Abstract

Percutaneous large core biopsy of the breast with a 14-gauge needle, supported by sonographic and mammographic procedures, shows a high degree of safety during the collection for benign and malignant lesions. All malignant diagnoses (B 5) with a portion of 44% (267/604) were confirmed surgically, whereby the typing with 79% and grading with 58% were congruent. In 3.3% (20/604), there was uncertainty (B 3 and B 4), with the necessity for further clarification by open biopsy. This was supported by the fact that in 10/16 operated cases carcinoma was found. In the B 2-category, with a portion of nearly 44% (264/604), four cases of cancer were verified--not due to a wrongly negative histology but to non-representative material. In 8.8% (53/604), a questionable representative histology (B 1) occurred, but no cancer was found after surgical intervention (n=7). The indication for surgery is not only the punch biopsy result, but additionally negative histology and suspect or malignant clinical findings.

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.
