The management of adolescent females with giant cystosarcoma phylloides remains controversial. Since in this age group the overwhelming majority of these neoplasms are benign, aesthetic outcome is as important as adequate tumor resection. Traditional, treatment has been wide local excision, which may lead to substantial breast deformity. In addition, inadequate planning with improper incision placement may result in visible scarring and impair immediate or subsequent breast reconstruction. The treatment of four adolescent females with large breast masses using breast-sparing techniques is discussed.

Introduction: Although photodynamic therapy (PDT) shows considerable potential for cancer treatment due to its precise spatial control and reduced toxicity, effectively eliminating residual cells under hypoxic conditions remains challenging because of the resistance conferred by these cells.
Methods: Herein, we synthesize an amphiphilic PEGylated polyphosphoester and present a nanocarrier (NP) specifically designed for the codelivery of hydrophobic photosensitizer (chlorin e6, Ce6) and hypoxia-activated prodrugs (tirapazamine, TPZ). We investigate the antitumor effect of NP on both cellular and animal level.

Phyllodes tumor is a type of fibroepithelial neoplasm involving the breast. This tumor is rarely reported in adolescents and the elderly and has a peak incidence in middle-aged women. Histologically, phyllodes tumors are classified as benign, borderline, or malignant.

However, most tumors lack actionable alterations, restricting treatment options to cytotoxic chemotherapies for which few data-driven prioritization strategies currently exist. Here, we report an integrated computational/experimental treatment selection approach applicable for both chemotherapies and targeted agents irrespective of actionable alterations.

Background: There has been limited success of cancer immunotherapies in the treatment of ovarian cancer (OvCa) to date, largely due to the immunosuppressive tumour microenvironment (TME). Tumour-associated macrophages (TAMs) are a major component of both the primary tumour and malignant ascites, promoting tumour growth, angiogenesis, metastasis, chemotherapy resistance and immunosuppression. Differential microRNA (miRNA) profiles have been implicated in the plasticity of TAMs.

Adenoid cystic carcinoma (AdCC) of the breast is a rare histological subtype of breast cancer, which usually has a low propensity for metastasis and is associated with a good prognosis. AdCC metastasis to the kidney is rare, with only 29 cases reported in the literature. We report a case of a woman in her 60s with multiple right-sided large cystic-solid renal lesions after a recent diagnosis of marginal zone B-cell lymphoma.
