Introduction: Penile cancer is a rare malignancy and potentially lethal disease with an incidence of 0,6-2,1 per 100.000. Squamous cell carcinoma (SqCC) is the most commonly found penile malignancy. PD-L1 is a tumor marker that co-stimulates the receptor PD-1 to suppress T-cell- mediated antitumor immunity. Methods: This study is a retrospective cohort study with a total sampling method. The slides taken from the biopsies of seventy-six male patients from Haji Adam Malik Hospital diagnosed with penile squamous cell carcinoma who have already undergone penile biopsy were re-examined for this study, and PD-L1 levels were measured accordingly. Statistical methods were used to assess the association between PD-L1 levels and with SqCC stage. Results: A total of 76 male patients are the subjects of this study. PD-L1 positivity is identified in 25 patients with +1 intensity in 10 patients (13,2%), +2 in 7 patients (9,2) and +3 intensity in 8 patients (10,5%). There are 36 patients (47,4%) diagnosed with stage T3 SqCC, 35 patients (46,1%) with stage N2 SqCC, and 10 patients (13,2%) with stage M1 SqCC. There is significant correlation between PD-L1 expression and metastasis (p=0,022). However, there is no significant correlation between PD-L1 expression and stage N tumor (p=0,167). Conclusion: PD-L1 highly expressed in advanced stage penile SqCC (32.9%), which is associated with the high-risk clinicopathologic features and poor clinical outcomes. These findings showed a potential usage of immunotherapy in advanced penile SqCC treatment."

"At this time there is an increasing demand for an accurate pre operative staging in non small cell lung cancer. Chest Computed Tomography (CT) is one of the imaging modality of choice used for this purpose. This study evaluated the accuracy of the chest CT to determine the status of tumor and nodules in non small cell lung cancer. During the years 1998 and 1999 a descriptive prospective study of 32 patients undergoing a contact enhanced chest CT examination for non small cell lung cancer, stage I-IIIA, was conducted. Lobectomy, lu\ymph nodes dissection and postoperatice histo-pathological examination were done. CT findings were as followas a sensitivity of 100% , a specificity of 25% and an accuracy of 60% in the detection of the nodule stage were found. In 17 patients with adeno-carcinoma, the sensitivity, the specificity and the accuracy were 86.6%, 100% dan 88.2% respectively. The diagnosis of all patients was conformed histo-pathologically. Six patients with T2 dan 26 patients with T3 were detected by chest CT; the accuracy of the tumor status was 93.7% confirmed by surgical and histo-pathological examinations. It was concluded that th CT played an important role in determining the clinical stage of non small cell lung cancer. The specificity and accuracy were higher in adeno-carcinoma as compare with squamous cell carcinoma in detecting the nodal status."

Background: Cervical cancer is one of the leading causes of death related to malignancies. One of the contributing factor toward this high mortality rate is that patients are usually diagnosed at an already advanced stage. Radiotherapy can be used as a treatment for advanced cervical patients who cannot tolerate the side effects of chemotherapy. However, patients with cervical cancer show mixed responses to radiotherapy.

Objectives: This study aims to assess the association between CD8+ TILs density in advanced stage cervical cancer and its response to radiotherapy.

Methods: This is a case-control study. The study population were patients diagnosed with stage IIIB uterine cervix squamous cell carcinoma at the Department of Anatomical Pathology Faculty of Medicine University of Indonesia (FMUI)/Cipto Mangunkusumo Hospital (CMH) from January 1st, 2016 up to December 31st, 2021, who received definitive radiotherapy at the Department of Radiation Oncology FMUI/CMH, and had complete radiotherapy response data. Patients with complete response are classified as the response group and those with incomplete response are classified as the control group. Sampling is done consecutively. The data were statistically analyzed to assess the factors influencing radiation response.

Results: Forty cases of stage IIIB uterine cervix squamous cell carcinoma were selected, consisting of 20 cases with complete radiation response and 20 cases with incomplete response. The median CD8+ iTILs density in the complete response group was higher than in the incomplete response group (1099 cells/mm2vs 920,27 cells/mm2, p: 0,035). The recommended cut-off point for predicting radiotherapy response was 959,32 cells/mm2. No statistically significant relationship was found between tumor size, degree of differentiation, and keratinization on response to radiotherapy.

Conclusion: Higher CD8+ iTILs density was associated with better response to radiotherapy in stage IIIB uterine cervix squamous cell carcinoma."

Background Oral cavity and mouth cancer (including oral cavity squamous cell carcinoma (OCSCC) collectively remain the 16th most prevalent cancer in the world. Due to the tendency of advanced stage during diagnosis, the survival of OCSCC patients is abysmal. The connection of OCSCC and expressed tumor infiltrated lymphocytes (TILs) is thought to affect the survivability of the OCSCC patients, including CD8+ and other TILs. Aim To determine the expression of CD8+ and TILs in OCSCC cells and their relationship with overall survival (OS) and progression-free survival (PFS) of OCSCC patients. Methods This study is a survival analysis using retrospective cohort design on OCSCC patients who came to Cipto Mangunkusumo National General Hospital, Indonesia, from January 2017 to December 2021. The inclusion criterion of the study was OCSCC patients with histopathological diagnosis, while the exclusion criteria were patients with incomplete data or unavailability of the samples. The expression of CD8+ and TILs were measured by manual counting of cells using ImageJ® on immunohistochemistry staining. The OS and PFS were analyzed using Kaplan-Meier graph and cox-regression analysis. Result A total of 42 subjects were included in this study. The average OS was 10.83+1.268 months, while the average PFS was 9.74+1.229 months. The 2-years OS was 21.4%, while PFS was 19%. Higher CD8+ expression was related to better OS and PFS, while higher expressed TILs was related to better PFS.
