BACKGROUND: Cancer not only affects patients but also their caregivers. The objective of the current study was to assess the unmet needs of cancer caregivers and to identify possible predictors of their supportive care needs.METHODS: In a cross‐sectional survey, 188 dyads of patients diagnosed with lung, urological, or gastrointestinal cancer and their primary caregivers were recruited. Caregivers were asked to complete the Supportive Care Needs Survey self‐report questionnaire (for partners and caregivers); patients completed the corresponding questionnaire. Both groups provided information regarding their distress (National Comprehensive Cancer Network Distress Thermometer), anxiety, and depression (Patient Health Questionnaire‐4). Clinical characteristics were obtained from medical records.RESULTS: The mean age of the caregivers was 57.8 years. Approximately 72.3% were female. Patients had an average age of 62.5 years, with 33.0% being male. Caregivers were more distressed (P<.01) and exhibited higher anxiety scores (P<.01) compared with patients. Approximately 14.4% of caregivers reported no unmet need and 43.6% had at least 10 needs that were unmet. Main caregiver concerns were regarding health care service and information needs followed by emotional and psychological needs. To some degree, unmet needs in patients and caregivers' anxiety predicted unmet caregiver needs. Sociodemographic and clinical variables were not found to be significant predictors.CONCLUSIONS: A substantial percentage of caregivers have unmet needs for support, mainly with regard to fears concerning the patient's condition, receiving disease‐related information, and emotional support for themselves. Prediction of unmet needs in caregivers from other clinical and psychological variables was rather poor. Therefore, by means of the frequency and disparity of caregivers unmet needs, they should be systematically assessed to direct specific offers.

We developed an effective way to precisely diagnose prostate cancer using a novel prostate biopsy system that integrates pre-interventional magnetic resonance imaging with peri-interventional ultrasound for perineal navigated prostate biopsy. A total of 106 men with findings suspicious for prostate cancer (median age 66 years, prostate specific antigen 8.0 ng/ml and prostate volume 47 ml) underwent multiparametric 3 Tesla magnetic resonance imaging. Suspicious lesions were marked and data were transferred to the novel biopsy system. Using a custom-made biplane transrectal ultrasound probe mounted on a stepper we gathered 3-dimensional ultrasound data and fused them with magnetic resonance imaging data. As a result, suspicious magnetic resonance imaging lesions were superimposed over the transrectal ultrasound data. Three-dimensional biopsy planning was done, including systematic biopsies. Perineal biopsies were taken under live ultrasound guidance and the precise site of each biopsy was documented in 3 dimensions. We evaluated feasibility, safety and cancer detection. Prostate cancer was detected in 63 of 106 patients (59.4%). Magnetic resonance imaging findings correlated positively with histopathology in 71 of 103 patients (68.9%). In magnetic resonance imaging lesions marked as highly suspicious, the detection rate was 95.8% (23 of 24 cases). Lesion targeted cores had a significantly higher positivity rate than nontargeted cores. The procedural targeting error of the first 2,461 biopsy cores was 1.7 mm. Regarding adverse effects, 2 patients experienced urinary retention and 1 had a perineal hematoma. Urinary tract infections did not develop. Perineal stereotactic prostate biopsies guided by the combination of magnetic resonance imaging and ultrasound enable effective examination of suspicious magnetic resonance imaging lesions. Each biopsy core taken is documented accurately for its location in 3 dimensions, enabling magnetic resonance imaging validation and tailored treatment planning. The morbidity of the procedure was minimal.

Isolation and characterization of tumourigenic colon cancer initiating cells may help to develop novel diagnostic and therapeutic procedures.
