A 67-year-old man had suffered from persistent abdominal cramping pain for six months, with radiation to the back. Adenocarcinoma of pancreatic body with celiac encasement was diagnosed. Neoadjuvant chemotherapy was given and regressive tumor size was noted. Further operation of distal pancreatectomy with celiac axis resection (DP-CAR), including transection of the left gastric artery (LGA), was performed. The middle colic artery (MCA) was utilized for reconstruction of LGA, with LGA-MCA anastomosis. Intraoperative indocyanine green (ICG) fluorescence was used to confirm the blood supply. DP-CAR is a complicated procedure for tumor involving celiac axis but would bring benefit if en bloc resection was achieved. Reconstruction of the transected vessels was important to reduce further complications. Intraoperative indocyanine green (ICG) fluorescence imaging is a feasible method of evaluating the blood supply to the stomach and liver after the DP-CAR procedure.

Gastric adenosquamous carcinoma (GASC) is an extremely rare malignancy of the stomach. It is generally diagnosed at an advanced stage and is associated with a poor prognosis. Notably, the standard treatments for GASC remain undetermined because of the condition's rarity. In this report, we present a patient diagnosed with advanced GASC with positive predictive biomarkers for immune checkpoint inhibitors (ICIs), who achieved a durable response through nivolumab monotherapy. We also review and discuss the management of GASC and possible roles of ICIs in gastric cancers.

Immune checkpoint inhibitors, including anti-programmed death receptor-1/ligand-1 drugs and anticytotoxic T lymphocyte-associated antigens, are novel drugs for the treatment of many cancers. However, they may rarely cause neurological immune-related adverse effects, including immune-related myasthenia gravis (MG). This condition leads to poorer clinical outcomes, especially when coexisting with myositis or myocarditis. We report a case of a patient with advanced cholangiocarcinoma along with a history of thymoma in whom a triad of MG, myositis, and myocarditis developed after nivolumab administration. Early recognition of neuromuscular symptoms remains critical to successful management.

Lymphoepithelioma-like cholangiocarcinoma (LEL-CC) is a rare variant of intrahepatic cholangiocarcinoma. Only a few cases of LEL-CC have been reported, and the understanding of LEL-CC remains limited. Herein, we describe a case involving a 38-year-old Asian man with hepatitis B virus infection and LEL-CC. The patient's liver tumor was incidentally discovered during routine abdominal ultrasonography without obvious clinical signs or symptoms. Dynamic magnetic resonance imaging (MRI) revealed features of hepatocellular carcinoma and he underwent laparoscopic partial hepatectomy. Histologically, the liver tumor exhibited a lymphoepithelioma-like appearance and features of cholangiocarcinoma with Epstein–Barr virus infection.

Primary signet-ring cell carcinoma of the appendix is extremely rare, and because the symptoms are vague and nonspecific, obtaining a preoperative diagnosis is difficult. It cannot be detected using imaging modalities because its radiologic features are undefined, and its appearance on both computed tomography and ultrasound images is similar to that of nontumorous appendicitis. Usually, a diagnosis is made after surgery for other diseases involving the removal of the appendix. The right hemicolectomy is suggested for invasive adenocarcinoma; however, diagnosing primary signet-ring cell carcinoma before surgery and managing tumors with adequate surgical resection remain challenging. We present a case of a large ovarian tumor with peritoneal carcinomatosis diagnosed with advanced ovarian cancer but subsequently revealed through pathology to be primary appendiceal signet-ring carcinoma. Detecting appendiceal signet-ring carcinoma warrants additional surgical management, and treating it involves chemotherapy. This rare disease should be kept in mind when encountering abdominal right lower quadrant pain and tumors to allow for a full treatment plan.

We report the case of a 68-year-old male with mechanical small bowel obstruction complicated by metastasis of nasal cavity basal cell adenocarcinoma (BCAC). The initial presentation included intermittent abdominal cramping pain and postprandial vomiting. We performed diagnostic laparoscopy under the impression of small bowel obstruction and noticed a tumor located at the terminal ileum. Tumor excision and end-to-end intestinal anastomosis were performed, and pathology reports confirmed the diagnosis of metastatic BCAC. A literature review revealed that small bowel metastatic tumors are rarely caused by BCAC, and that distant metastases of BCAC are also rare. Being aware of this rare disease may lead to an earlier correct diagnosis of small bowel obstruction due to a metastatic tumor.

Poorly differentiated neuroendocrine carcinoma of the gallbladder is an aggressive and extremely rare type of neuroendocrine tumor. The clinical presentations in most cases are nonspecific, resulting in patients being diagnosed at an advanced stage of the disease. Herein, we report our experience with the case of a 63-year-old woman with no comorbidities who underwent radical resection for a diagnosed gallbladder mass. Abdominal computed tomography scans and magnetic resonance cholangiopancreatography indicated intraluminal masses in the gallbladder with liver invasion. Histologically, the mass was composed of solid sheets of poorly differentiated carcinoma cells with hyperchromatic nuclei; a high Ki-67 index of approximately 80%. The cells were positive for chromogranin A and synaptophysin, and small-cell-type neuroendocrine carcinoma was diagnosed. Postoperatively, she underwent adjuvant chemotherapy with four cycles of cisplatin/etoposide chemotherapy and was disease-free 16 months after surgical treatment with normal hormone-specific markers.

Background: Clinical trials have demonstrated that the 21-gene assay (Oncotype DX) can predict the benefits of adjuvant chemotherapy in patients with hormone receptor-positive (HR+) and human epidermal growth factor 2-negative (HER2−) breast cancer. This study investigated the real-world utilization of this genomic test in Taiwanese patients. Materials and Methods: We compiled data on the recurrence score (RS) and clinicopathological characteristics of patients who received the 21-gene assay between August 2016 and August 2021. Survival outcomes were analyzed using the Kaplan–Meier method and log-rank test. Correlations between clinicopathological characteristics and RSs were analyzed using the Chi-square test or Fisher's exact test. Results: Of the 106 recruited patients, 34 and 72 were classified into different risk groups using conventional and Trial Assigning Individualized Options for Treatment (TAILORx)-based cutoff points, respectively. In the conventional stratification group, 61.8%, 29.4%, and 8.8% of the patients were classified into the low-risk (RS: 0–17), intermediate-risk (RS: 18–30), and high-risk (RS: 31–100) categories, respectively. In the TAILORx stratification group, 18.1%, 72.2%, and 9.7% of the patients were classified into the low-risk (RS: 0–10), intermediate-risk (RS: 11–25), and high-risk (RS: 26–100) categories, respectively. In survival analysis, recurrence-free survival did not significantly differ among discrete risk categories. The high-risk category determined using TAILORx-based cutoff points was associated with the presence of >14% Ki-67-positive cells (P = 0.004) and tumor histology Grade III (P = 0.001). Conclusion: Using the Oncotype DX assay, we classified a small proportion of our Taiwanese patients into the high-risk category; no survival difference was observed among the patients in distinct risk categories. These results suggest the clinical utility of the 21-gene assay in Taiwanese patients with early HR+/HER2−breast cancer.

Spindle cell melanoma (SCM) is a rare morphological subtype of mucosal melanoma, especially located in the lower rectal or anal region. The diagnosis of SCM is challenging because it may share some morphological and immunohistochemical features with desmoplastic melanoma or other malignant tumors. Anorectal melanoma is characterized by aggressive biological behavior, a high incidence of local recurrence and metastasis, and poor outcomes. We herein report a 56-year-old female patient with a challenging diagnosis of primary rectal SCM with a poor prognosis and review the literature.

We report a case of a perivascular epithelioid cell tumor occurring in the falciform ligament of an otherwise healthy 32-year-old woman. The mass was hypervascular with central necrosis on computed tomography (CT) and contrast-enhanced ultrasound. Our case is unique as CT and ultrasound revealed a paraumbilical vein arising from the expected location in the fissure for the falciform ligament and terminating in the superior aspect of the mass. The vascular anatomy of a recanalized paraumbilical vein, typically associated with portal hypertension, was complete with drainage of blood from the inferior aspect of the mass through the inferior epigastric veins to the femoral veins. The patient had no evidence of liver disease or portal hypertension.
