ObjectiveWhether the original dosimetric constraints of neuro-optic structures (NOS) are appropriate for patients with nasopharyngeal carcinoma (NPC) undergoing intensity-modulated radiotherapy (IMRT) remains controversial. The present study compared the survival rates and radiation-induced optic neuropathy (RION) occurrence between T4 NPC patients whose NOS were irradiated with a near maximum dose received by 2% of the volume (D2%) >55 Gy and ≤55 Gy. Moreover, the NOS dosimetric parameters and their correlation with RION occurrence were also evaluated.MethodsIn this retrospective study, 256 T4 NPC patients treated with IMRT between May 2009 and December 2013 were included. Patient characteristics, survival rates, dosimetric parameters, and RION incidence were compared between the D2% ≤55 Gy and D2% >55 Gy groups.ResultsThe median follow-up durations were 87 and 83 months for patients in the D2% >55 Gy and D2% ≤55 Gy groups, respectively. The 5-year local recurrence-free survival rates were 92.0 and 84.0% in the D2% >55 Gy and D2% ≤55 Gy groups (P = 0.043), respectively. There was no significant difference in the 5-year overall survival (OS) between both groups (D2% >55 Gy, 81.6%; D2% ≤55 Gy, 79.4%; P = 0.586). No patients developed severe RION (Grades 3–5), and there was no significant difference (P = 0.958) in the incidence of RION between the two groups. The maximum dose of NOS significantly affected the RION incidence, with a cutoff point of 70.77 Gy.ConclusionAppropriately loosening NOS dosimetric constraints in order to ensure a more sufficient dose to the target volume can provide a better 5-year local recurrence-free survival and acceptable neuro-optic toxicity in T4 NPC patients undergoing IMRT.

Local Recurrence Free Survival

1120 Background: After breast conserving surgery, radiotherapy leads to a better overall survival. In addition to whole breast radiotherapy (WBRT) a boost to the tumor bed leads to a better local control. The tumor bed boost is usually added after WBRT or can be done intraoperative (IORT). Belletti et al. (Clin Cancer Res., 2008) described positive effects, an antitumoral effect and modulation of microenvironment after IORT with 50kV x-rays. A matched pair analysis was performed to investigate the impact of IORT boost on overall survival compared to standard external beam boost. Methods: Between 2002 – 2009, 370 patients were treated for breast cancer with WBRT + boost (external beam (EBRT) boost n = 146, IORT boost n =224). A matched pair analysis (1:1 propensity score matching for age, TNM, grading, hormonal treatment and chemotherapy) for overall survival and local recurrence free survival could be done for 53 pairs. All patients underwent breast conserving surgery and WBRT with 46-50Gy. 53 patients received an EBRT boost with 16Gy (2Gy/fraction, dedicated linear accelerator) and 53 patients received an IORT boost with 20Gy (INTRABEAM system, 50kV x-rays). Median follow-up was 6 months (range, 1-77 months) for the EBRT boost patients and 56 months (range, 2-97 months) for IORT boost patients. Kaplan Meier estimates were performed for overall survival and local recurrence free survival. Results: IORT boost patients had a longer follow-up than EBRT boost patients. Despite the difference in follow-up times, there was a strong trend towards better overall survival after IORT boost (90.2% vs. 62.3%, p = 0.375). One local recurrence was present in each group (EBRT boost after 15 months, local recurrence free survival 95%; IORT boost after 12 months, local recurrence free survival 98.1%). Conclusions: IORT given as a boost seems to have a positive impact on overall survival in breast cancer patients after breast conserving surgery. To identify such an effect a prospective randomized trial should be conducted.

Local Recurrence Free Survival

AbstractThis study retrospectively reviewed 183 cases of adenoid cystic carcinoma treated over 40 years. The local recurrence free survival rate was 68.2 per cent at five years and 40.8 per cent at 10 years. At 10 years, local recurrence free survival was significantly worse following radiotherapy alone (0 per cent), compared with surgery alone (41.8 per cent, p = 0.004) or combined with post-operative radiotherapy (43.5 per cent, p = 0.001). Neither tumour stage three or four, perineural invasion, solid subtype nor involved margins predicted local recurrence. Treatment with radiotherapy alone resulted in worse survival than surgery alone (p = 0.002) or combined with post-operative radiotherapy (p = 0.001). Survival rates following local recurrence (n = 34) were higher following surgery (p = 0.006) but not significantly improved following radiotherapy (p = 0.139). Chemotherapy for distant metastases did not prolong survival (p = 0.747) but did result in improved eating and aesthetics scores, while decreasing overall physical health. These results indicate that surgery is preferable for primary and recurrent adenoid cystic carcinoma of the head and neck. The incidence of local recurrence following surgery and postoperative radiotherapy was similar to surgery alone cases although the latter had less adverse prognostic features. Contemporary chemotherapy may benefit quality of life but not survival in patients with distant metastases due to adenoid cystic carcinoma of the head and neck.

Aims The purpose of this study was to investigate the potential for achieving local and systemic control after local recurrence of a chondrosarcoma of bone Patients and Methods A total of 126 patients with local recurrence (LR) of chondrosarcoma (CS) of the pelvis or a limb bone were identified from a prospectively maintained database, between 1990 and 2015 at the Royal Orthopaedic Hospital, Birmingham, United Kingdom. There were 44 female patients (35%) and 82 male patients (65%) with a mean age at the time of LR of 56 years (13 to 96). The 126 patients represented 24.3% of the total number of patients with a primary CS (519) who had been treated during this period. Clinical data collected at the time of primary tumour and LR included the site (appendicular, extremity, or pelvis); primary and LR tumour size (in centimetres); type of operation at the time of primary or LR (limb-salvage or amputation); surgical margin achieved at resection of the primary tumour and the LR; grade of the primary tumour and the LR; gender; age; and oncological outcomes, including local recurrence-free survival and disease-specific survival. A minimum two years’ follow-up and complete histopathology records were available for all patients included in the study. Results For patients without metastases prior to or at the time of local recurrence, the disease-specific survival after local recurrence was 62.5% and 45.5% at one and five years, respectively. After univariable analysis, significant factors predicting disease-specific survival were grade (p < 0.001) and surgical margin (p = 0.044). After multivariable analysis, grade, increasing age at the time of diagnosis of local recurrence, and a greater time interval from primary surgery to local recurrence were significant factors for disease-specific survival. A secondary local recurrence was seen in 26% of patients. Wide margins were a good predictor of local recurrence-free survival for subsequent recurrences after univariable analysis when compared with intralesional margins (p = 0.002) but marginal margins did not reach statistical significance when compared with intralesional margins (p = 0.084) Conclusion In cases of local recurrence of a chondrosarcoma of bone, we have shown that if the tumour is non-metastatic at re-staging, an increase in disease-specific survival and in local recurrence-free survival is achievable, but only by resection of the local recurrence with a wide margin.
