The prostate specific antigen (PSA) is the best marker of the prostate cancer today although not very specific of this pathology. The dynamic interpretation of this marker always has to prevail over that of overtaking a threshold. With the lack of residual cancer, PSA becomes undetectable by the first month after total prostatectomy: less than 0.1 microg/L. The type of diminution mono- or biphasic of the marker depends on the chronology of the takings. Faced with residual cancer, PSA either does not become undetectable or increases after an initial undetectable period. A recurrence is defined by a value of PSA higher than 0.2 microg/L and confirmed on two successive assays. The time of appearance of the recurrence and the PSA doubling time after total prostatectomy have, with the initial clinical stage and the Gleason score, a diagnostic value on the nature of the site of recurrence, local or metastatic.

The analysis of circulating tumour DNA (ctDNA) through minimally invasive liquid biopsies is promising for early multi-cancer detection and monitoring minimal residual disease. Most existing methods focus on targeted deep sequencing, but few integrate multiple data modalities. Here, we develop a methodology for ctDNA detection using deep (80x) whole-genome TET-Assisted Pyridine Borane Sequencing (TAPS), a less destructive approach than bisulphite sequencing, which permits the simultaneous analysis of genomic and methylomic data.

Background: The peri-operative period may create a biological environment conducive to cancer cell survival and dissemination. Microscopic residual tumours (micrometastases) can be dislodged even with excellent surgical technique. At the same time, the stress response from surgery can temporarily impair immune function and activate inflammatory processes, increasing the risk of tumour proliferation.

Allogeneic hematopoietic stem cell transplantation (alloHSCT) remains an option for young and fit chronic lymphocytic leukaemia (CLL) patients with high-risk disease features. However, allotransplanted patients are generally excluded from clinical trials, making data regarding the use of venetoclax after alloHSCT extremely rare. We report data from 7 CLL patients who received venetoclax after alloHSCT among 53 Italian centers.

Over the past five years, circulating tumor DNA (ctDNA) testing has emerged as a game-changer in cancer research, serving as a less invasive and highly sensitive method to monitor tumor dynamics. CtDNA testing has a wide range of potential applications in breast cancer (BC) management, including diagnosis, monitoring treatment responses, identifying resistance mutations, predicting prognosis, and detecting future relapses. In this review, we focus on the prognostic and predictive value of ctDNA testing for BC in both neoadjuvant and adjuvant settings.

Despite adjuvant treatment with endocrine therapies, estrogen receptor-positive (ER+) breast cancers recur in a significant proportion of patients. Recurrences are attributable to clinically undetectable endocrine-tolerant persister cancer cells that retain tumor-forming potential. Therefore, strategies targeting such persister cells may prevent recurrent disease.
