    Esophageal cancer ranks sixth among the causes of death from cancer worldwide. Patients undergoing surgery have a median survival ranging from 13 to 19 months; 2-year survival rates range from 35 to 42 percent, and 5-year survival rates from 15 to 24 percent. In particular, the 3 year survival (= SVV) is about 26%, with a median survival of 17 months. An interesting point is that about 20-25% of the patients has only locoregional involvement as pattern of failure. At least two randomized studies reported about the combined use of radiotherapy and chemotherapy as sensibilization. They assessed that patients treated with chemoradiation had a longer median survival compared to patients receiving radiation therapy alone, both in early and advanced stages. Moreover radiochemotherapy seems able of achieving high rates of downstaging and of increasing overall and disease-free survival

    Molecularly targeted therapy and radiotherapy in the management of localized gastrointestinal stromal tumor (GIST) of the rectum: a case report

    Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. The main treatment for localized gastrointestinal stromal tumors is surgical resection. These tumors respond poorly to conventional cytotoxic chemotherapy agents and to radiotherapy. Imatinib mesylate, a small-molecule kinase inhibitor, has proved useful in the treatment of recurrent or metastatic GISTs and is now being tested in the adjuvant and neoadjuvant setting. The role of radiotherapy in the management of patients with GIST is currently restricted to symptomatic palliation. We present the case of a 54-year-old man affected by rectal GIST extending to the anal canal, with constipation, hematochezia, and anal pain. He received imatinib, 400 mg orally per day, for a week before and during radiation therapy. Irradiation was delivered to the gross tumor volume by 3D conformal therapy. The planned total dose was 50.4 Gy in fractions of 1.8 Gy daily. We observed a partial clinical response 3 weeks after the end of combination treatment. The patient then underwent a sphincter-saving surgical procedure. There was no perioperative morbidity and a complete pathological response was obtained. At the present time, the role of radiotherapy in the management of patients with GIST is restricted to symptomatic palliation. The introduction of molecularly targeted therapy combined with radiation therapy could improve the outcomes for patients diagnosed with GIST
