Impact of the Multidisciplinary Cancer Team on the Diagnostic and Therapeutic Care Pathway of Early Breast Cancer Patients and Perception of Team Members: The Experience of a Cancer Centre in Italy.

Literature on the role of multidisciplinary team (MDT) in cancer is still controversial. We aimed to investigate MDT impact on a panel of indicators in breast cancer care in a single-center retrospective study performed in a Cancer Reference Center in Italy. We analysed the diagnostic and therapeutic care pathway (DTCP) of 266 early breast cancer patients managed by our MDT during 2019-2020. Process indicators reflecting the change of the diagnostic and therapeutic care pathways occurred after the MDT discussion were computed. Further, the performance of some quality care indicators in breast cancer care since the establishment of the MDT activity and the breast cancer MDT members' perceptions were also investigated. According to our study, the MDT approach improves breast cancer management by increasing the completion of staging and by encouraging neo-adjuvant treatment and an appropriate and faster surgery. In MDT members' perspective it also improves decision-making and training and creates a positive work environment. Globally, our study encourages MDT rollout in breast cancer care. However, to enhance the reliability and comparability of the results of studies investigating MDT effectiveness in clinical practice, shared guidelines on its operationalisation are strongly desirable.

Long-term infusional systems: complications in cancer patients.

Long-term central vein catheters have found clinical application in different fields of medicine and particularly in oncology. In fact, the continuous infusion of some drugs has become the standard treatment in a wide variety of cancers, but central vein catheters are not without risks. The authors report their experience with central vein catheters. From January 1,1998, to December 31, 1999, 98 central vein catheters were placed in neoplastic patients. Seventy-seven (78.6%) Groshong and 16 (16.3%) Port-a-cath catheters were used. The central vein catheters were placed under local anesthesia. Before placement of the central vein catheters, the patients were checked by chest X-ray and neck ultrasonography. The procedure was performed under fluoroscopic control. The central vein catheters were flushed periodically with normal saline solution and sodium heparin. Sterile transparent adhesive dressings were used to occlude the operative site. The median follow-up of patients was 9 catheter months (range, 1-24 months). There were a few early and late clinically evident complications. The early complications were dislodgement in 5 cases (5.1%). The late complications were: fibrin sleeve in 1 case (1.1%), thrombosis in 2 cases (2.1%) and skin infection in 4 cases (4.1%). The low prevalence of major complications related to implants and management of these supports an increased use in oncology.

Preliminary clinical evaluation of free/total PSA ratio by the IMMULITE system.

The role of free (F) and complexed serum PSA is now under investigation. In the present study, we evaluated the clinical significance of F-PSA and F/Total (T) PSA ratio in a preliminary series of samples from 88 patients with prostate cancer (PC), 113 with benign prostatic disease (BPD), and 98 with non-prostatic disease (NP). We used the F-PSA and third generation T-PSA (DPC, Los Angeles, USA) chemiluminescent enzyme immunometric assays with the IMMULITE automated system. At the 10 ng/ml cutoff for T-PSA levels, we obtained a sensitivity of 83% with a specificity of 100% in NP and 80% in BPD. The addition of the F/T ratio--rather than F-PSA levels--was useful to better discriminate PC and BPD in the cases erroneously classified by T-PSA alone: 44/68 samples (65%) were correctly diagnosed. Moreover, the F/T ratio was particularly effective in the critical T-PSA range between 4.1-9.9 ng/ml; 26/40 cases (65%) were correctly evaluated. In conclusion, the F/T ratio seems to be an interesting auxiliary test to T-PSA, to be reserved for selected cases where additional diagnostic information is necessary.
