The hospital care of patients with cancer: a retrospective analysis of the characteristics of their hospital stay in comparison with other medical conditions.

PURPOSE: Hospital admission is a frequent occurrence among patients with cancer, and a significant proportion of patients admitted to medical units have cancer. Their hospital stay has features that may be different compared with patients without cancer. We performed a retrospective analysis of the characteristics of patients with cancer admitted for medical conditions. PATIENTS AND METHODS: We studied the administrative data of patients with solid cancer admitted to the medical department of a large referral hospital over a 12-month period and compared them with those of patients without cancer. RESULTS: Seven thousand eight hundred two consecutive admissions were analysed, of which 1099 (14.1%) had a principal or associated diagnosis of cancer. Admissions were distributed across 12 units, with 44% concentrated in the medical oncology unit and 56% in other units. Patients with cancer were more frequently men and were younger than patients without cancer. Admission less frequently involved the emergency department (ED), while discharge was more frequently assisted. The in-hospital death rate was higher, as was the readmission rate. Length of stay was longer (11.3 days vs. 9.8 days; p < 0.0001). Patients with cancer admitted to the medical oncology unit used the ED even less, and their length of stay was shorter than that of patients with cancer admitted in other units. CONCLUSIONS: The in-hospital pathway of patients with cancer displays specific issues and adds complexity to hospital stay of patients with medical conditions. The medical oncology unit plays a role in reducing ED use and in providing efficient care. The evidence gathered should help in shaping new models of care and in improving adequate clinical competencies.

Expression levels of circulating miRNAs as biomarkers during multimodal treatment of rectal cancer - TiMiSNAR-mirna: a substudy of the TiMiSNAR Trial (NCT03962088).

BACKGROUND: Neoadjuvant chemoradiotherapy followed by surgery is the mainstay treatment for locally advanced rectal cancer, leading to significant decrease in tumor size (downsizing) and a shift towards earlier disease stage (downstaging). Extensive histopathological work-up of the tumor specimen after surgery including tumor regression grading and lymph node status helped to visualize individual tumor sensitivity to chemoradiotherapy, retrospectively. As the response to neoadjuvant chemoradiotherapy is heterogeneous, however, valid biomarkers are needed to monitor tumor response. A relevant number of studies aimed to identify molecular markers retrieved from tumor tissue while the relevance of blood-based biomarkers is less stringent assessed. MicroRNAs are currently under investigation to serve as blood-based biomarkers. To date, no screening approach to identify relevant miRNAs as biomarkers in blood of patients with rectal cancer was undertaken. The aim of the study is to investigate the role of circulating miRNAs as biomarkers in those patients included in the TiMiSNAR Trial (NCT03465982). This is a biomolecular substudy of TiMiSNAR Trial (NCT03962088). METHODS: All included patients in the TiMiSNAR Trial are supposed to undergo blood collection at the time of diagnosis, after neoadjuvant treatment, after 1 month from surgery, and after adjuvant chemotherapy whenever indicated. DISCUSSION: TiMiSNAR-MIRNA will evaluate the association of variation between preneoadjuvant and postneoadjuvant expression levels of miRNA with pathological complete response. Moreover, the study will evaluate the role of liquid biopsies in the monitoring of treatment, correlate changes in expression levels of miRNA following complete surgical resection with disease-free survival, and evaluate the relation between changes in miRNA during surveillance and tumor relapse.

Standard (8 weeks) vs long (12 weeks) timing to minimally-invasive surgery after NeoAdjuvant Chemoradiotherapy for rectal cancer: a multicenter randomized controlled parallel group trial (TiMiSNAR).

BACKGROUND: The optimal timing of surgery in relation to chemoradiation is still controversial. Retrospective analysis has demonstrated in the recent decades that the regression of adenocarcinoma can be slow and not complete until after several months. More recently, increasing pathologic Complete Response rates have been demonstrated to be correlated with longer time interval. The purpose of the trial is to demonstrate if delayed timing of surgery after neoadjuvant chemoradiotherapy actually affects pathologic Complete Response and reflects on disease-free survival and overall survival rather than standard timing. METHODS: The trial is a multicenter, prospective, randomized controlled, unblinded, parallel-group trial comparing standard and delayed surgery after neoadjuvant chemoradiotherapy for the curative treatment of rectal cancer. Three-hundred and forty patients will be randomized on an equal basis to either robotic-assisted/standard laparoscopic rectal cancer surgery after 8 weeks or robotic-assisted/standard laparoscopic rectal cancer surgery after 12 weeks. DISCUSSION: To date, it is well-know that pathologic Complete Response is associated with excellent prognosis and an overall survival of 90%. In the Lyon trial the rate of pCR or near pathologic Complete Response increased from 10.3 to 26% and in retrospective studies the increase rate was about 23-30%. These results may be explained on the relationship between radiation therapy and tumor regression: DNA damage occurs during irradiation, but cellular lysis occurs within the next weeks. Study results, whether confirmed that performing surgery after 12 weeks from neoadjuvant treatment is advantageous from a technical and oncological point of view, may change the current pathway of the treatment in those patient suffering from rectal cancer.

Eribulin in cutaneous breast cancer metastasis treatment: clinical activity and symptom control.

AIM: This observational study evaluated the behavior and outcome of cutaneous breast cancer metastasis treated with eribulin. PATIENTS & METHODS: From November 2012 to January 2013, oncologists completed a database with patient, tumor and treatment characteristics from 14 Italian cancer centers. Skin lesions were assessed by Response Evaluation Criteria In Solid Tumors and cutaneous symptoms by present/absent criteria. RESULTS: A total of 23 metastatic breast cancer patients with skin metastasis who were treated with eribulin were analyzed. After treatment, 43% of patients exhibited a partial response, 35% stable disease and 22% progressive disease. Regarding only the skin response, 26% obtained a complete response, 22% a partial response, 39% stable disease and 13% progressive disease. We found an improvement in symptoms, infiltration and ulceration. With a median follow-up of 6 months, median progression-free survival was 4.3 months and median overall survival was 9.1 months. CONCLUSION: The response rate of skin metastasis to eribulin treatment was coherent with systemic responses. The good clinical response in most patients reflected symptom improvement.

Transhepatic arterial chemoembolization with oxaliplatin-eluting microspheres (OEM-TACE) for unresectable hepatic tumors.

BACKGROUND: While conventional transhepatic arterial chemoembolization (TACE) is accepted worldwide as an effective treatment for patients with unresectable hepatocellular carcinoma (HCC), its use in other hepatic tumors is not supported by randomized studies. Preliminary results have shown that new drug-eluting microspheres (DEM) seem to optimize TACE procedures. The aim of this study was to evaluate the capability of HepaSphere to load oxaliplatin and their pharmacokinetic outcome. The feasibility and safety of treatment with oxaliplatin-eluting microspheres (OEM-TACE) was also evaluated in patients with unresectable liver metastasis of colorectal cancer and unresectable intrahepatic cholangiocarcinoma. PATIENTS AND METHODS: An inductively coupled plasma mass spectrometer (ICP-MS) was used to quantify the oxaliplatin bound to microspheres and the oxaliplatin in liver biopsies. Fifteen patients (8 with colorectal carcinoma liver metastases, 7 with intrahepatic cholangiocarcinoma) were treated with 27 sessions of OEM-TACE. RESULTS: The data suggested that the microspheres can bind oxaliplatin entirely. The pharmacokinetic parameters were significantly different between the OEM-TACE patients and a control group of patients treated with oxaliplatin chemotherapy. The mean oxaliplatin concentration within the tumor was twenty-times higher than the extratumoral liver concentration in the OEM-TACE patients. According to response evaluating criteria in solid tumors (RECIST), stable disease was observed in 8 out of the 15 patients (53.3%), a partial response in 2 (13.3%) and intrahepatic or extrahepatic tumor progression in 5 out of the 15 patients (33.3%). No major adverse event (AE G3/4) occurred. CONCLUSION: TACE with oxaliplatin-loaded microspheres is a safe and feasible treatment without major adverse events and with a favorable pharmacokinetic profile.
