88 Background: There is not yet a consensus on the efficacy and safety of IMRT for the treatment of patients with esophageal carcinomas. We report on our experience with outcomes and toxicity with IMRT for these patients. Methods: Fifty-five patients with esophageal carcinoma were treated with IMRT at our institution from 12/2008 and 12/2014. Medical records were retrospectively reviewed. All patients received concurrent chemotherapy (majority 5-FU with oxaliplatin). Thirty-one (56%) patients underwent surgery. Fifty (91%) received 50.4 Gy in 28 fractions. Seventy-three percent of cases were adenocarcinoma. Regions include mid-thoracic (15%), lower thoracic (64%), and GE junction (22%). Clinical uT-stages were as follows: T1 (2%), T2 (20%), T3 (69%), and T4a (5%). Clinical N-stages were as follows: N0 (33%), N1 (53%), N2 (13%), and N3 (2%). Results: Median follow-up for all patients was 15 months (1.5 - 64.5) and 25.5 months (1.5 - 64.5) for patients who were alive at follow-up (n = 31). Fifty-one (93%) patients completed RT. Of the 31 patients who underwent surgery, 9 (29%) were found to have a complete pathologic response. Site of first recurrence was local (n = 2, 4%), regional (n = 3, 6%), and distant (n = 14, 26%). At 12 and 24 months, overall survival was 72% and 58%, freedom from recurrence was 78% and 65%, and freedom from distant recurrence was 78% and 68%. On univariate analysis, improved OS was noted with patients who underwent surgery (RR 0.29) or were cN0 (RR 0.27). Twenty eight patients (51%) experienced > / = CTCAE v.4grade 3 acute toxicity; notable were hematologic (n = 14, 25%), esophagitis (n = 6, 11%), acute coronary event (n = 1, 2%), and post-chemoRT pneumonia (n = 1, 2%). Fifteen patients (31%) experienced > grade 3 late toxicity; notable were esophageal stricture (n = 7, 14%), post-op pneumonia (n = 3, 6%), post-CRT pneumonia (n = 2, 4%), and COPD exacerbation (n = 1, 2%). Conclusions: Patient receiving IMRT with concurrent chemotherapy for esophageal carcinomas have good LC rates, with or without surgery. Majority of patients are able to finish treatment with acceptable rates of late toxicity. Patient who underwent surgery or were cN0 had better OS.

Human T-cell lymphoma virus (HTLV)-associated adult T-cell leukemia lymphoma is a rare cancer in the United States, but there are several areas around the world where the virus is endemic. HTLV-associated adult T-cell leukemia lymphoma has been associated with leukemic arthropathy. We present a patient with HTLV-associated adult T-cell leukemia lymphoma with leukemic arthropathy. Although non-steroidal anti-inflammatory drugs and chemotherapy are often used for treatment, we describe the successful use of radiation therapy in the palliative relief of symptoms from leukemic arthropathy.
