Hypertrophic pulmonary osteoarthropathy with primary lung cancer
نویسندگان
چکیده
Hypertrophic pulmonary osteoarthropathy (HPO) is a rare paraneoplastic syndrome that is frequently associated with lung cancer; however, the incidence of clinically apparent HPO is not well known. The clinical data of 6,151 patients with advanced lung cancer between January 1996 and December 2008 were retrospectively analyzed in Zhejiang Cancer Hospital (Hangzhou, China). Data pertaining to the presentation of HPO, diagnosis, treatment, pathology, follow-up and clinical course were documented. HPO was confirmed using bone scintigraphy by the identification of symmetrical, abnormally high uptake in the joints, and/or long bones with digital clubbing in the extremities as well as joint pain. The clinical characteristics were investigated based on clinical and pathological records. The patients were presenting with lung cancer for the first time and had not received treatment. Among the 6,151 lung cancer patients, 115 (1.87%) demonstrated an abnormally high uptake on bone scintigraphy and digital clubbing in the extremities combined with joint pain. A total of 109 patients received surgery or chemotherapy treatment and 92 exhibited improved symptoms. The improvement rate of HPO was lower in the non-surgery compared with the surgery patients (77.4 vs. 91.1%; P=0.049). Bone scintigraphy was repeated in 85 patients within 3-6 months, and the HPO symptoms improved in 70 patients. The present retrospective study indicated that 1.87% of patients with lung cancer showed characteristics that were identified as HPO. The majority of the patient symptoms and the bone scintigram of HPO improved as a result of treatment.

Hypertrophic pulmonary osteoarthropathy (HPO) associated with non-small cell lung cancer in a 58-year-old man was accompanied by an elevated serum level of growth hormone (GH). HPO rapidly disappeared after resection of the primary tumor and the elevation of serum GH was resolved. Immunohistochemically the tumor contained growth hormone-releasing hormone (GHRH) but not GH. These findings sugges...

Hypertrophic pulmonary osteoarthropathy (HPOA) is a syndrome defined by clubbing of the fingers and toes, arthritis and periostitis [1]. It was first described by Bamberger in 1889 and Pierre Maire in 1890 although clubbing, was recognized by Hippocrates 2500 years ago [2,3]. It is also known as Marie-Bambeger Disease. It has long been associated with Pulmonary Malignancies such as Non-Small-Ce...
متن کاملPolyarthritis and Hypertrophic Pulmonary Osteoarthropathy in a Case of Pulmonary Neoplasm
Pulmonary osteoarthropathy may occur in cancer of the lung but is rare due to short course of the disease (Shanks and Kerley, 1951). The combination of polyarthritis is even more rare. Holmes et al. (1950) reported symptomatic arthritis complicating hypertrophic osteoarthropathy in a series of seven cases and stressed the importance of this condition in the diagnosis of pulmonary neoplasm. The ...
