Consistent Response on Challenge and Rechallenge of Liposomal Irinotecan in a Patient with Metastatic Pancreatic Adenocarcinoma Previously Treated with Gemcitabine plus Nab-Paclitaxel: A Case Report

Approximately 80% of pancreatic cancer is diagnosed at an advanced stage, due to lack of or vague symptoms when the cancer is still localized, leading to a high mortality rate. Known risk factors for developing pancreatic cancer are family history, obesity, type 2 diabetes, and alcohol and tobacco use. There has been a remarkable development in diagnosis modalities and molecular testing, but early detection is still infrequent. The majority of clinical trials have not shown significant efficacy in pancreatic cancer, and treatment strategy remains limited. Additional prognostic factors should be highlighted to obtain appropriate treatment options, including precision medicine, and improve survival outcomes. After the PRODIGE study in 2011 and the MPAC trial in 2013, a new drug (liposomal irinotecan; Onivyde ®) appeared in the strategy, especially after failure of gemcitabine-based treatment. In 2016, the NAPOLI-1 trial showed evidence of the efficacy of the liposomal irinotecan combination (liposomal irinotecan +5-fluorouracile + folinic acid); now, it is considered the standard treatment for relapsing patients. Since NAPOLI-1, real-world data have provided similar results. Herein, we report the story of a 61-year-old woman who was treated with liposomal irinotecan combination (nal-IRI/5-FU/LV) for 8 months with good surgical response, but treatment was discontinued due to economic burden. After the start of treatment (or 1? cycle of liposomal irinotecan treatment), the patient was in a better condition. The liver metastases had disappeared. The combination with liposomal irinotecan was re-administered with patient’s approval. Upon rechallenge with the liposomal irinotecan combination, she showed a partial response, and the treatment was given for 7 months. In this report, we tried to identify the prognostic factors leading to the efficacy of the liposomal irinotecan combination.

Pancreatic Cancer and Primary Sjögren’s Syndrome: A Case Report

Primary Sjögren syndrome (SS) is a chronic inflammatory systemic autoimmune disease with a high risk of malignancy development, namely, lymphoproliferative neoplasms. Few studies also reported a high risk of solid cancers; however, the coexistence of primary SS and pancreatic cancer has been rarely described. In this paper, we aim to describe a case of a 59-year-old woman who was an active smoker with sicca symptoms and symmetrical polyarthritis and was diagnosed with primary SS two years before the development of metastatic pancreatic adenocarcinoma. Despite institution of chemotherapy, the patient succumbed to the malignancy. Besides that, we explore the link between primary SS and solid cancers including the main predictors of malignancy and the role of primary SS as a paraneoplastic syndrome. Patients with primary SS should be closely monitored for malignancy, not only for hematological cancer, but also for solid tumors. Further research is necessary to understand which are the predictors of cancer proliferation in primary SS patients.

An unusual presentation of very early onset metastatic pancreatic adenocarcinoma in a young man: case report

Pancreatic ductal adenocarcinoma (PDAC) is rare below 45 years of age and usually presents with constitutional symptoms, pain and jaundice. A 25 year old man, non-smoker, non-alcoholic presented to us with a lump in central upper abdomen of 1 month duration. Abdominal examination revealed a hard epigastric mass of size 7×10 cm. There were no other associated symptoms and no history of any similar illnesses in the family members. All laboratory parameters were within normal limits. Computed tomography showed a heterogeneous mass of size 7×13×15 cm arising from the head and neck of pancreas abutting the anterior abdominal wall with multiple abdominal and pelvic peritoneal deposits. Ultrasound guided core needle biopsy suggested PDAC. Hence, a diagnosis of very early onset metastatic PDAC was rendered and the patient was referred for palliative chemotherapy. PDAC below 45 years of age is known as very early onset PDAC. It is usually associated with family history of PDAC and known risk factors. This case was unique because of absence of the characteristic clinical features and known risk factors, early onset of occurrence and negative family history, which led to a diagnostic dilemma.
