This is the first mobility 87Sr/86Sr analysis in human remains made on the Balearic Islands. Eight human individuals buried at the same Late Iron Age funerary chamber of Son Ferrer site (Calvià, Mallorca) have been sampled for strontium and oxygen isotopic analysis (87Sr/86Sr and δ 18O). The study includes strontium and oxygen isotopic analysis of domestic mammals buried in the same Funerary Area (FA1) together with present-day vegetation and archaeological bone to assess the strontium isotopic ratios (87Sr/86Sr) around the site. All the results are compatible with the 87Sr/86Sr documented in Mallorca and, more specifically, with the surrounding bedrocks from the site. Humans, caprines, and dogs provided similar results and no significant differences are found between the species. The only exception is a caprine which shows seasonal movement through the period of enamel mineralisation. The isotopic information agrees with the previous studies, which proposed that Son Ferrer site was a symbolic place for the surrounding territory where people from the nearby villages were buried.

Background: In selected patients with rectal cancer, laparoscopic surgery is as safe as open surgery, with similar resection margins and completeness of resection. In addition, recovery is faster after laparoscopic surgery. We analyzed long-term outcomes in a group of patients with locally advanced rectal cancer (LARC) treated with preoperative therapy followed by laparoscopic surgery and intraoperative electron-beam radiotherapy (IOERT)., Methods and Materials: From June 2005 to December 2010, 125 LARC patients were treated with 2 induction courses of FOLFOX-4 (oxaliplatin 85 mg/m(2)/d1, intravenous leucovorin at 200 mg/m(2)/d1-2, and an intravenous bolus of 5-fluorouracil 400 mg/m(2)/d1-2) and preoperative chemoradiation (4,500-5,040 cGy) followed by total mesorectal excision (laparoscopic, 35 %; open surgery, 65 %) and a presacral boost with IOERT., Results: Patients in the laparoscopic surgery group lost less blood (median 200 vs 350 mL, p < 0.01) and had a shorter hospital stay (7 vs 11 days; p = 0.02) than those in the open surgery group. Laparoscopic procedures were shorter than open surgery procedures (270 vs 302 min; p = 0.67). Postoperative morbidity (32 vs 44 %; p = 0.65), RTOG grade ≥3 acute toxicity (25 vs 25 %; p = 0.97), and RTOG grade ≥3 chronic toxicity (7 vs 9 %; p = 0.48) were similar in the laparoscopy and open surgery groups. The median follow-up time for the entire cohort of patients was 59.5 months (range 7.8-90); no significant differences were observed between the groups in locoregional control (HR 0.91, p = 0.89), disease-free survival (HR 0.80, p = 0.65), and overall survival (HR 0.67, p = 0.52)., Conclusions: Postchemoradiation laparoscopically assisted IOERT is feasible, with an acceptable risk of postoperative complications, shorter hospital stay, and similar long-term outcomes when compared to the open surgery approach.
