192 Background: Patient privacy is of the utmost importance for the emotional needs of a cancer patient and their family. As an effort to improve privacy, quality, and coordination of care within our Radiation Oncology department, in 2016 a patient pager system was devised to inform patients to prepare for daily treatment rather than verbally call the patient's name in waiting rooms. Methods: During June 2016, patients undergoing daily radiation therapy participated in a six-question survey addressing various aspects of the paging service, privacy prior to pager use, and demographics. Six radiation therapists also participated in a 7-question survey addressing privacy and workflow. Participants rated their experience on a scale of 1 to 5 (1 being poor, 5 being excellent). Surveys were collected and retrospectively reviewed. Results: 42 patients completed the survey. Patients rated "Very Good" to "Excellent" for the following categories: “Paging system more convenient than being called”(4.6), “Protection of privacy”(4.6), “Easiness”(4.7) and whether “Pager should be utilized for all appointments” (4.3). Patients rated “Patient privacy when name is called” as "Good" to "Very Good" (3.7). Seven patients also underwent therapy prior to pager implementation and rated the new system in comparison as "Very Good" to "Excellent" for “Privacy protection”(4.6), “Efficiency” (4.6), and “Satisfaction” (4.6). Only 24 filled out demographic information. Of the 24 patients, 54% of patients were female, 87% were above the age of 50, and all patients were receiving at least 10 treatments. Staff rated "Fair" to "Very Good" for “More preparation time” (2.8), “Patient use difficulty”(3.2), “Patient positive feedback”(2.3), “Receiving patients” (2.2) and “Workflow” (2). However, “Patient privacy” was rated as "Very Good" to "Excellent" (4.2). Conclusions: Overall, patients and staff highly rated the paging system for protecting privacy in the waiting room. Patients who experienced waiting room procedure prior to pager implementation display greater satisfaction with a paging system. However, it did not change overall workflow. Our study shows clinics should prioritize patient privacy in the waiting room to improve the emotional needs of the patient.

764 Background: Psychosocial distress screening and assessment in patients with gastrointestinal (GI) cancers has an established importance due to the distress experienced during and post treatment. GI cancer patients receiving radiotherapy (RT) for curative or palliative measures were reviewed in order to determine if there was a relationship between patient reported distress (PRD) and survival. Methods: Patients at our institution who receive external beam RT for GI cancers completed a 30 question PRD survey that also included a linear analog measure of overall distress, the National Comprehensive Cancer Network (NCCN) Distress Thermometer, which ranged from 1 (low overall distress) to 10 (high overall stress) at the start of and/or during treatment. Each question on the PRD questionnaire concentrated on a possible cause of distress. It allowed patients to rate distress levels for each question from 1 to 5 (1 being the least distressed and 5 being the most distressed), and also overall distress according. The reported clinical results of the PRD questionnaire were retrospectively reviewed in patients receiving RT for GI cancers from Jan 2012 to Aug 2015. Patients were considered distressed if their overall PRD score was 5 or greater (PRD+) or not distressed (PRD-) if their score was 4 or under. Overall survival between PRD+ and PRD- was compared using the Kaplan-Meier method. Results: PRD surveys were completed by 134 consecutive patients, 67 (50%) male and 67 (50%) female within 30 days of starting RT. The median age was 65 years (range 28 to 93). The top histological finding was adenocarcinoma, 90 patients (60%). 113 (84%) received chemotherapy and 64 (48%) underwent surgery. 102 (75%) treatments were curative and 32 (25%) were palliative. Overall NCCN distress thermometer results ranged from 0 to 10, with a median of 4. Median follow-up was 2.7 years. Distressed patients (PRD+) had inferior survival to those not distressed (PRD-) at 2 years, 52% vs. 72%, p<0.02. Conclusions: Patient reported distress is associated with an inferior survival in patients receiving radiotherapy for gastrointestinal tumors.

211 Background: The current standard of care for locally advanced esophageal cancer includes chemoradiotherapy with or without surgery. Radiation is usually delivered via a 3D technique. IMRT has been utilized in the treatment of multiple tumors and demonstrated similar efficacy while offering the possibility of decreased toxicity. Methods: Thirty-six patients were treated with IMRT and chemotherapy. Twenty-one patients underwent surgical resection. Eleven underwent open surgery and the remainder underwent minimally invasive surgery. Chemotherapy consisted primarily of 5-FU with oxaliplatin or cisplatin. All but two patients received 50.4 Gy; one patient received 41.4 Gy without surgery and one patient discontinued treatment after 25.2 Gy. Eleven patients required a treatment break during radiotherapy. The median age was 69 (range 46-87). Approximately two-thirds of tumors were adenocarcinomas located in the lower thorax. Two thirds of patients were staged as T3 and had positive lymph nodes. The median tumor size was 5 cm (range 2-13). Results: With a median follow-up of 21.3 months (range 2.4-44.8) and 33.9 months for survivors (range 3.7-44.8), overall survival at 24 months was 55%. The 24 month overall survival was 75% vs 24% for surgical and non-surgical patients, respectively. Seven patients had a complete pathologic response. Twenty-four patients experienced grade 3 or higher acute toxicity and there was one grade 5 toxicity. Acute toxicity was similar between surgery and non-surgery patients. Fourteen patients experienced grade 3 or higher late toxicity; 9 surgery and 5 non-surgery patients. The most frequent late toxicity was grade 3 stricture (21%). On multivariate analysis, advanced age (RR [10 year increase] 2.01, p=0.032) and heart maximum dose >55 Gy (RR 3.73, p=0.011) were associated with decreased survival. Conclusions: Patients who undergo surgery after chemoradiotherapy demonstrate improved survival; however, this may be related to underlying comorbidities that preclude surgery. IMRT appears to be a reasonable treatment option that may reduce complications from radiotherapy. Careful attention should be given to heart dose during treatment planning.

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.

211 Background: Distress is known to be elevated in patients receiving cancer therapy, such as palliative radiotherapy (PRT). Many patients will experience distress during treatment and it is not always addressed in part due to a lack of guidance regarding the significance of distress. Methods: All RT patients in our clinic are asked to complete a patient reported distress (PRD) survey during treatment course. PRD forms consist of 30 categorical questions that assess distress subscales. Patients have the option to rate each question from 1 (low distress) to 5 (high distress). The survey also includes the National Comprehensive Cancer Network distress thermometer, which allows patients to rate overall distress level from 0 (no distress) to 10 (extreme distress). Patients’ records were retrospectively reviewed to abstract the needed information to assess survivorship. Results: 270 patients were included from 01/18/2012-08/07/2015. Overall PRD was analyzed as a continuous and a categorical variable (low: 0-3, moderate: 4-6, high: 7-10). Continuous and categorical variable PRD did not show a correlation of distress to survival (P = 0.26) and (P = 0.10) respectively. A correlation was noted in moderate distress category (RR: 1.51, P = 0.034), however, this was not noted in high distress category (RR: 1.25, P = 0.33). There was no statistical significant correlation with the adjusted variables. Patients with primary site of gastrointestinal cancer had worst prognosis (RR: 1.34, P: 0.14), while hematological origin had best prognosis (RR: 0.35, P: 0.038).Age had the strongest correlation with survival, as older patients receiving RT had poorer survival (RR: 1.13, P: 0.079). Conclusions: This study suggests that PRD is not predictive of survival in PRT. The primary goal of PRT is to improve quality of life (QoL) by assessing, anticipating and alleviating suffering; not necessarily improve survival. It also demonstrated that the most common stressors were related to reversible short-term side effects of RT such as fatigue and pain rather than long-term stressors related to daily activities and social measures which might affect QoL. It is imperative to explore assessment tools to mitigate suffering and improve strategies to enhance QoL in all medical disciplines.

Prostate cancer is the most common malignancy of men in the United States. Small-cell carcinoma (SCC), which typically presents as an aggressive lung malignancy, is a rare diagnosis within the setting of prostate cancer pathology. Due to its limited prevalence, little information regarding the treatment and prognosis of this disease in large populations is available. To date our current knowledge base is largely limited to case reports and retrospective case reviews. The mainstay of treatment for this particular histology most often involves a multimodality approach utilizing chemotherapy in conjunction with radiation therapy, androgen deprivation therapy, or prostatectomy. Here we present the case of an elderly 89-year-old Caucasian male who was diagnosed with SCC of the prostate. Despite proceeding with a course of definitive radiotherapy, the patient experienced rapid progression of disease and ultimately elected to discontinue radiation therapy and receive hospice care.

Purpose To describe outcomes of salvage radiotherapy (SRT) for men with detectable prostate-specific antigen (PSA) after radical prostatectomy for prostate cancer and identify associations with outcomes. Patients and Methods A total of 1,106 patients received SRT between January 1987 and July 2013, with median follow-up 8.9 years. Outcomes were estimated using Kaplan-Meier for overall survival (OS) and cumulative incidence for biochemical recurrence (BcR), distant metastases (DM), and cause-specific mortality (CSM). Variable associations with outcomes used Cox or Fine-Gray methods, as appropriate. Multiple variable analyses used backward selection with P < .05 for retention. Results In multiple variable analyses, pathologic tumor stage, Gleason score, and pre-SRT PSA were associated with BcR, DM, CSM, and OS; androgen suppression and SRT doses > 68 Gy were associated with BcR; and age was associated with OS. Each pre-SRT PSA doubling increased significantly the relative risk of BcR (hazard ratio [HR], 1.30; P < .001), DM (HR, 1.32; P < .001), CSM (HR, 1.40; P < .001), and all-cause mortality (HR, 1.12; P = .02). Using a pre-SRT PSA cutoff ≤ 0.5 versus > 0.5 ng/mL, 5-year and 10-year cumulative incidences for BcR were 42% versus 56% and 60% versus 68% ( P < .001), DM 7% versus 14% and 13% versus 25% ( P < .001), CSM 1% versus 4% and 6% versus 13% ( P < .001), and OS of 94% versus 92% and 83% versus 73% ( P > .05). Conclusion SRT outcomes are in part affected by factors associated with prostatectomy findings but may be positively affected by using SRT at lower PSA levels, including reductions in BcR, DM, CSM, and all-cause mortality. These findings argue against prolonged monitoring of detectable postprostatectomy PSA levels that delay initiation of SRT.

Hidradenocarcinoma is a rare aggressive form of cutaneous adnexal skin carcinoma originating from the sweat gland. Due to its low incidence, prognostic and treatment strategies are still being explored both for primary and advanced disease. This tumor most often presents as either solid or cystic appearing subcutaneous nodules, which may be associated with pruritus or ulceration. To date the mainstay of treatment for local disease has been surgical excision; however, the paucity of historical data available has shown that these tumors often behave aggressively with high rates of local recurrence, metastasis, and poor overall outcomes. There are few case reports describing the utility of radiation therapy in the treatment of hidradenocarcinoma. Herein, we present a case of metastatic apocrine hidradenocarcinoma in a 32-year-old Caucasian male. The patient initially underwent excisional biopsy which confirmed the diagnosis of poorly differentiated, highly infiltrative, apocrine hidradenocarcinoma. He received systemic chemotherapy for metastatic disease, followed by radiation therapy to areas of grossly palpable adenopathy. Prior to radiation therapy the patient had an enlarged hypermetabolic conglomerate of lymph nodes in the right axilla, and borderline enlarged low activity nodes within the left axilla. He received 3 cycles of chemotherapy followed by tamoxifen and radiation therapy (50.4 Gy in 28 fractions) to areas of progressive disease in the bilateral axilla, lower neck, and axillary skin. Following treatment, the patient had complete resolution of skin nodules and improvement of his pruritus. While the role of radiation therapy in the treatment of hidradenocarcinoma has not been well established, this case report demonstrated the potential benefit of external beam radiotherapy in the management of this rare disease.

Objective To update a previously proposed prognostic scoring system that predicts risk of biochemical recurrence ( BCR ) after salvage radiation therapy ( SRT ) for recurrent prostate cancer when using additional patients and a PSA value of 0.2 ng/ mL and rising as the definition of BCR . Patients and Methods We included 577 patients who received SRT for a rising PSA after radical prostatectomy in this retrospective cohort study. Clinical, pathological, and SRT characteristics were evaluated for association with BCR using relative risks ( RR s) from multivariable Cox regression models. Results With a median follow‐up of 5.5 years after SRT , 354 patients (61%) experienced BCR . At 5 years after SRT , 40% of patients were free of BCR . Independent associations with BCR were identified for the PSA level before SRT ( RR [doubling]: 1.25, P < 0.001), pathological tumour stage ( RR [T3a vs T2] 1.21, P = 0.19; RR [T3b/T4 vs T2] 2.09, P < 0.001; overall P < 0.001), Gleason score ( RR [7 vs <7] 1.63, P < 0.001; RR [8–10 vs <7] 2.28, P < 0.001; overall P < 0.001), and surgical margin status ( RR [positive vs negative] 0.71, P = 0.003). We combined these four variables to create a prognostic scoring system that predicted BCR risk with a c ‐index of 0.66. Scores ranged from 0 to 7, and 5‐year freedom from BCR for different levels of the score was as follows: Score = 0–1: 66%, Score = 2: 46%, Score = 3: 28%, Score = 4: 19%, and Score = 5–7: 15%. Conclusion We developed a scoring system that provides an estimation of the risk of BCR after SRT . These findings will be useful for patients and physicians in decision making for radiation therapy in the salvage setting.
