    Rectus abdominis muscle endometriosis
    (College of Physicians and Surgeons Pakistan, 2014) Goker A.; Sarsmaz K.; Pekindil G.; Kandiloglu A.R.; Kuscu N.K.
    Endometriosis is characterized by an abnormal existence of functional endometrial tissue outside the uterine cavity, typically occuring within the pelvis of women in reproductive age. We report two cases with endometriosis of the abdominal wall; the first one in the rectus abdominis muscle and the second one in the surgical scar of previous caesarean incision along with the rectus abdominis muscle. Pre-operative evaluation included magnetic resonance imaging. The masses were dissected free from the surrounding tissue and excised with clear margins. Diagnosis of the excised lesions were verified by histopathology.

    Inflammatory Prognostic Index in Metastatic Renal Carcinoma Treated with Nivolumab
    (College of Physicians and Surgeons Pakistan, 2022) Ekinci F.; Erdogan A.P.; Yildirim S.; Bulut G.; Yilmaz C.; Barutca S.
    Objective: To evaluate the utility of inflammatory prognostic index (IPI), albumin, c-reactive protein (CRP), and lactate dehydrogenase (LDH) as predictive biomarkers of oncologic outcome in metastatic renal cell cancer (mRCC) patients treated with nivolumab. Study Design: Descriptive study. Place and Duration of Study: Manisa Celal Bayar University, Aydın Adnan Menderes University, Bitlis Tatvan State Hospital and Private Hatay Defne Hospital Medical Oncology Clinics, Turkey, from January 2017 to June 2020. Methodology: Seventy-five mRCC patients treated with nivolumab between January 2017 and June 2020 were enrolled. Several factors were retrospectively investigated, including IPI, CRP, LDH, and albumin level, for their association with progression-free survival (PFS) and overall survival (OS). The IPI was calculated as CRP × NLR/albumin. Univariate and multivariate analyses were performed to assess the prognostic value of relevant factors. Results: When analysed according to the calculated IPI score, it is seen that the group with <2.153 has an OS duration of 96.3 months, while the group with ≥2.153 has a shorter time of 42.9 months (p=0.02). In the analysis performed according to albumin level, it was reported that those with low levels (22.8 months) had worse median OS than those with high levels (92.8 months) (p=0.004). According to the cox regression analysis results, it was determined that those with a high IPI score significantly increased the risk of death compared to those with a low score (HR:2.4, p=0.023). However, this significance could not be confirmed in the multivariate analysis. It was analysed that those with low albumin levels significantly increased the risk of death compared to both univariate analysis (HR:3.3, p=0.007) and multivariate analysis (HR:4.4, p=0.003). Conclusion: Those with high IPI scores and low albumin levels were associated with worse median OS. However, only the multivariate analysis analysed albumin level as an independent prognostic variable. Prospective and more extensive research is needed to consolidate the potential prognostic power of these markers. © 2022 College of Physicians and Surgeons Pakistan. All rights reserved.

    Is crp/albumin ratio (car) a new parameter to be added to risk stratification systems in metastatic renal cell carcinoma patients?
    (College of Physicians and Surgeons Pakistan, 2022) Uzun M.; Yildirim E.C.; Ekinci F.; Semiz H.S.
    Objective: To evaluate the effect of pretreatment C-reactive protein (CRP)/Albumin ratio (CAR) on prognosis and its association with IMDC (International metastatic renal cell carcinoma database consortium) risk score and overall survival (OS) in metastatic renal cell carcinoma (mRCC) patients. Study Design: Descriptive study. Place and Duration of Study: Department of Medical Oncology, Dokuz Eylul University, Izmir, Turkey, between 2007 and 2020. Methodology: Clinico-pathological and treatment-related data of mRCC patients were retrospectively evaluated and included in the study. CAR was used as a prognostic inflammatory score. CAR threshold value for OS has been obtained by ROC analysis. The prognostic value of CAR was tested using Kaplan-Meier and Cox-regression models. IMDC-CAR model was created by adding CAR to IMDC risk stratification. Results: OS was 91 months in patients with CAR below the threshold value of 0.072 (0.072), while OS was 51 months in patients with CAR of 0.072 and above (p=0.005). According to IMDC risk stratification, intermediate and poor risk groups showed similar survival times (p0.05). However, when CAR was added to the IMDC risk score in the intermediate group, it was divided into 3 subgroups with different prognoses (p=0.02). Conclusion: CAR is an independent predictor of OS in mRCC patients. In this study, it has been demonstrated that more accurate prognosis prediction could be made by adding CAR to IMDC indicators in the intermediate risk group, which constitutes a highly heterogeneous group according to IMDC risk stratification. © 2022 College of Physicians and Surgeons Pakistan.

    HALP Score as a New Prognostic Index in Metastatic Renal Cell Cancer
    (College of Physicians and Surgeons Pakistan, 2022) Ekinci F.; Balcik O.Y.; Oktay E.; Erdogan A.P.
    Objective: To evaluate prognostic significance of the new index, designed by formulating hemoglobin, albumin, lymphocyte, and platelet (HALP) counts in patients with metastatic renal cell carcinoma (RCC). Study Design: Descriptive study. Place and Duration of Study: Department of Medical Oncology, Celal Bayar University, Manisa, Turkey and Adnan Menderes University, Aydin, Turkey, from January 2014 to April 2020. Methodology: Patients with metastatic RCC and sufficient follow-up data were included in the study as a retrospective cohort. HALP score was calculated as hemoglobin (g/L) × albumin (g/L) levels × lymphocyte count (/L)/platelet count (/L). The cut-off value was determined by examining the area under the ROC curve for the HALP value. The endpoints of this study included overall survival (OS) and progression-free survival (PFS). Results: The mean overall survival (OS) of the patients with low HALP score was 17.7 months (95% CI, 2.21 - 33.18), while the OS of the patients with high HALP score was 89.7 months (95% CI, 55.62 - 123.77) and reached statistical significance (p=0.001). The results of univariate (p = 0.009) and multivariate (p=0.012) analyses were statistically significant as well. Conclusion: The HALP score in metastatic RCC patients was closely related to the prognosis. Worse OS was found in patients with a low HALP score. © 2022 College of Physicians and Surgeons Pakistan.

    Systemic Immune Inflammation Index as a Key Marker of Survival and Immune-related Adverse Events in Immune Checkpoint Inhibitor Therapy
    (College of Physicians and Surgeons Pakistan, 2022) Ekinci F.; Balcik O.Y.; Demir B.; Gursoy P.; Ozveren A.; Erdogan A.P.
    Objective: To evaluate the prognostic significance of the new index designed by formulating neutrophil, lymphocyte, and platelet counts in patients with metastatic disease receiving immune checkpoint inhibitors (ICI) and its effect on the immune-related adverse events (irAEs). Study Design: Cohort study. Place and Duration of Study: Department of Medical Oncology, University of Manisa Celal Bayar, University of Aydin Adnan Menderes, and University of Ege, and Izmir Kent Hospital, Turkey, from January 2016 to April 2020. Methodology: Patients with metastatic disease receiving ICI sufficient follow-up data were included. Patients, who had received treatment for a minimum of 3 months, were evaluated for the response. Systemic immune-inflammation index (SII) was calculated as neutrophil (/L) × (lymphocyte (/L) / platelet (/L). The cut-off value was determined by examining the area under the receiver operating characteristic (ROC) curve for the SII value. The endpoints of this study included overall survival (OS) and progression-free survival (PFS). Results: A total of 168, patients who received ICI in the metastatic stage, were evaluated. The OS of the patients with low SII scores was 110.8 months (95% CI, 88.2-133.5), while patients with high SII scores were 36.0 months (95% CI, 28.4-43.6) and reached statistical significance (p <0.001). The results of univariate (HR=3.376, 95% CI, 1.986-5.739, p<0.001 and multivariate (HR=2.792, 95% CI, 1.495-5.215, p=0.011) analyses were statistically significant as well. Conclusion: The SII score in patients with metastatic disease receiving ICI was closely related to the prognosis. Patients with a high SII score are associated with a worse prognosis, these patients develop fewer irAEs. © 2022 College of Physicians and Surgeons Pakistan. All rights reserved.

    Histopathological Results of Conjunctival Masses with Suspected Malignancy Based on Slit-lamp Biomicroscopy
    (College of Physicians and Surgeons Pakistan, 2023) Erdogan M.; Mayali H.; Malgaz S.; Altinisik M.; Ilker S.S.
    Objective: To evaluate the histopathological results of conjunctival masses suspected to be malignant based on biomicroscopic examination. Study Design: Observational study. Place and Duration of the Study: Department of Ophthalmology, Celal Bayar University, Hafsa Sultan Hospital, Manisa, Turkiye, from November 2013 to February 2021. Methodology: Patients who underwent excision for the diagnosis and treatment of conjunctival surface masses with clinical suspicion of malignancy were evaluated retrospectively. The masses were categorised as benign, premalignant, and malignant lesions according to the histopathological results. The distribution of conjunctival masses was analysed according to patients’ gender and age groups. Results: The study included 98 conjunctival masses in 98 patients (57.1% men, mean age 48.6±21.85 years). On pathological examination, 63 of the masses were found to be benign (64.3%), 22 were premalignant (22.4%), and 13 were malignant (13.3%). The most common benign lesion was nevus (n=21, 21.4%). All detected premalignant lesions were conjunctival intraepithelial neoplasms (CIN), detected in 22 patients (22.4%). Of these, 13 patients (13.3%) had carcinoma in situ (CIN III). Thirteen (13.3%) of the masses were malignant, the most common being squamous cell carcinoma (n=10, 10.2%). The frequency of premalignant and malignant lesions increased with age (p<0.001). There was no statistical relationship between malignancy and gender (p=0.619). Conclusion: Most conjunctival masses in this series were benign, with nevi being the most common. The most common premalignant and malignant lesions were intraepithelial neoplasia and squamous cell carcinoma, respectively. Malignant conjunctival lesions were more common in older patients. © 2023 College of Physicians and Surgeons Pakistan. All rights reserved.

    Factors Predicting Response in Breast Cancer Receiving Neoadjuvant Therapy and the Role of Ki67 Labeling Index
    (College of Physicians and Surgeons Pakistan, 2023) Ekinci F.; Uzun M.; Demir B.; Unek I.T.; Erdogan A.P.
    Objective: To determine the predictive value of Ki67 on pathological complete response (pCR) of breast and axilla regions in breast cancer (BC) patients receiving neoadjuvant therapy (NAT). Study Design: Descriptive study. Place and Duration of the Study: Departments of Medical Oncology, Sirnak State Hospital, Aydin State Hospital, Manisa Celal Bayar University, and Dokuz Eylul University, from November 2010 to July 2022. Methodology: PCR and various histopathological parameters were evaluated for BC patients receiving NAT. The Youden Index method was used to find the cut-off value for the Ki67 variable according to the receiver operating characteristic (ROC) curve. This value was obtained as 77.5. Breast and axillary responses were individually evaluated to assess response to NAT. Univariate and multivariate logistic regression analysis were used to predict both breast and axillary pCR. Results: A total number of 280 females receiving NAT for BC were included in the study. Multivariate analysis for breast pCR to NAT showed that Ki67 index (>77.5 vs <77.5, p=0.047) was statistically significant marker. While Ki67 index was significant for breast pCR in both univariate and multivariate analyses, the same was not observed on axillary response (p=0.387). Conclusion: High Ki67 level was significantly associated with breast pCR in BC patients receiving NAT, but a similar effect was not observed on axillary pCR. These findings suggest that breast and axilla tissues have a biological differences in treatment responses. © 2023 College of Physicians and Surgeons Pakistan. All rights reserved.

    (College of Physicians and Surgeons Pakistan, 2023) Acar O.; Ayhan M.; Demir B.; Ekinci F.; Aytac A.; Erdogan A.P.
    Objective: To investigate the effect of the haemoglobin, albumin, lymphocyte, and platelet (HALP) score (Haemoglobin, Albumin, Lymphocyte, Platelet count) on survival as a new prognostic factor in metastatic bladder cancer. Study Design: Descriptive study. Place and Duration of the Study: Department of Medical Oncology, Celal Bayar University, Manisa, Turkey, and Adnan Menderes University, Aydin, Turkey, from 2010 to 2020. Methodology: The medical charts of patients with metastatic bladder cancer were reviewed retrospectively. Prognostic value of the HALP score as a marker of overall survival was examined through a receiver operating characteristic (ROC) curve analysis. Results: The cut-off value for the HALP score in the ROC curve analysis was 29. The median overall survival (OS) was 19 months when the HALP score was less than 29, and the median OS was 40 months when the HALP score was 29 or greater, and this finding was statistically significant (p = 0.003). Conclusion: The HALP score is closely related to prognosis in metastatic bladder cancer. A high HALP score is associated with better survival outcomes. © 2023 College of Physicians and Surgeons Pakistan. All rights reserved.
