RESUMO
OBJECTIVES: We conducted a phase 2 trial to assess the feasibility of interval cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy (HIPEC) with cisplatin in patients with stage III and IV pleural ovarian carcinoma in first-line treatment with no macroscopic residual disease after surgery. METHODS: Patients could be treated either with primary CS with HIPEC followed by 6 conventional cycles of chemotherapy or with 3 or 4 cycles of neoadjuvant chemotherapy before CS with HIPEC and 3 postoperative chemotherapy cycles. Hyperthermic intraperitoneal chemotherapy was performed with cisplatin (50 mg/m) for 60 minutes, only in case of complete cytoreduction. RESULTS: Nineteen patients were included in the study, and they all underwent neoadjuvant chemotherapy before CS. Sixteen patients underwent complete CS with HIPEC. There was no mortality, and morbidity of CS with HIPEC was acceptable. The HIPEC procedure did not prevent the administration of the standard first-line treatment. In the 16 patients who underwent CS with HIPEC, the outcomes were very good. CONCLUSION: Our study shows an acceptable toxicity of adding HIPEC to the standard first-line treatment in patients with stage III ovarian carcinoma treated with interval CS. Further studies are needed to confirm the role of HIPEC in the treatment of ovarian carcinoma.

INTRODUCTION: A simultaneous integrated boost (SIB) intensity modulated radiotherapy (IMRT) in patients with head and neck squamous cell carcinoma (HNSCC) allows to irradiate different target volumes to different dose levels within a single treatment session without increasing the toxicity. AIM: To analyze the outcome and toxicity of patients treated by definitive or postoperative SIB IMRT for HNSCC. MATERIAL AND METHODS: 106 patients with HNSCC of the oral cavity (OC), oropharynx (OP), larynx (L) and hypopharynx (HP), consecutively treated at our cancer center between 3/2012 and 3/2014 were retrospectively analyzed. The prescribed SIB IMRT doses were in the postoperative setting (group A) 60-66â¯Gy and 53â¯Gy in 30-33 fractions for PTV high risk and PTV elective, respectively; and 70â¯Gy and 56â¯Gy in 35 fractions for PTV high risk and PTV elective, respectively when given as primary treatment (group B). Toxicity was consistently graded according to RTOG/EORTC scale. RESULTS: Median follow-up duration was 31â¯months. Thirty (28%) patients were postoperatively irradiated (group A) and 76 (72%) patients received definitive IMRT (group B). At 3â¯years, loco-regional control, distant control and overall survival were 78%, 78%, 57% and 64%, 76%, 52% in the postoperative (group A) and the definitive SIB IMRT group (group B), respectively. The observed acute grade 3 toxicities were dysphagia (44%), oral and/or oropharyngeal mucositis (40%) and dermatitis (21%). Late toxicity was predominantly clinically significant xerostomia (42%), dysgeusia (23%) and dysphagia (8%). CONCLUSION: SIB IMRT is feasible, safe and effective in the treatment of HNSCC patients.
