How to Perform Repeat Sentinel Node Biopsy Safely After a Previous Mastectomy: Technical Features and Oncologic Outcomes.

BACKGROUND: The latest National Comprehensive Cancer Network Breast Cancer Guidelines still discourage repeat sentinel node biopsy (SNB) after mastectomy, and the largest multicentric study available reports only 35 cases in the absence of previous axillary dissection (AD). METHODS: From January 2003 to November 2018, 89 patients of the European Institute of Oncology with local recurrence of breast cancer after mastectomy, free of distant metastases, with a clinically negative axilla and a negative axillary ultrasound, in absence of AD, underwent lymphatic mapping before wide local excision. RESULTS: During surgery, SNB was successful for 99% of the patients, with 14% being metastatic. Additional metastatic nodes removed by AD after a positive sentinel node occurred in 82% of cases. After a medium follow-up period of 3.7 years, the overall survival rate was 96.7%, and the disease-free survival rate was 84.4%. No axillary relapse after AD was recorded. One patient who refused human epidermal growth factor receptor 2 (HER2)-targeted treatment experienced ipsilateral axillary recurrence after a negative repeat SNB. The first axillary level was never directly irradiated because all the patients with positive repeat SNB underwent AD. For invasive luminal-like HER2-negative recurrences, the metastatic sentinel node was significantly associated with the choice to prescribe adjuvant chemotherapy (p = 0.003). CONCLUSIONS: In specialized centers, repeat axillary SNB for patients with local recurrence after mastectomy in the absence of previous AD can represent a safe option for detection and removal of occult axillary disease that would otherwise not be excised/irradiated to achieve better local control and could possibly influence the choice of adjuvant treatments.

Modified-BEP Chemotherapy in Patients With Germ-Cell Tumors Treated at a Comprehensive Cancer Center.

OBJECTIVES: Bleomycin, etoposide, and cisplatin (BEP) is the most common and successful chemotherapy regimen for germ-cell tumor (GCT) patients, accompanied by a bleomycin-induced dose-dependent lung toxicity in certain patients. In an attempt to reduce bleomycin-toxicity, we developed a modified-BEP (mBEP) regimen. MATERIALS AND METHODS: Between August 2008 and February 2018, 182 unselected mainly testicular GCT patients (39 with adjuvant purpose and 143 with curative purpose) received a tri-weekly 5-day hospitalization schedule with bleomycin 15 U intravenous (IV) push on day 1 and 10 U IV continuous infusion over 12 hours on days 1 to 3, cisplatin 20 mg/m IV, and etoposide 100 mg/m IV on days 1 to 5. Pulmonary toxicity was assessed through chest computed tomography scan and clinical monitoring. RESULTS: Median number of mBEP cycles was 3 (range: 1 to 4). In the curative setting, according to the International Germ Cell Cancer Collaborative Group (IGCCCG) prognostic system, 112, 21, and 9 patients had good-risk, intermediate-risk, and poor-risk class, respectively; 66 (46%) patients had complete response (CR), 67 (47%) had partial response (52 of whom became CR afterwards), 6 (4%) had stable disease (that in 3 became CR afterwards), 3 (2%) progressed, and 1 (1%) died of brain stroke. At a median follow-up of 2.67 years (interquartile range: 1.23-5.00 y), 1 and 5-year overall survival and progression-free survival were 99% and 95%, and 90% and 88%, respectively. In the entire patient population, there was grade 3/4 neutropenia in 92 patients (51%), febrile neutropenia in 11 patients (6%), grade 1/2 nausea in 74 patients (41%), and no death due to pulmonary toxicity. CONCLUSION: In GCT patients, our mBEP-schedule would suggest an effective treatment modality without suffering meaningful pulmonary toxicity.

Phase II Study With Epirubicin, Cisplatin, and Infusional Fluorouracil Followed by Weekly Paclitaxel With Metronomic Cyclophosphamide as a Preoperative Treatment of Triple-Negative Breast Cancer.

BACKGROUND: The aggressive biological behavior and the lack of target therapy prompts the search for new therapeutic approaches for triple-negative breast cancers. PATIENTS AND METHODS: We evaluated the efficacy in terms of Ki-67 variation and clinical response but also the toxicity of a neoadjuvant regimen based on metronomic principles including ECF (epidoxorubicin with cisplatin on day 1 with low-dose 5-fluorouracil in continuous infusion every 21 days for 4 courses) followed by paclitaxel (90 mg/m(2)) on day 1, 8, and 15 every 28 days for 3 courses in combination with metronomic oral cyclophosphamide 50 mg/d for 12 weeks in patients with HER2-negative breast cancer (T2-T4a-d, N0-3, M0) with estrogen receptor and progesterone receptor < 10%. RESULTS: We enrolled 34 patients from June 2009 to May 2013. All were considered evaluable on an intention-to treat basis. The mean difference between the percentage of Ki-67 positive cells evaluated in surgical resection specimens and in pretreatment tumor core biopsy was 41% (95% confidence interval [CI], 30-51; P < .0001) for the entire population, and 22% (95% CI, 7-38; P = .0097) in patients who did not achieve pathological complete response (pCR). Responses to the treatment were obtained in 31 patients [91%] of the patients, and 19 patients (56%; 95% CI, 35-70) had a pCR. Stable disease was observed in 3 patients and none had progressive disease. Grade ≥ 3 hematologic adverse events included leukopenia in 9% (3 of 34), neutropenia in 38% (13 of 34), and anemia in 3% (1 of 34) of patients. Nonhematologic Grade ≥ 3 toxicities included only stomatitis in 1 patient. CONCLUSION: A neoadjuvant program with an ECF regimen followed by weekly paclitaxel with metronomic cyclophosphamide proved to be very effective, with high pCR rates, reduction of Ki-67, and it was associated with a low toxicity profile.

A risk score based on histopathological features predicts higher risk of distant recurrence in premenopausal patients with lymph node-negative endocrine-responsive breast cancer.

PURPOSE: To develop a Risk Score (RS) to predict distant recurrence among premenopausal women with node-negative endocrine-responsive early breast cancer. METHODS: The Cox model was used to develop the RS using clinical and histopathological features from 378 women participating in the IBCSG Trial VIII who received endocrine therapy alone or following chemotherapy. The performance of the resulting model was validated on a cohort of 1005 patients from a single institution who received endocrine therapy alone. RESULTS: In a multivariable analysis, the risk of distant recurrence was associated with tumor size, ER, Ki-67 and peritumoral vascular invasion. In the validation cohort, patients with high RS were at greater risk of distant recurrence compared to patients with low RS (HR, 17.41; 95% CI, 5.72-52.95). CONCLUSION: In premenopausal women with node-negative endocrine-responsive early breast cancer, the RS identifies patients at higher risk of distant recurrence.

Infusional fluorouracil, epirubicin, and cisplatin followed by weekly paclitaxel plus bevacizumab in locally advanced breast cancer with unfavorable prognostic features.

The objective of this study was to evaluate the clinical and biological activities of bevacizumab in combination with preoperative anthracyclines and taxane-based chemotherapy in locally advanced breast cancer selected for unfavorable prognostic features. Patients with cT2-4c, cN0-2, estrogen and progesterone receptors less than 10% of the cells or cT4d and any estrogen/progesterone receptors expression received four courses of ECF-chemotherapy (epirubicin, cisplatin, fluorouracil as continuous infusion) followed by three courses of weekly paclitaxel in combination with bevacizumab. Thirty patients were included in the study. An objective response, either complete or partial, was observed in 26 patients (87%; 95% confidence interval: 69-96%), stable disease was observed in two patients (7%), and two patients (7%) progressed. A pathological complete response was obtained in 10 patients (33%; 95% confidence interval: 17-53%). Side effects related to bevacizumab with grade >or=2 included headache and hypertension. A nonstatistical significant decrease in the median value of circulating endothelial cells was observed at surgery (3.0/microl vs. 5.7/microl, P=0.19). In conclusion, high rates of both clinical and pathological responses with anthracycline-containing chemotherapy followed by weekly paclitaxel plus bevacizumab were observed in locally advanced breast cancer with unfavorable prognostic features. A non-negligible rate of progressive disease was observed, suggesting careful monitoring of the patients. Further studies evaluating the potential benefit of bevacizumab in neoadjuvant treatment need to be tested.

Coffee drinking and hepatocellular carcinoma risk: a meta-analysis.

UNLABELLED: Several studies suggest an inverse relation between coffee drinking and risk of hepatocellular carcinoma (HCC). We conducted a meta-analysis of published studies on HCC that included quantitative information on coffee consumption. Ten studies were retrieved (2,260 HCC cases), including 6 case-control studies from southern Europe and Japan (1551 cases) and 4 cohort studies from Japan (709 cases). The summary relative risk (RR) for coffee drinkers versus non-drinkers was 0.54 (95% confidence interval [CI] 0.38-0.76) for case-control studies and 0.64 (95% CI 0.56-0.74) for cohort studies. The overall RR was 0.59 (95% CI 0.49-0.72), with significant heterogeneity between studies. The overall summary RR for low or moderate coffee drinkers was 0.70 (95% CI 0.57-0.85), and that for high drinkers was 0.45 (95% CI 0.38-0.53). The summary RR for an increase of 1 cup of coffee per day was 0.77 (95% CI 0.72-0.83) from case-control studies, 0.75 (95% CI 0.65-0.85) from cohort studies, and 0.77 (95% CI 0.72-0.82) overall. The consistency of an inverse relation between coffee drinking and HCC across study design and geographic areas weighs against a major role of bias or confounding. Coffee drinking has also been related to reduced risk of other liver diseases, thus suggesting a continuum of the favorable effect of coffee on liver function. However, subjects with liver conditions may selectively reduce their coffee consumption. CONCLUSION: The present analysis provides evidence that the inverse relation between coffee and HCC is real, though inference on causality remains open to discussion.
