019, to June 21, 2020. Serous fluid samples were assessed via cytomorphology using the Wright-Papanicolaou method and the anti-EpCAM mouse monoclonal antibody (clone VU-1D9) flow cytometry. The EpCAM(+)/CD45(-) immunophenotype was defined as the metastatic involvement of carcinoma in the serous cavity. RESULTS A total of 118 samples (90 females and 28 males; mean age, 54.04 ± 16.14 years), collected from peritoneal and pleural fluids, were examined in this study. Five samples (4.24%) were positive in both EpCAM flow cytometry and cytology, while 102 samples (86.44%) were negative for both EpCAM flow cytometry and cytology, yielding an overall agreement of 92%, 84%, and 90.7% for the peritoneal, pleural, and total samples, respectively. Based on the Bayesian latent class model, the EpCAM flow cytometry showed sensitivity and specificity of 58.5% (95% CI: 0.3, 99.7) and 96.2% (95% CI: 47.8, 100), respectively. The corresponding values were 68.7% (95% CI: 0.3, 99.9) and 96.1% (95% CI: 47, 100) for cytology, respectively. CONCLUSION The EpCAM flow cytometry and cytology showed comparable performance in detecting metastatic effusions. The EpCAM flow cytometry might have a diagnostic value in decreasing the false-negative rate of cytomorphology, while maintaining excellent specificity.

Abstract
INTRODUCTION Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) and T cell/histiocyte-rich large B-cell lymphoma (THRLBCL) have overlapping histological features that make their diagnosis challenging. Insulin-like growth factor II mRNA-binding protein 3 (IMP3) is a recently proposed diagnostic marker for Hodgkin's lymphoma. The aim of this study was to determine the ability of IMP3 in differentiating NLPHL from THRLBCL. METHODS In this retrospective study, the formalin-fixed paraffin-embedded blocks from 56 patients (28 NLPHL and 28 large B cell lymphoma (LBCL, including 16 THRLBCL and 12 DLBCL, NOS) cases based on immunohistochemistry (IHC) were included. Sample sections were stained for IMP3 using IHC method. Moderate to strong staining in at least 10% of tumor cells was considered positive IMP3 expression. RESULTS The mean age of the patients was 41.25 ± 16.08 years old. The majority of the patients were male. There was a significant age difference between NLPHL (34.61 ± 16.44 years old) and LBCL (47.89 ± 12.85 years) groups (p = 0.001). No significant difference was seen in gender and site between NLPHL and LBCL groups. The expression of IMP3 was mainly strong in LBCL group, while it was heterogeneously distributed among NLPHL samples ranging from weak to strong (p < 0.001). It was determined that strong IMP3 expression at 55.00% can differentiate LBCL from NLPHL with 71.4% sensitivity and 71.4% specificity. CONCLUSION Our findings showed that IMP3 may be a good complement in differentiating NLPHL cases from THRLBCL.

Abstract
Mutations in tumor suppressor p53 protein can occur at different phases of malignant transformation and affect the patient's prognosis. This study aimed to evaluate the expression of mutant p53 protein in Iranian patients with the primary and recurrence oral squamous cell carcinoma (OSCC). This retrospective cross-sectional study conducted on a group of patients with the primary OSCC (n=122) and the control subjects with oral noncancerous reactive lesions (n=80). Immunohistochemistry was performed with the DO-7 monoclonal antibody against p53 protein, and samples with ≥10% immunostaining were considered positive. Statistical analyses were carried out using SPSS. Positive staining for p53 was observed in none of the control subjects and 57.4% (70 of 122) of the primary OSCC patients (p<0.0001, OR=107.69, 95%CI=6.49-179.0). The p53 immunopositivity had no significant differences between males and females (54.2% vs. 62%, p=0.390), but significantly different between those aged below and over 50 years (p<0.0001, OR=4.52, 95%CI=1.07-12.05). During follow-up, OSCC recurrence occurred in 104 patients, but the phenotype of the mutant p53 protein in patients who relapsed was the same as in matched primary tumors (p=0.763). Risk of recurrence had no significant differences between p53-positive and p53-negative cases (p=0.953), males and females (p=0.263), and age below and over 50 years (p=0.223). Despite its confirmed diagnostic value, the immunoexpression of the p53 mutant protein in OSCC in cancer recurrence was the same as in the primary tumor. However, further studies with a larger sample size and longer follow-up are needed to confirm or change our conclusions.

Abstract
Introduction Palpable thyroid nodules are stated in 4 to 7% of individuals. This study was designed to evaluate the relation of Thyroid Imaging Reporting and Data System (TIRADS) and fine-needle aspiration (FNA) based cytology reports in patients with thyroid nodules. Materials and Methods In this retrospective cross-sectional study, individuals with thyroid nodules who were selected for ultrasonographic-guided FNA enrolled in this study. Demographic data, radiologic assessment, and cytology report were gathered based on hospital medical records. TIRADS grading of the nodules was assessed for each nodule. Cytology was performed on all samples. Sensitivity and specificity were calculated by comparing cytology with ACR-TIRADS and also cytology with TIRADS 4-5 cut-off point as a radiologic malignant lesion. Results 172 patients were studied, 151 of whom were female and 21 were male. The mean age of the patients was 49.46 years. Most of the patients had TIRADS 4 (53.5%) followed by 3 (31.4%), and 5 (11.6%). 151 patients (87.8%) had a benign lesion in cytology. Of them, 118 had colloid nodules. There was a statistically significant relation between TIRADS and cytology (p-value<0.001). Sensitivity, specificity, AUC, and positive and negative predictive value for ACR-TIRADS classification were 76.19%, 47.54%, 0.619, 20.00%, and 92.06%, respectively. These values for cut-off "4-5" classification was 86.36%, 38.00%, 0.622, 16.96%, and 95.00%. Conclusions According to the significant concordance between TIRADS and cytology, as shown in the results of our study, it seems that TIRADS could be used to decrease the amount of unnecessary FNA in individuals with thyroid nodules.

Abstract
BACKGROUND Although the primary origin of some carcinomas may be obscure to clinicians, its identification is crucial as it affects prognosis and treatment (especially novel targeted therapies). Immunohistochemistry (IHC) may be helpful in identifying the primary origin of carcinomas. This retrospective survey aimed to evaluate the frequency and accuracy of each IHC marker used to determine the origin of carcinomas. METHODS The review of pathology department archives revealed 307 cases of cancer of unknown primary origin (CUP) between 2015 and 2020, which were accessible in the department archives. Demographic information, site of biopsy, clinical and pathologic diagnoses, and IHC results of the patients were collected. RESULTS The patients included 157 (51.15%) men and 150 (48.85%) women. The age of the patients ranged from 14 to 92 years, including 106 (34.5%) expired cases. In 27% of cases, the primary origin of carcinoma remained unknown. The agreement between pathologic and clinical diagnoses was 59%. The most common pattern of cytokeratin (CK) expression in CUP was CK7+/CK20- (55.3%), followed by CK7-/CK20- (19%), CK7+/CK20+ (15%), and CK7-/CK20+ (10.7%), respectively. CONCLUSION The IHC analysis may improve the diagnosis of CUPs. However, the origin of some cases remains unknown despite an IHC analysis, thereby necessitating the use of more diagnostic procedures or gene expression studies for reaching a definitive diagnosis.

Abstract
BACKGROUND Mantle cell lymphoma (MCL) has remained incurable in most patients. The expression of PD-L1 as a prognostic and predictive marker has not been fully evaluated in MCL. The current study aimed to determine PD-1/PD-L1 expression in MCL specimens and its significance as an immune check point inhibitor. METHODS This retrospective study was conducted on the formalin-fixed paraffin-embedded blocks of 79 confirmed MCL patients based on immunohistochemistry (IHC). The IHC method was used to stain patient samples for PD1 and PDL1. Positive PD-1/PD-L1 expression was defined as moderate to strong or memberanous or memberanous/cytoplasmic staining in at least 5% of tumor and/or 20% of associated immune cells. Tumor aggressiveness was determined based on Ki67 and variant. RESULTS The mean age of the patients was 60.08 ± 10.78 years old. Majority of the patients were male. The prevalence of aggressive tumor was 25%. Positive PD1 and PDL1 expression were identified in 12 (15.0%) and 3 (3.8%) of tumor cells, respectively. PD1 and PDL1 were positive in zero (0%) and 7 (8.9%) of background cells, respectively. There was no significant difference in terms of study parameters between positive and negative groups for both PD1 and PDL1 proteins. PD1 tumor cell percentage was negatively correlated with age (r = -0.254, p = 0.046). CONCLUSION Our results suggest that neither PD-1 nor its ligands represent relevant targets for MCL treatment. Age may impact the efficiency of immune checkpoint inhibitors and could be related to the increased incidence of MCL with age.

Abstract
Aim: To control the spread of Acinetobacter baumannii in hospitals, it is necessary to identify the reservoir of organisms and the way they are transmitted. This study analyzed samples by BOX-PCR and enterobacterial repetitive intergenic consensus PCR techniques. Methods: Isolated strains were identified using the Microgen kit and blaOXA-51 gene. The genetic diversity of strains that were sensitive or resistant to colistin was evaluated by BOX-PCR and enterobacterial repetitive intergenic consensus PCR methods. Results: A total of 13% of the isolates were resistant to colistin, whereas 87% of the strains were sensitive to this medication. A. baumannii strains that were resistant or sensitive to colistin were divided into five groups using the BOX-PCR method and six groups using the enterobacterial repetitive intergenic consensus PCR method. Conclusion: Rapid identification and the use of appropriate tools to control colistin-resistant clones are essential to prevent the further spread of A. baumannii.

Abstract
Schwannoma is a rare tumor in the colon which originates from the peripheral nerve plexus. Most of the cases have been asymptomatic but occasionally present as an obstructive mass. Abdominal investigations are effective in some cases, but usually, they are not informative. A significant number of cases have been detected after their operation by histopathology examination. Immune and histochemical staining shows the spindle cells that have been positive for S-100 and vimentin, but negative for CD34 and smooth muscle actin. If the diagnosis of Schowannoma is confirmed preoperatively, segmental resection is recommended. In this case report, we presented a 58-year-old woman with pelvic mass and normal colonoscopy that mimic extramural large uterine myoma with extraluminal pressure effect on the rectosigmoid.

Abstract
BACKGROUND The purpose of this study was to describe the radiologic and histopathologic features of lacrimal gland in patients presenting with lacrimal gland enlargement. METHODS We retrospectively retrieved the data of patients with lacrimal gland enlargement in Farabi Eye Hospital between 2012 and 2017. These data included demographics, the patients' facial photographs, orbital CT-scans, and histopathological findings of lacrimal gland biopsies. RESULTS Forty-seven patients (15 men and 32 women) were enrolled in this study with a median age of 37.9 years (range, 15-79 years). Histopathologic diagnoses were chronic dacryoadenitis in 26 cases (55.32%), IgG4-related disease in 6 patients (12.77%), two cases of acute dacryoadenitis, two cases of non-necrotizing granulomatous inflammation, two cases of Non-Hodgkin's B-cell lymphoma, two cases of adenoid cystic carcinoma and two cases of mixed tumor (4.26% each), as well as one case of conjunctival epithelial cyst, and one case of benign lymphoid tissue and fibrofatty tissue (2.13%). In two samples (4.26%), biopsy revealed normal lacrimal glands. Interestingly, in two cases with relapsing lacrimal gland enlargement, different histopathologic diagnoses were found in biopsies taken from each lacrimal gland at different times. The average size of enlarged lacrimal glands was 19.67 mm × 7.06 mm on axial CT scan and 19.44 mm × 6.20 mm on coronal CT scan. CONCLUSION Tissue biopsy is needed for diagnosis of lacrimal gland enlargement because it is difficult to distinguish the type of the lacrimal gland pathology based solely on clinical or radiological presentation.

Abstract
INTRODUCTION AND IMPORTANCE Leiomyosarcoma (LMS) of the colon is an extremely rare and highly invasive tumor arising from the muscularis propria of the gastrointestinal tract. After the introduction of oncogenic role of KIT by immunohistochemistry (IHC), the reported cases of gastrointestinal leiomyosarcoma were highly limited. True LMS of the colon is such a rare disorder that there isn't much description of its nature. CASE PRESENTATION We reported two very rare cases of primary leiomyosarcoma of sigmoid colon, which referred to our institution with symptoms of abdominal pain, lower GI bleeding and fatigue. After the initial investigations, both patients were diagnosed with primary LMS of sigmoid colon that underwent laparoscopic tumor resection. CLINICAL DISCUSSION The classical colonic LMS presents with a vast majority of non-specific symptoms including mild abdominal pain, fresh/obscure rectal bleeding, and weight loss. The most common location for colonic LMS is the sigmoid colon, and ascending colon. The prognostic factors for the disease outcome have not been established properly; however, patient age, tumor size/grade, and local/distant dissemination are of great importance. CONCLUSION Herein, we reported two rare cases of primary leiomyosarcoma of sigmoid colon that was treated with laparoscopic surgery.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism, irregular menstruation, ovulatory dysfunction, and insulin resistance. Recent studies have reported the possible role of phytoestrogens in PCOS. This animal study aimed to evaluate the effects of genistein on insulin resistance, inflammatory factors, lipid profile, and histopathologic indices on PCOS. METHODS PCOS was induced by 1 mg/kg of letrozole in adult Sprague-Dawley rats. The rats then received normal saline (PCOS group), 150 mg/kg of metformin, or 20 mg/kg of genistein dissolved in 1% methylcellulose solution for 42 days. Body weight, the glycemic and lipid profile, and inflammatory, antioxidative, and histopathological parameters were assessed at the end of the intervention. RESULTS Treatment with genistein significantly alleviated the increased level of fasting blood insulin (p=0.16) and the homeostatic model assessment of insulin resistance (p=0.012). In addition, the genistein group had significantly lower levels of serum malondialdehyde (p=0.039) and tumor necrosis factor-alpha (p=0.003), and higher superoxide dismutase enzyme activity (p<0.001). Furthermore, the histopathological analysis indicated that genistein administration led to an increase in luteinization and the development of fewer cysts (p<0.05). CONCLUSION Biochemical and histopathological analyses indicated that genistein administration to rats with PCOS induced significant remission in oxidative, inflammatory, and glycemic and histopathologic parameters.

Abstract
Background: This study aimed to compare sheep burnt wool and human amniotic membrane (AM) on second-degree burn wound healing in rats. Materials and Methods: Seventy-two adult male rats of Sprague Dawley underwent general anesthesia, and a deep second-degree burn was created on their skin by a hot iron plate. Afterward, human AM, silver sulfadiazine ointment (SSD), and sheep burned wool were used on wound area for burn treatment. On days 7, 14, and 21 of the experiment, the rats were sacrificed, and histopathological assessments were done. Results: Human AM, in comparison with other groups, significantly (P<0.05) showed better improvement in all pathologic variables. Burned wool showed significant improvement compared to the control group on day 7 in the angiogenesis, on day 14 in granulation tissue formation and epithelial formation, and on day 21 in new epithelial formation (P<0.05). Burned wool compared with SSD ointment in granulation tissue formation improved significantly (P<0.05) on days 7 and 14. Also, SSD ointment in comparison with the control group significantly improved (P<0.05) granulation tissue formation and macrophage on day 7. Conclusion: Human AM has a significant effect on the treatment of second-degree burn. Burned wool has a better effect on wound healing than SSD ointment and negative control group without treatment in terms of granulation tissue and epithelium formation.

In present study, a series of thermo-sensitive cross-linked poly(N-isopropylacrylamide) grafted sodium alginate (Alg-g-pNIPAM) copolymers were synthesized for delivery of curcumin to wound. FTIR, 1H NMR, elemental analysis and DSC showed successful polymerization and precise structure of copolymers. Thermogelation at 27-42 °C depending on the copolymer concentration, chain-length of pNIPAM and pH was observed. The optimum copolymer with proper rheological and syringeability properties showed excellent thermogelling at a wide range of pH and concentration, and could prolong the release of curcumin up to 72 h. In-vivo wound contraction and histopathological evaluations revealed that in addition to the higher efficacy in wound contraction, the curcumin formulation (Cur-F) significantly reduced the inflammation, enhanced the collagenesis and resulted in increased number of fibroblasts. Well-known anti-oxidant and anti-inflammatory properties of curcumin and in situ-forming nature of Alg-g-pNIPAM can make the system an excellent candidate for further investigations.

Abstract
Background: Multiple myeloma is a hematologic malignancy manifested by the secretion of abnormal immunoglobulin. Different methods have been described for diagnosis and patient response to management. Serum free light-chain assay is recently approved in the diagnosis of multiple myeloma patients. This study aimed to evaluate the diagnostic accuracy of serum free light-chain assay and its agreement to bone marrow findings. Materials and Methods: Forty-six patients with the diagnosis of multiple myeloma were enrolled in the study. The patients were grouped into newly diagnosed cases (22 patients,47.8%) and known cases who were under treatment (24 patients,52.2%). Bone marrow study was done and percentage and clonal status of plasma cells were evaluated by a combination of immunohistochemistry and flow cytometry. Free light-chain assay was done in all patients and sensitivity, specificity, positive predictive value, and negative predictive value were analyzed. Results: Thirty of 46 patients showed monoclonal plasma cell infiltration and 16 patients showed polyclonal plasma cell infiltration based on bone marrow findings. An abnormal κ/λ ratio was seen in 15(68.18%) of new cases and 16(66.6%) of known cases. Sensitivity, specificity, PPV and NPV for κ⁄λ ratio were 72.73%, 46.15%, 71%, and 50%, respectively. Conclusion: In conclusion, due to high false positive and false negative results, the presence of an abnormal serum FLC ratio was not equal to the presence of monoclonal gammopathy, and observation of a normal ratio does not exclude the presence of monoclonal gammopathy.

Abstract
BACKGROUND Although life-threatening hemorrhage is a usual manifestation of acute promyelocytic leukemia (APL), thrombotic events seem to be more common in APL compared to other subtypes of acute leukemia. The treatment and prophylaxis of thrombosis are controversial due to the high risk of bleeding caused by disseminated intravascular coagulation (DIC) and thrombocytopenia. To the best of our knowledge we report the first case of APL in a patient with prosthetic heart valves successfully treated with a combination of all-trans-retinoic acid (ATRA) and arsenic trioxide (ATO). We hope this case report helps clinicians to manage different spectra of coagulopathy in APL successfully. CASE PRESENTATION A 38-year-old Asian man presented with diagnosis of APL confirmed by bone marrow biopsy. He was on warfarin due to prosthetic mitral and aortic valves. He was at risk of both hemorrhagic events due to DIC and life-threatening valve thrombosis. Our management regimen included unfractionated heparin adjusted according to the platelet count to prevent both valve thrombosis and bleeding events. The patient tolerated treatment well without any hemorrhagic or thrombotic events, and complete molecular remission was achieved by ATRA and ATO without the need for chemotherapeutic agents. CONCLUSION Although this case is exceptional, a precise evaluation may be needed to select the appropriate dose and type of anticoagulant to treat a patient with APL.

Abstract
AbstractUlcerative colitis is a chronic inflammatory condition of the colon with an unknown etiology. In this study, we aimed to evaluate the therapeutic effects of Cupressus sempervirens extract on the healing of acetic acid-induced ulcerative colitis in rat. Fifty-five male rats divided into five equal treatment groups were used for this study and received the following treatments: Group 1, 250 mg/kg asacol; Group 2, 1 ml gel base (carboxymethyl cellulose); Group 3, 0.5% gel form of C. sempervirens extract; Group 4, 1% gel form of C. sempervirens extract, and; Group 5, considered as negative control and received 1 ml of normal saline. Body weight changes, histopathological and antioxidant changes in the colon tissue were evaluated. Significant weight gain was observed in rats that received 1% gel extract of C. sempervirens. Significant superoxide dismutase activity was also detected in 0.5 and 1% gel extract groups compared to C. sempervirens extract, Asacol and in 1% gel extract groups compared to the gel base group. Furthermore, both gel extract groups had significant lower total antioxidant capacity compared to Asacol group. Several histopathological lesions including inflammation, ulceration, crypt disarray, and goblet cell depletion were detected in the different groups, however, the mean rank of pathological changes showed no significant difference among the five groups. In summary, our results showed that hydroalcoholic extracts of C. sempervirens leaves produces healing effects in acetic acid induced ulcerative colitis.

Abstract
Since March 2020, the pandemic of coronavirus disease 2019 (COVID-19) has become a threat to global health. Several kinds of coronavirus-associated disorders, including vascular involvements with neurological symptoms, have been reported worldwide. Here, we describe two individuals with COVID-19 with no history of traumatic brain injury nor of vascular injuries, who developed spontaneous subdural haematoma in a subacute process. Both individuals became lethargic and unresponsive during admission in the intensive care unit. Both have undergone emergent craniotomy with acceptable outcome. The first patient improved significantly and was discharged a week after surgery. However, the second individual had no improvement on her consciousness and died 3 days after surgery. Haemorrhagic events, including subdural haematoma, can happen during COVID-19 infection with several possible mechanisms. Brain imaging and further neurological evaluation must be performed in any individuals with COVID-19 who show signs of alteration in their state of consciousness.

Abstract
Abstract
Objective To investigate the effects of hydroalcoholic extract of Ziziphus jujuba on the histopathological, tissue oxidative stress and inflammation plus to antioxidant pathways of colon tissue in rat with induced Ulcerative colitis.
Materials and methods Ulcerative colitis was induced in 80 rats those divided into 8 equal groups. Group 1 and 2 were negative controls receiving 1 mL/day of normal saline in enema and oral; group 3 and 4 as positive control 1 and 2 received 10 mg/kg of intra-colonic asacol and oral mesalazine; groups 5 and 6 received 20% and 40% of hydroalcoholic extract of Z. jujuba trans-rectally; group 7 and 8 received 1500 and 3000 mg/kg of hydroalcoholic extract of Z. jujuba orally, respectively. After 7 days, animals were evaluated for colon tissue histopathology, levels of malondialdehyde and IL-1β, and activities of superoxide dismutase, glutathione peroxidase and myeloperoxidase in colon tissue.
Results Hydroalcoholic extract of Z. jujuba in both forms of trans-rectal and oral administration especially in the higher doses could result into a more healing effect in damaged colonic tissue, more reduce glutathione peroxidase and IL-1β level. Also, these two doses (gel 40% and oral 3000 mg/kg) could more decrease the myeloperoxidase activity and stimulate superoxide dismutase and glutathione peroxidase activities. Also, gel 40% in transrectal administration was more potent than administration 3000 mg/kg in oral.
Conclusion The results of the present study indicated that Z. jujube may be considered as a treatment of choice for Ulcerative colitis especially in gel form and also in dose-dependent pattern.

Abstract
Abstract
Background
The arrival of highly effective, well-tolerated, direct-acting antiviral agents (DAA) led to a dramatic decrease in hepatitis C virus (HCV) prevalence. Human immunodeficiency virus (HIV)-HCV–coinfected patients are deemed a priority population for HCV elimination, while a rise in recently acquired HCV infections in men who have sex with men (MSM) has been described. We describe the variations in HIV-HCV epidemiology in the French Dat’AIDS cohort.
Methods
This was a retrospective analysis of a prospective cohort of persons living with HIV (PLWH) from 2012 to 2018. We determined HCV prevalence, HCV incidence, proportion of viremic patients, treatment uptake, and mortality rate in the full cohort and by HIV risk factors.
Results
From 2012 to 2018, 50 861 PLWH with a known HCV status were followed up. During the period, HCV prevalence decreased from 15.4% to 13.5%. HCV prevalence among new HIV cases increased from 1.9% to 3.5% in MSM but remained stable in other groups. Recently acquired HCV incidence increased from 0.36/100 person-years to 1.25/100 person-years in MSM. The proportion of viremic patients decreased from 67.0% to 8.9%. MSM became the first group of viremic patients in 2018 (37.9%). Recently acquired hepatitis represented 59.2% of viremic MSM in 2018. DAA treatment uptake increased from 11.4% to 61.5%. More treatments were initiated in MSM in 2018 (41.2%) than in intravenous drug users (35.6%). In MSM, treatment at the acute phase represented 30.0% of treatments in 2018.
Conclusions
A major shift in HCV epidemiology was observed in PLWH in France from 2012 to 2018, leading to a unique situation in which the major group of HCV transmission in 2018 was MSM.

Abstract
Ulcerative colitis (UC) is one of the most well-known types of inflammatory bowel disease that manifests as recurrent inflammation of rectum and colon. The goal of this study is to evaluate the protective effects of shark liver oil (SLO) on acetic acid-induced ulcerative colitis in rats. Eighty induced UC rats were randomly divided into ten equal groups and received the following treatments for seven days: 1 ml of normal saline rectally, 1 ml of gel base (carboxymethyl cellulose) rectally, 10 mg/kg of Asacol rectally, 10 mg/kg of mesalazine orally, 5% gel form of SLO rectally, 10% gel form of SLO rectally, 200 mg of SLO orally, and 400 mg of SLO orally. We examined the oxidative stress indices, histopathological features, and body weight changes, as well as the function of the liver and kidneys at the end of treatment. Administration of 10% rectal and 400 mg oral SLO resulted in a significant weight gain. Also, glutathione peroxidase activity was significantly higher in 5% and 10% SLO-treated groups, and elevated superoxide dismutase activity in rats that received 5% SLO was observed compared to negative control and Asacol groups. While no significant changes were observed in most of the kidney and liver function markers, higher levels of aspartate aminotransferase were detected in the group that received 400 mg SLO orally compared to negative control and Asacol groups. Many histopathological signs of improvement were observed in mesalazine, Asacol, and SLO groups. There were no significant changes detected in the mean rank among different groups. Our data indicate that SLO supplementation could improve the amelioration of acetic acid-induced UC in rats due to its antioxidant effects.

Abstract
Purpose Progesterone has been reported to inhibit the proliferation of breast cancer and osteosarcoma cells; however, its inhibitory mechanism has not yet been clarified. The aim of the present study was to clarify the effects of progesterone on apoptosis in breast cancer (MCF-7) and human osteosarcoma (MG-63) cells. Materials and methods In this experimental study the cytotoxic effect of progesterone was measured in MCF-7 and MG-63 cells exposed to different concentrations of progesterone using MTT assay, and effective concentrations were identified. The expression levels of the Bax, P53 and Bcl-2 genes were evaluated by real-time PCR, and caspase-3, 8 and 9 activity levels were determined using a colorimetric method. Hoechst staining and flow cytometry were used to confirm apoptosis. The data were statistically analyzed using one-way analysis of variance (ANOVA) and independent-samples t-test. Results Compared to the control group, we observed a significant increase in the expression levels of the Bax and P53 genes and the activity levels of caspase-3 and 9, and a significant decrease in the expression level of the Bcl-2 gene in MCF-7 and MG-63 treated with effective concentration of progesterone. The caspase-8 activity level did not change significantly in treated MG-63 but increased in treated MCF-7 cells. Hoechst staining and flow cytometry results confirmed apoptosis in the cells exposed to effective concentration of progesterone. Conclusions The cytotoxic effect of progesterone on breast cancer and osteosarcoma cells was mediated by apoptotic pathways. In this context, progesterone triggers the extrinsic and intrinsic apoptotic pathways in MCF-7 cells and induces the intrinsic apoptotic pathway in MG-63 cells.

Abstract
Abstract
Background: ARID1A has been described as a tumor suppressor gene, participating in chromatin re-modeling, epithelial-mesenchymal-transition and many other cellular and molecular processes. It has been cited as a contribute in tumorigenesis. The role of ARID1A in CRC is not yet defined.
Aim: To investigate the role ARID1A methylation and CNV in its expression in CRC cell lines and to examine the relationship between ARID1A status with survival and clinicopathologic characteristics in patients with CRC.
Methods: We used RT-PCR to determine both CNV and expression of ARID1A from six CRC cell lines. And used MSP to evaluate methylation of ARID1A. We used (IHC) to ARID1A protein expression, and, evaluate both MSI and EMAST status in 18 paired CRC and adjacent normal tissues. Statistical analysis was performed to establish correlations between ARID1A expression and other parameters.
Results: Among the 18 CRC tumors studied, 7 (38.8 %) and 5 tumors (27.7%) showed no or low ARID1A expression, respectively. We observed no significant difference in ARID1A expression for overall patient survival, and no difference between clinicopathological parameters including MSI and EMAST. However, lymphatic invasion was more pronounced in the low/no ARID1A expression group when compared to moderate and high expression group (33% VS. 16.6% respectively. ARID1A promoter methylation was observed in 4/6 (66%) of cell lines and correlated with ARID1A mRNA expression level ranging from very low in SW48, to more pronounced in HCT116 and HT-29/219. Treatment with the methyltransferase inhibitor 5-Azacytidine (5-aza) resulted in a 25.4-fold and 6.1-fold increase in ARID1A mRNA expression in SW48 and SW742 cells, respectively, while there was no change in SW480 and LS180 cells. No ARID1A CNV was observed in the CRC cell lines.
Conclusion: ARID1A expression is downregulated in CRC tissues correlate with it being a tumor suppressor protein. This finding confirms ARID1A loss of expression in CRC development. Our in-vitro results suggest high methylation status associates with reduced ARID1A expression and contribute to CRC tumorigenesis. There was no significant association between the ARID1A loss of expression and clinicopathological characteristics. ARID1A might be a useful biomarker for colorectal cancer. Future in- vivo analysis is warranted to further established this role.

Abstract
BACKGROUND Resveratrol and Berberis integerrima (B. integerrima) are known to be natural antioxidants and regulators of human metabolism. However, the effects of resveratrol and B. integerrima on the ovarian morphology in polycystic ovary syndrome (PCOS) are not obvious. OBJECTIVE This study aimed to determine the effect of the hydroalcoholic extract of B. integerrima in combination with resveratrol on some biochemical parameters and ovarian morphology in the letrozole-induced PCOS rat. MATERIALS AND METHODS Seventy adult female Sprague-Dawley rats aged 10-12 weeks weighing 200 ± 20 gr were randomly divided into seven groups (n = 10/each). Group I): normal; Group II): vehicle; Group III): letrozole-induced PCOS 1 mg/kg letrozole orally, rats receiving 1 cc normal saline orally; Group IV): PCOS + receiving 150 mg/kg metformin orally; Group V): PCOS + receiving 20 mg/kg resveratrol orally; Group VI): PCOS + 3 gr/kg barberry orally; and Group VII): PCOS + receiving 3 gr/kg barberry and 20 mg/kg resveratrol orally. All animals were followed-up for 63 days. The biochemical parameters and histological assessments of ovaries were performed. RESULTS Resveratrol alone and/or in combination with B. integerrima treatment in rats led to a significant decrease in low-density lipoprotein, triglyceride, malondialdehyde, and tumor necrosis factor-alpha concentrations (p = 0.02). The groups IV, V, VI, and VII showed a decrease in insulin resistance and an increase in the superoxide dismutase, total antioxidant capacity, and high-density lipoprotein (p = 0.01). No significant difference was observed between the level of serum glucose in the treatment groups. Number of cystic follicles had a significant decrease in barberry, resveratrol, and their combination groups (p < 0.001). CONCLUSION Resveratrol, B. integerrima, and their combination as natural products with fewer side effects might be effective as an alternative medicine in treatment of PCOS.

Abstract
Background & Objective: Thiopurine drugs are considered as a treatment modality in various autoimmune disorders including pemphigus vulgaris (PV). These drugs are metabolized by an enzyme “Thiopurine S-methyl transferase” (TPMT). Various variants of this enzyme may have decreased activity leading to serious drug side effects. To investigate the phenotype and genotype of TPMT in PV patients receiving thiopurine drugs. Methods: A total of 50 patients (29 women and 21 men) with pemphigus vulgaris treating with standard dose of Thiopurine drugs were selected. Sex, age, result of liver function test and complete blood count were recorded. Genotyping of two common non-functional allele (TPMT*2 and TPMT*3C) by Allele-specific and RFLP-PCR was performed. TPMT enzymatic level was determined by an ELISA based method. Results: Of patients, 36 (72%) were found to have normal TPMT level; and 12, (24%) had higher level of enzyme and 2, 4% had low TPMT enzyme, but none of the patients showed mutant TPMT*2 and TPMT*3C alleles. None of the patients showed hepatotoxicity and bone marrow suppression. Conclusion: The phenotypic assay based on ELISA method may have false positive and misleading results but genotyping using PCR-RFLP and allele specific PCR is accurate, simple and cost-effective and can be used in patients decided to undergo thiopurine treatment.

Abstract
Background Radiation-induced skin injury remains a serious concern, which may limit the duration and dose of radiation treatment. The concept that stem cell injection may reduce tissue injury or assist its recovery after radiation has been recently argued. Herein, we examined the effect of adipose-derived mesenchymal stem cells (ASCs) on radiation-induced skin damage in rats. Methods This study is an experimental case control study. ASCs were isolated from peri uterine fat tissue of the rats. Then the rats received a 30 Gy single dose radiation to their buttocks skin using gamma radiation. Next day stem cells were transplanted subcutaneously in 16 rats as the case group. A group of 16 rats was considered as control group with radiation but no transplantation of stem cells. Then rats were examined and observed by macroscopic analysis and phenotypic scores during 4 weeks of follow up. Results The wound size in control group was significantly higher than case group in the second, third and fourth weeks of evaluation (P<0.05). There was no significant difference in skin lesion severity, pathological factors, and the onset of recovery signs between two groups (P>0.05). Conclusions It seems that using ASCs alone has not profound effects on reducing radiation-induced cutaneous complications, while combination of these cells with growth factors may produce more promising results.

Abstract
Introduction: Primary Diffuse Large B Cell Lymphoma of CNS (PCNSL) is a rare variant of Diffuse Large B Cell Lymphoma (DLBCL) and presents with an aggressive clinical course and usually resistant to commonly used therapy regimens. Recently, role of immune checkpoint molecules including PD-1 and PD-L1 confirmed in some solid tumors and lymphoma resulting tumor cells escape the immune system and help to survive and to spread. Inhibitors of PD-1 and PD-L1 have shown lasting responses in several solid and some hematological tumors, while limited studies evaluate checkpoint molecules on PCNSL. Method: In this study, we investigated PD-1 and PD-L1 expression by immunostaining on 71 patients with PCNSL and correlation with demographic data, location of the tumor, proliferation rate, cell of origin, and CD8 positive T cell infiltration in tumor microenvironment. Results: 16 from71 showed PD-1 expression, while PD-L1 expression were 42/71. No association was determined between PD-1/PD-L1 expression and gender, cell of origin, and proliferation rate, but a highly significant difference was determined between the infiltration of CD8 positive T cells in two groups of PD-1/PD-L1 positive and negative. Conclusion: This study revealed expression of check point molecules in remarkable number of PCNSL which may open new therapeutic recommendations in this aggressive lymphoma type.

Abstract
The urinary bladder schwannoma is an extremely rare primary urologic tumor. Schwannoma arises from the Schwann's cells in the nerve sheaths and is almost associated with von Recklinghausen's disease. We report a case of schwannoma in a 35-year old female who presented with urinary frequency for 2 months with absence of evidence of von Recklinghausen disease and successfully treated with transurethral resection of bladder lesion (TUR_B). To the best of our knowledge, this represents only the 10th case of benign schwannoma of the urinary bladder in a patient without von Recklinghausen disease. We report a case of an isolated schwannoma of the urinary bladder, and also searched the English literature as we had access to bladder schwannoma.

Abstract
INTRODUCTION Hemophagocytic lymphohistiocytosis (HLH) is caused by overactivation of immune system. Gene mutations, infections, malignant, and autoimmune trigger the development of the disease. MATERIALS AND METHODS Clinical data and peripheral blood samples of 21 patients suspected of HLH were collected in Shiraz Medical Centers 2017-2018. Peripheral blood samples were analyzed for soluble interleukin-2 receptor alpha (sIL2Rα) marker (sCD25), and the results were compared with 36 normal controls as well as comparison with clinical findings and other laboratory parameters. RESULTS Twenty-one patients (11 males and 10 females) with an average age of 5.2 were investigated. In this study, peripheral blood samples were taken from 16 newly diagnosed patients before treatment, and five were posttreatment blood samples. The mean sIL2Rα level before treatment in 16 patients was 9023 pg/ml. The mean peripheral blood sample of the 36 controls was 3025 pg/ml. The mean of the five posttreatment samples was 4198 pg/ml. Significant difference between pretreatment and the control group was observed. However, no significant difference was detected between after treatment samples and the control group. By comparing the sIL2Rα levels between patients with increased aspartate aminotransaminase (AST) and patients with normal AST level, there was a significant difference in the amount of IL2Rα level. CONCLUSION This study highlights the importance of IL2Rα marker in the diagnosis and follow-up, during treatment and suppression. Furthermore, a significant difference with respect to AST level requires further investigation.

Abstract
Background There are several scolicidal agents for inactivation of hydatid cyst protoscolices during surgery, but most of them are associated with adverse side effects such as sclerosing cholangitis (SC) and liver necrosis. The present study aimed to evaluate the adverse effects of Eucalyptus essential oil to induce SC in animal models. Materials and Methods Eighteen rabbits weighting 2000-3500 g were included in three groups for this study. About 0.3 ml of Eucalyptus essential oil (1%), or 5% hypertonic saline, or normal saline was injected for 5 min in the gallbladder. After 4 months, the liver, common bile duct, and duodenum were resected and immediately sent for cholangiography and pathologic studies. Results According to pathological studies, inflammation is more common in Eucalyptus and hypertonic saline groups. Due to cholangiographic studies, stricture was slightly higher in the hypertonic saline group than the Eucalyptus group. Conclusion Thus, 1% Eucalyptus essential oil is at least as safe as 5% hypertonic saline, but for clinical uses, it must be confirmed with further studies.

Abstract
Introduction Pathology must aim at a correct diagnosis, which is complete and useful for clinicians. However, in routine practice, there are multiple sources of errors in the pathology results, which have several impacts on the patient’s treatment and outcome. Case presentation Our patient is a 66 years old man, case of rheumatoid arthritis with lymphadenopathy due to vasculitis, which was underdiagnosed due to lack of complete clinical data during pathologic examination. Since the patient was extremely ill, and the workup was inconclusive, the pathology slides were sent to our center for consultation and molecular study to rule out lymphoma. The slide review was done with complete access to the patient’s history and status. In addition to reactive follicular hyperplasia, there was inter-follicular/paracortical plasma cell infiltration and remarkable leukocytoclastic vasculitis of small vessels. Discussion Most frequent errors in the laboratories are preanalytical, due to clinical failures (wrong clinical procedure, inappropriate ordering, erroneous, incomplete or misleading clinical information), and specimen transportation and delivery. Surgical pathology by its nature depends heavily on the input of clinicians and surgeons who are fully aware of patient condition. Conclusion This case clearly shows the importance of communication between the pathologist and clinicians and the impact on patient care. Clinicians should also provide complete clinical data for the pathologist. Full access to clinical information improves the pathologist’s ability to make an accurate diagnosis.

Abstract
AIM This study aimed to compare the effects of synbiotic soymilk fortified with whey protein concentrate and zinc sulfate with lactulose on bile duct ligated-induced HE. BACKGROUND Hepatic encephalopathy (HE) is seriously associated with neuromuscular and cognitive alterations. METHODS Eighty-two Sprague Dawley rats were randomly assigned into seven groups (sham, bile duct ligation (BDL), BDL + lactulose, BDL + soymilk (SM), BDL + Synbiotic soymilk (SSM), BDL + SSM + whey protein concentrate (WPC), BDL + SSM + WPC + ZnSO4). Different SM products, lactulose, and normal saline were administered via oral gavage (2 mL/rat/day). The serum and liver markers as well as liver histopathology were assessed after 28 days. RESULTS The SM products significantly reduced the serum alanine aminotransferase, albumin, and ammonia (P < 0.05). The levels of aspartate aminotransferase, endotoxin, and liver interleukin-6 improved significantly in all treatments, except for those receiving SM. SSM and SSM + WPC + ZnSO4 were the only effective products in reducing serum alkaline phosphatase (P < 0.05). Furthermore, the liver total antioxidant capacity was greater (P<0.05) in the SSM + WPC and SSM + WPC + ZnSO4 groups. The histopathological examinations confirmed the efficiency of all SM products in reducing liver fibrosis. Liver bile duct proliferation diminished only in the SSM + WPC and SSM + WPC+ ZnSO4 groups (P<0.05). CONCLUSION This study showed the positive effects of different SM products, especially SSM + WPC and SSM + WPC + ZnSO4, on HE. Further studies are required to confirm our findings.

Abstract
Purpose Currently, neoadjuvant chemoradiation (CRT) followed by total mesorectal resection is considered the standard of care for treating locally advanced rectal cancer. This study aimed to investigate the efficacy and feasibility of adding induction chemotherapy to neoadjuvant CRT in locally advanced rectal cancer. Methods This phase-II clinical trial included 54 patients with newly diagnosed, locally advanced (clinical T3–4 and/or N1–2, M0) rectal cancer. All patients were treated with 3 cycles of preoperative chemotherapy using the XELOX (capecitabine + oxaliplatin) regimen before and after a concurrent standard long course of CRT (45–50.4 Gy) followed by standard radical surgery. Pathologic complete response (PCR) rate and toxicity were the primary and secondary endpoints, respectively. Results The study participants included 37 males and 17 females, with a median age of 59 years (range, 20–80 years). Twenty-nine patients (54%) had clinical stage-II disease, and 25 patients (46%) had clinical stage-III disease. Larger tumor size (P = 0.006) and distal rectal location (P = 0.009) showed lower PCR compared to smaller tumor size and upper rectal location. Pathologic examinations showed significant tumor regression (6.1 ± 2.7 cm vs. 1.9 ± 1.8 cm, P < 0.001) with 10 PCRs (18.5%) compared to before the intervention. The surgical margin was free of cancer in 52 patients (96.3%). Treatment-related toxicities were easily tolerated, and all patients completed their planned treatment without interruption. Grade III and IV toxicities were infrequent. Conclusion The addition of induction chemotherapy to neoadjuvant CRT is an effective and well-tolerated treatment approach in patients with rectal cancer.
