We retrospectively analyzed the outcome of 67 patients with breast (n=24), ovarian (n=11) or testicular cancer (n=32) treated for relapse after high-dose chemotherapy (HDC) and peripheral blood stem cell (PBSC) transplantation. Treatment, survival and toxicity were analyzed. Patients with breast, ovarian or testicular cancer received a mean of 5.9 (range 1-24), 5.1 (1-13) and 4.6 (1-13) regimens for relapse after HDC. Overall response at the end of the observation period was 20.8% for patients with breast cancer (three complete (CR) and two partial responses (PR)), 45.5% (one CR, four PR) for ovarian and 9.4% (three PR) for testicular cancer patients. The mean overall-survival (OAS) from first relapse was 28 (range 3-44), 17 (2-24) and 10 (1-28) months, respectively. Leukocytopenia grade 3/4 occurred in 27-63% of patients, and thrombocytopenia grade 3/4 was observed in 58-88%, respectively. Nonhematological grade 3/4 toxicities were below 20%. In conclusion, patients with relapse after HDC usually have a poor outcome but long-term survivors are observed. Hematological toxicity is common, while other severe side effects are less frequent.

Background: Kentucky is within the top five leading states for breast mortality nationwide. This study investigates the association between neighborhood socioeconomic disadvantage and breast cancer outcomes, including surgical treatment, radiation therapy, chemotherapy, and survival, and how associations vary by race and ethnicity in Kentucky.
Methods: We conducted a retrospective cohort analysis using data from the Kentucky Cancer Registry (KCR) for breast cancer patients diagnosed between 2010 and 2017, with follow-up through December 31, 2022.
External Validation of a 5-Factor Risk Model for Breast Cancer-Related Lymphedema.

Importance: Secondary lymphedema is a common, harmful side effect of breast cancer treatment. Robust risk models that are externally validated are needed to facilitate clinical translation. A published risk model used 5 accessible clinical factors to predict the development of breast cancer-related lymphedema; this model included a patient's mammographic breast density as a novel predictive factor.

Objective: Despite the identification of various prognostic factors for anaplastic thyroid carcinoma (ATC) patients over the years, a precise prognostic tool for these patients is still lacking. This study aimed to develop and validate a prognostic model for predicting survival outcomes for ATC patients using random survival forests (RSF), a machine learning algorithm.
Methods: A total of 1222 ATC patients were extracted from the Surveillance, Epidemiology, and End Results (SEER) database and randomly divided into a training set of 855 patients and a validation set of 367 patients.

Deciphering the most promising strategy for the evolution of cancer patient management remains a multifaceted, challenging affair to date. Additionally, such approaches often lead to microbial infections as side effects, probably due to the compromised immunity of the patients undergoing such treatment. Distinctly, this work delineates a rational combinatorial strategy harnessing stereogenic harmony in the diphenylalanine fragment, tethering it to an amphiphile 12-hydroxy-lauric acid at the N-terminus (compounds -) such that a potential therapeutic could be extracted out from the series.
