Abstract

The diagnosis of chronic hepatitis (CH) should include the information on CH etiology, the presence or absence of CH activity as well as its morphological characteristics. CH may be of a viral etiology (the type of the virus should be mentioned in the diagnosis), autoimmune, drug-induced and alcoholic. The etiology can be established by means of the clinicomorphological analysis using immunological and immunohistochemical techniques. Sometimes it is possible to do so after routine staining of biopsies. Portal, lobular and periportal hepatitis are distinguished morphologically. Instead of the indefinite term chronic persisting hepatitis it is recommended to recognize active and non-active hepatitis.

Non-radical diagnostic biopsies do not negatively influence melanoma patient survival.

BACKGROUND: In fair-skinned Caucasian populations both the incidence and mortality rates of cutaneous melanoma have been increasing over the past decades. With adjuvant therapies still being under investigation, early detection is the only way to improve melanoma patient survival. The influence of incisional biopsies on melanoma patient survival has been discussed for many years. This study investigates both the influence of diagnostic biopsy type and the presence of residual tumor cells in the re-excision specimen on disease free and overall survival. METHODS: After (partial) removal of a pigmented skin lesion 471 patients were diagnosed with stage I/II melanoma and underwent re-excision and a sentinel node biopsy. All patients were followed prospectively, mean follow up >5 years. Patients were divided according to their diagnostic biopsy type (wide excision biopsy, narrow excision biopsy, excision biopsy with positive margins and incisional biopsy) and the presence of residual tumor cells in their re-excision specimen. Survival analysis was done using Cox's proportional hazard model adjusted for eight important confounders of melanoma patient survival. RESULTS: The diagnostic biopsy was wide in 279 patients, narrow in 109 patients, 52 patients underwent an excision biopsy with positive margins and 31 patients an incisional biopsy. In 41 patients residual tumor cells were present in the re-excision specimen. Both the diagnostic biopsy type and the presence of tumor cells in the re-excision specimen did not influence disease free and overall survival of melanoma patients. CONCLUSIONS: Non-radical diagnostic biopsies do not negatively influence melanoma patient survival.
