Skin sparing and nipple areola complex sparing subcutaneous mastectomies are both oncologically safe surgical procedures. Although autologuous breast reconstruction has been considered as a standard means of surgical approach, excellent cosmetic results have been obtained by implant based breast reconstruction. In this report, we present the result of titanium coated polypropylene mesh (Tiloop Bra; Pfm Medical, Cologne, Germany), an ultimate support material utilized in the reconstruction of a patient with breast cancer.

Breast carcinoma is a rare disease in males compared to females and papillary carcinoma of the breast is seen less than 1% of all male breast carcinomas. Solid papillary carcinoma of the breast, with transitional cell epithelium and neuroendocrine differentiation, is a rare entity. We report a 28-year-old male patient with a painless mass in the left breast due to solid papillary carcinoma while receiving anti-tuberculosis therapy. Tumor is characterized by neuroendocrine differentiation with accompanying transitional cell variant epithelium. The tumor was successfully excised. Although solid papillary carcinoma is thought to have a better prognosis than other breast carcinomas, in our patient, local and axillary recurrences were seen in one year, in contrast to reports in the literature. Inconclusion, the solid papillary carcinoma with transitional cell epithelium and neuroendocrine differentiation of breast in a male is a very rare disease. Its prognosis could be worse than reported in the literature.

Abstract With a 5-year survival of ˂ 10%, pancreatic cancer is one of the leading causes of cancer-related deaths. Given the role of the distribution of tumor-infiltrating lymphocyte (TILs) subtypes in the tumor and its microenvironment in predicting prognosis, the development of new targeted therapies based on T-cell adaptive response has gained considerable attention. This study aimed to examine the peritumoral spread of TILs and its relationship with other prognostic parameters and survival. This study included 60 patients with pancreatic cancer who had undergone surgery with follow-up between 2011 and 2021. Demographic characteristics, tumor histopathological features, peritumoral TILs counts, and intratumoral programmed cell death protein-1 (PD-1) and programmed death ligand − 1 (PD-L1) positivity were evaluated. Furthermore, overall survival and their efficacy in predicting survival according to TNM stage were analyzed. The number of cluster differentiation-3 positive (CD3 P) TILs increased with advancing pathological T stage. CD3 P and CD8 P TIL counts were higher in patients with peripancreatic fatty tissue invasion. Patients with PD-L1 positivity and higher TIL counts had better survival rates. PD-L1-negative patients with a low CD8 positive/total lymph node count (P/T) ratio had a longer survival. Moreover, patients with poorly differentiated tumors with low CD3 P/T and CD8 P/T ratios had a longer survival. The CD3 P/T and CD8 P/T ratios were compatible with the automatic and manual measurements. Age, tumor differentiation, N stage, and peritumoral TIL count and subtype, when evaluated together with the presence of PD-L1 in the tumor tissue, may have prognostic significance for survival in patients with pancreatic cancer.

Antecedentes. El uso de quimioterapia neoadyuvante (QTN) en cáncer de mama (CB) menos agresivo es controversial. Objetivo: Investigar el efecto de la quimioterapia neoadyuvante en el cáncer de mama HER2 negativo luminal B. Método. Se evaluaron retrospectivamente pacientes entre enero de 2016 y diciembre de 2021. Resultados. Se incluyeron 128 pacientes. Los valores de corte para ki67 basados en el estado de respuesta patológica completa y el estadio tumoral tras la quimioterapia neoadyuvante fueron ≤ 40% y ≤ 35%, respectivamente. Según los hallazgos de la resonancia magnética previa a la quimioterapia neoadyuvante, la mastectomía solo fue viable en 90 pacientes, pero después de la quimioterapia neoadyuvante la cirugía conservadora de la mama fue posible en 29 (32%). Además, el 68.5% se volvieron elegibles para biopsia del ganglio linfático centinela después de la quimioterapia neoadyuvante, y se evitó la disección de ganglios linfáticos axilares en 38 pacientes (31.4%). Conclusiones. En las pacientes con cáncer de mama HER2 negativo luminal B, una tasa baja de respuesta patológica completa no debe desalentar el uso de quimioterapia neoadyuvante. En especial en pacientes jóvenes con niveles altos de ki67, la quimioterapia neoadyuvante aumenta la posibilidad de una cirugía conservadora de la mama y puede evitar que las pacientes sufran disección de ganglios linfáticos axilares.

Objective:Knowing axillary lymph node (ALN) status before surgery affects decisions about treatment modalities. Therefore, reliable, noninvasive diagnostic methods are important for determining ALN metastases. We aimed to accurately evaluate the patient’s ALN status with noninvasive imaging modalities while making treatment decisions.Materials and Methods:Patients who received the axillary ultrasound (AUS), magnetic resonance imaging (MRI), or 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) imaging modalities and whose ALNs were confirmed histopathologically by fine needle aspiration cytology (FNAC), sentinel lymph node biopsy (SLNB), or ALN dissection (ALND) were included in the study.Results:The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of AUS for the detection of ALN metastases were 83%, 62%, 59.2%, 54.8%, and 79.1%, respectively. For MRI they were 86.1%, 75%, 68.5%, 51.6%, and 85.3%, respectively, and for 18F-FDG-PET/CT they were 78%, 53%, 56.2%, 51.4%, and 72.5%, respectively. ALNs were found to be metastatic in all patients who were reported positive in all three imaging modalities. ALN metastases were detected in 19 of 132 patients (false negativity, 14.3%) in whom AUS, MRI, and 18F-FDG-PET/ CT images were all reported as negative.Conclusion:In our study, we found that the diagnostic performance of MRI was slightly better than AUS and 18F-FDG-PET/CT. When we used imaging modalities together, our accuracy rate was better than when we used them alone. For accurate evaluation of axillary lymph nodes, imaging modalities should be complementary rather than competitive.
