“…As for histological types, many reports indicated that the frequency of adenocarcinoma and SCLC was high [4,[27][28][29], although differences in histology did not affect the treatment of pancreatic metastases. Although extremely rare, there have been reports of pancreatic metastasis in patients with lung squamous cell carcinoma [20,21,30], but none of our patients had pancreatic metastasis from squamous cell carcinoma. This might be dependent on the results of the study sample size.…”

Introduction: Pancreatic metastasis of lung cancer is rare, but the narrowing or obstruction of the biliary tract from pancreatic metastases limits the choice of antitumour agents. Lung cancer patients with pancreatic metastasis often have metastasis of other organs. For these patients, however, no studies have been conducted to evaluate distant metastasis sites as metastasis patterns. This study aims to assess whether these patients have specific metastasis patterns at the time of diagnosis of lung cancer. Material and methods: Data were collected from consecutive lung cancer patients with pancreatic metastasis between April 2012 and March 2022. Metastatic patterns were analysed using cluster analysis in patients with lung cancer. Results: During the study period, 33 (2.0%) of 1659 patients were diagnosed as having pancreatic metastasis. Of the 33 patients, 28 (84.8%) were male. Eighteen, 14, and one patient had small cell lung cancer (SCLC), lung adenocarcinoma, and large cell neuroendocrine carcinoma, respectively. They were divided into 3 groups by cluster analysis. A statistically significant difference in metastasis frequency was confirmed among these 3 groups (χ 2 test, p = 0.001). Conclusions: In lung cancer patients with pancreatic metastasis, knowledge of the metastatic patterns might be useful for clinical practice in the foreseeable future because it enables more efficient detection of metastatic disease through imaging, and more effective treatment at predicted metastatic sites.

“…18F-fluorodeoxyglucose uptake in pancreatic lesions was confirmed in patients who could perform FDG-PET. Then, based on images of pathologically-confirmed pancreatic metastasis from lung cancer [16][17][18][19][20][21][22][23][24][25][26], a diagnosis was made in the following conditions:…”

“…CT and MRI may not be contributory in differentiating metastases from primary adenocarcinoma, or in hyperenhancing lesions, neuroendocrine tumors[ 105 ]. FDG-PET/CT found abnormal pancreatic accumulations in 1.6%-2.3% of lung cancer cases, discovering metastases from adenocarcinoma and small and large cell lung cancer as small as 6 mm[ 111 ].…”

Malignant biliary obstruction due to metastatic non-hepato-pancreato-biliary cancer

Malignant biliary obstruction generally results from primary malignancies of the pancreatic head, bile duct, gallbladder, liver, and ampulla of Vater. Metastatic lesions from other primaries to these organs or nearby lymph nodes are rarer causes of biliary obstruction. The most common primaries include renal cancer, lung cancer, gastric cancer, colorectal cancer, breast cancer, lymphoma, and melanoma. They may be difficult to differentiate from primary hepato-pancreato-biliary cancer based on imaging studies, or even on biopsy. There is also no consensus on the optimal method of treatment, including the feasibility and effectiveness of endoscopic intervention or surgery. A thorough review of the literature on pancreato-biliary metastases and malignant biliary obstruction due to metastatic non-hepato-pancreato-biliary cancer is presented. The diagnostic modality and clinical characteristics may differ significantly depending on the type of primary cancer. Different primaries also cause malignant biliary obstruction in different ways, including direct invasion, pancreatic or biliary metastasis, hilar lymph node metastasis, liver metastasis, and peritoneal carcinomatosis. Metastasectomy may hold promise for some types of pancreato-biliary metastases. This review aims to elucidate the current knowledge in this area, which has received sparse attention in the past. The aging population, advances in diagnostic imaging, and improved treatment options may lead to an increase in these rare occurrences going forward.

Squamous cell carcinoma of the pancreas with a pancreatic intraductal papillary mucinous neoplasm: a case report

Squamous cell carcinoma (SCC) of the pancreas is very rare. No reports have described SCC accompanied by intraductal papillary mucinous neoplasm (IPMN) of the pancreas. This report presents the first known case of SCC with IPMN of the pancreas in a 71-year-old man, with a focus on radiologic findings. Here, the imaging features of SCC with IPMN of the pancreas were similar to those of IPMN of the pancreas with high-risk stigmata features.
