The triple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype with a high rate of distant metastasis. The tumor immunity microenvironment plays an important role, including tumor-infiltrating lymphocytes (TIL) and PD-1 (programmed cell death 1)/PD-L1 (programmed cell death-ligand 1), in promoting TNBC aggressiveness. This study aimed to determine the association of TIL and PD-L1 expression with the incidence of distant metastasis in TNBC. This study is a cross-sectional study involving TNBC subjects at Sanglah General Hospital, Denpasar, conducted in 2019. The parameters analyzed were the expression of TIL, PD-L1, and the incidence of distant metastasis. The expression of TIL was analyzed histopathologically while PD-L1 was measured with Ventana PD-L1 kit test. Subject characteristics were obtained from medical records. Data were collected and analyzed by SPSS 22.0. As many as 31 subjects with TNBC were included in this study, with 51.6% subjects with distant metastasis. The majority of subjects with distant metastasis had low TIL and low tumoral PD-L1 but high PD-L1 stromal in TIL. Perifosine cost From statistical analysis, only PD-L1 stromal in TIL expression was associated significantly with distant metastasis (p = 0.043). In conclusion, there was a significant association between PD-L1 stromal in TIL and the incidence of distant metastasis in TNBC.Salivary duct carcinoma (SDC) is a rare and highly aggressive malignancy. A 58-year-old man presented with a right-sided submandibular mass and metastatic lesions in the right supraclavicular and inferior internal jugular nodes. He underwent right submandibulectomy and right neck dissection followed by adjuvant chemoradiotherapy. However, relapse occurred in the hilar lymph node and lumbar spine. Although radiotherapy was performed, a second relapse appeared in the hilar lymph nodes and sacral bone. Immunohistochemical analysis revealed negativity for programmed death ligand-1 (PD-L1) in the primary tumor specimen. The patient then received the anti-programmed death-1 (PD-1) antibody nivolumab. His metastatic lesions were completely eliminated after 48 weeks of therapy. This case reveals that anti-PD-1 antibodies are effective even against PD-L1-negative SDC.Radiation-induced myopathy (RIM) is a rare complication occurring years after radiotherapy. RIM basically occurs within the irradiation field, but some cases have been reported to be accommodated by myopathy outside the irradiation field, and the actual extent of RIM is obscure. The presented case also showed decreased MMT scores and abnormal needle electromyography results in the muscles outside the irradiated field, and the patient was initially thought to have RIM both within and outside the irradiated field. However, while systemic postmortem muscle sampling revealed prominent myopathy in line with RIM in the irradiated muscles, only mild myogenic changes that could be explained by other causes such as age-related sarcopenia, radiculopathy, and disuse atrophy were observed in the non-irradiated muscles. The number of biopsy sites in live patients is limited due to the invasive nature of the procedure, but we were privileged to systemically evaluate the extent of myopathy through multiple muscle sampling including muscles both inside and outside of the irradiation field because this was an autopsy case. Through the presented case, we conclude that RIM is a phenomenon most probably limited to the muscles within the irradiated field, and myopathy outside the irradiation is due to other causes.We report a case of a 60-year-old male with metachronous primary malignancies, pancreatic cancer and malignant melanoma which recurred simultaneously. Both cancers were challenging to diagnose and throughout the case at different times, the presence of two active malignancies obscured the clinical picture. A bleeding gastric lesion found in the stomach 6 months after a distal pancreatectomy for pancreatic adenocarcinoma revealed metastatic melanoma, presumed secondary from a melanoma excised from the patient's back 2 years previously. During surgery intended to resect the gastric lesion, peritoneal nodularity was identified, with histology confirming metastatic pancreas cancer. This case highlights two main points of interest. Firstly it emphasises the role for consideration of a genetic predisposition in young patients with more than one primary malignancy. The man in this case was not informed of his family history as he was adopted. If he had knowledge of previous family history, he may have been able to provide information to expedite arrival at the diagnosis of a CDKN2A mutation (melanoma-pancreatic carcinoma syndrome). In addition, this case also raises the issue of the challenges we face when treating synchronous primary malignancies. The two malignancies here behaved equally aggressively and posed obstacles for treatment as there is no mutual method of carcinogenesis that could be targeted with treatment; therefore, treatment modalities had to be chosen to treat each malignancy separately. To date, studies evaluating the role for targeted therapy in the setting of CDKN2A mutations have not conclusively provided meaningful benefits to patients.Brain tumors have long been considered one of the most prevalent causes of potentially reversible cognitive impairment. An accurate underlying cause of cognitive impairment due to brain tumor needs to be evaluated pragmatically. Patterns of cognitive impairment associated with brain tumors depend mainly on their location, lateralization, pathological classification and secondary effects of the treatment, as well as the structural plasticity and diaschisis. Hence, it is not rare that lesions with different locations and histologies may manifest with a similar pattern of cognitive impairment due to the complex interplay of determinants. We herein report 3 patients with brain tumors affecting different locations and with differing histologies, who shared a similar presentation as "frontal dysexecutive syndrome" masqueraded as psychiatric conditions. Detailed examination of saccades and pursuit along with eye movements and conventional motor examinations were essential not only to diagnose brain tumor as the potential cause of cognitive impairment, but also to rule out other coexisting etiologies with completely different underlying pathological mechanisms (i.
