The frequency of cancer of the pancreas is increasing and has surpassed that of cancer of the stomach. Lesions are more common in the head of the gland than in the body and tail. Smaller tumours tend to be localized and are associated with a better prognosis. The majority of tumours are hard and demonstrate a prominent desmoplastic reaction. They present as ill-defined masses which makes their differentiation from chronic pancreatitis difficult. Duct cell adenocarcinomas constitute 75% of all cancers of the pancreas. Some of the uncommon types include giant cell carcinoma, adenosquamous carcinoma, mucinous cystadenocarcinoma and acinar cell carcinoma. The role of open biopsy in diagnosing cancer of the pancreas remains controversial. Percutaneous fine-needle aspiration cytology appears promising. The technique is safe and inexpensive but needs an experienced cytopathologist to interpret the results accurately.
胰腺癌的发病率正在上升，已经超过了胃癌。病变在胰腺头部比在体部和尾部更常见。较小的肿瘤往往局限，预后较好。大多数肿瘤质地硬，表现出明显的促纤维增生反应。它们表现为边界不清的肿块，这使得它们与慢性胰腺炎难以区分。导管细胞腺癌占胰腺癌的75%。一些不常见的类型包括巨细胞癌、腺鳞癌、黏液性囊腺癌和腺泡细胞癌。开放式活检在胰腺癌诊断中的作用仍存在争议。经皮细针穿刺细胞学检查似乎很有前景。该技术安全且廉价，但需要经验丰富的细胞病理学家准确解读结果。
