Skin malignant melanoma (MM) is one of the most frequent and aggressive neoplasia worldwide. Its associated high mortality rates are mostly due to its metastases, while diagnosis and treatment of MM in its early stages is of favorable prognostic. Even skin superficial MMs at incipient local stages can already present with lymph node invasion and distant metastases. Therefore, knowledge of the controllable risk factors and pathogenic mechanisms of MM development, spreading, and metastatic pattern, as well as early diagnosis, are essential to decrease the high mortality rates associated with cutaneous malignant melanoma. Genetic factors are incriminated, although lifetime-acquired genetic mutations appear to be even more frequently involved in the development of MM. Skin melanocytes divide only twice per year and have time to accumulate genetic mutations as a consequence of environmental aggressive factors, such as UV exposure. In the search for more promising therapies, matrix metalloproteinases have become of significant interest, such as MMP-1, MMP-2, MMP-9, and MMP-13, which have been linked to more aggressive forms of cancer and earlier metastases. Therefore, the development of specific synthetic inhibitors of MMP secretion or activity could represent a more promising and effective approach to the personalized treatment of MM patients.

Background: Breast cancer still represents the most commonly diagnosed cancer among women, accounting for 12.5% of all new annual cancer cases worldwide. In Romania in 2020, breast cancer was the most common, with a share of new cases of 26.9%, far behind the rates of colon cancer (11.8%) and cervix cancer (7.5%). The aim of this study is to reveal five years of experience in treating breast cancer at the Surgical Clinic of the Colentina Hospital in Bucharest, Romania. Methods: Retrospective analysis, including 68 patients admitted to our clinic between January 2019 and December 2023 undergoing modified radical mastectomy, sectorectomy, or subcutaneous mastectomy. Results: Madden-modified radical mastectomy with total excision of the axillary lymph nodes accounted for 77.94% of surgeries, with a complication rate of 13.2%, represented by lymphedema of the ipsilateral arm and prepectoral seroma. Conclusions: Continuous innovation regarding early diagnosis and treatment methods in our surgical clinic will, hopefully, contribute to improving the outcomes of our patients.
