Predictive values of two frailty screening tools in older patients with solid cancer: a comparison of SAOP2 and G8

Objectives: Comprehensive Geriatric Assessment (CGA), the gold standard for detecting frailty in elderly cancer patients, is time-consuming and hard to apply in routine clinical practice. Here we compared the performance of two screening tools for frailty, G8 and SAOP2 for their accuracy in identifying vulnerable patients. Material and Methods: We tested G8 and SAOP2 in 282 patients aged 65 or older with a diagnosis of solid cancer and candidate to undergo surgical, medical and/or radiotherapy treatment. CGA, including functional and cognitive status, depression, nutrition, comorbidity, social status and quality of life was used as reference. ROC curves were used to compare two screening tools. Results: Mean patient age was 79 years and 54% were female. Colorectal and breast cancer were the most common types cancer (49% and 24%). Impaired CGA, G8, and SAOP2 were found in 62%, 89%, and 94% of the patients, respectively. SAOP2 had a better sensitivity (AUC 0.85, p<0.032) than G8 (AUC 0.79), with higher performance in breast cancer patients (AUC 0.93) and in patients aged 70-80 years (AUC 0.87). Conclusions: G8 and SAOP2 both showed good screening capacity for frailty in the cancer patient population we examined with SAOP2 showing a slightly better performance than G8

Her2 assessment using quantitative reverse transcriptase polymerase chain reaction reliably identifies Her2 overexpression without amplification in breast cancer cases

Background: Immunohistochemistry (IHC) and fluorescent-in situ hybridization (FISH) are standard methods to assess human epidermal growth factor receptor 2 (HER2) status in breast cancer (BC) patients. Real-time quantitative polymerase-chain-reaction (qRT-PCR) is able to detect HER2 overexpression. Here we compared FISH, IHC, quantitative PCR (qPCR), and qRT-PCR to determine the concordance rates and evaluate their relative roles in HER2 determination. Patients and methods: We determined HER2 status in 153 BC patients, using IHC, FISH, Q-PCR and qRT-PCR. In discordant cases, we directly measured HER2 protein levels using Western blotting. Results: The overall agreement (OA) between FISH and Q-PCR was 94.1, with a k value of 0.87. Assuming FISH as the standard reference, Q-PCR showed an 86.1% sensitivity and a 99.0% specificity with a global accuracy of 91.6%. OA between FISH and qRT-PCR was 90.8% with a k value of 0.81. Of interest, the disagreement between FISH and qRT-PCR was mostly restricted to equivocal cases. HER2 protein analysis suggested that qRT-PCR correlates better than FISH with HER2 protein levels, particularly where FISH fails to provide conclusive results. Significance: qRT-PCR may outperform FISH in identifying patients overexpressing HER2 protein. Q-PCR cannot be used for HER2 status assessment, due to its suboptimal level of agreement with FISH. Both FISH and Q-PCR may be less accurate than qRT-PCR as surrogates of HER2 protein determination

Sequential dose-dense 5-fluorouracil, epirubicin and cyclophosphamide followed by docetaxel in patients with early breast cancer with four or more positive lymph nodes.

Aim The aim of present study was to investigate the feasibility of a densified sequence of FEC75 (5-fluorouracil 600 mg/m2, epirubicin 75 mg/m2, cyclophosphamide 600 mg/m2) and docetaxel 100 mg/m2 (D100) in patients with primary operable highrisk breast cancer. Methods Fifty-one consecutive patients with resectable breast cancer and 4 or more positive axillary lymph nodes were enrolled. After a common regimen of 4 cycles of FEC75 given every 14 days, patients received 4 cycles of D100 every 14 days. Prophylactic granulocyte colony-stimulating factor was administered subcutaneously at 5 mg/kg daily from days 5 to 10 to each patient. Results The primary endpoint was the proportion of subjects receiving at least 85% of the relative dose intensity (rDI) both in the FEC and docetaxel parts of the regimen. In view of the high percentage of grade 3–4 skin toxicity (32%) observed in the first 25 patients (Group A) during D100 treatment, it was decided to continue the study using a docetaxel dose reduced by 15% (85 mg/m2; D85). This second group of 26 patients was defined as Group B. Of the total 51 patients, 38 (75%) received docetaxel rDI ≥85%, 23/26 patients (88.5%) and 15/25 patients (60.0%) in Group B and Group A, respectively. The observed grade 3–4 hematological and nonhematological toxicities were in line with data from the literature. The only significant difference was the higher percentage of grade 3–4 skin toxicity experienced with D100. Conclusion This study failed to demonstrate the feasibility of a dose-dense FEC-D regimen with docetaxel 100 mg/m2. Docetaxel 85 mg/m2 seems to allow a higher rDI than docetaxel 100 mg/m2 but this should be confirmed in a larger cohort of patients. </jats:sec

Extra\u2011abdominal fibromatosis: Clinical and therapeutic considerations based on an illustrative case

Extra\u2011abdominal fibromatosis is a rare, benign disease that is characterized by a local but not metastatic invasivity. In particular, desmoid tumors of the chest wall represent only 10\u201120% of all deep fibromatoses. The disease occurs more often in females and has a higher incidence between puberty and the fourth decade of life. The present study reports the case of a 34\u2011year\u2011old female who came to our attention due to a voluminous mass in the right subcostal region. The magnetic resonance imaging of the upper abdomen confirmed the presence of a neoplasm localized between the anterior hepatic margin and the right costal plane. Through a right subcostal laparotomy, the voluminous 95x45x94\u2011mm neoplasm was excised. Histological examination showed evidence consistent with extra\u2011abdominal fibromatosis. The patient has not shown recurrence of the disease for 4 years since the surgery. Overall, radical surgery with disease\u2011free resection margins is the prime treatment option for this disease. Other therapeutic options, such as radiotherapy, hormonal therapy or treatment with imatinib mesylate, can also be considered in certain cases
