Multiple primary malignancies in patients with renal cell carcinoma: a national population-based cohort study.

Objective: To determine the possibly greater occurrence of multiple malignancies in patients with renal cell carcinoma (RCC).

Patients And Methods: In the 7-year period 1987-93, all 1425 patients aged 15-70 years with registered histopathologically verified RCC in Norway were included in the study. All clinical and histopathology reports were checked manually, to verify the registered diagnosis and to ensure that no tumour was a metastasis from another.

Lung cancer surgery: the first 60 days. A population-based study.

Objective: The postoperative mortality following lung cancer surgery is relatively high. The purpose of the present study was to identify preoperative risk factors as well as fatal complications in 27 Norwegian hospitals.

Methods: In Norway, all clinical and pathologic departments submit reports on cancer patients to the Cancer Registry of Norway.

[Breast-conserving surgery and sentinel node procedure in Norway, 1993-2001].

Background: The aim of the present study is to describe the development in the use of breast-conserving surgery and sentinel node procedures in Norway from 1993 to 2001, with special emphasis on geographical variations and possible relationships with the mammography screening programme.

Material And Methods: The Cancer Registry of Norway registers diagnosis and treatment of all cases of cancer in Norway. All women diagnosed with breast cancer in the period 1993-2001 who received surgical treatment were included in the study except those with distant metastases at diagnosis.

Results of pulmonary resection for lung cancer in Norway, patients older than 70 years.

Objective: Surgical resection for lung cancer is the mainstay of curative treatment, but studies regarding postoperative results and long term outcome in the elderly have differed. The purpose of the present study was to assess the early and long-term results of surgical resection in patients more than 70 years of age.

Methods: In Norway all clinical and pathologic departments submit reports on cancer patients to the Cancer Registry of Norway.
