Evaluation of Neutrophil-Lymphocyte Ratio as Inflammatory Marker in Chronic Kidney Disease Stage 3 and 4

Chronic kidney disease (CKD) is a worldwide health problem because of the significant morbidity and mortality which is mostly due to chronic inflammation and proteinuria. Early detection of inflammation and its proper management can prevent further CKD progression and complications. This study aims to observe the association of neutrophil-lymphocyte ratio (NLR) with inflammatory markers in chronic kidney disease stage 3 and 4. In this study, a total of 100 adult patients of CKD stage-3 and 4 were included as study subjects and patient with acute illness, known case of malignancy, cardiovascular and cerebrovascular disease were excluded from the study. From each patient all the relevant history, clinical and laboratory findings were recorded in the data collection sheet. Study subjects were divided into two groups according to NLR value; those who have NLR 0- 3 were in group normal NLR and subjects with NLR >3 in group high NLR. Then markers of inflammation ESR, CRP and serum albumin were compared between these groups. Statistical analysis was done by Statistical Package for Social Science (SPSS) version 22.0. The mean ESR of male and female patients was higher in high NLR subjects than normal NLR subjects. The mean CRP was higher in high NLR subjects than normal NLR subjects. The mean serum albumin was lower in high NLR subjects than normal NLR subjects. The difference of mean ESR, CRP was statistically significant between high NLR and normal NLR subjects but difference of mean serum albumin was not statistically significant. The study findings suggest that high NLR is significantly associated with of inflammatory markers-ESR, CRP. Hence, it can be concluded that NLR could be used as an indicator of inflammation in CKD.

Questionnaire to Survey Cosmetic Outcomes in Laparoscopic Surgery for Colorectal Cancer.

There has been a steady increase in the use of minimally invasive surgery, including conventional multiport laparoscopic surgery (MLS) and single-site laparoscopic surgery (SLS) for colorectal cancer. We aimed to evaluate how important the cosmetic outcome, one of the advantages of SLS, is to patients and whether SLS reflects social needs. We used a web-based questionnaire to survey nonmedical and medical workers for what factors were considered on the assumption that respondents undergo colorectal cancer surgery and that the most important person for them undergoes. Five items (curability, safety, pain, length of hospital stay, and cosmetic outcomes) were compared. After paired photographs before and after SLS and MLS were shown, perceptions of body image and cosmesis were assessed using a visual analog scale. This study included a total of 1352 respondents (990 nonmedical and 362 medical). Curability had the highest score (49.9-53.7 points), followed by safety (23.8-24.7 points). The scores for cosmetic outcomes (6.2-7.1 points) were almost equal to those of the length of hospital stay (6.2-7.1 points), which was associated with medical costs and pain (10.0-11.1 points), one of the main reasons for fear of surgery. Participants who were female, younger, and in the nonmedical group placed great importance on cosmetic outcomes. For all questions regarding body image and cosmesis, SLS had superior scores compared with MLS. Understandably, curability, and safety were most important in colorectal cancer surgery. However, medical workers should consider cosmetic outcomes, even in malignant cases.

Pulmonary lymphangitic carcinomatosis-An experience at autopsy.

Pulmonary lymphangitic carcinomatosis is an uncommon mode of metastases, characterized by diffuse infiltration of the lymphatics malignant cells, and is mainly the subject of case reports or a few case series. The aim of this study is to study the clinicopathological features of this entity at autopsy. This is a retrospective study of data collected over an 11-year period at a tertiary-care hospital. Clinicopathological data of all autopsies with lymphangitic carcinomatosis were analyzed with reference to their demographics, clinical presentation, investigations, sites of primary cancer, and other relevant findings at autopsy. Among 255 cases of malignancies encountered in 7521 autopsies during the study period, 43 patients (16.9%) showed pulmonary metastasis with 22 (13 females and 9 males, mean age of 52.04 years) histologically proven lymphangitic carcinomatosis of the lungs. An antemortem diagnosis was made in only 1 of the 22 cases. The most common sites of carcinoma had been the stomach or the lungs (40.9%) and dyspnea had been the main symptom. The lungs, in addition, showed metastatic deposits and arterial thrombi and/or tumor emboli. The most common nonpulmonary site for metastasis was the liver and lymph nodes. Pulmonary lymphangitic carcinomatosis is often an underdiagnosed clinical entity and the presence of acute progressive respiratory failure in patients with epithelial cancers should raise clinical suspicion. This is one of the largest series to be reported at autopsy.

Changes in Clinical Practice in Adherence to the 2014 American Thyroid Association Guidelines on Thyroid Cancer: A Retrospective Study from a Tertiary Referral Center.

Thyroidectomy, a pivotal treatment for various thyroid disorders, has seen its indications evolve, particularly with the 2014 American Thyroid Association (ATA) Guidelines advocating for conservative surgical approaches like lobectomy. This retrospective study analyzes thyroidectomy practices at a high-volume center from January 2014 to December 2023, focusing on patients potentially eligible for lobectomy per ATA guidelines. The inclusion criteria were tumors < 4 cm, indeterminate thyroid nodules, or differentiated thyroid carcinoma with clinically uninvolved lymph nodes (cN0). This study analyzed the proportion of patients undergoing lobectomy versus total thyroidectomy (TT) and the oncological outcomes. Of 357 patients, 243 underwent TT and 114 underwent lobectomy. The prevalence of lobectomies rose markedly, comprising 73.9% of surgeries in 2023. TT patients were predominantly female (83.5%) and had higher rates of autoimmune thyroiditis (67.5%) and malignancy (89.7%). Lobectomy patients had larger nodules and more indeterminate cytology. Among 301 malignant cases, TT was associated with higher lymph node metastasis, but similar recurrence rates, compared to lobectomy. This study underscores a shift towards lobectomy, reflecting adherence to ATA guidelines and suggesting conservative surgery is feasible without compromising outcomes. Further research on long-term outcomes and refined patient selection criteria is needed to optimize surgical approaches.

P-364 Impact on fertility outcomes in survivors after hematopoietic stem cell transplantation for benign and malignant hematologic disorders: a systematic review and meta-analysis

Abstract Study question What is the prevalence of infertility after hematopoietic stem cell transplantation (HSCT) in females and males up to the age of 1 year? Summary answer The overall prevalence of infertility (95% CI) in women treated with HSTC is 64% (0.58-0.70) and in men 39% (0.31-0.47). What is known already HSCT is a well-established treatment that has significantly increased survival in haematological malignancies and also benign diseases since its introduction in the 1980s. The use of high-dose chemotherapy and radiotherapy, myeloablative conditioning, combined with HSCT exposes serious long-term complications, including gonadal dysfunction and infertility. The risk of ovarian and testicular damage seems to be very high. Therefore, the European Society for Blood and Marrow Transplantation (EBMT) had recommended in 2015 to consider fertility preservation measures in children and adolescents requiring HSCT. However, the data on which this recommendation was based was limited and heterogeneous. Study design, size, duration The systematic review and meta-analysis is part of the FertiTOX project (www.fertitox.com) which aims to close the gap of data regarding gonadotoxicity of cancer therapies to enable more accurate counselling regarding fertility preservation. A systematic literature search was conducted in Medline, Embase and Cochrane in November 2023, considering papers published since 2000. Participants/materials, setting, methods A total of 1632 records were identified for abstract screening. Only females and males without recurrent disease and follow up of more than one year were considered. For the systematic review, 68 studies fulfilled the criteria. For the meta-analysis, studies with &amp;lt; 10 patients were excluded. Infertility was defined in females as very low AMH, hypergonadotropic hypogonadism, amenorrhoea and/or need for hormone replacement therapy and in males as low inhibin B and/or azoospermia. Main results and the role of chance In total, 68 out of 1632 studies were included in the final analysis. Malignant diseases were mainly acute myeloid / lymphoblastic leukemia, chronic myeloid leukemia/ lymphocytic leukemia and non-hodgkin’s and hodgkin’s lymphoma. Benign diseases were sickle cell disease, Fanconi anaemia, and β-thalassemia major. In the meta-analysis, 56 studies were included, comprising 1853 female malignant cases, 241 female benign cases, 1871 male malignant cases, and 226 male benign cases. The analysis, employing a random-effects model for estimating prevalence and its 95% confidence interval, revealed that the overall pooled prevalence of infertility exceeded 30% in all groups. The prevalence of infertility was highest in female malignant cases (65%, 95% CI: 0.58-0.71). In women with benign diseases it was 61% (95% CI: 0.48-0.73). In males with malignant diseases it reached 41% (95% CI: 0.32 to 0.51) and with benign diseases 31% (95% CI: 0.19 to 0.46). Heterogeneity of data was high as shown by female as shown by the malignant cases of 83% and benign cases of 65% in women and the malignant cases of 91% and benign cases of 74% in males. Limitations, reasons for caution The heterogeneity of the included studies due to treatment variations and diverse characteristics of the study populations with large age ranges, did not allow further subgroup analyses. Thus, an individual and reliable fertility prognosis is still difficult to give. Wider implications of the findings The results of this meta-analysis support the clinical necessity of fertility preservation counselling in females and males undergoing HSCT treatment. Further prospective studies addressing the individual impact of the HSCT treatment on gonadal function are needed Trial registration number The study protocol was registered at the international Prospective Register of Systematic Reviews, PROSPERO (Registry number CRD42023486928).

Evaluation of Thyroid Nodule by US Including Elastography versus MRI T2W and Diffusion Sequences

Abstract Background The thyroid gland frequently develops thyroid nodules. Effective treatment of malignant thyroid nodules depends on an early and accurate diagnosis. Benign and malignant thyroid nodules are typically distinguished using conventional thyroid ultrasonography (US). In order to explore changes in tissue stiffness, strain elastography (SE) uses an external force and a deformation response detector. A promising method for distinguishing between benign and malignant thyroid nodules is ultrasound elastography. Malignant versus benign thyroid nodules might be distinguished using MRI apparent diffusion coefficient (ADC) values. This study compares MRI T2W and diffusion sequences with ultrasound, which includes elastography, to assess thyroid nodules. Methods This cross-sectional research was carried out at Ain-Shams University's radiodiagnosis department. It included 23 female or male patients with suspicious thyroid nodule by clinical examination, or ultrasonography including some cases elastography if present for further work up with MR diffusion subjected to DWI and ADC value and results were compared with histopathology if present or follow up of the patients. The duration of the study was 24 months. Results Diffusion had an accuracy of 91.3%, while the ADC value and elastography had a greater diagnostic accuracy with an area under the curve of 95.7% in discriminating between benign and malignant cases. Conclusions When describing thyroid nodules, ADC value provided better diagnostic performance than US TIRADS rating. Over and above ACR-TIRADS classification, useful information is added by ultrasound elastography and strain ratio analysis of thyroid nodules. It is advised as an auxiliary tool. However, the distinction of cancerous and benign thyroid nodules might potentially be done with greater precision using diffusion weighted MRI.

Role of Multi-Detector Computed Tomography (MDCT) in Assessment of Biliary Neoplasms

Abstract Background Biliary neoplasms are commonly encountered in the day-to-day radiological practice and can be benign or malignant. Multidetector CT (MDCT) is a noninvasive imaging modality for evaluation of patients with biliary obstruction, to localize the cause of obstruction, detect the presence of mass lesion, and define its extension and identify remote metastasis. Objective To find out the role of MDCT scan in the evaluation of biliary neoplasms with respect to nature, cause and level of obstruction. Methods During the period from January 2022 to August 2022, the present study included 30 patients with clinically suspected biliary obstruction and previously radiological or laboratory diagnosed cases of biliary malignancy after fulfilling the inclusion and exclusion criteria and taking written /verbal informed consent. 16 patients were males and 14 were females, their ages ranged between 36– 85 years with mean age of 64years old. Results The mean age of participants was 63.73±11.11 years old; and slight male predominance (53.3%). in correlation to histopathological findings, MDCT was 95.2% sensitive in detection of cholangiocarcinoma (20/21*100). It was 100% sensitive in detection of combined cholangiocarcinoma &amp; HCC (1/1*100). Also it was 85.75 sensitive in detection of gall bladder carcinoma (6/7*100). While it was false positive in detection a case of HCC. The sensitivity of MDCT to detect biliary neoplasm is 96.4% (27/28*100) with specificity of 0% (0/2*100), the positive predictive value is 93.1% (27/29*100) while the negative predictive value is 0% (0/1%). We found significant association between MDCT Final outcome with resectability (P-value 0.002) and between resectability and TNM Staging (P-value &amp;lt;0.0001) Conclusion Multidetector computed tomography MDCT can be considered a noninvasive fast with high sensitivity imaging tool in the assessment of patients with biliary neoplasms. The MDCT is satisfactory for staging of biliary neoplasms and for accurate preoperative assessment of the tumor extent.

The Role of CT in Differentiating the Non Pediatric Renal and Adrenal Region Fatty Masses

Abstract Background CT is indicated in many abdominal conditions because of its excellent morphological resolution and its ability to image many different structures, such as abdominal viscera, pelvic organs, lungs and bones, with a single examination. Aim of the Work The aim of this study is to highlight the accuracy of multi-detector computed tomography scan in diagnosing the different fatty lesions of the renal and adrenal regions by comparing the CT study of the benign lesions with their follow up CT scan and comparing the CT study of the malignant cases with their histo-pathological results. Patients and Methods The study was conducted on 34 patients most of them had unrelated complaints(incidental findings) and were referred to Radiology department, Theodor Bilharz Research Institute. Their age ranged from 20 years to 81 years old (mean age 56.35 years±13.61). Most of the patients were males 21cases while female were 13 cases. The patients were referred from oncology, general surgery, and urology departments of Theodor Bilharz Research Institute hospital as well as the outpatient clinics to perform MDCT in the period from September 2021 to June 2022. Results MDCT examinations were done for 34 patients and concluded that MDCT should be used in the first place in the course of diagnostic procedures of patients with renal and adrenal region fatty lesions and this was justified by an overall diagnostic accuracy of 100% for benign lesions and 82% for malignant lesions, where MDCT could correctly diagnose (33/34) cases and only 1 case was misdiagnosed, confirming the ability of MDCT to show up the accurate diagnosis, the exact location, extent of tumor, along with involvement of adjacent organs and vessels. Conclusion It also has a high accuracy in differentiation of malignant from benign lesions and detection of lymph node involvement &amp; metastasis. There by improving the prognosis.

Clinicopathological Characteristics of Multiple Primary Malignancies Involving Female Genital Tract at a Tertiary Cancer Institute of Northeast India

ABSTRACT Background: The term “Multiple Primary Malignant Neoplasms (MPMNs)” refers to two or more unrelated primary malignant neoplasms that originate from single or different organs and occur in one patient. MPMNs have been divided into synchronous and metachronous based on time duration after first malignancy. Materials and Methods: This was a hospital-based retrospective study conducted at a tertiary cancer institute in Northeast India. Clinicopathological factors of patients with multiple primary malignancies with at least one female genital tract malignancy attending the gynecological oncology outpatient department were observed. Those with ambiguous status of primary malignancy and incomplete treatment of first primary malignancy were excluded from the study. Results: A total of 57 patients with MPMN, including one case of triple primary malignancy, were included in the study. 59.18% of cases had metachronous, and 40.81% had synchronous malignancies. The median time to the development of second primary malignancy was 60 months. Among the first diagnosed malignancies, cervix was the most common site (26.5%), followed by endometrium (20.4%) and ovary (14.28%), whereas ovarian malignancy was more commonly diagnosed second malignancy (38.77%), followed by endometrium (14.28%) and cervix (10.2%). In an analysis of synchronous malignancies, the most common genital tract involvement was seen with endometrium and ovary, with a predominance of low-grade endometrioid histology in 75% of cases. Conclusions: As the cancer survivor population continues to increase in future, these patients must be comprehensively evaluated on follow-up, and a cognizance of prior treatment taken should be kept. In addition, it is vital that the clinicians keep a lookout for high-risk population in which genetic testing may be beneficial.

Sinonasal Malignancy Following Cranial Irradiation: A Scoping Review and Case Report of Sinonasal Teratocarcinosarcoma.

Background Radiation therapy is a mainstay of treatment for brain tumors, but delayed complications include secondary malignancy which may occur months to years after treatment completion. Methods We reviewed the medical records of a 41-year-old female treated with 60 Gy of radiation for a recurrent astrocytoma, who 6 years later developed a locally advanced sinonasal teratocarcinosarcoma. We searched MEDLINE, Embase, and Web of Science to conduct a scoping review of biopsy-proven sinonasal malignancy in patients who previously received cranial irradiation for a brain tumor. Results To our knowledge, this is the first report of a patient to present with a sinonasal teratocarcinosarcoma after receiving irradiation for a brain tumor. Our scoping review of 1,907 studies produced 14 similar cases of secondary sinonasal malignancy. Median age of primary cancer diagnosis was 39.5 years old (standard deviation [SD]: 21.9), and median radiation dose was 54 Gy (SD: 20.3). Median latency time between the primary cancer and secondary sinonasal cancer was 9.5 years (SD: 5.8). Olfactory neuroblastoma was the most common sinonasal cancer ( n = 4). Fifty percent of patients died from their sinonasal cancer within 1.5 years. Conclusion Patients who receive radiation exposure to the sinonasal region for treatment of a primary brain tumor, including low doses or scatter radiation, may be at risk of a secondary sinonasal malignancy later in life. Physicians who monitor at-risk patients must be vigilant of symptoms which may suggest sinonasal malignancy, and surveillance should include radiographic review with careful monitoring for a secondary malignancy throughout the entire irradiated field.

Role of Pap Smear Cervical Cytology in the Diagnosis of Extrauterine Malignancies: Largest Study of 104 Cases from Tertiary Care Cancer Centre in India

Introduction: Extrauterine malignancies in cervical samples are rarely seen. It is important to differentiate these cells from those of primary uterine malignancies to determine appropriate line of further investigations and management. Literature on these lesions is limited largely restricted to case reports. The aim of the present study was to study the spectrum and cytomorphological features of extrauterine malignancies in cervical Pap smears. Materials and Methods: It is a retrospective and descriptive study conducted in Department of Cytopathology from January 2019 to July 2023. All cases of extrauterine malignancies with available cytology material were included in this study. All cases of primary uterine malignancies, i.e., uterine corpus or cervix confirmed by clinical, radiological, and histopathological examination were excluded. Results: 104 out of 11,674 cytology Pap smears were those of extrauterine malignancy. Diagnosis of extrauterine malignancy was given in 47.1% cases, 30.9% were reported as positive for malignancy without giving the possibility of an extrauterine origin, and 22.0% were reported as atypical glandular cells only. In 56 cases where Pap smear was the first investigation which led to the diagnosis. Most common extrauterine malignancy was adenocarcinoma principally from ovarian, colorectal, and vaginal origin. Other epithelial malignancies noted were urothelial carcinoma and invasive breast carcinoma. Among non-epithelial malignancies, we reported vaginal mucosal melanoma, cutaneous melanoma, acute leukaemia, and anaplastic large cell lymphoma. Conclusion: High index of suspicion, presence of squamous and glandular elements with no atypical features, and occasional clusters of cells with marked atypia and usually no necrosis in the background are helpful cytomorphological clues to raise suspicion for extrauterine malignancy. Correlation with serology, radiology, and immunocytochemistry can help in reaching final diagnosis.

Spontaneous tumours indogs: Aclinical and pathomorphological study inKyrgyzstan.

The aim ofthis study isto investigate the correlation between the incidence ofspontaneous tumours ofvarious origins and the localisation indogs with sex, breed, and age factors. Atotal of360tumours with various localisation were studied pathomorphologically. Histopathologic data sets from 360dog tissue samples were processed and statistically examined. Achi-square test ofindependence was conducted toexamine the relationships among the various levels ofthe specified variables. Logistic regression models were employed for dichotomous outcomes toascertain the influence ofcertain explanatory variables onthe tumour types. Characteristic pathomorphological changes observed during examination ofdogs with oncologic diseases were determined. The most common neoplasms were mammary tumours, accounting for 43% ofthe cases. The mammary gland tumours were most common inmongrel dogs (25%), with German Shepherds (17.3%), Poodles, Dachshunds, Central Asian Shepherds (6.7% each), and Rottweilers (5.7%) following. The highest frequency ofthese tumours appeared at8years ofage, predominantly originating from the ductal epithelium, which represented 46.4% ofall the malignant cases.

Multiparametric Ultrasound for Focal Testicular Pathology: A Ten-Year Retrospective Review.

Conventional ultrasonography (US), including greyscale imaging and colour Doppler US (CDUS), is pivotal for diagnosing scrotal pathologies, but it has limited specificity. Historically, solid focal testicular abnormalities often led to radical orchidectomy. This retrospective study evaluated the utilisation of contrast-enhanced ultrasound (CEUS) and strain elastography (SE) in investigating intratesticular focal abnormalities. A total of 124 cases were analysed. This study underscored the superior diagnostic capabilities of CEUS in detecting vascular enhancement in all malignant cases, even those with undetectable vascularity by CDUS. It also highlighted the potential of CEUS in identifying distinctive vascular patterns in benign vascular tumours. Definitive confirmation of benignity could be obtained when the absence of enhancement was demonstrated on CEUS. While SE alone offered no distinctive advantage in differentiating between benign and malignant pathologies, we demonstrated that incorporating a combination of CEUS and SE into the evaluation of focal testicular abnormalities could improve diagnostic performance metrics over conventional CDUS. Our findings underscore the role of advanced ultrasound techniques in enhancing the evaluation of focal testicular abnormalities in clinical practice and could aid a shift towards testis-sparing management strategies.

The underlying mechanism of chimeric antigen receptor (CAR)-T cell therapy triggering secondary T-cell cancers: Mystery of the Sphinx?

The U.S. Food and Drug Administration (FDA) has reported cases of T-cell malignancies, including CAR-positive lymphomas, in patients receiving B cell maturation antigen (BCMA)- or CD19-targeted autologous CAR-T cell immunotherapy. These reports were derived from clinical trials and/or post-marketing adverse event data. This finding has attracted widespread attention. Therefore, it is essential to explore the potential mechanisms by which chimeric antigen receptor (CAR)-T cell therapy triggers secondary T-cell cancers to further guarantee the safety of CAR-T cell therapy.

IL-9 is a Biomarker of BIA-ALCL Detected Rapidly By Lateral Flow Assay.

A delayed seroma around breast implants is the most common clinical presentation of BIA-ALCL. However, most seromas are due to benign causes. Therefore, it is essential to distinguish benign seromas from seromas due to BIA-ALCL. In a prior study mean concentrations of IL-9, IL-10 and IL-13 were found to be significantly higher in BIA-ALCL than in benign seromas. The aim of this research was to test the ability to detect high concentrations of IL-9 rapidly with a lateral flow assay (LFA). Because we previously reported that a LFA for CD30 detected BIA-ALCL in seromas we compared CD30 and IL-9 LFAs in distinguishing BIA-ALCL from benign seromas. Thirty microliter samples of 26 seromas (15 benign, 11 malignant) were tested on in-house prepared strips for IL-9 and CD30. Nanoparticle-conjugated antibodies specific to IL-9 and CD30 were used for detection. IL-9 was analyzed in undiluted samples and CD30 samples were optimized at 1:3 dilution. The dynamic range of detection was determined by spiking recombinant IL-9 into a benign seroma. Image analysis measured intensity of both test line (TL) and control line (CL) and a TL/CL ratio was calculated. IL-9 protein and IL-9 transcription factor PU.1 were stained in BIA-ALCL lines and clinical samples. The IL-9 LFA was reliable in distinguishing BIA-ALCL from benign seromas when the concentration of IL-9 was greater than 10 ng/ml. The CD30 LFA was positive in all 11 malignant cases. In one case with only faint CD30 and IL-10 test lines, the IL-9 LFA was clearly positive. Immunohistochemistry showed IL-9 and its essential transcription factor PU.1 were present in tumor cells in BIA-ALCL lines and clinical samples. IL-9 is a tumor cell biomarker of BIA-ALCL that can be detected by lateral flow assay and immunohistochemistry. Concentrations of IL-9 greater than 10 ng/ml reliably distinguished BIA-ALCL from benign seromas. Moreover, IL-9 LFA could detect BIA-ALCL when CD30 LFA was not definitive and IL-10 was of low concentration with a faint IL-10 TL, suggesting a multiplex LFA including IL-9, CD30 and IL-10 might be more effective in detecting BIA-ALCL in selected cases.

The value of the radiological diameter-to-thickness ratio in patients with HER2-positive resectable advanced gastric cancer: implications for long survival and stage migration.

To investigate the clinical significance and stage migration effect of radiological diameter-to-thickness (DT) ratio in HER2-positive resectable advanced gastric cancer (HER2-p RAGC). 369 HER2-p RAGC patients were retrospectively enrolled and information on clinical pathological characteristics, radiological DT ratio, and outcomes [i.e., overall survival (OS) and progression-free survival (PFS)] was collected. Pearson's Chi-square and Student's t-test were employed to compare baseline characteristics. Clinical outcomes were estimated using Kaplan-Meier analysis and Log-rank test. Univariate and multivariate Cox regression models were utilized to analyze independent prognostic factors. HER2-p RAGC patients were stratified into two groups using a DT ratio cutoff value of 4.0 (p < 0.05). Patients with a DT ratio < 4.0 exhibited significantly longer OS (58.0 vs. 31.0months) and PFS (43.0 vs. 24.0months) than those with a DT ratio ≥ 4.0. DT ratio significantly predicted prognosis for N0 and II stage patients (p < 0.05). Patients with gastric body and antrum cancers demonstrated longer OS and PFS in the DT ratio < 4.0 group (p = 0.046, 0.017, 0.036 and 0.028). Multivariate Cox proportional hazard model identified age, pathological T category, pathological N category, pathological TNM category and DT ratio as independent prognostic factors. Notably, pStage II patients with a DT ratio ≥ 4.0 exhibited a similar prognosis to pStage III patients with a DT ratio < 4.0 (p = 0.418 for OS, 0.867 for PFS). Radiological DT ratio could evaluate the prognosis and detect higher malignant cases in HER2-p RAGC patients. Moreover, DT ratio might guide clinicians make postoperative strategies. Retrospectively registered.

Detection of Breast Lumps with Fine Needle Aspiration Cytology: Experience of 50 Cases in Bangladesh

Background: Detection of breast lump is very crucial. Objective: This study was carried out to evaluate the effectiveness of FNAC as a diagnostic method for breast lump. Methodology: This cross sectional study was conducted among 50 women with breast lump at Popular Medical College Hospital, Dhaka, Dhaka Medical College Hospital and Ad-Din Barrister Rafique Ul Huq Hospital, Dhaka during the period of November 2021 to April 2022. This study was conducted using convenient type of non-probability sampling technique. Data were collected by face to face interview, clinical examination and findings of both cytological and histopathological examination. Results: The study revealed the most benign breast lesion (89.45%) were below the age of 40 years and most of the breast cancer (91.2%) were above the age of 40 years. The study showed that 29 cases (58.0%) were diagnosed as benign clinically but cytologically 30(60.0%) cases were benign. Clinically 14(27.0%) cases were malignant but cytologically 13(26.0%) cases malignant. Clinical diagnosis of 8(7.5%) cases were uncertain, whereas cytologically 2(4.0%) cases were suspicious of malignancy and 1(2.0%) case was atypical. The comparison study between cyological and final histopathological diagnosis showed that out of 28 benign lesions diagnosed cytologically among which only 2 cases were found malignant histologically like false negative 2 (7.20%). 13 malignant cases were diagnosed cytologically which were confirmed histologically like no false positive was found. The study found that sensitivity of FNAC 85.3% of the presence of breast cancer and specificity 100.0% for absence of breast cancer. They also showed that the negative predictive value of FNAC for benign breast lump was 93.5% and positive predictive value for malignant breast lump was 100.0% and the overall diagnostic accuracy was 95.40%. Conclusion: In conclusion, FNAC can be used as a diagnostic method in the management of breast lump which has reasonable sensitivity and specificity.

Mini-laparotomy in emergency general surgery in a second-level hospital: a prospective study

Background: Mini-laparotomy (ML) is one of the approaches aimed to reduce intraoperative stress and enhance recovery in surgical patients. The objective was to determine how safe and feasible ML access is in emergency surgery. Methods: This prospective, two-group, parallel active-controlled study evaluated adult patients operated on for acute abdominal conditions at a second-level hospital. Patients explored with the use of ML and those having standard laparotomy access (SL) formed two arms of the study. Cases of abdominal malignancy, generalised peritonitis, and patients scheduled for relaparotomy procedure were excluded. Length of hospital stay and 30-day morbidity/mortality were primary endpoints. Secondary outcomes were operative time, estimated blood loss during the procedure, and postoperative pain control. Results: Thirty-five patients were explored through ML, and 33 had an SL incision. The size of ML ranged from 6 to 12 cm, with the median being 10.5 cm. Employment of ML was associated with reduced length of stay (p=0.008), shorter operative time (p=0.003), and minimised need for opioid analgesia (p=0.008); however, the difference in postoperative complications was not statistically significant (ML: 20% versus SL: 27%, p=0.48) and mortality was similar in both groups (6%). Conclusion: Our data demonstrate that ML is a safe technique that could be used for the treatment of urgent abdominal conditions in selected patients. Having comparable postoperative morbidity with the SL approach, it might lead to reduced pain and enhanced recovery after the procedure.

Professor Oral Pathology, Islamabad Dental Hospital, Islamabad 6Demonstrator Oral Pathology Margalla Institute of Health Sciences, Islamabad Author`s Contribution 1Conception and idea acquisition of data, 2Data Analysis, 3Results interpretation, 4Editing and drafting, 5Critical Revision, 6Final approval of the study to be published Funding Source: None Conflict of Interest: None Received: February 02, 2024 Accepted: May 27, 2024 Address of Correspondent Dr. Zainab Niazi Associate Professor Oral Pathology, Islamabad Dental Hospital, Islamabad dr.zainabniazi@gmail.com ABSTRACT Objectives: To evaluate the diagnostic accuracy of fine needle aspiration cytology (FNAC) by comparing its findings with the gold standard histological features of salivary gland lesions. Methodology: This retrospective study was conducted at the Department of Histopathology, Islamabad Medical and Dental Hospital (IMDC), from January 2023 to December 2023, patients presenting with salivary gland swellings. Fifty-seven patients having salivary gland swelling were included on which both histological and cytological evaluation had been done. Twenty cases were excluded because either they had lack of correlation between FNAC and histology or on view of inadequate material. All the patients were clinically evaluated clinically and FNAC was done using 10ml disposable syringe and 23/24-gauge needle without using local anesthesia. The histopathology of the surgical specimens and cytology of the FNAC specimens were compared, and the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were evaluated. Results: On FNAC, 37 cases were diagnosed cytologically, as 9 cases identified malignant and 28 as benign. Histopathological examination confirmed 9 malignant cases and 25 benign cases, whereas 3 cases were classified as false positive. The specificity and sensitivity of FNAC were 75% and 94%, respectively. Overlapping cytological features, heterogeneity, and unsampled areas were the primary factors contributing to false-positive. Conclusion: This study showed that salivary gland FNA cytology is a valuable diagnostic technique for salivary gland lesions, however due to great variation in pleomorphic adenoma, the samples must be confirmed by histopathological features.
