Aim: To study the impact of tumour regression occurring during IMRT for locally advanced carcinoma cervix and study dose distribution to target volume and OARs and hence the need for any replanning. Materials and Methods: 40 patients undergoing IM-IGRT and weekly chemotherapy were included in the study. After 36 Gy, a second planning CT-scan was done and target volume and OARs were recontoured. First plan (non-adaptive) was compared with second plan (adaptive plan) to evaluate whether it would still offer sufficient target coverage to the CTV and spare the OARs after having delivered 36 Gy. Finally new plan was created based on CT-images to investigate whether creating a new treatment plan would optimize target coverage and critical organ sparing. To measure the response of the primary tumour and pathologic nodes to EBRT, the differences in the volumes of the primary GTV and nodal GTV between the pretreatment and intratreatment CT images was calculated. Second intratreatment IMRT plans was generated, using the delineations of the intratreatment CT images. The first IMRT plan (based on the first CT-scan or non adaptive plan) was compared with second IMRT plan (based on the second CT-scan or adaptive plan). Results: 35% patients had regression in GTV in the range of 4.1% to 5%, 20% in the range of 1.1%-2%, 15% in the range of 2.1%-3% and 20% in the range of 6%-15%. There was significant mean decrease in GTV of 4.63 cc (p=0.000). There was a significant decrease in CTV on repeat CT done after 36 Gy by 23.31 cc (p=0.000) and in PTV by 23.31 cc (p=0.000). There was a statistically significant increase in CTV D98, CTV D95, CTV D50 and CTV D2 in repeat planning CT done after 36 Gy. There was no significant alteration in OARs doses. Conclusion: Despite tumour regression and increased target coverage in locally advanced carcinoma cervix after a delivery of 36 Gy there was no sparing of OARs. Primary advantage of adaptive RT seems to be in greater target coverage with non-significant normal tissue sparing.

Introduction: Locally advanced carcinoma cervix includes stages IIB, IIIA, IIIB and IVA. Interstitial brachytherapy has the potential to deliver adequate dose to lateral parametrium and to vagina. Hence, it is preferable in cases with distorted anatomy, extensive (lower) vaginal wall involvement, bulky residual disease post EBRT and parametrium involvement upto lateral pelvic wall. Aim and Objective: To determine clinical outcome and complications (acute and chronic) in locally advanced carcinoma cervix, treated with interstitial brachytherapy using template (MUPIT - Martinez universal perineal interstitial template). Materials and Methods: This study is a retrospective analysis of 37 cases of locally advanced carcinoma cervix (stage IIB-2, IIIB-30, IVA-5), treated with EBRT (dose-median 45Gy/25#) ± concurrent chemotherapy (CCT) - Inj. Cisplatin/Inj Carboplatin, followed by interstitial brachytherapy using MUPIT from December 2009 to June 2015. Initial treatment with EBRT ± CCT was followed by intertstitial brachytherapy. Under spinal anaesthesia and epidural analgesia, MUPIT application was done. Straight and divergent needles (median 26, range 19-29) were inserted to cover parametrium adequately. Needle position was verified with planning CT scan and Brachytherapy planning was done. Dose was normalized to 5 mm box surface from outermost needle with optimization of dose to OAR (Bladder, Rectum and Sigmoid colon). Prescription dose –25Gy in 5#. Treatment was delivered by Microselectron HDR using Ir192 source. Treatment fractions were delivered twice daily with min 6 Hrs. gap in-between fractions. Results: The median duration of follow-up was 25 months. Local control was achieved in 28 patients with residual disease in 7 patients and local recurrence in 2 patients. 10 patients had acute lower GI toxicity {Grade1 (n=6), Grade 2 (n=4)}, 2 patients had acute Grade 1 bladder toxicity. 1 patient had grade 3 and 1 patient had grade 4 chronic bladder toxicity. Chronic rectal toxicity was seen in 10 patients {Grade 2 (n=4), Grade 3 (n=4), Grade 4 (n=2)}. Conclusion: Local control was achieved in 28/37 patients (75.6%) and overall survival rate of 81.1% at median follow up of 25 months in patients with locally advanced carcinoma cervix and unfavorable prognostic factors.

Long Term Follow Up

PURPOSE Long-term follow-up data of a randomized trial that compared hydroxyurea and the hypoxic-cell radiosensitizer to misonidazole as adjuncts to standard radiation therapy in locally advanced carcinoma of the cervix are reported. PATIENTS AND METHODS Three hundred eight women were entered, and all 294 eligible patients are assessable as randomized. Eighty-one percent of patients have been monitored for 5 years or to death. RESULTS There was an advantage for hydroxyurea in progression-free interval and survival (P = .05 and P = .066, respectively). There was no significant difference in the distribution of sites of failure between the regimens. For the 39% of patients with stages III to IVA disease, the advantage in progression-free interval for hydroxyurea was significant (47.8% v 33.6%). More leukopenia occurred on the hydroxyurea regimen than on the misonidazole regimen. CONCLUSION In summary, these data provide stronger evidence than our previous analysis that hydroxyurea is superior to misonidazole as an adjunct to radiation therapy. For patients with locally advanced carcinoma of the cervix, hydroxyurea continues to be the adjunct of choice with radiation.

4531 Background: The FFCD 9102 trial demonstrated that CRT is an alternative to CRT+S for responding patients. We investigated the type of PP in the follow-up (FU) period, according to the RT scheme: protracted (P-RT) vs. split course (SC-RT). Methods: Resectable T3 N0–1 M0 thoracic esophageal carcinoma were included. First sequence : 2 cycles of cisplatin and 5-FU (day (d)1 - d22) combined with RT. Two schemes of RT were allowed: P-RT (46 Gy / 4.5 weeks (w), 2 Gy / f) or SC-RT (2 one-week courses of 15 Gy, 3 Gy / f). For CRT, the same chemotherapy was given on d43, d64 and d92 combined with 20 Gy / 2w (P-RT) or 15 Gy / 1w (SC-RT). Responding patients after the first sequence were randomized between CRT and CRT+S. The impact of SC-RT vs. P-RT on PP in the FU period was explored using a Mann-Whitney test. Results: From February 1993 to December 2000, 451 pts were registered and 446 were eligible. P-RT: 161 pts, SC-RT: 285 pts. After a median FU of 47.4 months, 2-year overall survival and local relapse-free survival were for P-RT vs. SC-RT: 37.1% vs. 30.5% (p = 0.25) and 76.7% vs. 56.8% (p = 0.002), respectively. P-RT vs. SC-RT: mean length of hospital stay: 48 d vs. 60.5 d (p= 0.0003). Mean number of dilatation sessions: 0.56 vs. 0.66 (p= 0.43). Mean number of stents: 0.21 vs. 0.34 (p= 0.03). Mean number of any PP: 1.01 vs. 1.50 (p= 0.001). Mean dysphagia grade: 2.99 vs. 3.12 (p= 0.21). In the CRT+S-group, P-RT vs. SC-RT: mean length of hospital stay 55.0d vs. 68.7d (p =0.051). Mean number of dilatation sessions: 0.74 vs. 0.74 (p= 0.77). Mean number of stents: 0.09 vs. 0.18 (p= 0.44). Mean number of PP: 1.00 vs. 1.37 (p= 0.054). In the CRT-group, P-RT vs. SC-RT, mean length of hospital stay: 42.6d vs 54.0d (p= 0.053). Mean number of dilatation sessions : 0.38 vs. 0.67 (p= 0.12). Mean number of stents: 0.31 vs. 0.50 (p= 0.03). Mean number of PP: 0.83 vs. 1.86 (p= 0.0005). Conclusions: Stents, rate of PP and length of hospital stay were significantly increased with SC-RT. Dysphagia score was similar between SC-RT and P-RT at last FU. No significant financial relationships to disclose.

e14714 Background: 30-40 % of PC pts present with LAPC. Optimal management remains controversial. Current NCCN guidelines, suggests clinical trial, FOLFIRINOX, G, G based combination therapy, chemo followed by CRT as options in pts with good PS. This single institution retrospective review, evaluated the UC experience of the impact of G+nab-p+/- CRT in LAPC. Methods: From 05/01/09-09/01/11,105 newly registered pts were identifiedusing ICD code 157, 13pts met inclusion criteria: ECOG PS 0-2, histologically proven LAPC, without prior therapy that received G + nab-P, pre or post radiation as part of their treatment. G+nab-p was given as cycles of G=1,000mg/m2 and nab-P=100mg/m2 weekly x3 every 4 weeks with appropriate modifications. CT scans and CA19-9 levels were followed. PFS was estimated from the date of diagnosis to date of progression or death if this occurred first and OS was estimated from date of diagnosis until date of death or loss to follow up. Kaplan Meier survival estimates were obtained with 95% confidence interval (CI). Log rank test was used to compare the PFS according to categorical variables. Results: Median duration of follow up was estimated to be 14.4 months (M) range(R) (5.8-19). CA19-9 data was available for 12 pts, 2 had baseline <1 (R<1-12,861), CA19-9 decrease > 50% from baseline was seen in 9/10. Mean # of G+nab-P cycles administered was 3, R (1-10). 77% received G based CRT with only 1pt receiving this post op. 38% (5/13) underwent resection, 4 post CRT with R0 margins and -ve LN’s and 1 pre CRT with R0 margins but 1/13 LN’s +ve. 11 pts were evaluable for response by RECIST (4PR, 6SD, 1PD). Disease control rate 91%. PFS 92% (CI: 57- 99%) at 6 M and 65% (CI: 31-85%) at 12 M. OS was 85% (CI: 51-96%) at 6M and 77 %(CI: 44-92%) at 12M. At 6M, 100% PFS was observed in resected group, whereas 88% PFS in non-resected group (p=0.12). There was no significant difference in PFS according to gender (p=0.44) and T lesion (p=0.49). Grade III/IV toxicity was mainly hematologic and gastrointestinal. (4/7) 57% received further therapy upon progression. Conclusions: Compared to contemporary G- based trials, the UC experience of G+ nab-P with CRT appears to be associated with improved survival in LAPC and warrants further study.

e21575 Background: Increasing HNC survival highlights the importance of understanding late biopsychosocial outcomes. Financial and occupational impacts of HNC remain unexplored, thus we undertook a qualitative analysis to identify themes and explore the impact of HNC/treatment on survivors’ financial health. Methods: Eligibility: Locally-advanced HNC who participated in an R0-1, NED, and > 1 year post treatment. Ten of 12 eligible patients were interviewed. Topics queried: financial issues related to HNC/treatment, financial/insurance matters affecting treatment, impact of treatment on fiscal responsibilities, financial counseling, and late impact of HNC/treatment on work. Frequency distributions were used to summarize patient characteristics. Interviews were transcribed verbatim, double-coded, and organized into themes and subthemes. Results: 50% male, 100% Caucasian, 60% married, median age 64 years, and median time since treatment of 64 months. Most denied ongoing financial strain from HNC/treatment, citing mitigating factors of preparedness (e.g. preexisting savings), health/disability insurance, and marital status. Those with financial distress noted an income limited by savings or disability. None reported financially-related delays in care. However, 2 patients used free healthcare. Most denied impact of HNC/treatment on financial obligations, but a minority reported subsequent delays in dental care, paying credit card bills, and travel. Financial counseling was used by 4 patients; benefits included decreased stress, access to financial programs, and education. Healthcare providers were considered an important source of financial counseling. Not all patients returned to work; late effects (fatigue, cognitive changes) impaired work capacity for those who did. Limitations: Population may have been skewed by loss to follow-up of patients with financial toxicity that precluded ongoing medical follow-up. Conclusions: Long-term financial distress was limited in this cohort of HNC survivors. Preparedness, adequate insurance, marital status, and financial counseling attenuated financial impacts of HNC. For those returning to work, late effects may affect capacity.

4108 Background: Neoadjuvant chemoradiation followed by surgery is standard of care for locally advanced rectal cancer. The impact of downstaging on prognosis when pathologic complete response (pCR) cannot be achieved remains unclear. The aim of this study was to evaluate whether downstaging impacts prognosis in patients with cII vs. cIII rectal cancer. Methods: We identified from our colorectal cancer database 233 patients with primary cII and cIII rectal cancer staged by CT and ERUS/MRI who received 5FU-based chemoradiation followed by R0 surgery after a median interval of 7 weeks during 1997–2007. Median radiotherapy dose was 5040 cGy. We excluded 58 patients with pCR and. Compared among the remaining 175 patients pathologic downstaging (cII to ypI, cIII to ypII or ypI) vs. No pathologic downstaging (c stage ≤ yp stage). Outcomes evaluated were 5-year overall survival, 3-year recurrence-free survival, overall recurrence, local recurrence and distant recurrence. Results: Median age was 58 years and median follow-up was 48 months. Patients with cII vs. cIII stage were statistically comparable regarding demographics, chemoradiation regimen, interval to surgery after neoadjuvant treatment, tumor distance from anal verge, operations performed and follow-up. The incidence of downstaging was increased in stage cIII vs. cII patients (68% vs. 21%, p <0.001). With the exception of local recurrence rates, downstaging resulted in significantly improved cancer outcomes for cIII but not cII ( Table ). Conclusions: Downstaging without pCR is a significant prognostic factor for patients with stage cIII rectal cancer. A larger sample size is required to confirm lack of downstaging benefits in stage cII. [Table: see text] No significant financial relationships to disclose.

e12620 Background: Neoadjuvant chemotherapy (NAC) is commonly utilized in women with locally advanced breast cancer, usually followed by surgery and radiation therapy (RT). Many studies aimed to address the risk factors contributing to a higher incidence of lymphedema in patients with breast cancer. Our group previously reported the extent of surgery increases the risk of lymphedema. Adjuvant chemotherapy with taxane-based regimens are associated with an increased risk of lymphedema likely due an increase in interstitial extracellular fluid volume therefore resulting in fluid retention. This study aims to directly compare and characterize the risk of lymphedema in patients receiving paclitaxel versus docetaxel-based NAC. Methods: This is a retrospective study approved by our institutional review board. The study included women with breast cancer treated consecutively at our institution with taxane-based NAC followed by surgery and RT from 2006 to 2018. Patients and tumor characteristics including age, race, body mass index (BMI), clinical stage, hormone receptor, HER2 status, type of surgery, RT techniques, and type of NAC (Paclitaxel versus Docetaxel), and its association to risk of lymphedema were analyzed using univariable and multivariable binary logic regression tests. Lymphedema was assessed before RT and at follow up visits, and was identified by >2.0-cm increase in arm circumference, or >10% increase in limb volume, or new self-reported lymphedema symptoms. Results: A total of 263 patients treated with either paclitaxel or docetaxel-based NAC were identified and analyzed. At a median follow up of 28.4 months (range 3.5-158.7 months). 26.2% (69/263) of patients developed lymphedema. On a multivariable analysis, patients who underwent axillary lymph node dissection (ALND) had a significantly higher rate of lymphedema (42.6%) compared to those who had only a sentinel lymph node biopsy (SLNB, 10.5%, p<0.05). Regardless of the type of surgery, there was no significant difference in rates of lymphedema between patients who received paclitaxel versus docetaxel-based NAC (28.7% vs 21.3%). However, among high-risk patients who underwent mastectomy with ALND, NAC with Paclitaxel was associated with a significantly higher rate of lymphedema compared to docetaxel (56.8% vs 22.7%, RR 2.50, p<0.05). Conclusions: This represents one of the largest studies examining the impact of taxane-based NAC on the risk of lymphedema in women with breast cancer. In this study, paclitaxel-based NAC was associated with a significantly higher risk of lymphedema in women who underwent mastectomy and ALND compared to docetaxel based chemotherapy. A larger, balanced, prospective study is warranted to verify this previously unidentified lymphedema risk from paclitaxel and guide individualized NAC decision.
