Lower Local Recurrence Rate

Between 1962 and 1984, a total of 433 patients were treated at Yale-New Haven Hospital with conservative surgery and radiation therapy (CS + RT) to the intact breast. As of January 1990, with a minimum assessable follow-up of 5 years and a median follow-up of 8.21 years, there have been a total of 50 breast recurrences resulting in a 5-year actuarial breast recurrence rate of 8%. Of all clinical factors tested, young age was the most significant prognostic factor for local recurrence (P less than .03). In addition, patients with pathologically involved lymph nodes were noted to have a lower local recurrence rate than patients with pathologically negative axillae (P less than .05). These findings were especially notable given the fact that the node-positive group had a higher percentage of T2 tumors and a higher percentage of patients in the young age group. These paradoxical findings, however, may be explained by the fact that 88% of the node-positive patients underwent adjuvant systemic therapy in the form of either systemic chemotherapy or hormonal therapy, while only 8% of node-negative patients underwent any adjuvant systemic therapy. When analyzed as a function of adjuvant therapy, those patients receiving adjuvant therapy had a lower local recurrence rate than those patients not receiving adjuvant therapy (P less than .08). We conclude that adjuvant systemic therapy impacts on the ipsilateral breast recurrence rate in patients treated with CS + RT. The implications of this study in light of the widespread use of adjuvant systemic therapy are discussed.

Background Cold polypectomy has been increasingly used to remove diminutive colorectal polyps. We evaluated the local recurrence rate of diminutive polyps at the 1-year follow-up after cold forceps polypectomy (CFP). Methods In a prospective, multicenter, observational cohort study, patients with diminutive colorectal polyps ( ≤ 5 mm) were treated by CFP using jumbo forceps followed by magnified narrow-band imaging (NBI). Patients were assessed for local recurrence at 1-year follow-up. Risk factors associated with local recurrence were analyzed using logistic regression analysis. Results Overall, 955 lesions were resected in 471 patients who completed the 1-year follow-up. The endoscopic complete resection rate was 99.4 %. Immediate and delayed bleeding occurred in 0.8 % and 0.2 % of cases, respectively, with no perforations observed. Local recurrence occurred in 2.1 % of cases at the 1-year follow-up. Univariable analyses indicated that polyps > 3 mm (P < 0.01) and immediate bleeding (P = 0.04) were significantly associated with local recurrence. A trend was observed for patients ≥ 65 years (P = 0.06) and fractional resection (P = 0.09). Multivariable analyses confirmed that lesions > 3 mm were significantly associated with local recurrence (odds ratio 3.4, P = 0.02). Conclusions CFP with jumbo forceps followed by NBI-magnified observation had a low local recurrence rate and is an acceptable therapeutic option for diminutive colorectal polyps. Although we recommend limiting the use of CFP with jumbo forceps to polyps ≤ 3 mm in size, future comparative studies are needed to make recommendations on cold polypectomy using either forceps or snares as the preferred approach for diminutive polyp resection.

Object Whole-brain radiation therapy (WBRT) has been the traditional approach to minimize the risk of intracranial recurrence following resection of brain metastases, despite its potential for late neurotoxicity. In 2007, the authors demonstrated an equivalent local recurrence rate to WBRT by using stereotactic radiosurgery (SRS) to the operative bed, sparing 72% of their patients WBRT. They now update their initial experience with additional patients and more mature follow-up. Methods The authors performed a retrospective review of all cases involving patients with limited intracranial metastatic disease (≤ 4 lesions) treated at their institution with SRS to the operative bed following resection. No patient had prior cranial radiation and WBRT was used only for salvage. Results From November 2000 to June 2009, 52 patients with a median age of 61 years met inclusion criteria. A single metastasis was resected in each patient. Thirty-four of the patients each had 1 lesion, 13 had 2 lesions, 3 had 3 lesions, and 2 had 4 lesions. A median dose of 1500 cGy (range 800–1800 cGy) was delivered to the resection bed targeting a median volume of 3.85 cm3 (range 0.08–22 cm3). With a median follow-up of 13 months, the median survival was 15.0 months. Four patients (7.7%) had a local recurrence within the surgical site. Twenty-three patients (44%) ultimately developed distant brain recurrences at a median of 16 months postresection, and 16 (30.7%) received salvage WBRT (8 for diffuse disease [> 3 lesions], 4 for local recurrence, and 4 for diffuse progression following salvage SRS). The median time to WBRT administration postresection was 8.7 months (range 2–43 months). On univariate analysis, patient factors of a solitary tumor (19.0 vs 12 months, p = 0.02), a recursive partitioning analysis (RPA) Class I (21 vs 13 months, p = 0.03), and no extracranial disease on presentation (22 vs 13 months, p = 0.01) were significantly associated with longer survival. Cox multivariate analysis showed a significant association with longer survival for the patient factors of no extracranial disease on presentation (p = 0.01) and solitary intracranial metastasis (p = 0.02). Among patients with no extracranial disease, a solitary intracranial metastasis conferred significant additional survival advantage (43 vs 10.5 months, p = 0.05, log-rank test). No factor (age, RPA class, tumor size or histological type, disease burden, extent of resection, or SRS dose or volume) was related to the need for salvage WBRT. Conclusions Adjuvant SRS to the metastatic intracranial operative bed results in a local recurrence rate equivalent to adjuvant WBRT. In combination with SRS for unresected lesions and routine imaging surveillance, this approach achieves robust overall survival (median 15 months) while sparing 70% of the patients WBRT and its potential acute and chronic toxicity.

609 Background: Though total mesorectal excision (TME) has proved to effectively decrease local recurrence rate of mid/low rectal cancer, the efficacy of preoperative radiotherapy in Asian patients remains unclear. The present study aimed to compare the efficacy of TME alone versus TME after preoperative radiotherapy and simultaneous chemotherapy with capecitabine plus oxaliplatin in Chinese patients with stage II and III mid/low rectal adenocarcinoma. Methods: Patients (n=192) aged between 18 and 70 years enrolled from March 23, 2008 to August 2, 2012 were randomly divided into two groups. Group A (n=97) received preoperative radiotherapy and simultaneous chemotherapy [46-50 GY/23-25 with oxaliplatin 100 mg/m2 (D1) and capecitabine 1,000 mg/m2 (bid, D1-15), repeated since D22], which was followed by TME; while patients in group B (n=95) underwent TME alone. While disease free survival (DFS) was the primary endpoint; the following were evaluated as secondary endpoints: pathological response rate, pathologic complete response (PCR) rate, anal preservation rate, local recurrence rate, distant metastasis rate, acute toxic effects, and late toxic effects. Results: Excluding the drop outs, 90 and 94 patients were analyzed in group A and B, respectively. The median follow-up time was 29 (range: 0 to 59) months. PCR was achieved for 32 patients (35.6%). The median survival time and overall survival (OS) rate in group A were 24 months and 92.5% (95% CI: 88.3-96.7), respectively; while the same were 34 months and 88.7% (95% CI: 84.8-92.6) in group B. The median DFS time was 22 and 31 months in group A and B, respectively; and the overall DFS was 86.1% (95% CI: 81.6-90.6%) and 80.6% (95% CI: 74.8-85.4%) in both groups. No significant differences were observed between groups in OS rate (p=0.323), overall DFS, (p=0.612), and anal preservation rate (p=0.849). Conclusions: Preoperative radiotherapy combined with chemotherapy of capecitabine plus oxaliplatin could result in higher PCR rate. However, studies with long follow up and large sample are recommended to demonstrate the efficacy of this treatment strategy over TME alone. Clinical trial information: ChiCTR-TRC-00000122.

Abstract Background Transanal total mesorectal excision (TaTME) for mid and low rectal cancer has been shown to improve short-term outcomes, mostly due to lower conversion rates and with improved quality of the specimen. However, robust long-term oncological data supporting the encouraging clinical and pathological outcomes are lacking. Methods All consecutive patients undergoing TaTME with curative intent for mid or low rectal cancer in two referral centers in The Netherlands between January 2012 and April 2016 with a complete and minimum follow-up of 36 months were included. The primary outcome was local recurrence rate. Secondary outcomes were disease-free survival, overall survival and development of metastasis. Results There were 159 consecutive patients. Their mean age was 66.9 (10.2) years and 66.7% of all patients were men. Pathological analysis showed a complete mesorectum in 139 patients (87.4%), nearly complete in 16 (10.1%) and an incomplete mesorectum in 4 (2.5%). There was involvement of the CRM (< 1 mm) in one patient (0.6%) and no patients had involvement of the distal margin (< 5 mm). Final postoperative staging after neoadjuvant therapy was stage 0 in 11 patients (6.9%), stage I in 73 (45.9%), stage II in 31 (19.5%), stage III in 37 (23.3%) and stage IV in 7 (4.4%). The 3-year local recurrence rate was 2.0% and the 5-year local recurrence rate was 4.0%. Median time to local recurrence was 19.2 months. Distant metastases were found in 22 (13.8%) patients and were diagnosed after a median of 6.9 months (range 1.1–50.4) months. Disease-free survival was 92% at 3 years and 81% at 5 years. Overall survival was 83.6% at 3 years and 77.3% at 5 years. Conclusions The long-term follow-up of the current cohort confirms the oncological safety and feasibility of TaTME in two high volume referral centers for rectal carcinoma. However, further robust and audited data must confirm current findings before widespread implementation of TaTME.
