Tumor-infiltrating lymphocytes (TILs) have emerged as a prognostic marker in endometrial cancer (EC). However, the role of TILs in EC with distinct histology grades and molecular types (such as mismatch repair [MMR] deficiency) has not yet been made clear. We retrospectively included 237 patients with primary EC who underwent a standard staging operation of laparoscopic or laparotomy total hysterectomy and bilateral salpingo-oophorectomy for analyses. An independent pathologist who was blind to the study patients’ information reviewed the pathologic slides to assess TILs according to the method introduced by the International Immuno-Oncology Biomarkers Working Group in 2017. The outcomes of interest included both progression-free survival (PFS) and overall survival (OS). The Kaplan–Meier method was used to determine the curves of PFS and OS according to TILs, and also in the relevant subgroups (low-grade vs. high-grade, MMR-proficient vs. MMR-deficient). After a median follow-up duration of 1.82 years, 18 patients had experienced either disease progression or death. Overall, TILs (+) were not associated with PFS or OS. We did observe, however, that TILs (+) were associated with a better PFS (p = 0.045) in patients with high-grade EC, but not in those with low-grade tumors (p = 0.733). The effect of TILs on PFS was not observed in patients with MMR-proficient (p = 0.347) or MMR-deficient (p = 0.168) EC. TILs were associated with a better PFS in patients with high-grade EC. Our results suggest that TILs may be a potential prognostic marker in these patients.

Hepatocellular carcinoma (HCC) with cardiac metastasis represents a group of rarity and poor prognosis. Few case reports have described this patient entity, and it remains unclear regarding the optimal treatment and predicted outcome for these patients. In our case, we represented a 67-year-old female patient with presentations of dyspnea and heart murmur, which conducted to the diagnosis of advanced HCC with isolated right ventricular metastasis. Because of multiple comorbidities regarding cardiac and pulmonary systems, she received best supportive care and survived 2 months after initial diagnosis. A systemic literature review of 80 published cases (including our patient) since the 1950s was also performed from PubMed, and the data were gathered from the medical record and literature reviews. In our review, patients with advanced HCC and cardiac metastasis involved the right heart mainly with a predomi
